<P>PROBLEM TO BE SOLVED: To adjust the position of an antenna for detecting the information of an IC tag imparted to a buried object to an optimum position and to write information to the IC tag of the buried object. <P>SOLUTION: Every time a motor is rotated for a predetermined amount and the antenna to the IC tag is rotated by a predetermined angle each, the read success rate of the information of the IC tag acquired by an IC tag reader/writer is acquired and recorded in a management table held in storage means. The management table is referred to, the antenna is positioned at a position corresponding to such an angle that the read success rate is optimum by controlling the rotation of the motor, and management information is written to the IC tag by the IC tag reader/writer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
