  • Publication number: 20230206747
    Abstract: A main body device includes a first communicator (an RF communicator) for transmitting and receiving a signal in a first communication scheme, a second communicator (an IR communicator) for receiving a signal in a second communication scheme, and a controller that executes a process in accordance with an operation signal transmitted from an operation device and received via the first communicator or the second communicator. The controller, by communicating with a communication device via the first communicator, determines whether the controller can determine the timing of transmitting or receiving a signal to or from the communication device via the first communicator. If the controller determines that the controller cannot determine such a timing, the controller executes a switching process that causes the operation device to transmit an operation signal in the second communication scheme.
