Abstract: After a sheet has once passed through a punching position where punching processing is performed, a conveyance roller pair conveys the sheet backward to the punching position. A lateral registration detection sensor detects a side edge position of the sheet in a width direction. When a sheet processing apparatus corrects the side edge position of the sheet by controlling a shift unit configured to move the sheet in the width direction so as to correct the side edge position of the sheet, the sheet processing apparatus sets a shifting amount of the sheet to a value that is a predetermined amount greater than a shifting amount required to correct the side edge position of the sheet according to the side edge position of the sheet detected by the lateral registration detection sensor. After the sheet has passed through the die hole in the backward movement toward the punching position, the sheet processing apparatus sets the shifting amount to the required value.

Abstract: In a sheet detecting sensor, light emitted from a linear light emitting element is blocked by a sheet from entering a light receiving element which is located immediately below the sheet. Only light receiving elements which are not immediately below the sheet, receive light from the linear light emitting element. Light passing through a point in a vicinity of an edge portion of the sheet enters only a light receiving element which is located immediately below that point, but not the other light receiving elements. In addition, even when the position of a sheet varies vertically, the same light receiving element receives light passing through the same point in a vicinity of the edge portion of the sheet. Therefore, even when the position of a sheet varies vertically, the edge position of the sheet can be accurately detected.

Abstract: A sheet registration system for a sheet handling device has a plurality of driven belts. Each belt is entrained about a driven roller and an idler roller. The driven rollers are fixedly mounted on a common drive shaft that is connected to a motor. The idler rollers each have a shaft and the idler shafts are coaxially aligned and parallel to the common drive shaft. Adjacent idler shafts are interconnected.
