The tooth-lack part 23 of the gear 22 is released from the gearing position with a gear 19 through revolution of the gear 22, and the gear 22 gears with 19, and the gear 19 is revolved clockwise. The revolution force is transmitted to a roll supporting shaft 5 through a unidirectional clutch 20, and then the roll paper 9 supported on the roll supporting shaft 5 is turned clockwise, namely in the direction of rewinding, and the roll paper is rolled back. Then, the roll 9 which is engaged with a paper feeding roller 12 is released.
