Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an authentication label, a ROM to which the label is attached, and a method of authenticating the ROM.

[0002]

2. Description of the Related Art For example, in a game machine such as a pachinko game machine, a ROM in which a control program is incorporated in advance is used for controlling the way of balls to be ejected in accordance with a game process. The contents of the ROM are unique to each model and machine number of the gaming device, and make a subtle difference between the devices, thereby creating an interesting game.

[0003]

By the way, the case of a pachinko game machine is a typical example, but the above-mentioned ROM is replaced with a forged ROM (so-called back ROM), and a game is played with this machine, and the balls are blown at once. There are many crimes of giving out a lot and cashing out.

Conventionally, a genuine ROM has a seal attached thereto, so that it can be distinguished from a fake ROM. However, this seal can be peeled off relatively easily, and the peeled seal is genuine. A ROM, it cannot be distinguished from a genuine ROM. Also, instead of replacing the sealing paper, it is also possible to copy and seal the sealing paper and attach it to a fake ROM. As described above, there is a problem that it is relatively easy to replace a genuine ROM with a back ROM, and that this kind of crime is rampant, and that this must be prevented by all means.

[0005] The present invention solves the above-mentioned problems and provides a back ROM.
It is an object of the present invention to provide a label for authenticity discrimination in which it is difficult to replace an improper part or the like, an improper device, a ROM to which the label is attached, and a method for judging the authenticity of the ROM.

[0006]

In order to solve the above-mentioned problems, the invention of a label for authenticity discrimination according to claim 1 is provided by forming a brittle layer which is easily broken by an external force and a back side of the brittle layer. And a mark for authenticity identification disposed at an appropriate position on the brittle layer optically readable from the front side of the brittle layer.

The above-mentioned “appropriate position of the brittle layer optically readable from the front side of the brittle layer” means not only the surface on the front side of the brittle layer but also the light beam used by the brittle layer to read the mark. The term “transparent to infrared (including infrared rays, X-rays, and the like)” means the meaning including the inside embedded in the brittle layer.

If the label for authenticity determination of claim 1 is used, the label will be broken if the label is to be peeled off.

According to a second aspect of the present invention, in the first aspect of the present invention, the authenticity identification mark is formed by using an ink having a response characteristic to light having a wavelength other than visible light different from that of a normal ink. It is characterized by being.

The above-mentioned "ink having a response characteristic to light having a wavelength other than visible light which is different from ordinary ink" means, for example, an infrared-absorbing ink having a high absorptivity for light in a specific infrared region, or an infrared-absorbing ink having a high absorption rate. It means an ink that differs from the response characteristics of a commonly used printing ink to light other than visible light, such as an ink that emits fluorescence when receiving light.

When the authentication label according to the second aspect is used, the authentication identification mark cannot be read by a normal copying machine or photographic machine, and the label cannot be copied.

According to a third aspect of the present invention, there is provided the ROM according to the first or second aspect of the invention, wherein the label for authenticity determination is affixed to the surface.

According to a fourth aspect of the present invention, there is provided a ROM authenticity discriminating method, wherein a brittle layer which is easily collapsed by an external force and an appropriate position optically readable from the front side of the brittle layer are provided. An authentication discrimination label having an authentication discrimination mark in which a response characteristic to light having a wavelength other than that of the normal ink is different from that of the normal ink is attached to the ROM, and the authentication discrimination mark is made using the response characteristic. When a genuine mark is detected, a genuine ROM is determined, and when a genuine mark is not detected, a genuine ROM is determined.

According to a third aspect of the present invention, there is provided a method for determining the authenticity of a ROM, comprising using a determination device utilizing a response characteristic to light having a wavelength other than visible light. The authenticity of the ROM can be determined by reading the mark. For example, when infrared absorbing ink is used, there is no reflection of infrared light from the mark portion, so a discriminating device that reads the wavelength range of infrared reflected light is used.When ink that emits fluorescence by infrared irradiation is used, infrared light is used. And a discriminating device for reading the wavelength range of the fluorescent light emitted by the irradiation.

BEST MODE FOR CARRYING OUT THE INVENTION A label for authenticity determination according to the present invention,
An embodiment of a ROM to which this is attached and a method of determining the authenticity of the ROM will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing an embodiment of an authentication discriminating label according to the present invention, FIG. 2 is a plan view showing an example of an authentication discriminating mark of the authentication discriminating label of FIG. Is
The ROM of the present invention to which the label for authenticity determination of FIG.
It is a perspective view which shows the state which has read and inspected the authentication mark.

In FIG. 1, the authenticity determining label 10 is
It is configured as follows. Reference numeral 1 denotes a brittle sheet (brittle layer) made of brittle vinyl chloride. On the back side of the brittle sheet 1, an adhesive layer 2 is formed in close contact, and further on the back side of the adhesive layer 2. A release paper 3 is removably attached to the adhesive surface. The brittle sheet 1 has a remarkably low resistance to tension and shearing force. As described later, the pressure-sensitive adhesive layer 2 is brought into close contact with the surface to which the label is to be adhered, and the authenticity determination label 10 is attached to the ROM surface or the like. If the brittle sheet 1 is to be peeled off after bonding, the brittle sheet 1 becomes ragged and has such a brittle property that it is torn finely.

On the front side of the brittle sheet 1, an authenticity identification mark 4 is printed. The authentication mark 4 is printed using stealth ink (trade name, manufactured by Hitachi Maxell Ltd.) and ordinary ink, as will be described in detail later. The stealth ink contains a special fluorescent agent that emits light when irradiated with infrared rays, and is transparent to the naked eye. Therefore, although clearly shown in the drawing, the portion of the authentication mark 4 printed with stealth ink is not visible.

In the present embodiment, the authentication identification mark 4 is a bar code as shown in FIG. The barcode bars 41, 42,..., 50 are printed with the above stealth ink, and the bars 4a, 4b, 4
c, ‥‥, 4j are printed with normal colored printing ink. The bars 41, 42,... Constitute a genuine code, and the bars 4a, 4b, 4c,. The true bar and the fake bar are
There are some overlapping portions like the bar 42 and the bar 4c. The transparent bars 41, 42,... Are printed on the colored bars 4a, 4b, 4c,.
Only ‥) can be seen, and this is mistaken for an authentication mark. However, the authenticity identification mark is constituted by bars 41, 42,... Which cannot be seen with the naked eye.

The label 10 for authenticity determination is used by peeling the release agent 3 and affixing the adhesive surface of the adhesive layer 2 to the upper surface of the game ROM of the pachinko game machine. The authentication identification mark 4 forms a unique code for each pachinko gaming machine. Therefore, even if the ROM is replaced with a ROM of another machine or replaced with a forged ROM, the replacement is easily found by reading the authenticity discriminating label 10 attached to the ROM.

In order to avoid this forgery discovery, the forgery ROM must be separated from the authentic ROM by a label 1 for authenticity discrimination.
0 or a counterfeit label obtained by copying a genuine authentication mark.

However, the label 10 for authenticity determination is read from the ROM.
If you try to peel off, the brittle sheet 1 crumbles,
The authenticity identification marks 4 also fall apart. Also,
In order to make a copy of the authenticity label 10, a forged label is made by copying the label, taking a picture, or copying the mark for authenticity identification. Pseudo code (4a, 4b, 4
c, ‥‥) and the authenticity identification mark (41, 42, ‥‥) cannot be detected, so that the authenticity identification mark (41, 42, ‥‥) does not exist. Therefore, it is extremely difficult to escape the discovery of forgery by attaching a genuine authentication mark to the forgery ROM and deceiving it.

As shown in FIG. 3, the pachinko game machine side
At the time of startup, the authenticity of the ROM 5 attached to the printed circuit board 7 inside is checked, and the operation is started only when it is determined that the ROM is authentic. If genuine ROM
If it is determined that the operation is not the same, an alarm to that effect is issued and the operation is stopped. That is, RO
The optical inspection device 6 scans the authenticity identification mark 4 of the authenticity identification label 10 affixed to the upper surface of the M5 while irradiating the infrared ray r from the optical inspection device 6, thereby scanning the authenticity identification mark 4 of the authenticity identification mark 4 (41, 42). , ‥‥), the fluorescent light x that is emitted secondarily is received by the optical inspection device 6 to decode the code.

The portions 4a, 4b, 4c,... Printed with colored printing ink in the authenticity identification mark 4 look like a genuine code to the naked eye, but the reflected light therefrom reflects the fluorescent light. Since the wavelength is different from x, nothing is detected by the optical inspection device 6. The colored printing ink marks are intended to deceive the eyes of those attempting to forge the marks. Since the genuine mark is invisible and cannot be copied, the genuine mark in the authenticity identification mark 4 cannot be forged. Note that, of course, the portions 4a, 4b, 4c, and ‥‥ printed with the printing ink may not be provided.

The mark for authenticity identification in the present invention is not limited to the barcode of the above-described embodiment.
Other codes such as a two-dimensional code can be used, and in the case of a game ROM which does not need to identify individual ROMs and only needs to be able to distinguish between a genuine product and a counterfeit product, for example, a fragile product is used. Stealth ink may be applied to the entire surface of the quality layer 1.

As an ink having a response characteristic to light having a wavelength other than visible light different from a normal ink, an infrared absorbing ink containing an infrared absorbing agent in a printing ink can be used in addition to the stealth ink in the above embodiment. . Also, by coloring the stealth ink, the above genuine bar 4
1, 42, ‥‥ and the pseudo bars 4a, 4b, 4c, ‥‥ have the same color, so that the genuine bars 41, 42, ‥‥ cannot be identified by the naked eye or the like, or have the same color and the same pattern as the back. Using stealth ink and infrared absorption ink
The back color and pattern may be camouflaged. The combination and arrangement of these authenticity identification marks (41, 42, ‥‥), which are difficult to identify with the naked eye, and the back or pseudo mark, are clearly identified by the optical inspection device 6. As the optical inspection device 6, a device capable of detecting a genuine authenticity identification mark according to the ink or the like to be used is used.

The optical inspection device 6 may be incorporated in a game machine or the like and used directly for controlling a machine, or the optical inspection device 6 may be incorporated and used in an independent inspection device.

Further, the brittle layer 1 of the authenticity identification mark 4
As described in the above-described embodiment, in addition to arranging the authentication mark 4 on the surface of the brittle layer 1, for example, after printing the mark 4 on the brittle layer, A brittle layer that is optically readable from the front side of the brittle layer, such as overcoating a brittle layer that is easy to see over on the mark 4 and embedding the authentication mark 4 in the brittle layer 1. It may be arranged at an appropriate position.

[0029]

As described above, the present invention has the following functions and effects.

(1) According to the authenticating label according to the first aspect, even if the authenticating label is peeled off and attached to a fake to make it look like a real one, the brittle layer of the label becomes ragged when the label is peeled off. In this case, the authentication mark is broken and the label cannot be peeled off.

(2) According to the authentication discriminating label according to the second aspect, the response characteristic of the authentication discrimination mark to light having a wavelength other than visible light cannot be detected with the naked eye, a copy, or a photograph. The duplication mark cannot be duplicated, making it difficult to make a fake label.

(3) According to the authenticity discriminating method for the ROM according to the third aspect and the ROM according to the fourth aspect, the authenticity identification mark of the attached identity discrimination label is different from that of ordinary printing ink by a visible light. By reading and inspecting using response characteristics to light having wavelengths other than the above, it is possible to easily discriminate between a genuine ROM and a fake ROM (so-called back ROM), thereby preventing the back ROM from being used.
