Abstract

PURPOSE:To obtain a mist printer which enables to regulate ink droplet diameter and brings about a high quality printing by laminating a film with tiny holes and another film with smaller holes to form an ink film. CONSTITUTION:A serial printer is provided with an ink film 7 which is formed by lamination of a primary film 1 with many tiny holes 1a and a secondary film 2 with smaller holes, and the ink film is wound closely to a heat sensitive head 4. If the heat sensitive head 4 is applied with electricity, the ink in the holes 1 and 2 is suddenly heated to generate bubbles, and the ink flies to adhere to a recording medium 6, resulting in printing. Inasmuch as the ink film 7 moves relatively to the heat sensitive head 4, and moves through an ink supply dives 3, the ink is constantly supplied. As states above, many holes of the film are exposed to a single heat generating body, resulting in a change of ink droplets to become misty, the volume of the ink is controlled to enable a high quality printing.

が多く、これも信頼性に難があった。In addition, there are printers that constantly generate mist and form prints by balancing the electrostatic field. [Problems and points that the invention aims to solve] The conventional impact jet printers mentioned above tend to clog easily and have poor reliability. It's dim. Additionally, because the ink droplets are large, the recording medium must be specially processed to improve print quality. To prevent ink from drying out, unique mechanisms such as caps and cleaners were required on the nozzles. In addition, in mist printers, the surrounding area is wetted by mist, which upsets the balance of the electrostatic field, often resulting in unclear prints, which also poses a problem in reliability.

本発明は目づまりをなくし、インク滴径を制御し高信頼
性、高印字品質を得るようにしたミストプリンタを提供
するものである。The present invention provides a mist printer that eliminates clogging and controls the diameter of ink droplets to obtain high reliability and high print quality.

〔問題点を解決するための手段〕[Means for solving problems]

るバブルミストプリンタである。In the present invention, an ink film is formed by laminating a main film having many fine holes and a sub film having holes even finer than the holes in the main film, and an ink supply device is provided to supply ink to the ink film. This is a unique bubble mist printer.

〔実施例〕〔Example〕

次に本発明の一実施例について図面を参照して説明する
。Next, an embodiment of the present invention will be described with reference to the drawings.

第１図は本発明の一実施例であるシリアル型プリンタの
概念図である。FIG. 1 is a conceptual diagram of a serial type printer which is an embodiment of the present invention.

ことは従来のプリンタと同様である。An ink film 7 is formed by overlapping a main film 1α having many fine holes 1a and a film 2 having even finer holes, and this ink film 7 is brought into close contact with the thermal head 4 via an ink supply device 3. It is wrapped. Similar to conventional printers, a recording medium 6 is wound around the platen 5.

実施例において、感熱ヘッド４に通電されると、発熱体
が熱せられてインクフィルム７の数多くの孔１α、２ａ
のインクが発熱体界面で急激に熱せられることにより気
泡が発生し、インクが飛びだす。In the embodiment, when the thermal head 4 is energized, the heating element is heated and the numerous holes 1α, 2a of the ink film 7 are heated.
When the ink is rapidly heated at the interface of the heating element, bubbles are generated and the ink is ejected.

これはバブルジェットとして公知の原理である。This is the principle known as bubble jet.

飛びでたインクは記録媒体６に付着し印字が形成される

移動することにより、より効率的にインク供給ができる
。The ejected ink adheres to the recording medium 6 and a print is formed. Since the ink film 7 moves relative to the thermal head 4 and passes through the ink supply device 3, it is constantly replenished with ink. Furthermore, by moving each of the films 1 and 2 independently, ink can be supplied more efficiently.

従来のヘッドが使用できる。Ink films can be easily made by etching, electrohoming, etc. and their respective lords,
We can also make a secondary film together. A conventional head can be used as the thermal head 4.

インク剤については水性、油性いずれでもよく、沸点は
約１００°Ｃ〜数１００℃が良い。The ink agent may be either water-based or oil-based, and preferably has a boiling point of about 100°C to several 100°C.
