7 to 10 respectively describe the two states of the driving assembly. FIG. 7 is a perspective view of the initial state of the driving assembly, and FIG. 8 is a cross-sectional view of FIG. 7 . Before the process cartridge is mounted on the electronic imaging device, the drive assembly is in the state shown in Figure 7 and Figure 8; after the process cartridge is installed in place, the drive assembly is in the state (working state) shown in Figure 9 and Figure 10. Before the process cartridge is installed, under the action of the natural elongation of the first elastic member 217, the sliding member 216 is kept in the initial state by the first elastic member 217, that is, the axis L3 of the sliding member 216 deviates from the hub axis L1 of the photosensitive element state, and the rotational power receiving part 214 is held in the inner hole 2163, while the axis of the rotational power receiving part 214 is coaxial with the axis L3 of the slider 216, and the rotational power receiving part 214 also follows the sliding part 216 relative to the The axis L1 of the photosensitive element hub is offset, that is, the axis L1 and the axis L3 are not coincident but relatively parallel; because the intermediate power transmission part 213 is limited between the photosensitive element hub 212 and the power transmission part 214, and has mutual cooperation with the two relationship, when the rotational power receiving member 214 is in the initial position shown in FIG. The axis L3 is tilted. At this time, the driving assembly is in the initial state, and the axis L2 of the intermediate power transmission part 213 is inclined relative to the axis L1 of the hub of the photosensitive element and the axis L3 of the rotating power receiving part 214, that is, there are formed between L2 and L1, and between L2 and L3. angle. When the process cartridge is installed in the process of the electronic imaging device, the sliding member 216 is subjected to an external force F along the opposite direction of the process cartridge installation direction, and the force F makes the slide by driving the sliding member 216 to overcome the elastic force of the first elastic member 217 The part 216 slides in the slide rail 2151 along the opposite direction of the process cartridge loading direction; at this time, the rotating power receiving part 214 also moves along with the sliding part 216, and drives the intermediate power transmission part 213 to gradually align (that is, L2 and The included angle between L1, L2 and L3 gradually becomes smaller), and one end of the intermediate power transmission member 213 engaged with the rotating power receiving member approaches the rotating power receiving member; finally, when the process cartridge is installed in place , the external force F overcomes the elastic force of the first elastic element 217 and compresses it, so that the intermediate power transmission part 213, the rotational power receiving part 214 and the slider 216 remain in the state shown in Figures 9 and 10, that is, the drive assembly Working state: at this time, the axis L2 of the intermediate power transmission part, the rotational power receiving part L3 and the axis L1 of the hub of the photosensitive element are coaxial. Simultaneously, during the process from the initial state to the working state of the process cartridge loading machine, the intermediate power transmission member 213 is tilted to right, so that the rotating power receiving member 214 has a certain amount of displacement in the longitudinal direction of the process cartridge, so that The rotational power receiving member 214 protrudes in the longitudinal direction of the process cartridge.

11a to 11c are schematic diagrams showing the process of installing the process cartridge into the electronic imaging device and engaging the driving assembly with the rotational force driving head. As shown in Figure 11a, 11 is the rotational force driving head arranged in the electronic imaging device, 13 is the driving gear that drives the rotational force driving head 11 to rotate, 12 is the right side wall of the electronic imaging device, and 14 is the rear side of the electronic imaging device Wall, wherein the rotational force driving head 11 and the driving gear 13 are all arranged on the right side wall 12 of the electronic imaging device, and 141 is the inner surface opposite to the installation direction of the process box on the rear side wall 14 . Figure 11a shows the initial state of the drive assembly before the process cartridge is installed, the middle power transmission part 213 is inclined relative to the axis L1 of the hub of the photosensitive element and the axis L3 of the rotational power receiving part 214, and the rotational power receiving part 214 is tilted. The axis L3 is offset relative to the axis L1 of the hub of the photosensitive element, and the first elastic member 217 is in a state of natural extension so that the slider 216 remains in an initial state, and the rotational power receiving member 214 is in a retracted state. When the process cartridge is installed along the Y direction shown in the figure, and gradually approaches the inner surface 141 of the electronic imaging device, since the rotating power receiving part 214 is always in a retracted state, the rotating power receiving part 214 will not be driven by the rotating force during the process of installing the process cartridge. The head 11 interferes; the installation of the process cartridge continues, and the end face 2161 of the slider 216 first touches the inner side 141 of the electronic imaging device, and the inner side 141 produces a force F on the slider 161, and the direction of action of the force F is the same as that of the electronic imaging device. The installation direction of the process cartridge is opposite to the Y direction, as shown in Figure 11b, at this time, the rotational power receiving part 214 is coaxial with the rotational force driving head 11, but still fails to mesh with each other, there is no interference between them, and the rotational power receiving part is in the retracted state; the process box continues to be installed, and the force F impels the sliding member 216 to slide relative to the photosensitive element 211 along the opposite direction of the Y direction, and drives the middle power transmission part 213 to be gradually aligned by rotating the power receiving part 214, and the middle power transmission part 213 The rotational power receiving member 214 is urged to protrude in the longitudinal direction of the process cartridge, ie, the X direction as shown in FIG. 11c, during the straightening process. Figure 11c shows the state that the process box is installed in place, that is, the process box is in the working state. At this time, the rotating power receiving part 214 is engaged with the rotating force driving head 11, and the rotating force driving head 11, the rotating power receiving part 214, and the intermediate power transmission The members 213 are all coaxial with the axis L1 of the photosensitive element hub. When the electronic imaging device is started, the driving gear 13 rotates to drive the rotational force driving head 11 to rotate, so that the power is transmitted to the photosensitive element by rotating the power receiving part 214, the intermediate transmission part 213 and the photosensitive element hub 212, so that the photosensitive element rotates.

12a to 12c are schematic diagrams showing the disengagement process of the drive assembly from the rotational drive head during the process of disassembling the process cartridge from the electronic imaging device. As shown in Fig. 12a, the process cartridge is detached from the electronic image forming apparatus in a direction opposite to the mounting direction (Y direction), that is, in the illustrated Y' direction. During the process of dismounting the process cartridge gradually, due to the gradual withdrawal of the force F, the direction of the elastic restoring force produced by the first elastic element 217 is opposite to the direction in which the process cartridge is disassembled, and the elastic restoring force produced by the first elastic element 217 acts on the slider 216 , so that the intermediate power transmission part 213 is deflected, as shown in Figure 12b, at the same time, the restoring force of the elastic element makes the slider 216 slide in the slide rail 2151 in the opposite direction of the removal direction of the process cartridge, and then through the intermediate power transmission When the component is deflected, it drives the rotary power receiving component 214 to retract along the opposite direction of the X direction (that is, the X' direction in the figure), and disengages from the rotary force driving head 11, and the force F gradually weakens or even disappears; continue to disassemble the process cartridge , the process cartridge is completely out of contact with the electronic imaging device, as shown in Figure 12c.

Through the implementation of this embodiment, the process cartridge can be installed in the process of the electronic imaging device without interference with the rotational force driving head; In the process that the inboard side of device keeps contacting, the rotational power receiving part 214 does not move relative to the mounting direction of the process cartridge with respect to the rotational force driving head 11; Relative movement occurs on the machine, and it engages or disengages with it, so that the process box can be installed smoothly.
