A sheet processing apparatus is configured to press a fold line that is formed on a sheet. The sheet processing apparatus includes: a sheet supporting unit configured to support the sheet in a pressing direction for pressing the fold line; a pressing unit configured to press the fold line that is formed on the sheet that is supported by the sheet supporting unit; and a pressing-force generating unit configured to generate a pressing force for pressing the sheet supporting unit against the pressing unit at a central part in a direction along which the fold line is formed.

An image forming apparatus comprises a printing module, a transporting mechanism and a sorting module. The printing module prints data on media in order. The transporting mechanism transports the media past the printing module. The sorting module is disposed downstream of the transporting mechanism, and comprises an output mechanism, a rack and a driving pinion. The output mechanism transports the media out in a first direction. The rack is connected to the output mechanism. The driving pinion meshing with the rack drives the rack and the output mechanism to reciprocate in a second direction, different from the first direction, to sort the media into stacks. Thus, the sorting function can be achieved without providing a larger space and moving a discharge tray, and this is advantageous to the miniaturization of the image forming apparatus.

Provided is an image-forming device with which it is possible to achieve a smaller size while suppressing a reduction in visibility or operability of an operation panel. In this image-forming device, paper sheets are discharged from the rear side of the device toward the front side of the device, and the image formation device is provided with: a paper-sheet-loading unit in which the paper sheets are loaded; an operation panel disposed on the downstream-side end in the paper sheet discharge direction of the paper-sheet-loading unit, at least a part of the operation panel being disposed in a loading region of the paper-sheet-loading unit; and a protruding part disposed to the side of the operation panel in the loading region, the protruding part protruding upward from the top surface of the paper-sheet-loading unit, and extending in the paper sheet discharge direction.

A paper medium skew correcting device includes: a support including a pair of fixed stop plates arranged in parallel; a skew correcting tapered roller assembly including a tapered roller, a reference plate located at a large end face of the tapered roller and a transmission shaft a tapered cover plate covering on the tapered roller with a skew correcting passage formed between an inner wall of the tapered cover plate and an outer wall of the tapered roller, an auxiliary pressure roller mechanism is mounted on an outer wall of the tapered cover plate and is configured to press a paper medium against the outer wall of the tapered roller tightly, the tapered cover plate is provided with an opening; and a driving transmission assembly. The device fully uses combined action of centrifugal force and friction force to realize skew correction and conveying of the paper medium.

A printing apparatus includes a feeding roller to feed a sheet, a conveyance roller conveys the sheet, a printing head prints on the sheet, a reversing path that reverses the sheet from a first surface to a second surface, and a control unit that controls feeding of a preceding sheet and a succeeding sheet fed next to the preceding sheet. The control unit starts feeding of the succeeding sheet when a trailing edge of the preceding sheet, which was reversed by the reversing path, reaches a predetermined position and feeds the succeeding sheet so that a distance between the trailing edge of the preceding sheet and a leading edge of the succeeding sheet is within a predetermined range.

A sheet processing apparatus is configured to press a fold line that is formed on a sheet. The sheet processing apparatus includes: a sheet supporting unit configured to support the sheet in a pressing direction for pressing the fold line; a pressing unit configured to press the fold line that is formed on the sheet that is supported by the sheet supporting unit; and a pressing-force generating unit configured to generate a pressing force for pressing the sheet supporting unit against the pressing unit at a central part in a direction along which the fold line is formed.

A printer includes a printing section configured to perform printing on roll paper, a transport surface (hot plate) where the roll paper on which printing has been performed is transported, and a heater unit (heater) for heating the transport surface. The stated transport surface includes a plurality of projections with which the roll paper makes slide contact.

A first feeder contacts a first surface of a first sheet held in a first tray and feeds the first sheet toward a recording unit. A second feeder contacts a first surface of a second sheet held in a second tray and feeds the second sheet toward the recording unit. An inner member is disposed above a standing plate. An outer member comprises an upstream portion opposing the standing plate, and a downstream portion opposing the inner member. The inner member guides the first surface of the first sheet and the first surface of the second sheet. The standing plate guides the first surface of the second sheet. The upstream portion of the outer member guides a second surface of the second sheet, and the downstream portion guides a second surface of the first sheet and the second surface of the second sheet. The standing plate moves relative to the outer member.

A sheet conveyance apparatus includes a body portion, an openable portion supported by the body portion and configured to be opened and closed with respect to the body portion, a first movable guide supported by the openable portion and movable to a first position at which a first conveyance path through which a sheet is conveyed is formed between the first movable guide and the openable portion and a second position at which the first path is opened, a second movable guide movably supported by the first movable guide, and an abutment portion provided in the body portion. In a state where the openable portion is closed, the second movable guide abut with the abutment portion and is held on a position to form a second conveyance path through which the sheet is conveyed.

An improved imbricating method, folding method, and device for producing imbricated streams (3) which are produced from singulated and preferably folded blanks (2) is provided. The method includes taking imbricated bundles of blanks including of a number of overlapping blanks corresponding to the number of the individual streams formed by the blanks of a first individual stream being transported at a distance from one another along a transport surface through a compiling station. In the process, the blanks of the at least one remaining individual stream are first of all deflected vertically with respect to the transport surface by a deflecting device of the compiling station and are then guided in the direction of the first individual stream and are subsequently deposited with an offset onto the blanks of the first individual stream.
