See Fig. 3, control gear 30 is mounted to the side of box body 10, comprise the first flexible member 31, pushing block 32 and lever 33, pushing block 32 is contained in the accommodation section 12 of box body 10, and can slide relative to box body 10, there is glide direction X, be provided with stopper slot 32a, first flexible member erection column 32b, compression face 32c and stroke groove 32d, compression face 32c is set to circular arc for receiving the extruding force of image processing system door body, box body 10 is also provided with covering 34, covering 34 is provided with restriction protrusion 34a, restriction protrusion 34a coordinates with stopper slot 32a in case thrust block 32 comes off from accommodation section 12, the first flexible member reference column 11 that first flexible member 31 one end connects on the first flexible member erection column 32b other end connection box body thinks that pushing block provides precompression F, stroke groove 32d is in tilted layout relative to glide direction X, i.e. stroke groove 32d and glide direction X both not parallel also out of plumb, lever 33 is provided with the fulcrum hole 33c coordinated with pivot pole 13 on box body 10, lever 33 can rotate around pivot pole 33, lever 33 with fulcrum hole 33c for boundary, one end be provided with the slide post 33a that coordinates with stroke groove 32d and, the other end is provided with and pushes away inclined-plane 33e with drive division 27 by pushing away urgent that inclined-plane 21a coordinates and dodge the relief portion 33d of support column 14, slide post 33a is mounted in stroke groove 32d, and can slide between the initial position C and final position Z of stroke groove 32d by stroke groove 32d thrust, thus drive lever 33 to rotate around pivot pole 13, after lever 33 installs, compel to push away inclined-plane 33e, relative to axial direction Y, there is difference in height, compel to push away applying urgent thrust F2(when inclined-plane 33e rotates and participate in Fig. 7) compeled to push away drive division 27 along the inside indentation of Y-direction to pushing away inclined-plane 21a, thus drive power reception portion 24 to along the inside indentation of Y-direction.

In the present embodiment, lever 33 is arranged fulcrum hole 33c, box body 10 is arranged pivot pole 13, lever 33 rotates around pivot pole 13, and it can also be set to lever 33 arranges pivot pole, and box body 10 arranges fulcrum hole, and lever 33 rotates around fulcrum hole.In the present embodiment, stroke groove 32d is arranged on pushing block 32, and slide post 33a is arranged on lever 33, and it can also be set to stroke groove and be arranged on lever 33, and slide post is arranged on pushing block 32.

In the present embodiment, the first flexible member 31, second flexible member 22 is Compress Spring, and it can also be other elastic components such as elastic caoutchouc, elastic steel sheet.

The course of work of the utility model handle box is described below in conjunction with accompanying drawing 6-7.

When handle box does not work, pushing block 32 is by the precompression F of the first flexible member 31, pushing block 32 moves towards X-direction under the effect of precompression F, thus make slide post 33a be in initial position C in stroke groove 32d, when slide post 33a is in initial position C, lever 33 is rotated counterclockwise, now, lever 33 urgent pushes away inclined-plane 33e and applies to compel thrust F2 with what compel to push away drive division 27 and pushed away inclined-plane 21a, compel the restoring force F3 that thrust F2 overcomes the second flexible member, thus drive the power reception portion 24 inside indentation of Y-direction vertically by drive division 27, now power reception portion 24 is in indentation state, when being mounted to image processing system, can not interfere with machine driving head 100.

When handle box is mounted to image processing system, close the door body of image processing system, door body applies the compression face 32c of extruding force F1 to pushing block 32, extruding force F1 overcomes the precompression F of the first flexible member, pushing block 32 moves towards the opposite direction of X-direction, the slide post 33a being positioned at pushing block 32 stroke 32d groove slides into final position Z from initial position C, now, lever 33 rotates clockwise around pivot pole 13, lever 33 is compeled push away inclined-plane 33e to push away by pushing away the urgent of inclined-plane 21a by rotating slowly to remove, compel thrust F2 slowly to reduce, under the restoring force F3 effect of the second flexible member, reset is stretched out towards the opposite direction of Y-direction by power reception portion, now the power reception mouth 24e in power reception portion 24 engages with machine driving head 100, power reception mouth 24e receives the driving force of machine driving head 100, thus drive handle box normally to work.

When the complete needs of handle box work take out from image processing system, open the door body of image processing system, door body stops applying extruding force F1 to pushing block 32, now under the effect of the first flexible member 31 precompression F, pushing block 32 moves towards X-direction, thus make slide post 33a move to initial position C from final position Z, slide post 33a slides and lever 33 is rotated counterclockwise, now, lever 33 urgent pushes away inclined-plane 33e and applies to compel thrust F2 with what compel to push away drive division 27 and pushed away inclined-plane 21a, compel the restoring force F3 that thrust F2 overcomes the second flexible member, thus drive the power reception portion 24 inside indentation of Y-direction vertically by drive division 27, now power reception portion 24 is in indentation state

Power reception mouth 24e in power reception portion 24 departs from machine driving head 100 and engages, the taking-up handle box that can not interfere.

The utility model drive assembly of photosensitive drum 20 is provided separately due to drive division 27 and power reception portion 24, when compeling to push away with lever, the rotation in power reception portion 24 can not be subject to the impact compeling to push away effect, effectively avoid drive division and power reception portion and be set to one, when power reception portion rotates, lever and drive division compel to push away, and produce frictional influence power transmission with the power reception portion rotated.

This use novel process box is by being set to two parts by control gear, pushing block 32 and lever 33, by the extruding of machine door, the slip of pushing block 32 is converted into the rotary motion of lever 33, thus control the flexible of drive assembly of photosensitive drum 20, the flexible triggering of drive assembly of photosensitive drum 20 is from the extruding of image processing system door body, this trigger action utilizes client's this essential action of switch machines when using handle box just can realize, operating in addition without the need to client, meet the use habit of client, and the accurate handle box of this control can not produce interference in installation and removal process.

Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its in instructions still can be modified to the technical scheme described in foregoing embodiments, or equivalent replacement is carried out to wherein portion of techniques feature, and these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
