b. When the second last paper is passed, the rear edge plate (1) is

lowered and passed under the paper bundle (2) to the rear edge of
the paper bundle (3). Then the rear edge plate is raised. (HP
position)

c. When the last paper from the machine passes the direction switch

gate right, it lowers the gate.

d. The paper bundle is moved in the paper exit direction by the rear

edge plate.

e. The rear edge plate and the side guide plate are moved in the

paper guiding direction and the upper guide plate is lowered to
perform the last alignment. Then stapling is performed by the sta-
ple unit.

f.

After alignment and stapling by the stapler unit, the side guide
plate is loosened and the shutter is lowered. The paper is moved
to the paper exit roller by the rear edge plate, and discharged to
the offset tray by the paper exit roller.

This machine is composed of the paper exit unit and the alignment
unit. The paper exit unit includes the paper exit tray 1 and 2. The
paper exit tray 2 is provided with the offset function and the lift-up
function.

The alignment unit includes the paper transport section used for the
non-staple mode, the paper alignment section for the staple mode,
and the staple unit.

By rotating the main drive motor, the paper exit unit and the all trans-
port rollers of the alignment unit are driven.

The top of paper bundle on the tray is detected by the combination of
the lever and the photo sensor to judge paper full on Tray 1.

Lift-up motor

In order to discharge paper always at a fixed position regardless of
paper load on the tray 2, the lift-up motor is driven, the pulley is
rotated normally or in reverse, and the timing belt is driven to move
the tray 2 up and down.
