Embodiment 1:
As shown in
The intermediate transfer unit 15 is disposed under the toner container accommodating part 70. The imaging parts 6Y, 6M, 6C and 6K corresponding to respective colors (yellow, magenta, cyan, black) are installed side by side so that intermediate transfer belt 8 of the intermediate transfer unit 15 may be faced.
Under the toner containers 32Y, 32M, 32C, and 32K, the toner replenishing devices 60Y, 60M, 60C, and 60K are disposed, respectively. The toner contained in toner containers 32Y, 32M, 32C, and 32K is supplied in the developing devices of the imaging parts 6Y, 6M, 6C, and 6K by the toner replenishing devices 60Y, 60M, 60C, and 60K, respectively.
As shown in
On the photoconductor drum 1Y, an imaging process (a charging process, an exposure process, a developing process, a transfer process, a cleaning process) will be performed, and a yellow image is formed on the photoconductor drum 1Y.
Except that the color of the toner used in other three imaging parts 6M, 6C, and 6K differs, each image part has the same composition as the imaging part 6Y corresponding to yellow, and the image corresponding to each toner color is formed.
Next, a description of other three imaging parts 6M, 6C, and 6K will be omitted, and only the imaging part 6Y corresponding to yellow will be described.
As shown in
Then, the surface of photoconductor drum 1Y arrives at the irradiation position of laser beam L emitted from aligner 7 (see
Then, the surface of photoconductor drum 1Y arrives at an opposed position with the developing device 5Y, an electrostatic latent image is developed in this position, and the toner image of yellow is formed (developing process).
Then, the surface of the photoconductor drum 1Y arrives at the opposed position with the intermediate transfer belt 8 and the first transfer bias roller 9Y, and the toner image on the photoconductor drum 1Y is transferred to the intermediate transfer belt 8 in this position (primary transfer process).
At this time, non-transferred toner remains slightly on the photoconductor drum 1Y.
Then, the surface of photoconductor drum 1Y arrives at the opposed position with the cleaning part 2Y, and the non-transferred toner remaining on the photoconductor drum 1Y in this position is mechanically recovered by the cleaning blade 2a (cleaning process).
Finally, the surface of photoconductor drum 1Y arrives at the opposed position with the non-illustrated electric discharge part, and the rest potential on the photoconductor drum 1Y is removed in this position.
In this way, a series of imaging processes performed on the photoconductor drum 1Y are completed. The imaging process mentioned above is performed on the other imaging parts 6M, 6C, and 6K similar to the yellow imaging part 6Y. That is, the laser beam L based on image information is irradiated from the exposure part 7 disposed under the imaging part to the photoconductor drum of each of the imaging parts 6M, 6C, and 6K. The exposure part 7 emits the laser beam L from a light source, and the laser beam is focused on the photoconductor drum via two or more optical elements, and scanning is performed by the polygon mirror which rotates the laser beam L.
Then, the toner image of each color formed on each photoconductor drum through the developing process is formed on the intermediate transfer belt 8. In this way, a color image is formed on the intermediate transfer belt 8.
As shown in
The intermediate transfer belt 8 is laid firmly and supported by the roller components, and endless movement of the belt is performed by rotation of one roller component 12 in the arrow direction in
Transfer bias contrary to the polarity of the toner is impressed to the primary transfer bias rollers 9Y, 9M, 9C, and 9K. The intermediate transfer belt 8 is rotated in the arrow direction, and passes the primary transfer nip of each of the primary transfer bias rollers 9Y, 9M, 9C, and 9K one by one. In this way, the primary toner image of each color on the photoconductor drums 1Y, 1M, and 1C and 1K is formed on the intermediate transfer belt 8.
The intermediate transfer belt 8 with which the toner image of each color is transferred in piles arrives at an opposed position with secondary transfer roller 19. In this position, the secondary transfer backup roller 12 puts the intermediate transfer belt 8 between the secondary transfer rollers 19, and forms a secondary transfer nip in it.
The toner image of four color formed on intermediate transfer belt 8 is transferred to the recording media P, such as a decalcomania paper delivered in the position of this secondary transfer nip.
At this time, the non-transferred toner which is not transferred by recording medium P remains in intermediate transfer belt 8.
Then, the intermediate transfer belt 8 arrives at the position of a medium transfer cleaning part (it did not illustrate). The non-transferred toner on the intermediate transfer belt 8 is collected in this position. In this way, a series of transfer processes performed on the intermediate transfer belt 8 are completed.
A recording medium P delivered in the position of the secondary transfer nip is delivered via the feed roller 27 or the resist roller pair 28 from the feeding part 26 disposed under the device body part 100. A plurality of recording media P are stored in piles in the feeding part 26. When the feed roller 27 is rotated counterclockwise in
In accordance with the timing with the color image on the intermediate transfer belt 8, the resist roller pair 28 is rotated and the recording medium P is delivered to a secondary transfer nip. In this way, a desired color image is transferred to the recording medium P.
Then, the recording medium P to which the color image is transferred in the position of the secondary transfer nip is delivered in the position of the fixing part 20. The heat and pressure by the fixing roller and the pressurizing roller are fixed to the color image transferred to the surface on recording medium P in this position.
Then, the recording medium P is delivered to the space between the rollers of the delivery roller pair 29 and discharged out of the image forming device. The recording medium P discharged by the delivery roller pair 29 is stacked on the stack part 30 as an output image. In this way, a series of image formation processes in the image forming device are completed.

The toner supplied in the developer accommodating part 54Y circulates through the two developer accommodating parts 53Y and 54Y by the two conveying screws 55Y, being mixed and agitated with the developer G (which is the vertical movement in
The developer G on the developing roller 51Y is delivered to the opposed position (a developing area) with the photoconductor drum 1Y after a proper quantity of the amount of developer turn in this position. The latent image formed on the photoconductor drum 1Y of the electric surface formed in the developing area is adsorbed in toner.
Then, the developer G remaining on the developing roller 51Y reaches above the developer accommodating part 53Y with rotation of the sleeve, and is removed from the developing roller 51Y in this position.

A piezoelectric sensor or the like may be used as the toner end sensor 66Y.
When it is detected by the control unit 90 that the toner stored in the toner tank part 61Y is below a predetermined amount by the toner end sensor 66Y (toner end detection), the control unit 90 performs rotation of the container main part 33Y of the toner container 32Y by the actuator 91 (drive gear 81) by a predetermined time, and performs toner replenishment to the toner tank part 61Y.
When the toner end detection by the toner end sensor 66Y is not canceled after such control is repeatedly performed, a message reporting that no toner is in the toner container 32Y and urging the user to perform exchange of the toner container 32Y is displayed on the display (not illustrated) of the device body part 100.
Although the illustration is omitted, the toner conveyance coil 62Y is installed in the toner conveyance pipe 64Y, and the toner stored in the toner tank part 61Y is delivered to the developing device 5Y via the toner conveyance pipe 64Y. The toner conveyance coil 62Y delivers the toner along with the toner conveyance pipe 64Y to the upper part of the developing device 5Y from the bottom (the lowest point) of the toner tank part 61Y. The toner delivered with toner conveyance coil 62Y is supplied to the developing device 5Y (the developer accommodating part 54Y).

On the other hand, at the time of the detaching operation from the device body part 100, operation that each toner containers 32Y, 32M, 32C, and 32K are contrary to the time of the attaching will be performed.
In the embodiment 1, the antenna 73e (the RFID antenna) is detachably installed in the cap receiving part 73 of the toner container accommodating part 70 installed side by side of each of the toner containers 32Y 32M, 32C, and 32K (refer to
The antenna 73e is provided for performing non-contact wireless communications which is installed in the end face of the cap part 34Y of the toner container 32Y and the RFID chip 35 (see

Before such electronic data is installed in image forming device body 100 by chip 35 (electronic data storage medium) for RFID, it is beforehand stored in it (or after being installed, the information received from the device body part 100 is stored).
Next, the toner containers 32Y, 32M, 32C, and 32K will be described with reference to
The gear 33c which is rotated integrally with the container main part 33Y or with the opening, and the opening A are provided in the head of the container main part 33Y at the end in the longitudinal direction (which is the vertical direction in
The gear 33c is engaged with the drive gear 81 provided in the toner container accommodating part 70 of the device body part 100, in order to rotate the container main part 33Y around its the rotating shaft. Specifically, the gear 33c is formed around the circumference of the opening A, and the plurality of teeth of the gear 33c are formed in radial directions from the rotating shaft of the container main part 33Y.
The gear 33c is partially exposed from the notch 34x (see
As shown in
A spiral projection 33b is formed in the inner circumference surface of the container main part 33Y (which may be a spiral groove if viewed from the outer circumference surface). This spiral projection 33b is for rotating the container main part 33Y to a determined direction, and discharging toner from opening A.
The container main part 33Y constituted in this way can be manufactured by blow molding with the gear 33c and the grip part 33d which are disposed on the circumference. As shown in
The stirring parts 33f are one pair of tabular members installed to the inside of the container main part 33Y from the hollow part B in the cap part 34Y (see
The toner ejection characteristic from the opening A improves because the stirring part 33f is rotated with the opening A of the container main part 33Y.
As shown in
The inside diameter of the head (which is near the position in which the gear 33c is formed) of the container main part 33Y is formed to be smaller than the inside diameter of the accommodating part (which is the position in which spiral projection 33b is formed) in which toner is contained (see
The pumping part (the portion indicated by the dotted line in
Then, the toner pumped up by the small-diameter portion of the head is discharged to the hollow part B of the cap part 34Y from opening A, being agitated by the stirring part 33f.

As shown in
The first hole 34a serves as a positioning main standard of the cap part 34Y in image forming device body 100. The attaching operation of the longitudinal direction of the toner container 32Y to the toner container accommodating part 70 is interlocked with, and the first hole 34a of the cap part 34Y engages with the main reference pin 73a (see
The second hole 34b (sub-reference hole) installed in the longitudinal direction from the end face of the cap part 34Y which intersects vertically in the longitudinal direction is formed in the lower part (bottom) of the cap part 34Y so that the position of the toner outlet W may not be arrived at.
The second hole 34b serves as positioning sub-reference of the cap part 34Y in image forming device body 100. The attaching operation of the longitudinal direction of the toner container 32Y to the toner container accommodating part 70 is interlocked with, and the second hole 34b of the cap part 34Y engages with sub-reference pin 73b (see
The second hole 34b is a long hole which makes the vertical direction the longitudinal direction (this the “direction of a stretcher” differs from the meaning of the “direction of a stretcher” of the toner container 32Y indicated in other parts), as shown in
Positioning of the cap part 34Y in the toner container accommodating part 70 is performed by two holes 34a and 34b constituted in this way.
As shown in
As shown in
This sets in the attaching operation of the longitudinal direction of the toner container 32Y to the toner container accommodating part 70 (the cap receiving part 73). After the engagement of the main reference pin 73a to the first hole 34a used as a positioning main standard is started, the engagement of sub-reference pin 73b to the second hole 34b used as positioning sub-reference will be started, and smooth the attaching of the toner container 32Y to the toner container accommodating part 70 (the cap receiving part 73) is allowed.
While the opening of the first hole 34a and the opening of the second hole 34b are formed in the embodiment 1 on the same virtual plane (which is a virtual plane which intersects vertically with a mounting direction), although the root part of the main reference pin 73a and the root part of sub-reference pin 73b are formed on the same virtual plane (it is a virtual plane which intersects vertically with a mounting direction). In a case where these openings or root parts are not formed on the same virtual plane, the distance difference of the mounting direction of the position of the point of the main reference pin 73a, and the position of the point of sub-reference pin 73b are formed to be longer than the distance difference of the mounting direction of the position of the opening of the first hole 34a, and the position of the opening of the second hole 34b.
After the engagement of the main reference pin 73a to the first hole 34a used as a positioning main standard is started like the embodiment 1, the engagement of sub-reference pin 73b to the second hole 34b used as positioning sub-reference will be started.
The first hole 34a long in the longitudinal direction in this way is formed in the ceiling part (portion which is not buried in toner) of the cap part 34Y. The influence which it has on the conveyance characteristic (mobility) of the toner in cap part 34Y will not arise. The second hole 34b short in the longitudinal direction is formed in the bottom of the cap part 34Y.
However, it can install using the short space from the end face of the cap part 34Y to the position of the toner outlet W, and the function as positioning sub-reference is fully exhibited.
As shown in
The first engagement part 34e and 34f of the second engagement part all, while projecting in the vertical direction upper part from the outer circumference surface of the cap part 34Y so that it may become a line symmetry form to the virtual altitude passing through the hole center of the first hole 34a when it sees in the part (which is a part which is parallel to the front view of
The first engagement part 34e and 34f of the second engagement part engage with the engagement part 73m of the cap receiving part 73 shown in
On the other hand, the second engagement part 34f is formed in the both sides of the first engagement part 34e so that the first engagement part 34e may be pinched. It engages with the engagement part 73m formed in the cap receiving part 73 so that the first engagement part 34e and 34f of the second engagement part may enter.
Since the tapered shape lobe 34e1 in the first hole 34a engages with the engagement part 73m ahead of the second engagement part 34f when the cap part 34Y is attached to the cap receiving part 73, and the attaching operation of the cap part 34Y to the cap receiving part 73 can be performed smoothly.
As shown in
When the shoulder 34q equips the toner container accommodating part 70 with toner container 32Y, it is interlocked with the attaching operation and contacts positioning part 73q (see
Therefore, the deflection of the cap part 34Y in the cap receiving part 73 will be controlled, and the attaching of the cap part 34Y to the cap receiving part 73 will be performed smoothly.
As shown in
The cap part 34Y is attached to the cap receiving part 73 of the toner container accommodating part 70 (the image forming device body 100) with the pressing part 34c. Or when breaking away, it is pressed in the direction which resists the force of the mounting direction (or the detaching operation direction) by the pressing part 73d of the cap receiving part 73 (see
Therefore, the user can perform the attaching operation of the toner container 32Y to the cap receiving part 73. Or in the detaching operation, after feeling the reaction force which resists the control force of a mounting direction (or the detaching operation direction) in the position where pressing part 34c and the pressing part 73d are engaged, the control force of a mounting direction (or the detaching operation direction) will be heightened, and the attaching operation (or detaching operation) will be completed at a stretch.
Therefore, the user can get a high click feeling in the attaching operation (or detaching operation) of the toner container 32Y to the cap receiving part 73.
As shown in
The pressing part 34c projects on the horizontal sides from the outer circumference surface of the cap part 34Y so that it may be disposed on the virtual horizontal line passing through the middle point for the imaginary line which connects the hole center of the first hole 34a, and the hole center of the second hole 34b when it sees in the part which intersects vertically in the longitudinal direction, it is installed in the longitudinal direction (it is a space vertical direction of

As shown in
In the embodiment 1, the RFID chip 35 is fixed to the position between the first hole 34a (the main reference hole) and the second hole 34b (sub-reference hole). The position of the RFID chip 35 to the antenna 73e of the cap receiving part 73 is defined with high precision. Therefore, it is possible to prevent poor communications from occurring due to the deviation of the RFID chip 35 to the antenna 73e.

By this composition, it is possible to prevent the problem that the toner container of a different color (for example, the toner container for the yellow) is set to the toner container accommodating part of a predetermined color (for example, the toner container accommodating part for the cyan) resulting in the non-formation of a desired color image. That is, the wrong setting of the toner container to the toner container accommodating part is prevented.
Alternatively, the shapes of the non-compatible shape parts 34g for different toner containers as shown in
The cap part 34Y in the embodiment 1 is formed so that the non-compatible shape part 34g has a convex or concave shape, extends along the longitudinal direction of the container main part 33Y side, and is arranged to confront from the position of the head end of the cap part 34Y in the longitudinal direction toward the container main part 33Y.

It is necessary to judge the incompatibility of the toner container in the position of the cap receiving part 73 in the toner container accommodating part 70. Therefore, the composition of providing the non-compatible shape part 34g at the head of the cap part 34Y as mentioned above becomes useful. These parts are two projections formed in the head upper part of the cap part 34Y radially the non-compatible shape part 34g with reference to
Next, the non-compatible shape parts 34g of various shapes which can be formed will be described with reference to
It is not necessary to manufacture the kind of the toner container (cap part), and the metallic mold of the same number. By this composition, the cap part which has two or more kinds of incompatibility with one metallic mold can be formed, and the manufacturing cost of the kinds of the whole the toner container can be reduced.
As shown in
Since the kind of the toner container is specified, the non-compatible shape part 34g formed in the point of the cap part 34Y make a different position on the outer circumference surface of the cap part 34Y extend in the shape of a convex along the longitudinal direction for every kind.
Although the non-compatible shape part 34g of the cap part 34Y are formed in the shape of a convex and fitting part 73c of the cap receiving part 73 is formed in the concave part in the embodiment 1, the non-compatible shape part 34g of the cap part 34Y can be formed in a concave part, and fitting part 73c of the cap receiving part 73 can also be formed in the shape of a convex.

The portion (the accommodating part 34z) in which the container main part 33Y is inserted, and the shutter accommodating part 34n are not divided with the wall, but form a series of space. Therefore, in the state in which the container main part 33Y is inserted in the cap part 34Y, a part will be vacant as for the space of the rectangle in the lower part of the accommodating part 34z.
The shutter accommodating parts 34n hold the shutter deforming parts 34d2 after the shutter member 34d opens the toner outlet W. As shown in
The slide groove 34n1 and the shutter rail 34t are formed in parallel with the longitudinal direction by each. The shutter rail 34t does not extend to the shutter accommodating part 34n, but a gap exists between the shutter rail 34t and the shutter accommodating part 34n.
The composition and operation of the shutter member 34d will be described.

Specifically, the wall is set up between the perimeter of the claw part formation part 34i and the perimeter of the hollow part B, and the first hole 34j 1 is formed in this wall. This hole is equivalent to the first hole 34j 1 formed in the inner circumference side of the claw part 34j in
The first hole 34j 1 formed in the inner circumference side of the claw part 34j is formed in the adhesion surface 34v on which the cap seal 37 is stuck as shown in
The second hole 34j3 formed in the outer circumference surface side of the claw part 34j as shown in
As shown in
Thus, in the embodiment 1, the cap part 34Y is formed by integral molding. Compared with the case where adhesion or welding of two or more molding parts is performed, the problem of inaccurate dimensions of the cap part due to the variation in the accuracy of adhesion or welding can be prevented.
Therefore, the gap between the container main part 33Y and the cap part 34Y will be maintained with good accuracy. The problem of degradation of the sealing characteristic between the components 33Y and 34Y with the cap seal 37, and the problem of shifting of the position of the toner outlet W of the cap part 34Y from the toner replenishment mouth 72w of the image forming device body 100 causing toner scattering can be prevented. The cap part 34Y is formed by integral molding, and the mechanical intensity of the cap part 34Y can be increased when compared with the case where adhesion or welding of two or more molding parts is performed. The cost of metallic molds can be reduced.

Specifically, a cylindrical fixture (for example, a phillips screwdriver) may be inserted from the notch 34x (the insertion opening) and the head of the fixture may be inserted in the recess 34v1. That is, the head of the fixture is inserted in the part of the underside (the adhesion surface side) of the cap seal 37.
The cap seal 37 is separated for the recess 34x1 from adhesion surface 34v as the fulcrum point, carrying out engagement of the center part of the cylindrical fixture to recess 34x1. The film member 37a is stuck on the surface where the cap seal 37 in the embodiment 1 is stuck on the cap part 37Y. The film member 37a is hard compared with the foamed resin material which is formed of a material, such as a polyester film, and constitutes the main part of the cap seal 37. The separation operation characteristic by the fixture mentioned above will improve.
The recess 34v1 for separating the cap seal 37 is formed in the position corresponding to the inner circumference side of the cap seal 37, and formed in the position corresponding to the outside of the region of the region where the cap seal 37 contacts the container main part 33Y. That is, the recess 34v1 is formed so that the portion which separated from the region which actually contributes to sealing characteristic in cap seal 37 may be faced.
The problem that the sealing characteristic of both components 33Y and 34Y falls by this so that cap seal 37 inserted between the container main part 33Y and cap part 34Y may not change into by the recess 34v1 is prevented.
The cap seal 37 is disposed on the container main part 33Y side in the longitudinal direction (it is a left of
The cap part 34Y is formed so that the outer diameter of the point in which pressing part 34c is formed may become smaller than the outer diameter of the portion in which adhesion surface 34v of the cap seal 37 is formed. Therefore, even if the pressing part 34c is formed, the outer diameter does not become so large, but the point of the cap part 34Y can secure the adhesion surface of the cap seal 37 somewhat greatly.
That is, without enlarging the cap part 34Y, the high sealing characteristic of the container main part 33Y and the cap part 34Y will be maintained, and the attaching/detaching operation of the toner container 32Y will be performed smoothly.
As shown in
As shown in
The two vertical walls 34s formed in the both-sides edge of the cap part 34Y respectively are continuously formed to the position which projects in the longitudinal direction (mounting direction) from the end of the close direction of the shutter member 34d to the position which closes the toner outlet W (see
In the embodiment 1, the portion which functions as the shutter rail 34t is a portion prolonged in the container main part 33Y side from the lock projection mentioned above. The vertical walls 34s are further prolonged toward the front side from the position of the lock projection mentioned above. The heights 34m which project from the end face which intersects vertically in the longitudinal direction (mounting direction) are formed in the cap part 34Y. The heights 34m are disposed near the lower end of the second hole 34b so that the second hole 34b may be pinched in the direction of the shorter side (it is a space vertical direction of
The bottom of the two heights 34m is prolonged to the respectively same height as the rib (the edge of the hole 34b) which forms the second hole 34b.
The head part of the heights 34m in the shape can be connected, one tabular height can be formed, and the both side surfaces of the height can also be used as 34s of vertical wall.
The vertical walls 34s constituted in this way are pinching sides which are pinched by the first sandwiching part 72d1 of the shutter close mechanism 72d (shutter pinching mechanism) in the cap receiving part 73 (the toner container accommodating part 70) (see
As opposed to the timing in which the shutter close mechanism 72d closes the shutter member 34d thoroughly when taking out the toner container 32Y from the toner container accommodating part 70, the shutter close mechanism 72d (the second sandwiching part 72d2) can delay the timing which cancels holding of the shutter member 34d on the vertical walls 34s.
Hence, the problem that the toner container 32Y is taken out from the device body part 100 before the shutter member 34d closes the toner outlet W thoroughly will be prevented. Especially, the point of the longitudinal direction of 34m of two heights (mounting direction) in the last timing in case the cap part 34Y separates from the cap receiving part 73 since it is in the position projected in the longitudinal direction (mounting direction) from the end face of the first hole 34a, release of holding of the shutter member 34d by 72d (72d2 of the second sandwiching part) of shutter close mechanisms is performed, and the effect of preventing poor closing of the shutter member 34d mentioned above will become positive. The composition and operation of 72d (shutter pinching mechanism) of shutter close mechanisms will be described later with reference to
The shutter member 34d to which the shutter seal 36 is stuck on the opposite surface with the toner outlet W is installed in the bottom of the cap part 34Y. The shutter member 34d is for opening and closing the toner outlet B, which is interlocked with the attaching/detaching operation of the toner container 32Y to the toner container accommodating part 70, as shown in
As shown in
The shutter sliders 34d12 of the shutter main part 34d1 are engaged with the slide grooves 34n1 of the cap part 34Y (the first rail part), and engaged so that the shutter rail 34t (the second rail part) of the cap part 34Y is inserted between the shutter seal 36 and the shutter rail engagement parts 34d15 of the shutter main part 34d1. The shutter main part 34d1 opens and closes the toner outlet W because the shutter member 34d moves along with these rail parts 34n1 and 34t.
In the embodiment 1, the longitudinal length (the length of the toner container 32Y in the insertion direction) of the slide groove 34n1 (the first rail part), formed in the shutter accommodating part 34n as shown in
The shutter seal 36 as a seal member is stuck on the upper surface (which faces the toner outlet W) of the shutter main part 34d1. The shutter seal 36 is for preventing leakage of toner from the space between the toner outlet W and the shutter main part 34d1 in the state in which the shutter main part 34d1 (the shutter member 34d) closes the toner outlet W. The shutter seal 36 may be formed of a foamed resin material, etc.
As shown in
The shutter deforming part 34d2 of the shutter main part 34d1 is disposed in the container main part 33Y side in the longitudinal direction (see
The stopper part 34d22 of the shutter deforming part 34d2 is the wall part formed in the end part of the shutter deforming part 34d2 in the opening direction (the left direction in
The stopper release part 34d21 of the shutter deforming part 34d2 is formed to project to the lower part in the vertical direction. By receiving an external force from the lower part, the stopper release part 34d21 moves up the stopper part 34d22 in connection with elastic deformation of the shutter deforming part 34d2, canceling the contact state of the contact part 34n5. The stopper release part 34d21 is the projection with slopes formed on both sides in the longitudinal direction, which is formed between the stopper part 34d22 and the connecting location (which is a connecting location of the shutter main part 34d1 and the shutter deforming parts 34d2).
The stopper release part 34d21 is interlocked with the attaching operation of the toner container 32Y to the toner container accommodating part 70, and contacts the stopper release energizing part 72b (see
In the embodiment 1, the shutter deforming part 34d2 inclines toward the lower part and is pushed up by the stopper release energizing part 72b. By elastic deformation of the shutter deforming part 34d2, the inclination is canceled and it is linear to the shutter main part 34d1. Therefore, the amount in which two bend backward up to the shutter deforming part 34d1 within the shutter accommodating part 34n in the shutter main part 34d decreases (or the amount bending backward becomes zero). Therefore, the problem of two contacting the container main part 33Y in 34d of shutter deforming parts contained in shutter accommodating part 34n will be prevented, and the space which is the shutter accommodating part 34n will be utilized effectively.
Next, operation of the shutter member 34d interlocked with the attaching operation of the toner container 32Y to the toner container accommodating part 70 will be described with reference to
The positions of the shutter member 34d in
When the stopper release part 34d21 of the shutter member 34d has not arrived at the position of stopper release energizing part 72b (
Subsequently, if the attaching operation of the toner container 32Y progresses, as shown in
Subsequently, the shutter member 34d contacts the wall part (see
However, movement of the toner container 32Y in the mounting direction is advanced, relative movement of the shutter member 34d in the opening direction is performed.
As shown in
The toner container 32Y in the embodiment 1 has the shutter deforming part 34d2 which performs elastic deformation of the shutter member 34d on the basis of the connecting location with the shutter main part 34d1. The stopper part 34d22 which regulates movement of the shutter member 34d in the opening direction, and the stopper release part 34d21 which cancels regulation of the movement are provided in the shutter deforming part 34d2. When the toner container 32Y is in the isolated state, the toner outlet W is not freely opened by the shutter member 34d. Only when the toner container 32Y is attached to the image forming device body 100, the opening operation which causes the shutter member 34d to open the toner outlet W is interlocked with the attaching operation of the toner container 32Y.
As shown in
If the rib 34p is formed to extend in the longitudinal direction (the longitudinal direction in
As shown in
The sandwiching parts 34d11 include the engagement wall 34d11 a raised at the head end of the shutter main part 34d1 in the mounting direction, the prevention wall 34d11b formed above the sandwiching parts 34d11 to extend in parallel with the mounting direction, and the side wall 34d11c.
At the time of the opening/closing action of the shutter member 34d, the sandwiching parts 34d11 of the shutter member 34d are pinched by the second sandwiching member 72d2 of shutter close mechanism 72d (shutter pinching mechanism) and the vertical surface 34s of the cap part 34Y is pinched by the first sandwiching member 72d1 of the shutter close mechanism 72d (shutter pinching mechanism). In this way, the posture of the cap part 34Y and the shutter member 34d in the cap receiving part 73 at the time of the opening/closing action of the shutter member 34d will be defined.
In the toner container 32Y in the embodiment 1, the stopper release part 34d21 of the shutter member 34d, as shown in
The problem that the toner with which the opening operation (release operation of stopper part 34d22 by the stopper release part 34d21) of the shutter member 34d with which it is covered is started, and color differs will turn to image forming device body 100, and will be accidentally supplied from the toner outlet W is prevented certainly. The image forming device 100 in the embodiment 1 is constituted so that slide movement may be performed horizontally (the longitudinal direction) and the attaching operation may be completed, after the toner container 34Y is laid from the upper part to the toner container accommodating part 70, as shown in
It is necessary to judge the incompatibility of the toner container in the position of the cap receiving part 73 in the toner container accommodating part 70. Therefore, the composition of providing the non-compatible shape part 34g at the head of the cap part 34Y as mentioned above will be useful. In the slide groove 34n, the toner container 32Y in the embodiment 1 has the shutter main part 34d1 in the shutter member 34d (the first rail part) and the shutter rail 34t (the second rail part) as the rail parts for guiding the operation that opens and closes the toner outlet W.
As shown in
As shown in
Specifically, as shown in
Alternatively, the cap part 34Y in the embodiment 1 may be constituted so that the distance of the portion in which the shutter member 34d are supported the shutter main part 34d1 with operation which opens the toner outlet W in 34n of slide grooves, and the portion supported with shutter rail 34t may become short.
As shown in
Therefore, when 1 is supported in the long span as for 34d1 of shutter main parts (it is in the state of
The shutter main part 34d1 in the sliding direction the degree of the shutter deforming part 34d2 (elastic deformation is performed by the contact to the shutter accommodating part 34n) elastic deformation which are connected to the end (end on the side of the container main part 33Y) as for the shutter main part 34d1 becomes small.
When this is continuously seen to compensate for the opening operation of the shutter member 34d, the shutter deforming part 34d2 of shutter variant-parts/two/amount of elastic deformation
It becomes the maximum when releasing of the stopper part 34d22 is performed by the stopper release part 34d21 (it is a time of 21 being pushed up by stopper release energizing part 72b of the device body part 100 as for the stopper release part 34d21).
In the shutter main part 34d1 also dwindles the amount of elastic deformation with gradual decrease of the span which is supported with 1 and shutter rail 34t in 34n of slide grooves after that.
Even if the state (the state of
Since the shutter deforming part 34d2 amount of elastic deformation gradually decreases in connection with the opening operation of the shutter member 34d, the attaching operation (opening operation of the shutter member 34d) of the toner container 32Y will also be performed smoothly. When the shutter member 34d opens the toner outlet W wide thoroughly in the composition mentioned above (it is in the state of
In that case, since is supported the shutter main part 34d1 in 34n of slide grooves and the shutter member 34d can enlarge the amount of loosening further in the state in which the toner outlet W is opened wide thoroughly, the shutter deforming part 34d2 amount of elastic deformation also becomes still smaller and can make the effect mentioned above more effective.
In the embodiment 1, with reference to
In the embodiment 1, in order for the stopper release part 34d21 to the shutter accommodating part 34n to reduce the contact force of 21, the notch 34n6 (hole), but 34n of notches can also establish a slot in the same range instead of 6 (hole).
Although the notch 34n6 (hole) formed in the position (range) through which 21 passes in connection with the opening operation of the shutter member 34d in 34d of the shutter deforming part 34d2 stopper release parts in the embodiment 1, a hole or a slot can also be formed in the position which 21 stops with termination of the opening operation of the shutter member 34d in the stopper release part 34d21.
In this case, the shutter deforming part 34d2 is in the state of elastic deformation (the state of
The shutter accommodating part 34n in the embodiment 1 is for performing smoothly the opening/closing action of the shutter member 34d. Namely, that for which the shutter accommodating part 34n are provided in cap part 34Y, the state in which the shutter member 34d have opened the toner outlet W wide as well as the state in which the toner outlet W is closed by the shutter member 34d, in order to unite with the cap part 34Y, without the shutter member 34d projecting in the lower part from the cap part 34Y, the opening/closing action of the shutter member 34d is performed smoothly.
In the cap part 34Y in the embodiment 1, the five claw parts 34j are disposed inside in the peripheral direction side by side in order to hold the container main part 33Y rotatably, as shown in
As mentioned above, the shutter accommodating part 34n is the portion in which the shutter deforming part 34d2 is formed and the claw part 34j is not formed, and the space to the container main part 33Y becomes large. Therefore, at the bottom (where the shutter accommodating part 34n is provided) of the cap part 34Y, the force (restraining force) of holding the container main part 33Y becomes small.
On the other hand, in the embodiment 1, the claw part 34j is disposed in the upper part which faces the shutter accommodating part 34n. Even if the restraining force of the cap part 34Y to the lower part of the container main part 33Y tends to be weak and the container main part 33Y tends to fall on in the sliding direction, the claw part 34j disposed in the upper part which faces the shutter accommodating part 34n to be canceled will hold the container main part 33Y. Therefore, the container main part 33Y will be held with good balance by the cap part 34Y covering the peripheral direction. As shown in
As mentioned above, even if the restraining force of the cap part 34Y to the lower part of the container main part 33Y tends to be weak and the container main part 33Y tends to fall on in the sliding direction, the operation will be restricted because the lobe H of the cap part 34Y contacts the container main part 33Y. Therefore, the container main part 33Y will be held with good balance by the cap part 34Y.
As shown in
The edge 34r which projects to the lower part around the toner outlet W is formed in cap part 34Y. This edge 34r is formed in the longitudinal direction in the pointed shaped toward the direction where the point 34r1 of the both sides of the longitudinal direction (the longitudinal direction in
The point 34r1 of the longitudinal direction (which is also a direction in which the shutter member 34d are opened and closed) of the edge 34r around the toner outlet W is formed in the pointed shaped, and the shutter seal 36 stuck on the shutter member 34d and the slide contact at the edge 34r1 is started by the pointed-shape point 34r1 in a small area and the sliding contact surface product spreads gradually when closing the shutter member 34d. Thus, it is difficult to produce peeling and breakage on shutter seal 36 by contact with edge 34r. Since the sliding contact surface product with edge 34r narrows gradually also when opening the shutter member 34d, the damage to shutter seal 36 by contact with edge 34r decreases.
As shown in
Since the sliding contact surface product of seal member 76 of the toner replenishment mouth 72w and edge 34r narrows gradually also when performing detaching operation of the longitudinal direction of the toner container 32Y, the damage to seal member 76 of the toner replenishment mouth 72w by contact with edge 34r decreases.
Therefore, the problem that the toner stored in the toner container 32Y disperses outside with the attaching/detaching operation of the toner container 32Y to the device body part 100 is prevented.
As shown in
If the shutter seal 36 stuck on the shutter member 34d with the attaching/detaching operation of the longitudinal direction of the toner container 32Y is worn with the edge 34r, it is possible to prevent the damage on the shutter seal 36. If the seal member 76 (see
In the embodiment 1, the toner which satisfies the following requirements is used in the toner containers 32Y, 32M, 32C and 32K. Assuming that Dn (micrometer) denotes the number average particle diameter and Dv (micrometer) denotes the volume average particle diameter, the requirements for the toner are represented by the following.
3<=Dv<=8 (1)
1.00<=Dv/Dn<=1.40 (2)
By using the toner satisfying the requirements of the above formulas, selection of the toner particles according to an image pattern is performed at the time of a developing process and good image quality is maintained, even if the toner is agitated in the developing device for a long time, good development characteristic is maintained. The toner will be delivered efficiently and certainly, without blocking the toner replenishment passage of the tube 71.
Typically, measurement of the volume average particle diameter and the number average particle diameter of the toner can be performed using the “Coulter counter TA-2” (made by Coulter company) or the “Coulter multisizer 2” (made by Coulter company).
In the embodiment 1, the spherical shape particle toner which is formed so that the shape factor SF-1 is in a range of 100-180 and the shape factor SF-2 is in a range of 100-180 is used as the toner contained in the toner containers 32Y, 32M, 32C and 32K. Lowering of cleaning performance can be prevented this maintaining high transfer efficiency. The toner will be delivered efficiently and certainly, without blocking the toner replenishment passage of the tube 71.
The shape factor SF-1 represents the spheroidicity of the toner particles, and can be determined in accordance with the following formula.
SF-1=(M2/S)×(100πi/4)
In the above formula, M is a maximum grain size in the plane of projection of the toner particles, and S is the area of the plane of projection of the toner particles. Therefore, the toner particles whose shape factor SF-1 is 100 are true spheres, and the spheroidicity is reduced as the shape factor is increased from 100.
The shape factor SF-2 represents the degree of unevenness of the toner particles, and it can be determined in accordance with the following formula.
SF-2=(N2/S)×(100/4π)
In the above formula, N is a circumference in the plane of projection of the toner particles, and S is the area of the plane of projection of the toner particles. Therefore, the toner particles whose shape factor SF-2 is equal to 100 do not have unevenness, and the unevenness is increased as the shape factor is increased from 100.
The shape factor SF-1 and the shape factor SF-2 are determined by the analysis and search of the photographic image of the toner particles captured with the scanning electron microscope “S-800” (made by Hitachi, Ltd.) with the image analyzing device “LUSEX3” (made by Nireco Corp).
Next, the toner container accommodating part 70 (the container receiving part 72, the cap receiving part 73) will be described with reference to
As shown in
As shown in
In
As shown in
The bottle abutment 72a functions as a sliding surface of the toner container 32Y at the time of the attaching/detaching operation of the toner container 32Y, and after the set of the toner container 32Y is completed, it functions as the maintenance part of the container main part 33Y to rotate.
The stopper release energizing part 72b is a rib of the trapezoidal shape formed in the cap receiving part 73 side (it is a mounting direction lower stream side of the toner container 32Y) in the bottle abutment 72a.
The stopper release energizing part 72b is for being interlocked with the attaching operation of the toner container 32Y, the stopper release part 34d21 of shutter member 34Y pushing up 21, and 34d of stopper part 22 and 34n of contact parts canceling the contact state of 5 (it is for making possible opening operation of the shutter member 34d).
As shown in
The shutter close mechanism 72d are one pair of components of the horseshoe shape disposed so that the sliding direction of
The first sandwiching part 72d 1 is formed in the one end side, and 72d (shutter pinching mechanism) of shutter close mechanisms are formed in the other end side in 72d2 of the second sandwiching part.
At the time of the opening/closing action of the shutter member 34d in the toner container 32Y as explained previously, the two second pinching components 72d11 are pinched to the sandwiching parts 34d1 of the shutter member 34d, and the vertical surfaces 34s of the cap part 34Y are pinched to the first pinching components 72d1. The shutter member 34d in the cap receiving part 73 at the time of the opening/closing action of the shutter member 34d and the posture of the cap part 34Y are defined, and a smooth opening/closing action becomes possible.
Operation of the shutter close mechanism 72d (shutter pinching mechanism) accompanying the opening/closing action of the shutter member 34d will be described later with reference to
As shown in
As explained using
Here, with reference to
The main reference pin 73a and sub-reference pin 73b are installed in the longitudinal direction (it is a path of insertion of the toner container 32Y) by each. The point tapers off and the main reference pin 73a has form.
When performing the attaching operation of the toner container 32Y to the cap receiving part 73 in the longitudinal direction, a smooth attaching operation of the toner container 32Y to the cap receiving part 73 is allowed. The engagement parts 73m are engaged with the first engagement part 34e and 34f (specification part) of the second engagement part which are formed in cap part 34Y of the toner container 32Y.
While the posture of the cap part 34Y is regulated and cap part 34Y is detached and attached to the cap receiving part 73 by this, the posture of the cap part 34Y in the state in which the cap receiving part 73 is equipped with cap part 34Y is regulated. The fitting part 73c is engaged with the non-compatible shape part 34g formed in the point of the cap part 34Y of the toner container 32Y. Thus, that for which the fitting part 73c corresponding to the non-compatible shape part 34g of the toner container 32Y is formed in the cap receiving part 73
The nonconformity by which wrong setting of the toner container (for example, it is the toner container of yellow) of different color is performed to the toner container accommodating part (for example, it is the toner container accommodating part of cyan) of predetermined color is prevented.
Here, the fitting part 73c is formed in the side near the container receiving part 72 of the longitudinal direction in the cap receiving part 73 with reference to
The image forming device 100 in the embodiment 1 is constituted so that slide movement may be performed horizontally (the longitudinal direction) and the attaching operation may be completed, after the toner container 34Y is laid from the upper part to the toner container accommodating part 70, as shown in
In the attaching operation of the toner container 32Y so that stopper release energizing part 72b may engage with 21 in the stopper release part 34d21 of the cap part 34Y after the non-compatible shape part 34g of the cap part 34Y fit into fitting part 73c, the positional relationship of stopper release energizing part 72b and fitting part 73c is set up.
Since the opening operation of 45d of shutter members will be performed by this after a judgment of incompatibility is made, the effect which deters the problem to which the toner which prevents the wrong setting of the toner container mentioned above, and with which color differs is supplied will become still more positive.
It is for bearing 73k supporting the driving shaft of drive gear 81 in actuator 91 free rotation to the cap receiving part 73 with reference to
The antenna 73e is installed in the end face on the side of the back in the cap receiving part 73.
This antenna 73e is for performing non-contact wireless communications which are installed in the end face of the cap part 34Y of the toner container 32Y, and the RFID chip 35 (see
As shown in
With reference to
Slide block 73d1 includes a recess (hollow part) 73d13 which holds or receives the end of torsion spring 73d2. The slide block 73d1 is inserted in the insertion opening 73d6 of the cap receiving part 73 as shown in
The torsion spring 73d2 is an elastic body which urges the slide block 73d1 towards the pressing part. Alternative elastic bodies may be used such as other types of springs or elastic elements such as a coil spring, a leaf spring, or a compression spring. Further, the elastic body can be made out of metal, plastic, or resin, or any other suitable material.
By this composition, energization or urging of each slide block 73d will be in the arrow direction (which faces the toner container 32Y) of
As shown in
As shown in
Once the pressing part 34c crosses the peak of the slide block 73d1 as shown in
In this way, the cap part 34Y arrives at the position (regular fixing point) where the toner outlet W corresponds to toner replenishment mouth 72w.
When the slide block 73d1 contacts the peak of the slope of pressing part 34c, the slide block 73d1 presses pressing part 34c in the direction which intersects vertically in the longitudinal direction.
Thus, when the pressing part 34c contacts the slope 73d11, the torsion spring 73d2 resists the insertion of the toner container 32Y. Once the pressing part 34c transitions to the slope 73d12, the torsion spring assists or helps pull the toner container 32Y to the mounted position and assists in holding the toner container at the mounted position.
During the attaching operation of the toner container 32Y, the user inserts the toner container 32Y in the cap receiving part 73, feeling a small resistance immediately after the operation starts. A stronger resistance is felt when the slide block 34d1 is pressed by pressing part 34c. Subsequently, when the slide block 34d1 crosses the peak of the pressing part 34c, there is a feeling of less resistance and a feeling that the toner container 32Y is pulled to its final position and firmly fitted in at the back side. Thus, in the attaching operation of the toner container 32Y, cap part 34Y of the toner container 32Y, improper installation can be avoided as compared to conventional systems which do not provide a clear click feeling.
As shown in
When one pair of pressing parts 73d contacts a corresponding pair of pressing parts 34c as shown in
The pressing parts 34c are illustrated as having two surfaces which contact the slide blocks 73d1. However, according to an alternative embodiment, different shapes of the pressing parts 34c may be utilized. For example, the pressing part 34c may have one contacted surface which is flat, pointed, or rounded. Further, the pressing part 34c may have three or more contact surfaces.
Additionally, the pressing parts 34c are protrusions which are mounted on the cap, and the cap is part of the toner container. Thus, the pressing parts are also considered to be mounted on the toner container. In embodiment 1, the attaching operation of the toner container 32Y proceeds as shown in
While the opening of the main reference hole 34a is formed in the head part rather than the peak of pressing part 34c in cap part 34Y, specifically, the main reference pin 73a is installed in the container receiving part 72 side rather than the position in which slide block 34d1 is installed in the cap receiving part 73.
Since the pressing of the pressing part 34c by the pressing parts 73d is started after the position of the cap part 34Y in the cap receiving part 73 is settled or started, when one pair of pressing parts 34c are pressed by the corresponding pair of pressing parts 73d at the time of attachment and detachment of the toner container 32Y, the cap part 34Y will be uniformly pressed in the sliding direction of
As shown in
Subsequently, as shown in
The movement of the shutter member 34d in the cap receiving part 73 is regulated (the shutter member 34d will not move in the longitudinal direction absolutely). However, the movement of the mounting direction of the toner container 32Y is advanced, and relative movement of the opening direction of the shutter member 34d is performed.
That is, as shown in
On the other hand, operation is performed by the procedure contrary to the procedure at the time of the attaching operation when carrying out extraction (the detaching operation) of the toner container 32Y from the toner container accommodating part 70 (the cap receiving part 73). That is, operation of 72d (shutter pinching mechanism) of shutter close mechanisms accompanying closing operation of the shutter member 34d is performed in the order of
As opposed to the timing to which the shutter close mechanism 72d close the shutter member 34d thoroughly when taking out toner container 32Y from the toner container accommodating part 70, 72d (72d2 of the second sandwiching part) of shutter close mechanisms can delay the timing which cancels maintenance of 34d (34d of sandwiching parts 11) of shutter members on the basis of 34s of vertical wall.
That is, when closing operation of the shutter member 34d is performed (it is relative movement of the shutter member 34d from a state to the state of
In the embodiment 1, the cap part 34Y has the height 34m, and the problem that the toner container 32Y is taken out from the device body part 100 before the shutter member 34d close the toner outlet W thoroughly is prevented.
As shown in
As shown in
Accordingly, the attaching/detaching operation of the toner container 34Y can be performed smoothly, and the sealing characteristic of the container main part 33Y and the cap part 34Y can be maintained at high level, without enlarging the cap part 34Y.
Embodiment 2:
The toner container in the embodiment 2 differs from that of the embodiment 1 (in which the cap part is formed by integral molding) in that the cap part is formed by welding of two molding members.
The toner container 32Y in the embodiment 2 is constituted similar to that of the embodiment 1 to include the container main part 33Y (bottle body) and the cap part 34Y provided in the head of the container main part. The toner container 32Y further includes the stirring member 33f, the cap seal 37, the shutter member 34d, the shutter seal 36, and the RFID 35, in addition to the container main part 33Y, and the cap part 34Y.
Unlike that of the embodiment 1, the cap part 34Y (from which the cap seal 37, the shutter member 34d, the shutter seal 36, and the RFID 35 are taken out) in the second embodiment 2 is formed by welding (or adhesion) of the two molding members 34Y1 and 34Y2.
The cap part 34Y includes the first member 34Y1 and the second member 34Y2. The toner outlet W, the pressing part 34c, and the adhesion surface 34v to stick the cap seal 37 are formed in the first member 34Y1. In the second member 34Y2, a small-diameter portion 34Y2d which covers a part of the first member 34Y1, and a large-diameter portion (which is the portion in which the accommodating part 34z is formed) which has an outer diameter larger than that of the small-diameter portion 34Y2d, are formed. The upper part (the portion in which the main reference hole 34a is formed) of the first member 34Y1, the side part 34Y1b (the portion in which the pressing part 34c is formed) of the first member 34Y1, and the bottom (the portion in which the toner outlet W is formed) of the first member 34Y1 are respectively inserted in the notches 34Y2a, 34Y2b, and 34Y2c of the second member 34Y2, and the small-diameter portion 34Y2d of the second member 34Y2 is bonded to the junction 34Y1a of the first member 34Y1 (welding).
As shown in
The cap part 34Y in the embodiment 2 includes the two molding members 34Y1 and 34Y2. When compared with that of the embodiment 1 (in which the cap part is formed by one molding member), the arrangement of the respective parts, such as the claw part 34j, the non-compatible shape part 34g, the pressing part 34c, the toner outlet W, and the toner drop passage C, becomes more flexible.
In the toner container in the embodiment 2, the positional relationship in the longitudinal direction between the cap seal 37 (which is installed between the container main part 33Y and the cap part 34Y) and the pressing part 34c which projects on the outer circumference surface of the cap part 34Y and is pressed in the direction which resists the force of the mounting direction when the cap part 34Y is attached to the image forming device body 100, is optimized. Thereby, the attaching/detaching operation of the toner container 34Y can be performed smoothly, maintaining the high sealing characteristic of the container main part 33Y and the cap part 34Y, without enlarging the cap part 34Y.
Embodiment 3:
The toner container 32Y in the embodiment 3 as well as that of the embodiment 1 comes out mainly with main part 33Y (bottle body) of a container, and cap part 34Y (bottle cap) provided in the head, and is constituted. The toner container 32Y in the embodiment 3 besides the container main part 33Y and the cap part 34Y, is decomposed into the RFID chip 35 as shutter seal 36 as the stirring part 33f, cap seal 37, the shutter member 34d, and a seal member, and electronic data storage medium (see
The fit of the stirring member 33f which rotate the toner container 32Y in the embodiment 3 as well as that of the embodiment 1 with the container main part 33Y is performed to bottle mouth part 33a (opening A). It is pressed fit in the bottle mouth part 33a (opening A) which two show in
As for one pair of tabular members 33f of installed to the inside of the container main part 33Y by the stirring part 33f in the embodiment 3 from the hollow part B in cap part 34Y, 1 is provided as shown in
The toner ejection characteristic from the opening A improves because the stirring part 33f is rotated with the opening A of the container main part 33Y.
As shown in
Thus, because of the extrusion plate 33f10 provided at the head of the tabular member 33f1 in the stirring part 33f, the toner is pushed to the toner outlet W in the cap part 34Y with rotation of the stirring part 33f in the extrusion plate 33f10 to prevent the toner from being blocked near the toner outlet W (the toner drop passage C), and smooth toner ejection from the toner outlet W is allowed.

As shown in (1) in
Similar to the embodiment 1, in the toner container 32Y of the embodiment 3, the positional relationship in the longitudinal direction between the cap seal 37 (which is disposed between the container main part 33Y and the cap part 34Y) and the pressing part 34c which projects on the outer circumference surface of the cap part 34Y (which projection is pressed in the direction opposite to the direction of the mounting force when the cap part 34Y is attached to the image forming device body 100) is optimized. Thereby, in the embodiment 3, the attaching/detaching operation of the toner container 34Y can be smoothly performed similar to the embodiment 1, and the sealing characteristic of the container main part 33Y and the cap part 34Y can be maintained at a high level without enlarging the cap part 34Y in size.
Embodiment 4:
The toner container 32Y in the embodiment 4 is constituted similar to that of the embodiment 3 to include the container main part 33Y (bottle body) and the cap part 34Y (bottle cap) provided in the head end of the container main part. Besides the container main part 33Y and the cap part 34Y, the toner container 32Y in the embodiment 4 is decomposed into the stirring part 33f, the cap seal 37, the shutter member 34d, the shutter seal 36 as the seal member, and the RFID chip 35 as the electronic data storage medium (see
As shown in
Unlike the embodiment 3, with reference to

Subsequently, as shown in
Subsequently, as shown in
At this time, the returning force of the elasticity of the flexible member 34u acts on the toner, and the toner collapsing and smooth toner ejection in the toner drop passage C is allowed.
The shape of the flexible member 34u is not limited to that of the embodiment 4, and a flexible member with another shape which does not have a curved part and a flexible member with a fixed part 34u2 having a different shape may be used instead.
The cap seal 37 in the embodiment 4 is installed between the container main part 33Y and the cap part 34Y, and pressed in the direction which resists the force of the mounting direction when the cap part 34Y is attached to the image forming device body 100, and the positional relationship of the longitudinal direction of the pressing part 34c which projects on the outer circumference surface of the cap part 34Y is optimized. Thereby, also in the embodiment 4, the attaching/detaching operation of the toner container 34Y can be smoothly performed like each embodiment, maintaining the high sealing characteristic of the container main part 33Y, and cap part 34Y, without enlarging cap part 34Y.
Embodiment 5:
The toner container in the embodiment 5 is arranged so that the container main part 33Y and the cap part 34Y are held to the toner container accommodating part 70 without rotation is different from that of the foregoing embodiments in which the container main part 33Y is held rotatably at the toner container accommodating part 70.
As shown in
Here, as for the toner container 32Y in the embodiment 5, unlike that of each embodiment, main part 33Y (bottle body) of a container is fixed by fixing methods, such as adhesion, fusion joining, and a stop, to cap part 34Y (bottle cap).
That is, without being connected to the cap part 34Y rotatably, the container main part 33Y is fixed so that it is not rotate relative to the cap part 34Y.
As for the container main part 33Y in the embodiment 5, unlike that of each embodiment, the spiral projection is not formed in the circumference.
The gear 33c as in the foregoing embodiment is not formed in the container main part 33Y, but the gear member 42Y (see
The cap part 34Y can be constituted almost like that of each embodiment except for the point that the container main part 33Y is stuck. The stirring member 33f can be constituted almost like that of each embodiment except for the point which is not being fixed to the container main part 33Y.
As shown in
The through hole which leads within and without the container main part 33Y is formed in 33d of this grip part, and the lid member 49Y is detachably installed therein by the through hole. The lid member 49Y fills up the inside of the toner container 32Y (the container main part 33Y) with toner in the time of manufacture or recycling.
As shown in
As for 33d of bearings, the end on the side of the direction other end of a stretcher is supported by 1 (it is a root portion which is the grip part 33d, and rotatably formed in the portion within the container main part 33Y). Where the container main part 33Y and cap part 34Y are held by non rotation at the toner container accommodating part 70, the conveyance member 41Y which is connected with the stirring part 33f in the position of 20 as for the connection part 33f will also rotate because the stirring part 33f rotate with gear member 42Y in response to driving force from actuator 91.
In this way, the toner contained in the container main part 33Y will be delivered to the cap part 34Y side by the carrying force of the flexible stirring member 41Yb installed in the conveyance member 41Y.
The flexible stirring member 41Yb of the conveyance member 41Y includes plural cut-out portions 41Ybl which are formed by cutting at plural places (in the embodiment 5, six places) in the longitudinal direction. The head end of the flexible stirring member 41Yb (which is the free end thereof not supported by the shank 41Ya) slides onto the inner circumference side of the container main part 33Y with the rotation of the conveyance member 41Y. The flexible stirring member 41Yb is rotated and moderately twisted so that the toner contained in the container main part 33Y is stirred and delivered to the right side in
In this way, in the toner container 32Y in the embodiment 5, the toner can be discharged from the toner outlet W of the cap part 34Y, similar to that of the above embodiment.
As shown in
The sealing material 40Y is formed between the gear member 42Y and the end face of the bottle mouth part 33a in order to prevent leakage of the toner to the outside of the toner container 32Y. The sealing material 40Y is formed of a foamed elastic material, such as foamed polyurethane, and has an annular configuration that matches with the end face of the bottle mouth part 33a, and the sealing material is stuck on the gear member 42Y.
When the gear member 42Y is set to the container main part 32Y, the sealing material 40Y is forced on the end face of the bottle mouth part 33a, and the sealing characteristic between the components 33Y and 42Y is increased. It is not fixed to the cap part 34Y, but the gear member 42Y is held pivotably to the claw part 34j of the cap part 34Y.
The holding method of the gear member 42Y to the cap part 34Y is the same as the holding method of the cap part 34Y to the bottle mouth part 33a of the container main part 33Y described above.
The cap seal 43Y which becomes a portion on which the end face (the container main part 33Y side is the end face of the opposite side) of the gear member 42Y is forced by the foamed elastic material is stuck on the cap part 34Y. Thereby, the leakage of the toner from the space between the gear member 42Y and the cap parts 34Y can be prevented.
The stirring member 33f is attached to the inner diameter part of the gear member 42Y. The connection part 33f20 of the stirring member 33f is connected with the shank 41Ya20 (end 41Ya1 on the side of an end) of the conveyance member 41Y 20.
In the embodiment 5, it is formed so that the toner drop passage C1 and C2 which are formed in cap part 34Y may be missing from the lower stream side (the toner outlet W) from the upstream side (the lower part of the cylindrical hollow part B) and passage area (passage sectional area) may increase gradually.
That is, compared with the passage area of the toner drop passage C1 of the vertical direction upper part, as shown in
The problem that the toner drop passage is clogged with the toner can be reduced, and smooth toner ejection from the toner outlet W is allowed.
The cap seal 37 is installed between the container main part 33Y and the cap part 34Y, pressed in the direction which resists the force of the mounting direction when the cap part 34Y is attached to the image forming device body 100, the positional relationship of the longitudinal direction of pressing part 34c which projects on the outer circumference surface of the cap part 34Y is optimized. Thereby, in the embodiment 5, the attaching/detaching operation of the toner container 34Y can be smoothly performed, and the sealing characteristic of the container main part 33Y and the cap part 34Y can be maintained at high level without enlarging the cap part 34Y.
As shown in
When the gear 44Y is rotated around the container main part 33Y, the rotating shaft 45Y and the coil 46Y are also rotated. Hence, the toner contained in the container main part 33Y is delivered to the side of the opening A by the toner delivering force of the coil 46Y.
The gear 44Y is inserted in the outer circumference part of the opening A so that the gear is sandwiched between the container main part 33Y and the cap part 34Y. The rubber member 47Y is disposed between the container main part 33Y and the gear 44Y at the end surface side, and the seal member 48Y is disposed between the cap part 34Y and the gear 44Y at the other end surface side.
By the composition, the sealing characteristic of the whole toner container 32Y is maintained. That is, the problem that toner leaks from the space between the gear 44Y, the container main part 33Y, and the cap part 34Y is prevented.
Alternatively, the toner drop passage C in the embodiments 1-4 may be formed similar to the toner drop passages C1 and C2 (see
According to the present disclosure, it is possible to provide a toner container and an image forming device wherein, even if another toner container of a different color or kind is erroneously set to dispose the other toner container in the body of the image forming device, the problem that toner of a different color or kind from the other toner container is supplied accidentally to the image forming device body is prevented.
According to the present disclosure, it is possible to provide a toner container and an image forming device wherein the shutter member that opens or closes the toner outlet is arranged so that the shutter member does not easily move when the toner container is isolated from the image forming device, and plastic deformation of the shutter member does not arise even when the state of the shutter member that opens the toner outlet is continued for a long time.
According to the present disclosure, it is possible to provide a toner container and an image forming device wherein the attaching and detaching operation of the toner container is smoothly performed and the sealing characteristic of the container main part and the cap part is maintained at high level without enlarging the cap part.
The present disclosure is not limited to the specifically disclosed embodiments, and variations and modifications may be made without departing from the scope of the present disclosure.
