Abstract
An ID detection device includes a transmit/receive antenna unit having a transmit/receive antenna and a movement mechanism for making the transmit/receive antenna scan, wherein a file folder in which the RFID tags are arranged close to one another in a row is set on the transmit/receive antenna unit, to make the transmit/receive antenna scan in a row direction in which the RFID tags are arranged.
Claims6
An ID detection device configured to read IDs of individuals of plural RFID tags which are arranged close to one another forming a row of tags, comprising:
- a transmit/receive antenna unit comprising:
- a transmit/receive antenna configured to communicate with the RFID tags;
- a movement mechanism configured to reciprocate the transmit/receive antenna scan in a row direction in which the RFID tags are arranged,
- wherein a file folder binds a plural of sheets to each of which the RFID tag is bonded at a predetermined position to form a tag row constituted by the RFID tags arranged close to one another in a row is placed on the transmit/receive antenna unit so that the movement mechanism reciprocates the transmit/receive antenna linearly in a row direction in which the RFID tags are arranged to communicate with the RFID tags, and
- wherein the transmit/receive antenna has a dipole antenna unit and a reflector part cooperating such that a transmit direction of an electric wave from the transmit/receive antenna and a maximum gain direction of the RFID tags are parallel to one another.
An ID detection method for reading IDS of individuals of plural RFID tags bonded to plural sheets and are arranged close to one another forming a row of tags, comprising:
- organizing the RFID tags on the plural sheets with file folders such that a transmit direction of an electric wave from a transmit/receive antenna and a maximum gain direction of the RFID tags are parallel to one another, so that the RFID tags can be scanned in the row direction by a transmit/receive antenna unit having the transmit/receive antenna and a movement mechanism when the file folders having the tagged sheets are placed in a row on the transmit/receive antenna unit;
- scanning by the movement mechanism the transmit/receive antenna including a dipole antenna and a reflector linearly in a row direction in which the wireless tags are arranged, and
- reciprocating by the movement mechanism the transmit/receive antenna linearly in the row direction in which the RFID tags are arranged.
