Description
【Technical field】
The present invention relates to the drive technology in imaging device, more particularly to a kind of transmission adjusting apparatus, handle box and imaging
Equipment.
【Background technology】
In general, in known process cartridge system, electrophotographic photosensitive member in imaging device and it is applied to it
Processing unit is integrated into box, which can be removably installed in image forming apparatus body；Such as laser printer, duplicate
In the electrophotographic image formings such as machine, facsimile machine, a handle box is typically provided with, which can be from electrophotographic image forming
In take apart, in order to which user can safeguard the device in process cartridge system, help to improve operability.
Existing handle box has following a few classes：One kind is photosensitive drums and developing apparatus, charging unit and cleaning device composition
Integral box；The another kind of split box for being photosensitive drums and charging unit is assembled together, or photosensitive drums and developing apparatus assembling
Split box together；Wherein, developing apparatus includes main body, transmission side, conductive side and memory unit package.
No matter which kind of integration mode, as long as box in have rotating processing component is needed in imaging process, be required for from
Electrophotographic image forming receives driving force, with driving processing component rotation.
A kind of existing actuator designs for universal joint, and one end is arranged in a cylindrical element of handle box end, the other end
Prominent to outside Delevoping cartridge, for being engaged with the drive shaft in electrophotographic image forming, universal joint can be direct after receiving driving force
Drive photosensitive drums or developer roll rotation.But this universal joint drive part easily comes off out of cylindrical element, so as to can not stably pass
Driving force is passed, and the cost of the driving force receiving part of this class formation is higher.
Also the driving force receiving unit for having the handle box that some producers produce to use mechanical assistance swing arm structure, is being handled
During capsule/taking-up by axial stretching realize driving force receiving unit and host driven head engage and disengaging；Or
Swing rod is promoted using host door closure, makes driving force receiving unit axially retractable to realize driving force receiving unit and host driven
The engagement and disengaging of head；Also the handle box of some producers production is loaded or taken out using strength mode and causes driving force component
Engaged with machine driving force component with departing from effect；The power that also many producer's uses can be swung receives pawl mode so that
Reach the effect engaged with departing between imaging device driving part and handle box power receiving part.
As shown in Figure 1 to Figure 3, assist to promote the mode of swing rod to depend on using swing rod auxiliary telescopic mode or host door closure
The structure of machine, compatibility is bad, and there is the problem of machine is not in place or taking-up is difficult, when being broken away from automatically such as machine
Time, auxiliary door closure or manual mode can not realize taking-up and the disengaging process of the driving force receiving portion part of axial stretching；
As shown in Figures 4 to 7, using the handle box for loading or taking out mode by force, there are some angles when falling machine to be transferred to
When driving part the problems such as not engaged with host driven head and causing to skid, taking-up when, needs larger artificial dynamics to take
Go out, or even stuck phenomenon occur.
As shown in Fig. 8 to Figure 14, the power that also having many producer's uses can swing receives pawl mode, although it is larger
State is blocked when solving taking-up in orientation, but also exists in some angle and takes out difficult phenomenon.
Moreover, either assist to promote the mode of swing rod, or strength using swing rod auxiliary telescopic mode or host door closure
The handle box of the mode torn open the either mode of rocking jaw is created, during handle box is split out, imaging device driving head will
Be in contact with the driving claw of driving force receiving unit, if position is incorrect, it may appear that the driving claw of driving force receiving part with
The problems such as engagement of imaging device driving head is blocked, i.e., handle box takes out the problem of easily interfering from image processing system.
