ABSTRACT:
A thermal recording head device and a method for operating a thermal recording head device in which a video signal representing an entire line of dots to be printed is simultaneously stored. The thermal recording head itself is composed of a belt-shaped resistive member having leads arranged in first and second groups of leads extending alternately therefrom. The leads of the first group are alternatingly connected to a power supply terminal while synchronously therewith bits of a video signal are alternately gated to control corresponding switching elements connected between the leads of the second group and ground. AND-OR gates are employed to perform the alternating connection between the register in which the video signal is stored. Switching elements, composed of bipolar transistors, are connected between the leads of the second group of leads and ground.
