Zusammenfassung:	In a post-processing device (sheet discharge device) (60), a pile thickness calculating section (613) calculates, from a type and the number of paper sheets discharged through a sheet output port (606), a thickness of a pile, at its leading end, of sets (P1) of paper sheets on a sheet output tray (piling section) (623), calculates a thickness of the pile at its trailing end from an amount of movement of a lifting section (605), and calculates an angle of inclination of the uppermost paper sheet (P) in the pile from the thicknesses of the pile at its leading and trailing ends, a height of inclination of the sheet output tray (623), and a length of the paper sheets (P). A control section (10) controls a sheet discharge section (652, 607, 602, 620) to change a manner of discharging a subsequent paper sheet set (P1) according to the calculated angle of inclination.
