<P>PROBLEM TO BE SOLVED: To provide an IC tag package reading gate with high versatility, and with less misreadings of an IC tag by leak electric field, even when a plurality of IC tag package reading gates are installed adjacent. <P>SOLUTION: In the IC tag package reading gate, having gate main bodies, provided as a pair on both sides of a fixed region of a lane for conveying a commercial material to which the IC tag is attached in a fixed direction; and IC tag reading means provided to the respective gate main bodies, electric field attenuation means are arranged in fixed regions along the traveling direction of the lane and in front and rear of the respective gate bodies. In addition, in the IC tag package reading gate. the gates are installed adjacent to the sides of the fixed regions of the plurality of lanes, and the leak electric field by radio waves which are radiated from the IC tag reading means provided to the gates is attenuated by the electric field attenuation means, arranged in the fixed regions in front and rear of the gate main in the IC tag package reading gate and the electric field attenuation means arranged in the fixed ares in front and rear of the gate body at the next gate. <P>COPYRIGHT: (C)2010,JPO&INPIT |
