Abstract
A sheet transport device includes 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, and 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, and a controller. 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 so 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.
