<P>PROBLEM TO BE SOLVED: To manage an object to be carried with a radio IC tag attached thereto without complicating the configuration of the entire system. <P>SOLUTION: The radio IC tag system comprises a carrying basket 14 transferred while loading the object 10 to be carried with the radio IC tag 12 attached thereto, and an antenna unit 16 for emitting radio waves for communication with the radio IC tag 12 in a direction crossing the transfer direction of the carrying basket 14. The carrying basket 14 is provided with a radio wave reflector 18 behind the object 10 to be carried when viewed from the traveling direction of the radio waves. The radio wave reflector 18 has irregular surfaces formed in the transfer direction of the carrying basket 14, and moves relative to the antenna unit 16 when transferring the carrying basket 14, thereby changing the reflecting direction of the radio waves in a wide angle. <P>COPYRIGHT: (C)2009,JPO&INPIT |
