  Conventionally, it is common to remotely operate an electric product using a remote controller that transmits an operation signal using infrared rays. However, since the infrared emitting device mounted on the remote controller for operating the conventional electrical product lacks the light collecting means, the distance between the remote control and the infrared receiver mounted on the electrical product exceeds about 20 meters. In other words, the infrared operation signal diverges in the middle, and the receiver cannot recognize the infrared operation signal, so that the electric product cannot be operated. As described above, a remote controller equipped with a conventional infrared emitting device has a short effective transfer distance of only about 20 meters, and is not suitable for a wide place such as a live venue or a large conference room.
