PAPER SUPPLY DEVICE

摘要

Provided is a paper supply device that can increase a sheet stacking amount without deepening the depth of a paper supply tray. The paper supply device is provided with: a paper supply tray (10) that carries sheets; a feed out roller (13) that feeds out sheets by contacting the uppermost surface of the sheets on the paper supply tray (10); and a separation means (14 15) that supplies paper by separating the sheets fed out by the feed out roller (13). The paper supply device is provided with: a rising/falling tray (41) that supports the tip side of the sheets carried at the paper supply tray (10) moves the uppermost surface of the sheets to a feed out position and can rise/fall; a first driving means that causes the rising/falling tray (41) to rise/fall; a second driving means that causes the feed out roller (13) to rise/fall; and a control means that controls the driving of the first and second driving means. The control means controls the first and second driving means in a manner so as to raise the rising/falling tray (41) until the uppermost surface of the sheets reaches the feed out position and then to cause the feed out roller (13) to fall to the position of contact with the uppermost surface of the sheets.
