Abstract
A sheet processor has a sheet transportation path, a punching unit for performing a punching operation on the sheets, the punching unit including a punch slide having a punch mechanism thereon, a moving device for moving the punch slide between a sheet punching operation position and a punch slide home position, the movement occurring in a direction transverse to the sheet transportation direction, and a detector for detecting completion of the punching operation by the punching unit. When the detector detects the completion of the punching operation, the moving device moves the punching unit to the punch slide home position.
