Abstract: The invention concerns a hole-punching processor that forms punched-holes, for binding sheets into a file, on the sheets, which are ejected after images are formed on them from an image forming apparatus such as, for example, a copying machine, a printer, a facsimile machine or a compound machine thereof. The hole-punching processor forms a punched-hole on a sheet residing in a conveying path for conveying the sheet through the hole-punching processor. The hole-punching processor includes a hole-punching device being movable in a direction perpendicular to a conveyance direction of the sheet and a sheet-edge detector to detect a side-edge of the sheet in a direction parallel to the conveyance direction of the sheet. The hole-punching device moves with the sheet-edge detector to a center of the sheet, based on positional information of the side-edge detected by the sheet-edge detector, to punch a hole in the sheet.

Abstract: A sheet processing apparatus has a function of stapling sheets together, wherein the sheets are fed from an image forming apparatus one by one after images are formed on the sheets. The sheet processing apparatus includes a stapler to staple the sheets together, a sheet guide which guides the sheets along a sheet transporting path from the image forming apparatus to a position at which the sheets are stapled by the stapler, and a reference surface against which edges of the sheets are butted to stop movement of the sheets. The sheets are guided along the sheet transporting path by the sheet guide and the edges of the sheets are butted against the reference surface at a same position relative to a sheet conveying direction, irrespective of whether the sheet processing apparatus is in a stapling mode in which the stapler staples the sheets or a non-stapling mode in which the stapler does not staple the sheets, and irrespective of sizes of the sheets.

Abstract: An image forming apparatus, having a sheet ejection section, provided in an upper portion of the image forming apparatus, for ejecting a recording sheet onto an upper surface portion of the image forming apparatus; a sheet post-processing apparatus for receiving the recording sheet, ejected from the sheet ejection section, so as to perform a post-processing operation upon the recording sheet; and a coupler for coupling the sheet post-processing apparatus with the image forming apparatus so that at least a part of the post-processing apparatus is located on the upper surface portion of the image forming apparatus.
