PURPOSE: A proximity sensor is provided to maximize space usability and to be applied to various devices. CONSTITUTION: A proximity sensor (100) comprises a plurality of light sources (130), an optical sensor (160), and a control unit. The optical sensor radiates reflective light. The reflective light corresponds to the whole of light sources or a part of the light sources. The control unit identifies the light sources and a light source corresponding to the reflective light radiated to the optical sensor emitting the light. The control unit determines a proximity degree around the light source. [Reference numerals] (130) 8th light source; (160) Optical sensor; (AA) 1st light source; (BB) 2nd light source; (CC) 3rd light source; (DD) 4th light source; (EE) 5th light source; (FF) 6th light source; (GG) 7th light source |
