Abstract
Description
図1は、本発明の好適な形態に係る液体噴射装置100を例示する構成図である。本実施形態の液体噴射装置100は、液体の例示であるインクを媒体12に噴射するインクジェット方式の印刷装置である。媒体12は、典型的には印刷用紙であるが、樹脂フィルムまたは布帛等の任意の材質の印刷対象が媒体12として利用される。図1に例示される通り、液体噴射装置100には、インクを貯留する液体容器14が設置される。例えば液体噴射装置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。
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。
