Abstract
Description
図1は、本発明の実施形態に係るプリンタ1の要部を模式的に示す斜視図である。
図2は、ヘッド5の一部を示す分解斜視図である。なお、図2の紙面下方(z方向の負側)がメディア101側である。
複数のプレートは、プレート間に介在する接着剤67(図8(d)参照)によって互いに固定されている。そして、図4に示すように、複数のプレートには、余剰な接着剤67を逃がすために、複数の逃がし溝69が形成されている。
図8(a)〜図8(d)は、流路部材23の製造方法の一例を説明する模式的な断面図である。
ノズル39は、他の流路と比較してインクの吐出特性に与える影響が大きいため、他の流路よりも高い精度で形成する必要性が高い。エッチングによる加工精度は比較的低いため、ノズルプレート33を金属で構成する場合であっても、ノズル39は、例えば、パンチングで形成されたり、ノズルプレート33を電鋳により作製する際に、パターンニングされることで形成される。このような工程では、ノズル39を形成する際に、逃がし溝69を形成することは難しいため、ノズルプレート33には、逃がし溝69を形成しなくても良いように設計するのが好ましい。
図9は、変形例に係る流路部材223(吐出素子265)を示す、図4に相当する断面図である。
