PURPOSE:To prevent jamming from taking place by allowing a push-up plate to be located at an upper position when a stopper, which is stopped at the afterward stop position, of a stack unit combined with a transfer unit, is moved forward by the stated distance in an electronicphotographic copying machine and the like. CONSTITUTION:A form which is transferred by an image holding unit 105, is piled up in a stack unit combined with a transfer unit by way of a conveyor belt 101, a flapper 6, a feed roller 76, and a conveyor path 19. And when a signal which indicates that a single side of the form has been copied, is outputted, a stopper 32 allows a bandle of forms to be forwarded by means of a wire 61. And the stopper 23 is suspended just before it comes in contact with a forward end stopper 33 while the bandle is placed on a push-up plate 32. Simultaneously, the push-up plate 32 is raised permitting the uppermost form to come in contact with the lower surface of a feed belt 35 with pressure. Then, the feed belt is intermittently rotated allowing the uppermost form to be reversed, and then, the form is forwarded into a place between the image holding unit 105 and a transfer print/separation pole 107 through an over-lap prevention roller 38, a guide plate 82, and a regist roller 104. |
