Field of Invention
[0001] The present invention relates to a powder container for containing powder such as toner, and an imaging apparatus that transports the powder from the powder container to a transport destination. Background of the Invention
[0002] In imaging apparatus, such as copiers, printers, or fax machines, using an electrophotographic process, a latent image formed on a photoreceptor is developed with toner supplied by a developing device. Since toner is consumed through latent image development, it is necessary to refill the developer device with toner. Therefore, a toner replenishment device such as a powder supply device supplied in an apparatus body drives toner from a toner container such as a powder container to the developing device, so that the developing device can be replenished with toner. The developing device that can be refilled with toner, as described above, enables continuous development. In addition, the toner container is detachably attached to the toner replacement device. If the toner contained in the toner container runs out, the toner container is replaced with one containing the new toner.
[0003] In relation to the toner container releasably attached to the toner replacement device, a toner container is known to have a helical rib formed on a cylindrical inner surface of a toner storage element to contain the toner ( see Patent Document 1: Japanese Patent Application open to public inspection No. 2003-241496, Patent Document 2: Japanese Patent Application open to public inspection No. 2005-221825, Patent Document 3: Japanese Patent Application No. 4,342,958, Patent Document 4: Japanese Patent Application open to public inspection No. 2002-202,656, and Patent Document 5: Japanese Patent Application open to public inspection No. 2003233.247). In such a toner container, the toner storage element is rotated while the toner container is fixed to the toner replacement device, so that the stored toner is transported from one end to the other end in the direction of rotation of the toner. axle. Thereafter, the toner is discharged through an opening arranged at the other end of the toner replacement device element.
[0004] Regarding the toner container that carries the toner stored inside it from one end to the other end, by rotating the toner storage element, Patent Document 6 (Japanese Patent Application open to public inspection No. 2009 -276659) describes a toner container into which a drive nozzle attached to the toner replacement device is inserted through the opening at the other end of the toner storage element. Specifically, a toner receiving opening is formed in the vicinity of a front end of the drive nozzle inserted into the toner container in the insertion direction. The drive nozzle receives toner from the toner storage element through the toner receiving opening when it is inserted into the toner container, and drives the toner into the main body of the toner replacement device. In the toner container, a nozzle insert member having a nozzle receiving opening for inserting the driving nozzle is fixed inside the opening at the other end of the toner storage element. The toner container also includes an open/close member that closes the nozzle receiving opening prior to insertion of the drive nozzle and opens the nozzle receiving opening with insertion of the drive nozzle.
[0005] The toner container described in Patent Document 6 can maintain the closed state of the nozzle receiving opening until the driving nozzle is inserted, so that it is possible to prevent the occurrence of toner leakage or toner scattering beforehand. the toner container is attached to the toner replacement device. When the toner container is attached to the toner replacement device, the toner stored in the toner storage element is received through the toner receiving opening formed in the vicinity of the front end of the driving nozzle inserted in the insertion direction and transported to the main body of the toner replacement device through the drive nozzle, while the nozzle receiving opening is being closed by the driving nozzle. Therefore, even when the toner container is attached to the toner replacement device, it is possible to prevent toner leakage or scattering.
[0006] However, in the configuration described in Patent Document 6, when the toner container is attached to the toner replacement device, the outer surface of the drive nozzle inserted into the toner storage element comes into contact with the toner in the element. of toner storage. Therefore, when the drive nozzle is removed from the toner container, part of the toner in contact with the drive nozzle may remain attached to the drive nozzle and may pass through the nozzle receiving opening together with the drive nozzle , so that toner may leak from the nozzle receiving opening resulting in toner scattering.
[0007] In the above explanation, a problem that occurs with a toner container that contains toner such as powder is explained. However, in any powder containing powder other than toner, if the container is configured to transmit and discharge the powder from the inside to the outside through the insertion of a conduction nozzle attached to a powder conduction device, the spilled powder together with the removal of the conduction nozzle may be dispersed.
[0008] The present invention was made in view of the circumstances mentioned above, and an objective of the same is to provide a powder container that discharges the powder from the inside to the outside through the insertion of a conduction nozzle and which it can prevent the dispersion of the poured powder when the drive nozzle is removed, and provide an imaging apparatus that includes the powder container. Description of the Invention
[0009] According to an embodiment of the present invention, there is provided a powder container which is to be fixed to a powder transport apparatus with a longitudinal direction of the powder container parallel to the horizontal direction. The powder transport apparatus includes a transport nozzle, provided with a powder receiving opening for receiving powder from the powder container, for transporting the powder; an opening/closing element for opening and closing the powder receiving opening; a flange provided for the opening/closing element; a tilting element for tilting the opening/closing element to close the powder receiving opening; and a container fitting section to which a part of the powder container is to be fitted. The powder container includes a conveyor, disposed within the powder container, for conveying powder from a second end of the powder container to a first end along the longitudinal direction of the powder container; a container opening extending from the first end of the powder container; a nozzle receiving opening provided in the container opening into which the transport nozzle provided for the powder transport apparatus is to be inserted; and a projection portion provided in the container opening, to project against the flange so as to move the opening/closing element to open the receiving opening. When the powder container is fixed to the powder transport apparatus, the container opening is fitted to the container adjustment section, and the flange and the tilting element are housed in an inner space of the container opening.
[0010] According to another embodiment of the present invention, there is provided a powder container which is removably attachable to an imaging apparatus. The powder container includes a container body, including a container opening at a first end, and which contains imaging powder; a conveyor disposed within the container body for conveying powder from a second end of the container body to the first end along a longitudinal direction of the container body; a nozzle receiver disposed at the container opening and including a nozzle receiving opening for receiving a powder conduction nozzle from the imaging apparatus for guiding the powder conduction nozzle into the container body; and an emptying portion, which receives the powder from the conveyor and rotates to empty the powder received from the bottom upwards into the container body so as to move the powder to a powder receiving opening of the powder conveying nozzle. . The nozzle receiver includes: a shutter for opening and closing the nozzle receiving opening; a support part to support the shutter so as to move; an opening, arranged adjacent to the support part, for communicating with the powder receiving opening of the driving nozzle inserted in the nozzle receiver. The support portion and the opening disposed adjacent the support portion are configured to alternately prevent the powder receiving opening.
According to yet another embodiment of the present invention, there is provided a powder container which is removably attachable to an imaging apparatus. The powder container includes a container body including a container opening at a first end and containing imaging powder; a conveyor disposed within the container body for conveying powder from a second end of the container body to the first end along a longitudinal direction of the container body; a nozzle receiver disposed at the container opening and including a nozzle receiving opening for receiving a powder conduction nozzle from the imaging apparatus for guiding the powder conduction nozzle into the container body; and an emptying portion, which projects into the container body and which includes a ridge. The nozzle receiver includes: a shutter for opening and closing the nozzle receiving opening; a support part to support the shutter so as to move; and an opening, arranged adjacent to the support part, for communicating with the powder receiving opening of the drive nozzle inserted in the nozzle receiver. The crest of the deflation portion confronts the support portion of the nozzle receiver.
[0012] In the toner container disclosed in Patent Document 6, the position of the edge of the container opening in the longitudinal direction and the position of the edge of the nozzle inserter on the side where the nozzle receiving opening is formed in the longitudinal direction they are the same. With this positional relationship, nothing can prevent the dispersion of the poured powder from the nozzle receiving opening when the driving nozzle is removed from the powder container. Therefore, toner scattering can easily occur. According to the invention, the mouthpiece receiving opening is arranged in the inner cylindrical lower part of the container opening. Therefore, the edge of the container opening protrudes with respect to the edge of the nozzle insert member, where the nozzle receiving opening is formed, in the longitudinal direction. The protruding part can prevent the dispersion of the poured powder from the nozzle receiving opening when the driving nozzle is removed from the powder container. Consequently, it is possible to prevent scattering of toner. Advantageous Effects of the Invention
[0013] According to the invention, it is possible to prevent the dispersion of the poured powder when a conduction nozzle is removed from a powder container. Brief Description of Drawings

Preferred Embodiments of the Invention First Implementation
[0098] Exemplary embodiments of a copier (hereinafter described as a copier 500) as an imaging apparatus in accordance with the present invention will be explained below.
[0099] Figure 2 is a general configuration diagram of the common copier 500 from the first to the twentieth embodiment. Copier 500 includes a copier body (hereinafter, described as a printer 100), a sheet feed table (hereinafter, described as a sheet feeder 200), and a scanner (hereinafter, described as a scanner 400) mounted on printer 100.
[0100] The 32 toner containers (Y, M, C, K) that serve as four corresponding color powder containers (yellow, magenta, cyan, black) are detachably affixed (replaceable) to a retaining section of container 70 provided at the top of the printer 100. An intermediate transfer unit 85 is disposed below the container retaining section 70.
[0101] The intermediate transfer unit 85 includes an intermediate transfer belt 48, four primary transfer bias rollers 49 (Y, M, C, K), a secondary transfer support roller 82, a plurality of tension rollers , an intermediate transfer cleaner (not shown), and the like. The intermediate transfer belt 48 is stretched and supported by a plurality of rollers and is infinitely moved in the direction of the arrow in Figure 2 along with rotation of the secondary transfer cradle roller 82 which is one of the rollers.
[0102] In the printer 100, four imaging units 46 (Y, M, C, K), corresponding to the respective colors are arranged in a parallel way, so as to confront the intermediate transfer belt 48. Four replacement devices Toner containers 60 (Y, M, C, K) are arranged below the four toner containers 32 (Y, M, C, K), respectively. Toner replacement devices 60 (Y, M, C, K) supply (reset) toner contained in toner containers 32 (Y, M, C, K) to developing devices (powder-using units) of forming units of image 46 (Y, M, C, K), corresponding to the respective colors.
[0103] As illustrated in Figure 2, the printer 100 includes an exposure device 47 serving as a latent imaging means below the four imaging units 46. The exposure device 47 exposes the surfaces of photoreceptors 41 (a to be described further below) to light based on image information from an original image read by scanner 400 or based on input of image information from an external device, such as a personal computer, so that the electrostatic latent images are formed on the surfaces of the photoreceptors 41. The exposure device 47 of the printer 100 employs a laser scanning system using a laser diode. However, display means having other configurations, for example having an LED array, can be used.
[0104] Figure 3 is a schematic diagram of an overall configuration of the 46Y imaging unit for yellow.
[0105] The 46Y imaging unit includes a 41Y drum-shaped photoreceptor as a latent image carrier. The 46Y imaging unit also includes a loading roller 44Y as a loading means, a developing device 50Y of a developing media, a photoreceptor cleaning device 42Y, and a neutralizing device (not shown). which are arranged around the 41Y drum. Imaging processes (a loading process, an exposure process, a developing process, a transfer process, and a cleaning process) are performed on the 41Y drum so that a yellow image is formed on the 41Y drum .
[0106] The other three imaging units 46 (H, C, K) have almost the same settings as the imaging unit 46Y for yellow, except that the colors of the toner to be used are different, and the images corresponding to the respective toner colors are formed in the imaging units 46 (H, C, K). Hereafter, the explanation of the other three imaging units 46 (M, C, K) will be suitably omitted, and only the imaging unit 46Y will be explained for yellow.
[0107] The 41Y drum is rotated clockwise in figure 3 by a drive motor (not shown). The surface of the 41Y drum is uniformly loaded in a forward position of (the loading process) 44Y loading roller. The surface of the 41Y photoreceptor then reaches a position of laser light irradiation L emitted by the exposure device 47, at which an electrostatic latent image for yellow is formed via exposure scanning (exposure process). The surface of the 41Y drum then reaches a front position facing the 50Y developer device, where the electrostatic latent image is developed and a yellow toner image is formed (development process).
[0108] The four primary transfer bias rollers 49 (Y, M, C, K) of the intermediate transfer unit 85 and the drums 41 (Y, M, C, K) press the intermediate transfer belt 48, so which primary transfer passes are formed. Transfer bias with polarity opposite to toner polarity is applied to primary transfer bias rollers 49 (Y, M, C, K).
[0109] The surface of the 41Y drum, on which the toner image is formed through the developing process, reaches the primary transfer pass zone facing the 49Y bias primary transfer roller through the intermediate transfer belt 48, and the toner image on drum 41Y is transferred to intermediate transfer belt 48 in the primary transfer pass (primary transfer process). At this point, a small amount of untransferred toner remains in drum 41Y. The surface of the drum 41Y, from which the toner image is transferred to the intermediate transfer belt 48 in the primary transfer pass zone, reaches a position facing the drum cleaning device 42Y. In this position, untransferred toner remaining in drum 41Y is mechanically collected by a (cleaning process) of wiper blade 42a. The surface of the 41Y photoreceptor finally reaches a position facing the neutralizing device (not shown), where the residual potential in the 41Y photoreceptor is removed. In this way, a series of imaging processes performed on photoreceptor 41Y is completed.
[0110] The above imaging processes are also performed in the other imaging units 46 (H, C, K) in the same way as in the imaging unit 46Y for yellow. Specifically, the display device 47 disposed below the image forming units 46 (M, C, K) emits laser light L based on the image information to the photoreceptors 41 (M, C, K) of the image forming units. image 46 (M, C, K). More specifically, the display device 47 emits laser light L from a light source and irradiates photoreceptors 41 (M, C, K) with laser light L through a plurality of optical elements during light scanning. of laser L by a polygonal mirror being rotated. Subsequently, the toner images of the respective colors formed on the photoreceptors 41 (M, C, K) through the developing process are transferred to the intermediate transfer belt 48.
[0111] This time, the intermediate transfer belt 48 moves in the direction of the arrow in figure 2 and sequentially passes through the primary transfer passes of the primary transfer bias rollers 49 (Y, M, C, K). Consequently, the toner images of the respective colors formed on the photoreceptors 41 (Y, M, C, K) are superimposed on the intermediate transfer belt 48 as primary transfer, so that a color toner image is formed on the transfer belt. intermediate 48.
[0112] The intermediate transfer belt 48, color toner image is formed by superimposing the toner images of the respective colors, reaches a position facing a secondary transfer roller 89. In this position, the secondary transfer support roller 82 and secondary transfer roller 89 press down on intermediate transfer belt 48 so that a secondary transfer pass is formed. The color toner image formed on the intermediate transfer belt 48 is transferred to a recording medium P, such as a sheet of paper, transported to the position of the secondary transfer pass. This time, the untransferred toner that has not been transferred to the recording medium P remains on the intermediate transfer belt 48. The intermediate transfer belt 48 that has passed through the secondary transfer pass reaches the position of the intermediate transfer cleaner (not shown), where untransferred toner on the surface is collected. In this way, a series of transfer processes performed on the intermediate transfer belt 48 is completed.
[0113] The movement of recording medium P will be explained below.
[0114] The recording medium P is transported to the secondary transfer pass zone from a feed tray 26 of the sheet feeder 200 arranged below the printer 100 via a feed roller 27, a pair of registration rollers 28, and so on. Specifically, a plurality of embossing media P is stacked on the feed tray 26. When the feed roller 27 is rotated to the left in Figure 2, the uppermost embossing medium P is fed to a pass zone between two rollers of the pair of register rollers 28.
[0115] The recording medium P transported to the pair of registration rollers 28 temporarily stops at the position of the pass between the rollers of the pair of registration rollers 28, whose rotation is to be stopped. The pair of registration rollers 28 is rotated to transport the recording medium P to the secondary transfer pass in accordance with the moment when the color toner image on the intermediate transfer belt 48 reaches the secondary transfer pass zone . Consequently, a desired color image is formed on the recording medium P.
[0116] The recording medium P on which the color toner image is transferred in the secondary transfer pass zone is transported to the position of a holder 86. In the holder 86, the transferred color toner image on the surface of the recording support it is fixed to the recording medium P by the action of heat and pressure applied by a fastening strap and a pressure roller. The recording medium P which has passed through the fixing device 86 is discharged out of the apparatus through a pass between the rollers of a pair of discharge rollers 29. The recording medium P is discharged out of the apparatus by the pair. of discharge rollers 29 is sequentially stacked, as an output image, in a section of stack 30. In this way, a series of imaging processes on the copier 500 is completed.
[0117] A configuration and operation of the developing device 50 in the imaging unit 46 will be explained in detail below. In the following the 46Y imaging unit for yellow will be explained by way of example. However, the same applies to imaging units 46 (M, C, K) for the other colors.
[0118] As illustrated in Figure 3, the developer device 50Y includes a developer roller 51Y, a 52Y dosing blade, two 55Y developer transport screws, a 56y toner density sensor, and the like. The 51Y developing roller confronts the 41Y drum. The 52Y dosing blade confronts the 51Y developing roller. The two 55Y developer transport screws are disposed within two developer housing portions (53Y, 54Y). The 51Y developer roller includes a magnet roller fixed within it and a sleeve that rotates around the magnet roller. The two-component developer G formed from carrier and toner is stored in the first developer accommodating portion 53Y and in the second developer accommodating portion 54Y. The second developer housing portion 54Y communicates with a 64Y toner dump passage through an opening formed at the top thereof. The 56y toner density sensor detects the density of the toner in developer G stored in the developer housing portion 54Y.
[0119] The developer G in the developer device 50 circulates between the first developer accommodation portion 53Y and the second developer accommodation portion 54Y by being agitated by the two developer transport screws 55Y. The developer G in the first developer housing portion 53Y is supplied to and loaded onto the sleeve surface of the developing roller 51Y due to the magnetic field formed by the magnet roller on the developing roller 51Y, while the developer G is being transported by one of the 55Y developer transport screws. The developer roller sleeve 51Y rotates to the left, as indicated by an arrow in figure 3, and the developer L loaded on the developer roller 51Y moves on the developer roller 51Y, along with the rotation of the sleeve. This time, the toner in developer L electrostatically adheres to the conveyor by being charged to the potential opposite to the polarity of the conveyor due to triboelectric charging with the conveyor in developer G, and is conveyed on the developing roller 51Y together with the conveyor that is attracted by the magnetic field formed on the 51Y developing roller.
[0120] The developer G carried on the developing roller 51Y is driven in the direction of the arrow in figure 3 and reaches a dosing portion where the dosing blade 52Y and the developing roller 51Y are facing each other. The developer G on the developing roller 51Y is adjusted to a suitable level by passing through the dosing portion, and then transported to a developing area facing the photoreceptor 41Y. In the developing area, toner in developer G adheres to the latent image formed on drum 41Y by an electric field formed between developer roller 51Y and drum 41Y. The developer G remaining on the surface of the developing roller 51Y which has passed through the developing area L reaches the top of the first developer housing portion 53Y along with the rotation of the sleeve, where the developer G is separated from the developing roller 51Y.
[0121] The toner density of developer G in developer device 50Y is set to a predetermined range. Specifically, the toner contained in the 32Y toner container is supplied to the second developer housing portion 54Y through the 60Y toner reset device (to be described later), in accordance with the amount of toner consumed from the developer G in the 50Y developing device through developing.
[0122] The toner supplied to the second developer housing portion 54Y circulates between the first developer housing portion 53Y and the second developer housing portion 54Y by being mixed and agitated with the developer G by the two developer transport screws 55Y .
[0123] Toner Replacement Devices 60 (Y, M, C, K) will be explained below.
[0124] Figure 4 is a schematic diagram of how the 32Y toner is attached to the 60Y toner replacement device. Figure 5 is a schematic perspective view of how the four toner containers 32 (Y, M, C, K) are attached to the container retaining section 70.
[0125] The toner contained in the toner containers 32 (Y, M, C, K) attached to the container holding section 70 of the printer 100 is suitably supplied to the developing devices 50 (Y, M, C, K) by the devices Toner Replacement 60 (Y, M, C, K) for the respective colors, according to the consumption of toner in the developing devices 50 (Y,, C, K) for the respective colors. This time, the toner in toner containers 32 (Y, M, C, K) is replenished by the toner replacement devices 60 (Y, M, C, K) provided for the respective colors. The four 60 Toner Replacement Devices (Y, M, C, K) have almost the same settings and the 32 Toner Containers (Y, M, C, K) have almost the same settings except the toner colors used for imaging processes are different. Therefore, explanation only of Toner Replacement Device 60Y and Toner Container 32Y for Yellow, will be made below, and explanation of Toner Replacement Devices 60 (M, C, K) and Toner Containers 32 (M, C) , K) for the other three colors will be omitted accordingly.
[0126] The toner replacement device 60 (Y, M, C, K) is formed of container holding section 70, a drive nozzle 611 (Y, C, K), a drive screw 614 (Y, M, C, K), the toner dump passage 64 (Y, M, C, K), and a container drive section 91 (Y, M, C, K).
[0127] When the 32Y toner container moves in the direction of the arrow Q in figure 4 and attached to the container holding section 70 of the printer 100, the driving nozzle 611 of the 60Y toner replacement device is inserted from the end front of the 32Y toner container together with the setting operation. Consequently, the toner container 32Y and the drive nozzle 611 communicate with each other. A configuration to enable communication along with the clamping operation will be described in detail later.
[0128] As an embodiment of a common toner container of the first through twentieth embodiments, the 32Y toner container is an approximately cylindrical toner container, and essentially includes a container front end cap 34Y that is non-maintained. rotatable through the bowl retaining section 70 and includes bowl body 33Y integrated with a bowl gear 301Y. Container body 33Y is held to pivot relative to container front end cap 34Y.
[0129] The container holding section 70 essentially includes a container lid receiving section 73, a container receiving section 72, and an insertion hole section 71. The container lid receiving section 73 is a section for retaining the 34Y container front end cap of the 32Y toner container. Container receiving section 72 is a section for retaining container body 33Y of toner container 32Y. The insertion hole section 71 forms an insertion hole used in the 32Y toner container clamping operation. When a body cover (not shown) disposed on the front side of the copier 500 (the front side in the normal direction for the sheet of figure 2) is opened, the insertion hole section 71 of the container holding section 70 is exposed. . The clamping/unclamping operation of each of the toner containers 32 (Y, M, C, K) (clamping/unclamping operation with the longitudinal direction of the toner containers 32 taken as a clamping/unclamping direction) is performed at starting from the front side of the copier 500 while each of the 32 toner containers (Y, M, C, K) is oriented with its longitudinal direction made parallel to the horizontal direction. A fitting cap 608Y in Fig. 4 is a part of the container cap receiving section 73 of the container holding section 70.
[0130] The container receiving section 72 is formed such that its longitudinal length is approximately the same as the longitudinal length of the container body 33Y. The container cap receiving section 73 is disposed at a front end of the container receiving section 72 in the longitudinal direction (clamping/unclamping direction) and the insertion hole section 71 is disposed at one end of the receiving section of container 72 in the longitudinal direction. Consequently, along with the operation of attaching the toner container 32Y, the container front end cap 34Y first passes through the insertion hole section 71, slides over the container receiving section 72 for a while, and is finally secured. to container lid receiving section 73.
[0131] When the container drive section 91Y including a drive motor, a drive gear, or the like, introduces rotational drive, to the container gear 301Y provided in the container body 33Y through a container drive gear 601Y, while container front end cap 34Y is attached to container cap receiving section 73, container body 33Y rotates in the direction of arrow A in figure 4. With rotation of container body 33Y, a helical rib 302Y formed in a spiral shape on the inner surface of container body 33Y conducts toner in container body 33Y from left to right in Fig. 4 along the longitudinal direction of container body. Consequently, toner is supplied from the side of the container front end cap 34Y into the drive nozzle 611Y.
[0132] Drive screw 614Y is arranged in drive nipple 611Y. When container drive section 91Y introduces rotation drive to a drive screw gear 605Y, drive screw 614Y rotates and toner supplied in drive nozzle 611Y is driven. The downstream end of the drive nozzle 611Y in the transport direction is fixed to the 64Y toner dump passage, and the toner carried by the 614Y drive screw goes down along the 64Y toner dump passage by gravity and is supplied to the device of development 50Y (the second housing portion of developer 54Y).
[0133] Toner Containers 32 (Y, M, C, K) are replaced with new containers at the end of their life (when the container is empty because almost all the contained toner is consumed). A collet 303 is disposed on an end portion of the toner container 32 opposite the container front end cap 34 in the longitudinal direction. When the toner container 32 is to be replaced, an operator can hold the tweezers 303 to pull out and remove the attached toner container 32.
[0134] A controller 90 calculates, in some cases, a toner consumption amount based on the image information used by the display device 47 described above and determines whether it is necessary to supply the toner to the developing device 50Y. Controller 90 detects, in some cases, a reduction in toner density in the 50Y developer device based on a detection result from the 56y toner density sensor. In these cases, controller 90 rotates container drive section 91Y to rotate container body 33Y of toner container 32Y and drive screw 614Y for a predetermined time to thereby supply toner to developing device 50Y. Since toner is supplied by rotating the 614Y driving screw disposed in the 611Y driving nozzle, it is possible to accurately calculate the amount of toner supply from the 32Y toner container by detecting the frequency of rotation of the driving screw. driving 614Y. If the toner supply amount that has been cumulatively calculated since fixing the 32Y toner container reaches the amount of toner that had been contained in the 32Y toner container at the time of fixing, it is determined that the 32Y toner container is empty of toner and a prompt for replacement of the 32Y toner container is displayed on a screen (not shown) of the copier 500.
[0135] In some cases, even when the 56y toner density sensor detects a decrease in toner density and repeats resetting and determining whether the toner density is recovered, the 56y toner density sensor cannot detect recovery the density of the toner. In this case, the 32Y toner container is determined to be empty of toner and a prompt asking for replacement of the 32Y toner container is displayed on the display (not shown) of the copier 500.
[0136] The common toner replacement device 60Y of the first to the twentieth embodiment controls the amount of toner supplied to the developing device 50Y according to the frequency of rotation of the driving screw 614Y. Therefore, the toner passing through the driving nozzle 611Y is directly transmitted to the developing device 50Y via the toner dumping passage 64Y without controlling the amount of supply toner to the developing device 50Y. Even in the toner reset device 60Y configured to insert the drive nozzle 611Y into the toner container 32Y as described in the present embodiment, it may be possible to supply a temporary storage toner, such as a toner hopper. In this case, the amount of toner supplied to the 50Y developing device can be controlled by controlling the amount of toner transmitted from the toner temporary storage to the 50Y developing device.
[0137] Furthermore, although the 60Y toner replacement device according to the present embodiment uses the 614Y lead screw to transport the toner supplied to the 611Y lead nozzle, the configuration for transporting the toner supplied to the 611Y lead nozzle does not is limited to the screw. It may be possible to apply a carrying force by means of the other screw, for example, using a powder pump to generate a negative pressure in the opening of the drive nozzle 611Y as described in Patent Document 6.
[0138] In the configuration, including toner staging, a toner end sensor is provided to detect whether the amount of toner stored in the toner staging has become a toner staging amount per container body rotation 33Y and drive screw 614Y for a predetermined time based on a toner end detection from the toner end sensor. When the toner end detection of the toner end sensor is not canceled even after the above control is repeated, it is determined that the 32Y toner container is empty of toner and a statement asking for replacement of the 32Y toner container is displayed in the display (not shown) of copier 500. Thus, if the 32Y toner container runs out of toner it is detected based on toner end detection by the toner end sensor, it is not necessary to cumulatively calculate the amount of toner supply from the attachment of the 32Y toner container. However, if temporary toner storage is not provided as in the 60Y toner replacement device according to the present embodiment, it is possible to reduce the size of the 60Y toner replacement device, allowing to reduce the overall size of the copier 500.
[0139] The common toner containers 32 (Y, M, C, K) and toner replacement devices 60 (Y, M, C, K) of the first to twentieth embodiments will be explained in detail below. As described above, Toner Containers 32 (Y, M, C, K) and Toner Replacement Devices 60 (Y, M, C, K) have almost the same settings except that the colors of toner to be used are many different. Therefore, in the following explanation, the Y, M, C, and K symbols representing the toner colors will be omitted.
[0140] Figure 6 is an explanatory perspective view of the common toner container 32 from the first to the twentieth embodiment. Figure 7 is an explanatory perspective view of the toner replacement devices 60 before the toner container 32 is attached and the front end of the toner container 32. Figure 8 is an explanatory perspective view of the toner replacement devices 60 before the toner container 32 is attached and the front end of the toner container 32.
[0141] Figure 1 is an explanatory cross-sectional view of the toner replacement devices 60 before the toner container 32 is attached and the front end of the toner container 32. Figure 9 is an explanatory cross-sectional view of the toner replacement devices 60 to which the toner container 32 is attached and the front end of the toner container 32.
[0142] Toner reset device 60 includes drive nozzle 611 within which drive screw 614 is disposed. The toner reset device 60 further includes a nozzle plug 612. The nozzle plug 612 closes a nozzle opening 610 formed in the drive nozzle 611 at the time of detachment, which is before the toner container 32 is attached. states in Fig. 1 and Fig. 7), and opens the nozzle opening 610, at the time of affixing, which is when the toner container 32 is affixed (in the states in Fig. 8 and Fig. 9). Meanwhile, a receiving opening 331, into which the drive nozzle 611 is inserted at the time of clamping, is formed in the center of the end surface of the toner container 32, and a container shutter 332 is provided which closes the opening of receipt 331 at the time of detachment.
[0143] Toner Container 32 will be explained below.
[0144] As described above, the toner container 32 essentially includes the container body 33 and the container front end cap 34. Figure 10 is an explanatory perspective view of the toner container 32 when the end cap front of container 34 is separate. As illustrated in Figure 10, the toner container 32 from which the container front end cap 34 is detached includes the container body 33 and a nozzle receiver 330 which forms the receiving opening 331.
[0145] Figure 11 is an explanatory perspective view of the toner container 32 when the nozzle receiver 330 is separated from the container body 33. Figure 12 is an explanatory cross-sectional view of the toner container 32 when the nozzle receiver nozzle 330 is separate from container body 33. Fig. 13 is an explanatory cross-sectional view of toner container 32 when nozzle receiver 330 is attached to container body 33 from the state shown in Fig. 12 (end cap front of container 34 is detached from the toner container 32 in a similar manner to Figure 10).
[0146] The container body 33 has the approximate shape of a cylinder and rotates around a central axis of the cylinder as an axis of rotation. Hereinafter, in a direction parallel to the axis of rotation is referred to as "direction of axis of rotation" and a side of the toner container 32, where the receiving opening 331 is formed (the side where the container front end cap 34 is disposed) in the direction of the axis of rotation may be referred to as "a container front end". The front end of the container is also referred to as a first end. In addition, the other side of the toner container 32 where the collet 303 is disposed (the side opposite the front end of the container) may be referred to as "the back end of a container". The rear end of the container is also referred to as a second end. The longitudinal direction of the toner container 32 described above is the direction of the axis of rotation, and the direction of the axis of rotation becomes a horizontal direction when the toner container 32 is attached to the toner replacement device 60. container of the container body 33 with respect to the container gear 301 has an outer diameter greater than that of the front end of the replacement container, and the helical rib 302 is formed on the inner surface of the rear end of the container. When the container body 33 rotates in the direction of arrow A in figure 10, a transport force moves the toner from one end (the rear end of the container) to the other end (the front end of the container) in the direction of the axis of rotation is applied to the toner in the container body 33 due to the action of the helical rib 302.
[0147] Emptying portions 304 are formed on the inner wall of the front end of the container body 33. The emptying portions 304 for collecting the toner, which has been transported to the front end of the container by the helical rib 302 along with rotation of the container body 33 in the direction of arrow A in Figure 10, along with rotation of container body 33. Each of the voiding portions is formed of a convex surface 304h and an voiding wall surface 304f. The convex surface 304h rises within the container body 33 to form a ridge for the center of rotation of the container body 33 in a spiral shape. The emptying wall surface 304f is an inner wall surface which is a part of the wall surface of a growing portion continuing from the convex surface 304h (ridge) to the inner wall of the container body 33 and which is on the downstream side in the direction of rotation of the container. When the void wall surface 304f is located at the bottom, the void wall surface 304f catches the toner, which has been inserted into the void portion 304 by the carrying force of the helical rib 302, along with the rotation of the body. transport 33. Therefore, the toner can be collected and located above the inserted drive nozzle 611.
[0148] As illustrated in Figure 1 and Figure 10, for example, a spiral-shaped voiding portion 304a helical rib is formed on the inner surface of the voiding portion 304 in order to transmit toner into the voiding portion 304 , similar to helical rib 302.
[0149] The container gear 301 is formed at the front end of the container relative to the emptying portion 304 of the container body 33. A gear display hole 34a is disposed on the container front end cap 34 so that a portion of container gear 301 (a far side in Figure 6) may be exposed when container front end cap 34 is attached to container body 33. When toner container 32 is attached to toner reset device 60 , the container gear 301 exposed from the gear display hole 34a is engaged with a container drive gear 601 of the toner reset device 60.
[0150] A cylindrical container opening 33a is formed at the front end of the container relative to the container gear 301 of the container body 33. A nozzle receiver attachment portion 337 of the nozzle receiver 330 is mounted in the cylindrical container opening 33a so that the nozzle receiver 330 can be attached to the container body 33. One method for attaching the nozzle receiver 330 is not limited to snap fit. Other methods including fixing with adhesive agent or fixing with screws may be applied.
[0151] The toner container 32 is configured such that the nozzle receiver 330 is fixed to the cylindrical container opening 33a of the container container body 33 after the container body opening 33 is filled with toner through a front end opening 305.
[0152] A lid hooked portion 306 is formed over cylindrical container opening 33a and is disposed adjacent to container gear 301 of container body 33. Container front end cap 34 is attached to toner container 32 (the container body 33), in the state shown in figure 10 from the front end of the container (from the lower left side in figure 10). Consequently, the container body 33 penetrates through the container front end cap 34 in the direction of the axis of rotation, and a cap hook 341 disposed on the front end portion of the container front end cap 34 is engaged with the hooked portion. of lid 306. The lid hooked portion 306 is formed to enclose the outer surface of the cylindrical container opening 33a, and when the lid hook 341 is engaged, the container body 33 and the container front end cap 34 are fixed to rotate relative to each other.
[0153] The container body 33 is molded by a biaxial stretch blow molding process (see Patent Documents 1 to 3). The biaxial stretch blow molding method generally includes two-stage processes including a preform molding process and a stretch blow molding process. In the preform molding process, a test tube-shaped preform is molded with the resin through injection molding. By injection molding, the cylindrical container opening 33a, the lid hooked portion 306, and the container gear 301 are formed into the opening of the test tube shape. In the stretch blow molding process, the preform which is cooled after the preform molding process and isolated from a mold is heated and softened, and then subjected to stretch blow molding.
[0154] With respect to the container body 33, the rear end of the container with respect to the container gear 301 is molded by stretch blow molding process. Specifically, a portion wherein the void portion 304 and the helical rib 302 are formed and the collet 303 is molded by the stretch blow molding process.
[0155] In the container body 33, each of the parts, such as the container gear 301, the cylindrical container opening 33a and the lid hooked portion 306, at the front end of the container relative to the container gear 301 remains in the same shape as in preform generated by injection molding; therefore, they can be molded with high precision. In contrast, the part where the void portion 304 and the helical rib 302 are formed and the collet 303 is stretch molded by means of the stretch blow molding process after injection molding; therefore, molding accuracy is lower than that of preform molded parts.
[0156] The nozzle receiver 330 attached to the container body 33 will be explained below.
[0157] Figure 14 is an explanatory perspective view of the nozzle receiver 330 seen from the front end of the container. Figure 15 is an explanatory perspective view of the nozzle receiver 330 viewed from the rear end of the container. Figure 16 is a top cross-sectional view of the nozzle receiver 330 viewed from above, in the state shown in Figure 13. Figure 17 is a cross-sectional view of the nozzle receiver 330 viewed from the side (a from the rear side of Figure 13), in the state shown in Figure 13. Figure 18 is an exploded perspective view of the nozzle receiver 330.
[0158] The nozzle receiver 330 includes a container plug holder 340, the container plug 332, a container seal 333, a container plug spring 336, and the nozzle receiver attachment portion 337. The container closure 340 includes a closure rear end support portion 335, closure side support portions 335a, and the nozzle receiver attachment portion 337. The container closure spring 336 is formed by a coil spring. Container plug 332 includes a cylindrical front end portion 332c, a slide section 332d, a guide rod 332e, and first plug hooks 332a. Cylindrical front end portion 332c is a container front end portion that can engage a cylindrical opening (the receiving opening 331) of container seal 333. Slide section 332d is a cylindrical portion which is formed on the side of the rear end of the container relative to the cylindrical front end portion 332c. Slide section 332d has an outer diameter slightly larger than cylindrical front end portion 332c, and slides over the inner surfaces of plug side support portions 335a as a pair. The guide rod 332e is a part of the rod, raised from the inside of the front end cylindrical portion 332c to the rear end of the container and which functions as a guide to prevent the container plug spring 336 from bending upon being bent. inserted into the container closure spring winding 336. The first closure hooks 332a are a pair of hooks, which are provided at the opposite end of the base where the guide rod 332e is configured to prevent the container closure 332 from coming out. of the container plug holder 340.
[0159] As illustrated in Figure 16 and Figure 17, a front end of container shutter spring 336 abuts against the inner wall of cylindrical front end portion 332c, and a rear end of container shutter spring 336 contacts with the wall of the closure rear end support portion 335. This time, the container closure spring 336 is in a compressed state, so that the container closure 332 receives a biasing force in an outward direction. from the plug rear end support portion 335 (to the right or towards the container front end in figure 16 and figure 17). However, the first closure hooks 332a formed on the container rear end of container closure 332 is engaged with an outer wall of closure rear end support portion 335. Consequently, container closure 332 is prevented from moving further in the outwardly from the shutter rear end support portion 335 than in the state illustrated in figure 16 and figure 17. Due to the engaged state between the first shutter hooks 332a and the shutter rear end support portion 335 and the tilting force applied by the container closure spring 336, it is possible to determine the positions of the front end cylindrical portion 332c of the container seal 333, which has a toner leakage prevention function, with respect to the container closure holder 340, in the axial direction. Consequently, it is possible to determine the positions while the cylindrical front end portion 332c and the container seal 333 are mounted, allowing to avoid toner leakage.
[0160] The nozzle receiver attachment portion 337 is in the form of a tube, the outer diameter and inner diameter of which are scaled down to the rear end of the container. Diameters are gradually reduced from the front end of the container to the rear end of the container. Two outer diameter portions (outer surfaces AA and BB from the front end of the container) are formed on the outer surface, and five inner diameter portions (inner surfaces CC, DD, EE, FF, GG and the front of the end container ) are formed on the inner surface. The boundary between outer surfaces AA and BB on the outer surface is connected by a conical surface. Likewise, the boundary between the fourth inner diameter portion FF and the fifth inner diameter portion GG on the inner surface is connected by a conical surface. The inner diameter portion FF on the inner surface and the conical continuous surface correspond to a seal jam prevention space 337b to be described later, and the ridge lines of these surfaces correspond to the cross-sectional sides of a pentagon to be described. later.
[0161] As illustrated in figure 16 to figure 18, a pair of shutter side support portions 335a, which are facing each other and which have flake shapes obtained by cutting a cylinder in the axial direction, are provided so as to projecting from the nozzle receiver attachment portion 337 to the rear end of the container. The rear ends of the two plug rear end support portions 335 are connected to the plug rear end support portion 335 which has a cup shape with an open hole in the center of the bottom. In the two lateral obturator support portions 335a, a cylindrical space SI is formed, which is recognized due to the inner cylindrical surfaces of the abutting lateral obturator support portions 335a and virtual cylindrical surfaces extending from the lateral obturator support portions 335a. The nozzle receiver attachment portion 337 includes the inner diameter portion GG, which is a fifth front end portion, as a cylindrical inner surface having an inner diameter that is the same as the diameter of the cylindrical space SI. The sliding section 332d of the container shutter 332 slides into the cylindrical space SI and the cylindrical inner surface GG. The third inner surface EE of the nozzle receiver attachment portion 337 is a virtual cylindrical surface which passes through longitudinal vertices of equally spaced 45° ribs. The container seal 333 with a square cylindrical (tube-shaped cylindrical) cross section (cross section in the cross-sectional view in Fig. 16 and Fig. 17) is arranged to correspond to the inner surface EE. The container seal 33 is secured to a vertical surface connecting the third inner surface EE and the fourth inner surface FF, with an adhesive agent or double-sided adhesive tape. The exposed surface of the container seal 333 opposite the attachment surface (the right side in Figure 16 and Figure 17) serves as a lower interior portion of the cylindrical opening of the nozzle receiver attachment portion 337 (the container opening).
[0162] As illustrated in Figure 16 and Figure 17, the seal jam prevention space 337b (a retention prevention space) is formed to match the inner surface FF of the nozzle receiver attachment portion 337 and the continuous conical surface. Seal jam prevention space 337b is an annular sealed space closed by three different parts. Specifically, the seal jam prevention space 337b is an annular space enclosed by the inner surface (the fourth inner surface FF and the conical continuous surface) of the nozzle receiver attachment portion 337, the vertical surface of the seal attachment side of container 333, and the continuous outer surface from the cylindrical front end portion 332c to the sliding section 332d of the container shutter 332. A cross section of the annular space (the cross section shown in Figure 16 and Figure 17) has the shape of a pentagon. The angle between the inner surface of the nozzle receiver attachment portion 337 and the end surface of the container seal 333 and the angle between the outer surface of the container plug 332 and the end surface of the container seal 333 is 90°. °.
[0163] The functions of the seal jam prevention space 337b will be described below. When the container plug 332 moves to the rear end of the container while closing the receiving opening 331, the inner surface of the container seal 333 slides against that of the cylindrical front end portion 332c. Consequently, the inner surface of container seal 333 is pulled by container plug 332 and elastically deformed so as to move toward the rear end of the container.
[0164] This time, if the seal jam prevention space 337b is not provided and the vertical surface (the container seal clamping surface 333) held from the third inner surface and the fifth inner surface GG are connected perpendicularly each other, the following situation may occur. Specifically, the elastically deformed portion of the container seal 333 can be trapped between the inner surface of the nozzle receiver attachment portion 337 sliding against the container plug 332 and the outer surface of the container plug 332, which results in causing a jam. If the container seal 333 is wedged in the part where the nozzle receiver attachment portion 337 and the container plug 332 slide against each other, i.e., between the cylindrical front end portion 332c and inner surface GG, the container shutter 332 is firmly fixed to the nozzle receiver attachment portion 337, so that it becomes impossible to open and close the receiving opening 331.
[0165] On the other hand, the seal jam prevention space 337b is formed in the inner area of the nozzle receiver 330 of the present embodiment. The inner diameter of the seal jam prevention space 337b (the inner diameter of each of the inner surface and the continuous tapered surface) is smaller than the outer diameter of the container seal 333. Consequently, the entire container seal 333 can hardly enter the seal jam prevention space 337b. Furthermore, a portion (zone) of container seal 333 to be elastically deformed upon being pulled by container plug 332 is limited, and container seal 333 can be restored by its own elasticity before container seal 333 is brought to and attached to the inner surface GG. With this action, it is possible to avoid a situation where the receiving opening 331 cannot be opened and closed because of the fixed state between the container plug 332 and the nozzle receiver fixing portion 337.
[0166] As illustrated in Figure 16 to Figure 18, a plurality of positioning nozzle plug 337a ribs are formed to extend radially on the inner surface of nozzle receiver attachment portion 337 in contact with the outer circumference of the container seal 333. As illustrated in Figure 16 and Figure 17, when the container seal 333 is secured to the nozzle receiver attachment portion 337, the vertical surface of the container seal 333 at the front of the container protrudes slightly with respect to the front ends of the nozzle positioning obturation ribs 337a in the direction of the axis of rotation. As illustrated in Figure 9, when the toner container 32 is secured to the toner reset device 60, a nozzle plug flange 612a of the nozzle plug 612 of the toner reset device 60 presses down on the protruding portion of the toner seal. container 333 by being protruded by a nozzle plug spring 613. The nozzle plug flange 612a advances and covers the front end surface of the container seal 333 from the side seal opening of the container seal 333 adjoining the front end of the container from the nozzle plug positioning ribs 337a, thus sealing the container from the outside. Therefore, it is possible to ensure the sealing performance in the vicinity of the driving nozzle 611, in the receiving opening 331 at the time of fixing, allowing to avoid toner leakage.
[0167] The rear side of a nozzle plug spring receiving surface 612f of the nozzle plug flange 612a provided by the plug spring 613 abuts against the nozzle plug positioning ribs 337a so that the position of the nozzle shutter 612 with respect to toner container 32 in the direction of the axis of rotation is determined.
[0168] As illustrated in Figure 9, for example, when the toner container 32 is attached to the toner replacement device body 60, the nozzle plug 612 as a contact element and the nozzle plug spring 613 as a guide elements are accommodated in the front end opening 305 which is a cylindrical interior space. To understand the above configuration, the following is an explanation of a relationship between the diameter of the cylindrical outer surface of the cylindrical container opening 33a, the inner diameter of the nozzle receiver attachment portion 337, and the diameters of parts, including a container adjustment section 615 of the toner replacement device 60.
[0169] Figure 66 is an explanatory diagram illustrating a relationship between the diameter of the outer surface of the cylindrical container opening 33a, the inner diameter of the nozzle receiver attachment portion 337, and the diameters of parts including the section of setting container 615 of the toner replacement device 60.
[0170] As will be described later, the container shaping section 615 includes an inner surface 615a of the container shaping section, which is mounted to the outer surface of the toner container 32 when the toner container 32 is mounted in the opening of cylindrical vessel 33a. The inside diameter of the inner surface 615a is designated as D1. The diameter of the outer surface of the toner container 32 of the cylindrical container opening 33a is denoted by d1.
[0171] The nozzle plug 612 provided in the drive nozzle 611 includes the nozzle plug flange 612a, and the outside diameter of the nozzle plug flange 612a is designated as D2. The inside diameter of the nozzle receiver attachment portion 337 on the outer side, relative to the container seal 333 in the axial direction (the inside diameter of the second inner surface from the front end of the container) between the inside diameters of the container attachment portion. nozzle receiver 337 is denoted by D2, and the outside diameter of the container seal 333 is denoted by D3. The plug nozzle positioning ribs 337a come into contact with the outer surface of the container seal 333 and are disposed between the outer surface of the container seal 333 and the second inner surface of the nozzle receiver attachment portion 337 of the front end . The outer diameter of the nozzle plug 612 (the outer diameter of a nozzle plug tube 612 to be described later) is designated as D3, and the inner diameter of the container seal 333 is designated as d2.
[0172] When the toner container 32 is secured, the drive nozzle 611 enters the receiving opening 331 when the nozzle opening 610 is closed by the nozzle plug 612. The nozzle plug flange 612a contacts the seal of container 333 and subsequently presses the container seal 333 low. Thereafter, the nozzle plug flange 612a abuts against the front ends of the nozzle plug position ribs 337a so that the nozzle opening 610 is open and the interior of the toner container 32 and the interior of the drive nozzle 611 become communicate with each other. This time, the outer surface of the toner container 32 and the inner surface 615a of the container shaping section of the cylindrical container opening 33a are fitted together, and the container body 33 is rotatably placed in the fitted position.
[0173] To rotatably engage the outer surface of the cylindrical container opening 33a of the toner container 32 and the inner surface 615a of the container configuration section, a diameter d1 of the outer surface of the toner container 32, the cylindrical container opening 33a and the inner diameter D1 of the inner surface 615a of the container configuration section are defined such that "d1 <D1". Also, d1 and D1 are set so that a fit tolerance becomes 0.01mm to 0.1mm. By maintaining the relationship “d1 <D1”, it is possible to rotate the bowl body 33, holding it to the bowl setting section 615.
[0174] The drive nozzle 611 and the nozzle plug 612 are configured such that they enter the receiving opening 331 while the opening 610 of the nozzle of the driving nozzle 611 is closed by the nozzle plug 612. , the outer diameter D2 of the nozzle plug flange 612a and the inner diameter d2 of the nozzle receiver attachment portion 337 on the outer side, relative to the container seal 333 in the axial direction (the inner diameter of the second DD inner surface from of the front end of the container) between the inner diameters of the nozzle receiver attachment portion 337 are configured such that "D2 < d2".
[0175] To make the nozzle plug flange 612a contact and press down the vessel seal 333 and thereafter lean against the front ends of the nozzle plug positioning ribs 337a, the outer diameter D2 of the 612a nozzle plug flange is fixed such that “D2 > d3”. Specifically, a ratio of "D3 <D2 <d2" is defined between the outer diameter D2 of the nozzle plug flange 612a, the inner diameter d2 of the nozzle receiver attachment portion 337 on the outer side, relative to the container seal 333 in the direction of the axis direction between its inner diameters and the outer diameter D3 of the container seal 333.
[0176] With the above configuration, it becomes possible to accommodate the nozzle plug 612 in the opening of the front end 305 of the toner container 32 (inside the nozzle receiver fixing portion 337). Although the container seal 333 and the nozzle plug flange 612a slide against each other along with the rotation of the container body 33, it is possible to prevent damage to the container seal 333 due to slippage. This is because the nozzle plug flange 612a contacts the positioning plug ribs of the 337a so as not to overly press the container seal 333 down and it is possible to suppress a sliding load. Furthermore, because the flange of the nozzle plug 612a moderately engages the container seal 333 by pressing the container seal 333 downwards, it is possible to decrease the toner dispersion that may occur when attaching the toner container 32.
[0177] In addition, the outside diameter D3 of the nozzle plug 612 and the inside diameter D4 of the container seal 333 the nozzle receiver 330 are configured such that "d4 <D3". With this configuration, the inside diameter of the container seal 333 is stretched together with the insert of the driving nozzle 611, so that the container seal 333 can properly fit the nozzle plug 612. Therefore, it is possible to avoid toner leakage. from the toner container 32 to the outside while the drive nozzle 611 is inserted.
[0178] To put all of the above ratios together, each of the parts of the toner container 32 is defined such that a ratio of “d4 <D3 <D3 <D2 <D2 <d1 <D1” to the diameters can be obtained. With this definition, it is possible to realize both the sealing ability to prevent dispersion or leakage of toner from the toner container 32 and the housing capacity for the nozzle plug housing 612 and the nozzle plug spring 613.
[0179] As will be described later, when the toner container 32 is attached, the nozzle opening 610 is opened after the nozzle plug flange 612a abuts against the nozzle plug positioning ribs 337a and the position of the nozzle plug. nozzle 612 with respect to toner container 32 is fixed. On the other hand, when the toner container 32 is individual, even after the drive nozzle 611 starts to be removed from the toner container 32, the position of the nozzle shutter 612 with respect to the toner container 32 does not change due to biasing force of the nozzle plug spring 613 while the nozzle opening 610 is opened.
[0180] When the toner container 32 is pulled out, the position of the toner container 32 with respect to the drive nozzle 611 changes, so that the position of the nozzle shutter 612 with respect to the drive nozzle 611 also changes. Consequently, the nozzle plug 612 begins to close the nozzle opening 610. This time, the distance between the toner container 32 and the container adjustment section 615 becomes longer, along with the toner container extraction operation. toner 32. In this way, the nozzle plug spring 613 extends to its natural length, due to its own reset force, so that the thrust force applied to the nozzle plug 612 is reduced.
[0181] When the toner container 32 is pulled further away from the nozzle plug 612 completely closes the nozzle opening 610, a portion of the nozzle plug 612 (in particular, "a first inner rib 612b", to be described later) touches against a part of the drive nozzle 611. With this contact end, the position of the nozzle plug 612 relative to the drive nozzle 611 is fixed, and the contact of the nozzle plug end 612 with the ribs of positioning of the nozzle plug 337a is released.
[0182] Thereafter, the toner container 32 is pulled further out, so that the nozzle plug 612 is removed from the toner container 32, together with the driving nozzle 611.
[0183] When the nozzle plug flange 612a is in contact with the nozzle plug positioning ribs 337a, a portion where the nozzle opening 610 is formed in the drive nozzle 611 is entirely within the toner container 32 with respect to an inlet of the receiving opening 331. Specifically, the nozzle opening is located opposite the emptying portion 304, where the nozzle opening 331 passes through the container gear 301 in the direction of the axis of rotation. Since the nozzle opening 610 is open, while being fully inside the toner container 32, it is possible to prevent toner leakage from the nozzle opening 610 to the outside.
[0184] The side shutter support portions 335a and 335b of a space between the side support portions, which is like an opening disposed adjacent the side support portion are formed such that the side shutter support portions 335a are facing to each other they form a part of a cylindrical shape and another part of the cylindrical shape is cut into two portions 335b of the space between the lateral support portions. With this shape, it is possible to guide the container plug 332 to move in the direction of the axis of rotation in the SI cylindrical space formed within the cylindrical shape.
[0185] The nozzle receiver 330 attached to the container body 33 rotates together with the container body 33 when the container body 33 rotates. This time, the shutter side support portions 335a of the nozzle receiver 330 rotate around the drive nozzle 611 of the toner replacement device 60. Therefore, the shutter side support portions 335a being rotated pass through a space immediately above of the nozzle opening 610 formed at the top of the drive nozzle 611. Consequently, even when toner is instantly accumulated above the nozzle opening 610, as the shutter side support portions 335a traverse the accumulated toner and alleviate the accumulation, it is It is possible to avoid a situation where accumulated toner is aggregated in the sleep state, and a toner conductor failure occurs when the device is resumed. On the other hand, when the shutter side support portions 335a are located on the driving nozzle side 611 and the nozzle opening 610 and the space 335b between the face portions support side each other, the toner in the container body 33 is supplied to the drive nozzle 611 as indicated by an arrow in figure β . 9.
[0186] As illustrated in Figure 16 and Figure 17, a step that is between the first outer surface AA and the second outer surface BB is formed such that the outer diameter of the nozzle receiver attachment portion 337 at the rear end of the container is reduced in the middle of the outer surface of the nozzle receiver attachment portion 337 in the direction of the axis of rotation. As illustrated in Figure 13, the inner surface of the cylindrical container opening container body 33a 33a is shaped so as to follow the outer surface of the nozzle receiver attachment portion 337, and a step is formed such that the diameter interior of the cylindrical container opening 33a of the rear end of the container is reduced. The step on the outer surface of the nozzle receiver attachment portion 337 abuts against a step on the inner surface of the cylindrical container opening 33a throughout in the circumferential direction. Therefore, it is possible to prevent the axis of the nozzle receiver 330 from being inclined relative to the container body 33 (a state where the central axis of the nozzle receiver attachment portion 337 is inclined relative to the central axis of the container opening cylindrical 33a). Second Implementation
[0187] A toner container 32 according to a second embodiment will be explained below, wherein the container shutter 332 is modified compared to the toner container 32 of the first embodiment.
[0188] The toner container 32 can be taken from the copier 500 in the state illustrated in figure 6. However, when the toner container 32 alone is transported or is set to the main body by a user, the toner container 32 can be discarded.
[0189] Figure 19 is an explanatory diagram illustrating a state where the toner container 32 falls with the rear end facing downwards. An arrow 51 in figure 19 indicates the direction of the fall.
[0190] If the toner container 32 falls and hits the ground as illustrated in figure 19, the inertial force of the container shutter 332 acts in the same direction as the falling direction, as indicated by an arrow 52 in figure 19. The inertial force increases as the impact due to the fall increases, and if the inertial force becomes greater than the pressing force of the canister plug spring 336, the canister plug 332 moves in the direction in which the force acts inertia (at arrow 52, direction in figure 19). In this case, if the movement amount of container plug 332 becomes greater than the thickness of container seal 333, a difference is generated between container plug 332 and container seal 333 for a moment and toner can be spread. In addition, if the container body 33 of the toner container 32 is a hollow resin product formed by blow molding, the impact due to such hitting can be turned into motion and the inertial force can be increased.
[0191] To reduce the amount of movement of the container closure 332 caused by the inertial force due to the fall, it is effective to use the container closure spring 336 with a greater pressure force. However, if the pressing force of container closure spring 336 is increased, an adverse effect as described below occurs.
[0192] Specifically, if the pressing force of the container plug spring 336 is increased, a contact pressure between the container plug 332 and the driving nozzle 611 is increased, while the toner container 32 is fixed to the reset toner 60. If contact pressure increases, drive torque to rotate toner container 32 increases. Consequently, a 603 drive motor with a higher output is needed and the cost of 603 drive motors increases. In addition, with an increase in contact pressure, abrasion of the contact surfaces of container plug 332 and drive nozzle 611 increases resulting in lesser durability.
[0193] Furthermore, if the pressing force of the container shutter spring 336 increases, a greater force is required to set the toner container 32 at the toner reset device 60 resulting in reduced operability. In addition, the pressing force of the container shutter spring 336 acts in the direction that the toner container 32 is pushed out of the toner reset device 60. In this way, the pressing force of the container shutter spring 336 increases, there is a risk that the toner container 32 may spring out of the toner reset device 60 immediately after a state engaged between the frames (reset device engaging member 609 and the container engaging portion 339) to engaging the toner container 32 with the toner reset device 60 is released.
[0194] Figure 20 and Figure 21 are explanatory diagrams illustrating a configuration in which the second obturation hooks 332b are provided in a position slightly closer to the front end of the container shutter container 332 in relation to the guide rod 332e of the first shutter hooks 332a. Figure 20 is an explanatory cross-sectional view of the toner reset device 60 before the toner container 32 is attached and the front end of the toner container 32. Figure 21 is an explanatory cross-sectional view of the reset device of toner container 60 to which the toner container 32 is attached and the front end of the toner container 32.
[0195] In the configuration illustrated in Figure 20 and Figure 21, the container shutter 332 of the toner container 32 is pressed in the direction that the receiving opening 331 is closed by the container shutter spring 336 (to the left in Figure 20 ). Container closure 332 includes a pair of first closure hooks 332a and a pair of second closure hooks 332b, such as two pairs of hooks configured to prevent container closure 332 from protruding, at the rear end of the container with respect to the stem. tab 332e.
[0196] The rear end of the guide rod container 332e is bifurcated, so as to form a pair of cantilevered pieces 332f. The first shutter hooks 332a and the cantilever parts of the second shutter hooks 332b are disposed on the respective outer surfaces of the beams. As illustrated in Figure 20, the vertical surface of the plug rear end support portion 335 is located between the first plug hooks 332a and the second plug hooks 332b when the container plug 332 closes the receiving opening 331. smaller than the projected area of the first plug hooks 332a in the axial direction is formed on the vertical surface of the plug rear end support portion 335. The guide rod 332e is inserted into the can plug spring 336 and the pair of pieces cantilever 332f of guide rod 332e is bent towards the center of the axis of guide rod 332e so as to pass first plug hooks 332a through the hole in the vertical surface of plug rear end support portion 335. Guide rod 332e is mounted over container body 33 as illustrated in Figure 20. Guide rod 332e is molded with resin such as polystyrene. reno so as to ensure the elasticity that allows the cantilever parts 332f to flex.
[0197] Figure 20 illustrates a state before the toner container 32 is situated in the main body of the toner replacement device 60 (unused) when, for example, the toner container 32 is transported.
[0198] When the toner container 32 is located in the main body of the toner reset device 60 in the state shown in figure 20, the toner container 32 is pushed into the main body and the front end of the drive nozzle 611 pushes the container shutter 332 into the toner container 32. At this time, the first stopper hooks 332a at the end of guide rod 332e are pushed out of the container rear end of the shutter rear end support portion 335. Consequently , the second plug 332b hooks which are second hooks engaged with the hole in the vertical surface of the plug rear end support portion 335.
[0199] The hole in the vertical surface is smaller than the projected area of the second obturator hooks 332b, and consequently, the second obturator hooks 332b do not come out when in contact with the vertical surface. However, when the user increases the thrust force applied to the toner container 32, the thrust force acts on the contact point of the second hook 332b of the shutter and the vertical surface. Due to the action of the pushing force, both the second shutter hook 332b and the pair of overhanging pieces 332f provided on the outer surface are bent towards the center of the guide rod axis 332e, so that the second shutter hook 332b passes through. of the hole on the vertical surface. Accordingly, as illustrated in Fig. 21, second closure hooks 332b are located within toner container 32 relative to closure rear end support portion 335.
[0200] Since the container shutter 332 is set on the toner container 32, the second stopper hooks 332b have the function to prevent the container shutter 332 from coming out.
[0201] As described above, when the toner container 32 alone is carried or is set in the main body by a user, the toner container 32 can be discarded. In this case, as explained above with reference to Figure 19, a force in the opening direction of the container shutter 332 can be applied to the container shutter 332, due to the inertial force of the container shutter 332. However, if the seconds shutter hooks 332b are provided as in the configuration illustrated in figure 20 and figure 21, it is possible to avoid scattering of toner when the toner container 32 falls for reasons described below. Specifically, when container closure 332 is forced to move in the opening direction, the biasing force of container closure spring 336 is a force necessary to pass second closure hooks 332b through the orifice (i.e., a bending force for the pair of rocker pieces 332f) preventing the container plug 332 from moving in the opening direction. Since the inertial force due to the impact on the fall time does not increase contrary to the thrust force applied by the user, the second plug hooks 332b are engaged with the hole in the vertical surface of the plug rear end support portion 335 and container plug 332 can be prevented from opening. Therefore, it is possible to avoid scattering of toner when the toner container 32 falls.
[0202] In the toner container 32 configured as illustrated in figure 20 and figure 21, it is possible to prevent the shutter movement when the toner container falls, without increasing the pressure force of the container shutter spring 336. Therefore it is possible to prevent scattering the toner at the time of the drop without causing the adverse effect described above. Furthermore, only the second plug 332b hooks are added to the container plug 332 compared to the configuration explained above with reference to Figure 1 and Figure 9, for example, and additional parts are not necessary. As a result, it is possible to prevent toner from scattering at drop time at low costs.
[0203] The configuration of the common container front end cap 34 of the first to twentieth embodiments will be explained below with reference to figure 5 to figure 8.
[0204] The container front end cap 34 of the toner container 32 is caused to slide and move over the container receiving section 72 illustrated in Figure 5 at the time of attachment to the toner replacement device 60. In Fig 5, continuous troughs from the insertion hole section 71 of the container cap receiving section 73 are formed just below the four toner containers 32, respectively, such that the longitudinal side passes along the axial direction of the container body 33. Sliding guides 361 as a pair are formed on both undersides of container front end cap 34 so as to allow container front end cap 34 to slide and move while sliding guides 361 are coupled with the gutter. More specifically, the slide rails as a pair protrude on both sides of each of the rails of the container receiving section 72. Slide rails 361A parallel to the axis of rotation of the container body 33 are formed in the slide guides 361, a order to press the pair of slide rails from above and below. In addition, container front end cap 34 includes container engaging portion 339 which is engaged with reset device engaging member 609 on adjustment cap 608 at the time of attachment to toner reset device 60.
[0205] The container front end cap 34 also includes an identification tag (identification chip) 700 for recording data such as the use of the toner container 32. The container front end cap 34 also includes a rib 34b of a specific color which prevents the toner container 32 containing toner of a certain color from being applied to the cap 608 of configuration of a different color. As described above, as the slide guides 361 are coupled with the slide rails of the container receiving section 72 at the time of attachment, the posture of the container front end cap 34 on the toner reset device 60 is determined. . Accordingly, the positioning between the container engaging portion 339 and the reset device engaging member 609 and the positioning between the identification tag 700 and a connector 800 to be described later can be accomplished without problems.
[0206] The common toner replacement device 60 of the first through twentieth embodiments will be explained below.
[0207] As illustrated in Figure 7 and Figure 8, the toner replacement device 60 includes a nozzle holder 607 that secures the drive nozzle 611 to a frame 602 of the main body of the copier 500. The cover configuration 608 is secured. to the nozzle holder 607. The toner discharge passage 64, which is arranged to communicate with the interior of the lead nozzle 611 from the bottom of the lead nozzle 611, is secured to the nozzle holder 607.
[0208] The toner discharge passage 64 may include, as in the configuration illustrated in Figure 20 and Figure 21, an oscillating spring 640 therein.
[0209] One end of the wobble spring 640 is coupled with the shaft of the carrier screw 614 of rotation, and moves in the vertical direction along with the rotation of the drive screw 614. The wobble spring 640 scrapes toner stagnant or attached to the vicinity of the interior surface of the toner discharge passage 64 which serves as a tube element, together with the vertical movement. To improve the effect of preventing clogging of the toner discharge passage 64, it is desirable to place the wobble spring 640 configured to swing closer to the inner surface of the toner discharge passage 64. In the configuration of the embodiment, as the passage The Toner Dump Pass 64 is a cylindrical component, the oscillating spring 640 (a spring with a diameter slightly smaller than the diameter of the inner wall of the Toner Dumping passage 64) is used as an oscillating scraper. However, it is preferable to adjust the shape of the oscillating scraper according to the shape of the cross section of the toner drop passage 64 such that when the shape of the X section of the toner drop passage 64 is other than a circle, the shape of the oscillating scraper is adjusted in accordance with the actual shape.
[0210] In addition, the container drive section section 91 is fixed to the frame 602.
[0211] The container drive section 91 is fixed to the frame 602. The container drive section 91 includes the drive motor 603, the container drive gear 601, and a helical gear 603a for the motor drive transmission drive 603 for rotation of the rotation shaft of the container drive gear 601. A gear transmission unit 604 is fixed to the rotation axis of the container drive gear 601 so as to be engaged with the drive screw gear 605 fixed to the shaft of the drive screw 614. With this rotation configuration, it is possible to rotate the toner container 32 through the container drive gear 601 and the container gear 301. In addition, it is possible to rotate the toner container screw driving 614 through the gear transmission unit 604 and the screw conveyor gear 605, together with the rotation of the toner container 32.
[0212] It may be possible to provide a clutch in the one-pass transmission unit from the drive motor 603 to the container gear 301 or in a transmission unit from the drive motor 603 to the transport screw gear 605 . With the clutch, it becomes possible to turn only one of the toner container 32 and the driving screw 614 along with the rotation of the drive motor 603.
[0213] The drive nozzle 611 of the toner reset device 60 will be explained below.

Figure 23 is an explanatory perspective view of the nozzle plug 612 seen from a side where the toner container 32 is attached ( a front end of the nozzle).

Fig. 28 is an explanatory perspective view of the vicinity of the nozzle opening 610 when the nozzle plug 612 is detached. In Fig. 25, Fig. 26, and Fig. 28, the drive screw 614 disposed within the drive nozzle 611 is omitted.
[0215] At the base end of the driving nozzle 611, the container configuration section 615 is formed, wherein the cylindrical container opening 33a is mounted when the toner container 32 is attached to the toner reset device 60. container mounting bracket 615 is in the form of a cylinder and is mounted such that the inner surface 615a thereof and a cylindrical outer surface of the cylindrical container opening 33a can slide against each other. With this fitting, the position of the toner container 32 relative to the toner replacement device 60 in the planar direction perpendicular to the axis of the toner container 32 rotation is determined. When the toner container 32 rotates, the outer surface, the cylindrical container opening 33a functions as a rotating shaft section and the container adjustment section 615 functions as a receiving section shaft. The position at which the cylindrical outer surface of the cylindrical container opening 33a and the container adjusting section 615 slidingly contact each other and the positioning of the toner container 32 relative to the toner reset device 60 is determined as indicated by α in figure 9.
[0216] As illustrated in Fig. 22 For example, the nozzle plug 612 includes the nozzle plug flange 612a and the nozzle plug tube 612e. The first inner rib 612b is formed in a portion of the upper inner surface of the nozzle plug tube 612e, near the front end of the nozzle. A second inner rib 612c and a third inner rib 612d are formed on the inner surface of the tube 612e obturator nozzle, near the base end of the nozzle to enclose the inner surface.
[0217] The length of the first inner rib 612b in the circumferential direction on the inner surface is adjusted so that the first inner rib 612b can be mounted in the width of the nozzle opening 610 in the circumferential direction, while the nozzle plug 612 is fixed to the driving nozzle 611.
[0218] As illustrated in Figure 1 and Figure 25, the end of the nozzle plug spring 613 at the nozzle base end abuts against an end surface 615b of the container configuration section 615. of the nozzle plug 613 at the front end of the nozzle ends abuts against the nozzle plug spring of the receiving surface 612f of the nozzle plug flange 612a. This time, the nozzle plug spring 613 is in a compressed state and a bias force is applied to the nozzle plug 612, in a direction where the nozzle plug 612 comes out of the front end of the nozzle (to the left in figure 25). However, the first inner rib tips 612b against the edge of the nozzle opening 610 at the front end of the nozzle, i.e., the upper inner surface of a front end 611a of the drive nozzle 611. Consequently, the nozzle plug 612 is impeded to move in a direction where it exits the drive nozzle 611 in the state shown in figure 25 or figure 26. Due to the contact end of the first inner rib 612b and the biasing force of the nozzle plug spring 613, the position of the nozzle plug 612 relative to the driving nozzle 611 in the direction of the axis of rotation is determined.
[0219] A front end 612g of the first inner rib, which is an end of the first inner rib 612b in the circumferential direction, is shaped in such a way that it can hit against a rim nozzle opening 611s, which is an edge of the nozzle opening 610 in the lateral direction. Specifically, the front end 612g of the first inner rib is shaped so as to butt against the rim nozzle opening 611s when the nozzle plug 612 is forced to rotate in the direction of arrow A in Fig. 26.
[0220] When the toner container 32 rotates, a force causing rotation in the direction of arrow A in figure 26 acts on the nozzle plug 612, where the outer surface of the tube 612e plug nozzle contacts the inner surface of the container seal 333 affixed to the toner container 32. This time, if the nozzle plug 612 rotates relative to the drive nozzle 611 and the first inner rib 612b is separated from the nozzle opening 610, the following can occur. Specifically, the nozzle plug 612 may come out of the driving nozzle 611 due to the pressing force based on the resetting of the action of the nozzle plug spring 613 when the toner container 32 is detached from the toner reset device 60 .
[0221] Furthermore, depending on the elasticity of the nozzle plug 612, the first inner rib 612b separated from the nozzle opening 610 can firmly grip the outer surface of the drive nozzle 611 and the nozzle plug 612 is prevented from moving relative to drive nozzle 611. In each case, nozzle opening 610 remains open when toner container 32 is detached from toner replacement device 60, resulting in toner leakage.
[0222] In contrast, in the toner replacement device 60 according to the present embodiment, when the nozzle plug 612 is forced to rotate in the direction of arrow A in Figure 26, the front end 612g of the first inner rib tips against the 611s nozzle opening of the rim. Consequently, it is possible to prevent the nozzle plug 612 from rotating relative to the driving nozzle 611 in the state shown in Fig. 26.
[0223] The inner diameters of the second inner rib 612c and the third inner rib 612d are configured to be slightly smaller than the outer diameter of the cylindrical drive nozzle 611. The second inner rib 612c and the third inner rib 612d, which are molded with resin, are elastically deformed so that the nozzle plug 612 can be connected to the drive nozzle 611. Like the two ribs (612C, 612d) with the diameters internals slightly smaller than the outer diameter of the drive nozzle 611 are elastically deformed and come into contact with the outer surface of the drive nozzle 611, the sealing performance between the inner surface of the nozzle plug 612 and the outer surface of the nozzle 611 driving can be improved. Therefore, it is possible to prevent toner leakage from a gap between the nozzle plug 612 and the driving nozzle 611.
[0224] The toner replacement device 60 according to the present embodiment uses a conical spring as the nozzle plug spring 613. The conical spring allows at least a portion of adjacent coils to overlap each other in the fully compressed state , so that the length in the direction of the winding shaft in the fully compressed state can be reduced compared to a cylindrical spring with the same length as the spring. Therefore, it is possible to reduce a nozzle plug spring space 613 in the direction of the winding axis in the fully compressed state.
[0225] A process for attaching the toner container 32 to the toner replacement device 60 will be explained below.
[0226] When the toner container 32 is moved towards the toner replacement device 60, as indicated by an arrow in figure Q. 7 or figure 1, the front end 611a of the drive nozzle 611 contacts the surface of the front end surface of the container shutter 332. When the toner container 32 is further moved to the toner reset device 60, the driving nozzle 611 presses the front end surface of the container shutter 332. container 332, the container shutter spring 336 is compressed. Consequently, the container plug 332 is pushed into (to the rear end of the container) the toner container 32 along with the compression and the front end of the drive nozzle 611 is inserted into that receiving opening 331. This time , a portion of the nozzle plug tube 612e at the front end of the nozzle relative to the nozzle plug flange 612a of the nozzle plug 612 is also inserted into the receiving opening 331 together with the driving nozzle 611.
[0227] When the toner container 32 is further moved to the toner replacement device 60, the opposite surface a nozzle plug spring receiving surface of the nozzle plug flange 612a contacts the front end surface of the seal of container 333. Subsequently, the surface contacts the nozzle plug positioning ribs 337a by lightly pressing the container seal 333. Consequently, the position of the nozzle plug 612 with respect to the toner container 32 in the direction of the axis of rotation is fixed.
[0228] When the toner container 32 is further moved to the toner reset device 60, the drive nozzle 611 is inserted further into the toner container 32. This time, the nozzle plug 612 abuts against the nozzle positioning closure ribs 337a is pushed back to the base end of the drive nozzle 611. Consequently, the nozzle plug spring 613 is compressed and the relative position of the nozzle plug 612 and the guide nozzle 611 are moved to the end of the base of the mouthpiece. Due to the change of relative position, the nozzle opening 610 covered by the nozzle plug 612 is exposed within the container body 33 and the interior of the container body 33 and the interior of the drive nozzle 611 communicate with each other.
[0229] When the drive nozzle 611 is inserted into the receiving opening 331, a force in a direction that the toner container 32 is pushed back relative to the toner reset device 60 (in a direction opposite to that of the arrow Q in figure 7) acts due to the pressing force of the compressed container plug spring 336 or the nozzle plug spring 613. However, when the toner container 32 is attached to the toner reset device 60, the toner container 32 is moved to a position in which the container engaging portion 339 is engaged with the resetting device engaging member 609 in a direction of the toner resetting device 60 against the aforementioned force. Therefore, the biasing force of the container closure spring 336 and the nozzle closure spring 613 and the engaged state between the container engaged portion 339 and the reset device engaging member 609 becomes active. Due to the action of the pressing force and the engaged state, the position of the toner container 32 with respect to the toner replacement device 60 in the direction of the axis of rotation is determined in the state shown in figure 8 and figure 9.
[0230] As illustrated in Figure 7, each of the engaging container portions 339 includes a guide boss 339a, a guide rail 339b, a shoulder 339c, and an engaged rectangular hole 339d. Two sets of engaging container portions 339 each including, as a set, the above portions disposed on both sides of container front end cap 34 in a symmetrical shape with respect to a vertical line passing through the receiving opening 331 Guide protrusions 339a are disposed on a vertical front surface of container front end cap 34 so as to be in the horizontal line passing through the center of receiving opening 331. Guiding protrusions 339a include sloping surfaces leading to the chutes of guide 339b. The angled surfaces contact the replacement device engaging member 609 and guide the replacement device engaging member 609 to the guide rails 339b at the time of securing the toner container 32. The guide rails 339b are chutes which are sunk into the side of the container front end cap 34.
[0231] The widths of the guide rails 339b are adjusted to be slightly wider than the reset device engaging member 609 and to be suitable for preventing the reset device engaging member 609 from coming out of the rails.
[0232] The rear ends of the 339b guide rails are not continued directly to the engaged holes 339d, but are terminated. The heights of the guide rails 339b are the same as the height of the side surface of the container front end cap 34. Specifically, outer surfaces with widths of approximately 1 mm are present between guide rails 339b and which engaged holes 339d, which correspond to lugs 339c.
[0233] Replacement device engagement member 609 rises on lugs 339c and falls into engaged holes 339d. As a result, the toner container 32 and the toner replacement device 60 are coupled together.
[0234] The toner container 32 is configured such that the container shutter 332 is located at the center of a straight segment connecting the two engaged portions of container 339 in a virtual plane perpendicular to the axis of rotation. If the container plug 332 is not located on the line segment connecting the two engaged container portions 339, the following may occur. Specifically, at a distance from the straight segment to the container shutter 332 becomes a lever and moment of force that rotates the toner container 32 about the line segment is generated due to the pressure force between the spring of the container shutter 336 between nozzle shutter spring 613 in position of container shutter 332. Due to the action of moment, toner container 32 may be tilted relative to toner reset device 60. In this case, a clamping charge of the toner container 32 increases, increasing the load on the nozzle receiver 330 which holds and orients the container shutter 332.
[0235] In particular, if the toner container 32 is new and properly filled with toner, and when the toner container 32 is pushed from the rear end in such a way that the driving nozzle 611 is inserted in the horizontal direction, moment of force acts to rotate the toner container 32 due to the weight of the toner container 32 with the added weight. Consequently, a load is applied to the nozzle receiver 330 into which the drive nozzle 611 is inserted, and the nozzle receiver 330 can be damaged or broken in the worst case. On the other hand, in the toner container 32 according to the present embodiment, because the container shutter 332 is located on the straight segment connecting the engaged container portions 339 required. Consequently, it is possible to prevent the toner container 32 from being tilted relative to the toner reset device 60, due to the pressing force of the container shutter spring 336 and the nozzle shutter spring 613 acting in the position of the container 332.
[0236] As illustrated in Figure 31B, the circular end surface of the cylindrical container opening 33a of the toner container 32 does not contact the end surface 615b of the container adjustment section 615 when the toner container 32 is attached to the device. Replacement Toner 60. The reason for this is as follows. It is assumed that the cylindrical circular end surface of the cylindrical container opening 33a contacts the end surface 615b of the container fitting section 615. In this configuration, the circular end surface of the cylindrical container opening 33a may abut against to the end surface 615b of the container fitting section 615 before the engaged holes 339d of the container engaging portions 339 are engaged with the reset device engaging member 609. If the end ends surfaces against each other as described above, it is impossible to move the toner container 32 further away from the toner reset device 60, so positioning on the axis of rotation becomes impossible. To avoid such a situation, when the toner container 32 is attached to the toner reset device 60, a small difference is generated between the circular end surface of the cylindrical container opening 33a and the end surface 615b of the container forming section. 615.
[0237] When the position in the direction of the axis of rotation is determined as described above, the outer surface of the cylindrical portion of the cylindrical container opening 33a is rotatable and mounted on the inner surface 615a of the container configuration section 615. Consequently, as described above, the position of the toner container 32 with respect to the toner replacement device 60 penetrating in the planar direction perpendicular to the axis of rotation is determined. Consequently, the attachment of the toner container 32 to the toner replacement device 60 is completed.
[0238] When the toner container 32 is fully secured, if the drive motor 603 is rotated, the container body 33 of the toner container 32 and the drive screw 614 inside the drive nozzle 611 rotate.
[0239] With the rotation of the container body 33, the toner in the container body 33 is transported to the front end of the container of the container body 33 by the helical rib 302. The toner reaching the emptying portion 304 by the transport is withdrawn until it is located above the nozzle opening 610 by the emptying portion 304, together with the rotation of the container body 33. The collected toner to be placed above the nozzle opening 610 falls to the nozzle opening 610, so that toner is supplied to drive nozzle 611. Toner supplied to drive nozzle 611 is conveyed by drive screw 614 and is fed to toner developing device 50 through toner dump passage 64. Toner flow from from the inside of the container body 33 to the toner discharge passage 64 at this time is indicated by an arrow β in figure 9. Third Achievement
[0240] A modification of rotation timings of the toner container 32, etc. according to a third embodiment will be explained.
[0241] In the configurations explained above in the first and second embodiments, the toner container 32 and the driving screw 614 are rotated simultaneously. However, with respect to rotation timings, it may be possible to rotate only the toner container 32 at the beginning of toner replenishment and subsequently to rotate the driving screw 614 after a predetermined time interval has elapsed. Furthermore, it may be possible to stop the toner container 32 at the end of the toner replenishment, and subsequently stop the drive screw 614 after a predetermined time interval has elapsed. A timing map of previous rotation intervals is illustrated in Figure 29.
[0242] In the configuration with the rotation timings illustrated in Fig. 29, when toner replenishment is stopped, the rotation of the toner container 32 is stopped before the rotation of drive screw 614 inside drive nozzle 611 is stopped. With these rotation timings, transport by the drive screw 614 is continued at the nozzle opening 610 while the supply of new toner is stopped, and rotation of the drive screw 614 is subsequently stopped after a predetermined time has elapsed. Therefore, toner T that remains in the vicinity of the nozzle opening 610 of the drive nozzle 611 when the rotation of the toner container 32 is stopped can be transmitted to the toner dump passage 64 via the drive screw 614. -it is possible to reduce the amount of toner remaining T in the drive nozzle 611, near the nozzle opening 610. When the toner container 32 is separated from the main body of the toner reset device, such as the amount of toner on the nozzle lead 611 has been reduced, the container seal 333 arranged on the nozzle receiver 330 can easily clean the lead nozzle 611. Consequently, it is possible to prevent scattering and toner drop due to attachment/separation of the toner container 32 to/a from the main body.
[0243] Furthermore, in the configuration with the above rotation timings, the rotation of the toner container 32 is started before the start of a rotation of the driving screw 614 when the toner replenishment is started. Therefore, it is possible to start the rotation of the driving screw 614 after the vicinity of the nozzle opening 610 of the driving nozzle 611 is filled with toner. Consequently, the amount of toner carried by one rotation of the transmit screw 614 can become stable from the beginning of the rotation of the driving screw 614. As a result, the stability of the replacement amount of toner can be improved.
[0244] In this way, it is possible to easily perform a configuration, in which the rotation timings of the toner container 32 and the driving screw 614 are differentiated, using independent drive sources, which rotate independently of the toner container 32 and the driving screw 614. Fourth Embodiment
[0245] A fourth embodiment, which is a modification that uses the same drive source to differentiate the rotation timings of the toner container 32 from the third, etc. implementation, will be explained below.
[0246] Setting using the same unit source can be performed using a clutch. By using the same drive source, configuration to differentiate rotation timings can be carried out at low cost.
[0247] An example of a trigger transmitter to differentiate rotation timings using the same trigger source is illustrated in figures 30A and 30B. Figure 30A is a front view of the unit's transmitter. Fig. 30B is an explanatory side cross-sectional view of the unit transmitter taken along HH in Fig. 30A.
[0248] The drive transmitter illustrated in Figures 30A and 30B includes drive gear 601 fixed to a toner 25, container drive shaft 650 and an idler gear 653 which is arranged to rotate with respect to the container shaft. toner 650. A gear surface hole 653a is formed to follow the partial perimeter of idler gear 653 along the direction of idler gear 653. A drive pin 652 is secured to container drive gear 601 so as to be engaged with the gear surface hole 653a. As illustrated in Fig. 30A, a delay generate spring 651 is provided, one end which is secured to idler gear 653 by spring clamping pin 651a and the other end which is secured to drive pin 652.
[0249] On the front face of the idler gear 653, a circular spring conducting plate 655 is provided which is concentric with the idler gear 653 and which is disposed on the inner side of the hole gear surface 653a such that the spring The generate delay 651 extends along the outer surface of the circular spring lead plate 655.
[0250] In addition, drive screw gear 605 is provided, which is fixed to the drive screw shaft 614, which is with idler gear 653 coupled to the rotating gear, and which transmits idler gear rotation. 653 for drive screw 614.
[0251] In the drive transmitter illustrated in figures 30A and 30B, when a drive motor (not shown) rotates shaft toner container 650 heading in the direction of arrow I in figure 30A, drive gear container 601 rotates. In addition, drive pin 652 integrated with container drive gear 601 rotates along gear surface hole 653a disposed in intermediate gear 653.
[0252] If container drive gear 601 rotates by approximately 180, when drive pin 652 is located in a position indicated by a solid line in figure 30A, drive pins 652 abut against hole of gear surface 653a as indicated by a dashed line in Figure 30A. When the container drive gear 601 in the contacted contact state further rotates, the idler gear 653 is rotated. Consequently, drive screw gears 605 rotate through idler gear 653, and drive screw 614 begins to rotate.
[0253] In this way, a time elapsed to move the drive pin 652 along the gear surface hole 653a after the drive shaft toner container 650 starts to rotate, causes a time lag between the beginning of the container rotation. of toner 32 and a start of rotation of the screw carriage 614.
[0254] This time, the delay generate spring 651 extends for a length corresponding to the partial perimeter along the outer surface of the circular spring lead plate 655.
[0255] On the other hand, when the drive motor stops the rotation of the toner container of the drive shaft 650, the rotation of the drive pin 652 is stopped. This time, a lag force generating spring 651, one end of which is attached to drive pin 652 and which has been extended from a natural length, acts to retract to the natural length, so that the intermediate gear 653 rotates such that spring clamping pin 651a approaches drive pin 652. Consequently, idler gear 653 rotates by the amount corresponding to gear surface hole 653a (the length approximately corresponding to the partial perimeter). Therefore, after the rotation of the toner container 32 is stopped, the driving screw 614 can be rotated by the amount corresponding to the rotation of the idler gear 653 caused by the delay generate spring 651.
[0256] In this case, it is possible to set a desired driving time interval by appropriately setting various parameters. Examples of parameters include the number of teeth of idler gear 653 or drive screw gear 605, movable range of drive pin 652 (the surface hole opening range 653th idler gear), a conveyor field of screw 614, and the width of the nozzle opening 610.
[0257] Furthermore, after the rotation of the toner container 32 is stopped, it is desirable to stop the driving screw 614 after the driving screw 614 is rotated by at least the amount of transport corresponding to the longitudinal width of the opening. of nozzle 610 of the drive nozzle 611. Consequently it becomes possible to transmit the remaining toner T near the nozzle opening 610 of the drive nozzle 611 to the side of the toner discharge passage 64 with respect to the position facing the opening of nozzle 610. With this transport, it is possible to more reliably prevent scattering and dropping of toner due to the attachment/separation of the toner container 32 to/from the main body.
[0258] Furthermore, after the rotation of the toner container 32 is started, it is desirable to start the rotation of the driving screw 614 after the toner container 32 is rotated by at least the amount of transport through which the opening of nozzle 610 of drive nozzle 611 is filled with toner T. Consequently, the stability of the amount of replacement toner can be further improved.
[0259] Explanation will be made of the portion engaged between the common toner container 32 for the first through twentieth embodiments and the container adjustment section 615 and related configurations.
[0260] As described above, the position at which the cylindrical container opening 33a and the container adjustment section 615 slidingly contact each other and the position at which the position of the toner container 32 with respect to the device Toner replacement 60 is determined is indicated by A in figure 9. Position a in figure 9 does not necessarily function both as a sliding section and a positioning section, but may function only as a sliding section and positioning section .
[0261] The toner container 32 according to the present embodiment includes the nozzle receiver 330, which is disposed in the opening of the container body 33 and which includes the receiving opening 331 and 335b of the space between the supporting side portions . The receiving opening 331 is a portion into which the driving nozzle 611 with the nozzle opening 610 as a powder receiving opening is inserted. The space 335b between the support side portions is replacing the opening for supplying toner, as a powder, from the container body 33 to the nozzle opening 610. The toner container 32 also includes the container shutter 332 which is supported by the nozzle receiver 330 and which functions as an open/close member for opening and closing the receiving opening 331 by sliding in the direction of the axis of rotation along with the insertion and removal of the driving nozzle 611 to and from the receiver. nozzle 330. With this configuration, the toner container 32 can maintain the closed state of the receiving opening 331 until the driving nozzle 611 is inserted, and can prevent leakage or scattering of toner before the toner container 32 is attached to the toner replacement device 60.
[0262] When the drive nozzle 611 is inserted into the receiving opening 331 and the container shutter 332 to be pushed by the drive nozzle 611 slides to the rear side of the container, toner accumulates near the space 335b between the support side is pushed away portions. Consequently, a space for the insertion of the drive nozzle 611 can be secured close to the space 335b between the support side in portions and the area where the receiving opening 331 is formed. Consequently, it is possible to reliably provide toner from the 335b space between the support side portions of the receiving opening 331.
[0263] In this way, the toner container 32 can prevent the toner contained in the container body 33 from leaking or scattering before the toner container 32 is attached to the toner replacement device 60, reliably and can discharge the toner to the outside of the container body 33 when the toner container 32 is attached to the toner reset device 60.
[0264] In the toner container 32, as illustrated in figure 1 and figure 7, the receiving opening 331 is formed on the rear end side of the container relative to the front end of the container of the front end opening 305, i.e., at a position at the rear of the opening formed by the tube-shaped opening front end 305.
[0265] Figures 64A and 64B are explanatory diagrams of the toner container 32 according to a comparative example, in which the position of the receiving opening 331 in the direction of the opening rotation axis is the same as the front end of the receiving opening. front end opening 305. Figure 64A is an explanatory perspective view of the vicinity of the front end of the toner container 32. Figure 64B is an explanatory cross-sectional view of the front end of the toner container 32.
[0266] In the same way as the toner container 32 according to the embodiments described above with reference to figure 1 to figure 21, the toner container 32 illustrated in figures 64A and 64B can maintain the closed state of the receiving opening 331 up to that the drive nozzle 611 is inserted and can prevent leakage or scattering of toner before the toner container 32 is attached to the toner replacement device 60. When the drive nozzle 611 is inserted into the receiving opening 331 and the shutter of container 332 is pushed by the drive nozzle 611 slides to the rear side of the container, toner accumulated near the space 335b between the side support portions is pushed away. Consequently, it is possible to reliably discharge toner out of the container body 33 when the toner container 32 is attached to the toner reset device 60.
[0267] The toner container 32 illustrated in Figures 64A and 64B is configured such that the toner in the container body 33 is supplied to the nozzle opening 610, which is disposed in the portion of the driving nozzle 611 inserted into the container body. 33. In this configuration, a contact section, which is between the container seal 333 as a container body sealing member 33 and the driving nozzle 611 and in which toner leakage is likely to occur, is separated from the nozzle opening 610 through which toner is supplied from the container body 33 to the driving nozzle 611. Therefore, if the toner reset operation is performed while the toner container is completely fixed to the toner reset device 60, through the toner container 32 of the comparative example illustrated in Figures 64A and 64B can prevent toner leakage in the contact section between the container seal 333 and the drive nozzle 611 separate from the nozzle opening 610.
[0268] However, when the drive nozzle 611 is inserted into the canister body 33, the outer surface of the drive nozzle 611 is in contact with the toner in the canister body 33. A portion of the contacted toner remains attached to the drive nozzle 611 , when the drive nozzle 611 is removed from the toner container 32 (when removed from the toner reset device 60). Most of the toner attached to the drive nozzle 611 is scraped off by the canister seal 333 when the drive nozzle 611 passes through the contact section with the canister seal 333. However, a small amount of toner may pass through the canister seal. container 333 together with drive nozzle 611, resulting in toner leakage. Leaked toner may come around the outer surface of the toner container 32 of the cylindrical container opening 33a or it may adhere to the inner surface 615a of the container configuration section 615, so that a mismatch may occur when the toner container 32 is again fixed for replacement, etc., or an aggregation of the affixed toner may be disengaged, resulting in an image defect.
[0269] On the other hand, in the toner container 32 according to the first to twentieth embodiment, as illustrated in figure 1, for example, the front edge of the container body 33 projects in the direction of the axis of rotation with respect to the vertical surface of the nozzle receiver 330, where the receiving opening 331 is open. Specifically, in the toner container 32, the position of the opening receiving opening 331 is located at the rear end side relative to the front end container of the front end opening 305 which is the position of the opening container body 33.
[0270] In this way, as the position of the opening receiving opening 331 is located at the rear side in relation to the position of the opening container body 33, it is possible to prevent toner from adhering to the outer surface of the cylindrical container opening 33a. This is because, even though the toner is leaked when the drive nozzle 611 is removed from the toner container 32, the leaked and dispersed toner from the receiving opening 331 is not likely to get around to the front end of the toner container. cylindrical vessel opening 33a. In addition, the leaked toner is withdrawn from the receiving opening 331 and hanging on the lower inner surface of the front end opening 305. Consequently, it is possible to prevent the toner from adhering to the inner surface 615a of the container configuration section 615. In this way, it is It is possible to keep the leaked toner from the receiving opening 331 in a zone bounded by the inner surface of the cylindrical part 33-A container opening. As a result, it is possible to prevent the toner from being scattered to the outside of the toner container.
[0271] As illustrated in figure 1 and figure 9, according to the first to twentieth embodiment, the container configuration section 615, which functions as a rotary axis positioning section and a toner container receiving section 32 is separate with a nozzle opening space 610 in which toner leakage can occur, compared to a case where the toner container 32 according to the comparative example illustrated in Figures 64A and 64B is attached. In addition, the front end of the cylindrical container opening 33a, which functions as a positioning section and an axis of the toner container 32 on the side of the toner container 32 of rotation, projects from the nozzle opening 610 in which toner leaks may occur. In the space between the container configuration section 615 and the receiving opening 331, the nozzle plug flange 612a and the nozzle plug spring 613 are disposed. Therefore, even during the attachment/detachment operation, it is possible to prevent the toner from coming around and adhering to the inner end surface 615b of the container configuration section 615 or to the cylindrical container opening container front end 33a.
[0272] The container shutter 332 which seals the receiving opening 331 being a toner discharge opening of the toner container 32 is disposed on the rear side relative to the front end of the container of the front end opening 305 of the container body 33. With this arrangement, it is possible to ensure a certain distance from the container plug 332 to the front end of the front end opening container 305. Consequently it is possible to prevent the toner from reaching the outer surface of the front end opening 305 through from the opening position of container body 33 from that receiving opening 331 which is located on the rear side with respect to the opening position of the container body 33. As a result, it is possible to avoid dispersion of toner.
[0273] As described above, the position of the toner container 32 relative to the toner replacement device 60 in the direction perpendicular to the axis of rotation is determined based on the fit between the outer surface of the front end opening 305 and the inner surface cylindrical 615a of the container configuration section 615. Specifically, the outer surface of the cylindrical container opening 33a of the container body 33 being a powder storage device serves as a positioning section with respect to the toner replacement device 60 being a powder transport device. Therefore, if the cylindrical outer surface 33a of the container opening becomes soiled with toner when fitted, the inner surface of the container fitting section 615 can be modified and the positioning accuracy can be reduced. On the other hand, the toner container 32 according to the present embodiment can prevent toner reaching the outer surface of the cylindrical container opening 33a, the positioning accuracy of the toner container 32 with respect to the toner reset device 60 can be stabilized.
[0274] Furthermore, in the contact section between the outer surface of the cylindrical container opening 33a and the inner surface of the container configuration section 615, they also slide against each other when the toner container 32 rotates. Specifically, the outer surface 33 of the cylindrical container opening 33a being the powder storage container opening serves as a slide section with respect to the toner replenishment device 60 being the powder driving device. If toner enters the slip section, a charge slip increases and the rotation torque of toner container 32 can be increased. On the other hand, the toner container 32 according to the present embodiment can prevent toner from reaching the outer surface of the cylindrical container opening 33a and prevent toner from entering the contacting section of the inner surface of the container fitting section. 615. Consequently, it is possible to avoid an increase in the sliding load and stabilize the sliding performance, allowing to avoid an increase in the rotation torque of the toner container 32. In addition, it is possible to prevent the toner from entering the sliding section , so that it is possible to prevent the toner from being aggregated when being pressed into the sliding section.
[0275] Furthermore, as described above, when the toner container 32 is attached to the toner replacement device 60, the container seal 333 is pressed down by the nozzle plug flange 612a. Consequently, the nozzle plug flange 612a is pressed firmly against the container seal 333 so that toner leakage can be more reliably prevented. By making the container plug 332 on the inner side (rear end container side) relative to the open position, in the longitudinal direction, a cylindrical space is formed between the front end of the toner container 32 and the front end surface of the container seal 333.
[0276] The common toner container the first through the twentieth embodiment illustrated in figure 1 will be explained below with reference to the schematic diagrams of figures 31A and 31B.
[0277] Figures 31A and 31B are explanatory diagrams for comparing a case where the position of a front surface 330f of the front end of the nozzle receiver container 330 is the same as the position of an edge (edge) 305f of the front end of container of the cylindrical container opening 33a in the direction of the axis of rotation and a case where the front surface 330f is located on the side of the rear end of the container with respect to the edge 305f. At the front surface 330f of the front end of the mouthpiece receiver container 330, the receiving opening 331 is open. Fig. 31A is an explanatory process diagram that the position of the front surface of the receiver 330f nozzle 330 is the same as the position of the edge 305f of the cylindrical container opening 33a in the direction of the axis of rotation. Fig. 31B is an explanatory diagram illustrating the case where the position of the front surface 330f of the nozzle receiver 330 is located on the rear end side of the container with respect to the position of the edge 305f of the cylindrical container opening 33a in the axis direction. of rotation.
[0278] In the toner replacement device 60 illustrated in figures 31A and 31B, before the drive nozzle 611 is inserted into the nozzle 331 that the nozzle receiver receiving opening 330, the nozzle shutter 612 is pressed by the shutter spring of nozzle 613 in the nozzle insertion direction (to the right in figure 31B). Consequently, the nozzle plug 612 is located near the front end of the drive nozzle 611 and closes the nozzle opening 610. This time, one end of the nozzle plug spring 613 abuts against the rear side of the nozzle plug flange 612a as a nozzle plug positioning portion 612, and the other end of the nozzle plug spring 613 abut against the end surface 615b of the toner reset device 60.
[0279] The toner container 32 being a powder container is slid in the direction of the arrow Q (in the fixing direction) in figures 31A and 31B, so as to be attached to the toner replacement device 60 illustrated in figures 31A and 31B . Together with the accessory, the nozzle plug 612 is biased by the nozzle plug spring 613 in a direction opposite to the direction Q points against the front surface 330f of the front end of the nozzle receiver 330, where the receiving opening 331 of the nozzle receiver 330 is open. Thereafter, when the toner container 32 further slides in the Q direction, the nozzle plug 612 moves in the Q direction relative to the drive nozzle 611 to be inserted into the toner container 32. In this way, the nozzle plug 612 moves one moves to the base end of the drive nozzle 611 and the drive nozzle 611 is opened. Then, as illustrated in Figures 31A and 31B, the nozzle opening 610 is fully open after the toner container 32 is attached to the toner reset device 60.
[0280] With the movement of the nozzle plug 612 towards the base end of the driving nozzle 611, the nozzle plug spring 613 is compressed. As illustrated in Figures 31A and 31B, the length of the nozzle shutter spring 613 in the direction of the axis of rotation becomes shorter when the toner container 32 is attached to the toner reset device 60. Even in this state, however, the nozzle plug spring 613 has a certain length in the direction of the axis of rotation. Therefore, a housing space (with length W in the direction of the axis of rotation) is required between the front surface 330f of the nozzle receiver 330 and the end surface 615b of the toner replacement device 60. The housing space is a space for housing the front end side portion of the nozzle plug container 612 relative to the nozzle plug flange 612a and for housing the nozzle plug spring 613.
[0281] In addition, the nozzle opening 610 has to reach a position where toner can be received. The optimal position of the nozzle opening 610 is determined based on the shape of the container body 33. Therefore, if the shape of the container body 33 is identical, in the case of Figures 31A and 31B, a distance 305f from the container end opening cylindrical 33a of the container body 33 for the optimum position of the nozzle opening 610 in the direction of the axis of rotation is constant.
[0282] In the above configuration, if the toner container 32 is configured as illustrated in figure 31A, the following problem may occur. In the configuration illustrated in Figure 31A, the front edge position 305f of the cylindrical container end opening 33a in the direction of the axis of rotation and the position of the front surface of the receiver 330f nozzle 330, where the receiving opening 331 is open in the direction of the axis of rotation are the same.
[0283] Therefore, a distance (LI) from the end surface 615b of the toner replacement device 60 to the inlaid portion 615s becomes longer than the length (W) of the housing space in the axis direction of rotation. Therefore, the size of toner replacement device 60 increases.
[0284] If the shape of the container body 33 is identical, a distance from the edge 305f of the cylindrical container opening 33a to the optimal position of the nozzle opening 610 in the direction of the axis of rotation is constant. Furthermore, the position of the edge 305f cylindrical container opening 33a as a starting point for determining the position of the nozzle opening 610 in the direction of the axis of rotation is separated from the end surface 615b of the toner replacement device 60 by the length. (W) of the housing space or more in the direction axis rotation. Therefore, a distance (L2) from the end surface 615b of the toner reset device 60 to the front end of the drive nozzle 611 increases, so that the size of the toner reset device 60 is increased.
[0285] Furthermore, the edge position 305f of the cylindrical container opening 33a, which is the front end of the toner container 32, is separated from the end surface 615b of the toner replacement device 60 by the length W of o housing space in the direction axis rotation. Therefore, a distance (L3) from the end surface 615b of the toner replacement device 60 to an end of the toner container 32 increases, so that the size of the toner replacement device 60, which holds the toner container 32 is increased.
[0286] In the configuration shown in Figure 31B, the front surface (330f in Figures 31A and 31B) of the nozzle receiver 330, where the receiving opening 331 is open is located on the rear end side of the container relative to the front end of cylindrical container opening container 33a. The front surface of the nozzle receiver 330, where the receiving opening 331 is denoted open 330f in Figures 31A and 31B, and the front surface of the container seal 333 correspond to the front end of the nozzle plug positioning ribs 337a. Therefore, when the toner container 32 is attached to the toner replacement device 60, the nozzle plug flange 612a of the nozzle plug 612 abuts against the front surface 330f on the side of the rear end of the container with respect to the front end of the cylindrical container opening 33a in the direction of the axis of rotation. Consequently, at least a part of the housing space is located in the circular space formed between the position of the front end opening 305 (the front end of the container) and the front surface of the container seal 333. Therefore, the distances L1, L2, L3 and in figures 31A and 31B can be made shorter than those illustrated in figure 31A (by La in figure 31A).
[0287] If the size of the toner replacement device 60 does not need to be reduced, the container body 33 can be made longer by La in the direction of the rotation axis. Therefore, the amount of toner contained in the toner container 32 can be increased.
[0288] The nozzle plug 612 closes the opening 610 of the nozzle of the drive nozzle 611 when the toner container 32 is not attached to the toner reset device 60. When the toner container 32 is attached to the toner reset device toner 60, the nozzle shutter 612 needs to be opened in order to receive the toner.
[0289] In the toner replacement device 60, the cylindrical space (the front end opening 305) is formed between the container front end of the cylindrical container opening 33a and the end surfaces of the container shutter 332 and the seal of container 333 on the front side of the container. The housing space is configured so that all or a part of the obturator nozzle 612 can be housed when the obturator nozzle 612 is opened. In the housing space, all or a part of the nozzle plug spring 613 for closing the nozzle plug 612 is also housed. With this configuration, it is possible to reduce the size of a space to arrange the nozzle plug 612 and the nozzle plug spring 613.
[0290] As illustrated in Figure 9, according to the present embodiment, when the toner container 32 is attached to the toner reset device 60, the position of the nozzle plug housing 612 at the front end of the nozzle in relation to the flange of the nozzle plug 612a is located within the container seal 333. The end of the nozzle base relative to the nozzle plug flange 612a is substantially the nozzle housed in the cylindrical space formed between the position of the front end opening 305 (the end front surface of the container) and the front surface 330f of the container seal 333. In addition, the nozzle plug spring 613 in the compressed state is substantially housed in the cylindrical space.
[0291] With this setting, it is possible to reduce the distance from the position of the front end opening 305 being the most end part of the toner container 32 to a toner area opening of the toner replacement device 60 (the position in which the toner discharge passage 64 is connected to the drive nozzle 611). Therefore, the size of the main body can be reduced.
[0292] As explained above with reference to Figure 22 to Figure 28, the first ends 612b inner rib against a leading edge of the nozzle opening 610, i.e., the upper inner surface of the front end 611a of the driving nozzle 611, while the 612 nozzle shutter is closed. Therefore, a function can be performed to prevent the nozzle plug 612 from coming out. Furthermore, the front end 612g of the first inner rib 612b, which is the end of the first inner rib 612b in the circumferential direction, points against the nozzle opening 611s rim which is an edge of the nozzle opening 610 in the lateral direction. Therefore, a function to prevent rotation of the nozzle plug 612 can be performed. The function to prevent rotation of the nozzle plug 612 may be available in the same way even when the toner container 32 is attached to the toner reset device 60.
[0293] Furthermore, as described above, the inner diameter of the second inner rib 612c and the third inner rib 612d is slightly smaller than the outer diameter of the drive nozzle 611. For example, when the outer diameter Φ of the drive nozzle 611 is 15 mm, it is preferable to set the inner diameters Φ of the second inner rib 612c and the third inner rib 612d to approximately 14.8 mm and 14.9 mm. In this way, the second inner rib 612c and the third inner rib 612d in the form of cylinders with the inner diameters slightly smaller than the outer diameter of the drive nozzle 611 are formed on the inner surface of the nozzle plug 612. Therefore, it is possible fill the space between the inner surface of the nozzle plug 612 and the outer surface of the driving nozzle 611. Consequently it becomes possible to carry out the toner sealing function without a seal, so that the seal such as sponge or rubber , it's not necessary. Since a separate 612 nozzle plug seal is not required, it is possible to prevent toner leakage at lower costs.
[0294] As a configuration to prevent toner leakage, it may be possible to provide an annular seal instead of the second inner rib 612C and the third inner rib 612d. However, as the distance between the inner surface of the nozzle plug 612 and the outer surface of the drive nozzle 611 is extremely small, the annular seal cannot be inserted. Therefore, if the annular seal is arranged, an annular plug seal nozzle 612h needs to be arranged in the manner illustrated in Figures 65A and 65B. In this case, the outer diameter of a receiving plug seal nozzle 612j is made smaller than the diameter of the plug nozzle spring 613 so that the nozzle plug spring 613 can abut against the nozzle plug spring receiving surface 612f.
[0295] To mount the nozzle plug 612 on the drive nozzle 611, the nozzle plug 612 is temporarily deformed. Therefore, the nozzle plug 612 needs to be elastically deformable to some extent. This is because, if a hard and less elastically deformable material is used, the nozzle plug 612 can be split without being elastically deformed when it is assembled. Nozzle plug 612 is made of a material with suitable elasticity. For example, when the outer shape of the drive nozzle 611 is a cylinder, the nozzle plug 612 is formed cylindrical in shape, with the inner diameter slightly larger than the outer diameter of the drive nozzle 611. Inner rib 612b as an inwardly protruding protrusion is formed on the inner portion of the nozzle plug 612. The first inner rib 612b is arranged to confront the nozzle opening 610 of the drive nozzle 611 so that it is possible to carry out the function to prevent the nozzle plug from rotating. A portion of the drive nozzle 611 to be engaged with the nozzle plug protrusion 612 is not limited to the nozzle opening 610. While the protrusion may function to prevent rotation and exit, any portion of the lead nozzle 611 can be used.
[0296] According to experiments carried out by the inventors of the present invention, it is preferable to choose a resin material with a tensile modulus of elasticity of 500 MPa to 2000 MPa, as the material of the nozzle plug 612. When the nozzle plug 612 is mounted on the drive nozzle 611, the three ribs (612b to 612d) formed on the inner surface of the nozzle plug 612 act as a resistor, while the drive nozzle 611 is inserted into the nozzle plug 612. The resistance increases when the first rib inner 612b enters nozzle opening 610 over front end 611a of the nozzle.
[0297] This time, if the nozzle plug 612 is made of a material with certain elasticity, the nozzle plug 612 is deformed and can be mounted easily. Furthermore, a sliding load caused by squeezing the second inner rib 612c and the third inner rib 612d by the drive nozzle 611 is not increased, which is an advantage.
[0298] Incidentally, if the nozzle plug 612 is extremely deformable, the function of preventing coming out and rotation of the first inner rib 612b is reduced.
[0299] As a material with certain elasticity applicable to the nozzle plug 612, when polyethylene or polypropylene was selected, the above-described advantage was stably obtained. Furthermore, it is preferable to adjust the thickness of the nozzle plug tube 612 and the nozzle plug 612 from 0.3mm to 0.5mm.
[0300] If the nozzle plug 612 has the property of material and shape as described above, it is possible to reduce the costs of a plug structure that opens and closes the nozzle opening 610. In relation to the toner container 32, in the state of being stored, a common lid 370 for the first to fourth embodiments will be explained below.
[0301] Figure 32 is an explanatory perspective view of the toner container 32, in the state of being stored, and the lid 370 is fixed to the toner container 32. The lid 370 is to serve as a sealing member that seals the opening of the front end opening 305 of the toner container 32 illustrated in Figure 6. Figure 33 is an explanatory cross-sectional view of the vicinity of the front end of the toner container 32 so that the cap 370 is secured.
[0302] The toner container 32 illustrated in Fig. 32 includes an invention as described below. Specifically, the toner container 32 is a powder container, which contains toner as a powder developer. The cap 370 which serves as a sealing member that seals the receiving opening 331 which serves as a developer outflow opening may be secured to the cylindrical container opening 33a of the toner container 32. As described above, the cylindrical container opening 33a is a part of the container body 33. As illustrated in Figure 1, Figure 6, and Figure 7, for example, in the container body 33, the cylindrical container opening 33a is formed to penetrate through the end cap. container front 34 which is necessary to set the toner container 32 to the toner reset device 60. Therefore, it is possible to expose the cylindrical container opening 33a to the container body 33 from the container front end cap 34. Since the cylindrical container opening 33a being a part of the container body 33 which contains the toner can be directly sealed by the cap 370, the sealing effect can be improved and the flow. Toner build-up can be more reliably prevented.
[0303] In the common toner container 32 of the first through twentieth embodiments, a lid flange 371 is provided on the lid 370. When the lid 370 is attached to the toner container 32, the lid flange 371 hides the arranged identification tag 700. on the container front end cap 34, as illustrated in figure 32. It is therefore possible to prevent the identification tag 700 from being contacted or subjected to impact from the outside, when the toner container 32 is stored, enabling the tag to be protected. identification 700.
[0304] Furthermore, in the toner container 32 according to the first to fourth embodiments, the outer diameter of the lid flange 371 of the lid 370 is made larger than the diameters of the container front end lid 34 and the body of container 33. Therefore, it is possible to prevent the toner container 32 from being broken when it is released, allowing to protect the toner container 32.
[0305] Furthermore, the cylindrical container opening 33a being a part of the container body 33 is directly sealed by the cap 370. Consequently, the sealing effect can be improved compared to the configuration where the cylindrical container opening 33a is sealed by means of an element (eg the container front end cap 34) separate from the container body 33. For the cylindrical container opening 33a to be directly sealed, it is possible to hermetically seal the container body 33. To the container body container 33 can be hermetically sealed, it is possible to prevent air or moisture from entering the container body 33. Consequently it becomes possible to reduce the packaging materials for packing the toner container 32.
[0306] When the toner container 32 is used (when it is attached to the toner replacement device 60), the cover 370 is detached. As a method for securing the lid 370 to the toner container 32, any method, such as a screw-on method or a snap-on method, can be used, as long as the lid 370 can be secured. In this case, a toner container fixing part 32, such as a male screw for the screwing method or a portion engaged in the engagement method, is formed on the outer surface of the cylindrical container opening 33a exposed from the end cap front of container 34. In the toner container 32 according to the embodiments, as illustrated in figure 33, a male screw 309 for screwing the plug is disposed on the outer surface of the cylindrical container opening part 33a and the threading method is employed as the method for fixing the sealing element.
[0307] The configuration to seal the opening formed by the cylindrical container opening 33a is not limited to the configuration in which the cap 370 is secured by the screw-on method. It may be possible to seal the opening by pressing a film member at the front end of the cylindrical container opening 33a. Fifth Achievement
[0308] A fifth embodiment will be explained below, in which the cap 370 is provided with an absorbent (an adsorption material).
[0309] The toner container 32, which uses an absorbent such as a drying agent, when the container is stored toner will be explained below. The absorbent functions to absorb not only moisture but also various substances (gas or the like). Therefore, the absorbent includes a desiccant. Examples of the absorbent include silica gel, aluminum oxide and zeolite. However, any substance with adsorption capacity can be used.
[0310] When the container body 33 is completely sealed by the cap 370, the entry of air or moisture can be prevented. Therefore, the absorbent is not necessary, and the packaging materials are not necessary either. In this method, it is possible to reduce packaging materials, such as a bag, a filling material, or an individual box, for packaging the toner container 32 and for reducing the size of a package. As a result, it is possible to reduce the materials to be used, allowing to reduce the environmental burden.
[0311] However, the inventors of the present invention confirmed that the toner powder had to be generated by the gas itself and a cohesion such as a small toner clot had been generated although toner cohesion or solidification did not occur. Such cohesion can become a cause of a dot, such as a white dot or an arbitrary color dot, resulting in an abnormal image. Therefore, cohesion must be avoided. If non-gas-generating toner itself is used, it is possible to omit the absorbent for the seal as illustrated in figure 33. However, as the toner container 32 contains the gas-generating toner by itself, it is preferable provide an absorbent that absorbs the gas.
[0312] Figure 34 is an explanatory sectional view of a first example of the toner container 32 when the cap 370 is provided with an absorber 372. The toner container 32 illustrated in Figure 34 includes an invention as described below. Specifically, the toner container 32 shown in Figure 34 is configured such that the absorber 372 is provided over the cap 370 in the toner container 32 shown in Figure 33. In the toner container 32 shown in Figure 34, the absorber 372 can be separated together with the cap 370 when the cap 370 is removed to use the toner container. Consequently, the operability can be improved.
[0313] However, in the configuration illustrated in Figure 34, the absorber 372 is exposed to outside air around the toner container 32. Consequently, a packaging material is required. Sixth Achievement
[0314] A second example of the cap 370 provided with the absorbent will be explained below as a sixth embodiment.
[0315] Figure 35 is an explanatory cross-sectional view of the second example of the toner container 32 when the cap 370 is provided with the absorber 372. The toner container 32 illustrated in Figure 35 includes an invention as described below. Specifically, the toner container 32 illustrated in Figure 35 contains toner as a powder developer within it. The toner container 32 is a powder container wherein the lid 370, as a sealing member for sealing the receiving opening 331 as a developer discharge opening, can be secured to the cylindrical container opening 33a forming the opening of the front end so as to seal the interior of the container body 33. In the toner container 32 shown in Figure 35, the absorber 372 is provided within the cap 370 which hermetically seals the front end opening.
[0316] In the toner container 32 shown in Figure 35, the absorber 372 is provided in the cap 370. Therefore, similarly to the toner container 32 shown in Figure 34, it is possible to separate the absorber 372 together with the cap 370 when the lid 370 is removed to use the toner container so that operability can be improved.
[0317] In addition, as a space to contain toner (the inner space of the container body 33) is hermetically sealed by the lid 370, it is possible to prevent air or moisture from entering the space where the toner is stored. In addition, as the absorbent 372 is provided inside the hermetically sealed • space, it is possible to adsorb toner generated gas by itself. Therefore, the adsorption performance can be improved compared to the toner container 32 illustrated in Fig. 34. Furthermore, as the space for containing the toner (the inner space of the container body 33) is hermetically sealed and the absorber 372 is provided within the hermetically sealed space, both of the toner and the absorbent 372 are not influenced by external air around the toner container 32. Consequently, a packaging material is not required. Seventh Achievement
[0318] A third example of the cap 370 provided with an absorbent will be explained below as a seventh embodiment.
[0319] Figure 36 is an explanatory cross-sectional view of the third example of the toner container 32 when the cap 370 is provided with the absorber 372. The toner container 32 illustrated in Figure 36 includes an invention as described below. Specifically, the toner container 32 shown in Fig. 36 contains toner as a powder developer within it. The toner container 32 is a powder container wherein the lid 370, as a sealing member for sealing the receiving opening 331 as a developer discharge opening, can be secured to the cylindrical container opening 33a forming the opening of the front end so as to seal the interior of the container body 33. In the toner container 32 shown in Figure 36, the absorber 372 is provided within the cap 370 which hermetically seals the front end opening. In addition, the toner container 32 illustrated in Figure 36 is arranged so that at least a portion of the absorber 372 is housed in a recess (the front end opening 305) in the front end of the toner container 32. The recess at the front end of the toner container 32 is a cylindrical space formed between the front side end of the front end opening 305 and the front side end of the container seal 333.
[0320] In the toner container 32 shown in figure 36, the absorber 372 is provided in the cap 370. Therefore, similarly to the toner container 32 shown in figure 34 and figure 35, it is possible to separate the absorber 372 together with the cap 370 when cap 370 is removed to use the toner container, so that operability can be improved.
[0321] Furthermore, similarly to that of the toner container 32 illustrated in Figure 35, because the space for which it contains the toner (the internal space of the container body 33) is completely sealed by the cap 370, it is possible to prevent the air or moisture enters the space containing the toner. Furthermore, as the absorbent 372 is provided within the hermetically sealed space, it is possible to adsorb gas generated by the toner itself. Consequently, the adsorption performance can be improved compared to the toner container 32 illustrated in Fig. 34. Furthermore, as the space for containing the toner (the inner space of the container body 33) is hermetically sealed and the absorber 372 is provided in the hermetically sealed space, both of the toner and the absorbent 372 are not influenced by external air around the toner container 32. Consequently, a packaging material is not required.
[0322] The toner container 32 illustrated in Figure 36 is arranged such that at least a portion of the absorber 372 is housed in the recess at the front end of the toner container 32. Consequently, in addition to the same advantageous effects as the Toner container 32 illustrated in Fig. 35, it is possible to reduce the length of the cap 370 in the direction of the axis of rotation. As a result, it is possible to reduce the size of the toner container 32 in the state of being stored.
[0323] In the configuration where the toner container 32 is sealed by the lid 370, it may be possible to improve the sealing performance between the cylindrical container opening 33a of the toner container 32 and the lid 370, using a packaging material or the like .
[0324] In the configuration where the absorber 372 is provided in the cap 370, the absorber 372 can be integrated with the cap 370 (attached to the cap 370) or can be separated from the cap 370 (not attached to the cap 370). However, when the absorber 372 is fixed and integrated with the cap 370, because it becomes possible to separate the absorber 372 together with the cap 370, it is possible to prevent the absorber 372 from not remaining separated in error and improve operability.
[0325] A problem with a conventional toner container that cannot seal directly to the space containing the toner (the container body) by a sealing element will be explained below.
[0326] In recent years, the toner used in imaging apparatus has more improved fixing ability at low temperature and a smaller diameter, so the heat resistance performance tends to become lower. So, for example, if the toner is subjected to a high temperature environment during transport, the toner is adhered, and in the worst case, solidified. Consequently, toner cannot be supplied from the toner container to an image forming apparatus. It is known that toner cohesion and solidification are much more likely to occur at higher humidity if the ambient temperature is the same. A delivery path from a toner container to a user varies and it is impossible to control the environment of all routes. For example, when land, air, and sea transportation are available, it is difficult to manage temperature and humidity on all routes.
[0327] As a measure to deal with the above situation, it may be possible to use a container that can control a transport environment. However, it is almost impossible to introduce the container in all transport routes, and there is a problem with an increase in costs. With regard to the above issues, as the toner container 32 according to the embodiment can seal the lid directly by the cylindrical container opening 33a being a part of the container body 33 which contains the toner, the sealing effect can be improved and toner leakage can be more reliably prevented. Furthermore, as the sealing effect is improved, the toner container 32 is less likely to be influenced by an outside environment when the toner container 32 is stored.
[0328] Furthermore, as the attachment of the toner container 32 to the replacement toner device 60 is made possible by separating the cap 370 from the replacement toner container 32, it is possible to provide a powder container with good usability.
[0329] Furthermore, as the lid 370 has a shape that can protect the identification tag 700 and the toner container 32, it is possible to reduce the filling materials or individual boxes for the packaging of the toner container 32 and reduce the size of a package. used and an environmental burden. eighth achievement
[0330] As an eighth embodiment, a first example of the toner container 32 which includes the lid 370 provided with a toner leakage preserver will be explained below.
[0331] After the toner container 32 is the powder container being dispensed to a user, the toner container 32 is normally handled by the user. Consequently, the toner container 32 can be abruptly handled because it is impossible to specifically regulate how to handle the toner container. Therefore, an adequate measure against bouncing or dropping is necessary in order to prevent toner leakage even when the toner container 32 is mishandled.
[0332] With regard to toner leakage, leakage from the receiving port 331 must be avoided. To prevent leakage, it is necessary to prevent toner leakage that can occur when a space is generated between the container seal 333 forming the receiving opening 331 and the container plug 332 that closes the receiving opening 331.
[0333] Figure 37 is an explanatory cross-sectional view of the first example of the toner container 32 when the lid is provided with a toner leakage preserver, according to the eighth embodiment. The toner container 32 illustrated in Figure 37 includes an invention as described below. Specifically, the toner container 32 illustrated in Fig. 37 is a powder container, which includes the container body 33, the container seal 333, the container stopper 332, and the cap 370, and in which a cylindrical member 373 is affixed to cap 370. Container body 33 is a powder storage device which contains toner therein as a powder. The container seal 333 forms the receiving opening 331 which serves as the nozzle receiving opening disposed in the opening at the front of the container body 33. The container shutter 332 is an open/closing member for the receiving opening 331 The cap 370 is a sealing element for opening the front end, i.e., a powder discharge side, of the container body 33. The cylindrical element 373 is the toner leakage preserver.
[0334] In the toner container 32 illustrated in Fig. 37, the cylindrical element 373 is made of a different material from the material of the cap 370, and the cylindrical element 373 is secured to the cap 370 by an adhesive agent or the like. Furthermore, as illustrated in Figure 37, when the cap 370 is attached, a surface of the cylindrical element 373 on an opposite side of the side attached to the cap 370 (the right side in Figure 37) is in contact with the front end surface. of the container of the container closure 332. The cylindrical element 373 is circular in shape with a diameter greater than the diameter of the container closure 332 and less than the annular outer circumference of the container seal 333.
[0335] With this configuration, when the cap 370 is attached to the toner container 32, the surface of the cylindrical element 373 comes in contact with the end surfaces of the container front side of the container plug 332 and the container seal 333, simultaneously. This time, the surface of the cylindrical element 373 comes into contact, so as to fill a boundary between the container plug 332 and the container seal 333. Consequently it becomes possible to directly seal the receiving opening 331 and prevent toner leakage even when a gap is generated between the container seal 333 and the container plug 332 due to the impact caused by swinging or dropping. In this way, the toner container 32 illustrated in Fig. 37 can prevent toner leakage and become effective against bouncing or dropping. Therefore, even when the container 32 is approximately handled toner during transport or the like, it is possible to avoid toner leakage.
[0336] Furthermore, as described above, in which the toner container 32 illustrated in Fig. 37, the cylindrical element 373 is made of a different material than the material of the cap 370. It is therefore possible to form the cap 370 with a less material It is costly, such as polystyrene resin, and to form the cylindrical element 373 with a material having a high flexibility, such as rubber or a sponge. If the cylindrical element 373 is made of a material that has high flexibility, when the cylindrical component 373 comes into contact with the end surfaces on the front end of the container plug 332 and the container seal 333, the sealing performance with respect to found members can be improved. Therefore, the cylindrical element 373 can be made more effective in preventing toner leakage due to the impact caused by swinging or dropping.
[0337] Furthermore, by forming the cap 370 with a less expensive material, such as polystyrene resin, different from the material of the cylindrical element 373, it becomes possible to reduce costs while maintaining the toner leakage prevention function of the member cylindrical 373. Ninth Achievement
[0338] A second example of the toner container 32, which includes the cap 370 provided with the preventative toner leakage will be explained below as a ninth embodiment.
[0339] Figure 38 is an explanatory cross-sectional view of the second example of the toner container 32 when the lid is provided with the toner leakage preserver. The toner container 32 illustrated in Figure 38 includes an invention as described below. Specifically, the toner container 32 illustrated in Fig. 38 is a powder container, which includes the container body 33, the container seal 333, the container stopper 332, and the cap 370, and wherein a cylindrical portion 374 it is integrated with the cap 370. The cylindrical part 374 is the toner leakage preserver.
[0340] In the toner container 32 illustrated in Fig. 38, when the cap 370 is secured, the cylindrical portion 374 contacts the container plug 332. This time, a surface of the cylindrical portion 374 protruding from the cap 370 in the direction of the axis of rotation (the right side in figure 38) is in contact with the container front end surface of the container plug 332 (the left side in figure 38). The surface of the cylindrical portion 374 is circular in shape with a diameter larger than the container plug 332 and smaller than the annular outer circumference of the container seal 333.
[0341] With this configuration, when the cap 370 is attached to the toner container 32, the surface of the cylindrical portion 374 comes in contact with the end surfaces of the container front side of the container plug 332 and the container seal 333, simultaneously. This time, the surface of the cylindrical portion 374 comes into contact, so as to fill a boundary between the container plug 332 and the container seal 333. Consequently it becomes possible to directly seal the receiving opening 331 and prevent toner leakage even when a gap is generated between the container seal 333 and the container plug 332 due to the impact caused by swinging or dropping. In this way, the toner container 32 illustrated in Fig. 38 can prevent leakage of toner and become effective against bouncing or dropping. Therefore, even when the toner container 32 is roughly handled during transport or the like, it is possible to avoid toner leakage. Furthermore, as the cylindrical part 374 can be integrated as a part of the cap 370 (wholly molded) it is possible to reduce costs. tenth achievement
[0342] A third example of the toner container 32 which includes the cap 370 provided with the toner leakage preserver will be explained below as a tenth embodiment.
[0343] Figure 39 is an explanatory cross-sectional view of the third example of the toner container 32 when the lid is provided with the toner leakage preserver. The toner container 32 illustrated in Figure 39 includes an invention as described below. Specifically, the toner container 32 illustrated in Fig. 39 is a powder container, which includes the container body 33, the container seal 333, the container stopper 332, and the cap 370, and wherein the cylindrical portion 374 is integrated with the lid 370. Furthermore, in the powder container, a front elastic member 375 is formed on the end surface of the cylindrical portion 374, in contact with the receiving opening 331. The front end elastic member 375 is made of a material with a high flexibility, such as rubber or a sponge.
[0344] In the toner container 32 illustrated in Figure 39, when the cap 370 is attached, the front elastic element 375 in the cylindrical portion 374 contacts the container front end surface of the container shutter 332 (the left side in the figure 39). The cylindrical part 374 is integrated as a part of the cap 370 and the front elastic element 375 is provided on a surface of the cylindrical portion 374 protruding from the cap 370 in the direction of the axis of rotation (the right side in Fig. 39). The front end elastic member 375 is circular in shape with a diameter greater than the container plug 332 and less than the annular outer circumference of the container seal 333.
[0345] With this configuration, when the cap 370 is secured to the toner container 32, the circular surface of the front end elastic element 375 contacts the container of container plug front end surfaces 332 and the container seal 333 , simultaneously. This time, the final circular surface of the front elastic element 375 comes into contact so as to fill a boundary between the container plug 332 and the container seal 333. Therefore, it becomes possible to directly seal the receiving opening 331 and prevent toner leakage even when a gap is generated between container seal 333 and container plug 332 due to impact caused by swinging or dropping. In this way, the toner container 32 illustrated in Fig. 39 can prevent toner leakage and becomes effective against bouncing or dropping. Therefore, even when the toner container 32 is roughly handled during transport or the like, it is possible to avoid the occurrence of toner leakage. In particular, in the configuration illustrated in Figure 39, the front elastic member 375 is provided in the cylindrical portion 374 of the cap 370. Accordingly, when the front end elastic member 375 contacts the container plug 332 and the container seal 333, it is possible to improve the sealing performance with respect to these parts as compared to the toner container 32 illustrated in figure 38. Therefore, it is possible to further increase the advantageous effect to avoid toner leakage due to the impact caused by the wobble or drop . Eleventh Achievement
[0346] A fourth example of the toner container 32 which includes the cap 370 provided with the toner leakage preserver will be explained below as an eleventh embodiment.
[0347] Figure 40 is an explanatory cross-sectional view of the fourth embodiment of the toner container 32 when the lid is provided with the toner leakage preserver. The toner container 32 illustrated in Figure 40 includes an invention as described below. Specifically, the toner container 32 illustrated in Fig. 40 is a powder container, which includes the container body 33, the container seal 333, the container plug 332, and the cap 370, and wherein the cylindrical portion 374 is provided in the cap 370. In addition, the absorber 372 is disposed within the cylindrical portion 374 so as to be open to the outside, which is so as to be exposed to outside air.
[0348] The toner container 32 shown in Figure 40 is configured by adding the absorber 372 to the toner container 32 shown in Figure 38. Therefore, similarly to the toner container 32 shown in Figure 38, the advantageous effect against wobble or drop can be obtained. Consequently, even when the container 32 is roughly handled toner during transport or the like, it is possible to avoid toner leakage. Furthermore, as the cylindrical part 374 can be integrated as a part of the cap 370 (wholly molded) it is possible to reduce costs.
[0349] Furthermore, as the toner container 32 illustrated in figure 40 is provided with the absorber 372, it is possible to prevent air or moisture from entering the toner container 32. Furthermore, as the absorber 372 is provided in the cylindrical portion 374 formed on cap 370, it is possible to separate absorber 372 together with cap 370 when cap 370 is removed to use the toner container. Consequently, the operability can be improved.
[0350] However, in the configuration illustrated in Figure 40, the absorber 372 is exposed to outside air around the toner container 32. Since the absorber 372 is provided in order to adsorb moisture around the toner container 32, It is necessary to use a packaging material such as a back storage device.
[0351] In a normal situation as long as buffer 370 is sufficient. However, if the cap 370 lacks the sealing capability (if used to reduce impact or the like), providing the cylindrical portion 374 and the adsorption material 372 as illustrated in Figure 40 is effective. Twelfth Achievement
[0352] A fifth example of the toner container 32 that includes the cap 370 provided with the toner leakage preserver will be explained below as a twelfth embodiment.
[0353] Figure 41 is an explanatory cross-sectional view of the fifth example of the toner container 32 when the cap is provided with the toner leakage preserver. The toner container 32 illustrated in Figure 41 includes an invention as described below. Specifically, the toner container 32 illustrated in Fig. 41 is a powder container, which includes the container body 33, the container seal 333, the container stopper 332, and the cap 370, and wherein the cylindrical portion 374 is provided on the cap 370. The cap 370 is connectable to the cylindrical container opening 33a which forms the front end opening so as to seal the interior of the container body 33. In addition, the absorber 372 is disposed within the cylindrical portion 374 so as to adsorb object adsorption in the space sealed by plug 370.
[0354] In addition, the toner container 32 illustrated in Figure 41, as the absorber 372 adsorbs the gas or the like generated by the toner itself, an adsorbent hole 374a as an opening is arranged on the side of the cylindrical portion 374. space sealed by the cap 370 and the space where the adsorbent hole 374a is arranged can communicate with each other.
[0355] The toner container 32 illustrated in Figure 41 is configured by closing the front end surface of the container from the cylindrical portion 374 of the toner container 32 illustrated in Figure 38 and providing the absorbent 372 on the end surface. Consequently, similarly to the toner container 32 illustrated in Fig. 38, the advantageous effect against swaying or dropping can be obtained. Consequently, even when the toner container 32 is roughly handled during transport or the like, it is possible to avoid toner leakage.
[0356] Furthermore, as the toner container 32 illustrated in Figure 41 includes the absorber 372, it is possible to prevent air or moisture from entering the toner container 32. Furthermore, as the absorber 372 is disposed in the cylindrical portion 374 formed on the cap 370, it is possible to separate the absorber 372 together with the cap 370 when the cap 370 is separated to use the toner container. Therefore, the operability can be improved.
[0357] In the toner container 32 illustrated in figure 41, because the space to which contains the toner (the inner space of the container body 33) is completely sealed by the cap 370, it is possible to prevent air or moisture from entering. in the space containing the toner. Furthermore, because the space sealed by the cap 370 and the space where the adsorbent orifice 374a is arranged to communicate with each other, it is possible to adsorb gas generated by the toner itself. Therefore, it is possible to improve the adsorption performance compared to the configuration illustrated in figure 40. Furthermore, because the space for containing the toner (the inner space of the container body 33) is sealed and the absorber 372 is disposed in the space closed, both the toner and the absorbent 372 are not influenced by the external air around the toner container 32. Consequently, a packaging material is not required.
[0358] In the toner container 32 illustrated in Figure 40 and Figure 41, it is explained that the absorber 372 is provided in the cylindrical portion 374 that is integrated with the cap 370. However, as the preventative toner leakage, where the absorber 372 is provided, as illustrated in Fig. 37, the cylindrical element 373 separate from the cap 370 may be used.
[0359] In the toner container 32 illustrated in Figure 37 to Figure 41, a screw-on method is employed as the method for securing the cap 370 that serves as the sealing element. However, as the method for securing the cap 370 to the toner container 32, any method, such as a screw-on method or a snap-on method, can be used, as long as the connection can be secured, similarly to the configuration explained above. with reference to figure 33.
[0360] In the toner container 32 illustrated in figure 37 to figure 41 (eighth to twelfth embodiment), the cylindrical element 373, the cylindrical part 374, or the front elastic element 375 presses the container plug 332 and the container seal 333. Therefore, the toner container 32 becomes effective against impacts caused by swinging or dropping. Consequently, even when the container 32 is roughly handled toner during transport or the like, it is possible to avoid toner leakage.
[0361] Furthermore, because the cylindrical element 373, the cylindrical part 374, or the front end elastic element 375 presses the container plug 332 and the container seal 333, even when the toner container 32 swings or falls, the movement of the container shutter 332 can be adjusted. Furthermore, because a contact compaction with the container seal 333 is maintained, a difference is not generated. Therefore, toner leakage can hardly occur.
[0362] The toner container 32 illustrated in figure 36 to figure 41 (seventh to twelfth embodiment) relates to an invention for using a space between the end of the cylindrical container opening 33a and the receiving opening 331. This space is originally provided for carrying out an invention for housing the nozzle plug 612 and the nozzle plug spring 613 in a closely contacted state when the toner container is attached to the toner replacement device 60, to prevent dispersion of toner and to reduce the size. Therefore, the extraordinary feature of the invention described in connection with Fig. 36 to Fig. 41 is the use of the same space in the coupled state between the toner container 32 and the lid 370 when the toner container 32 is just stored. Thirteenth Achievement
[0363] Explanation of bolting of the nozzle receiver 330 will be made with respect to the container body 33.
[0364] The toner container 32 of the first to twelfth embodiments explained above with reference to figure 11 etc. is configured such that toner is filled into the container body 33 through the cylindrical container opening 33a, and thereafter, the nozzle receiver 330 is mounted in the cylindrical container opening 33a of the container body 33.
[0365] Therefore, if the nozzle receiver 330 is separated from the container body 33 by releasing the snap fit and the container body 33 is refilled with toner, all members can be reused. Furthermore, by decoupling the nozzle receiver 330 from the container body 33, it is possible to easily disassemble and classify the parts, which allows the recycling of materials.
[0366] An example configuration for attaching the nozzle receiver 330 to the container body 33 by threading will be explained below.
[0367] Figure 42 is an explanatory perspective view of the container shutter holder 340 used in the nozzle receiver 330 secured to the container body 33 by screwing. In the container plug holder 340, shown in Figure 42, male screws 337c are formed in the outer surface of the nozzle receiver attachment portion 337. A male thread groove (not shown) for screwing to male screws 337c is formed in the surface. cylindrical container opening container body 33 of the toner container 32 using container stopper bracket 340 illustrated in Fig. 42 .
[0368] In the nozzle receiver 330 using the container plug holder 340 illustrated in Figure 42, screwing to the container body 33 is performed while the container seal 333 and the container plug 332 are held by the container plug holder 340 The toner container 32, including the container plug holder 340 illustrated in Fig. 42 has the same configuration as the toner container 32 discussed above with reference to Fig. 11 etc., except that the nozzle receiver 330 is attached. to the container body 33 by screwing.
[0369] In the toner container 32 explained above with reference to figure 11, etc., the cylindrical container opening 33a for filling toner is closed by the snap-mounted nozzle receiver 330. Consequently, in some cases, it is difficult to separate the nozzle receiver 330 from the container body 33 after use and recycling may become difficult. Recycling here includes replacement, in which the toner container 32 is refilled with toner in order to be reused, and material recycling, in which the toner container 32 is disassembled and the materials are sorted.
[0370] To deal with the above issue, on the toner container 32 using the container shutter holder 340 illustrated in figure 42, the nozzle receiver 330 is rotated in the direction of arrow A in figure 42, while the toner container 32 is being corrected. Alternatively, the toner container 32 is rotated in the opposite direction of the arrow A direction in Figure 42, while the nozzle receiver 330 is fixed. Due to the rotation, the thread between the nozzle receiver 330 and the container body 33 is released and the nozzle receiver 330 can be easily removed from the container body 33 after use. Therefore, the nozzle receiver 330 closing the opening of the cylindrical container opening 33a being a toner filling opening can be easily separated from the container body. Therefore, with the toner container 32 using the container plug holder 340 illustrated in Fig. 42, it is possible to easily realize such that the toner container 32 is refilled with toner so that it can be reused after use.
[0371] In addition, the nozzle receiver 330 includes the container closure holder 340, the container closure 332, the container seal 333, the container closure spring 336, and the like. Container closure holder 340 and container closure 332 are made of resin material, such as ABS, PS, or POM. In addition, container seal 333 is made of sponge or something similar, and container plug spring 336 is made of S-C (hard steel wire), SWP-A (piano string), SUS304 (hard steel wire), stainless steel for spring), or the like. In this way, the nozzle receiver 330 is formed from different materials. Therefore, because the nozzle receiver 330 can be easily removed from the container body 33 made of PET (polyethylene terephthalate) or the like, it is possible to easily carry out material recycling, wherein the toner container 32 is disassembled and the materials are Classified.
[0372] Furthermore, the present embodiment includes an invention as described below. Specifically, in the toner container 32 according to the embodiment, as illustrated in Figure 6, for example, the helical rib 302 is wound in such a way that, on the right side of the container body 33 seen from the front end of the container , the helical rib 302 is angled so that the upper end is located at the front end of the container relative to the lower end. Thus, by rotating the container body 33 such that the right side of the container body 33 seen from the front of the end container moves from top to bottom (rotates in the direction of arrow A in figure 6), the toner in the container body 33 can be transported to the front end of the container.
[0373] The nozzle receiver 330 rotates in the direction A in figure 6 together with the container body 33. However, because the container seal 333 slides against the driving nozzle 611, a friction force is generated between the container seal 333 and the drive nozzle 611 acts in a stop direction of rotation. An example will be explained below that the winding direction of the 337c plug screws differs from the direction illustrated in figure 42. In this case, the winding direction of the 337c plug screws becomes the same as the direction of the helical rib 302. That is, the 337c screws The right side males of the nozzle receiver attachment portion 337 is angled such that the upper end is on that side with respect to the lower end viewed from the front end of the container (a screw direction on the right). In this way, if the direction of winding of the plug screws 337c differs from the direction shown in Fig. 42, in the direction of the container body 33 of rotation (Arrow A direction in Fig. 6) corresponds to the direction of releasing the thread from the container body.
[0374] On the other hand, in the toner container 32 using the container shutter holder 340 illustrated in Figure 42, the winding direction of the male screws 337c is opposite to the winding direction of the helical rib 302. Specifically, in the toner container 32 according to the embodiment, as illustrated in Figure 42, the male screws 337c are formed such that the nozzle receiver 330 becomes a left-hand screw. Therefore, it is possible to avoid a situation where rotation of the container body 33 in the direction of arrow A acts to release the thread between the container body 33 and the nozzle receiver 330.
[0375] Inventions on a positional relationship between the emptying wall surface 304f and the shutter rear end support portion 335 in the container body 33 will be explained below.
[0376] First, a problem is explained below. When the container body 33 is properly filled with toner only after the toner container 32 is attached to the toner reset device 60, for example, the toner is continuously supplied to the nozzle opening 610 of the drive nozzle 611, as if excess toner. Accordingly, by rotating the shutter side support portions 335a so as to traverse an area above the nozzle opening 610 to relieve excess toner and controlling the amount of rotation of the drive screw 614 through intermittent operation, it is possible replace developing device 50 with a desired amount of toner.
[0377] Incidentally, if the amount of toner in the container body 33 is reduced, due to the use, over time, the rate of the amount of toner slipped from an interval between the end of the emptying portion 304 on the side of the center of rotation and the driving nozzle 611 the amount of toner flowing from the emptying portion 304 of the nozzle opening 610 increases. Therefore, the amount of toner refilled to the developing device 50 is reduced. If the amount of toner refilled into the developing device 50 is reduced, the toner density of the developer G in the developing device 50 becomes unstable. Finally, the imaging apparatus can alert the end of toner and it becomes necessary to replace the toner container 32 although a large amount of toner remains in the toner container. In this state, the remaining toner amount in the toner container 32 at the time of replacement becomes big, which is a problem.
[0378] Figure 43 is a front explanatory view of the container body 33 fixed with the nozzle receiver 330, taken in a direction perpendicular to the axis of rotation, when the position in the direction of the axis of rotation is located in the position of the portion of emptying 304.
[0379] The present embodiment includes an invention as described below. Specifically, as illustrated in Fig. 43, in the toner container 32, the outer surfaces of the plug side support portions 335a confront the inner wall surface of the container body 33 on the upstream side of the emptying portion 304 in the direction of rotation A of the container body 33, when the nozzle receiver 330 is secured to the container body 33. More specifically, the outer surface of the plug side support portions 335a faces the upstream side of the inner wall surface of the container. which is divided by the convex surface 304h, which is a crest of an increasing portion into the container body 33, to the upstream and downstream sides. With this configuration, the emptying wall surface 304f, which is an inner wall surface of the downstream side in the direction of rotation A, between the inner wall surfaces, divided by the convex surface 304h of the container body 33, can be located above the space between the side support portions 335b, together with the rotation of the container body 33. The nozzle opening 610 is always open, face up. Therefore, when the emptying portion 304 is located on the upper side together with the rotation of the toner container 32, the toner collected by scooping portion 304 can pass through the space 335b between the supporting side portions and be supplied to the opening of nozzle 610.
[0380] Furthermore, as illustrated in Figure 43, a downstream facet 335c, which is an aspect of the shutter side support portions 335a on the downstream side in the direction of rotation, is disposed near the protruding convex surface 304h to the center of rotation of the container body 33. Therefore, the toner which has flowed along the void wall surface 304f falls onto the downstream facet 335c jumps out, and therefore is supplied to the nozzle opening 610. words, downstream facet 335c has a bonding function to pass toner received from emptying wall surface 304f to nozzle opening 610.
[0381] The function of connecting the common shutter side support portions 335a of the first to the twentieth embodiment will be explained below. Figure 9 is a cross-sectional view illustrating a relationship between the emptying portion 304 and the receiving opening 331 of the common toner container 32 of the first to twentieth embodiments. Fig. 44 is an explanatory cross-sectional view of the container body 33, taken along EE in Fig. 9, in particular, taken at the end surface of a drive screw shaft bearing 614 at the front end of the drive nozzle. 611 in FIG. 9. Figures 45A and 45B are schematic functional cross-sectional views taken along EE. Specifically, Figure 45A is a functional schematic diagram of a comparative example to explain a configuration in which the shutter side support portions 335a do not function as a bridge. Fig. 45b is a functional schematic diagram of the configuration illustrated in Fig. 44, wherein the shutter side support portions 335a function as a bridge.
[0382] First, a problem is explained below. As described in Patent Document 6, when the amount of toner carried in the drive nozzle is controllable, and if the proper toner is present near the drive nozzle opening, it is possible to stably transmit the toner. However, if the amount of toner in the toner container is reduced, in some cases, the amount of toner transported may be reduced and the toner may not be transported stably. This is because, although it is possible to move the toner into the vicinity of the opening by the spiral rib disposed inside the toner container, the toner slips before it reaches the opening arranged in the driving nozzle, so that the amount of toner that enters the drive nozzle is reduced. If the amount of toner transported is reduced and the toner cannot be transported stably, the density of the developer toner in the developing device becomes unstable. Therefore, as explained above with reference to Fig. 43, replacement of the toner container becomes necessary. In this state, a large amount of toner remains in the container body, so the toner remaining amount of toner in the container at the time of replacement becomes large.
[0383] In figure 9, the driving nozzle 611 (carrying tube) is inserted into the nozzle receiver (member insertion nozzle) 330 in the container body 33. The nozzle opening (powder receiving opening) 610 of the nozzle of drive 611 inserted into nozzle receiver 330 is opened so that toner can be transmitted to the toner reset device.
[0384] A part of the emptying portion 304 overlaps the nozzle opening 610 in the longitudinal direction of the toner container 32, and some other part of the emptying portion 304 is the inner wall surface of the container body 33 on the side of the the rear end of the container with respect to the nozzle opening 610. In particular, the emptying portion 304 is formed from the convex surface 304h, which corresponds to a ridge of an ascending portion which is the inner wall of the container body 33 ascending to the interior of the container body 33, and the emptying wall surface 304f, which is a wall surface on the side downstream towards the container between the surfaces of the inner walls, divided by the rotation ridge (see figure 44).
[0385] As illustrated in figure 44, the ridge of the convex surface 304h has a moderate convex shape influenced by the blow molding applied to form the container body 33. In figure 9, etc., the convex surface 304h is illustrated by a curve for convenience so as to distinguish it from the void wall surface 304f. The emptying portion 304 is a region indicated by a grid in Figure 9 and is formed by a pair of tracks that connect the convex surface 304h and the inner cylindrical surface of the container body 33 in a symmetrical manner with respect to the point of o. container body axis 33. The cross-sectional rotation EE of the wall surface located upstream in the direction of rotation of the container between the surfaces of the inner walls divided by the ridge extends approximately in the same direction as the cross-sectional direction EE. Consequently, the surface of the wall appears thick in Figure 44, which is illustrated with a pair of shaded areas in the cylindrical shape of the container body 33. The convex surface 304h is provided in the same portion that appears thick.
[0386] In Fig. 44, the conduction nozzle 611 in tube form has the nozzle opening 610 which opens at the top of the conduction nozzle. Shutter side support portions 335a, as a pair, attached to the container body 33 are provided between the drive nozzle 611 and the convex surface 304h. The plug side support portions 335a rotate together with the void wall surface 304f along with the rotation of the container body 33. In the cross section EE (at the bearing end surface of the drive screw shaft 614 at the front end of drive nozzle 611), convex surface 304h of shutter side support portions 335a facing each other. In this state, the emptying wall surface 304f, the facets 335c downstream of the shutter side support portions 335a, 611s and the rims of the nozzle opening 610 on the upstream side in the direction of rotation are arranged in this order, seen in starting from the downstream side in the direction of rotation of the container.
[0387] In the same way as the emptying function explained above with reference to Figure 43, even in the emptying portion 304 formed from the emptying wall surface 304f of the container body 33 in Figure 44, the outer surfaces of the side support portions shutter 335a and the downstream facets 335c function as a toner bridge of the toner passing from the emptying portion 304 of the nozzle opening 610, when the toner moves in the direction arrow T1 towards the nozzle opening 610 which is the drive nozzle opening 611 being the transport tube.
[0388] As illustrated in Figure 44, the inner diameters of the shutter side support portions 335a are larger than the outer diameter of the drive nozzle 611. Thus, it is possible to prevent the drive nozzle 611 from passing through a region in contact with the container seal 333 contact the inner surfaces of the plug side support portions 335a. As a result, a load is less likely to be applied when the drive nozzle 611 is inserted into the container body. Since the container seal 333 has an inner diameter smaller than the outer diameter of the drive nozzle 611 is formed over the nozzle receiver 330, it is possible to prevent toner in the container body 33 from leaking out of the body. of container 33 along the outer surface of the drive nozzle 611. Consequently it is possible to prevent the toner flowing outward than others into the passage of the toner transport connecting the container body 33 and the developing device 50 through the nozzle driving 611 areas.
[0389] The link function will be explained in detail below with reference to the schematic diagrams of figures 45A and 45B.
[0390] Figure 45A illustrates a flow of toner into the container body 33 when the shutter side support portions 335a are arranged so as not to provide bridge function. Toner collected by the emptying portion 304 along the circumferential direction of the container body, due to rotation of the container body 33 in the direction of arrow A in Figure 45A flows towards the nozzle opening 610 by gravity (an arrow T1 in Figure 45A). However, some of the toner flows outward from the gap between the drive nozzle 611 and the convex surface 304h (a convex that projects to the center of rotation of the void wall surface 304f) (arrow T2 in Fig. 45A) .
[0391] Specifically, Figure 45A illustrates a state, at the time when the void wall surface 304f is not fully brought up and the convex surface 304h is located near the 9:00 position on the clock face. This time, the rims 611s on the upstream side, the convex surface 304h of the void wall surface 304f, and the downstream facets of the shutter side support portions 335a are arranged in this order when viewed from the downstream side in the direction of the rotation of the container body 33. In this state, the facets of the shutter side support portions 335a in the middle are always delayed relative to the convex surface 304h of the drain wall surface 304f which tries to pass toner, so that the function of Toner binding is not obtained. Therefore, the replenishment speed may become unstable or the amount of toner remaining in the container body 33 at the time of replacement of the toner container 32 may be increased, which is a defect.
[0392] Figure 45B illustrates a flow of toner into the container body 33, including the shutter side support portions 335a that function as the bridge.
[0393] The same configuration as illustrated in Figure 45A where toner is applied collected by the emptying portion 304 along the circumferential direction of the container body, due to rotation of the container body 33 in the direction of arrow A in Figure 45A flows to nozzle opening 610 by gravity (Tl arrow in figure 45A). However, in the configuration illustrated in Fig. 45B, as the shutter side support portions 335a are arranged to fill the space between the drive nozzle 611 and the convex surface 304h (convex surface that protrudes into the center of rotation of the surface of emptying wall 304f). To realize this configuration, the downstream facets 335c of the plug side support portions 335a and the convex surface 304h of the emptying part 304 are arranged in this order when viewed from the downstream side in the direction of the rotating container body 33.
[0394] With this arrangement, it is possible to avoid the toner flow indicated by arrow T2 in figure 45A and allow the collected toner to enter the nozzle opening 610 efficiently. Therefore, it is possible to stabilize the replenishment speed, even when the amount of toner in the container body 33 is reduced, and to reduce the amount of toner remaining in the container body 33, at the time of replacement of the toner container 32. In addition Furthermore, because the amount of toner remaining in the container body 33 at the time of replacement can be reduced, an operating cost can be reduced to improve economic efficiency and the amount of waste toner to be disposed of can be reduced to reduce influence on the environment.
[0395] To fill the space between the drive nozzle 611 and the convex surface 304h, as described above, it is desirable that the shutter side support portions 335a and the convex surface 304h are attached to each other. However, while it is possible to avoid the toner flow indicated by T2, a slight clearance (approx. 0.3mm to 1mm) may be acceptable between the shutter side support portions 335a and the convex surface 304h, such as illustrated in convex surface 304h at the bottom in figure 45B. This is because the small space can be clogged with toner through operation performed with a large amount of toner at the beginning of replenishment and the toner can act as a seal. Furthermore, because the convex surface 304h is formed by blow molding where the dimensional accuracy is lower than injection molding, it is difficult to fully secure the plug side support portions 335a and the convex surface 304h. In view of productivity, it is preferable to form the structure with a slight clearance.
[0396] Figure 46 is a graph showing a relationship between an amount of toner remaining in the container and a replenishment speed (amount of toner supply per unit of time) according to the embodiment (the configuration illustrated in figures 44 and 45B) and the comparative example (the configuration illustrated in Fig. 45A).
[0397] It can be found from figure 46 that the replenishment speed is stable, even when the amount of toner remaining in the container decreases in the embodiment, the replenishment speed, but decreases when the amount of toner remaining in the container decreases in the comparative example. In the comparative example, in which a connecting element is not provided, it passes through toner (leakage) from the gap between the end of the emptying wall surface 304f on the center of rotation side being a part of the container body 33 and the nozzle driving 611. Therefore, the proper amount of toner can hardly be conveyed to the nozzle opening 610, when the amount of remaining toner decreases, so the feed amount to the nozzle opening 610 cannot be maintained and the speed replacement decreases.
[0398] The toner container 32 in the examples illustrated in figure 9, figure 43, figure 44, and figure 45B includes an invention as described below. Specifically, the void wall surface 304f is provided at two positions (side portions of the support plug 335a) of the container body, and the connecting elements are provided at two positions corresponding to the void wall surfaces 304f. It is effective to provide the same number of emptying for emptying wall surface 304f as the connecting components such that if the emptying wall surfaces 304f of the container body 33 are provided in three positions, the connecting components are also provided in three positions. Likewise, if the emptying wall surfaces of the container body 33 are provided in four or more positions, it is effective to provide the same number of connecting elements as the emptying wall surface 304f.
[0399] It is of course possible that only some limited portions of the plurality of shutter side support portions 335a are configured as the corresponding connecting element for the emptying wall surfaces 304f. For example, only one of the two plug rear end support portions 335 is configured as a connecting member and only one void wall surface 304f is formed on the container body 33, in accordance with the connecting element.
[0400] An example will be described further below that the container body 33 is formed as a cylindrical member made of resin (in the following, described as a container body to 1033 distinguish it from the container body of the other embodiments) and a portion emptying tubes are provided on a part of the conveyor inside the container body.
[0401] Figure 47A is a perspective view illustrating a configuration in which deflation ribs 304g corresponding to deflation wall surfaces 304f are integrated with the nozzle receiver 330 (described below as a nozzle receiver 1330). Fig. 47B is a cross-sectional view illustrating how the nozzle receiver 1330 illustrated in Fig. 47A is disposed on the container body 1033 relative to the drive nozzle 611. Fig. 47C is an explanatory side cross-sectional view of an entire toner container 1032 on which the nozzle receiver 1330 illustrated in Fig. 47A is mounted. Figure 47D is a perspective view of a container plug 1332 as a part of toner container 1032.
[0402] The nozzle receiver 1330 illustrated in Figures 47A to 47D include the deflation ribs 304g described above, which are integrated with a carrier blade holder 1330b of which the carrier blades 1302 are made of a flexible material such as a resin film, are fixed.
[0403] The nozzle receiver 1330 illustrated in Figures 47A to 47D includes a container seal 1333, a receiving opening 1331, a container plug 1332, and a container plug spring 1336. The container seal 1333 is a seal that it has a contact surface that confronts and contacts the nozzle plug flange 612a the nozzle plug 612 held by the drive nozzle 611 when the toner container 1032 is attached to the main body of the copier 500. The receiving opening 1331 is an opening into which the drive nozzle 611 is inserted. Container closure 1332 is a closure, which opens and closes receiving opening 1331. Container closure spring 1336 is a biasing member that biases container closure 1332 to a position where container closure 1332 closes. receipt opening 1331.
[0404] In the configuration illustrated in Figures 47A through 47D, the receiver includes a nozzle 1330 1330a outer surface of the receiver nozzle that is rotatably mounted to the inner surface 615a of the container configuration section of the main body of the copier 500. As illustrated in the figure 47D, container plug 1332 includes a contact section 1332a being in contact with drive nozzle 611 and includes plug supporting portions 1332b. The support plug extends from portions 1332b 1332a to the contact section in the longitudinal direction of the container body 1033, and includes hooked portions 1332c to prevent the container plug 1332 from exiting the receiver nozzle 1330 due to the pressure force applied by the container shutter spring 1336. Toner container 1032 is provided with container gear 1301 which is structured separately from container body 1033 and which is secured to nozzle receiver 1330 so as to impart motive force.
[0405] In this way, a flow structure including the emptying inner wall surfaces, and a space 1335b between the support side portions for flowing toner to the nozzle opening 610 can be integrated.
[0406] The toner container 1032 including the 304g emptying ribs will be described in detail below.
[0407] As illustrated in Fig. 47C, toner container 1032 includes a container front end cap 1034, container body 1033, a bottom cap 1035, and nozzle receiver 1330. 1034 is provided at the front end of toner container 1032 in adjoining direction relative to the main body of copier 500. Container body 1033 has an approximately cylindrical shape. Bottom cap 1035 is provided at the rear end of toner container 1032 in the fastening direction. The nozzle receiver 1330 is rotatably held by the cylindrical container body 1033.
[0408] A gear exposure hole (not shown), which is an opening similar to the gear exposure hole 34a, is disposed in the front end cap of the container 1034 so that the container gear 1301 is secured to the nozzle receiver 1330 can be exposed. Cylindrical container body 1033 holds nozzle receiver 1330 so that nozzle receiver 1330 can rotate. Container front end cap 1034 and bottom cap 1035 are secured to container body 1033 (by a well-known method, such as heat sealing or adhesive agent). The bottom cover 1035 includes a rear axle bearing portion 1035a, which supports one end of the carrier blade holder 1330b, and includes a gripper 1303, which a user can grip when the user turns the toner container 1032 off/on/off. for the main body of the copier 500.
[0409] A method for assembling the front end cap of the container 1034, the bottom cap 1035, and the nozzle receiver 1330 of the container body 1033 will be explained below.
[0410] The nozzle receiver 1330 is inserted from the rear end of the container body 1033 and is positioned to be rotatably supported by a front end bearing shaft 1036 disposed at the front end of the container body 1033. the positioning is performed such that one end of the carrying blade holder 1330b of the nozzle receiver 1330 is rotatably supported by the rear end shaft bearing 1035a, 1035a and the rear shaft bearing is secured to the container body 1033. Then Furthermore, the container gear 1301 is secured to the nozzle receiver 1330 on the front end side of the container. After the container gear 1 is attached, the container front end cap 1034 is attached to the container body 1033 so as to cover the container gear 1301 from the container front end side.
[0411] The attachment between the container body 1033 and the front end cap of the container 1034, the attachment between the container body 1033 and the bottom cap 1035, and the attachment between the receiver and the nozzle 1330 of the container gear 1301 can be suitably carried out using a well known method such as heat sealing or adhesive agent.
[0412] A configuration for toner lead from toner container 1032 to nozzle opening 610 will be explained below.
[0413] The emptying ribs 304g protrude so as to approach the inner surface of the container body 1033 so that the rib surfaces are continued from the downstream facets 1335c, which are on the downstream side towards rotation, of the shutter side support portions 1335a. The rib surfaces are bent once in half so as to resemble the curved surfaces. However, the configuration is not limited to this example, depending on the degree of compatibility with the toner. For example, simple planar reinforcements without bending can be used. Furthermore, as the deflation ribs 304g are located integrally with the space 1335b between the supporting side portions, it is possible to obtain the same bonding function and effect as obtained by firmly fixing the plug side support portions 335a and the surface. convex 304h to each other. Namely, the transport blades rotate together with the rotation of the receiving nozzle 1330, when the toner container 1032 is fixed to the main body of the imaging apparatus, so that the toner contained in the toner container 1032 is transmitted from the rear end to the front end where the nozzle receiver 1330 is disposed. Thereafter, the deflating ribs 304g receive the toner transmitted by the transport blades 1302, collecting the toner from the bottom up, along with rotation, and the toner flow to the nozzle opening 610, using the rib surfaces as sliders.
[0414] A configuration of attaching the nozzle receiver 330 to the container body 33 on the toner container 32 will be explained below as fourteenth to nineteenth embodiment. In Figures 48A, 49, 51B, 52B e, the container gear 301 is shown in roller form, omitting the gear teeth. Fourteenth Achievement
[0415] Figures 48A to 50B are explanatory diagrams of the toner container 32 according to the fourteenth embodiment. Figures 48A and 48B are explanatory perspective views illustrating a state where the nozzle receiver 330 is separated from the container body 33 of the toner container 32. Figure 49 is an explanatory perspective view of a front end of the toner container. toner 32 and the container fitting section 615 according to the fourteenth embodiment. Fig. 50A is a cross-sectional view of the vicinity of the front end of the toner container 32. Fig. 50B is an explanatory enlarged view of a region n illustrated in Fig. 50A. In Figures 48A to 50B, the container front end cap 34 is omitted. In Figures 48A to 49, the container plug 332 is omitted. In Fig. 50, the nozzle plug 612 is omitted.
[0416] The container body 33 of the toner container 32 according to the fourteenth embodiment is molded by a blow molding process, as explained above, in other embodiments. However, the accuracy in blow molding tends to be less than that of injection molding used in general resin molding. Consequently, in some cases, the roundness of the cylindrical cross section of the cylindrical container opening 33a with a part of the container body 33 being formed by blow molding may be low.
[0417] As described above, the cylindrical container opening 33a (the outer surface of the container in the radial direction of the front end opening 305) is slidably mounted to the inner surface 615a of the container configuration section 615. of the toner container 32 relative to the toner replacement device 60 penetrates in the planar direction perpendicular to the axis of rotation is determined. This time, if the roundness of the outer surface of the cylindrical container opening 33a which contributes to positioning is low, the position of the toner container 32 relative to the toner reset device 60 may be offset when the toner container rotates.
[0418] However, the nozzle receiver 330 is a general resin molded product formed by injection molding. Therefore, the nozzle receiver 330 can be molded more accurately than the container body 33, and the nozzle receiver attachment portion 337 being a part of the nozzle receiver 330 can be molded into a cylindrical shape with good roundness.
[0419] In the fourteenth embodiment, the outer diameter of the nozzle receiver attachment portion 337 of the nozzle receiver 330 is larger than the inner diameter of the cylindrical container opening 33a. With this configuration, the cylindrical outer surface of the cylindrical container opening 33a is adjusted so as to follow the nozzle receiver attachment portion 337 when the nozzle receiver 330 is attached to the container body 33 so that the roundness can be improved.
[0420] By improving the roundness of the outer surface of the cylindrical container opening 33a, the positioning accuracy of the toner container 32 relative to the toner reset device 60 can be improved.
[0421] If the roundness of the outer surface of the cylindrical container opening 33a is low, it is necessary to set the inner surface 615a of the container configuration section 615 to a larger size, taking a variation in shape into account. However, if the inner surface 615a is defined as a grater size, the freedom of displacement of the outer surface of the cylindrical container opening 33a relative to the inner surface 615a of the container shaping section 615 in the planar direction perpendicular to the axis of rotation increases , resulting in large backlash. In contrast, in the fourteenth embodiment, the circularity of the outer surface of the cylindrical container opening 33a can be improved and the inner surface 615a of the container configuration section 615 need not be adjusted to a larger size, so that the clearance can be reduced. With a reduction in clearance, the positioning accuracy of the toner container 32 relative to the toner replacement device 60 can be improved.
[0422] As illustrated in Figures 48A, 50A, and 50B, the nozzle receiver engaging lugs 3301 are provided at two positions on the outer surface of the nozzle receiver attachment portion 337 of the receiver 330. The two engaging lugs of nozzle receiver 3301 are disposed at positions 180° apart from one another in the circumferential direction of the outer surface, i.e. at positions opposite each other on the surface of the nozzle receiver attachment portion 337. of nozzle receiver 3301 have rectangular shapes extending in the circumferential direction, when viewed from the radial direction of the nozzle receiver attachment portion 337 which has a cylindrical shape. As illustrated in Fig. 48B, the nozzle receiver engaging lugs 3301 have trapezoidal shapes when viewed from the axial direction of the nozzle receiver attachment portion 337. The amount of boss (height) is approx. 0.5 mm from the surface of the nozzle receiver attachment portion 337. The tracks of the trapezoids are located on the downstream side in the direction of the container body 33. The opposite surfaces of rotation of the support tracks in the radial direction on the upstream side towards the rotating container body 33.
[0423] Meanwhile, two mating holes 3051 of the front end opening are provided in the cylindrical container opening 33a. The engaged holes 3051 of the front end opening are arranged at positions 180° apart from each other in the peripheral direction of the inner surface of the cylindrical container opening 33a, which is opposite each other on the inner surface of the cylindrical container opening 33a , such that the inner surface and the outer surface can communicate with each other. The engaged holes 3051 of the front end opening are elliptical holes that extend in the peripheral direction as viewed from the radial direction of the nozzle receiver attachment portion 337.
[0424] With this configuration, the nozzle receiver engaging lugs 3301 are engaged with the two mating holes 3051 of the front end opening, respectively, when the nozzle receiver 330 is secured to the container body 33. Due to the coupling, it is possible to prevent the nozzle receiver 330 coming out of the container body 33 and rotation relative to the container body 33.
[0425] Such a rotation preserver as described above is effective to maintain the relative positional relationship of the void wall surfaces 304f, the convex surface 304h, and the shutter side support portions 335a being the connecting members, in order to enable the toner binding function. The reasons why the nozzle receiver engaging lugs 3301 are formed in trapezoidal shapes in the axial direction will be described below.
[0426] Details will be explained below with reference to figure 48B. The nozzle receiver 330 can be easily removed from the container body 33 by rotating the nozzle receiver attachment portion 337 toward the slopes. This makes it possible to discharge or fill toner from or to the container body 33. Incidentally, when the container body 33 is fixed to the toner reset device for operation, because the radially opposite surfaces that are the tracks are located upstream of the easily rotating direction of the container body 33, the permanent surfaces receive a rotation force transmitted by the container gear 301 through the contact sections of the engaged holes 3051 of the front end opening. Specifically, the foot surfaces facing the slopes of the nozzle receiver engaging lugs 3301 pivot so as to be continuously engaged with the engaging holes 3051 of the front end opening. Therefore, the nozzle receiver 330 does not rotate with respect to the container body 33 during resetting, so that positional deviation can hardly occur. If the slopes of the trapezoids are located downstream in the direction of rotation, the tracks receive the rotation force, which can result in position deviation.
[0427] An annular seal external receiver 3302 is provided at a stage where the outer diameter of the nozzle receiver attachment portion 337 of the nozzle receiver 330 is reduced. The step is located opposite a step where the inner circumference of the cylindrical container opening 33a is reduced so that the sealing outer receiver 3302 is sandwiched between the two steps when the nozzle receiver 330 is attached to the container body 33 It is therefore possible to prevent the toner contained in the container body 33 from being poured through a gap between the outer surface of the nozzle receiver attachment portion 337 and the inner surface of the cylindrical container opening 33a.
[0428] In addition, the receiving outer seal 3302 is compressed by two steps. Therefore, when the nozzle receiver 330 is attached to the container body 33, a reset force of the externally compressed receiver sealing 3302 is applied so that the nozzle receiver 330 pushes against the container body 33. The reset force is received by contact (coupling) between the standing surfaces of nozzle receiver engagement protrusions 3301 and the inner surfaces of the engaged holes 3051 of the front end opening.
[0429] As described above, in the fourteenth embodiment, the cylindrical container opening 33a is adjusted so as to follow the nozzle receiver attachment portion 337 resulting in improved roundness.
[0430] The container body 33 including the cylindrical container opening 33a is made of PET (polyethylene terephthalate) and a thickness W1 of the cylindrical container opening 33a is set to 1.1mm. The nozzle receiver 330 including the nozzle receiver attachment portion 337 is made of PS (polystyrene) and a thickness W2 of the nozzle receiver attachment portion 337 is configured to 2mm. In this case, when a fit tolerance (the difference between the outer diameter of the nozzle receiver attachment portion 337 and the inner diameter of the cylindrical container opening 33a) was set to 0.01 mm to 0.1 mm, preferable results in terms of the positioning accuracy of the toner container 32 relative to the toner replacement device 60 and in terms of toner leak prevention performance.
[0431] In general, components are secured by snap fit. On the other hand, in the structure according to the fourteenth embodiment, a tolerance between the components can be increased. Consequently, productivity can be assured. In addition, a restoring force of the external seal receiver 3302 is received by coupling the nozzle receiver engagement lugs 3301 so that the adjustment tolerance of an extremely small value including the smallest value of 0.01 mm can be allowed . In addition, the nozzle receiver engagement lugs 3301 as rotation preservers. Furthermore, in the fitted portion, the shape of the cylindrical container opening 33a is adjusted. Thus, the function of fixing the positions of the components in the axial direction and the function of adjusting the shape of the cylindrical container opening 33a are separated. In the fourteenth embodiment, the nozzle receiver 330 is secured to the container body 33 using the nozzle receiver engaging lugs 3301. If the container body 33 and the nozzle receiver 330 are secured by the nozzle receiver engaging lugs 3301, the position of the nozzle receiver 330 relative to the container body 33 can be offset in the planar direction perpendicular to the axis of rotation of the toner container 32. By contrast, in the fourteenth embodiment, as the cylindrical container opening 33a is mounted by pressing by being adjusted in shape, it is possible to avoid the positioning deviation of the nozzle receiver 330 with respect to the container body 33 in the planar direction perpendicular to the axis of rotation of the toner container 32.
[0432] Thus, in the fourteenth embodiment, both the engagement of the nozzle receiver engagement lugs 3301 and snap fit are used to secure the container body 33 and the nozzle receiver 330. Upon engagement of the nozzle receiver engagement lugs nozzle receiver 3301, the compressed amount of the external receiver seal 3302 formed from a rubber packing or the like is determined. This contributes to the positioning of the toner container 32 in the direction of the axis of rotation. Incidentally, if the shape of the cylindrical container opening 33a is further adjusted by pressure to match the shape of the nozzle receiver attachment portion 337, the outer surface of the nozzle receiver attachment portion 337 and the inner surface of the opening of cylindrical vessel 33a are better fastened. This snap fit contributes to the positioning of the toner container 32 in the planar direction perpendicular to the axis of rotation. Fifteenth Achievement
[0433] A fifteenth embodiment is the same as the fourteenth embodiment in which the configuration illustrated in figures 48A to 50B is basically the case, but is different from the fourteenth embodiment in which the outer diameter of the receiver attachment portion of nozzle 337 of nozzle receiver 330 is smaller than the inside diameter of the cylindrical opening 33a to the container.
[0434] The cylindrical container opening 33a and the nozzle receiver fixing portion 337 are made of hard material because their dimensional accuracy must be ensured for coupling with the toner replacement device 60. Examples of material for the receiver of nozzle 330 having the nozzle receiver attachment portion 337 include PS (polystyrene). Examples of the material for the container body 33 with the cylindrical container opening 33a include PET (Polyethylene terephthalate). When the cylindrical container opening 33a and the nozzle receiver attachment portion 337 are secured together by snap fit, the outer surface of the nozzle receiver attachment portion 337 is hermetically sealed by the inner surface of the cylindrical container opening. 33rd. To improve the sealing performance between the inner surface of the cylindrical container opening 33a and the outer surface of the nozzle receiver attachment portion 337, it may be possible to increase the outer diameter of the nozzle receiver attachment portion 337 relative to the diameter. inside the cylindrical container opening 33a. However, if the outer diameter of the nozzle receiver attachment portion 337 is increased, although it is possible to adjust the shape of the cylindrical container opening 33a as in the toner container 32 of the fourteenth embodiment, a greater adjustment force is required at the time. of fixation. If the snapping force increases, the cylindrical container opening 33a and the nozzle receiver attachment portion 337 may be deformed or broken. Therefore, it becomes necessary to reduce the dimensional tolerance in the mounted portion between the cylindrical container opening 33a and the nozzle receiver attachment portion 337 and to accurately manage the process.
[0435] On the other hand, if the outer diameter of the nozzle receiver attachment portion 337 is reduced relative to the inner diameter of the cylindrical container opening 33a, a defect as described below may occur. Specifically, even when the engaged part is defined as a detachment preventer and the position in the direction of the axis of rotation is determined, the nozzle receiver attachment portion 337 of the nozzle receiver 330 moves up and down in the opening. of cylindrical container 33a within component tolerance. Therefore, it becomes difficult to seal the space between the cylindrical container opening 33a and the nozzle receiver attachment portion 337.
[0436] Therefore, in the fifteenth embodiment, the annular sealing outer receiver 3302 as a sealing element made of elastic material is used to seal the gap between the inner surface of the cylindrical container opening 33a and the outer surface of the attachment portion of nozzle receiver 337. Specifically, the sealing outer receiver 3302 is sandwiched between the cylindrical container opening 33a and the nozzle receiver attachment portion 337 such that the sealing outer receiver 3302 is compressed and elastically deformed to seal the opening. Since the sealing outer receiver 3302 is elastically deformed, a reset force acts in a direction where the nozzle receiver attachment portion 337 exits the cylindrical container opening 33a. However, in the fifteenth embodiment, the engaged portions between the nozzle receiver engaging lugs 3301 and the engaged holes 3051 of the front end opening prevent the nozzle receiver securing portion 337 from moving out of the nozzle opening. cylindrical vessel 33a. Therefore, the position of the receiver nozzle 330 relative to the container body 33 in the direction of the axis of rotation can be determined.
[0437] In addition, as the elastically deformed receiver outer seal 3302 seals the gap between the inner surface of the cylindrical container opening 33a and the outer surface of the nozzle receiver attachment portion 337, a reset force due to the deformation acts together of the zones of the inner surface and the outer surface in the circumferential direction. Due to the action of reset force, the position of the nozzle receiver attachment portion 337 in the planar direction perpendicular to the axis of rotation within the cylindrical container opening 33a is determined. Therefore, the position of the nozzle receiver 330 relative to the container body 33 in the planar direction perpendicular to the axis of rotation can be determined. The positioning is effective to maintain the relative positional relationship of the void wall surfaces 304f, the convex surface 304h, and the shutter side support portions 335a being the connecting components, in order to allow the toner to bridge function.
[0438] In the fifteenth embodiment, the sealed state is not obtained directly by the inner surface of the cylindrical container opening 33a and the outer surface of the nozzle receiver attachment portion 337. Consequently, a dimensional tolerance between the components can be increased. By increasing the dimensional tolerance, productivity can be improved. Furthermore, even when the nozzle receiver attachment portion 337 of the nozzle receiver 330 moves up and down within the cylindrical container opening 33a, because the sealed state is ensured by the external elastically deformed sealing receiver 3302, it is possible to prevent toner leakage.
[0439] In the fifteenth embodiment, the external seal of receiver 3302 being the sealing element is compressed by the inner surface being the sealing of the receiving surface of the cylindrical container opening 33a and the outer surface being the sealing of the receiving surface of the portion of nozzle receiver attachment 337 so that the sealed state is obtained. In addition, the nozzle receiver engaging lugs 3301 being engaging portions on the outer surface of the nozzle receiver securing portion 337 are engaged in the engaged holes 3051 of the front end opening to be the required parts of the cylindrical container opening 33a, so that the engaged state is obtained. The repulsive force (Restorative Force) applied by the 3302 compressed sealing external receiver is received by the coupling to prevent the nozzle receiver from coming out of the container body. Due to the repulsion force of the receiving outer seal 3302 and the detachment preserver performed by the coupling, the position of the toner container 32 in the direction of the axis direction can be determined. Therefore, it is possible to prevent the nozzle receiver 330 from coming out of the container body 33 due to the impact of an external force.
[0440] In addition, because the restoring force of the external seal receiver 3302 acts on the engaged holes 3051 of the front end opening of the cylindrical container opening 33a due to engagement with nozzle receiver engagement lugs 3301, the holes engaged 3051 of the front end opening need to have some strength. Therefore, it is desirable to use the force of a thick portion of the cylindrical container opening 33a for the engaged holes 3051 of the front end opening. In the fifteenth embodiment, as illustrated in Figures 50A and 50B, the male screw 309 for screwing the plug is provided at the front end of the container (at the top in Figures 50A and 50B) relative to the engaged holes 3051 of the front end opening, and the male screw 309 for screwing the cap is thicker than the other portion. By using the force of such a thick portion, it becomes possible to prevent the cylindrical container opening 33a from being separated due to the reset force of the sealing external receiver 3302.
[0441] In the fifteenth embodiment, a configuration is explained in which the receiving outer seal 3302 being the sealing element is provided on the outer surface of the nozzle receiver attachment portion 337 of the nozzle receiver 330. However, the sealing element can be provided on the inner surface of the cylindrical container opening 33a of the container body 33. sixteenth achievement
[0442] A first modification of the configuration, in which the position of the nozzle receiver 330 in relation to the container body 33 is determined using the deformation elastic of the sealing element that seals the gap between the container body 33 and the nozzle receiver 330 in the same manner as the fifteenth embodiment, a sixteenth embodiment will be explained below.
[0443] Figures 51A and 51B are explanatory diagrams of the toner container 32 according to the sixteenth embodiment. Specifically, Fig. 51A is an explanatory perspective view of the nozzle receiver 330 and Fig. 51B is an explanatory perspective view of the container body 33.
[0444] The toner container 32 according to the sixteenth embodiment illustrated in figures 51A and 51B include an invention as described below. Specifically, an insertion position regulator which regulates an insertion position in the direction of rotation when the nozzle receiver 330 is inserted into the container body 33 is provided at the container rear end of each of the nozzle receiver engaging lugs 3301 as the engaging portions and the mating holes 3051 of the front end opening as the engaging portions.
[0445] The formats applied in the sixteenth embodiment illustrated in figures 51A and 51B will be explained below. Nozzle receiver engaging protrusions 3301 are pentagonal in shape when viewed in the radial direction of nozzle receiver 330. The amount of protrusion (height) is approximately 0.5 mm from the surface of the nozzle receiver attachment portion 337 A corner portion 3301a of the surrounding protrusion is formed at the rear end of the container as the insertion position adjuster of the nozzle receiver engaging lugs 3301. The engaged port 3051 of the front end opening is a through hole in which a port is a hole elliptical extending in the peripheral direction of the cylindrical container opening 33a and the pentagonal hole described above overlap each other. As a position preserver insert of the engaged holes 3051 of the front end opening, an engaged hole lever portion 3051a (pentagonal hole lever portion) is formed at the rear end of the container.
[0446] The engaged hole 3051 of the front end opening, which is the engaged portion, is located inward (the side where toner is stored) in relation to the front end of the tubular front end opening 305 (the end of the opening). Therefore, when the nozzle receiver attachment portion 337 is inserted into the cylindrical container opening 33a together with the connection of the nozzle receiver 330 to the container body 33, the nozzle receiver engaging lugs 3301 are hidden by the cylindrical container opening 33a and go out of sight. Therefore, attachment is difficult in a predetermined position where the nozzle receiver engaging lugs 3301 are engaged with the engaged hole 3051 of the front end opening.
[0447] To deal with this, if a front end shape as an insertion position regulator is provided as in the sixteenth embodiment, it becomes possible to guide the nozzle receiver engaging lugs 3301 to a predetermined insertion position, even when the insertion position in the direction of rotation varies on a small scale. With the elliptical hole extending in the circumferential direction, you can easily see the nozzle receiver engagement protrusions 3301 in an offset position.
[0448] Furthermore, the advantageous effect as described below can be obtained by providing the insertion position regulator. Specifically, when the rotation unit is inlet and the container body 33 rotates, one of the engagement portion insertion position adjusters and the engaged portion are engaged with each other, so that the nozzle receiver 330 and the body of container 33 can be integrally rotated. Therefore, it is possible to prevent the nozzle receiver 330 from rotating and being offset relative to the container body 33 along with the rotation of the toner container 32. Seventeenth Achievement
[0449] A second configuration modification, in which the position of the nozzle receiver 330 relative to the container body 33 is determined using the elastic deformation of the sealing member that seals the gap between the container body 33 and the nozzle receiver 330 in the same way as the fifteenth embodiment, it will be explained below as a seventeenth embodiment.
[0450] Figures 52A and 52B are explanatory diagrams of the toner container 32 according to the seventeenth embodiment. Specifically, Fig. 52A is an explanatory perspective view of the nozzle receiver 330 and Fig. 52B is an explanatory perspective view of the container body 33.
[0451] The toner container 32 according to the seventeenth embodiment illustrated in figures 52A and 52B include an invention as described below. Specifically, a pair of positioning sections for determining the insertion position in the direction of rotation when the nozzle receiver 330 is inserted into the container body 33 and which overlaps at least one of the engaging portion and the engaging portion.
[0452] In the seventeenth embodiment illustrated in Figures 52A and 52B, the nozzle receiver engaging boss 3301, which is a boss extending in the peripheral direction, is provided as an engaging part of the nozzle receiver attachment portion 337. The concave receiver positioning portion 3303, which overlaps the nozzle receiver engaging protrusion 3301 at the center in the circumferential direction and extending in the direction of the axis of rotation of the container body 33, is provided as one of the pair of positioning sections for regulating the insertion position of the engagement portion to the engaged portion. The front end opening engaged hole 3051, which is an elliptical hole extending in the circumferential direction of the front end opening 305, is provided as the engaging portion of the cylindrical container opening 33a. A front end opening positioning rib 3052, which overlaps the engaged hole 3051 of the front end opening at the center in the circumferential direction and extending in the direction of the axis of rotation of the container body 33, is provided as the other of the pair of positioning sections for regulating the insertion position of the engagement portion to the engaged portion.
[0453] When the nozzle receiver attachment portion 337 is inserted into the cylindrical container opening 33a, together with the nozzle receiver attachment 330 of the container body 33, the cylindrical container opening 33a expands in the vicinity of the protrusions of nozzle receiver engagement 3301 protruding from the outer surface of the nozzle receiver attachment portion 337. Therefore, if positioning sections, such as a rib and a concave, are provided, in a position close to the engagement portion or the engaged portion so as not to overlap the engaging portion or the engaging portion, the cylindrical container opening 33a needs to be expanded in both the engaging portions and the positioning sections, which results in proper load increase.
[0454] In contrast, according to the seventeenth embodiment, the positioning ribs 3303 and 3052 formed of one rib and one concave as a pair are provided in the overlapping positions of both the nozzle receiver engaging lugs 3301 in the hole 3051 in the direction of the axis of rotation. In forming the positioning sections as described above, the front end opening positioning rib 3052 and the receiver positioning concave portion 3303 are coupled together in the engaging portion (nozzle receiver engaging boss 3301) which firmly adheres to the inner surface of the cylindrical container opening 33a at the time of attachment. Consequently, the part that expands in the cylindrical container opening 33a can be minimized to the engagement portion, the engagement position in the direction of rotation can be determined, and the nozzle receiver 330 can be prevented from rotating with respect to the container body. 33 with rotating toner container 32. Eighteenth Achievement
[0455] A third configuration modification, in which the position of the nozzle receiver 330 relative to the container body 33 is determined using the elastic deformation of the sealing member that seals the gap between the container body 33 and the nozzle receiver 330 in the same way as the fifteenth embodiment, a eighteenth embodiment will be explained below.
[0456] Figures 53A to 53C are explanatory diagram of the toner container 32 according to the eighteenth embodiment. Specifically, Figure 53A is an enlarged perspective view of the nozzle receiver attachment portion 337, Figure 53B is an enlarged perspective view of the nozzle receiver attachment portion 337, and Figure 53C is an enlarged cross-sectional view. from the vicinity of the front end of the toner container 32.
[0457] In the eighteenth embodiment, the receiving outer seal 3302 as a sealing element is provided on the outer surface of the nozzle receiver attachment portion 337. However, the sealing element may be provided on the inner surface of the container body 33 of the cylindrical container opening 33a.
[0458] Similarly to the fifteenth embodiment, the toner container 32 according to the eighteenth embodiment is configured such that an engaging portion is provided on the nozzle receiver 330 and an engaging portion to be engaged with the engaging part is provided on the cylindrical container opening 33a. To more reliably prevent the nozzle receiver 330 from exiting the toner container, it may be possible to increase the size of the engaging portion so that the engaged area with respect to the engaged hole can be increased. However, if the fitting portion provided in the nozzle receiver 330 is increased in size, insertion load becomes too large and the cylindrical container opening 33a may be deformed or damaged. In contrast, according to the eighteenth embodiment, an enveloping protrusion 3053 of the front end opening is provided on the container body 33, in addition to the nozzle receiver engaging lugs 3301 of the nozzle receiver 330 and a receiver coupled orifice 3304 is provided in the receiver nozzle 330 in addition to the engaging hole 3051 opening the front end of the cylindrical container opening 33a. Consequently, even when the amount of coupling in each portion is small, the total amount of coupling can be increased. Nineteenth Achievement
[0459] A fourth configuration modification, in which the position of the nozzle receiver 330 relative to the container body 33 is determined using the elastic deformation of the sealing member that seals the gap between the container body 33 and the nozzle receiver 330 in the same way that the fifteenth embodiment will be explained below as a nineteenth embodiment.
[0460] Figures 54A and 54B are explanatory diagrams of the toner container 32 according to the nineteenth embodiment. Specifically, Figure 54A is an enlarged perspective view of the cylindrical container opening 33a and Figure 54B is an enlarged perspective view of the nozzle receiver attachment portion 337.
[0461] The toner container 32 according to the embodiment illustrated in Figure 19 includes an invention positioning to determine the insertion position in rotation direction when the nozzle receiver 330 is inserted into the container body 33 is provided so as to overlap. if at least one of the engaging portion and the portion engaged on the toner container 32 according to the eighteenth embodiment.
[0462] When the nozzle receiver attachment portion 337 is inserted into the cylindrical container opening 33a, together with the connection of the nozzle receiver 330 to the container body 33, the cylindrical container opening 33a expands in the vicinity of the protrusions of nozzle receiver engagement 3301 on the outer surface of nozzle receiver attachment portion 337. Therefore, if positioning sections, such as a rib and a concave, are provided in position near the engagement portion or the mode engaged portion not to overlap the engaging portion or the engaged portion, the cylindrical container opening 33a needs to be expanded from both the engaging portion and the positioning section, which results in increased engagement load.
[0463] In contrast, according to the nineteenth embodiment, the positioning ribs and 3303 3052 formed of a rib and a concave portion as a pair are provided in the positions superimposed on the engaging lug 3053 and the engaged hole 3304 in the direction of the axis of rotation. In forming the positioning sections as described above, the front end opening positioning rib 3052 and the receiver positioning concave portion 3303 are coupled together in the engaging portion (nozzle receiver engaging boss 3301) which firmly adheres to the inner surface of the cylindrical container opening 33a at the time of attachment. Consequently, the part that expands in the cylindrical container opening 33a can be minimized to the engagement portion, the engagement position in the direction of rotation can be determined, and the nozzle receiver 330 can be prevented from rotating with respect to the container body. 33 with rotating toner container 32.
[0464] The toner container 32 according to the fourteenth to nineteenth embodiment includes an invention as described below. Specifically, the toner container 32 includes the container body 33 as a powder storage device which contains toner therein in powder form to be supplied to the toner replacement device 60 as a powder transport device. The container body 33 conducts toner contained therein from the rear end of the container to the front end of the container, where the opening is formed, in the direction of rotation by being rotated. The toner container 32 also includes the nozzle receiver 330 which serves as a nozzle inserter which has the receiving opening 331 which serves as a receiving member nozzle in which the drive nozzle 611 as a transport tube attached to the toner replacement device 60 is inserted and secured in the opening of the container body 33. In the toner container 32 configured as above, the nozzle receiver 330 includes the nozzle receiver engaging protrusion 3301 which is an engaging portion to be engaged with the engaged hole 3051 of the opening front end which is an engaged portion provided in the cylindrical container opening 33a having the opening. In addition, the toner container 32 includes the external sealing receiver 3302 serves as a sealing member which is disposed between the receiver 330 and the container body nozzle 33 when the nozzle receiver engaging protrusion 3301 is engaged with the orifice engaged 3051 of the front end opening and which seals the clearance between the receiver 330 and the mouth of the container body 33. Twentieth Achievement
[0465] A toner container 32 according to the twentieth embodiment will be explained below. A feature of the toner container 32 according to the embodiment resides in the twentieth one portion where the nozzle receiver 330 is pressure-fitted to the container body 33.
[0466] Figure 13 has been referred to in the embodiments explained above, but may also be referred to to explain the portion of the receiving opening 331 and the container body 33 adjusted to pressure; therefore, it is referred to in the explanation below. One of a Y region 1 and a Y region 2 in Figure 13 becomes the snap-mounted portion. The Y region 1 is the inner surface of the container 33 of the body where the container gear 301 is provided. The Y region 2 is the inner surface of the container body 33 where the lid hook portion 306 is provided.
[0467] The toner container 32 illustrated in Figure 13 includes an invention as described below. Specifically, the toner container 32 is a powder container, which contains toner as a powder developer and which includes the container stopper 332 and the nozzle receiver 330. The container stopper 332 serves as an open receiving opening near the member. /which opens and closes the receiving opening 331 which serves as a discharge opening through which toner powder is discharged from the container body 33 passes. The nozzle receiver 330 serves as an open/close support member to hold the container plug 332. The cylindrical container opening 33a is formed at the front end of the toner container 32, and the outer surface of the cylindrical portion of the opening. Cylindrical container 33a is slidably mounted to the cylindrical inner surface 615a (shaft bearing) of the container fitting section 615. The nozzle receiver 330 is secured to the inner surface of the container body 33 by snap fit, and the position of the primed fixed part in the direction of the axis of rotation is located at the rear end of the container with respect to the position where the outer surface of the cylindrical container opening 33a and the cylindrical inner surface of the container shaping slide section 615 against each other.
[0468] As illustrated in Figure 13, for example, the position of the front end of the receiver 330 and the position nozzle of the front end of the cylindrical container opening 33a in the direction of the axis of rotation are the same. Therefore, the nozzle receiver 330 can be press-mounted to the inner surface in the vicinity of the front end of the cylindrical container opening 33a. However, the vicinity of the front end of the cylindrical container opening 33a is fitted to the cylindrical inner surface 615a of the container configuration section 615. Consequently, if the pressure-fitted cylindrical container opening portion 33a expands and the outer diameter of the opening expands. cylindrical container 33a enlarges due to the press fit of the nozzle receiver 330, the cylindrical container opening 33a may not be press-fitted into the container configuration section 615, resulting in a failure in the connection between the toner container 32 and the device. reset toner 60. Even if the toner container can be fixed, the rotation torque of the toner container 32 may increase.
[0469] To avoid the above situation, it may be possible to estimate the amount of expansion of the cylindrical container opening 33a due to the snap fit, and define the outer diameter of the cylindrical container opening portion 33a, at the time of formation of the cylindrical container. 32 toner based on calculation. However, if the outer diameter of the cylindrical container opening 33a is defined, having the amount of expansion due to it, the following defect may occur on press mounted account. Specifically, it becomes necessary to define a large tolerance. If the amount of expansion is within a small tolerance range, a difference between the outer diameter of the cylindrical portion of cylindrical container opening 33a cylindrical inner surface 615a of the container shaping section 615, resulting in improper positioning increases.
[0470] As a configuration to avoid the above situation, in the toner container 32 according to the twentieth embodiment, the outer diameter of the vicinity of the front end of the nozzle receiver attachment portion 337 of the nozzle receiver 330 is defined as a slightly smaller size so the nozzle receiver attachment portion 337 can be mounted loosely, rather than snap-fitted, with the inner surface of the front end opening 305. In addition, like the snap-fit portion, the outer diameter of the nozzle receiver attachment portion 337 an irrelevant position connecting the container configuration section 615 and the container body 33 (a position where the fitting is not influenced) at the rear end of the container, rather than the front end of the container is defined as a size sufficient to allow adequate press fit with respect to the inside diameter of the container. The position may be irrelevant a position corresponding to a thickness portion of the container gear 301 (the Y region 1 in Figure 13) or it may be a position in which the inside diameter of the cylindrical container opening 33a is reduced so as to form one step and the thickness of the cylindrical container opening 33a is increased (Y region 2 in figure 13). In the position where the inner diameter is reduced so as to form a step (Y 2 the region in Figure 13), the lid hooked portion 306 formed by an annular rib, is also provided on the outer surface.
[0471] By forming a portion having a large outside diameter and serving as a pressure-adjusted portion at the rear end of the container relative to the front end of the nozzle receiver attachment portion 337 of the nozzle receiver 330 becomes if possible to avoid an increase in the outer diameter of the cylindrical container opening 33a in the portion of the container shaping section 615. Accordingly, adjusted to the pressure, it is possible to avoid a failure in the connection between the toner container 32 and the reset device. toner 60 or prevent an increase in the rotation torque of the toner container 32, due to an increase in the outer diameter of the cylindrical container opening 33a.
[0472] Furthermore, as the cylindrical container opening 33a remains in the same shape as in the preform generated by injection molding, the cylindrical container opening 33a can be molded with high precision. The portion in this position does not expand due to the snap fit of the nozzle receiver 330 and can be used as a positioning section and sliding section. Therefore, it is possible to maintain the good precision of injection molding, which allows to perform the positioning with greater precision and sliding with good performance.
[0473] The toner container 32 formed by press fit in the Y region 1 includes an invention as described below. Specifically, the nozzle receiver attachment portion 337 of the nozzle receiver nozzle receiver 330 made of pressure-matched resin is located to match the position of the inner surface of the container body 33, where the container gear 301 is provided. The strength of the part where the container gear 301 is provided is greater than the other portions of the container body 33 because a gear structure is formed to make a turn around the outer circumference in the direction perpendicular to the axis of rotation. Consequently, the portion is less likely to be deformed due to the press-fit. Furthermore, because the nozzle receiver attachment portion 337 can be firmly tightened, the nozzle receiver 330 is less likely to come off even over time. Therefore, the portion is preferable than the pressure mount portion.
[0474] Furthermore, the toner container 32 formed by snap-fitting in the Y region 2 includes an invention as described below. Specifically, the nozzle receiver attachment portion 337 of the pressure-adjusted nozzle receiver nozzle receiver 330 is located to match the position of the inner surface of the container body 33 where the lid hooked portion 306 is provided. . The strength of the part where the lid hooked portion 306 is disposed is greater than the other portions of the container body 33 because a rib structure is formed on the entire circumference in the direction perpendicular to the axis of rotation. Consequently, the portion is less susceptible to deformation due to pressure mounting. Furthermore, as the nozzle receiver attachment portion 337 can be firmly tightened, the nozzle receiver 330 is less likely to come off even over time. Therefore, the portion is preferable than the pressure mount portion.
[0475] A support structure for the identification tag 700 included in the common toner container 32 of the first through twentieth embodiments will be explained below.
[0476] Figure 55 is an explanatory perspective view of the connector 800 attached to the toner replacement device 60 and the front end of the toner container 32. As shown in Figure 55, the toner container 32 includes the container body 33 and the container front end cap 34, which is secured to the container body 33 to expose the cylindrical container opening 33a provided with the receiving opening 331 which serves as a discharge opening formed in the container body toner 33 Toner container 32 also includes identification tag 700 which serves as an information storage device attached to the front end of container front end cap 34 and a support structure 345 for securing identification tag 700.
[0477] The identification tag 700 according to embodiments is based on a communication contact system. Therefore, the connector 800 is disposed on the main body of the toner reset device 60 so as to confront the front end surface of the front end cap of the container 3.
[0478] Figure 56 is an explanatory perspective view of the front end of the toner container 32 and the connector 800, when the support structure 345 is disassembled. As illustrated in Fig. 56, a hole 701 for the positioning identification tag is formed over the identification tag 700. When the toner container 32 is attached to the toner reset device 60, a positioning pin 801 of the connector 800 is inserted into hole identification tag 701.
[0479] The support structure 345 includes a gripping portion 343 provided with retaining bases 358 for securing the identification tag 700, and includes an identification tag holder 344 that serves as a support for holding the identification tag 700 of such that the identification tag 700 is movable in the XZ direction in Fig. 56 and that it serves as a detachable cap element connected to the retaining portion 343. The identification tag 700 and the support structure 345 are disposed in the upper space obliquely right of the container front end cap 34 when the toner container 32 is viewed from the front of the end container along the axis of rotation. The support structure 345 is disposed on the front end cap of the container by utilizing the obliquely upper right space which becomes a dead space when the toner container 32 is arranged in parallel with the toner containers 32 of the other colors. This makes it possible to provide a compact sized toner replenishment device which allows the cylindrical toner containers 32 to be arranged adjacent to each other. In the obliquely upper left space of the container front end cap 34, the container gear 301 and the container drive gear 601 of the main body are arranged. To avoid interference between adjacent toner replacement systems, the toner containers are arranged to avoid interference between the identification tag 700, the scanning structure 345, the main body terminals 804, and the container drive gear. 601 of the main body of the toner replacement device 60.
[0480] Figure 57 is an explanatory perspective view of the front end of the toner container 32 and the connector 800, in which the identification tag 700 is temporarily attached to the identification tag holder 344. As illustrated in Fig. 57, a retaining portion 343 includes retaining bases 358 including four rectangular posts. Retaining bases 358 are formed on an identification tag attachment surface 357 on the front end of container front end cap 34, and maintain the surface of the identification tag backplate 700 where wiring is not disposed.
[0481] The identification tag holder 344 includes a frame 352 and support protrusions 353. The frame 352 is formed to enclose the outer sides of the detent bases 358 to prevent the identification mark from 700 from coming off when the frame is engaged with the retaining portion 343. The protrusions 353 of the support protrude with respect to the inner wall surface of the frame 352, so as to cover a region where no terminals are disposed on the surface of the identification tag 700. The frame 352 of the ID tag holder 344 is externally shaped large enough to house a rectangular ID tag 700, and holds the ID tag 700 so that the ID tag 700 can move to some extent in the XZ direction when the tag is placed. identification number 700 is in table 352.
[0482] The 345 support structure will be explained in detail below.
[0483] The frame 352 of the ID tag holder 344 is formed to be longer than the lengths of the retaining pads 358 in the Y axis direction in Fig. 57 (the height of the ID tag attaching surface 357). Therefore, when the identification tag 700 is attached to the retaining bases 358, the identification tag 700 is not affixed to the container front end cap 34. Furthermore, the identification tag 700 is affixed so as to maintain a clearance with respect to the frame 352 which surrounds the outer side of the identification tag 700 in the XZ direction. Furthermore, the identification tag 700 is affixed to maintain a small clearance with respect to the protrusions of the holder 353 of the identification tag holder 344. Therefore, the identification tag 700 is not separated from the container front end cap. 34, although the identification tag 700 is not affixed to the container front end cap 34. The identification tag 700 is made such that the identification tag 700 moves and rattles on the identification tag holder 344 when the toner container 32 is slightly shaken.
[0484] When the ID tag 700 is attached, as shown in figure 57, the ID tag 700 is engaged with a protrusion of the interior wall 351 of the ID tag holder 344 (see figure 56) and subsequently attached to the retaining bases 358 of retaining portion 343 in the temporary-attached state. This time, the outer portions of the detent bases 358 act as a guide for the identification tag holder 344. After the identification mark 700 is mounted on the retention bases 358, the identification tag 700 is affixed separate from the wall boss. internal 351 and placed over the front end surfaces of detent bases 358.
[0485] The mounting of ID tag holder 344 will be explained in detail below.
[0486] In the toner container 32 according to embodiments, the identification tag holder 344 is attached to the container front end cap 34 not by transformation, such as thermal caulking or fastening by a fastener, but by coupling with hooks.
[0487] As illustrated in Figure 56, ID tag holder 344 includes a top hook bracket 355, a bottom hook bracket 354, and a right side bracket hook 356 on a part top bracket 350, which is part of a bottom support 348, and a right side support part 349, respectively.
[0488] Around the identification tag attaching surface 357 to the container front end cap 34, three joined parts are formed in positions opposite the three hooks, i.e. the upper hook holder 355, the lower hook holder 354, and the right side support hook 356. Specifically, an upper clamping portion 359a is formed opposite the upper hook support 355 around the identification tag 357. A lower clamping portion 359b is formed opposite the lower support hook 354 around the identification tag attaching surface 357. A side attached portion 360 is formed opposite the right-hand support hook 356.
[0489] When the ID tag holder 344 is situated on the container front end cap 34, the three hooks (355, 354, 356) on the ID tag holder 344 are engaged with and secured to the three parts at attachment (359a, 359b, 360) on the container front end cap 34. Two of the three adjoining parts, in particular the attached upper part 359a and 359b of the attached lower part, are in the form of holes, and the remainder one, in particular, the attached side 360 is in the form of a hook.
[0490] The upper clamped part 359a and the lower clamped part 359b in the form of holes are defined using tracks at the front ends of the two hooks (the upper bracket 355 and the lower hook bracket hook 354) and using the elasticity of the two hooks . The side attached part 360 in the shape of a hook is defined using a slant on the front end of the right side hook bracket 356 and using an angled surface 360a of the side attached part 360.
[0491] With this configuration, as illustrated in Figure 57, the identification tag 700 is temporarily defined within the structure 352 of the ID tag holder 344 and the ID tag holder 344 is moved along the retaining bases 358 on the cover of container front end 34. Thus, hooks (355, 354, 356) formed on identification tag holder 344 can be engaged with joined portions (359a, 359b, 360) formed on container front end cap 34, so that the identification tag holder 344 can be secured to the container front end cap 34 by coupling between the hooks and the fasteners.
[0492] In the example described above with reference to figure 55 to figure 57, the portions engaged between the hooks (355, 354, 356) and the joined parts (359a, 359b, 360) are provided on an upper side, a lower side and a right side of the identification tag holder 344. However, the positions of the parts engaged with the identification tag holder 344 are not limited to a combination of the upper side, underside and the right side. The ordered parts can be supplied only on the upper and lower side, on the left and right side only, or on the entire upper side, lower side, left side, and right side of the support identification label 344. The positions and number of parts requested are not limited by achievements.
[0493] As described above, in the embodiments, a method of engagement using hooks is explained. However, in some cases, it may be possible to affix the tag holder to the identification 344 of the container front end cap 34 by means of processing such as thermal caulking or fastening by a fastener. For other examples, the identification tag holder 344 may need to be more firmly mounted or a tool to rewrite (rewrite) the identification mark without separating it from the container front end cap 34 may be available.
[0494] Referring to Fig. 58A to Fig. 63, the identification tag 700 that serves as an information storage device included in the toner container 32 according to embodiments will be explained.
[0495] In the explanation below, "an approximately rectangular metal plate" includes both a plate Consequently, "the approximately rectangular metal plate" includes plates obtained by chamfering all or some of the corners of a rectangular metal plate, formed into plates in an R form and the like.
[0496] Figures 58A to 58C are three drawing views of the identification tag 700. Figure 58A is a front view of the identification tag 700 800 seen from the side of the connector. Fig. 58B is a side view of the identification tag 700 viewed in a direction perpendicular to the direction of attachment (in the obliquely upper right direction in Fig. 55). Fig. 58C is an end view of identification tag 700 viewed from container front end cap 34.
[0497] Figure 59 is a perspective view of the ID tag 700, the ID tag holder 344, the connector 800 and, in particular, illustrates a relative positional relationship of the three members (700, 344, 800). In Fig. 59, the upper hook support 355 and the lower hook support 354 shown in Fig. 56 and Fig. 57 are omitted.
[0498] Figure 60 is a perspective view illustrating a state in which the identification tag 700 is * engaged with the connector 800. Figures 61A and 61B are circuit diagrams of an electrical circuit of the identification tag 700 and a connector 800 electrical circuit.
[0499] Figure 62A is a front view of ID tag 700 in possession of connector 800. Figure 62B is a front view of ID tag 700 rotated around ID tag hole 701 that is used for positioning. Fig. 63 is a diagram illustrating the identification tag 700 in contact with probes 901 of a driving inspection device 900 in a test process during manufacturing in a factory.
[0500] In the ID tag 700 according to embodiments, only one ID tag hole 701 is formed on a substrate 702, and the ID tag hole 701 is disposed between two of a plurality of metal blocks 710 (710a, 710b, 710c) of rectangular formed metal plates.
[0501] As illustrated in Figure 55, in the toner container 32 according to embodiments, the rectangular identification tag 700 is arranged such that the long side is slanted rather than being parallel to the vertical direction. Consequently, the vertical direction of the identification tag 700 to be disposed on the toner container 32 does not coincide with the longitudinal direction of the identification tag 700. However, hereafter, for convenience of explanation, in the direction parallel to the longer side of the tag of identification tag 700 (the direction of the Z' axis in Fig. 58A) is referred to as a vertical direction tag and the direction parallel to the short side of the identification tag 700 (the direction of X axis in Fig. 58A) is described as a direction mark. horizontal. The same applies for connector 800 which is angled relative to toner replacement device 60.
[0502] As illustrated in Figures 58A to 58C, to the ID tag 700 serving as an information storage device according to embodiments, the ID tag hole 701 is formed in a vertical position above the center of gravity of substrate 702 in the label vertical direction. A ground terminal 703 for earthing (earth), which is formed from a metal terminal, is installed on the inner surface of the ID tag hole 701 and around the ID tag hole 701. As illustrated in the figures 58A to 58C, the ground terminal 703 on the front surface of the substrate 702 of the embodiments is formed so that two projections of the ground terminals 705 extend in the tag horizontal direction relative to the circular ring portion.
[0503] A rectangular metal block 710 (the first metal block 710a) is disposed above the identification tag hole 701 in the vertical direction of the tag. In addition, two metal blocks 710 (the second metal block 710b and the third metal block 710c) are disposed below the identification tag hole 701 in the tag vertical direction.
[0504] In addition, as illustrated in Figure 58C, a shield 720 that is made of a resin material, such as a hemispherical epoxy, and that has an information storage section (not shown) covers and protects is formed on the surface. Back surface of substrate 702. In ID tag 700, ID tag hole 701 is disposed above shield 720, which is the largest and heaviest component provided on the back surface because it houses an information storage section, such as a IC (integrated circuit), in the vertical direction of the label. Consequently, as described above, it is possible to realize the positional relationship, wherein the identification tag hole 701 is located vertically above the center of gravity of the identification tag 700 in the tag vertical direction. The arrangement of the ID tag hole 701 depends on the shape of the substrate 702 or the configuration or arrangement of the back surface, such as shield 720.
[0505] Specifically, as illustrated in Fig. 62A, the identification tag 700 according to the embodiments is formed such that the center position of the identification tag hole 701 is located at a distance Za above the center of gravity of the 700 identification tag in the vertical direction tag.
[0506] As illustrated in Figure 59, connector 800 includes a connector body 805 which is a hollow housing made of resin, and positioning pin 801 (positioning boss), which is a hollow cylinder with a conical tip that is arranged in the body of the connector 805 so as to be in the horizontal direction. A main body ground terminal 802 is disposed over the positioning pin 801. The main body ground terminal 802 is a plate shaped (or linearly shaped) metal member, a portion of which is housed in the hollow section of the positioning pin 801 integrated with connector body 805. The curved portion of earth terminal 802 is exposed from a slit-shaped opening formed on a portion of the hollow cylinder periphery so as to protrude from the surface cylindrical exterior of the positioning pin 801. One of the terminals 804 of the main body is installed vertically above the positioning pin 801 (the ground terminal of the main body 802) in the vertical direction of labels, and two of the terminals 804 of the main body are installed. vertically below the 801 positioning pin in the label vertical direction. The 804 terminals of the main body are metallic members in sheet form (or linear form).
[0507] A pair of ribs is provided on the right and left sides of the positioning pin 801 on the tag in the horizontal direction of the lower body of connector 805 such that the inner tapered surfaces of the ribs confront each other. In addition, balance preservers 803 serving as a pair of regulators are provided so as to confront the underside of both sides of the ID tag 700 below the center of the ID tag hole 701 in the tag vertical direction.
[0508] When the identification tag holder 344 is attached to the container front end cap 34 of the toner container 32 and the toner container 32 is attached to the toner reset device 60, the identification tag holder 344 is located between connector 800 and ID tag 700. In this state, ID tag holder 344 holds ID tag 700 so that ID tag 700 can move (so that allowable clearance can be determined ).
[0509] As illustrated in Figure 59, on the ID tag holder 344, the holder protrusions 353 are provided on the bottom holder 348, a left side holder 342, and the right side holder part 349, respectively. . The three detent protrusions 353 provided on the bottom bracket 348, the left side bracket 342, and the right side bracket portion 349 can prevent the ID tag 700 from exiting the ID tag bracket 344 toward the connector 800.
[0510] A support hole 347 is formed in the end of the ID tag holder 344 on the side of the connector 800 (a wall surface, including the support protrusions 353). The support hole 347 is shaped such that a large portion of the end of the identification tag holder 344 is on the side of the connector 800, including the four terminal areas of the connector 800 (to three terminals 804 of the main body and a ground terminal of the main body 802) is opened. Furthermore, the support hole 347 of the identification tag holder 344 is formed in such a way that even an area corresponding to the preserving course 803 disposed on the connector 800 is open. When the toner container 32 is secured, the positioning pin 801 passes through the position of the support hole 347 and the opening of the balance preservers 803 subsequently passes through the position of the opening support hole 347 and enters the interior of the support. of identification tag 344.
[0511] The retaining feet 358 facing the rear surface of the ID tag 700 (on the side of the shield 720) are a part of the container front end cap 34. The four posts of the retaining feet 358 extend from from the waiting portion 343 to the side of the connector 800. The detent bases 358 press the vicinity of the four corners of the rectangular substrate 702 so as to avoid interference with the shield 720 affixed to the identification tag 700, and to avoid interference with the 803 balance preservers that are inserted when the 800 connector is attached.
[0512] However, when the positioning pin 801 is inserted into the ID tag hole 701 of the ID tag 700, the ID tag 700 is pressed to the rear end of the container by the ground terminal 802 or the terminals 804 of the positioning pin 801. This time, the four clamping bases 358 support the back surface of substrate 702, so that the state of contact between the terminals can be maintained.
[0513] Figure 60 is a schematic perspective view, representing a state in which the positioning of the connector 800 of the toner reset device 60 and the identification tag 700 is completed when the toner container 32 is attached to the toner device. replacement toner 60 (the main body of the copier 500). Specifically, Fig. 60 illustrates a state where the terminals on the main body side (the main body terminals 804 and the main body ground terminal 802) and the terminals on the identification tag side 700 (the metal block 710 and the ground terminal 703) are fixed to each other. In Fig. 60, for simplicity of understanding, the ID tag holder 344 and the three metal blocks 710 between the connector 800 and the ID tag 700 are omitted.
[0514] In the toner container 32 according to the embodiment, the cylindrical container opening 33a protrudes with respect to the container front end cap 34. When the unfixed toner container 32 is moved in the direction of arrow Q in figure 60 , in order to be attached to the toner replacement device 60, the outer surfaces of the cylindrical container opening 33a and the container fitting section 615 are interlocked with each other. Consequently, the position of the toner container 32 relative to the toner replacement device 60 in the direction of the axis of rotation is determined. Thereafter, when the toner container 32 is moved further in the direction of arrow Q in Fig. 60, a connection between the identification tag 700 and the connector 800 is initiated.
[0515] After the positioning of the toner container 32 in the direction perpendicular to the direction of the axis of rotation is determined the position of the front end cap of container 34 in the direction perpendicular to the direction of the axis of rotation is determined, the position of the identification tag 700 in the direction perpendicular to the direction of the axis of rotation is determined. Specifically, after the position of the cylindrical container opening 33a in the direction perpendicular to the direction of the axis of rotation is determined, the identification tag hole 701 of the identification tag 700 is coupled with the positioning pin 801 so as to be caught. by a tapered end of the positioning pin 801 of the connector 800. With this hitch, the positions of the identification tag 700 in the vertical direction and the marking tag in the horizontal direction are determined simultaneously. Specifically, the position of the identification tag 700 in the direction perpendicular to the direction of the axis of rotation is determined.
[0516] In addition, as illustrated in Figure 62A, the balance preservers 803 of connector 800 indicate the lower end portions that are horizontal on both sides of substrate 702 in the horizontal direction mark and that are located below the center of the 701 ID tag hole in the vertical tag direction. This time, even when the posture of the identification tag 700 is misaligned as illustrated in Figure 62B, when one of the tapered surfaces at the ends of the preserver rib-shaped balance 803 comes into contact with one of the edges, of a lower portion of the tag hole ID 701 rotates in a direction opposite to the contacted conical surface. Then, the rotation stops at a position where the identification tag 700 comes in contact with the two equally tapered surfaces, and the postural misalignment in the direction of rotation (rotation at the double arrow head in figure 62B) can be corrected (corrected to the state shown in figure 62A). As a result, the positioning of the identification tag 700 is completed.
[0517] This time, a portion of the ground terminal 703 of the ID tag 700 (the section corresponding to the inner surface of the ID tag hole 701) contacts the ground terminal 802 of the positioning pin 801 illustrated in the figure. 60, so that the identification tag 700 is fixed to ground (driving). After the ground is secured, as illustrated in Fig. 61A, the three metal blocks 710 (710a, 710b, 710c) of identification tag 700 are secured to the three terminals 804 of connector 800, respectively. Consequently, information can be transmitted between the identification tag 700 and the controller in the toner reset device 60 including the connector 800 (the controller 90 of the copier 500).
[0518] Thus, according to the embodiment, a positioning structure can be realized with greater precision and at lower costs based on several ideas described below (1) to (5). (1) Only one hole ID tag 701 is provided. Consequently, the costs of treating substrate 702 can be reduced. (2) The ground terminal of the main body 802 is integrally installed on the circumferential lateral surface of the positioning pin 801. Therefore, a distance between the positioning pin 801 and the ground terminal of the main body 802 can become substantially. zero, and the positioning accuracy of the ground terminal 703 with respect to the ground terminal of the main body 802 can be improved. (3) In the fully attached state, as illustrated in Figure 60, the positional relationship between the ID tag hole 701 and the curved sections of the terminals 804 of the main body is adjusted so that the center of the ID tag hole 701 coincides with the line connecting the vertices of curved sections (contact sections) of the three terminals 804 of connector 800. Therefore, it is possible to reduce a distance from the identification tag hole 701 that serves as a positioning point for the sections of contact of the terminals (the 804 terminals of the main body and the 710 metal blocks) in the horizontal direction label to almost 0mm. As a result, position accuracy can be improved when the three metal 710 blocks (710a, 710b, 710c) come into contact with the three 804 terminals of the main body. (4) A plurality of metal blocks 710 (710a, 710b, 710c) are disposed in a row, and the identification tag hole 701 is disposed in either of the two spaces formed between two of the three blocks. Therefore, it is possible to reduce a distance from the center of the identification tag hole 701 to the farthest metal block 710c (corresponding to the length of the arm of a pendulum) compared to an arrangement in which a positioning hole (or notch) ) is arranged on the top side or the outside underside of a row of 710 metal blocks (710a, 710b, 710c) in the vertical direction of labels. Specifically, when the positioning hole (or a notch) is arranged outside the line of three metal blocks 710 (710a, 710b, 710c), the length of the longer arm becomes the distance corresponding to the three metal blocks 710 from the center ( or the center of the notch). However, in the identification tag 700 according to the embodiment, the longest length of the arm can be reduced to a distance corresponding to two metal blocks 710. By reducing the length of the pendulum arm, even when the parallelism is farthest from the metal block 710c with respect to the terminals 804 of the main body is offset due to, for example, mass production, it is possible to minimize the offset. (5) When the toner container 32 is stored alone in some space, a foreign substance may enter the ID tag holder 344 and be trapped between the ID tag 700 and the holder protrusions 353 or the retaining feet 358, so that a positional deviation can be left. To deal with this problem, according to the embodiment, the positional relationship is effectively determined such that the ID tag hole 701 of the ID tag 700 is located above the center of gravity in the tag vertical direction. Therefore, when balance preservers 803 formed by a pair of ribs are inserted below the ID tag hole 701 is the center of rotation in the tag vertical direction, the ID tag 700 can be rotated. Specifically, the 700 ID tag comes in contact with the tapered surfaces of the 803 swing preserver (ribs) and is rotated so as to contact the two tapered surfaces equally. Therefore, it is possible to regulate the positional deviation and correct the posture. As a result, even when only a tag hole ID 701 is provided, the positioning accuracy of a plurality of metal blocks 710 (710a, 710b, 710c) relative to a plurality of terminals 804 of the main body can be improved therewith. time.
[0519] As described above (1) to (5), each of the five ideas can provide each of the beneficial functions and effects. Even if a low cost configuration is applied where the area size of the metal block 710 is made minimal, it is possible to greatly improve the accuracy of positioning a plurality of terminals (703, 710) on the identification tag 700, including the ground terminal 703 and a plurality of main body terminals (802, 804).
[0520] Other advantageous ideas and effects according to the embodiment will be explained below.
[0521] Each of the three metal blocks 710 (710a, 710b, 710c) will be described in detail below. Metal block 710a, which is at the highest level, receives a clock signal to control communication. The first metal block 710a employs a serial communication method that is low speed but low cost because of sequential data transfer and employs an I2C (integrated circuit) as a serial bus. The first metal block 710a forms a signal line for which a serial clock (SCL) is inserted when the serial line is attached to connector 800 of the toner replacement device 60. The first metal block 710a corresponds to a terminal to which a clock signal is input. However, because the clock signal flows in one direction, the first metal block 710a is highly likely to cause the identification tag 700 to break if a short circuit occurs between itself and Vdc (a power supply, the third metal block 710 ) to be described later, compared to the other terminals. Therefore, to avoid breaking the 700 ID tag, the first metal block 710a is located farthest away from Vcc. This is because the possibility of malfunction is reduced even if a short circuit occurs between the first metal block 710a and GND (ground terminal 703).
[0522] The second metal block 710b also employs a serial communication method, employing an I2C as a serial bus, and forms a signal line to which serial data (SDA) is input/output when the line signal is fixed. to connector 800 of the toner replacement device 60. The second block 710b has metallic bidirectional input/output mechanism, and, consequently, the possibility that the identification tag 700 breaks due to a short circuit less than the first metal block 710a employing a one-way input mechanism.
[0523] The third metal block 710c is a power input portion (Vdc), to which a voltage of 5V or 3.3V is input when it is attached to the 800 connector of the toner replacement device 60. risk of collapse of the entire device due to a short circuit between the power supply and the GND, the serial data input terminal (the second 710b metal block) is arranged between the GND (the 703 ground terminal) and the serial clock input terminal (the first metal block 710a). As illustrated in Figures 58A to 58C, the third metal block 710c that serves as the Vcc shield 720 overlaps the backside of the identification chip via substrate 702, and is located near an IC drive circuit (not shown ) on protector 720. Consequently, a short thick line can be obtained in the form of a line power supply, which allows stable power supply operations (ie reduction of malfunction due to noise).
[0524] Ideas regarding grounding are described below. In the operation of attaching the toner container 32, the ground terminal 703 of the identification tag 700 contacts the ground terminal 802 of the positioning pin 801 (the 800 connector). Then, the three metal blocks 710 (710a, 710b, 710c) of the identification tag 700 come into contact with the three terminals 804 of the connector 800. In other words, in the detachment operation of the toner container 32, the contact between the three metal blocks 710 (710a, 710b, 710c) of the identification tag 700 and the three terminals 804 of connector 800 is released. Thereafter, the contact between the ground terminal 703 of the identification tag 700 and the ground terminal 802 of the positioning pin 801 (the 800 connector) is released (separated).
[0525] Specifically, as illustrated in Fig. 61A, at connector 800, the contact start position of the ground terminal of the main body 802 is located closer to the identification tag 700, compared to the three terminals 804 of the terminal.
[0526] With this configuration, in the operation of attaching the toner container 32, the identification tag 700 is always attached to ground when the connection between the metal blocks 710 and the terminals 804 of the main body is initiated. In the detachment operation of the toner container 32, the identification tag 700 is always fixed to ground when the release of the connection between the metal blocks 710 and the terminals 804 of the main body is initiated (contact is released). Consequently it is possible to prevent the electrical circuit on the ID tag from floating electrically because of not being grounded. As a result, the 700 ID tag is less likely to be electrically damaged.
[0527] Specifically, when the electrical circuit in identification tag 700 is not grounded and becomes an electrically floating condition, the electrical circuit enters the state of being grounded with extremely large impedance. Consequently, even if only a slight static electricity generated by a separation or contact between the three metal blocks 710 and the three terminals 804 of the main body flows in the electrical circuit, a high voltage equal to the multiplication of the electrical current and impedance is generated. High voltage insulation causes damage inside the 700 ID tag IC so that the IC is broken.
[0528] Such a defect easily occurs when, as illustrated in Figure 61B, the start contact positions of the three terminals 804 and the ground terminal 802 on connector 800 are formed in the same positions with respect to the identification tag 700.
[0529] In contrast, according to the embodiment, the curved section of the ground terminal of the main body 802 exposed from the slot-shaped opening of the positioning pin 801 is arranged to be closer to the identification tag 700 with respect to the curved sections, with the majority of the protruding portions of the 804 terminals of the main body protruding towards the identification tag 700. Consequently, the ground is connected first at the moment of contact and the ground is released last at the moment of separation, so that the impedance of zero always becomes theoretical. As a result, even though static electricity runs in the electrical circuit, it is possible to avoid the occurrence of insulation breakage inside the IC.
[0530] In addition, the identification tag 700 according to the embodiment includes two earth terminal projections 705 disposed on a part of the outer circumference of the earth terminal 703, as explained above with reference to figures 58A to 58C.
[0531] By arrangement of the 705 ground terminal projections on the front surface of the 702 substrate of the 700 ID tag as described above, it is possible to easily perform the contact operation of an inspection probe in conducting the conduction inspection process (a inspection process whether or not the ID tag 700 is defective) at the time of manufacture in a factory. Specifically, as illustrated in Fig. 63, leading the ends of a plurality of probes 901 of the driving inspection device 900 is pressed down against the metal blocks 710 or the ground terminal 703 of the identification tag 700 on an inspection table . This time, because the 705 ground terminal projections of the 703 ground terminal have an area that can sufficiently come into contact with the front ends of the probes at 901, it is possible to prevent a conduction inspection failure caused by a failure in the contact of the probes. probes 901. In addition, inspection conduct is performed by pressing the front ends of probes 901 down against the ground terminal 703 (the ground terminal projections 705). Therefore, it is possible to improve the durability of 901 probes which are repeatedly used for inspection compared to a case where 901 probes are inserted into hole 701 in the identification tag of the inspection conduit. In addition, it is possible to avoid abrasion of the ID tag hole 701 of the ID tag 700 due to inspection conduct.
[0532] In a wedge-shaped excess space enlargement between the annular earth terminal 703 and the rectangular metal blocks 710, the components are arranged as follows. Specifically, the ground terminal projections 705 are contoured (the boundary line) in relation to the horizontal direction of the label. The boundary contacts the annular outer periphery of the earth terminal 703. The projections of the annular earth terminals 705 are arranged so as to be parallel to the longitudinal direction of the metal blocks 710 (710a, 710b, 710c). Therefore, the ground terminal projections 705 do not protrude in the vertical direction of the label and can be prevented from projecting into the right and left sliding areas of the substrate 702 which slides against the projections of the holder 353 (the label projection in the horizontal direction ). As a result, it is possible not to increase the size of substrate 702 and it is possible to obtain as many substrates 702 having the standard size as possible from a standard material having a nominal size, at the time of manufacture. Therefore, it is possible to reduce the initial cost increase of the ID tag 700.
[0533] In addition, the three 804 terminals of connector 800 are plate-shaped (or linear-shaped) metallic members.
[0534] The three terminals 804 are fixedly supported by the body of connector 805 such that one end of each of the terminals serves as a fixed end and the other end (the front end) of each of the terminals serves as a free end. . A curved section that curves relative to the identification tag 700 (the toner container 32) is formed on the front end of each of the three terminals 804. Specifically, the terminals 804 are bent like a knee (or boomerang) to the identification tag 700. The curved sections of the 804 terminals serve as contact sections with the 710 metal blocks.
[0535] In conjunction with the operation of attaching the toner container 32 to the toner supply device 60, the curved sections of the terminals 804 come into contact with approximate centers of the metal blocks 710 in the longitudinal direction (the label horizontal direction). When the affixing operation of the toner container 32 is still continued, the identification tag 700 approaches the connector 800, and the terminals 804 are displaced while being pressed and elastically deformed by the metal blocks 710 (such that the bending of the knee is straightened) such that the curved sections of the terminals 804 approach the side of the free end. Specifically, together with the toner container 32 clamping operation, the curved sections of the terminals 804 slide from the center to the free end side in the longitudinal direction (the horizontal label direction), while gradually increasing the contact pressure applied to the metal blocks 710.
[0536] With this configuration, it is possible to more reliably prevent a failure of contact between the terminals 804 of the main body, and the metal supports 710. Specifically, in some cases, the position of the container front end cap 34 (the metal blocks 710) relative to connector 800 (the 804 terminals of the main body) in the longitudinal direction (the tag horizontal direction) may be offset because of a variation in dimensional accuracy of related components or a variation in assembly accuracy (dimensional variation) . However, due to the above configuration, even when the longitudinal position of the container front end cap 34 relative to the connector 800 is offset, it is possible to more reliably prevent a failure of contact between the terminals 804 of the main body and the metal blocks 710.
[0537] As described above, in the toner container 32 according to embodiments, the contact type ID tag 700 (the information storage device) is held by retaining structure 345 of the ID tag holder 344. ID tag 700 is held by retaining structure 345 of ID tag holder 344 so that ID tag 700 can move about a virtual plane approximately perpendicular to the direction of movement (in the direction of arrow Q) along the which metal blocks (container terminals 710) approach (or come into contact with) the main body terminals 804. Therefore, even in the situations described below, a contact failure caused by a misplacement between the metal blocks 710 of the identification tag 700 and the terminals 804 of the connector 800 of the toner replacement device 60 can hardly occur. Specifically, even when the contact type identification tag 700 is mounted on the detachable toner container 32 attached to the toner replacement device 60 (the main body of the copier 500), contact failure can hardly occur.
[0538] Furthermore, according to embodiments, even when the contact type identification tag 700 is mounted on the detachable toner container 32 fixed to the toner replacement device 60, the identification tag 700 can hardly be damaged electrically. This is because the ground terminal 703 to be engaged with the ground terminal 802 on the positioning pin 801 of the connector 800 is formed over the identification tag hole 701 on the substrate 702 of the identification tag 700.
[0539] If toner fluidity is high, toner scattering due to fixing/unlocking of the replacement toner container easily occurs. This problem is addressed in the embodiments.
[0540] As indicators that indicate the fluidity toner, accelerated cohesion (%) and aerated bulk density (g/cm3) are known. The toner to be contained in the toner container 32 according to the embodiment may be as follows: toner with a volume average particle diameter of approximately 5.5 µm, accelerated cohesion of approximately 13%, and aerated bulk density of 0 .36 g/cm3 added with 3.3 (parts by weight) silica and 0.6 (parts by weight) titanium. This toner can be corrected by heating to 120°C and has excellent low temperature fixing ability.
[0541] Alternatively, it is possible to use toner with a volume mean particle diameter of approximately 4.5 µm, accelerated cohesion of approximately 18%, and aerated bulk density of 0.38 g/cm3, added with 2.3 silica (parts by weight) and titanium 0.7 (parts by weight). It is of course possible to use another toner instead of those illustrated above for example.
[0542] Toner can be manufactured using a known polymerization method or grinding method.
[0543] As a method for measuring a particle diameter distribution of a toner particle, a Coulter Counter method can be applied. As a measurement device based on this method, a Coulter Counter TA II or Coulter Multisizer II (each manufactured by Beckman Coulter, Inc.) can be applied.
[0544] Accelerated toner cohesion was measured by the Dust Tester (manufactured by Hosokawa Micron Corporation) in the test environment at a temperature of 24°C and humidity of 72%. Other conditions are listed in Table 1. [Table 1]


[0545] After measurement, toner cohesion is obtained according to the equation below.
[0546] % By weight of powder remaining in the upper screen x 1 (a)
[0547] % by weight of powder remaining in the middle screen x 0.6 (b)
[0548] % By weight of powder remaining in the lower screen x 0.2(c) Cohesion (%) = (a) + (b) + (c)
[0549] The measurement results are shown in Table 2 (unit:%) [Table 2]

[0550] According to the results presented in Table 2, the fluidity of toner D and E were determined as low.
[0551] Aerated bulk density is a value calculated by loosely filling a container with toner, flattening the toner, and dividing the mass by the interior volume of the container.
[0552] If toner fluidity is high, toner scattering is likely to occur. However, in the toner cartridge and the toner replacement device according to the present invention, toner is replenished to the toner replacement device inside the toner container. Consequently, while this setting is, of course, useful for toner with relatively low fluidity, the setting is more useful for toner with greater fluidity, because it can prevent toner scattering.
[0553] The above embodiments are explained by way of example only. The present invention can achieve various effects specific to each embodiment, as described below. (Delivery A)
[0554] A powder container, such as the toner container 32, removably attachable to an imaging apparatus, such as the copier 500, the powder container includes a container body, such as the container body 33 including a container opening, such as cylindrical container opening 33a, at a first end and containing imaging powder, such as toner; a conveyor, such as helical rib 302, disposed within the container body for conveying powder from a second end of the container body to the first end along a longitudinal direction of the container body; a nozzle receiver, such as the nozzle receiver 330, disposed in the container opening and including a nozzle receiving opening, such as the receiving opening 331, for receiving a powder conduction nozzle, such as the conduction nozzle. 611, of the imaging apparatus, the nozzle receiver for guiding the powder guiding nozzle into the container body; and an emptying portion, such as the emptying portion 304, collecting powder received from the conveyor with rotation of the emptying portion, to displace the powder from a powder receiving opening, such as the nozzle opening 610, conveying the nozzle powder. The nozzle receiving opening is disposed at the bottom of the interior of the container opening, such as the front end opening 305.
[0555] Consequently, as described in the above embodiments, as the nozzle receiving opening is arranged in the cylindrical inner bottom of the container opening, a portion of the edge of the container opening on the front end side of the container protrudes with respect to the member insertion nozzle edge where the nozzle receiving opening is formed. The bulge prevents leakage of leaked toner from the nozzle receiving opening when the driving nozzle is removed from the powder container. Furthermore, the contact element and the guiding element are housed in the inner space of the cylindrical opening of the container when the powder container is connected to the powder transport device. Consequently, it is possible to prevent the longitudinal dimensional increase of the powder transport device when the powder container is fixed. (Delivery B)
[0556] In the powder container according to embodiment A, an outer surface of the container opening the container body is a positioning section with respect to the imaging apparatus.
[0557] Therefore, as explained in the previous embodiments, it is possible to prevent powder, such as toner, to reach the outer surface of the container opening, allowing to improve the positioning accuracy of the powder container in relation to the transport device of the powder. (Delivery C)
[0558] In the powder container according to embodiment A, an axis of rotation of the container body is corresponding to the longitudinal direction, and a cylindrical outer surface of the container opening the container body includes a rotating axis section to be inserted in the receiver a rotating section of the imaging apparatus.
[0559] Therefore, as explained in the above embodiments, when powder is introduced a gap between the rotary shaft receiving section and the rotary shaft section forming a sliding part, a sliding load at the time of rotation and can increase the torque of container body rotation may increase. However, the present embodiment allows to prevent the powder from reaching the outer surface of the container opening. Consequently it is possible to prevent the powder from being introduced into the slip section and to avoid an increase in the slip load. As a result, it is possible to stabilize the sliding performance and avoid an increase in the rotation torque of the container body. (Delivery D)
[0560] In the powder container according to embodiment C, the outer surface of the container opening the container body is a positioning section with respect to the imaging apparatus.
[0561] Therefore, as explained in the previous embodiments, it is possible to stabilize the positioning accuracy of the powder container in relation to the powder transport device. (Delivery E)
[0562] In the powder container according to embodiment C or D, the nozzle receiver includes a fastening part, which has a screw, like the male screw 337c, on the outer circumference thereof, to secure the nozzle receiver to the container opening, in which a screwing screw direction is the same as a powder container rotation direction.
[0563] Therefore, as explained in the thirteenth embodiment above, it is possible to avoid a situation where the rotation of the container body causes to release the threading of the nozzle insert from the container body. (Delivery F)
[0564] In the powder container according to embodiment C or D, the nozzle receiver includes a securing portion, such as the nozzle receiver attachment portion 337, for securing the nozzle receiver to the container opening, a outer diameter of the fastening portion is greater than an inner diameter of the container opening, a protrusion, such as the nozzle receiver engaging protrusion 3301, formed in one of an outer surface of the fastening portion and an inner surface of the opening of container, while an engaging hole, such as the holes exerting 3051 of the front end opening, to be engaged with the protrusion is formed over the other on the outer surface of the fastening portion and the inner surface of the container opening, and the securing part is fitted to the container opening at a position where the protrusion and the hole are engaged.
[0565] Therefore, as explained in the fourteenth embodiment, the engagement between the protrusion and the engaged orifice can prevent the nozzle insert from coming out of the container body and rotation relative to the container body. Furthermore, since the outer diameter of the clamping portion is larger than the inner diameter of the container opening, the container opening can be adjusted to follow the clamping portion when the insert is secured to the mouth of the container body, resulting in improved roundness of the container opening. With the improvement of the roundness of the container opening, it is possible to improve the positioning accuracy of the powder container, such as the toner container 32, in relation to the powder driving device, such as the toner reset device 60. (Delivery G)
[0566] In the powder container according to embodiment C or D, the nozzle receiver includes a securing portion, such as the nozzle receiver securing portion 337, for securing the nozzle receiver to the container opening, a outer diameter of the fastening portion is smaller than an inner diameter of the container opening, a protrusion, such as the nozzle receiver engaging protrusion 3301, formed in one of an outer surface of the fastening portion and an inner surface of the opening of container, while an engaging hole, such as the engaged holes 3051 of the front end opening, to be engaged with the protrusion is formed over the other on the outer surface of the fastening portion and the inner surface of the container opening, a seal, such as external seal receiver 3302, is disposed in an opening between the fastening portion and the container body, and the nozzle receiver is mounted in the container opening, so that the seal is sealed. pressed and sandwiched between the clamping portion and the container body to a position where the protrusion and the orifice are engaged.
[0567] Therefore, as explained in the fifteenth embodiment, the engagement between the protrusion and the engaged hole can prevent the nozzle insert from coming out of the container body and rotation relative to the container body. Furthermore, the repulsive force applied by the seal and the release preserver realized by the fitting make it possible to determine the position of the powder container, such as the toner container 32, in the direction of the axis of rotation and prevent the nozzle insert element from coming. out of the container body, due to the impact of an external force. Also, as the seal is compressed into the seal, it is possible to prevent leakage of powder such as toner. (Delivery H)

[0569] Therefore, as explained in the twentieth embodiment, a section that serves as the axis of rotation of the container opening section does not expand due to the pressure joining of the clamping portion, so the section can be used as the positioning section or the sliding section. As a result, it is possible to maintain good precision in the molding of the container opening, allowing to carry out the positioning with greater precision and sliding with good performance. (Delivery I)
[0570] In the powder container according to embodiment H, a portion of the pressure-adjusted clamping portion is located so as to correspond to a position of a gear container transmitting a rotational force to the container body.
[0571] Therefore, as explained in the twentieth embodiment, the strength of the portion is greater than the other portions of the container body, so that the portion is less susceptible to deformation due to pressure joining. Furthermore, as the container body firmly grips the clamping portion, the nozzle insert, such as the nozzle receiver 330, is less likely to come loose even over time. (Fulfillment J)
[0572] In the powder container according to embodiment H, a portion of the pressure-adjusted clamping portion is located so as to correspond to a position where the container opening is thicker than the rotary shaft section.
[0573] Therefore, as explained in the twentieth embodiment, the strength of the portion is greater than the other portions, so that the portion is less likely to be deformed due to pressure joining. Furthermore, as the container body firmly grips the clamping portion, the nozzle insert, such as the nozzle receiver 330, is less likely to come loose even over time. (Fulfillment K)
[0574] In the powder container according to any one of embodiments A to J, the nozzle receiving opening is an orifice through an annular seal, and a closed space is formed around the driving nozzle and between the annular seal and the mouthpiece receiver.
[0575] Therefore, as explained in the previous embodiments, it is possible to prevent the annular seal from being trapped between the mouthpiece insert and the next open member /, such as the container plug 332. It is therefore possible to avoid a situation in which the nozzle receiving opening cannot be opened and closed due to the jammed annular seal. (Fulfillment L)

Therefore, the emptied powder can be efficiently inserted into the powder receiving opening. Consequently, it is possible to stabilize the replenishment rate even when the amount of powder in the container body is reduced. It is also possible to reduce the amount of toner remaining in the container body at the time of replacement of the powder container, such as the toner container 32. Furthermore, as the amount of powder remaining in the container body at the time of replacement, an operating cost can be reduced to improve economic efficiency and the amount of waste toner to be disposed of can be reduced to reduce the influence on the environment.
