PURPOSE:To perform switching to a radio mode while stopping a tape even during tape play and to restart the tape play immediately after a tape changeover switch is operated, by setting a tape/radio power-source changeover switch on the radio side during tuner channel selection and memory channel selection, and switching the switch to the tape side associatively when the tape play is started. CONSTITUTION:When one of memory channels ch1-chn is selected by pressing the corresponding button, one of inverters 51-5n is grounded, so the output side of an OR circuit 6 goes up to a high level and its output is supplied to the reset terminal R of a flip-flop 7, which is reset. Then, the base of a transistor (TR) 10 goes down to a low potential through a resistance R1, so the TR10 turns off to obtain the speaker output of the broadcast corresponding to the selected memory channel. When the tape changeover switch 8 is pressed, its output is inputted to the set terminal S of the flip-flop through an inverter 9 to set the flip- flop 7, so a relay coil 11 is energized to move the power-source changeover switch 4 to the side of a tape power source part 2, allowing tape play. |
