As shown in Figure 8 and Figure 9, in the present embodiment, the first power receiving portion 602a is arranged on movable part 602, and the second power is held
It is arranged on by portion 603a in separation unit 603, movable part 602 and the split of separation unit 603 are set, and mounting post is provided with framework 2
2c1, movable part 602 and separation unit 603 are coaxial to be arranged on mounting post 2c1, and movable part 602 is configured to that with separation unit 603
This is freely rotatable.It is additionally provided with framework 2 on First elastic component connecting portion 2c2, movable part 602 and is provided with the second elastic structure
Part connecting portion 602b, one end of elastic component 10 is connected to the First elastic component connecting portion 2c2 other ends and connected with second elastic component
Socket part 602b connections, the limiting section that movable part 602 can rotate under the elastic force of elastic component 10 and be arranged on framework 2
2c3 is limited and stopped at limiting section 2c3.Because movable part 602 is co-axially mounted with separation unit 603, movable part 602 is set into ratio
Separation unit 603 can prevent the elastic component 10 for connecting movable part 602 and framework 2 to separation unit in the inner side closer to framework 2
603 compressing and cause separation unit 603 rotate the problem of resistance is excessive.Protecting cover 501 is provided with to the side of framework 2 above
First screens 501a and the second screens 501b, the first screens 501a and the second screens 501b is used for the rotation for limiting separation unit 603
Scope, the first screens 501a setting is to prevent separation unit 603 from being rotated excessively without can be with the to close to power reception portion 4
Two power applying unit 63b are engaged, and the second screens 501b setting is in order to when the second power applying unit 63b pulls separation unit 603 to rotate
When, separation unit 603 drives developing cell to rotate by being stopped by the second screens 501b.Compel push position when developing cell is in
When, the first power applying unit 63a promotes movable part 602 to overcome the elastic force of elastic component 10 to rotate, and developing cell is in elastic component
Developer roll is caused to contact photosensitive drums with certain pressure under 10 elastic force, after the completion of printing, the second power applying unit 63b pulls the
Two power receiving portion 603a simultaneously cause separation unit 603 to rotate and finally drive developing cell to be in point that developer roll is separated with photosensitive drums
Every position, during separation developer roll with photosensitive drums, the second power applying unit 63b does not contact the movable part 60 all the time.From
The rotation axis direction of developer roll 3 sees that separation unit 603 and at least a portion of movable part 602 are overlapping with overall compact setting point
From portion 603 and movable part 602.In order to prevent separation unit 603 and movable part 602 from departing from from mounting post 2c1, along developer roll 3
Rotation axis direction sees that protecting cover 501 covers at least a portion of movable part 602 or separation unit 603.
In the present embodiment, elastic component 10 is preferred to use the structure of extension spring, selectable to use the torsion spring of stage clip
Etc. other structures, to show using the elastic force of the elastic components such as extension spring, stage clip and torsion spring by appropriate structure design

It can preferably cause structure compacter on mounting post 2c1 and reduce the volume of developing cell, still, movably
Portion 602 and separation unit 603, which are arranged in the different mounting posts of framework 2, can similarly reach the technique effect of the present embodiment.
Separation unit 603 is arranged to be freely rotatable mode and causes that the power applying unit 63b of separation unit 603 and second can be with as the presently preferred embodiments
More flexibly coordinate and be difficult to be disengaged from, because separation unit 603 need not provide the pressure that developer roll contacts photosensitive drums,
Separation unit 603 can be arranged to non-movable, specifically by separation unit 603 by the first screens 501a and the second screens 501b
Limitation and it is immovable, or separation unit 603 and framework 2 are integrally formed and separation unit 603 is fixed on framework equally can be with
Reach separation developer roll and the technique effect of photosensitive drums.
As described in Figure 10, as the variant embodiment of the present embodiment by the first power receiving portion 604a and the second power receiving portion
604b is arranged on same movable part 604, and movable part 604 is installed on mounting post 2d on the frame 2 and rotatable, extension spring 11
The other end of one end connection framework 2 connects movable part 604, when developing cell to show in urgent push position using the elastic force of extension spring 11
Shadow roller contacts photosensitive drums with certain pressure.The volume of developing cell further can be done small.
More than of the present utility model in each specific embodiment, movable part preferably is all moved with direction of rotation, but this area
It will be appreciated by the skilled person that movable part not only could cause elastic component deformation and reach and compel to push away development by rotary moving
Roller contacts the technique effect of photosensitive drums with certain pressure, and movable part can similarly cause elastic component deformation by slip and reach
To the technique effect for compeling to push away developer roll and being contacted with certain pressure photosensitive drums.In various embodiments above, the ordinary skill people of this area
Member it should be appreciated that framework should include protecting cover, the component such as movable part, elastic component and separation unit can with installation frame comprising protecting cover
On any one.
Developing cell and photosensitive unit are preferably to be provided separately in the present embodiment, selectable, developing cell and photosensitive list
The handle box form that member can also be made of one, developing cell in the handle box is rotated around photosensitive unit and can reach this practicality
The technique effect in each embodiment in new.
Although the utility model has been described with reference to specific embodiments, do not having for those skilled in the art
Various modifications can be done under conditions of scope of the present utility model.
