Abstract
A thermal head in a thermal printer is biased by a plurality of springs which are provided between the thermal head and stopper of the movable shafts, respectively. The distances between the thermal head and the stoppers are commonly adjusted by a rotating shaft through gears fixed to the rotating shaft and worms formed on the movable shafts, thereby subtly adjusting the thermal head biasing force of the springs in accordance with the condition of a sheet to be used.
