[0002]

2. Description of the Related Art In recent years, with the development of an information-oriented society, information is recorded on a card, and information management and payment using the card are performed. In addition, information is recorded on a label attached to a product or the like, and management of the product or the like is performed using this label.

In information management using such a card or label, a non-contact type IC card equipped with an IC capable of writing and reading information in a non-contact state with the card or label, The non-contact type IC label is rapidly spreading due to its excellent convenience.

FIG. 13 is a diagram showing an example of the structure of a conventional non-contact type IC label.

As shown in FIG. 13, the non-contact type IC label according to the conventional example is capable of externally writing and reading information on a base substrate 550 such as a resin sheet.
A C module 510 is mounted and contacts 540
Is connected to the IC module 510 via an electromagnetic wave, and a current is supplied to the IC module 510 by electromagnetic induction from an information writing / reading device (not shown) provided outside, so that writing and reading of information to and from the IC module 510 are disabled. The conductive antenna 520 for contacting is formed in a coil shape.

In the non-contact type IC label 500 constructed as described above, when it approaches an information writing / reading device provided outside, a current is applied to the antenna 520 by electromagnetic induction from the information writing / reading device. This current is supplied to the IC module 510 so that the IC module 510 can be read from the information writing / reading device in the non-contact state.
Information is written to the IC module 510, or the information written to the IC module 510 is read by the information writing / reading device.

FIG. 14 is a diagram for explaining the principle of the information writing / reading operation with respect to the non-contact type IC label 500 shown in FIG.

When information writing / reading is performed with respect to the non-contact type IC label 500 shown in FIG. 13 by an information writing / reading device provided outside, FIG.
4, a current flows through the coiled antenna 600 of the information writing / reading device, which causes the antenna 600 to
The magnetic field H is generated in the direction of emission from the coiled core portion of the.

In this state, when the non-contact type IC label 500 is brought close to the antenna 600 of the information writing / reading device,
The magnetic field H generated by the current flowing through the antenna 600 of the information writing / reading device penetrates the coiled core portion of the antenna 520 of the non-contact type IC label 500, whereby the current flows through the antenna 520.

The current flowing through the antenna 520 contacts the IC module 510 of the non-contact type IC label 500 with a contact 540.
Is supplied via the
Information is written from the information writing / reading device to the IC module 510, or the information written in the IC module 510 is read by the information writing / reading device.

[0011]

In the conventional non-contact type IC label as described above, it is generated in the direction of being emitted from the coiled core portion by the current flowing through the coiled antenna of the information writing / reading device. Magnetic field is non-contact type I
By penetrating the coiled core portion of the C-label antenna, a current flows through the antenna of the non-contact type IC label, and this current is supplied to the IC module of the non-contact type IC label to write or read information. It is to be understood that the antenna of the information writing / reading device and the antenna of the non-contact type IC label face each other, and the antenna of the information writing / reading device and the antenna of the non-contact type IC label are perpendicular to each other. The communication range between the information writing / reading device and the non-contact type IC label is significantly different from the case where the information writing / reading device is arranged.

The magnetic field H generated by the current flowing through 0 is a non-contact type IC
It does not penetrate the coiled core portion of the antenna 520 of the label 500, and the amount of magnetic flux is small.

As a result, when the antenna of the information writing / reading device and the antenna of the non-contact type IC label are arranged to be perpendicular to each other, the antenna of the information writing / reading device and the non-contact type IC label are The communicable distance between the information writing / reading device and the non-contact type IC label becomes extremely short as compared with the case where the antenna is opposed.

Therefore, when writing or reading information to or from a non-contact type IC label,
The antenna of the information writing / reading device and the non-contact type IC label must be opposed to each other, and the relative angle is restricted, and when the non-contact type IC label is attached to an article or the like, the attaching surface is However, there is a problem in that the antenna of the information writing / reading device is limited to a surface that can face the antenna.

The present invention has been made in view of the problems of the above-mentioned conventional technique, and is for information writing / writing.
An RF-ID medium capable of keeping the communicable distance to the information writing / reading device constant regardless of the relative angle to the antenna of the reading device or the sticking surface when sticking to an article. The purpose is to provide.

When writing predetermined information to the medium, the information and the write request are transmitted via the antenna, and the other RF-
When the information written in the ID medium is read, the read request for reading the information is transmitted via the antenna.

(Operation) In the present invention configured as described above, R is applied in a state where the base material is folded along the folding line.
When writing or reading information to or from the F-ID medium, between the antennas of the information writing / reading device and the facing antenna, of the antennas formed in a plurality of regions adjacent to each other via the folding line. Electromagnetic induction occurs and a current flows through the antenna of the RF-ID medium, and this current is supplied to the IC module to write or read information.
