Abstract: A radiographic imaging apparatus includes an electronic cassette and a console device for radio communication with the electronic cassette. The electronic cassette includes a transmitter for transmitting a beacon for the radio communication. A regulation unit regulates beaconing of the beacon in a predetermined specific state among plural operational states. The console device includes a receiver for receiving the beacon. A communication failure detector checks whether a communication failure has occurred in the radio communication according to a receiving state of the beacon in the receiver. A display panel or speaker generates alert notification to notify the communication failure assuming that the communication failure detector judges that the communication failure has occurred. An operational state detector checks whether the electronic cassette is in the specific state.
