A communication distance between a device antenna and a tag antenna is kept substantially constant all the time so that a stable communication range can be obtained and secure and stable communication is performed. A cartridge is provided with a rib contact face to be a positioning reference at attachment, and a cartridge holder portion of an apparatus for communicating with a RFID tag has a positioning pin provided in correspondence with the rib contact face so that even if various cartridges with mutually different tag attribute parameters such as the size of a base tape, an arrangement pitch of a RFID circuit element To and the like are replaced and used appropriately, a distance between a tag antenna and a device antenna is kept substantially constant in cooperation with the positioning pin provided on the side of the apparatus for communicating with a RFID tag corresponding to the rib contact face, regardless of the type of the cartridge.
