  • Magnetic cassette tape record and play apparatus
    Patent number: 4330802
    Abstract: A magnetic cassette tape record and play apparatus wherein the magnetic head thereof is fixed, comprises a push member cooperating with an operation button and which is so disposed as to abut against a pad spring received in a tape cassette. When the tape cassette is loaded or ejected in the stop mode, the push member is pressed against the pad spring to deform it against its urging force, thereby locking the cassette tape in a position untouched by the magnetic head. When the operation button is depressed for the recording or reproduction mode, then the push member is removed from the pad spring, thereby causing the pressure pad to be pressed against the magnetic head with the cassette tape disposed between the pressure pad and the magnetic head.
