When determining that the game start signals are input continuously the plurality of times at the prescribed period, this slot machine transfers the main CPU to a game incapable state preventing the execution of the game, puts out bet tokens or credited tokens, and executes a fraud deterrent process keeping the game in incapable state even after putting them out. When using the signal input machine, this constitution executes the fraud deterrent process, and even if using the signal input machine, it takes a tremendous time and labor till winning a bonus winning combination such as BB. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a slot machine used in a game hall such as a pachinko parlor.

  Slot machines used in pachinko parlors are called pachislot machines, and medals earned through playing games can be exchanged for various prizes. In pachislot machines, switching to a bonus mode such as the BB mode or RB mode is effective in increasing the number of medals acquired, so the player should play a game with the expectation of switching to the bonus mode. Is common. In a pachislot machine, when a specified number of medals are inserted, the operation of the start lever is activated, and when the start lever is pressed, multiple types of winning combinations or loses are determined in the winning combination lottery. Rotation starts. In order to shift to the bonus mode, it is necessary to win a bonus combination such as BB or RB in the winning combination lottery and win a prize by pressing a stop button.

  However, on most pachislot machines, the probability of winning a bonus role is much lower than other winning roles so that the pachinko parlor can secure operating profits while preventing the player from scolding the joy of the player. ing. Therefore, if the winning bonus role cannot be won and the right to win is lost, the player will be forced to invest a lot until he wins the bonus role again, which is a big disadvantage. It becomes. For this reason, when winning a bonus combination, the right to win is carried over until winning, and consideration is given so that the player's disadvantage does not become significant.

  By the way, in recent years, pachinko parlors that perform illegal acts using a special device called a driving machine have become a problem. A driving machine is used by connecting to a pachislot machine. By directly inputting various signals to the control board of the pachislot machine, operations such as inserting medals, pressing a start lever, and pressing a stop button are not performed. The game can be played repeatedly at a fixed timing. Therefore, if the driving machine is used, the bonus combination can be won in a short time without the employee playing the game himself.

  In pachinko parlors that engage in fraudulent activities, first, after the end of business hours, some of the pachislot machines are selected as bonuses using a driving machine. Then, it is advertised in advance that there is a pachislot machine with the bonus combination carried over. By doing so, it is possible to increase the rate of attracting customers immediately after the start of business the next day. Further, a player who has visited such a pachinko parlor that conducts illegal sales tends to repeatedly invest in a plurality of pachislot machines to check whether or not the bonus combination is won. This was the cause of promoting fraud in pachinko parlors.

  This fraudulent sales method loses the fairness of the game between players who visit the store immediately after the start of business and those who visit the store after that, and between other pachinko stores that do not use such a sales method. But it becomes unfair. For this reason, each manufacturer is required to make an early improvement so that the above-mentioned illegal acts cannot be performed.

  For example, Patent Documents 1 and 2 have proposed countermeasures against fraud using a driving machine. Patent Document 1 describes that when a reel stop signal is input at a certain timing, it is detected that fraud by the driving machine has been performed. Patent Document 2 describes that when a game is started at a certain timing, it is detected that fraud by a driving machine has been performed.

When the player is playing normally, it is unlikely that the operation timing of the start lever and stop button will always be constant. On the other hand, when a game is played using a driving machine, various signals are input from the driving machine at a fixed timing, so that the stop timing of each reel and the game start interval are always fixed. Patent Documents 1 and 2 detect fraud using the characteristics of such a driving machine. In Patent Documents 1 and 2, a warning is issued in response to detection of fraud, thereby preventing fraud using a driving machine.
JP-A-2005-230069 JP-A-2005-270218

  However, since the fraudulent act using the driving machine is performed by an employee of the pachinko parlor, it is conceivable that if the warning is performed as in Patent Documents 1 and 2, the fraudulent act may be continued ignoring the warning. . In addition, since the game is automatically advanced with the driving machine, there may be a case where the employee is not on the spot and does not notice the warning, such as setting the driving machine and going home. As described above, the configurations of Patent Documents 1 and 2 have not been expected to suppress illegal acts using a driving machine.

  This invention is made | formed in view of the said subject, Comprising: It aims at obtaining the high deterrent effect with respect to the fraudulent act using a driving machine.

  In order to achieve the above object, the slot machine of the present invention activates a game start operation by a bet of a game medium inserted prior to the start of a game or a pre-credited game medium, and is input by a game start operation. The random number value is acquired according to the game start signal, and the random number value is used to determine one of a plurality of types of winning roles or loses by lottery to display the variation of the symbol, and then stop the symbol. A game control means having a game enable state for enabling a game for determining whether or not the winning combination is won by a combination of symbols stopped, and a game disable state for making the game unexecutable, and a plurality of game control means In addition to storing game media, payout means for paying out the stored game media and setting the game control means to the non-gameable state in response to an input of a settlement instruction A settlement process executing means for performing a settlement process for returning the game control means to the game enabled state after causing the payout means to pay out at least one of the betted game media and the credited game media. , When the game start signal is input a plurality of times continuously at a predetermined interval, when the random number value of the same or approximate value is acquired continuously a plurality of times, and a specific winning combination When at least one of the case where the random value corresponding to is acquired is confirmed, fraud determination means for determining that fraud has been performed, and when it is determined that fraud has been performed, the game control means is The game state is shifted to the inoperable state, the betted game medium and the credited game medium are paid out to the payout means, and the inoperable state is continued after the payout. Characterized in that a fraudulent suppression process execution means for performing illegal suppression process to.

  Here, the game media are, for example, medals, coins, pachinko balls, and the like. The “same or approximate value” means that the difference between the random value acquired this time and the random value acquired last time is within a predetermined range.

  It is preferable that the game control means in the game disabled state disables the game by making it impossible to bet game media. Further, at this time, the game control means does not bet the game medium when the detection signal indicating that the game medium has been input is input, and the number of game media corresponding to the detection signal is It is preferable to make the payout means pay out.

As a specific aspect of “making it impossible to bet game media”, for example, the following aspects are exemplified.
a) Hand-insertion (game medium input) is disabled (for example, a blocker of the selector is operated).
b) Even if the hand can be thrown in, the bet is not made (the game medium reaches the payout means such as the hopper, but the betting process is not performed).
c) The operation of the bet button becomes invalid and the credited game medium is not bet.
d) Although the bet button can be operated, even if the bet button is operated, the bet is only subtracted from the credit and no bet is made.

  In addition to the above, as an aspect of the game incapable state that makes the game unexecutable, for example, the game start signal is not accepted, the symbol variation display is not allowed to be stopped (the stop signal is not accepted) ) And the like. Further, the state of the game impossible state may be changed between a case where the state is shifted during the settlement process and a case where the state is shifted during the fraud prevention process.

  In the present invention, the case where the game start signal is input a plurality of times continuously at a fixed interval, the case where the random number value having the same or approximate value is obtained a plurality of times continuously, and the identification is performed a plurality of times continuously. When at least one of the case where the random number corresponding to the winning combination is acquired is confirmed, fraud is determined and fraud suppression processing is performed so as not to return to the game-ready state. In this way, when the game is executed at a fixed timing by the driving machine, fraud deterrence processing is performed, and even when the driving machine is used, it takes a lot of time and effort to win the bonus combination. Therefore, it is possible to obtain a high deterrent effect against fraud using a driving machine.

  If the game medium is not bet, the operation of the start lever is not validated, so that the game cannot be started and the game cannot be performed. Since the betting of the game medium is carried out at the beginning of the game, if the game cannot be executed by making it impossible to bet the game medium, no additional processing is required, and the game can be efficiently performed. Can be made infeasible.

  Furthermore, when the detection signal is input, if the number of game media corresponding to the detection signal is paid out to the payout means without betting the game media, it is necessary to clear the paid-out game media. This can lead to more labor for fraud employees. In addition, when a game is played with a driving machine, a detection signal is input by electrical control without actually inserting a game medium. Therefore, if the payout is performed as described above, the game is stored in the payout means. The game media will be empty sometime and a hopper empty error will appear. If a hopper empty error occurs, simply releasing it will not return to the game-ready state, and it will be necessary to replenish the payout means with game media. The deterrent effect against fraud using can be further enhanced.

  As shown in FIG. 1, the slot machine 11 includes a slot machine main body 12 and a front door 13. The slot machine main body 12 includes a storage box 12a. The storage box 12a stores various devices for executing a game, such as a reel and a control board. The front door 13 is divided into two parts in the vertical direction, and consists of an upper door 13a and a lower door 13b. The inside of the slot machine body 12 is opened and closed by an upper door 13a and a lower door 13b.

  A display window 14 is provided on the upper door 13a. In the back of the display window 14, a first reel 15a, a second reel 15b, and a third reel 15c are provided. A plurality of types of symbols are arranged on the outer peripheral surfaces of the first to third reels 15a to 15c, and three symbols per reel are displayed through the display window 14 when the reels stop. In the slot machine 11, a total of five winning effective lines 16, consisting of three laterally and two diagonally, are set. Then, when the first to third reels 15a to 15c are stopped, it is displayed whether or not the winning combination is won by the combination of the stopped symbols on the winning effective line 16.

  The winning combination includes BB as a bonus combination, a small combination in which only medals are paid out, and a replay in which the next game can be performed without inserting medals. The winning right of the BB is carried over until winning, and when the BB wins, the BB mode shifts to a BB mode in which the payout rate (the ratio of the number of medals paid out with respect to the insertion of one medal) is higher than the normal mode.

  A liquid crystal display 17 is provided on the side of the display window 14. The liquid crystal display 17 displays, for example, various effect screens corresponding to each game mode and various messages for notifying the player and the store clerk.

  The lower door 13b has a medal slot 19 into which a medal is inserted prior to the start of the game, a start lever 20 for starting the rotation of the first to third reels 15a to 15c, and a reel that is rotating during the game is stopped. Stop buttons 21a to 21c, a payout port 23 for paying out medals to the medal tray 22, a MAX bet button 25 for betting three medals when pressed once, a bet button for betting one medal when pressed once 26, and a payout button 27 for instructing the medals to be settled. When the payout button 27 is pressed, medals bet on the slot machine 11 and credited (stored) medals are paid out to the medal tray 22.

  In the slot machine 11, a maximum of three medals can be bet in one game. The player plays a game by betting medals arbitrarily selected from 1 to 3. When one medal is bet, the winning line 16 at the center in the horizontal direction is activated. When two medals are bet, the three winning effective lines 16 in the horizontal direction are activated. Then, when three medals are bet, a total of five winning active lines 16 are activated by adding two in the diagonal direction to three in the horizontal direction. When four or more medals are inserted from the medal insertion slot 19, medals up to the third are betted, and medals after the fourth are credited up to an upper limit of 50.

  The number of medals credited is displayed on a credit display section 28 provided below the first to third reels 15a to 15c. The credited medal is bet by operating the MAX bet button 25 or the bet button 26.

  The player inserts a medal into the medal insertion slot 19 or operates the MAX bet button 25 or the bet button 26 to bet a predetermined number of medals, and then presses the start lever 20 activated thereby. (Game start operation) to start the game. When the start lever 20 is pressed, a game start signal is input, the game is started, a random value is acquired and a winning combination lottery is performed, and any of the above-described multiple types of winning combinations or a loss is determined. . Then, when the winning combination lottery is finished, the variable display of symbols of the first to third reels 15a to 15c is started. The first to third reels 15a to 15c are stopped by pressing the stop buttons 21a to 21c, and it is determined whether or not the winning combination lottery in the winning combination lottery is won by the combination of the stopped symbols. One game is completed by completing various processes such as medal payout, game state transition, and replay processing, which are performed in accordance with the determination.

  FIG. 2 is a block diagram schematically showing the electrical configuration of the slot machine 11. The slot machine 11 includes a main board 40 that controls each part of the slot machine 11, a sub board 42 that controls the operation of the liquid crystal display 17, and a reel drive that controls the rotation of the first to third reels 15a to 15c. A controller 44 and a power supply circuit 46 for supplying power to these components are provided. A power switch 48 that selectively switches ON / OFF of the power of the slot machine 11 is connected to the power circuit 46. The main board 40, sub board 42, reel drive controller 44, power supply circuit 46, and power switch 48 are housed inside the storage box 12a.

  The power supply circuit 46 performs AC / DC conversion processing and voltage conversion processing on an AC commercial power supplied via a power cord (not shown). Then, the power supply circuit 46 supplies the converted power to each unit in accordance with the operation of the power switch 48. As a result, the slot machine 11 is activated.

  The main board 40 is provided with a main CPU (game control means) 50 and a main memory 51. The ROM area of the main memory 51 stores game execution programs and execution data. The main CPU 50 reads out the game execution program and execution data from the main memory 51 and performs processing, thereby comprehensively controlling each part of the slot machine 11.

  Further, the main CPU 50 has two control states: a game ready state in which a game can be executed and a game disable state in which a game cannot be executed. The main CPU 50 switches each control state based on inputs of various connected sensors and switches. As a method for making a game inoperable, for example, it is conceivable that a medal cannot be bet. If the medal is not bet, the operation of the start lever 20 is not validated, so that the game start operation cannot be performed and the game cannot be performed. Since the medal bet is executed at the beginning of the game, if the game cannot be executed by making it impossible to bet the medal, no additional processing is required and the game cannot be executed efficiently. Can be. For this reason, the main CPU 50 sets the slot machine 11 in a game impossible state by making it impossible to bet medals.

  The RAM area of the main memory 51 is used for temporary storage or rewriting of a winning flag (a flag indicating the type of winning combination won in the winning combination lottery) or data used for each game. The main memory 51 is configured by a non-volatile memory such as a flash memory, for example, and stores the winning flag and data when the power supply from the power supply circuit 46 is cut off.

  The main CPU 50 is connected with a medal sensor 60, a MAX bet signal sensor 61, a bet signal sensor 62, a start signal sensor 63, a stop signal sensor 64, a settlement signal sensor 65, a reset switch 66, and a hopper (payout means) 67. . These parts are also stored in the storage box 12a.

  The medal sensor 60 detects an appropriate medal inserted from the medal insertion slot 19 and inputs a medal detection signal to the main CPU 50. The main CPU 50 counts the number of inserted medals based on a medal detection signal from the medal sensor 60.

  The MAX bet signal sensor 61 detects that the MAX bet button 25 has been pressed, and inputs a MAX bet signal to the main CPU 50. The bet signal sensor 62 detects that the bet button 26 has been pressed, and inputs a bet signal to the main CPU 50. When the MAX bet signal or the bet signal is input, the main CPU 50 activates the winning pay line 16 as described above, and subtracts the number of medals bet from the number of medals displayed on the credit display unit 28. To do. The main CPU 50 accepts a game start signal only when a medal is bet by inputting any one of the medal detection signal, the MAX bet signal, and the bet signal. Thus, the operation of the start lever 20 is validated when a medal is bet.

  The start signal sensor 63 detects that the start lever 20 has been pressed. The start signal sensor 63 inputs a game start signal to the main CPU 50 when detecting the pressing of the start lever 20.

  The stop signal sensor 64 detects that the stop buttons 21a to 21c are pressed. When the stop buttons 21a to 21c are pressed, stop signals for the first to third reels 15a to 15c are individually input to the main CPU 50. The main CPU 50 determines whether or not the first to third reels 15a to 15c are rotating when a stop signal is input. The main CPU 50 controls the reel drive controller 44 when the first to third reels 15a to 15c are rotating, and the first to third reels 15a to 15c corresponding to the pressed stop buttons 21a to 21c. The stop control of 15c is performed. As the stop control of the first to third reels 15a to 15c, a known pull-in control is performed.

  In the pull-in control, the number of frames required until the first to third reels 15a to 15c are stopped ranges from 0 to 4 frames for 5 symbols including the symbols on the winning winning line 16, that is, a range of 5 frames (hereinafter, “ (Referred to as “retraction range”). If the winning symbol (the symbol corresponding to the winning combination won in the winning combination lottery) is included in the drawing range of 5 frames when the stop buttons 21a to 21c are pressed, the winning symbol is a winning line. Stop on 16.

  The settlement signal sensor 65 detects the depression of the payout button 27 and inputs a settlement signal (corresponding to the settlement instruction described in the claims) to the main CPU 50 for instructing the settlement of the bet medals and the credited medals. The main CPU 50 performs the settlement of the bet medals and the credited medals in response to the input of the settlement signal.

  One of the processes executed by the main CPU 50 is an illegal deterrence that shifts from a game-enabled state to a game-disabled state, pays out bet medals and credited medals, and continues the game-disabled state even after paying out. There is processing. The reset switch 66 inputs, to the main CPU 50, a reset signal for instructing the cancellation of the fraud suppression process when pressed. After starting the fraud suppression process, the main CPU 50 releases the fraud suppression process described later in response to the input of a reset signal from the reset switch 66, and returns the control state to the game-enabled state.

  The hopper 67 includes a storage tank that stores a plurality of medals, a payout mechanism that pays out medals stored in the storage tank, and the like. The main CPU 50 transmits a payout signal instructing the number of medals to be paid out to the hopper 67 when a payout occurs after winning a winning combination or when a payment is instructed by operating the payout button 27. When receiving the payout signal, the hopper 67 pays out the number of medals corresponding to the payout signal to the medal tray 22.

  Further, when there are no medals stored in the storage tank, the hopper 67 inputs a hopper empty error to the main CPU 50. When the main CPU 50 receives the hopper empty error from the hopper 67, the main CPU 50 shifts the control state to the non-gameable state.

  The main CPU 50 includes a winning combination determination unit 70, a timer 71, a settlement process execution unit (settlement process execution unit) 72, a fraud determination unit (unfair determination unit) 73, and a fraud suppression process execution unit (execution of fraud suppression process). Means) 74. The winning combination determining unit 70 includes a random number generator 70a that generates a random value. The winning combination determining unit 70 is activated in response to the input of the game start signal, and acquires the random value generated from the random number generator 70a. Then, the winning combination lottery is performed based on the acquired random number value, and any one of BB, the small combination, and the replay as the winning combination is determined.

  When any winning combination is won in the winning combination lottery, the main CPU 50 writes a winning flag indicating the type in the RAM area of the main memory 51. The BB flag is cleared when the BB wins, and the other flags are cleared when the winning game ends. Thereby, when BB is won, the right to win is carried over until BB wins. When the winning combination lottery is completed, the main CPU 50 rotates the first to third reels 15a to 15c, and starts displaying the symbols in a variable manner.

  The timer 71 starts timing in response to the input of the game start signal. When the game ends and a game start signal for the next game is input, the timer 71 records the time measured in the RAM area of the main memory 51 as a measured value. Thus, the timer 71 measures the input interval of the game start signal. In addition, when the measured value is recorded, the timer 71 resets the count once and then starts counting again, and thereafter repeats the above processing every time a game start signal is input.

  The settlement process execution unit 72 is a period in which no game is performed, that is, a period excluding a period from the operation of the start lever 20 until the process (payout, game state transition process, replay process, etc.) associated with winning determination is completed. In response to the input of the adjustment signal from the adjustment signal sensor 65, the medal adjustment process is executed. When the settlement signal is input, the settlement process execution unit 72 first shifts the main CPU 50 to a game impossible state. Thereafter, the settlement processing execution unit 72 settles the bet medals and the credited medals by transmitting to the hopper 67 a payout signal according to the number of medals bet and credited medals. Then, the settlement process execution unit 72 returns the main CPU 50 to the game-ready state in response to the completion of the medal payout by the hopper 67.

  Further, after the payout processing execution unit 72 transmits a payout signal to the hopper 67, the payout valid line 16 is invalidated, the number of medals displayed on the credit display unit 28 is set to 0, and the payout sound Is output from the speaker 68.

  The fraud determination unit 73 determines whether or not a game start signal is input at a predetermined interval continuously several times based on each measurement value recorded in the RAM area of the main memory 51 after the measurement by the timer 71 is performed. Judgment is made. When the measurement value is acquired by the timer 71, the fraud determination unit 73 calculates a difference between the measurement value and the previous measurement value recorded in the RAM area of the main memory 51, and the difference is within a predetermined range. At a certain time, it is determined that the input interval of the previous game start signal and the input interval of the current game start signal are constant. Then, when this determination is repeated a plurality of times, the fraud determination unit 73 determines that the game start signal is input at a constant interval continuously a plurality of times.

  In order for a player to play a game, it is not possible to play a game simply by a bet operation using the bet button 26, and an operation for inserting a medal into the medal insertion slot 19 is required. In addition, when a small role is won with less than 50 credits, credit addition processing is executed, and when a small role is won with 50 credits, a medal is paid out. Processing is executed. In general, the input interval of the game start signal varies depending on the number of payouts and the presence / absence of the payout. Therefore, when the player is playing a game normally, it is unlikely that a game start signal is input at a constant interval continuously several times.

  On the other hand, when an illegal act is performed by the driving machine, the medal detection signal, the game start signal, and the stop signal are directly input from the driving machine at a predetermined timing. The driving machine inputs signals to the main board and also receives signals from the main board. When the payout is made, the driving machine accepts the payout signal and immediately outputs the payout completion signal to the main board, so even if the payout is made, the credit addition process and the medal The payout process is not performed, and the input timing of the game start signal tends to be the same. For this reason, the fraud determination unit 73 determines that fraud by the driving machine has been performed when a game start signal is input at a predetermined interval continuously a plurality of times.

  The fraud suppression processing execution unit 74 executes the above-described fraud suppression processing when the fraud determination unit 73 determines that fraud has been performed. When the fraud determination unit 73 determines fraud, the fraud suppression processing execution unit 74 first shifts the main CPU 50 to the game impossible state. Thereafter, the fraud suppression processing execution unit 74 transmits a payout signal corresponding to the number of bets and medals bet to the hopper 67 and outputs a payout sound from the speaker 68 to thereby place the bet medals. And settle the credited medals. Then, even after the medal payout by the hopper 67 is completed, the fraud suppression processing execution unit 74 continues the game-disabled state until the reset signal from the reset switch 66 is input.

  As described above, the main CPU 50 disables the game by making it impossible to bet medals when the game is disabled. Specifically, when the medal detection signal is input from the medal sensor 60 when the main CPU 50 is in an inoperable state, the main CPU 50 transmits a payout signal to the hopper 67 without betting a medal, and detects the input medal. The number of medals corresponding to the signal is paid out to the hopper 67. In addition, when the fraud suppression process is executed, the credited medal is paid out, so that no medal is bet even when the MAX bet signal or the bet signal is input.

  Note that the method for making it impossible to bet medals is not limited to the above, and for example, a blocker of a selector may be operated to make it impossible to manually place medals. In addition, a credited medal may not be bet by disabling the operation of the MAX bet button 25 or the bet button 26 by not accepting the MAX bet signal or the bet signal. Further, although the MAX bet button 25 and the bet button 26 can be operated, it is possible that the bet of medals is not performed only by the credit subtraction.

  The sub board 42 includes a sub CPU 52 and a sub memory 53. The sub CPU 52 controls the operation of the liquid crystal display 17 and the speaker 68 by controlling the operation of the sub substrate 42. In the ROM area of the sub memory 53, a control program and data for driving the liquid crystal display 17 and the speaker 68 are stored. The sub CPU 52 is electrically connected to the main CPU 50, and a game start signal is input from the main CPU 50. The sub CPU 52 reads a control program and data from the ROM area of the sub memory 53 in response to the game start signal, and controls the operation of the liquid crystal display 17.

  The game start signal input from the main CPU 50 to the sub CPU 52 includes the winning lottery result and winning combination winning information. When the sub CPU 52 wins a winning combination such as BB, replay, and small role, the sub CPU 52 writes a flag corresponding to the winning combination such as a BB flag, a replay flag, and a small role flag in the RAM area of the sub memory 53. When the sub-CPU 52 writes the BB flag in the sub-memory 53, the sub-CPU 52 carries over clearing of the BB flag until winning the BB, and clears the BB flag according to the winning of the BB. On the other hand, when the sub CPU 52 writes a flag other than the BB flag in the sub memory 53, the sub CPU 52 clears the flag in accordance with the end of the game won for the winning combination regardless of the presence or absence of a winning combination.

  The sub CPU 52 displays an effect screen corresponding to the game mode on the liquid crystal display 17 based on the state of the flag written in the RAM area of the sub memory 53. Similarly to the main memory 51, the sub memory 53 is configured by a non-volatile memory such as a flash memory, for example, and stores the state of each flag when the power supply from the power supply circuit 46 is cut off. .

  The speaker 68 outputs sound corresponding to the sound signal input from the sub CPU 52. The sub CPU 52 causes the speaker 68 to output various sounds in accordance with the game situation so that the player's interest can be raised. Further, when the sub CPU 52 pays out medals by the hopper 67, the sub CPU 52 outputs a payout sound for notifying the payout of medals from the speaker 68.

  Next, the operation of the slot machine 11 configured as described above will be described with reference to the flowchart shown in FIG. In order to play a game in the slot machine 11, first, any one of the medal detection signal, the MAX bet signal, and the bet signal is input to the main CPU 50, and a predetermined number of medals are bet to activate the winning effect effective line 16. Thereafter, a game start signal is input to the main CPU 50 to start the game.

  When a game start signal is input to the main CPU 50, the timer 71 measures the input interval of the game start signal. Thereafter, based on each measurement value recorded in the RAM area of the main memory 51, the fraud determination unit 73 determines whether or not the game start signal is input at a predetermined interval continuously several times.

  If it is determined that a plurality of consecutive winning combinations have not been input, the winning combination determination unit 70 draws a winning combination, and determines any of a plurality of types of winning combinations or a loss. When the winning combination lottery is completed, the main CPU 50 rotates the first to third reels 15a to 15c, and starts the variable display of symbols. Thereafter, when a stop signal is input, the main CPU 50 controls the reel drive controller 44, and performs stop control of the first to third reels 15a to 15c according to the stop signal.

  When the main CPU 50 stops all of the first to third reels 15a to 15c, the main CPU 50 wins the winning combination selected by the combination of symbols of the first to third reels 15a to 15c stopped on the winning effective line 16. Determine whether or not. When the main CPU 50 determines that the winning combination has been won, the main CPU 50 performs processing corresponding to the winning combination. For example, when winning a small combination, the number of medals corresponding to the small combination is paid out and a payout sound is output from the speaker 68. Further, when winning a replay, the same number of medals as the bet in the game are automatically bet (the medal held by the player is not reduced). Further, when a bonus such as BB is won, a transition to the bonus state is performed. Thus, one game is completed.

  On the other hand, when the fraud determination unit 73 determines that the game start signal is input at a constant interval continuously several times, the fraud suppression processing execution unit 74 executes the fraud suppression processing. When executing the fraud suppression process, the fraud suppression processing execution unit 74 shifts the main CPU 50 to the non-gameable state, and then pays out bet medals and credited medals to the hopper 67 and outputs a payout sound to the speaker 68. Output from. Then, the fraud suppression processing execution unit 74 stops the output of the payout sound in response to the completion of the medal payout by the hopper 67.

  In the fraud deterrence process, the inoperable state continues until the release is instructed by pressing the reset switch 66. Therefore, even when using a driving machine, it takes a lot of time and effort to win a bonus combination such as BB. Will start. In addition, since the betting medals and the credited medals are settled, it is possible to generate trouble for the employees who work illegally to clear the paid-out medals. Since BB has a high profit and a low winning probability, BB is targeted by an unauthorized device (so-called sensory device) that notifies the player of the winning timing by vibration or the like, but this can be prevented by the present invention.

  When the medal detection signal is input to the main CPU 50 when the game is not possible, a medal corresponding to the medal detection signal is paid out without paying out a medal and a payout sound is output. When a game is played by a driving machine, a medal detection signal is input by electrical control without actually inserting a medal. Therefore, if the payout is performed as described above, the medal stored in the hopper 67 Someday it will be empty and you will get a hopper empty error. When a hopper empty error occurs, simply pressing the reset switch 66 does not return to the playable state and the hopper 67 needs to be replenished with medals. .

  When the reset signal is input to the main CPU 50, the fraud suppression processing execution unit 74 cancels the execution of the fraud suppression processing and returns the main CPU 50 to a game-ready state. At this time, since the reset switch 66 is housed in the storage box 12a, the front door 13 must be opened each time the reset switch 66 is pressed, which further increases the troublesome employees. be able to.

  As described above, according to the present embodiment, even when a driving machine is used, it takes a lot of time and effort, so that it is possible to obtain a high deterrent effect against fraud using the driving machine. .

  In the above embodiment, when paying out a bet and a credited medal by executing the fraud deterrence process, the output of the payout sound is stopped when the payout ends, but the payout is completed. The payout sound may be left to be output later. When a medal detection signal is input in this state, the type of payout sound may be changed or the volume may be increased.

  Next, a second embodiment of the present invention will be described with reference to the flowchart shown in FIG. Note that the same functions and configurations as those of the above embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. After the main CPU 50 bets a predetermined number of medals and activates the winning winning line 16, the main CPU 50 causes the winning combination determination unit 70 to draw a winning combination according to the input of the game start signal. The winning combination determining unit 70 obtains a random value generated from the random number generator 70a. Then, the winning combination lottery is performed based on the acquired random number value, and one of a plurality of types of winning combinations or a loss is determined. The winning combination determination unit 70 records the acquired random number value in the RAM area of the main memory 51 after performing the winning combination lottery.

  After the winning combination lottery is completed, the fraud determination unit 73 has acquired a random value of the same or approximate value consecutively a plurality of times based on the random number of the past several times recorded in the RAM area of the main memory 51. Determine whether or not.

  The fraud determination unit 73 calculates the difference between the random value acquired this time and the random value acquired last time, and determines that the random value acquired this time is the same as the previous time when the difference is zero. Further, the fraud determination unit 73 calculates a difference between the random value acquired this time and the random value acquired last time, and if the difference is equal to or less than a predetermined value, the random value acquired this time is compared with the previous random value. Judged to be an approximate value. Then, when this determination is repeated a plurality of times, the fraud determination unit 73 determines that a random value having the same or approximate value has been acquired continuously a plurality of times.

  In addition to the type in which a game start signal is input at regular intervals, a type in which a game start signal is input aiming at the timing of winning BB is known. In such a type of driving machine, since the input interval of the game start signal is not always constant, the first embodiment cannot detect fraud. On the other hand, when aiming at the timing for winning BB, the random number value that is the same or approximate to the random value winning BB is always obtained, so determination based on the random value as described above By performing this, it is possible to detect fraud of the type in which a game start signal is input aiming at the timing of winning BB.

  When the fraud determination unit 73 determines that the same or approximate random number is not acquired, the main CPU 50 rotates the first to third reels 15a to 15c and executes the game. To do. On the other hand, if it is determined by the fraud determination unit 73 that a random value having the same or approximate value has been acquired in succession a plurality of times, the fraud suppression processing execution unit 74 performs the fraud suppression process as in the first embodiment. Executed. Thereby, according to this embodiment, the effect similar to the said 1st Embodiment can be acquired with respect to the driving machine of the type which inputs a game start signal aiming at the timing which wins BB.

  In addition, in the case where fraud is detected by using a random value in this way, it is possible to obtain a deterrent effect not only for the driving machine but also for the sensory device. There are two ways to use the sensation device: when aiming for a bonus combination and when aiming for a small combination.

  When aiming for a bonus combination, if the bonus combination is won, there is no point in winning the bonus combination in the next game, so the process until the bonus combination is won is particularly important. Here, in order to win a bonus combination with a sensory device, it is actually difficult to hit with one shot, and from a random value different from the bonus combination, gradually close to a random value to be selected for the bonus combination for each game It is necessary to continue. For this reason, when aiming for a bonus combination, a random value approximated in the process is acquired.

  On the other hand, when aiming for a small role, the same process as when aiming for a bonus role becomes a problem, but in addition, after setting the random number value of the targeted small role, aim for the corresponding small role every game. This also becomes a problem, and in this case as well, an approximate random value is acquired. Therefore, according to the present embodiment, it is possible to appropriately detect fraud and suppress it when the sensory device is used in any of the above two patterns.

  In the present embodiment, when a medal detection signal is input to the main CPU 50 when the game is disabled, a medal corresponding to the medal detection signal is paid out without paying out a medal. Added sound output. The payout sound has a relatively high volume compared to the sound effect during the game. For this reason, if the payout sound is frequently output in response to the input of the medal detection signal, it is possible to notify the employee of the pachinko parlor that fraud by the sensory device is being performed.

  Note that the volume of the payout sound that is output during the execution of the fraud deterrence process is higher than the payout sound that is output when a payout is made by winning the winning combination or when payout is instructed by operating the payout button 27. You may make it enlarge. Further, without being limited to the payout sound, for example, a dedicated warning sound is output from the speaker 68 or a warning message is displayed on the liquid crystal display 17 to notify that fraud has been performed. Good.

  Next, a third embodiment of the present invention will be described with reference to the flowchart shown in FIG. After the main CPU 50 bets a predetermined number of medals and activates the winning winning line 16, the main CPU 50 causes the winning combination determination unit 70 to draw a winning combination according to the input of the game start signal. The winning combination determining unit 70 obtains a random value generated from the random number generator 70a. Then, the lottery table 90 stored in the main memory 51 is referred to based on the acquired random number value.

  As shown in FIG. 6, in the lottery table 90, a plurality of winning combinations and loses are associated with random numbers. The random value is represented by an integer from 0 to 65535. Each winning combination and loser is assigned a random value in a predetermined range. When the winning combination determining unit 70 acquires a random value from the random number generator 70a, the winning combination determining unit 70 refers to the lottery table 90 and determines a winning combination or a loss according to the random value. The winning combination determining unit 70 records the acquired random number value in the RAM area of the main memory 51 after performing the winning combination lottery.

  When the winning combination lottery is completed, the fraud determination unit 73 obtains a random number corresponding to a specific winning combination continuously several times based on the past random number values recorded in the RAM area of the main memory 51. It is determined whether or not. For example, the fraud determination unit 73 determines that the random number value corresponding to the bell, which is a small role, has been acquired a plurality of times in succession when each of the past random number values is within the range of 651 to 9950.

  When it is determined by the fraud determination unit 73 that the random value corresponding to the specific winning combination has not been acquired, the main CPU 50 rotates the first to third reels 15a to 15c to play the game. Execute. On the other hand, if it is determined by the fraud determination unit 73 that a random value corresponding to a specific winning combination has been acquired a plurality of times, fraud suppression processing is executed by the fraud suppression processing execution unit 74 as in the above embodiments. Is done. In this way, if fraud is detected by determining whether or not a random value corresponding to a specific winning combination has been acquired a plurality of times in succession, fraud targeting a small role using a sensory device is more appropriate. Can be detected.

  As shown in FIG. 7, a changeover switch 92 for inputting a switching signal to the main CPU 50 according to an operation is provided, and the fraud determination unit 73 determines whether or not a game start signal is input at a predetermined interval continuously several times. To determine whether or not a random value of the same or approximate value has been acquired continuously multiple times, or whether the random value corresponding to a specific winning combination is acquired continuously multiple times It may be possible to selectively switch whether or not the fraud determination unit 73 determines whether or not it has occurred.

  For example, a dial-type switch or a slide-type switch that moves to three positions can be used as the change-over switch 92 that is a change-over operation means. The switch is not limited to a switch and may be a lever or a plurality of buttons. The changeover switch 92 is preferably provided inside the storage box 12a so that only a player or other employee can operate.

  In each of the above embodiments, both the bet medals and the credited medals are settled during the settlement process. However, the medals that are settled during the settlement process are credited with the bet medals. Only one of the medals is acceptable.

  In each of the above-described embodiments, a game cannot be played by making it impossible to bet medals. However, the game disabled state is not limited to this. For example, after a bet on medals is received, a game start signal is received. It may be possible to prevent the game from being performed, or it may be possible to prevent the game from being performed by not accepting the stop signal after the symbol change display.

  In each of the embodiments described above, the fraud suppression process is canceled by pressing the reset switch 66. However, the present invention is not limited to this, for example, by operating the power switch 48 to turn the slot machine 11 on / off. The fraud suppression process may be canceled.

  In each of the embodiments described above, the present invention is applied to a slot machine that drives a reel. For example, a slot machine that rotates a reel displayed by a liquid crystal display (to display a variable display of symbols on the liquid crystal display), a pachinko ball The present invention may be applied to a slot machine used as a game medium.
