Claims

[Scope of utility model registration request]

A frame forming a main body, a platen around which recording paper is wound, a carriage movable along the platen, a thermal head attached to the carriage and arranged to face the platen, and a thermal head mounted on the carriage. A tape cassette in which the printing tape is stored, a tape cassette in which the printing tape is stored, and a tape that winds the printing tape according to the movement of the carriage. In a thermal printer that is equipped with a winding mechanism, a printing tape is placed between a recording paper wound around a platen and a thermal head, and printing is performed on the recording paper by pressing the thermal head against the platen. a head pressure release mechanism that presses and releases the thermal head against the platen in conjunction with the rotation of the motor; and a tape winder that stops the winding operation of the printing tape in conjunction with the rotation of the motor. A stop mechanism and a cassette shift mechanism that arranges the tape cassette at a plurality of height positions in conjunction with the rotation of the motor, and the head pressure release mechanism holds the thermal head and rotates the thermal head. It has a holding means and a pressure contact cam that engages with the head holding means and is rotatable as the motor rotates, and rotates the head holding means in accordance with the rotation of the pressure contact cam.
