PURPOSE:To perform the double face electrophotographic copying where failures of resupply are prevented, by stacking up transfer papers, whose one face are already copied onto, while shifting their front ends and supplying again these transfer paper in order from the first transfer paper to copy on area faces. CONSTITUTION:A transfer paper P-1 whose one face is copied onto is fed onto a resupply tray and is fed downward on the tray by an elastic roll until the front end strikes a stopper 50. When a next transfer paper P-2 comes, the preceding transfer paper P-1 is fed by a pair of rolls 51 and 52, and the stopper 50 is displaced upward. Next, the stopper 50 is allowed to fall, and the next transfer paper P-2 strikes the stopper, and simultaneously, a pair of rolls 51 and 52 are stopped. This operation is repeated to pile up transfer papers while shifting their front ends. This pile of transfer papers is held between a large roll and a belt turning body and is carried to a prescribed position. The top transfer paper whose front end is in the frontmost is supplied again by a resupply roll brought into contact with the upper face of the pile. Next, the pile is advanced slightly to supply the next tranfer paper. |
