PROBLEM TO BE SOLVED: To decrease the possibility of mal-communication due to an interference of radio waves for reading information when reading information from the RF-ID media being conveyed at a predetermined pitch in plural columns on a conveyance path.SOLUTION: A structure to read information from IC tags 60 being conveyed at a predetermined pitch in five columns on a conveyance path 50 includes readers/writers 10a to 10e provided on every conveyance column for the IC tags 60 on the conveyance path 50 to read information from the IC tags 60 at a timing when the IC tags 60 are conveyed to a region where the IC tag faces the readers/writer. The readers/writers 10a to 10e are arranged displaced in a conveyance direction of the IC tags 60 with respect to the readers/writers on adjacent conveyance columns. A displacement amount of the readers/writers is not an integral multiple of the conveyance pitch of the IC tags 60. |
