音防止回路。In a cassette tape recorder that is configured to slide a sliding board on which a magnetic head is mounted to an operating position by the rotational force of an electric motor and has an absentee recording function, a power switch closing or timer device is used. a motor that starts rotating when power is supplied to the motor and displaces the sliding board to an operating position during playback or recording operations; and a delay circuit that operates only when the power is turned on and delays the start of rotation of the motor for a predetermined period of time. The recording of the noise caused by the start-up of the recording amplifier circuit on the magnetic tape is prevented by the delay time caused by the delay circuit and the time required for the sliding board to be displaced to the operating position by the rotational force of the electric motor. A noise prevention circuit for a cassette tape recorder featuring:
