发明名称 SELF DESTRUCT VIDEO TAPE CASSETTE
摘要 A video tape cassette including a supply reel and a take-up reel and guide rollers for guiding the tape from said supply reel to the take-up reel. A portion of the tape is accessible to the reading head of a video player. A mutilating device, such as a cutting blade, is positioned adjacent the path of the leading portion of the tape so that the tape will be cut into strips prior to rewinding the tape on the take-up reel, whereby the video cassette is suitable for a one time only viewing. A cap is provided for locking the supply reel to the housing of the video tape cassette during shipment to prevent rotation of the supply reel. A simple dust cover is provided which may be completely removed from the video tape cassette and which seals the video tape cassette during shipment.
