2. Description of the Related Art Banknotes, checks, bills, stamps, stamps, stamps, stock certificates, bonds, gift certificates, coupons, prepaid cards,
Securities or ID cards including cash cards, credit cards, and electronic money cards, identification cards, passports, passports, registration cards, admission tickets, departure / entry certificates, documents including certificates of deposit and savings, etc. Due to the nature of the valuable printed matter, it is necessary to have a function of preventing forgery and falsification. As means for preventing such valuable printed matter from forgery or falsification, known methods include plowing, fine image construction, intaglio printing, and the like. At the same time, when determining the authenticity of these valuable printed materials, processing by a machine is required. Therefore, these valuable printed materials must be provided with elements that enable machine reading. For this reason, a method of mixing a special substance suitable for machine reading into ink and a method of coating or mixing a special substance suitable for machine reading on a base material such as paper have been widely used.

[0003] Further, as disclosed in JP-T-2000-501036 "Safety storage document with safety mark", there is also an example in which a pattern of characters or numbers is expressed by arranging fine perforations. is there. Further, there is an example in which a shaded portion of a portrait is expressed based on binarized data expressing a shade after the grayscale image of the portrait is binarized.

[0004] Japanese Patent Application No. 11-35177, entitled "Authentication / Determination Forming Body with Fine Perforations and Authenticity Discrimination Apparatus" discloses a true / false discrimination forming apparatus in which a number of fine perforations are provided in a background portion and an information portion. The body, the perforation provided in the background part and the perforation provided in the information part,
There is disclosed an authenticity discriminating body characterized in that at least one of the shape, size and arrangement direction of the perforations is formed differently.

However, among such anti-counterfeiting means, the pits can be artificially made with a transparent varnish or the like, so that it is difficult to provide a complete anti-counterfeiting means. . In addition, since a fine image configuration can be almost reproduced by a color copying machine, accurate authenticity determination is no longer possible, and in intaglio printing, sufficient finger sensibility is imparted to improve a forgery prevention function. For this purpose, a large area is required as a printing area, so that many problems arise in design.

A typical example of ink used for mechanical reading of valuable printed matter is magnetic ink used for banknotes. Since it is necessary to set a wide allowable range for an error generated when measuring the magnetism of the magnetic ink being used, there is a limit in using the magnetic ink as a complete authenticity discrimination element. Switzerland
In the example of 200 francs, it is possible to easily forge and forge by imitating the arrangement of perforations and perforating,
A method of converting a shade of a portrait into binary data, calculating a position where a perforation is to be arranged as x and y coordinates according to the binary data, and expressing the portrait using a large number of fine perforations. Requires a device having a complicated configuration, and at the same time, it is not always easy to provide a clear reference for the determination of the authenticity.

By the way, in recent years, there has been a remarkable development of a technique for precisely perforating a base material such as paper, a synthetic resin film or a metal plate. For example, a technique for processing a large number of perforations by irradiating a laser beam is known. In addition to being able to easily form perforations at predetermined positions on a base material such as paper, synthetic resin film or metal plate, burr generated at the time of perforation has a sharpened tip for the purpose of forgery or falsification. It is a great feature that it is far less than the case where the hole is simulated by using a means such as a needle.

An object of the present invention is to provide an authenticity discriminating device which is capable of solving the conventional problems by using the technique for precisely processing perforations and having an excellent function of preventing forgery and alteration. As an issue. That is, the present invention provides a method of visually observing from the front under reflected light in normal times, which is constituted by numbers, letters, symbols, codes, patterns, figures, designs, barcodes, etc. through a number of perforations in a part of a valuable printed matter. An object of the present invention is to form a genuineness discrimination device that records difficult predetermined information, thereby enabling genuineness discrimination of a valuable printed matter and preventing forgery and alteration thereof.

On the other hand, the authenticity discriminating device disclosed in Japanese Patent Application No. 11-35177, entitled "Authenticity discriminating body having fine perforations and authenticity discriminating apparatus" has the following problems in manufacturing. I have. That is, in order to form a predetermined pattern by the perforations provided in the information section, at least one or more of the perforations in shape, size and arrangement direction differ between the perforations provided in the background section and the perforations provided in the information section. In order to change the shape and arrangement direction of the perforations between the perforations provided in the background part and the perforations provided in the information part, in addition to the fact that the number of perforations must be huge as a whole, In this case, the mask incorporated in the laser optical path system needs to be replaced, and much processing time is required. Here, the fact that the number of perforations due to the perforations provided in the background portion and the perforations provided in the information section must be enormous is a factor that reduces the strength of the base material, and therefore, the perforation in the authenticity determination device The number is preferably as small as possible.

Therefore, the present invention is directed to a true / false discrimination method configured by combining a large number of perforations obtained by using a technique for precisely processing perforations by irradiating a laser beam and an image printed using ink. Provided is a device, which is a device that can sufficiently secure the strength of a base material and can reduce processing time during manufacturing. The authenticity discriminating device constituted by combining a large number of perforations and an image printed using ink is disclosed in Japanese Patent Application No. 11-35177, "Authentication discriminating body having fine perforations and authenticity discrimination. No need to provide perforations in the background compared to the authenticity discriminating device disclosed in "Apparatus", and it is not necessary to change the shape, size and arrangement direction of perforations, so the number of perforations in the authenticity discriminating device In addition, it is possible to sufficiently secure the strength of the substrate by reducing the number of masks, and to shorten the processing time by omitting the time for exchanging the mask in the laser optical path system. Further, the present invention provides a valuable printed matter in which such a true / false discriminating device is formed at least in part, but such a valuable printed matter is forged or falsified by partially including the authenticity discriminating device. It becomes extremely difficult. Here, the valuable printed materials are banknotes, checks, bills, stamps, stamps, certificate stamps, stock certificates, bonds, gift certificates, coupons, prepaid cards, cash cards, credit cards, securities including ID cards, or ID cards. , Including identification cards, passports, passports, registration cards, admission tickets, departure / entry cards, and passbooks to prove identity, rights, and qualifications.
