Abstract:
1. A spatial light communication device comprising: a spatial light transmitter which has a light emitting portion for emitting spatial light on which an information signal stored in advance or an information signal input externally is superimposed; and a spatial light receiver which is connected to a handheld terminal, has a light receiving portion for receiving spatial light emitted from the light emitting portion of the spatial light transmitter and also has a light receiving circuit for amplifying and outputting a light receiving signal of the light receiving portion; wherein the spatial light transmitter is provided with the light emitting portion which emits spatial light from a light emitting element, a light emission driving circuit which drives the light emitting element so as to emit light and a transmission signal reproducing portion which modulates a carrier wave by the information signal stored in advance or the information signal input externally to reproduce a transmission signal, thereby outputting the signal to the light emission driving circuit, and the spatial light receiver is provided with a connector portion which is connected to a microphone input terminal of the handheld terminal as a terminal for outputting a light receiving output signal of the light receiving circuit to the handheld terminal.
