PURPOSE:To invert copying paper in a short copying paper passage by inverting the copying paper on the basis of the switch-back method and carrying the inverted copying paper from the back of intermediate copying paper receiving boards to a receiving board. CONSTITUTION:The 2nd movable guide plate 108 is arranged as the 2nd movable guide means between a copying paper inverting means 20 and the intermediate copying paper receiving boards 102, 102. The guide plate 108 is carried by a shaft 59 so as to be rotated between the upper position (shown by a solid line) and the lower position (shown by a virtual line). When the guide plate 108 is located on the upper position, the guide plate 108 guides the copying paper towards the 2nd intermediate copying paper receiving board 103, and at the lower position, guides the copying paper towards the 1st intermediate copying paper receiving board 102. When the copying paper carried to a switch- back guide part 109 is detected 111, a pair of rollers 110 are rotated in the reverse direction against the arrow and the copying paper is inverted at its advancing direction on the basis of the switch-back method and while being guided by the guide plate 108 located on the dotted position, carried to the 1st board 102 from its back. |
