Abstract
The present invention enables device downsizing by utilizing a light-emitting diode as a plurality of interfaces. A light-emitting diodeof a data communication unit using a light-emitting diode for data communication outputs light when a current flows therethrough. A transmission circuitapplies a forward bias to the light-emitting diodebased on transmission data. A separation circuitoutputs a voltage that changes according to a voltage which is generated in the light-emitting diodewhen the transmission circuitdoes not apply the forward bias to the light-emitting diode
