Method of making unit heads for divisonal-type thermal head.

摘要

A method is provided for making unit heads from a material head (10). The unit heads are used to constitute a divisional-type thermal head. The material head includes an elongate insulating substrate (11) carrying a longitudinal array of heating dot portions (13), and a protective layer (16) extending longitudinally of the material head to cover the array of heat dot portions. According to the method, the material head is cut along at least one cutting line (C) which extends transversely of the material head at a position between two adjacent heating dot portions, wherein the protective layer has cutouts (17a, 17b) which extend from the respective longitudinal edges (16a, 16b) of the protective layer toward the array of heating dot portions at the position of the cutting line.
