Detailed Description

The present invention will be explained with reference to the drawings and examples, which are only for explaining the present invention and are not to be construed as limiting the present invention.

In this application, the power receiving member is fixedly mounted to the side of the process cartridge and is engageable with the power applying member to transmit power to the photosensitive drum or the developing roller on the process cartridge.

Example :

as shown in FIG. 1, a process of mounting a process cartridge to a main body 1 (also called a main body) of an image forming apparatus, as shown in FIG. 1, a process cartridge 2 includes a power receiving member 20 (also called a power receiving head) provided on a side of a process cartridge , a developing member 21 provided inside the process cartridge, a left side 22 and a right side 23. the power receiving member 20 transmits a received driving force to the developing member 21 and other members on the process cartridge through a power transmitting member 200, and these members rotate.A main body 1 of the image forming apparatus (also called an image forming apparatus) includes a power applying member 10 (also called a main body driving shaft), a photosensitive member 11 (also called a photosensitive drum) provided inside the main body 1, and the power applying member 10 is provided on a side of the main body 1.

As shown in fig. 2, the power receiving member 20 and the power transmitting member 200 are connected by a cross coupling 03 (also called a cross coupling mechanism or a planar moving mechanism) so that the power receiving member 20 can move freely relative to the power transmitting member 200 in a plane perpendicular to the axis of the power transmitting member 200 and can transmit power when the power receiving member 20 is not coaxial with the power transmitting member 200. The cross-coupling 03 comprises a head 031, a channel member 032 and a base 033.

As shown in FIG. 3, since the power receiving member 20 can move freely in a plane relative to the power transmitting member 200, in order to ensure that the axis X2 of the power receiving member 20 coincides with the axis X3 of the power transmitting member 200 without receiving an external force, a peripheral elastic member 201 is provided, as shown in FIG. 3, a schematic diagram of kinds of peripheral elastic members 201 is shown, as shown in FIG. 3, the peripheral elastic member 201 is in a tapered shape, the end with a small diameter is connected with the power receiving member 20, and the end with a large diameter is connected with the right side 23 of the process cartridge 1, and after such a peripheral elastic member 201 is provided, the axis X2 of the power receiving member 20 can be ensured to coincide with the axis X3 of the power transmitting member 200 without an external force, as shown in FIG. 4, the power receiving member 20 can move in a plane relative to the power transmitting member 200, and during the movement, the axis X2 thereof is always kept parallel to the axis X3 of the power receiving member 200.

As shown in fig. 5 and 6, since the cross-coupling 03 is provided between the power receiving member 20 and the power transmitting member 200, when the process cartridge is attached to or detached from the main unit, the power receiving member 20 can move on a plane perpendicular to the axial direction thereof when interference is generated between the power receiving member 20 and the power applying member 10 because the power receiving member 20 and the power applying member 10 overlap by the amount M in the axial direction.

Fig. 7 shows another alternative of the peripheral elastic member, which is configured in such a manner that a spring a 202 and a spring B203 are symmetrically provided at both ends of the power receiving member 20, and the spring a 202 and the spring B203 are respectively located upstream and downstream in the cartridge mounting direction, and when the power receiving member 20 is moved in the upstream and downstream directions of the cartridge mounting direction perpendicular to the axis thereof, the spring a and the spring B can provide elastic restoring force thereto, so that the power receiving member 20 can be finally restored to a position where the axial direction thereof coincides with the axis of the power transmitting member 200.

Fig. 8 is a schematic view showing a structure of a non-driving end ( end far from a power receiving member) of the process cartridge, from which it can be seen that a left swing link 221, a left elastic member 222, and a left recess 223 accommodating the left swing link 221 and the left elastic member 222 are provided on the left side 22 of the process cartridge, as shown in the drawing, the left swing link 221 is swingable within the left recess 223, the end of the left elastic member 222 abuts against the left swing link 221, the end abuts against the side within the left recess 223 and provides an elastic restoring force for the left swing link 221, and a distance between the left swing link 221 and the developing member 21 is L1.

As shown in FIG. 9, the driving end ( end where the power receiving element is located) of the process cartridge is schematically shown, and it can be seen that the right side 23 of the process cartridge is provided with a right swing link 231, a right elastic element 232, and a right groove 233 for accommodating the right swing link 231 and the right elastic element 232. As shown in the figure, the right swing link 231 can swing in the right groove 233, the end of the right elastic element 232 abuts against the right swing link 231, the end abuts against the side in the right groove 233 and provides elastic restoring force for the right swing link 231. the distance between the right swing link 231 and the developing element 21 is L2. and L2 is greater than L1, i.e., the distance from the right swing link 231 to a certain element on the process cartridge is greater than the distance from the left swing link 221 to the element.

As shown in fig. 8 and 9, the main body is further provided with a left slider 12 and a right slider 13, the left slider 12 is provided with a left slider groove 121, and the right slider 13 is provided with a right slider groove 131. in an initial state, when the process cartridge is mounted to the main body, the developing element 21 on the left side 22 and the developing element 21 on the right side 23 both abut against the photosensitive element 11 (or the distance from the developing element 21 on the left side and the distance from the developing element 21 on the right side to the photosensitive element 11 on the main body are the same), and the distance from the left slider 12 and the right slider 13 on the main body to the photosensitive element 11 on the main body (which may be any elements on the main body) is the same, and the distance from the left slider groove 121 and the right slider groove 131 to the photosensitive element 11 on the main body (which may be any elements on the main.

As shown in fig. 8 and 9, when the process cartridge is in the initial state, the left swing link 221 is close to the side of the left slider groove 121 close to the developing element, and the right swing link 231 is away from the side of the right slider groove 131 close to the developing element.

Fig. 10 is a plan view of the process cartridge shown in fig. 8 and 9 in an initial position. When the process cartridge is mounted to the main body in the direction of the arrow shown in the figure, the axis of the developing member 21 is parallel to the axis of the photosensitive member 11 (i.e., the developing member 21 on the left side and the developing member 21 on the right side are the same distance from the photosensitive member 11), the process cartridge is in the initial state. As can be seen, the process cartridge 1 has a left side 22 and a right side 23. The left side 22 is provided with a left swing link 221 and a left groove 223, and the main machine is correspondingly provided with a left slider groove 121. The right side 23 is provided with a right swing rod 231 and a right groove 233, and the main machine is correspondingly provided with a right slider groove 131. As can be seen, the distance from the left swing link 221 to the developing unit 21 is smaller than the distance from the right swing link 231 to the developing unit 21. And the left and

right slider grooves

121 and 131 on the main body have the same distance to the photosensitive element 11. When the process cartridge is mounted to the main body, the axis X2 of the power receiving member 20 is parallel to but not coincident with the axis X1 of the power applying member 10.

Fig. 11 is a plan view of the process cartridge shown in fig. 8 and 9 in another states at the initial position, which is a schematic view of the state when the power receiving member 20 on the process cartridge is engaged with the power applying member 10 on the main body and transmits power, and unlike fig. 10, the developing member 21 abuts against the photosensitive member 11 and the axis X2 of the power receiving member 20 coincides with the axis X1 of the power applying member 10.

As shown in fig. 12 and 13, the left slider 12 and the right slider 13 are moved away from the photosensitive element 11 in the direction of the arrow shown in the drawing, and then the left side 22 and the right side 23 on the process cartridge are illustrated, and as can be seen from fig. 12, when the left slider 12 is moved away from the photosensitive element 11 in the direction of the arrow shown in the drawing (as can be seen from the drawing, the side on the left slider groove 121 close to the developing element is abutted to the left rocker 221), and therefore, when the left slider 12 is moved, the left side 22 of the process cartridge is moved, so that the distance between the developing element 21 on the left side and the photosensitive element 11 is changed from the abutting state shown in fig. 8 to a state separated by a distance N1 of , the left slider 12 is moved away from the photosensitive element 11, as can be seen from fig. 13, when the right slider 13 is moved away from the photosensitive element 11 in the direction of the arrow shown in the drawing (the same distance as the distance moved by the left slider is moved less than or equal to the width of the left slider groove 121), the right slider is moved to the developing element 21 close to the developing element 3521 on the right slider 21, that the developing element 21 is still close to the developing element 21 on the developing element 21, i.e. the developing element 3521, and the developing element 21 is still close to the developing element 21 on the developing element 21 shown in the developing element 3521 shown.

Fig. 14 is a plan view showing the process cartridge in the state shown in fig. 12 and 13. As can be seen, an angle is formed between the axis of the developing element 21 and the axis of the photosensitive element 11 (i.e. not parallel), the left side of the developing element 21 is far away from the photosensitive element 11, while the right side is still in contact with the photosensitive element 11, and an angle is also formed between the axis X2 of the power receiving element and the axis X1 of the power applying element. The state of the process cartridge on the host computer changes from fig. 10 to the state shown in fig. 14. At this time, the amount of overlap M between the power receiving element 20 and the power applying element 10 becomes small or zero.

Fig. 15 is a plan view showing the process cartridge in another states shown in fig. 12 and 13, where the state of the process cartridge on the main body is changed from fig. 11 to the state shown in fig. 15, it can be seen that an angle is formed between the axis of the developing member 21 and the axis of the photosensitive member 11 (i.e., not parallel), the left side of the developing member 21 is away from the photosensitive member 11, while the right side is still in abutment with the photosensitive member 11, and an angle is also formed between the axis X2 of the power receiving member and the axis X1 of the power applying member, although the power receiving member 20 is still engaged with the power applying member 10 at this time, the process cartridge can be carried away from the photosensitive member 11 by the left slider 12 and the right slider 13 by the spider 03, and the amount M of overlap between the power receiving member 20 and the power applying member 10 becomes small or zero at this time due to the inclination of the process cartridge, so that the power receiving member 20 is more easily disengaged from the power applying.

As can be seen from fig. 16 and 17, when the left slider 12 and the right slider 13 continue to move in the direction of the arrow, the left swing link 221 is pulled by the left slider groove 121 to continue to move in the direction of the arrow, so that the distance N1 from the left developing element 21 to the photosensitive element 11 is further increased by steps, and the right swing link 231 is pulled by the right slider groove 131 to move in the direction of the arrow, at which time the right developing element 21 and the photosensitive element no longer abut against each other, but are pulled by by a distance N2, and N1 is greater than N2.

Fig. 18 is a plan view of the process cartridge in the state shown in fig. 16 and 17, and the state of the process cartridge on the main unit is changed from fig. 14 to the state shown in fig. 18, at which time the developing member 21 is further stepped away from the photosensitive member 11, and the power receiving member 20 is returned to the coaxial state with the power transmitting member 200 by the peripheral elastic member 201.

Fig. 19 is a plan view of the process cartridge in another states shown in fig. 16 and 17, the state of the process cartridge on the main body is changed from fig. 15 to the state shown in fig. 19, at which time the developing member 21 is further stepped away from the photosensitive member 11, and the power receiving member 20 is disengaged from the power applying member and is returned to the coaxial state with the power transmitting member 200 by the peripheral elastic member 201.

When the left slider 12 and the right slider 13 of the main body are moved in the direction opposite to the arrow direction in fig. 16 and 17, the sides of the left slider groove 121 and the right slider groove 131 away from the developing unit 21 abut against the left side swing link 221 and the right side swing link 231, respectively, and push the left side swing link 221 and the right side swing link 231 to move in the direction approaching the photosensitive unit 11, the left side swing link 221 and the right side swing link 231 push the left side 22 and the right side 23 of the process cartridge to move in the direction approaching the photosensitive unit 11, respectively, by the left side elastic member 222 and the right side elastic member 232, so that the process cartridge as a whole moves in the direction approaching the photosensitive unit 11, at this time, the process cartridge is moved from the state shown in fig. 18 to the state shown in fig. 14, the amount of overlap M between the power receiving unit 20 and the power applying unit 10 is small or zero, and.

Example two:

fig. 20-23 illustrate a second embodiment.

As shown in fig. 20, the main body 1 is provided with a power applying member 10, and the process cartridge 2 is provided with a power receiving member 20, a left side 22, a right side 23, and a sloping block 25 adjacent to the power receiving member 20, a push block 25a and an elastic member 25b provided at an end distant from the power receiving member 20 .

As can be seen from the drawing, the swash block 25 is provided on the side of the power receiving member 20 and in close proximity to the power receiving member 20, is provided with a slope, and is located downstream of the power receiving member 20 in the mounting direction of the process cartridge, and the height of the swash block 25 in the axial direction of the power receiving member is greater than or equal to the height of the power receiving member 20 (i.e., the swash block 25 protrudes farther or the same distance as the power receiving member 20 in the axial direction). a push block 25a is provided on the side of the process cartridge away from the power receiving member 20, and the push block 25a is located in the projection range of the swash block 25 in the axial direction.

As shown in fig. 20, when the process cartridge is mounted to the main body, the power receiving member 20 and the power applying member 10 have a coincidence amount M in the axial direction. When the process cartridge is mounted to the main body in the direction of the arrow shown in the drawing, since the swash block 25 protrudes farther or the same distance in the axial direction than the power receiving member 20 and the swash block 25 is disposed downstream in the mounting direction of the process cartridge, the swash block 25 is in contact with the power applying member 10 when the process cartridge is mounted to the main body, as shown in fig. 21.

When the process cartridge is further pushed in the direction of the arrow shown in the figure, since the inclined surface is present on the inclined block 25, the power applying member 10 engages with the inclined surface to move the process cartridge to the left side in the axial direction (as shown by the arrow in fig. 22), at which time the pushing block 25a retracts inside the process cartridge, and the elastic member 25b is compressed.

When the power applying member 10 is disengaged from the ramp 25, the process cartridge is moved rightward by the elastic member 25b and the push block 25a, and since the ramp 25 abuts against the power receiving member 20, the process cartridge can be engaged with the power receiving member 20 when the power applying member 10 is disengaged from the ramp 25.

Example three:

as shown in fig. 24-39, which is a third embodiment, as shown in fig. 24 and 25, a power applying member 09 is provided on the main body 1, a power receiving head 04 (i.e., a power receiving member), a drum gear 01 and an end cover plate 05 are provided on the process cartridge 2, the amount of overlap between the power receiving member 20 and the power applying member 10 in the axial direction of the power receiving member 20 is m, a housing chamber 010 and a guide hole 011 are provided on the drum gear 01, a driving portion 02 is provided in the housing chamber 010 to be inserted into the guide hole 011 and to be rotatable with respect to the guide hole 011, a driving force transmitting portion 022 is provided on the driving portion 02, a driving force receiving portion 012 is provided on the drum gear, the driving force transmitting portion 022 is engageable with the driving force receiving portion 012 and transmits power to the drum gear 01, a plane moving mechanism 03 (i.e., a cross coupling) is provided between the power receiving head 04 and the driving portion 02 so that the power receiving head 04 is movable in a plane with respect to the driving portion 02, and the plane moving mechanism 03 is provided outside the drum gear 01 so that the power receiving head 04 has a larger moving range than the slide plate 04, the slide plate 3506, and the slide plate 04 is movably engaged with the power receiving head 06, and the process cartridge is provided in a process cartridge 06, and is mounted on the end cover plate 06.

As shown in fig. 26, the drum gear 01 is provided with a driving force receiving part 012 and positioning posts 014, the driving force receiving part 012 is symmetrically arranged in the accommodating chamber 010, the positioning posts 014 are arranged in the accommodating chamber 010, the driving part 02 is sleeved with a reset element 07, and an end of the driving part 02 is connected with the head 031, a end of the reset element 07 is sleeved on the driving force transmitting part 022, and another end is sleeved on the positioning posts 014, so that the reset element 07 can provide a restoring force for the driving part 02, the driving force transmitting part 022 can be meshed with the driving force receiving part 012 and transmit the driving force to the driving force receiving part 012.

As shown in fig. 27, when the power receiving head 04 does not receive the rotational force, the positional relationship between the driving force transmitting portion 022 and the driving force receiving portion 012 of the driving portion 02 is as shown in the figure, that is, the driving force transmitting portion 022 is located between the two driving force receiving portions 012 (optimally located at the middle of the two driving force receiving portions 012), and then the power receiving head 04 can rotate clockwise or counterclockwise around its axis in the direction of the arrow shown in the figure. In this embodiment, the rotation angle of the driving force transmitting portion 022 in the clockwise or counterclockwise direction is set to 30 to 85 °, preferably 60 to 80 °, so that a sufficient rotation space of the power receiving head 04 can be secured when engaging with the power applying member 09.

As shown in fig. 28 to 30, at least two pawls 041 are arranged on the power receiving head 04, and the pawls 041 are symmetrically arranged. The driving force applying member 09 (i.e., the printer main body driving shaft) is provided with a rotational force applying arm 091 and a spherical end portion 092. When the driving force receiving head 04 is moved in the arrow direction shown in fig. 28 to approach the power applying member 09 and abut against the power applying member 09, when the pawls 041 abut against the rotational force applying arms 091 or the spherical end portions 092, the power receiving head 04 can be rotated in the direction of its own axis to rotate the power receiving member 04 to the state shown in fig. 30, i.e., the pawls 041 avoid interfering with the rotational force applying arms 091 or the spherical end portions 092 to disable the power receiving head 04 from engaging with the power applying member 09. The power applying member 09 can pass through the middle portion of the U-shaped power receiving head 04 without interfering with the pawl 041.

With the above-described mechanism, the engagement of the power receiving head 04 with the power applying element 09 can be made smoother.

Example four:

the same structure as that of the embodiment will not be described repeatedly, but as shown in fig. 31, the present embodiment is different from the third embodiment in that the end of the reset element 07 is fitted over the driving force transmitting portion, and the other end is provided in a D-shape, and the guide hole 011 on the drum gear 01 is provided in a circular shape in its inner hole (so that the driving portion 02 can freely rotate in the inner hole) and in a D-shape in its outer circumference so as to mesh with the D-shaped structure on the reset element 07, and by providing the reset element 07 thus configured, the effect of providing the restoring force to the driving portion can be also achieved.

In another modes of this embodiment, both ends of the restoring element 07 may be provided with D-shapes, and a D-shaped structure with the same size as the D-shape on the restoring element 07 is provided on the driving portion 02, so that the D-shape on the restoring element 07 is sleeved on the D-shape on the driving portion 02 to provide a restoring force for the driving portion 02, and the driving force transmitting portion 022 is located between the two driving force receiving portions 012.

Example five:

the fifth embodiment is shown in fig. 32-39, the structure and connection relation of the power receiving head 04, the universal joint 03, the driving part 02, and the drum gear 01 are substantially the same as those of the third embodiment, that is, the power receiving head 04 is provided with a U-shape, and jaws 041 are respectively provided at both ends of the U-shape, and the power receiving head 04 transmits power to the drum gear 01 through the universal joint 03 and the driving part 02, except that a bottom surface 042 and a plurality of bottom surface teeth 0421 are provided on the bottom surface 042, the bottom surface 042 is provided with a substantially circular shape, and the bottom surface 042 is provided below the U-shape in the axial direction, and the bottom surface teeth 0421 are provided on the outer circumference of the bottom surface, as shown in fig. 33, the bottom surface teeth 0421 are provided with a plurality of teeth, and are respectively symmetrically provided on both sides of the bottom surface 042, and the connecting line between the centers of the bottom surface teeth 0421 and the jaws 041 is perpendicular to each other, and the bottom surface teeth 0421 are provided with an included angle of two teeth 3560-60 degrees, preferably between the same side teeth -60 degrees.

In this embodiment, the power receiving element is also provided with a cross coupling structure to connect the power receiving head 04 to the driving portion 02, so that the power receiving head 04 can move in a plane perpendicular to the axis thereof, and can transmit power to the drum gear to drive elements such as the developing element in the process cartridge.

As shown in FIG. 34, a rotation control member such as a rack 2a is provided on the side of the process cartridge adjacent to the power receiving element, the rack 2a is provided below the power receiving head 04, a tooth 2a1 is further provided on the rack 2a, a tooth 2a1 is provided on the side of the driving part axis and downstream in the mounting direction of the process cartridge, and the tooth 2a1 is adjacent to but does not abut against the outer circumference of the bottom surface 042 of the power receiving head 04.

As shown in fig. 34, when the power receiving head 04 is in the state shown by the dotted line, the line connecting the two pawls 041 is in a position substantially perpendicular to the mounting direction (shown by the arrow in the figure), and the line connecting the centers of the bottom teeth 0421 is in a position substantially parallel to the mounting direction. Since the power receiving head 04 is relatively movable with respect to the driving portion 02, when the power receiving head 04 is moved in the mounting direction (i.e., from the position indicated by the broken line to the position indicated by the solid line), the axial center of the power receiving head 04 and the axial center of the driving portion are moved from a position (position indicated by the broken line) where they substantially overlap each other to a position (position indicated by the solid line) where they are parallel to each other, and at this time, the teeth 2a1 on the rack are not engaged with the bottom teeth 0421, and therefore, the power receiving head 04 is not rotated.

When the power receiving head 04 is in the state shown in fig. 35, an angle a is formed between a connecting line between the two pawls 041 and the installation direction (shown by the arrow in the figure), and a is not equal to 90 °. At this time, when the power receiving head 04 is moved in the mounting direction (i.e., moved from the position indicated by the broken line to the position indicated by the solid line in the figure), that is, the axial center of the power receiving head 04 and the axial center of the driving portion are moved from the position (the position indicated by the broken line in the figure) at which they substantially overlap each other to the position (the position indicated by the solid line in the figure) at which they are parallel to each other, the bottom teeth 0421 are engaged with the teeth 2a1 on the rack, and the power receiving head 04 is rotated clockwise in the direction indicated by the arrow in the figure by the action of the teeth 2a1 on the rack, so that the power receiving head 04 is finally rotated to the state indicated by the solid line in the figure 36, that is, the line connecting the two. When the power receiving head 04 is moved in the direction of the arrow shown in the figure, the teeth 2a1 on the rack are no longer engaged with the bottom teeth, so that the power receiving head 04 can be moved from the solid line state shown in the figure to the broken line state shown in the figure without the power receiving head being rotated.

Fig. 37-39 show another embodiments of the rotation control member, fig. 37 shows that the rotation control member is disposed above the power receiving head 04, the rotation control member of the present embodiment is a swing rod 2b and an elastic element 2c, the swing rod 2b is connected with the elastic element 2c, the elastic element 2c provides elastic restoring force for the swing rod 2b, the swing rod 2b is further provided with a swing rod acting part 2b1, the swing rod acting part 2b1 is disposed on the side of the driving part axis and is located downstream in the mounting direction (shown by the arrow in the figure) and is close to the outer circumferential surface of the bottom surface 042, the side of the swing rod acting part 2b1 located upstream in the mounting direction is an inclined surface, and the side located downstream in the mounting direction is a straight surface.

As shown in fig. 37, when the power receiving head 04 is in the state shown by the dotted line, the line connecting the two pawls 041 is in a position substantially perpendicular to the mounting direction (shown by the arrow in the figure), and the bottom teeth 0421 are in a position substantially parallel to the mounting direction; when the power receiving head 04 is moved in the mounting direction (i.e., from the position shown by the broken line to the position shown by the solid line), the bottom teeth 0421 do not engage with the swing lever acting portion 2b1, and therefore the power receiving head 04 does not rotate.

When the power receiving head 04 is in the state shown in fig. 38, an angle a is formed between a connecting line between the two pawls 041 and the installation direction (shown by the arrow in the figure), and a is not equal to 90 °. At this time, when the power receiving head 04 is moved in the mounting direction (i.e., moved from the position indicated by the broken line to the position indicated by the solid line), the power receiving head 04 cannot be rotated clockwise in this state, and therefore the bottom teeth 0421 are engaged with the inclined surfaces of the swing lever acting portion 2b1, whereby the swing lever 2b is swung upward in the direction indicated by the arrow to be away from the bottom teeth 0421.

When the power receiving head 04 is moved in the reverse direction of the mounting direction (indicated by the arrow) (i.e., from the position indicated by the broken line to the position indicated by the solid line in fig. 39), the straight surface of the lever action portion 2b1 engages with the bottom teeth 0421, so that the power receiving head 04 is rotated in the direction indicated by the solid line in fig. 39, and finally rotated to the state indicated by the solid line in fig. 39, i.e., the line connecting the two pawls 041 is at a position substantially perpendicular to the mounting direction (indicated by the arrow). The swing lever action portion 2b1 returns to the initial position by the elastic member 2 c.

It will be readily understood by those skilled in the art that the line connecting the two pawls 041 is in a substantially perpendicular position to the mounting direction (shown by the illustrated arrow), and not strictly perpendicular, but rather is understood to be a position where the bottom teeth 0421 on the power receiving head 04 do not interfere with the rotational control member.

Example six:

the same mechanisms and connection relationships as those in the fifth embodiment are not described again in this embodiment.

In this embodiment, the power receiving head 04 is directly connected to the driving part 02, the power receiving head 04 is coaxial with the driving part 02, and the driving part 02 can rotate at a certain angle relative to the drum gear 01. similarly to the third embodiment, the driving part 02 is provided with a driving force transmitting part 022, the drum gear is provided with a driving force receiving part 012, the driving force transmitting part 022 can mesh with the driving force receiving part 012 and transmit power to the drum gear 01, and the driving part 02 can rotate at an angle, which may be 30-170 °, preferably 80-120 °, relative to the drum gear 01 in the drum gear 01.

In the present embodiment, as shown in fig. 40, the rotation control member on the process cartridge is the push rod 2d and the return member 2e, the push rod 2d is provided with the tooth portion 2d1 and the toothless portion 2d 2. the push rod 2d is disposed above the power receiving head 04, the return member 2e is disposed on the side of the push rod 2d and provides the return force to the push rod 2 d. in the initial state shown in fig. 40, the line connecting the two pawls 041 on the power receiving head 04 is in a substantially perpendicular position to the mounting direction (shown by the arrow in the drawing), and the line connecting the centers of the bottom teeth 0421 on both sides is parallel to the mounting direction, and the bottom teeth 0421 on both sides sandwich the tooth portion 2d1 on the push rod 2d, so that when the push rod 2d is not subjected to an external force, the push rod 2d is always in the position shown by the return member 2e, and the tooth portion 2d1 on the push rod 2d restricts the rotation of the bottom teeth 0421 on both sides, thereby ensuring that the power receiving head 04 remains in the initial state to be engaged with the process cartridge 2d to enable the power receiving head 04 to be mounted to the process cartridge 1 well as shown in the state.

When the process cartridge upper 2 is mounted to the main unit 1 in the mounting direction indicated by the arrow in fig. 41 with the power receiving head 04 in fig. 40, the push rod 2d abuts against the front wall 1a on the main unit 1, and the front wall 1a provides a pushing force to the push rod 2d, thereby moving the push rod 2d in the reverse direction of the mounting direction (the direction indicated by the arrow in the drawing), and at this time, the return member 2e is compressed. When the process cartridge 2 is mounted to the main body at the operating position, the process cartridge 2 is in a state shown in fig. 41 in which the toothless portion 2d2 on the push lever 2d is above the power receiving head 04 and the toothless portion 2d2 is not within the rotational range of the bottom teeth 0421 (i.e., the bottom teeth 0421 do not abut on or interfere with the toothless portion 2d2 when the power receiving head 04 rotates), at which time the teeth portion 2d1 is no longer sandwiched by the bottom teeth 0421 on both sides of the power receiving head 04 on both sides and is not within the rotational range of the bottom teeth 0421 (i.e., the bottom teeth 0421 do not abut on or interfere with the teeth portion 2d1 when the power receiving head 04 rotates). In this state, the power receiving head 04 is engaged with the power applying member 09 and receives the driving force to rotate.

When the power receiving head 04 is stopped and the angle between the line connecting the two pawls 041 on the power receiving head 04 and the mounting direction (the direction indicated by the arrow in fig. 41) is a and a is equal to 90 ° (i.e., the power receiving head 04 is in the state shown in fig. 41), the process cartridge 2 is detached from the main unit 1 (detached in the direction opposite to the arrow shown in the drawing), and at this time, since the bottom teeth 0421 on both sides of the power receiving head 04 are not within the range of movement of the tooth portion 2d1 on the push rod 2d, when the process cartridge 2 is detached from the main unit 1, the push rod 2d is no longer subjected to the external force from the front wall 1a and is moved in the arrow shown direction by the restoring member 2e, the tooth portion 2d1 on the push rod 2d is not engaged with the bottom teeth 0421, and therefore the bottom teeth 0421 and the power receiving head 04 are not rotated, and finally, the power receiving head returns to the state shown in fig. 40, and the process cartridge 2 is mounted on the main unit 1 waiting for a number of times .

When the power receiving head 04 is stopped and the angle between the line connecting the two pawls 041 on the power receiving head 04 and the mounting direction (direction indicated by arrow in fig. 41) is a and a is not equal to 90 °, taking as an example the case where the power receiving head 04 is in the state shown in fig. 42, when the process cartridge 2 is detached from the main body 1, the push rod 2d is no longer subjected to an external force from the front wall 1a and moves in the direction of arrow shown in the drawing under the action of the return member 2e, because the bottom teeth 0421 on the side of the bottom teeth 0421 on both sides on the power receiving head 04 are in the range of movement of the tooth portion 2d1 on the push rod 2d, the push rod 2d is no longer subjected to an external force from the front wall 1a, and is moved in the direction of arrow shown in the drawing under the action of the return member 2e, so that the tooth portion 2d1 on the push rod 2d abuts against and engages with the bottom teeth 0421, whereby the bottom teeth 0421 and the power receiving head 04 are completely detached from the main body 1, when the power receiving head 04 is in the state shown in which the power receiving head 042 d is completely detached from the main body 042, the power receiving head 042, the state where the power receiving head 04 is stopped, the power receiving head 04 is not subjected to be completely removed from the bottom teeth 042 d of the main body 042, and the push rod 2, and the power receiving head 042, the power receiving head 042 d, the power receiving head 042, the power.

When the rotation of the power application element 09 is stopped and the power receiving head 04 is in the state shown in fig. 42a, since the side bottom teeth 0421 of the bottom teeth 0421 on both sides of the power receiving head 04, which are located upstream in the mounting direction, are within the range of movement of the tooth portion 2d1 on the push rod 2d, when the process cartridge 2 is detached from the main body 1, the push rod 2d is no longer subjected to an external force from the front wall 1a and is moved in the direction of the arrow shown by the action of the return element 2e, the tooth portion 2d1 on the push rod 2d abuts and engages with the bottom teeth 0421, so that the bottom teeth 0421 and the power receiving head 04 are rotated in the direction of the arrow shown in fig. 42a, when the tooth portion 2d1 on the push rod 2d is engaged with the teeth 0421 on the bottom face, which are farthest from the side of the , the angle B between the tooth 0421 on the push rod 2d is larger than the angle between the tooth portions 2d of the bottom teeth 0421 on the push rod 2d, so that when the tooth portion 2d on the push rod 2d is rotated in the direction of the push rod 2d from the bottom teeth 0421, the bottom teeth 0421 a, the end of the power receiving head 04, the push rod 2d is rotated in the state shown by the direction of the vertical to the push rod head 042 d, the end of the push rod 2d, which is substantially equal to the push rod 2d, which is the power receiving head 042 d, so that the end of the push rod 2d, which is rotated end of the push rod.

In this embodiment, kinds of elements having good elasticity and capable of returning to the original state are used as the trigger element 2f, and the elements can swing and stretch with a small amplitude (similar to elements such as a spring, an elastic steel sheet, or an elastic silicone rubber).

As shown in fig. 45, when the process cartridge 2 is mounted to the main body 1, the axis X2 of the power receiving member 20 is parallel to the axis X1 of the power applying member 10, and the triggering member 2f faces the middle of the triggered mechanism 1 b.

As shown in fig. 46, when the process cartridge 2 is mounted to the main body in the working position, the power receiving member 20 engages with the power applying member 10 and transmits power, with the axis of the power receiving member 20 substantially coinciding with the axis of the power applying member 10.

As shown in FIG. 47, when the process cartridge 2 is detached from the main unit 1, the process cartridge 2 is tilted with respect to the main unit with the axis X2 of the power receiving element 20 being at an angle to the axis X1 of the power applying element 10, and the triggering element 2f can swing, so that the triggering element 2f can swing to the state shown in FIG. 48. when the process cartridge 2 is completely detached from the main unit 1, the triggering element 2f returns to its original state, i.e., the state shown in FIG. 45, and the triggering element 2f on the process cartridge 2 waits for times to be used.

As shown in fig. 49, when the power receiving head 04 is engaged with the power applying member 09, the driving portion 02 is moved in the direction approaching the power applying member 09 by the elastic member 07a with a gap from the drum gear 01, and the pressing end 06a on the slide plate 06 does not provide the pressing force to the pressed end 08a on the pressing lever 08.

When the process cartridge is detached from the image forming apparatus, the process cartridge is pulled, the power receiving head 04 and the power receiving head 04 move in a direction perpendicular to the axial direction of the power receiving head 04 (as shown in the direction Y in fig. 50) due to the engagement between them, the slide plate 06 moves with the power receiving head 04 , while the push rod 08 does not move with the power receiving head 04 , so that there is relative movement between the slide plate 06 and the push rod 08 at this time, the slide plate 06 presses the pressed end 08a on the push rod 08 by the contact end 06a during the movement, thereby moving the push rod 08 in the axial direction of the power receiving head 04 (the direction X shown in fig. 50), and the drive portion 08b pushes the drive portion 02 to move in its axial direction (the direction X in the drawing) due to the contact between the push end 08b on the push rod 08 and the drive portion 02, thereby moving the drive portion 02 in the direction X close to the drum gear 01, and finally the drive portion 04 and the power receiving head 04 moves in the axial direction X04 (the power receiving head 04 is moved in the direction X04), thereby disengaging the power receiving head 04 from the power receiving head 04 (the power receiving head 04).

Example nine:

in this embodiment, the same portions as those in embodiment eight will not be described repeatedly.

As shown in fig. 52, the present embodiment does not include the elastic member 07a between the driving portion 02 and the drum gear 01 as in the eighth embodiment, and therefore the power receiving head 04 can move in the axial direction X together with the drum gear 01 and the driving portion 02 in the present embodiment.

As shown in fig. 52, the end cover plate 05 is further provided with an ejected element 051 and an elastic element 052; the ejected element 051 extends out of the end cover plate 05, and the elastic element 052 is arranged between the ejected element 051 and the end cover plate 05 and provides elastic restoring force for the ejected element 051.

The ejecting tip 061 may engage the ejected tip 051a to provide force to the ejected element 051 and to cause the ejected element 051 to extend from the end cap plate 05.

As shown in fig. 53, when the power applying element 09 is engaged with the power receiving head 04, the power receiving head 04 and the power applying element 09 move in the Y direction shown in the figure, the sliding plate 06 and the power receiving head 04 move, so that the ejection end 06 on the sliding plate 06 presses the ejected end 051a on the ejected element 051, the ejected element 051 is pressed by the ejection end cover 05 and the right wall 10c in the image forming apparatus, and the ejection element 051 presses the right wall 10c, so that the sliding plate 06 drives the end cover 05, the drum gear 01, and the power receiving head 04 to move in the X direction in the figure, and further the power receiving head 04 is disengaged from the power applying element 09.

In this embodiment, the cartridge may be provided with an elastic member (e.g., a spring) at the end opposite to the power receiving head 04, and the spring may provide a force in the direction opposite to the direction X in FIG. 53 for the cartridge, when the power receiving head 04 is disengaged from the power applying member 09 in the state shown in FIG. 53, the power applying member 09 no longer provides a force in the direction Y in FIG. 53 for the power receiving head 04, and the cartridge may provide a force in the direction opposite to the direction X in FIG. 53 for the cartridge under the action of the elastic member, so that the cartridge moves in the direction opposite to the direction X in the figure, and the power receiving head 04 and the cartridge move in the direction opposite to the direction X.

Example ten:

in this embodiment, the same structures, connection relationships, and the like as those in the ninth embodiment will not be described again.

As shown in fig. 55, in the present embodiment, a lever element 053, an ejected element 054, and an elastic element 055 are provided in the end cover plate 05. The lever element 053 is provided with a rotating shaft, which is provided on the end cover plate 05, and the lever element 053 can rotate around the rotating shaft.

When the power receiving head 04 moves in the Y direction shown in fig. 56 with the power applying element 09 , the sliding plate 06 moves in the Y direction with the power receiving head 04, the sliding plate 06 then presses the end of the lever element 053 and rotates the rigid element 053 around its rotation axis (from the state shown in fig. 55 to the state shown in fig. 56), the other end of the rotated lever element 053 presses the ejected element 054, so that the ejected element 054 protrudes further out of the end cover plate 05 and presses the right wall 10c in the image forming apparatus (at this time, the elastic element 055 located between the ejected element 054 and the end cover plate 05 is in a compressed state), the ejected element 054 moves in the X direction in fig. 56 after being pressed against the right wall 10c by the ejected element 054, the ejected element 053 is driven by the ejected element 054, so that the lever element 3 drives the end cover plate 05, the sliding plate 06, the power receiving head 04, and the drum gear to move in the power receiving head 04 out of engagement with the power applying element 09.

Similarly to the eighth embodiment, an elastic member (e.g., a spring) may be provided on the cartridge at the other end opposite to the power receiving head 04, the spring providing a force to the cartridge in the direction opposite to the direction X in FIG. 53. when the power receiving head 04 is disengaged from the power applying member 09, the elastic member allows the power receiving head to move in the direction opposite to the direction X in FIG. 56.

Example ten :

the image forming apparatus includes an image forming apparatus main body 1, and the main body 1 is provided with a power applying member 10, a front wall 10a, a left wall 10b, a right wall 10c, an upper wall 10d, and a lower wall 10 e.

The process cartridge 2 is provided with a power receiving head 20, left and

right sides

22 and 23, and a pressure receiving member 27. The pressure receiving member 27 is provided on the left side 22. As can be seen, when the process cartridge 2 is mounted inside the main body 1, the pressing member 17 applies pressure to the pressure receiving member 27.

As shown in fig. 59 and 60, the pressure receiving member 27 is provided with a sliding element 27a and a fixed element 27b, both of which are cylindrical, and as can be seen from the figure, the fixed member 27b is fixed on the left side 22, and the sliding element 27a can slide back and forth on the fixed element 27b, as shown in fig. 59, when the process cartridge is mounted in the main unit, the pressure receiving member 17 applies a pressure F to the pressure receiving member 27, and at this time, the sliding element 27a and the fixed element 27b are completely overlapped, when the process cartridge 2 moves in the X2 direction, the sliding element 27a is pressed by the pressure receiving member 17, and therefore, the sliding element 27a does not move with the process cartridge , and the fixed element 27b is fixed on the left side 22 on the process cartridge, and therefore, the fixed element 27b moves with the process cartridge , and at this time, the pressure receiving member 17 applies a pressure to the process cartridge through the sliding element 27.

As shown in fig. 61 and 62 which are another types of the present embodiment, the pressure receiving member 27 in the present embodiment is provided as the sliding element 27c and the fixing element 27d, and unlike the above-described form, the sliding element 27c and the fixing element 27d in the present embodiment are both in a flat plate shape.

It will be readily apparent to those skilled in the art that other shapes of the sliding and fixing elements in the pressure receiving member 27 may be employed.

Example twelve:

as shown in FIGS. 63 and 64, the image forming apparatus is further provided with a triggered mechanism 1b, the triggered mechanism 1b is provided with th and second triggered rods 1b1 and 1b2, and th and second triggered rods 1b1 and 1b2 are arranged in a staggered manner, the triggered mechanism 1b is arranged on the upper wall 10d of the main body, the triggered mechanism 1b is rotatably supported by a partition board 1c, and the processing box 2 is provided with th and second triggering members 2f1 and 2f 2.

As shown in fig. 65, the th and second triggering members 2f1 and 2f2 are disposed on the upper side of the process cartridge, and are spaced apart from each other by a distance of in the axial direction and the direction perpendicular to the axial direction (i.e., offset in the direction X, Y).

As shown in FIG. 66, when the process cartridge 2 is not mounted on the main unit 1, the th triggering element 2f1 is downstream in the Y direction, while the th triggered rod 1b1 is in the vertical direction in the figure and the second triggered rod 1b2 is in the horizontal direction in the figure, when the process cartridge moves in the Y direction in the figure, the th triggering element 2f1 drives the th triggered rod 1b1 and rotates the triggered mechanism 1b to the state shown in FIG. 67, and when the process cartridge continues to move in the Y direction, the second triggering element 2f2 drives the second triggered rod 1b2 and rotates the triggered mechanism 1b to the state shown in FIG. 68.

Example thirteen:

the structure and connection relationship in this embodiment are the same as those in the twelfth embodiment, and the description thereof will not be repeated.

As can be seen from FIG. 69, when the th trigger element 2f1 and the second trigger element 2f2 on the process cartridge abut against the th triggered rod 1b1 and the second triggered rod 1b2 on the main unit, respectively, the th trigger element 2f1 and the second trigger element 2f2 are inserted between the partition boards 1c, respectively, and at this time, the power receiving head 20 on the process cartridge engages with the power applying element 10 on the main unit, and the axial direction X2 of the power receiving head 20 coincides with the axial direction X1 of the power applying element 10.

When the process cartridge needs to be detached from the main unit, the process cartridge rotates in the direction of the arrow in fig. 70, and at this time, an included angle exists between the axial direction X2 of the power receiving head 20 of the process cartridge and the axial direction X1 of the power applying element 10, at this time, since the ends of the th trigger element 2f1 and the second trigger element 2f2 are both located between the two partition boards 1c, the th trigger element 2f1 and the second trigger element 2f2 are both inclined (in this embodiment, the th trigger element 2f1 and the second trigger element 2f2 are both made of soft materials, and therefore, no breakage occurs after the inclination.

Another forms of this embodiment is that as shown in FIGS. 71 and 72, the main body of the image forming apparatus may further be provided with an electrical contact mechanism 1d, the electrical contact mechanism 1d being provided on the upper wall 10d of the main body, and the process cartridge may be provided with an electrical element support 2 g. as shown in FIG. 71, when the process cartridge is mounted on the main body, there is spacing (no engagement) between the power receiving head 20 and the power applying element 10, the triggering element 2f is inserted between the spacers 1c and abuts against the triggered mechanism 1b between the spacers 1c, and the triggered mechanism 1b is rotated, the electrical element support 2g on the process cartridge abuts against the electrical contact mechanism 1d on the main body, and the chip in the electrical element support 2g is brought into contact with the electrical contact mechanism 1d and normally operates, when the process cartridge is moved in the direction of arrow X shown in FIG. 72, there is no spacing (engagement) between the power receiving head 20 and the power applying element 10, and since the electrical element support 2g and the triggering element 2f are both made of soft material, the electrical element support 2g and the triggering element 2f are deformed, and the free ends of the electrical contact mechanism 1d and the triggering mechanism are still in the final state shown in FIG. 72.

As shown in fig. 82, in order to allow the process cartridge 19 on the tray 18 to be returned to the position shown in fig. 79 after both the tray 18 and the process cartridge 19 are pulled out from the image forming apparatus, so that the process cartridge 19 can be mounted in the image forming apparatus in the state shown in fig. 79 from the tray 18 after mounting the process cartridge 19 in the tray 18 next time, the present embodiment may be further provided with an elastic member 21 at the front end (the front end in the mounting direction C1) of the left restricted portion 19b, the elastic member 21 abutting the left pulled-out surface 18d on the left restricted portion 18b after the process cartridge 19 is mounted in the tray 18, and providing an elastic force to the left restricted portion 19b so that the left pulled-out surface 19d moves away from the left pulled-out surface 18d, thereby allowing the left contacted surface 19C to abut the left contacted surface 18C, and of course, a person of ordinary skill in the art can easily conceive of providing an elastic member at the front end of the right restricted portion 19f, and also allowing the process cartridge 19 to be mounted in the right restricted portion 19 and allowing the process cartridge 19 to be mounted in the image forming apparatus in the state shown in the image forming apparatus, and when the image forming apparatus is not shown in fig. 79.

Example fifteen:

the connection relationship and the operation of the mechanism in this embodiment are the same as those in the sixth embodiment, and the description thereof will not be repeated.

As shown in fig. 83, the power receiving head 04 is provided with two pawls 041 and bottom teeth 0421. In the sixth embodiment, two pawls 041 are symmetrically arranged on the power receiving head 04 along the circumferential direction. In this embodiment, the bottom teeth 0421 are provided in two, and are symmetrically provided in the circumferential direction. The line between the two bottom teeth 0421 is perpendicular to the line between the two jaws 041.

As shown in fig. 84a, 84b, the rotation controller on the process cartridge, including the push rod 2d3, the restoring member 2e3, the rotating member 2f3 and the blocking member 2 g3., the push rod 2d3 can be moved in the end cap plate 05, and the end of the push rod 2d3 can receive an external force, and the other end is connected with the restoring member 2e3, and the restoring member 2e3 provides an elastic restoring force to the push rod 2d3, the rotating member 2f3 is connected with the end of the push rod 2d3, and the rotating member 2f3 can be rotated with respect to the push rod 2d3 (e.g., counterclockwise from the state shown in fig. 84a to the state shown in fig. 84 b), the blocking member 2g3 is provided on the end of the push rod 2d3, and the blocking member 2g3 can organize the clockwise rotation of the rotating member 2f 3.

As shown in fig. 85a, the rotation control member is disposed below the power receiving head 04. When the process cartridge is mounted in the image forming apparatus, and when the power receiving head 04 cannot rotate counterclockwise (can rotate clockwise) with respect to the drum gear 01 as shown in fig. 85a, the push rod 2d3 receives an external force F (such as an external force from the image forming apparatus), so that the push rod 2d3 moves leftward in the arrow direction shown in fig. 85b, the rotating member 2F3 cannot rotate clockwise due to being blocked by the blocking member 2g3, and therefore the rotating member 2F3 pushes the bottom teeth 0421 and causes the power receiving head 04 to rotate clockwise.

When the external force F is removed, the restoring member 2e3 provides the pushing rod 2d3 with elastic restoring force to move the pushing rod 2d3 in the direction of the arrow shown in fig. 85c, since the power receiving head 04 cannot rotate counterclockwise, when the bottom teeth 0421 are at the position shown in fig. 85c, the bottom teeth 0421 make the rotating member 2F3 rotate counterclockwise to the state shown in the figure, at the same time, the restoring member 2e3 continues to provide the elastic restoring force to the pushing rod 2d3, and finally the pushing rod 2d3 moves to the position shown in fig. 85a, at which time, the rotating member 2F3 returns to the state shown in fig. 85a under the action of elastic members (such as springs or torsion springs, not shown in the figure).

In this embodiment, when the bottom teeth 0421 adopt a plurality of teeth as shown in the sixth embodiment, the rotation control member of this embodiment can achieve the desired technical effect, and the description thereof is not repeated.
