この発明は、ノンインパクト記録装置に係り、と＜（、
インク粒子ｔ−噴出せしめるインクジェット記録装置の
記録ヘッドに用いられるインクジェット・ヘッドに関す
る。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a non-impact recording device.
The present invention relates to an inkjet head used in an inkjet recording apparatus that ejects ink particles.
活字式、ワイヤドツト式等のインパクトプリンタに比べ
、騒音が小さいことを利点としたインクジェット式ノン
インパクトプリンタ社最近火いく注目を浴びている。Inkjet type non-impact printers have been attracting a lot of attention recently because they have the advantage of being less noisy than type type, wire dot type, etc. impact printers.
インクジェット式記録は、ノズルよりインク粒子全記録
媒体に噴射して記録全行なうものである。In inkjet recording, all recording is performed by jetting ink particles from a nozzle onto the entire recording medium.
インクジェット式記録技術には、大別して２つの方式が
ある。１つはノズルよりインク粒子を連続して噴射させ
ておき、記録に使用するインク粒子のみを電気的手段で
偏向して記録媒体に衝突させその他の不必要なインク粒
子は、ガターにて回収する連続噴射式であり、もう１つ
の方式は、記録に必要な場合のみインク粒子をノズルよ
り噴射させるオンデマンド式である。これら２方式の中
で本発明に最も関係があるのは、オンデマンド式であシ
、とくく圧電素子の変形を利用する圧カバルス式記録ヘ
ッドである。Inkjet recording technology can be roughly divided into two types. One is to continuously eject ink particles from a nozzle, and only the ink particles used for recording are deflected by electrical means to collide with the recording medium, while other unnecessary ink particles are collected by a gutter. One is a continuous ejection type, and the other is an on-demand type, in which ink particles are ejected from a nozzle only when necessary for recording. Of these two systems, the one most relevant to the present invention is an on-demand recording head, in particular a piezocaval type recording head that utilizes the deformation of a piezoelectric element.

ズル先端に余分なインクがもれて付着すると、インク粒
子の飛行方向が不安定となり、記録停止後、乾燥して固
化した場合、目詰りの原因ともなる。FIG. 3 shows the recording principle of the pressure pulse type recording head. The ink is sent into the ink chamber 3 from the ink supply @1 and becomes the next ink.
This changes the volume of the piezoelectric element placed on one side of the ink chamber (by applying pressure more instantaneously, ink particles 5 are generated from the nozzle 4 and collided with the recording paper 6. If ink leaks and adheres, the flight direction of the ink particles becomes unstable, and if it dries and solidifies after recording is stopped, it may cause clogging.
この発明は上記欠点を解決するため罠成されたものであ
り、ノズルからのインクもれをすみやかに吸収するもれ
インク吸収のできるインクジェット・ヘッドを提供する
ことを目的とする。The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide an inkjet head that can quickly absorb ink leakage from a nozzle.
この発明はノズル先端にインク吸収体を取り付け、ノズ
ルからインクぎもれても直ちに吸収できるようにし、任
意の位置に設けた廃インク吸収機構まで、もれたインク
を導くインクガイドを配役することによシ、簡単な構造
のもれインク吸収機構を実現したインクジェット−ヘッ
ドである。This invention has an ink absorber attached to the tip of the nozzle so that even if ink leaks from the nozzle, it can be absorbed immediately, and an ink guide that guides the leaked ink to a waste ink absorption mechanism installed at an arbitrary position. This is an inkjet head that realizes a leakage ink absorbing mechanism with a simple structure.
この発明によれば、ノズルから余分なインクがこぼれて
も直ちに吸収されるので、インク粒子発生に悪影ｌ＃を
与えることがない。According to this invention, even if excess ink spills from the nozzle, it is immediately absorbed, so that there is no negative influence l# on the generation of ink particles.
また、記録ヘッド自体にインク吸収体を取り付けている
次めに、記録ヘッドが、どの位置にいてももれたインク
金吸収することができる。Furthermore, since the ink absorber is attached to the recording head itself, the recording head can absorb leaked ink no matter where it is positioned.
ノズルを複数配置する場合でも、インク吸収体からなる
共通な部材金、ノズル先端に取り付けることにより、記
録ヘッドの小型化が可能となる。Even when a plurality of nozzles are arranged, the recording head can be made smaller by attaching a common metal member made of an ink absorber to the tips of the nozzles.
以下、図面を参照してこの発明の詳細な説明する。 Hereinafter, the present invention will be described in detail with reference to the drawings.
第１図にこの発明によるインクジェット式記録装置の記
録ヘッドの一実施例を示す。FIG. 1 shows an embodiment of a recording head of an inkjet recording apparatus according to the present invention.
ノズル８よりこぼれ九インクは直ちにインク吸収体から

収板を４ｉたし念場合、インク吸収体からなるインクガ
イド１４ｆ：至て、廃インク吸収機構ｌＯに吸収される
。前記インク吸収板９及びインクガイド１４は、インク
室壁１３に直接固着されている。Ink spilled from the nozzle 8 is immediately absorbed by an ink absorbing plate 9 made of an ink absorber. If the ink reaches the same ink absorbing plate 4i, the ink guide 14f made of an ink absorber is absorbed into the waste ink absorbing mechanism IO. The ink absorption plate 9 and the ink guide 14 are directly fixed to the ink chamber wall 13.
もれたインクの大部分け、インク吸収板かインクガイド
中で乾燥し、インクの、′Ｉｋが大量の場合だけ廃イン
ク吸収機構に達する。Most of the leaked ink dries in the ink absorbing plate or ink guide, and only when the ink 'Ik is large, reaches the waste ink absorbing mechanism.
このため、記録ヘッドからインクがもれることはない。Therefore, ink does not leak from the recording head.

でも記録ヘッドは、大型化しない。In this case, the number of nozzles 15f:ff is arranged, the ink absorption plate 16, the ink guide 17, the waste ink absorption return 18ft
are sharing. Therefore, even if the number of nozzles increases, only one ink leak absorption mechanism is required. Therefore, even with multiple nozzles, the print head does not become large.
