従来のテープカセット或いはディスクカートリッジにおいて、上ケースと下ケ ースとを結合してケース匣体とするものでは、上下両ケースにそれぞれ結合筒体 を設けて、該結合筒体に取付ネジなどのビス止め或いは溶着などの固着手段でテ ープやディスクなどの記録媒体を収納してカセットとすることが知られている。 In a conventional tape cassette or disc cartridge in which the upper case and the lower case are combined to form a case case, a coupling cylinder is provided in each of the upper and lower cases, and a mounting screw or the like is attached to the coupling cylinder. It is known that a recording medium such as a tape or a disk is housed as a cassette by a fixing means such as screwing or welding.

この従来の上下ケースを一体結合するタイプのケース匣体のカセットでは、結 合筒体の突き合わせ接合面が、上下ケースの凹凸部で嵌合する形態が多いので、 ビス止め結合では組立性が極めて悪く、また溶着結合では溶着時に使用する超音 波にてズレが生じ溶着が安定しないし、結合不良や結合力のバラツキが多く、し かも位置決めずれや傾きが生じて精度よく結合できず信頼性の上でも品質管理上 問題があった。 本考案は、これら従来の欠点を排除し、上下ケースの結合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 位置決め精度を良好にして結合強度増大を可能として体裁良好で、生産性を大幅 に高められ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。 In this type of case-cassette cassette that integrally joins the upper and lower cases, the butt joint surface of the joining cylinders is often fitted with the convex and concave parts of the upper and lower cases, so the screw-fastened connection is extremely easy to assemble. In addition, in the case of welding, the ultrasonic waves used during welding cause a shift and the welding is not stable, and there are many bonding defects and variations in the bonding force. There was a problem in quality control even on the above. The present invention eliminates these conventional drawbacks, the upper and lower cases can be properly joined, the reliability against tape running and the assemblability can be significantly improved, and the positioning accuracy is improved and the joining strength is improved even if the cassette housing is thin. It is an object of the present invention to provide a tape cassette which can be increased in size and has a good appearance and which can significantly increase productivity.

Further, the center boss 20 provided in the case as required, and the other bosses may be provided with the positioning bosses 16 and the welding ribs 19 as described above to further increase the coupling strength and the torsional strength.
【００１１】 図５の実施例では、前記テープガイドポール５を折除し、支承用ピン６にガイ ドローラ２１を組込んで使用する例である。 図中、２２はパッド、２３はシールド板、２４はシートである。The embodiment shown in FIG. 5 is an example in which the tape guide pole 5 is broken and the guide roller 21 is incorporated in the support pin 6 for use. In the figure, 22 is a pad, 23 is a shield plate, and 24 is a sheet.

本考案は、結合筒体を設けた上ケースと下ケースとからなるカセット匣体内に 情報記録媒体を配備したカセットにおいて、前記結合筒体の突き合わせ接合面の 一方に溶着リブを設け、他方の結合筒体に位置決め用ボスを設けたことにより、 ケース匣体を構成する上下ケースの結合固着が精度よく適確にでき、溶着のズレ を防止し安定のある条件を出すことができカセット構成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精度と強度増大とを可能とし て体裁良好に生産することができる。 According to the present invention, in a cassette in which an information recording medium is provided in a cassette case including an upper case and a lower case provided with a coupling cylinder, a welding rib is provided on one of the butt joint surfaces of the coupling cylinder and the other joint is formed. By providing a positioning boss on the cylindrical body, the upper and lower cases that make up the case body can be joined and fixed accurately and accurately, welding deviation can be prevented, and stable conditions can be obtained. It is possible to remarkably improve the workability and the assemblability, and it is possible to increase the accuracy and the strength even if the cassette casing is made thin, and it is possible to produce a good appearance.
