  • Patent number: 7681873
    Abstract: The present invention provides a sheet processing apparatus, such as a finisher or sorter, for implementing predetermined processing such as alignment and stapling on an inserted sheet material (i.e. any sheet-form recording medium such as recording paper, transfer paper, or an OHP sheet), and an image forming apparatus comprising the sheet processing apparatus. The sheet processing apparatus comprises a rear end fence horizontal portion that contacts the end portion of the sheet member on the upstream side of a sheet member conveyance direction during alignment of the sheet member, a rear end fence vertical portion for supporting the other parts of the sheet member, and a staple unit for stapling the sheet member. The stapling direction in which a staple is punched by a stapler of the staple unit is set to be parallel to the rear end fence horizontal portion that contacts the rear end portion of the sheet member.

  • Patent number: 7419151
    Abstract: A sheet processing apparatus includes a first roller pair conveying a sheet received from an external apparatus, a second roller pair conveying the sheet conveyed from the first roller pair, a jogging tray configured to receive the sheet conveyed from the second roller pair and jog the received sheet, and a binding device configured to bind a stack of sheets received and jogged by the jogging tray. The second roller pair can be driven to rotate such that sheets received from the external device and conveyed by the first roller pair one after another are pinched by the second roller pair one after another while being overlapped one upon another with leading edges thereof shifted stepwise one after another and are held by the second roller pair to be further conveyed to the jogging tray.

  • Patent number: 7389979
    Abstract: A sheet processing apparatus receives sheets discharged from an image forming apparatus one after another on a binding tray to be stacked on top of another, jogs each sheet as the sheet is received on the binding tray, binds a set of the sheets on the binding tray with a binding device, and discharges the bound set of the sheets from the binding tray. Sheets received from the image forming apparatus one after another after the binding device has started binding the set of the sheets on the binding tray and before the binding tray has returned from a discharging position to a receiving position are received one after another, stacked on top another and held on a sheet holding device. The sheet holding device releases the held sheets to be fallen and received on the binding tray after the binding tray has returned to the receiving position.

  • Patent number: 6983931
    Abstract: A binding apparatus includes a receiving device configured to receive a sheet from outside and convey the sheet, and a sheet folding device configured to fold the sheet, conveyed by the receiving device, in two at a center portion thereof in a direction the sheet is conveyed, so as to be a folded sheet, and convey the folded sheet with the folded portion thereof being a leading edge of the folded sheet. A jogging device includes a jogging table and is configured to receive and jog the folded sheet, conveyed by the sheet folding device, one after another, so as to be stacked into a stack of folded sheets on the jogging table. A binding device is configured to bind the stack of folded sheets stacked on the jogging table at an edge portion of the stack of folded sheets at the side where the folded portion of each folded sheet of the stack of folded sheets is located. A discharging device is configured to discharge the bound stack of folded sheets.
