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; Equipped with a tape winding mechanism that winds the printing tape, the printing tape is placed between the recording paper wound around the platen and the thermal head, and the mi-thermal head is pressed against the platen to print on the recording paper. In a thermal printer, a shaft that extends along the platen and is movable; a head pressure release mechanism that presses the thermal head against the platen and releases the pressure contact in conjunction with rotation of the shaft; A tape winding stop mechanism that stops the winding operation of the printing tape in conjunction with the rotation of the shaft; and a cassette shift mechanism that arranges the tape cassette at a plurality of height positions in conjunction with the rotation of the shaft. The cassette shift mechanism holds the tape cassette and includes 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, a pair of tape winding gears selectively engaged with the transmission gear, and these tape winding gears. and a pair of first wheels that rotate integrally with each other.
and the first pin gear, respectively,
and a pair of second pin gears mounted on the cassette holding means; and a pair of second pin gears mounted on the cassette holding means;
a pair of bobbins rotatable in conjunction with each of the pin gears; a pair of cores disposed within the tape cassette so as to be rotatable integrally with the bobbins, and around which the printing tape is wound; A thermal printer characterized by having
