ABSTRACT:
A thermal recording apparatus includes a roller for transferring thermosensitive recording paper, a thermal head including heating resistance elements, and a flat spring for biasing the thermal head to press against the thermosensitive recording paper on the roller. A cam is further provided in the thermal head, including a cam face along with contact members for keeping the thermal head at a distance from thermosensitive recording paper, and pushing the roller against the biasing force of the flat spring, under the condition where the heating resistance element of the thermal head is positioned on the line including the shaft of the roller and the contact point with the cam face.
