Manual binding tray for sheet processing device

A sheet processing apparatus comprising:

• a transport path adapted to transport a sheet in a predetermined transport direction;
• a processing tray adapted to place the sheet transported from the transport path;
• a binding processing apparatus adapted to perform binding processing on sheets placed on the processing tray;
• a discharge opening adapted to discharge the sheet from the processing tray to outside an apparatus main body housing;
• a load tray provided on a downstream side of the processing tray in the transport direction to load sheets discharged from the discharge opening;
• neat alignment plates provided outside the main body housing to shift in a width direction orthogonal to the transport direction of the sheet loaded on the load tray and align opposite sides of the sheet;
• a sheet support surface provided in a different position adjacent to the processing tray in the width direction to support a sheet inserted from a manual feed opening provided outside the main body housing;
• a sheet regulation surface for regulating an end of a sheet supported on the sheet support surface;
• and
• a width-direction drive mechanism adapted to shift the neat alignment plates in the width direction,
• wherein the binding processing apparatus shifts to the processing tray and the sheet support surface, and is provided to be able to perform the binding processing on sheets placed on the processing tray or the sheet support surface, and
• the apparatus is further provided with a regulation member for regulating so that the neat alignment plates do not move beyond the sheet regulation surface in the width direction and are located at a side of the processing tray, during the binding processing for manually fed sheets on the sheet support surface.
