Claims

[Scope of utility model registration request]

In a thermal printer that performs color printing by scanning and moving a thermal head having a heating element in pressure contact with recording paper, a carriage support shaft provided parallel to the scanning direction;
A carriage that is rotatable around this support shaft and is supported so as to be movable in the axial direction, and a thermal head unit that integrally carries the thermal head are provided with a support in the scanning direction on both sides (or carriages) of the thermal head unit. A pair of pivot shafts are provided parallel to and on the same axis, and a pair of pivot shafts are provided on the carriage (or on both sides of the thermal head unit), and are fitted to the pivot shafts so as to connect the thermal head unit to the thermal head unit. A pivot bearing supports the unit so as to be able to swing in a direction toward and away from the recording paper, and a pivot bearing supports the above-mentioned carriage so that the thermal head unit supported by the carriage can swing in a direction to bring the thermal head unit supported by the carriage into contact with the recording paper. 1. A thermal head support device comprising: biasing means for applying a bias.
