Thermal printer having heat radiation plate

摘要

A thermal printer includes a rotatable platen roller; an elongated thermal head which is movable toward or away from the platen roller; and a head supporting member having an elongated head supporting portion for supporting the thermal head formed at an end. A heat radiation plate through which heat generated from the thermal head during printing can escape is arranged between the thermal head and the head supporting portion, and the thermal head can be adjustably curved toward the platen roller via the heat radiation plate by an adjusting member arranged in the head supporting portion.
