For provisonal alignment paper (B4 or less), the rear edge plate
passes under a bundle of paper to reach the home position, and
stands by at a position slightly wider than the paper width (about
2mm) until the final alignment is performed toward the shutter.
After completion of the final alignment, the plate stops at a posi-
tion about 2mm from the edge similarly to the above, and stapling
is performed.

When a bundle of paper is discharged after stapling, the side
guide plate moves to a position so as not to interfere discharging
and to prevent against skew feeding of the bundle.
