ることを特徴とする感熱記録装置。 In a thermal recording device, the thermal head support shaft supports the thermal head at one end at its center, and the other end of the thermal head support shaft extends slidably at right angles to the thermal head holding shaft that rotates the thermal head. The thermal head is fixedly provided on both sides of the head, and has stepped portions that abut the roller shaft of the platen roller in the axial direction of the thermal head support shaft, and the surface connecting the stepped portions on both sides is the center of the heating element of the thermal head. A guide plate is provided parallel to the thermal head, and a spring is fitted to the thermal head support shaft and acts in a direction such that the stepped portion of the guide plate is always brought into contact with the roller shaft of the platen roller. Features of thermal recording device.
