Can be driven by a belt that moves in the vertical direction. (H03) When a sheet set aligned on the edge-stitching compile tray is conveyed to the saddle-stitching compile tray as a sheet set, if the sheet size is constant, the sheet side edge of the saddle-stitching compile tray It is possible to omit the aligning device (eg tamper). Also,
Even if the sheet size is different, by providing a mechanism in the sheet set transport path to align the sheet transport position into the saddle stitching compile tray in the widthwise center according to the sheet size, the saddle stitching compile tray It is possible to omit the sheet side edge aligning device. Further, even when the saddle stapler is controlled to move, the sheet side edge aligning device of the saddle stitching compile tray can be omitted.

The sheet processing apparatus of the present invention described above can achieve the following effects (E01) to (E03). (E01) Since the compile tray for saddle stitching is fixed to the frame of the sheet processing apparatus by inclining it so as to be substantially vertical, the width of the sheet processing apparatus can be reduced. (E02) Since one sheet processing device can perform edge-stitching processing at the upper part and saddle-stitching processing at the lower part, one sheet processing device is sufficient even for edge-stitching and saddle-stitching work.
The width of the entire machine including the copying machine, the edge stitching device and the saddle stitching device can be reduced. (E03) Since the saddle-stitching compile tray is arranged so as to be steeply inclined, the position in the conveying direction of the carried-in sheet to the saddle-stitching compile tray is determined by the lower end of the sheet.
Therefore, it is easy to position the sheet in the saddle stitching compilation tray. Therefore, it is possible to easily position the sheet with the plurality of gates.
