Abstract
A thermal head supporting mechanism for use on a thermal printer is disclosed. A thermal head cooperates with a platen supported on the body of the printer. A head frame hinged to the body of the printer supports the thermal head through a plurality of leaf springs connecting the head frame and the thermal head for enabling the thermal head to tilt with respect to the head frame. A pair of adjustment screws in the head frame operates through pressure springs upon the thermal head and adjustment of the screws adjusts the pressure of the thermal head and its parallel relationship with the platen. A control lever hinged to the body of the printer includes recesses which permit the head frame to be moved toward and away from the platen. An auxiliary roller is carried on the head frame by leaf springs and the auxiliary roller presses a printing medium against the platen.
