Abstract

PURPOSE:To prevent set-off of a both side sheet original by bringing a black colored member in contact with the rear surface. CONSTITUTION:The sheet originals on a paper feed tray 20 are pressed through an exposure window 23 and are fed successively onto a paper discharge tray 21 by a feed roller 22. The front side of the originals is projected onto a photosensitive drum by a mirror 18. When the copying on the front side is finished, the tray 21 is turned in a direction A by a motor to return the originals onto the tray 20 while turning them over. At this time, a pawl 29 turns in a direction B and is unlocked, then an original supporting body 27 turns from the broken line position to the solid line position, thereby preventing the falling of the originals. An original backup cylinder 35 is white and black (dark color can do as well) at every half period, and in the case of the original printed on both sides, the black colored surface contacts with the original, thereby preventing set-off.
