を特徴とする−系統ダイバーシテイ受信機。 In a single-system diversity receiver including a tape player section and a radio receiver section that can be energized at the same time, the base is connected to the main-sub antenna switching circuit, and the collector is connected to the FM receiver power supply circuit through a resistor and a diode, respectively. two first transistors connected to the power supply circuit for the tape player and having their emitters grounded; a light emitting diode connected between the respective collectors of the first transistors and ground; When connected to the reverse selector switch and the tape player power supply circuit is switched on,
Two second transistors are connected to turn on one of the first transistors and turn off the other, and their bases are connected to the FM receiver power supply circuit, and their collectors are connected to the two second transistors, respectively. two third transistors connected to the outputs of the transistors and having their emitters grounded;
A third transistor is configured such that when the FM receiver power supply circuit is switched on, the on-off state of the first transistor does not depend on the state of the forward-reverse changeover switch. - System diversity receiver.
