PROBLEM TO BE SOLVED: To provide a paper supply device that can increase a sheet stacking amount without deepening the depth of a paper supply tray.SOLUTION: The paper supply device comprises: 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 separation means 14, 15 that supplies paper by separating the sheets fed out by the feed out roller 13. The paper supply device comprises: a rising/falling tray 41 that supports the tip side of the sheets carried in the paper supply tray 10, moves the uppermost surface of the sheets to a feed out position, and can rise/fall; first driving means that causes the rising/falling tray 41 to rise/fall; second driving means that causes the feed out roller 13 to rise/fall; and control means that controls the driving of the first and second driving means. The control means controls the first and second driving means 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. |
