Description
Technical field
The utility model relates to a kind of photosensitive element box, and this photosensitive element box is used for the image forming apparatus such as the laser printer of electro photography.
Background technology
The image forming apparatus of electro photography such as laser printer are a kind of electrofax principles of utilizing, and through overcharging, exposure is developed at least, transfer printing, and fixing forms the equipment that forms image on medium such as the paper at image.
In charging process,, utilize as the corona discharge mode evenly predetermined electric charge is filled with in the surface of photo-sensitive cell such as photosensitive drums by charging device; In exposure, the photosensitive member surface of filling even predetermined charge with is carried out optionally exposure, by the place of exposure, because the light sensitive characteristic of photo-sensitive cell, resistance descends, so by the electric charge ground connection cancellation in the localities of exposure, promptly after the exposure, photosensitive member surface formation one forms the electrostatic latent image that distribution characterized by electric charge of image corresponding to institute's desire; At developing process, by developing parts, developer that is used to form visual image such as carbon dust, the effect of mating reaction power such as electric field force is delivered on the electrostatic latent image of photosensitive member surface, and it is visual to make that above-mentioned electrostatic latent image obtains; In transfer process,, as transfer roll the developer on the photosensitive member surface electrostatic latent image is transferred to image and form on medium such as the paper by the transfer printing assembly; At fixing, the developer of transferring on the image formation medium is secured on the image formation medium by the photographic fixing assembly.
Photosensitive element box is removably installed in image forming apparatus, holds the thoughts optical element in it, and the cleaning brush that is used to clean photosensitive member surface.Photosensitive element box can also further include the charging devices such as corona wire that photo-sensitive cell is charged.In image forming course, need that image is formed medium such as paper is passed in the transfer printing assembly, be used to make developer such as carbon dust on the electrostatic latent image of photosensitive member surface to transfer to paper.
Prior art provides a kind of like this method of transmitting paper, as shown in Figure 1, a pair of air roll is arranged, wherein the first air roll 12a is mounted on the box body bottom of photosensitive element box 1, the first air roll 12a is a cylindrical steel axle, and the second air roll 12b is mounted in the image forming apparatus (not shown).As shown in Figure 1, when photosensitive element box 1 is installed in the image forming apparatus, the first air roll 12a on photosensitive element box 1 bottom surface faces the second air roll 12b in the image forming apparatus, two rollers of the first air roll 12a and the second air roll 12b contact and form normal pressure, wherein rotate under the motor (not shown) effect of the second air roll 12b in image forming apparatus, thereby driving the first air roll 12a rotates synchronously, with this paper P is sent to transfer printing assembly place, be photo-sensitive cell 10 and transfer roll 11 places, the carbon dust on the electrostatic latent image on photo-sensitive cell 10 surfaces is transferred on the paper.
In this paper transmission mechanism, need the first air roll 12a is installed on the box body of photosensitive element box 1, mounting means such as Fig. 2 of the first air roll 12a of prior art, Fig. 3, shown in Figure 4, the first air roll 12a is fixed on the box body of photosensitive element box 1 by two end portion supports, Fig. 3 is the installation original state figure of the first air roll 12a, wherein the two ends of the first air roll 12a are respectively arranged with circular hole 13, the box body of photosensitive element box 1 is provided with through hole 14, the end of tommy 15 is provided with projection 15a, at first the first air roll 12a is scheduled to be positioned at position shown in Figure 3, then tommy 15 is inserted in the through hole 14 along direction shown in the arrow A, as shown in Figure 4, in the time of in tommy 15 places through hole 14, its tip protrusion 15a inserts in the circular hole 13 of the first air roll 12a, the two ends of the first air roll 12a all adopt this to install and fix mode, because the external diameter of projection 15a is slightly less than the internal diameter of circular hole 13, thereby the first air roll 12a rotatably is supported and fixed on the box body bottom of photosensitive element box 1, cooperates the transmission paper with this with the second air roll 12b in the image forming apparatus.
If the first air roll 12a adopts the above-mentioned mode that installs and fixes, if the manufacturing accuracy or the axis hole quality of fit defect of insufficient of parts such as tommy 15 and positioning through hole 13 occur, cause the right alignment that operates between parts not high easily, the running accuracy of the wearing and tearing back first air roll 12a is lower under long-term rotary work, cause air roll paper feeding out of true that thereby the phenomenon of paperboard takes place, have a strong impact on the usability of product.
