Abstract

PURPOSE: To perform printing with positive printing cycles, by changing a driving pulse width of a pulse motor using a specified stage of the printing cycles.
CONSTITUTION: At a time t1 a coincidence circuit output is obtained, and after one shot of a reference pulse (OSC) is delayed by a delay circuit, from t2 to t3 two shots of OSC are applied to a solenoid, thereafter till one shot t4 of OSC a motor is held, so that from T2 to T3 an electric current is passed through the solenoid and during four pulses of T2 to T4 the pulse motor is stopped. At the same time a type wheel is stopped and during t2Wt3 a pulse signal is applied to the solenoid to perform printing. After the printing, when a restoring time t3Wt4 has passed, the type wheel starts the rotation again. After this type selection printing stage has been completed, the paper feeding stage starts, and the output of a counter is applied to a pulse motor controlling circuit to extend the driving pulse with to increase the torque and to feed the paper.
