を特徴とする複写機の給紙装置。A feeding roller 2 disposed on the paper tray 1 feeds the laminated paper 3 on the paper tray 1 sequentially from the bottom paper to a separation roller 4, and the separation roller 4 separates the bottom paper one by one and feeds it. In the paper feeding device that feeds the paper to the main unit 6 using rollers 5, a pressing piece 7 that can freely move toward and away from the topmost paper of the stacked paper 3 is disposed on the upper part of the paper loading table 1 facing the feeding roller 4, and the above-mentioned separation A first paper sensor S1 is disposed between the roller 4 and the feed roller 5, and a second paper sensor S2 is disposed at a position past the feed roller 5.
presses the stacked paper 3 toward the feeding roller 2 side, and the first paper sensor S1 detects the leading edge of the paper fed out by the rotation of the feeding roller 2, and causes the suppressing piece 7 to separate from the stacked paper 3, thereby pushing the leading edge of the paper. A paper feeding device for a copying machine, characterized in that the second paper sensor S2 detects after the paper has passed the feed roller 5, and the rotation of the delivery roller 2 and separation roller 4 is prevented.
