- 一端に送液部を有する容器に収納された液体を他端側から押子で押し出す送液装置において,該押子の押圧端に備えられた鍔部に対し他端側から当接自在となるよう移動自在に設けられ該鍔部への移動の際に前記鍔部に最初に斜めに当接し所定量だけ押子側へ押し付けることによって前記鍔部を乗り越えて把持する弾性付勢された鈎状フックを備えた移動子と、駆動モータにより回転するリードスクリューと、該リードスクリューに噛み合うナットを内包しリードスクリューの回転により直線移動されるキャリッジと、該キャリッジと前記移動子とを連結する連結手段と、前記送液部に接続された送液経路を閉塞するクランプと、送液開始の指令の初期に前記クランプにより送液経路を閉塞し続いて前記駆動モータにより前記移動子を前記押子の押圧端に移動させ前記鈎状フックを前記鍔部に自動把持させる制御回路とを備えたことを特徴とする送液装置。
- 前記移動子は,弾性付勢された鈎状フックを反付勢方向に移動させる手動解除手段を備えており、前記キャリッジは、前記リードスクリューに対する前記ナットの噛み合いを着脱するクラッチ機構を備えており、前記手動解除手段の解除操作に応じて前記クラッチ機構が作動し前記ナットと前記リードスクリューとの噛み合いが解放されることを特徴とする請求項1に記載の送液装置。
- 前記移動子が,押子の把持状態を検出する手段を備えたことを特徴とする請求項1に記載の送液装置。
