Description
図1は、第1の実施形態が適用されるインクジェットヘッドの分解斜視図である。
図18に第2の実施形態のインクジェットヘッド1を示す。第1の実施形態とアクチュエータ102の形状が異なっている。それ以外の部分は同じ構成となっている。
図19に第3の実施形態のインクジェットヘッド1を示す。第1の実施形態とアクチュエータ102の形状が異なっている。それ以外の部分は同じ構成となっている。
図20に第4の実施形態のインクジェットヘッド1の分解斜視図を示す。第1の実施形態と異なる点は、アクチュエータ102がノズル101と異なる位置にある。1つのインク圧力室201の円形断面の中心から離れた位置に、対応するノズル101の中心がある。インク圧力室201は、アクチュエータ102とノズル102を囲んでいる。ノズル101がアクチュエータ102の領域から離れた位置に設けられていること以外は、第1の実施形態と同じになっている。
図27に第6の実施形態のインクジェットヘッド1の分解斜視図を示す。第4の実施形態とインク圧力室201とアクチュエータ102の形状が異なっている。それ以外の部分は同じ構成となっている。
