Description
図1は、本発明の第1実施形態に係るインクジェット方式の印刷装置10の部分的な構成図である。第1実施形態の印刷装置10は、液体の例示であるインクを印刷用紙等の媒体(噴射対象)12に噴射する液体噴射装置であり、制御装置22と搬送機構24と液体噴射モジュール26とを具備する。印刷装置10には、インクを貯留する液体容器(カートリッジ)14が装着される。
本発明の第2実施形態を説明する。なお、以下に例示する各形態において作用や機能が第1実施形態と同様である要素については、第1実施形態の説明で使用した符号を流用して各々の詳細な説明を適宜に省略する。
図9は、第3実施形態における圧電素子38の平面図である。第1実施形態では、平面視で各振動領域Q2からみてY方向の正側に位置する端部EB1と各振動領域Q2からみてY方向の負側に位置する端部EB2とにわたる第2電極層386を例示した。第3実施形態では、図9に例示される通り、第2電極層386の端部EB1および端部EB2が、各振動領域Q2のY方向における両端間に位置する。すなわち、Y方向の正側における各振動領域Q2の端部からみてY方向の負側に第2電極層386の端部EB1が位置し、Y方向の負側における各振動領域Q2の端部からみてY方向の正側に第2電極層386の端部EB2が位置する。各第1電極層382で規定される能動部が振動領域Q2の内側に位置する構成は第1実施形態と同様である。
以上に例示した各形態は多様に変形され得る。具体的な変形の態様を以下に例示する。以下の例示から任意に選択された2以上の態様は、相互に矛盾しない範囲で適宜に併合され得る。
