2) Stapler unit oscillation position detection
The stapler unit home position is detected by the stapler unit home
position switch (MS4).
The stapler unit home position switch (MS4) detects that the stapler
unit is in the home position.
The stapling position is determined by the pulse number to drive the
stapler unit oscillation motor (M4).

3) Stapler unit oscillation motor control
a. Outline

The stapler unit oscillation motor (M4) control circuit is shown in
the figure below.
The stapler unit oscillation motor is a stepping motor of 4-phase
control. By controlling the outputs of pulse signals (A, A

∗

, B, B

∗

),

the stapler unit oscillation motor (M4) ON/OFF and its rotating
direction are switched.
The power supply circuit of the stapler oscillation motor (M4) is
provided with the stapler cover switch (MS2) and the fuse (ICP3).
The stapler cover switch cuts off the power supply circuit when the
stapler cover is opened. The fuse (ICP3) cuts off the power supply
circuit when an overcurrent flows through the circuit. The stapler
unit oscillation motor (M4) is stopped in that manner.

b. Operation

The microcomputer on the sorter controller PWB receives a com-
mand of the staple mode from the copier. The microcomputer (Q1)
sends the drive pulses (SPSWHA, SPSWHA

∗

, SPSWHB,

SPSWHB

∗

) to the driver circuit.

The motor driver circuit drives the stapler unit oscillation motor
(M4) according to the signal.
When the stapler unit oscillation motor is held, the output timing of
the pulse signals (A, A

∗

, B, B

∗

) is fixed.

(4) Paper holding

1) Outline
Paper holding is performed during stapling. The paper holding arm
presses paper by the stapler roller when the staple unit oscillates. At
the same time, the stapler unit bin supporting arm supports the bin
from the bottom to stable stapling operation.
