- 第1方向にそれぞれ延び、且つ前記第1方向と直交する第2方向に互いに並んで配置された複数のノズル列と、前記複数のノズル列に属する複数のノズルにそれぞれ連通し、前記複数のノズルとともに前記第1方向に並ぶ複数の圧力室と、前記各ノズル列毎に対応して前記各圧力室にインクを分配供給する複数の共通インク室と、これら各共通インク室から前記圧力室を経由して前記ノズルに至るインク流通路とを有するキャビティユニットが備えられたインクジェットプリンタヘッドであって、
前記キャビティユニットは、前記第1方向に長尺形状を有しており、
前記キャビティユニットの前記ノズルが形成される前面と反対側の背面には、複数種類のインクにそれぞれ対応する複数のインク供給口が、前記第2方向に沿って並び且つ対応する共通インク室に連通するように形成され、
前記複数のインク供給口の箇所には、前記全てのインク供給口を覆う薄シート状のフィルタ体が配置され、
当該フィルタ体には、前記インク中の異物を取り除くためのろ過部が、前記各インク供給口毎に対応させて形成され、これら各ろ過部が、前記背面と直交する方向から見て、前記第1方向に長い長円形状に形成されていることを特徴とするインクジェットプリンタヘッド。 - 前記複数のインク供給口のうち少なくとも1つは、2以上の前記共通インク室に跨って連通され、このインク供給口に対応する前記ろ過部は、前記背面と直交する方向から見て、他のろ過部よりも大きく設定されていることを特徴とする請求項1に記載したインクジェットプリンタヘッド。
- 前記フィルタ体のろ過部は、前記共通インク室の延びる前記第1方向に長く形成され、前記ろ過部と同じ形状及び大きさで形成された前記インク供給口を経由して前記共通インク室と前記キャビティユニットにおける前記第1方向の一端部で連通するように配設されていることを特徴とする請求項1又は2に記載したインクジェットプリンタヘッド。
