Abstract
PURPOSE: To obtain excellent print without contrast, by applying the stable voltage from the output transistor of the voltage regulating circuit to the heater of the printer head.
CONSTITUTION: The printer head 2 having the heaters 3aW3r are driven with pulse signal, and current is fed to the load head 2 via the voltage regulating circuit 9 from the power supply 8 in which the output voltage is not stable at the pulse period. Further, when the print operation is made with the head 2, that is, when the timing pulse is at high level, constant and stable reference voltage is obtained with the constant voltage diode 17, the regulated reference voltage is fed to the heaters 3aW 3r of the head 2 from the output transistor 10 of the circuit 9, and always constant current flows independently of the number of heaters in operation and excellent print without contrast can be obtained.
