Description

  The present invention relates to a fraud prevention device in a gaming machine that prevents fraudulent acts using magnetism such as magnets.

  2. Description of the Related Art Conventionally, in gaming machines such as pachinko machines, a fraudulent act has been performed in which a pachinko ball falling on a gaming board is guided to a winning opening of a winning device by a magnet to obtain a prize ball. In particular, recently, a pachinko ball (about 0.4 mm larger than the normal size) that is slightly larger than the regular size (diameter 11 mm), which is commonly referred to as a deka ball, is used to guide the deca ball to the prize opening using a magnet. There are frequent fraudulent acts of winning a prize and then radiating electromagnetic waves during a big hit game to obtain a large number of pachinko balls.

  This fraudulent action uses a count sensor (proximity switch) to detect a pachinko ball that has won a prize from the winning opening of each winning device placed on the game board, and to pay out the award ball by the number of detected pachinko balls. To be executed. Specifically, each winning device is provided with the above-described count sensor, and this fraudulent act is achieved by winning a desired winning device (a winning device having the largest number of winning balls is particularly effective) by using a big ball as a magnet. A large number of pachinko balls are illegally obtained by winning a prize in the mouth and stopping the big ball on the count sensor and then irradiating electromagnetic waves during a big hit game or the like.

  The count sensor has a circular hole (diameter of about 11.2 mm) slightly larger than a regular-sized pachinko ball. By passing the pachinko ball through the circular hole and detecting a magnetic change, that is, an output transistor Is configured to detect a pachinko ball by turning on and off. Therefore, when the big ball is guided to the winning opening of the desired winning device with a magnet and won, the big ball is caught in the circular hole of the count sensor provided in the winning device and then stops. When an electromagnetic wave is applied to a prize-winning device where a big ball is stopped, a malfunction occurs in which the output transistor of the count sensor repeatedly turns on and off, and as a result, a large amount of pachinko balls are paid out and illegally acquired. . In other words, a malicious player can use a magnet in this way to temporarily stop the big ball on the count sensor of the desired winning device, and then irradiate the winning device with electromagnetic waves at any time. A large amount of pachinko balls can be easily acquired.

  Therefore, a magnetic sensor for detecting that a magnet as disclosed in Patent Document 1 is used is attached to a game board of a pachinko machine, or an electromagnetic wave as disclosed in Patent Document 2 is irradiated. It is conceivable to prevent such improper behavior by attaching an electromagnetic wave sensor for detecting the above to a game board of a pachinko machine.

  However, if a normal magnetic sensor is provided alone, its detection range is limited, and as a result, the use of a magnet may not be detected accurately. There is a problem that the cost increases when the sensor is provided. Furthermore, the magnetic sensor may malfunction due to driving of an electromagnetic device such as a solenoid often used in gaming devices.

  In addition, electromagnetic sensors generally have a limited frequency band. Depending on the frequency, it may not be possible to detect unauthorized electromagnetic waves. Especially in high frequency bands such as gigahertz, the straightness of electromagnetic waves becomes stronger, and the location where the electromagnetic wave sensor is attached. There is a problem that some electromagnetic waves cannot be detected. In addition, it is difficult to distinguish between normal electromagnetic waves emitted from gaming machines and other devices, such as mobile phones, and electromagnetic waves emitted for fraud, and false detections that make normal electromagnetic waves illegal There is also a risk.

A pachinko ball is detected by detecting the change in magnetism through the passage, that is, when the output transistor is turned on and off. FIG. 2 is an overall front view of the game board 21.

  In the gaming machine 1 configured as described above, first, a game ball is launched from the hitting ball launching device by the player's operation of the hitting operation handle 2 and passes between the hitting ball guide rail 3 and the game area forming rail 4. A ball is launched into the game area 5 on the game board 21. Then, the game ball falls in the game area 5 due to its own weight, and in the process of falling, the game ball 21 is changed in the direction of dropping by a game nail or windmill 20 (not shown) implanted in the game board 21, and the start winning device 11 or When the normal winning devices 14a and 14b are won, when the normal symbol operating gate 19 is passed, or when all the winning devices are not won, they are collected at the out port 16.

  When the game ball wins the start winning device 11, the game is detected by the count sensor 60 and given a predetermined prize ball (for example, 5) to the player, and each symbol display unit 8, 9 of the special symbol display device 6 is used. 10 to display a special symbol in a scrolling manner, and after a predetermined time, a slot game is performed in which the special symbol is stopped in order of the left symbol display unit 8, the right symbol display unit 10, and the middle symbol display unit 9, and a lottery is performed. When the special symbol of the right symbol display unit 10 stops and the special symbol combination that constitutes the big hit (for example, the special symbol of the left symbol display unit 8 and the special symbol of the right symbol display unit 10 are the same) The special symbol display device 6 displays a predetermined reach action, and after that the special symbol in the middle symbol display unit 9 is stopped and displayed. If the special symbol is a combination of special symbols determined in advance, it will be a big hit, the attacker as the big winning device 7 will be opened in a predetermined manner, and if it is a combination of special symbols other than these Will be out of place. Note that the special symbol combinations that are jackpots include those that are in a high probability state (so-called probability variation state) in which the probability of jackpot increases until the next jackpot occurs.

  Further, when the game balls win the normal winning devices 14a and 14b, the winning game balls are detected by the count sensor 60, and predetermined prize balls (for example, 15 balls) are given to the player. Further, when the game ball passes through the normal symbol operating gate 19, the normal symbol display device 18 displays the normal symbol in a variable manner, the lottery is performed, and the confirmed normal symbol is a predetermined normal symbol. The winning winning device (electric tulip) 11 is opened for a predetermined time. With the gaming machine 1 configured as described above, a player can enjoy a pachinko game.

  By the way, among players, a pachinko ball that falls on the game board 21 using a magnet is guided to a desired winning device, for example, a normal winning device 14a, 14b having a large number of winning balls, and is awarded from a winning opening. There are malicious players who get prize balls illegally. In particular, recently, a pachinko ball slightly larger than the regular size, which is commonly referred to as a deca ball (about 0.4 mm larger than the regular size) is used, and the deca ball is launched into the game area 5 on the game board 21 to obtain a game area 5 The big balls that have been struck are guided to the winning gates of the normal winning devices 14a and 14b by magnets, and are awarded to the count sensor 60. Thereafter, the big winning devices 14a and 14b in which the big balls are stopped during a big hit game or the like. Irradiating an electromagnetic wave toward (count sensor 60) frequently causes an improper act of causing a malfunction in which the output transistor of the count sensor 60 is repeatedly turned on and off to obtain a large number of pachinko balls.

  Therefore, in the gaming machine 1 according to the present invention, the normal winning device 14a, 14b and the starting winning device 11 using the magnets are provided with an anti-tamper device 30 for preventing an illegal act of winning a pachinko ball. 14b and the start winning device 11, and the fraud prevention device 30 will be described in detail below.

  First, the configuration of the fraud prevention device 30 will be described with reference to FIGS. 3 to 6. FIG. 3 is an overall perspective view of the anti-fraud device 30 as viewed from obliquely above and to the right. FIG. 4 shows the right side of the anti-fraud device 30 showing a state where the upper portion of the housing 41 and the side plate 46 on the front (right side) are deleted. FIG. 5 is a perspective view seen obliquely from above, FIG. 5 is a right side cross-sectional view of the fraud prevention device 30 showing a state in which the side plate 46 in front of the housing 41 is deleted, and FIG. It is a plane sectional view of fraud prevention device 30 which shows the state where 47 was deleted.

  As shown in FIGS. 3 to 6, the anti-tamper device 30 is roughly composed of a stopper piece 40 and a housing 41. The stopper piece 40 is formed of a magnetic material such as a metal attracted by the magnetic force of the magnet, and a malicious player uses a magnet to drop a pachinko ball that falls on the game board 21 with a winning device (ordinary winning device 14a, 14b, when an illegal act for winning the start winning device 11) is performed, the magnetic force of the magnet projects above the winning opening (winning path) of the winning device (ordinary winning devices 14a, 14b, start winning device 11), and the pachinko It is a member that prevents the ball from winning the prize device.

  The stopper piece 40 includes a horizontal flat plate-like protruding portion 40a that appears and disappears at the top of the winning opening serving as a winning path and prevents the pachinko ball from winning, and a vertical flat plate-like movement restricting portion 40b that restricts the movement of the protruding portion 40a. The rear end portion of the projecting portion 40a is connected to the central portion of the movement restricting portion 40b and is integrally formed in a substantially T shape (see FIG. 4). Further, arc-shaped locking portions 50, 50 are formed on the upper and lower ends of the movement restricting portion 40b, and the locking portions 50, 50 are protrusions 52 of the casing 41 described later. , 52 to restrict the movement of the protrusion 40a.

  The casing 41 is formed of a front plate 45 made of a synthetic resin such as plastic, left and right side plates 46, 46, a ceiling plate 47, a bottom plate 48, and a rear plate 49 in a hollow, substantially rectangular parallelepiped shape. An insertion hole 44 having the same shape (slightly larger than the protruding portion 40a) as the protruding portion 40a for inserting the protruding portion 40a of the stopper piece 40 is formed in the center portion of the front plate 45. At the center of the upper and lower ends, attachment portions 42 and 42 for attaching the fraud prevention device 30 to the game board 21 are provided.

  Further, on the inner side of the housing 41, the central portion of the connection portion between the upper end of the front plate 45 and the front end of the ceiling plate 47 and the central portion of the connection portion between the lower end of the front plate 45 and the front end of the bottom plate 48 are each formed of a metal piece or the like. Contact members 53, 53 are provided (see FIGS. 5 and 6), and the contact members 53, 53 are arranged such that when the protruding portion 40a of the stopper piece 40 protrudes above the winning opening, The improper alarm lamp 31 is lit / flashed by contacting the movement restricting portion 40b and conducting. In the figure, reference numeral 43 denotes an electric wire. The electric wire 43 is connected to the contact members 53 and 53 and the fraud alarm lamp 31 in order to electrically connect the contact members 53 and 53 and the fraud alarm lamp 31. It has become.

  Also, substantially hemispherical protrusions 52 and 52 are provided on the inner side of the casing 41 and slightly closer to the rear plate 49 side than the center of the ceiling plate 47 and the bottom plate 48, respectively. 52 is formed of an elastic member such as rubber, and normally engages with the movement restricting portion 40b of the stopper piece 40 to fix the protruding portion 40a of the stopper piece 40 so that it does not move, while a fraudulent act with a magnet was performed. Sometimes, that is, when a magnetic force is applied to the stopper piece 40 by a magnet, the protruding portion 40a of the stopper piece 40 is allowed to protrude above the winning opening due to elastic deformation.

  In the fraud prevention device 30 including the stopper piece 40 and the casing 41, the protrusion 40 a of the stopper piece 40 is inserted into the insertion hole 44 of the casing 41 and the movement restricting portion 40 b of the stopper piece 40 is locked. In a state where the portions 50 and 50 are engaged with the protrusions 52 and 52 of the housing 41, the movement restricting portion 40b of the stopper piece 40 and the central portion of the rear plate 49 of the housing 41 are connected to each other by a spring 51. The piece 40 is configured to be biased so as to protrude to the upper part of the winning opening (ordinary winning devices 14a and 14b, the starting winning device 11). Accordingly, the fraud prevention device 30 configured in this manner reliably projects the stopper piece 40 above the winning opening serving as the winning path, even if the magnet used for fraud is weak. It becomes possible to prevent cheating.

  Next, the operation of the fraud prevention device 30 will be described with reference to FIGS. FIG. 7 is a partial cross-sectional view of the gaming machine 1 showing a state in which the anti-fraud device 30 is attached to the game board 21, and FIG. 8 shows pachinko balls P 1 and fraud prevention when an illegal act is performed by the magnet 70. FIG. 9 is a partial cross-sectional view of the gaming machine 1 showing the state of the device 30, and FIG. 9 is a circuit diagram showing the relationship between the stopper piece 40 and the fraud alarm lamp 31, and FIG. It is a circuit diagram which shows the normal state which is not performed, (B) is a circuit diagram which shows a state when the fraudulent act by the magnet 70 is performed.

  The fraud prevention device 30 is screwed on the back surface of the game board 21 via attachment parts 42 and 42 of the housing 41 so that the protrusion 40a of the stopper piece 40 can protrude forward of the game board 21 above the normal winning device 14a. 57 and 57 are screwed together. Thus, as shown in FIGS. 7 and 8, the game board 21 has a through hole 54 having the same shape as the protrusion 40a (slightly larger than the protrusion 40a) in advance so that the protrusion 40a of the stopper piece 40 can pass therethrough. The game board 21 is drilled from the front surface to the back surface.

  In this embodiment, the fraud prevention device 30 is provided corresponding to the normal winning device 14a, but it may be provided corresponding to the normal winning device 14b or the start winning device 11. . In the figure, 61 is a winning ball passage, and a game ball won in the normal winning device 14a is detected by flowing down the winning ball passage 61 and passing through the count sensor 60. A predetermined number of prize balls is paid out for the detection of the count sensor 60. In the figure, reference numeral 27 denotes a glass plate, and this glass plate 27 is formed with a predetermined interval from the game board 21 (the interval between the inner glass plate 27 and the game board 21 is about 20 mm).

  Now, with respect to the gaming machine 1 to which the anti-fraud device 30 is attached in this way, a malicious act of causing a malicious player to win the normal winning device 14a with the pachinko ball P1 falling on the game board 21 using the magnet 70. The operation of the fraud prevention device 30 when it works will be described with reference to FIG. The malicious player brings the magnet 70 through the glass plate 27 close to the pachinko ball P1 falling on the game board 21, and guides the pachinko ball P1 to the targeted normal winning device 14a. When the pachinko ball P1 approaches the winning opening of the normal winning device 14a, the stopper piece 40 (projecting portion 40a) formed of the magnetic material of the fraud preventing device 30 is attracted to the magnet 70 by the magnetic force of the magnet 70. Projecting forward from the game board 21.

  That is, when the pachinko ball P1 approaches the winning opening of the normal winning device 14a by the magnet 70, the movement restricting portion 40b of the stopper piece 40 is an elastic member of the housing 41 by the magnetic force of the magnet 70 and the biasing force of the spring 51. The formed protrusions 52 and 52 are pressed and elastically deformed to release the engagement state between the locking parts 50 and 50 of the movement restricting part 40b and the protrusions 52 and 52. As a result, the protrusion 40a of the stopper piece 40 is released. Protrudes forward of the game board 21 so as to substantially cover the winning opening of the normal winning device 14a, and the pachinko ball P1 is prevented from winning the normal winning device 14a as shown in FIG.

  That is, a malicious player tries to obtain a prize ball by passing the pachinko ball P1 through the count sensor 60 of the normal winning device 14a by an illegal act using the magnet 70. The device 30 prevents the pachinko ball P1 from reaching the count sensor 60 by causing the stopper piece 40 to project by the magnetic force of the magnet 70 on the winning path of the normal winning device 14a upstream of the count sensor 60. In this way, it is possible to prevent in advance the payout of an erroneous prize ball due to such an illegal act.

  When the stopper piece 40 protrudes forward from the game board 21, the movement restricting portion 40 b of the stopper piece 40 comes into contact with the contact members 53, 53 of the housing 41 and is energized. As a result, the fraud alarm lamp 31 is turned on / off. Flashes and informs the outside that an illegal act by the magnet 70 has been performed. That is, as shown in FIG. 9, the movement restricting portion 40 b of the stopper piece 40 serves as a switch, and the movement restricting portion 40 b and the contact members 53, 53 are in a normal state in which an illegal act by the magnet 70 is not performed. In a non-contact state, the circuit is open and not energized, and as a result, the fraud alarm lamp 31 is turned off. On the other hand, in the state where the illegal act by the magnet 70 is being performed, the movement restricting portion 40b and the contact members 53 and 53 are in contact with each other and the circuit is closed and energized. As a result, the fraud alarm lamp 31 is lit / flashed.

  Accordingly, when the fraud alarm lamp 31 of the gaming machine 1 is turned on / flashing, the hall staff who discovers this can quickly rush to the gaming machine 1 where the fraudulent act has been performed, thereby identifying the malicious player. It is also possible to prevent such illegal acts. Moreover, in the gaming machine 1 in which the illegal act is performed, the stopper piece 40 of the anti-fraud device 30 protrudes from the game board 21, so this state also serves as evidence that the illegal act has been performed.

  In this embodiment, the fraudulent act by the magnet 70 is notified to the outside by the fraud alarm lamp 31 provided in the gaming machine 1, but this is not limited, and equipment other than the gaming machine 1, for example, You may make it provide the fraud alarm lamp 31 in the island stand side which installs the gaming machine 1. Alternatively, when the fraud alarm lamp 31 is activated, a call lamp or a representative lamp (top lamp) provided on the island stand may be lit / flashed in a predetermined manner. ) May be sent to a hall management computer or hall staff income. In this way, it is possible to further increase the ability to prevent and deter fraud.

  Then, when the measures against the malicious player who has committed the cheating are completed, the hall staff or the like presses the stopper piece 40 of the anti-fraud device 30 protruding from the game board 21 to the rear side of the game board 21 by hand. Thus, the stopper piece 40 before the original fraud can be performed can be returned to the state where it does not protrude from the game board 21. That is, the movement restricting portion 40b of the stopper piece 40 is pressed against the urging force of the spring 51 to elastically deform the protruding portions 52, 52 of the housing 41, and the locking portions 50, 50 of the movement restricting portion 40b are protruded. By engaging with 52, 52, it is possible to return the gaming machine 1 to a normal state in which a game can be played very easily.

  As is apparent from the above description, the fraud prevention device 30 in the gaming machine 1 of the present embodiment guides a pachinko ball falling on the game board 21 to a winning opening of a desired winning device by using a magnet to obtain a prize ball. It is possible to prevent damage caused by such an illegal act in advance by preventing the pachinko ball from winning the winning device with a very simple configuration without using a magnetic sensor. As a result, it is possible to prevent illegal acts of acquiring a large amount of pachinko balls by clogging the popular deca balls that have been frequently occurring recently with the count sensor 60 of the winning device and then irradiating electromagnetic waves during a big hit game or the like. Therefore, it is not necessary to provide an electromagnetic wave sensor. In other words, the anti-fraud device 30 in the gaming machine 1 of the present embodiment is very inexpensive and does not use a magnetic sensor or an electromagnetic wave sensor to guide the pachinko ball to the winning opening of the winning device by using a magnet and obtain a prize ball. There is an excellent effect that it can be surely prevented with a simple configuration.

  Furthermore, a fraud alarm lamp 31 is provided to notify that fraud has been performed when the fraud prevention device 30 is activated, and this fraud alarm lamp 31 serves as a switch for the fraud prevention device 30. Since the stopper piece 40 (movement restricting portion 40b) comes into contact with the contact members 53 and 53 of the housing 41 and is energized, that is, the stopper piece 40 also serves as a switch for the fraud alarm lamp 31. As a result, the circuit configuration of the anti-fraud device 30 can be simplified, and troublesome work such as installation of a device for lighting a lamp or the like and routing of wiring for notifying that an illegal act has been performed can be easily performed. can do.

  Furthermore, the anti-fraud device 30 can be attached to the gaming machine 1 with a simple unit structure, and can be attached to the gaming machine 1 by an extremely simple operation that is screwed to the back surface of the gaming board 21 with screws 57, 57, for example, discarded games. It can be easily removed from the machine 1 and recycled to other gaming machines 1, thereby reducing the cost.

  The fraud prevention device 30 in the gaming machine 1 according to the embodiment of the present invention has been described based on the drawings, but the specific configuration is not limited to that shown in the embodiment, and the gist of the present invention. Any changes or additions that do not deviate from the above are included in the present invention.

  For example, in this embodiment, the fraud prevention device 30 is provided so as to correspond to the winning opening of the winning device, but this may be provided so as to correspond to the passing port of the passing device (normal symbol operation gate 19). Since the winning device and the passing device are common in terms of generating profits for the player, even if the fraud prevention device 30 is provided so as to correspond to the passing port of the passing device, it is the same as when the winning device is provided. There is an effect.

  Next, another embodiment of the fraud prevention device 30 will be described with reference to the drawings. First, another embodiment 1 will be described with reference to FIGS. 10 to 13. FIG. 10 is an overall perspective view of the anti-fraud device 80 as viewed from the upper right side, and FIG. 11 is an overall view of the anti-fraud device 80 as viewed from the upper right side of the state in which the stopper piece 84 (projection 84a) protrudes. FIG. 12 is a partial cross-sectional view of the gaming machine 1 showing a state in which the anti-tamper device 80 is attached to the game board 21, and FIG. 13 shows a pachinko machine when an illegal act is performed by the magnet 70. 2 is a partial cross-sectional view of the gaming machine 1 showing a state of a ball P1 and an anti-fraud device 80. FIG. In addition, in this other Embodiment 1, the same code | symbol is attached | subjected about the structure similar to embodiment mentioned above, and description about these structures is abbreviate | omitted.

  In other embodiment 1, the point which is greatly different from the above-described embodiment is simply that the fraud prevention device 80 is connected to the game board so that the fraud prevention device operates reliably even when the magnetic force of the magnet is weak. 21 is a point that is attached from the front side of 21 and a point that is a stopper piece 84 having a larger shape at the tip of the stopper piece.

  As shown in the figure, in the fraud prevention device 80 according to the other embodiment 1, the stopper piece 84 is formed in a horizontal flat plate-like projecting portion 84a that appears and disappears at the top of the winning opening and prevents the pachinko ball from winning. Even if the magnetic force of the magnet is weak, the tip of the protrusion 84a is provided with a vertical flat plate-like tip 84c for attracting the stopper piece 84 to the magnet, and the protrusion 84a and the tip 84c Are integrally formed in a substantially T-shape. And the protrusion part 84a is formed shorter than the protrusion part 40a of above-mentioned embodiment, when the fraud prevention apparatus 80 is attached from the front side of the game board 21. FIG. That is, the movement restricting portion 40b of the stopper piece 84 is arranged closer to the front side of the game board 21 than the movement restricting portion 40b of the stopper piece 40 of the above-described embodiment.

  Also, the upper and lower portions of the front plate 45 of the housing 41 (see FIG. 11) have substantially the same shape as the tip 84c and are larger than the mounting portions 42, 42 of the above-described embodiment. The fraud prevention device 80 is attached from the front side of the game board 21 through the attachment portions 82 and 82 (see FIG. 12). And between the attachment parts 82 and 82, the front-end | tip part 84c of the stopper piece 84 fits perfectly, and contacts the surface of the front board 45, Therefore, the front-end | tip part 84c is between the attachment parts 82 and 82. In the state in which is fitted, the surface formed by the attachment portions 82 and 82 and the tip end portion 84c is a flat surface having no irregularities.

  As described above, the mounting portions 82 and 82 and the tip end portion 84c located on the surface of the game board 21 are formed on a flat surface, so that they are attached from the front side of the game board 21 and located immediately above the normal winning device 14a. The fraud prevention device 80 does not affect the pachinko ball P1. In other words, the fraud prevention device 80 does not affect the winning of the pachinko ball P1 to the normal winning device 14a in a normal state where no fraudulent action is performed by the magnet. .

  Then, in the gaming machine 1 to which the anti-fraud device 80 is attached, as shown in FIG. 13, a malicious player brings the magnet 70 through the glass plate 27 close to the pachinko ball P1 falling on the game board 21, and aims When the pachinko ball P1 is guided to the winning opening of the attached normal winning device 14a, the stopper pieces 84 (protruding portions 84a and tip portions 84c) formed of the magnetic material of the fraud preventing device 80 by the magnetic force of the magnet 70 are magnetized. It is sucked by 70 and protrudes forward from the game board 21.

  That is, when the pachinko ball P1 approaches the winning opening of the normal winning device 14a by the magnet 70, the stopper piece 84 (protruding portion 84a, tip portion 84c) of the game board 21 so as to substantially cover the winning opening of the normal winning device 14a. Projecting forward, the pachinko ball P1 is prevented from winning the normal winning device 14a as shown in FIG. That is, the payout of the wrong prize ball due to the illegal act by the magnet 70 is prevented in advance.

  Since the anti-fraud device 80 is attached from the front side of the game board 21, when the anti-fraud device 80 is attached from the front side of the game board 21 in this way, the magnet 70 and the movement restricting portion 40b of the stopper piece 84 are not connected. This is a case where the magnetic force of the magnet 70 is weaker than the fraud prevention device 40 of the above-described embodiment, coupled with the fact that the distance is shortened and the stopper piece 84 is provided with the tip 84c. Also, the stopper piece 84 is surely attracted to the magnet.

  In the other embodiment 1, since the anti-fraud device 80 is attached from the front side of the game board 21, the game board 21 is previously connected to the casing 41 of the anti-fraud device 80 as shown in FIGS. A fitting hole 55 having the same shape (slightly larger than the housing 41) is formed from the front surface of the game board 21 toward the back surface. In the other embodiment 1, the fitting hole 55 is formed by drilling a part of the thickness of the game board 21 from the front side of the game board 21 according to the size of the casing 41 as shown in the drawing. However, it may be formed so as to penetrate from the front surface to the back surface of the game board 21, that is, larger than the housing 41.

  Next, another modification of the first embodiment will be described with reference to FIGS. 14 and 15. 14 is a front view of the normal winning device 14a to which the fraud prevention device 80 is attached, and FIG. 15 is a partial cross-sectional view of the gaming machine 1 showing a state in which the fraud prevention device 80 is attached to the game board 21. . In addition, in the modification of this other Embodiment 1, the same code | symbol is attached | subjected about the structure similar to Embodiment mentioned above and the other Embodiment 1, and description about these structures is abbreviate | omitted.

  In this other variation of the first embodiment, the point that differs greatly from the above-described embodiment and the other embodiments 1 is that, in short, the fraud prevention device 80 can be easily attached to the game board 21 so that it can be easily installed. The prevention device 80 and the regular winning device 14a are integrally formed.

  In the other variation of the first embodiment, the normal winning device 14a includes a pedestal 87 extending above the normal so that the fraud preventing device 80 can be integrally formed on the upper portion of the winning opening. As shown in FIG. 15, the fraud prevention device 80 is attached to the back side of the portion extending above the pedestal 87.

  The fraud prevention device 80 is attached so that the front surface 45 of the front plate 45 of the housing 41 is in contact with the back surface of the pedestal 87, and the tip end portion 84 c of the stopper piece 84 is formed in the same size as the thickness of the pedestal 87. Then, it is fitted in a fitting hole 88 formed in the base 87. That is, the front end portion 84c of the stopper piece 80 is fitted into the fitting hole 88 so as to come into contact with the surface of the front plate 45. As a result, the front end portion 84c is fitted into the fitting hole 88. In the present state, the surface formed by the pedestal 87 and the tip end portion 84c is a flat surface without irregularities. Therefore, as in the case of the other embodiment 1, the anti-fraud device 80 does not affect the winning of the pachinko ball to the normal winning device 14a in a normal state where no illegal act by the magnet is performed.

  In the modification of the other embodiment 1 configured as described above, the fraud prevention device 80 is also attached to the game board 21 at the same time only by attaching the normal winning device 14a to the game board 21. The troublesome work of attaching only 80 to the game board 21 separately from the normal winning device 14a can be eliminated. That is, when the fraud prevention device 80 is attached to the game board 21, it must be attached to the game board 21 while maintaining an accurate positional relationship with the normal winning device 14a. In this regard, the normal prize winning device 14a and the fraud prevention device 80 In the other modified example of the first embodiment, the troublesome mounting work of the fraud prevention device 80 to the game board 21 can be eliminated.

  Next, another embodiment 2 will be described with reference to FIGS. 16 is a front view of the normal winning device 14a to which the fraud prevention device 90 is attached, and FIG. 17 is a partial sectional view of the gaming machine 1 showing a state in which the fraud prevention device 90 is attached to the game board 21. 18 is a partial cross-sectional view of the gaming machine 1 showing the state of the pachinko ball P1 and the anti-fraud device 90 when an illegal act by the magnet 70 is performed, and FIG. 19 is a stopper piece 97 of the anti-fraud device 90. (A) is a side view of the stopper piece 97 showing a normal state in which the cheating by the magnet 70 is not performed, and (B) is a cheating by the magnet 70. It is a side view of the stopper piece 97 which shows the state at the time.

  In the other embodiment 2, the point that is greatly different from the above-described embodiment, the other embodiment 1 and the modification of the other embodiment 1 is that the fraud prevention device 90 is made compact by using a link mechanism. The point which formed and the point which made it possible to arrange | position the fraud prevention apparatus 90 near the glass plate 27 so that even if the magnetic force of a magnet is weak, a fraud prevention apparatus operates reliably. In addition, in this other embodiment 2, the same code | symbol is attached | subjected about the structure similar to the embodiment mentioned above, the other embodiment 1, and the modification of other embodiment 1, and description about these structures is abbreviate | omitted.

  In the other embodiment 2, the normal winning device 14a has a thick front plate 95 so that the fraud prevention device 90 can be accommodated in the front plate 95. The front plate 95 is formed with a hollow portion 94 whose rear side is open, and the tamper-proof device 90 is configured to be compact by accommodating a stopper piece 97 of the link mechanism in the hollow portion 94 ( (Refer FIG. 17, FIG. 18).
