<P>PROBLEM TO BE SOLVED: To surely and easily confirm a reading operation by each antenna when a plurality of antennas are installed in a reader/writer device. <P>SOLUTION: A plurality of loop antennas 14a to 14n are connected through an antenna switcher 13 to a reader/writer device 12. The loop antennas 14a to 14n are configured as antennas for communicating with an IC tag 16 for article management mounted on an article, and installed in a positional relation which does not affect each other. Also, IC tags 15a to 15n for identification are mounted on the loop antennas 14a to 14n. The reader/writer device 12 successively selects the loop antennas 14a to 14n by switching an antenna switcher 13 according to the control instruction of a controller 11, and reads the response data of the IC tag 16 for article management in a communication region and the response data of the IC 15a to 15n for identification, and demodulates and outputs the response data to a controller 11. <P>COPYRIGHT: (C)2007,JPO&INPIT |
