a pattern reading element disposed on the substrate; a spacer disposed on the substrate so as to surround the pattern reading element; a transparent plate disposed overlappingly on the upper surface of the spacer; and an optical pattern arranged on the lower surface of the transparent plate so as to face each other, and when reading the card, a control unit provided inside and outside the card causes the pattern reading element to read the optical pattern, and the optical pattern is read by the control section provided inside and outside the card. The card is determined to be the correct card when it matches a predetermined pattern, and this makes it impossible to copy this card simply by copying the data on the card to another card. It is something.

(Prior Art) Magnetic cards used in bank automatic teller machines, etc. are composed of a plate-shaped plastic plate as a base and a magnetic stripe provided on a part of this plastic plate. If you insert this magnetic card into an automatic teller machine, etc. and input your PIN number from the numeric keypad, the automatic teller machine, etc. will compare this PIN number with the data pre-stored in the magnetic stripe, and the result of this comparison will be Based on this, it is determined whether this card is the correct one and whether the person who inserted this card is the correct owner.

(Problem to be Solved by the Invention) However, with this type of identification method, a person who has obtained another person's card by some means can read out the data embedded in the magnetic stripe of this card. If you write this on another new card and then return the other person's card to its original owner, two cards will exist without the correct owner knowing.

Furthermore, with cards other than the above-mentioned magnetic cards, such as telephone cards and orange cards, there is a possibility that a person who purchases these cards may make many cards from one card using this method.

In view of the above circumstances, it is an object of the present invention to provide a card that can prevent data from being copied simply by transferring data from one card to another using a card reader, card writer, etc. .

(Means for Solving the Problems) In order to solve the above problems, the card according to the present invention includes a substrate serving as the base of the card, a pattern reading element disposed on this substrate, and a structure surrounding the pattern reading element. a spacer disposed on the substrate; a light-transmitting plate disposed overlappingly on the upper surface of the spacer; and an optical pattern disposed on the lower surface of the light-transmitting plate so as to face the pattern reading element. , when reading the card, a control unit provided inside and outside the card causes the pattern reading element to read the optical pattern, and when the optical pattern matches a predetermined pattern, the card is determined to be a correct card. It is characterized by the fact that it is made to do so.

(optical pattern) 8 and an electrode 9.

The board 2 is a plate made of plastic or the like that serves as the base of the card 1, and a pattern reading element 3 is mounted on the top surface of the board 2.
is provided.

The pattern reading element 3 is composed of a plurality of light receiving elements (photodiodes, phototransistors, etc.) arranged in a matrix (or array, etc.) or a COD (solid state image carrier), etc., and is used for reading this pattern. A spacer 4 is arranged around the element 3.

The spacer 4 is a plastic plate (or a black resin plate) that is thicker than the pattern reading element 3 and has the pattern reading element 3 and the IC circuit 5 cut out, and its lower surface is adhesively fixed to the upper surface of the substrate 2. , and the upper surface is adhesively fixed to the light shielding plate 6.

The light shielding plate 6 is a plate made of an opaque plastic plate, a colored plastic plate, or other thin film material, and a hole is formed in the portion of the light shielding plate 6 facing the pattern reading element 3. A piece of paper 8 is placed in this hole.

The piece of paper 8 has characters or a specific name printed on its underside, or a fingerprint pattern, etc.
Its upper surface is adhesively fixed to the lower surface of the transparent plate 7.

The transparent plate 7 is a plate made of a transparent (or semi-transparent) plastic plate or other material with similar properties, and its lower surface is flat except for the part where the paper strip 8 is attached. It is adhesively fixed to the upper surface of the light shielding plate 6, and a plurality of electrodes 9 are fitted and fixed to a part thereof so as to vertically penetrate through the transparent plate 7 and the light shielding plate 6.

Each electrode 9 is connected to a card 1 on which these electrodes 9 are provided;
The spacer 4 is used to electrically connect external equipment (for example, a card identification device, an automatic teller machine, etc.).
, or the signal I! placed on the light shielding plate 6 portion, etc. (path shown) is connected to the IC circuit 5.

The IC circuit 5 is arranged in the hollowed out part of the spacer 4, and as shown in FIG.
0 and a memory 11.

In this case, the memory 11 includes a setting pattern area 12 in which setting data corresponding to the pattern on the bottom surface of the paper piece 8 is stored in advance as shown in the memory map of FIG.
A reading pattern area 13 in which a pattern read by the pattern reading element 3 is temporarily stored, and a transmission data eraser 14 in which transmission data is stored are provided.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

Now, if this card 1 is inserted into a card identification device or the like, the microprocessor 10 performs step STI in FIG.
Waits until a data request is supplied from the card identification device or the like, and when this request is supplied, data from the pattern reading element 3 is taken in in step ST2.

In this case, the piece of paper 8 facing this pattern reading element 3 is back-illuminated by the light supplied through the transparent plate 7, so that the microprocessor 10 can detect the pattern corresponding to the lower surface of this piece of paper 8. data is supplied,
This data is stored in memory 1 by microprocessor 10.
It is transferred to the reading pattern area 13 of No. 1.

Next, this microprocessor 10 performs step ST3.
The data stored in the reading pattern area 13 and the data stored in the setting pattern area 12 are compared, and if they match, the data in the memory 11 of this card 1 is transferred from another card. It is determined that the card is not a copy, and in step ST4, a code indicating that transmission is possible is supplied to a card identification device or the like.

Thereafter, the microprocessor 10 performs a predetermined process in step ST5, such as supplying the data in the transmission data filter 14 to the card identification device, etc., and then stops this operation.

If the data in the reading pattern area 13 and the data in the setting pattern area 12 do not match in step ST3, the microprocessor 10 branches from step ST3 to step ST6, where the data is sent to the card identification device or the like. It sends a message indicating that transmission is impossible, and then stops operating.

In this embodiment, since the card 1 is provided with the paper piece 8 that cannot be copied, the card 1 cannot be used simply by copying data stored in the memory of another card to this card 1. This can prevent copy cards from being created.

Furthermore, in the embodiment described above, the microprocessor 1
0, the data in the set pattern area 12 and the data in the read pattern area 13 are determined to match, but a card identification device or the like may be used to determine the match.

In addition, the setting pattern area 12 and the transmission data area 14
