An upper surface plate and a rear surface plate of the same shape are provided on the front and back surfaces of the cassette tape, respectively. A tape winding unit that is formed into a book cover shape by connecting side plates of an equivalent width, and a step is formed in the thickness of the cassette tape, and the thickness of the trapezoidal tape running unit that the magnetic head hits holds the reel. Thicker than the wall thickness of is shown. or,
The top plate and the back plate each have a double-layered structure, and the top plate and the back plate eliminate the thickness difference between the tape running part and the tape winding part of the cassette tape without gaps. A trapezoidal recess for holding the cassette tape is provided. Further, a hub stopper to be inserted into the hub hole of the reel of the cassette tape is provided on the upper surface plate in a protruding manner.

Further, the publication of Japanese Utility Model Publication No. 61-15016 discloses a "cassette tape case magazine". This "cassette tape case magazine" is a cassette tape magazine that has a flat rectangular tubular cross-section so that cassette tapes can be slid along the length of the cassette tape, and slides with respect to the flat opening of the cassette tape magazine. It is roughly configured from a slide plate that can be moved in and out. A regulation plate that supports the rear end of the cassette tape is provided at the back of the slide plate, and a lid that supports the front end of the cassette tape is provided at the front of the slide plate. A long hole extending in the longitudinal direction is formed at the center of the slide plate. On the inner wall surface of the cassette tape magazine where the slide plate slides,
The slide plate is provided with a protrusion protruding from the long hole and engaging with the inner edge of the long hole, and the inner surface of the cassette tape magazine facing the slide plate is engaged with the hub hole of the reel of the cassette tape.

The overall shape is easily distorted and the shape retention is insufficient, and the hub stopper may come off from the hub hole of the cassette tape due to the distortion of the cassette tape case. In addition, there is a problem that pride easily enters the inside of the cassette tape, and in order to absorb the step between the tape running portion and the tape winding portion of the cassette tape, the upper plate and the lower plate are doubled respectively. Since it is formed, there is also a problem that if it is made of plastic, the amount of plastic used is large and it is disadvantageous for environmental protection.

The cassette tape case of Japanese Utility Model Publication No. 61-15016 is expensive and bulky because it has a large number of plastic case parts and a complicated mechanism. Since it is inconvenient and made of plastic, there is a problem that it becomes plastic waste when the cassette tape case is no longer needed. Also, when the cassette tape is taken in and out, when the slide plate is put in and taken out from the flat opening of the cassette tape magazine, the pair of tongue-like projections rub the wall surface in the slide area of the hub hole of the cassette tape. However, there was a problem that the label was damaged.
