A sheet post-processing device of the present disclosure is provided with a punch hole forming device, a processing tray, an ejection tray, a conveyance roller pair, an ejection roller pair, and a stiffening member. In a case where a sheet through which punch holes have been formed is to be ejected on the ejection tray without being subjected to post-processing on the processing tray, in a state where the stiffening member is retracted in a direction away from the sheet, the conveyance roller pair conveys the sheet until at least a tip end thereof reaches on the ejection tray.

A method for producing a roll of stretch film comprises the steps of passing a stretch film web over a first roller, and winding the stretch film web around a second roller against the first roller, where the first roller has a surface for enabling the introduction of air into the wound stretch film web.

A post-processing device is provided with a post-processing unit which performs post-processing of a recording medium on which recording is performed, a transport path through which the recording medium is transported, or a deformation suppressing unit which suppresses deformation of the recording medium on a mounting unit on which the recording medium is mounted, in which the deformation suppressing unit is controlled based on a predetermined parameter related to recording processing with respect to the recording medium.

A self-service terminal, apparatus, and method for corrugating received media items is disclosed. A bin is provided for storing media items. A pathway selectively conveys a received media item to the bin. An apparatus that include as set of paired corrugating drive rollers is mounted in the pathway for creasing the received media item as it is conveyed to the bin. The set of paired corrugating drive rollers has a plurality of first corrugating rollers mounted in a spaced apart fashion on a common shaft, each of the first corrugating rollers having an outwardly facing rounded-V profile, and a plurality of second corrugating rollers mounted in a spaced apart fashion on a common shaft, each of the second corrugating rollers having an inwardly facing slot. Each of the plurality of first corrugating rollers is positioned adjacent to a corresponding one of the plurality of second corrugating rollers.

According to one embodiment, a sheet post-processing apparatus includes a standby unit, a processing unit, and a discharge unit. The standby unit puts a sheet on standby. The processing unit is disposed below the standby unit. The processing unit includes a conveyance reference plane, a distance between which and a conveyance reference plane for the sheet in the standby unit changes to decrease from an upstream side toward a downstream side in a conveying direction of the sheet. The processing unit processes the sheet supplied from the standby unit. The discharge unit is disposed on the downstream side in the conveying direction of each of the standby unit and the processing unit. The discharge unit is provided with an opening section for causing the sheet discharged from the standby unit or the processing unit to pass.

A sheet conveying device has a pair of upper discharge rollers including a first discharge roller and a first following roller, a second discharge tray, a corrugation member, and a moving mechanism. The first discharge roller is rotatable in forward and reverse directions. The corrugation member corrugates the sheet by making contact with its sheet face. The moving mechanism moves the corrugation member between a first position, where it makes contact with the sheet face of the sheet, and a second position, where it is located above, away from, the nip portion of the pair of upper discharge rollers. An image forming apparatus incorporates such a sheet conveying device.

A media accumulator-ejector for use with an imaging apparatus. Rotatable upper and lower roll assemblies are located above and below a media accumulation zone comprised of an accumulation plate and positioned to receive media exiting an imaging device. The roll assemblies are moveable like jaws between an open position where media can accumulate on the accumulation plate without interference with the roll assemblies and a clamping position where the accumulated media is grasped by the upper and lower roll assemblies. The upper and lower roll assemblies are then rotated to eject the accumulated media from the accumulation plate. The upper and lower roll assemblies can also grasp and continuously eject individual sheets of media at a predetermined process speed.

An image recording apparatus includes: a recording section which records an image on a sheet conveyed in a conveyance direction in a conveyance route; a first abutment member having a plurality of first abutment portions arranged apart from each other in a width direction orthogonal to the conveyance direction, and configured to abut against the sheet conveyed in the conveyance route; a first supporting member which supports the first abutment member; and a plurality of second abutment members which are supported by the first supporting member at both sides in the width direction, respectively, of the first abutment member, at a distance from the first abutment member, and each of which has a second abutment portion capable of contacting with the sheet conveyed in the conveyance route.

An image forming apparatus includes plural medium transport paths that branch at a predetermined branching position and along which a medium is transported in a curved state; a switching member disposed at the branching position and including a guide surface that allows the medium to be transported along one of the medium transport paths, the switching member switching between the medium transport paths; an output unit that outputs the medium toward a stacking portion, on which the medium is to be stacked, while corrugating the medium; and a guide portion that guides the medium from the branching position toward the output unit in a region in which the medium is corrugated.

An image forming apparatus includes a conveying guide and a sheet member. The conveying guide is provided in a joining section and guides a sheet to a conveying roller pair along a main conveying path. The sheet member is provided in the joining section and configured to form a lower conveying path with the conveying guide and to guide the sheet from an upper conveying path toward the main conveying path. The conveying guide has a convex guide part and planer guide parts. The convex guide is provided at a center portion and projects toward the sheet member. The planer guide parts are provided on both sides of the convex guide part. A first gap formed between the convex guide part and the sheet member is narrower than a second gap formed between the planer guide part and the sheet member.
