リンタの印字装置。 A lead screw is disposed in the left-right direction of the thermal printer, the lead screw is rotatable by a stepping motor, and a spiral groove is carved over substantially the entire length of the lead screw,
Furthermore, a carriage of an ink ribbon cartridge and a thermal head holder are loosely fitted into the lead screw so that they can slide together, and a guide pin is provided on the carriage, and the guide pin is connected to the lead screw. The thermal head holder is fitted with a pressure spring such as a leaf spring, and is pressed against the outer periphery of the lead screw so that the rotation of the stepping motor causes horizontal movement of the carriage and pressing operation of the thermal head. A printing device for a thermal printer characterized by the following features:
