A sheet bonding apparatus includes an electrophotographic unit configured to apply powder adhesive on a sheet by an electrophotographic process, a folding portion configured to fold the sheet on which the powder adhesive has been applied by the electrophotographic unit, and a bonding portion configured to heat the sheet folded by the folding portion to bond the sheet by the powder adhesive, wherein the bonding portion and the folding portion are disposed over the electrophotographic unit.

The aligning device receives a sheet conveyed in a sheet conveyance direction in a stackable manner and aligns a position of the sheet in the sheet conveyance direction. The moving mechanism moves the sheet aligned by the aligning device in the sheet conveyance direction together with the aligning device. The controller selectively executes a first mode in which first post-processing is performed on the sheet and then second post-processing is performed on the sheet and a second mode in which the second post-processing is performed on the sheet without performing the first post-processing on the sheet. The controller, in response to a selection of the first mode or the second mode, causes the moving mechanism to adjust a position of the aligning device in the sheet conveyance direction before the aligning device receives the sheet as a target of the first post-processing or the second post-processing, respectively.

An apparatus for treating a stack of sheets of sheet material includes a means for moving the stack of sheets of sheet material towards a first and second fold roller means. The first and second fold roller means are arranged to assist with folding of the stack of sheets of sheet material. The apparatus also includes a first and a second clamping jaw defining a gap. The first and second clamping jaws are arranged to be movable relative to each other to increase and decrease the gap for selective application of a clamping force to the stack of sheets of sheet material having passed between the first and second fold roller means. The first and second fold roller means are mounted in a manner allowing for an increase and decrease in separation and thus between a stack-guiding configuration and a stack compressing configuration.

According to embodiments, a sheet post-processing apparatus includes a processing tray, a vertical alignment section, a horizontal alignment section and a controller. The controller is configured to control the horizontal alignment section to shift the sheet to a first alignment position a predetermined distance from the center of the processing tray in the sheet width direction, control the horizontal alignment section to align the sheet in the sheet width direction at the first alignment position, and control the vertical alignment section to align the sheet in the conveying direction at the first alignment position, control the horizontal alignment section to realign the sheet at the first alignment position.

A multifunctional printer comprising a printer section, an auto-document feeder, a scanner section, and a finisher, wherein a finisher path leads from the auto-document feeder into the printer section and converges with a print path into a shared finisher path leading to the finisher, such that documents scanned with the auto-document feeder can be conveyed to the finisher such that it can perform a finishing operation on the documents.

The aligning device receives a sheet conveyed in a sheet conveyance direction in a stackable manner and aligns a position of the sheet in the sheet conveyance direction. The moving mechanism moves the sheet aligned by the aligning device in the sheet conveyance direction together with the aligning device. The controller selectively executes a first mode in which first post-processing is performed on the sheet and then second post-processing is performed on the sheet and a second mode in which the second post-processing is performed on the sheet without performing the first post-processing on the sheet. The controller, in response to a selection of the first mode or the second mode, causes the moving mechanism to adjust a position of the aligning device in the sheet conveyance direction before the aligning device receives the sheet as a target of the first post-processing or the second post-processing, respectively.

A sheet processing apparatus includes a stacking unit configured to stack a plurality of sheets, an alignment unit including a supporting portion on which the sheets are loaded, the alignment unit being configured to align positions of the sheets loaded on the supporting portion, and a bonding unit configured to bond the sheets loaded on the supporting portion to each other. The alignment unit is configured to align a position of the second sheet stack with the first sheet stack. The bonding unit is configured to heat and pressurize the second sheet stack aligned by the alignment unit such that sheets of the second sheet stack are bonded to each other with the adhesive and the first sheet stack and the second sheet stack are bonded to each other with the adhesive.

In a crimp-binding device, a sheet jam less occurs when binding processing is performed. A sheet crimp-binding device includes: a conveying path along which a sheet is conveyed in a predetermined conveying direction; a placing part on which the sheet conveyed along the conveying path is placed; a stack part provided at a location downstream from the placing part in the sheet conveying direction; a discharge unit that discharges the sheet from the placing part to the stack part; a shift unit that moves the sheet placed on a placing position on the placing part in a direction along a sheet surface and perpendicular to the sheet conveying direction; a crimp-binding unit that applies crimp-binding processing to sheets that have been moved in the direction perpendicular to the sheet conveying direction by the shift unit to a crimp-binding position; a recognition unit that recognizes count information of a sheet.

According to embodiments, a sheet post-processing apparatus includes a processing tray, a vertical alignment section, a horizontal alignment section and a controller. The controller is configured to control the horizontal alignment section to shift the sheet to a first alignment position a predetermined distance from the center of the processing tray in the sheet width direction, control the horizontal alignment section to align the sheet in the sheet width direction at the first alignment position, and control the vertical alignment section to align the sheet in the conveying direction at the first alignment position, control the horizontal alignment section to realign the sheet at the first alignment position.
