THERMAL HEAD AND TEMPERATURE CONTROL APPARATUS FOR PRINTER |
摘要 |
A thermal head for a printer includes a heating resistor temperature which is controlled by a temperature control apparatus. The temperature control apparatus senses the temperature of the heating resistor from a current flowing through the heating resistor and a temperature coefficient of the resistor. The temperature control apparatus includes a down-counter for decreasing an initial data corresponding to a current of the heating element when the heating element has a positive temperature coefficient. While, the temperature control apparatus includes an up-counter for increasing an initial data corresponding to a current of the heating element up to a full-count data when the heating element has a negative temperature coefficient.
