DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A paper IC card having a non-contact communication function of the present invention will be described with reference to the drawings. Figure 1
Shows a first embodiment of a paper IC card having a non-contact communication function, and FIG. 2 shows a second embodiment. Both
(A) is a perspective view from the 11 side of the IC tag label,
(B) has shown sectional drawing in the AA line of (A). FIG. 3 shows a cross section of an embodiment in which the central portion of the concave hole is deepened in FIGS. 1 and 2. The scale in the thickness direction in each cross-sectional view is shown enlarged. In the first embodiment of FIG. 1, the antenna pattern 12 is printed on the side of the IC tag label 11 of the paper IC card 1. The antenna pattern is two right-angled triangular patterns 121 and 122.
However, the shape is not limited to a triangular shape and may be any shape as long as it functions as an antenna. The concave hole 3 is provided at a position where both antenna patterns come into contact with each other, and the IC
The tag label 11 is attached.

In the second embodiment of FIG. 2, antenna patterns 121 and 122 are printed on the surface of the paper IC card 1 opposite to the IC tag label 11 side. And
At a position where both antenna patterns are close to each other, a concave hole 3 is provided on the surface of the paper base 1b opposite to the antenna patterns 121 and 122, and the IC tag label 11 is attached.
In the second embodiment, when the IC card is placed on the reader / writer, there is an advantage that the distance between the antennas becomes short and communication becomes easy. In this case, the IC chip 111 and the antenna patterns 121 and 122 are not electrically connected directly to each other, but can function as an antenna by being electrostatically coupled as described later.

As shown in FIG. 3, the concave hole 3 provided in the paper base material 1b.
Is the first to which the IC chip 111 of the IC tag label is inserted.
The concave portion 31 and the second concave portion 32 having a depth corresponding to the thickness of the IC tag label base material 11b can be formed to have two levels of depth. IC chip 111 itself is 0.2-
Since there is a thickness of about 0.5 mm, when the recessed hole 3 is formed in two depths in this way, the IC chip 111
Since the shape does not appear on the label surface, it is preferable in appearance. As shown in FIG. 3, the IC tag label 11 is also provided with small antennas 112 and 113, and bumps (not shown) of the IC chip 111 are connected to the antennas. Antenna 1 of IC tag label 11
Between 12, 113 and the antenna patterns 121, 122,
It is adhered by an anisotropic conductive adhesive (marked with x) or the like so that it conducts only in the vertical direction with respect to the label.
Therefore, in the case of the first embodiment, the IC chip 111 and the antenna patterns 121 and 122 are electrically connected.

The recess 3 can be formed by embossing, counterboring, laser light perforation, or a combination thereof. In the case of embossing, the antenna pattern is pressed but is not cut off, so it is preferable when forming the recessed hole of the first embodiment.
Even in the case of a two-step depth, there is an advantage that the processing speed can be fast because the processing can be performed with one pressing by the embossing die. On the other hand, in the case of using the counterbore processing or the perforation by the laser beam in the first embodiment, the antenna pattern is scraped or burned off. Therefore, it is preferable to use it in the second embodiment in which the antenna surface is not cut. Become.

Although not shown in FIGS. 1 and 2, between the paper base material 1b for a card and the antenna pattern 12 and one or both surfaces of the paper base material on the side without the antenna pattern, Decorative printing on a paper IC card can be provided. Since the antenna pattern 12 is printed with a transparent conductive ink, the pattern is not damaged. However, it is also possible to print the opaque conductive ink first, form the concealing layer, and then apply the decorative printing thereon. In that case, in the case of the first embodiment, it is necessary to consider a configuration of a pattern that allows the IC tag label and the antenna pattern to be connected. In order to secure the thickness of the conductive ink and reduce the electric resistance of the antenna pattern, it is preferable to use the gravure ink, flexo ink, or silk screen ink as the conductive ink, but it is preferable to have good conductivity. A conductive offset ink may be used as long as it can maintain the above.

The small antenna 11 of the IC tag label 11
Nos. 2 and 113 do not need to be transparent conductive inks because they become the back surface of the label base material when they are attached, and may be conductive inks using carbon or aluminum paste.

The paper IC card according to claims 1 to 5 of the present invention means a state after the IC tag label 11 is attached to the recessed hole 3, and the paper IC card substrate according to claim 6 or 7. The material means a state before the IC tag label is mounted by providing the concave hole 3. In the case of a base material for IC cards, the base material and the IC tag label may be provided in a separated set, and the user may combine the label and attach the label to the base material for the IC card before use. it can.

As described in JP-A-7-57545 and JP-A-9-59553, the transparent conductive ink is mainly composed of tin oxide as a conductive powder, and contains antimony, aluminum, boron and the like. Powders doped with metals having different valences, and powders obtained by coating the composition with a nuclear material such as mica powder, potassium titanate, and silica powder can be used. The particle size of the conductive powder needs to be 1 μm or less in terms of transparency, and one having a small refractive index is preferable.
In the case of gravure or silk screen ink, a combination of various resins and solvents can be used, but in the case of flexographic printing, an alcohol-soluble resin is generally used as a rubber letterpress ink.

The paper base material of the card includes coated paper, high-quality paper,
Card paper, resin-coated paper, resin-impregnated paper, synthetic paper, etc. can be used. In order to maintain the insulation between the two pieces of antenna patterns, it is necessary to use paper with low hygroscopicity, and it is also preferable to apply a water resistant coating. When the recessed holes are formed by embossing, it is preferable to use paper having a characteristic that the embossing does not move back (irreversible) as much as possible.

FIG. 4 shows the first embodiment, and FIG. 5 shows the second.
7 shows a transmission / reception circuit between the IC card and the reader / writer in the embodiment of FIG. Correctly, either one of the antenna patterns 121 and 122 in the paper IC card performs the function on the ground side, and the other antenna pattern performs the receiving function. For example, if either one of the antenna patterns touches the human hand, the antenna pattern is on the ground side. In the case of FIG. 4 and FIG. 5, the antenna pattern 122 functions as a ground on the side having a low resistance with respect to the ground. Then,
This means that the antenna pattern 121 receives the radio wave from the reader / writer 2 and also transmits the radio wave from the paper IC card.

4 and 5, in the case of FIG. 4, the antenna pattern 121 and the antenna pattern 112 of the IC tag label and the antenna pattern 122 and the antenna pattern 113 are directly connected, but in FIG. There is a difference in that the electric couplings C1 and C2 are made. AC signals can be received by capacitive coupling. Although the paper base material 1b plays a role of a dielectric between the antenna patterns, it is recognized that there is no remarkable difference in the non-contact communication function between the two under a certain condition. However, the thickness of the paper layer between the antennas is preferably about 0.2 to 0.8 mm.

The reader / writer antenna 21 for reading is
Radio waves having a resonance frequency are transmitted to the non-contact IC tag.
Usually 125-135kHz (medium wave), 13.56MH
A frequency band such as z, 2.45 GHz (microwave) is used. 125-135 kHz and 13.56 MHz are often used for non-contact IC tags and IC cards, but even if they have the same frequency, they cannot be shared because the communication systems differ from one company to another. When reading response waves from a large number of cards, data collision may occur,
It is necessary to avoid it, and various methods for avoiding collisions and reading are known.

When a paper IC card is used for game purposes, a character or the like is printed, and data relating to the function or power (output) of the character is transferred to the IC.
If you record it on a chip, you can enjoy your own game. For example, cards of different characters may be matched to compete for function and / or power, one of the winning cards may be awarded a point, and the power thus changed may be recorded on the IC chip. In this case, the "function" is, for example, shogi, which is a straight line of a "koro" or a "Keima" jumping function of Keima, and may be a flying function or a water walking function. The "power" is one-step jump, two-step jump, or infinitely straight forward or backward. Moreover, when a certain character is gathered, it may be made to exhibit a special function and power. In these games, the reader / writer can be enjoyed as a ring or a stadium in the combination of a paper IC card and the reader / writer.
