A media folding device includes a stacking portion on which media transported from an introduction path are placed; a folding roller pair that folds the media at a folding position after the media have been stacked in the stacking portion; and a bend forming mechanism that includes a first abutting portion configured to abut against a front end of the media, which are stacked in the stacking portion, in a transport direction, and a second abutting portion that is configured to abut against a rear end of the media, which are stacked in the stacking portion, in the transport direction, and that causes the folding position of the media to be nipped by the folding roller pair the folding roller pair by shortening the relative distance between the first abutting portion and the second abutting portion to bend the media toward the folding roller pair.

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.

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 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 printing device includes a sheet placement plate, an ejection roller module and an ejection control module. The ejection roller module is located near the sheet placement plate to eject at least one paper sheet. The ejection control module is connected with the ejection roller module. The ejection roller module is selectively in a released state or an ejection state under control of the ejection control module. When the ejection roller module is in the released state, the at least one paper sheet is transferred to the sheet placement plate through the ejection roller module. The ejection roller module is in the ejection state, the at least one paper sheet is outputted by the ejection roller module.

An image reading device includes: a document delivery unit for delivering a document loaded on a document loading platform to a document transport path; a flip-up detector for detecting flip-up of the document when the document is delivered; a metal detector for detecting metal attached to the document when the document is delivered; and a staple determination unit for determining whether or not a stapling process is applied to the document based on detection results of the flip-up detector and the metal detector.

A medium conveying apparatus includes a suctioner that suctions a medium of a plurality of media to a feed belt, a driver that moves the feed belt to feed the medium, a first side blower that blows air at a first airflow rate to a first end face of the medium, a second side blower that blows air at a second airflow rate to a second end face of the medium, and a controller that controls the first side blower to blow air to the first end face at a third airflow rate that is greater than the first airflow rate and the second airflow rate when the medium has not been auctioned to a first portion of the feed belt close to the first end face and has been auctioned to a second portion of the feed belt close to the second end face.

A media folding device includes a stacking portion on which media transported from an introduction path are placed; a folding roller pair that folds the media at a folding position after the media have been stacked in the stacking portion; and a bend forming mechanism that includes a first abutting portion configured to abut against a front end of the media, which are stacked in the stacking portion, in a transport direction, and a second abutting portion that is configured to abut against a rear end of the media, which are stacked in the stacking portion, in the transport direction, and that causes the folding position of the media to be nipped by the folding roller pair the folding roller pair by shortening the relative distance between the first abutting portion and the second abutting portion to bend the media toward the folding roller pair.

A sheet stacking apparatus includes an ejector, a stacker, a wall, and an upper surface detector. The ejector ejects a sheet, and the stacker stacks the sheet ejected from the ejector. The wall contacts a trailing end of the sheet ejected from the ejector in an ejection direction to align the sheet. The upper surface detector detects an upper surface on a trailing end side of the sheet stacked on the stacker in the ejection direction. When the sheet moves toward the wall, the upper surface detector moves from a home position in which the upper surface detector detects the upper surface of the sheet to a retracted position in which the upper surface detector does not contact the sheet moving toward the wall.

A postprocessing apparatus includes a horizontal alignment plate, a binder, a tray, and a shift actuator assembly. The horizontal alignment plate is positioned to align sheets in a sheet width direction. The binder binds sheets to form bound sheet bundles. The bound sheet bundles are stacked on the tray. The shift actuator assembly shifts the bound sheet bundles in the sheet width direction. A postprocessing controller controls the shift actuator assembly to shift the bound sheet bundles such that swollen portions of the bound sheet bundles are shifted inward of the horizontal alignment plate in the sheet width direction when the processed sheets are piled on the tray to the vicinity of the horizontal alignment plate.
