Patent ID: 7822409

Claim:
A remote control device for controlling an apparatus comprising: at least one key switch; a transmitting device that transmits, when the key switch is pressed, a control signal corresponding to the key switch; and a determining device that determines whether the control signal is transmitted in a form of a single frame comprised of one frame or in a form of a multi-frame comprised of a plurality of frames, wherein the transmitting device repeatedly transmits, in a case where the control signal is transmitted in the form of a single frame, the control signal, with the control signal added to a code indicating the single frame and a discrimination signal of discriminating the control signal transmitted for a first time and the control signal transmitted for a second and subsequent time, and transmits, in a case where the control signal is transmitted in the form of a multi-frame, the control signal while confirming that the control signal is received by the apparatus, with the control signal added to another code indicating the multi-frame and another discrimination signal of discriminating respective frames out of the plurality of frames, and wherein the transmitting device repeatedly transmits, when transmitting the control signal in the form of the single frame, the control signal, and prevents, when receiving a response signal corresponding to the control signal from the apparatus, transmitting the control signal in the form of the single frame in accordance with the key switch having being pressed.
