    摘要： A sheet processing apparatus is provided with a carry-in path for guiding a sheet from a carry-in entrance, a shift roller provided in the carry-in path to transport the sheet, while shifting, a carry-in roller positioned on the downstream side of the shift roller to carry the sheet from the carry-in path toward a collection tray, and a punch shift unit provided on the upstream side of the carry-in roller to process an end portion of the sheet in a processing position. The punch shift unit shifts in the same direction as the shift roller, a shift amount of the punch shift unit is set to be equal to a shift amount of the shift roller or more, and the end portion processing unit is thereby already positioned in an end portion processing position or a position near the processing position after shifting the sheet.

    摘要： A sheet folding apparatus includes: a conveying roller conveying a sheet in a predetermined conveying direction; a folding roller pair disposed downstream of the conveying roller in the conveying direction and rotating while nipping a predetermined position of the sheet to form a fold; a conveying path for conveying the sheet in the conveying direction from the conveying roller to the folding roller pair; an abutting member moving downstream in the conveying direction and abutting against the predetermined position of the sheet to bend the sheet downstream; and a loop space where the sheet is bent between the conveying roller and folding roller pair in a direction crossing the conveying direction. The folding roller pair stops while nipping a front end of the sheet fed from to form a loop of the sheet in the loop space, and the abutting member moves to abut against the loop.
