<p>PURPOSE:To surely convey copying paper where curl is removed to a loading part by constituting a curl correcting device of one long curl removing correcting roller and plural curl correcting rollers which press-contact to the peripheral surface of the curl removing roller, are overlapped one another in the parts of their peripheral surface parts and arranged in zigzag one another in the direction of an axial line. CONSTITUTION:The automatic both-surface device ADD of an electro photographic copying machine is made to posses the function of both-surface copying and superposed copying for copying paper 2, and the paper 2 is conveyed to a photosensitive drum 4 by a resist roller 3. A guiding plate 11, paper ejecting rollers 12 and 13 which are provided in the proper spots of the plate 11 and the curl correcting device 14 are arranged in the ADD supply part 8. The device 14 is constituted of one long curl correcting roller 71 which is pivoted to the frame of the supply part 8 and the plural curl correcting rollers 72 and 73 which respectively press-contact to the roller 71 and are divided into small parts and the roller 72 and 73 are arranged in a state where the outer peripheral parts of the rollers 72 and 73 are overlapped each other.</p> |
