More Information
Summary:The printing cost is minimized by reducing the number of parts of a thermal print head used for printers, for such as a facsimile, and the quality of a printed product is improved by preventing the warpage of the thermal print head. A base plate mounting surface of a heat radiation plate (2) is provided with a longitudinally extending mounting surface dividing groove (5). A head base plate (3) having a heating resistor (6) for printing and a circuit board (4) having a connector (10) for external connection are fixed on the base plate mounting surface. The two plates (3, 4) are arranged so as to be opposed to each other with the mounting surface dividing groove positioned therebetween. Terminal electrodes (8, 11) provided on groove-side edge portions of the head base plate and circuit board are connected together by a terminal lead (9). An edge portion of at least one of the head base plate and circuit board projects to a position above the mounting surface dividing groove and forms a projecting edge portion, which is held from the upper and lower sides thereof by one end portion (9a, 9b) of the terminal lead.
