According to an embodiment, a sheet processing apparatus includes a first tray, a second tray, a discharge member, and a guide. The guide is provided to the second tray and changes a transport angle of sheets with respect to the second tray when the sheets are sent from a transport path toward the discharge member without passing through the first tray.

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.

A post-processing device includes a processing stacking portion that allows media to be stacked thereon; a binding member that performs a binding process on the media; a medium ejection portion on which the media ejected from the processing stacking portion are stacked and which moves upward and downward; and a pressing member that presses an upper surface of the media on the medium ejection portion. When media that have not been subjected to the binding process are stacked on the medium ejection portion, the pressing member and the media are brought into contact with each other. When media that have been subjected to the binding process are stacked on the medium ejection portion, the pressing member and the media are disposed further away from each other than when media that have not been subjected to the binding process are stacked on the medium ejection portion.

The guide is provided to the second tray and changes a transport angle of sheets with respect to the second tray when the sheets are sent from a transport path toward the discharge member without passing through the first tray.

A sheet stacking apparatus includes a conveying unit, a first support member configured to support a sheet, the first support member including a first supporting surface contacting an underside of a first end portion of the sheet in a direction orthogonal to a sheet conveying direction, a second support member configured to support the sheet, the second support member including a second supporting surface contacting an underside of a second end portion of the sheet, and a stacking unit. At least one of the first support member and the second support member is capable of moving between a first position that supports the sheet and a second position that does not support the sheet, and a length of the first support member is shorter than a length of the second support member in the sheet conveying direction.

In a sheet-processing apparatus, a controller controls a conveying guide to change over a sheet-conveying path of sheets that are ejected without stapling them to a sheet-processing conveying path based on predetermined sheet-conveying path selection information when judging that a non-stapling mode in which the sheet stapling processing is not performed on a first type of sheets follows a stapling mode in which the sheet-stapling processing is performed on a second type of sheets. The first type of sheets, which are not to be stapled, conveyed on the sheet-processing conveying path waits on a waiting portion in the non-processing mode while in the processing mode, a sheet-processing portion performs the sheet processing on the second type of sheets.

A post processing apparatus is attachable to an image forming apparatus. In a state in which a concavely curled recording material is placed on a second placement unit, when a plurality of the recording materials which are convexly curled are discharged to the second placement unit, a control unit causes a post processing unit to perform specified post processing on at least one recording material of the plurality of recording materials, causes a discharging unit to discharge the at least one recording material to the second placement unit, and after the discharge, causes the post processing unit to perform the specified post processing on the recording material or the recording materials of the plurality of recording materials other than the at least one recording material.

According to an embodiment, a sheet processing apparatus includes a first tray, a second tray, a discharge member, and a guide. The guide is provided to the second tray and changes a transport angle of sheets with respect to the second tray when the sheets are sent from a transport path toward the discharge member without passing through the first tray.
