としている。 Recently, magnetic cards for cash dispensers or POS (points/points) have been introduced to save labor in finance.
Magnetic cards, such as those used for cashless purchases, have come into widespread use. However, if the magnetic stripe on the magnetic card is damaged, or the cash dispenser or POS terminal (also called a card reader, card authorizer, card verification machine, etc.) is damaged, the information recorded on the card may be damaged. It became impossible to verify the password, which caused a great deal of practical inconvenience.
For this purpose, a photo of the card holder's face is imbedded inseparably into the card itself using silver halide photography, fixed using electrostatic photography, or formed using a Polaroid or engraving method. It has come to be used to verify identity by checking the photo of the card. Regarding the method of forming facial photographs on cards using the engraving method, for example,
It has been disclosed in Japanese Patent Application Laid-open No. 25078 and Japanese Patent Application Laid-open No. 150113/1983, and is about to be used by some financial institutions.

性の点で難点がある。 The images on these image cards are only visible to the naked eye, but electrical verification devices and central processing computers have generally been used in connection with these magnetic cards, and the information between them is For replacement, it is desirable that the image on the image-attached card is not only visible but also easily readable as an electrical signal. On the other hand, it is quite possible to read out an image obtained by conventional silver halide photography as an electrical signal using current video technology, but with an image that can only be detected optically, If contaminated, the signal-to-noise ratio of the readout signal immediately decreases, which poses a problem in terms of reliability.
本発明の目的は、このような事情にかんがみ
て、目視可能で且つ電気的信号としても信頼性よ
く容易に読み出しうるような画像を記録しうるよ
うな画像付カードを提供することである。 In view of the above circumstances, an object of the present invention is to provide an image-bearing card capable of recording an image that is visible to the eye and that can be read easily and reliably as an electrical signal.
このような本発明の目的は、カード基板の所望

る。 An object of the present invention is to form a thin layer portion with a magnetic recording material at a desired location on a card substrate to form an image forming portion, and to partially form the thin layer portion depending on the image to be recorded. This is achieved by making the image visible and magnetically readable.

こともでき、カードの偽造防止にも役立つ。 If the card with a magnetic image of the present invention is used, for example, the thin layer for image formation can be partially changed according to the face photograph of the card holder, and the face photograph can be recorded. This not only makes it possible to match a photograph of a person's face with the person in question, but it also makes it possible to read the photograph of the face using a magnetic sensor, magnetic head, etc. and easily transmit it as an electrical signal, if necessary. If you can do something like this,
The magnetic image of the face created when the card is issued is sent to the CPU.
(Central processing computer) and compare it with the signal transmitted when the card is used to confirm whether it is the same as the one at the time of issue. It also helps prevent counterfeiting.
また、本発明によるカードにおける磁気的画像

くても良いことは勿論である。 FIG. 1 shows a perspective view of a card with a magnetic image as an embodiment of the present invention, and reference number 1 indicates
A card board is shown, and this card board 1 is as follows:
Generally; polyvinyl chloride board (white) containing TiO 2 (titanium white), known plastic board such as polystyrene polycarbonate, ABS melamine, polyacrylic, or a laminate thereof, synthetic paper, resin-impregnated paper, or non-magnetic Aluminum, copper, alloys thereof, etc. can be used. It is also possible to use the above-mentioned composites. An image forming section 2 is integrally and inseparably formed at a desired position on this substrate 1 using a magnetic recording material. FIG. 2 shows a partially enlarged cross section of the base 1 along the line X-X'.
As shown in FIG. 2, the image forming section 2 is embedded in the card base 1, reference number 21 indicates a magnetic recording medium, and reference number 22 indicates its protective film. This protective film 22 prevents the magnetic recording medium 21 from being damaged due to friction, attraction, etc., and since it is a technique commonly used by those skilled in the art, the details will be omitted. Of course, this protective film 22 may be omitted. The lower layer of the magnetic recording medium layer 21 is a colored layer having a different color tone from the magnetic recording medium layer 21, and generally has a thickness of 10 μm.
The light-colored film described above is formed by a hot stamping method, a screen printing method, a laminating method, or the like. This is also a technique well known to those skilled in the art, so the details will be omitted. Of course, if the color tone of the substrate 1 is different from that of the magnetic recording medium 21 (for example, a white-colored substrate containing TiO 2 powder used in general cards), it is of course unnecessary to take the trouble to form the colored layer 4. It is.

A film with a thickness of about 12 μ using Fe 3 O 4 (black, Hc about 360 Oe, Br about 1100 Gauss) is sufficient. Depending on the purpose
It may be about 3μ. These are hot stamping method,
Alternatively, the magnetic ink (paint) may be formed to have a uniform thickness by screen printing or other printing method. This method is also a method commonly used by those skilled in the art, so details will be omitted. In addition, α-Fe 2 O 3 powder (brown Hc, 200Oe

2. The magnetic recording medium 21 and the colored layer 23 are laminated on the card substrate 1 as shown in FIG.
In FIG. 2, the upper surface of the protective film 22 is made flat with the upper surface of the substrate 1, but only the image forming section 2 is thickened by the thickness of the protective film 22, the magnetic recording medium 21, and the colored layer 23. It doesn't matter if it's on.

も画像読取りは可能である。 To obtain an engraved image such as a facial photograph as shown in FIG. 3, a conventionally known engraving machine such as a variochrishograph may be used. This is obtained by engraving recesses of a size corresponding to the shading of the target image original, and also by making the engraving density of the recesses of a certain size correspond to the shading of the target image original. It is well known that a predetermined engraving image can be obtained by increasing or decreasing the number, so the details will be omitted. FIG. 4 shows a partially enlarged view of the vicinity of the image forming section 2 in FIG. 3. This is shown schematically. The black part is the magnetic recording medium 21, and this is the part that remains without being engraved.
The white part is the part where the magnetic recording medium part 21 has been scraped off, where no magnetic material is present and the colored layer 23 is exposed. A cross section of this Y-Y' portion is shown in FIG.
The black part is the magnetic recording medium 21, and the parts where the magnetic material remains are designated by reference numbers 21A, 21B, and 21.
C, 21D and 21E are respectively shown. Now, in FIG. 5, the magnetic parts 21B, 21
The magnetic material portions 21B, 21C, 21D, 21 are arranged at equal intervals with a width of about 100μ pitch, which is much narrower than the width d of the magnetic medium such as C, 21D, and 21E.
The upper part of E is magnetized by a magnetizing head indicated by the reference symbol Hg in FIG. 4 (when the magnetizing head is used as a ring head, the gap width thereof is W). That is, for example, a plurality of digital signals (pulse signals) are added to the width d of the magnetic film 21B. If this is scanned at a constant speed on the Y-Y' line with a reading head, the number of pulses read on the magnetic films 21B, 21C, 21D, and 21E will be almost the same, and the number of pulses read on the magnetic film 21A will be much larger. It is clear on the drawing. Images are read magnetically based on this principle. This explanation is based on the case where one writing/reading head is used, but this is just a theoretical explanation, and it is not possible to simultaneously write and read with a multi-channel head in the longitudinal direction or width direction of the image. Of course. The pulsed writing of the magnetization can also be carried out by contacting a permanent magnet. Also, just before reading the magnetic image, it is enough to write a magnetization pulse. This is because the presence or absence of magnetic material is fixedly formed by an engraving method, and it is a permanent magnetic fixed record unless there is significant wear. Therefore, it can be said to be an extremely safe recording method, which is very different from conventional writing and reading of signals on magnetic stripes. Of course, image reading is possible even if the image is scanned obliquely.
このように、本方式は画像記録を磁気的にキヤ
ツチしそれを電気信号に変換しうるので画像の伝
送もきわめて有利である。 As described above, this method is extremely advantageous in transmitting images because it can magnetically capture image recording and convert it into electrical signals.

みとることができるものとなる In the above explanation, the magnetic image was created using an engraving method, but it is of course possible to remove unnecessary magnetic material parts using a laser beam or electric discharge machining method. By forming the magnetic material using a magnetic material that can change color and become non-magnetic with heat, the image forming area can be instantaneously heated with a heat distribution according to the image to be recorded, and the magnetic material can be chemically converted. It is also possible to record an image by partially changing the color and making it non-magnetic, and in this case as well, the recorded image will be visible as well as magnetically readable.
