PROBLEM TO BE SOLVED: To provide a stock control shelf with an excellent reliability and functionality capable of preventing a generation of electro-magnetic coupling between respective loop antennas disposed at a plurality of shelves. SOLUTION: In the stock control shelf 10, an IC card 5 attached to books 4 and loop antennas 2A of a reader/writer 6 for carrying out a radio communication are assembled to shelves 1a, 1b, 1c for accommodating the books 4. The stock control shelf 10 constitutes a shelf being a casing by a plurality of shelves and the loop antennas 2A are installed on a plurality of shelves 1a, 1b, 1c respectively. Electro-magnetic shielding substances 1a-1, 1b-1 made of metal such as an iron plate, etc., are installed on a lower surface of at least one part, i.e., shelves 1a, 1b of a plurality of shelves 1a, 1b, 1c. |
