Claims

[Claims for Utility Model Registration] A thermal head having at least the length of a printing line, fixed to the mounting bracket 7 on the back side, and having a plurality of resistance heating elements 10 provided on the front side over the length of the printing line. 1 and a platen roller 2 facing the thermal head 1, a printing paper is set between the thermal head 1 and the platen roller 2, and is pressed by a pressing member 5 via the mounting fitting 7. The thermal head 1
is pressed against the platen roller 2, and while the printing paper is transferred by the rotation of the platen roller 2,
In a thermal printer that prints by energizing the resistive heating element 10 of the thermal head 1, the length of the mounting bracket 7 is formed to be at least the length of the thermal head 1, and the length of the mounting bracket 7 is formed to be at least the length of the thermal head 1. A thermal head mounting mechanism characterized in that the thermal head is fixed at the center position of the thermal head.
