摘要： An light source control unit controls the flashing of a light source and the light amount of a light source according to information to be transmitted. Thus, light, which is modulated according to the information to be transmitted, is emitted from the light source. The light emitted from the light source is made to enter an optical fiber to pass therethrough and enter a light-scattering body which scatters and radiates the modulated light incident from the optical fiber. The scattered light serves as illumination light as it is. Furthermore, if the illumination light is decoded by a decoding unit after being received by a photoreceptor unit of a receiving set, then information carried by the illumination light can be received.
