The substrate is made of beryum copper, gold, silver, stainless steel, tungsten, molybdenum, etc. A large number of information dots 3 are provided between the substrates 1 and 2.
This magnetic dot 3 is made of powder of soft magnetic material or Fe,
The dots are formed as dots with a diameter of about 1 to 5 mm using magnetic powder such as Ni or Co with a coercive force of 10 oersted or less, such as magnetic ink mainly composed of particles with a particle size of about 0.5 to 5 μm. The magnetic dot 3 is not magnetized, and its existence constitutes information. The surfaces of the boards 1 and 2 are marked with letters, numbers, and visual information.
Symbols, photographs, etc. are printed. The thickness of substrates 1 and 2 is
The thickness is preferably about 0.1 to 0.5 mm, and the overall thickness is preferably about 0.6 to 1.2 mm, but one substrate may be thicker than the other, for example, about 1.0 mm.
When paper is used as a substrate, it is hermetically coated with a plastic film, for example a polyester film, for mechanical reinforcement and moisture protection. The information dots 3 are formed by thinly fixing a magnetic powder component onto one surface of the substrate 1 or 2 by printing, transferring, plating, or other methods. Therefore, there is no need to consider the thickness of the information dots.

したものがある。 The manufacturing method for such a lamicard is described in Japanese Patent Application No. 122876/1987 filed by the same applicant, entitled "Method for Manufacturing a Lamicard".
is exemplified in. In addition, for reading such lami cards, a patent application filed in 1972 by the same applicant is required.
As described in No. 70230, ``Information Processing Methods,'' each channel is read using a magnetoelectric transducer, such as a magnetoresistive element, magnetically biased by a direct current magnetic field. A specific information reading device is the patent application No. 119726 filed by the same applicant.
The structure of the "Multi-channel magnetic sensor" is that each channel is independent, and a number of sensor sections each consisting of a pair of magnetoresistive elements fixed on a permanent magnet are arranged side by side, thereby eliminating crosstalk between adjacent channels. There are some that have significantly improved.

は10進数１〜15となる。 Figure 2 explains an example of the formation of unique information by information dots. When the laminate card advances in the four directions of arrows, the channels are divided in the direction perpendicular to arrow 4, 1CH, 2CH, 3CH, 4CH, 5CH on the drawing. will be established. Center channel segment within channel segments
3CH is provided as a clock channel, with information dots provided in each line segment. Other channel divisions 1CH, 2CH, 4CH, and 5CH correspond to, for example, 2 1 , 2 2 , 2 3 , and 24 bits of the binary code, and the row divisions are decimal numbers 1 to 15.

投入の向が正しいかどうかを判別する。 In the row section 1, information dots 3 are provided in all channel sections 1CH to 5CH. This serves as a signal for inserting the laminate card, and the output of the dot reading sensor section provided for each channel becomes logic "1". By mutually processing these output signals in a comparison circuit or an AND circuit, it is determined whether the direction in which the laminate card is inserted is correct.

る。 Next, in the 2nd row section, information dots are provided at 2CH to 5CH. This signal is used as a signal for determining the front and back sides of the laminated card. Further, line segments 3 to 5 are allocated to display the characters "TEL". If there is no information dot, the number is “0”
Therefore, the information dots are provided at the positions representing the numbers "037327271" in the line segments 6 to 14. The last row segment is where the end of reading signal is obtained. From the above, the meaning of the unique information that this Lami card has is "TEL037327271".
3CHのチヤネル区分はクロツクチヤネルで、
行区分１〜15の位置情報を与え、他のチヤネル区

置を規制する。 The channel classification of 3CH is a clock channel.
It gives position information for line sections 1 to 15 and regulates the reading line section positions for other channel sections 1CH, 2CH, 4CH, and 5CH.

変動しても、他のチヤネル区分に設けられた情報
ドツトを正確に読み取る事が出来る。 When inserting a lami card into a reading device, the lami card passes the position of the reading sensor when it passes by manually, by gravity, or when using a conveyance method with an inconsistent conveyance speed. The speed changes from moment to moment. For example, in a natural fall, the falling speed varies from 2 to 2 depending on the conditions at that time.
It changes by a factor of 200. In such cases, the clock channel provides the information dot position as time information to the reading device, so even if the moving speed of the laminate card changes significantly, it is possible to accurately read the information dots provided in other channel sections. I can do it.
又、クロツクチヤネルは、ラミカードのほぼ中

つて、ラミカードの固有情報の読み取りを正確に
行う事が出来る。 In addition, the clock channel is located almost in the center of the Lami Card, so when the Lami Card is moved manually or by natural fall, even if it shakes a little from front to back and from side to side on the drawing, the center part will shake less than the peripheral parts. Almost no error occurs in reading clock information. Therefore, the unique information of the lami card can be read accurately.

ツトの数が例えば奇数となる行区分に設ける。 In the above embodiment, an example of 5 channels was described, but
It can be increased or decreased as necessary. For example, when expanding, you can increase the number of line segments that represent characters. Also, if the number of channels is divided into an even number, there will be an asymmetric number of channel divisions on the left and right sides of the clock channel, so this can be used to obtain a signal to distinguish the front and back of the laminated card. , or even when the number of channels is an odd number, by making the left and right of the clock channels asymmetrical, it is possible to similarly distinguish between the front and the back. In this case, there is no need for line divisions for distinguishing front and back. Furthermore, in order to increase the reliability of reading the LAMI card, channel divisions can be provided to obtain parity bits. The information dots of this channel section are provided in row sections where the number of information dots in the row section is, for example, an odd number.
