Abstract

PURPOSE:To stabilize the feeding performance of the device by defining the side end position of the side end of a copying material, providing a separation claw in the feeding direction and also providing means for bending the copying material to maintain the same. CONSTITUTION:An intermediate plate 6 is concavely bent at a distance between the contact A of the copying paper with a feed roller 4 and a separation claw 5, and the loaded copying material is maintained in a concave shape. By this procedure, while in the prior device the copying paper is buckled convexly between the feed roller and separation claw by the rotation of the feed roller 4, in the device of the present invention, the copying material is buckled beforehand in the inverse direction. Accordingly, the degree of the buckling of the copying material 1 due to the rotation of the feed roller 4 varies depending upon the quality of the copying material 1 and the degree of bending of the intermediate plate 6. However, in any of the above cases, l becomes greater than l1. Consequently, it is possible to increase the buckling load more than in the prior device. Therefore, the stability of the feeding function relative to the buckling can be improved and double delivery can be removed and the feeding performance can be improved.
