Abstract
A plurality of electrodes are arranged alternately on both sides of a predetermined strip-like region of an insulated substrate, thus making up a thermal head with a plurality of heating resistor elements bridging the electrodes. A potential is selectively applied to the electrodes on one side of the strip-like region and those electrodes adjacent thereto on the other side of the region thereby to energize the heating resistor elements interposed between the particular electrodes. Heat thus generated is used to visually record information in accordance with electrical signals on the thermally responsive recording paper capable of being colored in response to heat.
