ABSTRACT:
A sheet discharge device neatly and uniformly aligns edges of print sheets irrespective of the thickness of a print sheet, and exerts the same effect even at a low discharge speed. The sheet discharge device includes: sheet information sensing means for detecting thickness of a print sheet to judge the sheet as a thick sheet, a regular sheet, or a thin sheet; conveying means for discharging the print sheet bearing a printed image in a predetermined direction; a discharge tray that accommodates a stack of the print sheets discharged by the conveying means; wings arranged at a tail end portion of the conveying means, coming in contact with two side edges in a widthwise direction of the print sheet so as to give a U shape curl by curving the sheet in a rough U shape during discharge; control means for commanding, based on the judgment by the sheet information sensing means, the wing to take a predetermined shift mode during discharge of the print sheet; and drive means for moving the wing in a shift mode designated by the control means.
