Abstract
PURPOSE:To control the flowing time or amplitude of a current flowing to a heater and to control the size of a dot to be printed by providing a heat transfer member to be overheated to an area equivalent to the quantity of heat generated from the heater above the heater. CONSTITUTION:Electrodes 4a, 4b are formed at a predetermined distance on a heating resistor 7, and the resistor 7 of the part exposed between the electrodes 4a and 4b becomes a heater 7a. Symbols C1, C2a, C3a, C2b, C3b, C4b denote heat transfer materials formed of aluminum. V-shaped cutouts 8 in which center lines between the materials C1 and C4a, C2b and C4b become valleys are formed on the upper face of a wear resistant film 6a formed to cover the materials C1-C4a, C2b-C4b. The films 5, 6a form protective films. In a thus formed thermal head, the size of a dot to be printed can be controlled by varying the flowing time or amplitude of a current flowing to the heater 7a.
