Abstract
Description
図1は、第1実施形態に係る液体吐出装置100を例示する模式図である。第1実施形態の液体吐出装置100は、液体の例示であるインクを媒体12に吐出するインクジェット方式の記録装置である。媒体12は、典型的には記録用紙であるが、樹脂フィルムまたは布帛等の任意の材質の記録対象が媒体12として利用される。図1に例示される通り、液体吐出装置100には、インクを貯留する液体容器14が設置される。例えば液体吐出装置100に着脱可能なカートリッジ、可撓性のフィルムで形成された袋状のインクパック、またはインクを補充可能なインクタンクが液体容器14として利用される。
第2実施形態を説明する。なお、以下の各例示において機能が第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7は、第3実施形態に係る液体吐出ヘッド26の構成を例示する断面図である。図7に例示される通り、第3実施形態の液体吐出ヘッド26は、第2実施形態におけるノズル板46と緩衝体48とを板状部49に置換した構成である。板状部49は、流路基板32におけるZ2側の表面の全域にわたる平板材である。
以上に例示した各形態は多様に変形され得る。前述の各形態に適用され得る具体的な変形の態様を以下に例示する。なお、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。
