Description

  The present invention relates to a technique for preventing fraudulent acts on a game machine represented by a slot machine.

  In the slot machine, a plurality of reels with a plurality of patterns are rotated by the player's start operation on the start lever, and the rotation of the corresponding reel is stopped by the player's stop operation on the stop button corresponding to each reel. Then, the winning combination corresponding to the case where the combination of the patterns displayed by the reels at the time of the stop is a predetermined combination will be won. Although the stop of the reel depends on the timing of the player's stop operation, it does not completely correspond to the timing of the stop operation, and certain control is applied according to the prize winning lottery result performed in advance. In other words, on the assumption that a winning combination lottery will be won in advance, if the player performs a stop operation at an appropriate timing, the winning combination can be won.

  The lottery for winning combination is performed according to the count value of a counter that counts a number cyclically with a certain period, triggered by the player's start operation on the start lever. In this lottery principle, the same lottery result is obtained if the start operation is performed at the same cycle as the counter cycle. Therefore, cheating using instruments that focus on the lottery principle is rampant. This device operates at a multiple of the counter cycle and applies an external force to the start lever. Once the timing for winning a winning combination such as a bonus is found, the start operation is performed with this device every time. Wins a winning role such as a bonus.

  Therefore, Patent Document 1 proposes an instrument for preventing such illegal acts. In Patent Document 1, the start lever is covered with a soft material to prevent the start lever from being moved by an external force from an unauthorized device.

JP 2004-298551 A

However, the instrument of Patent Document 1 cannot prevent an illegal act by an instrument that generates a larger external force. In addition, a larger force is required for the start operation on the start lever, which deteriorates the operability of the start lever. ,
Accordingly, an object of the present invention is to prevent a fraudulent act without requiring a greater force for the start operation on the start lever.

  According to the present invention, in a gaming table for performing lottery with a player's start operation on the start lever, a cover member provided around the operation portion of the start lever, and the operation portion via the cover member There is provided a gaming machine comprising: fluctuating means for fluctuating the action timing of the starting operation to act.

  Further, according to the present invention, in the dishonest act device provided in the gaming table for performing the lottery in response to the start operation of the player with respect to the start lever, the cover member provided around the operation portion of the start lever, There is provided a fraud prevention instrument characterized by comprising: fluctuating means for fluctuating the action timing of the start operation that acts on the operation part via a cover member.

  In the present invention, since the changing means is provided, even if the start operation is performed at a constant cycle by an unauthorized instrument or the like, the operation timing of the start operation that acts on the operation unit varies. As a result, the start operation detected by the game machine does not have a fixed period, and illegal acts can be prevented. In addition, since the principle of preventing fraud is to change the action timing, the starting operation does not require a greater force than before. Note that the lottery performed in response to the start operation in the present invention includes, for example, a lottery for a right that affects a player's profit, such as a lottery for a winning combination.

  As described above, according to the present invention, the starting operation with respect to the start lever does not require a greater force, and the illegal act can be prevented.

<Basic control of games>
FIG. 5 is a flowchart showing basic control of the game in the slot machine 100. Basic control of the game is performed mainly by the Main CPU 310, and the game process shown in FIG. Hereinafter, this game process will be described. When the power is turned on, first, initial processing for initializing the main control unit 300 is executed in S101. In S102, game start processing is performed. Here, processing related to medal insertion, detection processing of a start operation for the start lever 135, and the like are performed.

  In S103, the random number generated by the random number generation circuit 317 is acquired. In S104, an internal lottery of a winning combination is performed using the random number acquired in S103 and the winning combination lottery table stored in the ROM 312. As a result of the internal lottery, when any winning combination is won internally, the winning combination flag set in the RAM 313 is turned ON. Examples of winning combinations include replay (replay), small combination, bonus (BB, RB), and the like.

  Each winning combination has a winning probability of internal lottery set for each bet number of medals and set values (1 to 6), and the winning combination lottery table is configured in accordance with this and is obtained at the time of the lottery. The numerical value range (for example, 0 to 16384) is divided in advance into several areas (areas corresponding to the size of each winning probability), and each area is associated with winning or losing of each winning combination. . In the internal lottery of the winning combination, whether or not the internal winning of the winning combination is successful is determined according to which range the acquired random number value belongs. This method is also adopted in other lottery processes.

  In S104, the reel stop control table is selected after the internal lottery. This is a process of selecting a control for the stop operation of each reel. Here, the stop control of the reels 110 to 112 will be briefly described. The reel stop control is performed based on the selected reel stop control table by selecting one of a plurality of predetermined reel stop control tables based on the internal lottery result.

  The reel stop control table is stored in the ROM 312 of the main control unit 300. The reel stop control table is allowed to display the corresponding combination of symbols for the winning combination won internally by the internal lottery or the so-called flag carryover winning combination. It is configured so that the pattern combinations corresponding to each winning combination are not displayed together. For example, if the “bell” of the small role is not internally won, even if the reels 110 to 112 are stopped at the timing when the “bell” symbol combination is displayed, the reels 110 to 112 are stopped immediately. Therefore, control is performed so that the combination of bell patterns is not completed. On the other hand, when “Bell” is won internally, even if the reels 110 to 112 are not stopped at the timing when the bell picture combination is displayed, the reels 110 to 112 are within a certain range. It will be controlled so that the combination of the pattern of the bells is aligned without stopping immediately.

In S105, rotation of all reels 110 to 112 is started. Thereafter, the stop buttons 137 to 139 can be received. In S106, reel stop control is performed. Here, in response to an operation on the stop buttons 137 to 139, one of the reels 110 to 112 corresponding to the operated stop button 137 to 139 is stopped according to the reel stop control table selected in S104. When all the reels 110 to 112 are stopped, the process proceeds to S107.
Stop according to the table.

  In S107, a winning determination is performed. Here, it is determined that a winning combination has been won when a picture combination corresponding to an internally winning winning combination or a winning combination with a flag carryover is displayed on the activated winning line 114. For example, if “bell-bell-bell” is arranged on the validated winning line 114, it is determined that the bell is won. In addition, the flag corresponding to the winning combination won is reset. In S108, if any winning combination with payout is won, the number of medals corresponding to the winning combination is paid out. In S109, game state control processing is executed. In this gaming state control process, control for changing the gaming state is performed. For example, in the case of a bonus winning such as a big bonus or a regular bonus, a corresponding bonus game is prepared so that it can be started from the next time. In the game, prepare to start the normal game next time. As described above, the process of one game is completed, and then the process returns to S102 and the same process is repeated to advance the game.

<First Embodiment>
Next, prevention of fraud against the start lever 135 will be described. 6A is a perspective view showing a mode in which the cheating device A according to the first embodiment of the present invention is attached to the start lever 135, FIG. 6B is a cross-sectional view of the cheating device A, FIG. (C) is a front view of the fraud prevention instrument A. FIG.

  The cheating prevention instrument A includes a cover member 10 provided around the operation portion 135a of the start lever 135, and a plurality of protrusions 11 that vary the operation timing of the start operation that acts on the operation portion 135a via the cover member 10. And comprising. In the case of this embodiment, the cover member 10 is formed from a resin having flexibility and has a cup shape. The cover member 10 has a hole through which the shaft portion 135b of the start lever 135 passes, and is attached to the shaft portion 135b so as to be rotatable around the axis of the start lever 135 when the shaft portion 135b is inserted by loose fitting. . In the case of the present embodiment, not only the operation unit 135 a but also the entire portion of the start lever 135 that protrudes from the front door 102 is covered with the cover member 10.

  In the case of the present embodiment, the protruding portion 11 is provided integrally with the cover member 10, protrudes from the inner surface of the cover member 10 toward the operation portion 135a, and extends around the operation portion 135a in a direction parallel to the radial direction of the shaft portion 135b. It is extended. As shown in FIG. 6C, the plurality of protrusions 11 include those having different protrusion lengths, and the end surfaces of the protrusions 11 are orthogonal to the extending direction of the protrusions 11. It is formed inclined from the surface.

  Next, the operation of the fraud prevention instrument A will be described. In the case of this embodiment, since the operation part 135a of the start lever 135 is surrounded by the cover member 10, the start operation with respect to the start lever 135 needs to be performed via the cover member 10. That is, when an external force is applied to the cover member 10, this is transmitted to the operation unit 135a, and the start lever 135 rotates to detect the start operation.

  Here, when an external force is applied to the cover member 10, the start lever 135 of the cover member 10 is deformed by the deformation of the flexible cover member 10 or the cover member 10 being supported by the shaft portion 135b by loose fitting. As a result of the relative displacement, the protruding portion 11 abuts on the operation portion 135a, and an external force acts on the operation portion 135a. As a result, the start lever 135 rotates. At this time, since the protrusions 11 include ones with different protrusion lengths, it is assumed that the start operation is performed on the cover member 10 at the same cycle by the protrusions 11 contacting the operation part 135a. However, the action timing of the start operation acting on the operation unit 135a varies.

  As a result, even if an attempt is made to perform a start operation using the above-described cheating device, the start operation is not detected at the same cycle each time, and cheating is prevented. Further, since the cover member 10 can rotate around the axis of the start lever 135, even if the start operation is performed by applying an external force from the same direction, a different protruding portion 11 is applied to the operation portion 135a each time the cover member 10 rotates. The action timing of the start operation can be changed. In particular, in this embodiment, since the end surface of the protruding portion 11 is inclined, when the protruding portion 11 contacts the operation portion 135a, the rotation force can be applied to the cover member 10 by the inclination, and the start operation The cover member 10 can be rotated every time. The fraud prevention instrument A can be mounted by once removing the operation portion 135a of the start lever 135 from the shaft portion 135b, and can be applied to an existing slot machine as a retrofit.

Second Embodiment
FIG. 7A is a perspective view showing a mode in which the cheating device B according to the second embodiment of the present invention is attached to the start lever 135, and FIG. 7B is a cross-sectional view of the cheating device B. The fraud prevention instrument B includes a cover member 20 and a viscous liquid 21 enclosed in the cover member 20.

  The cover member 20 is configured to form an enclosure space that surrounds the operation portion 135a, and seals the cup-shaped cup portion 20a made of a resin having flexibility and the like, and the opening end of the cup portion 20a and the shaft. And an attachment plate 20b attached to the portion 135b. In the case of the present embodiment, not only the operation unit 135 a but also the entire part of the start lever 135 that protrudes from the front door 102 is surrounded by the cover member 20.

  The cup portion 20a and the mounting plate 20b are fixed in a liquid-tight manner. Further, the mounting plate 20b has a hole through which the shaft portion 135b is inserted, and the shaft portion 135b is liquid-tightly fitted into this hole. Thereby, the inside of the cover member 20 forms a liquid-tight enclosure space. The viscous liquid 21 is, for example, oil or jelly-like liquid, and is filled so as to be able to flow in the cover member 20.

  Next, the operation of the fraud prevention instrument B will be described. In the case of this embodiment, since the operation part 135a of the start lever 135 is completely enclosed by the cover member 20, the start operation with respect to the start lever 135 needs to be performed via the cover member 20, especially the cup part 20a. That is, when an external force is applied to the cover member 20, this is transmitted to the operation unit 135a, and the start lever 135 is rotated to detect the start operation.

  Here, when an external force is applied to the cup portion 20a, the flexible cup portion 20a bends and contacts the operation portion 135a, and the external force acts on the operation portion 135a. Since the viscous liquid 21 is sealed inside the cover member 20, when the cup portion 20a is bent, the viscous liquid 21 flows in the cover member 20, and a random resistance is given to the bending of the cup portion 20a. In particular, as shown in FIG. 7B, when bubbles 21 a are mixed in the viscous liquid 21, the distribution of the bubbles 21 a accompanying the flow of the viscous liquid 21 changes, so that random resistance is further prevented from bending of the cup portion 20 a. give. Therefore, even if the start operation is performed on the cup unit 20 at the same cycle, the operation timing of the start operation that acts on the operation unit 135a varies. As a result, even if an attempt is made to perform a start operation using the above-described cheating device, the start operation is not detected at the same cycle each time, and cheating is prevented.

  In addition, the anti-tamper tool B temporarily removes the operation portion 135a of the start lever 135 from the shaft portion 135b, attaches the mounting plate 20b, and then attaches the operation portion 135a to the shaft portion 135b, to the mounting plate 20b of the cup portion 20a. It can be installed by fixing and sealing with viscous liquid, and can be applied later to existing slot machines.

  Moreover, in this embodiment, although the viscous liquid was enclosed in the cover member 20, the same effect can be acquired even if many strips are enclosed. FIG. 7C is a view showing an example in which a large number of strips 22 such as pulp are enclosed in the cover member 20. When the cup portion 20a bends, the strips 22 move within the cover member 20 and the distribution within the cover member 20 varies, giving a random resistance to the bending of the cup portion 20a.

<Third Embodiment>
FIG. 8A is a perspective view showing a mode in which the cheating device C according to the third embodiment of the present invention is attached to the start lever 135, FIG. 8B is a cross-sectional view of the cheating device C, FIG. (C) is a front view (perspective view) of the fraud prevention instrument C. FIG. The cheating apparatus C includes a cover member 30 and a ring-shaped member 31 attached to the operation unit 135a so as to be rotatable around the operation unit 135a.

  The cover member 30 includes a cup-shaped cup portion 30a configured to form an enclosure space that surrounds the operation portion 135a, and an attachment portion 30b that blocks the opening end of the cup portion 30a and is attached to the shaft portion 135b. And. In the case of the present embodiment, not only the operation unit 135 a but also the entire portion of the start lever 135 that protrudes from the front door 102 is surrounded by the cover member 30. The attachment portion 30b has a hole through which the shaft portion 135b is inserted, and is attached to the shaft portion 135b by inserting the shaft portion 135b through loose fitting.

  The ring-shaped member 31 is formed in a ring shape by fitting two U-shaped members. The cross-section of the ring-shaped member 31 has an arc shape corresponding to the outer shape of the spherical operation portion 135 a, so that the ring-shaped member 31 is attached to the operation portion 135 a so as not to drop off, and is rotatable about the axis of the start lever 135. The ring-shaped member 31 has a portion having a different thickness. In the present embodiment, a plurality of protrusions 31a are provided so that the thickness is different from a portion where the protrusion is not provided. The protruding portion 31a protrudes in a direction parallel to the radial direction of the shaft portion 135b.

  Next, the operation of the fraud prevention instrument C will be described. In the case of this embodiment, since the operation part 135a of the start lever 135 is surrounded by the cover member 30, the start operation with respect to the start lever 135 needs to be performed via the cover member 30, especially the cup part 30a. That is, when an external force is applied to the cover member 30, this is transmitted to the operation unit 135a, and the start lever 135 rotates to detect the start operation.

  Here, when an external force is applied to the cover member 30, the cover member 30 is displaced relative to the start lever 135 of the cover member 30 due to being loosely fitted to the shaft portion 135b, and the cup portion 30a. The inner surface of the ring contacts the ring-shaped member 31 attached to the operation portion 135a, and external force is transmitted to the operation portion 135a. As a result, the start lever 135 rotates. At this time, since there are a portion where the protrusion 31a is provided and a portion where the protrusion 31a is not provided on the outer periphery of the ring-shaped member 31, depending on the contact portion between the inner surface of the cup portion 30a and the outer periphery of the ring-shaped member 31, Even if the start operation is performed on the cup portion 30a at the same cycle, the action timing of the start operation acting on the operation portion 135a varies.

  As a result, even if an attempt is made to perform a start operation using the above-described cheating device, the start operation is not detected at the same cycle each time, and cheating is prevented. Further, since the ring-shaped member 31 can rotate around the operation portion 135a, even if the start operation is performed by applying an external force from the same direction, the contact portion between the inner surface of the cup portion 30a and the outer periphery of the ring-shaped member 31 is different. And the action timing of the start operation can be varied.

  In addition, the fraud prevention instrument C temporarily removes the operation part 135a of the start lever 135 from the shaft part 135b, attaches the attachment part 30b, attaches the ring-shaped member 31 to the operation part 135a, and then attaches the operation part 135a to the shaft part. It can be mounted by attaching to 135b and fixing the cup portion 30a to the mounting portion 30b, and can be applied to an existing slot machine as a retrofit.

FIG. 9B shows a state when the start lever 135 is started downward. FIG. 10 is a cross-sectional view of the cheating device D along the line XX in FIG. 9A, and FIG. 11 is an exploded perspective view of the cheating device D. 12 (a) and 12 (b) are perspective views showing a state in which the second cover member 41 of the dishonest act device D is attached to the start lever 135, and FIG. 12 (a) is when the start lever 135 is neutral. FIG. 12B shows a state when the start lever 135 is started downward.

  The dishonest act device D includes a first cover member 40 and a second cover member 41 constituting a double-structured cover member. The first cover member 40 has a hollow shape with an open rear surface, and includes slide portions 40a extending in the vertical direction on both side surfaces. The first cover member 40 is supported so as to be movable in a predetermined direction (here, up and down direction) by support members 44a and 44b respectively disposed on both sides thereof. The support members 44a and 44b are erected on the base member 46, and guide grooves 40a 'and 40b' for guiding the slide portion 40a are provided in the vertical direction on the inner side surface thereof. The first cover member 40 is disposed between the support members 44a and 44b. The slide portions 40a on both sides of the first cover member 40 are supported by the support members 44a and 44b so as to be movable in the vertical direction by sliding along the guide grooves 40a ′ and 40b ′. Is done.

  The lower ends of the guide grooves 40a ′ and 40b ′ are open, and the pair of springs 45 are loaded between the lower end surface of each slide portion 40a and the upper surface of the base member 46, so that the guide grooves 40a ′ and 40b ′. Stored inside. The spring 45 functions as an elastic member that constantly biases the first cover member 40 to a predetermined position (here, the position of FIG. 9A). The base member 46 is formed by laminating a member 46 a and a member 46 b, and the bottom surface of the base member 46 comes into contact with the inclined surface below the start lever 135 of the front door 102 when the dishonest act device D is attached to the slot machine 100. The member 46a is provided with a mounting portion 46a ′ that fits into a recess of the central lamp 152 (FIG. 1) located below the start lever 135, and the dishonest act device D is stably attached to the front door 102. .

  The second cover member 41 is formed by two U-shaped members 41 a and 41 a and surrounds the operation portion 135 a of the start lever 135. In the case of the present embodiment, not only the operation unit 135 a but also the entire portion of the start lever 135 that protrudes from the front door 102 is covered with the second cover member 41. The members 41a and 41a are formed with storage compartments 41a and 41b for storing the ring-shaped member 42 on the inner surface thereof. When the members 41a and 41a are assembled to form the second cover member 41, the storage compartments 41a and 41b are front-facing. A storage space for the oval ring-shaped member 42 is formed as viewed. The ring-shaped member 42 is stored in the storage space so as to be rotatable around the operation unit 135a.

  The ring-shaped member 42 is a member that is loosely fitted to the operation portion 135a. A plurality of protrusions 42a are provided on the outer peripheral surface of the ring-shaped member 42 so that the thicknesses thereof are partially different. The protrusions 42a extend radially in the radial direction of the ring-shaped member 42 and have different protrusion lengths. A plurality of latch grooves 42 b extending in the width direction of the ring-shaped member 42 are also provided on the outer peripheral surface of the ring-shaped member 42. The latch grooves 42b can be engaged with the end portions of the latch claws 43a and 43b. The latch claws 43a and 43b are elastic pieces such as leaf springs. The latch claw 43a has an upper end supported on the inner surface of the member 41a, and the latch claw 43b has a lower end supported on the inner surface of the member 41b. The latch groove 42b and the latch claws 43a and 43b constitute a rotation urging mechanism that rotates the ring-shaped member 42 around the operation portion 135a for each start operation.

  As shown in FIGS. 12A and 12B, the second cover member 41 accommodates therein the operation portion 135a of the start lever 135 and a part of the shaft portion 135b, and further stores the ring-shaped member 42. It is assembled and stored in the first cover member 40 from the back side of the first cover member 40. The second cover member 41 moves up and down integrally with the first cover member 40.

  Next, the operation of the fraud prevention instrument D will be described. In the case of this embodiment, the variation principle of the action timing of the start operation that acts on the operation unit 135a is the same as that of the fraud prevention instrument C, but a ring-shaped member corresponding to the ring-shaped member 31 of the fraud prevention instrument C. The main difference is that 42 rotates approximately reliably for each start operation. Details will be described below.

  Since the operation part 135a of the start lever 135 is surrounded by the first cover member 40 (and the second cover member 41) by mounting the anti-tamper tool D, the start operation for the start lever 135 is performed by the first cover member. 40 need to be done. In the case of the present embodiment, the first cover member 40 moves only in the vertical direction, and the first cover member 40 is always biased to the upper position by the spring 45, that is, the start lever 135 is in the neutral position. Therefore, the start operation pushes down the first cover member 40 downward. By defining the direction of the start operation, the direction of the start operation due to fraud can also be limited.

  When the first cover member 40 is pushed down, the second cover member 41 is also pushed down together with this, and the inner surface of the second cover member 41 comes into contact with the ring-shaped member 42 loosely fitted in the operation portion 135a, and the operation portion 135a. External force is transmitted to. As a result, the start lever 135 rotates. At this time, a plurality of protrusions 42 a are provided on the outer periphery of the ring-shaped member 42, and the protrusion lengths thereof are different from each other. Therefore, depending on the protrusion 42 a that contacts the inner surface of the second cover member 41. Even if the start operation is performed on the first cover member 40 at the same cycle, the action timing of the start operation that acts on the operation unit 135a varies.

  The behavior of the second cover member 41 and the ring-shaped member 42 at this time will be described with reference to FIG. 12. When the first cover member 40 is pushed down in the state before the start operation shown in FIG. Accordingly, the second cover member 41 also moves downward relative to the start lever 135, and the upper part of the ring-shaped member 41 loosely fitted to the operation portion 135 a contacts the inner surface of the upper portion of the second cover member 41. . As a result, a downward force is applied to the operation unit 135a to rotate the start lever 135, and the start operation is detected. If the protrusion length of the protrusion 42a above the ring-shaped member 41 that is in contact with the inner surface of the upper portion of the second cover member 41 is longer, both of them come into contact with each other at an early stage. Become faster. Conversely, if the projection length is shorter, it takes time to contact the inner surface of the upper portion of the second cover member 41, so that the timing at which the start lever 135 rotates is delayed. Thus, the operation timing of the start operation that operates on the operation unit 135a varies.

  Here, when the second cover member 41 moves downward relative to the start lever 135 as shown in FIG. 12 (b), the latch claw 43a provided on the member 41a in the course of the movement becomes a ring-shaped member. 42 is engaged with the latch groove 42b on the side of 42 and biased downward, and a counterclockwise rotational force is biased to the ring-shaped member 42 in a front view. When the start operation is completed and the second cover member 41 is raised to the original position as shown in FIG. 12A, the latch claw 43b provided on the member 41b is moved to the side ( Engage with the latch groove 42b on the opposite side of the latch claw 43a and urge upward, and urge the ring-shaped member 42 counterclockwise in front view. Thus, the ring-shaped member 42 rotates around the operation portion 135a for each start operation, and the protrusion 42a that contacts the inner surface of the upper portion of the cover member 41 during the start operation is different for each start operation, so that the operation portion 135a is more reliably performed. It is possible to vary the action timing of the start operation acting on the. The fraud prevention device D can be applied to an existing slot machine as a retrofit.
