Embodiment 1 FIG.
The first embodiment of the present invention will be described in detail with reference to FIGS.
First, the configuration and operation of the entire image forming apparatus will be described.
As shown in FIG. 1, in a toner container housing portion 70 above the image forming apparatus main body 100, toner containers 32Y, 32M as four detachable devices corresponding to each color (yellow, magenta, cyan, black) are provided. 32C and 32K (developer containers) are detachably (replaceable) installed (see also FIGS. 3 to 5).
An intermediate transfer unit 15 is disposed below the toner container housing portion 70. Image forming portions 6Y, 6M, 6C, and 6K corresponding to the respective colors (yellow, magenta, cyan, and black) are arranged in parallel so as to face the intermediate transfer belt 8 of the intermediate transfer unit 15.
Below the toner containers 32Y, 32M, 32C, and 32K as detachable devices (developer containers), toner replenishing devices 60Y, 60M, 60C, and 60K are disposed, respectively. The toners stored in the toner containers 32Y, 32M, 32C, and 32K are supplied (supplemented) into the developing devices of the image forming units 6Y, 6M, 6C, and 6K by the toner replenishing devices 60Y, 60M, 60C, and 60K, respectively. )

  Referring to FIG. 2, an image forming unit 6Y corresponding to yellow includes a photosensitive drum 1Y, a charging unit 4Y disposed around the photosensitive drum 1Y, a developing device 5Y (developing unit), a cleaning unit 2Y, It is comprised by the static elimination part (not shown) etc. Then, an image forming process (charging process, exposure process, developing process, transfer process, cleaning process) is performed on the photosensitive drum 1Y, and a yellow image is formed on the photosensitive drum 1Y.

  The other three image forming units 6M, 6C, and 6K have substantially the same configuration as that of the image forming unit 6Y corresponding to yellow except that the color of the toner used is different. A corresponding image is formed. Hereinafter, description of the other three image forming units 6M, 6C, and 6K will be omitted as appropriate, and only the image forming unit 6Y corresponding to yellow will be described.

Referring to FIG. 2, the photosensitive drum 1Y is driven to rotate clockwise in FIG. 2 by a drive motor (not shown). Then, the surface of the photosensitive drum 1Y is uniformly charged at the position of the charging unit 4Y (a charging process).
After that, the surface of the photosensitive drum 1Y reaches the irradiation position of the laser beam L emitted from the exposure device 7 (see FIG. 1), and the electrostatic latent image corresponding to yellow by exposure scanning at this position. Is formed (this is an exposure step).

Thereafter, the surface of the photosensitive drum 1Y reaches a position facing the developing device 5Y, and the electrostatic latent image is developed at this position to form a yellow toner image (developing process).
Thereafter, the surface of the photosensitive drum 1Y reaches a position facing the intermediate transfer belt 8 and the first transfer bias roller 9Y, and the toner image on the photosensitive drum 1Y is transferred onto the intermediate transfer belt 8 at this position. (This is a primary transfer step.) At this time, a small amount of untransferred toner remains on the photosensitive drum 1Y.

Thereafter, the surface of the photosensitive drum 1Y reaches a position facing the cleaning unit 2Y, and untransferred toner remaining on the photosensitive drum 1Y at this position is mechanically collected by the cleaning blade 2a (in the cleaning process). is there.).
Finally, the surface of the photosensitive drum 1Y reaches a position facing a neutralization unit (not shown), and the residual potential on the photosensitive drum 1Y is removed at this position.
Thus, a series of image forming processes performed on the photosensitive drum 1Y is completed.

The image forming process described above is performed in the other image forming units 6M, 6C, and 6K in the same manner as the yellow image forming unit 6Y. That is, the laser beam L based on the image information is emitted from the exposure unit 7 disposed below the image forming unit onto the photosensitive drums of the image forming units 6M, 6C, and 6K. Specifically, the exposure unit 7 emits a laser beam L from a light source, and irradiates the photosensitive drum through a plurality of optical elements while scanning the laser beam L with a polygon mirror that is rotationally driven.
Thereafter, the toner images of the respective colors formed on the respective photosensitive drums through the development process are transferred onto the intermediate transfer belt 8 in an overlapping manner. In this way, a color image is formed on the intermediate transfer belt 8.

  Here, referring to FIG. 1, the intermediate transfer unit 15 includes an intermediate transfer belt 8, four primary transfer bias rollers 9Y, 9M, 9C, 9K, a secondary transfer backup roller 12, a plurality of tension rollers, and an intermediate transfer. It consists of a cleaning unit, etc. The intermediate transfer belt 8 is stretched and supported by a plurality of roller members, and is endlessly moved in the direction of the arrow in FIG.

The four primary transfer bias rollers 9Y, 9M, 9C, and 9K respectively sandwich the intermediate transfer belt 8 with the photosensitive drums 1Y, 1M, 1C, and 1K to form a primary transfer nip. Then, a transfer bias reverse to the polarity of the toner is applied to the primary transfer bias rollers 9Y, 9M, 9C, and 9K.
The intermediate transfer belt 8 travels in the direction of the arrow and sequentially passes through the primary transfer nips of the primary transfer bias rollers 9Y, 9M, 9C, and 9K. In this way, the toner images of the respective colors on the photosensitive drums 1Y, 1M, 1C, and 1K are primarily transferred while being superimposed on the intermediate transfer belt 8.

  Thereafter, the intermediate transfer belt 8 on which the toner images of the respective colors are transferred in a superimposed manner reaches a position facing the secondary transfer roller 19. At this position, the secondary transfer backup roller 12 sandwiches the intermediate transfer belt 8 with the secondary transfer roller 19 to form a secondary transfer nip. The four-color toner images formed on the intermediate transfer belt 8 are transferred onto a recording medium P such as transfer paper conveyed to the position of the secondary transfer nip. At this time, untransferred toner that has not been transferred to the recording medium P remains on the intermediate transfer belt 8.

Thereafter, the intermediate transfer belt 8 reaches the position of an intermediate transfer cleaning unit (not shown). At this position, the untransferred toner on the intermediate transfer belt 8 is collected.
Thus, a series of transfer processes performed on the intermediate transfer belt 8 is completed.

Here, the recording medium P transported to the position of the secondary transfer nip is transported from a paper feeding unit 26 disposed below the apparatus main body 100 via a paper feeding roller 27, a registration roller pair 28, and the like. It is a thing.
Specifically, a plurality of recording media P such as transfer paper are stored in the paper supply unit 26 in a stacked manner. When the paper feed roller 27 is driven to rotate counterclockwise in FIG. 1, the uppermost recording medium P is fed toward the rollers of the registration roller pair 28.

  The recording medium P transported to the registration roller pair 28 temporarily stops at the position of the roller nip of the registration roller pair 28 whose rotation drive has been stopped. Then, the registration roller pair 28 is rotationally driven in synchronization with the color image on the intermediate transfer belt 8, and the recording medium P is conveyed toward the secondary transfer nip. In this way, a desired color image is transferred onto the recording medium P.

Thereafter, the recording medium P on which the color image is transferred at the position of the secondary transfer nip is conveyed to the position of the fixing device 20. At this position, the color image transferred to the surface is fixed on the recording medium P by heat and pressure generated by the fixing belt and the pressure roller.
Thereafter, the recording medium P is discharged to the outside of the apparatus through the rollers of the discharge roller pair 29. The transferred P discharged from the apparatus by the discharge roller pair 29 is sequentially stacked on the stack unit 30 as an output image.
Thus, a series of image forming processes in the image forming apparatus is completed.

Next, the configuration and operation of the developing device in the image forming unit will be described in more detail with reference to FIG.
The developing device 5Y includes a developing roller 51Y facing the photosensitive drum 1Y, a doctor blade 52Y facing the developing roller 51Y, two conveying screws 55Y disposed in the developer accommodating portions 53Y and 54Y, and toner in the developer.

  Here, the developer G in the developing device 5Y is adjusted so that the ratio of toner in the developer (toner concentration) is within a predetermined range. Specifically, according to the toner consumption in the developing device 5Y, the toner accommodated in the toner container 32Y is replenished into the developer accommodating portion 54Y via the toner replenishing device 60Y (see FIG. 3 and the like). The The configuration and operation of the toner supply device will be described in detail later.

  Thereafter, the toner replenished in the developer accommodating portion 54Y is circulated through the two developer accommodating portions 53Y and 54Y while being mixed and stirred together with the developer G by the two conveying screws 55Y (perpendicular to the paper surface in FIG. 2). Direction movement.) The toner in the developer G is attracted to the carrier by frictional charging with the carrier, and is carried on the developing roller 51Y together with the carrier by the magnetic force formed on the developing roller 51Y.

  The developer G carried on the developing roller 51Y is conveyed in the direction of the arrow in FIG. 2 and reaches the position of the doctor blade 52Y. The developer G on the developing roller 51Y is conveyed to a position facing the photosensitive drum 1Y (development region) after the developer amount is made appropriate at this position. The toner is attracted to the latent image formed on the photosensitive drum 1Y by the electric field formed in the development area. Thereafter, the developer G remaining on the developing roller 51Y reaches above the developer containing portion 53Y as the sleeve rotates, and is detached from the developing roller 51Y at this position.

Is provided. The user attaches the toner container 32Y to the image forming apparatus main body 100 while grasping the grasping portion 33d (the movement of the toner container 32Y in the direction of the arrow in FIG. 18).

  Further, a spiral protrusion 33b is provided on the inner peripheral surface of the container body 33Y (a spiral groove when viewed from the outer peripheral surface side). The spiral projection 33b is for rotating and driving the container body 33Y in a predetermined direction to discharge the toner from the opening A. The container main body 33Y configured in this way can be manufactured by blow molding together with the gear 33c and the gripping portion 33d disposed on the peripheral surface thereof.

  Referring to FIG. 30, in toner container 32Y according to the first embodiment, stirring member 33f that rotates together with container body 33Y is fitted in bottle opening 33a (opening A) shown in FIG. The stirring member 33f is a rod-like member extending from the cavity in the cap portion 34Y toward the container main body 33Y. By rotating the stirring member 33 together with the opening A of the container main body 33Y, the toner discharging performance from the opening A is improved.

Referring to FIGS. 19 and 30, both members are engaged with the claw portion 34j (see FIG. 21 and the like) of the cap portion 34Y around the opening A of the container body 33Y. An engaged portion 33j (flange portion) for connecting 33Y and 34Y is formed so as to make one round of the outer periphery. Thus, the container main body 33Y is rotatably fitted to the cap portion 34Y.
Referring to FIGS. 19 and 30, the inner diameter of the head 33Yc (near the position where the gear 33c is formed) of the container body 33Y is equal to the accommodating portion 33Ya (spiral projection 33b) in which the toner is accommodated. Is formed so as to be smaller than the inner diameter. And in the container main body 33Y, between the head 33Yc and the accommodating part 33Ya, the pumping-up part 33Yb (the part enclosed with the dashed-dotted line of FIG. 20) formed so that the internal peripheral surface may protrude toward the inside. .) Is provided. Then, the toner conveyed toward the opening A by the spiral projection 33b with the rotation of the container body 33Y is pumped to the small diameter portion of the head 33Yc by the pumping portion 33Yb. Thereafter, the toner pumped to the small diameter portion of the head portion 33Yc is discharged from the opening A toward the cavity of the cap portion 34Y while being stirred by the stirring member 33f.

20 to 23, an ID chip 35 (information storage device), a shutter member 34d, a shutter seal 36, and the like are installed in the cap portion 34Y of the toner container 32Y.
Referring to FIG. 22, the cap portion 34Y roughly includes a cylindrical portion (a large-diameter cylindrical portion 34Y1, a medium-diameter cylinder) whose outer diameter and inner diameter are reduced in three stages from the container body 33Y side toward the shutter member 34d side. And a box portion (wide box portion 34Y11 and narrow box portion 34Y12) whose width in the horizontal direction is reduced in two steps at the bottom thereof. It has become.
The cap portion 34Y includes an insertion portion 34z including a large diameter cylindrical portion 34Y1, a medium diameter cylindrical portion 34Y2, a wide box portion 34Y11, and a portion of the narrow box portion 34Y12 (see FIG. 30). Is formed. The head portion 33Yc of the container main body 33Y and a part of the pumping portion 33Yb are inserted into the insertion portion 34z. Referring to FIG. 30 and the like, in this insertion portion 34z, the medium diameter cylindrical portion 34Y2 has an inner diameter D smaller than the tooth tip diameter of the gear 33c and smaller than the outer diameter of the opening A of the container body 33Y. It is formed to be large. The small diameter cylindrical portion 34Y3 is formed such that its inner diameter B is smaller than the inner diameter D of the medium diameter cylindrical portion 34Y2 and further smaller than the outer diameter of the opening A.
Further, the opening diameter of the annular vertical wall surface (the surface facing the periphery of the opening A of the container body 33Y) that connects the medium diameter cylindrical portion 34Y2 and the small diameter cylindrical portion 34Y3 is substantially the same as the inner diameter B. An annular cap seal 37 (elastic seal) is attached with a double-sided tape. The head 33Yc and a part of the pumping portion 33Yb are inserted into the insertion portion 34z so that the edge of the opening A of the head portion 33Yc of the container body 33Y comes into contact with the cap seal 37. With such a configuration, a part of the gear 33c (a part excluding a part exposed from the notch hole part 34x) and a functional part such as a connection part between the cap part 34Y and the container main body 33Y are provided in a large-diameter cylinder. It will be covered by the part 34Y1. Therefore, even when the toner container 32Y is held by the user alone, it is possible to prevent the user from touching such a functional part, and an unexpected external force (inadvertent blow or the like) is caused. Even if it is added to 32Y, it is possible to reduce toner leakage from the connecting portion and damage to the tooth surface of the gear 33c. Further, since the annular cap seal 37 has good slidability and elasticity maintenance on its surface, even if the container main body 33Y rotates while biting in, a gap is generated between the container main body 33Y and the cap portion 34Y, and toner is generated. There is no leakage. As a material for the cap seal 37, unlike a general flexible urethane foam (PUR), a high-density microcell urethane sheet having a high-density, fine and uniform cell structure is used. As a result, compared to the case where a general PUR is used, the cap seal 37 is less sticky, and the sealing performance between the container body 33Y and the cap portion 34Y can be maintained over a long period of time.

  Referring to FIGS. 22 and 30, the toner discharged from the opening A of the container body 33 </ b> Y is placed outside the container inside the narrow box part 34 </ b> Y <b> 12 located below the small diameter cylindrical part 34 </ b> Y <b> 3 of the cap part 34 </ b> Y. A toner dropping path C having a hexagonal column-like hole for discharging (falling its own weight) vertically downward is provided. The toner dropping path C has a constant flow path area with a hexagonal cross section, and communicates the lower peripheral surface of the small diameter cylindrical portion 34Y3 with the toner discharge port W (discharge port). As a result, the toner discharged from the opening A of the container body 33Y into the small diameter cylindrical portion 34Y3 of the cap portion 34Y falls by its own weight on the hexagonal columnar toner dropping path C and is discharged from the toner discharge port W to the outside of the container (toner tank). The portion 61Y) is smoothly discharged.

A part of the shutter member 34d (shutter main part 34d1) for opening and closing the toner discharge port W in conjunction with the attaching / detaching operation of the toner container 32Y to the toner container accommodating part 70 is provided at the bottom of the narrow box part 34Y12. ) Is slidably held.
22 and 23 show operations from when the shutter member 34d starts to open the toner discharge port W to when the opening is completed. FIGS. 24A to 24C are schematic views showing the opening operation of the shutter member 34d (shutter deforming portion 34d2) at that time. 25 and 26 are perspective views showing the shutter member 34d. 24B and 24C, the cap part 34Y, the cap receiving part 73, and the bottle receiving part 72 illustrated in FIG. 24A are partially omitted.

  Referring to FIGS. 22 to 26, shutter member 34d is formed of a resin material such as polystyrene. Roughly, plate-like shutter main portion 34d1 projects from shutter main portion 34d1 and from shutter main portion 34d1. And a shutter deforming portion 34d2 having a small thickness and elasticity.

Referring to FIGS. 25 and 26, the shutter main portion 34d1 of the shutter member 34d has a vertical wall 34d13 (a vertical wall extending in parallel with the mounting direction of the toner container 32Y) that stands on both side ends. In addition, shutter sliders 34d12 made of a plurality of protrusions protruding from the vertical wall 34d13 are formed at both end portions. The shutter slider 34d12 is the same as the slide protrusion 34d12a protruding on the inner surface of the vertical wall 34d13, the L-shaped engaged protrusion 34d12b protruding on the outer surface of the vertical wall 34d13, and the engaged protrusion 34d12b. And a pair of prismatic portions 34d12c that project from the outer surface and extend from the main body of the shutter main portion 34d1 toward the wide box portion 34d11. On the other hand, in the narrow box portion 34d12 of the cap portion 34Y, a pair of slide grooves 34t (see FIG. 23) extending in the longitudinal direction on both side walls are formed by ribs. By fitting the slide protrusion 34d12a into the slide groove 34t, the shutter main part 34d1 of the shutter member 34d is supported by the cap part 34Y so as to be slidable.
Further, a shutter seal 36 as a seal member is attached to the upper surface of the shutter main portion 34d1 (the surface facing the toner discharge port W). The shutter seal 36 is a thin, substantially rectangular parallelepiped elastic seal and, like the cap seal 37, uses a high-density microcell urethane sheet as a material in consideration of surface slidability and elasticity maintenance. Therefore, even when the opening / closing operation of the shutter member 34d is repeated, the sealing performance at the toner discharge port W in the state where the shutter member 34d closes the toner discharge port W can be maintained.
The slide protrusion 34d12a of the shutter slider 34d12 is fitted in the slide groove 34t of the narrow box portion 34Y12 (cap portion 34Y). Further, in this state, a hexagonal ring-shaped projection 34r (see FIG. 23) projecting downward along the edge of the hexagonal toner discharge port W of the narrow box portion 34Y12, a shutter main portion 34d1, The shutter seal 36 is sandwiched between the shutter seal 36 and the shutter seal 36 is slightly compressed. In such a state, the shutter member 34d moves along the slide groove 34t, whereby the shutter main portion 34d1 opens and closes the toner discharge port W while suppressing toner leakage. Further, in the state where the shutter main portion 34d1 (shutter member 34d) closes the toner discharge port W, the toner is prevented from leaking from between the shutter main portion 34d1 and the toner discharge port W.

  Specifically, the shutter member 34d opens the toner discharge port W by the relative movement in the longitudinal direction from the cap portion 34Y side to the container body 33Y side (movement to the left in FIG. 30). Thus, the toner discharge port W is closed by relative movement in the longitudinal direction from the container main body 33Y side to the cap portion 34Y side (movement to the right in FIG. 30). The opening / closing operation of the shutter member 34d (the opening / closing operation of the toner discharge port W) is performed in conjunction with the attaching / detaching operation of the toner container 32Y in the longitudinal direction with respect to the toner container housing portion 70 (apparatus main body 100).

  Referring to FIGS. 25 and 26, the shutter deforming portion 34d2 of the shutter member 34d is formed integrally with the shutter main portion 34d1, and has a plate thickness thinner than the plate thickness of the shutter main portion 34d1 as described above. ing. The shutter deforming portion 34d2 mainly connects two elongated flat plate portions 34d23 extending from the end surface of the shutter main portion 34d1 on the container main body 33Y side, and these two flat plate portions 34d23 are connected to each other in the vicinity of the distal end portion (free end). And a plate-like member 34d24 extending in a direction orthogonal to the longitudinal direction. The shutter deforming portion 34d2 is formed so as to be elastically deformable in the vertical direction with a fixed end (connecting portion) to the shutter main portion 34d1 as a base point. A stopper portion 34d22 for fixing the shutter member 34d is formed at the front end portions (free ends) of the two flat plate portions 34d23 to prevent the toner discharge port W from being inadvertently opened as will be described later. Further, on the bottom surface side of the plate-like member 34d24, there is an inclined protrusion (a cross section is a triangle) protruding in a mountain shape downward in the vertical direction, and as will be described later, a stopper releasing bias of the cap receiving portion 73 is provided. A stopper releasing portion 34d21 for releasing the fixing of the shutter member 34d described above is formed in cooperation with the portion 72b.

Referring to FIGS. 22 and 23, the wide box portion 34Y11 located below the large-diameter cylindrical portion 34Y1 of the cap portion 34Y has a shutter housing portion 34n for housing the shutter deformation portion 34d2 when the shutter is opened. Is formed. Of the four side surfaces of the wide box portion 34Y11, two side surfaces facing the longitudinal direction (the direction of the arrow in FIG. 22) are open. In particular, the side surface formed on the toner discharge port W side has an opening 34n1 that extends in the horizontal direction, although a part of the wall surface is formed at both ends on the bottom side. The opening 34n1 is formed so as to cut out two surfaces, that is, a side surface on the toner discharge port W side of the wide box portion 34Y11 and a bottom surface. And the edge part formed so that it may stand upright from the bottom face of wide box part 34Y11 among the edge parts of opening 34n1 may be contact part 34n5.
The stopper portion 34d22 of the shutter deforming portion 34d2 is located at the extreme end (the front end of the shutter deforming portion 34d2 away from the shutter main portion 34d1) in the opening direction of the shutter deforming portion 34d2 (the left direction in FIG. 24). The formed wall portion is in contact with the above-described contact portion 34n5, thereby restricting the movement of the shutter member 34d from the state in which the toner discharge port W is closed to the direction in which the toner discharge port W is opened. That is, the toner container 32Y is in a single state (in a state where it is not set in the apparatus main body 100), and since the stopper portion 34d22 of the shutter member 34d is in contact with the contact portion 34n5, the shutter member 34d is It does not occur that the toner discharge port W is opened independently by moving in the opening direction.
On the other hand, the stopper release portion 34d21 is linked to the stopper release urging portion 72b (see FIGS. 5, 24, etc.) formed in the bottle receiving portion 72 in conjunction with the mounting operation of the toner container 32Y to the toner container housing portion 70. .) Is pushed up and pushed upward by the stopper release biasing portion 72b (by receiving an external force from below), the shutter deforming portion 34d2 is elastically deformed upward and the stopper portion 34d22 is also displaced upward. . Thus, the contact state between the stopper portion 34d22 and the contact portion 34n5 is released, and the shutter member 34d can be moved in the opening direction.

Hereinafter, the operation of the shutter member 34d in conjunction with the operation of attaching the toner container 32Y to the toner container housing portion 70 will be described in detail with reference to FIGS. Note that the position of the shutter member 34d in FIGS. 24A and 24C corresponds to the position of the shutter member 34d in FIGS. 22 and 23, respectively.
As shown in FIG. 24A, the stopper formed on the bottle receiving portion 72 is started by the operation of attaching the toner container 32Y to the toner container housing portion 70 (the movement to the right in FIG. 24). When the stopper release portion 34d21 of the shutter member 34d has not reached the position of the release biasing portion 72b (see FIG. 5 and the like), the stopper portion 34d22 of the shutter member 34d is in contact with the contact portion 34n5, Movement of the shutter member 34d in the opening direction is restricted. A bristle brush 72f is arranged on the upper surface of the bottle receiving portion 72 and on the side of the cap receiving portion 73 near the stopper release biasing portion 72b so as to clean the dirt by rubbing the bottom surface of the shutter member 34d. ing. The bristle brush 72f is particularly effective in cleaning the fumed toner adhering to the bottom surface of the shutter member 34d during the operation of removing the toner container 32Y.
Thereafter, when the mounting operation of the toner container 32Y proceeds, as shown in FIG. 24B, the stopper releasing portion 34d21 is pushed up by the stopper releasing urging portion 72b, and the shutter deforming portion 34d2 is surrounded by a connection line (a chain line). It is elastically deformed from the base point. Thereby, the contact state between the stopper portion 34d22 and the contact portion 34n5 is released, and the shutter member 34d can be relatively moved in the opening direction.
Thereafter, the shutter member 34d abuts against a wall portion (a portion marked “contact position” in the drawing) formed around the toner supply port 73w of the cap receiving portion 73, and the toner container housing portion. 70 (cap receiving portion 73) is restricted from moving (shutter member 34d will never move in the longitudinal direction). However, since the movement in the mounting direction of the toner container 32Y is advanced, the shutter member 34d moves relative to the toner discharge port W in the opening direction. That is, as shown in FIG. 24C, the shutter member 34d moves relatively to the container body 33Y side, and the shutter deforming portion 34d2 is housed in the shutter housing portion 34n. Thus, the toner discharge port W is completely opened by the movement of the shutter member 34d in the opening direction, and the toner discharge port W and the toner replenishment port 73w of the cap receiving portion 73 coincide with each other so as to coincide with each other. An integral toner replenishing passage that communicates with the toner replenishing device is formed. At this time, the stopper release portion 34d21 of the shutter member 34d is stored in a notch 34n6 (also see FIGS. 22, 23, etc.) that is an extension of the opening 34n1 of the shutter storage portion 34n. Accordingly, it is possible to prevent a problem that the shutter deformation portion 34d2 stored in the shutter storage portion 34n is held in a state of being largely elastically deformed by the contact between the stopper release portion 34d21 and the shutter storage portion 34n. .

  As described above, in the toner container 32Y according to the first embodiment, the shutter member 34d is provided with the shutter deforming portion 34d2 that is elastically deformed based on the connection position with the shutter main portion 34d1, and the shutter deforming portion 34d2 includes the shutter member. Since the stopper portion 34d22 that restricts the movement of the opening 34d in the opening direction and the stopper release portion 34d21 that releases the stopper 34d21 are provided, the shutter member 34d opens the toner discharge port W without permission when the toner container 32Y is a single unit. The shutter member 34d opens the toner discharge port W in conjunction with the mounting operation only when the toner container 32Y is set in the image forming apparatus main body 100.

Hereinafter, an operation of the L-shaped engaged protrusion 34d12b relating to the shutter opening / closing operation will be described.
As shown in FIG. 25 and the like, the L-shaped engaged protrusions 34d12b are respectively formed at both end portions of the shutter main portion 34d1. On the other hand, although not shown in the figure of Japanese Patent Application No. 2011-9784, a pair of urging members are installed on the bottom surface inside the cap receiving portion 73 so as to face the pair of engaged protrusions 34d12b. ing. The pair of urging members are L-shaped levers having symmetrical shapes (a support shaft serving as a rotation center is formed near the bent portion of the L-shape), and an arm portion on one end side thereof. Is biased by a torsion coil spring. When the toner container 32Y (cap portion 34Y) is attached to the cap receiving portion 73, the arm portion on the other end side of the biasing member is engaged with the engaged protrusion 34d12b, and the shutter member 34d is opened. The urging force is applied in a direction (a closing direction) against the direction to be applied. As a result, the user pushes in the toner container 32Y with a force that overcomes the biasing force by the biasing member described above, and the shutter member 34d is quickly opened. As a result, a state in which the toner discharge port W does not coincide with the toner supply port 73w of the cap receiving portion 73 occurs only momentarily, and toner leakage from between the toner discharge port W and the toner supply port 73w is suppressed. can do.
On the other hand, when the toner container 32Y (cap portion 34Y) is detached from the cap receiving portion 73, the arm portion of the biasing member described above is biased so as to push the engaged protrusion 34d12b in the mounting direction. Become. Accordingly, the user tries to pull out the toner container 32Y with a force that overcomes the urging force of the urging member described above, so that the shutter member 34d is quickly closed. As a result, as in the opening operation, toner leakage from between the toner discharge port W and the toner supply port 73w can be suppressed.

Referring to FIGS. 20, 21, 30, and the like, a first positioning hole portion extending in the longitudinal direction from the end surface of the cap portion 34 </ b> Y orthogonal to the longitudinal direction is formed in the upper portion (ceiling portion) of the cap portion 34 </ b> Y. 34a is formed. The first positioning hole 34 a serves as a main positioning reference for the cap 34 </ b> Y in the image forming apparatus main body 100. Specifically, in conjunction with the operation of attaching the toner container 32Y in the longitudinal direction to the toner container housing portion 70, the main reference pin 73a (as a positioning pin of the cap receiving portion 73 is inserted into the first positioning hole portion 34a of the cap portion 34Y. 14 and 17 etc. can be referred to).
Further, the second positioning hole 34b extending in the longitudinal direction from the end surface of the cap 34Y orthogonal to the longitudinal direction does not reach the position of the toner discharge port W at the lower portion (bottom) of the cap portion 34Y. Is formed. The second positioning hole 34b serves as a positioning reference for the cap 34Y in the image forming apparatus main body 100. Specifically, in accordance with the operation of mounting the toner container 32Y in the toner container housing portion 70 in the longitudinal direction, the secondary reference pin 73b (as a positioning pin of the cap receiving portion 73) is inserted into the second positioning hole 34b of the cap portion 34Y. 14 and 17 etc. can be referred to). As shown in FIG. 21, the second positioning hole 34b has a vertical direction in the longitudinal direction (this "longitudinal direction" is different from the meaning of the "longitudinal direction" of the toner container 32Y described elsewhere. )).
The positioning of the cap portion 34Y in the toner container housing portion 70 is performed by the two positioning holes 34a and 34b configured as described above.

  Here, referring to FIG. 30 and the like, the depth of the first positioning hole 34a is set longer than the depth of the second positioning hole 34b. The length of the main reference pin 73a in the longitudinal direction is set longer than the length of the sub reference pin 73b in the longitudinal direction. Thereby, in the mounting operation in the longitudinal direction of the toner container 32Y to the toner container housing part 70 (cap receiving part 73), the fitting of the main reference pin 73a to the first positioning hole 34a serving as the positioning main reference is started. After that, the fitting of the slave reference pin 73b to the second positioning hole 34b serving as the positioning slave reference is started, and the toner container 32Y is inserted into the toner container housing portion 70 (cap receiving portion 73). Smooth installation is possible. In addition, since the first positioning hole 34a that is long in the longitudinal direction is provided in the ceiling portion (the portion that is not buried in the toner) of the cap portion 34Y, the first positioning hole portion 34a in the cap portion 34Y. There is no influence on the toner transportability (fluidity). The second positioning hole 34b that is short in the longitudinal direction is provided at the bottom of the cap 34Y, but can be installed using a short space from the end surface of the cap 34Y to the position of the toner discharge port W. Thus, it fully functions as a positioning sub-reference.

  Further, referring to FIG. 20 and the like, it extends above the first positioning hole 34a of the cap portion 34Y and extends along the axial direction of the first positioning hole 34a to the outer peripheral portion of the cap portion 34Y. An existing guide rail portion 34e is formed. The guide rail portion 34e is axisymmetric with respect to a virtual perpendicular passing through the hole center of the first positioning hole portion 34a when viewed in a cross section perpendicular to the longitudinal direction (a cross section parallel to the front view of FIG. 21). So as to project upward in the vertical direction from the outer peripheral surface of the cap portion 34Y and extend in the longitudinal direction (the vertical direction in FIG. 21). Prior to insertion of the main reference pin 73a into the positioning hole 34a, the guide rail portion 34e is an inner wall of the cap receiving portion 73 and is located above the main reference pin 73a and upstream of the tip end portion of the main reference pin 73a in the mounting direction. It fits in a contacted groove 73m (concave portion) formed in a groove shape from the side, and extends in the horizontal direction perpendicular to the longitudinal direction of the cap portion 34Y when moving to the image forming apparatus main body 100 (cap receiving portion 73). Regulate posture. In addition, a protruding portion 34e1 that slightly protrudes in the longitudinal direction (mounting direction) with respect to the end surface of the first positioning hole 34a is formed at the tip of the guide rail portion 34e. The protrusion 34e1 is formed in a tapered shape as shown in FIG. Then, the guide rail portion 34 e enters the contacted groove 73 m formed in the cap receiving portion 73, and the cap portion 34 Y is guided into the cap receiving portion 73. Accordingly, when the cap portion 34Y is attached to the cap receiving portion 73, the tapered protrusion 34e1 in the first positioning hole portion 34a is fitted between the first positioning hole portion 34a and the main reference pin 73a. The cap portion 34Y is smoothly attached to the cap receiving portion 73 because the fitting is made in the contact groove 73m before the fitting.

Referring to FIGS. 20 and 21 and the like, lateral sides that regulate the posture of the cap portion 34Y in the rotation direction of the image forming apparatus main body 100 (cap receiving portion 73) are respectively provided on both side portions of the cap portion 34Y. A protrusion 34c is formed. The side projection 34c is a virtual horizontal line passing through the midpoint of an imaginary line segment connecting the hole center of the first positioning hole 34a and the hole center of the second positioning hole 34b when viewed in a cross section orthogonal to the longitudinal direction. It protrudes from the outer peripheral surface of the cap portion 34Y to both sides in the horizontal direction so as to be disposed on the line, and extends in the longitudinal direction (the direction perpendicular to the paper surface of FIG. 21). Then, the two side protrusions 34c are pushed in the cap receiving portion 73 by the cap portion sandwiching member 73r (see FIG. 12 and the like) so as to be pushed back in the opposite direction to the pushing, as shown in FIG. The cap portion 34Y is attached to and detached from the cap receiving portion 73 while engaging the lateral groove 73h and the groove portion 73r1 shown in FIG. The posture of the cap portion 34Y in the rotational direction in a state where the is mounted is regulated.
More specifically, as shown in FIG. 20 and the like, the side protrusion 34c has a tapered tip in the longitudinal direction (mounting direction). Here, when the cap portion 34Y is attached to the cap receiving portion 73, first, the guide rail portion 34e is fitted into the contacted groove 73m, and then the tip is tapered. Since the side protrusions 34c are fitted in the side grooves 73h and the groove portions 73r1, the cap receiving portion 73 is smoothly mounted while the posture of the cap portion 34Y is reliably regulated.
Referring to FIGS. 20 and 21, convex portions 34g and 34h are provided at both ends of the bottom portion of the cap portion 34Y to ensure incompatibility of the toner container 32Y (developer container). More specifically, convex portions 34g and 34h project upward from the upper surface side of a flat blade member extending from the bottom of the cap portion 34Y to the side. The convex portions 34g and 34h are fitted portions 72m shown in FIG. 9 when the operation of mounting the toner container 32Y to the toner container housing portion 70 is correct (when the toner container housing portion 70 is mounted at the regular position). (It is formed in the bottle receiving part 72 of the toner container accommodating part 70).
Specifically, although not shown, the positions of the convex portions 34g and 34h are arranged at different positions depending on the color of the toner stored in the toner container (container body). Specifically, when the front end in the mounting direction when the toner container 32Y is mounted on the image forming apparatus main body 100 is the front, the protruding portions 34g and 34h do not overlap with each other when viewed from the front. And at different positions depending on the color. The convex portions 34g and 34h of the toner container corresponding to cyan are formed at positions where only the cyan fitting portion 72m of the toner container accommodating portion 70 is fitted, and the convex portions 34g and 34h of the toner container corresponding to magenta are the toner. The convex portions 34g and 34h of the toner container corresponding to yellow are formed only at the fitting portion 72m for magenta of the container housing portion 70, and only the yellow fitting portion 72m of the toner container housing portion 70 is formed. The convex portions 34g and 34h of the toner container corresponding to black are formed at positions where they are fitted to only the black fitting portion 72m of the toner container housing portion 70.
With such a configuration, a toner container of a different color (for example, a yellow toner container) is set in a toner container storage section of a predetermined color (for example, a cyan toner container storage section), and A problem that a desired color image cannot be formed is suppressed. That is, erroneous setting of the toner container in the toner container housing portion is suppressed.
FIG. 10 shows a state in which the operation of attaching the toner container 32Y to the toner container housing portion 70 is correct. The convex portions 34g and 34h of the cap portion 34Y are fitted to the fitting portion 72m of the bottle receiving portion 72. There is no interference. On the other hand, FIG. 11 shows a state in which the operation of attaching the toner container 32Y to the toner container housing portion 70 is not correct. The convex portion of the cap portion 34Y protrudes from the fitting portion 72m of the bottle receiving portion 72. The parts 34g and 34h interfere with each other.

Hereinafter, the ID chip 35 (information storage device) characteristic of the toner container 32Y (detachable device) according to the first embodiment will be described in detail.
Referring to FIG. 20 and the like, various electronic information is provided on the end face of the cap portion 34Y at the position of the holding member 34k installed between the first positioning hole portion 34a and the second positioning hole portion 34b. Is installed as an information storage device in which is stored. The ID chip 35 is configured to be connected to the connector 73e of the cap receiving portion 73 in a state where the cap portion 34Y is attached to the toner container housing portion 70 (cap receiving portion 73) (FIGS. 3 and 17). Etc.). Specifically, the plurality of metal pads 35a (metal plate) of the ID chip 35 and the plurality of main body side terminals 73e2 of the connector 73e in a state where the cap portion 34Y is attached to the toner container housing portion 70 (cap receiving portion 73). And contact. The ID chip 35 performs communication (wired communication) with the control unit 90 via the connector 73e as shown in FIG. 3 with the cap unit 34Y held by the cap receiving unit 73.

27 to 29, in the first embodiment, the holding mechanism installed in the toner container 32Y (detachable device) detachably installed on the image forming apparatus main body 100 is an information storage device. As an ID chip 35, a holding member 34k as a holding portion, and the like. The ID chip 35 as an information storage device held by the holding mechanism includes a substrate 35b, an information storage unit 35c, a metal pad 35a (metal plate) as a plurality of terminals, and the like.
Referring to FIG. 29, the information storage unit 35c is an electronic circuit that stores various information exchanged between the control unit 90 of the image forming apparatus main body 100 and the toner container 32Y. In FIG. 29, a box shape is indicated by hatching for simplification, but a collection of memory ICs, capacitors for reducing noise, resistors, and the like is applicable. The information storage unit 35c is disposed on the back side of the substrate 35b (the side facing the end surface of the cap unit 34Y), and is electrically connected to all or part of the metal pads 35a as a plurality of metal plates. It is connected.
The metal pads 35a serving as a plurality of terminals come into contact with the plurality of main body side terminals 73e2 in the connector 73e installed in the cap receiving section 73 (the apparatus main body 100), respectively, and contact the image forming apparatus main body 100 (the control section 90). Electric signals related to information are exchanged between them. The plurality of metal pads 35a are arranged on the front surface side (the side facing the cap receiving portion 73) of the substrate 35b. The plurality of metal pads 35a are formed in a substantially rectangular shape, and are arranged in parallel with a gap in the short direction (the Z direction (vertical direction) in FIG. 29A).
On the substrate 35b on which the information storage part 35c and the metal pad 35a are arranged, a positioning cutout part 35b1 (one shape when divided into two by an oval circumferential linear part) is provided at both ends in the vertical direction. Is formed. This positioning notch 35b1 is fitted to a positioning pin 73e3 (refer to FIGS. 16, 17, etc.) as a positioning columnar projection provided on the connector 73e (image forming apparatus main body 100). Thus, the positions of the plurality of metal pads 35a with respect to the plurality of main body side terminals 73e2 are determined.
The ID chip 35 (information storage device) configured in this manner is held by a holding member 34k (holding portion) configured to be detachable from the cap portion 34Y.

The holding member 34k (holding portion) intersects the moving direction (the direction indicated by the white arrow in FIG. 17) when the metal pad 35a (terminal) approaches and comes into contact with the main body side terminal 73e2. A contact-type ID chip 35 (information storage device) is held so that it can move on a virtual plane (which is a substantially orthogonal virtual plane).
Specifically, in the first embodiment, the holding member 34k can move on a virtual plane (XZ plane in FIG. 20) orthogonal to the attaching / detaching direction of the toner container 32Y with respect to the image forming apparatus main body 100. The ID chip 35 (substrate 35b) is held. In other words, the ID chip 35 (substrate 35b) can be freely moved to some extent on the XZ plane of FIG. 20 (with a movement of about 1 mm) while being held by the holding member 34k (cap portion 34Y) as shown in FIG. Yes.) It is configured to be able to. Specifically, the ID chip 35 (substrate 35b) is loosely held to some extent inside a box-shaped holding member 34k (holding mechanism). That is, the ID chip 35 is held inside the holding member 34k with a predetermined interval in the XZ plane direction between the side wall and the side wall. Referring to FIGS. 28 and 29, ID chip 35 has a slight gap Δt in the ± Y direction with respect to thickness t (about 0.8 mm) of substrate 35b inside holding member 34k. (For example, Δt + t = 0.85 to 1.05 mm) is held. Therefore, the substrate 35b can be erected so as to be orthogonal to the insertion direction of the positioning pin 73e3 to some extent. Thereby, the board | substrate 35b falls too much with respect to the insertion direction of the positioning pin 73e3, the positioning pin 73e3 and the notch part 35b1 are twisted, and the malfunction that fitting of both members cannot be suppressed is suppressed.
With the configuration as described above, with the miniaturization of the image forming apparatus 100 and the toner container 32Y, the plurality of metal pads 35a (terminals) on the substrate 35b are provided so as to miniaturize the ID chip 35 installed therein. Even when densely arranged, contact failure occurs due to poor positioning between the plurality of metal pads 35a and the main body side terminal 73e2 of the connector 73e regardless of the dimensional accuracy and assembly accuracy of related parts. It becomes difficult.

Specifically, referring to FIG. 17 and the like, when the mounting operation of the cap portion 34Y of the toner container 32Y to the cap receiving portion 73 is advanced, the positioning pins 73a and 73b are inserted into the positioning holes 34a and 34b, The cap part 34Y in the cap receiving part 73 is positioned. When the mounting operation of the cap portion 34Y is further advanced, the positioning pin 73e3 (see FIGS. 16, 17, etc.) of the connector 73e is inserted into the cutout portion 35b1 of the substrate 35b in the ID chip 35, and the connector 73e (see FIG. 16, FIG. 17). The substrate 35b (the plurality of metal pads 35a) is positioned with respect to the plurality of main body side terminals 73e2). More specifically, the positioning pin 73e3 comes into contact with the edge (or the inner surface) of the notch 35b1 to restrict the movement of the substrate 35b. At this time, since the ID chip 35 (substrate 35b) in which the notch 35b1 is formed is configured to be movable on the XZ plane in the holding member 34k, the dimensional accuracy and assembly accuracy of the related parts accompanying mass production are increased. As a result of having to increase the allowable variation, even when the positioning of the toner container 32Y and the image forming apparatus main body 100 is performed, even if the position of the notch 35b1 is deviated from the initial position with respect to the positioning pin 73e3, Since the ID chip 35 (substrate 35b) itself moves in the XZ plane by being regulated by the tapered shape at the tip of the positioning pin 73e3, the cylindrical portion of the positioning pin 73e3 and the notch 35b1 can be fitted. In other words, the cylindrical portion of the positioning pin 73e3 and the notch 35b1 can be fitted independently of the positioning of the toner container 32Y and the image forming apparatus main body 100.
Therefore, poor contact due to poor positioning between the plurality of metal pads 35a and the main body side terminal 73e2 of the connector 73e is less likely to occur.

Here, referring to FIG. 27, holding member 34k as a holding portion is configured to be detachable from cap portion 34Y, and insertion port 34k1 for inserting / removing ID chip 35 is formed upward. It is a box-shaped member.
Specifically, when the holding mechanism is assembled to the cap portion 34Y, first, the ID chip 35 (information storage device) is inserted from the insertion port 34k1 toward the inside of the holding member 34k (the movement in the direction of the arrow in FIG. 27). .) Thereafter, the holding member 34k (holding portion) with the ID chip 35 attached is moved in the direction of the arrow in FIG. 27 and press-fitted into the concave portion of the cap portion 34Y. At this time, the holding member 34k is fixed and held at a position in contact with a pedestal portion 34q (disposed at a position not in contact with the substrate 35b) provided in the concave portion of the cap portion 34Y. In addition, when taking out ID chip 35 from the cap part 34Y, the operation | work is performed in the reverse procedure to the procedure mentioned above. The pedestal portion 34q is a rib that rises in the concave portion of the cap portion 34Y in the mounting direction of the toner container 32Y (or toward the holding member 34k), and from the place where the positioning pin 73e3 of the connector 73e is inserted. It is provided at a position that is off.
In the first embodiment, the holding member 34k is press-fitted into and fixed to the concave portion of the cap portion 34Y. However, the holding member 34k is attached to the concave portion of the cap portion 34Y and fixed with screws. It can also be configured. Specifically, a piece-like rib having a hole on the side wall of the holding member 34k is projected to form a female screw portion on the end surface of the cap portion 34Y. Then, the holding member 34k is mounted in the concave portion of the cap portion 34Y, and the cap member 34k is in contact with the end surface of the cap portion 34Y through the rib portion of the holding member 34k. A screw is screwed into the female screw portion of the portion 34Y. Even in such a configuration, the holding member 34k can be attached to and detached from the cap portion 34Y relatively easily.

  Thus, since the ID chip 35 (substrate 35b) is configured to be detachable from the cap portion 34Y, the assembling property of the ID chip 35 (substrate 35b) to the toner container 32Y as a detachable device is improved. In addition, the efficiency of disassembling the ID chip 35 (substrate 35b) when the toner container 32Y is recycled is increased. In particular, the substrate 35b of the ID chip 35 in the first embodiment is a small substrate of about 12 mm × 8 mm to 15 mm × 10 mm, and data input / output in a state where the substrate 35b is attached to the cap portion 34Y in the manufacturing process ( When data input / output is performed by bringing the probe terminal into contact with the metal pad 35a), it is difficult to work on the cap portion 34Y having a complicated shape, and the process time may be prolonged. Therefore, the ID chip 35 (substrate 35b) is configured to be detachable as in the first embodiment so that the data input / output operation can be performed on the ID chip 35 alone (or for each holding member 34k) as necessary. The effect to make is great.

Referring to FIGS. 17 and 27, the cap portion 34Y is formed with an upright portion 34f that closes the insertion port 34k1 in a state where the holding member 34k is mounted in the recess.
Thereby, after the ID chip 35 (holding member 34k) is mounted on the cap portion 34Y, the problem that the ID chip 35 falls off from the insertion port 34k1 of the holding member 34k is suppressed.

Referring to FIG. 28, a first facing portion 34k4 and a second facing portion 34k5 are formed inside the holding member 34k (box-shaped member). The first facing portion 34k4 faces the first plane of the substrate 35b (refer to FIG. 29, which is a surface on which the plurality of metal pads 35a are arranged) and prevents the plurality of metal pads 35a from interfering with each other. The metal pad 35a is formed so as to be slidable by contact with the outer peripheral area of the first plane where the metal pad 35a is not disposed. The second facing portion 34k5 faces the second plane of the substrate 35b (the surface on which the information storage portion 35c is disposed with reference to FIG. 29), and the second facing portion 34k5 does not interfere with the information storage portion 35c. A part of the plane is formed to be slidable. As a result, the ID chip 35 can freely move in the XZ plane within the holding member 34k without falling off the holding member 34k and without damaging the metal pad 35a or the information storage unit 35c. (It can move so as to slide on the opposing portions 34k4, 34k5).
Furthermore, openings 34k2 and 34k3 are formed on the front and back surfaces of the holding member 34k, respectively. The first opening 34k2 is formed such that the plurality of metal pads 35a and the positioning notches 35b1 are exposed to the side facing the connector 73e even if the substrate 35b moves to some extent in the XZ plane. Thereby, the above-described engagement between the positioning pin 73e3 and the notch 35b1 accompanying the movement of the substrate 35b in the XZ plane and the connection (contact) between the metal pad 35a and the main body side terminal 73e2 become possible. Note that the second opening 34k3 is formed so that the information storage unit 35c is exposed to the side facing the recess of the cap unit 34Y even if the substrate 35b moves in the XZ plane to some extent.
Referring to FIG. 28, the opening 34k2 formed on the front surface of the holding member 34k has a convex shape on the left side and a concave shape on the right side. As a result, the region surrounded by the broken line in FIG. 28 functions as a “hook (stopper)” that prevents the ID chip 35 from falling off the opening 34k2.

FIG. 29 is a trihedral view showing the ID chip 35.
As shown in FIG. 29, on the first plane of the substrate 35b in the ID chip 35, four metal pads 35a as metal plates are arranged in parallel in the Z direction. The metal pad 35a is a multilayer structure composed of a copper layer, a nickel layer, and a gold layer from the substrate 35b side, and the gold layer as the surface layer is provided for the purpose of preventing oxidation although it is relatively expensive. . Further, the metal pad 35a is formed by electric field vapor deposition on the substrate 35b masked in advance.
The positioning notches 35b1 are formed at both ends of the four metal pads 35a in the arrangement direction (in the Z direction) so as to sandwich the four metal pads 35a. In the first embodiment, the first virtual straight line S1 passing through the center of the notch 35b1 and parallel to the arrangement direction of the plurality of metal pads 35a connects the centers in the longitudinal direction of the plurality of metal pads 35a. The second virtual straight line S2 is configured so as not to overlap. Specifically, the first virtual straight line S1 connecting the two positioning notches 35b1 (the original elongated holes in the respective notched portions 35b1 having one shape when the elongated holes are equally divided into two in the longitudinal direction) Is a position that does not overlap with the second virtual straight line S2 that connects the centers in the longitudinal direction of the plurality of metal pads 35a. In other words, the imaginary straight line S1 that connects the portions of the cutout 35b1 that are most biting inward toward the inside of the substrate 35b is configured so as not to overlap the imaginary straight line S2. Further, the virtual straight line S1 is configured to be substantially parallel to the virtual straight line S2.
Here, in the first embodiment, the dimensions a to f in FIG. 29 are set to 6.2 mm, 5.2 mm, 1.5 mm, 2 mm, 6 mm, and 11.7 mm, respectively. As described above, the substrate 35b having a small area has a small absolute deflection amount even if an external force is applied, and has a relatively high resistance (rigidity) to the shearing force. In the first embodiment, the ID chip 35 is movably held inside the holding member 34k. If the ID chip 35 has a large area, it is “squeezed” (notched) by inserting the positioning pin 73e3 into the notch 35b1. The positioning pin 73e3 is not perpendicular to the portion 35b1, but enters the slant, and the sliding load between the two 35b1 and 73e3 increases, so that the substrate 35b is bent and cannot move). Although employed, as described above, the positioning method is established by making the best use of the small area of the substrate 35b to increase the rigidity and to prevent the occurrence of bending that causes “twisting”. Further, although the distance between the metal pads 35a on the substrate 35b is narrow, the contact failure between the metal pad 35a and the body side terminal 73e2 is suppressed by the high-precision positioning accompanying the movement of the substrate 35b in the XZ plane. Therefore, the area of the expensive metal pad 35a including the gold layer can be minimized.

FIG. 16 is a schematic perspective view showing the connector 73e on the apparatus main body 100 side.
Referring to FIG. 16, the four main body side terminals 73e2 in the connector 73e are plate-shaped (or linear) metal members, one end of which is a fixed end and the other end is a free end. Fixedly supported. Further, the four main body side terminals 73e2 are formed with curved portions that are curved toward the ID chip 35 (toner container 32Y) on the other end side. That is, the main body side terminal 73e2 is bent like a knee (or boomerang) toward the ID chip 35. The curved portion of the main body side terminal 73e2 is a portion that becomes a contact point with the metal pad 35a.
Then, with the mounting operation of the cap part 34Y (toner container 32Y) to the cap receiving part 73, first, the curved part of the main body side terminal 73e2 comes into contact with the substantially central part in the longitudinal direction of the metal pad 35a. When the mounting operation of the cap portion 34Y further proceeds, the ID chip 35 (substrate 35b) further approaches the connector 73e side, and the main body side terminal 73e2 is pressed against the metal pad 35a to be elastically deformed (the bent knee is extended). The curved portion of the main body side terminal 73e2 is displaced so as to approach the first virtual straight line S1. That is, as the cap portion 34Y is attached, the bending portion of the main body side terminal 73e2 gradually increases the contact pressure against the metal pad 35a while the left side of FIG. 29 (near the first virtual straight line S1). It will slide towards.
With such a configuration, the position of the cap portion 34Y (metal pad 35a) in the longitudinal direction (Y direction) with respect to the cap receiving portion 73 (main body side terminal 73e2) due to the dimensional accuracy and assembly accuracy of related parts (dimensional variation). Even if they deviate, it is possible to reliably prevent a contact failure between the main body side terminal 73e2 and the metal pad 35a. Further, finally, the main body side terminal 73e2 and the metal pad 35a are in contact with each other in the vicinity of the position where the positioning pin 73e3 and the notch 35b1 are engaged (in the vicinity of the first virtual straight line S1). The horizontal distance from the positioning portion to the contact portion can be reduced. As a result, the accuracy of the contact position between the main body side terminal 73e2 and the metal pad 35a is improved.

In the first embodiment, the plurality of metal pads 35a are arranged side by side so that the arrangement direction is the vertical direction (Z direction).
Thus, the positioning direction of the cap portion 34Y in the cap receiving portion 73 (the alignment direction of the positioning pins 73a and 73b and the positioning hole portions 34a and 34b) and the positioning direction of the connector 73e and the substrate 35b (the positioning pins 73e3 and Is the same direction as the cutout portion 35b1.), The contact failure between the main body side terminal 73e2 and the metal pad 35a is less likely to occur.

Referring to FIG. 21, the positioning holes 34a and 34b of the cap part 34Y are formed at positions separated in the vertical direction so as to sandwich the ID chip 35 (information storage device). The third virtual straight line S3 that connects the centers of the two positioning holes 34a and 34b is configured to be parallel to the first virtual straight line S1 that connects the two positioning cutouts 35b1. .
Thus, since the ID chip 35 is fixed between the first positioning hole 34a (main reference) and the second positioning hole 34b (secondary reference), the connector 73e of the cap receiving portion 73 is provided. On the other hand, the position of the ID chip 35 is determined with high accuracy. Therefore, it is possible to suppress a communication failure due to the displacement of the ID chip 35 with respect to the connector 73e. In particular, the positioning direction of the cap portion 34Y in the cap receiving portion 73 (the alignment direction of the positioning pins 73a and 73b and the positioning holes 34a and 34b) and the positioning direction of the connector 73e and the substrate 35b (the positioning pins 73e3 and the notches) The positioning operation of the toner container 32Y with respect to the image forming apparatus main body 100 contributes to the direction in which the substrate 35b is easily positioned with respect to the connector 73e. As a result, the effect of preventing poor contact between the main body side terminal 73e2 and the metal pad 35a is further increased.

It should be noted that when the mounting operation of the toner container 32Y is advanced with respect to the toner container housing part 70, the procedure related to each part of the bottle receiving part 72 and the cap receiving part 73 with respect to the cap part 34Y is as follows.
First, the cap portion 34Y slides on the bottle receiving surface 72a, and thereafter, the guide rail portion 34e of the cap portion 34Y fits into the contact groove 73m of the cap receiving portion 73 and the side of the cap portion 34Y. The protrusion 34c is fitted into the side groove 73h and the groove 73r1 of the cap receiving portion 73, and the vertical and horizontal postures of the cap portion 34Y in the cap receiving portion 73 are restricted. Further, at this time, the cap portion sandwiching member 73r suppresses backlash of the cap portion 34Y immediately before being inserted into the cap receiving portion 73. Then, the first positioning hole 34a of the cap part 34Y is fitted into the main reference pin 73a of the cap receiving part 73 to perform the main reference positioning, and then the second positioning hole 34b of the cap part 34Y is the cap. The positioning of the master-slave is completed by fitting with the slave reference pin 73b of the receiving part 73. In addition, until the positioning is completed, the stopper release urging portion 72b releases the contact state between the stopper portion 34d22 of the shutter member 34d of the cap portion 34Y and the contact portion 34n5, and a shutter closing mechanism (not shown). As a result, the shutter member 34d is opened while the postures of the shutter member 34d and the cap portion 34Y in the cap receiving portion 73 are determined. The toner discharge port W opened at the cap portion 34Y and the toner supply port 73w of the cap receiving portion 73 communicate with each other. Further, the notch portion 35b1 of the ID chip 35 of the cap portion 34Y is engaged with the positioning pin 73e3 of the connector 73e of the apparatus main body 100, and the position of the ID chip 35 in the cap portion 34Y is determined. The metal pad 35a and the plurality of main body side terminals 73e2 of the connector 73e are in reliable contact with each other. Thus, the setting of the cap part 34Y (toner container 32Y) in the cap receiving part 73 (toner container housing part 70) is completed. At this time, the gear 33c of the container main body 33Y meshes with the drive gear 81 of the apparatus main body 100.
On the other hand, when the toner container 32Y is taken out (detached) from the toner container housing part 70 (cap receiving part 73), the operation is performed in the reverse order of the above-described procedure at the time of mounting.

As described above, in the image forming apparatus according to the first embodiment, the user moves the toner container 32Y in the longitudinal direction while holding the holding portion 33d (except for the opening / closing operation of the main body cover). In conjunction with this operation, the opening and closing operation of the toner discharge port W by the shutter member 34d is also performed, and the mounting operation and the detaching operation of the toner container 32Y are completed.
Further, in the toner container 32Y of the first embodiment, a toner discharge port W having a relatively large opening area is disposed downward in the vertical direction, and toner is discharged directly from the toner discharge port W by its own weight fall. Can be done.
The toner container 32Y is not mounted from above the toner container housing part 70 (device main body 100), but is attached and detached from the front surface of the toner container housing part 70 (device main body 100). The degree of freedom of the layout above the portion 70 is increased. For example, even when a scanner (original reading unit) is disposed directly above the toner replenishing device, the operability and workability in attaching and detaching the toner container 32Y do not deteriorate.
Further, since the toner container 32Y is installed in the apparatus main body 100 with the longitudinal direction as the horizontal direction, the toner capacity of the toner container 32Y is increased without affecting the layout in the height direction of the entire image forming apparatus 100. Thus, the replacement frequency can be reduced.

  As described above, in the first embodiment, the contact-type ID chip 35 (information storage device) is in the moving direction when the metal pad 35a (terminal) approaches and comes into contact with the main body side terminal 73e2. Are held by a holding member 34k (holding portion) so as to be able to move on a substantially orthogonal virtual plane. Accordingly, even when the contact type ID chip 35 (information storage device) is installed in the toner container 32Y (detachable device) that is detachably installed on the image forming apparatus main body 100, the image forming apparatus. Contact failure due to poor positioning with the main body side terminal 73e2 of the connector 73e of the main body 100 is less likely to occur.

Embodiment 2. FIG.
A second embodiment of the present invention will be described in detail with reference to FIGS.
FIG. 31 is a schematic cross-sectional view showing the toner container 232Y in the second embodiment. FIG. 32 is a rear view showing the cap portion 234Y in the toner container 232Y. FIG. 33 is a perspective view showing a holding lid 234k8 fitted to the holding member 234k.
The toner container 232Y according to the second embodiment is different from that of the first embodiment in the configuration of the holding member 234k in the holding mechanism that holds the information storage device.

Similarly to the first embodiment, the toner container 232Y in the second embodiment also includes a container main body 33Y and a cap portion 234Y. An ID chip 35 as an information storage device is detachably installed on the cap portion 234Y.
Here, the cap member 234Y in the second embodiment is integrally formed with a holding member 234k formed with an opening 34k2 in which a part of the ID chip 35 (the metal pad 35a and the notch 35b1) is exposed. Is formed.
The ID chip 35 is inserted from the inside of the cap portion 234Y in the direction of the white arrow in FIG. 31 and set at the position of the holding member 234k. Then, in a state where the ID chip 35 is set at the position of the holding member 234k, the holding lid 234k8 is inserted in the direction of the white arrow in FIG. 31 from the inside of the cap portion 234Y and is fitted to the holding member 234k (FIG. 32). State.)

The holding lid 234k8 is provided with a pedestal 234q for fitting to the holding member 134k so as not to contact the substrate 35b.
In addition, the holding lid 234k8 is installed so as to be in close contact with the inner wall of the cap portion 234Y so that the toner in the toner container 232Y does not leak and adhere to the ID chip 35.
Also in the second embodiment, the ID chip 35 (substrate 35b) is held by the holding member 234k (and the holding lid 234k8) so that it can move in the XZ plane.

  As described above, also in the second embodiment, as in the first embodiment, the contact type ID chip 35 (information storage device) has the metal pad 35a (terminal) with respect to the main body side terminal 73e2. It is held by a holding member 234k (holding portion) so that it can move on a virtual plane that is substantially orthogonal to the moving direction when approaching and contacting. Accordingly, even when the contact type ID chip 35 (information storage device) is installed in the toner container 232Y (detachable device) that is detachably installed on the image forming apparatus main body 100, the image forming apparatus. Contact failure due to poor positioning with the main body side terminal 73e2 of the connector 73e of the main body 100 is less likely to occur.

Embodiment 3 FIG.
A third embodiment of the present invention will be described in detail with reference to FIG.
FIG. 34 is a schematic diagram showing a state where the information storage device 35 of the toner container 332Y in the third embodiment is set in the connector 73e of the cap receiving portion 73, and corresponds to FIG. 27 in the first embodiment. It is.
The third embodiment is different from the first embodiment in that the cushion material 334k10 is installed inside the holding member 34k and the configuration of the wall portion 373g in the cap receiving portion 373.

  The toner container 332Y according to the third embodiment is also composed of a container main body 33Y and a cap portion 34Y, as in the above-described embodiments. An ID chip 35 as an information storage device is detachably installed on the cap portion 34Y. Further, the ID chip 35 is held inside the holding member 34k so as to be movable in the XZ plane.

  Here, in the third embodiment, the cushion material 334k10 is provided between the inner wall (second facing portion 34k5) of the holding member 34k and the substrate 35b. The cushion material 334k10 is made of an elastic material such as polyurethane foam, and a low friction material is adhered to a portion facing the substrate 35b. Thereby, the damage which arises in the board | substrate 35b when the positioning pin 73e3 engages with the notch part 35b1 can be reduced, without preventing the movement in the XZ plane of ID chip (board | substrate 35b).

  Moreover, in this Embodiment 3, the wall part 373g in the cap receiving part 373 is installed so that the four sides of the connector 73g may be enclosed. And corresponding to this, the cap part 34Y is provided with the recessed part for avoiding interference with the wall part 373g. Thus, by providing the wall portion 373g, even if the toner scatters from the vicinity of the toner outlet W of the toner container 332Y to the outside, the scattered toner hardly adheres directly to the connector 73e or the ID chip 35. Become. Therefore, it is possible to suppress contact failure (communication failure) between the connector 73e (main body side terminal 73e2) and the ID chip 35 (metal pad 35a) due to scattered toner.

  As described above, also in the third embodiment, the contact type ID chip 35 (information storage device) has the metal pad 35a (terminal) with respect to the main body side terminal 73e2 in the same manner as the above embodiments. It is held by a holding member 34k (holding portion) so that it can move on a virtual plane that is substantially orthogonal to the moving direction when approaching and contacting. Thus, even when the contact type ID chip 35 (information storage device) is installed in the toner container 332Y (detachable device) that is detachably installed on the image forming apparatus main body 100, the image forming apparatus. Contact failure due to poor positioning with the main body side terminal 73e2 of the connector 73e of the main body 100 is less likely to occur.

Embodiment 4 FIG.
A fourth embodiment of the present invention will be described in detail with reference to FIG.
FIG. 35 is a three-sided view showing the substrate 435b of the information storage device 435 in the fourth embodiment, and corresponds to FIG. 14 in the first embodiment.

  The toner container (432Y) in the fourth embodiment is also composed of a container main body 33Y and a cap portion 34Y, as in the above-described embodiments. An ID chip 435 as an information storage device is detachably installed on the cap part 34Y. Further, the ID chip 435 is held inside the holding member 34k so as to be movable in the XZ plane.

Here, positioning holes 435b11 and 435b12 are provided in the substrate 435b of the ID chip 435 in the fourth embodiment, instead of the positioning notches 35b1 in the respective embodiments. As the toner container (432Y) is mounted, the positioning holes 435b11 and 435b12 are engaged with the positioning pins 73e3 of the connector 73e while the substrate 435b freely moves in the XZ plane. . Specifically, the positioning pin 73e3 comes into contact with the edge (or the inner surface) of the holes 435b11 and 435b12, and the movement of the substrate 435b is restricted. This makes it difficult for poor contact due to poor positioning between the plurality of metal pads 35a and the main body side terminal 73e2 of the connector 73e.
In the fourth embodiment, the substrate 435b is positioned below in the holding member 34k by the weight of the substrate 435b until just before the positioning holes 435b11 and 435b12 engage with the positioning pin 73e3. Considering this, a circular hole 435b11 is formed below the substrate 435b, and an elongated hole 435b12 is formed above the substrate 435b. When the lower hole 435b11 is picked up by the positioning pin 73e3, the substrate 435b is lifted, and the positioning pin 73e3 is smoothly inserted into the other long hole (hole 435b12). If the lower hole is a long hole and the upper hole is a round hole, the substrate 435b cannot be lifted by the positioning pin 73e3, and the positioning pin 73e3 is difficult to insert into the upper round hole. There is a fear.

  In the fourth embodiment, two positioning holes 435b11 and 435b12 are formed in the substrate 35b of the ID chip 35. On the other hand, in the substrate 435b of the ID chip 435, one is used as a positioning hole 435b11 (or 435b12) and the other is used as a positioning notch 35b1 (used in the above embodiments). ). Even in such a case, the same effect as in the fourth embodiment can be obtained.

  As described above, also in the fourth embodiment, the contact type ID chip 435 (information storage device) has the metal pad 35a (terminal) with respect to the main body side terminal 73e2 in the same manner as the above embodiments. It is held by a holding member 34k (holding portion) so that it can move on a virtual plane that is substantially orthogonal to the moving direction when approaching and contacting. Thus, even when the contact type ID chip 435 (information storage device) is installed in a toner container (detachable device) that is detachably installed on the image forming apparatus body 100, the image forming apparatus body. Contact failure due to poor positioning with the main body side terminal 73e2 of the 100 connector 73e is less likely to occur.

Embodiment 5 FIG.
A fifth embodiment of the present invention will be described in detail with reference to FIGS.
FIG. 36 is a three-sided view showing the substrate of the information storage device 535 in the fifth embodiment, corresponding to FIG. 29 in the first embodiment. FIG. 37 is a perspective view showing the information storage device 535, the holding member 534k (534k25), and the connector 573e, and is a perspective view showing the relative positional relationship between the three members 534k (534k25), 535, and 573e. FIG. 38 is a perspective view showing a state where the information storage device 535 is engaged with the connector 573e. FIG. 39 is a circuit diagram showing an electrical circuit of the information storage device 535 and an electrical circuit of the connector 573e. FIG. 40A is a front view showing a state in which the information storage device 535 is held by the connector 573e. FIG. 40B shows the information storage device 535 rotating around the positioning hole 535b21. It is a front view which shows a state. FIG. 41 is a diagram showing the information storage device 535 in a state in which the probe 400 is in contact with the inspection process at the time of factory manufacture.
In the fifth embodiment, only one positioning hole 535b21 is formed in the substrate 535b of the information storage device 535, and a plurality of rectangular metal pads 35a1, 35a2, positioning holes 535b21, The point arrange | positioned between 35a3 (metal plate) differs from the thing of said each embodiment.

Referring to FIG. 36, an ID chip 535 serving as an information storage device according to the fifth embodiment has a positioning hole 535b21 formed at a position vertically above the center of gravity of substrate 535b. In addition, a metal terminal 535d for grounding (earth) is provided on the inner diameter portion and the periphery of the hole portion 535b21. In the fifth embodiment, the metal terminal 535d formed on the surface of the substrate 535b is formed such that two projecting portions 535d1 extend in the horizontal direction with respect to the annular portion.
Further, with respect to the positioning hole 535b21, one rectangular metal pad 35a1 is installed at a position above the vertical direction, and two rectangular metal pads 35a2 and 35a3 are installed at a position below the vertical direction. Has been.
Further, on the back side of the substrate 535b (the side facing the cap portion 34Y), a protective member 535e made of a resin material such as a hemispherical epoxy and covering and protecting the information storage portion is provided. In the fifth embodiment, although it depends on the shape of the substrate 535b and the configuration / arrangement of the back surface of the protective member 535e, etc., it is a component that has the largest weight on the back surface because it may have an information storage unit such as an IC inside. However, by arranging the hole 535b21 above the protective member 535e, the positional relationship that the hole 535b21 is vertically above the center of gravity of the ID chip 535 described above is realized. Specifically, referring to FIG. 40A, in ID chip 535 (information storage device) according to the fifth embodiment, the center position of positioning hole 535b21 is a distance Za from the center of gravity of ID chip 535. It is formed to be only upward.

Referring to FIG. 37, the connector 573e has a connector main body 573e21 that is a resin-made hollow box, and the connector main body 573e21 has a positioning pin 573e23 (positioning with a single hollow cylinder and a tapered shape at the tip). Projections) are provided so as to stand in the horizontal direction. The positioning pin 573e23 is provided with a grounding body side terminal 573e25 (ground terminal). The grounding main body side terminal 573e25 is a plate-shaped (or linear) metal member, a part of which is housed in a hollow portion of a positioning pin 573e23 formed integrally with the connector main body 73e21, and its curved portion. Is exposed from a slit-like opening formed in a part of the peripheral surface of the hollow cylinder and protrudes from the outer peripheral surface of the cylinder. Further, with respect to the positioning pin 573e23 (main body terminal 573e25 for grounding), one main body side terminal 73e2 is installed at a position above the vertical direction, and two main body side terminals 73e2 are installed at a position below the vertical direction. Has been. These main body side terminals 73e2 are plate-shaped (or linear) metal members, and are formed in substantially the same manner as those of the above-described embodiments except that the installation positions are different.
Further, below the connector main body 573e21, on both sides of the positioning pin 573e23, a pair of ribs are formed so that the taper surfaces inside the tips are symmetrical with each other. In addition, a shake preventing member 573e24 is provided as a pair of restricting members that are opposed to a position vertically below the center of the hole 535b21.

Further, the holding member 534k (holding portion) is fixed to the toner container (532Y) and is located between the connector 573e and the ID chip 535, as in the above embodiments. Its shape is almost the same as that of the above-described embodiments, and its function (function to hold the ID chip 35 movably) is also the same. Referring to FIG. 37, in the holding member 534k in the fifth embodiment, the first facing portion 534k24 is configured to be line-symmetric with respect to the vertical axis, and the hole portion 535e21 is formed from two corners at the upper end of the ID chip 535. It is formed so as to cover the area up to both sides. Further, the holding member 534k is formed so as to cover the lower side of the lowermost metal pad 35a3 of the substrate 535b also in the lower part, and the ID chip 535 is prevented from dropping from the holding member 534k by these configurations. .
Further, in the holding member 534k, most of the first facing portion 534k24 including an area facing the four main body side terminals 73e2 and 573e25 of the connector 573e is an opening. In particular, the holding member 534k is a convex opening 534k22 that is open to a portion corresponding to the pair of shake preventing members 73e24. When the toner container 532Y is mounted, the shake preventing member 573e24 (a pair of regulating members) also enters the holding member 534k through the opening 534k22 following the intrusion of the positioning pin 573e23 into the opening 534k22.
The flat plate-like second facing portion 534k25 facing the back side of the ID chip 535 (on the side of the protective member 535e) is fixed to the holding member 534k by bonding or a snap fit (not shown). Similar to the first opposing portion 534k24, the second opposing portion 534k25 has a convex opening 534k26 and can avoid interference with the protective member 535e and the intrusion prevention member 573e24. On the other hand, the ID chip 535 is pushed when the positioning pin 573e23 is inserted into the hole 535b21 of the ID chip 535, but the second opposing portion 534k25 supports the substrate 535b from the back, so that the terminal The contact state between each other can be maintained.

FIG. 38 shows that when the toner container 532Y according to the fifth embodiment is mounted on the apparatus main body 100, the positioning of the connector 573e on the apparatus main body 100 side and the ID chip 535 is completed, and the main body side terminals 73e2, 573e25 and the above-described metal are shown. It is a schematic perspective view which shows the state which pad 35a1-35a3 and the ground terminal 535d connected. In FIG. 38, the illustration of the holding member 534k (534k25) and the metal pads 35a1 to 35a3 between the connector 573e and the ID chip 535 is omitted for easy understanding.
Of the series of mounting operations of the toner container 532Y, the main reference and sub reference positioning holes 34a and 34b of the cap portion 534Y are fitted to the main reference and sub reference positioning pins 73a and 73b of the cap receiving portion 73. The operation until the cap portion 534Y is positioned is the same as the mounting operation of the first embodiment. After that, after the position of the cap portion 534Y is determined, the hole portion 535b21 of the ID chip 535 is fitted to the positioning pin 573e23 so as to be picked up by the taper at the tip of the positioning pin 573e23 of the connector 573e. The position in the direction and the vertical direction are determined simultaneously. Furthermore, as shown in FIG. 40 (A), a vibration preventing member 573e24 (a pair of ribs of a connector 573e2) is formed on the lower edge on both the left and right sides of the substrate 535b and below the center of the hole 535b21. Intrusion member). At this time, even if the posture of the ID chip is shifted as shown in FIG. 40B, when the tapered surface of the rib tip comes into contact with the edge, the posture is made vertical by the action of the center of gravity. Then, the substrate 535b is rotated, and the deviation of the posture in the rotation direction (the rotation in the direction of the double arrow shown in FIG. 40B) is corrected (the state shown in FIG. 40A is set). Thereby, the positioning of the ID chip 535 is completed. At this time, a part of the ground terminal 535d of the ID chip 535 (corresponding to the inner diameter part of the hole 535b21) comes into contact with the grounding body side terminal 573e25 of the positioning pin 573e23 shown in FIG. The ID chip 535 is grounded (conducted). Further, after the grounding, as shown in FIG. 39A, the three metal pads 35a (35a1, 35a2, 35a3) of the ID chip 535 are also in contact with the three main body side terminals 73e2 of the connector 573e. Thus, information can be transmitted between the ID chip 535 and the main body side connector 573e (device main body 100).

As described above, in the fifth embodiment, a high-accuracy positioning mechanism is realized with an inexpensive configuration by adding various ideas (1) to (5) below.
(1) One positioning hole 535b21 is provided. As a result, the processing cost of the substrate 535b can be reduced.
(2) The main body side terminal 573e25 for grounding is integrally installed on the side peripheral surface of the positioning pin 573e23. Thereby, the distance between the positioning pin 573e23 and the main body side terminal 573e25 can be substantially zero, and the positional accuracy of the ground terminal 535d with respect to the main body side terminal 573e25 can be improved.
(3) In the mounting completion state of FIG. 38, the hole portion 535b21 and the hole portion 535b21 are aligned so that the hole center of the positioning hole portion 535b21 coincides with the line connecting the curved portions (contact portions) of the three main body side terminals 73e2 on the connector 573e side. The arrangement relationship with the curved portion of the main body side terminal 573e2 is adjusted. As a result, the horizontal distance from the hole 535b21, which is the positioning portion, to the contact portion can be reduced to near 0 mm. As a result, the positional accuracy when the three metal pads 35a1, 35a2, 35a3 and the main body side terminal 73e2 come into contact with each other is improved.
(4) The position of the positioning hole 535b21 is arranged in any one of the plurality of gaps generated when the plurality of metal pads 35a1, 35a2, and 35a3 are arranged. As a result, the metal pad 35a3 located farthest from the center of the positioning hole 535b21 as compared with the case where the hole is arranged above or below the arrangement of the plurality of metal pads 35a1, 35a2, 35a3. Distance (which corresponds to the arm length of the pendulum). Specifically, when the hole is arranged outside the arrangement of the metal pads 35a1, 35a2, and 35a3, the arm length is the distance of three metal pads from the center of the hole. The length can be as long as two metal pads. By shortening the arm length of the deflection, even if the parallelism of the metal pad 35a3 at the farthest position with respect to the main body side terminal 73e2 is deviated due to mass production variation or the like, the deviation can be minimized. .
(5) When the toner container is stored as a single item, foreign matter may enter the holding member 534k and be sandwiched between the ID chip 535 and the facing portions 534k24, 534k25, and the position may be shifted. In order to deal with such a problem, in the fifth embodiment, the positional relationship is devised so that the hole 535b21 of the ID chip 535 is above the center of gravity in the vertical direction. As a result, when the shake preventing member 573e24 composed of a pair of ribs enters vertically below the hole 535b21 which is the rotation center, the center of gravity is triggered by contact with the taper surface of the shake preventing member 573e24 (rib). With this action, the posture can be rotated along the vertical direction (the positional deviation can be regulated to correct the posture). As a result, even if there is one positioning hole 535b21, the positional accuracy of the plurality of metal pads 35a1, 35a2, and 35a3 with respect to the plurality of body-side terminals 573e2 can be enhanced at the same time.
As described above, as described in (1) to (5), each of the five devices exerts their respective effects, and adopts an inexpensive configuration that minimizes the area of the metal pad 35a. In addition, the positioning accuracy of the plurality of terminals 35a and 535d on the ID chip 535 side including the ground terminal and the plurality of main body side terminals 573e2 and 573e25 can be made extremely high.

Further, the device and effects of the fifth embodiment will be described separately from those described above.
First, each of the metal pads 35a1, 35a2, and 35a3 will be described in detail. A clock signal for communication control is input to the uppermost metal pad 35a1. A low-cost serial communication method is adopted because of sequential communication, I2C (Inter-Integrated Circuit) is used as a serial bus, and a serial clock (SCL) signal is input while connected to the main unit connector. Form a line. Although the metal pad 35a1 corresponds to a terminal on the clock signal input direction side, the clock signal has a one-way signal flow, so that the ID chip 535 can be destroyed by a short circuit with Vcc (power supply, metal pad 35a3) described later. Is expected to be higher than other terminals. Therefore, in order to avoid destruction of the ID chip 535, it is arranged at a location away from Vcc. This is because the possibility of breakage is low even if it is short-circuited to GND (ground terminal 535d).
The metal pad 35a2 also adopts a serial communication system, adopts I2C as a serial bus, and forms a signal line through which serial data (SDA) is input / output in a state of being connected to the main body side connector. Since this pad is bidirectional for input and output, the possibility of destruction of the ID chip 535 due to a short circuit is less than that of the metal pad 35a1 for unidirectional input.
The metal pad 35a3 is a power input unit (Vcc), and a voltage of 5V or 3.3V is input in a state where it is connected to the main body side connector. A serial data input terminal (metal pad 35a2) is sandwiched between the GND (ground terminal 535d) and the serial clock input terminal (metal pad 35a1) in order to reduce the risk of failure of the entire device, such as a short circuit between the power supply and GND. Is arranged in. As shown in FIG. 36, the metal pad 35a3 which is Vcc overlaps with the protection member 535e on the back side of the ID chip via the substrate 535b, and is close to the IC drive circuit in the protection member 535e. As a result, the power supply line can also be shortened and thickened, and power supply operation can be stabilized (= noise malfunctions reduced).
Next, I will describe some ideas regarding grounding. In the mounting operation of the toner container 532Y, after the ground terminal 535d of the ID chip 535 contacts the main body terminal 573e25 for grounding of the positioning pin 573e23 (connector 573e), the three metal pads 35a1, 35a2, and 35a3 of the ID chip 535 are moved. The contact is started with the three main body side terminals 73e2 of the connector 573e. In other words, in the detachment operation of the toner container 532Y, after the contact of the three metal pads 35a1, 35a2, and 35a3 of the ID chip 535 with the three main body side terminals 73e2 of the connector 73e is released, the ground terminal 535d of the ID chip 535 is released. Is configured to be released (separated) from the main body side terminal 573e25 for grounding of the positioning pin 573e23 (connector 573e). Specifically, referring to FIG. 39A, in connector 573e, the contact start position of grounding body side terminal 573e25 is closer to the ID chip 535 side than three body side terminals 73e2. It is formed as follows.
With such a configuration, in the mounting operation of the toner container 532Y, the connection between the metal pads 35a1, 35a2, 35a3 and the main body side terminal 73e2 is started while the ID chip 535 is always grounded, and the toner container 532Y is connected. In the detachment operation, separation (contact release) between the metal pads 35a1, 35a2, 35a3 and the main body side terminal 73e2 is started in a state where the ID chip 535 is always grounded. Therefore, the electric circuit on the ID chip 535 side is prevented from being electrically floated without being grounded, and the ID chip 535 is less likely to be electrically damaged.
Specifically, when the electric circuit on the ID chip 535 side is in an electrically floating state without being grounded, the electric circuit is in a state of being grounded with a very large impedance, and the metal pad 535a and the body side terminal 573e2. When static electricity generated at the time of contact with or away from the battery flows into the electric circuit, a high voltage equivalent to the current multiplied by the impedance is generated. This high voltage causes dielectric breakdown inside the IC in the ID chip 535, and the IC is broken. As shown in FIG. 39B, such a problem is caused in the connector 573e where the contact start positions of the three main body side terminals 73e2 and the grounding main body side terminal 573e25 with respect to the ID chip 535 are formed at the same position. It tends to occur when
On the other hand, in the fifth embodiment, the bending of the main body side terminal 573e25 exposed from the slit-like opening of the positioning pin 573e23 rather than the bending portion that is the most protruding portion on the ID chip 535 side in the main body side terminal 73e2. The part is arranged so as to be closer to the ID chip 535. As a result, the grounding of the circuit at the time of contact is performed first, and the grounding of the circuit at the time of separation is the last, so the impedance is always theoretically zero, and even if static electricity flows into the electrical circuit, the breakdown inside the IC is prevented. Can be prevented.

Further, in the ID chip 535 (information storage device) according to the fifth embodiment, as described above with reference to FIG. 36, two protrusions 535d1 are provided on a part of the outer periphery of the ground terminal 535d.
In this manner, by providing the protrusion 535d1 on the front surface of the substrate 535b of the ID chip 535, in the inspection process at the time of manufacturing at the factory (this is a process for inspecting the quality / defectiveness of the ID chip 535), it is for current application inspection. The contact operation of the probe can be facilitated. Specifically, as shown in FIG. 41, the tip portions of the plurality of probes 401 of the current inspection apparatus 400 are respectively attached to the metal pad 35a and the ground terminal 535d of the ID chip 535 placed on the inspection table from above. Press. At this time, the projecting portion 535d1 of the ground terminal 535d has a sufficient area for the tip portion of the probe 401 to come into contact with it, so that it is possible to prevent a poor conduction test due to poor contact of the probe 401. Moreover, since the tip portion of the probe 401 is brought into contact with the ground terminal 535d (protrusion portion 535d1) from above, an energization test is performed, so compared to the case where the probe 401 is inserted into the hole 535b21 and the energization test is performed. In addition to improving the resistance of the probe 401 itself that is repeatedly used for each inspection, it is possible to prevent a problem that the hole 535b21 of the ID chip 535 is worn due to the current inspection.

  In the surplus space extending in a wedge shape between the ring of the ground terminal 535d and the rectangular metal pad 35a, the protrusion 535d1 has a horizontal boundary (boundary line) in contact with the outer periphery of the ring, The pads 35a1, 35a2, and 35a3 are arranged in parallel with each other. Accordingly, the protrusion 535d1 does not protrude in the vertical direction, and the protrusion (protrusion in the horizontal direction) of the protrusion 535d1 to the left and right sliding regions of the board 535b sliding with the first facing portion 534k24 is suppressed. be able to. As a result, without increasing the size of the substrate 535b, it is possible to increase the number of substrates 535b to be taken from a substrate material whose standard dimensions are determined in manufacturing, and to increase the cost of the ID chip 535. Can be suppressed.

  As described above, also in the fifth embodiment, the contact type ID chip 535 (information storage device) has the metal pads 35a1, 35a2, 35a3 with respect to the main body side terminal 573e2, as in the above embodiments. It is held by the holding member 534k (holding portion) so that it can move on a virtual plane that is substantially orthogonal to the moving direction when the (terminal) approaches and comes into contact. Thus, even when the contact-type ID chip 535 (information storage device) is installed in the toner container 532Y (detachable device) that is detachably installed on the image forming apparatus main body 100, the image forming apparatus. Contact failure due to poor positioning of the connector 573e of the main body 100 with the main body side terminal 573e2 is less likely to occur.

  Furthermore, in the fifth embodiment, a contact type ID chip 535 (information storage device) is installed in a toner container 532Y (detachable device) that is detachably installed on the image forming apparatus main body 100. Even in this case, the grounding body side terminal 573e25 formed on the positioning pin 573e23 (protrusion) of the connector 573e (image forming apparatus body 100) is inserted into one hole 535b21 formed on the substrate 535b of the ID chip 535. Since the engaging ground terminal 535d is formed, the ID chip 535 is less likely to be electrically damaged.

Embodiment 6 FIG.
The sixth embodiment of the present invention will be described in detail with reference to FIGS.
FIG. 42 is a perspective view showing the toner container 632Y according to the sixth embodiment. In particular, FIG. 42A is an exploded view showing a state before the ID chip 535 described in the fifth embodiment is mounted. FIG. 42B is a diagram showing a state where the ID chip 535 is mounted. FIG. 43 is a front view showing the toner container 632Y in a state before the face plate 634p is installed, and corresponds to FIG. 21 in the first embodiment. FIG. 44 is a cross-sectional view showing a main part of the toner container 632Y in a state where the ID chip 535 and the face plate 634p are installed. Further, FIG. 45 is a diagram showing a state where the ID chip 535 is inserted into the connector 573e.
In the sixth embodiment, an ID chip 535 as an information storage device is the same as that of the fifth embodiment, and the ID chip 535 is loosely inserted into a recess provided in the cap portion 634Y and can be moved by a face plate 634p. Unlike the fifth embodiment, the other configuration is the same as that of the fifth embodiment.

  The toner container 632Y according to the sixth embodiment is also composed of a container main body 33Y and a cap portion 634Y, as in the above-described embodiments. An ID chip 535 as an information storage device is detachably installed on the cap unit 634Y.

Here, in the sixth embodiment, referring to FIG. 42, the ID chip 535 is not installed in the cap portion 534Y in a state of being loosely inserted into the holding member 534k, but the ID chip 535 is The face plate 634p for preventing the drop-off is screwed to the cap portion 634Y in a state where it is loosely inserted into the concave portion (the pedestal portion 634q is formed) formed in the cap portion 634Y.
Specifically, referring to FIGS. 42A and 43, a recess for holding ID chip 535 so that it can move in the XZ plane is formed on the end surface of cap portion 634Y. A pedestal portion 634q that is in surface contact with only a part of the ID chip 535 is formed in the recess. Then, a face plate 634p for preventing the ID chip 535 from dropping from the recess is installed in a state where the ID chip 535 is loosely inserted in the recess of the cap portion 634Y. 42B, 43, and 44, this face plate 634p has metal pads 35a1, 35a2, and 35a3 of ID chip 535 and positioning holes formed in the same manner as in the fifth embodiment. With the portion 535b21 (earth terminal 535d) and the like exposed, screws are fastened so as to be able to contact a part of the substrate 35b of the ID chip 35.

More specifically, the cap portion 634Y has a recess, and a positioning pin 634s1 for positioning the face plate 634p is formed on the right side toward the recess, and a screw hole for screwing the face plate 634p on the left side is formed. 634s11 is formed. On the other hand, in the face plate 634p, a positioning hole 634p1 is formed at a position corresponding to the positioning pin 634s1, and a hole 634p2 through which the screw 680 passes is formed at a position corresponding to the screw hole 634s11. Further, below the face plate 634p, an abutting portion 634p3 that abuts on the outer peripheral edge of the second positioning hole portion 34b and functions as a detent is formed. The position of the face plate 634p is determined with respect to the cap portion 634Y by the positioning hole 634p1 and the contact portion 634p3 for preventing rotation. Then, the screw 680 is screwed into the screw hole 634s11 formed in the cap portion 634Y via the hole portion 634p2 formed in the face plate 634p, and the face plate 634p is fixed to the cap portion 634Y. As a result, the ID chip 535 is held by the cap unit 634Y so that the ID chip 535 can move in the XZ plane without falling off the cap unit 634Y. Referring to FIG. 45, as in the case of the fifth embodiment, the ID is applied to the positioning pin 573e23 (the main body side terminal 573e25 for grounding) of the connector 573e of the apparatus main body 100 in accordance with the mounting operation of the toner container 632Y. The positioning hole 535b21 (ground terminal 535d) of the chip 535 is engaged, and then the main body side terminal 73e2 of the connector 573e contacts the metal pads 35a1, 35a2, 35a3 of the ID chip 535, and the connector 73e and the ID chip The electrical connection with 35 is completed. At this time, since the ID chip 535 is held movably in the XZ plane in the cap portion 634Y of the toner container 632Y, the main body side terminal 73e2 of the connector 573e of the apparatus main body 100 is the same as in the above embodiments. , 573e25 and poor contact due to poor positioning are less likely to occur. In a normal state, the ID chip 535 is sunk under the concave portion of the cap portion 534Y due to gravity, and the hole portion of the ID chip 535 is the leftmost of the three ID chips 535 illustrated in FIG. The center position of 535b21 is shifted downward with respect to the axial center position of the positioning pin 573e23.
Then, when the mounting operation of the toner container 632Y is started and the ID chip 545 and the positioning pin 573e23 come into contact with each other, the ID chip 535 moves upward (Z direction) so that the hole 535b21 follows the tip tapered portion of the positioning pin 573e23. Then, the hole 535b21 is fitted into the positioning pin 573e23, and the main body side terminal 573e2 finally comes into contact with the metal pads 35a1, 35a2, and 35a3.

Here, in the sixth embodiment, the face plate 634p is fixed to the cap portion 34Y with screws 680 (screw fastening).
On the other hand, as shown in FIG. 46, the face plate 734p can be fixed to the cap portion 734Y by snap fitting. Specifically, as shown in FIG. 46 (A), a plurality of engaging portions 734p2 for snap fitting are formed on the outer peripheral portion of the face plate 734p, and the snap fitting is stopped at the position of the cap portion 734Y corresponding thereto. An engaged portion 734s2 is formed. As shown in FIG. 46B, the face plate 734p is snap-fitted to the cap portion 734Y in a state where the ID chip 535 is loosely inserted into the concave portion of the cap portion 734Y. More specifically, the engaging portion 734p2 of the face plate 734p is engaged with the engaged portion 734s2 of the cap portion 734Y while the hole 734p3 formed in the face plate 734p is aligned with the positioning boss portion 734s3 formed in the cap portion 734Y. Then, the face plate 734p is positioned and fixed to the cap portion 734Y. Even in such a configuration, the same effect as in the sixth embodiment can be obtained.

In the sixth embodiment, since the face plate 634p (or the face plate 734p shown in FIG. 46) can be replaced again after the assembly, the toner container and the face plate are first manufactured by a foreign partner company. The toner container can be manufactured by a procedure of importing the toner chip and inputting the toner information by assembling the ID chip 535 purchased from another company before and after the step of filling the toner container with the toner in Japan. Thereby, the efficiency of the manufacturing process of the toner container can be improved.
Also, in the recycling process of collecting used toner containers from the market and refilling the toner after cleaning it, the ID chip 535 is replaced or the information is rewritten by removing the ID chip 35 from the toner container once. It can be performed by the procedure of attaching to the cap part again. Thereby, the efficiency of the reuse process of the toner container can be improved.
However, referring to FIG. 47C (a cross-sectional view showing the cap portion 834Y with the ID chip 535 mounted), it is not necessary to remove the ID chip 535, and the face plate 834p and the cap portion 834Y When it is desired to keep the assembly strength strong, only the positioning boss 734s3 (see FIG. 46) can be used as the cap portion without providing the above-described screw fastening shape or snap fit shape. It can also be provided. Then, after attaching the ID chip 535 and the face plate 834p to the cap portion 834Y, the tip of the positioning boss 734s3 is melted by heat to fix the face plate 834p to the cap portion 834Y, or an adhesive is provided between the face plate 834p and the cap portion 834Y.

Since the engaging ground terminal 535d is formed, the ID chip 535 is less likely to be electrically damaged.

Embodiment 11 FIG.
56 to 58, the tenth embodiment of the present invention will be described in detail.
FIG. 56 is a perspective view showing connector 1473e of the image forming apparatus in the tenth embodiment, and corresponds to FIG. 16 in the first embodiment. 57 is a three-sided view showing an ID chip 1435 as an information storage device that contacts the connector 1473e of FIG. 56, and corresponds to FIG. 29 in the first embodiment. FIG. 58 is a three-side view showing an ID chip 1535 as an information storage device according to another embodiment, and corresponds to FIG. 35 in the fourth embodiment.
In the eleventh embodiment, a grounding body side terminal 1473e5 is provided on the positioning pin 1473e3 of the connector 1473e, and a grounding metal terminal that contacts the grounding body side terminal 1473e5 is provided on the ID chips 1435 and 1535. 1435d and 1535d (ground terminals) are different from those of the first and fourth embodiments.

Referring to FIG. 56, the image forming apparatus according to the eleventh embodiment has a connector main body 1473e1, four main body side terminals 1473e2, and two positioning pins 1473e3 (positioning pins 1473e3) as in the first embodiment. A connector 1473e configured by a projection), a snap fit 1473e4, and the like is provided.
Here, the connector 1473e according to the eleventh embodiment has a grounding body side terminal 1473e5 (ground terminal) on the inner side of the positioning pin 1473e3 (a portion that contacts the notch 1435b1 and the hole 1535b11 of the ID chip 1435). ) Is installed.

On the other hand, referring to FIG. 57, in ID chip 1435 (substrate 1435b) in the eleventh embodiment, ground metal terminal 1435d (ground terminal) is installed on the inner diameter portion and the periphery of two cutout portions 1435b1. ing.
With such a configuration, after the ground terminal 1435d of the ID chip 1435 comes into contact with the grounding main body side terminal 1473e5 (refer to FIG. 56) of the positioning pin 1473e3 (connector 1473e) in the toner container mounting operation. The four metal pads 35a of the chip 1435 start to contact the four main body side terminals 1473e2 of the connector 1473e. In other words, in the operation of removing the toner container, after the contact of the four metal pads 35a of the ID chip 1435 to the four main body side terminals 1473e2 of the connector 1473e is released, the ground terminal 1435d of the ID chip 1435 is moved to the positioning pin 1473e3 ( The contact is released (separated) from the main body side terminal 1473e5 for grounding of the connector 1473e). Specifically, the connector 1473e is formed so that the contact start position of the grounding main body side terminal 1473e5 is closer to the ID chip 1435 side than the four main body side terminals 1473e2.
With such a configuration, the connection between the metal pad 35a and the main body side terminal 1473e2 is started while the ID chip 1435 is always grounded in the toner container mounting operation, and the ID is always in the toner container detaching operation. The separation (contact release) between the metal pad 35a and the main body side terminal 1473e2 is started in a state where the chip 1435 is grounded. Therefore, the electric circuit on the ID chip 1435 side is prevented from being electrically floated without being grounded, and the ID chip 1435 is less likely to be electrically damaged.

Further, similarly to the relationship between the ID chip in Embodiment 1 and the ID chip in Embodiment 4, the ID chip 1435 shown in FIG. 57 can be replaced with the ID chip 1535 shown in FIG.
Specifically, referring to FIG. 58, grounding metal terminal 1535d (ground terminal) is installed in ID chip 1535 at the inner diameter portion and the periphery of one positioning hole portion 1535b11.
With such a configuration, after the ground terminal 1535d of the ID chip 1535 comes into contact with the grounding main body side terminal 1473e5 (refer to FIG. 56) of the positioning pin 1473e3 (connector 1473e) in the mounting operation of the toner container, the ID. The four metal pads 35a of the chip 1535 are started to contact the four main body side terminals 1473e2 of the connector 1473e. In other words, in the operation of removing the toner container, after the contact of the four metal pads 35a of the ID chip 1535 with the four main body side terminals 1473e2 of the connector 1473e is released, the ground terminal 1535d of the ID chip 1535 is moved to the positioning pin 1473e3 ( The contact is released (separated) from the main body side terminal 1473e5 for grounding of the connector 1473e). Specifically, the connector 1473e is formed so that the contact start position of the grounding main body side terminal 1473e5 is closer to the ID chip 1535 side than the four main body side terminals 1473e2.
With such a configuration, the connection between the metal pad 35a and the main body side terminal 1473e2 is started in a state in which the ID chip 1535 is always grounded in the toner container mounting operation, and the ID is always in the toner container detaching operation. The separation (contact release) between the metal pad 35a and the main body side terminal 1473e2 is started in a state where the chip 1535 is grounded. Therefore, the electric circuit on the ID chip 1535 side is prevented from being electrically floated without being grounded, and the ID chip 1535 is less likely to be electrically damaged.

Also in the eleventh embodiment, the contact-type ID chips 1435 and 1535 (information storage device) move in the moving direction when the metal pad 35a (terminal) approaches and comes into contact with the main body side terminal 1473e2. It is hold | maintained at the holding member 34k (holding | holding part) so that it can move on the virtual plane substantially orthogonal.
Thus, even when the contact type ID chips 1435 and 1535 (information storage devices) are installed in a toner container (detachable device) that is detachably installed on the image forming apparatus main body, the image forming apparatus Contact failure due to poor positioning of the main body connector 1473e with the main body side terminal 1473e2 is less likely to occur.

  As described above, in the eleventh embodiment, contact type ID chips 1435 and 1535 (information storage devices) are attached to a toner container (detachable device) that is detachably installed on the image forming apparatus main body 100. Even when the ID chip 1435 or 1535 is installed, the notch 1435b1 or the hole 1535b11 formed in the substrate 1435b or 1535b of the ID chip 1435 or 1535, and the positioning pin 1473e3 (projection) of the connector 1473e (image forming apparatus main body 100). Since the ground terminals 1435d and 1535d that are engaged with the formed grounding body side terminal 1473e5 are formed, the ID chips 1435 and 1535 are less likely to be electrically damaged.

Embodiment 12 FIG.
59 to 62, a twelfth embodiment of the present invention will be described in detail.
FIG. 59 is a perspective view showing a toner container 1632Y as a detachable device according to the twelfth embodiment.
