Abstract
In an IC tag issuing apparatus including a plurality of row antenna units arranged by facing the IC tags in multiple rows aligned as an IC tag continuous body in each row, respectively, and conducting communication in an electromagnetic induction method with each of the IC tags of the IC tag continuous body by using a plurality of the row antenna units, a plurality of the row antenna units are arranged in a row direction or in a direction along a conveyance direction of the IC tag continuous body, and each of the row antenna units is electromagnetically shielded except the position faced with the IC tags of the IC tag continuous body (by a shield plate and an antenna case).
Claims20
An IC tag issuing apparatus comprising a plurality of row antenna units arranged by facing IC tags in multiple rows aligned as an IC tag continuous body in each row and configured to communicate via electromagnetic induction with each of the IC tags in the IC tag continuous body via a plurality of the row antenna units, respectively, wherein
- the plurality of the row antenna units are arranged in a row direction or in a direction along a conveyance direction of the IC tag continuous body;
- and
- each of the row antenna units is electromagnetically shielded except at a position facing the IC tags of the IC tag continuous body.
A shield plate including a plurality of row antenna units configured to face IC tags in multiple rows aligned as an IC tag continuous body in each row, respectively, and configured to communicate via electromagnetic induction with each of the IC tags, wherein
- a plurality of the row antenna units are arranged in a zigzag manner in a row direction or in a direction along a conveyance direction of the IC tag continuous body;
- and wherein
- positions except a position facing the IC tags of the IC tag continuous body are electromagnetically shielded.
An IC tag issuing apparatus comprising:
- a plurality of antenna units configured to communicate via electromagnetic induction with each of IC tags arranged in a direction orthogonal to a conveyance direction;
- and
- a shield plate arranged close to and facing the IC tags, wherein
- opening portions are formed in the shield plate,
- each of the plurality of antenna units have a printed board and an antenna element arranged in the printed board,
- each of the plurality of antenna units are arranged such that the printed board fits into an opening portion of the shield plate and each of the plurality of the antenna units is fixed to the shield plate, and
- each of the plurality of antenna units is electromagnetically shielded by the shield plate.
