Claims

[Scope of utility model registration request]

An upper case made of opaque resin has a tape slack prevention wall on the tape running surface side and side walls on both sides.A transparent resin tape usage amount display window and tape remaining amount display window are provided on the upper surface of the upper case body. In a video cassette case where the upper case body is coated with a transparent resin near these windows, a gate for the opaque resin is provided on the tape running surface side wall for preventing tape slack and on the back side of the side wall. A video cassette case characterized in that gates are provided in each of a tape usage amount display window and a tape remaining amount display window.
