15. Stapler motor drive circuit
The control signal (STMA,B) from the expansion I/O expansion is
inputted through the driver TD62503F to the H driver circuit which
consists of a large-current driving transistors Q1
inputted through the driver TD62503F to the H driver circuit which
consists of a large-current driving transistors Q1
∼
4, thus driving the
staple motor which staples sheets.
The rotational direction (CW, CCW) of the staple motor is controlled
by signal logics STMA, STMB. The motor is braked to a stop at the
home position.
by signal logics STMA, STMB. The motor is braked to a stop at the
home position.
TD62503 (IC105) is a driver to drive Q1
∼
4. A delay circuit is com-
posed of peripheral resistors, capacitors, and diodes to prevent short
current from flowing into the H driver circuit which is formed by Q1
current from flowing into the H driver circuit which is formed by Q1
∼
4, when STMA and STMB are changed over.
The staple motor has a large rush current. It thus has a current limit
circuit consisting of a voltage comparator BA10393F (IC104) and
peripheral resistances and capacitors, to apply current limit at about
5.3A. To prevent the circuit from shorting or motor locking, a protec-
tive fuse (F2) is installed.

16. Stapler unit
The stapler unit (EH-524S: Max Co., Ltd.) staples up to 50 sheets of
80g/m
80g/m

paper. The unit consists of a driving DC motor (STM), home
position sensor (STHP), non-needle sensor (LSTS), cartridge sensor
(NCTS), and self-priming sensor which detects the stapling position of
needles (READY).
