    • PURPOSE:To peel off reliably from an end part of stencil paper by eliminating defective peeling-off of the stencil paper, by a method wherein a pair of plate discharge peeling rollers are turned oppositely from each other in the direction putting the stencil paper between the nip parts of the rollers. CONSTITUTION:When a plate discharge motor 57 is turned, turning force is transmitted in order to the first gear 62, second gear 63, third gear 64, fourth gear 65a and fifth gear 66a which mash with each other in the order and the title device is turned. The fourth gears 65a, 65b and fifth gears 66a, 66b are fitted through shaft respectively to both ends of a shaft of one side plate discharge and peeling-off roller 50b and both ends of a shaft of the other side plate discharge and peeling-off roller 50a. Therefore, the plate discharge and peeling-off roller 50a and plate discharge and peeling-off roller 50b forming a pair turn in the opposite direction from each other through starting of turning of the plate sischarge motor 57. A plate discharge and conveying belt 51a and plate discharge and conveying belt 51b are put respectively over between the plate discharge and pulling-off roller 50a and a plate discharge and peeling-off roller 52a and between the plate discharge and peeling-off roller 50b and a plate discharge and peeling-off roller 52b.
