Abstract
A first tray is adapted to stack a paper discharged from a discharge port thereon. A lifter is operable to raise or lower the first tray. A detector is operable to detect a stacked state of the paper and the first tray. In a case where the paper is discharged onto the first tray, the first tray is raised or lowered based on the stacked state detected by the detector so as to keep a distance from the discharge port to an uppermost paper of the paper stacked on the first tray within a predetermined range.
