Claims

[Scope of utility model registration request]

(1) In a transfer type serial dot type thermal printer, which prints by attaching a cassette of thermal transfer film to the head mounting part with a thermal head attached, and printing while moving from side to side with the thermal head, it is placed parallel to the printing paper along a guide. The base part is slidable in the direction but held so as not to rotate around the guide; the base part is held slidable in the direction perpendicular to the printing paper; The present invention is characterized by comprising a head mounting section for switching between raising and lowering the thermal head and starting and stopping winding of the thermal transformer film, and at least one cam mechanism that slides the head mounting section. thermal printer.

(2) Utility Model Registration Scope of Claims In the thermal printer according to claim 1, the drive shaft and the driven shaft are configured to be fitted into the reel of a thermal transfer film cassette that is rotatably fixed to the head mounting portion. It consists of a shaft, a gear fixed to the lower end of the drive shaft, and a gear fixed to the base and constantly rotated by power applied from the outside, and the thermal head contacts the printing paper via a thermal transfer film. The thermal transfer film winding mechanism is configured such that a gear fixed to the drive shaft and a gear fixed to the base part mesh with each other when the head mounting part is moved to a certain position. thermal printer.

(3) Utility model registration Claims In the thermal printer according to claims 1 and 2, a gear that rotates together with a guide that holds the base part and can slide together with the base part in a direction parallel to the printing paper; a gear that is rotatably held in the base and is driven and rotated from the outside via the guide and the gear; a cam that is rotatably held in the base and integrated with the gear; and a cam that is fixed to the head mounting part and is A thermal printer characterized by having a cam mechanism consisting of a pawl engaged with a cam.

(4) In the thermal printer according to claims 1 and 2 of the utility model registration claims, a gear and a belt wheel respectively provided at both ends of a shaft rotatably fixed to the base portion, and the belt wheel. A thermal printer comprising a belt stretched over a position in contact with the printing paper, and comprising a power mechanism configured so that a gear provided on the shaft rotates when the base part slides in a direction parallel to the printing paper.
