A post-processing device (200) includes a circulation conveyance path, a zeroth conveyer (R0), and a controller (50). The circulation conveyance path includes a first conveyance path (W1), a second conveyance path (W2), a third conveyance path (W3), a first conveyer (R1), a second conveyer (R2), and a third conveyer (R3). The first and second conveyers convey a preceding sheet (P1) along the first and second conveyance paths. The third conveyer conveys it from the third conveyance path to the first conveyance path. The zeroth conveyer conveys a following sheet (P2) toward the first conveyer. The controller controls the third conveyer to stop the preceding sheet, subsequently controls the zeroth conveyer and the third conveyer to overlay the preceding sheet with the following sheet to form a sheet bundle (Q) having a shift amount (G) between a leading edges of the preceding sheet and the following sheet and strike the leading edges of the preceding sheet and the following sheet against the first conveyer.

A control method for forming an image includes receiving a pending image-forming job, and obtaining pending image-forming data and image-forming configuration information in the pending image-forming job, the image-forming configuration information including total page number corresponding to the pending image-forming job; performing image-forming operation on an image-forming medium according to the pending image-forming data and the image-forming configuration information; under satisfied predetermined conditions, controlling a discharge distance of at least one page of the image-forming medium of the pending image-forming data to be different from a discharge distance of other pages of the image-forming medium, or controlling a discharge distance of at least one page of the image-forming medium of the pending image-forming job to be different from a discharge distance of the image-forming medium of a previous image-forming job.

A post-processing device for processing a sheet includes a post-processing section for post-processing a sheet; a buffer section for temporarily staying a plurality of sheets at an upstream of the post-processing section; and a conveying section for conveying, one by one, the plurality of sheets stayed at the buffer section to the post-processing section.

An apparatus and a corresponding method involve storing value documents, in particular bank notes, to a storage device and to a value-document processing system. A stacker wheel is arranged to receive value documents and dispense them one after the other. A transport device is arranged to receive the value documents dispensed one after the other by the stacker wheel and to transport them in such a way that the value documents come to lie on top of each other in a shingled manner. A storage device for storing the value documents lying on top of each other in a shingled manner is provided.

An example stacking system comprises a stacking member movable between a first position in which the stacking member is configured to partially support a first stack of printed substrates, and a second position in which the stacking member is disengaged from the first stack. A receptacle positioned below the stacking member is configured to hold a second stack of printed substrates. A controller is configured to cause the stacking member to move between the first position and the second position when the first stack satisfies a criterion, thereby depositing the first stack into the receptacle on top of the second stack.

Example output assemblies for a printer device and printer devices incorporating the output assemblies are disclosed. In one example, the output assembly includes a support surface to support print media that is dispensed from the printer device along a feed direction. In addition, the output assembly includes a side surface that is coupled to the printer device and disposed above the support surface. The side surface is to transition between a first position and a second position. When the side surface is in the second position, the side surface is extended away from the printer device in the feed direction from the from the first position.

A medium ejection apparatus including: a placement mount on which media are placed; a medium-leading-edge position restriction part that moves between a restriction position at which the restriction part restricts a position of a leading edge portion of a medium ejected toward the placement mount with reference to an ejection direction of the medium and a retracted position retracted from the restriction position; and a medium position control unit that controls the medium-leading-edge position restriction part such that the medium-leading-edge position restriction part performs a leading-edge restriction operation of moving from the retracted position to the restriction position and moving from the restriction position to the retracted position when the medium-leading-edge position restriction part and an upper surface of a medium are not in contact with each other.

A three side trimmer has a trimming unit 1, an accumulating unit 3, a discharge unit 2 and a conveying mechanism 4 conveying trimmed booklets BK to the accumulating unit. The accumulating unit has a shelf 5 movable in a vertical direction, and a drive roller conveyor 7 on the shelf. The accumulating unit, in a mode, delivers the trimmed booklets to the discharge unit at every accumulation of a predetermined number of the trimmed booklets and, in another mode, accumulates the trimmed booklets without delivering.

An example stacking system comprises a stacking member movable between a first position in which the stacking member is configured to partially support a first stack of printed substrates, and a second position in which the stacking member is disengaged from the first stack. A receptacle positioned below the stacking member is configured to hold a second stack of printed substrates. A controller is configured to cause the stacking member to move between the first position and the second position when the first stack satisfies a criterion, thereby depositing the first stack into the receptacle on top of the second stack.

A device for offsetting sheets as they are conveyed in a paper path toward a stacker includes a narrow channel mounted to a set of linked arms which when moved in a process direction (upstream-downstream) articulate in a cross process direction (inboard-outboard) to register the sheets at various locations for stacking or finish processing. The linked arms keep the channel parallel to the paper path at all times regardless of inboard-outboard offset.
