Abstract
The invention relates to a photosensitive element driving mechanism. The driving mechanism comprises: a driving head for accepting driving force from an image forming device; a drum flange fixedly connected to the end part of the photosensitive element, driving the photosensitive element to rotate and having an annular end plane; and a conductive mechanism allowing the contact on the image forming device to be in electric connection with the aluminum base of the photosensitive element, wherein the conductive mechanism and the driving head are arranged on a same side; and the driving head can axially rotate relative to the flange. The driving mechanism occupies a small volume in the image forming device, and the axial rotation of the driving head relative to the flange at the image forming device starting moment makes the driving head have a buffer effect at the starting moment when the driving head and the flange provide rotation power for the photosensitive element, so the instant impact force of the driving head is substantially reduced, thereby the driving head is protected from damage.
Description
Technical field
The present invention relates to the handle box that a kind of image processing system is used, relate in particular in the handle box the photo-sensitive cell driving mechanism.
Background technology
The image processing system 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, evenly predetermined electric charge is filled with in the surface of photo-sensitive cell such as photosensitive drums through charging device; At exposure process; Photosensitive member surface to filling even predetermined charge with optionally makes public, and the place of being made public is because the sensitometric characteristic of photo-sensitive cell; Resistance descends; So the electric charge ground connection cancellation in the localities that is made public, 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, through 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,, transfer to image to the developer on the photosensitive member surface electrostatic latent image like transfer roll and form on medium such as the paper through transfer device; At fixing, be secured in the developer of transferring on the image formation medium on the image formation medium through fixing device.
Fig. 1 knows that by figure photo-sensitive cell is in exposure process for the synoptic diagram of photo-sensitive cell formation electrostatic latent image; Being excited light-struck charge transport layer CTL partly becomes conductor, is excited light-struck charge generating layer CGL part then to produce positive and negative charge, and the negative charge of positive charge and photosensitive drum surface neutralizes; Negative charge and the aluminium base positive charge that from the earth, comes produce neutralization; Photosensitive member surface has the voltage of picture and text parts to become near 0 volt, does not still keep original current potential and be excited light-struck part, at this moment; Photosensitive member surface has just produced potential difference (PD), produces electrostatic latent image.
Fig. 2 is the photo-sensitive cell driving mechanism synoptic diagram that prior art adopted; Know by figure; Photo-sensitive cell driving mechanism 1 comprises: be used to receive driving head 1 from the image processing system driving force, driving force passed to the bulging flange 2 of photo-sensitive cell 10; Driving head 1 and drum flange 2 integrated injection moldings, the photo-sensitive cell driving mechanism is fixedly connected with photo-sensitive cell 10 ends through the screens mode.Being used for conductive mechanism (not shown) that the conductive contact with the aluminium base and image processing system of photo-sensitive cell 10 is electrically connected is arranged on and the photo-sensitive cell driving mechanism other end of the photo-sensitive cell 10 of homonymy not; Be that photo-sensitive cell 10 has realized that through conductive mechanism circuit is connected with image processing system, for exposure process provides positive charge.
The shortcoming that prior art exists:
1. conductive mechanism and photo-sensitive cell driven unit are arranged on the not homonymy of photo-sensitive cell, have increased the usage space of image processing system, have promptly increased the volume of image processing system, cause the increase of production cost.
2. driving head is one-body molded for photo-sensitive cell provides rotary power with the drum flange, because startup moment of image processing system is very big to the instant impact of driving head, is easy to damage driving head, the instability that causes driving force to be transmitted.
Summary of the invention

The axial direction of said driving head is provided with through hole, and said contact one end is electrically connected with said conductor, and the other end is the free end that is positioned at said through hole.
Said conductive mechanism also comprises spring, and said spring is connected between said contact and the conductor, and said conductor is the conduction steel disc.
Said contact is screw form, and a wherein less end inserts in the said spring and is fixedly connected with said spring.
Said bulging flange comprises the cylinder that is arranged on a center hollow, and said contact and spring are positioned at said cylinder, and said cylinder stretches in the said through hole.
Said bulging flange also comprises two fixed legs, and said conduction steel disc is provided with two and presses the hole, and said conduction steel disc presses hole and said two fixed legs to be fixed on said bulging flange end through said two.
Also comprise torsion spring, said torsion spring set is connected on the said cylinder, and said torsion spring two ends are connected to said driving head respectively and rouse on the flange.
Said bulging flange comprises a pair of stop part that is arranged on radial symmetry on the inwall and the scalloped recess that is arranged on two radial symmetry distributions that the conductor side is installed, and said driving head is provided with the limiting section of two radial symmetry; Also be provided with the buckle of a pair of radial symmetry on the said driving head, said driving head passes said scalloped recess and said bulging flange end face clamping through said buckle, and said torsion spring two ends are connected to respectively on said stop part and the said buckle.
After having adopted technique scheme, because conductive mechanism and driving head are arranged on the same side, but driving head is with respect to drum flange axial rotation.Therefore; But the startup moment driving head of image processing system makes driving head have buffer action starting moment with respect to drum flange axial rotation when taking the less and driving head of volume in the image processing system and drum flange and be photo-sensitive cell rotary power being provided; Reduced the instant impact of driving head greatly; The protection driving head is not easy infringement, has solved existing photo-sensitive cell driving mechanism and has taken the big and easy damaged technical matters of driving head of volume in the image processing system.Secondly, because the axial direction of driving head is provided with through hole, contact one end is electrically connected with conductor, and the other end is the free end that is positioned at through hole.The split-type design of conductive mechanism and driving head, conductive mechanism can not receive the influence of image processing system to the instant impact of driving head generation, thereby the conduction that has guaranteed photo-sensitive cell is good.At last, because conductive mechanism also is provided with spring, can overcome conductive mechanism in the axial direction by size or cooperate the loose contact between caused and image processing system conductive contact, thereby the conduction that has guaranteed photo-sensitive cell is good.
