According to examples, a printing apparatus may include an output bin that is laterally translatable between a retracted position and an extended position. The printing apparatus may also include a sensor to detect a height of a stack of media on the output bin while the output bin is in the retracted position and a controller. The controller may determine whether the detected height of the stack of media on the output bin exceeds a certain level and in response to a determination that the detected height of the stack of media exceeds the certain level, laterally translate the output bin from the retracted position to the extended position.

To prevent displacement of first fold positions and collapse of discharged and stacked sheets when sheet fold processing is performed a plurality of times for each sheet. First fold processing is applied to a sheet conveyed to a conveying path by a rotating body pair 22. The sheet that has been subjected to the first fold processing is fed back to the conveying path while a first fold line is being opened. Then, second fold processing is applied to the sheet that has been fed back to the conveying path by the rotating body pair 22. The resultant sheet is discharged with the first fold line opened.

A post-processing device includes a carrying roller, a conveying member, a transporting member and a processing part. The carrying roller is configured to be rotated to carry a sheet one by one to a processing tray along a conveyance direction. The conveying member is configured to convey the sheet carried by the carrying roller to a receiving position on the processing tray. The conveying member has a rotation shaft and a plurality of contact pieces protruding from the rotation shaft so as to come into contact with the sheet carried on the processing tray. The contact piece is made of elastic material. The conveying member is rotated at a rotation speed higher than a rotation speed of the carrying roller when the sheet carried by the carrying roller is conveyed to the receiving position on the processing tray.

A sheet discharge apparatus includes: a discharger that discharges a sheet; a loading part on which the sheet discharged from the discharger is loaded; an abutment member that abuts against a rear end of the sheet in a direction of discharging to align the sheet loaded on the loading part; a pull-back member that performs a pull-back operation by contacting with the sheet discharged from the discharger to pull back the sheet toward the abutment member; and a hardware processor that controls the pull-back member. The hardware processor performs the pull-pack operation on a sheet bundle when determining that the sheet bundle bound by a binder is discharged from the discharger.

A sheet loading apparatus for carrying a sheet loaded in a first tray to a second tray includes: a grip portion configured to grip the sheet; a sliding portion configured to move the grip portion between a sheet gripping position and a sheet release position; a lift portion configured to move the grip portion and cause the grip portion to emerge from the sheet loading surface; and a common power transmission portion configured to transmit power to both the sliding portion and the lift portion, wherein in one cycle, after the sliding portion moves the grip portion to a downstream side, the lift portion moves the grip portion downward of the sheet loading surface to cause the grip portion to reach the release position, and after the sliding portion moves the grip portion to the upstream side, the lift portion moves the grip portion to the gripping position.

A sheet cutting apparatus includes a cutting unit configured to cut a sheet, a blowing unit configured to send air toward the cutting unit, a container unit configured to contain scraps generated when the sheet is cut, a scrap path configured to allow the scraps travelling toward the container unit from the cutting unit to pass through, wherein the scrap path is formed of a member provided with openings for allowing the air sent by the blowing unit to pass through.

A paper-made staple binds a sheet bundle subjected to folding processing by a folding blade and a folding roller. The paper-made staple includes a pair of leg portions inserted into the sheet bundle and then bent inward; and a connection portion that connects the leg portions in a staple longitudinal direction. The connection portion has, at an edge portion thereof, a cut in a direction crossing the longitudinal direction so as to correspond to a predetermined folding position of the sheet bundle for the purpose of facilitating the folding of the connection portion, and the cut is formed inward from the edge portion so as to have a substantially triangular shape and is provided on both edge portions of the connection portion of the paper-made staple.

A bundle of printing media by eco-stapling often has a smaller thickness than a bundle of printing media by needle stapling by the thickness corresponding to an amount of used staples, although they have the same number of printing media, and there is room capable of stacking bundles in many cases in the eco-stapling. According to an embodiment, when a printing medium that has undergone an image forming process is taken in, stapling processing is performed on the printing medium, and then the printing medium is discharged to the tray, the following process is performed. That is, when the process is performed in accordance with instructed stapling processing, and the printing medium that has undergone the process is discharged outside the apparatus, the amount of printing media stacked on the tray is controlled in accordance with instructed stapling processing.

A medium feeding device includes a medium placing portion, a feeding roller that feeds paper, a medium movement detecting portion that is positioned on a placing region of the paper of the medium placing portion in a medium feeding direction and is capable of detecting movement of the paper being fed in a width direction intersecting the medium feeding direction, and a controller that stops feeding of the paper in a case in which a physical quantity relating to movement of paper in the width direction exceeds a predetermined threshold based on a detected result by the medium movement detecting portion.
