PROBLEM TO BE SOLVED: To provide a paper feeding device in which both trays can be moved up without collapsing large size paper sheets placed to stride over a plurality of trays without using expensive motors and circuits.SOLUTION: The paper feeding device includes: a first paper feeding part including a first tray, and a first elevation motor for moving up the first tray; a second paper feeding part including a second tray, and a second elevation motor for moving up the second tray, the second paper feeding part being disposed side by side with the first paper feeding part in a horizontal direction; a separation plate arranged between the first tray and the second tray; a sensor part; and a controller. The paper feeding device has a tray parallel elevation mode in which paper sheets are set to stride over both the first tray and the second tray and both trays are moved up. The controller moves up both the first tray and the second tray in the tray parallel elevation mode, by alternately repeating a second tray elevation operation in which the first elevation motor is stopped while the second elevation motor is driven and a first tray elevation operation in which the second elevation motor is stopped while the first elevation motor is driven.SELECTED DRAWING: Figure 6 |
