置。[Scope of Claim for Utility Model Registration] In a thermal head up/down device that presses the side surface of a heating resistor of a thermal head against the recording surface of thermal recording paper or separates it from the recording surface, a head support member on which the thermal head is mounted is a recording device. A fulcrum shaft that is rotatably held relative to the base and that, through its rotation, presses the thermal head against the recording surface of the recording paper and moves it away from the recording surface, one end of which is fixed to the surface of the head support member. a spring whose other end is fixed to a flange movable in a direction perpendicular to the surface of the head support member; a head upper and lower arm that converts the motion in a direction perpendicular to the surface of the flange and transmits it to the flange; an irreversible transmission means that transmits the rotation of the motor shaft to the rotating shaft via a worm gear and a worm wheel; After the thermal head is brought into contact with the recording surface by the movement, when applying pressure between the thermal head and the recording surface, the flange is further moved in the same direction to compress the spring. A thermal head up/down device characterized by:
