Description
側面部に第2コンプライアンス部を設置した構成の好適例において、側面部は、流路基板の周縁に沿って第1面から突出する基礎部を含み、第2コンプライアンス部は、基礎部の表面を含む側面部の外壁面に設置される。以上の態様では、流路基板の周縁に沿って第1面から突出する基礎部の表面を含む側面部の外壁面に第2コンプライアンス部が設置されるから、例えば側面部が基礎部を含まない構成(例えば側面部の外壁面と流路基板の側端面との双方にわたり第2コンプライアンス部を設置した構成と比較して第2コンプライアンス部が強固に固定される。したがって、コンプライアンス部の接合部からのインクの漏出等の不具合の可能性を低減できるという利点がある。
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の好適な例示であり、図1に例示される通り、制御装置22と搬送機構24とキャリッジ26と複数の液体噴射ヘッド100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。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10は、第3実施形態の液体噴射ヘッド100の断面図である。第3実施形態の筐体部40は、図9に例示した第2実施形態と同様に2個の導入口43がX方向に配列され、液体貯留室SRの内壁面は傾斜面47(471,472)を包含する。図10に例示される通り、第3実施形態の液体噴射ヘッド100の筐体部40は、外壁面が流路基板32の第1面F1(X-Y平面)に対して傾斜した傾斜部49を包含する。具体的には、傾斜部49は、液体貯留室SRの傾斜面47に略平行な部分である。
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。
