The pickup rollers10and20are vertically moved independently while following up the height position of the uppermost surface of the piled papers P. The first and second feeding units10and20are connected by a plate elastic support member70. The device also comprises a single optical sensor72for detecting the height position at the center of the elastic support member70. The contact state of the pickup rollers12and22with the papers P is detected based on signals detected by the optical sensor72.
