ABSTRACT:
Apparatus for adapting a common dc motor for use in a typewriter to drive the ribbon lift and advance functions. The motor is coupled by means of a set of gears to a shaft on which are mounted the ribbon advance gear and ribbon lift cams. Also mounted on the shaft is a slotted disk. As the motor and disk rotate, an optical sensor outputs a signal for each slot. A processor then computes the motor speed from the slot timing and issues modulated pulses to the motor to regulate its speed.
