PROBLEM TO BE SOLVED: To provide an integrated receiver that can execute switching of operation modes (operating states) even if a first operating state switching signal and a second operating state switching signal, for instance are firmly fixed and failed.SOLUTION: An integrated receiver 18 is a receiver of a vehicle body side 6 shared by an electronic key system 3 and a tire air pressure monitoring system 7. When a switching edge of a smart reception request signal Srco or a smart frequency switching signal Scsel input from an collation ECU 8 is detected, a trigger signal generation circuit 38 outputs a trigger signal Strg to a reception IC 20. The reception IC 20 executes mode switching operation when switching own operation mode based on a smart reception request signal Srco and a smart frequency switching signal Scsel contingent on the input of the trigger signal Strg. |
