A document bundler for a bill validator includes a document path, a transportation unit, and a clamp mechanism. The transportation unit is adapted to move a plurality of documents in series through the document path. The clamp mechanism includes a pushing member. The clamp mechanism is adapted to clamp a first document of the plurality of documents with the pushing member to inhibit movement of the first document by the transportation unit while a second document of the plurality of documents is transported substantially alongside the first document in the document path. The second document residing substantially alongside the first document forms a document bundle. Related apparatus, systems, techniques, and articles are also described.

A sheet processing device includes a housing, a sheet stacking portion, a sheet discharge portion, a contact member, a conveyance unit, and an association mechanism. A sheet discharge portion is disposed in the housing and faces a space over the sheet stacking portion, the sheet discharge portion including a pair of discharge rollers. The contact member is disposed in the sheet discharge portion, and is movable to project into a sheet conveyance passage to come into contact with a surface of the sheet. The conveyance unit is selectively mounted in the space of the housing, and is configured to receive a sheet delivered by the pair of discharge rollers and convey the sheet. The association mechanism is operable to cause the contact member to recede from the sheet conveyance passage in association with the mounting of the conveyance unit in the housing.

A sheet feeder including a driving mechanism moving a stopper, an end of the stopper in a first position being closer to a pickup roller axis than a part of a roller surface of a pickup roller, the end of the stopper in a second position being farther from the pickup roller axis than the part of the roller surface, and a movable set guide having a first surface facing in a particular direction to become farther from the roller surface, the first surface being farther from the pickup roller axis than all the roller surface when the set guide is in a third position and contacts the stopper in the first position, the first surface being closer to the pickup roller axis than the part of the roller surface when the set guide is in a fourth position and separated away from the stopper in the second position.

The device for producing packages of stacked materials consisting of a plurality of individual signatures comprises a first conveying unit, which defines a signature path. The first conveying unit moves the signatures along the signature path into a vertical position. The device also comprises a stacking table with a support surface for supporting the signatures, which are arriving with a vertical orientation. The stacking table comprises a second conveying unit, which moves the stacked signatures in a conveying direction of the stack. A control unit switches a tilting device between an active state, in which the tilting device tilts or compresses an upper area of the stacked signatures, and an inactive state, in which the tilting device exerts no effect on the stacked signatures.

When a face of a paper sheet to be discharged on which an image is formed faces downward, a paper discharge device divides an image region of image data on the paper sheet to be discharged into areas along a discharge direction, detects an area in which maximum image density for each divided area is higher than or equal to a specified threshold, and controls a discharge angle so that the detected area does not come into contact with a stacked paper sheet until the paper sheet to be discharged has been discharged from a discharge roller.

At a printer that feeds a continuous paper unwound from a paper sheet supply unit in a sheet-shape to a printing head portion side via a damper portion, and then prints on a label of the continuous paper, the damper portion is made of a transparent material.

A post-processing device includes a processing tray, an aligning plate, a transport section, a feeding section, and a pressing section. A sheet before being subjected to stapling processing by a stapler is to be mounted on the processing tray. The aligning plate aligns ends of a plurality of sheets. The transport section transports the sheet toward the aligning plate. The feeding section is provided between the transport section and the aligning plate and feeds the sheet in a transport direction. The pressing section is provided between the transport section and the aligning plate and applies, to the sheet, a pressing force having a component in a direction opposite from the transport direction. Further, the pressing section applies the pressing force to the sheet before the feeding section applies a feeding force to the sheet.

A post-processing device includes a first discharge section that discharges a medium subjected to recording by a recording device, a first tray on which the medium discharged by the first discharge section is mounted, a post-processing section that performs post-processing on the medium mounted on the first tray, a pressing section configured to perform a leading-end pressing operation of lowering a leading end of the medium by pressing the medium discharged by the first discharge section, and a control section that controls the pressing section, in which the control section performs the leading-end pressing operation after the medium is mounted on the first tray.

A paper sheet handling apparatus includes a movable unit that changes a size of a taking-out space by moving in a direction of approaching a paper sheet discharged to the taking-out space and a direction of retreating the paper sheet, in which the movable unit includes a movable unit main body and a pressing unit movable to a storage position where the pressing unit is moved along the movable unit main body and a pressing position where the pressing unit presses the paper sheet.

A relay transport device configured to relay and transport a medium fed from the feeding device to the recording device includes a first restriction section having a first restriction surface configured to position one first edge of the medium in a width direction of the medium fed from the feeding device; a transport section configured to transport the medium toward the first restriction surface; a first auxiliary guide disposed downstream of the first restriction section in the transport direction and having a first auxiliary guide surface configured to restrict a position of the first edge of the medium; and a second auxiliary guide disposed on an opposite side from the first auxiliary guide with the medium interposed therebetween and having a second auxiliary guide surface configured to restrict a position of a second edge of the medium on the opposite side from the first edge.
