  • Lockout device for tape cassette
    Patent number: 4399481
    Abstract: A means whereby a captive movable member is placed in a tape cassette shell aperture. This captive means can be manipulated by the user to effectively block the access of the record lockout lever or allow it to penetrate the cassette shell. Thus the user of the cassette can prevent the accidental erasure or re-recording of the cassette tape when the movable member is in the retracted position, but can deliberately allow re-recording by positioning the movable member to the extended position.
