<P>PROBLEM TO BE SOLVED: To provide a non-contact IC tag system for supplying a power from a reader/writer side, and for performing stable data signal transmission, and for performing spot-like transmission which does not interfere with each other even when there are several data to be written in an IC tag. <P>SOLUTION: In this non-contact IC tag system 10 equipped with a reader/writer 11 and an IC tag 12, the reader/writer 11 side is provided with a data transmission part 14 for transmitting a predetermined emission pattern with visible rays of light L, and the IC tag 12 side is provided with a data reception part 24 for receiving the emission pattern, wherein data are transmitted through the visible rays of light L, and a power is supplied through a carrier wave R to be transmitted from the reader/writer 11 side to the IC tag 12 side. <P>COPYRIGHT: (C)2009,JPO&INPIT |
