Description
Technical field
The present invention relates to electrophotographic image forming printing technique field, specifically, being to be related to one kind to be removably mounted on
The installation method and method for dismounting of handle box, the handle box on electrophotographic image forming and the electronics with the handle box
Photograph imaging device.
Background technology
Electrophotographic image forming is a kind of image to be formed on print media such as paper using electrofax principle
Equipment including duplicator, printer, facsimile machine, all-in-one machine etc., generally includes host and the place being removably installed in host
Manage box.Wherein, rotating element is provided on handle box and receives the rotary force biography for the rotary driving force that the hosts such as printer provide
Component is passed, rotating element includes at least one kind in developing element, photosensitive drums, charge member, and handle box is installed to host,
Rotation force transfer unit matches the rotary force for merging and receiving driving mechanism and providing with the driving mechanism of host, and then drives rotating element
Rotation.
A kind of existing handle box tool there are two driving force receiving portion part, one be arranged on photosensitive drums axial end it is photosensitive
Drum driving head, another is the developer roll driving head for the axial end for being arranged on developer roll.Developer roll driving head is mainly by multiple groups
Part forms, and the deviation in driving head axle center and developer roll axle center is realized by cross chute coupling structure.Moreover, just place
When reason box is put into printer, the limitation of handle box subject printer internal structure, handle box driving head is passed less than printer
Dynamic head, when printer lid is closed, the lid of printer is lifted handle box in the anti-drive end of handle box, makes handle box
Two driving force receiving portion parts respectively with two driving heads of printer coordinate.
It installs after handle box since developer roll driving head has been engaged with the driving head on printer, and handles every time in this way
Box is moved up perpendicular to the direction of developer roll driving head, be may result in the part that developing drive head is engaged with driving head and is generated
Abrasion.Since engaging portion area is smaller on developer roll driving head, even if setting cross chute coupling structure can mitigate
The abrasion of the engaging portion, but it is difficult to avoid that whole abrasion, which is,.
Invention content
The main object of the present invention, which is to provide one kind, can avoid developer roll driving head wear problem during installing, improve and beat
The handle box of printing matter.
It is a further object of the present invention to provide a kind of electrophotographic image formings with above-mentioned handle box.
Another object of the present invention is to provide a kind of installation method of above-mentioned handle box.
The a further object of the present invention is to provide a kind of method for dismounting of above-mentioned handle box.
To realize above-mentioned main purpose, the present invention provides a kind of handle box, which includes box body and can be around rotation
Axis is rotatably supported on photosensitive drums and developer roll between the end walls of box body, and an axial end of photosensitive drums is provided with photosensitive
Drum driving head, an axial end of developer roll are provided with developer roll driving head, and photosensitive drum driving head and developer roll driving head are located at
The homonymy of box body；Developer roll driving head includes coupling component, driving force receives head and axial return unit, and the inside of coupling component is opened
Equipped with accommodating chamber, driving force receives head and axial return unit is respectively positioned in accommodating chamber, and the axial end that driving force receives head is calm
Chamber of receiving stretches out, and driving force receives head and can be moved along the axial reciprocating of coupling component, and axial return unit is elastic component, and the of elastic component
One end is connected to driving force and receives on head, and the second end of elastic component is connected on the bottom wall of accommodating chamber；Handle box, which further includes, compels to push away
Mechanism compels pushing mechanism and is hinged on box body by hinge shaft, compels pushing mechanism and includes compression zone and push part, compression zone and humping section
Not Wei Yu hinge shaft both sides, compression zone is set on photosensitive drum driving head and positioned at box portion outside, and push part is received with driving force
Head connects and driving force is pushed to receive head and moved to far from box body side.
By said program as it can be seen that handle box is in electrophotographic image forming is installed to and closes before door closure, driving force
It receives head not contact with the second driving head, after door closure is closed, the first driving head of electrophotographic image forming stretches out and to urgent
The compression zone of pushing mechanism applies pressure, and urgent pushing mechanism is forced to be rotated around hinge shaft, and push part pushes driving force and receives head outward, so as to
Driving force is made to receive head to stretch out and engage with the second driving head of electrophotographic image forming, this kind of structure can ensure to close in door closure
During closing, when being moved up perpendicular to the direction of developer roll driving head, driving force receives head and will not be passed with second handle box
Dynamic head contact generates interference, and developing drive head will not be caused to lead to the problem of abrasion.
One Preferable scheme is that, developer roll driving head further includes position-limit mechanism, and position-limit mechanism limitation driving force receives head
