Description
かかる態様では、キャップのリブの当接領域の外側に基準穴を設ける場合、鋭角の角部に対応する一対の第1の曲線部分の外側には鈍角の角部に対応する一対の第2の曲線部分より大きなスペースが残るので、それぞれにつながる2つの直線部分をそれぞれを延長させた仮想線上の交点のうち、第2の交点よりも第1の交点に近い位置に、基準穴を有することにより固定板自体を大きくすることなく、基準穴を配置できる。また、基準穴はキャップのリブとの当接領域の外側にあるので、キャップ時に隙間が生じることもなく、当接領域の内側に設ける場合のように基準穴にインクが堆積することを防止することができる。なお、複数の直線部分には、第1の曲線部分と第2の曲線部分とにつながる直線部分、2つの第1の曲線部分につながる直線部分、及び、2つの第2の曲線部分につながる直線部分が含まれる。
かかる態様では、固定板自体を大きくすることなく、基準穴を配置した液体噴射ヘッドを複数個並設することにより、小型化を図った長尺ラインヘッドが実現できる。また基準穴はキャップのリブとの当接領域の外側にあるので、キャップ時に隙間が生じることもなく、当接領域の内側に設ける場合のように基準穴にインクが堆積することを防止することができ、液体噴射ヘッドの並設方向にワイピングする場合にも、仮に基準穴に堆積した液体があってもノズル開口へのワイピングに影響を与えることがない。
かかる態様では、小型化を図った液体噴射ヘッドを具備する液体噴射装置が実現できる。また、基準穴はキャップのリブとの当接領域の外側にあるので、キャップ時に隙間が生じることもなく、当接領域の内側に設ける場合のように基準穴にインクが堆積することを防止することができる。
かかる態様では、小型化を図った液体噴射ヘッドユニットを具備する液体噴射装置が実現できる。また、基準穴はキャップのリブとの当接領域の外側にあるので、キャップ時に隙間が生じることもなく、当接領域の内側に設ける場合のように基準穴にインクが堆積することを防止することができる。
(実施形態1)
図1は、本発明の実施形態1に係る液体噴射装置の一例であるインクジェット式記録装置の概略構成を示す斜視図である。
以上、本発明の一実施形態について説明したが、本発明の基本的な構成は上述したものに限定されるものではない。
