TECHNICAL FIELD
[001] The present invention relates to an imaging apparatus such as a copy machine, a printer, a facsimile, or a multifunctional peripheral (MFP), a removable device and a developer container that are removably installed in the itself, and an information storage device installed in it. PRIOR TECHNIQUE
[002] Conventionally, in an imaging apparatus such as a copy machine, a technique of detachably installing a removable device such as a developer container (a toner bottle, a toner storage container, or a cartridge of ink) or a process cartridge in a body of the imaging apparatus is commonly used (eg, Patent Literature 1: JP Patent Application Open to the Public No. 2009-69417, Patent Literature 2: JP Patent Application Open to the Public No. 2006-209060, and Patent Literature 3: JP Patent Application Open to the Public No. 2002-196629).
[003] In the removable device, an information storage device (an information recording unit or a non-volatile memory) such as an ID chip storing information to be exchanged with the body of the imaging apparatus is installed. In a state where the removable device is affixed to the body of the imaging apparatus, information (for example, information such as the removable device's year, month and date of manufacture, a manufacturing batch number, or a color of toner, or a type of toner) stored in the information storage device is transmitted to a control unit of the body of the imaging apparatus, or information (information such as a history of the usage of the imaging apparatus) is transmitted from the body of the imaging apparatus to the information storage device, so that filling quality control of the body of the imaging apparatus and the removable device is carried out.
[004] Patent Literature 1 discloses a contact-type information storage device (an information recording unit). Specifically, in the contact-type information storage device (an ID chip), when the removable device (a toner storage container) is attached to the body of the imaging apparatus, a metal buffer (a terminal) enters in contact with a side terminal of the body of a connector installed in the body of the imaging apparatus. As a result, information can be exchanged between the information storage device of the removable device and the control unit (the body side information recording unit) of the imaging apparatus.
[005] In addition, a feed opening to let stored toner flow out is installed in the developer container. The opening needs to remain closed until loaded over a developing device in order to prevent toner from scattering or leaking.
[006] As a configuration to obtain the above will, a configuration in which a shutter is installed to open/close the opening installed in the developer container has been suggested. In addition, as a shutter configuration, a configuration has been suggested in which a flat plate-like shutter that is movable in a direction transverse to the toner and an outlet is installed (eg, Patent Literature 4: JP Patent Application Open to the Public on 2010-066638).
[007] However, the conventional techniques described above have the following problems.
[008] As a first problem the contact-type information storage device can be electrically damaged since an electrical circuit of the information storage device is not sufficiently grounded and thus becomes an electrically floating state when the removable device is fixed a or removed from the device body.
[009] The present invention is produced to solve the first problem described above and provides an information storage device, a removable device, a developer container, and an imaging apparatus in which electrical damage is difficult to occur in the device. of information storage even when the contact type information storage device is installed on the removable device removably installed in the body of the imaging apparatus.
[010] As a second problem, in the conventional contact type information storage device there can be a problem where the contact sections of the contact are misaligned (a contact failure) due to wrong positioning of the terminal (metal buffer) installed in the information storage device and in the terminal of the body of the imaging apparatus. Particularly when the terminal of the information storage device is small, the problem becomes important.
[011] The present invention is produced to solve the second problem described above and provides a removable device, a developer container and an imaging apparatus in which a contact failure caused by a positioning failure with the side terminal of the body of the connector of the body of the imaging apparatus is difficult to occur even when the contact-type information storage device is installed on the removable device detachably installed in the body of the imaging apparatus.
[012] A third problem is as follows. In recent years, toner having a small particle diameter is used in order to improve resolution. Improving a filter function to cope with toner usage can increase material or processing cost. That is, when a foaming material is used, it is necessary to prescribe mesh purity that does not let toner through, a so-called degree of foaming, but as mesh purity increases, flexibility tends to decrease. This tendency can be difficult to go along with shutter movement, and a sealing characteristic can get worse.
[013] The present invention has an improved invention of a shutter mechanism of the conventional toner feeding device. The improved invention provides a developer storage container and an imaging apparatus which has a configuration capable of releasably preventing toner from leaking from the developer storage container which is replaced by a fix/detach operation on a low cost. DISCLOSURE OF THE INVENTION
[014] In the present invention, a "process cartridge" is defined as a removable device that is configured such as at least one of a loading unit to load an image carrier, a developing unit (a developing device) to revealing a latent image formed on the image carrier, and a cleaning unit for cleaning the surface of the image carrier is integrally formed with the image carrier and is removably installed in the body of the image forming apparatus.
[015] Furthermore, in the present invention, a “almost rectangular metal plate” is defined to include the quasi-rectangular as well as the rectangular. Thus, the one in which all or part of an angular section of the rectangular metal plate is chamfered and the one in the form of R are also included in the “almost rectangular metal plate”.
[016] The effect of the present invention on the first problem is as follows. The present invention can provide an information storage device, a removable device, a developer container, and an imaging apparatus in which electrical damage is difficult to occur in the information storage device even when the information storage device of the contact type is installed in the removable device detachably installed in the imaging apparatus provided that a ground terminal engaged with a body side ground terminal formed in a projecting section of the body of the imaging apparatus is formed in a hole or in a notch formed in a substrate of the information storage device.
[017] The effect of the present invention on the second problem is as follows. In the present invention, the contact-type information storage device is held in a holding section to be movable in a virtual plane that is substantially orthogonal to a direction of movement in which a terminal approaches and comes into contact with a terminal. side of the body. Thus, the present invention can provide a removable device, a developer container, and an imaging apparatus in which a contact failure is caused by a mismatch with the side terminal of the connector body of the imaging apparatus body. Imaging is difficult to occur even when the contact-type information storage device is installed on the removable device detachably installed in the body of the imaging apparatus.
[018] The effect of the present invention on the third problem is as follows. According to the present invention, by causing an anchorage when striking against a rib on a circumferential edge of an ejection opening, adhesion can be ensured.
[019] Thus, by using a plug which is an existing component used to adhere/close the ejection port, a toner leakage from the ejection port can be reliably prevented without adding a special structure. BRIEF DESCRIPTION OF THE DRAWINGS

BEST MODE(S) FOR CARRYING OUT THE INVENTION
[021] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, like or corresponding parts are indicated by the same reference numerals, and thus a duplicate description thereof will be appropriately simplified or omitted. FIRST MODE
[022] A first embodiment of the present invention will be described in detail with reference to figures 1 to 30.
[023] Firstly, a configuration and operation of the entire imaging apparatus will be described.
[024] As illustrated in figure 1, in a toner container storage unit 70 above a body of the imaging apparatus 100, 32Y, 32M, 32C and 32K toner containers (developer containers) are installed so removable (replaceable) as four devices corresponding to their respective colors (yellow, magenta, cyan and black) (see also figures 3 to 5).
[025] An intermediate transfer unit 15 is arranged below the toner container storage unit 70. The 6Y, 6M, 6C and 6K imaging units corresponding to the respective colors (yellow, magenta, cyan and black) are arranged in-line to face an intermediate transfer belt 8 of the intermediate transfer unit 15.
[026] The 60Y, 60M, 60C and 60K toner feeding devices are arranged below the 32Y, 32M, 32C and 32K toner containers as the removable devices (developer containers) respectively. Toners stored in the 32Y, 32M, 32C and 32K toner containers are supplied (fed) into the developing devices of the 6Y, 6M, 6C and 6K imaging units by the 60Y, 60M, 60C and 6K toner feeding devices. 60K respectively.
[027] Referring to figure 2, the 6Y imaging unit corresponding to yellow includes a 1Y photosensitive drum, a 4Y charging unit arranged around the 1Y photosensitive drum, a 5Y developing device (a developing section), a 2Y cleaning unit, a neutralizing unit (not shown), or the like. An imaging process (a loading process, an exposure process, a developing process, a transfer process, and a cleaning process) is performed on the 1Y photosensitive drum, and thus a yellow image is formed on the 1Y photosensitive drum .
[028] The three remaining imaging units 6M, 6C and 6K have almost the same configuration as the 6Y imaging unit corresponding to yellow except that the toner colors used are different. Hereinafter, a description of the remaining three imaging units 6M, 6C and 6K will be appropriately omitted, and a description will be made in connection with the imaging unit 6Y corresponding to yellow.
[029] Referring to figure 2, the photosensitive drum 1Y is rotary driven clockwise in figure 2 by a drive motor (not shown). The surface of the 1Y photosensitive drum is uniformly loaded into the position of the 4Y loading unit (the loading process).
[030] Thereafter, the 1Y photosensitive drum surface reaches a position of laser light irradiation L emitted from an exposure unit 7 (see figure 1), and an electrostatic latent image corresponding to yellow is formed by scanning exposure in this position (the exposure process).
[031] Then, the surface of the 1Y photosensitive drum reaches the position facing the 5Y developing device, and the electrostatic latent image is developed in this position, so that a yellow toner image is formed (the development process).
[032] Then, the 1Y photosensitive drum surface reaches the position facing the intermediate transfer belt 8 and a 9Y primary transfer tilt roller, and the toner image on the 1Y photosensitive drum is transferred to the intermediate transfer belt 8 in this position (a primary transfer process). At this time, a slight amount of non-transfer toner remains in the 1Y photosensitive drum.
[033] After that, the surface of the 1Y photosensitive drum reaches the position facing the 2Y cleaning unit, and the non-transfer toner remaining in the 1Y photosensitive drum is mechanically collected by a 2a cleaning blade in this position (the cleaning process ).
[034] Finally, the surface of the 1Y photosensitive drum reaches the position facing the neutralization unit (not shown), and the residual potential in the 1Y photosensitive drum is removed in this position.
[035] Thus, a series of imaging processes performed on the 1Y photosensitive drum is finished.
[036] The imaging process described above is performed even in the other 6M, 6C and 6K imaging units in the same way as in the yellow 6Y imaging unit. That is, laser light L based on the image information is radiated from the exposure unit 7 arranged below the imaging units on the photosensitive drums of the imaging units 6M, 6C and 6K. Specifically, the exposure unit 7 emits laser light L from a light source and radiates laser light L on the photosensitive drum through a plurality of optical elements while sweeping laser light L through a polygonal mirror which is swivelly activated.
[037] After that, the toner images of the respective colors formed on the respective photosensitive drums through the developing process are transferred to the intermediate transfer belt 8 in an overlaid form. As a result, a color image is formed for the intermediate transfer belt 8.
[038] Referring to Figure 1, the intermediate transfer unit 15 includes the intermediate transfer belt 8, four primary transfer tilt rollers 9Y, 9M, 9C and 9K, a secondary transfer tilt roller 12, a plurality of tension rollers, an intermediate transfer cleaning unit, and the like. The intermediate transfer belt 8 is stretched over and supported by a plurality of roller members and moves incessantly in a direction of an arrow in Figure 1 as a roller member 12 is rotatably driven.
[039] The four primary transfer tilt rollers 9Y, 9M, 9C and 9K interpose the intermediate transfer belt 8 together with the 1Y, 1M, 1C and 1K photosensitive drums, respectively, to form primary transfer tongs. A reverse transfer skew on one toner polarity is applied to the 9Y, 9M, 9C and 9K primary transfer skew rollers.
[040] The intermediate transfer belt 8 moves in an arrow direction and sequentially passes through the primary transfer grippers of the 9Y, 9M, PC and 9K primary transfer tilt rollers. Toner images of the respective colors on the 1Y, 1M, 1C and 1K photosensitive drums are first transferred to the intermediate transfer belt 8 in a superimposed fashion.
[041] After this, the intermediate transfer belt 8 over which the toner images of the respective colors are transferred in a superimposed fashion reaches the position facing a secondary transfer roller 19. In this position, the secondary transfer tilt roller 12 sandwiches the intermediate transfer belt 8 together with the secondary transfer roller 19 to form a secondary transfer tongs. The four-way toner images formed on the intermediate transfer belt 8 are transferred onto a recording medium P such as a transfer sheet conveyed to the position of the secondary transfer tongs. At this time, the non-transfer toner that has not been transferred onto the recording medium P remains on the intermediate transfer belt 8.
[042] After this, the intermediate transfer belt 8 reaches the position of the intermediate transfer cleaning unit (not shown). In this position, non-transfer toner on the intermediate transfer belt 8 is collected.
[043] As a result, a series of transfer processes performed on the intermediate transfer belt 8 is finished.
[044] The recording medium P transported to the position of the secondary transfer tongs is transported through a paper feed roller 27, a pair of backing rollers 28, and the like, from a paper feed unit 26 disposed below the body of the apparatus 100.
[045] Specifically, a plurality of recording medium P such as transfer sheets are stored in superimposed form in the paper feed unit 26. If the paper feed roller 27 is rotatably driven counterclockwise in figure 1 , the top recording medium P is fed in the direction between the rollers of the pair of backing rollers 28.
[046] The recording medium P fed to the pair of backing rollers 28 stops at the position of a roller tongs of the pair of backing rollers 28 which stopped the rotational drive. In synchronization with the timing of the color image on the intermediate transfer belt 8, the pair of backing rollers 28 is rotatably driven, and the recording medium P is conveyed towards the secondary transfer tongs. Thus, an image in the desired color is transferred to the recording medium P.
[047] Thereafter, the recording medium P to which the color image was transferred in the position of the secondary transfer tongs is transported to the position of a fixing device 20. In this position, the color image transferred to the surface it is fixed to the recording medium P by heat and pressure by a clamping strap and a pressing roller.
[048] After this, the recording medium P passes through between the rollers of a pair of eject rollers 29 and then is ejected out of the apparatus. A recording medium P ejected out of the apparatus by the pair of ejector rollers 29 is sequentially stacked in a stacking unit 30 as an output image.
[049] Thus, in the imaging apparatus, a series of imaging processes is finished.
[050] In the following, a configuration and operation of the developing device in the imaging unit will be described in more detail with reference to figure 2.
[051] The 5Y developer device includes a 51Y developer roller facing the 1Y photosensitive drum, a 52Y doctor blade facing the 51Y developer roller, two shipping screws disposed in the 53Y and 54Y developer storage units, a 56Y density detection sensor for detecting the density of toner contained in the developer, and the like. The developing roller 51Y is configured with a magnet fixedly disposed therein, a sleeve rotating around the magnet, and the like. A two-component G developer composed of a carrier and a toner is stored in developer storage units 53Y and 54Y. The developer storage unit 54Y is communicated with a toner falling onto the transport path 64Y through an opening formed above it.
[052] The 5Y developing device having the configuration described above operates as follows.
[053] The sleeve of the development roller 51Y rotates in the direction of an arrow in figure 2. The developer G supported on the development roller 51Y by a magnetic field formed by the magnet moves on the development roller 51Y as the cute glove.
[054] The developer G within the developer device 5Y is adjusted so that a ratio of the toner (toner density) contained in the developer can be within a predetermined range. Specifically, as the toner inside the 5Y developer device is consumed, the toner stored in the 32Y toner container is fed into the 54Y developer storage unit through the 60Y toner feed device (for example, see figure 3) . A configuration and operation of the toner feeding device will be described in detail later.
[055] Thereafter, the toner fed into the 54Y developer storage unit circulates through the two developer storage units 53Y and 54Y while being mixed and stirred together with the G developer by the two 55Y transport screws (movement in one vertical direction to a plane of the paper in figure 2). The toner in developer G is absorbed into the carrier by frictional electrification with the carrier and supported on the development roller 51Y along with the carrier by the magnetic force formed on the development roller 51Y.
[056] The developer G supported on the developer roller 51Y is transported in a direction of an arrow in figure 2 and then reaches the position of the doctor blade 52Y. The developer G on the development roller 51Y is set to an appropriate amount of developer in this position and then transported to the position (a development area) facing the photosensitive drum 1Y. Toner is absorbed into a latent image formed on the 1Y photosensitive drum by a magnetic field formed in the developing area. Thereafter, as the sleeve rotates, the developer G remaining on the developer roller 51Y reaches above the developer storage unit 53Y and leaves the developer roller 51Y in this position.
[057] In the following, the 60Y, 60M, 60C and 60K toner feeding devices will be described in detail with reference to figures 3 to 5.
[058] Referring now to figure 3, the toners inside the 32Y, 32M, 32C and 32K toner containers installed in the toner container storage unit 70 of the apparatus body 100 are properly fed into the developing devices by the devices Toner feed slots 60Y, 60M, 60C and 60K respectively installed for toner colors as the toners inside the respective color developing devices are consumed.
[059] The four 60Y, 60M, 60C and 60K toner feeding devices and the 32Y, 32M, 32C and 32K toner containers (the developer containers) have almost the same configuration except that the toner colors used in the process of image formation are different. Thus, a description will be made focusing on the 60Y toner feeding devices and the 32Y toner container corresponding to yellow, and a description of the 60M, 60C and 60K toner feeding devices and the 32M, 32C and 32K toner containers corresponding to the three remaining colors will be appropriately omitted.
[060] With reference to figure 1, if a body cover (not shown) installed on the front side of the apparatus body 100 (the front side in a direction vertical to the paper plane in figure 1) is opened, the storage unit of toner container 70 (an insertion opening 71) is exposed. In the state that a longitudinal direction of the 32Y, 32M, 32C and 32K toner containers (the developer containers) is a horizontal direction, an operation of attaching/detaching the 32Y, 32M, 32C and 32K toner containers to/ from the front of the apparatus body 100 (a clamping/peeling operation in which the longitudinal direction of the toner container is a clamping/peeling direction).
[061] As illustrated in figure 4, when the 32Y, 32M, 32C and 32K toner containers are mounted on the toner container storage unit 70 of the apparatus body 100 (movement in a direction of an arrow Q), at together with the assembly operation, a shutter member 34d of the 32Y, 32M, 32C and 32K toner containers moves, and thus a toner discharge opening W (a discharge opening) is opened, so that the openings Toner supply ports 73w (for example, see figure 3) of the 60Y, 60M, 60C and 60K toner supply devices are communicated with the toner discharge opening W. Toner stored in the 32Y, 32M, 32C and toner containers 32K is discharged from the W toner discharge opening and stored in a 61Y toner tank unit through the 73w toner feed opening of the 60Y, 60M, 60C and 60K toner feed devices.
[062] Referring to the schematic view of Figure 3, the 32Y toner container includes a cap section 34Y which is a nearly cylindrical shaped toner bottle and is commonly held non-rotatably in the toner container storage unit 70 and a container body 33Y (a bottle body) in which a gear 33c is integrally formed. The container body 33Y is relatively rotatably retained in the cap section 34Y and is rotatably driven in a direction of an arrow in Figure 3 by a drive unit, a drive gear 81 and the like. As the container body 33Y rotates, the toner stored inside the toner container 32Y (the container body 33Y) is transported in a longitudinal direction (conveying from left to right in Figure 3) by a protrusion 33b formed in an inner peripheral surface of the container body 33Y in a helical shape, and toner is discharged from the toner discharge opening W of the cap section 34Y. That is, to the extent that the container body 33Y of the toner container 32Y is properly rotatably driven by the drive unit 91, the toner is properly supplied to the toner tank unit 61Y. Also, when each of the 32Y, 32M, 32C and 32K toner containers reaches the end of its life (when the stored toner is nearly consumed and becomes empty), it is replaced with a new one.
[063] Referring to figure 3, 60Y, 60M, 60C and 60K toner feeding devices include 70 toner container storage unit, 61Y toner tank unit, 62Y toner transport screw, a 65Y agitation member, a 66Y toner end sensor, the drive unit 91, and the like.
[064] Toner tank unit 61Y is arranged below toner discharge opening W of toner container 32Y and stores the discharged toner from toner discharge opening W of toner container 32Y. The bottom of the 61Y toner tank unit is connected with an upstream section of the 62Y toner transport screw.
[065] The 66Y Toner End Sensor which detects that the toner stored in the 61Y Toner Tank Unit becomes less than a predetermined amount is installed on the wall surface of the 61Y Toner Tank Unit (in the position of a predetermined height from the bottom). A piezoelectric sensor or similar can be used as the 66Y toner end sensor. When the control unit 90 detects that the toner stored in the toner tank unit 61Y becomes less than a predetermined amount (toner end detection) via the 66Y toner end sensor, the drive unit 91 rotates the container body 33Y of the toner container 32Y for a predetermined time under the control of the control unit 90, so that toner is fed to the toner tank unit 61Y. Furthermore, when the toner end detection by the 66Y toner end sensor is not released even if this control is repeated, it is recognized that there is no toner in the 32Y toner container, and a message to encourage container replacement 32Y toner cartridge is displayed on a monitor unit (not shown) of the machine body 100.
[066] In addition, the 65Y agitation member which prevents toner stored in the 61Y toner tank unit from being installed in the center section of the 61Y toner tank unit (near the 66Y toner end sensor). The 65Y agitation member has a flexible member installed on a shaft section and rotates clockwise in figure 3 to agitate the toner inside the 61Y toner tank unit. In addition, the leading end of the flexible member of the 65Y stirring member comes into sliding contact with the sensing surface of the 66Y toner end sensor in a period of rotation, thereby preventing a problem where toner is fixed to the surface of 66Y toner end sensor detection and thus a degree of detection accuracy decreases.
[067] Although not shown, the 62Y toner transport screw transports the toner stored in the 61Y toner tank unit obliquely upwards. Specifically, the 62Y toner transport screw linearly transports toner from the bottom of the 61Y toner tank unit (the lowest point) toward the top of the 5Y developer device. The toner transported by the 62Y toner transport screw falls through the toner falling onto the 64Y transport path (for example, see figure 2) by its own weight and is fed into the 5Y developer device (the developer storage unit 54Y).
[068] Referring to Fig. 4, the toner container storage unit 70 mainly includes a lid receiving section 73 for holding the lid section 34Y of the toner container 32Y, a bottle receiving section 72 (a bearing of container body) for retaining the container body 33Y of the toner container 32Y, and an insertion opening 71 which functions as an insertion opening at the time of assembling operation of the toner container 32Y.
[069] In the following, the toner container storage unit 70 (the bottle receiving section 72 and a cap receiving section 73) will be described in detail with reference to figures 6 to 17.
[070] Firstly, as described above with reference to figures 4 and 5, the vial receiving section 72, the cap receiving section 73 and the insertion opening 71 (which is not shown in figure 5) are formed in the unit container storage unit 70. The toner container 32Y is mounted to the toner container storage unit 70 through the insertion opening 71 by a user squeezing a clamping section 33d in a state in which the longitudinal direction is the direction. horizontal and the horizontal direction is the mounting direction where the cap section 34Y is the head of the container body 33Y. The 32Y toner container inserted through the insertion opening 71 is pushed towards the cap receiving section 73 by the user while sliding on a vial receiving surface 72a of the vial receiving section 72 (for example, see Figures 5, 6 and 9). Referring to Figure 6, in vial receiving section 72, vial receiving surface 72a is formed for each color, and toner containers 32Y, 32M, 32C and 32K corresponding to respective colors are inserted (inserted in one direction of a supposed white). Furthermore, referring to Figure 8, even in the cap receiving section 73, the bottle receiving sections 73Y, 73M, 73C and 73K are formed for the respective colors, and the toner containers 32Y, 32M, 32C and 32K corresponding to the respective colors are inserted (inserted in a direction of supposed white). In this position, the cover receiving section is non-rotatably retained. With reference to Figures 5 and 24(A), the vial receiving surface 72a, a tampon release stimulus section 72b, and the like, are formed in the vial receiving section 72 of the toner container storage unit 70 .
[071] The vial receiving surface 72a functions as a 32Y toner container sliding surface at the time of the 32Y toner container attachment/detachment operation and functions as a swivel-actuated container body retaining unit 33Y after the 32Y toner container has been completely adjusted.
[072] Referring to Figure 5, the buffer release stimulus section 72b is a trapezoidal rib formed above the vial receiving surface 72a (on the downstream side of the 32Y toner container in the mounting direction). Referring to Fig. 24, the plug release stimulus section 72b pushes a plug release section 34d21 of the plug member 34d up and releases a state of contact between a plug section 34d22 and a contact section 34n5 together. with 32Y toner container mounting operation (allows an opening operation of shutter member 34d).
[073] Referring to Figures 14A, 14B and 15, in the lid receiving section 73 of the toner container storage unit 70, a main reference pin 73a, a sub reference pin 73b, a contacted slot 73m, a slot side 73h, a wall section 73g, a through hole 73f, and the like are arranged.
[074] The main reference pin 73a and the sub reference pin 73b, as positioning pins, are fitted into a first positioning hole 34a and a second positioning hole 34b of the cover section 34Y of the 32Y toner container illustrated in the figures 20 and 21, respectively. Positioning of the cover section 34Y is carried out in the cover receiving section 73.
[075] Referring to Figure 7, the main reference pin 73a is formed to be longer than the reference sub pin 73b in the longitudinal direction (the position of the reference surface which is the base section is formed on the same flat surface ). In addition, the main reference pin 73a has a tapered main end portion. Thus, in the operation of fixing the toner container 32Y on the lid receiving section 73 in the longitudinal direction, the toner container 32Y can be smoothly mounted on the lid receiving section 73.
[076] Furthermore, with reference to figures 14A, 14B and 15, the contacted groove 73m is the inner wall of the cap receiving section 73 and is also a concave section that is formed, above the main reference pin 73a, at a groove shape on an upstream side in the mounting direction farther than the main end section of the main reference pin 73a. A guide rail section 34e which is formed to extend in the longitudinal direction on an upper outer circumference of the cover section 34Y of the toner container 32Y which will be described later is fitted into the contacted groove 73m before the main reference pin 73a is inserted in the positioning hole 34a.
[077] With reference to Figures 12 and 15, the side groove 73h which is formed to extend in the longitudinal direction and is penetrated towards the outer circumferential side of the cap receiving section 73 is formed on each of both sides of the inner wall of the lid receiving section 73 in a symmetrical relationship from left to right. Furthermore, with reference to Figures 12 and 13, lid section interleaving members 73r which have an almost pentagonal shape when viewed from the top and a groove section 73r1 (which is formed to be connected with a side groove 73h ) when viewed in the longitudinal direction are disposed on an outer circumferential side of the cap receiving section 73 in a symmetrical relationship from left to right.
[078] The lid intercalating member 73r is formed from a different member from the lid receiving section 73, fitted within a tooth formed on the outer circumferential surface of the lid receiving section 73, stimulated by a coil spring of torsion 93 arranged above it centering on a cylindrical shaft, and thus compressed against the side of the lateral groove 73h. As a result, the side slot 73h is connected with the slot section 73r1 of the lid section insert member 73r, and a pair of deeper left and right slot sections is apparently formed.
[079] In the case of attaching or detaching the 32Y toner container, the side ledge 34c formed on the cap section 34Y pushes and passes through the cap section intercalating member 73r stimulated by the torsion spiral spring 93 within the section deeper grooves described above (one in which groove section 73r1 is integrally formed with side groove 73h). Thus, the user who performs the operation of attaching/detaching the 32Y toner container to/from the body of the imaging apparatus 100 (the lid receiving section 73) can feel a click sensation synchronized with the operation of fixation/detachment and perform the fixation/detachment operation of the 32Y toner container at an optimal speed (acceleration) except for an indifferent speed.
[080] With reference to figures 14A and 15, on the inner side wall surface of the lid receiving section 73 (the wall surface arising in a vertical direction on an inner side of the apparatus towards the apparatus), the hole through 73f having a shape obtained by connecting and overlapping the edge lines of an elliptical hole and a square hole extending in the vertical direction is formed. A connector 73e (eg see figure 16) which will be described later is installed to be exposed on the inner wall side of the cap receiving section 73 through the hole through 73f (eg see figure 17). When the toner container 32Y is mounted on the cap receiving section 73 (the apparatus body 100), the connector 73e comes into face contact with an ID chip 35 disposed at the leading end of the cap section 34Y and thus , the communication of information can be effected between the ID chip 35 and the apparatus body 100 (the control unit 90).
[081] One way of installing the connector 73e onto the cap receiving section 73 of the toner container storage unit 70 will be described below.
[082] The four connectors 73e are arranged on the cap receiving sections 73, corresponding to the 32Y, 32M, 32C w 32K toner containers of the respective colors of yellow, magenta, cyan and black. Referring to Figure 8, the four connectors 73e are arranged in-line on a single rectangular common electronic substrate 95. Specifically, fitting a spring fit 73e4 formed in the bottom of the connector 73e into a hole (not shown) formed in the common electronic substrate 95, connector 73e is attached to common electronic substrate 95.
[083] Furthermore, with reference to Figures 8 and 17, the common electronic substrate 95 to which the four connectors 73e are attached is installed and attached along the direction of the arrangement of four cover receiving sections 73K, 73C, 73M and 73Y in the state that the four connectors 73e are inserted into the cap receiving section 73 through the holes through 73f, respectively. Specifically, four screws 99 are screwed into 73x female screw sections formed below the outer wall sections of the four cover receiving sections 73K, 73C, 73M and 73Y through holes formed in common electronic substrate 95, and common electronic substrate 95 it is screw-coupled with the cover receiving section 73 from the outside.
[084] A configuration and operation of the 73e connector will be described below.
[085] Referring to Figure 16, connector 73e includes a connector body 73e1, four side terminals of body 73e2, two positioning pins 73e3 (protruding positioning sections), and the like. The four side terminals of body 73e2 of connector 73e are flat metal members (or linear, respectively, have one terminal side as a fixed terminal and the other terminal side as a free end, and are fixed to the body of connector 73e1. The 73e2 body sides have curved sections (sections that become contact points with a metallic buffer 35a like a metallic plate) that curve towards the ID chip side 35 on the end side thereof. of cap 34Y in cap receiving section 73, the curved section of the side terminal of body 73e2 is shifted in a -X direction of figure 16 and slides in the left direction of figure 29 (next to a first virtual line S1) a starting from a center section in the longitudinal direction while gradually increasing the contact pressure on the metallic damper 35a (the metallic plate) of the ID chip 35 disposed in the cap section 34Y.
[086] As illustrated in figure 16, the leading end section of the positioning pin 73e3 has a conical shape so that engagement with a notch 35b1 of the ID harness 35 can be effected smoothly.
[087] With reference to figures 14A, 14B, 15 and 17, a wall section 73g is installed to surround the lower section and the side section of the hole through 73f in which the connector 73e is installed. When forming the 73g wall section, even if the toner is spread from the proximity of the toner discharge opening W of the 32Y toner container to the outside, as long as the scattered toner is blocked by the 73g wall section, the scattered toner it is difficult to directly adhere to the 73e connector and the ID chip 35. Thus, a contact failure (a communication failure) between the 73e connector (the 73e2 body side terminal) and the ID chip 35 (the 35a metal damper) ) caused by scattered toner can be suppressed.
[088] The necessary information is exchanged between the ID chip 35 (the information storage device) of the 32Y, 32M, 32C and 32K toner containers and the connector 73e of the body of the apparatus 100. The information is communicated between both sides includes information such as a manufacturing number, a manufacturing date and the number of recycling times of the toner container or ID chip, information such as capacity, a batch number, and the color of a toner, and the information such as a usage history of the imaging apparatus body 100. On the ID chip 35 (the information storage device), the electronic information is stored in advance before being installed in the imaging apparatus body 100 (or the signature received from the body of the apparatus 100 after it is installed is stored). The ID chip 35 (the information storage device) will be described in more detail later.
[089] In the following, the 21Y, 32M, 32C and 32K toner containers will be described in detail with reference to figures 18 to 30.
[090] Referring to figures 18 to 20, the toner container 32Y mainly includes the container body 33Y (a bottle body) and the cap section 34Y (a bottle cap) disposed on the head thereof. In addition, the ID chip 35 as the information storage device or the like is detachably installed in the lid section 34Y of the toner container 32Y.
[091] At the head of the container body 33Y, the gear 33c which rotates integrally together with the container body 33Y and an opening A are arranged on an end side in the longitudinal direction (the left to right direction in figure 30) (for example, see figures 19 and 30). The opening A is disposed in the head of the container body 33Y (the position that becomes the front side in the assembly operation) and discharges the toner stored in the container body 33Y towards the inner space of the lid section 34Y (a hollow space , for example, see figure 30).
[092] In addition, as toner is consumed on the side of the body of the imaging apparatus, transporting the toner from the interior of the container body 33Y to the hollow space inside the cap section 34Y (rotary drive of the container body 33Y) is performed properly.
[093] The gear 33c interlocks with a drive gear 81 disposed in the toner container storage unit 70 of the apparatus body 100 and rotatably drives the container body 33Y centering on a rotational axis. Specifically, gear 33c is exposed through notch hole 34x (eg see Figure 18) formed in the outer circumferential surface of cap section 34Y which will be described later and interlocks with drive gear 81 of apparatus body 100 in position of weaving downward obliquely in Figure 21. Furthermore, the driving force is transferred from the driving gear 81 to the gear 33c, and the container body 33Y rotates clockwise in Figures 3 and 21. In the present first embodiment , drive gear 81 and gear 33c are cylindrical gears.
[094] With reference to figure 18, on the other end side of the container body 33Y in the longitudinal direction (the rear end section in the mounting direction), the clamping section 33d is tightened by the user when carrying out the clamping/detaching work of the 32Y toner container is arranged. The user mounts the 32Y toner container on the body of the imaging apparatus 100 while squeezing the clamping section 33d (moving the 32Y toner container in an arrow direction in figure 18).
[095] Furthermore, on the outer circumferential surface of the container body 33Y, the helical protrusion 33b (a helical groove when viewed from the side of the outer circumferential surface) is disposed. The helical protrusion 33b rotatably drives the container body 33Y in a predetermined direction and discharges toner through the opening A. The container body 33Y having the configuration described above can be manufactured by blow molding together with gear 33c disposed on the circumferential surface of the same and the clamping section 33d.
[096] Referring to Figure 30, in the toner container 32Y according to the present first embodiment, a stirring member 33f which rotates together with the container body 33Y is fitted within a section of the bottle mouth 33a (the opening A) illustrated in Figure 19. The stirring member 33f is a rod-like member that extends from the hollow space within the cap section 34T into the container body 33Y. Since the stirring member 33f rotates together with the opening A of the container body 33Y, the toner discharge efficiency from the opening A is improved.
[097] With reference to figures 19 and 30, an engaged section 33j (a flange section), which is engaged with a grip section 34j (eg see figure 21) of the cap section 34Y to connect both members 33Y and 34Y with each other is formed around the opening A of the container body 33Y to make a circle around the outer circumference. As described above, container body 33Y is pivotally fitted within cap section 34Y.
[098] Furthermore, with reference to figures 19 and 30, a head section 33Yc of the container body 33Y (almost the position in which the gear 33x is formed) is formed to have the inner diameter smaller than the inner diameter of a storage section 33Ya storing the toner (the position at which the helical ridge 33b is formed). In the container body 33Y, a pumping section 33Yb (a section circled by an alternating long and short dotted line in figure 20) formed to protrude from the inner circumferential surface of the same towards the inside is disposed between the head section 33Yc and the 33Ya storage section. As the container body 33Y rotates, toner transported in the direction of opening A by the helical boss 33b is pumped to the small diameter section of the head section 33Yc by the pumping section 33Yb. Thereafter, the pumped toner to the small diameter of the head section 33Yc is discarded towards the hollow space of the cap section 34Y from the opening A while being agitated by the agitating member 33f.
[099] Referring to Figures 20 to 23, the ID chip 35 (the information storage device), the shutter member 34d, a shutter seal 36, and the like are installed in the lid section 34Y of the toner container. 32Y.
[0100] With reference to figure 22, the cap section 34Y has a structure in which a roughly cylindrical section (a cylindrical section of larger diameter 34Y1, a cylindrical section of medium diameter 34Y2, and a cylindrical surface of small diameter 34Y3) at that the outer diameter and inner diameter decrease from the side of the container body 33Y towards the side of the plug member 34d in three stages is combined with a box section (a wide width box section 34Y11 and a box section narrow-width box 34Y12) arranged at the bottom, in which the width in the horizontal direction decreases in two stages are combined.
[0101] A 34z insert section (eg see figure 30) including the large diameter cylindrical section 34Y1, the medium diameter cylindrical section 34Y2, the wide width box section 34Y11, and part of the wide box section Narrow 34Y12 is formed on the 34Y cap section. The head section 33Yc of the container body 33Y and part of the pumping section 33Yb are inserted into the insertion section 34z. Referring to Figure 30, in the insert section 34z, the cylindrical section of average diameter 34Y2 is formed to have the inside diameter D smaller than the tip diameter of the gear 33c and larger than the outside diameter of the opening A of the body of the 33Y container. In addition, the small diameter cylindrical section 34Y3 is formed to have the inside diameter B smaller than the inside diameter D of the medium diameter cylindrical section 34Y2 and smaller than the outside diameter of the opening A.
[0102] An annular cap seal 37 (an elastic seal) in which the diameter of the opening becomes nearly the same as the inner diameter B is attached to an annular vertical wall surface (the surface facing the circumference of the opening A of container body 33Y), which connects the medium diameter cylindrical section 34Y2 with the small diameter cylindrical section 34Y3 by a double-sided tape. The head section 33Yc and part of the pumping section 33Yb are inserted into the insertion section 34z so that an edge of the opening A of the head section 33Yc of the container body 33Y contacts and cuts into the cap seal 37. By the configuration described above, a functional section such as part of gear 33c (a section excluding a section exposed from the slot hole 34x) and a connecting section between the cap section 34Y and the container body 33Y are covered with the cylindrical section of larger diameter 34Y1. For this reason, even when the toner container 32 is only held by the user, the user can be prevented from touching the functional portion, and even if an unexpected external force (for example, an unexpected knock) is applied to the toner container 32Y , toner leakage from the connection section or damage to the 33c gear's touch surface can be alleviated. Furthermore, since the annular lid seal 37 is excellent in slip property and surface elasticity, even if the container body 33Y rotates while piercing inside the annular lid seal 37, toner leakage caused by a gap generated between container body 33Y and cap section 34Y. As a sealing material for the cap 37, a high-density microcell urethane sheet having a structure that is high in density, thin, and uniformly different from generally soft polyurethane (PUR) foam is used. As a result, compared to the case of using general PUR, the sealing establishment of the lid 37 is small, and the sealing property between the container body 33Y and the lid section 34Y can be maintained for a long time.
[0103] With reference to figures 23 and 30, within the narrow width box section 34Y12 positioned below the small diameter cylindrical section 34Y3 of the cap section 34Y, arranged in a toner drop path C having a hole of a Hexagonal cylindrical shape for discharging the discharged toner from opening A of the container body 33Y from the outside downwards in the vertical direction (falling by its own weight). The toner drop path C has a predetermined flow passage area of a hexagonal cross section and communicates the lower lateral circumferential surface within the small diameter cylindrical section 34Y3 with the toner discharge opening W (the discharge opening). Toner discharged into small diameter cylindrical section 34Y3 of cap section 34Y from opening area A of container body 33Y falls through toner drop path C of hexagonal cylindrical shape by its own weight and then is gently discharged from the toner discharge opening W out of the container (the 61Y toner tank section).
[0104] At the bottom of the narrow-width box section 34Y12, part of the shutter member 34d (a main shutter section 34d1) to effect the opening/closing of the toner discharge opening W together with the clamping/detaching operation from the toner container 32Y to/from the toner container storage unit 70 is retained to be slidably movable.
[0105] Figures 22 and 23 illustrate an operation in which the shutter member 34d starts opening the toner discharge opening W and then completes the opening. Figures 24(A) to 24(C) are schematic views illustrating the opening operation of the shutter member 34d (a deformation section of the shutter 34d2) at the time. Furthermore, Figures 25 and 26 are perspective views illustrating the shutter member 34d. In Figures 24(B) and 24(C), the cap section 34Y, the cap receiving section 73, and the vial receiving section 72 that are illustrated in Figure 24(A) are partially omitted.
[0106] Referring to Figures 22 to 26, the shutter member 34d is formed of a resin material such as polystyrene and mainly includes a plate-like main shutter section 34d1 and a shutter deformation section 34d2 that stresses the main shutter section 34d1 is thinner in thickness than main shutter section 34d1 and has elasticity.
[0107] With reference to figures 25 and 26, in the main shutter section 34d1 of the shutter member 34d, the vertical wall 34d13 remaining in both side end sections (vertical walls extending in parallel in the mounting direction of the toner 32Y) and a shutter slider 34d12 having a plurality of protruding objects protruding from the vertical walls 34d13 are formed in both side end sections, respectively. Shutter slider 34d12 includes a slide protruding section 34d12a protruding from the inner side surface of the vertical wall 34d13, an L-shaped protruding section 34d12b protruding from the outer side surface of the vertical wall 34d13, and a pair of prismatic sections 34d12c that are arranged to protrude from the same outer side surface as the engaged protruding section 34d12b and extend from the body of the main shutter section 34d1 to the wide-width box section 34Y13. However, in the narrow-width box section 34Y12 of the cover section 34Y, a pair of sliding grooves 34t (eg see figure 23) extending on both side walls in the longitudinal direction is formed in a rib. The protruding slide section 34d12a is fitted within the slide groove 34t, and thus the main shutter section 34d1 of the shutter member 34d is supported movable by sliding in the cap section 34Y.
[0108] In addition, a plug seal 36 adheres to the upper surface of the main plug section 34d1 (the surface facing the toner discharge opening W) as a sealing member. Plug seal 36 is a thin rectangular parallelepiped-like elastic seal, and similarly to cap seal 37, a high density microcell urethane sheet is used as a material in view of the slip property and surface elasticity. For this reason, even if the opening/closing operation of the shutter member 34d is repeated, a sealing feature at the toner discharge opening W can be maintained in the state where the shutter member 34d closes the toner discharge opening. W.
[0109] The protruding sliding section 34d12a of the shutter slider 34d12 is fitted within the sliding groove 34t of the narrow-width box section 34Y12 (the cover section 34Y). Furthermore, in this state, the closure seal 36 is sandwiched between a protrusion 34r (for example, see Fig. 23) of a hexagonal ring shape protruding downwardly along an edge of the hexagonal toner discharge opening W of the narrow-width box section 34Y12 and a main plug section 34d1, and plug seal 36 becomes a lightly compressed state. In this state, shutter member 34d moves along slide slot 34t, and thus main shutter section 34d1 opens or closes toner discharge opening W while suppressing toner leakage. Furthermore, in the state where the main shutter section 34d1 (the shutter member 34d) has closed the toner discharge opening W, the toner leakage between the main shutter section 34d1 and the toner discharge opening W is forewarned.
[0110] Specifically, the shutter member 34d moves relatively in the longitudinal direction from the side of the cap section 34Y to the side of the container body 33Y (moves to the left in figure 30) to open the opening of toner discharge W and moves relatively in the longitudinal direction from the container body side 33Y to the cap section side 34Y (moves to the right in figure 30) to close the toner discharge opening W. The shutter member 34d opening/closing operation (the W toner discharge opening opening/closing operation) is performed in conjunction with the 32Y toner container fixing/detaching operation to/from the storage unit of toner container 70 (the body of the machine 100) in the longitudinal direction.
[0111] With reference to figures 25 and 26, the plug deformation section 34d2 of the plug member 34d is formed integrally with the main plug section 34d1 and formed at the edge thickness thinner than the edge thickness of the section. main shutter 34d1 as described above. Shutter deformation section 34d2 primarily includes two thin flat plate sections 34d23 extending from the end surface of the main shutter section 34d1 into container body 33Y and a plate-like member 34d24 extending in one direction orthogonal to the longitudinal direction to connect the two 34d23 flat plate sections together near the leading end sections (the free ends). The shutter deformation section 34d2 is formed to be elastically deformed in the vertical direction from a fixed end (a connecting portion) with the main shutter section 34d1 as a reference point. At the main end sections (the free ends) of the two flat plate sections 34d23, plug sections 34d22 are formed to secure the shutter member 34d so as to prevent careful opening of the toner discharge opening W as will be described later. On the bottom side of the plate-like member 34d24, the plug release section 34d21 is formed which is a slanted protrusion (having a triangular cross section) protruding, in a mountain shape, downwards in the vertical direction and releasing securing the plug member 34d in cooperation with the plug release stimulus section 72b of the plug receiving section 73 as will be described later.
[0112] With reference to figures 22 and 23, in the wide-width box section 34Y11 positioned below the cylindrical section of larger diameter 34Y1 of the cap section 34Y, a shutter storage section 34n is formed which stores the deformation section of the 34d2 shutter inside it at the time of shutter opening. Between the four side surfaces of the wide-width box section 34Y11, the two side surfaces facing the longitudinal direction (one direction of an arrow in figure 22) are opened. Particularly, on the side surface formed on the side of the toner discharge opening W, part of the wall surface is formed on both side ends of the bottom side, but most of it functions as an opening 34n1 extending in the horizontal direction . The opening 34n1 is formed so that the two surfaces including the side surface and the bottom surface which are on the toner discharge opening W side of the wide-width box section 34Y11 are cut away. Between the edge sections of opening 34n1, an edge section formed to lie from the bottom surface of the wide-width box section 34Y11 in the vertical direction contacts the contact section 34n5.
[0113] The plug section 34d22 of the shutter deformation section 34d2 is a wall section formed at an end section farthest from the shutter deformation section 34d2 (the leading end of the shutter deformation section 34d2 away from the shutter section. main shutter 34d1) in the opening direction (the left direction in figure 24). The plug section 34d22 of the shutter deformation section 34d2 contacts the contact section 34n5 and thus restricts the shutter member 34d from moving in the direction of the opening of the toner discharge opening W from the state in which the toner discharge opening W is closed. That is, when the 32Y toner container is in a separate state (the state in which it is not attached to the apparatus body 100 yet), since the plug section 34d22 of the shutter member 34d contacts the section of 34n5 contact, a phenomenon where the shutter member 34d moves towards the opening on its own and thus opens the toner discharge opening W does not happen.
[0114] However, the buffer release section 34d21 contacts the buffer release stimulus section 72b (for example, see figures 5 and 24) formed in the vial receiving section 72 in conjunction with the assembly operation from the toner container 32Y to the toner container storage unit 70 and is pushed up by the buffer release stimulus section 72b (as external force is applied upwards). Then, plug deformation section 34d2 is elastically deformed upwards, and plug section 34d22 is also displaced upwards. As a result, the context state between the plug section 34d22 and the contact section 34n5 is released, so that the shutter member 34d can move in the opening direction.
[0115] An operation of the shutter member 34d in conjunction with the operation of assembling the toner container 32Y to the toner container storage unit 70 will be described in detail below with reference to figures 24(A) to 24(C), The position of the closure member 34d in Figures 24(A) and 24(C) corresponds to the position of the closure member 34d in Figures 22 and 23, respectively.
[0116] As illustrated in figure 24, the operation of assembling the toner container 32Y to the toner container storage unit 70 (movement in the left direction in figure 24) starts, and when the plug release section 34d21 of the shutter 34d does not reach the position of plug release stimulus section 72b (eg see also figure 5) formed in vial receiving section 72, plug section 34d22 of plug member 34d contacts section of contact 34n5, and thus the movement of the shutter member 34d in the operating direction is restricted. Furthermore, on the upper surface of the vial receiving section 72 on the side of the cap receiving section 73 near the tampon release stimulus section 72b, a bristle brush 72f is arranged to scrub the bottom surface of the closure member. 34d and clean the contamination. Particularly, the bristle brush 72f is effective in clearing flying toner adhering to the bottom surface of the shutter member 34d during an attachment/detachment operation of the toner container 32Y.
[0117] After that, when the 32Y toner container assembly operation proceeds, as illustrated in figure 24(B), the tampon release section 32d21 is pushed up by the tampon release stimulus section 72b, and so on shutter deformation section 34d2 is elastically deformed from the connection position (a section circled by an alternating long and short dotted line) as the reference point. As a result, the contact state between the plug section 34d22 and the contact section 34n5 is released, and thus the shutter member 34d can move relatively in the opening direction.
[0118] Thereafter, the shutter member 34d comes into contact with the wall section (a section indicated as "contact position" in the drawings) formed around the toner feed opening 73W of the plug receiving section 73, and thus movement in the toner container storage unit 70 (the lid receiving section 73) is restricted (the shutter member 34d does not move at all in the longitudinal direction). However, since movement in the mounting direction of the toner container 32Y is effected, the shutter member 34d moves with respect to the discharge opening W in the direction of the opening. That is, as illustrated in Figure 24(C), the shutter member 34d moves relatively to the side of the container body 33Y, and thus the shutter deformation section 34d2 is stored in the shutter storage section 34n . As a result, the opening of the toner discharge opening W is completely finished by the movement of the shutter member 34d in the direction of the opening. In addition, the toner discharge opening W combines with the toner feed opening 73w of the cap receiving section 73 in a superimposed shape, and a main toner feed passage from the toner container 32Y to the toner device. toner feed is formed. At this time, the plug release section 34d21 of the plug member 34d is stored in a notch 34n6 (for example, see figures 22 and 23) which is an opening extension section 34n1 of the plug receiving section 34n. Thus, it is possible to prevent a problem where the plug deformation section 34d2 stored in the plug storage section 34n is retained in a largely elastically deformed state by the contact between the plug release section 34d21 and the plug storage section 34n .
[0119] As described above, in the 32Y toner container according to the present first embodiment, the plug deformation section 34d2 which is elastically deformed from the connection position with the main shutter section 34d1 as the reference point is disposed on the plug member 34d, and the plug section 34d22 which restricts the movement of the plug member 34d in the opening direction and the plug release section 34d21 which releases the plug section 34d22 are arranged at the plug deformation section 34d2 . Thus, the shutter member 34d does not open the toner discharge opening W because it pleases in the state where the toner container 32Y is removed, and only when the toner container 32Y is fixed to the body of the imaging apparatus 100 , the shutter member 34d opens the toner discharge opening W in conjunction with the assembling operation thereof.
[0120] An operation of the protruding section engaged in the L-shape 34d12b referring to the shutter open/close operation will be described below.
[0121] As illustrated in Figure 25, the L-shaped engaged protruding sections 34d12b are formed on both side end sections of the main shutter section 34d1, respectively. However, although not shown because it is illustrated in the drawings of JP Patent Application No. 2011-9792, on the bottom surface within the cap receiving section 73, a pair of stimulus members is installed to face a pair of hooked protruding sections 34d12b. The pair of stimulus members is an L-shaped lever (a spindle that becomes a center of rotation is formed next to a curved L-shaped portion) that forms a symmetrical shape to each other, and an arm section in one side of them is stimulated by a torsion spiral spring. If the toner container 32Y (the cap section 34Y) is mounted on the cap receiving section 73, an arm section on the other end of the stimulus member is engaged with the engaged protruding section 34d12b and applies a stimulus force. in a direction resisting the direction in which the shutter member 34d is open. The user pushes the 32Y toner container by force overcoming the stimulus force by the stimulus member described above, and the opening of the shutter member 34d is quickly effected. As a result, a state where the toner discharge opening W does not match the toner feed opening 73w of the cap receiving section 73 only occurs instantly, and toner leakage from between the toner discharge opening W and the 73w toner feed opening can be suppressed.
[0122] On the other hand, when the 32Y toner container (the 34Y cap section) is removed from the cap receiving section 73, the stimulus member arm section becomes a stimulated state to push the protruding section engaged 34d12b in the mounting direction. The user tries to pull out the toner container 32Y by force overcoming the stimulus force by the stimulus member, and thus the closing of the shutter member 34d is quickly effected. As a result, similarly to the time of opening operation, toner leakage from between toner discharge opening W and feed opening 73w can be suppressed.
[0123] With reference to figures 20, 21 and 30, in the upper section (the roof portion) of the cap section 34T, the first positioning hole 34a extending in the longitudinal direction from the end surface of the cap section 34Y orthogonal to the longitudinal direction is formed. The first positioning hole 34a becomes a main positioning reference of the cap section 34Y in the body of the imaging apparatus 100. Specifically, the reference pin 73a (for example, see Figures 14A, 14B and 17) as the Lid receiving section positioning pin 73 is fitted into the first positioning hole 34a of lid section 34Y in conjunction with the operation of assembling the toner container 32Y to the toner container storage unit 70 in the longitudinal direction.
[0124] In the lower section (the bottom portion) of the cap section 34Y, the second positioning hole 34b extending in the longitudinal direction from the end surface of the cap section 34Y orthogonal to the longitudinal direction is formed not to reach the position of the toner discharge opening W. The second positioning hole 34b becomes a positioning sub-reference of the cap section 34Y in the body of the imaging apparatus 100. Specifically, the reference sub-pin 73b (e.g. , see Figures 14A, 14B and 17) as the positioning pin of the cap receiving section 73 is fitted into the second positioning hole 34b of the cap section 34Y in conjunction with the operation of assembling the toner container 32Y to the toner unit. 70 toner container storage in the longitudinal direction. Furthermore, the second positioning hole 34b as illustrated in Figure 21 is an oblong hole where a vertical direction is a longitudinal direction (this "longitudinal direction" has a different meaning than the "longitudinal direction" of the 32Y toner container described in the others sections).
[0125] The positioning of the cap section 34Y on the toner container storage unit 70 is effected by the two positioning holes 34a and 34b having the configuration described above.
[0126] Referring to Figure 30, the hole depth of the first positioning hole 34a is set to be greater than the hole depth of the second positioning hole 34b. The length of the main reference pin 73a in the longitudinal direction is fixed to be greater than the length of the sub reference pin 73b in the longitudinal direction. In the operation of assembling the toner container 32Y to the toner container storage unit 70 (the lid receiving section 73) in the longitudinal direction, the main reference pin 73a starts to be fitted into the first positioning hole 34a which is the main positioning reference, and then the reference sub-pin 73b starts to be fitted into the second positioning hole 34b which is the positioning sub-reference, so that the toner container 32Y can be smoothly mounted in the storage unit. toner container 70 (the cover receiving section 73). Furthermore, since the first positioning hole 34a which is long in the longitudinal direction is arranged in the ceiling section of the cap section 34Y (a section which is not buried in the toner), there is no influence on a transport property (a flow property) of the toner inside the cap section 34Y. The second positioning hole 34b which is short in the longitudinal direction is formed in the bottom of the cap section 34Y, but sufficiently performs a function as the positioning sub-reference since it can be arranged using a small space from the end surface. from cap section 34Y to toner discharge opening position W.
[0127] With reference to Figure 20, on the outer circumferential surface of the cap section 34Y above the first positioning hole 34a of the cap section 34Y, a guide rail section 34e extending in an axial direction of the first positioning hole 34a is formed. The guide rail section 34e protrudes upwards in the vertical direction from the outer circumferential surface of the cap section 34Y to be symmetrical in line with a virtual vertical line passing through the center of the hole of the first positioning hole 34a when viewed at a cross section orthogonal to the longitudinal direction (a cross section parallel to a front view of figure 21) and extends in the longitudinal direction (a vertical direction for a paper plane of figure 21). Before the main reference pin 73a is inserted into the positioning hole 34a, the guide rail section 34e is fitted into the contacted groove 73m (a concave section), which is formed in a groove shape in the inner wall of the receiving section. of cap 73 above the main reference pin 73a, from the upstream side in the mounting direction farther than the main end section of the main reference pin 73a and restricts a posture of the cap section 34Y in the horizontal direction orthogonal to longitudinal direction at the time of mounting movement to the image forming apparatus body 100 (the cap receiving section 73). Furthermore, at the leading end of the guide rail section 34e, a projecting section 34e1 protruding slightly in the longitudinal direction from the end surface of the first positioning hole 34a is formed. The protruding section 34e1 is formed into a conical shape as illustrated in Figure 20. The guide rail section 34e enters contacted grooves 73m formed in the cap receiving section 73, and thus the cap section 34Y is oriented towards the interior of the section. of cap receiving section 73. Thus, when the cap section 34Y is mounted on the cap receiving section 73, at the first positioning hole 34a, the tapered protruding section 34e1 is fitted into the contacted groove 73m before the first positioning hole 34a be fitted into the main reference pin 73a, and so the cap section 34Y is smoothly mounted on the cap receiving section 73.
[0128] With reference to Figures 20 and 21, side ridges 34c for restraining a posture of the lid section 34Y in the direction of rotation in the body of the imaging apparatus 100 (the lid receiving section 73) are formed in both the side sections of the 34Y cap section, respectively. The side ledge 34c protrudes to both sides in the horizontal direction from the outer circumferential surface of the cap section 34Y to be arranged in a virtual horizontal line passing through the center of a virtual line segment connecting the center of the hole of the first. positioning hole 14a with the center of the hole of the second positioning hole 34b when viewed in a cross section orthogonal to the longitudinal direction and extending in the longitudinal direction (a direction vertical to a paper plane of figure 21). The two side protrusions 34c are engaged with the side slot 73h and the slot section 73r1, for example, illustrated in Figure 12 while being compressed to be pushed back in a direction opposite to that pushed by the lid section insert member 73r ( for example, see figure 12) in the cap receiving section 73. Thus, the cap section 34Y is fixed to or detached from the cap receiving section 73 while the posture of the cap section 34Y in the direction of rotation is being restricted, and the putting of the cap section 34Y in the direction of rotation is restricted in the state where the cap section 34Y is mounted on the cap receiving section 73.
[0129] In more detail, on the side boss 34c, the leading end in the longitudinal direction (the mounting direction) is formed into a conical shape as illustrated in figure 20. cover receiving 73, guide rail section 34e is first fitted into contacted groove 73m, and then the two side protrusions 34c having the tapered head end are fitted into side grooves 73h and groove sections 73r1. Thus, the lid section 73 is smoothly mounted on the lid receiving section 73 in the state where the posture of the lid section 34Y is constrained with a high degree of certainty.
[0130] Referring to figures 20 and 21, at both ends of the bottom of the cap section 34Y, convex sections 34g and 34h are arranged to ensure the mismatch of the 32Y toner container (the developer container). In detail, on the upper surface side of a flat plate-like blade member extending laterally from the bottom of the cap section 34Y, the convex sections 34g and 34h are arranged to protrude upwards. The convex sections 34g and 34h are configured to be fitted within an adjustment section 72m (which is formed in the vial receiving section 72 of the toner container storage unit 70) illustrated in Figure 9 when the container assembly operation Toner Container Storage Unit 70 is correct (when the 32Y Toner Container is mounted in the true position of Toner Container Storage Unit 70).
[0131] Specifically, although not shown, the convex sections 34g and 34h are arranged in different positions depending on the color of the toner stored in the toner container (the container body). In detail, if it is assumed that the leading end in the mounting direction, when the toner container 32Y is mounted to the body of the imaging apparatus 100, is at the front, the convex sections 34g and 34h are arranged so that the positions Projections are not superimposed when viewed from the front and are arranged in different positions depending on the color. The 34g and 34h convex sections of the toner container corresponding to cyan are formed in the position to be adjusted only within the 72m cyan adjustment section of the toner container storage unit 70, the 34g and 34h convex sections of the corresponding toner container the magnets are formed in the position to be adjusted only within the 72m magenta adjustment section of the toner container storage unit 70, the 34g and 34h convex sections of the toner container corresponding to yellow are formed in the position to be adjusted only within of the yellow 72m adjustment section of the toner container storage unit 70, and the 34g and 34h convex sections of the toner container corresponding to black are formed into position to be adjusted within the black 72m adjustment section of the storage unit of toner container 70.
[0132] The configuration described above prevents a problem where the toner container of a different color (for example, the yellow toner container) is attached to the 70 toner container storage unit of a predetermined color (for example, the cyan toner container storage unit) and thus a predetermined color image cannot be formed. That is, the toner container is prevented from being mistakenly attached to the toner container storage unit.
[0133] Figure 10 illustrates the state when the operation of assembling the 32Y toner container to the 70 toner container storage unit is correct. The convex sections 34g and 34h of the cap section 34Y do not interfere with the adjustment section 72m of the vial receiving section 72. On the other hand, figure 11 illustrates the state when the operation of assembling the 32Y toner container to the toner unit 70 toner container storage is not correct. The 34g and 34h convex sections of the 34Y cap section interfere with the 72m adjustment section of the vial receiving section 72.
[0134] The ID chip 35 (the information storage device) which is characteristic in the 32Y toner container (the removable device) according to the first embodiment will be described in detail below.
[0135] Referring to figure 20, on the end surface of the cap section 34Y, the ID chip 35 as the information storage device in which various electronic information is stored is installed in the position of a retaining member 34k installed between the first positioning hole 34a and the second positioning hole 34b. The ID chip 35 is configured to be connected to connector 73e of the cap receiving section 73 in the state that the cap section 34Y is mounted on the toner container storage unit 70 (the cap receiving section 73) ( for example, see figures 3 and 17).
[0136] Specifically, in the state that the cap section 34Y is mounted on the toner container storage unit 70 (cover receiving section 73), a plurality of metallic buffers 35a (metallic plates) of the ID chip 35 enter in contact with a plurality of side terminals of body 73e2 of connector 73e. The ID chip 35 carries out communication (wire line communication) with the control unit 90 through the connector 73e as illustrated in figure 3 in the state where the cap section 34Y is retained in the cap receiving section 73.
[0137] Referring to Figures 27 to 29, in the present first embodiment, a retaining mechanism installed in the 32Y toner container (the removable device) removably installed in the body of the imaging apparatus body 100 includes a chip. ID 35 as the information storage device, the retaining member 34k as the retaining section, and the like. The ID chip 35 as the information storage device retained in the retention mechanism includes a substrate 35b, an information storage unit 35c, metallic buffers 35a as a plurality of terminals (metallic plates), and the like.
[0138] Referring to Fig. 29, the information storage unit 35c is an electronic circuit in which various information exchanged between the control unit 90 of the imaging apparatus body 100 and the toner container 32Y is stored. In Fig. 29, the information storage unit 35c is illustrated as box-like by shading lines for simplicity, but it corresponds to an assembly of a memory IC, a noise reduction capacitor, a resistor, and the like. The information storage unit 35c is disposed on the side of the rear surface of the substrate 35b (the side facing the end surface of the cap section 34Y) and electrically connected to all or some of the metallic buffers 35a as a plurality of metallic plates .
[0139] The metallic buffers 35a as the plurality of terminals contact the plurality of side terminals of the body 73e2 of the connector 73e installed in the cap receiving section 73 (the body of the apparatus 100), respectively, and exchange an electrical signal relating to the information with the body of the imaging apparatus 100 (the control unit 90). The plurality of metallic buffers 35a are disposed on the side of the front surface of the substrate 35b (the side facing the cap receiving section 73). Furthermore, the plurality of metallic dampers 35a is formed in an almost rectangular shape and ordered in a transverse direction thereof with a gap between them (a Z direction (vertical direction) in Fig. 29(A)).
[0140] On the substrate 35b on which the information storage unit 35c and the metallic buffers 35a are arranged, the positioning notches 35b1 (which is shaped like a half when an elliptical circumference is divided into two by a straight line) are formed at both ends in the vertical direction, respectively. The positioning notch 35b1 is fitted within the positioning pin 73e3 (for example, see Figures 16 and 17) as a cylindrical positioning raised section installed in the connector 73e (the body of the imaging apparatus 100) and is used for positioning the plurality of metallic snubbers 35a on the plurality of side terminals of the body 73e2.
[0141] The ID chip 35 (the information storage device) having the configuration described above is retained in the retaining member 34k (the retaining section) which is removably configured from the cap section 34Y.
[0142] The retaining member 34k (the retaining section) retains the contact-type ID chip 35 (the information storage device) to be able to move in a virtual plane (a substantially orthogonal virtual plane) to intersect with the direction of movement (a direction of an arrow in figure 17) where the metallic buffers 35a (terminals) approach and contact the side terminals of the body 73e2.
[0143] Specifically, in the present first embodiment, the retaining member 34k retains the ID chip 35 (the substrate 35b) to be able to move in a virtual plane (an XZ plane in Figure 20) orthogonal to the fixation/ detachment of the 32Y toner container to/from the body of the imaging apparatus 100. That is, the ID chip 35 (the substrate 35b) is configured to be able to move (about 1 mm) about the plane XZ in figure 20 freely to some extent in a state retained by retaining member 34k (the cap section 34Y) as illustrated in figure 20. Specifically, the ID chip 35 (the substrate 35b) is loosely retained to some extent inside the box-like retaining member 34k (the retaining mechanism). That is, the ID chip 35 is retained with a predetermined gap between the ID chip 35 and the sidewall within the retaining member 34k. With reference to figures 28 and 29, the ID chip 35 is retained so that a small clearance Δt (for example, “Δt+t” is about 0.85 to 1.05 mm) is formed in a ±Y direction in the thickness t (about 0.8 mm) of substrate 35b) inside retaining member 34k. For this reason, it is possible to make the substrate 35b remain to cross orthogonally in the insertion direction of the positioning pin 73e3 to some extent. Thus, a problem is avoided where the substrate 35b is excessively laid down in the insertion direction of the positioning pin 73e3, the positioning pin 73e3 is gripped by the notch 35b1, and thus the positioning pin 73e3 falls down to fit into the notch 35b1.
[0144] Through the configuration described above, even when the body size of the image forming apparatus 100 of the 32Y toner container decreases and so the plurality of metallic buffers 35a (terminals) on the substrate 35b are densely arranged so as to reduce the size of the ID chip 35 installed in them, a contact failure which is caused by a misplacement between the plurality of metallic buffers 35a and the side terminal of the 73e2 body of the 73e connector is difficult to occur regardless of whether or not a degree of dimension accuracy or a degree of accuracy of the assembly of an associated component is high or low.
[0145] Specifically, with reference to Figure 17, if the operation of assembling the cap section 34Y of the toner container 32Y to the cap receiving section 73 proceeds, the positioning pins 73a and 73b are inserted into positioning holes 34a and 34b, and thus cap section 34Y is positioned on cap receiving section 73. If the assembling operation of cap section 34Y still proceeds, positioning pin 73e3 of connector 73e (for example, see figures 16 and 17 ) is inserted into the notch 35b1 of the substrate 35b of the ID chip 35, and the substrate 35b (the plurality of metallic buffers 35a) is positioned with respect to the connector 73e (the plurality of side terminals of the body 73e2). In more detail, the positioning pin 73e3 contacts the edge section (or inner surface) of the notch 35b1, and thus the movement of the substrate 35b is restricted. At this time, since the ID chip 35 (the substrate 35b) having a notch 35b1 formed therein is configured to be movable about the XZ plane in the retaining member 34k, a permissible tolerance of one degree of dimensional accuracy or one degree assembly accuracy of an associated component according to mass production must be large. Thus, when the positioning between the toner container 32Y and the body of the imaging apparatus 100 is carried out, even if the position of the notch 35b1 is misaligned with the positioning pin 73e3 from the beginning, the ID chip 35 (Substrate 35b) is constrained by the tapered leading end of the positioning pin 73e3 and moved in the XZ plane, and thus the cylindrical section of the positioning pin 73e3 can be fitted into the notch 35b1. That is, regardless of the positioning between the toner container 32Y and the body of the imaging apparatus 100, the cylindrical section of the positioning pin 73e3 can be fitted within the notch 35b1. Thus, the contact failure which is caused by misplacement between the plurality of metallic snubbers 35a and the side terminals of the body 73e2 of the connector 73e is difficult to occur.
[0146] Referring to Figure 27, the retaining member 34k as the retaining section is detachably configured in the cap section 34Y and is a box-like member having an insertion opening 34k1, formed on the upper side thereof. , through which the ID chip 35 is inserted or detached.
[0147] In detail, when mounting the retaining mechanism on the cap section 34Y, the ID chip 35 (the information storage device) is first inserted into the retaining member 34k through the insertion opening 34k1 (movement in a direction of an arrow in figure 27). Thereafter, the retaining member 34k (the retaining section) having an ID chip 35 mounted thereon moves in the direction of the arrow in Fig. 27 and is snap fit within the convex section of the cap section 34Y. At this time, the retaining member 34k is secured and held in position by contacting a pedestal section 34q (arranged in position not contacting the substrate 35b) disposed in the convex section of the cap section 34Y. Furthermore, when ejecting the ID chip 35 from the cap section 34Y, an operation is performed in a procedure contrary to the procedure described above. The pedestal section 34q is a gap remaining in the mounting direction of the toner container 32Y (or in the direction of the retaining member 34k) within the concave section of the cap section 34Y and disposed in position except for a place within which the pin connector 73e3 of connector 73e must be inserted.
[0148] In the present first embodiment, the retaining member 34k is snap fit within and secured to the concave section of the cap section 34Y, but the retaining member 34k can be mounted on and screw-fixed to the concave section of the cap section 34Y. Specifically, a flaky gap having a hole in the side wall of the retaining member 34k protrudes to form a female screw section on the end surface of the cap section 34Y. The retaining member 34k is mounted on the concave section of the cap section 34Y, and in the state that the flaky gap of the retaining member 34k contacts the end surface of the cap section 34Y, a screw is screwed into the section. female screw of cap section 34Y through gap hole relative to retaining member 34k. Even in this configuration, the retaining member 34k can be comparatively easily attached to or detached from the cap section 34Y.
[0149] As described above, since the ID chip 35 (the substrate 35b) is configured to be attached to or detached from the cap section 34Y, the effectiveness of mounting the ID chip 35 (the substrate 35b) to the 32Y toner as the removable device increases, and at the same time, the effectiveness of an ID chip disassembly operation 35 (the substrate 35b) as the recycling of the 32Y toner container increases. Particularly, in the present first embodiment, the substrate 35b of the ID chip 35 is a small substrate having the size of about 12mm x 8mm to 15mm x 10mm. Whether the data output/input (data output/input when a probe terminal makes contact with the metallic buffer 35a) is close to being carried out in the state where the substrate 35b is mounted on the cap section 34Y in the manufacturing process , it can be difficult to do a job on the 34Y cap section in a complicated way. And a process time can increase. Thus, in the present first embodiment, the ID chip 35 (the substrate 35b) is detachably configured, and so there is a great effect as long as the data input/output operation can be performed on the ID chip 35 alone (or for each retaining member 34k) if necessary.
[0150] Referring to figures 17 and 27, in the cap section 34Y, a permanent member 34f is formed which locks the insertion opening 34k1 in the state where the retaining member 34k is mounted in the concave section.
[0151] Thus, a problem is prevented where the ID chip 35 disengages from the insertion opening 34k1 of the holding member 34k after the ID chip 35 (the holding member 34k) is mounted on the cap section 34Y.
[0152] Referring to Figure 2B, within the retaining member 34k (the box-like member), a first front section 34k4 and a second front section 34k5 are formed. The first front section 34k4 faces a first plane of substrate 35b (with reference to Figure 29, a surface on which the plurality of metallic buffers 35a is disposed) and is formed to only contact and slide in an outer peripheral area of the foreground. where the metallic buffers 35a are not arranged so as not to interfere with the plurality of metallic buffers 35a. The second front section 34k5 faces a substrate background 35b (with reference to Figure 29, a surface where the information storage unit 35c is disposed) and is formed to slide over part of the background so as not to interfere with the unit. information storage 35c. Thus, inside the holding member 34k, the ID chip 35 can move freely in the XZ plane (it can move to slide over the opposite sections 34k4 and 34k5) without disengaging from the holding member 34k, and without the dampers metals 35a or the information storage unit 35c being damaged.
[0153] In addition, openings 34k2 and 34k3 are formed in the front and rear surfaces of retaining member 34k, respectively. The first opening 34k2 is formed to allow a plurality of metallic buffers 35a and the positioning notch 35b1 to be exposed on the side face of the connector 73e even when the substrate 35b moves in the XZ plane to some extent. Thus, following the movement of the substrate 35b in the XZ plane, the positioning pin 73e3 and the notch 35b1 can be engaged with each other, and the metallic buffers 35a and the side terminals of the body 73e2 can be connected (contact com) with each other. Furthermore, the second opening 34k3 allows the information storage unit 35c to be exposed to the side face of the concave section of the lid section 34Y even when the substrate 35b moves about the XZ plane to some extent.
[0154] Referring to Fig. 28, the opening 34k2 formed in the front surface of the retaining member 34k is formed so that the left side has a convex shape and the right side has a concave shape. Thus, the area circled by a dotted line in Fig. 28 acts as a hook (a plug) to prevent the ID chip 35 from dislodging from opening 34k2.
[0155] Figure 29 is a three plane view illustrating the ID chip 35.
[0156] As illustrated in figure 29, the ID chip 35, the metallic buffers 35a as four metallic plates are arranged in a line in the Z direction in the foreground of the substrate 35b. The metallic buffer 35a has a multilayer structure having three layers of a copper layer, a nickel layer and a metallic layer which are arranged in order from the side of the substrate 35b, and the metallic layer as the surface layer is comparatively expensive, but willing to prevent oxidation. Metal damper 35a is formed by evaporation of the electric field on substrate 35b which is masked in advance.
[0157] Positioning notches 354b1 are formed on both end sections of the four metallic buffers 35a in the array direction, (the Z direction) to interpose the four metallic buffers 35a. In the present first embodiment, a first virtual straight line S1 which passes through the centers of the notches 35b1 and is parallel to the direction of the arrangement of the plurality of metallic buffers 35a is configured not to be positioned to overlap a second virtual straight line S2 which connects the centers of the plurality of metallic dampers 35a in the longitudinal direction. Specifically, the first virtual straight line S1 that connects the two positioning notches 35b1 (a virtual line connecting the centers of the original oblong holes in the notches 35b1 each of which is shaped like one half when the oblong hole is split into two in the longitudinal direction) is configured not to be positioned to overlap the second virtual straight line S2 connecting the centers of the plurality of metallic buffers 35a in the longitudinal direction. That is, in notches 35b1, the virtual straight line S1 connecting the sections that are more corroded towards the substrate 35b is not positioned to overlap the virtual straight line S2. Also, the virtual straight line S1 is configured to be almost parallel to the virtual straight line S2.
[0158] In the present first embodiment, the dimensions a to f in figure 29 are defined as 6.2 mm, 5.2 mm, 1.5 mm, 2 mm, 6 mm, and 11.7 mm, respectively. The substrate 35b having a small area size is small in amount of deviation even if external force is applied and comparatively large in strength (stiffness) characteristic against shear force. In the present first embodiment, the ID chip 35 is retained to be movable within the retaining member 34k, and a positioning method is employed in which the positioning pin 73e3 is inserted into the notch 35b1 and is likely to be "grasped" (a state where the positioning pin 73e3 enters the notch 35b1 obliquely rather than vertically, a sliding load between the notch 35b1 and the positioning pin 73e3 increases, and thus the substrate 35b is offset and does not move) in the case of ID 35 chip have large area size. However, since the substrate 35b has the small area size, the stiffness increases, and so the positioning method that is difficult to cause deviation that causes “sticking” is implemented. In addition, a gap between the metallic buffers 35a on the substrate 35b is narrow, but failure of contact between the metallic buffers 35a and the body side terminals 73e2 can be prevented by positioning with high accuracy in keeping with the movement of the substrate 35b on the XZ plane, and thus the area size of the expensive metallic buffers 35a having the metal layer can be suppressed to a minimum area size.
[0159] Figure 16 is a schematic perspective view illustrating the connector 73e on the body side of the apparatus 100.
[0160] Referring to Figure 16, the four side terminals of body 73e2 on connector 73e are plate-like (linear) metallic members, have one end as the fixed end and the other end as the free end, and are secured to and supported on the 73e1 connector body. At the other side ends of the end sides of the four side terminals of the body 73e2 are formed curved sections that curve towards the chip side of the ID 35 (32Y toner container). That is, the side terminals of the body 73e2 towards the ID chip 35 look like a knee (for a boomerang). The curved sections of the 73e2 body side terminals are sections that act as contact points with the 35a metal buffers.
[0161] Following the assembly operation of the 34Y cap section (the 32Y toner container) on the cap receiving section 73, the curved section of the body side terminal 73e2 contacts almost the center section of the metal bumper 35a in the longitudinal direction. Then, when the assembly operation of the cap section 34Y still proceeds, the ID chip 35 (the substrate 35b) approaches the connector side 73e, the side terminal of the body 73e2 is deformed so that the curved section of the terminal The side of the body 73e2 lies close to the first virtual straight line S1 while being compressed by a metallic shock absorber 35a and elastically deformed (a state in which a bent knee stretches). That is, in follow-up with the cover section assembly operation 34Y, the curved section of the body side terminal 73e2 slides in the left direction in figure 29 from the cover section in the longitudinal direction (addresses the first virtual straight line S1 ) while gradually increasing the contact pressure on the metallic shock absorber 35a.
[0162] Through the configuration described above, even if the position of the cap section 34Y (the metal damper 35a) in the longitudinal direction (the Y direction) is misaligned with the cap receiving section 73 (the side terminal of the body 73e2 ) depending on whether or not a degree of dimensional accuracy or a degree of assembly accuracy of an associated component is high or low (a variation of dimension), the contact failure between the body side terminal 73e2 and the metallic buffer 35a it can be prevented to a high degree. Finally, since the side terminal of the body 73e2 and the metallic bumper 35a come into contact with each other almost at the position where the positioning pin 73e3 is engaged with the notch 35b1 (almost the first virtual straight line S1), the distance between the positioning section and the contact section can be reduced. As a result, a degree of accuracy of the contact position between the side terminal of the body 73e2 and the metallic buffer 35a increases.
[0163] Furthermore, in the present first embodiment, the plurality of metallic dampers 35a is arranged in line in the direction of the arrangement which is the vertical direction.
[0164] As a result, the positioning direction of the cover section 34Y in the cover receiving section 73 (the arrangement direction of the positioning pins 73a and 73b and the positioning holes 34a and 34b) is the same as the direction of positioning the connector 73e and the substrate 35b (the arrangement direction of the positioning pin 73e3 and the notch 35b1), and thus the contact failure between the side terminal of the body 73e2 and the metallic buffer 35a is difficult to occur.
[0165] Referring to figure 21, the positioning holes 34a and 34b of the cap section 34Y are formed in position away from each other in the vertical direction to interleave the ID chip 35 (the information storage device). A third virtual straight line S3 connecting the centers of the two positioning holes 34a and 34b is configured to be parallel to the first virtual straight line S1 connecting the two positioning notches 35b1.
[0166] As described above, since the ID chip 35 is arranged to be fixed between the first positioning hole 34a (the main reference) and the second positioning hole 34b (the sub-reference), the position of the ID chip. ID 35 with respect to connector 73e of the cap receiving section 73 is decided with a high degree of accuracy. Thus, communication failure caused by misalignment in position between connector 73e and ID chip 35 can be suppressed. Particularly, since the direction of positioning the cap section 34Y on the cap receiving section 73 (the arrangement direction of the positioning pins 73a and 73b and the positioning holes 34a and 34b) is the same as the positioning direction of the connector 73e and substrate 35b (the arrangement direction of positioning pin 73e3 and notch 35b1), the operation of positioning the toner container 32Y in the body of the imaging apparatus 100 contributes to making it easier to position the substrate 35b in the connector 73e. As a result, there is an effect that failure of contact between the side terminal of the body 73e2 and the metallic buffer 35a is difficult to occur.
[0167] Furthermore, a procedure in which the components of the vial receiving section 72 and the cap receiving section 73 are related to the cap section 34Y when the operation of assembling the toner container 32Y in the storage unit toner container 70 proceeds, it is as follows.
[0168] First, the cap section 34Y slides over the vial receiving surface 72a, and thereafter the guide rail section 34e of the cap section 34Y is fitted into the engagement groove 73m of the cap receiving section 73, the side protrusion 34c of the cover section 34Y is fitted into the side slot 73h and the slot section 73r1 of the cover receiving section 73, and the posture of the cover section 34Y in the cover receiving section 73 in vertical directions. and horizontal is restricted. At this time, shaking of the cap section 34Y before being inserted into the cap receiving section 73 is prevented by the cap section intercalating member 73r. The first positioning hole 34a of the cap section 34Y is fitted into the main reference pin 73a of the cap receiving section 73, and thus the positioning of the main reference is effected. Thereafter, the second positioning hole 34b of the cap section 34Y is fitted into the sub-reference pin 73b of the cap receiving section 73, and thus main positioning and sub-positioning are completed. Furthermore, although the positioning is being completed, the state of contact between the plug section 34d22 of the plug member 34d of the cap section 34Y and the contact section 34n5 is released by the plug release stimulus section 72b, and the postures of shutter member 34d and cap section 34Y in cap receiving section 73 are decided by a body-side shutter closure mechanism (not shown). In this state, the opening operation of the shutter member 34d is performed. Toner discharge opening W open in cover section 34Y is communicated with toner feed opening 73w of cover receiving section 73. Slot 35b1 of ID chip 35 of cover section 34Y is engaged with pin of positioning 73e3 of the connector 73e of the apparatus body 100, the position of the ID chip 35 in the cap section 34Y is decided, and the plurality of metallic buffers 35a of the ID chip 35 come into contact with the plurality of side terminals of the body 73e2 of connector 73e, respectively, with a high degree of certainty. Thus, the attachment of the cover section 34Y (the toner container 32Y) to the cover receiving section 73 (the toner container storage unit 70) is completed. At this time, gear 33c of container body 33Y interlocks with drive gear 81 of apparatus body 100.
[0169] However, when extracting (removing) the 32Y toner container from the toner container storage unit 70 (the cover receiving section 73), the procedure contrary to the procedure at the time of assembly is performed.
[0170] As described above, in the imaging apparatus according to the present first embodiment, as the user performs an action of moving the toner container 32Y in the longitudinal direction while squeezing the clamping section 33d (excluding the opening operation /closing the body cover), the opening/closing operation of the toner discharge opening W by the shutter member 34d is also performed in conjunction with the operation, and the assembling operation and the removal operation of the toner container 32Y are completed.
[0171] Furthermore, in the 32Y toner container according to the present first embodiment, the toner discharge opening W having a comparatively large opening area size is disposed downwards in the vertical direction, and thus the toner can be discharged so that it falls directly from the toner discharge opening W by its own weight.
[0172] Furthermore, since the 32Y toner container is not placed from above the toner container storage unit 70 (the body of the apparatus 1000, but attached to or detached from the front surface of the toner storage unit toner container 70 (the machine body 100), a sketch degree of freedom above the toner container storage unit 70 increases. For example, even when a scanner (a document reading section) is placed directly above the Toner feeding device, operation or workability at the time of attaching/detaching the 32Y toner container does not deteriorate.
[0173] Furthermore, since the 32Y toner container is arranged in the apparatus body 100 so that the longitudinal direction is the horizontal direction, it has no influence on the overall outline of the imaging apparatus body 100 in the direction of height. The toner capacity of the 32Y toner container increases, so the replacement frequency may be reduced.
[0174] As described above, in the present first embodiment, the contact-type ID chip 35 (the information storage device) is retained in the retaining member 34k (the retaining section) to be movable about the virtual plane which is substantially orthogonal to the direction of movement in which the metallic buffers 35a (terminals) approach and contact the side terminals of the body 73e2. Thus, even when the contact-type ID chip 35 (the information storage device) is installed in the 32Y toner container (the removable device) detachably installed in the body of the imaging apparatus 100, the contact fails caused by the mismatch with the side terminals of the body 73e2 of the connector 73e of the body of the imaging apparatus 100 is difficult to occur. SECOND MODE
[0175] A second embodiment of the present invention will be described in detail with reference to figures 31 to 33.
[0176] Figure 31 is a schematic cross-sectional view illustrating a toner container 232Y according to the present embodiment. Figure 32 is a rear view illustrating a lid section 234Y of a toner container 232Y. Figure 33 is a perspective view illustrating a retaining cap 234k8 that is fitted within a retaining member 234k.
[0177] The toner container 232Y according to the present embodiment is different from the first embodiment in configuring the holding member 234k in a holding mechanism for holding the information storage device.
[0178] Similar to the first embodiment, the toner container 232Y according to the present second embodiment includes the container body 33Y and a lid section 234Y. The ID chip 35 as the information storage device is detachably installed in the cap section 234Y.
[0179] In the cap section 234Y according to the present embodiment, the retaining member 234k in which the part exposing the opening 34k2 of the ID chip 35 (the metallic buffers 35a and the notch 35b) is integrally formed.
[0180] The ID chip 35 is inserted from the inner side of the cap section 234Y in a direction of an arrow in figure 31 and fixed in a position of the retaining member 234k. In the state where the ID chip 35 is fixed in the position of the retaining member 234k, the retaining cap 234k8 is inserted from the inner side of the cap section 234Y in the direction of the arrow in figure 31 and fitted into the retaining member 234k (the state of figure 32).
[0181] In retaining cap 234k8, a pedestal section 234q that is fitted on retaining member 234k is arranged so as not to come in contact with substrate 35b.
[0182] In addition, the retaining cover 234k8 is securely installed without a gap with the inner wall of the cover section 234Y so as to prevent toner leakage from the toner container 232Y from adhering to the ID chip 35.
[0183] Even in the present second embodiment, the ID chip 35 (the substrate 35b) is retained in the retaining member 234k (and the retaining cap 234k8) to be movable about the XZ plane.
[0184] As described above, similarly to the first embodiment, even in the present second embodiment, the contact-type ID chip 35 (the information storage device) is retained in the retaining member 234k (the retaining section) to be movable over the virtual plane that is substantially orthogonal to the direction of motion in which the metallic dampers 35a (terminals) approach and contact the side terminals of the body 73e2. Thus, even when the contact-type ID chip 35 (the information storage device) is installed in the toner container 232Y (the removable device) detachably installed in the body of the imaging apparatus 100, the contact fails caused by the mismatch with the side terminals of the body 73e2 of the connector 73e of the body of the imaging apparatus 100 is difficult to occur. THIRD MODE
[0185] A third embodiment of the present invention will be described in detail with reference to figure 34.
[0186] Figure 34 is a schematic view illustrating a state in which the information storage device 35 of a toner container 332Y according to the present third embodiment is attached to connector 73e of the cap receiving section 73. 34 is a view corresponding to figure 27 in the first embodiment.
[0187] The present third embodiment is different from the first embodiment in that the cushion material 334k10 is installed within the retaining member 34k and a configuration of a wall section 373g of a cap receiving section 373 is different.
[0188] Similar to the above embodiments, a toner container 332Y according to the present third embodiment includes a container body 33Y and a cap section 34Y. The ID chip 35 as the information storage device is detachably installed in the tomb section 34Y. Furthermore, the ID chip 35 is retained in the 34k holding member to be mobile in the XZ plane.
[0189] In the present third embodiment, the cushion material 334k10 is disposed between the inner wall (the second front section 34k5) of the retaining member 34k and the substrate 35b. The 334k10 cushion material is made of an elastic material such as foamed polyurethane, and a low friction material adheres to a section facing substrate 35b. Thus, it is possible to alleviate the occurrence of damage to the substrate 35b when the positioning pin 73e3 is engaged with the notch 35b1 without impeding the movement of the ID chip 35 (the substrate 35b) in the XZ plane. In the present third embodiment, wall section 373g of cap receiving section 373 is installed to surround four sides of connector 73e. In order to deal with it, the concave section to avoid interference with the wall section 373g is formed in the cap section 34Y. By arranging the 373g wall section as described above, even if the toner is spread from the vicinity of the toner discharge opening W of the 332Y toner container to the outside, the scattered toner is difficult to adhere directly to the 73e connector or the chip of ID 35. Thus, the contact failure (the communication failure) between the connector 73e (the side terminal of the body 73e2) and the ID chip 35 (the metallic buffer 35a) caused by the scattered toner can be avoided.
[0190] As described above, similarly to the above embodiments, even in the present third embodiment, the contact-type ID chip 35 (the information storage device) is retained in the retaining member 34k (the retaining section) to be movable in the virtual plane that is substantially orthogonal to the direction of motion in which the metallic buffers 35a (terminals) approach and contact the side terminals of the body 73e2. Thus, even when the contact-type ID chip 35 (the information storage device) is installed in the toner container 332Y (the removable device) detachably installed in the body of the imaging apparatus 100, the contact fails caused by the mismatch with the side terminals of the body 73e2 of the connector 73e of the body of the imaging apparatus 100 is difficult to occur. FOURTH MODE
[0191] A fourth embodiment of the present invention will be described in detail with reference to figure 35.
[0192] Figure 35 is a three plan view illustrating a substrate 435b of an information storage device 435 according to the present fourth embodiment. Figure 35 is a view corresponding to Figures 14A and 14B in the first embodiment.
[0193] Similar to the above embodiments, a toner container (432Y) according to the present fourth embodiment also includes container body 33Y and cap section 34Y. The ID chip 435 as an information storage device is detachably installed in the cap section 34Y. Furthermore, the 435 ID chip is retained in the 34k holding member to be mobile in the XZ plane.
[0194] On a substrate 435b of the ID chip 435 according to the present third embodiment, instead of the positioning notch 35b1 in the above embodiments, the positioning holes 435b11 and 435b12 are arranged. Following the toner container assembly operation (432Y), substrate 435b moves freely in the XZ plane, and positioning holes 435b11 and 435b12 are engaged with positioning pins 73e3 of connector 73e. Specifically, the edges (or inner surfaces) of holes 435b11 and 435b12 contact positioning pins 73e3, and movement of substrate 435b is restricted. Thus, contact failure caused by misplacement between the plurality of metallic buffers 35a and the side terminals of body 73e2 of connector 73e is difficult to occur.
[0195] In the present fourth embodiment, in view of the fact that the substrate 435b is positioned on the underside of the retaining member 34k due to the weight of the substrate 435b directly before the positioning holes 435b11 and 435b12 are engaged with the positioning pins 73e3 , circular hole 435b11 is formed in the lower section of substrate 435b, and elliptical hole 435b12 is formed in the upper section of substrate 435b. Hole 435b11 in the bottom section is caught by positioning pin 73e3, so substrate 435b is lifted, and positioning pin 73e3 is smoothly inserted into the other elliptical hole (hole 435b12). If the hole in the bottom section is the elliptical hole and the hole in the top section is the circular hole, the 435b substrate may not be lifted by the positioning pin 73e3, and the positioning pin 73e3 may be difficult to insert into the circular hole in the top portion.
[0196] In the present fourth embodiment, the two positioning holes 435b11 and 435b12 are formed in the substrate 35b of the ID chip 35. On the other hand, in the substrate 435b of the ID chip 435, one can be formed of the positioning holes 435b11 ( or 435b12), and the other can be formed from positioning notch 35b1 (which was used in the above modalities). Even in this case, the same effect as in the present fourth modality can be obtained.
[0197] As described above, similarly to the above embodiments, even in the present fourth embodiment, the contact-type ID chip 435 (the information storage device) is retained in the retaining member 34k (the retaining section) to be movable in the virtual plane that is substantially orthogonal to the direction of motion in which the metallic buffers 35a (terminals) approach and contact the side terminals of the body 73e2. Thus, even when the contact-type ID chip 435 (the information storage device) is installed in the toner container (the removable device) detachably installed in the body of the imaging apparatus 100, the contact failure caused by misplacement with the side terminals of the body 73e2 of the connector 73e of the body of the imaging apparatus 100 is difficult to occur. FIFTH MODE
[0198] A fifth embodiment of the present invention will be described in detail with reference to figures 36 to 41.
[0199] Figure 36 is a view in three planes illustrating a substrate of an information storage device 535 according to the present fifth embodiment and is a view corresponding to Figure 29 in the first embodiment. Fig. 37 is a perspective view illustrating information storage device 535, a retaining member 534k (534k25), and a connector 573e, and is a perspective view illustrating a relative positional relationship of the three members 534k (534k25), 535 and 573e. Fig. 38 is a perspective view illustrating a condition where information storage device 535 is engaged with connector 573e. Figures 39A and 39B are circuit diagrams illustrating an electrical circuit of information storage device 535 and an electrical circuit of connector 573e. Figure 40A is a front view illustrating a condition where the information storage device 535 is retained in the connector 573e, and Figure 40B is a front view illustrating a condition where the information storage device 535 is rotating in an orifice. positioning 535b21. Fig. 41 is a view illustrating information storage device 535 that contacts probe 400 in an inspection process when manufactured in a factory.
[0200] The present fifth embodiment is different from the first to fourth embodiments in that only one positioning hole 535b21 is formed in the substrate 535b of the information storage device 535, and the positioning hole 535b21 is disposed between a plurality of metallic buffers 35a1. , 35to2 and 35to3 rectangular (metallic shock absorbers).
[0201] Referring to Fig. 36, the ID chip 535 as the information storage device according to the present fifth embodiment has the positioning hole 535b21 which is formed in the upper position in the vertical direction farther than the center of substrate gravity 535b. A metallic ground terminal 535d is disposed on an inner surface of hole 535b21 and around hole 535b21. In the present fifth embodiment, the metal terminals 535d formed on the surface of the substrate 535b include two protruding sections 535d1 that are formed to extend from a rink-like section in the horizontal direction.
[0202] In addition the rectangular 35a1 metal bumper is installed above the 535b21 positioning hole in the vertical direction, and the two rectangular 35a2 and 35a3 metal bumpers are installed below the 535b21 positioning hole in the vertical direction.
[0203] Furthermore, on the back side of the substrate 535b (the side facing the lid section 34Y), a protective member 535e which is made of a resin material having a substantially hemispherical shape or an inverted pan shape such as epoxy and copper information storage unit is arranged. In the present fifth embodiment, although it depends on the shape of the substrate 535b or the configuration/arrangement of the rear surface such as the shielding member 535e, with the hole 535b21 above the shielding member 535e which may include the information storage unit such as a integrated circuit (IC) inside and is a heavier component, a positional relationship in which the hole 535b21 is installed vertically above the center of gravity of the ID chip 535 is implemented. Specifically, with reference to Fig. 40A, the ID chip 535 (the information storage device) according to the present fifth embodiment is formed so that the central position of the positioning hole 535b21 is at distance Za above the center of gravity. of the 535 ID chip.
[0204] Referring to Figure 37, connector 573e includes a connector body 573e21 that is made of resin and is a hollow box, and a positioning pin 573e23 (a positioning protruding section) that is a hollow cylinder and having a tapered tip is disposed on the 573e21 connector body to remain in the horizontal direction. A 573e25 body side ground terminal (a ground terminal) is installed on the 573e23 positioning pin. The 573e25 body side ground terminal is a map-like (or linear) metallic member, partially housed in the hollow section of the 573e23 positioning pin formed integrally with the 573e21 connector, and has a curved section that is exposed from a similar opening. the slit formed in part of the circumferential surface of the hollow cylinder and protrudes from the outer circumferential cylindrical surface. In addition, one side terminal of body 573e2 is installed vertically above positioning pin 573e23 (0 side ground terminal of body 573e25), and two side terminals of body 573e2 are installed vertically below positioning pin 573e23 (the side ground terminal of body 573e25). The side terminals of the 573e2 body are map-like (or linear) metallic members and are formed in much the same way as in the above embodiments except that the installation position is different.
[0205] In addition, swing prevention members 573e24 as a pair of guide members protrude from the right and left sides of the positioning pin 573e23. The guiding members include a pair of plates whose tips have inner tapered surfaces facing each other and orientation for both sides of the ID 535 chip to be perpendicular.
[0206] Similar to the above embodiments, the holding member 354k (the holding section) is fixed to a toner container (532Y) and positioned between the connector 573e and the ID chip 535. The holding member 534k has nearly a same function (a function to mobile hold the ID chip 35) as in the above modalities. Referring to Fig. 37, retaining member 534k in accordance with the present fifth embodiment has a first front section 534k24 which is configured to be linearly symmetric about a central axis in the vertical direction and is formed to cover an area of the two upper corners of the 535 ID chip on both sides of the 535b21 hole. Retaining member 534k is formed to cover the lower section of substrate 535b than lower metallic buffer 35a3, and through the configuration described above, ID chip 535 is prevented from falling out of retaining member 534k.
[0207] Further, in retaining member 534k, the first front section 534k24 including an area facing the four side terminals of body 573e2 and 573e25 of connector 573e is formed of an opening. Particularly, in the retaining member 534k, an aperture 534k22 is formed which is open to a section corresponding to a pair of swing prevention members 573e24. At the time of assembling the toner container 532Y, the positioning pin 573e23 is inserted into the opening 534k22, and thereafter the pair of swing prevention members 573e24 (the pair of guide members) is also inserted into the retaining member 534k through of the opening 534k22.
[0208] A second front section 534k25 of a flat plate form facing the rear surface of the ID chip 535 (the 534k retaining member side) is secured to the 534k retaining member by adhesion or a snap fit (not shown ). The second front section 534k25 includes an opening 534k26 similar to the opening 534k22 and thus can avoid interference with the retaining members 535e or the inserted sway prevention member 573e24. However, when the 573e23 positioning pin is inserted into the 535b21 hole of the 535 ID chip, the 535 ID chip is pushed, but since the 534k25 second front section supports the 535b substrate from the back side, the contact condition between the terminals can be maintained.
[0209] Figure 38 is a schematic perspective view illustrating the condition where the positioning of the connector 573e and the ID chip 535 on the body side of the apparatus 100 is completed. The condition is that the toner container 532Y according to the fifth embodiment is mounted on the apparatus body 100, and the body side terminals 573e2 and 573e25 are connected with the aforementioned metallic buffers 35a1 to 35a3 and the ground terminal 535d. In Fig. 38, for reasons of easy understanding, the retaining member 534k (534k25) between the connector 573e and the ID chip 535 and the metallic buffers 35a1 to 35a3 are omitted.
[0210] When mounting the toner container 532Y on the body of the imaging apparatus, the main and subordinate positioning holes 34a and 34b of the cap section 534Y are fitted within the subordinate positioning pins 73a and 73b of the receiving section of cap 73, and the positioning of cap section 534Y is performed. This mount operation is the same as the mount operation of the first mode. After the position of cap section 534Y is decided, hole 535b21 of ID chip 535 is fitted within positioning pin 573e23 to be caught by the tapered end of positioning pin 573e23 of connector 573e. As a result, the position of the 535 ID chip in the horizontal direction and the vertical direction is decided at the same time. Furthermore, as illustrated in Figure 40A, the preventing members 573e24 (the pair of guiding members) of the connector 573e that includes the pair of plates are inserted into the lower edge portions that are on both the right and left sides of substrate 535b and in the lower area farthest from the center of hole 535b21. At this point, there is a possible case where the ID chip posture is misaligned as illustrated in Fig. 40B. Even in this case, if the inner tapered surfaces of the plates come into contact with the lower edge parts, they cause the 535b substrate to rotate in one direction to have the posture to be vertical by the action of the center of gravity, and the misalignment of posture in the direction of rotation (rotation in one direction of an arrow illustrated in figure 40B) is corrected (becomes a condition of figure 40A). Thus, the positioning of the 535 ID chip is complete. At this time, part of each terminal 535d of the 535 ID chip (a section corresponding to the inner surface of the 535b21 hole) contacts the side terminal of the 573e25 body of the 573e23 positioning pin illustrated in Figure 38, and the 535 ID chip is grounded (driving). Furthermore, after earth is connected, the three metallic buffers 35a (35a1, 35a2 and 35a3) of the ID chip 525 also come into contact with the three side terminals of the 573e2 body of the 573e connector, respectively, and thus information can be transmitted between the ID chip 535 and the side connector of the body 573e (the body of the apparatus 100).
[0211] As described above, in the present fifth embodiment, a high-precision positioning mechanism is implemented by an inexpensive setup adding various ideas such as the following ideas (1) to (5).
[0212] (1) Only one 535b21 positioning hole for the 535 ID chip needs to be positioned. Thus, the 535b substrate perforation processing time in fabrication becomes shorter than type ID chip for two positioning holes, and fabrication cost can be reduced.
[0213] (2) The 573e25 body side ground terminal is integrally installed on the lateral circumferential surface of the 573e23 positioning pin. Thus, the distance becomes the positioning pin 573e23 and the side terminal of the body 573e25 can become true zero (0), and a degree of accuracy of the position of the ground terminal 535d with respect to the side terminal of the body 573e25 can increase .
[0214] (3) In the finished assembly condition of figure 38, the positional relationship between the hole of PEC 535b21 and the curved sections of the side terminals of the body 573e2 is adjusted to match the center of the hole of the hole 535b21 with the line connecting the curved sections (connection sections) of the three side terminals of the 573e2 body on the 573e connector side. Thus, the distance in the horizontal direction from hole 535b21 as the positioning section on the contact sections can be reduced to approximately 0 mm. As a result, when the three metallic bumpers 35a1, 35a2 and 35a3 come into contact with the side terminals of the 573e2 body, a degree of position accuracy is improved.
[0215] (4) A plurality of metallic buffers 35a1, 35a2 and 35a3 are aligned, and the positioning hole 535b21 is disposed in any two spaces formed between two or three aligned buffers. Thus, compared to another arrangement-type ID chip where the hole is arranged on the underside or on the upper side on the outside of a row of the plurality of metal dampers 35a1, 35a2 and 35a3, the distance (which corresponds to the length of the arms of the pendulum) from the center of the positioning hole 535b21 to the farthest metal damper 35a can be reduced. Specifically, in the other type, the length of the arms becomes the distance corresponding to the three metallic buffers from the center of the hole. However, in the present fifth embodiment, the length of the arms can be the distance corresponding to the metallic shock absorbers. Since the length of the pendulum arms is short, even if the parallelism of the farthest metal damper 35a at the side terminal of the body 73e2 is misaligned due to, for example, variability in mass production, the misalignment can be suppressed for a Minimum.
[0216] (5) When a user stores the toner container in some space outside the imaging apparatus, a foreign substance can enter the holding member 534k and thus the holding position between the ID chip 535 and the sections 534k24 and 534k25 front ends may remain misaligned. In this problem, in the present fifth embodiment, the positional relationship between the hole 535b21 and the center of gravity of the ID chip 535 is improved. Hole 535b21 is disposed vertically above the center of gravity of the ID chip 535. Thus, when the pair of wobble preventing members 573e24 is inserted below hole 535b21 which is the center of rotation, substrate 535b contacts the tapered tips of the sway prevention members 573e24. Then, the posture of the 535 ID chip is stimulated to rotate in the vertical direction by the force of gravity and is corrected to be perpendicular. As a result, even if there is a positioning hole 535b21, a degree of position accuracy of the plurality of metallic buffers 35a1, 35a2 and 35a3 on the plurality of side terminals of the body 573e2 can be increased at the same time.
[0217] Depending on a number of produced plans to be made, there is a possibility that it is determined that the driving inspection device has a durability margin. In this case, inspection can be conducted using an inspection device having a configuration similar to the connector on the body of the imaging apparatus 100, i.e., inserting a conduction probe into the hole in which the ground terminal 535d is formed. In this case, as in a modification to the ID chip illustrated in Fig. 87, a circular ground terminal that does not include the protruding sections 535d1 can be employed. The same also applies to a case where a manufacturing method where conduct inspection is omitted based on improvement in the production process is employed. With this modification, the area of the metallic members can be reduced and the manufacturing cost can be reduced. In Fig. 87, the ID chip is illustrated assumed to be of a type in which no protective member is provided in the IC circuit on the rear surface and therefore the IC circuit is exposed. If the manufacturing environment, etc. allows absence of protection member, ID chip is useful for cost reduction. Although any sketch is available as long as the IC circuit stays out of both the left and right areas for smooth glide, it is preferable to arrange a relatively large IC in a lower section so that the center of gravity is located in a lower position.
[0218] Furthermore, if the earth connection probe is a pin, it is permissible to provide, as illustrated in figure 88A, a protruding section with which the earth probe 401 contacts. For ease of inspection, the modification illustrated in figure 88B which has an enlarged probe contact section may be employed. This is particularly useful in a case of manual inspection. The modification illustrated in Fig. 88C which does not have a circular frame but a square frame can also be employed. Any of the modifications of Figures 88A, 88B and 88C are designed so long as the outer circumferential area of the terminal formed in the hole remains outside both the left and right sliding areas. The rear surfaces of the ID chip of figures 88A, 88B and 88C can be either covered by the shield member or uncovered.
[0219] As described in ideas (1) to (5) described above, each of the five ideas can provide each function effect, and even if an expensive configuration where the area size of the metallic buffer 35a becomes minimal is employed, it is possible to greatly increase a degree of positioning accuracy between the plurality of terminals 35a1, 35a2 and 35a3 and 535d including a ground terminal on the ID chip 535 and the plurality of body side terminals 573e2 and 573e25.
[0220] In addition, in this fifth modality, ideas and function effects other than those described above will be described.
[0221] First, each of the metallic shock absorbers 35a1, 35a2 and 35a3 is described. The 35a1 metal damper, which is at the highest level, receives a clock signal for communication control. Although a serial communication method that is low speed but high cost, because sequential data transfer is employed and an I2C (interintegrated circuit) is employed as a serial bus, the 35a1 metal damper forms a signal line in which a serial clock (SCL) is introduced when the signal line is connected to the body side connector. Metal dampers 35a1 correspond to a terminal in which the clock signal is introduced. Because a clock signal flows unidirectionally, the possibility of the 535 ID chip is expected to break if a short circuit occurs between the 35a1 metal damper and a Vdc described later (the power supply or the 35a3 metal damper) than between the other terminals and the Vcc. Therefore, to prevent breakage of the 535 ID chip, the 35a1 metal damper is arranged further away from the Vcc. This is because the possibility of breakage is less if a short circuit occurs between the metallic buffer 35a1 and the GND (ground terminal 535d).
[0222] The 35a2 metal damper 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 signal line is connected to the connector on the side of the body. Because this snubber has a bidirectional input/output mechanism, the possibility that the 535 ID chip breaks due to a short circuit is less than the possibility due to the 35a1 unidirectional metallic input snubber.
[0223] The 35a3 metal damper forms a power input portion (Vcc) into which a voltage of 5V or a voltage of 3.3V is introduced when it is connected to the body side connector. To reduce the risk of disruption of the entire device due to a short circuit between the power supply and the GND, the serial data input terminal (the 35a2 metal buffer) is arranged between the GND (the 535d ground terminal) and the serial clock input terminal (the 35a1 metal damper). As illustrated in Fig. 36, the Vcc or metallic buffer 35a3 overlaps with the shield member 535e which is on the back side of the ID chip such that the substrate 535b is between them; therefore, the 35a3 metal damper is close to an IC drive circuit included in the 535e protection member. With this arrangement, a short thick line can be used as a power supply line which enables stable power supply operations (= suppression of malfunction due to noise).
[0224] Second, ideas for land are described. In the 532Y toner container assembly operation, the 535d earth terminal of the 535 ID chip contacts the 573e25 side earth terminal of the 573e23 positioning pin (the 573e connector), and then the three metallic buffers 35a1, 35a2 and 35a3 of the 535 ID chip begin to contact the three side terminals of the 573e2 body of the 573e connector. That is, in the detachment operation of the toner container 532Y, the contact between the three metallic buffers 35a1, 35a2 and 35a3 of the ID chip 535 and the three side terminals of the body 573e2 of the connector 73e is released, and then the ground terminal 535d of the ID chip 535 is released from the condition of contacting (separated from) the body side ground terminal 573e25 of positioning pin 573e23 (the 573e connector). Specifically, with reference to Fig. 39A, the side ground terminal of body 573e25 at connector 573e has the closest contact start position to ID chip 535 than the three side terminals of body 573e2.
[0225] Despite the configuration described above, in the 532Y toner container assembly operation, the 35a1, 35a2 and 35a3 metal buffers always start to be connected with the side terminals of the 573e2 body in the condition where the 535 ID chip is grounded , and in the detachment operation of the toner container 532Y, the metallic buffers 35a1, 35a2 and 35a3 always start to separate (released from the condition of contact with) the side terminals of the 573e2 body in the condition that the 535 ID chip is grounded . Thus, an electrical circuit on the 535 ID chip is prevented from being grounded and thus becoming an electrically floating condition, and thus the 535 ID chip is difficult to be electrically damaged.
[0226] In detail, when the electrical circuit in the ID 535 chip is ungrounded and becomes an electrically floating condition, the electrical circuit becomes a condition that is grounded with very large impedance. If static electricity, which is generated when metal dampers 535a come into contact with or are separated from the side terminals of body 573e2, flows lightly into the electrical circuit, a high voltage that is the same as the impedance applied to the current is generated. The high voltage causes the insulation inside the IC in the ID 535 chip to break, and so the IC is broken. This problem easily occurs when the contact start positions of the three side terminals of the body 573e2 and the side ground terminal of the body 573e25 on the ID chip 535 are formed in the same position with respect to the connector 573e, as illustrated in Fig. 39B.
[0227] On the other hand, in the present fifth embodiment, the curved section of the side ground terminal of the body 573e25 exposed from the slot-like opening of the positioning pin 573e23 is arranged to be closer to the ID chip 535 than the section curved from the side terminal of the 73e2 body that protrudes more towards the side of the ID chip 535. Thus, since the ground is first connected, and at the time of separation and the ground is last disconnected at the time of contact, the impedance is always theoretically zero, and even if static electricity flows into the electrical circuit, breaking the insulation inside the IC is prevented.
[0228] Furthermore, in the ID chip 535 (the information storage device) according to the present fifth embodiment, the two protruding sections 535d1 are disposed over part of the outer circumference of the ground terminal 535d as described above with reference to the figure 36.
[0229] Since the 535d1 protruding sections are arranged on the front surface of the 535b substrate of the 535 ID chip as described above, in the inspection process (a process of inspecting whether or not the 535 ID chip is defective) at the time of manufacture in a factory, an operation of contacting a driving inspection probe can be easily performed. In detail, as illustrated in Fig. 41, the leading ends of a plurality of probes 401 of a driving inspection device 400 are pressed down against the metallic buffers 35a and the ground terminal 535d of the ID chip 535 placed in a table of inspection. At this time, since the protruding section 535d1 of the ground terminal 535d has an area that can sufficiently come into contact with the leading ends of the probes 401, a conduct inspection failure caused by a contact failure of the probes 401 can be prevented. Furthermore, since the conduction inspection is carried out by pressing the main end sections of the probes 401 down against the ground terminal 535d (the protruding section 535d1), compared to when the conduction inspection is carried out by inserting the probes 401 into the hole 535b21 , a resistance characteristic of probes 401 that are repetitively used for inspection can be improved, and a problem where the 535b21 hole of the 535 ID chip wears out by conduction inspection can be prevented.
[0230] In an excess space widening in a wedge shape between the annular earth terminal 535d and the rectangular 35a1, 35a2 metallic buffer, the protruding section 535d1 has a horizontal direction boundary (boundary line) that contacts the outer circumference annular and is arranged to be parallel to the 35a1, 35a2 and 35a3 metal dampers. Thus, the protruding section 535d1 does not protrude in the vertical direction, the protruding section 535d1 can be prevented from protruding to the left and the sliding areas of the substrate 535b that slide against the first front section 534k24 (protruding in the horizontal direction) . As a result, the size of the 535b substrate does not increase, and at the time of manufacture, it is possible to obtain as many 535b substrates as possible from a substrate material having the standard size. Also, the cost of the 535 ID chip can be suppressed from increasing.
[0231] As described above, similarly to the above embodiments, even in the present fifth embodiment, the contact-type ID chip 535 (the information storage device) is retained in the holding member 534k (the holding section) to be movable in the vertical plane that is substantially orthogonal to the direction of movement in which the metallic buffers 35a1, 35a2 and 35a3 (terminals) approach and contact the lateral terminals of the body 573e2. Thus, even when the contact-type ID chip 535 (the information storage device) is installed in the toner container 532Y (the removable device) detachably installed in the body of the imaging apparatus 100, the contact fails caused by the mismatch with the 573e2 body side terminals of the 573e connector is difficult to occur.
[0232] Furthermore, in the present fifth embodiment, even when the contact-type ID chip 535 (the information storage device) is installed in the toner container 532Y (the removable device) detachably installed in the body of the device imaging 100, provided that the ground terminal 535d that is engaged with the side ground terminal of the body 573e25 formed on the positioning pin 573e23 (the protruding section) of the connector 573e (the body of the imaging apparatus 100) is formed in a 535b21 hole formed in the 535b substrate of the 535 ID chip, the 535 ID chip is difficult to be electrically damaged. SIXTH MODE
[0233] A sixth embodiment of the present invention will be described in detail with reference to figures 42A to 47C.
[0234] Figures 42A and 42B are perspective views illustrating a toner container 632Y according to a sixth embodiment. Particularly, Fig. 42A is an exploded view illustrating a state in which the ID chip 535 described in the fifth embodiment is not assembled, and Fig. 42B is a view illustrating a state in which the ID chip 535 is assembled. Fig. 43 is a front view illustrating the toner container 532Y in which the face plate 634p is not installed and is a view corresponding to Fig. 21 in the first embodiment. Fig. 44 is a cross-sectional view illustrating a main part of toner container 632Y in which the ID chip 535 and face plate 634p are installed. Fig. 45 is a view illustrating a state where ID chip 535 is inserted into connector 573e.
[0235] In the present sixth embodiment, the ID chip 535 as the information storage device is the same as in the fifth embodiment. The present sixth embodiment is different from the fifth embodiment in that the ID chip 535 is loosely retained in a concave section disposed in a cap section 634Y and movably covered by face plate 634p, and the remaining configuration is the same as in the fifth modality.
[0236] Similar to the above embodiments, the toner container 532Y according to the present sixth embodiment also includes the toner container 532Y and the cap section 634Y. The ID chip 535 as the information storage device is detachably installed in the cover section 634Y.
[0237] With reference to figures 42A and 42B, in the present sixth embodiment, the ID chip 535 is not installed in the cap section 534Y in a state where it is loosely inserted into the retaining member 534k, and the failure prevention face 634p is screw-coupled to cover section 634Y in a state where the ID chip 535 is loosely retained in the concave section (where the pedestal section 634q is formed) formed in the cover section 634Y .
[0238] In detail, referring to figure 42A and figure 43, the concave section for holding the ID chip 535 to be movable in the XZ plane is formed on the end surface of the cap section 634Y. In the concave section, the pedestal section 634q is formed which contacts part of the ID chip 535. In the state where the ID chip 535 is loosely retained in the concave section of the cover section 634Y, the face plate 634p to predict the 535 ID chip from falling out of the concave section is fixed. With reference to Fig. 42B, Fig. 43B and Fig. 44, the face plate 634p is screw-coupled to contact part of the substrate 35b of the ID chip 35 in the state where the metallic buffers 35a1, 35a2 and 35a3, the hole of positioning terminal 535b21 (the ground terminal 535d), and the other of the ID chip 535 formed similarly to the fifth mode are exposed.
[0239] In more detail, in the cover section 634Y, a positioning pin 634s1 for positioning the face plate 634p is formed on the right side of the concave section, and a screw hole 634s2 for screwing the face plate 634p is formed to the left of the concave section with the concave section interposed between them. Meanwhile, in face plate 634p, a positioning hole 634p1 is formed in position corresponding to positioning pin 634s1, and a hole 634p2 through which a screw 680 passes is formed in position corresponding to screw hole 634s2. In the lower section of the face plate 634p, a contact section 634p3 that contacts the outer circumferential edge of the second positioning hole 34b and functions as a rotation plug is formed. The position of face plate 634p with respect to cover section 634Y is decided by positioning hole 634p1 and contact section 634p3 to stop rotation. Screw 680 is screwed into screw hole 634s2 formed in cover section 634Y through hole 634p2 formed in face plate 634p, and thus face plate 634p is secured to cover section 634Y. Thus, the ID chip 535 does not fall off the cover section 634Y and is retained in the cover section 634Y to be movable in the XZ plane. Referring to Fig. 45, similarly to the fifth embodiment, following the 632Y toner container assembly operation, the positioning hole 535b21 (the ground terminal 535d) of the ID chip 535 is engaged with the positioning pin 573e23 (the side earth terminal of the body 573e25) of the connector 573e of the body of the apparatus 100, after that the side terminal of the body 573e2 of the connector 573e comes into contact with the metallic buffers 35a1, 35a2 and 35a3 of the ID chip 535, and thus the electrical contact between the 573e connector and the 535 ID chip is completed. In this case, since the ID chip 535 in the lid section 634Y of the 632Y toner container is held to be movable in the XZ plane, similarly to the above modalities, the contact failure caused by the positioning failure with the side terminals of the body 73e2 and 573e25 of connector 573e of apparatus body 100 is difficult to occur. In the normal state, the ID chip 535 remains below the underside of the concave section of the cap section 534Y due to gravity, and the center position of hole 532b21 of the ID chip 535 is misaligned down to the center axial position of the pin. positioning 573e23 as the leftmost among the three 535 ID chips illustrated in Figure 45.
[0240] Then, when the 632Y toner container assembly operation starts and the ID chip 535 contacts the positioning pin 573e23, the IDS chip 535 moves up (in the Z direction) (is retracted) so that hole 535b21 follows the tapered main end section of positioning pin 573e23, hole 535b21 is fitted into positioning pin 573e23, and finally the side terminals of body 573e2 come into contact with metal bumpers 35a1, 35a2 and 35a3.
[0241] In the present sixth embodiment, the face plate 634p is fixed (screw-coupled) to the cover section 34Y by the screw 680.
[0242] On the other hand, as illustrated in figures 46A and 46B, the face plate 734p can be attached to a cover section 734Y with retainer attachment. In detail, as illustrated in Fig. 46A, a plurality of detent engaging engagement sections 734p2 are formed on the outer circumferential section of the face plate 734p, and detent engaging engagement sections 734s2 are formed at the positions of the cap section 734Y corresponding to them. As illustrated in Fig. 46B, in the state where the ID chip 535 is loosely inserted into the concave section of the cover section 734Y, the face plate 734p is secured with retention to the cover section 734Y. In more detail, while aligning a hole 734p3 formed in face plate 734p with a positioning bulge section 734s3 formed in cap section 734Y, engagement section 734p2 of phase plate 734p is engaged with engaged section 734s2 of end section cover 734Y, and face plate 734p is positioned and secured to cover section 734Y. Even in the case of this configuration, the same effect as in the sixth modality can be obtained.
[0243] Furthermore, in the present sixth embodiment, as long as the replacement can be made against, even after the 634p face plate (or the 734p face plate illustrated in Figures 46A and 46B) is mounted, the toner container can be manufactured by a procedure in which the toner container and face plate manufactured by a foreign partner company are first imported and then, within the country, after or before a process of loading the toner container with the toner, the chip ID 535 acquired from another company is assembled, and the toner information is inputted into the ID 535 chip. Thus, the manufacturing process of the toner container can be carried out efficiently.
[0244] In addition, a recycling process of collecting the used toner container from the market and charging the toner again after cleaning can be performed by a procedure of replacing the 535 ID chip or removing the 535 ID chip from the toner container , rewrite the information, and mount the 535 ID chip in the cap section again. Thus, the process of reusing the toner container can be carried out efficiently.
[0245] However, with reference to figure 47C (which is a cross-sectional view illustrating a cover section 834Y on which the ID chip 535 is mounted), when it is desired to increase a mounting resistance between the face plate 834p and a cover section 834Y without needing to remove the ID chip 535, only the positioning cup 734s3 (eg see figures 46A and 46B) can be arranged on the cover section without arranging the screw-coupling mold or the shape for quick fitting. Then, after the 535 ID chip and the 834p face plate are mounted on the 834Y cover section, the leading end of the 734s3 positioning cup can be thermally fused to secure the 834p face plate to the 834Y cover section, or an adhesive can be coated between face plate 834p and cover section 834Y to secure face plate 834p to cover section 834Y.
[0246] As described above, in the present sixth embodiment, the contact-type ID chip 535 (the information storage device) is retained in the cap section 634Y, 734Y or 834Y to be movable in the virtual plane that is substantially orthogonal to the direction of movement in which the 35a1, 35a2 and 35a3 metal bumpers (terminals) approach and contact the side terminals of the 573e2 body. Thus, even when the contact-type ID chip 535 (the information storage device) is installed in the 632Y, 732T or 832Y toner container (the removable device) movably installed in the body of the imaging apparatus 100, contact failure caused by the mismatch with the side terminals of the body 573e2 of the connector 573e of the imaging apparatus body 100 is difficult to occur.
[0247] Furthermore, still in the present sixth embodiment, similarly to the fifth mode, even when the contact-type ID chip 535 (the information storage device) is installed in the 632Y toner container (the removable device) so installed removable in the body of the imaging apparatus 100, provided that the ground terminal 535d is engaged with the side ground terminal of the body 573e25 formed on the positioning pin 573e23 (the protruding section) of the connector 573e (the body of the imaging apparatus 100 ) is formed on the 535b substrate of the 535 ID chip, the 535 ID chip is difficult to be electrically damaged.
[0248] Figures 47A and 47B are views illustrating a toner container 932Y of another embodiment. Particularly, Figure 47A is a front view illustrating a cover section 934Y on which the ID chip 535 is mounted, and Figure 47B is a front view illustrating the cover section 934Y and the ID chip 535 before the ID chip be mounted. In the toner container 932Y illustrated in figures 47A and 47B, unlike the above embodiments, the ID chip 535 (the information storage device) is attached to and retained in the cap section 934Y (held to be immobile in the XZ direction). Specifically, a concave section of the lid section 934Y (a section surrounded by a dotted line in Fig. 47B) is formed in a shape according to an outer circumferential shape of the ID chip 535 so that the ID chip 535 can be adjusted. inside it (adjusted in the same over a range of dimension variation by an adjustment tolerance of approx. 0.3 mm maximum, even if under agitation). In this case, unlike the above modalities, the 535 ID chip cannot move in the XZ plane, but the working effects of ideas (1) to (4) among the five ideas (1) to (5) described in fifth modality can be obtained. That is, as long as a positioning hole 535b21 in which the ground terminal 535d is formed is installed in the ID chip 535, the effects described in the fifth embodiment can be obtained. SEVENTH MODE
[0249] A seventh embodiment of the present invention will be described in detail with reference to figures 48 and 49. Figure 48 is an exploded perspective view illustrating a toner container 1032Y according to the seventh embodiment. Fig. 49 is a cross-sectional view illustrating toner container 1032Y.
[0250] The toner container according to the present seventh embodiment is different from the above embodiments in that the container body 33Y is rotatably held in the toner container storage unit 70 wherein a container body 1033Y is combined with any one of the cap sections 634Y, 734Y, 834Y, and 934Y illustrated in the sixth embodiment is non-rotatably retained in the toner container storage unit 70 along with the cap section.
[0251] With reference to figures 48 and 49, similarly to the above embodiments, the toner container 1032Y according to the present seventh embodiment mainly includes the container body 1033Y (the bottle body) and the cap section 634Y installed in the section of the same head (or the 734Y, 834Y or 934Y cap section and other shape). Hereinafter, the cap section in accordance with the present seventh embodiment will be described using cap section 634Y described with reference to figures 42A and 42B in the sixth embodiment.
[0252] Unlike the above embodiments, in the toner container 1032Y according to the present seventh embodiment, the container body 1033Y (the bottle body) is attached to the cap section 634Y by a fastening method, for example, it adheres a (merges with) or is engaged with cap section 634Y (the container cap). That is, the container body 1033Y is non-rotatably attached to the cap section 634Y.
[0253] Unlike the above embodiments, in the container body 1033Y according to the present seventh embodiment, a helical protrusion is not formed on the circumferential surface thereof. Furthermore, gear 33c in the above embodiments is not integrally formed with container body 1033Y, and a gear member 1042Y is rotatably installed on container body 1033Y and cap section 634Y along with agitation member 33f. Inside the container body 1033Y, different from the above embodiments, a transport member 1041Y for transporting the toner stored in the container body 1033Y towards the opening A is formed so that one end thereof is fixed to the gear 1042Y, and the the other end thereof is pivotally supported on a bearing 1033d1 of the container body 1033Y which will be described later.
[0254] The lid section 634Y has almost the same configuration as in the fifth mode except that it does not non-rotatably adhere to or is attached to the container body 1033Y.
[0255] Agitation member 33f has almost the same configuration, shape, and functions as in the above modalities except that it is not attached to container body 1033Y, but retained only in gear 1042Y.
[0256] A more detailed description will be made with reference to figures 48 and 49.
[0257] With reference to Figure 48, still in the seventh modality, on the other side of the end of the container body 1033Y in the longitudinal direction (the side opposite one side of the end, where the cap section 634Y is installed, in the longitudinal direction and an end section on the rear side in the mounting direction on the apparatus body 100), there is arranged a clamping section 1033d held by the user when the clamping/detaching operation of the toner container 1032Y is carried out. In clamping section 1033d, a hole through communicating with the interior and exterior of container body 1033Y is formed, and a cover member 1049Y that is formed of deformable flexible resin such as polypropylene or polyethylene is removably installed in the hole through. The 1049Y cover member is used when filling the interior of the 1032Y toner container (the 1033Y container body) with toner (or cleaning), for example, on the manufacturing or recycling member. Cover member 1049Y is removed from container body 1033Y when toner filling (cleaning) and mounted on container body 1033Y after toner filling is completed.
[0258] Referring to Fig. 49, the 1041Y transport member installed within the 1033Y container body is formed so that a thin flexible stirring member 1041YB formed from a material such as mylar (a trademark): a film of polyethylene) adheres to a 1041Ya shaft section, and a 1041YC agitator member is formed on the opposite side. In the shaft section 1041Ya of the transport member 1041Y, an end section on an end side in the longitudinal direction is engaged with and fixed to a connecting section 1033f20 installed at the position of the center of rotation of the stirring member 33f. An end section on the other side in the longitudinal direction is pivotally supported on the bearing section 1033d1 (which is a base section of the clamping section 1033d and formed into a section secured within the container body 1033Y). In the state that the container body 1033Y and the lid section 634Y are non-rotatably retained in the toner container storage unit 70, the stirring member 33f receives a driving force from the drive unit 91 and rotates. together with the gear member 1042Y, and thus the transport member 1041Y connected with the stirring member 33f at the position of the connecting section 1033f20 also rotates. Thus, the toner stored in a container body 1044Y is agitated by the agitating force of the agitator member 1041YC installed in the transport member 1041Y, and the toner stored in the container body 1033Y is transported towards the cap section 1034Y by the transport force of flexible stirring member 1041Yb installed on transport member 1041Y in shaft direction.
[0259] Flexible stirring member 1041Yb of transport member 1041Y includes cuts 1041Yb1 formed in a plurality of positions (in the present seventh embodiment, six positions) in the longitudinal direction. Thus, in follow-up with rotation of transport member 1041Y, the leading end of flexible stirring member 1041Yb (the free end side which is not supported on shaft section 1041Ya) comes into sliding contact with the inner circumferential surface of the container body 1033Y, and the flexible stirring member 1041Yb rotates in the suitably twisted and bent state, so that the toner stored in the container body 1033Y is stirred and transported in the right-hand direction in Fig. 49 in the axis direction.
[0260] As described above, even in the toner container 1032Y according to the present seventh embodiment, similarly to the above embodiments, toner is discharged from the toner discharge opening W of the lid section 1034Y.
[0261] In the present document, the gear member 1042Y is pivotally fixed to the container body 1033Y.
[0262] In detail, the gear engagement section (a snap-on claw section) (not shown) formed on the 1042Y gear member is caught in a flange section (wherein a boss 1033e, which will be described later, is formed) formed to loop around the outer circumferential surface of a vial mouth section 1033a of container body 1033Y, and thus gear member 1042Y is pivotally retained in container body 1033Y. In addition, a gear section (a thrust gear) is formed on the outer circumferential surface of gear member 1042Y, and when toner container 1032Y is attached to apparatus body 100, the gear section interweaves with the drive gear. 81 of the body of the apparatus 100.
[0263] A sealing material is disposed between the gear member 1042Y and the end surface of the bottle mouth section 1033a so as to prevent toner from leaking out of the toner container 1032Y. The sealing material is made of an elastic foam material such as a polyurethane foam, formed into an annular shape to be gripped within the end surface of the vial mouth section 1033a, and adheres to the gear member 1042Y. When the gear member 1042Y is fixed to the container body 1033Y, the sealing material is pressed against the opening end surface of the vial mouth section 1033a, and thus the sealing characteristic between both the members 1033Y and 1042Y is ensured .
[0264] Gear member 1042Y is not secured to cap section 1034Y, but pivotally retained in grip section 34j of cap section 634Y. A method of retaining the gear member 1042Y in the cap section 634Y is similar to the method of retaining the cap section 34Y in the vial mouth section 33a of the container body 33Y described in the above embodiments. That is, the claw section 34j of the cap section 634Y is engaged with an engaged protruding section similar to flange 1033j arranged to turn around the outer circumference of the gear member 1042Y, and the gear member 1042Y is so supported swivel on the 1034Y cover section. Through the configuration described above, container body 1033Y is connected with cap section 634Y through gear 1042Y. Furthermore, in order to prevent container body 1033Y from rotating in cap section 634Y, the mouth of vial 1033a formed near opening 1033e of container body 1033Y is fitted into a notch groove 1034t formed in the side surface of the cap section. 634Y cap to play a role of a rotation cap.
[0265] In addition, cap section 634Y, a cap seal made of an elastic foam material adheres to a section where the end surface of gear member 1042Y (the end surface on the opposite side to the side of the gear body container 1033Y) is pressed. Thus, leakage of toner from between gear member 1042Y and cap section 634Y can be prevented.
[0266] Stirring member 33f is fixed to the inner surface of gear member 1042Y. In addition, shaft section 1041Ya (the end section on an end side) of transport member 1041Y is connected to connecting section 1033f20 of stirring member 33f as described above.
[0267] As described above, still in the seventh embodiment, similarly to the above embodiments, the contact-type ID chip 535 (the information storage device) is retained in the cap section 634Y to be movable in the virtual plane which is substantially orthogonal to the direction of movement in which the 35a1, 35a2 and 35a3 metal bumpers (terminals) approach and contact the side terminals of the 573e2 body. Thus, even when the contact-type ID chip 535 (the information storage device) is installed in the 1032Y toner container (the removable device) detachably installed in the body of the imaging apparatus 100, the contact fails caused by the mismatch with the side terminals of the body 573e2 of the connector 573e of the imaging apparatus body 100 is difficult to occur.
[0268] Furthermore, in the present seventh embodiment, the lid section 634Y described, for example, with reference to figures 42A and 42B in the sixth embodiment is used as the lid section of the toner container, but as the lid section of the toner container. toner container in the present seventh embodiment, the cap section 734Y described with reference to figures 46A and 46B in the sixth embodiment can be used, the cap section 834Y described with reference to figure 47C in the sixth embodiment can be used, or the section of lid 934Y described with reference to figures 47A and 47B in the sixth embodiment can be used.
[0269] Furthermore, still in the seventh mode, similarly to the fifth and sixth modes, even when the contact-type ID 535 chip (the information storage device) is installed in the toner container (the removable device) so installed removable in the body of the imaging apparatus 100, provided that the ground terminal 535d is engaged with the side ground terminal of the body 573e25 formed on the positioning pin 573e23 (the protruding section) of the connector 573e (the body of the imaging apparatus 100 ) is formed in a 535b21 hole formed in the 535b substrate of the 535 ID chip, the 535 ID chip is difficult to be electrically damaged. EIGHTH MODE
[0270] An eighth embodiment of the present invention will be described in detail with reference to figures 50 to 51B.
[0271] Figure 50 is an exploded perspective view illustrating an image forming apparatus 1100 according to the eighth modality. Fig. 51A is a cross-sectional view illustrating part of a toner cartridge 1106Y installed in the imaging apparatus, and Fig. 51B is a bottom view illustrating part of a toner cartridge 1106Y. In figures 50 and 51B, a toner discharge mechanism and a positioning mechanism for having the toner cartridge to operate are omitted.
[0272] The imaging apparatus 1100 according to the present eighth embodiment is different from those according to the above embodiments in that the toner container 532Y, 632Y, 732Y, 832Y, 932Y or 1032Y in which the ID chip 535 is installed is mounted on the apparatus body 100 in the horizontal direction, where the longitudinal direction is the mounting direction, where the toner cartridge 1106Y on which the ID chip 535 is installed is mounted on the apparatus body 1100 from above .
[0273] Referring to Fig. 50, the imaging apparatus 1100 according to the present eighth embodiment is configured so that toner cartridges 1106Y, 1106M, 1106C and 1106K as four removable devices are attached or detached from above . Figure 50 illustrates the state in which the three toner cartridges 1106M, 1106C and 1106K except that the yellow toner cartridge 1106Y has been mounted in the body of the 1100 apparatus.
[0274] Toner cartridges 1106Y, 1106M, 1106C and 1106K are attached to or detached from an installation section of the apparatus body 100 in the state that the body cover 1110 (a body door) is opened as illustrated in the figure 50.
[0275] However, the 1106Y, 1106M, 1106C, and 1106K toner cartridges include an opening with a shutter that is disposed in the position of the underside facing the developing device and stores matching color toner (one-component developer) inside the same. With reference to figures 51A and 51B, on the lower surfaces of the end sections of toner cartridges 1106Y, 1106M, 1106C and 1106K in the longitudinal direction, the ID chip 535 (the information storage device) is movably retained by a holding member 1134K in the direction of the horizontal plane (the direction of the paper surface of figure 51B).
[0276] The 1134k retaining member is screw-coupled to the 1006Y toner cartridge to contact the 535b substrate portion of the 535 ID chip in the state where the metal buffers 35a1, 35a2 and 35a3, the positioning hole 535b21 ( the ground terminal 535d), and another of the 535 ID chip, which is the same as the one in the fifth mode, are exposed. In detail, the hole of the retaining member 1134k is combined with a bowl section 1181 formed in the end section of the toner cartridge 1106Y, a screw 1180 is screwed into a screw hole formed on the opposite side with the ID chip 535 interposed between the bowl section 1181 of the toner cartridge 1106Y and the hole formed in the retaining member 1134k, and the retaining member 1134k is secured to the toner cartridge 1106Y. Thus, the ID chip 535 does not fall out of the 1106Y toner cartridge and is retained to be movable in the horizontal plane. With reference to figure 50, following the assembly operation of the 1106Y toner cartridge from above on the 1100 body of the apparatus, the positioning pin 573e23 (the lateral ground terminal of the body 573e25) of the connector 573e installed in the section of Installation of the instrument body 1100 is fitted into the positioning hole 535b21 (the ground terminal 535d) of the ID chip 535. After this, the side terminal of the body 73e2 of the connector 573e contacts the metallic buffers 35a1, 35a2 and 35a3 of the 636 ID chip, and electrical contact between the 573e connector and the 535 ID chip is completed. In this case, since the ID chip 535 in the internal cartridge 1106Y is retained to be movable in the horizontal plane, similar to the above modalities, the contact failure caused by the positioning failure with the side terminals of the body 73e2 and 573e25 of the connector 573e 1100 apparatus body is difficult to occur.
[0277] As described above, in the present eighth embodiment, the contact-type ID chip 535 (the information storage device) is retained in the 1106Y toner cartridge to be movable in the virtual plane that is substantially orthogonal to the direction of movement in the which metal buffers 35a1, 35a2 and 35a3 (terminals) approach and contact the side terminals of the 573e2 body. Thus, even when the contact-type ID chip 535 (the information storage device) is installed in the 1106Y toner cartridge (the removable device) detachably installed in the body of the imaging apparatus 1100, the contact fails caused by the failure of positioning with the side terminals of the body 73e2 of the connector 573e of the body of the imaging apparatus 1100 is difficult to occur.
[0278] Furthermore, still in the present eighth modality, similarly to the fifth to seventh modality, even when the contact type ID 535 chip (the information storage device) is installed in the 1106Y toner cartridge (the removable device) installed detachably in the body of the imaging apparatus 1100, provided that the ground terminal 535d is engaged with the side ground terminal of the body 573e25 formed in the positioning pin 573e23 (the protruding section) of the connector 573e (the body of the imaging apparatus image 1100) is formed in a 535b21 hole formed in the 535b substrate of the 535 ID chip, the 535 ID chip is difficult to be electrically damaged. NINTH MODE
[0279] A ninth embodiment of the present invention will be described in detail with reference to figures 52 and 53.
[0280] Figure 52 is a perspective view illustrating an imaging apparatus according to the ninth modality and is a view corresponding to Figure 50 in the eighth modality. Fig. 53 is a schematic view illustrating a state where the connector 573e is connected to the ID chip 535 following a closing operation of a body cover 1210 of an apparatus body 1200.
[0281] The imaging apparatus 1200 according to the present ninth embodiment is different from those according to the eighth embodiment in that the ID chip 535 is installed on an upper surface of a 1206Y process cartridge instead of the data cartridge. toner, and connector 573e is installed in a body cover 1210 of apparatus body 1200.
[0282] Referring to Fig. 52, the imaging apparatus 1200 according to the present ninth embodiment is configured so that the process cartridges 1206Y, 1206M, 1206C and 1206K as four removable devices are attached or detached from above . Figure 52 illustrates the state in which the three process cartridges 1206M, 1206C, and 1206K except that the yellow process cartridge 1206Y has been mounted in the body of the 1200 apparatus.
[0283] Process cartridges 1206Y, 1206M, 1206C and 1206K are attached to or detached from an installation section of apparatus body 1200 in the state that body cover 1210 (the body door) is opened as illustrated in the figure 52. In the present document, in the present ninth modality, on the 1210 body cover, LED units 1207Y, 1207M, 1207C and 1207K to carry out an exposure process are installed in the positions corresponding to the four process cartridges 1206Y, 1206M, 1206C and 1206K , respectively (in figure 52, the two LED units 1207Y and 1207M are omitted). Referring to Fig. 53, when the body cover 1210 is closed, the LED unit 1207Y moves to face the positioning of the photosensitive drum 1201Y for an electrostatic latent image on the 1206Y process cartridge.
[0284] However, in each of the 1206Y, 1206M, 1206C, and 1206K process cartridges, the photosensitive drum, charging unit, developer unit, and cleaning unit are integrally formed, and the corresponding color toner (one developer) is stored inside the developer unit. Referring to Figure 52, on the upper surfaces of the end sections of the 1206Y, 1206M, 1206C and 1206K process cartridges in the longitudinal direction, the ID chip 535 (the information storage device) is retained by the retaining member (not shown ) (or the face plate) to be movable in the horizontal plane direction (the vertical direction and the left to right direction in the paper plane of figure 53).
[0285] The retaining member is screw-coupled to an outer cover of the 1206Y process cartridge to contact part of the 535b substrate of the ID chip 535 in the state where the metal buffers 35a1, 35a2 and 35a3, the hole of positioning 535b21 (the ground terminal 535d) and the other of the ID chip 535 which is shaped similarly to the fifth mode are exposed. Thus, the ID chip 535 does not fall out of the 1206Y cartridge process and is retained to be movable in the horizontal plane. With reference to figure 52, in accompaniment with the assembly operation of the 1206Y process cartridge from above in the apparatus body 1200 o (the assembly operation in accompaniment with the closing operation of the body cover 1210), the pin of positioning 573e23 (the 573e25 body side ground terminal) of the 573e connector installed in the 1210 body cover is fitted into the 535b21 positioning hole (the 535d ground terminal) of the ID chip 535. Therefore, the 73e2 body side terminal of the connector 573e contacts the 35a1, 35a2 and 35a3 metal buffers of the 535 ID chip, and electrical contact between the 573e connector and the 535 ID chip is completed. In this case, since the 535 ID chip in the 1206Y process cartridge is retained to be movable in the horizontal plane, similarly to the above modalities, the contact failure caused by the positioning failure with the 573e2 and 573e25 body side terminals of the 573e connector of the 1200 device body is difficult to occur.
[0286] Furthermore, in the present ninth embodiment, with reference to figure 53, the LED unit 1207Y (having an end section in which the connector 573e is installed) is installed to be swivel (oscillating) on the body cover 1210 clockwise or counterclockwise in figure 53 through a 1211 support arm. The 1207Y LED unit is stimulated by a compression spring 1212 installed inside the 1211 support arm. When the 1210 body cover is closed to mount the four LED units on the process cartridges by the wobble function and the stimulus force against the side of the process cartridges, as illustrated in figure 53, the 1207Y LED unit shakes the neck along the wall surface of the 1206Y process cartridge and is oriented in a predetermined direction. At the same time, the 573e connector also moves to address the 535 ID chip and is positioned similarly to the fifth through eighth modes. Thus, due to the stimulating force of compression spring 1212, connector 573e contacts the ID chip 535 of process cartridge 1206Y mounted in the installation section of apparatus body 1200 with the appropriate force.
[0287] As described above, in the present fifth embodiment, the contact-type ID chip 535 (the information storage device) is retained in the process cartridge 1206Y to be movable in the virtual plane that is substantially orthogonal to the direction of movement in that the 35a1, 35a2 and 35a3 metal bumpers (terminals) approach and contact the side terminals of the 573e2 body. Thus, even when the contact-type ID chip 535 (the information storage device) is installed in the 1206Y process cartridge (the removable device) detachably installed in the body of the imaging apparatus 1200, the contact fails caused by positioning failure with the side terminals of the body 573e2 of the connector 573e of the imaging apparatus body 1200 is difficult to occur.
[0288] Furthermore, in the present ninth embodiment, even when the contact-type ID chip 535 (the information storage device) is installed in the process cartridge 1206Y (the removable device) detachably installed in the body of the device. imaging 1200, provided that the ground terminal 535d engages with the side ground terminal of the body 573e25 formed on the positioning pin 573e23 (the protruding section) of the connector 573e (the body of the imaging apparatus 1200) is formed in a hole 535b21 formed on the 535b substrate of the 535 ID chip, the 535 ID chip is difficult to be electrically damaged. TENTH MODE
[0289] A tenth embodiment of the present invention will be described in detail with reference to figures 54 and 55.
[0290] Figure 54 is a perspective view illustrating an ink cartridge 1306Y (a developer container) according to the tenth embodiment. Figure 55 is a front view illustrating an ink jet printer 1300 as an imaging apparatus in which ink cartridges 1306Y, 1306M, 1306C and 1306K are installed.
[0291] The imaging apparatus 1300 according to the present tenth embodiment is different from those according to the above embodiments in that the ink cartridge 1306Y having the side surface on which the ID chip 535 is installed is mounted in the body of the apparatus 1300 from the side.
[0292] Referring to Fig. 55, the image forming apparatus 1300 (the ink jet printer) according to the present tenth embodiment includes a carriage 1301 which includes the recording heads 1301a and 1301b and moves in a direction of a double-headed arrow, an orientation latch 1302, a supply tube 1303 supplying ink from ink cartridges 1306Y, 1306M, 1306C and 1306K of respective colors to a carriage subtank 1031, a conveyor belt 1304 for carry a recording medium F in one direction of an arrow, and the like. The 1306Y, 1306M, 1306C and 1306K ink cartridges of the respective colors (the removable devices) are detachably installed in an installation section arranged in the end section of the 1300 apparatus body (installation having the vertical direction in figure 55 as the attachment/detachment direction).
[0293] In addition, a main configuration of an imaging apparatus 300 is the same as depicted, for example, in JP Patent Application Open to the Public No. 2010-234801 and is well known, and thus a detailed description of the same will not be repeated.
[0294] Referring to Fig. 54, in ink cartridge 1306Y (an ink pouch 1307 is stored therein) as the removable device, the ID chip 535 (the information storage device) retained in a member of 1334k retainer to be movable in the XZ direction is installed in a concave section 1308 formed on the side surface thereof.
[0295] The 1334k holding member and the 535 ID chip have the same configuration similar to those of the fifth mode. That is, the retaining member 1334k is fitted within the concave section 1308 of the ink cartridge 1306Y in the state where the metallic buffers 35a1, 35a2 and 35a3, the positioning holes 535b21 (the ground terminal 535d) and the other of the chip ID 535 are exposed. Thus, the ID chip 535 does not fall out of the ink cartridge 1306 Y and is retained in the retaining member 1334k to be movable in plane XZ. With reference to Figure 54, following the assembly operation in the 1300 apparatus body, the positioning pin 573e23 (the side ground terminal of the 573e25 body) of the 573e connector installed in the 1300 apparatus body is fitted into the positioning hole 535b21 (the 535d ground terminal) of the ID chip 535. After that, the side terminal of the body 73e2 of the connector 573e comes in contact with the metal buffers 35a1, 35a2 and 35a3 of the ID chip 535, and the electrical contact between the connector 573e and the 535 ID chip is completed. In this case, since the 535 ID chip in the 1306Y ink cartridge is retained to be movable in the XZ plane, similarly to the above modalities, the contact failure caused by the positioning failure with the body side terminals 573e2 and 573e25 of the connector 573e of the body of the 1300 apparatus is difficult to occur.
[0296] As described above, in the present tenth embodiment, the contact-type ID chip 535 (the information storage device) is retained in the ink cartridge 1306Y via the retaining member 1334k to be movable in the virtual plane which is substantially orthogonal to the direction of motion in which the 35a1, 35a2 and 35a3 metal buffers (terminals) approach and contact the side terminals of the 573e2 body. Thus, even when the contact-type ID chip 535 (the information storage device) is installed in the 1306Y ink cartridge (the removable device) detachably installed on the body of the imaging apparatus 1300, the failure of contact caused by misplacement with the side terminals of the body 573e2 of the connector 573e of the body of the imaging apparatus 1300 is difficult to occur.
[0297] Furthermore, still in the present tenth modality, even when the contact-type ID 535 chip (the information storage device) is installed in the 1306Y ink cartridge (the removable device) removablely installed in the body of the apparatus of imaging apparatus 1300, provided that the ground terminal 535d engaged with the side ground terminal of the body 573e25 formed on the positioning pin 573e23 (the protruding section) of the connector 573e (the body of the imaging apparatus 1300) is formed in a 535b21 hole formed in the 535b substrate of the 535 ID chip, the 535 ID chip is difficult to be electrically damaged. ELEVENTH MODE
[0298] An eleventh embodiment of the present invention will be described in detail with reference to figures 56 to 58.
[0299] Figure 56 is a perspective view illustrating a connector 1473e of an imaging apparatus according to the tenth embodiment and is a view corresponding to Figure 16 according to the first embodiment. Fig. 57 is a three plan view illustrating an ID chip 1435 as an information storage device that contacts the connector 1473e of Fig. 16 and is a view corresponding to Fig. 29 according to the first embodiment. Fig. 58 is a three plan view illustrating an ID chip 1535 as an information storage device otherwise and is a view corresponding to Fig. 35 according to the fourth embodiment.
[0300] The eleventh embodiment is different from the first and fourth embodiments in that the side ground terminal of the 1473e5 body is installed on a positioning pin 1473e3 of the 1473e connector, and a metallic ground terminal 1435d or 1535d (a ground terminal) that enters in contact with the side ground terminal of the 1473eb body is installed on the 1435 or 1535 ID chip.
[0301] Referring to Figure 56, in the imaging apparatus according to the present eleventh embodiment, similarly to the first embodiment, the connector 1473e is installed which includes a connector body 1473e1, four lateral terminals of the body 1473e2, two 1473e3 positioning pins (protruding positioning sections), a 1473e4 quick fit, and the like.
[0302] In connector 1473e according to the present eleventh embodiment, the side terminal of the body 1473e5 (the ground terminal) is installed within the positioning pin 1473e3 (a section that contacts a notch 1435b1 of the ID chip 1435 or an orifice 1535b11).
[0303] However, with reference to Fig. 57, on the ID chip 1435 (the substrate 1435b) according to the present eleventh embodiment, the metallic ground terminal 1435d (the ground terminal) is installed on the inner surface of the two notches 1435b1 and around the two notches 1435b1).
[0304] Through the configuration described above, in the toner container assembly operation, the 1435d ground terminal of the 1435 ID chip contacts the 1473e5 body side terminal (for example, see figure 56) of the 1473e3 positioning pin (the 1473e connector), and then the fourth metallic snubber 35a of the 1435 ID chip begins to contact the four side terminals of the 1473e2 body of the 1473e connector. That is, in the operation of detaching the toner container, the contact between the four metallic buffers 1435 and the four side terminals of the 1473e2 body of the 1473e connector is released, and then the ground terminal 1435d of the 1435 ID chip is released from the state of contact with (separated from) the 1473e5 body side ground terminal of the 1473e3 positioning pin (the 1473e connector). Specifically, the 1473e5 body side ground terminal at the 1473e connector has the closest contact start position to the 1435 ID chip than the four 1473e2 body side terminals.
[0305] Through the configuration described above, in the toner container assembly operation, PS metallic buffers 35a always start to be connected with the side terminals of the 1473e2 body in the state where the 1435 ID chip is grounded, and in the operation of detachment from the toner container, the metallic buffers 35a always begin to separate (released from the state of contact with) from the side terminals of the 1473e2 body in the state where the 1435 ID chip is grounded. Thus, an electrical circuit in the 1435 ID chip is prevented from being grounded and thus becomes an electrically floating state, and thus the 1435 ID chip is difficult to be electrically damaged.
[0306] Furthermore, similarly to a relationship between the ID chip according to the first modality and the ID chip according to the fourth modality, the ID chip 1435 illustrated in Fig. 57 can be replaced with the ID chip 1535 illustrated in Figure 58.
[0307] In detail, with reference to Fig. 58, on the ID chip 1535, a metallic ground terminal 1535d (a ground terminal) is installed on the inner surface of a positioning hole 1535b11 and around the positioning hole 1535b11.
[0308] Through the configuration described above, in the operation of assembling the toner container, the ground terminal 1535d of the ID chip 1535 contacts the side ground terminal of the body 1473e5 (for example, see figure 56) of the positioning pin 1473e3 (the 1473e connector), and then the metal bumper frames 35a of the 1535 ID chip begin to contact the four side terminals of the 1473e2 body of the 1473e connector. That is, in the toner container detachment operation, the contact between the four metallic buffers 35a of the ID chip 1535 and the four side terminals of the body 1473e2 of the connector 1473e is released, and then the ground terminal 1535d of the ID chip 1535 is released from the state of contact with (separated from) the side ground terminal of the 1473e5 body of the 1473e3 positioning pin (the 1473e connector). Specifically, the 1473e5 body side ground terminal at the 1473e connector has the closest contact start position to the side of the ID chip 1535 than the four 1473e2 body side terminals.
[0309] Through the configuration described above, in the toner container assembly operation, the metallic buffers 35a always start to be connected with the side terminals of the 1473e2 body in the state where the 1535 ID chip is grounded, and in the operation of detachment from the toner container, the metal buffers 35a always begin to separate from (released from the state of contact with) the side terminals of the body 1473e2 in the state where the ID chip 1535 is grounded. Thus, the electrical circuit in the 1535 ID chip is prevented from being grounded and thus becomes an electrically floating state, and thus the 1535 ID chip is difficult to be electrically damaged.
[0310] As described above, still in the eleventh embodiment, the contact-type ID chip 1435 or 1515 (the information storage device) is retained in the holding member 34k (the holding section) to be movable in the virtual plane which is substantially orthogonal to the direction of motion in which the metallic bumpers 35a (terminals) approach and contact the side terminals of the body 1473e2.
[0311] Thus, even when the contact-type ID chip 1435 or 1535 (the information storage device) is installed in the toner container (the removable device) detachably installed in the body of the imaging apparatus, the contact failure caused by misplacement with the side terminals of the body 1473e2 of the connector 1473e of the imaging apparatus body is difficult to occur.
[0312] As described above, in the present eleventh embodiment, even when the contact-type 1435 or 1535 ID chip (the information storage device) is installed in the toner container (the removable device) detachably installed in the body of the imaging apparatus 100, provided that the ground terminal 1435d or 1535d is engaged with the side ground terminal of the body 1473e5 formed on the positioning pin 1473e3 (the protruding section) of the connector 1473e (the body of the imaging apparatus 100) whether formed in the 1435b1 notch or the 1535b11 hole formed in the 1435b or 1535b substrate of the 1435 or 1535 ID chip, the 1435 or 1515 ID chip is difficult to be electrically damaged. TWELFTH MODE
[0313] A twelfth embodiment of the present invention will be described in detail with reference to figures 59 to 62.
[0314] Figure 59 is a perspective view illustrating a 1632Y toner container as a removable device according to the twelfth embodiment. Toner container 1632Y includes a container body 1633Y having the same configuration as container body 33Y, a cap section 1634Y covering a toner discharge opening (not shown) formed in container body 1633Y from the outside. , an ID chip as an information storage device attached to the leading end of the cap section 1634Y, and a retention mechanism 1635 that retains the ID chip. For example, the 535 ID chip described in the fifth embodiment can be used as the ID chip.
[0315] Toner container 1632Y refers to a toner container attachable to and detachable from a toner feeding device of a toner suction conveyor type disclosed in JP Patent No. 4396946 or US Patent No. 7,835,675. That is, except for the ID chip, the retention mechanism, and an ID chip communication method, the toner container and toner feeding device disclosed in the relevant patent are employed. The relevant patent is referred to in connection with a positioning configuration allowing to fix and detach, arranged in both the toner container and the feeding device, a configuration for actuating the container body, and the like. The difference between the toner container of the present embodiment and the toner container of JP Patent No. 4396946 or US Patent No. 7,835,675 will be described later. The toner feeding device of the present embodiment is different from the toner feeding device of JP Patent No. 4396946 or US Patent No. 7,835,675 in that the former employs a contact type communication method, while the latter employs a communication method non-contact (a so-called RFID method). Thus, the side connector of the body of the first, connector 573e of Figures 37, 38 and 45 described with reference to the fifth embodiment is disposed in a position facing the end surface of the cover of the toner container of the toner feeding device of the JP Patent No. 4396946 or US Patent No. 7,835,675.
[0316] As illustrated in Figure 60, the positioning hole 535b21 described above is formed in the ID chip 535, and, for example, the positioning pin 573e23 of the connector installed in the apparatus body described above is inserted into the positioning hole 535b21 .
[0317] The 1635 retainer mechanism includes a 1635A retainer section which retains the 535 ID chip in a movable form in the XZ direction and a 1635B retainer cap as a cap member that is releasably fitted within the retainer section 1635A.
[0318] As illustrated in Figure 61, the 1635A retaining section includes a 1635Aa concave section formed on a 1634Ye ID chip mounting surface that is vertically flat and formed on the leading end of the 1634Y cap section, a 1635q pedestal section , formed in the concave section 1635Aa, in which the ID chip 535 is installed, and an ID chip mounting wall section 1635Ab of a substantially frame shape formed to surround the concave section 1635Aa and the pedestal section 1635q from on the outside. The 1635Ab ID chip mounting wall section is shaped to protrude away from the 1634Yi ID chip mounting surface farther than the 1635g pedestal section. The 1635Ab ID chip mounting wall section is sized capable of storing the 535 ID chip having an external rectangular shape and retains the 535 ID chip in a moving mode in the XZ direction when the 535 ID chip is placed. That is, the 535 ID chip is installed in the 1635q pedestal section, but not attached to the 1634Y cover section. When installed in the 1635q pedestal section, the 535 ID chip is installed with clearance with the 1635Ab ID chip mounting wall section that is formed to surround the 535 ID chip from the outside.
[0319] On the 1634Ya mounting surfaces of the ID chip, the positioning cups 1615a and 1615b for mounting the 1635B retaining cover are formed to protrude from the 1634Ya mounting surface of the ID chip. Positioning cups 1615a and 1615b are integrally formed with cap section 1634Y by resin.
[0320] Retainer cover 1635B is mounted and secured to retainer section 1635A by a fusion clamping method (eg, thermal caulking), described below, with the ID chip being disposed on retainer section 1635A. A center section of the 1635B retaining cover is provided with an opening 1635Bc that allows a contact point (not shown) and the 535b21 positioning hole of the 535 ID chip to be exposed to the outside and allows the connector terminal (not shown) of the connector and the positioning pin 573e23 are inserted through. The 1635B retaining cover is configured to sandwich the 535 ID chip fixed inside the 1635Ab ID chip mount wall section together with the 1635Ab ID chip mount wall section so that the 535 ID chip does not separates. Above and below opening 1635Bc of retaining cap 1635B, mounting holes 1635Ba and 1635Bb are formed at positions corresponding to positioning cups 1615a and 1615b.
[0321] In this configuration, when mounting the 535 ID chip on the 1634Y cover section, the back surface of the 535 ID chip contacts the 1635q pedestal section so that its position in a depth direction is determined. Throughout this, placement above, below, left and right is done in a surrounding manner thanks to the 1635Ab wall section of ID chip installation. The 1635B retaining cover is superimposed on the ID chip mounting wall section 1635Ab in a direction facing the ID chip mounting wall section 1635Ab, and the positioning cups 1615a and 1615b are inserted into the mounting holes 1635Ba and 1635Bb . Thus, the ID chip 535 is positioned in a covered state by the 1635B retaining cap, and mounted and retained in the 1634Y cap section. In this state, the 535 ID chip is installed on the 1634Ya ID chip mounting surface of the 1634Y cover section, but it is not directly attached to the 1634Y cover section. That is, the 535 ID chip is mounted on the 1634Y cover section through the 1635Ab ID chip mounting wall section formed on the 1634Ya mounting surface of the ID chip.
[0322] The present modality presents a method of fixing between the retaining cover 1635B and the cover section 1635Y. In the present embodiment, a melt-attachment method is employed as a method of attaching the retaining cap 1635B and cap section 1634Y.
[0323] Since the retaining cap 1635B is retained so that the positioning cups 1615a and 1615b formed in the cap section 1634Y are inserted into the mounting holes 1635Ba and 1635Bb as described above, in the present embodiment, as illustrated in figure 62 , retaining cover 1635B is secured to cover section 1634Y by thermal caulking. In Fig. 62, a reference numeral 1640 represents a caulking section (a fastening section). For example, the positioning bulges 1615a and 1615b illustrated in Fig. 61 are sized protruding from mounting holes 1635a and 1635b. The positioning cups 1615a and 1615b are heated by a heating member such as a heatable iron, and the caulking section 1640 is formed by crushing and thermally deforming the cups while melting them with heat. Consequently, retaining cap 1635B can be secured and secured to cap section 1634Y.
[0324] In the present embodiment, as the method of attachment between the retaining cap 1635B and the cap section 1634Y, the thermal caulking attachment is described, but as the method of attachment between the retaining cap 1635B and the cap section 1634Y, another fusion fixing method such as ultrasonic welding can be used, and a resin fusion method not limited to the present embodiment. THIRTEENTH MODE
[0325] A thirteenth modality will be described in detail with reference to figures 63 and 64.
[0326] In the present embodiment, the retaining cover 1635B is not fixed by a process such as thermal caulking, but fixed by a fastening method using a fastening member. The remaining sections of toner container and the shape of the toner feeding device are the same as in the twelfth modality. In the present embodiment, retaining cap 1635B is affixed to cap section 1634Y such that locking members 1650a and 1650b are inserted into mounting holes 1635Ba and 1635Bb formed in retaining cap 1635B which allow for positioning bulges 1615a and 1615b are inserted into and screwed into the 1634Ya mounting surface of the ID chip. For example, when screw fastening is performed using a self-tightening that creates a screw slot in an opposite hole at the same time when it is screwed into the opposite hole as fastener members 1650a and 1650b, all you have to do is to form a tubular pilot hole (corresponding to 1615a and 1615b of figure 64) in the 1634Ye mounting surface of the ID chip.
[0327] As another embodiment, for example, there is a case where the retention cover 1635B is attached to the cover 1634Y without the ID chip being retained therein and then the resulting product is shipped from a toner container manufacturing plant , and then in another factory, the 1635B retaining cap is removed, the ID chip is affixed to the inside, and the 1635B retaining cap is fixed to the 1634Y cap, or there is a case to recycle the waste toner container. In this case, if the attachment/detachment of the retaining cap 1635B is repeated over a certain range, the tubular pilot hole described above is preferable. However, if five or six times or more times of fixations/detachments are expected and the stability of the clamping force on each occasion can be considered, it is preferable that the screw holes 1615a and 1615b be formed in advance in the mounting surface 1634Ya of the ID chip, and fastening is effected by screwing the screws into screw holes 1615a and 1615b through mounting holes 1635Ba and 1635Bb so as to match the spacing of screw holes 1651a and 1651b as fastening members 1650a and 1650b, as illustrated in Fig. 64. In the present embodiment, the clamping members 1650a and 1650b are secured in two positions below and above the retaining cap 1635B, but can be secured in one or more positions, then above. In addition, fastening members 1650a and 1650b can be mounted on the left and right sides rather than the top and bottom sides of retaining cap 1635B, and are not limited in number and position to the present embodiment. FOURTEENTH MODE
[0328] A fourteenth embodiment of the present invention will be described in detail with reference to figures 65 and 66.
[0329] In the present embodiment, the retaining cover is characterized in that it is not secured to and secured to the cover section 1634Y by a process such as thermal caulking or the fastening member, but secured by an adjustment method using a fitting member. claw. The remaining sections of the toner container and the shape of the toner feeding device are the same as in the twelfth modality.
[0330] A holding cover 1635C according to the present embodiment has basically the same function as the holding cover 1635B. Specifically, mounting holes 1635Ba and 1635Bb are eliminated from the retaining cap 1635B, and instead hook sections 1636a and 1636b that pass through to an opening 1635Cc formed in a center section are formed in an upper section 1635Ca and a lower section 1635Cb. Similar to 1635Bc aperture. The 1635Cc opening allows the contact point (not shown) and the 535B21 positioning hole of the 535 ID chip to be exposed to the outside and allows the connector terminal (not shown) of the connector and the 573e23 positioning pin to pass through the same.
[0331] In the present embodiment, the cover section 1634Y, as illustrated in figure 66, is provided with the claw sections 1637a and 1637b as engagement sections that enter the interior of the hook sections 1636a and 1636b and engage with the sections of hook 1636a and 1636b. In the present embodiment, claw sections 1637a and 1637b are formed to be disposed respectively in the upper section and the lower section of the ID chip mount wall section 1635Ab covered with the retaining cover 1635C. Clamp sections 1637a and 1637b have sloping surfaces 1637a1 and 1637b1 formed on the insertion side and are configured so as to orient retainer cap 1635C to the tops of clamp sections 1637a and when retainer cap 1635C is aligned and mounted.
[0332] With this configuration, when the 535 ID chip is fixed to the 1635Ab ID chip mount wall section and the 1635c retaining cover is moved towards the 1635Ab ID chip mount wall section so that it overlaps on the ID chip mount wall section 1635Ab, the claw section 1637a formed on the ID chip mount wall section 1635Ab which becomes the side of the cover section 1634Y enters the interior of the hook sections 1636a and 1636b formed on the cover retaining cap 1635C, and retaining cap 1635C can be attached to cap section 1634Y by fitting between both sides.
[0333] In the present embodiment, the hook sections 1636a and 1636b are fitted within the grip sections 1637a and 1637b in the two positions of the upper and lower sections of the 1635C retaining cap, but they can be fitted in the left and right sections or in the top, bottom, left, and right sections of the 1635C Retention Cover instead of the top and bottom sections. The adjustment position and number are not limited to the present mode.
[0334] In the thirteenth and fourteenth embodiments, the method of attaching or adjusting the retaining cap 1635C to be attached to or detached from the cap section 1634Y is described. However, as another method of attachment, for example, the cover member can be attached to the ID chip mounting wall section 1635Ab by an adhesive. In this case, the cover member preferably has sufficient adhesive strength not to fall out upon detachment of the toner container 1632Y from the body of the apparatus, and a type of an adhesive and an adhesion area is not particularly limited.
[0335] In the twelfth to fourteenth modes, even in any mode, even when the 535 ID chip which is the contact type information storage device is installed in the 1632Y toner container, the contact failure caused by poor positioning relative to the connector terminal of the device body is difficult to occur. FIFTEENTH MODE
[0336] In the toner container according to any of the fifth to seventh embodiments, part of the invention (the shutter mechanism) for solving the third problem described above will be described in detail again as a fifteenth embodiment.
[0337] The buffer release stimulus section 72b in figure 5 will be described with reference to figure 18 and subsequent figures. The cap release stimulus section 72b is a section used to open the toner discharge opening W by moving the shutter 34d disposed in the cap section 34Y from the closed state to the open state in conjunction with the insertion operation (assembly ) of the 32Y, 32M, 32C and 32K developer storage container. The plug release stimulus section 72b is configured with a trapezoidal rib that protrudes upward from the upper surface of the vial receiving surface 72a towards the obturator.
[0338] However, figures 18 and 20 illustrate the total configuration of the 32Y, 32M, 32C and 32K developer storage containers (see figure 18) and the details of the lid section 34Y disposed on the container (see figure 20).
[0339] In Figure 18, the developer storage container 32Y mainly includes the container body 33Y (the bottle body) and the cap section 34Y (the bottle cap) disposed on the head of the same. Furthermore, the ID chip 35 as the removable device or the like is detachably installed on the lid section 34Y of the developer storage container 32Y.
[0340] Among the sections described above, the configuration illustrated in figure 20 is used in the position where the ID chip 35 is installed so that the ID chip 35 can be mounted.
[0341] On the surface of the leading end of the cap section 34Y. as illustrated in Figure 20, the first and second positioning holes 34a and 34b which can be engaged with the first and second positioning pins (not shown) arranged in the cap receiving section 73 are arranged in two positions in the longitudinal direction (a vertical direction).
[0342] Between the first and second positioning holes 34a and 34b, a rectangular concave section 34t is formed which has a shape connectable with the connector disposed in the developer storage container storage unit 70 (see figure 5) and extends in the vertical direction as illustrated in figures 67 and 68. Within the concave section as illustrated in figure 67, the retaining member 34k to which the ID chip is attachable is mounted. A reference numeral 33f illustrated in Fig. 67 represents the stirring member having a stirring section positioned within the cap, and the stirring member rotates in conjunction with gear 33c which will be described later.
[0343] The mounting position of the retaining member 34k is vertically higher than the position of the toner discharge opening W which is opened or closed by the shutter 34d which will be described later with reference to figures 70A to 70C (in figure 67 , for convenience, the position having the height H between the bottom section 34t1 of the concave section 34t and the toner discharge opening W), and thus the retaining member 34k is separated from the toner discharge opening W. a convex wall is disposed on a circumferential edge of the rectangular concave section. Thus, the state is obtained that part of the concave section 34t is difficult to be superimposed on the part of the toner discharge opening W in the transverse direction. That is, the bottom section 34t1 of the concave section 34t does not come close to the toner discharge opening W. Thus, part of the toner discharge opening W is prevented from being filled with the bottom section 34t1, and the toner discharge is not inhibited. Furthermore, even when toner leaks and is scattered from the toner discharge opening W of the 32Y developer storage container to the outside, the scattered toner does not reach the connector against its own weight, and the scattered toner is blocked by the convex wall. Thus, contact failure caused when toner adheres to the connector can be prevented, and the occurrence of communication failure can be prevented. The concave section 34t is disposed alongside the first positioning hole 34a.
[0344] However, in the head section of the container body 33Y illustrated in figure 20, as illustrated in figure 67, the gear 33c integrally rotating together with the container body 33Y and the opening A are disposed on an end side in the direction longitudinal (the direction from left to right in figure 67).
[0345] The opening A is arranged in the head section positioned on the front side when the container body 33Y is assembled and allows the toner stored in the container body 33Y to be discharged towards a hollow space section B within the section of 34Y cover.
[0346] Furthermore, as the toner is consumed on the body side of the imaging apparatus, the toner transport (drive with rotation of the container body 33Y) from the inside of the container body 33Y to the hollow space B inside the 34Y cap section is done properly.
[0347] Next, the configuration of the lid section 34Y of the developer storage container 32Y will be described below with reference to figures 20, 67 and 68.
[0348] In the lid section 34Y of the developer storage container 32Y, the ID chip 35 (the information storage device), the shutter member 34d and the shutter seal 36 are installed.
[0349] As illustrated in figure 68, the cap section 34Y has a structure in which a roughly cylindrical body in which the outer diameter and the outer diameter decrease from the side of the container body 33Y towards the side of the shutter member 34d in three stages (large, medium and small) is combined with a box section, arranged at the bottom, where the width in the horizontal direction decreases in two stages (wide width and narrow width). The cap section 34Y includes an insert section including the large diameter section and the medium diameter cylindrical section and the wide width box section 34n.
[0350] In the large diameter section of the cap section 34Y, a cut hole 34P0 formed so that part of the outer circumference is removed is disposed, and as illustrated in figure 68, part of the gear teeth 33c is exposed to the outside .
[0351] In the insert section, in figure 68, a circumferential section 34P1 adjacent to the cut hole 34P0 in the axis direction has the outer diameter smaller than a circumferential section 34P2 that is not adjacent to the cut hole 34P0 in the circumferential direction. In Fig. 68, for convenience, D1 and D2 representing the outside diameters are attached to the reference numbers of the circumferential sections 34P1 and 34P2, and the ratio between the outside diameters is D1<D2.
[0352] As described above, the circumferential section adjacent to the hole of cut 34P0 of the insertion section in the direction of the shaft has the outer diameter smaller than the other sections, and thus, the surface of the gear teeth engaged with the gear 33c, which is exposed on the outside through the cut hole 34P0, in the axis direction it becomes difficult to interfere with the outer circumference of the insert section. As a result, the engagement operation of gear 32c with the gear moving in the shaft direction can be carried out smoothly without being disturbed by the insertion section.
[0353] Furthermore, in Fig. 68 and Fig. 81 illustrating a seventeenth embodiment, which will be described later, which is a modification in which a main part is shared with the configuration illustrated in Fig. 68, a reference number 34YG0 represents a retaining section configured by a step section on the leading end side of a 34YG guide rail. The retaining section 34YG0 is a section that is reached by a sliding protruding section 34d1c (see figures 70A to 70C) disposed to the side of the shutter 34d so that the shutter 34d cannot move any further, thus retaining the shutter 34d as will be described later.
[0354] As described in detail in Fig. 81, an upper rail rib 34SG which is at a predetermined distance from the guide rail 34YG and parallel to the guide rail 34YG is disposed above the guide rail 34YG. The upper rail rib 34SG prevents an interleaving section of a body side shutter closure mechanism 73d (see figure 72) illustrated in figure 72 and subsequent drawings thereof from penetrating between the circumferential cylindrical surface of the lid 34Y and the rail 34YG guide.
[0355] On the upper surface of guide rail 34YG, a projecting section of plug 34YG2 including a projecting section is disposed in the position that plug 34d reaches before reaching the retaining section 34YG0 (see figure 81). The projecting section of shutter 34YG2 is used as a section to restrict shutter movement 34d when shutter 34d is in the closed state.
[0356] An insertion/removal (attachment/detachment) operation of the developer storage container 33Y can be performed by the user by squeezing the clamping section arranged on the rear side end section of the container body 33Y in the insertion (mounting) direction as indicated by a reference numeral 33d in figure 18.
[0357] A narrow width box section 34Y1 is formed in the small diameter cylindrical section of the cap section 34Y, and inside the box section 34Y1, as illustrated in figure 69B, the toner discharge opening W for discharging ( falling by its own weight) the toner from the opening A of the container body 33Y, to the underside in the vertical direction, i.e. into the container is arranged to communicate with the hollow space section B illustrated in the figure 67.
[0358] As illustrated in Figure 69B, the toner discharge opening W is formed in a hexagonal shape which is one of the polygonal shapes and has a predetermined flow passage area and communicates the lower lateral circumferential surface of the space B within the Small diameter cylindrical section with toner discharge opening W (discharge opening). Thus, the discharged toner into the space B inside the small diameter cylindrical section of the cap section 34Y from the opening A of the container body 33Y falls from the hexagonal cylindrical shaped toner discharge opening W by its own weight and then is gently discharged to the outside of the container (the 61Y toner tank section).
[0359] In the toner discharge opening W, as illustrated in figures 67 and 69B, a rib W1 protruding towards a sealing material 36 of the shutter 34d that will be described later is formed along the circumferential edge of the opening. The rib W1 has a function of bending and suspending the end section of the sealing material 36 which will be described later, a function of improving the adhesion of the sealing material 36 coming into pressing contact with a section other than the end section, and a function to catch toner that is about to leak out of the toner discharge opening W.
[0360] In figures 69A and 69B, in the bottom section of the narrow-width box section 34Y1 arranged in the lower section of the cover section 34Y, the shutter 34d for effecting the opening and closing of the toner discharge opening W together with the attachment/detachment operation of the developer storage container 32Y in the developer storage container storage unit 70 is retained to be slidably movable.
[0361] The shutter 34d is a characteristic section of the present invention and has the following configuration that will be described with reference to figures 70A and 70B. Furthermore, Fig. 70A is a perspective view where the shutter 34d is viewed from the bottom surface side, and Fig. 70B is a perspective view where the shutter 34d is viewed from the top surface.
[0362] The plug 34d is made of a resin material such as polystyrene and mainly includes a plate-like main plug section 34d1 and a plug deformation section 34d2 which stresses the main plug section 34d1, which is thinner in thickness than the main shutter section 34d1, and has elasticity.
[0363] In shutter section 34d1, the vertical wall 34d1a remaining in both side end sections of a plate section and a pair of shutter sliders 34d12 having objects protruding from the vertical walls is disposed.
[0364] The vertical walls 34d1a include a pair of sliding raised sections 34d1c that are arranged on the inner side surfaces of the vertical walls to protrude toward each other and L-shaped engaged raised sections 34d1b that are disposed on the outer side surfaces in the side opposite the sliding protruding sections 34d1c.
[0365] The engaged protrusion section 34d1b is shaped so that a plate section extending in the shutter movement direction is present on the upper surface, and a protrusion 34d1b1 engaged with an interleaving section which will be described later extends upwards from a section positioned on the front side of the plate section in a developer storage container insertion direction.
[0366] The shutter slider 34d12 includes a pair of prismatic sections that are arranged to protrude from the surface on the same side as the engaged protruding section 34d1b of the vertical wall 34d1a and extends to the rear side in the closing direction of the Toner discharge aperture W of shutter 34d indicated by an arrow.
[0367] In the present embodiment, as illustrated in Figure 70B, the protrusion 34d1b1 arranged in the engaged protruding section 34d1b is arranged in the offset position of the front end surface of the main shutter section 34d1 (the position where a section corresponding to a distance indicated by an S1 symbol in figure 70B is removed). As will be described in Fig. 72 and subsequent drawings, the boss 34d1b1 is used as a section to prevent interference when one of the interleaving sections 73d2 (see Fig. 72) disposed in a body side plug closure mechanism 73d begins to turn.
[0368] In shutter 34d, shutter deformation section 34d2 is configured in a cantilever shape, and an inner side angled section of a base station connected to main shutter section 34d1 is formed in a curvature-shaped section similar to arc (a shape indicated by the symbol R in figures 70A and 70B) and functions to prevent stress concentration when deformed with deviation.
[0369] In addition, the shutter deformation section 34d2 is formed so that part of the base end positioned on the main shutter section 34d1 becomes a horizontal surface (a section indicated by the symbol S2 in figure 70C), and the remaining section is slanted from the leading edge of the horizontal surface as illustrated in Fig. 70C where the engaged protruding section 34d1B is omitted. In this configuration, unlike when the slanted base end of the shutter deformation section 34d2 is directly connected with the main shutter section 34d1, it is possible to prevent the stress from being concentrated in the connecting position between the slanted base end of the shutter section. shutter deformation 34d2 and main shutter section 34d1 when the base end side of shutter deformation section 34d2 wobbles.
[0370] Shutter deformation section 34d2 is configured with a cantilever-shaped part section (a section having the length indicated by the symbol L in figure 70a) extending to the rear side in the insertion direction of the storage container. of developer as the base end of the main shutter section 34d1. The deformation section of the plug 34d2 is slanted so that it goes outward from the base end side to the rear side in the insertion direction.
[0371] The free ends of the shutter deformation section 34d2 are integrated by a connecting plate section 34d2a that connects them laterally. In the center section of the connecting plate section 34d2a in the connection direction, a plug release section 34d21 is arranged to face the plug release stimulus section 72b (see figure 5) which is configured with a trapezoidal rib disposed on the side. of the cap receiving section 73. On both sides in the connecting direction, as will be described later, the cap sections 34d22 are arranged for securing the shutter 34d so as to carefully prevent opening of the toner discharge opening W.
[0372] The 34d21 plug release section is formed to have a triangular cross section. Running in the plug release stimulus section 72b (see figure 5) arranged alongside the cap receiving section 73, the plug release section 34d21 switches the shutter deformation section 34d2 from a tilted state to a horizontal state, from so that the engagement between the cap section 34d22 and an engagement end surface 34n1 (see figures 69A and 69B) positioned on the wide-width box section 34n which is present at the bottom of the cap section 34Y can be released. Thus, shutter 34d can move in the opening or closing direction of the toner discharge opening W.
[0373] The engagement end surface 34n1 positioned on the wide-width box section 34n is arranged as a section to restrict the movement of the shutter 34d towards the toner discharge opening opening W in the state in which the discharge opening toner container W is closed.
[0374] Figures 71B and 71C are views to explain the relationship between the engagement end surface 34n1 and the plug section 34d22 on the side of the shutter deformation section 34d2. At the time of closing the toner discharge opening W illustrated in Fig. 71C, provided that the shutter deformation section 34d2 on the shutter side 34d in the slanted state as the initial state, the plug section 34d22 positioned at the slanted free end facing towards the engagement end surface 34n1, and the shutter 34d cannot move independently. Thus, the state in which the toner discharge opening W is not carefully opened is maintained.
[0375] Furthermore, as illustrated in figures 69B and 71B, when the shutter 34d moves in the direction of the opening of the toner discharge opening W, the front end 34d1d of the main shutter section 34d1 in the moving direction contacts with the engagement end surface 34n1, and thus the moving position of the main shutter section 34d1 can be specified. Fig. 71C illustrates the case where the shutter 34d moves in the direction of closing the toner discharge opening W. In this case, the free end section of the shutter deformation section 34d2 becomes slanted, and so the section of plug 34d22 positioned in the free end section contacts the surface of the hitch end 34n1. Thus, shutter movement 34d is stopped unless plug release section 34d21 is pushed.
[0376] The seal material 36 is composed of a rectangular parallelepiped-shaped body attached to the main obturator section 34d1. As the sealing material 36 impinges against the rib W1 illustrated in figure 67, the end section is bent and suspended, and a section other than the end section comes into pressing contact with the rib W1 and thus is deformed with deviation in the direction of the toner discharge opening W in the friction contact state. The sealing material 36 is an elastic seal made of a flexible material. As the material, a high density microcell urethane sheet is employed in view of the slip property and the surface elasticity.
[0377] The sealing material 36 has the length (the length indicated by the symbol L1 in figure 70A) that the leading end in the direction of closing the toner discharge opening W by the shutter 34d protrudes to the far outer side of the main end of the main shutter section 34d1. The protruding leading end section is a section that easily suspends when bumping against rib W1 disposed on the circumferential edge of the toner discharge opening W.
[0378] The plug 34d is stored inside the wide-width box section 34n positioned in the lower portion of the wide-diameter cylindrical section of the cap section 34Y and moves in a glidable manner.
[0379] In the wide-width box section 34n, between the four wall surfaces arranged on the side surface, two wall surfaces facing the longitudinal direction (the cylinder axis direction of the cover section) are opened. Particularly, since the wall surface is partially left in the corner on the bottom side, an opening extending in the horizontal direction is formed in most of the wall surface on the side of the toner discharge opening W. The opening is formed of so that two surfaces of the side surface and the bottom surface on the side of the toner discharge opening W in the longitudinal direction of the wide-width box section 34n are cut.
[0380] However, in figures 20, 68, 69A, 69B and 71A, the side projections 34c for restricting the putting of the cap section 34Y in the direction of rotation in the body of the imaging apparatus 100 (the cap receiving section 73) are formed on both side sections of the cap section 34Y, respectively.
[0381] The side bosses 34c are positioned on both sides in a right angle direction in the same plane as a column direction of the positioning holes 34a and 34b on the circumferential surface of the medium diameter cylindrical section, has a triangular shape in a planar view. And it has the top section at the position away from the circumferential surface of the cylindrical section of medium diameter from the head section of the top section 34Y to the rear side.
[0382] On the slanted surface of the side boss 34c, a rising edge angle of a slanted piece beyond the top section is greater than a rising edge angle of a slanted piece positioned on the head section side of the cap section 34Y in front of the top section.
[0383] The slanted piece of the head section is disposed to the side of the cap receiving section 73 and can move while contacting the side protrusions 34c with a thrust member (not shown) which is subjected to contraction behavior by stimulus of tensile strength. That is, if a section having a small inclined angle, called the inclined plane, faces the contracting member when contracting towards the contracting member, the inclined plane can enter with respect to the contracting member without any resistance. If the top section of the inclined plane goes beyond the contraction member, the inclined surface on the back side is engaged with the contraction member, the resistance of movement from the retaining member abruptly decreases after going beyond the retaining member, and a sensation of resistance when fitted into the retaining member, called a clicking sensation, is caused.
[0384] In the present embodiment, of the slanted pieces of the rear boss, the angle of the slanted piece on the side of the head section is set at 30°, and the angle of the slanted piece on the rear side is set at 45°.
[0385] In figures 20, 68, 69A, 69B and 71A to 71C, reference numerals 34g and 34h are convex sections that are disposed on both sides of the bottom section of the cap section 34Y and are to ensure incompatibility of the 32y developer storage container (the developer storage container).
[0386] The convex sections 34g and 34h are sections for judging whether or not the 32Y developer storage container assembly operation on the developer storage container storage unit 70 is correct. If an adjustment state in an adjustment section (not shown) arranged on the side of the developer storage container storage unit 70 is normal, the developer storage container, in which toner of a predetermined color is stored, is specified. in a predetermined position it is mounted in that position, and it is judged to have been mounted correctly. Thus, it is possible to prevent an erroneous operation, called erroneous installation, in which the color of the toner stored in the developer storage container is not mounted in a predetermined mounting section.
[0387] However, the shutter 34d can be maintained in the state where the toner discharge opening W is closed by the body side shutter closing mechanism 73d illustrated in figures 72 to 75d. The body side shutter closing mechanism 73d is arranged to solve a problem where the toner container 32Y is withdrawn from the apparatus body 100 while the toner discharge opening W is not completely closed, for example at the time of replacement from the developer storage container.
[0388] In Figure 72, the body side shutter closing mechanism 73d (a shutter interleaving mechanism) is disposed in the bottom section inside the cap receiving section 73 and on the upstream side of the discharge opening. W toner in the 32Y developer storage container mounting direction.
[0389] In figure 72, the body side shutter closure mechanism 73d is a pair of horseshoe-shaped members arranged to face each other in the left-to-right direction of figure 72 and is configured to be swivel about a 73d3 support shaft on which a torsion spiral spring is installed.
[0390] The body side shutter closure mechanism 73d (the shutter interleaving mechanism) includes a first interleaving section 73d1 formed on one end side and a second interleaving section 73d2 formed on the other end side.
[0391] In the interleaving sections, at the time of the opening/closing operation of the shutter 34d in the developer storage container 32Y, the engaged protruding section 34d1b of the shutter 34d is interleaved by the second interleaving members 73d2, and a vertical surface (a surface where a leading end section of the exit line symbol 34YG in Fig. 73 is positioned) of guide rail 34YG (see Figs. 68, 69A, 69B and 71A to 71C) of cap section 34Y is interleaved by first interleaving members 73d1 (the state illustrated in figure 73). At the time of opening/closing operation of shutter 34d, the positions of shutter 34d of cap receiving section 73 and cap section 34Y are decided, and thus the opening/closing operation can be smoothly performed.
[0392] Figures 72 to 74 are views illustrating an operation of the body side shutter closing mechanism 73d (the shutter interleaving mechanism) when opening or closing the shutter 34d.
[0393] At the time of the shutter opening operation 34d, as illustrated in figure 72, in conjunction with the 32Y developer storage container assembly operation in a white arrow direction, the first interleaving members 73d1 first come into contact with a leading end 34YG1 (see figures 68, 69A, 69B and 71A to 71C) of the guide rail 34YG of the plug 34d, and then, as will be described later, the second intercalating members 73d2 contact the protrusions 34d1b1 positioned in the sections protruding engagements 34d1B from shutter 34d.
[0394] As illustrated in Figure 73, when the 32Y developer storage container assembly operation proceeds in the direction of the white arrow, the body 73d side shutter closing mechanism (the shutter interleaving mechanism) rotates about a section of support shaft 73d3.
[0395] When the body 73d side shutter closing mechanism rotates, the first intercalation members 73d1 interleave the vertical surfaces (the surfaces where a leading end section of the exit line symbol 34YG in figure 73 is positioned) of the rails guides 34YG of the cap section 34Y, and the second interleaving members 73d2 interleave the side wall surfaces by contacting face with the side wall surfaces of the main shutter section 34d1 where the base ends of the engaged protrusion 34d1b are positioned while being engaged with protrusions 34d1b1 positioned on the engaged protruding section 34d1b of the plug 34d.
[0396] Thereafter, although not shown, the shutter 34d contacts the wall section formed around the toner feed opening on the side of the cap receiving section 73 and thus stops movement in the mounting direction. Then, the vertical surface of the guide rail 34YG is interleaved by the first interleaving sections 73d1, and the movement of the plug 34d in the cap-receiving section 73 is restricted (the plug 34d does not nine absolutely in the longitudinal direction).
[0397] In the state that the movement of shutter 34d is restricted, when the 32Y developer storage container moves in the mounting direction, the shutter 34d whose movement in the mounting direction is stopped moves in a relative direction. to the movement of the cap section 34Y in the mounting direction. Furthermore, when the cover section 34Y moves to the front side in the mounting direction more than the shutter 34d whose movement is stopped, the toner discharge opening W is opened as illustrated in figure 74.
[0398] At this time, as illustrated in Figure 74, the vertical surfaces of the cap section 34Y are interleaved by the first intercalation members 34d1, and the protrusions 34d1b1 positioned on the engaged protrusion section 34d1b of the shutter 34d are engaged by the second intercalation members 73d2. Since the shutter opening operation 34d is performed in the state where the shutter 34d is interleaved, the positions of the shutter 34d and the cap section 34Y in the cap receiving section 73 are decided, and so the opening/ closing can be smoothly effected.
[0399] However, when extracting (separating) the developer storage container 32Y from the developer storage container storage unit 70 (the lid receiving section 73), the operation is performed in a reverse procedure to the procedure. of assembly. That is, the operation of the body-side shutter closing mechanism 73d (the shutter interleaving mechanism) in accompaniment with the shutter closing operation 34d is performed in the order of figures 74, 73 and 72.
[0400] The sealing state of the sealing member 36 at the toner discharge opening W at the time of the shutter opening/closing operation will be described in connection with the shutter movement position 34d with reference to figures 75A to 75D.
[0401] Figure 75A illustrates the state in which the toner discharge opening W of the cover 34 is closed by the shutter 34d. In this state, as long as the developer storage container is not loaded into the lid receiving section 73, the shutter 34d closes the toner discharge opening W. As long as the sealing material 36 is in pressing contact with the rib W1 positioned on the circumferential edge of the toner discharge opening W, the state where the shutter 34d is in close contact with the toner discharge opening W is maintained. A dotted line in Fig. 75A represents the state in which the plug release section 34d21 of the plug 34d is pushed up by the plug release stimulus section 72b beside the plug receiving section 73. The plug deformation section 34d2 is deformed with deviation from the tilted state to the horizontal state. The plug section 34d22 positioned at the free end of the plug deformation section 34d2 is released from engagement with the engagement end surface 34n1 positioned at the wide-width box section 34n which is on the bottom side of the cap section 34Y as illustrated in figures 69A and 69B.
[0402] Thus, as described in Figures 72 to 74, it can move upwards to the position where the engaged protruding section 34d1b on the side of the shutter 34d is interposed by the second intercalating members 73d2 of the body side shutter closing mechanism 73d body side shutter closing mechanism. As described in figure 72, the movement of the shutter 34d in the mounting direction is restricted, while the cap section 34Y can move in the mounting direction, so that the toner discharge opening W is opened, and the state of the figure 75B is obtained. Fig. 75B illustrates the state in which the developer storage container is inserted towards the lid receiving section 73.
[0403] Figure 75C illustrates a state of a section indicated by the symbol C in figure 75B, that is, a state directly above the toner container starts a move operation from the main body, and shutter 34d starts to close the toner discharge opening W during operation. In Fig. 75C, when the shutter 34d is still moving in the closing direction of the toner discharge opening W, the corner (a section of groove lines) of the sealing material 36 on the leading end side impinges against the rib W positioned at the circumferential edge of the toner discharge opening W and thus is trapped (suspended) between rib W1 and the upper sealing surface.
[0404] Figure 35D illustrates the state in which the toner discharge opening is completely closed by shutter 34d. At the time of completion of the closure, the corner of sealing material 36 on the leading end side is caught in and comes into close contact with the side of rib W1. The leading end surface of the sealing material 36 is pulled by the trapped and deformed section of groove lines, and suspends to cover the contact section between the rib W1 and the sealing material 36 when the cap section 34Y is viewed from from the front.
[0405] As a result, since the toner discharge opening W is sealed by a sealing material 36 until the developer storage container is completely assembled, the toner can be prevented from careless leakage from the toner discharge opening W .
[0406] The shutter mechanism according to the present seventeenth embodiment is the invention to solve the third problem mentioned above. In the present embodiment, by the configuration where the rib W1 is disposed on the circumferential edge for the toner discharge opening W used as the existing component and the configuration of the sealing material 36 having a section that is secured by impinging against the rib W1 for the sealing material used as the existing component, adhesion at the toner discharge opening increases without adding any other components, and thus toner leakage can be prevented with a high degree of certainty.
[0407] Particularly, since the toner discharge opening W is hexagonal in shape, the leading end of the seal material 36 concentrates a charge causing a twist and is easily rotated, and the twist can be caused while relieving the slip resistance in the full end section in continuity with the top section of the hexagon in which the load is concentrated. Thus, adhesion on the full circumferential edge of the toner discharge opening W can be ensured. SIXTEENTH MODE
[0408] In the following, an embodiment in which an ID chip as another invention is mounted in the developer storage container according to a fifteenth embodiment will be described.
[0409] In the present embodiment, a connector, on the cap receiving side, to which an electrical connection relationship with a 2035 ID chip illustrated in figures 76A and 76B is attached, increases the combination of the connection position, and the failure contact by the toner at the connecting position is prevented. A description will be made in connection with this configuration.
[0410] Figures 76A and 76B are front views illustrating a configuration of the 2035 ID chip and a 2032Y toner container in which the 2035 ID chip is mounted. In the same figure, the ID chip 2035 is configured so that, with respect to a central section of a rectangular terminal board body, a terminal 2035a is provided on the right, and a non-contact type communication area (a section of antenna) 2035b such as a wireless type is provided on the left (see figure 76A). As long as the contact type and the non-contact type are provided, there are the following merits. To write to the ID chip in a toner assembly or filling process in a toner container plant, toner or similar information is written to the ID chip by non-contact communication during an assembly line operation. Thus, the manufacturing speed can be remarkably improved, and thus an inexpensive toner container having a low manufacturing cost can be produced. However, within the imaging apparatus, an inexpensive non-contact type electronic substrate can be employed in a body-side communication device, thereby contributing to the cost reduction of the imaging apparatus.
[0411] In the following, a configuration of mounting the ID chip in the toner container according to the sixteenth modality will be described. The 2035 ID chip has 2035d semicircular notches in a central section. As illustrated in Fig. 76B, the 2035 ID chip is retained on the leading end surface of a 2034Y cap section of the 2032Y toner container to be slightly movable in the horizontal direction which is the longitudinal direction. As the retention method, the ID chip 2035 is sandwiched and retained between two flange pins 2034f, which are disposed almost in the center of the relevant leading end surface, at the positions of the notches 2035d. A gap between the two 2034f flange pins is larger than the shorter width between the two 2035d notches, and so the 2035 ID chip is retained in the 2034Y cap section with a setback.
[0412] However, in a 2073 cap receiving section of the developer storage container storage unit, as will be described later, a hole through 2073f that exposes a 2073e connector (which is not shown in figure 77 for convenience) used as an ID chip electrical connection section 2035 and a wall section 2073g are arranged as illustrated in figure 77.
[0413] The 2073g wall section is a section to protect an area surrounding the 2073e connector that will be described later, and when the 2073e connector that will be described later is exposed through the hole through 2073f, the 2073g wall section blocks toner from penetrate the 2073e connector.
[0414] The hole through 2073f is a place that allows the 2073e connector disposed on a common electrical substrate that will be described in figure 78 to be exposed and facing the 2035 ID chip.
[0415] Figure 78 is a view illustrating a configuration of connector 2073e disposed on the common electrical substrate. In the same figure, connector 2073e includes a plurality of endplates 2073e1 disposed in connector body 2073e0. As the 2073e1 endplate a curved flexible metal plate is used having excellent conductivity.
[0416] The 2073e connector has a configuration to perform the positioning at the time of contact with the 2035 ID chip, which will be described below.
[0417] In Figure 78, in an area surrounding the terminal plate 2073e1 arranged in the connector 2073e or part thereof, the wall section 2073g shown in Figure 77 is arranged, and a part of the wall section 2073g, pins 2073e3 are formed which are adjustable in the 2035b and 2035c positioning holes (see figures 76A and 76B) arranged on the side of the 2035 ID chip.
[0418] The 2035b and 2035c positioning holes are for positioning contact with the 2073e1 terminal plates on the 2073e connector on the 2035a terminal on the 2035 ID chip side. In order to make it easier to adjust the 2073e3 positioning pin, one is formed one round hole, and the other is formed from an elongated hole. In Fig. 79 which will be described later, the flange pin 2034f is secured to a concave section 2035a and protrudes from a retaining member 2034k. A reference numeral 34q represents a pedestal of retaining member 2034k.
[0419] A 2073e connector on the common electrical substrate side is connected with the 2035 ID chip in a state illustrated in figure 79. In figure 79, when the lid section 2034Y of the developer storage container is inserted into a section of cap receiving section 2073, positioning pins 73a and 73b on the side of cap receiving section 2073 are inserted into positioning holes 34a and 34b in cap section 2034Y, and thus cap section 2034Y is positioned on receiving section of cover 2073.
[0420] When the 2034Y cap section is further inserted, the 2073e positioning pins 2073e of the 2073e connector move into the 2035b and 2035c positioning holes on the side of the 2035 ID chip, and thus the position of the 2035a1 terminals on the side The 2035 ID chip matches the position of the 2063e1 terminal boards on the 2073e connector, thus preventing contact failure caused by imperfect matching of positions.
[0421] As the 2034Y cap section is inserted, the 2073g wall section positioned around the 2073e connector not only covers an area surrounding the connector, but also an area surrounding the 2035 ID chip as indicated by an alternative long dashed line and two short dashed lines in figure 79. In addition, the 2035 ID chip is installed in the upper position away from the discharge opening W. Thus, it is possible to prevent the scattered toner from the discharge opening W from adhering to the contact position between the terminals. SEVENTEENTH MODE
[0422] In the following, the toner container in which both the mentioned shutter configuration techniques in the toner container according to the fifteenth modality and in the ID chip 535 according to the fifth modality are mounted will be described as a fifteenth seventh modality.
[0423] A target configuration is a configuration related to the 73d body side shutter closure mechanism that has been described in Figures 73a 73D body side shutter closure mechanism.
[0424] Figure 80 is a perspective view viewed from the front right side in an insertion direction of a 2134Y cap in the state where the shutter 34d is closed, and Figure 81 is a perspective view viewed from the front left side in the direction of insertion of cover 2134Y in the state that shutter 34d is open. These figures are different from the previous drawings at the following points.
[0425] In figure 80, different from the configuration illustrated in figure 67, a front cover 2134P to prevent the fall of the 535 ID chip loaded into the concave section 34t is arranged on the front surface of cover 2134Y.
[0426] A configuration for mounting the 2134P front cover includes a 2134P10 thermal caulking pin disposed on the front surface of the 2134Y cover, below the center of the front surface, and a pair of main and sub-reference pins 734S3 that are disposed in positions different from the 2134P10 thermal caulking pin while sandwiching the 34t concave section as illustrated in figure 82. After the 2134P front surface cover is fixed, the 2134P10 thermal caulking pin becomes a state where the leading end is crushed by a jig while being heated, but an uncrushed state is illustrated in figures 82 to 86.
[0427] In the 2134P front surface cover, holes into which pins 2134P10 and 734S3 are inserted and an opening that exposes part of the 535 ID chip to the outside are formed, respectively.
[0428] By fitting the main reference pin 734S3 and sub-reference pin 734S3 inside and inserting the thermal caulking pin 2134P10, the front surface cover 2134P is positioned in the state where the ID chip 535 is exposed to the outside . The 2134P10 thermal caulking pin is heated and compressed so that the 2134P front surface cover is fixed to the front surface of the 2134Y cover.
[0429] In the holes, beside the 2134P front surface cover, into which the pins are fitted, one of the reference pins is a round hole, and the other is an elongated hole, a longitudinal direction of which is horizontal. In addition, the 2134P10 Thermal Caulking Pin insertion hole is slightly larger in diameter than the 2134P10 Thermal Caulking Pin.
[0430] By the fixing state, even if the 2132Y toner container is inserted or separated from the toner container storage unit, the 535 ID chip does not fall out, and the communication or electrical connection of the exposed ID chip to the exterior through the opening can be effected.
[0431] However, the structure related to the 73d body side shutter closing mechanism includes a guide rail 2134YG disposed on the side surface of the narrow width 34Y1 box of the 2134Y cover.
[0432] Guide rail 2134YG has a different configuration from guide rail 34YG illustrated, for example, in figure 68. As illustrated in figures 80 and 81, guide rail 2134YG includes a protruding section 2134YG3 that is configured to protrude into the front side more than the main end surface of the narrow-width box section 34Y1 and has a protruding portion going around towards the center side. The protruding sections 2134YG3 are arranged symmetrically on both sides of the narrow-width 34Y1 box.
[0433] Furthermore, as a different configuration from the configurations of the above modes, as illustrated in figure 83, in the position (the position indicated by a reference number 2134P3) facing the engaged stresses section 34d12b of the shutter 34d on the circumferential surface of the section 34Y2 medium diameter cylindrical section is formed a concave section that has the outside diameter smaller than the outside diameter of the 34Y2 medium diameter cylindrical section. The circumferential surface 2134P3 forming the concave section is configured not to interfere with the rotation of an insert member 73d2 disposed in the body side shutter closure mechanism 73d illustrated in Fig. 72.
[0434] In this configuration, when the cover 2134Y is loaded into the cover receiving section 73 of the apparatus body in the same procedure as illustrated in figures 72 to 74, the cover 2134Y is interposed by the closing mechanism of the side shutter of the body mechanism. 73d body side shutter closure. Figures 84 to 86 are views corresponding to figures 72 to 74 illustrating the loading state of the cap section 34Y used in the above configuration.
[0435] At the time of the shutter opening operation 34d, firstly, as illustrated in figure 84, in conjunction with the 32Y developer storage container assembly operation in the direction of the white arrow, the first interleaving members 73d1 come into contact with protruding sections 2134YG3.
[0436] After that, as illustrated in figure 85, when the 32Y developer storage container assembly operation proceeds in the white arrow direction, the body 73d side shutter closing mechanism (the shutter interleaving mechanism) is pushed by the protruding sections 2134IG3 and so rotates in the support shaft section 73d3.
[0437] When the body 73d side shutter closing mechanism rotates, the first insert members 73d1 sandwich the vertical surfaces of the guide rails 2134YG continuing from the projecting section 2134YG3, and the second insert members 73d2 insert the wall surfaces sides of the main shutter section 34d1 while being engaged with the lugs 34d1b1 positioned on the engaged projecting section 34d1b of the shutter 34d.
[0438] Thereafter, the shutter 34d contacts the wall section (not shown) formed around the toner feed opening next to the cap receiving section 73 and thus stops movement in the mounting direction. At this time, the vertical surfaces of the 2134YG guide rails are interleaved by the first interleaving sections 73d1.
[0439] In the state where the movement of the shutter 34d is stopped, when the toner container 2132Y moves in the mount direction, the shutter 34d whose movement in the mount direction is stopped moves selectively when viewed from the section of cover 2134Y, and the narrow width box section 34Y12 of the cover section 2134Y moves to the front side 34d. By relative movement, as illustrated in Fig. 86, the toner discharge opening W is opened.
[0440] At this time, as illustrated in Figure 74, the vertical surfaces of the cap section 2134Y are interleaved by the first intercalation members 73d1, and the protrusions 34d1b1 positioned on the engaged protruding section 34d1 of the shutter 34d are interleaved by the second intercalation members 73d2 . Since the shutter opening operation 34d is performed in the state where the shutter 34d is interleaved, the postures of the shutter 34d and the cap section 2134Y in the cap receiving section 73 are decided, and so the opening/closing operation shutter 34d can be smoothly effected.
[0441] However, when extracting (separating) the developer storage container 2132Y from the developer storage container storage unit 70 (the cap receiving section 73), the operation is carried out in a reverse procedure to the assembly procedure . That is, the operation of the body side shutter closing mechanism 73d (the shutter interleaving mechanism) in accompaniment with the shutter closing operation 34d is performed in the order of figures 86, 85 and 84.
[0442] In the configuration illustrated in Figure 81, since the protruding section 2134YG3 that is present at the front end of the guide rail 2134YG protrudes to the front side farthest from the front surface of the narrow-width box section 34Y12, the time of start of rotation of the 73d body side shutter closing mechanism is delayed. That is, since the protruding section 2134YG3 protrudes from the front surface of the narrow-width box section 34Y12 to the outside, when the cover section 2134Y is pulled out, a period of time when the rotation of the first interleaving section 73d1 is interrupted by protruding section 2134YG3 is longer, and shutter 34d remains interleaved for a longer time compared to when protruding section 2134YG3 is not disposed.
[0443] When the cover section 2134Y moves in the pull-out direction, as long as the first interleaving section 73d1 faces the engaged protruding section 34d1 of the shutter 34d, the non-rotating state is maintained. For this reason, a protruding amount of the protruding section 2134YG3 is fixed so that the side shutter closing mechanism of the 73d body can be kept in the non-rotating state until the shutter 34d is completely closed, and the interleaving of the guide rail 2134YG by the first 73d1 interleaving section can be released when shutter 34d completely closes toner discharge opening W.
[0444] Since the protruding sections engaged 34d1b to the side of the shutter 34d are interleaved by the second interleaving sections 73d2 until the toner discharge opening W is completely closed by the shutter 34d, when the cover 34Y moves in the extraction direction, the shutter 34d passes through the toner discharge opening W in the interleaved state and thus closes the toner discharge opening W.
[0445] Next, a description will be made in connection with aspects of the toner used in the developer feeding device as follows.
[0446] As the toner contained in the 32Y, 32M, 32C and 32K toner containers, the toner is formed so that the following relationships hold true: 3<Dv<8 (1) 1.00<Dv/Dn<1 .40 (2), where Dv (μm) represents a volume mean particle diameter, and Dn (μm) represents a numerical mean particle diameter.
[0447] A toner particle is selected according to an image standard in the developing process and the excellent image quality is maintained, and the satisfactory developability is maintained even if the toner is shaken for a long time in the developing device. revelation. Furthermore, toner can be efficiently and safely transported without blocking the toner supply pathway.
[0448] The volume mean particle diameter and the toner numeric mean particle diameter can be measured using a typical device such as a Coulter Counter type particle diameter distribution measuring device: Coulter Counter-TA-II (manufactured by Coulter Electronics Limited); or Coulter Multisizer II (manufactured by Coulter Electronics Limited).
[0449] Furthermore, in the present embodiment, as the toner contained in the 32Y, 32M, 32C and 32K developer storage containers used is a substantially spherical toner which is formed such that an SF-1 form factor is in a range 100 to 180 and an SF-2 form factor is in a range of 100 to 180. As a result, high transfer efficiency is maintained, and the reduction in cleaning performance is suppressed. Furthermore, the toner can be efficiently and safely transported without blocking the toner supply pathway such as tube 71.
[0450] In this document, the SF-1 format factor represents the sphericity of the toner particle and is obtained by the following equation: SF-1=(M2/S)x(100π/4)
[0451] In the equation above, M is the maximum particle diameter (the largest particle diameter in unequal particle diameters) in a toner particle design plane, and S is a design area of the toner particles. Therefore, the toner particle whose SF-1 format factor is 100 is perfectly spherical, and the degree of sphericity decreases as it becomes larger than 100.
[0452] The SF-2 format factor represents the irregularity of the toner particle and is obtained by the following equation. SF-2=(N2/S)x(100/4π)
[0453] In the equation above, N is the circumferential length in the design plane of the toner particle, and S is the design area of the toner particle. Therefore, the toner particle whose SF-2 format factor is 100 has no irregularity and the irregularity becomes wider as it becomes larger than 100.
[0454] The SF-1 format factor and the SF-2 format factor are obtained by photographing the toner particle by an “S-800” scanning electron microscope (manufactured by Hitachi, Ltd.) and analyzing the photograph of the Toner particle by a “LUSEX3” image analyzer (manufactured by Nireco Corp.).
[0455] In the first of the eight embodiments and the eleventh to seventeenth embodiments, only the toner (one-component developer) is contained in the toner container (designated as 32Y, 32M, 32C and 32K) as the developer container. However, as for the imaging apparatus which properly supplies the developing device with the two-component developer composed of toner and a carrier, the two-component developer can be accommodated in the toner container (the developer container) . Even in these cases, the same effects as in the above modalities can be obtained.
[0456] In the fifth to eighth modes and in the eleventh to seventeenth modes, some or all of the 6Y, 6M, 6C and 6K imaging units can be replaced with process cartridges. Even in this case, the same effects as in the above modalities can be obtained.
[0457] Furthermore, in the first to sixth embodiments and in the eleventh to seventeenth embodiments, rotatably configuring the container body 33Y, a configuration is made to transport the toner container in the container body 33Y in the direction of the opening A On the other hand, as in the seventh embodiment described with reference to Figures 48 and 49, the toner contained in the container body 1033Y can be conveyed towards the opening A so that the container body 1033Y is configured to be non-retainable. swivel in the toner container storage unit 70 along with the cap section 1034Y, and a transport member (e.g., a transport member which includes a plurality of transport blade members installed in a shape section and rotates in a predetermined direction) which conveys the toner towards the opening A inside the container body 1033Y is installed. Even in this case, the same effects as in the above modalities can be obtained.
[0458] Furthermore, in the above embodiments, on the substrate (designated as 35b or 535b) of the ID chip (designated as 35 or 535), a plurality of metallic buffers 35a have been arranged in-line in the vertical direction so that the position in the longitudinal direction is not misaligned. On the other hand, on the ID chip substrate, a plurality of metallic buffers 35a can be arranged in the vertical direction so that the position in the longitudinal direction is alternatively misaligned in a zigzag shape. In this case, in order to ensure the compliance of the metal dampers 35a arranged in zigzag shape, a plurality of side terminals of the body (designated 73e2 or 573e2) on the connector (designated 73 or 573e) are also arranged in zigzag shape. Even in this case, the same effects as in the above modalities can be obtained.
[0459] Furthermore, in the above embodiments, the present invention has been applied to the ID chip (the information storage device) disposed in the 32Y toner container (the developer container) or the like as the removable device detachably installed in the image forming apparatus body 100 or the like. However, the application of the present invention is not limited to this, and the present invention can be applied even to any other removable device removably installed in the body of the imaging apparatus 100 or the like as long as the information storage device be installed on the removable device similarly to the above modes. For example, in the image forming apparatus 100 illustrated in Figure 1, even when the information storage device is installed in the process cartridges 6Y, 6M, 6C and 6K as the removable device, the fixing device 20 (the processing unit attachment) as the removable device, the intermediate transfer unit 15 as the removable device, or the like, the present invention can be applied to each of them similarly to the above embodiments. Even in these cases, the same effects as in the above modalities can be obtained.
[0460] The present invention is not limited to the above embodiments, and it is obvious that the above embodiment can be appropriately switched in addition to those that have been suggested in the above embodiments. Furthermore, the number, position, shape, and the like of the component members are not limited to the above embodiments and may be exchanged for the appropriate number, position, shape, and the like to implement the present invention.
[0461] In the present disclosure, there is another invention corresponding to the fifteenth to the seventeenth modalities to solve the third problem. This can be summarized in the form of the claims as follows.
