【考案の詳細な説明】
この考案はカセットテープを使用するテープレコーダの
エージング試験に使用するテープに代わるダミーカセッ
トに関するものである。[Detailed Description of the Invention] This invention relates to a dummy cassette that replaces the tape used in aging tests of tape recorders that use cassette tapes.
従来テープレコーダのメカニズムのエージングにはエン
ドレステープが使用されていた。Conventionally, endless tape was used to age the mechanism of tape recorders.
しかしエージングは時間的に長時間にわたるので途中で
テープが切れたりする事故が多かった。However, because aging takes a long time, there were many accidents where the tape broke midway through.
本案はこのような問題を解決する目的で考案されたもの
で、内部のテープを除いたカセットの供給ハブと巻取ハ
ブとの間にベルトを設け、カセツトテープを装着した時
と同じ負荷がテープのメカニズムにか・るように構威し
たことを特徴とするものである。This project was devised to solve this problem.A belt is installed between the supply hub and take-up hub of the cassette, excluding the internal tape, so that the same load is applied to the tape as when the cassette tape is attached. It is characterized by being constructed in a manner similar to the mechanism of.
本案の一実施例について図面に従って説明する。An embodiment of the present invention will be described with reference to the drawings.
第１図は本案のダミーカセットの内部の詳細を示す図で
１はカセット、２は透明窓、３及び３′は消去ヘッド及
びビンチローラが位置する凹部、４は録音再生ヘッドが
位置する凹部である。Figure 1 is a diagram showing the details of the interior of the dummy cassette of the present invention, where 1 is the cassette, 2 is the transparent window, 3 and 3' are the recesses where the erasing head and vinyl roller are located, and 4 is the recess where the recording/playback head is located. be.
５′は巻取ハブ、５は供給ハブである。5' is a winding hub, and 5 is a supply hub.
６は両ハブ間に設けられたベルトでこれによって両ハブ
は連動して回転する。Reference numeral 6 denotes a belt provided between both hubs, which causes both hubs to rotate in conjunction with each other.
８及び８′は支点１０にそれぞれ一端を固定されスプリ
ング７及び７′にて両ハブに負荷をかけるため設けられ
た制動部材でこのスプリング７及び７′の付勢力を調整
することによって磁気テープが巻装されているカセット
を装着した時と同じ負荷がメカニズムにか・るようにす
るものである。Braking members 8 and 8' have one end fixed to the fulcrum 10, respectively, and are provided to apply a load to both hubs using springs 7 and 7'. By adjusting the biasing forces of the springs 7 and 7', the magnetic tape is rotated. This ensures that the same load is applied to the mechanism as when a wrapped cassette is installed.
尚制動部材はハブでなくベルト６に設けてもよいことは
勿論である。It goes without saying that the braking member may be provided on the belt 6 instead of the hub.
１１及び１１′は誤消去防止爪、９は固定ネジを示す。Reference numerals 11 and 11' indicate accidental erasure prevention claws, and reference numeral 9 indicates a fixing screw.
以上説明したように両ハブ間にベルト６を設け両ハブが
連動して回転し、磁気テープが巻装されたカセットを装
着して動作させた時と同じ負荷がメカニズム即ち供給軸
もしくは巻取軸に加わるように構或したので機械的に強
度の弱いエンドレステープなどを使用する必要がなくベ
ルト６にゴムやナイロン等の材質を使用することによっ
て半永久的に使用出来るメカニズムに対するエージング
用カセットテープに代わるダミーカセットを得る。As explained above, the belt 6 is provided between both hubs, and both hubs rotate in conjunction with each other, and the same load is applied to the mechanism, that is, the supply shaft or the take-up shaft, as when a cassette wound with magnetic tape is installed and operated. Since the belt 6 is constructed to be able to be used semi-permanently, there is no need to use mechanically weak endless tape, etc., and by using a material such as rubber or nylon, it can be used semi-permanently, replacing the aging cassette tape for the mechanism. Get a dummy cassette.
説明はカセットにて説明したがビテ゛イオ用のカートリ
ッジ等にも適用出来ることはいうまで゛もない。Although the explanation was given using a cassette, it goes without saying that it can also be applied to video cartridges, etc.
