Abstract
An improved thermal printhead in which the base plate is provided with a print-end surface which is narrower than the thickness of the base plate by forming an inclined surface along one of the corner edges of the end surface adjoining one of the major surfaces of the base plate. Alternatively, a narrower end surface serving as the print-end surface may be defined by forming inclined surfaces along the two corner edges of the original end surface of the base plate. In either case, by appropriate selection of the width of the print-end surface, a glaze layer of a suitable property can be formed over the print-end surface by making use of the surface tension of the glaze layer in its molten state. By chamfering the lateral edges of the corners along either lateral end of the print-end surface, the terminal printhead is provided with a smooth contact surface which has an optimum lateral width for favorable contact with print media and a high level of smoothness for favorable movement of the printhead relative to print media.
