Embodiment mono-

As shown in Figure 6 to 8, photo-sensitive cell also comprises, is arranged in the middle of photosensitive drum gear 21Fixed head 24 and elastic transmission actuation mechanism, movable transmission mechanism comprises guide pillar 22 and spring 23. SenseLight drum gear 21 comprises support column 211 and hole 210. Its mesopore 210 is through hole, and comprises step surface.

Guide pillar 22 comprises upper part, lower part and mid portion, the wherein diameter of mid portionBe greater than upper part and lower part. The upper part of guide pillar 22 can be through the hole of photosensitive drum gear 21210, mid portion and step surface butt, lower part is connected with spring 23, another of spring 23End is connected with fixed head 24.

On fixed head 24, be provided with spacing hole 241, the support column 211 on photosensitive drum gear 21 and limitHole 241, position connects.

As shown in Figure 5, power transmission shaft 11 comprises claw 112, axle 111 and base 113, and axle 111 connectsConnect claw 112 and base 113, on base 113, also arrange porose 114. Claw 112 for becomeThe driving head of picture equipment connects, and accepts driving force. Hole on base 113 is used for and movable driverStructure connects, and transmits the driving force of accepting from imaging device to photosensitive drums 20.

In the time that the lid of imaging device is not closed, under the effect of the second flexible member 14, power transmission shaft11 are offset under the effect of power F1, thereby guide pillar 22 is departed from from hole 114; ClosingAfter lid, lid has applied power F to slide block, and power F is greater than power F1, makes power transmission shaft 11 get back to baseThe position that this is coaxial with photosensitive drums L, power transmission shaft 11 drives and rotates with imaging device, makes guide pillar 22In the effect of spring 23 next time in the hole 114 of base 113, thereby drive photosensitive drums 20 1 to run upMoving.

Embodiment bis-

As shown in Fig. 9 to Figure 13, the present embodiment is with the difference of implementing one: movable biographyThe structure of actuation mechanism and embodiment mono-are different.

Particularly, in the present embodiment, movable transmission mechanism comprises bullet piece 26 and pin 27. Photosensitive drumsGear 21 comprises support column 211 and opening 212, and its split shed 212 comprises through hole 214 and depression213。
