In the present embodiment, when the paper feeding roller 133 stops feeding paper, the paper feeding roller 133 rotates in a second direction B (as shown in fig. 20) opposite to the first direction. When the paper feeding roller 133 rotates in the second direction B, the first gear 1941 of the gear set 194 engages with the one-way bearing 1943 to rotate, the first gear 1941 drives the second gear 1942 to rotate, the second gear 1942 drives the cover member 193 to move by engaging with the rack portion 1931, and simultaneously stretches the elastic member 196, so that the cover member 193 closes the opening 1910 of the accommodating case 191.

Further, when the paper feeding roller 133 feeds the paper again, the paper feeding roller 133 rotates in the first direction a (as shown in fig. 21), the first gear 1941 of the gear train 194 is no longer restricted by the rotation in the second direction B engaged by the one-way bearing 1943, and thus the elastic member 196 is no longer stretched by the external force of the gear train 194. The elastic member 196 pulls one end of the cover member 193 again by an elastic restoring force, and at the same time, the rack portion 1931 of the cover member 193 rotates the gear set 194, wherein the first gear 1941 of the gear set 194 is not rotated by the paper feeding roller 133, but does not restrict the first gear 1941 of the gear set 194 from rotating in the same direction. The cover member 193 reopens the opening 1910 of the receiving pocket 191 and is not restricted by the rotation of the gear train 194.

To sum up, the application provides an image processing apparatus, can assemble in image processing apparatus's casing through clean subassembly, with dust (or dust etc.) on the clean subassembly clearance gyro wheel, also can dismantle the clean subassembly from image processing apparatus's casing, clean the back to the clean subassembly, can assemble the clean subassembly again and continue clean gyro wheel on image processing apparatus. The application can provide a dust holding subassembly in addition and set up in the casing to be located the below of cleaning member, be used for accepting dust or dust that the cleaning member scraped when contacting with the gyro wheel. The dust containing assembly can be matched with the cleaning piece to assemble and open the opening of the containing box for collecting dust, and the dust containing assembly can also seal the opening of the containing box through the disassembly of the cleaning piece to prevent the dust from flying. In addition, the dust containing assembly also has a mode of opening the containing box and closing the opening of the containing box through the paper feeding roller. The present application provides a dust holding assembly for collecting dust (or dust, etc.) and housing the dust (or dust, etc.).
