DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information management apparatus for articles stored in a card-attached case with a built-in non-contact IC. More specifically, the present invention provides a non-contact IC card capable of performing short-range to long-distance data communication by storing articles in a case attached to the outer peripheral surface thereof, and then performing information management of those articles. The present invention relates to an information management device for articles stored in a card-attached case with a built-in contact IC.

[0002]

2. Description of the Related Art In recent years, cards with built-in ICs have been frequently used.

[0003] As this kind of IC built-in card, there is a contact IC.
There are a built-in card and a non-contact IC built-in card, and the demand for the latter non-contact IC built-in card which can be used in a non-contact manner is expanding. In recent years, in addition to the non-contact property, the non-contact type IC built-in card which performs data communication over a short distance and a long distance has been remarkably growing.

FIG. 6 is an explanatory plan view showing a conventional card with built-in contactless IC for data communication.

In FIG. 6, reference numeral 1 denotes a conventional card with built-in non-contact IC for data communication, 2 denotes an IC board, and 3 denotes an antenna coil.

That is, the conventional card 1 with a built-in non-contact IC for data communication has a built-in electric circuit composed of an IC base 2 and an antenna coil 3.
An electric circuit composed of the base 2 and the antenna coil 3 is covered with an exterior covering resin material (not shown).

Recently, such a conventional card 1 with built-in non-contact IC for data communication has been used for production management in factories and inventory management in warehouses.

FIG. 7 is an explanatory perspective view showing a state where articles are stored in such a case.

In FIG. 7, reference numeral 1 denotes a conventional card with built-in non-contact IC for data communication and use, 4 denotes a case, and 5 denotes an article.

[0010] That is, as shown in FIG. 7, a product 5 is stored in a case 4, and a conventional card 1 with a built-in non-contact type IC for data communication is attached to the outer front surface of the product storage case 4. ing.

The information data management of the article 5 in the case 4 is as follows.
Information data is communicated in a non-contact manner using an antenna coil 3 built in a conventional card 1 with a built-in data communication and non-contact type IC, and the IC board 2 also performs calculations and recordings.

Here, the data communication distance of the conventional data communication / non-contact type IC built-in card 1 used for production control of products such as factories is several meters to several tens of meters.

Here, the frequency band of the data communication wave used for the non-contact type IC built-in card 1 when performing data communication over a distance range of several meters to several tens of meters is several tens kHz to several hundred kHz.
It is.

On the other hand, the frequency band of the data communication wave used for the IC built-in card 1 used for data communication in the distance range of several cm to several tens cm is used in a high frequency band of several MHz to several GHz. You.

On the other hand, data communication waves are attenuated in the process of propagating in the air, and it is known that the attenuation rate increases exponentially with frequency.

On the other hand, the frequency f at which data communication is possible is approximately determined by Equation 1.

[0017]

(Equation 1)

That is, the frequency f at which data communication is possible depends on the capacitance C of the IC board 2 and the self-inductance L ₀ of the antenna coil 3 as can be seen from Equation 1.

In Equation 1, the capacitance C of the IC board 2 is considered to be constant.

Therefore, when f is reduced in Equation 1, the self-inductance L ₀ is increased, and when f is increased, the self-inductance L ₀ is reduced.

That is, in order to perform data communication at a low frequency where f is small, the self inductance L ₀ of the antenna coil 3 must be increased.

[0022]

[SUMMARY OF THE INVENTION However a non-contact IC built-in card 1 to increase the self-inductance L ₀ of the antenna coil 3 to the internal order to perform data communication at low frequencies, the antenna coil It must be large and have many turns. Naturally, the antenna coil 3 having a large antenna coil and a large number of turns has an increased volume.

In other words, in order for the conventional card 1 with built-in data communication and non-contact type IC to perform data communication at a low frequency in a long distance range of several meters to several tens of meters, the following difficulties occur. Occurs.

(1) The first difficulty is that the volume occupied by the antenna coil 3 becomes large, resulting in a large shape and a large thickness.

(2) The second difficulty is that since the IC board 2 and the antenna coil 3 are built in the conventional card 1 with built-in data communication and non-contact type IC, data communication is performed at a low frequency. Each time it is performed, or when performing data communication at a high frequency,
It is practically difficult to replace the C base 2 with the antenna coil 3. As a result, the conventional data communication and non-contact type I
The C built-in card 1 could only perform data communication at the frequency determined by the equation (1).

For this reason, the conventional card 1 with built-in data communication and non-contact type IC can perform only short-distance data communication or long-distance data communication. In other words, the card 1 with built-in data communication and non-contact type IC manufactured to perform short-distance data communication cannot perform long-distance data communication. The data communication / non-contact type IC built-in card 1 manufactured so as to be able to perform data communication over a short distance could not be performed.

The present invention has been made in view of such a point, and an object of the present invention is to solve the above-mentioned disadvantages of the prior art and to provide a large number of articles existing over a short distance to a long distance. By providing an information management device for a storage case with a non-contact IC built-in card attached case that can perform data communication via a data communication and non-contact type IC built-in card attached to each of the storage cases. is there.

[0028]

SUMMARY OF THE INVENTION The gist of the present invention is to provide a case in which articles can be stored and a card storage portion is provided on one side of the case, and a data storage device attached to the card storage portion and contactlessly. An information management device for a non-contact IC built-in card-attached case storage article, comprising: a non-contact IC built-in card having a built-in antenna coil for transmitting and receiving data and an IC board for storing data. An information management device for articles stored in a card-attached card-attached case, wherein an auxiliary function coil of an antenna coil of the non-contact IC built-in card is built in.

That is, the present invention comprises a card with an IC capable of short-distance data communication at a high frequency, and a case having a built-in auxiliary function coil and having a card storage portion.

As a result, the overall self-inductance can be arbitrarily controlled to an optimum frequency value at which long-distance data communication is possible. As a result, the article data communication can be performed over short distances and over long distances. It can be performed.
