【考案の詳細な説明】 〔産業上の利用分野〕 本考案はコンピュータの磁気テープやオーディオテープ
または写真のフィルムなどの表面に付着したゴミを除去
するためのテープクリーナに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a tape cleaner for removing dust adhering to the surface of a computer magnetic tape, audio tape or photographic film.
テープドライブ装置には、磁気テープ表面のゴミなどの
付着物を取り除くため、第2図に示すテープクリーナ10
を備えていた。このテープクリーナ10は単結晶サファイ
アやアルミナ、ジルコニアなどのセラミックからなる角
柱体であり、エッジ角60〜80°程度の鋭いクリーナエッ
ジ10aを有するものであった。The tape drive device has a tape cleaner 10 shown in FIG.
Was equipped with. This tape cleaner 10 was a prismatic body made of a ceramic such as single crystal sapphire, alumina or zirconia, and had a sharp cleaner edge 10a with an edge angle of about 60 to 80 °.
上記テープクリーナ10は、第2図に示すようにクリーナ
エッジ10aが一定の角度でテープTと摺動するように配
置され、テープTが矢印方向に送られると表面の付着物
がクリーナエッジ10aによって取りのぞかれるようにな
っていた。As shown in FIG. 2, the tape cleaner 10 is arranged so that the cleaner edge 10a slides on the tape T at a constant angle, and when the tape T is fed in the direction of the arrow, the deposits on the surface are removed by the cleaner edge 10a. It was supposed to be removed.
また、第3図に示すように正三角柱体のテープクリーナ
11に3ケ所のクリーナエッジ11aを形成したものも用い
られていた。Also, as shown in FIG. 3, a tape cleaner having a regular triangular prism shape.
The one in which three cleaner edges 11a were formed in 11 was also used.
ところが、上記の如き従来のテープクリーナ10,11は研
磨加工を行って鋭いクリーナエッジ10a,11aを形成する
際に微小なチッピングが生じることは避けられず、また
加工後の取扱時や使用時などにおいても、クリーナエッ
ジ10a,11aが鋭いエッジであるためチッピングを生じや
すかった。However, with the conventional tape cleaners 10 and 11 as described above, it is inevitable that minute chipping will occur when the sharp cleaner edges 10a and 11a are formed by polishing, and when handling or using after processing. Also in the above, since the cleaner edges 10a and 11a are sharp edges, chipping is likely to occur.
このようにクリーナエッジ10a,11aに微小なチッピング
を生じたテープクリーナ10,11を使用し続けると、チッ
ピングが次第に大きくなってゆき、クリーニング効果が
悪くなるだけでなく、遂にはテープ表面に傷をつけてし
まうという問題点があった。If you continue to use the tape cleaners 10 and 11 with minute chippings on the cleaner edges 10a and 11a in this way, the chipping will gradually increase, not only the cleaning effect will deteriorate, but finally the tape surface will be scratched. There was a problem of putting it on.
そのため、従来のテープクリーナ10,11はテープに傷を
つけないように比較的短期間の使用で新品と交換しなけ
ればならず手間のかかるものであった。Therefore, the conventional tape cleaners 10 and 11 have to be replaced with new ones for a relatively short period of time so as not to damage the tape, which is troublesome.
上記に鑑みて本考案は、テープクリーナのクリーナエッ
ジを曲率半径10〜25μmの微小な曲面としたものであ
る。In view of the above, the present invention provides the cleaner edge of the tape cleaner with a minute curved surface having a radius of curvature of 10 to 25 μm.
以下本考案実施例を具体的に説明する。 Embodiments of the present invention will be specifically described below.
第1図(a)に斜視図、第1図(b)に端面図を示すテープク
リーナ1はアルミナ、ジルコニアなどのセラミックから
成る角柱状体であり、1つの頂角部をクリーナエッジ1a
としている。このクリーナエッジ1aは微小な曲率半径R
の曲面としてあるため、研磨加工時や使用時等にチッピ
ングを生じにくい。The tape cleaner 1 shown in FIG. 1 (a) is a perspective view and FIG. 1 (b) is an end view. The tape cleaner 1 is a prismatic body made of ceramics such as alumina and zirconia. One vertex is a cleaner edge 1a.
I am trying. This cleaner edge 1a has a small radius of curvature R
Since it is a curved surface, chipping is unlikely to occur during polishing or during use.
上記クリーナエッジ1aの曲率半径Rの最適値を求めるた
めに、第1表に示すようなさまざまな曲率半径Rを有す

リーナの材質は純度99.7%、平均結晶粒径2μmのアル
ミナで、エッジ角は60°とし、それぞれ同一条件の下で
テープドライブ装置に組み込んで加速試験を行った。In order to obtain the optimum value of the radius of curvature R of the cleaner edge 1a, tape cleaners 1 having various radiuses of curvature R as shown in Table 1 were prototyped and tested. The tape cleaner was made of alumina having a purity of 99.7% and an average crystal grain size of 2 μm, and had an edge angle of 60 °. The tape cleaner was assembled in a tape drive device under the same conditions to perform an acceleration test.
それぞれ、クリーニング効果と、通常の使用に支承をき
たす程度の傷がテープに発生するまでの時間を調べた。
結果は第1表の通りである。The cleaning effect and the time until scratches on the tape that would cause damage to normal use were examined.
The results are shown in Table 1.
第1表よりNO.1のクリーナエッジ1aの曲率半径Rが5μ
mのものはクリーニング効果は優れているが、チッピン
グを生じやすいため比較的短時間の使用でテープに傷を
生じてしまった。逆にNO.5,6のクリーナエッジ1aの曲率
半径Rが35μm以上のものはチッピングを生じにくいた
め長時間テープに傷をつけることなく使用できるが、ク
リーニング効果に劣っていた。 From Table 1, the curvature radius R of the No. 1 cleaner edge 1a is 5μ.
The m-thick film had an excellent cleaning effect, but chipping was likely to occur, and the tape was scratched after a relatively short time of use. On the other hand, when the radius of curvature R of the cleaner edge 1a of NO.
これに対し、NO.2〜4のクリーナエッジ1aの曲率半径R
が10〜25μmのものはテープに傷が発生するまでの時間
が142〜172時間と長く、かつクリーニング効果も優れて
いた。On the other hand, the radius of curvature R of the cleaner edge 1a of No. 2 to 4
In the case of 10 to 25 μm, the time until the scratch on the tape was generated was 142 to 172 hours, and the cleaning effect was excellent.
次にクリーナエッジ1aの曲率半径Rを10μmとし、テー
プクリーナ1の材質をさまざまなセラミックに換えて、
上記と同様の試験を行った。結果は第2表の通りであ
る。Next, the curvature radius R of the cleaner edge 1a is set to 10 μm, the material of the tape cleaner 1 is changed to various ceramics,
The same test as above was performed. The results are shown in Table 2.
第2表より、NO.1、2のジルコニアから形成したもの
は、ジリコニア自体の強度が大きく、平均結晶粒径も0.
5μmと小さいことから耐チッピング性に優れ、テープ
に傷が生じるまでの時間を長くすることができた。 As shown in Table 2, those formed from zirconia of Nos. 1 and 2 have high strength of zirconia itself and an average grain size of 0.
Since it was as small as 5 μm, it was excellent in chipping resistance, and it was possible to lengthen the time until the tape was scratched.
また、NO.4のアルミナから成るものは平均結晶粒径が5
μmと大きいため耐チッピング性が悪く、テープにキズ

粒径が小さいほど優れていることから、上記実験結果よ
り、テープクリーナ1の平均結晶粒径は5μmより小さ
いものが優れていることがわかった。Moreover, the average crystal grain size of alumina made of NO.4 is 5
Since it was as large as μm, chipping resistance was poor and the time until scratches were formed on the tape was short. Since the smaller the crystal grain size, the better the chipping resistance, it was found from the above experimental results that the tape cleaner 1 having an average crystal grain size of less than 5 μm is superior.
以上の実施例では、第1図(a)(b)に示す形状のテープク
リーナ1についてのみ説明してきたが、第3図に示す正
三角柱体やその他の形状のものについても同様であるこ
とは言うまでもない。In the above embodiment, only the tape cleaner 1 having the shape shown in FIGS. 1 (a) and (b) has been described, but the same applies to the regular triangular prism shown in FIG. 3 and other shapes. Needless to say.

となく使用可能な高性能のテープクリーナを提供するこ
とができる。As described above, according to the present invention, since the cleaner edge of the tape cleaner has a minute curved surface with a radius of curvature of 10 to 25 μm, chipping of the cleaner edge is less likely to occur during polishing or during use. It is possible to provide a high-performance tape cleaner that can be used for a long time without damaging the tape while maintaining the tape cleaning effect.
