本実施の形態のインクジェットヘッド100は、パイプ状の容器2と、容器2から分岐した複数の流路15と、それぞれの流路15を介して容器2に接続された複数の圧力室9と、それぞれの圧力室9の出口側に繋がる流路17と、流路17の出口であるノズル13と、制御部18とを有する。
シリンダー3,4を移動(遥動)させる速度は、0.01~100mm/s程度であることが好ましい。特に0.11~10mm/s程度で使うことが好ましい。0.1mm/sより小さいと、細胞10が十分に動かない。100mm/sより大きいと、細胞10にダメージを与える。
バルブ12より細胞10を含む溶液1をパイプ状の容器2に注入する。バルブ12の後に、フィルターを用いてもよい。細胞サイズが20μm以下の場合には、フィルターは例えば20μm以下のフィルターを用いる。フィルターを用いることにより、20μm以下大きさの細胞を注入することが可能となる。
図2は、本発明の実施の形態2の遥動式のインクジェットヘッド200を示す。実施の形態1との相違点は、シリンダー3,4が同一方向の移動で拘束するためにジョイント30で結合されていることである。その他、説明しない事項は実施の形態1と同様である。
図3は実施の形態3のインクジェットヘッド300の断面図を示す。実施の形態1,2と異なり、実施の形態3では、パイプ状の容器41の内部に圧力室42に通ずる流路の上部にくぼみ40を設ける。すなわち、くぼみ40は、共通インク室である容器41から複数の圧力室42に通じる流路の入口部に設けられている。くぼみ40の形状は円錐、角錐、円柱、角柱のいずれであってもいい。下部へいくにしたがい、水平面での断面積が小さくなればよい。くぼみ40の形状は、円錐形状が望ましい。
図4A、図4Bは、実施の形態4のインクジェットヘッド400の断面図である。図4Bは、図4Aの線55のところでの断面図である。
図5は、本発明の実施の形態5におけるインクジェット装置600である。インクジェット装置600は、インクジェットヘッド500と、被対象物移動機構700とを含む。
