PURPOSE:To prevent a top of paper from being folded as well as to stack it accurately, by finding the moving direction and travel of a guide member truing up both front and rear ends of the paper with a control circuit, while energizing its driving source via a connecting member, and moving the guide member. CONSTITUTION:With indication of a control circuit 16, a front guide alone is driven via a connecting selector device 14 and it is moved till a position sensor 15 is turned on. Next, a rear guide 11 is driven (13) up to a travel limit point B via the connecting device 14. Then, according to size of paper 20 to be fed, the front guide 10 is moved to an A point, and a distance between points A and B is adjusted to size of the paper 20. A feed roller 21 is controlled (16), rotating it toward an arrow 31, and the paper 20 is delivered. If a rear end C of the paper 20 fails to get out of the feed roller 21, the paper 20 is naturally dropped down between the front guide 10 and the rear guide 11. The succeeding paper is stacked up likewise. With this constitution, a tip of the paper prevented from being folded, and plural sheets of paper are accurately stacked.
