従来の技術 コンピューターやワードプロセッサーなどの端末機の画
像出力には種々の方法が使用されている。2. Description of the Related Art Various methods are used to output images from terminals such as computers and word processors.
それらのなかで装置が小型であり、低価格である点で記
録紙に直接画像を形成する方法が好適である。Among them, the method of forming an image directly on the recording paper is preferable because the apparatus is small and the price is low.
上記直接画像記録方法としてよく知られているものに

り、装置が小型であるが、ワイヤがリボンを叩く音を発
生したり、機械的強度を保つためにワイヤ径を小径にで
きないので画像密度が上がらず高解像のプリンターにす
るのが難しい。Well-known direct image recording methods include a wire dot method and an interjet method.
The former wire dot method is a method of stacking an ink ribbon coated with pressure-sensitive wax and recording paper and striking it with a metal wire.The device is small, but the sound of the wire striking the ribbon is generated and mechanical strength is reduced. Since the wire diameter cannot be reduced in order to maintain it, the image density does not increase and it is difficult to make a high resolution printer.

易い欠点を有している。On the other hand, in the case of the inkjet method, various methods have been proposed in principle, but the common disadvantage is that the ink discharge path of several tens of μm is used according to the size of the formed ink dot. It has a drawback that the discharge path is apt to be clogged due to the insoluble substance and mold contained in the ink, or the solidification of the ink.

という欠点を有する。On the other hand, recently, a direct recording method utilizing a discharge phenomenon has been proposed. In this method, a nozzle made of glass or the like is filled with a resin in which carbon black or the like is dispersed, a wax material, and the recording material is made to fly from the nozzle end by the energy generated by the discharge from the nozzle end. is there. Although this method has lower noise than the impact method, basically, in order to perform high-resolution image recording due to the need for nozzles, it is necessary to finely move the nozzles for scanning, and the apparatus is There are drawbacks that the size becomes large, the operation speed becomes low, and the problem of nozzle clogging cannot be avoided.

An object is to provide a direct image recording method superior to a jet.

のである。Means and Actions for Solving Problems According to the present invention, an electrode is provided on one side of a recording paper, and a solid recording material in which a colorant is dispersed is provided on the other side of the recording paper so as to face each other. The above problems are solved by an image recording method characterized in that a signal is applied to discharge the recording material through the recording paper, and the recording material at the discharge position is decomposed or melted and transferred to the recording paper to form an image. It was done.
以下、図面を参照して本発明の構成を説明する。第１図
は本発明の画像記録方法を実施する装置例の概略の構成
図である。記録紙１は２で示される方向に移動してい
る。記録紙の一方の側には、高電圧印加用の電極３が並
べられている。電極には４で示した高電圧印加用電源が
それぞれ接続されている。Hereinafter, the configuration of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram of an example of an apparatus for carrying out the image recording method of the present invention. The recording paper 1 is moving in the direction indicated by 2. Electrodes 3 for applying a high voltage are arranged on one side of the recording paper. The electrodes are connected to the high-voltage applying power sources indicated by 4.
記録紙１の他方の側には、表面にワックス、樹脂などに
カーボンブラック、顔料などの着色剤が分散されている
記録材料５が塗布されたローラ７が設けられている。こ
のローラ７の芯６は金属であり、接地されている。On the other side of the recording paper 1, there is provided a roller 7 having a surface coated with a recording material 5 in which a coloring agent such as carbon black or pigment is dispersed in wax or resin. The core 6 of the roller 7 is made of metal and is grounded.
このような配置下にて、記録電極３に放電を誘起するに
十分な高圧パルスを印加すると、記録紙の記録材料ロー
ラが設けられている面に於いて、記録材料の転移による
画素化現象を生ぜしめる事を本発明者らは見出した。When a high-voltage pulse sufficient to induce discharge is applied to the recording electrode 3 in such an arrangement, a pixelation phenomenon due to transfer of the recording material occurs on the surface of the recording paper on which the recording material roller is provided. The present inventors have found that it causes a problem.
かかる現象は、ガラスノズルなどに封じ込められた記録
材料を放電エネルギーにより分解吐出させる方法とは異
なり、記録紙を通して記録材料を電撃によって溶融分解
し、溶融分解を生じた位置にて記録材料を記録紙に転移
させる現象と解される。従って本発明方法に於いては記
録紙は単に最終画像の担体として機能するのみならず、
放電路としても機能する。This phenomenon is different from the method of decomposing and discharging the recording material enclosed in the glass nozzle or the like by discharge energy, and the recording material is melted and decomposed by electric shock through the recording paper, and the recording material is melted and decomposed at the position where the melting and decomposition occurs. It is understood that it is a phenomenon to transfer to. Therefore, in the method of the present invention, the recording paper not only functions as a carrier for the final image,
It also functions as a discharge path.
かかる画素化現象を生ずる場合、通常の紙である記録紙
は紙繊維間の空隙が放電路確保の為に機能している事が
判った。When such a pixelation phenomenon occurs, it has been found that in recording paper, which is normal paper, the voids between the paper fibers function to secure the discharge path.
従って、空隙率の低下に伴い放電を生じ難くなり、絶縁
性のフイルム、例えばマイラー（商品名）などの場合、
放電による画素形成は生じない。但し、コンピューター
用の出力用紙、複写用上質紙などではかかる画素形成を
生じうる事が判った。また放電電圧を高くしたり、空隙
率の小さな紙の場合には記録紙の放電部に小さなピンホ
ールを生ずる事があるが、数〜数10μｍの不定形の穴で
ある為、周囲に付着する記録材料に隠蔽されて肉眼では
見分ける事ができない。Therefore, as the porosity decreases, it becomes difficult for discharge to occur, and in the case of an insulating film such as Mylar (trade name),
Pixel formation due to discharge does not occur. However, it has been found that such pixel formation can occur in output paper for computers, quality paper for copying, and the like. Also, if the discharge voltage is high or if the paper has a small porosity, a small pinhole may occur in the discharge part of the recording paper, but since it is an irregular hole of several to several tens of μm, it adheres to the periphery. It is hidden by the recording material and invisible to the naked eye.
このような画素形成は記録材料ローラの表層で起こるの
で、記録材料ローラ上の記録材料が消費しつくされるま
で安定して動作する。Since such pixel formation occurs on the surface layer of the recording material roller, it operates stably until the recording material on the recording material roller is completely consumed.
本発明の方法では記録材料としては、放電のエネルギー
により分解、溶融（気化、昇華）する任意の材料を用い
る事ができる。In the method of the present invention, as the recording material, any material that decomposes and melts (vaporizes or sublimates) by the energy of discharge can be used.
分解し難し絶縁性高分子フイルムや黒化するだけの紙
（繊維）等を除き、金属（薄膜）を含め多くの材料が用
いられる。Many materials are used, including metal (thin film), except for insulating polymer film that is difficult to decompose and paper (fiber) that is only blackened.
それらのなかで、画像化する目的に特に適合するものは
感熱性の（比較的低温で溶融する）ワックスや熱溶融性
高分子樹脂であり、着色の為にカーボンブラック、顔
料、染料などを分散、溶融している事が好ましい。又、
放電を確実にし、放電路を電極下方に特定する為に記録
材料は抵抗性乃至は導電性である事が好ましい。Among them, heat-sensitive waxes (melting at relatively low temperatures) and heat-melting polymer resins are particularly suitable for the purpose of imaging, and carbon black, pigments, dyes, etc. are dispersed for coloring. It is preferable that they are melted. or,
The recording material is preferably resistive or conductive in order to ensure the discharge and specify the discharge path below the electrode.
かかる目的の為に、導電性カーボンブラックを分散した
り、顔料と同時に金属粉、CuIなどの抵抗調製剤を分散
する事が好ましい。For this purpose, it is preferable to disperse the conductive carbon black, or to disperse a resistance adjusting agent such as metal powder or CuI together with the pigment.
第１図では、記録材料ローラを接地した場合について説
明したがバイアス電圧を印加して記録電極に印加する電
圧を下げる事もできる。Although the case where the recording material roller is grounded has been described with reference to FIG. 1, the voltage applied to the recording electrode can be lowered by applying a bias voltage.
また、記録電極は第１図のように円形でなく、角形や薄
膜状でもよく、記録電極は記録紙と接していても、離れ
ていても良い。Further, the recording electrode may have a rectangular shape or a thin film shape instead of the circular shape as shown in FIG. 1, and the recording electrode may be in contact with or apart from the recording paper.
更に記録ローラには、芯材がなくても良く、又その形状
もローラに限らず例えばシート状やベルト状でもよい。Further, the recording roller may not have a core material, and the shape thereof is not limited to the roller and may be, for example, a sheet shape or a belt shape.
以下実施例により本発明の画像記録方法を説明する。The image recording method of the present invention will be described below with reference to examples.

The making is about 12 in a oil bath with a 40 mm x 40 mm aluminum "mold" that can be divided into two with an inner diameter of 30 mm
While heating to 0 ° C., a core material was placed in the center and carbon-dispersed wax was added and melted. After cooling to room temperature, the “die” was divided into two, and the recording roller was taken out to prepare.
