Abstract

PURPOSE:To enhance an integration degree, to increase a speed and to simplify the title apparatus, by forming a material to be recorded from a conductive material and arranging a multistylus electrode and a return electrode in opposed relationship so as to hold the aforementioned material to be recorded therebetween. CONSTITUTION:Multistylus electrodes 13, 13'... are arranged on one surface side of a material 12 to be recorded so as to be brought into contact with the base layer 1b of an ink ribbon 1 and a return electrode 14 is arranged on the other surface side of the material 12 to be recorded. The material 12 to be recorded is formed from a conductive material such as a metal, a conductive resin or conductive rubber. Therefore, when pulse voltage is applied while continuous scanning is performed, a pulse current flows to the return electrode 14 through the conductive material 12 to be recorded from the connected multistylus electrodes 13 as shown by an arrow and, by this method, an ink layer 1a is liquefied or gasified by Joule heat generated by the resistance of the ink layer 1a of the ink ribbon 1 to be transferred to the material 12 to be recorded.

Description

[Detailed description of the invention] (1) Technical field The present invention relates to an electrical transfer recording device.

(2) Prior Art FIG. 2 shows a diagram of the principle of a conventional device of this type. Reference numeral 1 denotes an ink ribbon consisting of an ink layer 1a with low electrical resistance and a base layer 1b with high electrical resistance, and is arranged so that the ink layer 1a is in contact with a recording material (paper) 2. Reference numerals 3 and 4 denote a multi-stylus electrode (needle-shaped electrode) and a return electrode which are pressed against the base layer 1b of the ink ribbon 1.

In the recording apparatus described above, when a pulse voltage is applied while continuously scanning, a pulse current flows from the multi-stylus electrode 3 to the return electrode 4, and as a result, the ink layer 1a of the ink ribbon 1 is liquefied by Joule heat generated by the resistance. Alternatively, it is vaporized and transferred to the recording material 2.

By the way, in the case of the conventional device described above, the multi-stylus electrode 3 and the return electrode 4 are both arranged on one side of the recording material 2, so the device becomes bulky in order to achieve integration. There are drawbacks. Furthermore, it is necessary to keep the distance between the multi-stylus electrode 3 and the return electrode 4 constant, and when multi-stylus electrodes are used, there is a drawback that variations in the distance become a problem.

(3) Purpose It is an object of the present invention to provide an electrical transfer recording device that eliminates the drawbacks of the conventional devices and can achieve high integration, high speed, and simplification of the device.

(4) Structure In order to achieve the above object, the present invention uses a conductive material as a recording material, and arranges a multi-stylus electrode and a return electrode to face each other with the recording material sandwiched between them. This is characterized in that a current flows from the electrode to the return electrode via the recording material.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, 13.13', 13"13m are multi-stylus electrodes, and 14 is a return electrode. These image electrodes are arranged to face each other with the recording material 12 in between. That is, the multi-stylus electrodes 13.13'・
The return electrode 14 is arranged on one surface of the recording material 12 so as to be in contact with the base layer 1b of the ink ribbon 1, and the return electrode 14 is arranged on the other surface of the recording material 12. Also,
The recording material 12 has a current flowing through the multi-stylus electrode 13゜1.
3'... are made of a conductive material such as metal, conductive resin, or conductive rubber so as to flow from the material 12 to the return electrode 14.

Therefore, in the case of this embodiment apparatus, when a pulse voltage is applied while continuously scanning, the conductive recording material 12 is moved from the connected multi-stylus electrode 13 as shown by the arrow.
A pulse current flows through the return electrode 14 through the ink layer 1a, and as a result, Joule heat generated by the resistance of the ink layer 1a of the ink ribbon 1 liquefies or vaporizes the ink layer 1a, as in the past, and transfers to the recording material 12. It will be done.

In the embodiment, the multi-stylus electrode 13.1
Although four 3'... are shown, this is just an example of eight, and it goes without saying that a larger number may be arranged. Further, although the ink ribbon 1 is shown as a two-layer type consisting of an ink layer 1a and a base layer 1b, it may be a single-layer type without a base layer.

(5) Effects This invention has the above-mentioned configuration, and since only the multi-stylus electrode is disposed on one side of the recording material, it is easy to integrate, and moreover, when applied to, for example, a page printer. , it is possible to speed up printing and make it larger, and it is also possible to reduce the variation in the distance between the multi-stylus electrode and the return electrode compared to the conventional method (just press with a constant pressure), reducing density unevenness. On the other hand, since it is possible to reduce the distance between the two electrodes, it is possible to save power and labor, and in addition, there are many excellent effects such as simplifying the device.
