THERMAL HEAD AND ELECTRONIC EQUIPMENTS |
摘要 |
A thermal head is suitable for use in electronic equipments such as printers and the like and comprises a partially or entirely trapezoidal partial-glaze layer formed on the top of an insulation substrate at one edge, a resistive film layer formed on the partial-glaze layer, a pattern of common and discrete electrodes formed on the resistive film layer on the opposite sides of the partial-glaze layer except the area thereof that corresponds to the top of the partial-glaze layer, and a protective film layer formed to cover the resistive film layer and electrodes. In such a manner, a heating section is provided on the top of the trapezoidal partial-glaze layer. The heating section extends further upwards from the surrounding area. Unnecessary dispersion of pressure to the surrounding area other than the heating section can be avoided to improve the printing efficiency and speed. |
