<P>PROBLEM TO BE SOLVED: To provide an optical identification information acquisition device which can increase the efficiency of communication inexpensively. <P>SOLUTION: IR tags 10.1 to 10.n are attached to objects, respectively, identify corresponding objects and include infrared LEDs 12 which transmit light with light emitting patterns corresponding to identification information for identifying the corresponding objects and light emitting patterns for expressing attribute information of the corresponding objects, photodiodes 14 which receives control signals and memories 18 for storing the attribute information. An ID tracker 20 receives infrared light from the IR tags 10.1 to 10.n, specifies a position of an identification tag device based on the identification information, acquires the attribute information and transmits the control signals to the IR tags 10.1 to 10.n. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
