Claims

[Scope of utility model registration request]

Seven frames forming the main body, a platen around which the recording paper is wound, and a carriage movable along the platen.
A boomal head mounted on the carriage and arranged to face the platen, a tape cassette arranged on the carriage and containing a printing tape containing a heat-melting material, and a tape cassette that is arranged on the carriage and prints according to the movement of the carriage. A thermal printer that is equipped with a tape winding mechanism that winds the tape, places the printing tape between the recording paper wound around the platen and the thermal head, and prints on the recording paper by pressing the thermal head against the platen. In,
a shaft extending along the platen and rotatable;
A head pressure contact release mechanism that presses the thermal head against the platen and releases the pressure contact in conjunction with the rotation of the shaft, and stops the winding operation of the printing tape in conjunction with the rotation of the shaft. a tape winding stop mechanism; a cassette shift mechanism that arranges the tape cassette at a plurality of height positions in conjunction with rotation of the shaft; the cassette shift mechanism holds the tape cassette; The tape winding mechanism has a cassette holding means rotatably attached to the carriage, and the tape winding mechanism includes a rack gear disposed along the platen, a transmission gear that is attachable to the rack gear, and a transmission gear.
