A postprocessing apparatus stops and positions an image recording sheet delivered from an image forming apparatus at a predetermined position, punches the sheet with a punching unit, and thereafter folds the sheet with a folding unit.

Postprocessing apparatus with two or more finishing devices

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.

Hole-punching processor and image forming apparatus

A sheet finisher having a sheet placing member for placing and adjusting a predetermined number of sheets to which a predetermined processing is carried out thereon; a stapling member for stapling the predetermined number of adjusted sheets; and an air-blowing member arranged above the sheet placing member. The air-blowing member is operated to press each of the sheets against the sheet placing member by blowing air and adjust when each of the sheets to which the predetermined processing is carried out is placed on the sheet placing member, and stapling is performed to the sheets by the stapling member.

Sheet finisher with air blowing member

A sheet folding apparatus having a Z-folding function which incluses a sheet conveyance device for conveying a paper sheet having an image formed thereon and a stopping member capable of moving for adjusting the position thereof provided in a conveyance path in order to stop a paper sheet conveyed by the sheet conveyance device at the leading edge colliding against the stopping member, and forms a fold by introducing the buckle portion of the paper sheet formed by the stopping member between a roller pair composed of two folding rollers and gripping by the rollers. The sheet folding apparatus is provided with a controller for temporarily reducing the rotating speed of each of the folding rollers, at a timing when the paper sheet is gripped between the roller pair.

Sheet folding apparatus

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.

Sheet processing apparatus

A sheet conveyance apparatus includes a guide for the recording sheet formed by a discharging layer. The layer includes an electrically grounded conductive substrate and an organic conductive fiber thereon. The surface of the guide is in close proximity to the surface of the recording sheet.

Sheet conveying apparatus and method wherein the sheet is fed without

In an sheet finishing apparatus for receiving a sheet on which an image has been formed by an image forming apparatus, and for ejecting the sheet after a front side thereof is reversed, the sheet finishing apparatus includes: a sheet conveyor for conveying the sheet fed from the image forming apparatus downstream; a sheet reversing device for receiving the sheet conveyed by the sheet conveyor, and for reversing the front side of the sheet by rotation; a sheet holder provided on a peripheral portion of the sheet reversing device for holding a leading edge portion of the sheet conveyed by the sheet conveyor, the sheet holder capable of being opened or closed; a sheet stopper for blocking the leading edge portion of the sheet to be stopped at a position where the front side of the sheet is reversed by a rotation of the sheet reversing device; and a sheet stacking member for stacking the sheet separated from the sheet reversing device by a further rotation of the reversing device after the leading edge of the sheet is blocked by the sheet stopper.

Sheet finishing apparatus

A sheet finishing apparatus for finishing a sheet, on which an image has been formed, conveyed from an image forming apparatus, the sheet finishing apparatus includes: a sheet ejecting member for ejecting the sheet after finishing; and an exit tray for receiving the sheet ejected by the sheet ejecting member after finishing is conducted. The exit tray includes a movable exit tray member on which the sheet is stacked, and a stationary exit tray member for supporting the movable exit tray member. The movable exit tray member has a sheet stacking surface on which the sheet is stacked, and a stopper portion provided adjacent to the sheet ejecting member to bring an edge of the sheet into contact with the stopper portion. The movable exit tray member is pivotally supported around a supporting shaft provided on a leading edge portion of the stationary exit tray member. An edge portion of the movable exit tray member, which is adjacent to the sheet ejecting means, can be moved upward or downward according to the number of sheets stacked on the movable exit tray.
