前記噴射ヘッドに当接して前記噴射口を取り囲む閉空間を形成するキャップと、
前記閉空間に負圧を印加することにより、前記噴射口から前記流体を吸い出す吸引ポンプと、
前記閉空間を外部と連通させることにより、該閉空間の負圧を開放する負圧開放手段と、
前記噴射ヘッドと前記キャップとを当接、離間させる移動機構と、
を備え、
前記キャップは前記噴射ヘッドに当接して前記閉空間を形成する環状の第一部材と、
前記第一部材の内側に前記第一部材より高さの低い環状の第二部材と、を備え、
前記閉空間を外部と連通させた後に前記第一部材と前記第二部材とによって形成される開口部に負圧を作用させる負圧作用手段を備える流体噴射装置。 A fluid ejection device that ejects fluid from an ejection port provided in an ejection head,
A cap that abuts the ejection head and forms a closed space surrounding the ejection port;
A suction pump for sucking out the fluid from the ejection port by applying a negative pressure to the closed space;
Negative pressure release means for releasing the negative pressure of the closed space by communicating the closed space with the outside;
A moving mechanism for contacting and separating the ejection head and the cap;
With
The cap is in contact with the ejection head to form the closed space, and an annular first member;
An annular second member having a lower height than the first member inside the first member;
A fluid ejecting apparatus comprising negative pressure application means for applying a negative pressure to an opening formed by the first member and the second member after communicating the closed space with the outside.
前記第二部材の高さは、前記噴射ヘッドと前記キャップとが当接した状態において、前記噴射ヘッドに付着した前記液体と前記第二部材とが接する高さである流体噴射装置。 The height of the second member is a fluid ejecting apparatus in which the liquid attached to the ejecting head and the second member are in contact with each other in a state where the ejecting head and the cap are in contact with each other.
