Claim Text:
1. A communication device mounted in a working vehicle and configured to execute at least one of reading identification information stored in an identification component attached to a component of the working vehicle and writing the identification information to the identification component, the communication device comprising: a control board comprising: a communication controller that is configured to control an execution of the at least one of reading and writing the identification information; a wireless control circuit that is configured to generate an output of radio waves in response to a command from the communication controller; and a wireless power supply that is configured to supply power to the wireless control circuit; an antenna that is spaced from the control board and configured to transmit the output of the radio waves obtained from the wireless control circuit based on the wireless control circuit being supplied with power; and a connection cable that is configured to electrically connect the control board to the antenna, wherein the control board comprises: a disconnection detector that is configured to detect a disconnection of the connection cable; a transmission controller that is configured to transmit the output of the radio waves from the wireless control circuit to the antenna based on the wireless control circuit being supplied with power and to interrupt a transmission of the output of the radio waves from the wireless control circuit to the antenna based on the disconnection detector determining that the connection cable is disconnected; and a wireless power supply controller that is configured, based on the disconnection detector determining that the connection cable is disconnected, to interrupt the supply of power to the wireless control circuit in response to a command signal from the transmission controller before the output of the radio waves is transmitted from the wireless control circuit to the antenna.
