Abstract:
1. A sheet processing apparatus comprising: a conveying portion which conveys a sheet in a conveying direction; a stacking portion on which the sheet conveyed by the conveying portion is stacked; a first processing unit which performs a first process to the sheet at a first process position on the stacking portion; a second processing unit which performs a second process to the sheet at a second process position on the stacking portion, the second process position being at the downstream side in the conveying direction of the first process position; a receiving member which is movable in the conveying direction of the sheet so as to perform positioning of the sheet in the conveying direction by receiving one end in the conveying direction of the sheet conveyed to the stacking portion; a controlling portion which controls the driving unit so that the receiving member is moved in the conveying direction so as to perform positioning of the sheet at the first process position to perform the first process and then positioning of the sheet at the second process position to perform the second process in a case that the second processing unit performs the second process after the first processing unit performs the first process to the sheet, and so as to perform positioning of the sheet at the second process position in a case that the second processing unit performs the second process to the sheet passed through the first process position without being positioned at the first process position to perform the first process.
