Claims

[Scope of utility model registration request]

A frame forming the main body, a platen around which recording paper is wound, and a carriage movable along the platen.
A thermal 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 printing according to the movement of the carriage. A thermal printer is equipped with a tape winding mechanism that winds a tape, and a printing chip is placed between a recording paper wound around a platen and a thermal head, and the thermal head is pressed against the platen to print on the recording paper. a shaft that extends along the platen and is rotatable; a head pressure release mechanism that presses the thermal head against the platen and releases the pressure contact in conjunction with the rotation of the shaft; and the shaft. a tape winding stop mechanism that stops the winding operation of the printing chip in conjunction with the rotation of the shaft; and a cassette that arranges the tape cassette at a plurality of height positions in conjunction with the rotation of the shaft. and a shift mechanism, and the tape winding mechanism includes:
a pair of first pin gears that are rotatable in accordance with the movement of the carriage; a pair of second pin gears that respectively engage with these first pin gears; a pair of rotatable bobbins; a pair of cores disposed within the tape cassette and rotatably integral with the bobbins, around which the printing tape is wound;
A thermal printer comprising a pair of clutch mechanisms respectively interposed between the second pin gear and the bobbin.
