• and
• switching means for selecting either one of said first path and said second path,
• wherein the first and second path are both positioned downstream of said first tray in a same direction of sheet conveyance, said first path conveying said first sheet stack upward over a downstream portion of said first tray while said second path conveying said second sheet stack downward over said downstream portion,
• wherein said switching means steers, when said second path is selected, the sheet stack to said second path along a circumference of a conveyor roller located at a most downstream side of said first processing tray.

• a first and a second path both extending downstream of said first processing tray in a same direction of sheet conveyance and configured to convey a first and a second sheet stack output from said first processing tray, respectively, said first path conveying said first sheet stack upward over a downstream portion of said first processing tray as said first sheet stack is output from said first processing tray while said second path conveying said second sheet stack downward over said downstream portion as said second sheet stack is output from said first processing tray;
• and
• switching means for selecting either one of said first path and said second path,
• wherein said switching means steers, when said second path is selected, the sheet stack to said second path alone a circumference of a conveyor roller located at a most downstream side of said first processing tray.
