Abstract

PURPOSE:To obtain a mist printer without clogging and with an improved printing quality by closely contacting an ink film which has tiny holes filled with ink with a heat sensitive head through a cloth. CONSTITUTION:A serial printer is provided with an ink film 1 which has many tiny holes 1a filled with ink, and the film 1 is closely wound on a heat sensitive head 4 over a cloth 3 which passes by an ink supply device 2. If the heat sensitive head 4 is applied with an electricity, the ink which fills the cloth 3 and the holes 1a is suddenly heated to generate bubbles and the ink flies and adheres to a recording medium 6 on a platen 5, resulting in printing. The ink in the holes 1a of the ink film 1 is constantly supplemented by a capillary action of the cloth 3. By moving the cloth 3 and the ink film 1 relatively to the heat sensitive head 4 the ink may be more efficiently supplemented. Thus, a possible clogging may be precluded. In addition, because of a misty condition of droplets, an excessive supply of ink droplets is prevented to improve printing quality.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は印刷装置に関し、特にバブルジェットの原理を
応用したノンインパクトプリンタに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device, and particularly to a non-impact printer that applies the bubble jet principle.

〔従来の技術〕[Conventional technology]

従来、この種のインクジェットプリンタは１つのノズル
にて１ケのインク滴を形成する、いわゆるオンディマン
トインクジェットが主流であった。Conventionally, this type of inkjet printer has been mainly a so-called on-demand inkjet printer in which one nozzle forms one ink droplet.

その他にはたえずミストを発生させ静電界のバランスで
印字形成を行うものがあった。Others generate mist constantly and form prints by balancing the electrostatic field.

ミストプリンタでは、ミストにより周辺がぬれてしまっ
て静電界のバランスをくずし、印字が不鮮明になること
が多く、これも信頼性に難があった。The conventional inkjet printers mentioned above are amazing! 9
Since 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.

本発明は上述の欠点である目づ！９を印字品質について
解決したミストプリンタを提供するものである。The present invention does not solve the above-mentioned drawbacks! To provide a mist printer that solves the problem 9 regarding printing quality.

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

本発明は多数の細かい孔にインクを充填したインクフィ
ルムを感熱ヘッドに布を介して密着させ、かつインクフ
ィルムにインクを供給するインク供給器を設けたことを
特徴とするバブルミストプリンタである。The present invention is a bubble mist printer characterized in that an ink film filled with ink in a large number of fine holes is brought into close contact with a thermal head via a cloth, and an ink supply device is provided for supplying ink to the ink film.

〔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.

熱ヘッド４に密着するように巻き付ける。An ink film l having a large number of fine holes lα filled with ink is wrapped tightly around a thermal head 4 via a cloth 3 passed through an ink supply device 2.

。インク剤は水性、油性いずれでもよく沸点は約り００
℃〜数１００℃がよい。In the embodiment, when electricity is applied to the thermal head 4, the heating element is heated, and the ink filled in the cloth 3 and the ink filled in the many fine holes 1a of the film l are rapidly heated, and bubbles are generated at the interface. Ink comes out and the platen 5
It adheres to the upper recording medium 6 and forms a print. This phenomenon in which air bubbles are generated and ink is ejected is a well-known fact known as bubble jet. Ink is constantly replenished into the holes lcL of the ink film 1 through the capillary action of the cloth 3. A cloth 3 and an ink film 1 are attached to the thermal head 4.
Ink can be replenished more efficiently by moving the ink relative to the ink. Holes of several microns to several hundred microns can be easily formed in the in-ta film 1 by electrohoming or etching. Fabric 3 should be made of thread as thin as possible. The conventional thermal head can be used as is. The ink can be either water-based or oil-based and has a boiling point of about 0.00
℃~several 100℃ is preferable.

本発明の原理を用いれば、ライン型プリンタにも容易に
応用できる。又、カラー化についても容易であることは
自明である。The principles of the present invention can be easily applied to line type printers. Furthermore, it is obvious that colorization is easy.

In addition, since the ink droplets are in a mist form, excessive ink droplets can be prevented and printing quality can be improved.
