Description
まず、はじめに、本発明を適用可能な一例のインクジェット記録ヘッドを搭載するインクジェット記録装置について、図6の斜視図を参照して説明する。
記録ヘッドH1001は、図7及び図8の斜視図でわかるように、着脱可能な6つのインクタンクH1900と共に記録ヘッドカートリッジH1000を構成する一構成要素である。各インクタンクH1900は、ブラック、ライトシアン、ライトマゼンタ、シアン、マゼンタ、イエローの各色のインクをそれぞれ収容している。この記録ヘッドH1001は、より詳細に以下に説明するように、電気信号に応じてインク中に膜沸騰を発生させるための熱エネルギーを生成する電気熱変換素子H1103(図11)を用いて記録を行う、いわゆるバブルジェット方式(商標)を採用したものである。その中でも特に、この記録ヘッドH1001は、電気熱変換素子H1103の形成面に対して垂直な方向にインクを吐出する、いわゆるサイドシュータ型の構成を有している。
図11は、記録素子ユニットH1002の構成要素である記録素子基板H1100の、構成を説明するために一部を破断して示す斜視図である。記録素子基板H1100は、例えば、厚さ0.5〜1mmのSi基板H1101を有し、薄膜形成技術を利用して作製されている。
タンクホルダーユニットH1550を構成するタンクホルダーH1500は、例えば、樹脂成形により形成される。タンクホルダーH1500は、インクタンクH1900を着脱自在に保持するものである。詳細には示さないが、このために、タンクホルダーH1500は、インクタンクH1900のタンク位置決めピンや係合用の爪がそれぞれ係合する穴を有しており、また、インク残量検知に使用するプリズムのための開口部も有している。また、記録ヘッドカートリッジH1000を、インクジェット記録装置本体のキャリッジ101の装着位置に案内するための装着ガイド、ヘッドセットレバーによりキャリッジ101に装着固定するための係合部、及びキャリッジ101の所定の装着位置に位置決めするための突き当て部もタンクホルダーH1500に備えることができる。
図9の矢印で示すように、記録ヘッドH1001は、記録ヘッドユニットH1002をタンクホルダーユニットH1003に結合することにより完成する。この結合においては、インク供給口部分に第4の接着剤が塗布され、記録素子ユニットH1002のインク供給口(第1のプレートH1200のインク供給口H1201)とタンクホルダーユニットH1003のインク供給口(流路形成部材H1600のインク供給口H1605)が連通するように、第1のプレートH1200と流路形成部材H1600が接着固定される。また、インク供給口部分以外にも記録素子ユニットH1002とタンクホルダーユニットH1003の接する数ヶ所の部分が、第5の接着剤で接着固定される。
記録ヘッドカートリッジH1000は、図12の矢印で示すように、記録ヘッドH1001に、6つのインクタンクH1900を装着することによって構成されている。これらのインクタンクH1900は、それぞれ独立して記録ヘッドH1001に対して着脱自在である。したがって、各インクタンクH1900を別々に交換可能であり、それによって、インクジェット記録装置における印刷のランニングコストが低減される。各インクタンクH1900が装着されると、前述のように、インクタンクH1900のインク供給口H1907と記録ヘッドH1001のジョイント部H1517が接続され、各インクタンクH1901内の各色のインクが記録ヘッドH1001に供給される。
次に、本発明における重要な特徴点である、上述のような記録ヘッドH1001において、プラスチック材料から構成したタンクホルダーH1500と流路形成部材H1600を、レーザー光を用いて溶着接合する方法について、図1〜5を参照して説明する。なお、これらの図には、ブラック、イエロー、マゼンダ、シアンの4色のインク用の記録ヘッドの例を示す(各色用の部分を示す符号には、最後にb、y、m、cをそれぞれ付けている)が、便宜上、上述の記録ヘッドH1100と同様の部分には同一の符号を付している。レーザー光による接合のため、本実施例において、タンクホルダーH1500はレーザー光を吸収するプラスチックから形成され、流路形成部材H1600はレーザー光を透過するプラスチックから形成されている。
図14を参照して本発明の実施例2を説明する。同図において、実施例1と同様の部分については同一の符号を付している。本実施例のインクジェット記録ヘッドの全体構成などは、実施例1と同様であり、詳細な説明は省略する。
図15を参照して本発明の実施例3を説明する。同図において、実施例1と同様の部分については同一の符号を付している。本実施例のインクジェット記録ヘッドの全体構成などは、実施例1と同様であり、詳細な説明は省略する。
