Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game store system for monitoring game use of a pachislot machine used as a game for public entertainment, and more particularly to game media such as medals, coins, chips, etc. of the store. The present invention relates to a game store system and a game medium for preventing mixed use and illegal use of game media by distinguishing game media from other stores similar to the above.

[0002]

2. Description of the Related Art In general, game media (hereinafter referred to as medals) used in slot machines used in pachinko parlors, game arcades, and other stores in the game industry are more expensive than pachinko balls. Become a fraudulent target.

[0003] At present, the use status of medals is determined by detecting the insertion of medals by a medal detection sensor inside when a medal is inserted into a medal insertion slot provided in a gaming machine or a reception slot of a medal counter. I have. This type of medal detection sensor determines the presence or absence of a medal based on detection data obtained by reacting when passing a metal medal.

[0004]

However, since such a medal detection sensor has low accuracy in identifying medals, medals are easily used for forgery, and medals from other stores are used in a mixture with medals at the own store. There was something. Therefore, in order to enhance the determination accuracy, the outer diameter, thickness, shape, pattern, presence or absence of perforations, and the like of the medal are recognized by an image, and the medal is also identified by performing some kind of work such as engraving on the medal. However, in this case, an image system is required, which is expensive, and may be illegally used with a similar medal.

Further, as shown in Japanese Patent Application Laid-Open No. 11-53017, a plurality of concentric annular embosses are formed on the front or back surface of a circular medal, and light is applied to the circular emboss to obtain the true medal of the medal. Identify fake and type.

However, when identifying such medals, the usage environment in a game store is extremely poor, such as the adhesion of cigarette tar to the sensor and the generation of metal abrasion powder.
In order to maintain the recognition rate by the detection light, frequent maintenance for the detection sensor is required.

[0007] For these reasons, it is not possible to escape from the viewpoint of counterfeiting simply by making various changes in the outer shape of medals used in gaming stores.

[0008] In addition, Japanese Patent Laid-Open No. 5-57059
As disclosed in Japanese Patent Application Laid-Open No. H8-19409, there is provided a medal manufactured by incorporating a small identification component for emitting an identification signal in the medal itself.

However, in this case, a large impact or external force is frequently applied to the use of the medal, and in this case, the built-in identification component is easily broken or broken, and the medal strength and the durability of the life are reduced. The cost is low, and the manufacturing cost per medal is high. In particular, it cannot be realized in stores that use a large amount of medal, such as one million medals / store, or chain stores that use common medals because of the high cost. Had.

Therefore, the present invention provides a method for preventing forgery of a game medium by manufacturing the game medium using a metal material peculiar to the game medium. An object of the present invention is to provide a game store system and a game medium having a forgery prevention function capable of completely eliminating improper psychology with respect to a fraudulent planner, because a forgery point can not be narrowed down because it can be clearly distinguished and eliminated. .

[0011]

SUMMARY OF THE INVENTION According to the present invention, when monitoring whether or not a game medium used in a game machine or a counter provided in a game store is a medium issued by the own store, the game medium is made of a unique material. By manufacturing and providing a material sensor for identifying a specific material of the game medium in the game machine or / and the counter of the own store, when a game medium having the specific material is used for the game machine, The material sensor detects a specific material and determines that the game medium is valid. On the other hand, when a game medium of any other material is used, it can be determined to be invalid.

As described above, since the material itself of the game medium is detected and identified, high discrimination performance can be obtained. Instead of acquiring surface data from the outer shape of the game medium, the material inside the medium is determined, so that it is possible to accurately distinguish between the game medium of the own store and the game medium of another store.

In the production of this game medium, it is possible to select and produce one specific type from among many types of components of the same kind of metal material having different components and having slightly different components. This makes it difficult to select and imitate one of many similar types even when attempting to forge, which is effective in preventing forgery.

For example, a specific type that can be easily identified by a material sensor from the JIS standard list of stainless steel can be selected and used. In addition, if two or three kinds of stainless steel game media are prepared and set in a system in which the type of game media used is changed every arbitrary date, illegal use by forgery can be completely prevented. .

At this time, the size, color, and size of each medium manufactured separately for a plurality of types using the same kind of metal material having different contained components.
If the appearance identification elements such as the shape and weight are set to be the same, a plurality of types of manufactured game media, for example, two to three types, cannot be distinguished only from the external appearance, and a game media unique to the own store is established. Operation management.

As described above, the manufacturing cost per game medium can be reduced and the cost can be reduced. In addition, the combination of the game medium having a specific material and the material sensor can provide high-precision discrimination performance. If the system can be constructed and each material sensor is provided in a game machine or a counter, a counterfeit game medium and its use status can be easily monitored.

Here, the specific material is, for example, a metal material such as stainless steel, and is not limited to using only a plurality of types of stainless steel according to JIS-standardized components. In addition, various kinds of new metal materials can be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. The drawing shows a game store system. In FIG. 1, this game store system is incorporated into a building 11 in the city, or a first game store 12a, a second game store 12b such as a pachislot store opened independently, and 3
This is for managing medals to be used for each game of the game stores 12c.
2b, 12c... Are managed so that medals for each store are not used together with medals from other stores, and counterfeit medals are not used.

FIG. 2 shows a system configuration in a game store.
The gaming machine has a system configuration in which a plurality of first slot machine units 21a, second slot machine units 21b,... Are arranged and arranged in the store.
And a plurality of first counters 22a, second counters 22b,... Arranged at several places for replacement medals.
Are wired to the control unit 23.

The metal materials of the medals are detected inside the medal receiving openings of the above-described slot machine tables 21a and the counters 22a and used to determine whether or not the medal is a valid medal exclusive for the store. It has a sensor.

FIG. 3 shows a control circuit block diagram of the material sensor S. A CPU 31 having a clock generation source 31a transmits a constant transmission signal generated from a clock, for example, a constant transmission signal of 5 KHz to a first low-pass filter (LPF) 32. Output. The first LPF 32 removes the high-frequency component of this signal and adds it to the excitation amplifier 33 as a sine wave.
Excitation amplifier 33 amplifies this signal to transmit coil 34a.
Is to be driven.

A transmission coil 34a and a reception coil 34b are provided on both sides of the path through which the medal M passes, and the reception coil 34b receives an induced electromotive force that changes as the medal M passes. Through the second LP
F36. The second LPF 36 is a preamplifier 35
By cutting off the high-frequency component of the output, a received signal having the same frequency as the exciting current waveform of the transmitting coil 34a is detected. The output of the second LPF 36 is input to an A / D conversion input terminal of the CPU 31.

A memory 37 for holding the control program is connected to the CPU 31. The CPU 37 identifies the metal material of the medal M passing therethrough according to the A / D conversion output, and
8 for output. The reference voltage source 39 supplies a voltage to each unit.

At the time of detection by the material sensor S, when considering the metal material constituting the medal M, attention is paid to the fact that the magnetic permeability and the dielectric constant are different for each metal material, and the difference between the magnetic permeability and the dielectric constant is determined. It is used to identify the metal material by effective use.

As shown in FIGS. 4 and 5, a basic waveform 40 having a basic phase difference θ40 and a basic height ∫40,
When the first to third measurement waveforms 41, 42, and 43 on the receiving coil side obtained by actually detecting and measuring a medal of a metal material are compared, the first to third measurement waveforms 41 to 41 on the receiving coil side are compared.
43 is a first to third measured phase difference θ4 compared to the basic waveform 40.
1, θ42, θ43 and first to third measurement heights ∫41, ∫42, ∫43
Is different, and this is detected to identify the metal material.

Next, when identifying a metal having a similar material component, such as a metal material of the same kind, as shown in FIG. 6A, the impedance specific to the metal is detected as an XY address using a two-dimensional address map. . At this time, since the three kinds of phase and change values of the first to third metals a, b, and c of the same kind are all small and a large difference cannot be obtained, it is difficult to distinguish these three kinds of metals. The accuracy of discriminating is low.

Therefore, as shown in FIG.
The area mapped in the 0 ° area is narrowed down to a specific area specific to the metal material necessary for metal identification and specified, and this specific area is virtually replaced in a 90 ° space to obtain three types of metal. By distinguishing the state of change in the phase difference between a, b, and c, it is possible to easily extract the identification elements that are the features of each.

For example, as shown in FIG. 6C, when three kinds of metals a, b, and c are concentrated in a mapping region of 30 °, if these are re-mapped to 90 °, the phase difference becomes 3 °. A value suitable for discrimination is obtained by being doubled.

FIGS. 7A and 7B show experimental results obtained for various types of metal materials obtained as described above (measurement phase X =
0 °, Y = 90 °).

As a result, as shown in FIG. 7A, a stainless steel material having a high X value as a metal material suitable for the same kind of metal material which is an economical metal material and which contains different components in consideration of forgery prevention. Was confirmed, and it was recognized that stainless steel was preferable for the production of medals.

On the other hand, other than stainless steel, for example, as shown in FIG.
A high X value is recognized for royal gold. However,
Since these are expensive metal materials, they are not suitable for the material of the medal.

Further, the maximum rate of change at each measurement for each metal material shown in FIGS. 7A and 7B is shown in FIGS.
Shown in As a result, in stainless steels, austenitic stainless steels (304, 304L, 3L) were generally obtained except for ferrite-based SUS430 (Plate).
04S, 310S, 305, 316) show a high rate of change suitable for discrimination, and it is recognized that high discrimination accuracy can be obtained when austenitic stainless steel is applied to medals.

Therefore, since the above-mentioned stainless steel shows a remarkable value in the discriminating condition of the metal material, it is possible to discriminate medals having the same appearance shape with high accuracy even if a plurality of kinds of medals made of stainless steel having different components are produced. Can be. Also, 2
By preparing three medals made of stainless steel in the store and using only one medal, and setting different medals to be used for any given date, fraudulent use by forgery is completely prevented. can do. In addition, since each stainless steel is difficult to identify from the appearance, it is effective in preventing forgery, and can be plated to unify the appearance and shape.

Further, when such medals are commonly used as chain stores at a plurality of gaming stores, they can be used as highly reliable medals having forgery prevention established.
Since the production cost per medal is low and mass production is possible at low cost, a large number of medals can be operated stably. In addition, a mark dedicated to the own store is displayed on the front and back of the medal similarly to the existing medal, and is used as an advertising medium.

When operated as a game store system, the material sensors S are built in each of the slot machines 21a and counters 22a provided for each of the game stores 12a, 12b, 12c and so on. Medal M made of stainless steel issued by the company is a slot machine 2
1a... Or each counter 22a..., The material sensor S detects material data peculiar to stainless steel, detects it as an effective medal, and continuously uses it.

On the other hand, if a medal made of another metal material is used, it is detected as invalid and the transaction is stopped. At the same time, it may be set to notify the attendant of the fact. In this case, even if the same duplicated medals are used, even if the medals are apparently the same, the medals themselves are detected and identified, so that the medals can be reliably distinguished from the duplicated medals. Further, in the case of other store medals (usually a copper alloy system), similarly, since the material is different, it is possible to accurately distinguish between the own store medal and the other store medal.

Further, even if an attempt is made to forge a medal,
The type of metal used for the medal is not obvious at first glance, and even if it turns out that stainless steel is used as the material for the medal, one of a variety of similar stainless steels is selected and imitated. Is difficult and is very effective in preventing forgery.

Further, if one type of stainless steel specified in the existing JIS standard list is selected and used, a medal specific to the own store can be established. In addition, not only the specified stainless steel but also other elements can be contained or plated to enhance the forgery prevention performance.

Further, since stainless steel has a property that the magnetic permeability changes due to a difference in plastic working such as press working, even if the working conditions are changed, the identification element of the medal can be changed.

In correspondence between the present invention and the configuration of the above-described one embodiment, the game store of the present invention includes the first game store 12a, the second game store 12b, and the third game store 21c of the embodiment. , The game machine corresponds to each of the slot machines 21a to 21d, the counter corresponds to the first counter 22a, the second counter 22b, and the game medium corresponds to the medal M. Although the specific material and the same kind of metal material correspond to the stainless steel-based metal material, the present invention can be applied based on the technical idea described in the claims, and only the configuration of the above-described one embodiment is applied. However, the present invention is not limited to this.

[0041]

According to the present invention, since the material itself of the game medium is detected and identified, high identification performance can be obtained, and the game medium of the own store and the other game medium can be accurately distinguished. it can.
