8. Solenoid and clutch drive circuit
The solenoid and clutch drive circuit uses non-inversion transistor
arrays TD62318AP (IC09, 12) which turn on the solenoids and
clutches when the input signal is at L; and an inversion transistor
array M63823P (IC14) which turns on the solenoids and clutches
when the input signal is at H.
The expansion I/O PG port which controls the solenoids and clutches
is an open collector type which becomes high impedance when reset-
ting and H output. For this reason, to turn on the solenoids and
clutches at L level, the non-inversion type TD62318AP is used for
driving the PG port. On the other hand, the expansion I/O’s PC port is
at L level at resetting. For this reason, for driving the PC port, the
inversion type M63823P which turns on the solenoids and clutches at
H level is used.
9. Jogger motor drive circuit
The jogger motor control signal (JMA, A/, B. B/) from the expansion
I/O (IC11) is input into the driver IC SLA7024MT, to drive the jogger
stepping motor which aligns the sheets sideways.
The driving method is unipolar, 1-2 phase excitement, constant-volt-
age method.
Here is the driving pattern for the jogger motor.
