［従来の技術］ 円筒形状部材の径の変化による内部体積の変化をインク
吐出の手段として用いるインクジェットヘッドとしては
、従来より、円筒形状形成に圧電性結晶を用いたいわゆ
るグールド型ヘッドが広く知られている。
［発明が解決しようとする課題］ 上記の如き従来技術において明らかに大きな課題となる
点は、いかにして圧電性結晶による円筒形状を製造する
かであり、さらに、いかにして歪を得るための電界印可
に必要な電極をこの円筒形の内壁面に形成するかという
点である。従来技術はこの点で製造困難であった。すな
わち歩留りを向上させ難く、多ノズルヘッドの構成が難
しいため高速印刷に遺した装置構成となり得なかった。
本発明はこうした従来技術の問題点を考慮して発明され
たもので、その目的とする所は、１ノズル当たりの構成
に必要な機構の簡略化により、多ノズルヘッドの構成を
容易とし、高速印刷に適した装置構成を実現することに
ある。
［課題を解決するための手段］ 本発明は、インク滴吐出のためのノズル上面のインク中
に配置した円筒形状あるいは、不完全な円筒形状の可動
壁面の内壁面あるいは外壁面に発熱層を設けた構成の印
刷ヘッドであり、前記発熱層の発熱に伴う壁面部材表面
の熱膨張により形状を変化しうる如く構成したことを特

［作用］ 本発明の上記構成によれば、ノズル上面に設けた円筒形
状を構成する部材の内壁が熱膨張した場合には内壁に囲
まれる体積は増加する。次に熱膨張状態から復帰する際
には、前述の体積増分は排除される。加熱部分が外壁側
に有っても熱歪・熱応力により円筒形状内部の体積が変
化するのは同様である。形状変化により排除された体積
の一部はノズルより吐出される。
［実施例］ 本発明のインクジェットへ・ソドを、本実施例では第５
