Motor Control and Drive Circuit
.
The
motor is directly controlled by the CPU (4B), and is driven by a constant voltage.
The
motor has two functions (color select and ribbon feed). Switching between the two functions
is performed in accordance with the rotational direction (forward (C. W.) or reverse (C. W)) of the
motor.
Table 2-41 shows relationships between the various
motor controls.
