Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Use The present invention relates to information cards, and is suitable for application to information cards combined with other card products and/or waterproof information cards.

B Summary of the Invention The first invention can further improve the usefulness of an information card by sharing the power battery with other card products.

Further, the second invention is that in the information card, the wiring board is laminated with a waterproof film.
A dustproof and waterproof information card can be realized.

C. Prior Art As an information card reading device for reading information on a conventional information card, for example, a 2.45 (GHz)
A response request signal Wl using a microwave as a carrier wave is generated in the response request signal generation circuit 2 of the information reading device 1, and is emitted from the transmitting antenna 3 to the information card 4, and the response information signal is returned from the information card 4. By taking W2 into the response signal processing circuit 6 via the receiving antenna 5 of the information reading device 1, it is possible to detect the information card 4, for example, by a person entering or exiting the gate who carries the information card 4 as a person's exit card, or by cargo attached with the information card 4 as a tag. It is being considered to build an information card reading system that can check the information card.

The information card 4 applicable to such an information card reading system includes a dipole antenna 4B attached to a wiring board 4A to form part of a wiring pattern, and an integrated circuit (IC) forming an information signal generation circuit. A wiring pattern 4 connects the information signal generation circuit 4C and the power supply battery 4D of the configuration.
By changing the impedance at the feeding point of the dipole antenna 4B in accordance with the information signal generated by the information signal generation circuit 4C, the reflectance for the carrier wave emitted from the information reading device 1 as the response request signal W1 can be increased. A method has been proposed in which the reflected wave is returned as a response information signal W2 by changing the response information signal W2 (Japanese Patent Application No. 63-6292).

The information signal generation circuit 4C has an electrical circuit configuration as shown in FIG. The address signal S3 of the address counter 13 that performs a counting operation is read out and supplied to the variable impedance circuit 14, which is made of, for example, a field effect transistor.

The variable impedance circuit 14 has a pair of feed point terminals T1
and T2, and when the information data S1 becomes logic "1" or logic "0", the field effect transistor turns on or off, and the feed point terminal T
The impedance at the feeding point of the dipole antenna 4B connected to T1 and T2 is variably controlled, and thus the reflectance for the response request signal W1 incident on the dipole antenna 4B is variably controlled.

A tiflXit battery 4D is connected between the ground side feed point terminal T1 and the power supply terminal T3 of the information signal generation circuit 4C,
As a result, the dipole antenna 4 according to the information data S1
The variable impedance control at the feeding point B can be performed continuously at all times.

A unique identification code is assigned to each information card 4 in the information memory 11, so that the information reading device 1 can reliably read the information held by the information card 4.

D Problems to be Solved by the Invention By the way, conventional card products are not limited to the above-mentioned information card 4, but include card radios, card calculators, and many other products. If the card products can be stored in one card, it is thought that an information card 4 that is much more useful can be realized.

Further, in such a case, since the information card 4 is not limited to use in a situation where the information reading device 1 is installed, it is required to have higher dustproof and waterproof properties than the information card.

Conventionally, such an information card has been proposed that combines a card calculator with the function of an identification card (Japanese Unexamined Patent Publication No. 147388/1988).

However, in an information card with such a configuration, a new signal is generated and output from the external connection terminal in response to input from the external connection terminal, which makes the operation complicated and complicated. However, there were problems with dustproofness and waterproofness, and ultimately the usability was still insufficient.

The present invention has been made in consideration of the above points, and aims to solve the conventional problems at once and propose a highly useful information card.

E Means for Solving the Problem In order to solve the problem, in the first invention, the information card circuits 4B, 4C14E and the card product circuit 22 are provided.
．． In the information card 20 having 23, the power supply battery 21 is shared by the information card circuits 4B, 4C, 4E and the card product circuits 22 and 23.

Further, in the second invention, the wiring board 4A is laminated with a waterproof film 24.

By sharing the power supply battery 21 of the F action information card circuits 4B and 4C14E with other card product circuits 22 and 23, usability can be further improved, and the wiring board 4A can be laminated with a waterproof film 24. By doing so, dustproofness and waterproofness can be improved.

G example An embodiment of the present invention will be described in detail below with reference to the drawings.

A dipole antenna 4B on the upper surface side of the wiring board 4A, an information signal generation circuit 4C, and a paper battery 21 are connected by a wiring pattern 4E.

Further, in the case of this information card 20, a circuit component 23 and a paper battery 21 constituting another card product such as a card radio are connected by a wiring pattern 22 to the lower surface side of the wiring board 4A.

Furthermore, in the case of this information card 20, the entire wiring board 4A is covered with, for example, a waterproof plastic film 24 having a predetermined rectangular shape, folded in half, and the opening side 24A formed by three sides of the plastic film 24 is heat welded. By doing so, the entire wiring board 4A is covered with plastic film 2.
The information card 20 is laminated with 4 sheets, thereby making it possible to obtain an information card 20 with high dustproof and waterproof properties.

In the above configuration, for example, at the point of sale of the information card 20 with a card radio, personal identification information etc. are transferred to the information card 20.
By inputting the information into the information memory 11 of the information card 20, even if the information card 20 is lost, if a third party finds it and uses the information reading device 1 described above, the owner of the information card 20 can be immediately known. This can improve the usefulness of the information card 20.

In addition, in this information card 20, the entire wiring board 4A is laminated with a plastic film 24 to have high dustproof and waterproof properties. Moreover, the information card 20 can be used with confidence even when used as a card radio outdoors or at a pool.

According to the above configuration, by sharing the paper battery as the power source battery with the card radio, it is possible to realize an information card with a thin and simple configuration that is extremely useful.

Furthermore, by laminating the entire wiring board with a plastic film, a dustproof and waterproof information card can be realized.

In the above embodiment, the wiring pattern 4E as an information card and the wiring pattern 22 as a card radio are provided on the upper and lower sides of the wiring board, and the entirety is laminated with a plastic film. Alternatively, each wiring pattern may be arranged on a plastic film folded in two.

That is, in the second figure, parts corresponding to those in Figure 1 are given the same reference numerals.
As shown in the figure, in the information card 30, the dipole antenna 4B, the information signal generation circuit 4C, and the positive side electrode 21A of the paper battery 21 are arranged in a wiring pattern 4E inside the upper part 31A of the plastic film 31 folded in half. It is connected.

Furthermore, the circuit components 23 and the negative electrode 21B of the paper battery 21 are connected to the inner side of the lower portion 31B of the plastic film 31 folded in two by a wiring pattern 22.

As a result, the separator 2IC is sandwiched between the positive electrode 21A and the negative electrode 21B of the paper battery 21, and
By sandwiching the portions corresponding to the wiring pattern 4E and the wiring pattern 22 between the insulating sheets 32 and thermally welding the opening sides, it is possible to obtain a highly useful information card 30 with a much simpler structure.

Furthermore, in the above embodiments, a case was described in which a plastic film was used as the waterproof film, but the same effect as in the above embodiments can be obtained by using a waterproof film made of vinyl, etc. instead. realizable.

Furthermore, in the above embodiment, a case was described in which a card radio was added to an information card as a card product.
The card product is not limited to this, and a wide variety of card products such as card calculators can be used.

Furthermore, in the above-described embodiment, a case was described in which an identification card for entrance/exit is used as an information card, but the present invention is not limited to this, and for example, cards such as cargo tags, IC cards, train commuter passes, etc. It is suitable for use in various shapes and shapes other than card shapes.
