Fig. 7 to 10 respectively depict the drive assembly in two states. Fig. 7 is a perspective view of the driving assembly in an initial state, and fig. 8 is a sectional view of fig. 7. When the process cartridge is before being mounted to the electronic image forming apparatus, the driving assembly is in a state as shown in fig. 7 and 8; when the process cartridge is mounted in place, the driving assembly is in a state (operating state) as shown in fig. 9 and 10. Before the process cartridge is mounted, the slider 216 is held in the initial state, i.e., the state in which the axis L3 of the slider 216 is offset from the photosensitive-element hub axis L1, by the first elastic member 217 under the action of the natural elongation of the first elastic member 217, and the rotational power receiving member 214 is held in the inner hole 2163 while the axis of the rotational power receiving member 214 is coaxial with the axis L3 of the slider 216, at which time the rotational power receiving member 214 is also offset with respect to the axis L1 of the photosensitive-element hub, i.e., the axis L1 is misaligned with the axis L3 but is relatively parallel thereto; since the intermediate power transmitting member 213 is confined between and in cooperative relationship with the photosensitive element hub 212 and the power transmitting member 214, when the rotational power receiving member 214 is in the initial position shown in fig. 8, the rotational power receiving member 214 urges the intermediate power transmitting member 213 to tilt relative to the axis L1 of the photosensitive element hub, as well as relative to the axis L3 of the rotational power receiving member 214. At this time, the driving assembly is in the initial state, the axis L2 of the intermediate power transmission part 213 is inclined with respect to the axis L1 of the photosensitive element hub and the axis L3 of the rotational power receiving part 214, i.e., included angles are formed between L2 and L1, and between L2 and L3. When the process cartridge is mounted to the electronic image forming apparatus, the sliding member 216 is subjected to an external force F in the direction opposite to the mounting direction of the process cartridge, and the force F causes the sliding member 216 to slide in the slide rail 2151 in the direction opposite to the loading direction of the process cartridge by urging the sliding member 216 against the elastic force of the first elastic member 217; at this time, the rotational power receiving part 214 also moves along with the sliding part 216, and drives the intermediate power transmitting part 213 to gradually swing (i.e. the included angle between L2 and L1, and between L2 and L3 gradually becomes smaller), and the end of the intermediate power transmitting part 213 engaged with the rotational power receiving part approaches to the rotational power receiving part; finally, when the process cartridge is mounted in place, the external force F overcomes the elastic force of the first elastic member 217 and compresses it, so that the intermediate power transmission member 213, the rotational power receiving member 214, and the slider 216 are held in the state shown in fig. 9 and 10, i.e., the operating state of the driving assembly; at this time, the axis L2 of the intermediate power transmitting member, the rotational power receiving member L3 are coaxial with the axis L1 of the photosensitive element hub. Meanwhile, in the process from the initial state to the operating state of the process cartridge loader, the intermediate power transmitting member 213 is tilted to be turned, so that the rotational power receiving member 214 has a certain displacement amount in the longitudinal direction of the process cartridge, that is, the rotational power receiving member 214 is extended in the longitudinal direction of the process cartridge.

Fig. 11a shows the process cartridge in an initial state before loading, in which the driving assembly is in a state in which the intermediate power transmission member 213 is tilted with respect to the axis L1 of the photosensitive element hub and the axis L3 of the rotational power receiving member 214, the axis L3 of the rotational power receiving member 214 is offset with respect to the axis L1 of the photosensitive element hub, and the first elastic member 217 is in a naturally extended state so that the slider 216 is held in the initial state, in which the rotational power receiving member 214 is in a retracted state. When the process cartridge is mounted in the Y direction as shown in the figure, it gradually approaches the inner side 141 of the electrophotographic apparatus, and since the rotational power receiving member 214 is always in the retracted state, the rotational power receiving member 214 does not interfere with the rotational force driving head 11 during the process of mounting the process cartridge; when the process cartridge is mounted, the end surface 2161 of the slider 216 first contacts the inner surface 141 of the electrophotographic apparatus, and the inner surface 141 exerts a force F on the slider 161, which is opposite to the mounting direction Y of the process cartridge, as shown in fig. 11b, the rotational force receiving member 214 is coaxial with the rotational force driving head 11, but still cannot be engaged with each other, and there is no interference therebetween, and the rotational force receiving member is in a retracted state; the process cartridge continues to be mounted, the force F causes the slider 216 to slide in the direction opposite to the Y direction with respect to the photosensitive element 211, and the intermediate power transmitting member 213 is gradually swung by the rotational power receiving member 214, and the intermediate power transmitting member 213 causes the rotational power receiving member 214 to project in the longitudinal direction of the process cartridge during the swing, i.e., the X direction as shown in fig. 11 c. Fig. 11c shows the state in which the cartridge is mounted in place, i.e., the cartridge is in the operating state, in which the rotational force receiving member 214 is brought into engagement with the rotational force driving head 11, and the rotational force driving head 11, the rotational force receiving member 214, and the intermediate power transmitting member 213 are all coaxial with the axis L1 of the photosensitive element hub. When the electronic image forming apparatus is started, the driving gear 13 rotates to drive the rotational force driving head 11 to rotate, thereby transmitting the power to the photosensitive element through the rotational power receiving member 214, the intermediate transmission member 213, and the photosensitive element hub 212 to rotate the photosensitive element.
Fig. 12a to 12c are schematic views showing a process in which the driving assembly is disengaged from the rotational force driving head in the process of detaching the process cartridge from the electronic image forming apparatus. As shown in fig. 12a, the process cartridge is detached from the electrophotographic apparatus in a direction opposite to the mounting direction (Y direction) (i.e., in the illustrated Y' direction). In the process of gradually detaching the process cartridge, since the force F is gradually removed, the direction of the elastic restoring force generated by the first elastic element 217 is opposite to the direction of detaching the process cartridge, and the elastic restoring force generated by the first elastic element 217 acts on the slider 216, so that the intermediate power transmission member 213 is deflected, as shown in fig. 12b, and at the same time, the restoring force of the elastic element causes the slider 216 to slide in the opposite direction of the process cartridge detaching direction in the slide rail 2151, and then the intermediate power transmission member is deflected to drive the rotational power receiving member 214 to retract in the opposite direction of the X direction (i.e., the direction X' shown in the figure) and disengage from the rotational power driving head 11, so that the force F is gradually reduced or even disappears; continuing to disassemble the cartridge, the cartridge is completely removed from contact with the electronic imaging device, as shown in fig. 12 c.
By the embodiment of the embodiment, the process cartridge can be mounted on the electronic imaging device without interfering with the hair driven by the rotating force; during the mounting or dismounting of the process cartridge, the rotational power receiving member 214 does not relatively move with respect to the rotational force driving head 11 in the mounting direction of the process cartridge while the end face of the slider remains in contact with the inner side face of the electronic image forming apparatus; only the rotational power receiving member 214 is relatively moved in the axial direction with respect to the rotational force driving head 11 and is engaged with or disengaged from it, thereby making the process cartridge loading machine smooth.

The process of mounting and dismounting the process cartridge using the driving assembly of the second embodiment to and from the electronic image forming apparatus will be described in detail below.
Fig. 16a to 16c are schematic views showing a process of mounting the process cartridge to the electronic image forming apparatus with the driving assembly engaged with the rotational force driving head. Fig. 16a is a view showing an initial state in which the driving assembly 22 is mounted on the process cartridge 2, the intermediate power transmission member 223 being held in a retracted state by the slider 226, the second elastic member 228 being in a compressed state; the rotational power receiving member 224 is held in a state of being relatively offset from the axis L1 of the photosensitive element hub by the first elastic element 227 and the slider 226. When the process cartridge is mounted in the electronic image forming apparatus in the Y direction, the end surface 2261 of the slider 226 first touches the inner side surface 141 of the electronic image forming apparatus, and at this time, the inner side surface 141 exerts a force F on the slider 226 opposite to the mounting direction of the process cartridge, as shown in fig. 16 b. Continuing to mount the process cartridge, under the action of the force F, the first elastic element 227 is gradually compressed, the sliding member 226 overcomes the elastic force of the first elastic element 227 to slide relatively in the direction opposite to the direction of the cartridge loading machine, and drives the rotary power receiving member 224 to move relatively in the direction opposite to the direction of the cartridge loading machine, and at this time, the intermediate power transmission member approaches the inner side of the electronic image forming apparatus together with the process cartridge along with the mounting of the process cartridge, that is, the intermediate power transmission member 223 moves relatively with the rotary power receiving member 224, and the axes L2 and L3 thereof approach each other; as the process cartridge is mounted, the bottom surface 2264 of the slider 226 is gradually out of contact with the end surface of the intermediate power transmission part 223 during the sliding of the slider 226, and the intermediate power transmission part 223 is projected in the longitudinal direction of the process cartridge (i.e., the illustrated X direction) by the resilient force of the second resilient element 228. When the process cartridge is mounted in place, as shown in fig. 16c, the driving assembly 22 is in an operating state. The intermediate power transmission member 223 is extended in the X direction as shown by the resilient force of the second elastic element 228 and is engaged with the rotational power receiving member 224, and after both are engaged, the intermediate power transmission member is extended continuously and urges the rotational power receiving member 224 to be extended together in the X direction to be engaged with the rotational force driving head 11 provided in the electronic image forming apparatus. At this time, the photosensitive-element hub 222, the intermediate power transmission member 223, the rotational power receiving member 224, and the rotational force driving head 11 are all in a coaxial state. When the electrophotographic apparatus is started, the driving gear 13 drives the rotational force driving head 11 to rotate, and the rotational force driving head transmits power to the rotational force receiving part 224 by engaging with the claws 2241 of the rotational force receiving part 224, transmits the rotational force to the photosensitive element hub by engaging the rotational force receiving part 224 with the intermediate power transmitting part 223 and engaging between the intermediate power transmitting part 223 and the photosensitive element hub, thereby transmitting the rotational force to the photosensitive element hub, and achieving the purpose of driving the photosensitive element to rotate by the photosensitive element hub 222 (the photosensitive element hub and the photosensitive element are in close fit and coaxial).
Fig. 17a to 17c are schematic views showing a process of disengaging the driving assembly from the rotational force driving head in detaching the process cartridge from the electronic image forming apparatus. The process cartridge is removed in the direction opposite to the process cartridge mounting direction (i.e., the illustrated Y' direction), as shown in fig. 17 a. As the process cartridge is removed, the force F of the inner side surface 141 of the electronic image forming apparatus against the slider 226 gradually decreases or disappears, the slider 226 slides in the direction opposite to the process cartridge removing direction by the resilient force of the first resilient member 227, the inclined surface 2263 acts on the intermediate power transmission member 223 and causes it to retract in the direction of the axis L1, while the second resilient member 228 is compressed; during retraction of the intermediate power transmission member 223, the intermediate power transmission member is gradually disengaged from the rotary power transmission member 224, and when the bottom surface 2264 of the slider 226 abuts against the end surface of the intermediate power transmission member 223, the intermediate power transmission member can be maintained in a retracted state; after the intermediate power transmission member 223 is disengaged from the rotational power receiving member 224, the rotational power transmission member 224 is retracted in the opposite direction to the X direction (i.e., the illustrated X' direction) by the third elastic member 229, as shown in fig. 17 b. Continuing to remove the cartridge, the cartridge is completely removed from contact with the electronic imaging device, as shown in fig. 17c, enabling the process to be removed from the electronic imaging device.

The process of mounting and dismounting the process cartridge using the driving assembly of the third embodiment to and from the electronic image forming apparatus will be described in detail below.
Fig. 20a to 20c are schematic views showing a process of mounting the process cartridge to the electronic image forming apparatus with the driving assembly engaged with the rotational force driving head. Fig. 20a is a view showing the driving unit 23 in an initial state, in which the axis of the rotational power receiving member 234 is L3, in which case the axis L3 is offset with respect to the axis L1 of the hub of the photosensitive element and the axis L2 of the intermediate power transmission member, and the process cartridge is mounted in the direction Y shown in the drawing, and in which the rotational power receiving member 234 is in a retracted state such that the rotational power receiving member 234 does not interfere with the rotational power driving head 11 provided in the electrophotographic apparatus when the process cartridge is mounted. As shown in fig. 20a, 12 is a right side wall of the electronic imaging device, 14 is a rear side wall of the electronic imaging device, a rotational force driving head 11 is arranged on the right side wall 12, and a driving gear 13 is used for driving the rotational force driving head 11 to rotate. When the process cartridge is mounted in the Y direction, the end face 2361 of the slider 236 first comes into contact with the rear side 141 of the electronic image forming apparatus, and the rear side wall 14 exerts a force F on the slider 236, as shown in fig. 20 b. The process cartridge continues to be mounted, causing the slider 236 to slide in the direction opposite to the direction of the process cartridge loading machine under the action of the force F, and gradually causing the first elastic member 237 to compress; when the slider 236 moves to a certain extent and the bottom surface 2365 thereof is out of contact with the intermediate link 2331, the intermediate power transmission member 233 is allowed to extend in the direction of the axis L1 of the hub of the photosensitive element by the resilient force of the second elastic element 238 while pushing the rotary power receiving member 234 to extend in the longitudinal direction of the cartridge (i.e., the X direction in the figure); when the process cartridge is mounted in position, the rotational power receiving member 234 is extended to engage with the rotational force driving head 11 in the electronic image forming apparatus, as shown in fig. 20c, i.e., the driving assembly is in an operating state. After the electronic imaging device is started, the driving gear 13 drives the rotational force driving head 11 to rotate and drives the rotational force receiving part 234 to rotate, so that the photosensitive element hub 232 is driven to rotate through the intermediate power transmission part, and finally the photosensitive element arranged in the processing box is driven to rotate through the photosensitive element hub 232. At this time, the axes of the photosensitive element 231, the photosensitive element hub 232, the intermediate power transmitting member 233, the rotational power receiving member 234, and the rotational force driving head 11 are in a substantially coaxial state.
Fig. 21a to 21c are schematic views showing a process of disengaging the driving assembly from the rotational force driving head in detaching the process cartridge from the electronic image forming apparatus. As shown in fig. 21a, the process cartridge is detached from the electrophotographic apparatus in a direction opposite to the process cartridge mounting direction (i.e., the illustrated Y' direction). As the process cartridge moves, the force F of the rear side wall 14 against the slider 236 gradually decreases or even disappears, and the slider 236 moves in the opposite direction to the process cartridge removing direction by the resilient force of the first elastic member 237 and drives the rotational power receiving member 234 to slide, so that the rotational power receiving member 234 is displaced with respect to the axis of the intermediate power transmitting member 233; meanwhile, during the sliding of the slider 236, the inclined surface 2364 thereof abuts against a portion on the intermediate power transmission member 233, causing the intermediate power transmission member 233 to retract against the elastic force of the second elastic element 238, while the intermediate power transmission member 233 drives the rotational power receiving member 234 to retract in the direction X' shown in fig. 21b during the movement with the process cartridge. As shown in fig. 21b, the driving assembly 23 is restored to the initial state, the rotational power receiving part 234 is disengaged from the rotational force driving head 11 of the electronic image forming apparatus, and the process cartridge is smoothly detached from the electronic image forming apparatus as shown in fig. 21 c.
In the aspect of the present invention, if the distance from the axis L4 of the rotational force driving head 11 in the electronic image forming apparatus to the inner side 141 in the electronic image forming apparatus is h1, since the rotational force receiving part 214(224 or 234) is projected in the longitudinal direction of the process cartridge to engage with the rotational force driving head 11 for power transmission, in order to ensure smooth engagement therebetween, the distance h2 from the axis L3 of the rotational force receiving part to the end surface 2161(2261 or 2361) of the slider 216(226 or 236) is set to be equal to h1, as shown in fig. 11a and 11 b. The distance from the axis L4 of the rotary force driving head 11 in the electronic imaging device to the inner side surface 141 in the electronic imaging device is h1, namely the distance from the axis L4 to the acting point of the external acting force F.
By the embodiment of the invention, the process cartridge can be smoothly installed in the electronic imaging device without interfering with a rotary force driving head of the electronic imaging device to cause the problem that the process cartridge cannot be installed in place.
