(4-2) Ribbon motor driver
This is a driving circuit to drive the Ribbon Motor F and Ribbon Motor R (stepping motors).
The Ribbon Motor F is used to take up ribbon and the Ribbon Motor R is used to supply
ribbon.
The Ribbon Motor F/R is driven by the STEP_A/B signal sent from the CPU (IC1). The
rotational direction of the motor is determined by the DIR_A/B signal sent from the custom
IC (IC11). The strength of PF motor excitation (strong and weak) is switched by the
PDOWN signal sent from the CPU (IC1).
The motor drive circuits for the Ribbon Motor F and Ribbon Motor R are the same except
that the latter circuit has the motor rotational direction change function.
On the supply side, it is required to change the motor rotational direction depending on the
ribbon to be used, inside wound (ink-in) ribbon or outside wound (ink-out) ribbon. The
output of the Ribbon Winding Selection Switch is connected to IC702, and, by combining
this output signal with the DIR_B signal, the rotational direction of the Ribbon Motor R is
changed.
