[0002]
[Prior art]
Conventionally, “non-contact IC tag” having an integrated circuit with memory in an article (generally, “non-contact data carrier”, “wireless IC tag”, “non-contact IC”, “non-contact IC label”, “RF- In some cases, it is expressed as “ID tag” or the like, and various types of information are recorded to manage goods, rationalize logistics, or display product information.
There are various embodiments of this “non-contact IC tag”. In addition to directly attaching the non-contact IC tag to a document or article, the non-contact IC tag label is attached to the article. It has been broken.
[0003]
As an example of the non-contact IC tag, an antenna pattern is printed and an IC chip is attached to the antenna pattern terminal or coiled so that information can be transmitted and received with an external device by radio waves. The antenna terminal and the IC chip are connected to each other.
And when the base material of the non-contact IC tag is a thin layer material such as paper, when providing the antenna pattern, using conductive ink, printing such as offset, gravure, flexo, silk screen printing, etc. Is provided.

[0009]
As shown in FIG. 1, the paper 1 in which the antenna unit of the embodiment of the present invention is inserted is in a state where the conductive material 3 has a function as an antenna between the paper layers of one pulp base paper 2. It has a built-in structure in a state where it is inserted.
For example, in the stage of manufacturing two or more layers of paper, the conductive material 3 is inserted between the paper layers in a state having the function as an antenna, so that the paper with the antenna already built in the paper can be obtained. It is manufactured.
[0010]
A method for producing a sheet in which the antenna unit of the present invention is inserted will be described with reference to a circular paper machine 4 having two cylinders shown in FIG.
The circular net paper machine 4 is an apparatus for producing a two-layered laminated paper having two cylinders. The two wire cylinders 5a and 5b are respectively connected to the paper material 7a and the paper material 7a in the cylinder pads 6a and 6b. The paper layer is rotated while being immersed in 7b, and a paper layer is formed on the wire mesh of the cylinder using the difference in water level between the inside and outside of the wire cylinders 5a and 5b.
[0011]
And the ejection apparatus 10 which ejects the electroconductive substance 3 from the nozzle 9 is provided in the space between 2 cylinders, and the electroconductive substance 3 is ejected on the paper layer surface transferred to the blanket 8 by the wire cylinder 5b. Then, the antenna pattern is formed, and further, the paper material 7a in the cylinder pad 6a is laminated on the antenna pattern by the wire cylinder 5a, so that the antenna layer is provided with a function as an antenna between the paper layers of the pulp base paper. .
When the conductive material 3 is ejected from the nozzle 9 of the ejection device 10, it is preferable to use, for example, conductive ink in which carbon, graphite, silver powder, aluminum powder, or a mixture thereof is dispersed in a vehicle.
[0012]
The manufacturing method for pouring the conductive material 3 into the pulp base paper is not limited to the above-described method, and may be swallowed by other production methods.
Further, as the conductive material 3, for example, a metal conductive material such as gold, silver, copper, nickel, and aluminum can be used.
[0013]
In FIG. 3, as an embodiment of the paper in which the antenna portion of the present invention is encased, the conductive paper is electrically connected in parallel to the longitudinal direction of the pulp base paper 2 in a continuous pulp base paper 2 having a predetermined width. A sheet having a striped region L _{1 in} which an antenna pattern made of the conductive material 3 is encased and a striped region L _{2 in} which the conductive material 3 is not encased is shown.
[0014]
The width of the stripe-shaped region L ₁ in which the antenna pattern made of the conductive material 3 is engraved is not particularly limited. When the antenna pattern is formed by the conductive material 3, it functions as an antenna. What is necessary is just to set arbitrarily as a width | variety which becomes a state which has.
A region L ₂ having a stripe shape in which the conductive material 3 is not engraved is used as a region for attaching the IC chip. When the IC chip is attached, the terminal portion of the IC chip sandwiches the IC chip. What is necessary is just to set so that it can couple | bond with the antenna pattern by the electroconductive substance 3 of both sides formed by (5) electrostatically.
[0015]
And when producing a non-contact IC tag using the paper in which the antenna part of the present invention is inserted, the continuous pulp base paper 2 is moved in the longitudinal direction as shown in FIG. First, an arbitrary design is printed on the surface of the paper by a printing process.
Thereafter, after an IC chip attaching step in which the IC chip 11 is attached to the region L _{2 having a} stripe shape in which the conductive material 3 is not engraved with a predetermined interval, a predetermined cutting schedule is made. Cutting is performed by a cutting machine for each non-contact IC tag to which the IC chip 11 is attached by the line 12.
As a result, a non-contact IC tag 13 as shown in FIG. 6 is produced, and can be attached to a book cover or body, a package, a paper container blank, or the like by cutting into a desired size shape by a cutting process. The non-contact IC tag 13 can be manufactured.
[0016]
【Effect of the invention】
As described above, the paper in which the antenna unit of the present invention is inserted is provided in a state where the antenna pattern does not appear on the surface of the paper in the non-contact IC tag using the paper as a base material. There is an effect that the printed design is not obstructed by the antenna pattern.
Further, as compared with the case where the antenna pattern is provided by printing, there is an effect that the production efficiency is good because the manufacturing process is less.
