特徴とする給紙装置。It has a feed roller that rotates in the paper feeding direction, and a separation roller that pinches the paper path and comes into pressure contact with it, is applied a constant torque in the opposite direction to the paper feeding direction via a torque limiter, and can rotate in either direction. However, in a paper feeding device that separates and feeds multiple sheets of paper, the polishing direction of the outer circumferential surface of the rubber outer layer of each of the feed roller, separation roller, and two-step roller described above is different from that of the feed roller with respect to the paper feeding direction. A paper feeding device characterized in that the separation roller is set to perform sequential feeding with respect to a non-feeding direction.
