本考案は、磁気テープカセット、クリーニングテープカセット或いはビデオテ ープカセットなどのテープカセットに関するものである。 The present invention relates to a tape cassette such as a magnetic tape cassette, a cleaning tape cassette or a video tape cassette.
【０００２】[0002]
従来のテープカセットでは、ケース内にあるハブ間におけるテープ走行経路に テープを案内するためにテープガイドローラ或いは中空円筒状の固定テープガイ ドが立設され、磁気テープを案内してハブに巻回走行できるようにしてある。 In the conventional tape cassette, a tape guide roller or a hollow cylindrical fixed tape guide is installed upright to guide the tape in the tape traveling path between the hubs in the case, and the magnetic tape is guided to travel around the hub. I am able to do it.
【０００３】[0003]
ところが、従来のテープガイドは、テープガイドローラの場合には、ローラの 支承用ポールを取付ける軸受部を設け、これに支承用ポールを嵌挿して、該ポー ルにローラを嵌装する組立構造のため煩雑で部品点数も多く生産性があげられな い欠点があり、また円筒状のテープガイドを軸穴に圧入して固定するタイプでは 、テープガイドの圧入の片寄りが発生しやすく走行するテープダメージが大きい ばかりか、組立性にも前例と同様に制約ができて生産性も高められないし、さら に実体のガイドポールを立設すると、カセット匣体のケース肉厚を薄くする場合 には、ヒケが発生しやすく歪が大きく精度も出しにくく外観上の体裁を悪くして 商品価値も低下するし、ヒケ防止のために中空の円筒形状としたガイドポールで は金型強度が弱く金型のピンが倒れたり、折れたりして金型寿命が短くコスト高 となるなど問題があった。 本考案は、これら従来の欠点を排除し、テープガイドの配備が適確にできテー プ走行に対する信頼性と組立性とを著しく向上できカセット匣体を薄肉としても ヒケ防止と強度増大とを可能として加工もしやすく精度も出しやすい体裁良好で 、しかも固定ガイドポールタイプとガイドローラタイプとの両用に兼用して使用 できる汎用性のあるテープカセットを提供することを目的としたものである。 However, in the case of a tape guide roller, the conventional tape guide has an assembly structure in which a bearing portion for mounting the roller support pole is provided, and the support pole is fitted and inserted into the roller, and the roller is fitted into the pole. Therefore, there is a drawback that it is complicated and the number of parts is large and productivity cannot be improved.In the case of a type in which a cylindrical tape guide is press-fitted into the shaft hole and fixed, the tape guide tends to be biased to one side and the tape runs. Not only the damage is great, but also the ease of assembly can be restricted as in the previous example and the productivity cannot be improved, and if the actual guide pole is erected, the case thickness of the cassette case can be made thinner. Sinks are likely to occur, distortion is large, accuracy is difficult to obtain, the appearance is bad and the product value is reduced, and the mold strength is weak with a hollow cylindrical guide pole to prevent sinks. Or fallen mold pin is, is broken or to die life there has been such a problem becomes a shorter high cost. The present invention eliminates these drawbacks of the prior art, enables proper tape guide deployment, significantly improves tape traveling reliability and assembly performance, and is capable of preventing sink marks and increasing strength even when the cassette housing is thin. The purpose of the present invention is to provide a versatile tape cassette that is easy to process and has good appearance, and can be used as both a fixed guide pole type and a guide roller type.

本考案は、上ケースと下ケースとからなるカセット匣体内にテープを巻装した 一対のハブを回転可能に備え、該ハブ間に走行されるテープ走行経路に配備され るテープガイドをケース内に立設したテープカセットにおいて、前記テープガイ ドを断面略Ｕ字形のテープガイドポールとし、その円弧面がテープ接触面となる ようにケースと一体に成形したことを特徴とするテープカセットである。 The present invention rotatably includes a pair of hubs, each of which has a tape wound inside a cassette housing consisting of an upper case and a lower case, and has a tape guide disposed in a tape running path that runs between the hubs in the case. The tape cassette is characterized in that the tape guide is an upright tape guide pole having a substantially U-shaped cross section, and the tape guide pole is integrally formed with the case so that its arcuate surface serves as a tape contact surface.

ケース内部に回転自在の一対のハブ４，４に巻装されたテープ３は断面Ｕ字形 状のテープガイドポール５の円弧面５1 に接触案内されてカセットヘッド部側に 所定位置に張装され、ハブ４，４の回転でテープ３を一方では繰り出し他方には 巻込んで走行させて円滑で安定したテープ３の巻取り、巻戻しができるし、ケー スを薄肉としても成形時に樹脂の集中が避けられ、ヒケの発生を防止するし、断 面Ｕ字形のテープガイドポールとすることで金型加工が容易で精度をも上げるこ とができ成形時における樹脂流れを良好にし、残留歪をも小さくして離型性も良 好でケースの強度もあげることができる。またテープカセットの形態でテープガ イドローラを用いるタイプで使用したいときには、前記テープガイドポール５の ヘッド部側のものを折除し、これに近接して備えたテープガイドローラ支承用ピ ン６にテープガイドローラ１６を嵌装してテープ３の走行を所定位置で安定して 円滑に行うことができる。The tape 3 wound around a pair of rotatable hubs 4 and 4 inside the case is contacted and guided by the arcuate surface 5 1 of a tape guide pole 5 having a U-shaped cross section and is tensioned at a predetermined position on the cassette head side. By rotating the hubs 4 and 4, the tape 3 is fed out on one side and rolled up on the other side to run so that the tape 3 can be smoothly wound and rewound, and even if the case is thin, the resin is concentrated during molding. It is possible to avoid sink marks and prevent the occurrence of sink marks, and by using a U-shaped tape guide pole with a cut surface, mold processing is easy and accuracy can be improved, and the resin flow at the time of molding is improved and residual strain is eliminated. The mold releasability is good and the strength of the case can be increased. When it is desired to use the tape guide roller in the form of a tape guide in the form of a tape cassette, the tape guide pole 5 on the head side is cut off, and the tape guide roller support pin 6 provided close to the tape guide pole 5 is used to guide the tape guide. By mounting the roller 16, the tape 3 can be stably and smoothly run at a predetermined position.
