Description
その開孔6Baに、カートリッジ受け12への接続により開放される開閉弁13Bが設けられている。この各開閉弁13Bは、開孔6Ba,6Baを開閉可能に閉塞する弁体13Baと、開孔6Baを閉じる方向に弁体13Baを付勢する板バネ13Bb(2つの弁体13Baに対し共通)とにより構成される。インクカートリッジ6Bからインク供給チューブ7Bへインクが供給されると、大気連通管11からインクカートリッジ6Bへ大気が導入され、インクカートリッジ6B内はほぼ大気圧に維持される。なお、2つの弁体13Ba,13Baに対する板バネ13Bb,13Bbを1つの板バネ部材で構成しているが、別々に設けることができるのはいうまでもない。
ト基材に対し、ノズル穴43のインクを噴射する側の開口43aが形成されたノズルプレート基材の表面に、ノズル穴43をマスクした後に撥水膜を形成して、そのノズルプレート基材の表面であって開口43aの周囲に対し複数の突出部51を形成するようにしているが、図6(a)(b)に示すように、インクを噴射するノズル穴43’が未加工のノズルプレート基材に対し、その未加工のノズル穴43’のインクを噴射する側の開口43’aとなる部分が形成されるノズルプレート基材の表面に撥水膜を形成した後に、前記開口43’aとなる部分の周囲に複数の突出部51を形成した後に、複数のノズル穴43’を貫通形成するようにしてもよいのはもちろんである。
されるものではなく、ノズル面41Aaの撥水膜に記録用紙が直接に接触しにくくする形状であればよく、また、各突出部は同じ形状や大きさでなくてもよい。
るが、圧電方式のもの以外に、静電気あるいは電気発熱素子によって噴射動作をするものも使用することができる。
