Abstract

PURPOSE: To bring performance of a both a printing head and a pulse motor into full play by changing the period of impressed pulses according to different printing steps in a printer wherein a pulse motor feeds a printing head.
CONSTITUTION: A first acceleration step is conducted in which input pulses ϕ1Wϕ4 start to be fed in at about 300pps, when a control signal M is at high level and a pulse motor PM exhibits its maximum driving torque. Then a printing step is started with pulses impressed at about 700pps, when the speed of the motor PM is the most stable and at a constant value determined by the maximum power of a wire dot head, the signal M is at low level, and the current flowing in the motor PM is restricted to 50W90%.
