（α）発明の技術分野
本発明はインクジェットヘッドの製造方法に係り、特に
ヘッドのノズル孔をインク流路と連通して一体成形する
製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (α) Technical Field of the Invention The present invention relates to a method of manufacturing an inkjet head, and more particularly to a method of manufacturing an inkjet head in which nozzle holes of the head are communicated with an ink flow path and integrally formed.
インクジェットプリンタはその無騒音性と普通用紙を利
用できるという利点により最近急速に普及してきている
が、特に必要な時に必要量のインクを供給するオンデマ
ント方式は、不要インクの回収装置や高圧電源が不要で
附属機器も少ない点間
から経済的にも有利なため、各方面で開発実用化が進め
られている。Inkjet printers have recently become popular due to their noiseless properties and the ability to use plain paper, but the on-demand printers, which supply the required amount of ink when needed, require unnecessary ink collection equipment and high-voltage power supplies. Since it is economically advantageous since it requires no unnecessary equipment and requires few auxiliary equipment, its development and practical application are progressing in various fields.

インクジェットヘッド本体とを合成樹脂接着剤を使用し
て接着して製造されていた。<c> Conventional technology and problems Conventionally, inkjet heads for such printers have been manufactured using electroforming methods, etc. to form nozzle plates with minute nozzle holes, in addition to the inkjet head body equipped with ink flow channels. The nozzle plate and the inkjet head body are then bonded together using a synthetic resin adhesive.
しかし、この方法によれば接着する際、合成構造歩留り
も不安定で量産に適していない。However, according to this method, the yield of the composite structure is unstable when bonding, and it is not suitable for mass production.
またノズル孔が微細であるため、特にノズル孔ル板自体
の製造も難しい等の問題があった。Further, since the nozzle holes are minute, there are problems such as difficulty in manufacturing the nozzle hole plate itself.
そこでノズル孔とインク流路とを一体的に形成すること

れる。Therefore, it has been considered to form the nozzle hole and the ink flow path integrally, and one method is to form a groove pattern between the nozzle hole and the ink flow path by etching or electrical discharge machining on a predetermined metal plate. A method of integrally forming them at the same time is considered.

されるインク微小粒の飛見方向にばらつきを生じる問題
があり、実用化に至るものではなかった。However, when a groove pattern is formed by the etching method or electric discharge machining method as described above, the groove width is minute in the nozzle groove, so it is difficult to form the groove to a sufficient depth while maintaining the groove width. This is very difficult, and when a large number of such grooves are formed, the inner surface shape of each groove is irregular, resulting in variations in the flight direction of the ink particles ejected from the nozzle hole, making it difficult to put into practical use. It was not something that would lead to change.
