ればならず、多針は難しかった。Conventionally, recording devices have been manufactured using various methods. A recording device using a discharge breakdown recording paper consists of a vapor deposited aluminum layer, a black layer, and a base paper layer.The vapor deposited aluminum layer of the discharge breakdown recording paper is grounded, and an electrode to which a voltage is applied is brought into contact with this vapor deposited aluminum layer. The vapor-deposited aluminum is removed by heating or discharge destruction to expose the underlying black layer and recording is performed. Therefore, in order to perform good writing, the writing electrodes are made so that the electrode needles 11 are exposed to ensure reliable contact as shown in FIG. 1A. Here, 12 is a fixing material made of resin, and 13 is a lead. In the case shown in Figure 1B, where the electrode needles are buried in resin and are not exposed (protruded), the area around the electrode needles 14 is destroyed by heat, etc., and the debris generated during recording is broken and the insulation between the electrodes is broken. It is damaged and cannot be written properly. For this reason, the protruding electrode needles had to be made of a strong material, and a thick and hard material had to be used, making it difficult to create multiple needles.

材料であるタルクを混ぜあわせた成型体を電極ヘッドの
固定材に用いたためである。These are hexagonal boron nitride, which has excellent properties such as lubricity, heat resistance, electrical insulation, abrasion resistance, and workability. This is because a molded body mixed with the material talc was used as a fixing material for the electrode head.
次に、六方晶窒化ホウ素とタルクの配合比を変えて前記

す。Next, the electrode head obtained by the method described above using a molded body containing hexagonal boron nitride and talc in the epoxy resin as a fixing material with a different blending ratio is mounted on a recording device using discharge breakdown recording paper. The results were evaluated by printing on discharge breakdown recording paper, and the optimum blending ratio of hexagonal boron nitride and talc was examined. Before that, an electrode head using a molded body with varying contents of hexagonal boron nitride and talc in the epoxy resin as a fixing material was attached to the recording device, and the results of evaluation as an electrode head are shown in Table 1. and shown in Table 2.
以下余白

かを評価、難燃性はUL規格94に準じたものでテスト
片の厚みを、%インチで評価した。In the margin table 1 and table 2 below, print quality is 5 as mentioned above.
The stability of the dot shape after printing 10,000 characters was evaluated. The degree of dust adhesion is determined by the degree of dirt on the tip of the electrode head after printing 50,000 characters. Hardness is an evaluation of whether printing can be done without damaging the discharge rupture recording paper when printing on the discharge rupture recording paper.Flame retardancy is based on UL standard 94, and the thickness of the test piece is measured in % inches. evaluated.
加工性は成型体の作りやすさ、および機械加工のしやす
さである。Workability refers to the ease of making a molded body and the ease of machining.
表1および表2から明らかなように、六方晶窒化ホウ素
の場合は20重量係から効果があシ、タルクの場合は3
0重量係から効果があった。As is clear from Tables 1 and 2, in the case of hexagonal boron nitride, the effect starts to decrease from 20% by weight, and in the case of talc, the effect starts from 30% by weight.
It was effective from the zero weight section.
六方晶窒化ホウ素は、前述したような優れた緒特性を有

六方晶窒化ホウ素とタルクを組み合わせることによシ、
特性、コスト共に満足する配合比を見い出すことにした
表3は1表1および表2と同様の項目のチェックを行な
い、それらの総合評価を示したものである。Although hexagonal boron nitride has the above-mentioned excellent properties, it is a very expensive material, making it expensive to use as an electrode head. On the other hand, although talc is an inexpensive material, it has slightly inferior properties to hexagonal boron nitride. Therefore, by combining hexagonal boron nitride and talc,
In order to find a blending ratio that satisfies both properties and cost, Table 3 shows the overall evaluation after checking the same items as in Tables 1 and 2.

ドとして評価することができなかった。If the total amount of hexagonal boron nitride and talc is less than 20% by weight, as mentioned in the conventional example, the area around the electrode will be destroyed, dust generated during recording will accumulate there, and the insulation between the electrodes will be damaged. However, it cannot be used as an electrode head due to deformation or disconnection. Further, the total amount of hexagonal boron nitride and talc could not be maintained as a molded body on a 95-weight plate, and it could not be evaluated as an electrode head.
以上のことから六方晶窒化ホウ素とタルクの合計量が2

が現われた。From the above, the total amount of hexagonal boron nitride and talc is 2
It is preferable to use 5 to 90% by weight of the molded body as a fixing material for the electrode head. However, when evaluating an electrode head using a molded body as a fixing material in which the content of hexagonal boron nitride is less than 6% by weight and the content of talc is within the above range of 20% by weight or more, Although the excellent properties of crystalline boron nitride were not utilized, the content of hexagonal crystalline boron nitride was reduced to 5.
When the weight ratio was exceeded, the effects of the characteristics of hexagonal boron nitride appeared.
すなわち、六方晶窒化ホウ素を少なくとも5重量係以上
含有し、かつ、六方晶窒化ホウ素とタルクの合計量が2
5〜90重量%の成型体を電極ヘッドの固定材として用

After laminating copper to a thickness of 15 .mu.m, striped electrodes (line spacing of 50 .mu.m, line width of 50 .mu.m) are formed by photoetching. Even when this electrode head is installed in a recording device using discharge breakdown recording paper and printing is performed, the same characteristics as in Example 2 are obtained. Further, the results of evaluating the blending ratio of hexagonal boron nitride and talc were also the same as in Example 1.

るという効果がある。In addition, conventionally, the lifespan was determined by the length of the protruding electrode needle, and the higher the resolution, the thinner the electrode needle became.
Unless the amount of protrusion of the electrode needles is shortened, the protruding electrode needles cannot be maintained, making it impossible to create an electrode head with high resolution and long life. Since the electrodes are buried or stacked, the electrodes do not need to be thin, and the length of the electrodes can be freely selected, resulting in an electrode head with high resolution and long life. Furthermore, by mixing hexagonal boron nitride with talc, an inexpensive electrode head can be obtained while maintaining the excellent properties of hexagonal boron nitride.
