Zusammenfassung: | PROBLEM TO BE SOLVED: To read RFID tag information not depending on the antenna position of an RFID tag in conveyance containers such as cargo cars, which are provided with the RFID tag. SOLUTION: In the cargo car 1, a plurality of induction antennas 22-1 to 22-3 are formed on a metal flame 3 that forms its peripheral and connected to an RFID-side induction antenna 24 through a metal coated conductive line 23. In addition, the RFID tag 10 is held at an RFID tag fixture 4 to place the RFID side induction antenna 24 and a transmitting and receiving antenna of the RFID tag 10 so as to be faced with each other.
