ドの駆動装置。It has a shift register that reads the recorded on/off binary bit pattern by a shift lock, and during recording, the on/off binary bit pattern for the heat generating element is obtained from each stage of the shift register over the entire length of the head, and the heat generating element is generated. Strobes the power supply source so that the entire element can generate heat all at once according to the bit pattern, and also supplies a shift clock to the shift register during the rising, apex, and falling stages of this power strobe signal. A driving device for a thermal head, characterized in that the device is configured to continuously drive the thermal head.
