Description

The present invention includes a game machine for executing a predetermined game, related to fraud detection apparatus for detecting fraud made to the gaming machine.

Slot machines and pachinko machines are known as gaming machines installed in the game hall.
In general, a slot machine has a plurality of symbols such as predetermined pictures, numbers, characters, etc. displayed on the outer peripheral surface by inserting a game medal as a game medium from a medal slot and pressing a start lever. Reels (usually three reels) start rotating, and after rotating at a constant speed, the stop button is pressed at an arbitrary timing to stop the reels, and depending on the combination of symbols on the reels displayed as stopped A gaming machine in which a predetermined number of medals are paid out from a medal payout exit.

  In addition, the pachinko machine is a gaming machine in which a player operates a launch handle to launch a game ball onto the board surface, and when the launched game ball wins a predetermined winning opening, a predetermined number of winning balls are paid out. It is.

In gaming machines represented by these slot machines and pachinko machines, there are cases where fraudulent acts as described below are performed.
For example, a small device that can generate static electricity with a simple operation, specifically an electronic lighter, is operated toward the front of the gaming machine to generate static electricity and apply a high voltage to the inside of the gaming machine. A large discharge current is allowed to flow through the arranged operation board, and further, a discharge current is caused to flow through the harness connected to the operation board to the main control board and the sub control board to induce malfunctions of the main control board, etc. There has been a case where an illegal act of illegally paying out a medal or the like as a medium has been performed.

Here, the malfunction of the main control board or the like may be, for example, that the control program is operated on the assumption that the present game state is higher than usual even though the present game state is not a game state in which the yield rate varies. , The credit card is not full, but it may be misrecognized as full. In either case, medals etc. are illegally paid out, resulting in loss of the game hall. It was a big problem.
Further, when a high voltage is applied by improperly generating static electricity, a large discharge current flows in the device circuit of the operation board, which may damage the operation board itself.

Therefore, as a technique for preventing damage due to such illegal acts, for example, it is conceivable to ground the control board (see Patent Documents 1 and 2).
Specifically, one end of a ground wire, which is a grounded coated electric wire, is connected to the control board, and the other end is connected to a housing or a frame of a gaming machine. As a result, static electricity charged on the control board can be removed, and adverse effects on the device circuit due to the static electricity can be prevented.

Hereinafter, preferred embodiments of a gaming machine and a fraud detection device according to the present invention will be described with reference to the drawings.
In addition, the fraud detection device of the present invention can detect fraudulent acts that illegally generate static electricity in the vicinity of a gaming machine and pay out the ball, and can be provided at any location in the gaming machine. It has become.
In the present embodiment, the basic configuration of the fraud detection device and the outline of the principle for detecting fraud are described first, and then the configuration of the gaming machine provided with the fraud detection device is described.

[Basic configuration and principle of fraud detection device]
The fraud detection device includes at least a thin film portion in which a predetermined material is formed as a thin film, and an adherend member to which the thin film portion is attached.
Here, a conductive material having high conductivity is used as a material for forming the thin film portion.
On the other hand, an insulating material having low conductivity is used as a material for forming the adherend member.
When static electricity with a large amount of charge is generated in the vicinity of the thin film portion and the adherend member having such a configuration, a phenomenon occurs in which the thin film portion is damaged. The following reason is presumed as the reason why such a phenomenon occurs.
Operate the fraudulent means in a state in which an improper means containing a static electricity generating object, for example, a piezoelectric element (herein referred to as a “charged body”) is brought close to the thin film portion and the adhered member. When static electricity is generated and the charged body is charged, the thin film portion formed of the conductive material is charged by electrostatic induction, and the adherend member formed of the insulating material is charged by dielectric polarization. Here, when the charge amount charged on the charged body is very large, the charge amount charged on the thin film portion also increases, and the charge amount charged on the adherend also increases. And since the electric charge charged to the thin film portion and the electric charge charged to the adherend member have the same polarity, the thin film portion and the adherend member repel each other due to the repulsive force of the Coulomb force, and the thin film portion is attached to the adherend member. The part with weak adhesion force is damaged by shearing and missing. In particular, the thin film portion is formed as a thin film and has a very small thickness. Therefore, the shear load that can be sheared is small, and it easily shears when an external force is applied even a little. For this reason, if the voltage of the static electricity generated improperly is high and the charge amount of the charged body, the thin film portion, and the adherend member increases, the repulsive force generated between the thin film portion and the adherend member is easy. When the shear load is exceeded, shearing of the thin film portion is easily caused.
By utilizing such a physical phenomenon, the thin film portion and the adherend member are arranged as a fraud detection device at an arbitrary place in the gaming machine, in particular, at a position that can be charged by static electricity generated in the vicinity of the gaming machine. As a result, the thin film part and the adherend are charged due to static electricity generated in the vicinity of the gaming machine, and the thin film part is damaged due to the repulsive force between them. It can be left as traces. Then, by confirming this trace by the store clerk of the amusement hall, it is possible to detect the occurrence of fraud afterwards.

The thin film portion is formed in a shape that can be damaged by charged static electricity in order to cause the above phenomenon more reliably.
For example, the thin film portion can be formed as a thin film with a thickness of nm units or μm units, and in particular, the thickness can be about 0.05 to 100 μm. Thus, by reducing the thickness of the thin film portion, the shear load required for shearing the thin film portion can be reduced. Therefore, the Coulomb force by the charged electric charge can easily exceed the shear load, and thereby the thin film portion can be more reliably damaged.
Moreover, the cross-sectional area of the thin film portion in the shear direction is made as small as possible. For example, when forming a thin film part in strip | belt shape (elongated rectangular shape), the width (length in a transversal direction) shall be 10 mm or less. By narrowing the width of the thin film portion in this way, the cross-sectional area in the shear direction of the thin film portion is reduced and the shear load is reduced, so that the thin film portion can be reliably damaged.
The width of the thin film portion is preferably set to 1 mm or more, for example, in order to make it easy to visually recognize the damaged portion of the thin film portion.
Further, the length of the thin film portion in the longitudinal direction can be arbitrarily determined. This is because the shear load is a quantitative value determined by the cross-sectional area of the thin film portion and is not affected by the length of the thin film portion.

As a material for forming the thin film portion, a material having a relatively high conductivity, for example, a metal or an alloy having a conductivity of 2.0 × 10 ⁶ [S / m] or more can be used. Specifically, for example, silver (conductivity: 61.4 × 10 ⁶ [S / m] (at 20 ° C.)), copper (59.0 × 10 ⁶ [S / m]), gold (45. 5 × 10 ⁶ [S / m]), aluminum (37.4 × 10 ⁶ [S / m]), zinc (16.9 × 10 ⁶ [S / m]), tin (7.9 × 10 ⁶ [S / m]) S / m]) and lead (4.8 × 10 ⁶ [S / m]), and alloys such as copper alloys, aluminum alloys, lead alloys, and zinc alloys can be used as the material for the thin film portion. . By forming a thin film portion using a material with high conductivity, the amount of charge charged by electrostatic induction can be increased, and the Coulomb force can be increased to easily damage the thin film portion. be able to.

The thin film portion having such a configuration is attached to a member to be attached formed of an insulating material having low conductivity. The adherend is formed using an insulating material having a low conductivity, for example, a material having a conductivity of 10 ⁻¹⁰ [S / m] or less. Specifically, for example, acrylic resin (conductivity: 10 ⁻¹³ [S / m] or less), celluloid (10 ⁻¹⁰ [S / m] or less), polyethylene terephthalate (10 ⁻¹¹ [S / m] or less) , Synthetic resins such as polycarbonate (10 ⁻¹⁶ [S / m] or less), ABS resin (10 ⁻¹² [S / m] or less), glass (10 ⁻¹² [S / m] or less), rubber (10 ⁻¹⁶ ) [S / m] or less), porcelain (10 ⁻¹⁴ [S / m] or less), or the like can be used as a material.
Further, it is desirable to use a material having a high dielectric constant for the adherent member in order to increase the amount of charge charged by dielectric polarization. The relative dielectric constant of each of the above materials is as follows. Acrylic resin (2.7 to 4.5), ABS resin (2.4 to 4.1), glass (5.4 to 9.9), rubber (2.0 to 3.5), porcelain (4. 4 to 7.0)

  In addition, although the material which forms a to-be-adhered member shall be an insulating material in this embodiment, it is not restricted to an insulating material, A conductive material can also be used. In this case, when static electricity is generated in the charged body, the member to be adhered is charged by electrostatic induction, and the Coulomb force acts between the member to be adhered and the thin film portion, so that the thin film portion can be damaged. .

In the above description, the thin film portion and the adherend are charged by being directly affected by the charged body in which static electricity is generated. However, the present invention is not limited to being directly affected, but indirectly. It can also be configured to receive and charge.
For example, when an inclusion is interposed between the thin film portion and the adherend and the charged body, the charge is charged by electrostatic induction or dielectric polarization when the charged body is charged. Here, in the case where the charge charged at a location near the inclusion in the charged body is a negative charge, a positive charge is charged at a location near the charged body in the inclusion, and a negative charge is charged at a location far from the charged body. To do. And a thin film part and a to-be-adhered member are electrically charged by the negative charge electrically charged by the inclusion.
As described above, even when the inclusion is interposed between the thin film portion and the adherend member and the charged body, the thin film portion and the adherend member are indirectly charged by charging the charged body. And when there is much charge amount charged to the charging body, the repulsive force which arises between the charged thin film part and a to-be-adhered member becomes large, and a thin film part is damaged.

Up to this point, the thin film portion and the adherend member constituting the fraud detection device have been described. However, the fraud detection device may be configured such that a coating layer is further laminated on the surface of the thin film portion.
The coating layer is formed of a material having a predetermined melting point, particularly a material having a relatively low melting point. The coating layer is dissolved by conduction of Joule heat generated in the thin film portion.
That is, when the thin film portion is charged by electrostatic induction, electrons move along with the charging and current flows. This current causes Joule heat to be generated in the thin film portion, and this Joule heat is conducted to form the coating layer. Heat up and dissolve.
Using this phenomenon, a thin film portion, a member to be adhered, and a coating layer are provided as a fraud detection device at an arbitrary location in the gaming machine. Thereby, when static electricity is illegally generated in the vicinity of the gaming machine, the thin film portion is charged and a current flows to generate Joule heat. This Joule heat is conducted and the coating layer is dissolved. As a result, the dissolved state can be left as a trace of fraud, and the store clerk at the amusement hall can recognize the occurrence of the fraud by checking the trace.

Note that the coating layer is desirably formed of a material having a relatively low melting point, for example, a material having a melting point of 250 ° C. or lower. Specifically, acrylic resin (melting point: 80-105 ° C.), acrylonitrile butadiene styrene (ABS resin) (70-110 ° C.), nitrocellulose (171 ° C.), vinyl chloride resin (180 ° C.), polystyrene resin (230 ° C.) ) Or the like can be used as a material for the coating layer.
In addition, the coating layer can be provided in the vicinity of the thin film portion that can conduct Joule heat generated in the thin film portion, rather than being laminated on the surface of the thin film portion.

Furthermore, it is desirable to form the thin film portion using a material having a small specific heat capacity so that the coating layer can be melted.
Specific examples of the material having a small specific heat capacity include, for example, lead (128 [J / kg · K]), gold (129 [J / kg · K]), tin (228 [J / kg · K]), silver (232 [J / kg · K]), copper (385 [J / kg · K]), zinc (389 [J / kg · K]), and the like.

As described above, the thin film portion is preferably formed of a material having a small specific heat capacity in consideration of melting of the coating layer, and, as described above, in order to increase the amount of charge to be charged, It is desirable to form with a material with high electrical conductivity. In addition, since the thin film portion is formed into a thin film, it is desirable to form the thin film portion with a highly malleable material or a material that can be vapor-deposited. It is desirable to form.
The thin film portion is formed using a material that satisfies these conditions to the maximum. Further, the thin film portion is formed in a shape having a small cross-sectional area in order to make the shear load that can be sheared as small as possible. As a result, the thin film portion can be damaged by charged static electricity.

Furthermore, the fraud detection device can be configured to provide a sheet metal made of a predetermined conductive material at a position close to the thin film portion.
The sheet metal is a current promoting member for promoting the movement of electrons due to electrostatic induction generated in the thin film portion.
Details of the function of the sheet metal will be further described. Even when the sheet metal is not provided, when static electricity with a large amount of charge is generated in the charged body, the thin film portion and the adherend are charged, repulsive force acts, and the thin film portion is damaged. Here, although the thin film portion is formed of a material having high conductivity, it is formed in a thin film shape for easy breakage. For this reason, the electrical resistance is high, the moving electrons are reduced accordingly, the amount of Joule heat generated is reduced, and thereby the time until the coating layer is dissolved is delayed. Therefore, a sheet metal made of a material having high conductivity and low electrical resistance is provided at a position in contact with or close to the thin film portion. As a result, electrostatic induction occurs in the sheet metal due to the charging of the thin film portion, and charging occurs, and a discharge occurs between the thin film portion and the sheet metal, so that the electrons in the thin film portion move to the sheet metal and the electrons are reduced. In order to maintain electrical balance inside the part, electrons move further and the current increases, so the amount of Joule heat generated increases accordingly, and the temperature rise of the coating layer is accelerated. Thereby, since a coating layer breaks early, the trace of a fraudulent act can remain reliably.

Note that as a material for forming the sheet metal, a metal having a relatively high conductivity, for example, a metal having a conductivity of 2.0 × 10 ⁶ [S / m] or more can be used. Specific examples include copper (conductivity: 59.0 × 10 ⁶ [S / m] (at 20 ° C.)) and iron (9.9 × 10 ⁶ [S / m]). .

The above is the outline of the basic configuration of the fraud detection device and the principle of detecting fraud. The fraud detection device having such a configuration can be provided at any location in the gaming machine, but as a specific example, the location where the thin film portion is damaged is easily visible, for example, at a gaming machine. It can be provided on the middle panel mounted in the middle of the front of a certain slot machine.
Hereinafter, the configuration of the gaming machine in which the fraud detection device is provided on the middle panel will be described.

Further, the front door 1a is provided with a display window 6 on the upper side of each operation means for allowing the symbols displayed on the reels 41a, 41b, 41c to be visually recognized. Moreover, the speaker 8 from which a sound effect, a sound, etc. are output is provided in the upper part and the lower part of the front door 1a.

In the center of the housing 1b, a drum unit 4 including reels 41a, 41b, and 41c, a motor (not shown) that rotates each of the reels 41a, 41b, and 41c, a sensor that detects a rotation position, and the like is provided.
In addition, a medal payout device 7 for storing and paying out medals is provided at the lower part of the housing 1b. The medal payout device 7 is provided with a hopper 7a for storing medals. The medal inserted from the medal slot 2 is detected by the medal selector 2b and guided to the hopper 7a.

  The main controller 9a is composed of a main board on which a control chip in which a main CPU, main ROM, main RAM and the like are integrated, a board case for housing the main board, and the like. Based on the signal from the medal selector 2b, each device such as the drum unit 4 and the medal payout device 7 is controlled to advance the following slot machine game.

Specifically, when a player inserts a medal from the medal insertion slot 2, the medal is detected by the medal selector 2b, and a detection signal is input to the main control unit 9a. When the bet button 2a is operated, the operation signal is input to the main controller 9a. The main controller 9a monitors the number of medals that can be played from the presence or absence of these signals and monitors the operation of the start lever 3.
When the start lever 3 is operated when the number of medals that can be played is reached, the main control section 9a controls the drum units 4 to rotate and rotate the reels 41a, 41b, 41c.

  Further, when the start lever 3 is operated, the main control unit 9a performs an internal lottery to draw a winning target of the current game from among a plurality of lottery targets of a bonus combination, a small combination, a replaying combination, and a loser, Based on the timing at which the stop buttons 5a, 5b, 5c are pressed, stop control of the rotating reels 41a, 41b, 41c is performed so as to stop at a combination of symbols according to the lottery result.

  Further, the main control unit 9a determines a combination of symbols that are stopped and displayed on the reels 41a, 41b, and 41c, and controls to pay out a predetermined number of medals to the medal payout device 7 when the combination is a predetermined symbol. Then, the medal is paid out from the medal payout opening 7b.

  In the slot machine 1 in which a game is executed with such contents, static electricity is illegally generated from the front of the slot machine 1 toward the front door 1a, and discharged to a control board or the like provided on the back surface of the front door 1a. There is a case in which a current is caused to flow and a discharge current is caused to flow to the control board of the main control unit 9a connected to the control board, thereby causing an erroneous operation of the main control unit 9a and illegally paying out medals. is there.

Therefore, in order to be able to detect such fraudulent activity, the thin film portion 16 formed by using a predetermined conductive material at a predetermined location in the slot machine 1 is provided as a fraud detection device. Thereby, when the static electricity is illegally generated, the thin film portion 16 is damaged, and the damaged state can be left as a trace of the occurrence of the fraud, and the illegal act generated by visually recognizing the trace is known. It is possible.
Here, the thin film portion 16 can be provided at an arbitrary position in the slot machine 1. As a specific example thereof, for example, the middle panel portion mounted in the middle of the back surface of the front door 1 a in the slot machine 1. 10 may be provided with a thin film portion 16.
The configuration of the middle panel portion 10 to which the thin film portion 16 is attached will be described with reference to FIGS.

[Middle panel]
The middle panel portion 10 is a mounting part that is mounted on the front door 1a of the slot machine 1 above the operation means including the medal insertion slot 2 and the like. As shown in FIGS. And a frame 12 that supports the middle panel 11, an insertion member 13 provided at the lower part of the front side 12 a of the frame 12, and a sheet metal 14 provided at the lower part of the front side 12 a of the frame 12. ing.

  The middle panel 11 is a rectangular plate-shaped member, and as shown in FIG. 6, a transparent plate 15 formed of a transparent material, a thin film portion 16 attached to the back side 15b of the transparent plate 15, and a transparent plate 15 has a structure in which a pattern layer 17 formed on the back side 15b of the film 15 and a coating layer 18 formed on the back side 15b of the transparent plate 15 so as to cover the thin film portion 16 and the pattern layer 17 are laminated. .

The transparent plate 15 is a rectangular plate-shaped member made of a transparent material. The transparent plate 15 functions as a member to be adhered because the thin film portion 16 is adhered thereto.
As the material for forming the transparent plate 15, the materials described above as the material of the adherend member, for example, synthetic resins such as acrylic resin, celluloid, polyethylene terephthalate, polycarbonate, cellulose acetate butyrate, cellulose tributyrate, etc., should be used. Can do. Further, tempered glass can be used for the transparent plate 15.

The thin film portion 16 is a member formed into a thin film using a predetermined conductive material.
The thin film portion 16 is desirably formed of a metal or alloy material having a high electrical conductivity, a material having a small specific heat capacity, a material having a low shear stress, a material having a high malleability, or a material that can be deposited.

The shape of the thin film portion 16 can be arbitrarily determined. In the present embodiment, the shape is a combination of an annular portion 16a formed in an annular shape and a linear portion 16b formed in a linear shape.
The annular portion 16a is a portion arranged along the periphery of the through hole 15c formed in the transparent plate 15, and has an inner diameter that is substantially the same as the diameter of the through hole 15c. The annular portion 16a can be formed in an arbitrary number in one thin film portion 16. In FIG. 6, the same number (two) as the through holes 15c are formed.
The straight portion 16b is a straight portion extending from the annular portion 16a.

In the present embodiment, the thin film portion 16 has a shape in which the annular portion 16a and the straight portion 16b are combined. However, the shape is not limited to such a shape, and for example, a pattern printed as the pattern layer 17 It can be formed into a shape that matches the shape, pattern, or the like, or a shape that constitutes a part of the pattern.
1, 4, 5, and 8, the thin film portion 16 is illustrated by a solid line. This is because the thin film portion 16 formed on the back side 15 b of the transparent plate 15 is the transparent plate. 15 indicates that it can be visually recognized.

When the static electricity is generated in the direction from the outside of the slot machine 1 toward the front door 1a, the thin film portion 16 is damaged by the influence of the static electricity.
The reason for the damage is estimated as follows. In the vicinity of the slot machine 1, an illegal means such as an electronic lighter is operated to generate high-voltage static electricity in the built-in piezoelectric element. When the piezoelectric element is charged with a large amount of charge, it is formed of a conductive material. The formed thin film portion 16 is charged by electrostatic induction, while the transparent plate 15 formed of an insulating material is charged by dielectric polarization. Since the electric charge charged to the thin film portion 16 and the electric charge charged to the transparent plate 15 have the same polarity, the thin film portion 16 and the transparent plate 15 repel each other due to the repulsive force of the Coulomb force, and the thin film portion 16 becomes the transparent plate. Trying to leave 15 Here, when the thin film portion 16 is bonded to the transparent plate 15 with an adhesive (not shown), the adhesive is caused by the heat conduction of Joule heat generated by the movement of electrons accompanying charging of the thin film portion 16. Dissolve. When the temperature of the adhesive is increased and the adhesive strength is weakened, the portion of the thin film portion 16 formed with the thin film is weakened due to shearing.

When the thin film portion 16 is damaged in this manner, the damaged state remains as a trace that supports the occurrence of unauthorized static electricity, so that an illegal act can be discovered afterwards.
Further, the thin film portion 16 has a shape in which the annular portion 16a and the straight portion 16b are combined and is formed in a wide range in the lower portion of the transparent plate 15, so that the slot machine 1 is viewed from the front side. The damaged portion of the thin film portion 16 can be easily visually recognized through the transparent plate 15 (see FIG. 8).

  Furthermore, the thin film portion 16 is formed in a shape that reduces the cross-sectional area in order to facilitate breakage. For example, the thickness of the thin film portion 16 is very thin. Moreover, the width | variety between the internal diameter and outer diameter in the annular part 16a is narrow. Furthermore, the width of the straight portion 16b is also narrowed. By forming in such a shape, since the cross-sectional area of the thin film part 16 becomes small, a shear load becomes small and shearing becomes easy.

In addition, by adjusting the thickness of the thin film portion 16, it is possible to change the amount of static electricity necessary for breakage and the voltage value. For example, when the thickness of the thin film portion 16 is increased, the cross-sectional area is increased and the shear load is increased, so that the amount of static electricity necessary for breakage is increased and the voltage value is increased. On the other hand, if the thickness of the thin film portion 16 is reduced, the cross-sectional area is reduced and the shear load is reduced, so that the amount of static electricity necessary for breakage is reduced and the voltage value is lowered. Therefore, when the thickness is selected according to the amount of charge of the static electricity generated improperly or the voltage value of the static electricity, and the thin film portion 16 is formed with the selected thickness, the thin film portion 16 when the static electricity is generated at the voltage value. Can be reliably detected from the occurrence of static electricity.
Further, not only the thickness of the thin film portion 16 but also, for example, by adjusting the material of the thin film portion 16, the amount of static electricity necessary for breakage and the voltage value can be changed. The reason is the same as in the case of thickness, and the shear load can be changed by changing the material.

In addition, as a method of attaching the thin film portion 16 to the transparent plate 15, for example, there is a method by hot stamping (foil pressing).
Hot stamping is a processing method in which the metal foil that becomes the thin film portion 16 is transferred to the transparent plate 15 by pressurization or heating.
In this hot stamping, an adhesive suitable for the material of the metal foil is selected, and this adhesive is pre-applied to the surface of the metal foil or the surface of the transparent plate 15, and by pressing a hot platen from the back of the metal foil, The thin film portion 16 can be transferred to the transparent plate 15.

The pattern layer 17 is a pattern layer formed by printing using colored ink. By forming the pattern layer 17, a predetermined pattern is applied to the middle panel 11.
Here, as shown in FIGS. 5 and 6, the transparent plate 15 is divided into a display window corresponding portion 15d corresponding to the opening 12c of the frame body 12 and a printing portion 15e which is a portion other than the display window corresponding portion 15d. In this case, the predetermined pattern as the pattern layer 17 is printed on the printing unit 15e. In addition, the display window corresponding portion 15d displays a winning line for determining whether or not the symbols of the reels 41a, 41b, and 41c displayed on the display window 6 are displayed as combinations of symbols corresponding to winning combinations (see FIG. (Not shown) is printed as the picture layer 17. In the printing unit 15e, printing called so-called “whitening” is performed, in which transparent portions formed in the gaps between the patterns are painted white. Thereby, when the slot machine 1 is viewed from the front, the frame body 12 cannot be visually recognized through the printing unit 15e. On the other hand, in the display window corresponding portion 15d, the transparent state of the transparent plate 15 is maintained except that a winning line is printed. Thereby, when the slot machine 1 is viewed from the front, the symbols of the reels 41 a, 41 b, 41 c are visible through the display window 6.

For example, a printing technique such as silk screen printing or offset printing can be used to form the pattern layer 17.
Silk screen printing is a technique in which silk cloth or the like is used as a plate material, an appropriate amount is pushed out by rubbing ink, and the ink is placed on a printed matter. Offset printing refers to a method of transferring ink to a printed material through a blanket formed of rubber or the like.
However, the pattern layer 17 is not limited to printing by a method such as silk screen printing. For example, the pattern layer 17 is applied by attaching a film on which the pattern is drawn to the back side 15b or the front side 15a of the transparent plate 15. Layer 17 can also be formed.
Further, in FIG. 6, the pattern layer 17 is printed on the back side 15 b of the transparent plate 15, but is not limited to the back side 15 b, and is printed on the front side 15 a of the transparent plate 15. You can also In this case, it is desirable to form a protective layer for protecting the pattern layer 17 on the surface of the pattern layer 17.

The coating layer 18 is a layer formed on the back side 15 b of the transparent plate 15 and is a protective layer for protecting the thin film portion 16 and the picture layer 17.
The coating layer 18 is formed using a material having a relatively low melting point, and, like the thin film portion 16, when an act of generating static electricity and illegally paying out medals occurs, The fact can be left as a trace.
This phenomenon will be described in detail.
Static electricity is generated outside the slot machine 1 and the thin film portion 16 is charged. When electrons move and current flows along with this charging, Joule heat is generated in the thin film portion 16 and contacts the thin film portion 16. The coating layer 18 is melted by heating due to the Joule heat conduction.
Here, when the thin film portion 16 is formed of a metal or alloy such as gold or silver, Joule heat is generated in the entire thin film portion 16. Therefore, the entire portion of the coating layer 18 that is in contact with the thin film layer 16 is heated and dissolved (see FIG. 9).
The dissolved portion of the coating layer 18 remains in a dissolved state after that. For this reason, the clerk at the amusement hall can know that the fraud has occurred by checking the dissolved state.

  The range in which the coating layer 18 is laminated on the back surface 15b of the transparent plate 15 may be the entire back surface 15b of the transparent plate 15 or a part thereof. In some cases, it is desirable to laminate at least the portion where the thin film portion 16 is formed and the periphery thereof.

In addition, since phenomena such as breakage and dissolution caused by the generation of static electricity occur in both the thin film portion 16 and the coating layer 18, for example, the coating layer 18 is not formed, and only the thin film portion 16 is provided to detect fraud. It is also possible to perform. However, it is desirable to form not only the thin film portion 16 but also the coating layer 18 in order to make it easy to confirm traces such as breakage. This is because there is a difference in the scale of the trace when the thin film portion 16 and the coating layer 18 are compared.
For example, in the thin film portion 16, the number of breakage points is about one or two, so the scale of breakage is small. On the other hand, the range in which the coating layer 18 is dissolved is almost the portion in contact with the thin film portion 16, and thus the scale of dissolution is large (see FIG. 9). In such a situation, even if one place of the thin film portion 16 is damaged and the store clerk of the game hall is unaware of this, the large-scale dissolved state formed in the coating layer 18 can be reliably recognized, You can be sure that fraud has occurred. Therefore, it is desirable to laminate the coating layer 18 at least on the surface of the thin film portion 16.

In addition, when the coating layer 18 is laminated | stacked on the surface of the thin film part 16, even if it tries to shear by applying a repulsive force to the thin film part 16, since the coating layer 18 is located in the shear direction, it does not shear in this state . When the coating layer 18 starts to dissolve and the coating layer 18 contracts and solidifies in a direction away from the thin film portion 16, and the coating layer 18 is no longer positioned in the shear direction of the thin film portion 16, the thin film portion 16. Shear occurs.
Moreover, in the coating layer 18, the charge amount and voltage value of the static electricity which melt | dissolve can be changed by adjusting the thickness and material. For example, when the thickness of the coating layer 18 is increased, the amount of Joule heat necessary for melting increases, the amount of current necessary for generating this amount of heat increases, and the amount of static electricity necessary to flow the current. And the voltage value becomes high. On the other hand, when the thickness of the coating layer 18 is reduced, the amount of Joule heat necessary for melting decreases, the amount of current necessary for generating this amount of heat decreases, and the amount of static electricity necessary to flow the current. And the voltage value becomes low. Therefore, the thickness or material (melting point in the case of a material) is selected according to the amount of static charge generated illegally or the voltage value of the static electricity, and the coating layer 18 is formed with the selected thickness or material. Since the coating layer 18 dissolves when static electricity is generated at a voltage value, the generation of the static electricity can be reliably detected.

The intermediate panel 11 in which the transparent plate 15, the thin film portion 16, the pattern layer 17, and the coating layer 18 are laminated is fitted into a frame body 12 formed in a rectangular frame shape, and the back surface of the front door 1 a of the slot machine 1. Attached to.
The frame 12 is a rectangular frame member for supporting the plate-shaped middle panel 11 from the periphery thereof, and the center of the rear surface of the front door 1a in a state where the middle panel 11 is fitted to the front side 12a. Attached to the part.

A horizontally long rectangular opening 12 c is formed at the center of the frame 12, and this opening 12 c is configured as a display window 6 located at the center of the front door 1 a of the slot machine 1. Through the opening 12c, the symbols of the reels 41a, 41b, 41c are visible.
A member housing portion 12d for fitting the insertion member 13 and a sheet metal housing portion 12e for fitting the sheet metal 14 are formed in the lower portion of the front side 12a of the frame body 12.

The insertion member 13 is a plate-like member formed of a material having low conductivity, for example, a synthetic resin such as acrylic resin, and is a member storage portion formed at the lower portion of the front side 12a of the frame body 12 12d.
A cylindrical or columnar protruding portion 13a having an upper surface 13b is formed in the middle of the plate-shaped insertion member 13. The protruding portion 13 a is inserted into a through hole 15 c formed in the transparent plate 15.

A through hole 15c is formed in the transparent plate 15 from the front side 15a to the back side 15b. The reason is that the thin film portion 16 is easily affected by static electricity in the annular portion 16a.
The role of the through hole 15c will be further described. When the through hole 15 c is not formed in the transparent plate 15, the thin film portion 16 attached to the back side 15 b of the transparent plate 15 is not in communication with the front side 15 a of the transparent plate 15. Here, when static electricity is generated outside the slot machine 1, since the transparent plate 15 is interposed between the static electricity and the thin film portion 16, the influence of static electricity on the thin film portion 16 is reduced. If it does so, it will become difficult to charge the thin film part 16, and it will become difficult to detect fraud.
On the other hand, when the through-hole 15c is drilled in the transparent plate 15 and the annular portion 16a of the thin film portion 16 is disposed around the through-hole 15c, the annular portion 16a of the thin film portion 16 and the front side 15a of the transparent plate 15 are provided. Are in communication with each other through the through-hole 15c. Therefore, when static electricity is generated outside the slot machine 1, the influence of the static electricity reaches the annular portion 16a of the thin film portion 16 through the through-hole 15c. If it does so, the thin film part 16 will be electrically charged and it will become easy to break, and it will become possible to detect an illegal act.

  However, if the through hole 15c is formed in the transparent plate 15, the frame body 12 can be seen through the through hole 15c when the through hole 15c is viewed from the front of the slot machine 1. Therefore, the insertion member 13 is provided at a position where the through hole 15c can be closed, and the projecting portion 13a of the insertion member 13 is inserted into the through hole 15c. Thereby, since the through-hole 15c is obstruct | occluded, the visual recognition of the frame 12 can be prevented.

In addition, in this embodiment, although the shape of the protrusion part 13a of the penetration member 13 is made into cylindrical shape or column shape, it is not restricted to these shapes, According to the content of the pattern printed as the pattern layer 17 It can be formed into a shape.
Moreover, although the two insertion members 13 are provided in FIG. 1 etc., it is not restricted to two, Arbitrary numbers can be provided.
Furthermore, in FIG.4, FIG.5, FIG.7, although the penetration member 13 is provided in the lower middle part of the front side 12a of the frame 12, it does not restrict to providing in this position, For example, a frame It can be provided at an arbitrary position in the lower part of the front side 12a of the body 12, or a circular through hole is formed in the lower part of the frame body 12, and the insertion member 13 is inserted into the through hole from the back side 12b of the frame body 12. It is also possible to insert the protruding portion 13a.

The sheet metal 14 is a plate-shaped small piece formed of a material having high conductivity, for example, a metal material such as copper or iron.
The sheet metal 14 is fitted into a sheet metal storage part 12 e that is recessed in the lower part of the front side 12 a of the frame 12.
When the middle panel 11 is fitted to the frame body 12 to which the sheet metal 14 is fitted, the end of the thin film portion 16 and the sheet metal 14 are arranged to face each other via the coating layer 18 (FIG. 7). reference). FIG. 7 is a view for clearly showing the positional relationship between the insertion member 13 and the sheet metal 14 and the thin film portion 16 that are fitted to the lower portion of the frame body 12. For this reason, the configuration of the middle panel 11 other than the thin film portion 16 (for example, the coating layer 18 and the like) is omitted.

The reason for providing the sheet metal 14 is to promote the movement of electrons due to electrostatic induction generated in the thin film portion 16.
The reason will be described in detail.
Although the thin film portion 16 is formed of a material having high electrical conductivity, the thin film portion 16 is formed to facilitate breakage. For this reason, the electrical resistance is high, the moving electrons are reduced by that amount, the amount of Joule heat generated is reduced, and thereby the time until the coating layer 18 is dissolved is delayed. Therefore, the sheet metal 14 formed of a material having high conductivity and low electrical resistance is provided in the vicinity of the thin film portion 16. As a result, electrostatic induction occurs in the sheet metal 14 due to the charging of the thin film portion 16, charging occurs, and discharge occurs between the thin film portion 16 and the sheet metal 14, and electrons in the thin film portion 16 move to the sheet metal 14. Further, since electrons move further inside the thin film portion 16 where electrons have decreased and the current increases, the generation amount of Joule heat increases accordingly, and the temperature rise of the coating layer 18 is accelerated. Thereby, since the coating layer 18 is damaged at an early stage, it is possible to reliably leave a trace of fraud.

  The above is the reason why the sheet metal 14 is provided. However, the sheet metal 14 is not simply provided in the vicinity of the thin film portion 16, but is located farthest from the annular portion 16a at a position corresponding to the end of the thin film portion 16, particularly in the thin film portion 16. It is provided at a position corresponding to the end of the straight line portion 16b. The reason is that when static electricity is generated in the vicinity of the slot machine 1, a positive charge is charged in the annular portion 16 a and a negative charge is charged in the end portion of the linear portion 16 b. This is because more current flows through the thin film portion 16 by letting it escape to the sheet metal 14.

  In the present embodiment, the thin film portion 16 and the sheet metal 14 are disposed at the lower portion of the frame body 12, but when the middle panel portion 10 is mounted in the middle of the back surface of the front door 1 a, A lower part comes to be located directly above operation means, such as medal slot 2 and stop button 5a, 5b, 5c arranged at the front side of front door 1a (refer to Drawing 1). For this reason, an illegal act that generates static electricity for the medal slot 2 or the like can be reliably detected by the damage of the thin film portion 16.

  Further, the thin film portion 16 and the sheet metal 14 are close to each other through the coating layer 18. For this reason, when a discharge occurs between the thin film portion 16 and the sheet metal 14, the coating layer 18 positioned therebetween is damaged.

Further, in FIG. 5 and the like, only one sheet metal 14 is provided, but the number is not limited to one, and a plurality of sheets can be provided.
In FIG. 7, the sheet metal 14 is configured to be provided on the lower right side of the front side 12 a of the frame body 12. However, the position where the sheet metal 14 is provided is not limited to the position. For example, the frame body 12 is provided. It can be provided at any location that can contact or approach the thin film portion 16 such as the lower left side of the front side 12a.

The above description describes the configuration in which the thin film portion 16 and the like are provided in the middle panel portion 10 as a fraud detection device. However, the thin film portion 16 and the like are not limited to being provided in the middle panel portion 10, and a gaming machine It can be provided at any location.
Further, when the thin film portion 16 or the like is provided at an arbitrary position in the gaming machine, the thin film portion 16 or the sheet metal 14 can be formed as an integrated fraud detection device 20 and provided in the gaming machine. . The configuration of the integrated fraud detection device 20 will be described with reference to FIGS.

[Injustice detection device]
As shown in these drawings, the fraud detection device 20 includes a thin film portion 21 formed in a thin film using a conductive material, a sheet metal 22 that is a plate-shaped piece formed of a material having high conductivity, and the thin film portion 21. And a base 24 that is a base member formed in order to integrate the thin film portion 21, the sheet metal 22, and the coating layer 23.

The base 24 includes a plate-like portion 24 a on which the thin film portion 21 is attached and the coating layer 23 is formed, and a metal plate support portion 24 b that supports the metal plate 22.
Here, the plate-like portion 24a functions as a member to be attached to which the thin film portion 21 is attached, and is formed using an insulating material. In the base 24, only the plate-like portion 24a may be formed of an insulating material, or the entire base 24 may be formed of an insulating material.
Further, when the thin film portion 21 is transferred to the plate-like portion 24a by a method such as hot stamping, the coating layer 23 is formed on the entire surface of the plate-like portion 24a to which the thin film portion 21 is transferred. At this time, the end portion of the thin film portion 21 is exposed without being covered with the coating layer 23.
The sheet metal support portion 24 b supports the sheet metal 22 by locking the hook-shaped portion of the locking portion 24 c formed in a hook shape to the sheet metal 22. At this time, the sheet metal 22 and the coating layer 23 can be brought into contact or close to each other.

By providing the fraud detection device 20 having such a configuration at an arbitrary position in the slot machine 1, static electricity generated outside the slot machine 1 is detected, and the result of the detection is determined based on damage to the thin film portion 21 or the coating layer 23. Can be left as dissolution traces.
That is, when the static electricity is generated illegally outside the slot machine 1, the thin film portion 21 is charged by electrostatic induction, and the plate-like portion 24a of the base 24 is charged by dielectric polarization, and the thin-film portion 21 and the plate-like portion are charged. The repulsive force of Coulomb force acts between 24a and the thin film part 21 is damaged. Further, when Joule heat is generated by the current flowing through the thin film portion 21, the Joule heat is conducted to the coating layer 23, and the coating layer 23 is dissolved. Since the damaged state of the thin film portion 21 and the dissolved state of the coating layer 23 remain as traces of fraud, it is possible to know that fraud has occurred by visually recognizing the traces.
Furthermore, since the sheet metal 22 is provided, a discharge occurs between the thin film portion 21 and the sheet metal 22, and a current further flows in the thin film portion 21, so that the generation of Joule heat is promoted and the coating layer 23 is accelerated. Dissolve.

Note that the overall size of the fraud detection device 20 can be arbitrarily determined. However, since the fraud detection device 20 is provided inside the slot machine 1, it is desirable that the fraud detection device 20 has a size that can be attached to the back surface of the front door 1a or can be stored inside the housing 1b.
Further, the fraud detection device 20 is provided inside the slot machine 1, and in particular, a part that is targeted when illegally generating static electricity, for example, the medal slot 2, the stop buttons 5 a, 5 b, 5 c It is desirable to provide in the vicinity of the start lever 3 and the like.

  Further, the fraud detection device 20 can be formed with an attachment portion (not shown) for enabling the fraud detection device 20 to be attached to the inside of the slot machine 1. Specific examples of the mounting portion include, for example, a screw hole for screwing the fraud detection device 20 into the inside of the slot machine 1 using a screw or the like, or a concave or convex shape formed in the slot machine 1. And a hook-like locking portion (latch) formed so as to be locked to the portion. By forming the attachment portion having these shapes on the base 24 of the fraud detection device 20 or the like, the fraud detection device 20 can be attached to a predetermined location of the slot machine 1.

As described above, according to the gaming machine and fraud detection device of the present embodiment, if the static electricity is generated toward the gaming machine illegally, the thin film portion is damaged, and this damaged state remains as a trace of fraud. , Can detect the fraud.
On the other hand, the conventional method of grounding the control board only has the effect of preventing static electricity charged on the control board and preventing damage to the device circuit, and the effect of detecting the executed fraud. Can't get.
In other words, the above-described method allows the static electricity charged on the control board to escape as a current to the ground, and the current only flows to the conductor of the ground wire, and there is no change in the appearance of the ground wire. If a store clerk at the amusement hall only sees the ground wire, it cannot know that a current has flowed, and cannot determine whether or not an illegal act has been performed.
As a result, if a fraudulent act is performed, the fraudulent act may be overlooked without being detected, and after that, the ball may be illegally paid out to increase the loss of the game hall.

The preferred embodiments of the gaming machine and the fraud detection device of the present invention have been described above. However, the gaming machine and the fraud detection device according to the present invention are not limited to the above-described embodiment, and various within the scope of the present invention. Needless to say, it is possible to implement this change.
For example, in FIG. 1, the thin film portion is formed on the middle panel, but the location where the thin film portion is formed is not limited to the middle panel, and is formed on, for example, the lower panel mounted below the operation means. be able to.
