装置。 In a duplex paper feeding device of a copying machine that can temporarily store transfer paper with a copy formed on one side, and sequentially refeed the stored transfer paper from the lower side to obtain double-sided copies and composite copies. , Changed the contact surface of the reverse roller of the separation mechanism consisting of a feed roller and a reverse roller, which is linked to the switching operation of the stopper and pressure plate between stacking and refeeding transfer paper, to a new surface. The rotation of the reverse roller due to the change in the contact surface is prevented from being transmitted to the pick-up roller stopped at a predetermined position by a one-way clutch arranged on each axis of the feed roller and the pick-up roller. A duplex paper feeder for copying machines.
