<P>PROBLEM TO BE SOLVED: To provide a frequency identification reading device having a multidimensional antenna array, scanning a large number of wireless identification tag devices to effectively recognize positions of the wireless frequency tag devices. <P>SOLUTION: An antenna or a coil of a frequency identification device is changed by use of an electronic circuit method to form the multidimensional antenna array. Thereby, an identification code of the wireless frequency identification tag device is detected by a scan method of frequency identification technology, and the position of the wireless frequency identification tag device is positively recognized by the scan method. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
