In the image forming apparatus provided in Example 2, the tray support member is slid to a minimum structural schematic view. 3 to 5 show a perspective view of one side of the main body, and the side inner wall is provided with a rotational force transmitting member 14, and a rotational force receiving member 8 is provided at one end of the process cartridge 20.

As shown in FIG. 3 to FIG. 5, the present embodiment is specifically described by taking a rotational force receiving member 8 provided on the process cartridge 20, and the rotational force receiving member 8 is disposed at the end portion of the process cartridge 20 in the longitudinal direction, and The rotating member in the process cartridge 20 is connected, for example, to a photosensitive member provided as one of the rotating members along the longitudinal direction of the process cartridge. Four process cartridges 20 are mounted on the process cartridge tray 5, and correspondingly, four rotational force transmitting members 14 are provided on one inner wall of the main body 10.

A tray support member 13 slidable longitudinally along the inner wall is disposed on one inner wall of the main body 10, and the process cartridge tray 5 is laterally insertably mounted on the tray support member 13. The longitudinal direction is the up and down (ie, Z and -Z) directions in FIGS. 3 to 5, and The lateral direction is the left and right (ie, X and -X) directions in FIGS. 3 to 5, that is, the tray support 13 is slidable up and down along the side wall of the main body 10, and the process cartridge tray 5 is slidable left and right along the side wall of the main body 10. . The process cartridge tray 5 can be laterally inserted and disposed on the tray support 13 so that the tray support 13 drives the process cartridge tray 5 to slide longitudinally together.

The tray support member 13 is specifically a side plate, and a groove matching the process cartridge tray 5 is opened inside the side plate, and the process cartridge tray 5 can slide laterally in the groove. This groove serves as a limit to the longitudinal direction of the process cartridge tray 5, avoiding longitudinal displacement of the process cartridge tray 5 relative to the tray support 13.

A pushing member is further provided on one inner wall of the main body 10 for pushing the tray support 13 to move longitudinally. The pushing member may specifically be a movable sliding plate 15 which is slidable along the inner wall of the main body 10, and the upper surface of the movable sliding plate 15 is provided with a first slope portion 151. During the lateral sliding of the movable slide 15 along the inner wall, the first slope 151 guides the lower surface of the tray support 13 to longitudinally slide the tray support 13.

The upper surface of the movable sliding plate 15 not only has a first slope section, but also has a low section at the lowest point of the first slope section, and a high section is extended at the highest point of the first slope section, so that the upper surface of the movable sliding plate 15 The surface is in a state of high and low transition.

In addition, the first slope segment 151 may be a flat surface or a curved surface. Referring to Figures 3 to 5, the upper surface of the movable slide 15 is a wavy curved surface. Correspondingly, the lower surface of the tray support 13 is also disposed as a wavy curved surface, that is, the lower surface of the tray support 13 is provided with the second slope portion 132, and corresponds to the changing trend of the first slope portion 151. During the lateral sliding of the movable slide 15, when the highest point of the movable slide 15 comes into contact with the highest point of the tray support 13, the tray support 13 is located at the lowest position in the longitudinal direction; and when the movable slide 15 continues to slide, the wave The first slope 151 on the curved surface guides the second slope 132 of the tray support 13, pushing the tray support 13 upward, until the highest point of the tray support 13 is in contact with the lowest point of the tray support 13. At this time, the tray support 13 reaches the highest position.

The chute 16 also limits the movement of the movable slide 15 itself in the longitudinal direction. Further, a pulley 152 may be disposed at the bottom of the movable sliding plate 15, and the movable sliding plate 15 is laterally slid by the rolling of the pulley 152 with respect to the sliding groove 16, so that the frictional force can be reduced, so that the movable sliding plate 15 slides more smoothly.

The lateral sliding of the pushing member can be realized by the user manually or by an automatic method. Specifically, the connecting member is connected between the pushing member and the door cover 11 through the connecting member, so that the door cover 11 and the pushing member are in a linkage action mode. Specifically, referring to FIG. 3 to FIG. 5, the connecting member is specifically a connecting rod, which is referred to as a fourth connecting rod 12. One end of the fourth connecting rod 12 is hinged to the door cover 11 and the other end is hinged to the movable sliding plate 15, and is hinged. The position can be set with reference to the figure. During the opening of the door cover 11, the movable slide 15 is pulled to slide in the direction of the outside of the main body 10, and during the process of closing the door cover 11, the activity is pushed. The slider 15 slides in the direction of the inside of the main body 10.

The working process of the above image forming apparatus is as follows:

During the opening of the door cover 11, the movable slide 15 is pulled by the fourth link 12 to slide outside the main body 10; between the first slope 151 on the movable slide 15 and the second slope 132 on the tray support 13. In interaction, the movable slider 15 pushes the tray support 13 up to the highest position, so that the rotational force receiving member 8 on the process cartridge 20 and the rotational force transmitting member 14 on the inner wall of the main body 10 are separated. The process cartridge tray 5 can then be withdrawn from the body 10 as shown in FIG.

Then, the process cartridge 20 in which the developer is exhausted is taken out, the new process cartridge 20 is loaded into the process cartridge tray 5, and the process cartridge tray 5 is pushed into the main body 10. At this time, the rotational axis of the rotational force receiving member 8 on the process cartridge 20 is in the same vertical plane as the rotational axis of the corresponding rotational force transmitting member 14 on the main body 10, and the rotational force receiving member 8 is located at the rotational force transmitting member 14. Just above it, as shown in Figure 4.

Finally, during the closing of the door cover 11, the movable slide 15 is pushed through the fourth link 12 to slide inside the main body 10; through the first slope 151 on the movable slide 15 and the second slope 132 on the tray support 13. In the interaction, the tray support 13 is moved downward until reaching the lowest position, so that the rotational force receiving member 8 is engaged at the rotational force transmitting member 14, as shown in FIG.

Based on the above technical solution, an upper limit portion 22 may be provided in the main body 10 for limiting the highest position of the tray support member 13. The upper limit portion 22 may specifically adopt a torsion spring, and the spring portion thereof is disposed on a rotating shaft fixed to the upper portion of the main body 10. One end of the torsion spring abuts against the main body 10, and the other end abuts against the upper surface of the tray support member 13. Limiting the upward sliding displacement of the tray support 13 helps to stabilize the power transmission of the process cartridge in the working state.

In addition, unlike the implementation of the tray support 13 described above, when the process cartridge tray 5 is inserted into the main body 10, the tray support 13 may also be a support block located below both sides of the process cartridge tray 5, and the support block is pushed by the pusher. Sliding in the longitudinal direction can also drive the process cartridge tray 5 to move longitudinally. Alternatively, the tray support 13 described above can also be implemented in other ways.

For the implementation of the first slope section 151 and the second slope section 132 described above, in addition to the structure shown in FIGS. 3 to 5, other manners may be implemented. E.g:

The first type: FIG. 6 is a schematic structural view of the tray supporting member and the pushing member in the image forming apparatus provided in the second embodiment. As shown in FIG. 6, the upper surface of the movable slide 15 is provided with a first slope 151, and the first slope 151 is located at an end of the movable slide 15 toward the inside of the main body 10. The lower surface of the tray support 13 is flat, that is, the second slope portion 132 is not provided.

The second type: FIG. 7 is a structure in which the tray support member and the pushing member cooperate with each other in the image forming apparatus provided in the second embodiment. Figure 2. As shown in FIG. 7, on the basis of the first aspect, a second slope portion 132 is provided at a lower corner of the tray support 13.

The third type: FIG. 8 is a schematic structural view 3 of the image forming apparatus provided in the second embodiment, in which the tray support member and the pushing member cooperate with each other. As shown in FIG. 8, the upper surface of the movable sliding plate 15 is provided with a first slope section 151, and the first slope section 151 is a plane, and the lowest point extends with a low section, and extends at the highest point of the first slope section 151. High section. Correspondingly, the lower surface of the tray support 13 is provided with a second slope portion 132 corresponding to the first slope segment 151.

Of course, those skilled in the art can easily think of the same purpose by changing the shape of the lower bottom surface of the tray support and the upper surface of the movable slide according to the content of the present invention.

Alternatively, those skilled in the art may use other means instead of the above implementation to push the pusher member to slide longitudinally during the lateral sliding process.

Based on the above technical solution, the process cartridge tray 5 can also be improved:

As shown in Fig. 3, the process cartridge tray 5 includes a chassis 52 disposed in the lateral direction and a side edge 53 disposed in the longitudinal direction. The side edge 53 is fixed to the periphery of the chassis 52, and the process cartridge 20 is mounted around the chassis 52 and the side edge 53. Within the area. If the height of the side edge 53 is below the rotational force receiving member 8, the process cartridge 20 is mounted in the process cartridge tray 5, and the rotational force receiving member 8 projects from above the side edge 53 to the process cartridge tray 5, and further to the rotational force transmitting member. 14 meshing.

As shown in FIG. 3 to FIG. 5, if the height of the side edge 53 is above the rotational force receiving member 8, a longitudinally extending escape groove 51 may be opened downward at the top end of the side edge 53 to enable the rotational force receiving member 8 to The escape groove 51 extends out of the process cartridge tray 5.

Based on the above technical solution, the tray support 13 can also be improved:

If the tray support 13 is a support block located below both sides of the process cartridge tray 5, or if the height of the tray support 13 is lower than the rotational force transmitting member 14, the rotational force transmitting member 14 can normally engage with the rotational force receiving member 8.

As shown in FIG. 3 to FIG. 5, if the height of the tray support 13 is higher than the rotational force transmitting member 14, an elongated hole 131 extending in the longitudinal direction of the main body is required to be provided on the tray support 13 so that the rotational force transmitting member 14 is worn. The long hole 131 is passed through and meshed with the rotational force receiving member 8. Also, the long hole 131 and the rotational force transmitting member 14 are relatively slidable during the sliding of the tray support 13 in the longitudinal direction.

The number of the tray support members 13 may be two, which are respectively located on the inner walls of both sides of the main body 10, and guide and support the process cartridge tray 5 from both sides. Only one side of the tray support 13 is shown in Figures 3 to 5 . Correspondingly, the number of the pushing members is also two, which are respectively located on the inner walls of the two sides of the main body 10, respectively pushing the two tray supporting members 13 to slide longitudinally.

On the basis of the above technical solutions, the implementation of the rotational force receiving member 8 and the rotational force transmitting member 14 is advanced. Detailed description of the line:

The rotational force receiving member 8 is fixedly coupled to the photosensitive member in the process cartridge 20, the rotational axes of the two are collinear, and the end portion of the rotational force receiving member 8 is provided with a claw portion. Correspondingly, the rotational force transmitting member 14 is fixed to the inner wall of the main body 10, the rotation axis thereof is perpendicular to the inner wall, and the end of the rotational force transmitting member 14 is provided with a transmitting portion. The engagement of the claw portion with the transmission portion realizes that the rotational force transmitting member 14 is collinear with the rotational axis of the rotational force receiving member 8, and the rotational force transmitting member 14 can drive the rotational force receiving member 8 to rotate.

9 is a schematic structural view of a process cartridge in an image forming apparatus according to a second embodiment, and FIG. 10 is a schematic structural view of a rotational force receiving member in the image forming apparatus provided in the second embodiment. As shown in FIGS. 3, 4, 5, 9, and 10, one end of the rotational force receiving member 8 is provided as a universal joint, and the universal joint is connected to the end of the photosensitive member so that the rotational force receiving member 8 is provided with claws. The other end of the portion 81 is deflectable with respect to the rotational axis of the photosensitive member and is deflectable downward by gravity.

The process cartridges 20 are loaded into the process cartridge tray 5, and the rotational force receiving members 8 in each of the process cartridges 20 are all deflected downward by gravity. Fig. 11 is a view showing a position in which the rotational force receiving member is descending in the image forming apparatus according to the second embodiment, and Fig. 12 is a plan view showing the rotational force transmitting member in Fig. 11. As shown in FIGS. 11 and 12, in the process of the downward movement of the rotational force receiving member 8 in the longitudinal direction, the side of the rotational force receiving member 8 close to the rotational force transmitting member 14 and the free end portion of the rotational force transmitting member 14 are avoided. In the process in which the rotational force receiving member 8 gradually approaches the rotational force transmitting member 14, the free end portion of the rotational force transmitting member 14 interferes with a portion of the end portion of the rotational force receiving member 8, and the rotational force transmitting member 14 is not fixed. With the installation of the process cartridge, the rotational force receiving member 8 which is biased downward by gravity acts upward.

When the process cartridge is installed in place, as shown in FIG. Fig. 13 is a view showing the structure of the image forming apparatus of the second embodiment which is engaged with the rotational force transmitting member. When the process cartridge tray 5 continues to descend, the rotational force receiving member 8 is swung until its rotational axis is collinear with the rotational axis of the rotational force transmitting member 14, and the claw portion 81 is engaged with the transmitting portion 141, so that the rotational force transmitting member 14 The rotation can drive the rotational force receiving member 8 to rotate.

Fig. 14 is a view showing the position of the upward rotation of the rotational force receiving member in the image forming apparatus provided in the second embodiment. As shown in Fig. 14, during the process in which the process cartridge tray 5 is gradually raised, the rotational force receiving member 8 is deflected downward by the action of gravity, and the upward movement of the transmission portion 141 is avoided.

The technical solution provided by the embodiment only needs the tray support capable of longitudinal sliding and the pusher capable of sliding the tray support, so that the rotational force transmitting member and the rotational force receiving member can be engaged, and the rotational force receiving member is passed through The knuckle is connected to the photosensitive member in the process cartridge, and can avoid the transmission portion in the rotational force transmitting member during the process of lowering the process cartridge, and can smoothly mesh regardless of the angle at which the drive lever is located, thereby further simplifying the image shape. The internal structure of the device does not require the installation of many components. In particular, in the color image forming apparatus, the number of component structures is proportionally reduced, the manufacturing complexity is greatly reduced, the manufacturing efficiency is improved, and the cost can be reduced.

The other end of the second link 192 is hinged to one end of the third link 193, and the other end of the third link 193 is hinged to the main body 10. The three links and the main body 10 constitute an unstable quadrilateral structure, and the first link 191 and the third link 193 are laterally oscillated with respect to the hinged ends of the main body 10, and the height of the second link 192 is changed.

As shown in Fig. 15, the first link 191 and the third link 193 extend in the longitudinal direction, at which time the second link 192 is at the highest point. The second link 192 can push and support the tray support 13 to its highest position.

As shown in FIG. 16, the first link 191 and the third link 193 are oscillated clockwise, and the height of the second link 192 is lowered, and the tray support 13 is slid down to the lowest position to allow the rotational force receiving member 8 to rotate. The force transmitting member 14 is engaged.

The technical solution provided by the embodiment only needs the tray support capable of longitudinal sliding and the pushing member capable of sliding the tray support, so that the rotational force transmitting member and the rotational force receiving member can be engaged, and the link mechanism is used as the pushing member. Further, the internal structure of the image forming apparatus is further simplified, and it is not necessary to provide a large number of components. In particular, in the color image forming apparatus, the number of component structures is proportionally reduced, the manufacturing complexity is greatly reduced, the manufacturing efficiency is improved, and the cost can be reduced.

On the basis of the above technical solution, a lower limit portion for restricting the lowest position of the tray support 13 may be provided in the main body 10 to ensure that when the tray support 13 falls to a position in contact with the lower limit portion, the rotational force receiving member 8 and The rotational axes of the rotational force transmitting members 14 are collinear.

Further, the first The upper portion of the restricting portion 23 is provided as a slope toward the surface of the link mechanism, and can also limit the link mechanism during the clockwise swing to limit the swing amplitude of the link mechanism.

The number of the second lower limit portions 21 may also be two, which are respectively located on the side walls provided on both sides of the main body 10 to support and limit the tray support 13 . The upper surfaces of the first lower limit portion 23 and the second lower limit portion 21 are located on the same horizontal line.

In addition, the above-mentioned link mechanism may also be connected to the door cover 11 through a connecting member, and the connecting member is respectively hinged with the link mechanism and the door cover 11 to form a linkage relationship between the door cover 11 and the link mechanism, and the door cover 11 is opened or Closing directly drives the linkage mechanism. Specifically, the connecting member is a fifth connecting rod 18, one end of which is hinged to the door cover 11 and the other end is hinged with the first connecting rod 191, and the hinged position can be set with reference to the figure, and the door cover 11 is opened. During the process, the first link 191 is pulled to rotate counterclockwise, and the third link 193 is driven to swing counterclockwise, so that the second link 192 is raised to push the tray support 13 to rise. During the closing of the door cover 11, the first link 191 is pushed to swing clockwise, and the third link 193 is caused to swing clockwise, so that the second link 192 is lowered, and the tray support 13 is lowered by gravity. The number of the fifth links 18 may be two and symmetrically hinged on both sides of the door cover 11.

The working process of the above image forming apparatus is as follows:

During the opening of the door cover 11, the link mechanism is pulled counterclockwise by the fifth link 18, and the tray support 13 is pushed up to the highest position, so that the rotational force receiving member 8 and the main body 10 on the process cartridge 20 The rotational force transmitting member 14 on the inner wall is separated. The process cartridge tray 5 can then be withdrawn from the body 10.

The user can take out the process cartridge 20 in which the developer is exhausted, load the new process cartridge 20 into the process cartridge tray 5, and push the process cartridge tray 5 into the main body 10. At this time, the rotational axis of the rotational force receiving member 8 on the process cartridge 20 is in the same vertical plane as the rotational axis of the corresponding rotational force transmitting member 14 on the main body 10, and the rotational force receiving member 8 is located at the rotational force transmitting member 14. Just above it, as shown in Figure 15.

Finally, during the closing of the door cover 11, the link mechanism is urged to swing clockwise by the fifth link 18, and the tray support 13 is moved downward until reaching the lowest position, so that the rotational force receiving member 8 is located at the rotational force transmitting member 14.

When the force in the axial direction acts, it can be expanded and contracted. Therefore, when the process cartridge 20 is controlled by the pusher, the rotational force receiving member 8 is caused to slide downward, the end of the rotational force receiving member 8 abuts against the rotational force transmitting member 14, and the rotational force transmitting member 14 is caused to retract. When the process cartridge 20 is mounted in position, the rotational force transmitting member 14 is extended by the resilience of the elastic member 17, and is engaged with the rotational force receiving member 8. Here, the outer side surface of the claw portion 81 of the rotational force receiving member 8 has an arc shape for facilitating retraction of the rotational force transmitting member 14.

The door cover is connected such that the opening or closing of the door cover can directly control the disengagement or engagement of the rotational force transmitting member and the rotational force receiving member, further simplifying the internal structure of the image forming apparatus without requiring more components to be disposed. In particular, in the color image forming apparatus, the number of component structures is proportionally reduced, the manufacturing complexity is greatly reduced, the manufacturing efficiency is improved, and the cost can be reduced.

It is fixed to the end of the process cartridge 20, and the other free end is in contact with at least the outer surface of the rotational force receiving member 8 of the end of the process cartridge 20, and the torsion spring member 19 applies an elastic force to the rotational force receiving member 8 to cause rotation. The force receiving member 8 is always inclined in one direction. Other reference numerals in Fig. 18 can be referred to the above embodiment.

Fig. 19 is a view showing the structure of the process cartridge tray which is not pushed into the main body in the image forming apparatus provided in the fifth embodiment. The structure of the image forming apparatus in the present embodiment is simpler. Referring to Fig. 19, a plurality of rotational force transmitting members 14 are provided side by side on the inner side wall of the image forming apparatus main body 10, and the rotational force transmitting member 14 and the driving in the image forming apparatus are provided. Motor company The rotary power is transmitted by engagement with the rotational force receiving member 8 on the process cartridge 20.

The main body 10 of the image forming apparatus includes a process cartridge tray 5 slidably inserted into the main body 10 in the lateral direction of the main body 10, and a plurality of process cartridges 20 can be mounted on the process cartridge tray 5. A slide 150 is disposed in the lateral direction of the main body 10. One of the functions of the slide 150 is to guide the lateral sliding of the process cartridge tray 5, and the other is to support the process cartridge tray 5, and to limit the process cartridge tray 5 in the longitudinal direction. activity.

The processing cartridge tray 5 is provided with a relief groove 51 of the rotational force receiving member 8, which is different from the above-described embodiment in that the configuration of the escape groove 51 is different in the present embodiment. In this embodiment, the escape groove 51 includes two portions of a longitudinal groove and a transverse groove, and the longitudinal groove and the lateral groove form a T shape. Wherein, the longitudinal grooves extend in the longitudinal direction (the Z direction in the drawing), and the rotation force receiving member 8 is longitudinally avoided during the process of loading the process cartridge 20 into the process cartridge tray 5; and the lateral grass is in the lateral direction (the illustration X) In the process of pushing the process cartridge tray 5 into the main body 10, the rotation force receiving member 8 is avoided, and the swing of the rotational force receiving member 8 is not hindered.

In the embodiment of the present invention, the rotational force transmitting member 14 provided on the inner wall of the image forming apparatus main body 10 is disposed to be retractable in the direction of its rotation axis so as to smoothly mesh with and disengage from the rotational force receiving member 8 on the process cartridge 20.

Preferably, in the present embodiment, the elastic member 17 is provided at the end of the rotational force transmitting member 14, and an elastic force can be applied thereto in the direction of the rotational axis of the rotational force transmitting member 14. See the schematic of Figure 17. A compression spring can be used for the elastic member 17.

20 is a first schematic diagram of a process of pushing a process cartridge tray into a main body in the image forming apparatus provided in the fifth embodiment, and FIG. 21 is a second schematic diagram of a process of pushing the processing cartridge tray into the main body in the image forming apparatus provided in the fifth embodiment, and FIG. The image forming apparatus provided in Example 5 is a schematic structural view in which the process cartridge tray is completely pushed into the main body. 19 shows that the process cartridge tray 5 has not been pushed into the image forming apparatus main body 10, and FIGS. 20 to 22 show the process of pushing the process cartridge tray 5 into the image forming apparatus main body 10, the process cartridge 20 The meshing force of the upper rotational force receiving member 8 and the rotational force transmitting member 14.

Referring to Figs. 20 to 22, the process cartridge tray 5 is provided with four process cartridges 20, and the color of the developer contained in each of the process cartridges 20 is different. The rotational force receiving members 8 provided at the ends of the four process cartridges 20 are sequentially labeled as 8a, 8b, 8c, 8d; and correspondingly, four rotational force transmitting members 14 are provided on the main body 10, which are sequentially labeled as 14a, 14b, 14c. And 14d, wherein the rotational force receiving members 8a, 8b, 8c, and 8d are respectively engaged with the rotational force transmitting members 14a, 14b, 14c, and 14d.

As shown in Fig. 20, in the process of advancing the process cartridge tray 5 in the lateral direction, in the lateral direction, the rotation force receiving member 8 near the main body 10 and the rotation near the entrance of the main body 10 (i.e., near the door cover 11) The force transmitting member 14 is engaged first, for example, the rotational force receiving member 8d is first engaged with the rotational force receiving member 14a.

As shown in Fig. 21, as the process cartridge tray 5 continues to advance, the rotational force receiving member 8d is disengaged from the rotational force transmitting member 14a. Then, the rotational force receiving member 8d is sequentially engaged with the rotational force transmitting members 14b, 14c, and then disengaged; and the rotational force receiving member 8c is sequentially engaged with the rotational force transmitting members 14a, 14b, and then disengaged; and the rotational force is received. The member 8b will be meshed with the rotational force transmitting member 14a and then disengaged.

When the process cartridge tray 5 is mounted in position, the rotational force receiving members 8a, 8b, 8c, 8d are engaged with the rotational force transmitting members 14a, 14b, 14c, 14d, respectively, as shown in FIG.

23 is a schematic structural view showing the non-engagement of the rotational force receiving member and the rotational force transmitting member in the process of pushing the process cartridge tray into the main body according to the fifth embodiment, and FIG. 24 is a process of pushing the processing cartridge tray into the main body according to the fifth embodiment. A schematic structural view of a medium rotational force receiving member engaged with a rotational force transmitting member. As shown in FIG. 23, the direction indicated by X is the mounting direction of the process cartridge tray 5, that is, the direction in which the main body 10 is pushed. Taking the rotational force receiving member 8d and the rotational force transmitting member 14d as an example, the rotational force receiving member 8d is inclined toward the rotational force transmitting member 14d by the torsion spring member 19. The free end portion of the rotational force receiving member 8d is provided with the claw portion 81, and the outer portion of the corresponding rotational force transmitting member 14d is provided with the transmitting portion 141. In the process in which the process cartridge tray 5 is mounted in the main body 10, the rotational force receiving member 8d and the rotational force transmitting member 14d are gradually approached until the claw portion 81 of the rotational force receiving member 8d and the rotational force transmitting member 14 are provided with the transmitting portion 141. End contact. Since the rotational force transmitting member 14d is fixed in the X direction, as the process cartridge tray 5 is advanced into the main body 10, the rotational force receiving member 8d overcomes the elastic force of the torsion spring 12 toward the opposite oblique direction thereto. The direction is swung until the rotational force receiving member 8d is squared and is coaxial with the rotational force transmitting member 14d, and at this time, the claw portion 81 is engaged with the transmitting portion 141 to transmit power, as shown in FIG.

25 is a schematic structural view showing the non-engagement of the rotational force receiving member and the rotational force transmitting member during the process of withdrawing the process cartridge tray from the main body according to the fifth embodiment, and FIG. 26 is a drawing of the process cartridge tray from the main body provided in the fifth embodiment. The structural diagram of the rotational force receiving member and the rotational force transmitting member are disengaged during the process.

As shown in FIG. 25, when the process cartridge tray is slid in the reverse direction of the X direction (i.e., the -X direction), the rotational force receiving member 8d is detached from the rotational force transmitting member 14d as an example, and the rotational force receiving member 8d is disengaged. The spring force of the torsion spring member 19 is deflected toward the direction of the rotational force transmitting member 14d.

As shown in Fig. 26, it is to be further explained that, after the rotational force receiving member 8d is disengaged from the rotational force transmitting member 14d, as the process cartridge tray 5 slides out in the -X direction, the rotational force receiving member 8d is about to rotate with the rotational force. The end of the transmitting member 14c is in contact, and the pressure in the axial direction of the rotation of the rotational force transmitting member 14c is applied to the rotational force transmitting member 14c while being in contact. Since the elastic force member 17 is provided on the rotational force transmitting member 14c, the rotational force transmitting member 14c can be retracted in the direction of its rotational axis against the elastic force of the elastic member 17, thereby avoiding the movement path of the rotational force receiving member 8d, allowing rotation The force receiving member 8d passes over the rotational force transmitting member 14c. Then, when the box is handled When the disk 5 continues to slide in the -X direction, the rotational force receiving member 8d sequentially retracts the rotational force transmitting members 14b, 14a and passes over them.

Similarly, after the rotational force receiving member 8c is disengaged from the rotational force transmitting member 14c, the rotational force transmitting and transmitting members 14b, 14a are retracted and passed over; similarly, the rotational force receiving member 8b is disengaged from the rotational force transmitting member 14b. Thereafter, the rotational force transmitting and transmitting member 14a is retracted and passed over the rotational force transmitting member 14a; the rotational force receiving member 8a is directly disengaged from the rotational force transmitting member 14a.

In practical applications, in order to further simplify the structure, the end portion of the rotational force transmitting member 14d at the innermost portion of the image forming apparatus may not be provided with the elastic member 17, that is, the rotational force transmitting member 14d may not cause axial movement.

Further, the torsion spring member 19 in the present embodiment can be replaced with another structure which can also cause the rotational force receiving member 8 to swing obliquely. The magnetic member is disposed at a position close to the rotational force receiving member 8 at the end of the process cartridge 20, and the magnetic member is provided on the rotational force receiving member 8, or the rotational force receiving member 8 is provided as a magnet member; thus, the role of the magnetic force Next, the rotational force receiving member 8 can be tilted. It is of course also possible to use a spring to be disposed outside the rotational force receiving member 8, and to force it to tilt in one direction by the elastic force.

FIG. 28 is a schematic view showing the mounting of the process cartridge according to the sixth embodiment of the present invention to the processing cartridge tray. As shown in FIG. 28, the process cartridge 20 is movably inserted into the main body 100, which has the advantage of facilitating the replacement of the process cartridge 20. Specifically, the process cartridge 20 can be mounted on the process cartridge tray 5, and the process cartridge tray 5 can be movably inserted into the main body in the lateral direction (i.e., the Y direction in Fig. 28). A process cartridge tray support is disposed on both side walls of the main body 100 of the image forming apparatus, and the processing cartridge tray support is provided with guide rails for guiding the mounting of the process cartridge tray. The process cartridge tray support comprises a tray upper positioning plate 131 and a tray support bottom plate 132 respectively disposed on two opposite inner walls, wherein the tray upper positioning plate 131 is located above the tray support bottom plate 132. The tray upper positioning plate 131 and the tray support bottom plate 132 play a guiding role in the insertion process of the process cartridge tray 5, and the tray support bottom plate 132 is also used to support the process cartridge tray 5.

A positioning member is further provided in the process cartridge tray 5 to fix the process cartridge 20 in the process cartridge tray 5, and no rattling occurs during operation. When the process cartridge 20 is mounted into the process cartridge tray 5, a portion of the process cartridge tray 5 located inside the main body 100 is supported on the tray support plate 132. A guide rail is disposed on the upper side of the tray support plate 132, and the process cartridge tray 5 is slidable along the rail on the guide rail. A tray positioning plate 131 for guiding the process cartridge tray 5 to move in the horizontal direction, that is, in the Y direction, and also for restricting the longitudinal movement of the process cartridge tray 5. After the process cartridge 20 is mounted on the process cartridge tray 5, the user applies a force in the Y direction to the process cartridge tray 5 to slide the process cartridge tray 5 along the rail into the main body 100, and the process cartridge tray 5 is fully supported. On the tray support plate 132.

The process cartridge tray 5 is provided with four mounting positions for mounting the process cartridge 20, and the process cartridge 20 can be loaded downward into the process cartridge tray 5 in the longitudinal direction (i.e., the X direction in Fig. 28). In order to avoid the rotational force receiving member 8 protruding from the end of the process cartridge 20, it is avoided that the process cartridge tray 5 and the rotational force receiving member 8 interfere with each other during the process cartridge mounting process, and it is required to be on the side wall of each mounting position. The escape groove 51 extending in the longitudinal direction is opened, so that the rotational force receiving member 8 is exposed outside the process cartridge tray 5 to be engaged with the rotational force transmitting member, and the width of the escape groove 51 is larger than the outer size of the rotational force receiving member 8, so as not to The swing of the rotational force receiving member 8 with respect to the rotational axis of the rotating member in the process cartridge is hindered.

The process cartridge tray 5 is mounted with four process cartridges 20 of different colors, and receives the rotational force of the end of the process cartridge 20 The components 8 are numbered 8a, 8b, 8c, and 8d, respectively. Correspondingly, the rotational force transmitting members provided on the main body 100 are also sequentially numbered 14a, 14b, 14c, and 14d. When the image forming apparatus is operated, the rotational force receiving member 8a, 8b, 8c, and 8d are meshed with the rotational force transmitting members 14a, 14b, 14c, and 14d, respectively. In the present embodiment, when the four rotational force receiving members are collectively described, the name of the rotational force receiving member 8 is directly used; and when one of the four rotational force receiving members is separately described, the rotational force is respectively used. The names of the receiving parts 8a, 8b, 8c, 8d are received. A similar description method is also employed for the four rotational force transmitting members.

In addition, a door cover 17 is also provided in the main body 100, and the door cover 17 can be opened or closed with respect to the main body 100. The door cover 17 is specifically hinged to the main body 100.

In the present embodiment, a guide member is provided on the inner wall of the main body 100 for guiding the rotational force receiving member 8 during the insertion process of the process cartridge tray 5, the guide member guiding the rotational force receiving member 8 relative to the process cartridge The deflection is 20, and in turn, meshes with the rotational force transmitting member 14. The guide member is further provided with an inclined surface for contacting the rotational force receiving member 8 during the process of mounting the process cartridge to guide the rotational force receiving member 8 to deflect.

The guide member is provided with a first inclined surface A22 and a second inclined surface A23, respectively. In the process of inserting the process cartridge tray 5 into the main body 100, the first inclined surface A22 is used to guide the rotational force receiving member 8 to be deflected upward, and after the rotational force receiving member 8 is raised and passed the highest limit, the second inclined surface A23 is used to guide the rotation. The force receiving member 8 is deflected downward to be engaged with the rotational force transmitting member. The highest limit is the highest point at which the first inclined surface A22 and the second inclined surface A23 are joined. When the rotational force receiving member 8 comes into contact with the second inclined surface A23, the second inclined surface A23 guides the rotational force receiving member 8 to be deflected such that the rotational axis of the rotational force receiving member 8 occurs with respect to the axis of the rotating member provided in the process cartridge. Tilt, the tilting direction of the rotational force receiving member 8 is inclined toward the direction of the rotational force transmitting member 14 disposed in the main body to be engaged therewith; and one end of the rotational force receiving member 8 is fixed to the end of the process cartridge, and the other end a free end that is angled with an axis of the rotating member in the process cartridge for engaging the rotational force transmitting member to transmit power; at this time, when the rotational force receiving member 8 is guided by the second inclined surface A23 When the deflection occurs, the free end portion of the rotational force receiving member 8 is closer to the rotational force transmitting member 14 provided in the main body 100 than the end portion thereof fixed in the process cartridge 20.

Four guide members are provided on the inner wall of the main body 100, which are sequentially numbered A20a, A20b, A20c, and A20d. When the image forming apparatus is operated, the rotational force receiving members 8a, 8b, 8c, and 8d are meshed with the rotational force transmitting members 14a, 14b, 14c, and 14d by the guiding actions of the guides A20a, A20b, A20c, and A20d, respectively.

Compared with the prior art, the technical solution provided by the embodiment does not need to adopt a complicated control mechanism, but only adopts the relatively simple guiding member as described above, and the rotating force receiving component can be realized after the processing cartridge is inserted into the main body. The rotation force transmitting member is engaged, which simplifies the structure of the image forming apparatus and simplifies the image forming apparatus. The manufacturing process and the mounting process further reduce the cost.

The structure of the above-mentioned guide member and the cooperation relationship with the rotational force receiving member can be realized by a person skilled in the art in various ways. This embodiment provides a specific implementation manner:

The guiding member is a tapered block A20, and the tapered block A20 is provided with a first inclined surface A22 and a second inclined surface A23, wherein the first inclined surface A22 is inclined from the top end of the tapered block A20 toward the outer side of the main body 100, and the second The inclined surface A23 is inclined from the top end of the tapered block A20 toward the inner side of the main body 100.

Fig. 28 shows a state in which a small portion of the process cartridge tray 5 is inserted into the main body 100, but the rotational force receiving member has not been in contact with the guide member. Continuing to advance the process cartridge tray 5 into the main body 100, referring to FIG. 29, FIG. 29 is a view showing the process of mounting the process cartridge tray to which the process cartridge is mounted to the main body according to the sixth embodiment of the present invention, the rotation force receiving member and the taper. Schematic diagram of the action of the first inclined surface of the block.

Fig. 29 shows that the rotational force receiving members 8d and 8c both enter the main body 100 and are in contact with the first inclined surface A22 of the corresponding guide. As shown in FIG. 29, taking the rotational force receiving member 8d as an example, the outer surface of the rotational force receiving member 8d first comes into contact with the first inclined surface A22 of the tapered block A20, and is pushed into the main body 100 as the process cartridge tray 5 is pushed into the main body 100. Since the process cartridge 20 is moved only in the Y direction, the first inclined surface A22 hinders the movement of the rotational force receiving member 8d in the Y direction, and the rotational force receiving member 8d can be opposed to the process cartridge 20 by the action of the universal joint. When the axis of the inner rotating member is deflected, the rotational force receiving member 8d is deflected in the X direction and the -Y direction with respect to the process cartridge 20 by the first inclined surface A22. When the rotational force receiving member 8d passes over the highest point between the first inclined surface A22 and the second inclined surface A23 of the tapered block A20, the rotational force receiving member 8d comes into contact with the second inclined surface A23.

Figure 30 is a structural schematic view showing the action of the rotational force receiving member and the second inclined surface of the tapered block in the process of mounting the process cartridge tray to which the process cartridge is mounted to the main body according to the sixth embodiment of the present invention. As shown in Fig. 30, the outer surface of the rotational force receiving member 8d is in contact with the second inclined surface A23, and the rotational force receiving member 8d is directed toward the X direction with respect to the process cartridge 20 under the action of gravity and the guiding of the second inclined surface A23. The Y direction is inclined such that the free end portion of the rotational force receiving member 8 is in a state of accommodating the rotational force transmitting member 14 in the image forming apparatus, that is, under the guidance of the second inclined surface A23, the free end portion of the rotational force receiving member 8 The free end portion of the rotational force transmitting member is closer to the end to which the process cartridge is coupled, facilitating the engagement of the rotational force receiving member 8 and the rotational force transmitting member 14.

Fig. 31 is a structural schematic view showing the engagement of the rotational force receiving member and the rotational force transmitting member in the process of attaching the process cartridge tray to which the process cartridge is mounted to the main body according to the sixth embodiment of the present invention. When the process cartridge tray 5 is moved to the position shown in Fig. 31, the rotational force receiving member 8d and the rotational force transmitting member 14b are engaged, and the rotational force is coupled. The receiving member 8c is meshed with the rotational force transmitting member 14a, and the rotational force receiving member that meshes with each other is in a state of being coaxial with the rotational force transmitting member.

Figure 32 is a schematic view showing the structure in which the rotation force receiving member and the rotational force transmitting member are disengaged during the process of attaching the process cartridge tray to which the process cartridge is mounted to the main body according to the first embodiment of the present invention. As shown in Fig. 32, the process cartridge tray 5 is continuously pushed in the Y direction, and the rotational force receiving member 8d and the rotational force transmitting member 14b in the engaged state are disengaged from each other, and the rotational force receiving member 8 naturally hangs under the force of gravity.

In summary, during the process in which the process cartridge tray 5 is pushed into the main body 100, the rotational force receiving member 8d is first engaged with the rotational force transmitting member 14a near the entrance of the main body 100 (i.e., near the door cover 17), and with the process cartridge tray When the advancement of 5 is continued, the rotational force receiving member 8d is disengaged from the rotational force transmitting member 14a. Thereafter, the rotational force receiving member 8d is sequentially engaged with the rotational force transmitting members 14b, 14c, and then disengaged; and the rotational force receiving member 8c is sequentially engaged with the rotational force transmitting members 14a, 14b, and then disengaged; the rotational force receiving member 8b will be meshed with the rotational force transmitting member 14a and then disengaged.

Fig. 33 is a structural schematic view showing the mounting of the process cartridge tray to which the process cartridge is mounted in the main body according to the sixth embodiment of the present invention, in which all the rotational force receiving members and the corresponding rotational force transmitting members are engaged. Finally, as shown in Fig. 33, the rotational force receiving members 8a, 8b, 8c, 8d are engaged with the rotational force transmitting members 14a, 14b, 14c, 14d, respectively, and the process cartridge tray 5 is mounted.

With the above technical solution, further, if the tip end of the tapered block A20 is higher than the extreme position of the upward deflection of the rotational force receiving member 8, as shown in Fig. 29, when the rotational force receiving member 8 cannot cross the highest point of the tapered block A20 Then, the tapered block A20 blocks the movement of the process cartridge tray 5. At this time, an elastic member may be provided in the main body 100 for allowing the guide member to move in the longitudinal direction (ie, the X direction). Process cartridge with process cartridge mounting tray During installation, the rotational force receiving member 8 applies a downward force to the tapered block A20, compressing the elastic member, causing the tapered block A20 to move in the X direction (ie, downward Move) so that the rotational force receiving member 8 can smoothly pass over the highest point of the tapered block A0 to reach the second inclined surface A23 of the tapered block A20.

When the rotational force receiving member 8 passes over the highest point of the tapered block A20, the tapered block A20 rebounds to the original position under the elastic force of the elastic member, that is, moves in the -X direction under the elastic force (moves upward).

The elastic member may be a member made of an elastic material or a spring. In this embodiment, a spring A21 is used. One end of the spring A21 is fixed on the main body 100, and the other end is connected to the tapered block A20.

Further, a guide support plate 15 may be disposed in the main body, and the elastic member may be fixed on the guide support plate 15 to enable the elastic member to be compressed between the tapered block A20 and the guide support plate 15. Specifically, one end of the elastic member abuts against the guide support plate 15 and the other end abuts against the guide member.

The process of taking out the process cartridge tray 5 from the main body 100 will be described in detail below:

34a, 34b, 34c, and 34d are views showing the action of the tapered block on the rotational force receiving member in the process of taking out the process cartridge tray according to the sixth embodiment of the present invention. As shown in Fig. 34a, after the rotational force receiving member 8 is disengaged from the rotational force transmitting member 14, the rotational force receiving member 8 and the second inclined surface A23 are in contact, and with the movement of the process cartridge tray 5, the rotational force receiving member 8 Moving along the second inclined surface A23 and deflecting in the -X, Y direction with respect to the process cartridge by the second inclined surface A23, and forcing the tapered block 20 to move in the X direction so that the rotational force receiving member 8 passes over the taper The highest point of block A20. After the rotational force receiving member 8 passes over the highest point of the tapered block A20, as shown in Fig. 34b, the surface of the rotational force receiving member 8 comes into contact with the first inclined surface A22 of the tapered block A20, and with the process cartridge tray 5 The extraction is out of contact with the tapered block A20, as shown in Fig. 34c, and under the action of gravity, the rotational force receiving member 8 naturally hangs so that the rotational force is received when passing the adjacent rotational force transmitting member 14. The free end of the member 8 is below the adjacent rotational force transmitting member 14.

In summary, during the movement of the process cartridge tray 5 in the -Y direction, the rotational force receiving member 8d comes into contact with and comes into contact with the tapered block A20d, contacts and disengages with the tapered block A20c, and contacts the tapered block A20b. Disengagement, contact with and contact with the tapered block A20a. The rotational force receiving member 8c is in contact with and out of contact with the tapered block A20c, contact and disengagement with the tapered block A20b, and contact and disengagement with the tapered block A20a. The rotational force receiving member 8b is in contact with and out of contact with the tapered block A20b in turn, in contact with and out of contact with the tapered block A20a. The rotating force receiving member 8a is in contact with and out of contact with the tapered block A20a. The process of contact and disengagement can be referred to Figures 34a to 34c.

In the above process, the rotational force receiving member 8 applies a downward pressure to the tapered block A20 from the second inclined surface A23 over the highest point of the tapered block A20, causing the spring A21 to compress. Further, in order to restrict the movement of the guide member to move in the X direction, in the embodiment, a guide rail disposed in the longitudinal direction is further provided in the main body 100, and the guide member guide rail is used for guiding the guide member. Move in the longitudinal direction and restrict the guide from moving in the lateral direction.

Further, as shown in FIG. 34d, when the process cartridge tray 5 is mounted to the main body 100, in order to ensure that the rotational force receiving member 8 and the rotational force transmitting member 14 can be properly engaged after the process cartridge tray 5 is mounted in the main body 100, The shortest distance L1 between the rotational force transmitting member 14 and the second inclined surface A23 is smaller than the distance L3 between the contact point of the rotational force transmitting member 14 and the rotational force receiving member 8 and the second inclined surface A23.

However, in the process of pulling out the process cartridge tray 5, since L3>L1, the rotational force receiving member 8 is caught between the rotational force transmitting member 14 and the second inclined surface A23 of the tapered block A20, hindering the process cartridge tray 5 The movement. In the present embodiment, by providing the elastic member between the tapered block A20 and the main body 100, the rotational force receiving member 8 can push the tapered block A20 downward by a distance in the X direction, so that the rotational force receiving member 8 can smoothly pass from The rotational force transmitting member 14 and the second inclined surface A23 of the tapered block A20 are disengaged and further moved along the second inclined surface A23. The use of the elastic member ensures that the rotation force receiving member 8 can smoothly mesh with the rotational force transmitting member 14 when the process cartridge tray 5 is mounted in the main body 100, and at the same time, when the process cartridge tray 5 is pulled out, the rotational force transmitting member 14 is prevented from being opposed. The rotational force receiving member 8 causes interference.

The detailed process of the rotation force receiving member 8 avoiding the interference of the rotational force transmitting member 14 and the second inclined surface A23 during the process of taking out the process cartridge tray 5 from the main body 100 in the present embodiment will be described below.

When the rotational force receiving member 8 is moved to the position shown in FIG. 34d, since the gap between the rotational force transmitting member 14 and the second inclined surface A23 of the tapered block A20 is L1, less than the rotational force transmitting member 14 and the rotational force receiving The distance L3 between the contact point of the member 8 and the second inclined surface A23, therefore, the rotational force receiving member 8 is interfered. Continuing to move the process cartridge tray 5 in the -Y direction, the rotational force receiving member 8 applies a downward thrust to the second inclined surface A23, and since the elastic member A21 is provided on the main body 100, the force is applied by the rotational force receiving member 8 The block A20 moves in the vertical direction (the direction of X) by one end distance, and when the taper block A20 moves from the dotted line position in Fig. 34d to the solid line position, that is, when moving to the lowest position, the moving distance is H, and the rotation The shortest distance between the force transmitting member 14 and the second inclined surface A23 becomes L2, and L2 ≥ L3 is satisfied, so that the rotational force receiving member 8 passes, and the process cartridge tray 5 is smoothly taken out.

FIG. 35 is a schematic structural diagram of an image forming apparatus according to Embodiment 6 of the present invention. In practical applications, in order to further simplify the structure, a plurality of tapered blocks A20 may be integrated to form one plate, that is, all on one guiding member, as shown in FIG. 35, the guiding member is a guiding plate B25, and the guiding plate B25 Four first inclined faces B22 and four second inclined faces B23 are provided. Specifically, the guide plate 25 is provided with a plurality of protrusions at one end in the -X direction, and the two sides of the protrusion are respectively the first inclined surface B22 and the second inclined surface B23, and the inclination angle and the position of each inclined surface can be referred to The above embodiment.

In addition, an elastic member may be disposed between the guide plate 25 and the support plate 15 so that the guide plate B25 can be freely moved in the X direction in the main body 100, and the guide plate B25 can be retracted by a certain distance to facilitate the processing of the rotational force on the casing. Engagement and disengagement between the receiving member and the rotational force transmitting member within the body.

Example 7

Unlike the above embodiment, the present embodiment employs a guide member of another structure, so that the process cartridge tray 5 can be smoothly mounted into and taken out from the main body 100.

Figure 36 is a schematic diagram showing the structure of an image forming apparatus according to a seventh embodiment of the present invention. As shown in Figure 36, the above The guiding member may also be a curved rod C30. The curved rod C30 includes a first inclined rod C31 and a second inclined rod C32. The first inclined rod C31 and the second inclined rod C32 are connected to each other, and the two are set at an angle. The angle can be an acute angle, a right angle or an obtuse angle. The first inclined rod C31 and the second inclined rod C32 are connected to each other as the highest point of the guide member. The first inclined rod 31 extends from the highest point toward the outside of the main body 100, and the rotational force receiving member 8 is in contact with the first inclined rod C31. The surface is the first inclined surface; the second inclined rod C32 extends from the highest point toward the inner side of the main body 100, and the surface of the rotational force receiving member 8 in contact with the second inclined rod C32 serves as the second inclined surface. Preferably, the first inclined rod C31 and the second inclined rod C32 are connected by an arc.

Still taking an image forming apparatus provided with four process cartridges as an example, the number of the curved bars C30 is four, and is arranged side by side in the main body 100. In the process of inserting the process cartridge tray 5 into the main body 100, taking the rotational force receiving member 8d as an example, the rotational force receiving member 8d first comes into contact with the first inclined rod C31 in the outermost curved rod C30, when the highest of the curved rod C30 is crossed. After the point, the rotational force receiving member 8d comes into contact with the second tilting lever C32 and is deflected downward by the second inclined surface. At this time, the free end portion of the rotational force receiving member 8d faces the inside of the main body 100 and caters to the rotational force. The member 14a is transferred until it engages with the rotational force transmitting member 14a. As the process cartridge tray 5 is further moved into the main body 100, the rotational force receiving member 8d is disengaged from the rotational force transmitting member 14a, and then sequentially contacts the rear three curved levers C30, and functions in each of the curved levers C30. The lower portion is deflected with respect to the axis of the rotating member in the process cartridge 20 until it engages with the rotational force transmitting member 14d. For the other rotational force receiving members 8a, 8b, and 8c, the state change process can be referred to the above embodiment.

Compared with the prior art, the technical solution provided by the embodiment also does not need to adopt a complicated control mechanism, and only adopts the curved rod as described above as a guiding member, and the structure thereof is very simple, and can be realized after the processing box is inserted into the main body. The rotational force receiving member is engaged with the rotational force transmitting member, which simplifies the structure of the image forming apparatus, simplifies the manufacturing process and the mounting process of the image forming apparatus, and further reduces the cost.

Further, in order to facilitate the smoothing of the rotational force receiving member 8 over the highest point of the curved rod C30, the end of one end of the curved rod C30 can be hinged to the main body 100 such that the curved rod C30 can be parallel to the plane formed by the intersection of X and Y. Rotate in the plane. Specifically, one end of the first tilting lever C31 may be hinged to the main body 100, or one end of the second tilting lever C32 may be hinged to the main body 100. FIG. 36 shows that one end of the second tilting lever C32 is hinged to the main body 100.

Specifically, a guide support plate C15 for supporting the guide member may be disposed in the main body 100, and a hinge fixing portion C36 is disposed on the guide support plate C15, and one end of the second inclined rod C32 is hinged to the hinge fixing portion C6. At point C33, the curved rod C30 is free to rotate about its hinge point C33. A plurality of stoppers C37 are disposed in the main body 100, and the stopper C37 is located above the second tilting rod C32 of the curved rod C30 for limiting the second inclined rod C32. The angle of rotation. The highest point of the stopper C37 in the X direction needs to be lower than the lowest point at which the rotational force receiving member 8 is in contact with the curved rod C30, preventing the stopper C37 when the process cartridge 20 is attached to or pulled out from the main body 100. The rotation force receiving member 8 is caused to interfere.

Further, an elastic member is further disposed between the second inclined rod C32 and the guide supporting plate 15. In this embodiment, the elastic member is preferably a torsion spring C34. The spring portion of the torsion spring C34 is disposed on a rotating shaft C38 fixed to the side wall of the main body 100. The first elastic end of the torsion spring C34 abuts against the main body. The guide support plate 15 of 100 has the other end abutting against the lower surface C32b of the second tilting lever C32 of the curved lever C30, and applies an elastic force to the second tilting lever C32 so that the second upper surface of the second tilting lever C32 C32a is in contact with the stopper C7, and the position of the curved rod C30 is determined.

37a, 37b, 37c, and 37d are diagrams showing the meshing process of the rotational force receiving member and the rotational force transmitting member in the process of installing the process cartridge tray into the main body according to the seventh embodiment of the present invention. As shown in Figs. 37a and 37b, since the rotational force receiving member 8 and the photosensitive member 9 are joint joints, when the rotational force receiving member 8 is only subjected to gravity, the rotational force receiving member 8 is in a natural drooping state. In order to ensure that the rotational force receiving member 8 and the first tilting lever C31 are in contact, the rotational force receiving member 8 can be in contact with the first upper surface C31a of the first tilting lever C31, and the hanging end point C35 of the first tilting lever C31 is in the X direction. The highest point is located below the rotational force receiving member 8 in the natural drooping state. The process cartridge tray 5 is moved in the Y direction, and the rotational force receiving member 8 is first brought into contact with the first upper surface C31a of the first tilt lever C31 of the curved lever C30 while the rotational force receiving member 8 moves with the process cartridge tray 5. Moving along the first upper surface C31a of the first tilting lever C31.

As shown in Figs. 37c, 37d, the process cartridge tray 5 is continuously pushed, and the rotational force receiving member 8 passes over the highest point of the curved rod C30, comes into contact with the second upper surface C32a of the second inclined rod C32, and is in the second inclined rod. The C32 is deflected by a certain angle in the Y direction and the X direction to facilitate the meshing between the rotational force receiving member 8 and the rotational force transmitting member 14.

Since the process cartridge can only move in the Y direction and cannot move in the X direction, if the highest point of the connection portion between the first tilt lever C31 and the second tilt lever C32 is too high, the rotational force receiving member 8 cannot pass the highest point. . In the configuration of the present embodiment, the torsion spring C34 is disposed below the curved rod C30, and when the rotational force receiving member 8 approaches the highest point of the curved rod C30, the rotational force receiving member 8 applies a downward force to the curved rod C30. Under the action of the force, the curved rod C30 will rotate counterclockwise around the hinge point C33, so that the highest point of the curved rod C30 is lowered, and the rotational force receiving member 8 can smoothly pass the highest point. After the rotational force receiving member 8 passes the highest point, under the elastic force of the torsion spring C34, the curved rod C30 is rotated clockwise back to the initial position so as not to affect the engagement of the rotational force receiving member 8 and the rotational force transmitting member 14.

38a, 38b, 38c, and 38d are views showing the action of the curved lever on the rotational force receiving member in the process of taking out the process cartridge tray according to the seventh embodiment of the present invention. Referring to Figures 38a to 38d, the action of the rotational force transmitting member 14 and the curved lever C30 on the rotational force receiving member 8 when the process cartridge tray 5 is taken out from the main body 100 will be described.

As shown in Fig. 38a, when the process cartridge tray 5 is started to be pulled in the -Y direction, the rotational force receiving member 8 and the rotational force transmitting member 14 in the engaged state are disengaged, and under the action of gravity, the rotational force receiving member 8 and the curved The second tilting lever C32 of the lever C30 is in contact, and slides along the -Y direction on the second upper surface C32a of the second tilting lever C32 as the process cartridge tray 5 moves. Continuing to move the process cartridge tray 5, the rotational force receiving member 8 applies a force to the second tilting lever C32 of the curved lever C30. Under the action of the force, the curved lever C30 rotates counterclockwise around the hinge point C33. The angle lowers the highest point of the curved rod C30, facilitating the rotation force receiving member 8 to pass the highest point of the curved rod C30.

As shown in Fig. 38b, the rotational force receiving member 8 is in contact with the first upper surface C31a of the first tilting lever C31 of the curved lever C30 over the highest point of the curved lever C30, and at the first upper surface C31a of the first tilting lever C31. Slide in the -Y direction.

Finally, as shown in Fig. 38c, the rotational force receiving member 8 is disengaged from the contact with the curved rod C30, and is in a state of natural drooping.

The detailed process of the rotational force receiving member 8 avoiding the interference of the rotational force transmitting member 14 and the second tilting lever C32 during the process of taking out the process cartridge tray 5 from the main body 100 will be described in detail below.

As shown in Fig. 38d, when the rotational force receiving member 8 is moved to the position shown in Fig. 38d, the rotational force receiving member comes into contact with the second upper surface C32a of the second tilting lever C32 and the rotational force transmitting member 14.

In order to ensure that the rotational force receiving member 8 and the rotational force transmitting member 14 can be properly engaged after the process cartridge tray 5 is mounted in the main body 100, the shortest distance L1 between the rotational force transmitting member 14 and the second inclined surface C23 is smaller than the rotational force. The distance L3 between the contact point of the transmitting member 14 and the rotational force receiving member 8 and the second inclined surface C23.

However, in the process of taking out the process cartridge tray 5 from the main body 100, when the rotational force receiving member 8 is moved to the position shown in Fig. 37d, since L1 < L3, the rotational force receiving member 8 cannot pass the rotational force transmitting member. The gap between the 14 and the second tilt lever C32 causes the process cartridge tray 5 to be unsuccessfully taken out. When the process cartridge tray 5 is continuously moved, the rotational force transmitting member 14 applies a resistance to the rotational force receiving member 8, and since the rotational force receiving member 8 and the process cartridge 20 are connected to the cardan shaft, the rotation axis of the photosensitive member 9 can be bypassed. Swing in any direction, therefore, the rotational force receiving member 8 transmits the received resistance to the second inclination of the curved rod C30 On the rod C32, a torsion spring C34 is disposed between the second inclined rod C32 of the curved rod C30 and the guide supporting plate 15 in the main body 100, and the curved rod C30 can be rotated about the hinge point C33, when the curved rod C30 is rotated After the force transmitted by the force receiving member 8, the curved rod C30 is rotated about the hinge point C33 from the position of the broken line in FIG. 38d to the -Y direction, and when rotated to the maximum angle, the rotational force transmitting member 14 and the second inclined The shortest distance between the second upper surface C32a of the rod C32 becomes L2, and L2 ≥ L3 is satisfied, so that the rotational force receiving member 8 passes smoothly, and the force of the rotational force receiving member 8 against the second tilting rod C32 also disappears. Under the action of the torsion spring C34, the curved lever 30 will return to the position of the broken line shown in Fig. 38d.

39 is a schematic structural diagram of another image forming apparatus according to Embodiment 7 of the present invention, and FIGS. 40a and 40b are schematic structural views of another curved lever according to Embodiment 7 of the present invention. Of course, as shown in FIG. 39, FIG. 40a, and FIG. 40b, those skilled in the art can easily think of the reverse of the curved bar and the torsion spring according to the content of the embodiment, that is, the first in the curved bar D30. A tilting lever D31 is hinged on the main body 100, and its hinge point is also referred to as a hinge point D33. The crank lever D30 can be rotated about the hinge point D33, and the same purpose can be achieved.

Alternatively, a linear spring may be disposed between the curved rod D30 and the main body 100 so that the curved rod D30 can move in the X direction, and the same purpose can be achieved as well. Alternatively, those skilled in the art may use other methods to implement the functions of the above-mentioned guiding members, which is not limited in this embodiment.

Example eight

This embodiment provides a guide member of another structure, so that the process cartridge tray 5 can be smoothly mounted into and taken out from the main body 100.

Figure 41 is a schematic diagram showing the structure of an image forming apparatus according to Embodiment 8 of the present invention. As shown in FIG. 41, the guiding member may further be a guiding plate E40 provided with a plurality of protrusions E41 arranged side by side. The protrusions E41 are disposed above the guiding plate E40, and the inclined ends are disposed on both sides of the top end of each of the protrusions E41. The first inclined surface E22 and the second inclined surface E23 are opposite. Among them, the first inclined surface E22 is inclined from the distal end of the projection E41 toward the outer side of the main body 100, and the second inclined surface E23 is inclined from the distal end of the projection E41 toward the inner side of the main body 100. The position where the first inclined surface E22 and the second inclined surface E23 are connected is the highest point of the entire guide plate E40, that is, the top end of the above-mentioned projection E41. The top end of the protrusion E41 may be a tip end, or may be a flat surface or a curved surface having a gentle slope.

42a, 42b, 42c, and 42d are diagrams showing the meshing process of the rotational force receiving member and the rotational force transmitting member in the process of installing the process cartridge tray into the main body according to the eighth embodiment of the present invention. Still taking an image forming apparatus provided with four process cartridges as an example, the number of the projections E41 provided on the guide plate E40 is four. In the process of inserting the process cartridge tray 5 into the main body 100, taking the rotational force receiving member 8d as an example, the rotational force receiving member 8d first comes into contact with the first inclined surface E22 of the outermost projection E41 when crossing the top end of the projection E41. After that, the rotational force receiving part 8d In contact with the second inclined surface E23 and downwardly deflected by the second inclined surface E23, the free end portion of the rotational force receiving member 8d faces and greets the free end portion of the rotational force transmitting member 14a until the rotational force receiving member 14a is engaged. As the process cartridge tray 5 moves further into the main body 100, the rotational force receiving member 8d and the rotational force transmitting member 14a are disengaged.

Unlike the above embodiment, in the process of the rotational force receiving member 8d being disengaged from the rotational force transmitting member 14a, the rotational force receiving member 8d is directed toward the process cartridge with respect to the process cartridge 20 as the process cartridge tray is further mounted. The tray 5 is swayed in the opposite direction of the mounting direction, and is further disengaged from the rotational force transmitting member 14a, and is in contact with the first inclined surface E22 of the protrusion E41 adjacent to the inside of the rotational force transmitting member 14a, and then passes over the top end of the adjacent projection E41. And under the action of the second inclined surface E23 of the adjacent projection E41, the free end portion of the rotational force receiving member 8d faces and greets the free end portion of the rotational force transmitting member 14b, with further installation of the process cartridge tray 5, The rotational force receiving member 14a is meshed with the rotational force transmitting member 14b. Similarly, for the other rotational force receiving members 8a, 8b, and 8c, the process of engaging and disengaging is the same as the above process.

Further, in order to facilitate the smooth engagement of the rotational force receiving member 8 with the rotational force transmitting member 14, it is necessary to limit the height of the tip end of the projection E41, that is, the highest point of the projection E41 is lower than that of the rotational force receiving member 8 in the longitudinal direction. When the upward (i.e., -X direction) is swung to the extreme position, the rotational force receiving member 8 is at the lowest point on the plane of the guide plate E40 so that the tip end of the projection E41 does not interfere with the normal movement of the rotational force receiving member 8.

43a, 43b, and 43c are diagrams showing the meshing process of the rotational force receiving member and the rotational force transmitting member in the process of taking out the process cartridge tray from the main body according to the eighth embodiment of the present invention. Referring to Figs. 43a to 43c, taking 8d as an example, the action of the rotational force transmitting member 14 and the guide plate E40 on the rotational force receiving member 8 when the process cartridge tray 5 is taken out from the main body 100 will be described in detail.

As shown in Fig. 43a, when the process cartridge tray 5 is started to be pulled in the -Y direction, the rotational force receiving member 8d and the rotational force transmitting member 14d in the engaged state are disengaged, and the rotational force receiving member 8d and the rotational force transmitting member 14d are Before being completely disengaged, the rotational force receiving member 8d first comes into contact with the second inclined surface E23 outside the rotational force transmitting member 14d, and on the second inclined surface E23 along the -Y direction as the process cartridge tray 5 moves slide. Then, the rotational force receiving member 8d passes over the tip end of the projection E41, and comes into contact with the first inclined surface E22 adjacent to the outer side of the second inclined surface E23, and follows the movement in the -Y direction as the process cartridge tray 5 moves. Slide on an inclined surface E22. The rotational force receiving member 8d is meshed with the rotational force transmitting member 14c on the outer side thereof under the guidance of the first inclined surface E22. In this way, it is possible to prevent the rotational force transmitting member 14 from interfering with the rotational force receiving member 8, thereby hindering the process cartridge tray 5 from being taken out from the main body.

In order to ensure that the rotational force receiving member 8 and the rotational force transmission are transmitted after the process cartridge tray 5 is mounted in the main body 100 The hand member 14 can be properly engaged, and the shortest distance L1 between the rotational force transmitting member 14 and the second inclined surface E23 is smaller than the distance between the contact point of the rotational force transmitting member 14 and the rotational force receiving member 8 and the second inclined surface E23. L3. At the same time, in order to take out the process cartridge tray 5 from the main body, the rotational force receiving member 8 can smoothly engage the smooth rotational force transmitting member 14, and the rotational force transmitting member 14 and the first inclined surface E22 are The shortest distance L4 is smaller than the distance L5 between the contact point of the rotational force transmitting member 14 and the rotational force receiving member 8 and the first inclined surface E22.

Therefore, in the process of taking out the process cartridge tray 5 from the main body, the rotational force receiving member 8 is engaged with and disengaged from the rotational force transmitting member 14 on the outer side thereof, effectively avoiding the rotational force transmitting member 14 to the rotational force receiving member 8 The interference is made so that the process cartridge tray 5 can be taken out smoothly.

Of course, those skilled in the art can easily think of replacing the guide plate with a rod-shaped structure, such as the long rod F50 shown in FIG. 44, in which the long rod F50 is provided with four according to the content of the embodiment. The first inclined surface F22 and the four second inclined surfaces F23 each have a top end between the first inclined surface F22 and the second inclined surface F23.
