本発明は印刷装置に関し、特に通電転写記録原
理を用いた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 an impact printer using the electric transfer recording principle.
従来、この種の通電転写記録に用いるインクフ
イルムは、固形インクからなるため、その使用回
数は１回か、せいぜい数回が限度であつた。
Conventionally, since the ink film used in this type of electrical transfer recording is made of solid ink, it can only be used once, or at most several times.
この問題点を解決するため、インクキヤリア
に、絶縁性の支持体と導電層との積層体を用い、
支持体に多数の小孔を設け、孔内にインクを保持

び帰路電極の径路でもつて通電し、インクを発熱
させて吐出させる方式のものが開発された（特開
昭61−219660号参照）。 In order to solve this problem, we used a laminate of an insulating support and a conductive layer for the ink carrier.
A system was developed in which a support was provided with many small holes, ink was held in the holes, and a recording current was passed through the paths of the recording electrode, ink, conductive layer, and return electrode to generate heat and eject the ink. (Refer to Japanese Patent Application Laid-Open No. 61-219660).
上記方式によるときには、孔内にインクを補給
することによつて、インクキヤリアを繰返し使用
することができる。
When using the above method, the ink carrier can be used repeatedly by replenishing ink into the hole.
ところが、インクフイルムである支持体は絶縁
体であり、導電層は発熱源とならない程度に抵抗
値が制御されており、この導電層は、インクの保
持には直接関与しないが、記録電流の通電電流経
路の一部になるものとして欠かすことはできな
い。 However, the support, which is an ink film, is an insulator, and the conductive layer has a controlled resistance value to the extent that it does not become a heat source. Although this conductive layer is not directly involved in holding the ink, it is responsible for the conduction of recording current. It is indispensable as a part of the current path.
したがつて、支持体と導電層とが積層一体化さ
れたものでは支持体と同長の導電層が必要であ
り、支持体が廃棄されるときには導電層も一緒に
廃棄されることになる。 Therefore, in the case where the support and the conductive layer are integrated into one layer, the conductive layer is required to have the same length as the support, and when the support is discarded, the conductive layer is also discarded.

In order to achieve the above object, the current transfer recording apparatus according to the present invention has a combination of a base film and an ink film, and records by generating heat in the base film to cause ink filled in the ink film to scatter and adhere to a recording medium. The base film is a laminate of a current-carrying layer and a conductive layer, and the current-carrying layer side is brought into contact with a needle electrode and a return electrode, and the current-carrying layer is a layer capable of generating heat. The conductive layer is a layer with negligible resistance, and the ink film has many small holes that are filled with ink, and at least a part of the film is in contact with the needle electrode.

The ink film and the base film are overlapped, the back of the base film is pressed with a needle electrode, the small holes of the ink film are directed toward the recording medium, and the return electrode is brought into contact with a part of the back of the base film to apply voltage to the needle electrode. When applied, heat is generated at the interface between the current-carrying layer and the conductive layer, and the heat causes the ink in the small pores of the ink film to fly out, adhere to the recording medium, and perform recording. The base film only needs to be in contact with the ink film at least at the needle electrode portion, and the base film and the ink film can be driven independently.

It is. The current-carrying layer 1 is obtained by controlling the resistance value of a resin such as polyester, polycarbonate, or urethane containing conductive carbon or metal powder. In addition, it is also possible to make a metallic resistor by vapor deposition or sputtering of indium, tungsten, or the like. conductive layer 2

記録がなされる。 In the principle diagram of FIG. 1, when a voltage is applied to the needle electrode 4, a current flows through the current-carrying layer 1 to the conductive layer 2 as shown, and returns to the return electrode 5 through the conductive layer. The contact area of the return electrode 5 must be sufficiently resistive compared to that of the needle electrode 4. Then, heat is rapidly generated at the interface 3a due to the difference in resistance between the two layers 1 and 2, and the ink is heated on that surface, generating bubbles, the ink is ejected and adheres to the recording medium 8, and recording is performed.

As described above, according to the present invention, since the separate base film and ink film are used in a superimposed manner, by bringing the needle electrode into contact with the non-porous base film side, the needle electrode against the molten ink is removed. A configuration that does not require waterproofing can be easily realized, and holes can be easily formed in the ink film. Further, according to the present invention, only one of the base film or the ink film can be replaced when the other deteriorates or is damaged, and the feeding speed of both films is made different so that the length of the ink film is shorter than the length of the ink film. A base film can be used, and an endless base film can be used in combination with an ink film.
