<p>A multifunction receiver (18) shared by an electronic key system (3) and a tire pressure monitoring system (7). The electronic key system (3) verifies an electronic key (2) with a verification control unit (8) of a vehicle body (6) through wireless communication, and the tire pressure monitoring system (7) monitors tire pressure of a tire by transmitting a tire pressure signal from a sensor arranged on the tire to the vehicle body (6) through wireless communication. The multifunction receiver (18) includes a trigger signal generation unit (38) that generates a trigger signal when a level shift occurs in at least one of a first operation mode switch signal and a second operation mode switch signal from the verification control unit (8). A mode setting unit (43) sets an operation mode based on the first operation mode switch signal and the second operation mode switch signal in response to the trigger signal received from the trigger signal generation unit (38).</p> |
