Zusammenfassung:PROBLEM TO BE SOLVED: To easily receive an FM broadcasting signal with a television signal reception tuner and further to prevent the influence of another interference signal, when receiving a television signal or the FM broadcasting signal. SOLUTION: Between a 1st input terminal 1 and a VHF input turning circuit 7, a television signal input circuit 19 is provided for passing television signals and between a 2nd input terminal 9 and the VHF input tuning circuit 7, an FM-broadcasting signal input circuit 25 is provided for passing the FM- broadcasting signals. In this case, when receiving this television signal, the FM-broadcasting signal input circuit 25 is disconnected from the television signal input circuit 19 and the VHF input turning circuit 7 in the manner of high frequency. When receiving this FM-broadcasting signal, the television signal input circuit 19 is disconnected from the FM-broadcasting signal input circuit 25 and the VHF input tuning circuit 7 is the manner of high frequency.
