【発明の詳細な説明】
（産業上の利用分野）
本発明は、例えば、ＯＡ機器等のプリント用インクジェ
ットノズルの改良に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of an inkjet nozzle for printing in, for example, office automation equipment.
ＯＡｉ器のプリント用インクジェットノズルは、振動板

ク液案内装置により真直ぐに案内して用紙の所要位置に
点着してプリントするものである。The printing inkjet nozzle of the OAi device ejects a drop of ink from the ejection hole of the ink nozzle by one vibration action of the diaphragm, and guides it straight by an ink liquid guide device around the tip of the ejection hole. Printing is done by placing dots on the desired positions on the paper.
（発明が解決しようとする問題点）
ところで、ＯＡ機器等のプリント用インクジェットノズ
ルに於けるインクノズルには次のような機能が求められ
る。(Problems to be Solved by the Invention) Incidentally, the following functions are required of an ink nozzle in an inkjet nozzle for printing in OA equipment and the like.
■インク液の濡れが無いこと。■There is no wetting of the ink liquid.
■加工性及び加工精度が良いこと。■Good workability and processing accuracy.
■耐蝕性を有すること。■Have corrosion resistance.
■流体圧力に対して寸法変化が無いこと。■No dimensional changes due to fluid pressure.
この中でもとりわけインク液の濡れが、用紙にプリント
されるインク液の点着寸法、点着精度に重要な影響を与
えるので、インク液の濡れの無いインクノズルが要求さ
れている。Among these, the wetting of the ink liquid particularly has an important influence on the dot size and the dot accuracy of the ink liquid printed on the paper, so there is a demand for an ink nozzle that does not get wet with the ink liquid.
然るにこれまでのインクジェットノズルに於けるインク
ノズルには種々のものがあり、夫々一長一短がある。例
えば金めっきしたインクノズルは、耐蝕性を有するが、
流体圧力に弱い。超硬、宝石（サファイア、ルビー）、
セラミック等より成るインクノズルは、耐蝕性を有し、
流体圧力に対して寸法変化が無いが、加工がしにくく高
価である。However, there are various types of ink nozzles used in conventional inkjet nozzles, each of which has advantages and disadvantages. For example, gold-plated ink nozzles have corrosion resistance, but
Weak against fluid pressure. Carbide, gemstones (sapphire, ruby),
The ink nozzle made of ceramic etc. has corrosion resistance,
Although there is no dimensional change due to fluid pressure, it is difficult to process and expensive.
ステンレス鋼より成る通常のインクノズルは、加工性及
び加工精度は良いが、インク液の濡れが大である。A normal ink nozzle made of stainless steel has good workability and processing accuracy, but the ink liquid is heavily wetted.
インクノズルは、インク液の濡れが大きいと、噴出孔よ

ンク液は方向を変えて噴出したり、或いは噴出するイン
ク液が増えたりして、用紙にプリントされるインク液の
点着寸法、点着位置の精度に狂いが生じる。If the ink nozzle is highly wet with ink, when the ink is ejected from the ejection hole, droplets will remain attached to the tip of the ejection hole, so when the next ink is ejected, that ink will be removed. The ink may be ejected in a different direction, or the amount of ejected ink may increase, causing errors in the accuracy of the dot size and dot position of the ink liquid printed on the paper.
この為、インクノズルの先端面に窒化チタンの薄膜が被
覆されたインクジェットノズルが考えられているが、未
だインク液の濡れの問題は十分解消できない。For this reason, an inkjet nozzle in which the tip surface of the ink nozzle is coated with a thin film of titanium nitride has been considered, but the problem of ink liquid wetting has not yet been satisfactorily solved.
本発明は斯かる実情に鑑みなされたものであり、インク

せんとするものである。The present invention was made in view of the above circumstances, and it is an object of the present invention to provide an inkjet nozzle having an ink nozzle that does not get wet with ink liquid, has corrosion resistance, and has good workability and workability.

されて用紙の所要位置にプリントされるインク液の点着
寸法、点着位置の精度が高いものとなる。In this way, in the inkjet nozzle of the present invention, the tip surface of the metal ink nozzle is coated with a thin film of aluminum nitride, which improves the smoothness and specularity of the tip surface, prevents wetting of ink liquid, and prevents ejection. The ink liquid is guided straight by the ink liquid guide device around the front of the ejection hole, and the ink liquid is printed at a desired position on the paper with high precision in the spotting size and spotting position.
次に本発明のインクジェットノズルの具体的な実施例と
従来例について説明する。Next, specific examples and conventional examples of the inkjet nozzle of the present invention will be described.
