PROBLEM TO BE SOLVED: To realize positive time setting with simple constitution in an AM-FM receiver. SOLUTION: An AM-FM receiver is provided with an FM receiving circuit 10, an AM receiving circuit 30, a detecting circuit 48 for detecting a time signal, a clock circuit 60 for clocking present time, and a display element 83 for displaying the time. According to the time clocked by the clock circuit 60, an audio signal from the FM receiving circuit 10 is supplied to the detecting circuit 48 at the first predetermined time in a day. According to the time clocked by the clock circuit 60, an audio signal from the AM receiving circuit 30 is supplied to the detecting circuit 48 at the second predetermined time in a day. The time of the clock circuit 60 is set to the correct time by a detection signal S48 of the detecting circuit 48. |
