A device with a collecting station collects copy sheets which can be provided with a Z-fold in a folding station. The folding station is situated in a transport path for unfolded copy sheets which leads to the collecting station. The folding station is formed by a first pair of folding rollers, the folding nip of which is situated in the transport path, and a second pair of folding rollers, the folding nip of which is situated in a folding path branching off from the transport path. The direction of rotation of the folding rollers is reversible.
An image forming and binding system and method for producing a booklet of a document file, in which images of two pages of the document file are formed on each side of a full-size sheet (such as an A3 or B4 size sheet) conveyed in its longitudinal direction and an image of one page of the document file is formed on each side of a half-size sheet half the size of the full-size sheet (such as an A4 or B5 size sheet) conveyed in its lateral direction, and in which the full-size sheet conveyed in its longitudinal direction is folded in two at its center portion in the longitudinal direction thereof and the folded full-size sheet is stacked one upon another to be bound at its folded side edge portion and the half-size sheet conveyed in its lateral direction is conveyed without being folded to be stacked and bound while being mixed with the folded full-size sheet, so that blank pages in the booklet, which are caused when the number of total pages of the document file is not a multiple number of 4, are reduced.
A sheet finisher for executing preselected processing with a sheet conveyed thereto of the present invention includes a first processing tray configured to temporarily store the sheet and deliver it. A first and a second path are positioned downstream of the first processing tray in a direction of sheet conveyance and configured to convey a first and a second sheet stack, respectively. The first path conveys the first sheet stack upward over the downstream portion of the first processing tray while the second path conveys it downward over the same. A switching device selects either one of the first and second paths. The sheet finisher of the present invention is low cost and highly productive and space saving.
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.
A paper processing apparatus according to one or more embodiments includes a first and second convey mechanism, a first and second alignment mechanism, and a folding mechanism, where the second alignment mechanism is configured to align a paper bundle conveyed by the first convey mechanism in the vicinity of a folding position to fold the paper bundle, and the second convey mechanism is configured to convey the paper bundle aligned by the second alignment mechanism to the folding position, and the folding mechanism is configured to fold the aligned paper bundler at the folding position.
