摘要： A sheet processing apparatus comprises a first conveyer roller pair and a second conveyer roller pair arranged sequentially from the upstream side to the downstream side along a sheet conveyance route of a sheet of paper along with a punching unit disposed between the first and second conveyer roller pairs. The punching unit includes a hole cutting blade that is capable of retractably projecting the hole cutting blade relative to the sheet conveyance route so as to control the position of the hole cutting blade of the punching unit according to the condition of the sheet of paper being conveyed. The apparatus further comprises a control unit adapted to cause the hole cutting blade to project across the sheet conveyance route before the leading end of the sheet of paper being conveyed gets to the punching unit so as to make the leading end of the sheet of paper abut the hole cutting blade and correct the skew, if any, of the sheet of paper.
