    FIELD OF THE INVENTION
    The present invention relates to an approximately cylindrical toner container attached to a copier, a printer and an image forming apparatus such as a multifunctional peripheral that has copier, printer, and facsimile functions, and to an imaging device including a toner container. BACKGROUND
    In conventional imaging devices such as copiers, a cylindrical toner container (a toner bottle) that is separably attached to a main body of an imaging device is widely used (see, for example, Patent Document 1 and Patent Document 2). Patent Documents 1 and 2 disclose a toner container (a toner bottle) that is fixed to a body of an imaging device in a replaceable manner and that mainly includes a container body (a bottle body) and a cover unit (a holding unit). LIST OF QUOTES
    Patent Document 1: JP Patent Application Open to the Public n- H4-1681
    Patent Document 2: JP Patent Application Open to the Public No. 2002-268344 SUMMARY OF THE INVENTION TECHNICAL PROBLEM
    In a conventional toner container, when a flow-through area of a toner transport path or an opening area for a toner outlet is enlarged, it may be possible to configure a shutter unit so that the shutter unit can slide in a longitudinal direction to open and close the toner outlet in association with a fixing / separating operation of the toner container to / from a body of an imaging device in a longitudinal direction in order to fix / separate the toner container to / from the image machine body with a single action. In this case, however, the shutter unit needs to be configured to securely close the toner outlet so that the toner remaining in the toner container does not spread out of the toner container and contaminates the body of the image machine and the toner container even when the operation of separating the toner container from the body of the imaging device is carried out.
    The present invention was made in view of the above circumstances, and it is an objective of the present invention to provide a toner container from which the toner contained therein does not spread outside the toner container along with the separation operation of a body of an image forming apparatus, and an image forming apparatus including the toner container. SOLUTION TO THE PROBLEM
    In order to solve the problem described above and fulfill a purpose accordingly, a toner container according to the present invention is designed to be separably attached to a main body of an imaging device with a longitudinal direction of the container toner kept horizontal. According to the invention, the toner container includes a cylindrical container body that has an opening at one end thereof in the longitudinal direction and is configured to transport the toner contained therein towards the opening; a lid unit in which the opening of the container body is inserted and that includes a toner outlet in a bottom portion of it to discharge the toner that it discharged from the opening of the container body to an exterior of the toner container in a downward direction vertically; and a shutter unit that is retained in the bottom portion of the cover unit and moves along an outer periphery of the cover unit to open and close the toner outlet. In addition, the toner container is characterized by the members so that the lid unit includes shutter tracks to guide the shutter unit to move in the longitudinal direction to open and close the toner outlet, the shutter tracks being arranged in two respective vertical surfaces that protrude upward from respective side edges of a bottom surface where the toner outlet is formed, and each of the two vertical surfaces on which the shutter tracks are formed continues from one end of the unit shutter that is in a closed position of the toner outlet in a closed direction to a position protruding in the longitudinal direction. ADVANTAGE EFFECTS OF THE INVENTION
    In the present invention, the vertical surfaces on which the shutter tracks to guide the shutter unit open / close operation are formed continue from one end of the shutter unit that is in a closed position of the toner outlet in a closing direction to a position protruding in the longitudinal direction, so that a time slider in which the shutter closing mechanisms provided to the body of the imaging apparatus lead to the retention of the shutter unit using the vertical surfaces as references can be delayed compared to a time regulator in which the shutter closing mechanisms completely close the shutter unit. Consequently, the present invention demonstrates an effect that it is possible to provide a toner container from which the toner contained in it does not spread outside the toner container along with the operation of separating the toner container from a body of a image forming apparatus, and an image forming apparatus including the toner container.

    The exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the drawings, the same components or equivalents are indicated by the same letters or reference numbers, and their explanation will be appropriately simplified or omitted. A first modality
    A first embodiment will be described in detail below with reference to figures 1 to 44. The configuration and operation of the entire image forming apparatus are described first. As shown in Figure 1, four toner containers 32Y, 32M, 32C and 32K corresponding to their respective colors (yellow, magenta, cyan and black) are disposed separately (in a replaceable way) in a toner container holder 70 provided on the side upper part of a body of an imaging apparatus 100 (see also figures 3, 4 and 38). An intermediate transfer unit 15 is arranged below the toner container retainer 70. The imaging units 6Y, 6M, 6C and 6K corresponding to the respective colors (yellow, magenta, cyan and black) are arranged in a line so cope with an intermediate transfer belt 8 of the intermediate transfer unit 15. The 60Y, 60M, 60C and 60K toner supply devices are arranged below the 60Y, 60M and 32K toner containers, respectively. The 60Y, 60M, 60C and 60K toner supply devices supply (feed) the toner contained in the 32Y, 32M and 32K toner containers to the development devices in the 6Y, 6M, 6C and 6K imaging units, respectively.
    Referring to figure 2, the 6Y yellow imaging unit includes a 1Y photosensitive drum and also includes a 4Y charge unit, a 5Y developing device (a developing unit), a 2Y cleaning unit, and a cleaning unit neutralization (not shown), which are arranged around the 1Y photosensitive drum. The image formation processes (loading process, development process, transfer process and cleaning process) are carried out in the 1Y photosensitive drum, in which the yellow image is formed.
    The other three 6M, 6C and 6K imaging units have almost the same settings as the 6Y yellow imaging unit except that the toner colors to be used are different and the images corresponding to the respective toner colors are formed . In what follows, the explanation of the other three imaging units 6M, βC and 6K will be properly omitted, and the explanation of only the 6Y imaging unit for yellow will be given.
    With reference to figure 2, the photosensitive drum 1Y is rotated clockwise in a plane in figure 2 by a drive motor (not shown). The surface of the 1Y photosensitive drum is evenly loaded in the position of the 4Y loading unit (loading process). The surface of the 1Y photosensitive drum then reaches a position to radiate an L laser light emitted from an exposure device 7 (see figure 1), where an exposure light is scanned to form an electrostatic latent image for yellow (process of exposure).
    The surface of the 1Y photosensitive drum then reaches a standing position in front of the 5Y developing device, where the electrostatic imaging is developed and a yellow toner image is formed (development process). The surface of the photosensitive drum 1Y then reaches a sitting position in front of the intermediate transfer belt 8 and a primary transfer tilt roller 9Y, where the toner image on the photosensitive drum 1Y is transferred to the intermediate transfer belt 8 (process primary transfer). At this time, a slight amount of untransfered toner remains in the 1Y photosensitive drum.
    The surface of the photosensitive drum 1Y then reaches a position to be in front of the cleaning unit 2Y, where the remaining non-transferred toner in the photosensitive drum 1Y is collected mechanically by a cleaning blade 2a (cleaning process). The surface of the 1Y photosensitive drum finally reaches a position to face the neutralization unit (not shown), where the residual potential on the 1Y photosensitive drum is removed. In this way, a series of image formation processes carried out on the 1Y photosensitive drum is completed.
    The imaging processes are carried out on the other imaging units 6M, 60 and 6K in the same way as the yellow imaging unit 6Y. Specifically, the display device 7 arranged below the imaging units emits a laser light L based on the image information for each photosensitive drum of the imaging units 6M, 6C and 6K. More specifically, the display device 7 emits laser light L from a light phone, and radiates laser light L over the photosensitive drum through a plurality of optical elements while scanning laser light L through a mirror. polygonal being rotated. Subsequently, the colored toner images formed on the respective photosensitive drums through the development process are overlaid and transferred on the intermediate transfer belt 8. In this way, the color image is formed on the intermediate transfer belt 8.
    With reference to figure 1, the intermediate transfer unit 15 includes the intermediate transfer chain 8, four primary transfer tilt rollers 9Y, 9M, 9C and 9K, a secondary transfer copy roll 12, a plurality of pull rollers , an intermediate transfer cleaning unit and the like. The intermediate transfer belt 8 is stretched and supported by a plurality of rollers, and is moved infinitely in a direction indicated by an arrow in figure 1 in association with a rotation of the secondary transfer copy roll 12.
    The four primary transfer tilt rollers 9Y, 9M, 9C and 9K interleave the intermediate transfer belt 8 with the photosensitive drums 1Y, IM, 1C and IK, respectively, to form primary transfer tongs. A transfer tilt with a polarity opposite to a toner polarity is applied to the primary transfer tilt rollers 9Y, 9M, 9C and 9K. The intermediate transfer belt 8 moves in the direction indicated by the arrow in figure 1 and passes sequentially through the primary transfer grips of the primary transfer tilt rollers 9Y, 9M, 9C and 9K. Consequently, the toner images for the respective colors in the photosensitive drums 1Y, 1M, 1C and 1K are superimposed on the intermediate transfer belt 8 as primary transfers.
    The intermediate transfer belt 8 carrying the overlapping and transferred toner images of a plurality of colors reaches a position to face a secondary transfer roller 19. In this position, the secondary transfer copy roller 12 inserts the intermediate transfer belt. 8 with the secondary transfer roller 10 to form a secondary transfer tongs. The four-color toner image formed on the intermediate transfer belt 8 is transferred to a recording medium P, such as a transfer sheet, which has been transported to the position of the secondary transfer tongs. At this time, the non-transferred toner that has not been transferred to the recording medium P remains on the intermediate transfer belt 8.
    The intermediate transfer belt 8 then reaches the position of the intermediate transfer cleaning unit (not shown, where the non-transferred toner on the intermediate transfer belt 8 is collected. In this way, a series of transfer process carried out on the transfer belt intermediate 8 is completed.
    The recording medium P is transported to the position of the secondary transfer tongs from a feeding unit 26, which is arranged on the inner side of the body of the imaging apparatus 100, through a feeding roller 27 and a registration roller pair 28. More specifically, a plurality of embossing media P, such as transfer sheets, is stacked on the feed unit 26. When the feed roller 27, as drawn in figure 1, is rotated anti - time, the topmost recording medium P is fed to a pincer between the rollers of the record roller pair 28.
    The recording medium P transported to the pair of register rollers 28 is temporarily interrupted at the position of the tongs between the rollers, which are interrupted from triggering the rotation, of the pair of register rollers 28. The pair of register foils 28 is rotated in association with the color image on the intermediate transfer belt 8, and the recording medium P is carried in the direction of the secondary transfer tongs. The desired color image is then transferred to recording medium P.
    The recording medium P to which the color image is transferred in the position of the secondary transfer tongs is transported to the position of a fixing unit 20, where the color image transferred to the surface of the recording medium P is fixed to the medium of P engraving by heat and pressure applied by a fixing belt and a compression roller. The recording medium P is then discharged to the outside of the apparatus by means of a tongs between the rollers of a pair of discharge rollers 29. The recording medium P discharged to the outside of the apparatus by the pair of discharge rollers 29 is sequentially stacked in a stack portion 30 as an output image. In this way, a series of image-forming processes on the image-forming apparatus are completed.
    The configuration and operation of the developing device on the image forming unit are described in detail below with reference to figure 2. The 5Y development device includes a 51Y development roller to face the 1Y photosensitive drums, a 52Y doctor blade for stand in front of the 51Y developer roller, two 55Y conveyor screws arranged in the 53Y and 54Y developer storage units, and a 56Y density detection sensor to detect the toner density in the developer. The 51Y development roller includes a magnet fixed inside the roller and a sleeve that rotates around the magnet. The two-component developer G formed from the carrier and toner is stored in developer storage units 53Y and 54Y. The 54Y developer storage unit communicates with a 64Y falling toner transport path through an opening formed on an upper side of the 54Y developer storage unit.
    The 5Y developing device, configured as above, operates as follows. The 51Y development roller sleeve rotates in a direction indicated by an arrow in figure 2. The developer G, which is carried over the 51Y development roller by a magnetic field formed by the magnet, moves along the 51Y development roller. in association with the rotation of the glove.
    Developer G on developer 5Y is controlled so that the proportion (toner density) of toner in the developer is within a predetermined range. More specifically, the toner contained in the 32Y toner container is supplied to the 54Y developer storage unit via the 60Y toner supply device (see figure 3) according to the toner consumption in the 5Y developer device. The configuration and operation of the toner supply device will be described in detail below.
    The toner supplied to the 54Y developer storage unit circulates in the two developer storage units 53Y and 54Y while being mixed and shaken together with developer G (movement in a direction perpendicular to the sheet in figure 2) by the two 55Y conveyor screws. The toner in developer G adheres to the carrier by the triboelectric charge with the carrier, and is transported on the 51Y development roller along with the carrier due to the magnetic force formed on the 51Y development roller.
    The developer G carried on the 51Y development roller is transported in the direction indicated by the arrow in figure 2 and reaches the position of the 52Y doctor blade.
    After the quantity is adjusted in this position, the developer G on the 51Y development roller is transported to the position (development area) to be in front of the 1Y photosensitive drums. The toner adheres to a latent image formed in the 1Y photosensitive drums by an electric field formed in the development area. The developer G remaining on the 51Y developer roller reaches the upper side of the developer 53Y storage unit in association with the rotation of the glove, where developer G is separated from the 51Y developer roller.
    Referring to Figures 3 and 4, the 60Y, 60M, 60C and 60K toner supply devices are described in detail below. With reference to figure 3, the toner in the 32Y, 32M, 32C and 3K toner containers arranged in the toner container holder 70 of the body of the imaging apparatus 100 is suitably supplied to the respective developer devices by the toner supply devices 60Y, 60M, 60C and 60K, which are arranged for the respective toner colors, according to the consumption of toner in the development devices for the respective colors. The four toner supply devices 60Y, 60M, 60C and 60K have almost the same configurations and the four toner containers 32Y, 32M, 32C and 32K have almost the same configurations, except that the toner colors used for the forming processes are different from each other. Therefore, explanation will be given only of the 60Y toner supply device and the 32Y toner container for yellow, and the explanation of the 60M, 60C and 60K toner supply devices and the 32M, 32C and 32K toner containers for the other three colors will be omitted appropriately.
    As illustrated in Figure 4, when the 32Y, 32M, 32C and 32K toner containers 3 are attached to the toner container retainer 70 of the imaging apparatus body 100 (movement in a direction indicated by an arrow Q), a unit shutter 34d of each of the 32Y, 32M, 32C and 32K toner containers moves in association with the clamping operation. Consequently, a toner outlet W is opened and a toner supply port 73w for each of the toner supply devices 60Y, 60M, 60C and 60K (see figures 3 and 38) and the toner outlet W operate together. Consequently, the toner contained in the 32Y toner container (the same for 32M, 32C and 32K) is discharged from the W toner outlet and is accumulated in a 61Y toner tank (the same for 60M, 60C and 60K) through the toner supply ports 7 3w of the 60Y, 60M, 60C and 60K toner supply device.
    With reference to an approximately cylindrical toner bottle, and mainly includes a cap unit 34Y which is non-rotatable retained by the toner container retainer 70 and a container body (bottle body) 33Y has a fully formed gear 33c . The container body 33Y is retained to rotate with respect to the lid unit 34Y, and is driven by a drive unit 91 (which includes a drive motor, drive gear 81, and the like) to rotate in the direction indicated by a arrow in figure 3. In association with the rotation of the container body 33, the toner contained in the 32Y toner container (the container body 33Y) is transported in a longitudinal direction (transported from left to right in figure 3) by a spiral projection 33b formed on the inner circumferential surface of the container body 33Y, and the toner is discharged from the toner outlet W of the lid unit 34 Y. That is, the drive unit 91 appropriately rotates the container body 33Y from the 32Y toner container, so that the toner is properly supplied to the 61Y toner tank. The 32Y, 32M, 32C and 32K toner containers are replaced with new ones at the end of their life (when almost all the toner contained is consumed and the container becomes empty).
    Referring to figure 3, each of the 60Y, 60M, 60C, 60K toner supply devices includes the toner container retainer 70, the 61Y toner tank unit, a 62Y toner carrier screw, an end of life sensor 66Y toner and drive unit 91. The 61Y toner tank unit is arranged below the W toner outlet of the 32Y toner container to accumulate toner discharged from the W toner outlet of the 32Y toner container. The bottom portion of the 61Y toner tank unit is connected to an upstream portion of the 62Y toner carrier screw. The 66Y toner end sensor for detecting that the amount of toner accumulated in the 61Y toner tank unit becomes equal to or less than a predetermined amount is fixed to a wall surface of the 61Y toner tank unit (in a predetermined height from the bottom portion). A piezoelectric sensor or the like can be used as the 66Y toner end sensor. When a control unit 90 detects, using the 66Y toner end sensor, that the amount of toner accumulated in the 61Y toner tank becomes equal to or less than the predetermined quantity (end toner detection), the unit control unit 70 controls drive unit 91 (drive gear 81) to rotate the body of the 33Y container of the 32Y toner container for a predetermined period of time to supply the toner to the 61Y toner tank unit. When the end of toner detection by the 66Y end of toner sensor is not canceled even after the above control is repeated, the information for estimating the replacement of the 32Y toner container is displayed on a monitor unit (not shown) on the body. imaging device 100 assuming the 32Y toner container is out of toner.
    The 65Y stirring member that prevents the toner accumulated in the 61Y toner tank unit from being coherent is arranged in the center (next to the 66Y toner end sensor) of the 61Y toner tank unit. The stirring member 65Y has a flexible member arranged on an axis portion thereof. The 65Y stirring member rotates clockwise in figure 3 to stir the toner in the 61Y toner tank unit. One end of the flexible member of the 65Y stirring member comes in sliding contact with a detection surface of the 66Y toner end sensor in each rotation period in order to prevent the reduction in detection accuracy due to the adhesion of toner on the detection surface the 66Y toner end sensor.
    The 62Y toner carrier screw transports, although details are not shown in the figure, the toner accumulated in the 61Y toner tank unit in an obliquely upward direction. Specifically, the 62Y toner carrier screw conveys toner from the bottom portion (a deeper point) of the 61Y toner tank unit towards an upper side of the straight 5Y developer. The toner carried by the 62Y toner carrier screw falls through the 64 Y toner drop transport path (see figure 2) falling due to its own weight and is supplied to the 5Y developer device (54Y developer storage unit).
    Referring to Figure 4, the toner container retainer 70 mainly includes a cap retainer 73 for retaining the lid unit 34Y of the toner container 32Y, a bottle retainer 72 (container body retainer) for retaining the container body. container 33Y of the 32Y toner container, and an insertion port 71 serving as an insertion port in the operation of securing the 32Y toner container. The configuration of the toner container holder 70 (the bottle holder 72 and the cap holder 73) will be described in detail later with reference to figures 28 to 42.
    With reference to figure 1, when a body cover (not shown) disposed on a front side (a front side in a direction perpendicular to the sheet in figure 1) of the body of the imaging apparatus 100 is opened, the container retainer toner 70 (the insertion port 71) is exposed. Although each of the 32Y, 32M, 32C, 32K toner containers is maintained so that its longitudinal direction is horizontal, the fixing / separating operation of each of the 32Y, 32M, 32C, 32K toner containers is performed from the front side of the body of the imaging apparatus 100 (the fixation / separation operation using the longitudinal direction of the toner container as a fixation / separation direction).
    The bottle retainer 72 is formed so that its length in the longitudinal direction is almost equal to the length of the bottle body 33Y in the longitudinal direction. The cap retainer 73 is provided at one end of the bottle retainer 72 in the longitudinal direction (attachment direction) although the insertion port 71 is provided at the other end of the bottle retainer 72 in the longitudinal direction (attachment direction). Thus, together with the operation of fixing the toner container 32Y, the cap unit 34Y slides over the bottle retainer 72 while then passing through the insertion port 71, and after that it is fixed in the cap retainer 73.
    In the first embodiment, the antenna 73e (radio frequency identification antenna (RFID)) is mounted on the cap retainer 73 of the toner container retainer 70 on which the 32Y, 32M, 32C, 32K toner containers are mounted separately in a row (see figures 34 and 35). More specifically, antenna 73e is used for communication with an RFID 35 chip (see figures 5 and 9) which is an electronic information storage member mounted on an end face of the cap unit 34Y of the 32Y toner container.
    The RFID chip 35 (electronic information storage member) of each of the 32Y, 32M, 32C, 32K toner containers exchanges the necessary information with the 73e antenna (RFID antenna) mounted on the body of the image forming apparatus 100. Examples of information exchanged between the RFID 35 chip and the 73e antenna include information on a toner container manufacturing number, the number of times the toner container has been recycled, information on the amount of toner that the toner container can contain, a toner container batch number, and color of the toner, and information on the use of the image forming apparatus body 100. The above electronic information is stored in the RFID 35 chip (electronic information storage member) in advance before the RFID chip 35 is mounted on the body of the imaging device 100 (or information received from the body of the imaging device 100 after the chip is mounted is stored).
    Referring to Figures 5 to 26, the 32Y, 32M, 32C, 32K toner containers will be described in detail. As illustrated in figures 5 to 7, the 32Y toner container mainly includes the container body 33Y (bottle body) and the cap unit 34Y (bottle cap) arranged on the head of the container body. Referring to Figure 9, the toner container 32Y further includes, in addition to the container body 33Y and the cap unit 34Y, a stirring member 33f, a cap seal 37, the plug unit 34d, a plug seal 36 as a sealing member, and the RFID 35 chip as the electronic information storage member.
    The gear 33c, which rotates together with the container body 33Y, and an opening A are arranged at one end of the container body 33Y in the longitudinal direction (a direction perpendicular to the sheet of figure 8) (see figure 9). Opening A is provided over the head of the container body 33Y (front end position in the clamping operation), and is used to dispose of the toner contained in the container body 33Y in a space (a cavity B, see figure 25) in cover unit 34Y. The toner is suitably transported from the container body 33Y to the cavity B in the lid unit 34Y (transport is induced by rotation of the container body 33Y) as the toner in the lid unit 34Y falls below a line of predetermined stroke.
    The gear 33c is engaged with the drive gear 81 arranged on the toner container retainer 70 of the body of the imaging apparatus 100 to thereby rotate the container body 33Y about an axis of rotation. More specifically, gear 33c is formed to circulate around the circumference of opening A and includes a plurality of teeth that are radially arranged with respect to the axis of rotation of the container body 33Y. A part of the gear 33c is exposed through a notch portion 34x (see figure 19) formed on the cover unit 34Y, and is engaged with the drive gear 81 of the body of the imaging apparatus 100 in a engaged position on the lower left side of figure 8. The drive force is transmitted from drive gear 81 to gear 33c, so that the container body 33Y rotates clockwise in figure 8. In the first embodiment, drive gear 81 and gear 33c are designed as toothed gears.
    With reference to figures 5 and 6, a fastener 33d is disposed at the other end of the container body 33Y in the longitudinal direction (a bounding end in the fastening direction) so that a user can fasten fastener 33d to the fastening / separation of the fastening container. 32Y toner. The user attaches the 32Y toner container to the body of the imaging apparatus 100 by securing the holder 33d (movement of the 32Y toner container in the direction indicated by an arrow in figure 5).
    The spiral projection 33b is disposed on the inner circumferential surface of the container body 33Y (a spiral groove when viewed from the side of the outer circumferential surface). The spiral projection 33b is used to discharge the toner from opening A in association with the rotation of the container body 33Y in a predetermined direction. The container body 33Y configured as above can be manufactured by blow molding with the gear 33c of the container body 33Y, which is arranged on the circumferential surface, and the fastener 33d together.
    With reference to figures 9 and 10, the toner container 32Y according to the first embodiment includes the stirring member 33f which rotates together with the container body 33Y and which is fitted to an opening of the bottle 33a (the opening A). The stirring member 33f is formed of a pair of rod-like members extending from cavity B in the lid unit 34Y into the container body 33Y (see also figure 25). Rotating the stirring member 33f together with the opening A of the container body 33Y improves the toner discharge performance from opening A when the container body 33Y rotates.
    Referring to figures 9 and 10, the engaging members (convex portions), which are engaged with claw members 34j (see figures 12 and 26) of the lid unit 34Y in order to connect the container body 33Y and the lid 34Y to each other, are formed to circulate around the outer circumference of the bottle opening 33a of the container body 33Y. As described above, the container body 33Y is engaged with the lid unit 34Y so that the container body 33Y is rotatable with respect to the lid unit 34Y. Therefore, gear 33c rotates with respect to cover unit 34Y.
    The inside diameter of a head portion of the container body 33Y (near the position where the gear 33c is formed) is less than the inside diameter of a toner containing portion of the toner container (the position where the spiral projection 33b is formed) (see also figure 25). The flow portion (the portion surrounded by the dotted circle in figures 9 and 10), from which the inner circumferential surface protrudes inward, is provided over the head of the container body 33Y. The toner transported in the direction of opening A by the spiral projection 33b in association with the rotation of the container body 33Y is poured (the portion surrounded by a dashed circle in figures 9 and 10), into a small diameter portion the head. The toner poured into the small diameter portion of the head is agitated by the stirring member 33f, and is discarded into cavity B of the cap unit 34Y through opening A.
    With reference to figures 11 to 14, the shutter unit 34d, the shutter seal 36 (sealing member), the cap seal 37, and the RFID chip 35 (electronic information storage member) are arranged on the unit 34Y of the 32Y toner container.
    The lid unit 34Y includes an insertion portion 34z with an inner diameter larger than the inner diameter of cavity B (see figure 26), and opening A of container body 33Y is inserted into insertion portion 34z. Referring to Figures 17 and 25, the toner outlet W is formed in the bottom portion of the cap unit 34Y to allow the toner that has been discharged from opening A of the container body 33Y to be discharged outside the container. toner in a vertically downward direction (to fall by its own weight). The shutter unit 34Y for opening and closing the toner outlet W is held in a movable mode by sliding in the bottom portion of the cap unit 34Y. More specifically, the shutter unit 34d moves by relative motion in the longitudinal direction from the side of the cap unit 34Y to the side of the container body 33Y (leftward movement in figure 25) to open the toner outlet W, and the shutter unit 34Y moves by relative movement in the longitudinal direction from the side of the container body 33Y to the cap unit 34 Y (movement to the right in figure 25) to close the toner outlet W The opening / closing operation of the 34Y shutter unit (the opening / closing operation of the toner outlet W) is carried out in conjunction with the fixing / separating operation of the 32Y toner container for the toner container retainer 70 ( the body of the imaging apparatus 100) in the longitudinal direction.
    Figures 15 to 17 illustrate the operation of the shutter unit 34d from the beginning to the end of the opening of the toner outlet W. Figure 18 is a schematic diagram illustrating the operation of opening the shutter unit 34d (a shutter member deformable 34d2).
    With reference to figures 11 and 12, a first hole 34a is formed in the upper portion (ceiling portion) of the lid unit 34Y so that the first hole 34a extends BA longitudinally from the end face, which is perpendicular to the longitudinal direction of the 34Y cover unit. The first hole 34a acts as a main guide for positioning the cover unit 34Y in the body of the imaging apparatus 100. More specifically, the first hole 34a of the cover unit 34Y is engaged with a main guide pin 73a (see figures 35 and 36) of the cap retainer 73 in association with the operation of fixing the toner container 32Y to the toner container retainer 70 in the longitudinal direction.
    A second hole 34b is formed in the lower portion (bottom portion) of the cover unit 34Y so that the second hole 34b extends in the longitudinal direction from the end face, which is perpendicular to the longitudinal direction, of the cover unit. 34Y so as not to reach the position of the toner outlet W. The second hole 34b acts as a sub-tab for positioning the cover unit 34Y in the body of the imaging apparatus 100. More specifically, the second hole 34b of the cover unit 34Y is engaged with a sub-pin 73b (see figures 35 and 36) of the cap retainer 73 in association with the operation of fixing the toner container 32Y to the toner container retainer 70 in the longitudinal direction. As illustrated in figure 8, a cross section of the second hole 34b is an ellipse in which the major axis is parallel to the vertical direction.
    Using the two holes 34a and 34b configured as above, the cover unit 34Y is positioned on the toner container holder 70. Referring to figure 8, a virtual vertical line passing through the center of the first hole 34a and a vertical line virtual passing through the center of the second hole 34b are the same and the straight line identical to passing through the center of the circle of the cap unit 34Y when viewed in the plane perpendicular to the longitudinal direction.
    With reference to figure 25, the depth of the first hole 34a (or the length of the main guide pin 73a in the longitudinal direction) is greater than the depth of the second hole 34b (or the length of the sub-pin 73b in the longitudinal direction). Therefore, during the operation of fixing the toner container 32Y to the toner container retainer 70 (the cap retainer 73) in the longitudinal direction, the engagement of the main guide pin 73a with the first hole 34a as the main positioning guide is started first, and thereafter, the engagement of the sub-guide pin 73b with the second hole 34b as the subpositioning guide is started. This allows the 32Y toner container to be attached smoothly to the toner container retainer 70 (the cap retainer 73). The first hole 34a that is long in the longitudinal direction is arranged over the ceiling portion of the cover unit 34Y (a portion that is not ingrained in the toner), so that the toner carrying capacity (ability to float) in the cap 34Y is not influenced by the first hole. Although the second hole 34b which is short in the longitudinal direction is arranged in the bottom portion of the cover unit 34Y, the second hole 34b can be arranged using a small space between the end face of the cover unit 34Y and the exit position of toner W and can function completely as the subposition guide.
    With reference to figures 11 to 14, a first engagement portion 34a and a second engagement portion 34f, which act as regulators to regulate the position of the cover unit 34Y in the horizontal direction perpendicular to the longitudinal direction in the cover retainer 73 of the body of the body. image forming apparatus 100, are formed in the ceiling portion of the cover unit 34 Y. The first engaging portion 34e and the second engaging portion 34f protrude upwards in the vertical direction from the outer circumferential surface of the imaging unit. cap 34Y and are symmetrical in line with respect to a virtual vertical line passing through the center of the first hole 34a when viewed in the cross section perpendicular to the longitudinal direction (a cross section parallel to the front view of figure 8), and the first coupling portion 34e and the second engagement portion 34f extend in the longitudinal direction (a direction perpendicular to the sheet of figure 8). The first engagement portion 34e and the second engagement portion 34f are engaged with an engaged portion 73m (convex portion) of the cap retainer 73 shown in Figure 34. Therefore, the cap unit 34Y is attached to and separate from the cap retainer 73 while the posture of the cap unit 34Y in the longitudinal direction is regulated, and also the posture of the cap unit 34Y in the longitudinal direction is regulated during, when the cap unit 34Y is attached to the cap retainer 73.
    More specifically, the first engagement portion 34e (regulator) is formed just above the first hole 34a, and has an approximately rectangular cross section when viewed in the cross section perpendicular to the longitudinal direction. The first engagement portion 3e includes a projection 34el that protrudes in the longitudinal direction (attachment direction) with respect to the end face of the first hole 34a. One end of the projection 34el has a tapered shape as shown in figure 11. In contrast, the second (regulating) portions 34f are formed on both sides of the first engaging portion 34e and interspersing the first engaging portion 34e. Each of the second engagement portions 34f has an approximately L-shaped cross section when viewed in the plane in cross section which is perpendicular to the longitudinal direction (i.e., in a cross section parallel to the front view of figure 8). The first hitch portion 34e is engaged with the two hitched portions 73m formed on the lid retainer 73 so as to be fixed between the hitched portions while the second two hitch portions 34f are engaged with the hitched portions 73m to interpose the two portions 73m engaged entirely from the outside. When the lid unit 34Y is attached to the lid retainer 73 the tapered protrusion 34el of the first engagement portion 34e is engaged with the engaged portion 73m before the second portions 34f are engaged with the engaged portion 73m, so that the cover unit 34Y can be smoothly attached to the cap retainer 73.
    With reference to figures 11 to 14 again, the side projections 34c, which act as a second regulator to regulate the position of the cover unit 34Y in the rotational direction on the body of the image forming apparatus 100 (the cover retainer 73), are formed on both sides of the 34Y cover unit. The side projections 34c (the second regulator) on both sides protrude in the horizontal direction from the outer circumferential surface of the cover unit 34 Y so that both side projections 34c are arranged to be a virtually drawn horizontal line that passes a half point of a virtual line segment connecting a hole center of the first hole 34a and a hole center of the second hole 34b when viewed in the cross section perpendicular to the longitudinal direction, and the lateral projections 34c extend in the longitudinal direction (a direction perpendicular to the sheet in figure 8). The two side projections 34c (the second regulator) are engaged with side grooves 73c (groove portion) of the cover retainer 73 shown in figure 34. Therefore, the cover unit 34Y is attached to and separated from the cover retainer 73 while laying of the cover unit 34Y in the longitudinal direction is regulated and also the posture of the cover unit 34Y in the longitudinal direction is regulated during when the cover unit 34Y is attached to the cover retainer 73.
    More specifically, each end of the side projections has a tapered shape in the longitudinal direction (attachment direction) as shown in figure 11. When the cover unit 34Y is attached to the cover retainer 73, the first engagement portion 34e is engaged with the engaged portion 73m first, and then the second engaging portions are engaged with engaged portions 73m and the two lateral projections 34c having tapered shapes are engaged with the lateral grooves 73c, so that the cover unit 34Y can be fixed smoothly to the retainer cover 7 3 while the position of the cover unit 34Y is safely regulated.
    With reference to figures 11 and 2, the RFID chip 35, which is an electronic information storage member for storing various types of electronic information, is mounted on a 34k mounting portion (surrounded by a convex portion) formed between the first hole 34a and the second hole 34b on the end face of the cap unit 34Y. The RFID chip 35 is arranged to face the antenna 73e of the cap retainer 73 at a predetermined distance when the cap unit 34Y is attached to the toner container retainer 70 (the cap retainer 73). The RFID 35 chip performs non-contact communication (radio communication) with the antenna 73e while the cover unit 34Y is being retained by the cover retainer 73.
    In the first modality, because the RFID 35 chip is fixed between the first hole 34a (main guide hole) and the second hole 34b (sub-guide hole), the RFID 35 chip is affixed to the antenna 73e of the cover retainer 73 can be fixed with high precision. Therefore, it is possible to prevent a communication failure due to the positional deviation of the RFID chip 35 from the antenna 73e (RFID antenna).
    The projection 34el and the projections 34m are arranged so that they protrude more towards the side of the front face (right side in figure 25) than the convex portion (rib) formed on the circumference of the mounting portion 34k. Therefore, even when the 32Y toner container is placed with the container body 33Y side up and the lid unit 34Y side down, it is possible to prevent the RFID 35 chip from being retained in the 34 k mounting portion from entering in direct contact with a cover surface of the cap retainer 73, thereby preventing the RFID 35 chip from being damaged.
    With reference to figures 11 and 12, the convex portions 34g and 34h to ensure the incompatibility of the 32Y toner container with the toner containers of other colors are formed on the outer circumferential surface of the lid unit 34Y. The convex portions 34g and 34h are configured to be engaged with the corresponding engagement members 71g and 71h (formed in the insertion port 71 of the toner container retainer 70, see figures 27A to 27D) when the toner container fixing operation 32Y to the toner container retainer 70 is carried out correctly (when the 32Y toner container is attached to a correct position on the toner container retainer 70).
    Specifically, with reference to figures 27A to 27D, the convex portions 34g and 34h are arranged in different positions depending on each color of toner contained in the toner container (container body). The convex portions 34g and 34h corresponding to the cyan toner container are formed in positions where the convex pigs 34g and 34h can be engaged only with the coupling members 71g and 71h for cyan in the toner container retainer 70 (the insert 71C) (see figure 27C), the convex portions 34g 34h corresponding to the magenta toner container are formed in the positions where the convex pigs 34g and 34h can be engaged only with the coupling members 71g and 71h for magenta on the retainer toner container 70 (the insertion port 71M) (see figure 27B), the convex portions 34g and 34h corresponding to the yellow toner container are formed in positions where the convex portions 34g and 34h can be engaged only with the members of engage 71g and 71h for yellow on the toner container retainer 70 (the insertion port 71Y) (see figure 27A), and the convex portions 34g and 34h corresponding to the black toner container are formed in the pos ions in which convex pigs 34g and 34h can be engaged only with coupling members 71g and 71h for black on the toner container retainer 70 (the 71K insertion port) (see figure 27D).
    With the above settings, it is possible to prevent a toner container for a color fence (for example, a yellow toner container) from being attached to a toner container retainer for a different color (for example, a color container retainer). toner to cyan, thereby preventing a failure to form a desired color image, that is, it is possible to prevent the toner container from being mistakenly attached to the toner container retainer.
    Some of the incompatible convex portions 34g and 34h are cut depending on the type (color) of toner contained in the toner container in order to fulfill the incompatible function for each color. That is, portions of necessary claws are cut with a cutting tool, such as a pincer or a cutter, from the lid unit 34Y having incompatible convex portions 34g and 34h (eight claw members are formed on the left and right sides in total, as shown in figure 8), so that incompatible convex portions 34g and 34h in various ways can be formed (in the first embodiment. Four types are formed as illustrated in figures 27A to 27D).
    With the above configuration, it is not necessary to manufacture the same number of moles as the number of types of toner containers (lid units), and it is possible to form a plurality of incompatible lid unit types using a mold. Therefore, it is possible to reduce the total manufacturing costs for the plurality of types of toner containers.
    In the first embodiment, the four types of cover units illustrated in figures 27A to 27D are formed. However, it is still possible to form a plurality of types of incompatible cover units by cutting the required claw portions with various combinations of them from eight claw portions of the incompatible convex portions 34g and 34h (eight claw members are formed on the sides total left and right).
    With reference to figure 12, the notch portion 34x, in which a part of the gear 33c of the container body 33Y is exposed, is formed on the outer circumferential surface of the lid unit 34Y. Although the toner container 32Y is wired to the toner container retainer 70, the gear 33c exposed through the notch portion 34x of the cover unit 34Y is engaged with the drive gear 81 (arranged in a position indicated by a dashed line). dotted in figure 34, although details are not illustrated) arranged in the lid retainer 73, so that the drive gear 81 rotates the container body 33Y with the gear 33c together.
    With reference to figures 13 and 14, a plug housing unit 34n (housing unit) is formed in the bottom portion of the cover unit 34Y in order to house a part of the plug unit 34d (the deformable plug member 34d2) when the shutter unit 34d opens the toner outlet W. The shutter housing unit 34n is a space having an approximately rectangular parallelepiped shape protruding downwardly from the insertion portion 34z. The plug housing unit 34n (housing unit) houses the deformable plug member 34d2 while maintaining a deformed state (state in which the deformable plug member 34d2 is elastically deformed upwards using the connection position of a 34dl main plug unit. as a base point). With reference to figures 11 and 12, shutter rails 34t (see figure 19) and sliding grooves 34nl, which act as a rail unit to guide the closing / opening operation of shutter unit 34d, are formed on the surface shutter housing unit 34n. The configuration and operation of the 34d shutter unit will be described in detail below.
    Referring to figure 12, a 34n2 compression rail is formed on one side of the outer circumferential surface of the 34n plug housing unit. The compression rail 34n2 is engaged with a compression member 72c of the bottle retainer 72 (see figures 30 and 38) in order to secure the position of the cap unit 34Y by passing through the bottle retainer 72 when the 32Y toner container is attached to / separated from the toner container retainer 70. The 34n2 compression rail is formed as a concave shape (a groove), and is arranged in parallel with the attachment direction (the longitudinal direction) of the 32Y toner container. The compression rail 34n2 is formed along the longitudinal direction (clamping / detaching direction) throughout the shutter housing unit 34n. Both ends of the 34n2 compression rail are kept open without providing portions of the wall. A tapered portion 34n21 is formed at the end of the compression rail 34n2 in the clamping direction for smooth engagement of the compression member 72c with the compression rail 34n2 in the clamping operation.
    With reference to figure 11, a pressure receiving face 34n3 is formed on the other side of the outer circumferential surface of the 34n plug housing unit. A pressure receiving member 72d of the bottle retainer 72 (see figures 30 and 38) comes in sliding contact with the pressure receiving face 34n3 in order to fix the position of the cap unit 34Y that passes through the bottle retainer 72 when the 32Y toner container is attached to / separated from the toner container retainer 70.
    With the above configuration, when the 34Y cover unit is just before (or shortly after) being attached to (or separated from) the cover retainer 73 in the operation of fixing (or separating) the 32Y toner container to (or from) de) of the toner container retainer 70, in the lid unit 34Y, the compression rail 34n2 is engaged with and driven by the compression member 72c which is driven by a compression spring 72e, so that the pressure receiving face 34n3 receives the stimulus force while making sliding contact with the pressure receiving member 72. In this way, the posture of the cap unit 34Y just before (or shortly after) being attached to (or separated from) the cap retainer 73 is regulated when passing through the bottle retainer 72.
    The lid unit 34Y configured as above is connected to the container body 33Y through opening A, and discharges the toner discharged from opening A from the toner outlet W (the movement in the direction indicated by the dashed arrow in figure 3).
    In the first embodiment, with reference to figure 25, cavity B (space) in an approximately cylindrical shape is formed inside the cover unit 34Y so that cavity B extends in the longitudinal direction (a horizontal direction in figure 25) . The internal diameter of the cavity B is smaller than the internal diameter in the insertion portion 34z illustrated in figure 26 (a portion in which the head of the container body 33Y is inserted). A toner drop path C, which is columnar in shape with a constant flow passage area (cross-sectional area of the flow passage) from a lower circumferential surface of the approximately cylindrical cavity B to the toner outlet W, is formed inside the 34Y cover unit. Therefore, the toner that has been discharged from the opening A of the container body 33Y to the cavity B of the cap unit 34Y falls through the columnar toner drop path C by its own weight and is gently discharged from the toner outlet W to the outside (the 61Y toner tank unit) of the container.
    With reference to figure 19, the cap unit 34Y (the plug unit 34d and the plug seal 34 are removed and therefore not shown) is formed by welding a first member 34Y1 (see figures 20 and 21) and a second member 34Y2 (see figure 22). More specifically, the side projections 34c and the bottom portion of the first member 34Y are fitted to the notch portions 34Y2b and 34Y2c of the second member 34Y2, and an inner circumferential surface 34Y2a of the second member 34Y2 is fitted to and bonded (welded) to a portion connection 34Yla of the first member 34Y1.
    As shown in figures 20 and 21, the ring seal cap 37 as a sealing member is attached to an opposite surface of the first member 34Y1 (a surface to face the bottle opening 33a formed on the circumference of the opening A of the container body 33Y). The cap seal 37 is used to seal a gap between the opposing surfaces of the container body 33Y and the cap unit 34Y at the circumference of the opening A, and is made of elastic material such as polyurethane foam (foamed resin material).
    As illustrated in figure 20, the mounting portion 34k for mounting the RFID chip 35 is formed on the end face of the first member 34Y1. The mounting portion 34k is formed as a wall portion from which the circumference protrudes from the end FAE of the first member 34Y1. The base portions 34k2 for securing the four corners of the approximately rectangular RFID 35 chip are formed at the four corners of the rectangular wall portion within the 34 k mounting portion; Placing the RFID 35 chip in the base portions 34k2, an electronic device formed on the rear face of the RFID 35 chip (a surface to face the first member 34Y1) does not come into contact with the first member 34Y1. The RFID 35 chip is attached to the mounting portion 34k so that heat and pressure are applied to a portion of the base portions 34k2 to melt after the RFID 35 chip is placed in the base portions 34k2, and the base portions 34k2 they are cooled to be solidified and joined to the four corners of the RFID 35 chip.
    As illustrated in figures 20 and 21, shutter rails 34t (rail unit) for orienting shutter unit 34d to move in the longitudinal direction to open and close the toner outlet W are formed on both sides of the portion bottom of the first member 34Y1 (the cap unit 34Y). The shutter tracks 34t are formed on the two vertical surfaces 34s that remain on top of both side edges of the bottom surface on which the toner outlet W is formed. In other words, the shutter tracks 34t are formed using a portion of the vertical surfaces 34s. The shutter tracks 34t are formed using the upper projection surfaces provided in a protruding manner on both edges of the bottom surface (both edges in a direction perpendicular to the sheet of figure 25). The vertical surfaces 34s that remain upwards are formed on the portions of the lateral edges of the projections. The two vertical surfaces 34s formed on both side edges of the first member 34Y1 extend from the end of the shutter unit 34d, which is in a closed position of the toner outlet W in the closing direction, to the projecting position in the longitudinal direction (attachment direction) (see also figure 39).
    More specifically, two projections 34m (horn-like members) projecting in the longitudinal direction (clamping direction) from the end face of the cap unit 34Y perpendicular to the longitudinal direction are formed on the cap unit 34Y. The two projections 34m are arranged so as to insert the second hole 34b close to a bottom edge of the second hole 34b. The two vertical surfaces 34s are configured to include the respective vertical surfaces of the lateral edges of the two projections 34m. That is, the vertical surfaces at the outer edges of the two projections 34m are formed to be on the same planes as the vertical surfaces 34s on which the shutter tracks 34t are formed.
    The vertical surfaces 34s configured as above are retained surfaces that are retained by the first retaining members 73dl of shutter closing mechanisms 7 3d (shutter retaining mechanisms) of the cap retainer 73 (the toner container retainer 70) (see figure 41). That is, the posture of the shutter unit 34d of the cap unit 34Y defined in the cap retainer 73 is fixed by the shutter closing mechanisms 73d which also function as the shutter retaining mechanisms.
    Because the vertical surfaces 34s that function as the retaining surfaces are extended in the clamping direction (for the top direction in figure 41), when the 32Y toner container is removed from the toner container retainer 70, a time regulator in which the shutter closing mechanisms 73d (second retaining members 73d2) release the retention of the shutter unit 34d using the vertical surfaces 34s as references can be delayed as compared to a time regulator where the shutter closing mechanisms 73d close completely the shutter unit 34d. Therefore, it is possible to prevent the 32Y toner container from being removed from the body of the imaging apparatus 100 before the shutter unit 34d completely closes the toner outlet W. In particular, due to the tips of the two projections 34m in the longitudinal direction ( clamping direction) are located to protrude from the end face of the first hole 34a in the longitudinal direction (clamping direction), the shutter closing mechanisms 73d (the second retaining units 73d2) release the retention of the shutter unit 34d at the end of the removal of the cover unit 34Y from the cover retainer 73. Therefore, it is possible to safely prevent an error of closing of the shutter unit 34d. The configuration and operation of the 73d shutter closing mechanisms (the shutter retention mechanisms) will be described in detail below with reference to figures 39 to 41.
    The shutter unit 34d with the shutter seal 36 (sealing member) fixed on a surface to face the toner outlet W is arranged in the bottom portion of the cap unit 34Y configured as above. As illustrated in figures 15 to 17, the shutter unit 34d opens and closes the toner outlet B in association with the securing / separating operation of the 32Y toner container to the toner container retainer 70.
    More specifically, with reference to figures 23 and 24, the shutter unit 34d includes a main shutter unit in the form of a plate 34dl and the deformable shutter member 34d2, protruding from the main shutter unit 34dl, which is more thinner than the 34dl main shutter unit and elastic. The shutter slides 34dl2 being a pair are formed on both external sides of the main shutter unit 34dl, and the engagement portions of shutter tracks 34dl5 being a pair are formed on both internal sides of the main shutter unit 34dl. Shutter slides 34dl2 are projections that extend on the side portions of the main shutter unit 34dl and parallel to the insertion direction of the 32Y toner container. The engagement portions of 34dl5 plug tracks project into the main shutter unit 34dl (opposite the side where the 34dl2 shutter slides protrude) maintaining a predetermined distance from the plug seal 36. O length of the shutter sliders 34dl2 in the insertion direction of the 32Y toner container is fixed, in a state where the shutter sliders 34dl2 are mounted to the 32Y toner container, to be equal to the length between the end of one of the shutter tracks 34t and one of the convex portions 34tl formed on one of the 34t shutter tracks. The length of each of the sliding grooves 34nl formed in the plug housing unit 34n in the insertion direction is approximately equal to the length of each of the 34dl2 shutter slides.
    The shutter sliders 34dl2 of the main shutter unit 34dl are engaged with the sliding grooves 34nl (rail units) of the cover unit 34Y, and the shutter rails 34t (rail units) of the cover unit 34Y are engaged, being interleaved , with the 34dl5 plug rail engagement portions and the shutter seal 36 of the 34dl main shutter unit. Therefore, the main shutter unit 34dl opens and closes the toner outlet W by moving the shutter unit 34d along the track units 34nl and 34t.
    The shutter seal 36 as a sealing member is attached to the top face of the main shutter unit 34dl (the surface to face the toner outlet W). The shutter seal 36 prevents toner from leaking between the main shutter unit 34dl and the toner outlet W while the toner outlet is being closed by the main shutter unit 34dl (the shutter unit 34d). The plug seal 36 is made of foamed resin material or the like.
    As illustrated in figures 23 and 24, the plug seal 36 of the first embodiment is arranged so that it protrudes in the longitudinal direction (clamping direction) of one end of the plug unit 34d along the closing direction. The end of the plug seal 36 (protruding portion) contacts the wall formed in the circumference of the toner supply port 7 3w (see figure 34) when the cap unit 34Y is attached to the cap retainer 73, and functions as a sealing member to prevent the toner in the 32Y toner container from leaking to the periphery of the 73w toner supply port.
    With reference to figures 23 and 24, the deformable obturator member 34d2 of the obturator unit 34d is integrally formed in the main obturator unit 34dl and is elastically deformable in the vertical direction using the connection position between the deformable obturator member 3d2 and the unit shutter main 34dl as a base point (a portion surrounded by a dashed circle in figure 18). The deformable plug member 34d2 is disposed on the side of the container body 33Y in the longitudinal direction when compared to the main plug unit 34dl (see figure 15). The caps and plug release unit 34d21 are formed on the deformable plug member 34d2.
    The plugs 34d22 of the deformable plug member 34d2 are walls formed in the most extreme portions (tips of the deformable plug member 34d2 on the far side of the main plug unit 34dl) in the opening direction of the deformable plug member 34d2 (the left side in the figure 18). The plugs 34d22 come into contact with the contact portions 34n5 formed in the plug housing unit 34n of the cover unit 34Y, thereby regulating the movement of the plug unit 34d in the direction from the toner outlet W which is closed to open . That is, the plugs 34d22 of the shutter unit 34d are in contact with the contact portions 34n5 while the toner container 32Y remains insulated (when the toner container 32Y is not attached to the body of the imaging apparatus 100), so that the shutter unit 34d does not move itself in the opening direction to open the toner outlet W.
    The plug release unit 34d21 (cap release projection) of the deformable plug member 34d2 protrudes downwards in the vertical direction. The plug release unit 34d21 moves the plugs 34d22 upwards along with the elastic deformation upwards of the deformable plug member 34d2 when receiving an external force from below, thus releasing the contact state between the plugs 34d22 and the portions 34n5 contact point. The plug release unit 34d21 is formed between the plugs 34d22 and the connection position (connection position between the main plug unit 34dl and the deformable plug member 34d2), and is a groove projection with slopes formed in both sides along the longitudinal direction. The buffer release unit 34d21 comes into contact with a buffer release tilt portion 72b (see figures 28 and 38), which is formed on the bottle retainer 72, in association with the 32Y toner container fixing operation to the toner container retainer 70, and is pushed upward by the tilt release portion of plugs 72b (receives external force from below). Then, the deformable plug member 34d2 is elastically deformed upwards and, consequently, the plugs 34d22 are displaced upwards. Thus, the contact state between plugs 34d22 and contact portions 34n5 is released, so that the plug unit 34d can move in the opening direction.
    With reference to figures 18A to 18C, the operation of the shutter unit 34d in association with the operation of securing the toner container 32Y to the toner container retainer 70 will be described in detail below. The positions of the shutter unit 34d in figures 18A to 18 (C) correspond, respectively, to the positions of the shutter unit 34d in figures 15 to 17.
    As illustrated in figure 18A, when the operation of fixing the 1 toner container 32Y to the toner container retainer 70 (movement to the right in figure 18) is already started in the buffer release unit 34d21 of the shutter unit 34d has not reached the position of the tilt release portion of plugs 72b formed on the bottle retainer 72 (see also figures 28 and 38), plugs 34d22 of the plug unit 34d are in contact with the contact portions 34n5 and the movement of the unit shutter speed 34d in the opening direction is regulated. As illustrated in figure 18 (B), when the 32Y toner container attachment operation continues, the plug release unit 34d21 is pushed upward by the tilt release portion of plug 72b, and the deformable plug member 34d2 is elastically deformed using the connection position (a portion surrounded by a dashed circle) as a base point. Consequently, the contact state between plugs 34d22 and contact portions 34n5 is released and the plug unit 34d is allowed to move relatively in the opening direction.
    After that, the shutter unit 34d comes into contact with the wall formed in the circumference of the toner supply port 7 3w of the cap retainer 73 (see figure 34), so that the movement of the shutter unit 34d in the container retainer toner 70 (the cap retainer 73) is regulated (the shutter unit 34d does not move in the longitudinal direction at all). However, the 32Y toner container is allowed to move in the clamping direction, so that the shutter unit 34d moves relatively in the opening direction. That is, as illustrated in figure 18C, the shutter unit 34d moves relatively to the side of the toner container 32Y and the deformable shutter member 34d2 is housed in the shutter housing unit 34n (housing unit). Thus, the process of opening the toner outlet W is completed by moving the shutter unit 34d in the opening direction. At this time, the plug release unit 34d21 of the plug unit 34d is stored in a notch portion 34n6 of the plug housing unit 34n (see figure 17).
    As described above, the 32Y toner container of the first embodiment includes, in the shutter unit 34d, deformable shutter member 34d2 which is elastically deformed using the connection position of the main shutter unit 34dl as a base point, and also includes, on the deformable plug member 34d2, the plugs 34d22 to regulate the movement of the plug unit 34d in the opening direction and the plug release unit 34d21 to release the regulation. Therefore, the shutter unit 34d does not open the toner outlet W by itself while the toner container 32Y remains isolated. Instead, the shutter unit 34d opens the toner outlet W in association with the clamping operation only when the toner container 32Y is attached to the body of the imaging apparatus 100.
    The engagement portions of plug tracks 34dl5 of the main plug unit 34dl (see figure 23) also function as second covers that come into contact with a second contact portion formed in the cover unit 34Y (a portion surrounded by a dashed circle in the figures 19 and 20) and regulate a movement of the shutter unit 34d in a closing direction (the opposite direction of the direction in which the caps 34d22 make the adjustment). That is, when the shutter unit 34d transitions from the state in which the toner outlet W is open (the state shown in figure 17) to the state in which the toner outlet W is closed (the state shown in figure 15 ), the engagement portions of shutter rails 34d15 (the second plugs) of the shutter unit 34d come into contact with the second contact portion (the portion surrounded by the dashed circle in figures 19 and 20) on the bounding side in the closing direction , and the caps 34d22 of the shutter unit 34d come into contact with the contact portions 34n5 on the driving side in the closing direction. Consequently, the position of the shutter unit 34d in the closed state is fixed. At this point, the engaging portions of shutter rails 34dl5 of the shutter unit 34d come into contact with the second contact portion just after passing over the convex portions 34tl formed in the shutter rails 34t (see figures 20 and 21), so that it is possible to gain a clicking sensation in the closing of the 34d shutter unit.
    With reference to figures 19 to 21, the ribs 34p having vertical surfaces on the same virtual planes as the vertical surfaces 34s of the shutter tracks 34t (or vertical surfaces parallel to the virtual plane) are extended on the upper sides of the shutter tracks 34t in the direction longitudinal while the groove portions are interposed between the ribs 34p and the plug tracks 34t. Ribs 34p prevent the first retaining members 73dl from entering the groove portions on the upper sides of the shutter rails 34t when the first retaining members 73dl of the shutter closing mechanisms 73d (shutter retaining mechanisms) shown in figure 41 retain the vertical surfaces 34s of the shutter tracks 34t. That is, a distance between one of the ribs 34p and one of the plug tracks 34t on the same side of the first member 34Y1 between the two elements of the ribs 34p and the plug tracks 34t (a distance from the slot portion) is fixed to be more shorter than the heights of the first 73dl retaining members (the lengths in a direction perpendicular to the sheet in figure 41).
    The ribs 34p can fulfill the functions as long as the ribs 34p protrude laterally (in the direction perpendicular to the sheet in figure 25) and extend in the longitudinal direction (the horizontal direction in figure 25). Therefore, ribs 34p do not necessarily have the vertical surfaces described above.
    With reference to figures 23 and 24, the retaining portions 34dll being a pair are formed on the side of the direction of attachment of the tips on both sides of the edges of the main shutter unit 34dl of the shutter unit 34d. As illustrated in figures 39 to 41, the retaining portions 34dll are retained by the second retaining members 73d2 of the shutter closing mechanisms 73d (shutter retaining mechanisms) at the time of the opening / closing operation of the shutter unit 34d. Each of the retaining portions 34dll is formed of an engagement wall 34dlla that remains at the tip of the main shutter unit 34dl in the direction of attachment, a suppression wall 34dllb extending over the upper side of the retaining portion 34dll to be parallel the direction of attachment, and a side wall 34dllc (which also functions as a side wall of the main shutter unit 34dl).
    The retaining portions 34dll of the shutter unit 34d are retained by the second retaining members 73d2 of the shutter closing mechanisms 73 (shutter retention mechanisms) and the vertical surfaces 34s of the cap unit 34Y are retained by the first retaining members 73dl the shutter closing mechanisms 73d (shutter retention mechanisms) at the time of the opening / closing operation of the shutter unit 34d. Consequently, the postures of the shutter unit 34d and the cap unit 34Y on the cap retainer 73 during the open / close operation of the shutter unit 34d can be fixed. At this time, the second retaining members 73d2 of the shutter closing mechanisms 73d (shutter retaining mechanisms) retain the side walls 34dllc of the retaining portions 34dll (the main shutter unit 34dl), and the suppression walls 34dllb work to suppress the vertical movement of the retaining portions 34dll with respect to the second retaining members 73d2. The engagement walls 34dlla of the retaining portions 34dll are engaged with the second retaining members 73d2 which will be described later.
    With reference to figures 17 and 41, the toner outlet W of the cover unit 34Y, which is opened and closed by the shutter unit 34d configured as above, has a hexagonal shape when viewed from below in the vertical direction.
    More specifically, a downwardly protruding edge portion 34r is formed over the circumference of the toner outlet W of the cap unit 34Y. The edge portion 34r has apex portions 34rl on both sides in the longitudinal direction (the vertical direction in figure 41). Each end 34rl has a pointed shape that is pointed in a longitudinal direction to be separated from the center of the toner outlet W. More specifically, when viewed from the bottom in the vertical direction, the edge portion 34r is an edge portion hexagonal having parallel portions 34r2 that are opposite each other along the longitudinal direction (the vertical direction in figure 41), and the two apex portions 34rl that are positioned at the ends opposite each other in the longitudinal direction. The toner outlet W has a hexagonal shape that follows the hexagonal shape of the edge portion 34r.
    In this way, the tips 34rl, which are formed on the edge portion 34r on the circumference of the toner outlet W the longitudinal direction (the direction in which the shutter unit 34d is opened and closed), have pointed shapes, so that when the shutter unit 34d is closed, the shutter seal 16 attached to the shutter unit 34d first contacts the edge portion 34r at the apex portion of the pointed shape 34rl with a small area, and after that, the contact area slider increases gradually. Therefore, the plug seal 36 is less likely to be peeled or damaged due to contact with the edge portion 34r. When the plug unit 34d is opened, the area of the sliding contact gradually decreases, so that damage to the plug seal 36 due to contact with the edge portion 34r is reduced.
    With reference to figure 43, a sealing member 7 6 made of foamed resin material is attached to the circumference of the toner supply port 73w of the cap retainer 73 (see also figure 38), so that it is possible to prevent toner spread from the toner supply port 73w connected to the toner outlet W of the toner container 32 Y. Even when the edge portion 34r of the cap unit 34Y comes in sliding contact with the sealing member 76 disposed on the circumference of the toner supply port 73w in association with the operation of fixing the toner container 32Y in the longitudinal direction, the edge portion 34r comes in sliding contact with the sealing member 76 first in the apex portion in the pointed shape 34rl with a small area, and after that, the sliding contact area gradually increases. Therefore, the sealing member 76 of the 73w toner supply port is less likely to be peeled or damaged due to contact with the edge portion 34r. In addition, when the 32Y toner container separation operation in the longitudinal direction is carried out, the sliding contact area between the sealing member 76 of the toner supply port 73w and the edge portion 34r gradually decreases, in order to damage the sealing member 7 6 of the 73w toner supply port due to contact with an edge portion 34r may be reduced. In figure 43, the positional relationship between the sealing member 76 of the toner supply port 73w and the toner outlet W is illustrated in a vertically inverted manner for reasons of ease of understanding.
    Therefore, it is possible to safely prevent the toner (or remaining toner) housed in the 32Y toner container from spreading outwards in association with the securing / separating operation of the 32Y toner container to / from the body of the forming machine. image 100.
    With reference to figure 17, in the first embodiment, the edge portion 34r of the cover unit 34Y is configured so that the planes (planes in contact with the apex portions 34rl) perpendicular to the longitudinal direction (the vertical direction in figure 41) have tapered shapes so that the amount of downward protrusions gradually decreases as the distance from the center of the toner outlet W increases.
    With this configuration, even when the shutter seal 36 attached to the shutter unit 34d is rubbed by the edge portion 34r in association with the securing / separating operation of the 32Y toner container in the longitudinal direction, the shutter seal 36 is less likely to be damaged. Similarly, even when the sealing member 76 (see figure 43) disposed over the circumference of the toner supply port 73w of the cap retainer 73 is rubbed by the edge portion 34r in association with the fixing / separating operation of the toner container 32Y in the longitudinal direction, the sealing member 76 is less likely to be damaged.
    Indicating, respectively, the average volumetric particle size and the numerical average particle size of the toner contained in the toner containers 32Y, 32M, 32C, 32K per Dv (end), the toner used in the first mode is manufactured so that the following conditions are satisfied. 3 <Dv <1.40 (1) 1.00 <Dv / Dn <1.40 (2)
    Therefore, toner particles appropriate for an image pattern are selected in a development process to maintain good image quality, and even when the toner is agitated in the development device over a long period of time, good development capacity can be maintained. In addition, toner can be safely and effectively transported without blocking the toner supply path such as a tube 75.
    The average volumetric particle size and the numerical average particle size of toner are measured using, for example, the Coulter-counter particle size distribution measuring device such as "COULTER COUNTER TA-2" (Beckman Coulter, Inc. ) or "COULTER MULTISIZER 2" (Beckman Coulter, Inc.).
    In the first mode, to the extent that the toner contained in the 32Y, 32M, 32C, 2K toner containers, approximately spherical toner with an SF-1 form factor in a range of 100 to 180 and with an SF-2 form factor in a range of 100 to 180 is used. Therefore, it is possible to maintain high transfer efficiency and prevent a reduction in cleaning performance. In addition, toner can be safely and efficiently transported without blocking the toner supply path such as the 75 tube.
    The SF-1 form factor represents the degree of sphericity of a toner particle, and is obtained by the following equation: SF-1 = (M2 / S) X (100π / 4). In the above equation, M is the maximum particle size in a toner particle projection plane (the largest particle size among several particle sizes), and S is an area of the toner particle projection plane. Therefore, a toner particle with an SF-1 form factor of 100 is perfectly spherical, and the sphericity decreases as the form factor becomes greater than 100. The SF-2 form factor represents the irregularity of a toner particle, and is determined by the following equation: SF-2 = (N2 / S) X (100 / 4π).
    In the equation, N is the circumferential length in the projection plane of the toner particle, and S is an area of the projection plane of the toner particle. Therefore, a toner particle with an SF-2 form factor of 100 has no irregularities, and the irregularity increases as the form factor becomes greater than 100.
    The SF-1 form factor and SF-2 form factor are obtained by photographing the toner particles using an electronically scanned "S-800" microscope (manufactured by Hitachi, Ltd.) and analyzing the photograph obtained from the toner particles by an image analyzer "LUSEX3" (manufactured by Nireco Corporation).
    The toner container holder 70 (the bottle holder 72 and the cap holder 73) will be described in detail below with reference to figures 28 to 42.
    As described above with reference to figure 4, the toner container retainer 70 includes the bottle retainer 72, the cap retainer 73 and the insertion port 71. The toner container 32Y is attached to the toner container retainer 70 a from the insertion port 71 in the longitudinal direction as the clamping direction with the lid unit 34Y positioned at the conductive end of the container body 33Y, while being held by a user holding the holder 33d so that the longitudinal direction of the toner container 32Y is parallel to the horizontal direction. The 32Y toner container inserted from the insertion port 71 is pushed into the cap retainer 73 by the user while sliding over the face of the bottle retainer 72a of the bottle retainer 72 (see figures 30 and 31). With reference to figures 28 and 29, the bottle retention faces 72aY, 72aM, 72aC and 72aK are formed in the bottle retainer 72 for the respective colors, and the 32Y, 32M, 32C, 32K toner containers are inserted in the respective faces bottle retention (in a direction indicated by an underlined arrow). With reference to figure 33, the bottle retainers 73Y, 73M, 73C, 73K are formed in the cap retainer 73 for the respective colors. The 32Y, 32M, 32C, 32K toner containers are inserted into the respective bottle holders (in a direction indicated by an underlined arrow), so that each of the cap units 34Y, 34M, 34C and 34K is retained in a different way non-rotating in the inserted position.
    Referring to Figures 28 to 32, the bottle holder 72 of the toner container holder 70 includes the bottle holding face 72a, the tilt release portion of plugs 72b, the pressing member 72c, the receiving member of pressure 72d, the compression spring 72e, and a torsion coil spring 72f.
    The bottle holding face 72a functions as a sliding face of the 32Y toner container during the clamping / separating operation of the 32Y toner container, and functions as a retention unit for the rotating container body 33Y after adjusting the waste container. 32Y toner is complete.
    Referring to Figure 29, the slope release portion of plugs 72b is a trapezoidal rib formed on the upper side (bounding side in the direction of fixing the toner container 32Y) of the bottle holding face 72a. As described above with reference to figure 18, the plug release tilt portion 72b pushes the plug release unit 34d21 from the plug unit 34d upward to release the contact state between plugs 34d22 and the contact portions 34n5 in association with the operation of fixing the 32Y toner container (in order to allow the opening operation of the 34d shutter unit).
    With reference to figure 29, the compression member 72c is disposed on a side wall on the right side of the bottle holding face 72a on the downstream side in the direction of fixing the 32Y toner container. As shown in figures 30 and 32, the tip of the compression member 72c is formed to have a groove shape, and the bottom portion of the compression member 72c is connected to an end of the compression spring 72e. The compression member 72c configured as above is driven by the compression spring 72e to the left in figure 29.
    Referring to figure 29, on the other hand, the pressure receiving member 72d is disposed on a side wall on the left side of the vial retaining face 72a (the position to face the pressing member 72c) on the bounding side on direction of fixing the 32Y toner container. As shown in figure 1, the tip of the pressure receiving member 72d is formed so that two curves form an inverted V shape (the v-shaped cleavage faces diagonally on the lower right side in figure 29), and the bottom portion of the pressure receiving member 72d is connected to the torsion coil spring 72f. The pressure receiving member 72d is oscillatingly movable around the axis portion where the coil portion of the torsion coil spring 72f is inserted.
    Like the compression member 72c and the pressure receiving member 72d configured as above, the position of the 34Y drum unit just before being inserted into the cap retainer 73 is fixed when the 32Y toner container is attached to the toner container retainer. toner 70. More specifically, the compression rail 34n2 of the cover unit 34 Y (see figure 12) is engaged with the compression member 72c, so that the cover unit 34Y is compressed by the compression member 72c on the left in the figure 29. The pressure receiving face 34n3 (see figure 11) of the cover unit 34Y compressed by the compression member 72c comes in sliding contact with the pressure receiving member 72d whereby the compression force is received to fix the position of the cover unit 34Y in the horizontal direction in figure 29.
    Referring to Figures 33 to 37, the cap retainer 73 of the toner container retainer 70 includes the main guide pin 73a, the underside pin 73b, the engaged portion 73m, the side grooves 73c, the shutter closing mechanisms 73d (the shutter retention mechanisms), the 73w toner supply port, the evacuation holes 73k, the 73e antenna (RFID antenna), and the drive gear 81.
    As described above with reference to figure 11, the main guide pin 73a and the sub-pin 783b are engaged with the first hole 34a and the second hole 34b of the cover unit 34Y, respectively. Consequently, the position of the cap unit 34Y on the cap retainer 73 is fixed. With reference to figure 37, the main guide pin 73a is larger than the sub-guide pin 73b in the longitudinal direction (the positions of the guide surfaces that function as the base portions are formed in the same plane). The tip of the main guide pin 73a is formed to be tapered. Therefore, it is possible to gently attach the 32Y toner container to the cap retainer 73 in the operation of fixing the 32Y toner container to the cap retainer 73 in the longitudinal direction.
    The engaged portion 73m is engaged with the first engaging portion 34e and the second and regulating portion 34f formed on the lid unit 34Y of the 32Y toner container. Therefore, the lid unit 34Y is fixed and separated from the lid retainer 73 while the position of the lid unit 34Y in the horizontal direction is regulated. The side grooves 73c are engaged with the side projections 34c (second regulator) formed on the cover unit 34Y of the toner container 32Y. Therefore, the cap unit 34Y is attached to and separated from the cap retainer 73 while the position of the cap unit 34 Y in the rotational direction is required. In addition, the position of the cover unit 34Y in the rotational direction is regulated while the cover unit 34Y is being attached to the cover retainer 73.
    With reference to figures 34 and 38, the shutter closing mechanisms 7 3d (shutter retention mechanisms) are arranged in the bottom position inside the cap retainer 73, and on the conductive side of the toner supply port 73w in the direction of fixing the 32Y toner container. The shutter closing mechanisms 73d being a pair are approximately horseshoe members which are arranged to face each other in the horizontal direction in figure 39, and are configured to be rotatable about the support axes 73d3 in which the torsion coil springs are arranged. The first retaining members 73dl are formed at one end of the shutter closing mechanisms 73d (shutter retaining mechanisms), and the second retaining members 73d2 are formed at the other ends of the shutter closing mechanisms 73d. As described above, the retaining portions 34dll of the shutter unit 34d are retained by the second retaining members 73d2 and the vertical surfaces 34s of the cap unit 34Y are retained by the first retaining members 73dl during the open / close operation of the shutter unit. shutter 34d on the 32Y toner container, so that the postures of the shutter unit 34d and the cap unit 34Y on the cap retainer 73 are fixed during the open / close operation of the shutter unit 34d. Consequently, it is possible to smoothly perform the open / close operation.
    Figures 39 to 41 are diagrams illustrating the operation of the shutter closing mechanisms 7 3d (shutter retention mechanisms) in association with the opening / closing operation of the shutter unit 34d. As illustrated in figure 39, when the shutter unit 34d is opened, the first 73dl retaining members come into contact with the projections 34m and the second 73d2 retaining members come into contact with the 34dll retaining portions of the unit shutter 34d in association with the 32Y toner container clamping operation in the direction indicated by an underlined arrow.
    After that, as illustrated in figure 40, when the operation of fixing the 32Y toner container in the direction indicated by the underlined arrow continues, the shutter and shutter mechanisms 7 3d (shutter retention mechanisms) rotate around the support axes 73d3 , so that the first retaining members 73dl retain the vertical surfaces 34s of the projections 34m of the lid unit 34Y and the second retaining members 73d2 while being engaged with the engagement walls 34dlla of the retaining portions 34dll of the shutter unit 34d , retain the side walls 32dllc (the shutter unit 34d) of the main shutter unit 34dl (the retaining portions 34dll).
    After that, the shutter unit 34d comes into contact with the wall formed on the circumference of the toner supply port 7 3w of the cap retainer 7 3 (see figure 34). Consequently, the movement of the shutter unit 34d in the cap retainer 73 is regulated as the shutter unit 34d is sandwiched between the wall and the second retaining members 73d2 (the shutter unit 34d never moves in the longitudinal direction) . However, due to the movement of the 32Y toner container in the clamping direction, the shutter unit 34d moves relatively in the opening direction. That is, as shown in figure 41, the shutter unit 34d moves relatively towards the container body 33Y, thereby opening the toner outlet W. At this point, as shown in figure 41, the opening operation of the shutter unit 34d is held while the first retaining members 73dl retain the vertical surfaces 34s of the cap unit 34Y and the second retaining members 73d2, being engaged with the retaining portions 34dll of the shutter unit 34d, retain the shutter unit 34d. Therefore, the postures of the shutter unit 34d and the cap unit 34Y on the cap retainer 73 are fixed and the opening operation of the shutter unit 34d can be performed smoothly.
    On the other hand, when the 32Y toner container is removed (separated) from the toner container retainer 70 (the cap retainer 73), the operation is performed in the reverse order of the fixing operation described above. That is, the operation of the shutter closing mechanisms 73d (shutter retention mechanisms) in association with the closing operation of the shutter unit 34d is carried out in the order of figures 41, 40 and 39.
    With reference to figure 40, in the first embodiment, due to the vertical surfaces 34s that function as the retaining surfaces to be retained by the retaining members 73dl extend in the direction of attachment (in the upward direction in figure 40) (because the projections 34m are arranged), when the 32Y toner container is removed from the toner container retainer 70, a time regulator in which the shutter closing mechanisms 73d (the second retaining members 73d2) release the retainer of the shutter unit 34d (the retaining portions 34dll) using the vertical surfaces 34s as references can be delayed as compared to a time regulator in which the shutter closing mechanisms 73d completely close the shutter unit 34d. That is, because the vertical surfaces 34s (the projections 34m) are formed to extend by extending to the upper side in figure 4, when the closing operation of the shutter unit 34d is performed (relative movement of the shutter unit 34d a from the state illustrated in figure 41 to the state illustrated in figure 40), rotation of the shutter closing mechanisms 73d as illustrated in figure 39 is prevented and the shutter unit 34d closing operation can be completed while the first members of retainer 73dl are retaining the vertical surfaces 34s of the projections 34m and the second retaining members 73d2 are retaining the retaining portions 34dll of the shutter unit 34d. In other words, when the vertical surfaces 34s are not formed to extend by protruding towards the upper side in figure 40, the first retaining members 73dl release the retention of the vertical surfaces 34s in a previous time regulator and the closing mechanisms shutter 73d rotate instantly as shown in figure 39, and, consequently, the second retaining members 73d2 also release the retention of the retaining portions 34dll of the shutter unit 34d. Consequently, the shutter unit 34d cannot complete the closing operation.
    As described above, according to the first embodiment, because the projections 34m are arranged in the cap unit 34Y, it is possible to prevent the 32Y toner container from being removed from the body of the imaging apparatus 100 before the shutter unit. 34d completely close the toner outlet W. Referring to figures 34 35, the cap retainer 73 has the evacuation holes 73k formed on the wall surfaces in such a way that the projections 34m of the cap unit 34Y do not cause interference with the cover retainer wall surface 73.
    With reference to figures 42A to 42D, when the operation of fixing the toner container 32Y to the toner container retainer 70 continues, each portion of the bottle retainer 72 and the lid retainer 73 is engaged with the lid unit 34Y in sequence as described below.
    The lid unit 34Y slides over the bottle retention face 72a in the horizontal direction to be inserted into the lid retainer 73. While sliding over the bottle retention face 72a, the lid unit 34Y recedes in the horizontal direction, which can occur just before being inserted into the cap retainer 73, it is reduced by the compression member 72c and the pressure receiving member 72d. Thereafter, the first engagement portion 34e and the second engagement portions 34f of the lid unit 34Y are engaged with the engaged portion 73m of the lid retainer 73, and the side projections 34c of the lid unit 34Y are engaged with the side grooves. 73c of the cap retainer 73, so that the posture of the cap unit 34Y on the cap retainer 73 is regulated in both vertical and horizontal directions (the state shown in figure 42A proceeds to the state shown in figure 42B). Subsequently, the first hole 34a of the cap unit 34Y is engaged with the main guide pin 73a of the cap retainer 73, so that the position of the main guide is fixed (the state shown in figure 42C). Thereafter, the second hole 34b of the cap unit 34Y is engaged with the sub-tab pin 73b of the cap retainer 73, so that the positions of the main guide and the sub-tab are fixed. Before positioning is complete (until the second hole 34b engages with the sub-pin 73b star completed), the plug release tilt portion 72b releases the contact state between plugs 34d22 of the shutter unit 34d and the portions of contact 34n5 on the cover unit 34 Y. The shutter unit 34d initiates the opening operation while the postures of the shutter unit 34d and the cover unit 34Y on the cover retainer 73 are fixed by the shutter closing mechanisms 73d (the mechanisms retainer lock) (the state shown in figure 42C). In addition, until the engagement of the second hole 34b with the sub-pin 73b is completed, the sealing member 76 disposed over the circumference of the toner supply port 73w of the cap retainer 73 and the edge portion 34r (the formed on the circumference of the toner outlet W of the cover unit 34Y comes in sliding contact with each other. Consequently, the toner outlet W that is opened in the cover unit 34Y and the toner supply port 73w of the cover retainer 73 are connected with each other to complete the adjustment of the cover unit 34Y (the 32Y toner container). on the cap retainer 73 (the toner container retainer 70) (the state shown in figure 42D). At this point, the gear 33c of the container body 33Y engages with the drive gear 81 of the imaging apparatus 100, and the RFID chip 35 of the cap unit 34Y is located in a position that is optimal for performing communication. radio with antenna 73e of the imaging apparatus 100.
    Thus, according to the first embodiment, because the postures of the shutter unit 34d and the cap unit 34Y on the cap retainer 73 are fixed by the shutter closing mechanisms 73d (the shutter retaining mechanisms) in the fixing operation of the 32Y toner container, it is possible to prevent the opening operation of the shutter unit 34d from being carried out with the state in which the cover unit 34Y (the shutter unit 34d) is tilted.
    In the operation of fixing the toner container 32Y, after the first hole 34a of the cap unit 34Y is engaged with the main guide pin 7 3a of the cap retainer 73 to fix the position of the main guide, the postures of the shutter unit 34d and the cap unit 34Y on the cap retainer 73 are secured by the shutter closing mechanisms 73d (the shutter retaining mechanisms). Thereafter, the second hole 34b of the cap unit 34Y is engaged with the sub-tab pin 73b of the cap retainer 73 to secure the positions of the guide and the sub-tab. Therefore, the posture of the lid unit 34Y (the shutter unit 34d) can be corrected before the positioning of the lid unit 34Y on the sub-tab is completed.
    Before the positioning of the main guide completed by engaging the first hole 34a of the cover unit 34Y with the guide pin 7 3a of the cover retainer 73, the side projections 34c of the cover unit 34Y are engaged with the side grooves 73c of the cover retainer. cover 73, for example, to regulate the position of the cover unit 34Y on the cover retainer 73 in both vertical and horizontal directions. Therefore, cover unit 34Y can be positioned smoothly on cover retainer 73.
    After the postures of the shutter unit 34d and the cap unit 34Y on the cap retainer 73 are secured by the shutter closing mechanisms 73d (the shutter retaining mechanisms), the sealing member 76 arranged on the circumference of the supply port toner cartridge 73w and the toner outlet W (the edge portion 34r) of the cap unit 34Y slide into contact with each other, and after that the second hole 34b of the cap unit 34Y is engaged with the sub-pin 73b of the cap retainer 73, so that the positions of the main guide and the sub-guide are fixed. Therefore, the posture of the cap unit 34Y (the plug unit 34d) can be corrected without receiving sliding contact resistance from the sealing member 76.
    In the first embodiment, because the shutter closing mechanism 73d (the shutter retention mechanism) is arranged close to the sub-guide pin 73b and not close to the main guide pin 73a, the postures of the shutter unit 34d and the cover unit 34Y on the cap retainer 73 are easily corrected by the shutter closing mechanisms 73d (the shutter retaining mechanisms).
    When separating the toner container 32Y, the first hole 34a of the cover unit 34Y is kept engaged with the main guide pin 73a of the cover retainer 73 until the closing operation of the shutter unit 34d is completed after the engagement of the second hole. 34b of cover unit 34Y with the sub-tab pin 73b of cover retainer 73 being released. Therefore, it is possible to prevent the closing operation of the shutter unit 34d from being performed with the cover unit 34Y (the shutter unit 34d) being tilted.
    As described above, according to the first mode imaging device, by a single user action of moving the 32Y toner container in the longitudinal direction while holding the fastener 33d (excluding the opening / closing operation of a cover) body 110), the opening / closing operation of the toner outlet W through the shutter unit 34d is also performed and the fixing / separating operation of the 32Y toner container is completed.
    The 32Y toner container of the first embodiment is arranged so that the toner outlet W with a relatively large opening area is arranged to be oriented downwards in the vertical direction. Therefore, the toner can be effectively discharged directly from the toner outlet W by the toner weight itself.
    Fixing and separating the 32Y toner container is carried out from the front side of the toner container retainer 70 (the body of the imaging apparatus 100), and is not carried out from the upper side of the toner container retainer. 70 (the body of the imaging apparatus 100). Therefore, the flexibility in sketching the upper side of the toner container holder 70 is increased. For example, even when a scanner (a document reader unit) is placed above the toner supply devices, the operating capacity and working capacity are not impaired when fixing and separating the 32Y toner container.
    In addition, the 32Y toner container is attached to the body of the imaging apparatus 100 with the longitudinal direction of the toner container kept horizontal and therefore it is possible to increase the toner capacity of the 32Y toner container and reduce the frequency of replacing the 32Y toner container without affecting the outline of the entire body of the imaging device 100 in the height direction.
    The characteristic configuration of the 34Y toner container according to the first embodiment will be summarized with reference to figure 43. As illustrated in figure 43, the edge portion 34r (wall portion) formed over the circumference of the toner outlet W of the lid 32Y has the apex portions 34rl on both sides of the conduction and delimiter in the longitudinal direction. Each of the apex portions 34rl has a pointed shape. In addition, the edge portion 34r (especially the planes, except the parallel portions 34r2, which are in contact with the apex portions 34rl) of the lid unit 34Y is formed in a tapered tapered shape with respect to the vertical direction. With the above configuration, the plug seal 36 of the plug unit 34d and the sealing member 76 provided over the circumference of the toner supply port 73w of the cap retainer 73 smoothly comes in sliding contact with the edge portion 34r so to gradually increase (or decrease) a contact area for the edge portion 34r in association with the securing / separating operation of the 32Y toner container in the longitudinal direction. Therefore, the plug seal 36 and the sealing member 76 are less likely to be peeled or damaged.
    The shapes of the edge portion 34r and the toner outlet W are not limited to those in the first embodiment. For example, as shown in Figure 44A, the apex portions 34rl of the edge portion 34r can be formed into tapered shapes so that the amount of downward protrusions gradually decreases from the center of the toner outlet W. More specifically, the tapered portions 34r3 inclined with respect to the vertical direction can be formed on the apex portions 34rl of the edge portion 34r.
    Alternatively, as illustrated in figure 44B, the toner outlet W can be formed in a rectangular shape while the outer circumference of the rim potion 34r is formed in the hexagonal shape. In addition, the apex portions 34r4 of the edge portion 34r can be formed in tapered shapes being inclined with respect to the vertical direction. With both of the above configurations, similarly to the first embodiment, the shutter seal 36 of the shutter unit 34d and the sealing member 76 provided over the circumference of the toner supply port 73w of the cap retainer 73 smoothly comes into contact with the slide. edge portion 34r gradually increasing (or decreasing) a contact area for edge portion 34r in association with the fixing / separating operation of the 32Y toner container in the longitudinal direction. Therefore, the plug seal 36 and the sealing member 76 are less likely to be peeled or damaged.
    As described above, in the 32Y toner container, according to the first embodiment, the shutter seal 36 (shutter member) is provided on the surface of the shutter unit 34d facing the toner outlet W, and each of the vertex portions 34rl of the edge portion 34r is formed in a pointed shape so that the edge portion 34r provided over the circumference of the toner outlet W of the cap unit 34Y does not cause the plug seal 36 to be peeled or damaged . Therefore, a space to dispose of the 32Y toner container can be effectively held in the body of the imaging apparatus 100 and the toner container 32Y can be attached to the body of the imaging apparatus 100 with high adjustability and operability, so that it is possible to prevent the toner contained in the 32Y toner container from spreading outside the 32Y toner container in association with the fixing / separating operation of the 32Y toner container to the body of the imaging apparatus 100 even when the 32Y toner container is configured to discharge toner from the toner outlet W by the toner weight itself.
    The toner container described above is a toner container that is separably attached to a body of an imaging apparatus with a longitudinal direction of the toner container being kept horizontal. The toner container includes a cylindrical container body, a lid unit, and a shutter unit. The cylindrical container body has an opening at one end of it in the longitudinal direction, and is configured to transport the toner contained therein towards the opening that is inserted into the lid unit. The lid unit includes a toner outlet at a bottom portion of it to discharge toner, which has been discharged from the opening of the container body, to the outside of the toner container in a vertically downward direction. The shutter unit is retained in the bottom portion of the cover unit and moves along an outer periphery of the cover unit to thereby open and close the toner outlet. The shutter unit includes a sealing member on a surface facing the toner outlet, and the cover unit includes a downwardly protruding edge portion which is provided over the circumference of the toner outlet. The edge portion of the cover unit has tips on both sides in the longitudinal direction. Each end has a pointed shape that is pointed in the longitudinal direction so as to be separated from the center of the toner outlet.
    That is, the shutter unit 34d includes the shutter seal 36 (sealing member) on the surface to face the toner outlet W. The cover unit 34Y includes the edge portion 34r that protrudes downwards and is formed on the circumference of the toner outlet W. The edge portion 34r has the apex portions 34rl on the conductive and bounding sides in the longitudinal direction. Each of the apex portions 34rl has a pointed shape.
    In the toner container, when viewed from the bottom in the vertical direction, the edge portion of the lid unit is a hexagonal edge portion having parallel portions that are opposite each other along the longitudinal direction, and two vertex portions positioned at opposite ends of each other in the longitudinal direction.
    In the toner container, the toner outlet is formed to be hexagonal in order to follow the hexagonal shape of the edge portion when viewed from below in the vertical direction.
    In the toner container, the edges of the edge portion have tapered shapes so that the amount of downward protrusion gradually decreases according to the distance from the center of the toner outlet.
    In the toner container, the edge portion is formed so that the planes perpendicular to the longitudinal direction are tapered in shape and the amount of downward protrusion gradually decreases according to the distance from the center of the toner outlet.
    In the toner container, the sealing member is arranged to protrude in the longitudinal direction from the end of the shutter unit in the closing direction.
    In the toner container, the cover unit includes a cylindrical cavity formed inside it to extend in the longitudinal direction and a toner drop path that has a columnar shape with a constant flow passage area from a lower circumferential surface of the cylindrical cavity for the toner outlet.
    In the toner container, the container body includes a spiral projection formed on the circumferential surface thereof and is retained to be rotatable with respect to the lid unit.

    In this way, the sealing member is provided on the surface of the shutter unit facing the toner outlet, and the edges of the edge portion have tapered shapes so that the edge portion provided on the circumference of the toner outlet does not the sealing member to be peeled or damaged. Consequently, a toner container and an imaging device can be provided so that the toner contained in the toner container is less likely to spread outside the toner container in the fixing / separating operation of the toner container to / from the body of the imaging device.
    As described above, in the 32Y toner container according to the first embodiment, due to the vertical surfaces 34s, on which the shutter tracks 34t directing the closing / opening operation of the shutter unit 34 are formed, extending from from the end of the shutter unit 34d, which is in a closed position of the toner outlet W in the closing direction, to the protruding position in the longitudinal direction, a time regulator in which the shutter closing mechanisms 73 arranged in the body of the image forming apparatus 100 release the retention of the shutter unit 34d using the vertical surfaces 34s as references can be delayed as compared to the time regulator in which the shutter closing mechanisms 73d completely close the shutter unit 34d. Therefore, a space to dispose of the 32Y toner container can be effectively held in the body of the imaging apparatus 100 and the toner container 32Y can be attached to the body of the imaging apparatus 100 with high adjustability and operability, so that it is possible to avoid the problems caused by the spreading of the toner contained in the toner container 32Y from the outside of the toner container 32Y in the operation of separating the toner container 32Y from the body of the imaging apparatus 100 even when the 32Y toner container is configured to discharge toner from the toner outlet W by the toner weight itself.
    In a conventional toner container, when a flow-through area of a toner transport path or an opening area for a toner outlet is enlarged, it is possible to configure a shutter unit so that the shutter unit can slide to open and close the toner outlet in association with the fixing / separating operation of the toner container to / from the body of an imaging apparatus, so that the fixing / separating operation of the toner container to / from the machine body is performed by a single action when a longitudinal direction of the toner container is fixed as a fixation / separation direction. In this case, however, it is necessary to configure the shutter unit by closing the toner outlet so that it does not move easily so that the toner contained in the toner container that is isolated from, and not disposed of in, the body of the training apparatus image does not leak toner out of the toner container.
    The toner container described above is a toner container that is attached separately to the body of an imaging device with a longitudinal direction of the toner container kept horizontal, and includes: a cylindrical container body that has an opening at one end of the same in the longitudinal direction, and is configured to transport the toner contained therein in the direction of the opening; a lid unit into which the container body opening is inserted, and which includes a toner outlet in a bottom portion to discharge the toner, which was discharged from the container body opening, outside the container toner in a downward direction; and a shutter unit which is retained in the bottom portion of the cover unit, and moves along an outer periphery of the cover unit to thereby open and close the toner outlet. The shutter unit includes: a main shutter unit is engaged with the rail unit arranged in the cover unit, and moves along the rail unit to thereby open and close the toner outlet; and a deformable plug member which is integrally formed in the main plug unit, and is elastically deformable in a vertical direction using a connection position between the deformable plug member and the main plug unit as a base point. The deformable plug member includes a plug that contacts a contact portion formed in the lid unit to thereby regulate the movement of the plug unit in one direction to open the closed toner outlet; and a tampon release unit which protrudes downwards in the vertical direction, and moves the tampon upwards along with the elastic deformation upwards of the deformable plug member when receiving an external force from below to thereby release a state of contact between the plug and the contact portion.
    More specifically, the obturator unit 34d includes the deformable obturator member 34d2 which is formed to be elastically deformable using a connection position, as a base point, between the deformable obturator member 34d2 and the moving obturator main unit 34dl along the cover unit 34 Y rail unit to close and open the toner outlet. The deformable plug member 34d2 includes plugs 34d22 that regulate movement of the plug unit 34d in one direction to open the toner outlet that was closed, and the plug release unit 34d21 which releases a contact state between plugs 34d22 and the 34n5 contact portions receiving an external force from below.
    In the toner container described above, the plug deformation unit is arranged on the side of the container body in the longitudinal direction with respect to the main plug unit, the plug is formed on the tip, which is outside the main plug unit, of the deformable plug member, and the plug release unit is formed between the plug and the connection position.
    In the toner container described above, the cover unit includes a housing unit that maintains a deformed state of the deformable plug member when the shutter unit opens the toner outlet and houses the deformable plug member.
    In the toner container described above, the main shutter unit further includes a second plug that contacts a second contact portion formed on the cover unit and regulates a movement of the shutter unit in a direction opposite to a direction in which the buffer performs the adjustment.
    In the toner container described above, the lid unit includes a cylindrical cavity formed within it to extend in the longitudinal direction and a toner drop path that is columnar in shape with a constant flow passage area from a lower circumferential surface of the cylindrical cavity at the toner outlet.
    In the toner container described above, the container body includes a spiral-shaped projection formed on the inner circumferential surface thereof and is retained to be rotatable with respect to the lid unit.
    The toner container is disposed on the body of the image machine. Thus, according to the configuration, the obturator unit includes the deformable obturator member that is deformed elastically using the connection position between the main obturator unit and the deformable obturator member as a base point, and the obturator member. deformable includes the plug that regulates a movement of the plug unit in the opening direction and the plug release unit that releases the plug. Consequently, a toner container and an imaging apparatus can be provided in which the shutter unit that opens and closes the toner outlet is not easily moved when the toner container is isolated from the imaging apparatus.
    As described above, the 32Y toner container of the first embodiment includes, in the shutter unit 34d, the deformable shutter member 34d2 which is elastically deformable using the connection position of the main shutter unit 34dl as a base point, and also includes, on the deformable plug member 34d2, the plugs 34d22 to regulate the movement of the plug unit 34d in the opening direction and the plug release unit 34d21 to release the adjustment.

Second Mode
    A second embodiment will be described in detail below with reference to figures 45 to 52. A toner container according to the second embodiment is different from the first embodiment in which the stirring member 33f is differently regulated.
    Referring to figure 45, the 32Y toner container of the second embodiment mainly includes, similarly to the first embodiment, the 33Y container body (bottle body) and the cap unit 34Y (bottle cover) arranged in the head portion of the body container. The toner container 32Y of the second embodiment further includes, in addition to the container body 33Y and the cap unit 34Y, the stirring member 33f, the cap seal 37, the plug unit 34d, the plug seal 36 as a member sealing, and the RFID 35 chip as an electronic information storage member.
    Referring to figures 45 and 46, in the 32Y toner container of the second embodiment, similarly to the first embodiment, the stirring member 33f that rotates with the 32Y toner container is fitted to the bottle opening 33a (the opening A).
    The stirring member 33f is formed of a pair of plate members extending from cavity B in the lid unit 34Y into the container body 33Y (see also figure 50). The stirring member 33f differs from that of the first embodiment in that the plate members in the pair are alternately inclined in the second embodiment. The stirring member 33f is configured so that the tip of it reaches the upper side of the toner outlet W in the cover unit 34 Y and the other end of it (the end on the opposite side) reaches the flow portion (a portion surrounded by a dashed circle in figures 45 and 46) when the lid unit 34Y and the container body 33Y are assembled together. The rotation of the stirring member 33f together with the rotation of the opening A of the container body 33Y improves the toner discharge performance from the opening A. In particular, the stirring member 33f according to the second embodiment improves the capacity of toner agitation in the front and rear positions of opening A because the pair of plate members are alternately tilted.
    With reference to figures 45 and 46, the engaging members (convex portions), which are engaged with the claw members 34j (see figure 50) of the lid unit 34Y in order to connect the container body 33Y with the lid unit 34Y, are formed around an outer circumference of the bottle opening 33a of the container body 33Y. As described above, the container body 33Y (which has the integrally formed gear 33c) is engaged with the lid unit 34Y so as to be relatively pivoting against the lid unit 34Y.
    The inside diameter of a head portion of the container body 33Y (near the position where the gear 33c is formed) is less than the inside diameter of a container portion containing toner (the position where the spiral projection 33b is formed) (see figure 50). The flow portion (the portion surrounded by the dashed circle in figures 45 and 46), from which the inner circumferential surface protrudes inward, is provided in the head portion of the container body 33Y. The toner transported in the direction of opening A by the spiral projection 33b in association with the rotation of the container body 33Y is poured, by the flow portion (the portion surrounded by the dashed circle in figures 45 and 46), in a portion of small diameter of the head portion. The toner poured into the small diameter portion of the head portion is agitated by the stirring member 33f, and is discharged into cavity B of the cap unit 34Y through opening A.
    With reference to figures 47 to 50, the shutter unit 34d, the shutter seal 36, the cap seal 37 (sealing member), and the RFID chip 35 (electronic information storage member) are arranged in the sizing unit. cap 34Y of the 32Y toner container.
    The lid unit 34Y includes the insert portion 34x with an inner diameter larger than the inner diameter of cavity B (see figure 49), and the opening A of the container body 33Y is inserted into the insert portion 34x. With reference to figures 48 and 52, the toner outlet W is formed in the bottom portion of the cap unit 34Y to allow the toner that has been discharged from opening A of the container body 33Y to be discharged outside the container toner in a vertically downward direction (falls by its own weight). The shutter unit 34d for opening and closing the toner outlet W is held in a slidable mode in the bottom portion of the cap unit 34Y. More specifically, the shutter unit 34d moves relatively in the longitudinal direction from the side of the cap unit 34Y to the side of the container body 33Y (leftward movement in figure 50) to open the toner outlet W. In addition In addition, the shutter unit 34d moves relatively in the longitudinal direction from the side of the container body 33Y to the side of the lid unit 34Y (movement to the right in figure 50) to close the toner outlet W. Operation opening / closing of the 34d shutter unit (the opening / closing operation of the toner outlet W) is carried out in conjunction with the fixing / separating operation of the 32Y toner container on the toner container retainer 70 (the machine body image formation 100) on long. Figures 51 and 52 illustrate the operation of the shutter unit 34d from the beginning to complete opening the toner outlet W.
    With reference to figures 47 and 48, the first hole 34a (main guide hole) is formed over the upper portion (ceiling portion) of the cap unit 34Y so that the first hole 34a extends in the longitudinal direction from the face end of the cap unit 34Y which is perpendicular to the longitudinal direction. The first hole 34a acts as a main guide for positioning the cover unit 34Y in the body of the imaging apparatus 100. More specifically, the first hole 34a of the cover unit 34Y is engaged with the main guide pin 72a of the image retainer. cover 73 in association with the operation of fixing the toner container 32Y to the toner container retainer 70 in the longitudinal direction.
    The second orifice 34b (sub-orifice) is formed in the lower portion (bottom portion) of the cap unit 34Y so that the second orifice 34b extends in the longitudinal direction from the end face of the cap unit 34Y which is perpendicular to the longitudinal direction in order not to reach the position of the toner outlet W. The second hole 34b acts as a sub-guide for positioning the cover unit 34Y on the body of the imaging apparatus 100. More specifically, the second hole 34b of the cover unit 34Y is engaged with the sub-tab pin 73b of cover retainer 73 in association with the operation of securing the 32Y toner container to the toner container retainer 70 in the longitudinal direction. Using the two holes 34a and 34b so configured, the position of the cap unit 34Y is fixed on the toner container retainer 70.
    With reference to figures 47 and 48, the plug portions 34g are formed on the outer circumference of a portion where the insertion portion 34z is formed and on both sides of the upper portion of the lid unit 34Y. Each plug portion 34g has a flat top face and a flat side face that are approximately perpendicular to each other.
    When the 32Y toner container is attached to the toner container retainer 70, the plug portions 34g come into contact with the positioning members (not shown), which are arranged in the cap retainer 73 of the toner container retainer 70, in association with the fastening operation. Consequently, the recoil of the lid unit 34 Y on the lid retainer 73 can be suppressed, so that the lid unit 34 Y can be smoothly attached to the lid retainer 73.
    With reference to figures 47 and 48, the side projections 34c (compressed portions) are arranged on both side sides of the lid unit 34Y and protrude from the outer circumference surface of the lid unit 34Y. The side projections 34c according to the second embodiment are compressed in one direction against a force in the clamping direction (or the separation operation) by the compression portions (not shown) of the cap retainer 73 when the cap unit 34Y is attached a (or separated from) of the cap retainer 73 of the toner container retainer 70 (the body of the imaging apparatus 100). Therefore, during the clamping operation (or detaching operation) of the 32Y toner container to the cap retainer 73, after a user feels the force against an operating force in the clamping direction (or clamping direction) in the position where the projections 34c are engaged with the compression portions, the user increases the operating force in the clamping direction (or in the separation direction) to complete the clamping operation (or the separation operation) instantly. Thus, the user gets a good feeling of clicking on the fixing operation (or the separation operation) of the 32Y toner container to the cap retainer 73.
    More specifically, as illustrated in figures 47 and 48, the lateral projections 34c according to the second embodiment are formed in the form of grooves along the longitudinal direction (direction of attachment). The groove shapes of the side projections 34c are formed so that the slopes on the tip side become smoother than the slopes on the side of the container body. Therefore, the user can smoothly perform the fixing / separating operation with a good click feeling when performing the fixing / separating operation from the 32Y toner container to the cap retainer 73.
    With reference to figures 47 and 48, the convex portions 34g and 34h to ensure the incompatibility of the 32Y toner container with the toner containers of other colors are formed on the surface of the outer circumference of the lid unit 34Y. The convex portions 34g and 34h are configured to engage with the engagement portions 73c of the cap retainer 73 when the operation of fixing the toner container 32Y to the toner container retainer 70 is performed correctly (when the toner container 32Y is fixed to a correct position on the toner container holder 70). With the above configuration, it is possible to prevent a toner container for a certain color (for example, a toner container for yellow) from being attached to a toner container retainer for a different color (for example, a toner to cyan), thereby preventing a failure to form a desired color image. That is, it is possible to prevent the container from being attached incorrectly to the toner container retainer.
    Referring to Figure 48, the convex portions 34g (portions in the form of incompatibility) are two projections that are formed radially at the upper portion of the tip of the cap unit 34Y. Each of the two projections (the 34g mismatch portions) includes a 34gl base portion and two incompatible claw members projecting from the 34gl base portion. The base portion 34gl has a trapezoidal shape that spreads outwards. The two incompatible claw members 34g2 are arranged so that they protrude radially outward (from the top face of the base portion 34gl.
    The 34g2 incompatible claw members are cut depending on the type (color) of toner contained in the toner container in order to fulfill the incompatible function for each color. That is, some of the incompatible claw members 34g2 are cutter with a cutting tool, such as a tongs or a cutter, from the cover unit 34Y having the four incompatible claw members 34g2 in total on the left and right sides, so that portions in the form of mismatch 34g in various ways can be formed. With the above configuration, it becomes unnecessary to manufacture the same number of molds as the number of types of toner containers (lid units), and it becomes possible to form a plurality of incompatible lid unit types using a mold to enable reduce a total manufacturing cost to produce a plurality of types of toner containers.
    With reference to figure 48, a relatively large space is fixed between the two incompatible claw members 34g2 in the incompatibly formed portions 34g so that the incompatible claw members 34g2 can be easily cut using a cutting tool such as tongs or a cutter.
    With reference to figure 48 and other related drawings such as figures 49 to 52, the lid unit 34Y of the second embodiment includes an incompatible convex portion 34h to identify a destination of the toner container (for example, for domestic use or for export to the US, Europe, and other countries and regions). The convex portion 34h is configured to be engaged with an engaging member (not shown) formed on the bottle retainer 72 when the body of the imaging apparatus 100 as an adjustment object is compatible (when the cap unit is attached to the correct body by the image formation apparatus 100).
    In the 32Y toner container according to the second embodiment, similarly to the first embodiment, the shutter seal 36 (sealing member) is provided on the surface of the shutter unit 34d facing the toner outlet W, and the portions vertex 34rl of the edge portion 34r are formed into the pointed shapes so that the edge portion 34r provided in the circumference of the toner outlet W of the cover unit 34Y does not cause the plug seal 36 to be peeled or damaged.
    Therefore, also in the second embodiment, similarly to the first embodiment, a space for disposing the 32Y toner container can be effectively secured in the body of the imaging apparatus 100 and the 32Y toner container can be attached to the body of the imaging apparatus image 100 with high adjustability and operability, so that it is possible to prevent the toner contained in the 32Y toner container from spreading outside the 32Y toner container in association with the fixing / separating operation of the 32Y toner container to / from the body of the imaging apparatus 100 even when the 32Y toner container is configured to discharge toner from the toner outlet W by the toner weight itself.
    Also, in the 32Y toner container according to the second embodiment, similarly to the first embodiment, because the vertical surfaces 34s, on which the shutter rails 34t directing the opening / closing operation of the shutter unit 34d are formed, extend from the end of the shutter unit 34d, which is in a position to close the toner outlet W in the closing direction, to the projecting position in the longitudinal direction, a time regulator in which the shutter closing mechanisms 73d arranged in the the body of the imaging apparatus 100 releases the retention of the shutter unit 34d using the vertical surfaces 34s as a reference can be delayed compared to a time regulator in which the shutter closing mechanisms 73d completely close the shutter unit 34d.
    Therefore, also in the second embodiment, similarly to the first embodiment, a space to dispose of the 32Y toner container can be effectively secured in the body of the imaging apparatus 100 and the 32Y toner container can be attached to the body of the imaging apparatus image 100 with high capacity and adjustment operability, so that it is possible to prevent the toner contained in the 32Y toner container from spreading outside the 32Y toner container in association with the operation of separating the 32Y toner container from the image apparatus body 100 even when the 32Y toner container is configured to discharge toner from the toner outlet W by the toner weight itself.
    Also in the 32Y toner container of the second embodiment, similarly to the first embodiment, the shutter unit 34d includes the deformable shutter member 34d2 which is elastically deformed using the connection position of the main shutter unit 34dl as a base point, and also includes , on the deformable plug member 34d2 the plugs 34d22 to regulate the movement of the plug unit 34d in the opening direction and the plug release unit 34d21 to release the regulation.
    Therefore, also in the second embodiment, similarly to the first embodiment, a space for disposing the 32Y toner container can be effectively secured in the body of the imaging apparatus 100 and the 32Y toner container can be attached to the body of the imaging apparatus image 100 with high capacity and adjustment operability, so that it is possible to prevent the shutter unit 34d which opens and closes the toner outlet W from being easily moved when the 32Y toner container remains isolated even when the 32Y toner container is configured to discharge toner from the toner outlet W by the toner weight itself. Third Mode
    A third embodiment will be described in detail below with reference to figures 53 to 56. A toner container according to the third embodiment is different from the second embodiment in which the stirring member 33f is differently configured.
    The 32Y toner container of the third embodiment mainly includes, similarly to the second embodiment, the container body 33Y (bottle body) and the lid unit 34Y (bottle lid) arranged on the head portion of the container body. The third mode 32Y toner container further includes, in addition to the container body 33Y and the cap unit 34Y, the shaking member 33f, the cap seal 37, the plug unit 34d, the plug seal 36 as a member seal, and the RFID 35 chip as an electronic information storage member (see figure 45).
    In the toner container 32Y of the third embodiment, similarly to the second embodiment, the stirring member 33f which rotates in association with the container body 33Y is fitted to the bottle opening 33a, (the opening A). Specifically, with reference to figures 53 to 55, an adjustment portion 33f2 of the stirring member 33f is adjusted by pressing against the bottle opening 33a (opening A) illustrated in figure 45.
    As illustrated in figures 53 to 55, the stirring member 33f of the third embodiment includes plate members 33fl being a pair, extending from the cavity 8 in the lid unit 34Y towards the interior of the container body 33Y. The plate members 33fl of the stirring member 33f are alternately adjusted, similarly to the second embodiment. The stirring member 33f is configured so that the tip thereof (on the side where the closing plates on the lid unit 34Y and the other end (the end on the opposite side) reaches the flow portion (the portion surrounded by the dashed circle in figures 45 and 46) when the lid unit 34Y and the container body 33Y are assembled together. together with the rotation of opening A of the container body 33Y improves the toner discharge performance from opening A,
    As shown in figures 53 to 55, the stirring member 33f of the third embodiment is different from the second embodiment in which the feed plates 33fl0 are arranged on the tips of the plate members 33fl (on the side towards the inside of the cover unit 34Y) . Lead plates 33fl0 are plate members that remain approximately perpendicular to the main bodies of plate members 33fl. Each of the plates 33fl0 includes a tapered portion 33 × 100 on the outer circumference of the plates.
    As described above, because the feed plates 33fl0 are arranged on the tips of the plate members 33fl of the stirring member 33f, the feed plates 33fl0 push the toner towards the toner outlet W in the cover unit 34Y in association with the rotation of the stirring member 33f. Therefore, even when the 34Y cover unit is clogged with toner in the vicinity or at the toner outlet W (the toner drop path C), the toner can be smoothly discharged from the W toner outlet.
    Figures 56A to 56D are schematic front views of how the stirring member 33g rotates in the toner container 32Y which has the stirring member 33f with the advance plates 33fl0 (the stirring member 33f of the third embodiment). On the other hand, figures 57A to 57-D are schematic front views of how the stirring member 33f rotates in the toner container 32Y that has the stirring member 33f without the lead plates 33fl0 (the stirring member 33f of the second embodiment) ).
    In figures 56A to 56D, the black arrows indicate a toner transport direction in which the stirring member 33f transports the toner in the direction of the toner outlet W (the toner supply port 73W.)
    As illustrated in Figure 57A, when plates 33fl0 are not arranged at the tips of plate members 33f of stirring member 33f, lead plates 33fl0 transport the toner in a circumferential direction along the inner circumference of the cover unit 34Y in association with the rotation of the stirring member 33f. In contrast, as illustrated in figure 56A, when the feed plates 33fl0 are arranged on the tips of the plate members 33fl of the stirring member 33f, the feed plates 33fl0 transport the toner in the direction of the toner outlet W (transport in one direction approximately normal with respect to the internal circumference of the lid unit 34Y) in association with the rotation of the stirring member 33f.
    In the 32Y toner container according to the third embodiment, similarly to each of the above described embodiments, the shutter seal 36 (sealing member) is provided on the surface of the shutter unit 34d to face the toner outlet W , and the vertex portions 34rl of the edge portion 34r are formed into the pointed shapes so that the edge portion 34r provided over the circumference of the toner outlet W of the cap unit 34Y does not cause the shutter seal 36 to be peeled off or broken.
    Therefore, also in the third embodiment, similarly to each of the modalities described above, a space for arranging the 32Y toner container can be effectively secured in the body of the imaging apparatus 100 and the 32Y toner container can be fixed to the body of the image formation apparatus 100 with high capacity and adjustment operability, so that it is possible to prevent the toner contained in the 32Y toner container from spreading outside the 32Y toner container in association with the fixing / separating operation of the container of toner 32Y to the body of the imaging apparatus 100 even when the 32Y toner container is configured to discharge toner from the toner outlet W by the weight of the toner itself. Fourth Mode
    The fourth modality will be described in detail below with reference to figures 58 ,. 59 and 60A to 60C. A toner container according to the fourth embodiment is different from the third embodiment in which a flexible member 34u is disposed near the toner outlet W of the cap unit 34Y.
    The fourth embodiment 32Y toner container mainly includes, similarly to the third embodiment, the container body 33Y (bottle body) and the lid unit 34Y (bottle cap) arranged on the head portion of the container body. The fourth mode toner container 32Y further includes, in addition to the container body 33Y and the cap unit 34Y, the stirring member 33f, the cap seal 37, the plug unit 34dm the plug seal 36 as a member of seal, and the RFID 35 chip as an electronic information storage member (see figure 45).
    In the fourth embodiment 32Y toner container, similarly to the third embodiment, the stirring member 33f which rotates together with the container body 33Y is fitted to the bottle opening 33A (the opening A).
    As shown in Figure 58, the stirring member 33f of the fourth embodiment includes the plate members 33fl being a pair, extending from cavity B in the lid unit 34Y towards the interior of the container body container 33Y (which are alternately inclined). The stirring member 33f of the fourth embodiment further includes the lead plates 3310 on the tips of the plate members 33fl (on the side towards the interior of the lid unit 34Y), similarly to the third embodiment.
    Referring to Figures 58, 59 and 60a to 60G, the lid unit 34Y of the fourth embodiment is different from the third embodiment, in which the lid unit 34Y includes a flexible member 34u made of flexible material such as mylar with a thickness of about 0.188 mm to 0.5 mm extending from the toner drop path C to cavity B. More specifically, as shown in figure 59, a part of flexible member 34u is curved, and a fixing portion 34u2 (with a width greater than a flexible portion 34ul) as a clamping surface is attached (clamped) to the inner wall of the toner drop path C (the inner wall on the side next to the toner outlet W and on the downstream side of the stirring member 33f in the rotational direction). Specifically, the attachment portion 34u2 is attached to the inner wall of the toner drop path C so that the curved portion of the flexible member 34u can be located in the toner drop path C. The flexible portion 34ul of the flexible member 34u is a free end and extends from the toner drop path C into cavity B. The tip of the flexible portion 34ul comes into contact with the advance plates 33fl0 in association with the rotation of the stirring member 33f, so that even when the 34Y cap unit is clogged with toner in the vicinity of the toner outlet W (the toner drop path C) is clogged with toner, the toner can be smoothly discharged from the toner outlet W.
    More specifically, as illustrated in figures 60A to 60D, the feed plates 33fl0 push the flexible member 34u (the flexible portion 34ul) in association with the rotation of the stirring member 33f, so that the flexible member 34u is gradually bent in one arcuate shape. At this time, even when the portion between the inner wall of the toner drop path C and the flexible member 34u is clogged with toner with the stirring member 33f being in the state illustrated in figure 60D, because the flexible member 34u is greatly curved in an arcuate shape and the space between the inner wall of the toner drop path C and the flexible member 34u increases as illustrated in figure 59 (D), the toner clogging the toner drop path C is loosened.
    Thereafter, as shown in figure 60E, a flatter portion of the lead plate 33fl0 and a flatter portion of flexible member 34u overlap each other, and flexible member 34u is deformed to become almost flat with the fixing portion 34u2 in the flexible portion 34ul. During this deformation, the space between the flexible member 34u and the toner becomes large to promote the toner to loosen and the toner is still supplied to the space by being pushed by the advance plate 33fl0 (the state shown in figure 58). Consequently, toner discharge efficiency and toner drop performance at toner outlet W (the toner drop path C) are promoted. Thereafter, as illustrated in figure 60F, flexible member 34u becomes fully engaged, and contact between flexible member 34u and lead plate 33fl0 is released. Then, as illustrated in figure 60G, the flexible member 34u returns to the initial state by the elastic force of the flexible member 34u. At this point, the toner receives a restoring force caused by the elasticity of the flexible member 34u, so that the release of the toner and the discharge of the toner in the way of falling toner C are promoted.
    The shape of the flexible member 34u is not limited to that described in the fourth embodiment. For example, flexible member 34u may not have a curved portion, or it may have a fixation portion 34u2 in a different shape.
    In the 32Y toner container according to the fourth embodiment, similarly to each of the aforementioned embodiments, the shutter seal 36 (sealing member) is provided on the surface of the shutter unit 34d so that it faces the outlet of toner W, and the vertex portions 34rl of the edge portion 34r are formed in pointed shapes so that the edge portion 34r provided in the circumference of the toner outlet W of the cap unit 34Y does not cause the shutter seal 36 to be peeled or damaged.
    Therefore, also in the fourth modality, similar to each of the modalities described above, a space to dispose of the toner container 32Y can be effectively secured in the body of the image forming apparatus 100 and the toner container 32Y can be fixed to the body of the image formation apparatus 100 with high capacity and adjustment operability, so that it is possible to prevent the toner contained in the 32Y toner container from spreading outside the 32Y toner container in association with the fixing / separating operation of the container of toner 32Y to the body of the imaging apparatus 100 even when the 32Y toner container is configured to discharge toner from the toner outlet W by the toner weight itself.
    In the above modes, only toner is contained in the 32Y, 32M, 32C and 32K toner containers. However, it is possible to contain two-component developer in the 32Y, 32M, 32C and 32K toner containers for an image forming device that appropriately supplies two-toner-formed developer and transport to a developer device. Even for this case, the same advantages as described above can be obtained.
    In the above embodiments, part or all of the 6Y, 6M, 6C and 6K image forming units can be configured as process cartridges. Even for this case, the same advantages as described above can be obtained.
    In the above embodiments, the container body 33Y is rotatable so that the toner contained in the container body 33Y can be transported in the direction of opening A. However, the container body 33Y can be configured so that the container body 33Y is retained in a non-rotating manner by the toner container holder 70 together with the lid unit 34Y, and the container body 33Y includes, inside, a transport member (for example, a transport member that has a transport coil or a plurality of transport blades on a shaft portion and rotating in a direction predetermined by a gear separate from the container body) to transport in the direction of opening A so that the toner contained in the container body 33Y can be transported in the direction of opening A (see figure 61).
    More specifically, as illustrated in figure 61, the 32Y toner container mainly includes the 33Y toner container, a gear 44y and the cap unit 34Y (bottle cap). Opening A is arranged on the head portion of the container body 33Y, and gear 44Y is pivotally arranged on the outer circumference of opening A. Gear 44Y engages with the drive gear of the body of the forming machine image 100 to rotate a 4 6Y coil about an axis of rotation. Opening A is used to discharge the toner contained in the container body 33Y into the space inside the lid unit 34 Y. A rotating shaft 45Y is integrally arranged on gear 44Y, and the coil in the form of a spiral 4 6Y (coil transport) is connected to the 45Y rotary axis. One end of the rotary shaft 45Y is supported by a bearing 34Ya of the cover unit 34Y. Coil 46Y is extended from opening A to the bottom portion within container body 33Y. The gear 44Y rotates around the container body 33Y to thereby rotate the rotary axis 45Y and the coil 46Y. Therefore, the toner contained in the container body 33Y is transported to the opening side A by a toner transporting force from the 46Y coil. The gear 44Y is inserted into the outer circumference of the opening A so as to be interspersed by the container body 33Y and the lid unit 34 Y. A rubber member 47Y is disposed between the gear 44Y and the container body 33Y on the side of a of the 44Y gear faces. A sealing member 48Y is disposed between gear 44Y and cover unit 34Y on the other side of gear 44Y. With this configuration, the sealing capacity of the entire 32Y toner container is ensured. That is, it is possible to prevent the toner from leaking through a gap between any pairs of gear 44Y, the container body 33Y, and the cap unit 34Y.
    The present invention can also be applied to the above 32Y toner container similarly to the above embodiments. Consequently, it is possible to obtain the same advantages as the above modalities.
    In the above modalities, in each of the 60Y, 60N, 60C and 60K toner supply devices, the toner transport path formed with the toner tank (61Y), the toner conveyor (62Y, 63Y), and the toner drop shipping (64Y) has an inverted N character shape (similar to the shape of the Russian letter M) as illustrated in figure 1 (a shape of the character N when viewed from the back side of figure 1). The toner carrier (62Y, 63Y) for each color is provided on the top side of the process cartridge (the 6Y imaging unit) for the corresponding color, and an upper side of the opening for fixing and separating the process cartridge to the image machine body 100. The toner container (32Y), the toner tank (61Y) and the upstream side of the toner carrier (62Y) for each color are provided on the top side of the nearby process cartridge ( the left neighbor in figure 1), not the process cartridge for the corresponding color. With the above configuration, in a tandem-type imaging device in which a plurality of process cartridges (imaging units) are arranged in parallel, a process cartridge (imaging unit) does not cause interference with the toner supply device when fixing or separating the process cartridge is performed. In addition, it is possible to provide an image forming apparatus in which the outline of the toner containers and process cartridges for the respective colors in the vertical direction can be obtained in a compact way without varying the quantity of a toner supply.
    It is understood that the present invention is not limited to the modalities described above, and the modalities can be readily modified within the range of technical concepts of the present invention. The number, positions, forms of elements are not limited to those in the modalities. The number, positions, forms of elements appropriate to embody the present invention can be used.
