Description
図1は、本発明の第1実施形態に係る液体吐出装置10の部分的な構成図である。第1実施形態の液体吐出装置10は、液体の例示であるインクを印刷用紙等の媒体12に吐出するインクジェット方式の印刷装置である。図1に例示される通り、液体吐出装置10は、制御ユニット20と搬送機構22とキャリッジ24と液体吐出ユニット26とセンサー28と液体容器30とを具備する。液体容器30は、インクを貯留する容器(インクタンク)である。実際には複数色のインクが液体容器30に貯留されるが、以下の説明では便宜的に1種類のインクに着目する。第1実施形態の液体吐出装置10は、液体容器30に対するインクの事後的な補充が可能なCISS(Continuous Ink Supply System)方式の印刷装置である。ただし、液体吐出装置10に対して着脱可能なカートリッジを液体容器30として利用することも可能である。
本発明の第2実施形態を以下に説明する。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。
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。
