ABSTRACT:
A thermal head, rotatably supported by a supporting shaft parallel to the shaft of a platen, is resiliently pressed by an elastic member, such as a sheet spring, and comes into contact with the platen. A pair of arm members are provided on either side of the platen, the arms having through holes which allow for rotatably fitting and supporting therein the platen shaft. A bar member for receiving a resilient force of the elastic member is linked to other ends of the arm members, passing across the space between the arm members. The bar member is relieved from contact with the elastic member by rotating at least one of the arm members around the platen shaft or by moving at least one end of the bar member in a direction away from the platen. In the latter case, a crank mechanism is used for changing the effective length of one of the arm members. The thermal printer is compact and light, has high printing reliability, and facilitates ease in maintenance and replacement of the thermal head.
