<p>PURPOSE:To improve operation of a device, by supplying power to tuner and amplifier of a radio receiver via the operation switch of a tape deck. CONSTITUTION:The power supply fed from a battery 3 to a deck 1 is supplied to regenerative amplifiers 7, 8 and emitter follower circuits 9, 10 via a playback side contact 6a of a switch 6 and to a control circuit 5 of the deck via an operation side contact 4a of a switch 4, and further fed to a terminal 1c to be fed to the amplifier A of a radio receiver 2 for the playback of tape. When the switch 6 is selected to a recording side contact 6b and recording/playback switches 17, 18 to recording side R respectively, the power supply is fed to recording circuits 13, 14 of the deck 1, and recording is made by monitoring the output of a radio fed to the tuner T and amplifier A of the radio receiver 2. When the switch 4 is switched to the stop side 4b, the radio receiver only is operated to make listenable the radio receiver.</p> |
