Abstract

A sheet post-process apparatus of the present invention has a standby tray for stably dropping sheets of paper onto a processing tray, so that a pair of tray members for loading ejected sheets of paper is formed so as to project from the wall face of the standby tray and the loading face of sheets of paper is narrowed from the front end side of the sheets of paper toward the rear end side thereof.

Claims

1. A sheet handling apparatus comprising:

a pair of trays which supports a sheet stack in an inclined position with a leading end of the sheet stack down, the pair of trays being separated into right and left by a gap, the gap being widened toward a trailing end of the sheet stack, the sheet stack running off through lower end of the gap;

a processing tray having a slope where the sheet stack lands with the leading end first and slides down; and

a wall at a lower side of the slop configured to catch the leading end of the sheet stack slid down the slope.

2. The apparatus according to claim 1, further comprising:

a stapler which staples the sheets at the leading end side of the sheet stack on the processing tray.

3. The apparatus according to claim 1, wherein

the lower end of the gap is narrower than the sheet stack before the pair of trays spread in a direction across the gap, and the lower end of the gap is wider than the sheet stack after the pair of trays spread in the direction.
