摘要：<P>PROBLEM TO BE SOLVED: To provide a radio IC tag reader (capable of high-speed reading) whose reading range is extended, and to provide a moving-body reading system which does not require complicated control, utilizes radio IC tags and the radio IC tag reader, and is highly reliable. <P>SOLUTION: The radio IC tag reader is equipped with a plurality of antennas 26, 27, 28, 29 for reading, by radio, data stored in a radio IC tag attached to a moving body, and has the following function. When a certain antenna among the plurality of antennas 26, 27, 28, 29 becomes incapable of detecting the radio IC tag, while data stored in the radio IC tag are read by the use of the plurality of antennas 26, 27, 28, 29, the reading operation for the data stored in the radio IC tag is interrupted, the antenna is switched over to a certain antenna among the plurality of antennas in a predetermined order, the antenna searches for the radio IC tag having become undetectable, and the interrupted reading operation for the data stored in the radio IC tag is resumed. <P>COPYRIGHT: (C)2007,JPO&INPIT
