ABSTRACT:
A plurality of lead electrodes are connected to a strip-like heating resistor in parallel and at regular intervals so as to define a heating resistor section between the adjacent lead electrodes. The heating resistor section is supplied with a current across the lead electrodes connected on both sides thereof. According to this invention, one recording block is constructed of a plurality of such heating resistor sections, and the heating resistor sections are sequentially energized within each recording block. By performing a plurality of such energizing cycles within each recording block, dots corresponding to the respective heating resistor sections are recorded.
