この考案はビデオカセット用テープリールの改良に係り
、長時間用および短時間用の２種類のテープリールにお
ける側面板を共通化して、コストダウンを図るとともに
、部品管理を簡素化することを目的とする。[Detailed description of the invention] This invention relates to the improvement of tape reels for video cassettes.The side plates of two types of tape reels, one for long-time use and one for short-time use, are made common, thereby reducing costs and improving parts management. Aims to simplify.
この種ビデオカセット用テープリールにおいては、磁気
テープの一端はハブの外周にテープ端係止片により係止
され、上記ハブに接合される側面板には、上気テープ端
係止片を側方からハブに脱着するための脱着孔が開設さ
れている。In this type of video cassette tape reel, one end of the magnetic tape is locked to the outer periphery of the hub by a tape end locking piece, and a side plate joined to the hub has an upper tape end locking piece attached to the side. A detachment hole is provided for attaching and detaching from the hub to the hub.
ところで、ビデ才力セント用テープリールＫをス使用時
間の違いにより長時間用と短時間用とがあり、それに応
じてハブの外径が前者では小さく、後者では大きくなっ
ている。By the way, there are two types of bidet tape reels K, one for long-time use and one for short-time use, depending on the length of time they are used, and accordingly, the outer diameter of the hub is smaller for the former and larger for the latter.
したがって、たとえば１２０分の長時間用と６０分の短
時間用とで＆亀・・ブ外周のテープ端係止片の設定位置
に合致する上記側面板の脱着孔の位置が異なり、長時間
用では側面板の内周部に、短時間用では外周部に位置す
る。Therefore, for example, the position of the removal hole on the side plate that matches the set position of the tape end locking piece on the outer periphery is different depending on whether it is used for a long time of 120 minutes or for a short time of 60 minutes. For short-term use, it is located on the inner circumference of the side plate, and for short-time use, it is located on the outer circumference.
そこで従来は、上記側面板を、その内周部に脱着孔が設
けられたものと、外周部に脱着孔が設けられたものとの
２種類用意し、長時間用では前者を小径の−・フに接合
し、短時間用では後者を大径のハブに接合してテープリ

するために、金型費用がかさみ、部品管理も繁雑になる
。Therefore, in the past, two types of side plates were prepared: one with a removable hole on the inner circumference and one with a removable hole on the outer circumference. For short-term use, the latter was joined to a large-diameter hub to create a tape reel.With this, two types of side plates are manufactured, which increases mold costs and complicates parts management. become.
この考案は上記従来の欠点を解消したもので、以下、こ
