Abstract
The invention relates to a powdered carbon box in an electrophotographic imaging device, comprising a developing unit and a photoreceptor unit which are installed together in a detachable way. The developing unit at least comprises a developing roller, and the photoreceptor unit at least comprises a photosensive drum; and the developing roller and the photosensitive drum are matched so as to lead the developing roller to be capable of providing powdered carbon to an electro-static latent image on the photosensitive drum effectively, thus froming a developing image. The powdered carbon box further comprises an elastic part and an elastic bracket which is connected with the developing unit or the photosensitive unit in a detachable way, wherein the free end of the elastic part is connected with and forcibly pushes the photosensitive unit or the developing unit so as to lead the developing roller to close up the photosensitive drum.
Description
Technical field
The present invention relates to a kind of cartridge in the electrophotographic imaging forming apparatus.
Background technology
Electrophotographic imaging forming apparatus; The cartridge of laser printer particularly; It is mainly combined with certain connected mode by a developing cell and a photoreceptor unit; Developing cell mainly is made up of toner, stirrer, developer roll and powder feeding roller etc., and the photoreceptor unit mainly is made up of photosensitive drums, charging roller and waste powder hopper.Photosensitive drums is exposed in the laser, and to form electrostatic latent image above that, developer roll provides carbon dust to photosensitive drums, to form the image corresponding with electrostatic latent image.Cartridge adopts certain connected mode that developing cell closely is connected with the photoreceptor unit, thereby developer roll and the photosensitive drums in the photoreceptor unit in the developing cell are closely cooperated.
Cooperation between developer roll and the photosensitive drums is a ring important in the cartridge structure.For guaranteeing position relation between the two, traditional cartridge adopts three kinds of frame modes substantially:
First kind of frame mode: developing cell adopts connecting pin to be connected with the photoreceptor unit; On developing cell (or photoreceptor unit), be provided with stage clip; Stage clip is arranged on the opposite end that developing cell (or photoreceptor unit) is gone up developer roll (or photosensitive drums), and connecting pin is arranged between stage clip and the developer roll (or photosensitive drums), and stage clip is pressed and pushed away photoreceptor unit (or developing cell); With the connecting pin is rotating shaft, and developer roll and the photosensitive drums on the photoreceptor unit on the developing cell are closely cooperated.
Second kind of frame mode: developing cell both sides front end is provided with guidepost, and relevant position, photoreceptor unit is provided with guide rail, guidepost can on the guide rail on the photosensitive unit axis direction of photosensitive drums slide; Rear end, developing cell both sides is provided with bail, and relevant position, photoreceptor unit is provided with hole clipping, and bail is installed on the hole clipping, and hole clipping is bigger, and bail can slide in hole clipping; Developing cell and photosensitive unit are provided with extension spring, and extension spring one end is held developing cell, and the other end is held the photoreceptor unit, extension spring tension developing cell and photosensitive unit, thus developer roll and the photosensitive drums on the photoreceptor unit on the developing cell are closely cooperated.
The third frame mode: the cartridge both sides are provided with end cap; End cap is provided with pilot hole; The cartridge end covers at two sides connects as one developing cell and photoreceptor unit; Pilot hole on the end cap is to the photosensitive drums on developer roll on the developing cell and photoreceptor unit location, thereby developer roll and the photosensitive drums on the photoreceptor unit on the developing cell are closely cooperated.
The cartridge of making according to above-mentioned technology exists following not enough:
Adopt the cartridge of first kind of frame mode, though stable performance, loading and unloading are complicated;
Adopt the cartridge of second kind of frame mode, the same complicated deficiency of loading and unloading that exists, for example: when dress developing cell and photoreceptor unit, both sides, photoreceptor unit need be out of shape and could the bail of developing cell be put in the hole clipping; The developing cell leading edge portion abrades photosensitive drums easily, needs speciality tool in narrow space, to operate during the dress extension spring.
Adopt the cartridge of the third frame mode, dimensional requirement is accurate, has brought a lot of difficulties to the manufacturing, has also strengthened production cost simultaneously.
Summary of the invention
The present invention provides a kind of cartridge, and is complicated to solve existing cartridge developing cell and photoreceptor unit loading and unloading, the technical matters that the production dimension precision requirement is high.
In order to solve above technical matters, the technical scheme that the present invention takes is:
A kind of cartridge; Comprise developing cell and photoreceptor unit, said developing cell and said photoreceptor unit removably connect, and said developing cell includes a developer roll at least; Said photoreceptor unit includes a photosensitive drums at least; Said developer roll cooperates crimping with photosensitive drums, it is characterized in that, also comprises elastomeric element and is arranged at the elastic support on said developing cell or the said photoreceptor unit; Said elastic support is provided with the web member that removably connects with said developing cell or photoreceptor unit; Said developing cell or photoreceptor unit are provided with the connected piece that is complementary with said web member, and said elastomeric element is arranged between said developing cell and the elastic support, perhaps is arranged between said photoreceptor unit and the elastic support, and said developer roll and said photosensitive drums are drawn close.
Said elastic support has two, is separately positioned on the two ends of said developing cell or said photoreceptor unit.
Said elastomeric element is arranged on said developing cell, photoreceptor unit or the elastic support.
Said elastomeric element is spring or one group of magnetic element.
Said one group of magnetic element is separately positioned on said developing cell and the elastic support, perhaps is arranged on said photoreceptor unit and the elastic support.
Said web member is a hasp, and said connected piece is for taking the hole.
Said web member is for taking the hole, and said connected piece is a hasp.
Said hasp comprises flank hasp and top hasp, and the said hole of taking comprises that flank takes Kong Heding and take the hole.
Said connected piece is arranged on the said photoreceptor unit.
The both sides of said developing cell are respectively equipped with two frong guide columns and two BB1s; The both sides of said photoreceptor unit are respectively arranged with and described two frong guide columns and two two fromer rails and two rear rails that BB1 is complementary; Said two frong guide columns are positioned at two fromer rails, and said two BB1s are positioned at two rear rails.
After having adopted technique scheme, only need to compel to push away developing cell or photoreceptor unit through the elastomeric element that is arranged on the elastic support, stage clip is regulated elastic force just can guarantee the position relation between developer roll and photosensitive drums.Stage clip more is prone to install than extension spring simultaneously, and effectiveness is more lasting, and the production accuracy requirement is not high, has solved existing cartridge developing cell and photoreceptor unit loading and unloading complicacy, the technical matters that the production dimension precision requirement is high.Convenient installation and operation of the present invention, performance are more stable, reliable.
