める切換制御手段とよりなる車載用受信機。 A reproducing unit that reproduces an audio signal from a recording medium is supplied with a modulated radio broadcast signal, outputs a radio broadcast signal obtained by demodulating the modulated radio broadcast signal, and outputs an output DC voltage corresponding to the received electric field strength. A receiving section for outputting, a playback signal and a radio broadcast signal are supplied from the playback section and the reception section, respectively, a switching circuit for selectively outputting one of the signals, and a switching circuit for selectively outputting the playback signal from the switching circuit. when the output DC voltage corresponding to the received electric field strength from the receiving section becomes larger than a predetermined first switching setting level, the switching circuit selectively outputs the radio broadcast signal; When the radio broadcast signal is selectively output from the switching circuit, when the output DC voltage becomes smaller than the second switching setting level, which is selected to be lower than the first switching setting level. An on-vehicle receiver comprising switching control means for causing the switching circuit to selectively output the reproduced signal.
