Detailed description of the invention

Below, embodiment of the present utility model is illustrated.

Fig. 1 is the sectional view of image processing system of the present utility model.

As it is shown in figure 1, the image processing system 100 in present embodiment includes image forming part 10, possesses the supply unit 11 of pick-up roller 34, discharge portion 12 and image read-out 13.

Image read-out 13 arranges oriented original copy and launches the light source of light, is sent to image forming part 10 after becoming the signal of telecommunication after the imaged lens of reflection light of original copy reflection and optical image security.

Image forming part 10 possesses the Y (yellow) that configures side by side along transfer belt 15, M (magenta), these four groups of images of C (cyan), K (black) form station 16Y, 16M, 16C and 16K.Each image forms station 16Y, 16M, 16C and 16K around the photosensitive drums 17Y rotated along arrow a direction, 17M, 17C and 17K, possess Charging system 18Y, 18M, 18C and 18K of powering for photosensitive drums, electrostatic latent image in photosensitive drums is carried out developing unit 20Y, 20M, 20C and 20K of developing and photoreceptor photosensitive drums cleaner 21Y, 21M, 21C and 21K.

Exposure device 22 irradiating laser of image forming part 10, and on each photosensitive drums 17Y, 17M, 17C and 17K, form electrostatic latent image.

Support roller 27 and driven voller 28 supports transfer belt 15, make transfer belt 15 advance along arrow b direction.Primary transfer roller 23Y, 23M, 23C and 23K of being positioned at the developing unit inside transfer belt 15 will be formed in each photosensitive drums 17Y, the toner image of 17M, 17C and 17K is primarily transferred in transfer belt 15, and make toner image overlap in transfer belt 15.Each photoreceptor cleaner 21Y, 21M, 21C and 21K remain in the toner on photosensitive drums 17Y, 17M, 17C and 17K after removing primary transfer.

The secondary transfer roller 31 being on the position that transfer belt 15 is relative with supporting roller 27 is driven in transfer belt 15 and rotates along arrow c direction.Secondary transfer roller 31 using the toner image in transfer belt 15 together secondary transfer printing supply along transport path 36 from supply unit 11 as the medium 40 of record medium.

Transfer belt 15, image form station 16Y, 16M, 16C and 16K, laser explosure device 22, primary transfer roller 23Y, 23M, 23C and 23K and secondary transfer roller 31 and constitute image forming part.Image forming part 10 possesses fixing device 9, distributing roller to 37 along transport path 36 in the downstream of secondary transfer roller 31.

When starting to duplicate, image processing system 100 utilizes image forming part 10 to form toner image on medium 40, at fixing device 9 place, toner image is fixing after medium 40, and medium 40 is expelled to discharge portion 12.

Fig. 2 is the structural representation of erasing device in one embodiment of this utility model；Fig. 3 is the structural representation of cleaning part shown in Fig. 2；Fig. 4 is the perspective view of receiver shown in Fig. 2.

As in figure 2 it is shown, the mode of operation of erasing device 8, by selecting key to choose, after selecting colour killing pattern, being put into the medium 40 treating colour killing by supply unit 11, medium 40 here is that have employed can medium 40 after colour killing toner transferred image.Medium 40 enters scanner section 81 by transfer passage, and the lettering rate of medium 40 positive and negative of process is scanned identifying and storing by scanner section 81.Medium 40 after scanning enters thermal source portion 82, and the medium of process is applied predetermined temperature by heating roller and carries out colour killing by thermal source portion 82, and the medium 40 after colour killing enters cleaning part 83 and removes dirt further.The medium 40 that cleaning part 83 is discharged is again introduced into scanner section 81, this medium 40 is scanned identifying by scanner section 81 again, and the previous scan result of result Yu this medium 40 is compared, meeting predetermined standard time, this medium 40 is being delivered to the available pallet 841 in stowage portion 84；As do not met predetermined standard time, then this medium 40 is delivered to the discarded pallet 842 in stowage portion 84.

In colour killing process, whether scanner section 81 works, it is possible to selected by button.

As it is shown on figure 3, cleaning part 83 includes the clearer 831 that pair of parellel is arranged, medium 40 is passed through by the passage between two clearers 831.

Clearer 831 during work carries out rotation, the direction of rotation is contrary with the direct of travel of medium 40, and rotational velocity is more than the gait of march of medium 40, by the positive and negative surface of medium 40 is rubbed, can will be attached to the dirt removal on medium 40 surface, dirt here refers to except toner image, is immersed on medium 40, is difficult to the object from medium 40 surface removal.

Friction through clearer 831, it is possible to the dirt removal cannot will removed by colour killing on medium 40 so that medium 40 is when being again introduced into scanner section 81, it is possible to reduce the quantity of the discarded medium 40 caused except colour killing reason.

For improving the medium 40 stability when clearer 831 rubs, a pair conveying roller 833 can be respectively provided with at medium 40 approach axis of clearer 831 and medium 40 discharge direction, medium 40, when clearer 831 works, is stretched by conveying roller 833, avoids the cleaned roller 831 of medium 40 to be with partially simultaneously.

Circumferential surface at clearer 831 can also arrange hairbrush 8311, improves cleaning effect, avoids clearer 831 and conveying roller 833 mismate simultaneously, and affects the traveling of medium 40.

For collecting the dirt that cleaning part 83 is removed, in the side that clearer 831 is relative with medium 40, it is possible to arrange the receiver 832 collecting the foreign material adhered on hairbrush 8311.

As shown in Figure 4, the receiver 832 of present embodiment is the structure that one side is uncovered, it is uncovered relative with hairbrush 8311 direction of rotation, and it is positioned on the swing-around trajectory of hairbrush 8311, hairbrush 8311 is by cleaning on medium 40 and sticking to the dirt on hairbrush 8311, when encountering receiver 832, the side being contained box 832 scrapes and falls into receiver 832, thus preventing the hairbrush 8311 secondary pollution to medium 40.

For convenience of scraping dirt from hairbrush 8311, this receiver 832 contacts the sidewall front end of side with hairbrush 8311, spaced comb 8321 can be set, when hairbrush 8311 contacts with receiver 832, deviate from again after entering the space of comb 8321, under the dirt adhered on hairbrush 8311 is then blocked by comb 8321, this embodiment can improve the cleaning effect to hairbrush 8311.

Although the description of several embodiments of the present utility model, but these embodiments are intended only as example and propose, and are not intended to limit scope of the present utility model.These new embodiments, it is possible to be carried out in other various modes, in the scope without departing from the main idea of utility model, it is possible to carry out various omission, displacement, combination and change.These embodiments and its deformation are all contained in scope of the present utility model and main idea, and are contained in this utility model described in claims and in equivalency range.
