A microcomputer that detects deck drive or discriminates the presence or absence of deck signal processing according to a signal, a continuous playback key input signal, and a B deck key input signal, and generates a control signal according to the deck signal. And a first switch and a second switch for cutting off or supplying a power supply voltage to the power supply unit applied to the B deck, a third switch for switching the output signals of the A deck and the B deck, and the A deck switched by the third switch. Or a signal processing unit for outputting the B deck output signal as an audio signal, and a signal applied to the microcomputer by determining whether the signal processing unit is present or not. Non determined by having parts of the deck, only the currently driven selectively deck has no power being driven there will be a power consumption by shutting off the power supply to achieve a minimized.
