As is well known, a compact cassette is made by molding a pair of upper and lower halves that make up the cassette housing in an opaque synthetic resin so that they cannot be seen through, and molding them in a transparent or translucent synthetic resin so that they can be seen through. A pair of upper and lower window covers are attached to each of the halves. However, in the past, a very small transparent window cover was simply attached to the center of the two halves, resulting in poor visibility into the cassette housing. Therefore, recently, a device has been commercially available in which the above-mentioned window covers are enlarged to improve the visibility inside the cassette case. However, in the commercially available compact cassette, the upper and lower parts of an aluminum die-cast frame are joined together by a pair of upper and lower halves formed from transparent acrylic plates, which also serve as upper and lower window covers, sandwiched in a sandwich-like manner. However, it had the following flaws.

In other words, the guide roller pin cannot be molded integrally with the half, so the guide roller pin is formed from a steel pin separate from the half, and the steel pin is press-fitted into the half, making assembly extremely difficult. It's a hassle. In addition, the friction boss cannot be molded integrally with the half, so a part of one side of the aluminum die-cast frame is widened, and the friction boss, which is integrally molded with the aluminum die-cast frame, is planted on that surface. Therefore, the aluminum die-cast frame The shape of the upper and lower surfaces becomes asymmetrical. However, since the aluminum die-cast frame is visible from the outside through the transparent upper and lower halves, if the shape of the upper and lower surfaces of the aluminum die-cast frame is asymmetrical, the upper and lower surfaces of the cassette case (so-called A/B planes) The design looks asymmetrical and the product value decreases. Furthermore, when looking through the transparent upper and lower halves, even the joining part with the aluminum die-cast frame (periphery of the cassette housing) can be seen, resulting in a low product value.
