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 a lower end of the gap;

a processing tray having a slope where the sheet stack lands with the leading end first and slides down, the processing tray having matching rollers for matching the sheet stack in a vertical direction which is a paper conveying direction;

a wall at a lower side of the slope configured to catch the leading end of the sheet stack that slid down the slope; and

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

wherein the matching rollers serve as bundle conveying rollers for holding the sheets in a bundle after stapling and being taken out from the stapler,

wherein an alignment member provided above the processing tray includes a paddle.
