【発明の詳細な説明】 本発明は、熱印字ヘッドに関する。[Detailed description of the invention] The present invention relates to thermal printheads.
従来のこの種の熱印字ヘッドで特に中型、大型 。This type of conventional thermal print head is especially suitable for medium and large sizes.

っている。A heat sink becomes essential. As shown in FIG. 1, some thermal printing heads 1 have adhesives or mounting brackets 3.3 (4.4Vi mounting screws) attached to the top surface of the heat dissipation plate 2. In such a thermal printing head 1, it must be manufactured separately from the heat dissipation plate 2, which increases the manufacturing cost, requires additional parts such as mounting brackets 3, and also reduces the manufacturing process. Since there are a large number of them, the manufacturing cost becomes even higher.
本発明は、製造コストが安くて済むようにすることを目
的とし、このため熱印字ヘッドを放熱板と一体化するよ
うにしている。The present invention aims to reduce manufacturing costs, and for this purpose the thermal printing head is integrated with the heat dissipation plate.
以下、本発明を図面に示す各実施例に基づいて詳細に説

１０を構成することができる。FIG. 2 is a sectional view of the thermal print head according to this embodiment. This example describes a thermal print head based on thin film technology. Heat position head 10i-1 of this embodiment: iron,
A heat sink 11 made of aluminum or the like is provided. An insulating layer 12 is formed on the upper surface of the heat sink 11 to a predetermined thickness (preferably 5 to 70 microns) by sputtering or vacuum deposition in an inert gas atmosphere such as nitrogen gas. A heating element 13 made of tantalum, for example, is formed on the upper surface of this insulating layer 12 using a method similar to that described above. After the conductor layer 14 is formed on the upper surface of this heating element 13 by the above method,
A portion of the conductor layer 14 corresponding to a desired portion of the heating element 13 is removed by photo-etching. A wear-resistant protective film 15 can be formed on the heating element 13 exposed by this removal by the above-described method. Therefore, according to this embodiment, the heat sink 11 has the role of a base supporting the heating element 13, and it is possible to configure the thermal print head 10 that is integrated with the heat sink 11.
第３図は他の実施例（こ係る熱印字ヘッドの断面図であ

, the conductor layer 14, the heating element 13, and the protective layer 15 are formed by thick film printing σ. In the case of this thick film method, the above-mentioned layers are formed by selecting materials that can be fired as desired.

Manufacturing costs can be significantly reduced by reducing the number of parts.
