(4) Mirror motor circuit
The mirror motor is a stepping motor. Its driver is IC113 constant-current chopper control IC (SLA7024). For control, the CPU outputs a drive
signal to IC113 to drive the mirror motor by 1-2 phase excitement.
The SPF motor and the mirror motor are switched with relays RY1 and RY2. The switching signal is SMSEL-. When SMSEL- is LOW, a current
flows through the SPF motor. When it is HIGH, a current flows through the mirror motor.
(5) Duplex motor circuit
The duplex motor is a stepping motor. Its driver is IC111 darlington-sink transistor driver IC (TD62064AP). For control, the CPU outputs a drive
signal to IC111 to drive the duplex motor by 1-2 phase excitement.
