Abstract
A sheet processing apparatus which is capable of enhancing productivity in flattening a fold top of a sheet bundle. The sheet processing apparatus has a conveying unit that conveys a folded sheet bundle to a processing position, and a holding unit that holds the sheet bundle conveyed by the conveying unit. When the folded sheet bundle has been conveyed by a predetermined distance after a leading end of the sheet bundle has been detected and before the sheet bundle reaches a processing position, the holding unit starts holding the sheet bundle, and then the conveying units stops conveyance of the sheet bundle.
Claims5
A sheet processing apparatus comprising:
- a conveying unit configured to convey a folded sheet bundle to a processing position;
- a holding unit, comprising a first holding member and a second holding member, configured to hold the sheet bundle conveyed by said conveying unit in a thickness direction of the sheet bundle by movement of at least one of the first holding member or the second holding member;
- a pressing unit configured to press a fold top of the sheet bundle held by said holding unit at the processing position;
- and
- a control unit configured to cause, while the sheet bundle is being conveyed by the conveying unit, said holding unit to start moving the at least one of the first holding member or the second holding member along the thickness direction of the sheet bundle to hold the sheet bundle before the sheet bundle reaches the processing position, and then cause said conveying unit to stop conveying the sheet bundle so that the sheet bundle stops at the processing position.
