Description

Process cartridge and drive assembly

Technical field

The present application relates to the field of electrostatic printing technology, and in particular, to a process cartridge and a driving assembly.

Background technique

In the prior art, the process cartridge is detachably mounted on the electronic image forming apparatus. The electronic imaging device is provided with a drive head that outputs a rotational driving force. The process cartridge generally includes a driving assembly for receiving a rotational force, a developing member, a developer, a powder controlling member, and a housing for accommodating the above-mentioned components, and additionally, a photosensitive member, a charging member, and a cleaning device are additionally provided according to different kinds of processing cartridge structures. Components and stirring elements, etc. The driving assembly of the process cartridge is disposed at one end of the process cartridge along the axial direction of the developing member or the photosensitive member, and the driving force is transmitted to the process cartridge through the driving assembly and the driving head in the electronic imaging device. The rotating elements (such as developing elements, photosensitive elements, stirring elements, etc.) inside the driving process cartridge are rotated to participate in the developing operation of the electronic image forming apparatus.

The electronic imaging device needs to install the process cartridge into the electronic imaging device before performing the developing operation (so-called "printing"), and the driving assembly of the process cartridge needs to be in contact with the driving head on the electronic imaging device to engage each other. .

As shown in Fig. 1, the process cartridge C is mounted in an electron imaging device (not shown) in the direction X (the direction X is substantially perpendicular to the axial direction of the developing member), and the process cartridge C passes through the left and right inner panels in the electronic imaging device. The guide rails (F100, F200) support and guide the process cartridge C into the electronic imaging device. When the process cartridge C is mounted into the electronic imaging device along the guide rails (F100, F200), as shown in FIG. 2, the drive assembly 100 at one end of the process cartridge C is also moved along the direction X to be in contact with the drive head 900 on the electronic imaging device. Contact engagement, due to the relative fixation of the drive head 900 in the electronic imaging device (which can only rotate along its own axis), during the movement of the drive assembly 100 in the direction X in contact with the drive head 900, the rotational power reception of the drive assembly 100 Component 110 will have a certain probability of forming structural interference with drive head 900. Therefore, in the prior art, when the rotary power receiving member 110 forms a structural interference with the drive head 900, its rotary power receiving member 110 is subjected to being pressed from the drive head 900 to be retracted inward in the axial direction. Rotating power receiver When the member 110 continues to move substantially coaxially with the driving head 900, the structural interference between the rotary power receiving member 110 and the driving head 900 disappears, and the rotational power receiving member 110 is elastically biased by the spring provided inside the driving assembly 100. The outer protrusion is in contact with the driving head 900.

However, as shown in FIG. 3 to FIG. 5, there is also an electronic imaging device in the prior art, in which one side rail F300 of the electronic imaging device is further provided with a stopper F310, which is close to the driving of the electronic imaging device. The head 900 is disposed, and the block F310 overlaps with the partial structure of the driving head 900 (having an overlapping area H) as viewed from the axial direction of the driving head 900, and the protruding end F311 of the stopper F310 covers the driving claw of the driving head 900. 910.

Thus, if the drive assembly 100 of the above configuration is used, when the process cartridge C is loaded into the electronic imaging device, the claws 111 of the drive assembly 100 directly abut against the protruding end F311 of the stopper F310 to form structural interference. Then, the rotary power receiving member 110 cannot engage with the drive head 900 in the electronic image forming apparatus to receive the driving force.

L rotation, since the limiting hole 221 of the guide sleeve 220 has been restricted by the limiting block a102 of the side plate a100 so that the guiding sleeve 220 cannot rotate relative to each other and can only move in the axial direction of the hub 250, during the rotation of the positioning ring 230 The inclined surface 232 will abut against the inclined surface 222 of the guide sleeve 220 and press the guide sleeve 220 downward to move the whole downwardly. When the guide sleeve 220 moves down, the rotary power receiving member 210 connected thereto is also moved along the axial direction thereof. The hub 250 is retracted inwardly and compresses the elastic member 281 provided in the hub 250, and the transmission member 260 connected to the end connector 213 of the rotary power receiving member 210 also moves down following the movement of the rotary power receiving member 210, and finally The gear surface 261 of the transmission member 260 is separated from the gear surface 251 at the bottom of the hub 250, and even if the power receiving portion 211 transmits the driving force to the transmission member 260, the transmission member 260 does not transmit the rotational driving force to the wheel. 250 on. Therefore, when the control mechanism When the force is not applied to the 290, the rotational power receiving member 210 is in a retracted state with respect to the hub 250 and the rotational power receiving member 210 does not transmit the driving force to the hub 250 while rotating.

When the control mechanism 290 under the action of the thrust F1, the control mechanism 290 compresses the elastic member 281 and moves forward, the connecting post 291 at the front end of the control mechanism 290 pushes the engaging hole 231 to move and rotates the positioning ring 230 as a whole in the counterclockwise direction R due to The guide sleeve 220 can only be displaced in the axial direction, and the inclined surface 232 of the rotated positioning ring 230 no longer resists the inclined surface 222 of the guide sleeve 220. At this time, the elastic member 281 disposed in the hub 250 releases the elastic force to push the rotary power receiving member 210. Extending outwardly with respect to the hub 250, while the transmitting member 260 is also moved upward with the movement of the rotary power receiving member 210, the gear surface 261 of the transmission member 260 is finally engaged with the gear surface 251 at the bottom of the hub 250. Therefore, when the control mechanism 290 is stressed, the rotational power receiving member 210 is in the extended state with respect to the hub 250 and the rotational power receiving member 210 transmits the rotational driving force to the hub 250 while rotating. When the power receiving portion 211 is outwardly extended or inwardly retracted, the rotating shaft of the power receiving portion 211 is substantially coaxial with the rotating shaft of the hub 250.

(pressure receiving surface and first moving part)

In order to better cooperate with the above-mentioned driving assembly and control mechanism 290, the process cartridge C1 is also provided with the following components:

The first housing A is provided with a first moving member. In the embodiment, the first moving member is the pressing member a200. The pressing member a200 is located at the front end of the first housing A with respect to the mounting direction of the processing cartridge C1. On the upper surface, an elastic member a200a for providing an elastic force is further provided under the pressing member a200, and the elastic member a200a can elastically move the pressing member a200 on the upper surface of the first casing A.

The second casing B is provided with a pressure receiving surface b01 which is located on the rear upper surface of the second casing B (shaded in FIGS. 7 and 8) with respect to the mounting direction of the process cartridge C1.

The first side wall b100 is provided with a pressure receiving surface b100x which is located at the rear end surface of the first side wall b100 (shaded in FIGS. 7 and 8) with respect to the mounting direction of the process cartridge C1.

The second side wall b200 is provided with a pressure receiving surface b200x which is located at the rear end surface of the second side wall b200 (shaded in FIGS. 7 and 8) with respect to the mounting direction of the process cartridge C1.

In the following, when the process cartridge C1 is loaded into the electronic image forming apparatus P, the power receiving portion 211 of the process cartridge C1 is in meshing engagement with the driving head 900 of the electronic image forming apparatus to receive the driving force for rotation, and after the meshing is completed, the power receiving portion 211 and The action process in which the driving heads 900 are separated from each other.

As shown in FIG. 15 and FIG. 16, during the mounting process of the process cartridge C1, the shell of the process cartridge C1 is removed. Viewed in the longitudinal direction of the body, the drive assembly 200 and the side plate a100 are advanced on the process cartridge C1 with respect to the mounting direction X of the process cartridge C1, and in the electronic imaging device P, the drive head 900 of the electronic imaging device is opposed to the stopper F310. Closer to the process cartridge C1, that is, the drive head 900 is disposed relatively forward, and the stopper F310 is disposed relatively rearward.

As shown in FIGS. 17 to 25, the process cartridge C1 is loaded into the electronic image forming apparatus P and the pusher a200 of the process cartridge C1 and the inner frame P2 of the electronic image forming apparatus P before the power receiving portion 211 is brought into contact with the drive head 900. The top portion is formed by pressure abutting so that the pressing member a200 integrally presses the first casing A of the process cartridge C1, and the elastic lower pressure Fd is applied, and the power receiving portion 211 is viewed from the longitudinal direction of the process cartridge C1. The position is lower than the driving head 900 as a whole, and there is a height difference H1 between the rotating shafts of the two, and the rotating shaft of the power receiving portion 211 and the rotating shaft of the driving head 900 are still parallel but deviate from each other, and the power receiving portion is at this time. 211 is in the pre-engagement position. Since the position of the claw 211a on the power receiving portion 211 is not specific, the following two positions will occur when the power receiving portion 211 is in contact with the driving head 900:

The first position, as shown in Figs. 18a and 18b, is viewed from the axial direction of the power receiving portion 211, and the highest point of the claw 211a is lower than the cylindrical body 905 of the driving head 900, that is, the claw 211a and the cylindrical body 905 are No structural interference is formed in the mounting direction X, at which time the opening 211c between the two jaws 211a is completely upward or downward. When the process cartridge C1 is mounted to a predetermined pre-engagement position in the electronic image forming apparatus P, the power receiving portion 211 is located below the drive head 900 and the stopper F310 and the rotation axis of the power receiving portion 211 is parallel to the rotation axis of the drive head 900. And deviating; and due to the orientation of the opening 211c, the downward projection surface of the cylinder 905 does not have an overlapping area with the claw 211a.

At the bottom of the process cartridge C1, there are two adjacent surfaces where there is a joint protruding from the process cartridge C1, which is located below the center of the process cartridge C1, and after the process cartridge C1 is loaded into the inner frame P2. It can reach the bottom part of the inner frame P2 and become the rotation part C1x of the process cartridge C1. When the movable door cover P1 of the electronic imaging device P is closed, the inner surface P1a of the door cover P1 is pressed against any pressure receiving surface (b01/b100x/b200x) behind the process cartridge C1 or the user directly applies a force to press the above. When the pressure receiving surface is pressed, the pressure receiving surface of the process cartridge C1 is subjected to a downward pressure Fd to cause the process cartridge C1 to rotate counterclockwise against the bottom portion of the inner frame P2 by the rotation portion C1x below the center, that is, the second casing B is subjected to The lower pressure Fd is moved downward and the first housing A is moved up by the upper thrust force Fu generated by the lower pressure Fd. As the swing of the first housing A moves up, the power receiving portion 211 moves toward the drive head 900 and pushes the member a200. Gradually in a compressed state. From the side direction of the power receiving portion 211 It is observed that during the upward movement of the power receiving portion 211, the intermediate surface 211b of the power receiving portion 211 in the inwardly retracted state does not form structural interference with the bottommost end 905a of the cylinder 905 and the side contour of the power receiving portion 211 is also There is no structural interference with the protruding end F311 of the stopper F310. Therefore, when the process cartridge C1 is rotated around the rotating portion C1x, the control mechanism 290 is also subjected to the action of the thrust F1 so that the power receiving portion 211 projects outwardly with respect to the hub 250 to engage with the driving head 900, and the power receiving portion 211 is in contact with The force transmitting position of the driving head 900 is such that the rotating shaft of the power receiving portion 211 is substantially coaxial with the rotating shaft of the driving head 900. Finally, by the driving of the driving head 900, as shown in FIGS. 24 and 25, the driving claw 910 outside the cylindrical body 905 is in contact with the claw 211a, and transmits the driving force of the rotation to the power receiving portion 211, and the power receiving portion 211 passes through The hub 250 is transferred into the process cartridge C1.

The second position, as shown in FIGS. 26 to 27b, is viewed from the axial direction of the power receiving portion 211, and in the mounting direction X, the highest point of the claw 211a forms a structural interference with the cylindrical body 905 of the drive head 900; The power receiving portion 211 is inwardly retracted, and the power receiving portion 211 is arbitrarily rotatable relative to the hub 250 without transmitting a rotational force, and thus moves to the lower side of the driving head 900 and up to the force transmitting position, the claw When the 211a and the cylinder 905 are in abutting interference, the claw 211a can be pushed to generate a partial rotation adjustment, so that the power receiving portion 211 can be rotated to the first position, and finally the driving head 900 is brought into contact. Engage.

As shown in FIGS. 28 to 30, when the user takes out the process cartridge C1 from the electronic image forming apparatus, the power receiving unit 211 and the drive head 900 are separated. During the take-out of the process cartridge C1, the control mechanism 290 will no longer be subjected to the thrust F1, and the power receiving portion 211 will return to the inwardly retracted position relative to the hub 250. However, the following two disengagement positions also occur in the power receiving portion 211:

As shown in FIG. 28, after the meshing rotation of the power receiving portion 211 and the driving head 900, as seen from the axial direction of the power receiving portion 211, the claw 211a has a certain probability of being in the driving head as it rotates. Above the cylinder 905 of 900, after the pressure receiving surface (b01/b100x/b200x) of the process cartridge C1 is no longer pressurized (opening the door cover P1), the pressing member a200 in a compressed state is released after being pressed again. The elastic force pushes the first casing A downward and rotates the process cartridge C1, but the abutment of the claw 211a against the cylinder 905 will hinder the rotation of the process cartridge C1, at which time since the claw 211a has been separated from the drive pawl 910, reference is made to the figure. 23 is shown. Thus, the user only needs to take out the process cartridge C1 from the disassembly direction, and the claw 211a does not form a cylinder 905. The structure is interfered without the power receiving portion 211 being placed under the driving head 900 by the pressing of the pressing member a200, and the process cartridge C1 is taken out.

As shown in FIG. 29 and FIG. 30, unlike the above-mentioned disengagement position, the claw 211a will have a certain probability to be on both sides of the cylinder 905 of the drive head 900 with the rotation, that is, basically the first position. Consistently, the opening 211c between the two jaws 211a is completely upward or downward. After the pressure receiving surface (b01/b100x/b200x) of the process cartridge C1 is no longer pressurized (opening the door cover P1), the pressing member a200 in the compressed state will release the elastic force to push the first casing A after being pressed. The lower movement of the process cartridge C1 is performed, and finally the power receiving portion 211 is returned to the lower side of the driving head 900 under the push of the depression force Fd. Finally, the process cartridge C1 can be taken out from the electronic image forming apparatus P.

In addition, the pressing member a200 may be disposed not only at the upper surface of the first casing A but also at the bottom surface b02 of the second casing B, that is, the rear end bottom surface of the process cartridge C1, as shown in FIG. It is shown that the pusher a200 disposed on the bottom surface b02 can be in contact with the bottom of the inner frame P2 in the electronic image forming apparatus P.

Further, the surface of the rotating portion C1x of the process cartridge C1 of the inner frame P2 is curved, or a rotating shaft rotatable around the casing may be used instead, so that the process cartridge C1 is pressed to be more flexible when the electronic image forming apparatus P rotates. smoothly.

In addition, the pressure receiving surface (b01/b100x/b200x) may be covered with a buffer layer to prevent the pressure receiving surface or the inner surface P1a of the door cover P1 from being damaged when the door cover P1 is pressed down, and the buffer layer may be a sponge. Or a felt or the like having a certain amount of elasticity or a soft material.

Further, the above elastic member (281/a200a) may be a spring, a magnet or an elastic sponge.

In the above implementation, the rotary power receiving member 210 may further be provided with a coupling function to have a certain displacement amount when the power receiving portion 211 forms a structural interference with the driving head 900, thereby further avoiding hard interference wear between the two. .

The guide key and the guide groove are also exchangeably arranged, that is, the power receiving portion 211 And/or the end connector 213 is provided with a guide groove, and the intermediate connector 212 is provided with a guide key. In addition, the guide key and the guide groove can also be arranged as a T-shaped key and a T-shaped groove structure, and the T-shaped shape has a relative limit function to prevent mutual separation between the components.

The plane moves, and the direction of the plane movement is perpendicular to the axial direction of the power receiving portion 211.

The return member 300 is used to return to the hub after the sliding displacement of the power receiving portion 211. 250 coaxial middle position. The return member 300 is preferably a tapered/tower type spring.

With the above arrangement, when the process cartridge C1 is pressed in any of the pressure receiving faces behind the process cartridge C1 in the electronic image forming apparatus P, the second half of the process cartridge C1 is pressed down, and the front half of the process cartridge C1 is pressed. The tilting power receiving portion 211 is moved up; when the pressure receiving surface is no longer pressed, the pressing member a200 of the process cartridge C1 returns the process cartridge C1 to the position before the pressing.

Piece 281 is between control mechanism 290 and side wall b100.

As shown in FIGS. 42 and 43, when the rotational power receiving member 210 mounted in the hub 250 is not restrained, the power receiving portion 211 of the rotary power receiving member 210 can be in the intermediate connector 212 and the end connector 213. With the cooperation of the projection of the cavity of the hub 250 perpendicular to the plane of the hub 250 axis, that is, any plane slip in the range enclosed by the inner wall 255.

As shown in FIGS. 44 to 47, an operation diagram in which the control mechanism 290 controls the rotary power receiving member 210 to extend outward or inwardly is shown. (In order to make the action diagram more intuitive, some parts are not shown)

When the control mechanism 290 is not under the action of the thrust F1, the elastic driving force of the elastic member 281 causes the control mechanism 290 to move backward, and the connecting post 291 at the front end of the control mechanism 290 pulls the matching hole 231 to move and the positioning ring 230 as a whole in the clockwise direction. L rotation, since the limiting hole 221 of the guide sleeve 220 has been restricted by the limiting block a102 of the side plate a100 so that the guiding sleeve 220 cannot rotate relative to each other and can only move in the axial direction of the hub 250, during the rotation of the positioning ring 230 The inclined surface 232 will abut against the inclined surface 222 of the guide sleeve 220 and press the guide sleeve 220 downward to move the whole downwardly. When the guide sleeve 220 moves down, the rotary power receiving member 210 connected thereto is also moved along the axial direction thereof. Hub 250 The elastic member 281 provided in the hub 250 is retracted inwardly and compressed, and the transmission member 260 connected to the end connector 213 of the rotary power receiving member 210 is also moved downward following the movement of the rotary power receiving member 210, and finally the transmission member The gear surface 261 of the 260 is separated from the gear surface 251 at the bottom of the hub 250, and even if the power receiving portion 211 transmits the driving force for the rotation to the transmission member 260, the transmission member 260 does not transmit the rotational driving force to the hub 250. . Therefore, when the control mechanism 290 is not stressed, the rotational power receiving member 210 is in a retracted state with respect to the hub 250 and the rotational power receiving member 210 does not transmit the driving force to the hub 250 while rotating.

When the control mechanism 290 under the action of the thrust F1, the control mechanism 290 compresses the elastic member 281 and moves forward, the connecting post 291 at the front end of the control mechanism 290 pushes the engaging hole 231 to move and rotates the positioning ring 230 as a whole in the counterclockwise direction R due to The guide sleeve 220 can only be displaced in the axial direction, and the inclined surface 232 of the rotated positioning ring 230 no longer resists the inclined surface 222 of the guide sleeve 220. At this time, the elastic member 281 disposed in the hub 250 releases the elastic force to push the rotary power receiving member 210. Extending outwardly with respect to the hub 250, while the transmitting member 260 is also moved upward with the movement of the rotary power receiving member 210, the gear surface 261 of the transmission member 260 is finally engaged with the gear surface 251 at the bottom of the hub 250. Therefore, when the control mechanism 290 is stressed, the rotational power receiving member 210 is in the extended state with respect to the hub 250 and the rotational power receiving member 210 transmits the rotational driving force to the hub 250 while rotating.

As shown in FIGS. 48 to 53, a schematic diagram of the relative displacement of the power receiving portion 211 of the rotary power receiving member 210 by the control mechanism 290 and the reset member 282 is performed.

As shown in FIG. 48 to FIG. 50, when the control mechanism 290 is not under the action of the thrust F1, the control mechanism 290 is relatively rearward, and the first abutting surface 292a of the pushing portion 292 at the front end of the control mechanism 290 is moved to the power receiving portion. At the lower side of the 211, the restoring member 282 abuts against the connecting post 211x of the power receiving portion 211 and presses down the power receiving portion 211 by releasing the elastic force, since the power receiving portion 211 can be performed in the inner wall 255 of the cavity. The plane is slipped, and the depression of the pushing end 282x causes the power receiving portion 211 to be displaced downward by a certain distance, and is supported by the first abutting surface 292a of the pushing portion 292. After the power receiving portion 211 is displaced downward, the power receiving portion The axis of rotation of 211 is offset and parallel with respect to the hub 250 and the axis of rotation of the drive head 900, in a pre-engaged position. At the same time, the power receiving portion 211 is also in a state of being inwardly retracted with respect to the hub 250.

As shown in FIG. 51 to FIG. 53, when the control mechanism 290 is moved by the thrust F1, the control mechanism 290 moves forward, and at this time, the power receiving portion 211 abutting on the first abutting surface 292a follows The forward movement of the control mechanism 290 is pushed by the inclined surface 292c behind the first abutting surface 292a and cancels the thrust applied by the resetting member 282 to form an upward movement, and finally the second abutting surface which is at a higher position with respect to the first abutting surface 292a. The 292b moves to the lower side of the power receiving portion 211 and supports the connecting post 211x of the power receiving portion 211, and the pushing end 282x against the connecting post 211x is in a compressed state at this time. After the power receiving portion 211 is displaced upward, the rotation shaft of the power receiving portion 211 is at a force transmission position substantially coaxial with respect to the rotation axis of the hub 250. At the same time, the power receiving portion 211 is also in an outwardly projecting state with respect to the hub 250.

As described above, when the control mechanism 290 of the process cartridge C1 is not pushed by the thrust F1, the reset member 282 pushes the power receiving portion 211 downward, the power receiving portion 211 is in the pre-engagement position, and the rotating shaft of the power receiving portion 211 is opposed to the hub 250. The rotating shaft is offset and parallel; and when the control mechanism 290 of the process cartridge C1 is pushed by the thrust F1, the second abutting surface 292b of the control mechanism 290 pushes the power receiving portion 211 upward, and the power receiving portion 211 is at the force transmitting position. The rotation shaft of the power receiving portion 211 is substantially coaxial with respect to the rotation axis of the hub 250.

Further, referring to FIG. 1, FIG. 50, and FIG. 53, when the process cartridge C1 is mounted in the mounting direction X into the electronic image forming apparatus, the position of the power receiving portion 211 at the pre-engagement position is higher than that of the power receiving portion 211 at the force transmitting position. Low, the power receiving portion 211 at the pre-engagement position is below the power receiving portion 211 at the force transmitting position; and the moving direction when the power receiving portion 211 at the force transmitting position is moved to the pre-engaging position by the thrust of the reset member 282 is Gravity direction.

Hereinafter, when the process cartridge C1 is loaded into the electronic image forming apparatus (not shown), the power receiving portion 211 of the process cartridge C1 is in contact with the driving head 900 of the electronic image forming apparatus to receive the driving force of the rotation, and the power receiving after the meshing is completed. The operation of the portion 211 and the drive head 900 are separated from each other.

Referring to Fig. 1 and as shown in Figs. 36 and 54, in the mounting process of the process cartridge C1, the drive assembly 200 and the side plate a100 are advanced on the process cartridge C1 with respect to the mounting direction X of the process cartridge C1. When the process cartridge C1 is mounted to a predetermined position in the electronic image forming apparatus, at this time, the power receiving portion 211 is located below the driving head 900, and before the control mechanism 290 is subjected to the thrust F1, the power receiving portion 211 is in the pre-engagement position and relative to the hub The 250 is in the inwardly retracted state, and thus the following two meshing states occur when the power receiving portion 211 is in contact with the driving head 900:

In the engaged state, as shown in FIGS. 54 to 56, the downward projection surface of the cylinder 905 of the drive head 900 is not aligned with the power receiving portion 211 as viewed in the axial direction of the power receiving portion 211. The claws 211a of the end overlap, that is, the claw 211a does not interfere with the cylinder 905 as the power receiving portion 211 moves upward; and at the same time, the power receiving in the inwardly retracted state as viewed from the side direction of the power receiving portion 211 The intermediate surface 211b of the portion 211 does not form structural interference with the bottommost end 905a of the cylinder 905 and the side profile of the power receiving portion 211 does not form structural interference with the protruding end F311 of the stopper F310. Therefore, when the user or the mechanism of the electronic imaging device applies force to the control mechanism 290, the power receiving portion 211 in the above-described meshing state 1 causes the power receiving portion 211 to be opposed to the hub under the push control of the thrust mechanism F1 by the control mechanism 290. 250 is outwardly extended and moved upward and the power receiving portion 211 is in the force transmitting position. Finally, by the driving of the driving head 900, as shown in FIGS. 59 and 60, the driving claw 910 outside the cylinder 905 is in contact with the claw 211a. The meshing transmits the driving force of the rotation to the power receiving portion 211, and the power receiving portion 211 is thereby transmitted to the process cartridge C1 through the hub 250.

In the meshing state 2, as shown in FIGS. 57 and 58, the downward projection surface of the cylindrical body 905 of the drive head 900 overlaps with the claw 211a at the top end of the power receiving portion 211 as viewed in the axial direction of the power receiving portion 211. That is, the claw 211a will interfere with the cylinder 905 with the upward movement of the power receiving portion 211; since the power receiving portion 211 is in the pre-engagement position, the power receiving portion 211 can arbitrarily rotate with respect to the hub 250 without transmitting the rotational force. Therefore, when the abutting interference occurs, the claw 211a can be abutted by the rounded surface of the cylinder 905 during the upward movement to cause a partial rotation adjustment of the claw 211a, so that the power receiving portion 211 can be in the above state. In the case, finally, the contact with the driving head 900 is achieved.

As shown in FIG. 61 to FIG. 62, when the user takes out the process cartridge C1 from the electronic image forming apparatus, the power receiving unit 211 and the drive head 900 are separated. During the take-out of the process cartridge C1, the control mechanism 290 will no longer be subjected to the thrust F1, and the reset member 282 pushes the power receiving portion 211 at the force transmitting position back to the pre-engagement position. However, in the process of returning the power receiving portion 211 to the pre-engagement position, the power receiving portion 211 also exhibits the following two separated states:

In the separated state, as shown in FIG. 61 and FIG. 63, after the meshing rotation of the power receiving portion 211 and the driving head 900, the claw 211a has a certain probability of being rotated as viewed from the axial direction of the power receiving portion 211. Above the cylinder 905 of the driving head 900, in the process of returning the power receiving portion 211 to the pre-engagement position, the upper jaw 211a will move directly against the cylinder 905 without being pushed by the reset member 282, and cannot Continue moving down, even if power is received The portion 211 cannot continue to move downward due to interference, but the power receiving portion 211 has been inwardly retracted relative to the hub 250 under the control of the control mechanism 290. Therefore, as seen from the side direction of the power receiving portion 211, as shown in FIG. 56, the claw 211a is retracted inwardly to be separated from the driving claw 910. Thus, the user only needs to take out the process cartridge C1 from the disassembly direction, and the claw 211a does not interfere with the cylinder 905, so that the power receiving portion 211 can be taken out as a whole, and finally the claw 211a is not blocked by the cylinder 905. In the case of the downward movement, the power receiving unit 211 returns to the pre-engagement position.

In the separated state 2, as shown in FIG. 62 to FIG. 63, unlike the above-described separated state, the claws 211a will have a certain probability to be on both sides of the cylinder 905 of the driving head 900 with the rotation, and the power receiving portion 211 recovers. When the pre-engagement position is inwardly retracted relative to the hub 250, the power receiving portion 211 can be smoothly moved below the drive head 900 and the claw 211a does not interfere with the structure of the cylinder 905. Finally, the process cartridge C1 can be taken out of the electronic image forming apparatus.

In the above-described embodiment, the pre-meshing position of the power receiving portion 211 may also be referred to as a first position, and the force transmitting position of the power receiving portion 211 may also be referred to as a second position.

In the above embodiment, the above-mentioned reset member 282 may be selected not only by a torsion spring but also by an elastic sponge, a spring or a magnet. As long as the power receiving portion 211 can be pushed from the force transmitting position/second position to the pre-engaging position/first position.

Further, the above elastic member may be a spring, a magnet or an elastic sponge.

Embodiment 3

As shown in FIG. 64, a schematic structural view of a process cartridge C3 used in the present embodiment, the process cartridge C3 includes a casing (a first casing A and a second casing B) and side walls cB1 and cB2 at both ends of the casing. The charging member 20, the cleaning member 40, the photosensitive member 10, and the like are housed in the first casing A, and the developing member 30, the powder controlling member 50, the developer, and the like are housed in the second casing B.

As shown in FIGS. 64 and 65, the drive unit c200a is disposed at one end of the process cartridge C3, and the drive unit c200a is engaged with the drive head 900 of the electronic image forming apparatus to transmit the rotational driving force to the process cartridge C3 and drive the process cartridge C3. The inner rotating member (such as the developing member 30, the photosensitive member 10, etc.) is operated to participate in the developing operation.

On the other hand, the power receiving unit c210 can expand and contract further in the axial direction of the hub c250 with respect to the rotational power receiving member main body c200b while expanding and contracting with the rotational power receiving member main body c200b. When it is necessary to detach (take out) the process cartridge C3 from the new electronic image forming apparatus, the two stages of the rotary power receiving member main body c200b and the power receiving portion c210 are contracted inward, so that the power receiving portion c210 can be disengaged from the driving head 900. The position is such that the power receiving portion c210 interferes with the driving head 900 during the loading and unloading process, thereby hindering the disassembly process.

In view of safety factors, it is preferable to allow the rotary power receiving member main body c200b to protrude first while the contact engagement is being performed, and the power receiving portion c210 is extended thereafter. Conversely, in the process of disengaging, it is preferable to allow the power receiving portion c210 to be inwardly retracted, and the rotary power receiving member main body c200b is inwardly retracted thereafter. This makes it possible to give more sufficient protection to the power receiving unit c210.
