ABSTRACT:
Disclosed is a method for driving a printer carrier. One power source is connected via a constant current circuit to the carrier motor. Data storing means stores the current command data corresponding to the acceleration, constant speed printing and deceleration of the carrier motor. According to the method, the current command data from the data storing means is latched in synchronism with a clock signal. The latched data is converted to a current reference voltage. The output current of the constant current drive circuit is varied in accordance with the current reference voltage. Changing the current command data as desired makes it possible to adjust freely the torque of the carrier motor for acceleration and deceleration on a constant voltage from one power source.
