<p>PROBLEM TO BE SOLVED: To provide a thermal head capable of accurately outputting different heating temperatures in the identical scanning to a thermal medium representing different colors corresponding to the heating temperatures. SOLUTION: This thermal head comprises a heating body r0 for executing the heating in different energies, an additional resistor r1 connected to the heating body r0, a first switching means 1 for controlling the heating body r0 in an active condition or an inactive condition and a second switching means 2 for controlling the heating body r0 and additional resistor r1 in an active condition or an inactive condition. When controlling the heating body r0 in the first energy condition, the heating body r0 is controlled to generate the heat by the first switching means 1. When controlling the heating body r0 in the second energy condition, the heating body r0 and additional resistor r1 are controlled in the series connecting condition by the second switching means 2.</p> |
