ABSTRACT:
A heat-sensitive printing machine is disclosed. The printing machine includes a platen upon which a heat-sensitive printing medium may be placed. A printing head has raised portions defining the indicia to be printed. A heater is provided for heating the printing head. A reciprocator moves the printing head between a first position remote from the platen and a printing position wherein the raised portions contact a heat-sensitive printing medium located on the platen. The printing head is connected to the reciprocator by a pair of leaf springs whose cross-section is sufficiently small that no more than about 20% of the heat in the printing head is conducted to the reciprocator through the leaf springs.
