PROBLEM TO BE SOLVED: To provide a sheet post-processor including a configuration capable of suppressing wasteful power consumption by performing power supply corresponding to an actual stacking amount.SOLUTION: An input side of control means is connected with: paper surface detection means detecting the topmost position of sheets discharged on a paper discharge tray; and a kind instruction part of a folding form of the discharged sheet. An output side of the control means is connected with: tray angle change means inclining the paper discharge tray at an angle corresponding to the folding form of the sheet; and a drive motor. The control means variably controls a control current to the drive motor according to a detection result from the paper surface detection means when having horizontally corrected inclination of the topmost sheet by a bulge of the sheet by the folding form of the sheet on the basis of the folding form of the sheet and the inclined angle by the tray angle change means. |
