<p>PROBLEM TO BE SOLVED: To provide a simply structured and low-cost device capable of surely detecting the amount of stacking on a delivery tray. SOLUTION: A paper sheet loading device comprises a delivery roller 19 for delivering transfer paper sheets, a delivery tray 3 for loading the transfer paper sheets delivered by this delivery roller, detecting means S4 and S16 for detecting the height of the paper sheet of the transfer paper sheets loaded on the delivery tray and a tray vertical movement mechanism for adjusting the highest position of the delivery tray based on detected signals from these detecting means. A DC motor 101 is used as a driving source for the vertical movement mechanism, motor rotational number detecting means 110 and 111 are disposed in the output shaft of the DC motor and a control part for detecting the loading amount of transfer paper sheets on the delivery tray based on the rotational number detecting results of the motor rotational number detecting means 110 and 111 is provided.</p> |
