A remote control device of the present invention is equipped with a plurality of direction keys corresponding to a plurality of switches equally divided in a main body portion of the device. Moreover, in a case where the respective direction keys are individually operated, data in response to the operated direction key is transmitted from a light emitting section. In a case where one of the plurality of direction keys is operated simultaneously with one direction key adjacent to the direction key, data corresponding to a direction key disposed between the direction keys is transmitted.
