PURPOSE:To prevent the occurrence of static electricity and get rid of the wastefulness of movements by making at least one original-carrying means original-drivable in the opposite direction out of two independently drivable original-carring means. CONSTITUTION:A paper-feeding tray 39 is drawn out of a main body device 1, and an original is placed on the first, second original beds 44, 42 at the lower side of a contact-glass 14 and made to stop, and exposure processing is done. Original beds 44, 42 are independently driven. Sprockets 41c and 41b are driven through a chain 41d by a sprocket on a main motor side which is out of the drawing. A gear 41a also starts revolving and drive force is conveyed to a gear 40a, too, and a paper-feeding roller 40 starts the paperfeeding of the original. Since a spring is put between shafts for a separationroller 41, the roller 41 starts revolving after the spring has absorbed revolution and revolves in the direction contrary to the revolving direction of the paper-feeding roller 40. By this, friction between rollers and the copy is lessened, and the occurrence of static electricity is oppressed, and the wastefulness of movements is removed. |
