【発明の詳細な説明】
本発明はテーク、図形的・を記録するサーマルへラドに
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermal recorder for recording graphics.
従来より製法上大別すると厚膜形と薄膜形に分類される
。近年記録速度の高速化に伴い薄膜形のサーマルヘッド
が主流となりつつある。本発明も薄膜形に関し特に改良
されたサーマルヘッドを提供するものである。Traditionally, they have been broadly classified into thick film type and thin film type based on the manufacturing method. In recent years, as recording speeds have increased, thin-film thermal heads have become mainstream. The present invention also provides a particularly improved thermal head of the thin film type.
従来の薄膜形サーマルヘッドの断面描造を第１図に示す
。FIG. 1 shows a cross-sectional view of a conventional thin film thermal head.

4. It is formed in the jl of the dramatically worn layer 5.
然しなから従来の構成でｔユ発発熱かリード電極の厚み
分たけ凹状態となるためｈ１１録紙との接触が不光全で
あり記録紙への熱伝達効率か悪いという欠点があった。However, in the conventional configuration, heat is generated or the lead electrode becomes concave due to its thickness, so that the contact with the H11 recording paper is not perfect and the heat transfer efficiency to the recording paper is poor.
本発明の目的は上記欠点に鑑み発熱体から記録紙への熱

Next, the remaining aluminum film for forming the REET's output electrode 4 is pine-broken using a conventionally known method such as a fish tank or a sputter link. do. Next, lead′! 11 poles 2 are patterned by photo-etching and NANC methods.

In the above-mentioned embodiment, the manufacturing steps of the heating resistor 3, lead electrode 4, and alumina chemical film 6 are replaced. Since the thermal head constructed in this way has a flat heating resistor, the efficiency of heat transfer to the recorder is improved, the printing quality becomes questionable, and it is recognized that it has the effect of reducing power consumption and reducing sand.
