Abstract
To increase the degree of radial and axial alignments between a thermal head bar and a platen roller without being affected by the precision of manufacture and assembling of a cover adapted to be opened or closed by carrying either the thermal head bar or the platen roller in a thermal recorder, the thermal head bar is mounted to the cover or a housing of with two linear small plays and two small rotational plays, while forks provided at opposite longitudinal ends of the thermal head bar and radial cams provided at opposite ends of the platen roller are engaged with one another to restrict a radical alignment of the thermal head bar and the platen roller, while the fork provided at least at one longitudinal end of the thermal head bar and an axial cam provided at a corresponding end of the platen roller are engaged with one another to restrict an axial alignment of the thermal head bar and the platen roller.
