Claim 13:
14. A sheet transport device comprising:
a sheet load tray on which a sheet is loaded;
a detector that detects whether or not the sheet exists on the sheet load tray;
a feeder that feeds the sheet one-by-one from the sheet load tray;
a sheet-load-tray ascend-descend unit that moves the sheet in a sheet loading direction to set an uppermost sheet at a sheet feed position of the feeder;
a controller, wherein in a case where the sheet is detected by the detector, the controller causes the sheet load tray to ascend or descend before the feeder starts to feed the sheet such that ascending-descending operation for moving the sheet load tray between the sheet feed position and a descent position located below the sheet feed position is performed at least once; and
a stopper that comes into contact with lateral edges of the sheet in a direction intersecting a feeding direction of the sheet when the sheet load tray ascends to the sheet feed position, so as to cause a sheet bundle to bend,
wherein the stopper causes the sheet bundle to bend by repeatedly moving in the direction intersecting the feeding direction of the sheet via a missing-tooth gear that is rotationally driven in accordance with ascending of the sheet load tray.
