Description

  The present invention relates to a gaming machine, and more particularly, to a gaming machine configured to store a gaming state in a nonvolatile manner and to restore the gaming state when the power is turned off based on the memory when the power is turned on. is there.

  In gaming machines called pachinko machines and pachislot machines, random numbers are generated internally, and whether or not the game is successful is determined according to the value of a random number counter (hereinafter simply referred to as a random number) acquired at the time of starting winning or lever operation. For example, in a pachinko machine, a random number is acquired at the time of starting winning, and if this value is a predetermined jackpot value (for example, 7), a jackpot game is generated. The random number counter is configured to generate a jackpot value with a predetermined probability, but is designed to generate a jackpot value aperiodically so as not to be shot. However, when the power is turned on, there are many gaming machines that generate a random number with an initial value unique to the random number counter, and in this case, the timing at which the jackpot value is generated can be known only for the first time. Abuse of this may result in a fraudulent act of attaching a fraudulent board to a gaming machine and aiming at a jackpot value by turning off and on the power.

  In order to prevent such fraud, Patent Document 1 waits until the value of the random number counter matches the identification number unique to the pachinko machine, so that the timing from when the power is turned on until the jackpot value is generated is set for each pachinko machine. It is changing.

However, even in the invention described in Patent Document 1, once the identification number of the pachinko machine is specified, the identification number does not change. is there. There are many gaming machines in which the gaming state is stored in a nonvolatile manner in a RAM or the like, and when the power is turned off and then turned on again, the gaming state at the time of turning off the power is restored based on the RAM or the like. When the RAM clear operation is received, the random number is initialized, and the same fraud may be performed as described above.
The present invention has been made in view of the above problems, and an object thereof is to prevent fraudulent acts that misuse the power on / off of a gaming machine.

When it is determined by the second random number generation means and the second operation determination means that the clear switch has been operated, a third variable value that is a random number generated by the second random number generation means is acquired. When the second non-operation determining unit determines that the clear switch has been moved to a non-operated state, the second non-operation determining unit further acquires a fourth variable value that is a random number generated by the second random number generating unit, The second The clear switch is not operated by the second initial value setting means for setting the numerical value calculated based on the variable value and the third variable value as the initial value of the first random number and the first operation determining means. A recovery means for recovering the gaming state of the gaming machine based on the data held in the RAM.

According to a third aspect of the present invention, there is provided a RAM capable of storing data in a non-volatile manner, first random number generating means for generating a first random number used for determining whether or not the game is successful, and at least the validity based on the first random number In a gaming machine comprising control means for performing determination control and a clear switch operated when clearing the contents held in the RAM, it is estimated whether the clear switch has been operated when the gaming machine is energized.

Two random number generating means;
If it is determined by the first non-operation determining means that the clear switch has transitioned to a non-operated state, a fifth variable value that is a random number generated by the second random number generating means is acquired, and the second When it is determined by the operation determining means that the clear switch has been operated, a sixth variable value that is a random number generated by the second random number generating means is acquired, and the second non-operation determining means When it is determined that the clear switch has transitioned to a non-operated state, the seventh variable value, which is a random number generated by the second random number generation means, is acquired, and the seventh variable value, A third initial value setting means for setting a numerical value calculated based on at least two of the variable value and the fifth variable value as an initial value of the first random number; and the first operation determining means, Clear water If it is determined that switch has not been operated, characterized in that a recovery means for recovering the gaming state of the gaming machine based on the data held in the RAM.

According to a fourth aspect of the present invention, in the gaming machine according to any one of the first to third aspects, the first non-operation determining unit determines that the clear switch has transitioned to a non-operated state. After that, if the second operation determination unit does not determine that the clear switch has been operated even after a predetermined time has elapsed, the recovery unit stores the data stored in the RAM. Based on the above, the gaming state of the gaming machine is restored.
According to a fifth aspect of the present invention, in the gaming machine according to any one of the first to fourth aspects, the first non-operation determining unit determines that the clear switch has transitioned to a non-operated state. Further, there is provided an informing means for informing an operator of the clear switch.

In the gaming machine according to claim 1, in order to perform the RAM clear, the clear switch is operated from a state where the gaming machine is not energized and is energized as it is. Then, the first operation determination means determines that “the clear switch was operated during energization”. Then, a 1st non-operation determination means determines whether it changed to the state where the clear switch is not operated. When it is determined that the clear switch has not been operated, the first initial value setting means acquires the second random number. The second random number is generated by the second random number generation means, and the second random number generation means is activated when the gaming machine is energized and updating the random number value (second random number) as time elapses. generate. This second random number is referred to herein as a first variable value.
When the second operation determining means determines that the state has changed from the state where the clear switch is not operated to the state where the clear switch is operated again, the first initial value setting means again returns the second random number (second variable). And a numerical value calculated from the second variable value and the previously acquired first variable value is set as the initial value of the first random number used for the determination of success / failure.

That is, in order to perform an operation for setting the initial value of the first random number (for example, RAM clear, hereinafter also referred to as RAM clear), the game machine is energized while the clear switch is operated, and once the operation for the clear switch is canceled, The clear switch will be operated. Naturally, the time when the operation to the clear switch is canceled and the time when the operation is performed again are different, and the time interval is considered to be different for each RAM clear operation. In addition, the value of the second random number (the first variable value and the second variable value) updated with the passage of time can almost be the same as the value in the RAM clear switch previously performed at both time points. However, it is extremely rare that the value calculated from these (the value set as the initial value of the first random number) is the same as the previously calculated value in the RAM clear. Therefore, it can be expected that the first random number becomes a different value every time the RAM is cleared. As a result, the timing at which the jackpot value is generated changes every time the RAM is cleared even in the same gaming machine, and the above-described fraudulent acts are extremely difficult.
When the first operation determination means determines that “the clear switch has not been operated when energized”, the recovery means determines the gaming state of the gaming machine based on the data held in the RAM. Since the value is restored, the value of the first random number is also restored to the value at the time of power-off, and it is still difficult to cheat.

  Note that the initial value of the first random number is not limited to the first value that can be output as the first random number. For example, a value called a seed (random number seed) generally used for generating a random number is also included in the initial value of the first random number. The value to be set is calculated from the value of the second random number. As a specific example of this “calculation”, the difference between the second variable value and the first variable value, the sum, the product, one is divided by the other. From simple things such as the remainder, to those that perform calculations using other numerical values. Examples of other numerical values include a value obtained by adding 1 to the maximum value that can be set as the initial value of the first random number. If, for example, the remainder obtained by dividing the difference between the second variable value and the first variable value is calculated with this value, the calculated value becomes 0 or more and less than the maximum value, so that it is set as the initial value of the first random number as it is. Can do. Further, when only the first variable value is used, it is referred to as “calculated based on the second variable value and the first variable value”. For example, if the second variable value is used as it is, it can be interpreted as second variable value + 0 × first variable value. Also, a table in which the first variable value and the second variable value are associated with the numerical value to be set as the initial value of the first random number in advance is referred to as “calculation” here. I will call it.

  In addition, as the “operation” for the clear switch, various modes are conceivable depending on the type of the clear switch. If the clear switch is a push button that performs momentary operation, pressing is an operation, and if it is a slide switch, it is an operation to slide its knob in one direction. It is an operation to rotate one side. The operator who clears the RAM of the gaming machine of the present invention needs to stop the operation of the clear switch, which is based on a slide knob if the clear switch is a slide switch. In the case of a lever, it is a natural operation of rotating a lever rotated in one direction in the opposite direction. In particular, if the clear switch is a push button for a momentary operation, it is preferable because the non-operating state can be achieved simply by releasing the hand or finger from the button.

  The difference between the gaming machine according to claim 2 and the gaming machine according to claim 1 is that the latter is the second random number value when the clear switch is first in the non-operating state, and then the clear switch. On the other hand, the initial value of the first random number is set based on the value of the second random number when the switch is in the operating state, whereas the former is the first value when the clear switch is first switched from the non-operating state to the operating state. On the basis of the value of the second random number (third variable value) and the value of the second random number (fourth variable value) when the clear switch is in a non-operation state next time, the second initial value setting means sets the first random number The initial value of is set.

That is, in order to set the initial value of the first random number in this gaming machine, the gaming machine is energized while the clear switch is operated, once the operation for the clear switch is canceled, the clear switch is operated again, The operation for this clear switch is cancelled. The point in time when the clear switch is operated (except when the power is turned on) and the point in time when the operation is canceled are naturally different, and the time interval is also considered to be different for each RAM clear operation. Therefore, similarly to the gaming machine according to the first aspect, the timing at which the jackpot value is generated is changed every time the RAM is cleared even in the same gaming machine, and the above-described fraud is extremely difficult.
The third variable value according to claim 2 and the second variable value according to claim 1 are generally not the same in numerical value, but the acquisition process is the same. Even if the clear switch is operated after the game machine is energized without operating the clear switch and the operation is canceled, the initial value of the first random number is not set. Because the first operation determining means determines that “the clear switch has not been operated at the time of energization”, even if the clear switch is operated after that, the clear switch is not operated by the first non-operation determining means. This is because it is not determined whether or not a transition has been made to a non-existing state. As a result, the second operation determining means does not determine whether or not the transition to the state in which the clear switch has been operated has been made, so whether or not the second non-operation determining means has transitioned to the state in which the clear switch has not been operated. No judgment is made. That is, the initial value of the first random number is not set.

The gaming machine according to claim 3 is close to a combination of the gaming machines according to claims 1 and 2. That is, in the gaming machine according to claim 3, the value of the second random number (fifth variable value) when the clear switch is first in the non-operation state and the next time when the clear switch is in the operation state. The third initial value setting means based on the value of the second random number (sixth variable value) and the value of the second random number (seventh variable value) when the clear switch is in the non-operation state next time. Sets the initial value of the first random number. However, the present invention is not limited to the mode using these three variable values, and the value set as the initial value of the first random number value is calculated using at least two.
As a calculation method, the three variable values are summed, and the three variable values are multiplied to obtain a difference between the fifth variable value and the seventh variable value. Various things can be assumed, such as obtaining a remainder obtained by dividing the maximum value that can be set as a value by adding “1”.

  In order to perform the RAM clear in this gaming machine, the gaming machine described in claim 2 may be used. That is, the gaming machine may be energized while the clear switch is operated, once the operation on the clear switch is canceled, the clear switch is operated again, and further the operation on the clear switch is canceled. When the clear switch operation is canceled, when the operation is performed again, and further when the operation is canceled, the time interval (from the cancellation of the operation to the restart, from the restart of the operation to the second cancellation, 3 types from the first cancellation to the second cancellation) are considered to be different for each RAM clear operation. Therefore, similarly to the gaming machines according to claims 1 and 2, the timing at which the jackpot value is generated changes every time the RAM is cleared even in the same gaming machine, and the above-described fraudulent act becomes extremely difficult.

In any of the present inventions described above, in order to clear the RAM, the clear switch needs to be operated twice. However, the operator may forget the second operation. In this case, since the clear switch has been pressed at the time of energization, the game state cannot be restored, but the second variable values (third variable value, sixth variable value) cannot be obtained. There is a risk that the RAM cannot be cleared and the control is lost. In order to prevent this, in the present invention according to claim 4, it is determined that the first non-operation determining means has made a transition to a state in which the clear switch is not operated, with energization performed while the clear switch is operated. After that, if the second operation determination means does not determine that the clear switch has been operated even after a predetermined time has elapsed, the recovery means may perform the operation based on the data held in the RAM. Restore the gaming state of the gaming machine. As a result, the gaming machine does not fall into an uncontrollable state. As a result, the initial value of the first random number that should originally be set is not set. In order to do this, the energization is again canceled and the initial value of the first random number is set.
Also, using this specification, it is possible to cancel the setting of the initial value of the first random number in the middle of the setting operation of the initial value of the first random number. That is, when the power is inadvertently operated while operating the clear switch, even though the RAM should not be cleared, stop the operation to the clear switch and wait for the predetermined time to elapse. That's fine. If it does so, RAM state will not be performed, but the gaming state at the time of a power failure will be restored.

  Even with this configuration, there is a possibility that the operator will make a mistake in the RAM clearing operation. For example, if the operation of the clear switch is stopped too early during energization, the first operation determination means may determine that “the clear switch was not pressed during energization”. Even if the second operation is performed on the clear switch in this state, the RAM is not cleared as described above. If the operator notices that "RAM clear failed", the game machine may be turned off and try again, but there is a possibility that this failure will not be noticed. This is especially true because some gaming machines have no difference in appearance between when the RAM is cleared and when power is supplied without clearing the RAM. According to a fifth aspect of the present invention, the first non-operation determination unit includes a notification unit that notifies the operator of the clear switch that it has been determined that the clear switch has not been operated. According to this gaming machine, when the operator stops the operation of the clear switch at the time of energization, the operator confirms that the notification by the notification means has been performed and then performs the second operation to the clear switch. Clearing can be performed reliably. If the RAM clear operation fails, the notification operation is not performed, so that it is understood that the RAM clear operation has failed. The RAM can be reliably cleared by once turning off the power supply and performing the RAM clear operation again.

When the RAM clear is executed, a notification operation (referred to as a second notification operation) different from the notification operation (referred to as a first notification operation) is performed, or the first notification operation is terminated. (In this aspect, if the first notification operation is continued until the RAM is actually cleared), the RAM can be cleared more reliably. The meaning of the notification changes, but when applied to the gaming machine according to claim 4, a configuration in which the first notification operation is stopped when the predetermined time has elapsed, or the second notification operation is performed. It is good also as composition which performs. In the former configuration, when it is desired to cancel the RAM clear operation halfway, it is only necessary to wait for the completion of the first notification operation that occurs after energization. In the latter configuration, it is only necessary to wait for the second notification operation to be started, so that the operator can confirm that the RAM is not cleared (successful cancellation).
As a notification mode of the notification means, it is conceivable to light or blink a lamp, to output a sound, or the like. In addition, since the power switch and clear switch of the gaming machine are usually provided on the back side of the gaming machine, it is often difficult for a person who wants to clear the RAM to see the front side of the gaming machine. Therefore, there is a high possibility that it is not effective to make a notification using equipment (liquid crystal screen, movable object, etc.) provided on the front side of the gaming machine.

In addition to this, it is also conceivable to use a configuration in which the detection signal of the payout sensor 21 is input to the main control board 80 and the payout control board 81 and both the main control board 80 and the payout control board 81 count the prize balls.

  The payout control board 81 receives signals from the glass frame opening switch 35, the inner frame opening switch 36, the full switch 22, and the ball break switch 23, and the full switch 22 indicates that the lower plate 63 is full. And when a signal indicating that there are few or no game balls in the ball tank is input by the ball break switch 23, the payout motor 20 is stopped and the payout operation of the prize ball is stopped. Note that the full switch 22 and the ball break switch 23 are also configured to continue outputting signals until the state is cleared, and the payout control board 81 causes the payout motor 20 to stop being output. Restart the drive.

  Further, the payout control board 81 communicates with the prepaid card unit via the game ball lending device connection terminal 24 to operate the payout motor 20 and discharge the lending balls. The paid-out lending ball is detected by the payout sensor 21, and the detection signal is input to the payout control board 81. The game ball lending device connection terminal 24 is also connected to the checkout display board 25 so as to be capable of two-way communication. The checkout display board 25 requests a checkout button for paying out a game ball, and a checkout. A return button and a balance indicator are connected.

Also, the payout control board 81 transmits information relating to the winning ball, information indicating the open / closed state of the frame (inner frame, front frame), etc. to the hall computer via the external connection terminal 78, and also to the launch control device 84. Send a fire stop signal.
In this embodiment, the game balls are paid out. However, the game balls generated in accordance with winnings or the like may be stored without being paid out.

The launch control device 84 controls the launch motor 30 to launch the game ball into the game area 3. In addition to the payout control board 81, the launch control device 84 receives a rotation amount signal from the launch handle, a touch signal from the touch switch 28, and a launch stop signal from the launch stop switch 29.
The rotation amount signal is output when the player operates the launch handle, the touch signal is output when the player touches the launch handle, and the launch stop switch signal is generated when the player presses the launch stop switch 29. Is output. If the touch signal is not input to the launch control device 84, the game ball cannot be launched, and if the launch stop switch signal is input, the game ball cannot be launched even if the player touches the launch handle. It has become.

  The sub integrated control device 83 corresponds to the sub control device, receives data and commands transmitted from the main control board 80, distributes them to data for effect display control, sound control and lamp control, The display control command and the like are transmitted to the effect design control device 82, and the sound control and lamp control are distributed to each control part (function unit as a sound control device and a lamp control device) included in the display control command 82. Then, the function unit as the sound control device controls the sound output from the speaker by operating the sound LSI based on the data for sound control, and the function unit as the lamp control device is based on the data for lamp control. The various LED and lamp 26 are controlled by operating the lamp driver. In addition, an effect button 67 is connected to the sub integrated control device 83, and when the player operates the effect button 67, a signal is input to the sub integrated control device 83.

Bi-directional communication is possible between the sub integrated control device 83 and the production symbol control device 82.
The effect symbol control device 82 displays the effect symbol display based on the data and commands received from the sub integrated control device 83 (both those transmitted from the main control board 80 and those generated by the sub integrated control device 83). The device 6 is controlled to display an effect image such as a pseudo symbol on the screen 6a.

  FIG. 5 shows a power supply and signal system between the power supply board 85 and each part of the gaming machine including the main control board 80 and the payout control board 81. The power supply board 85 of each pachinko machine receives the AC 24V power provided on the pachinko parlor side via the power switch 671, and the power generation circuit 672 receives the main control board 81 shown in FIG. Power is supplied to each part of the gaming machine including the control board 81. The power switch 671 is of a type that maintains its state when turned on or off.

  The full-wave 24V output in the power generation circuit 672 is input to the power supply voltage monitoring circuit 673, and the reset signal generation circuit 674 outputs or cancels the reset signal based on the detection result of the presence / absence of the full-wave 24V output by the power supply voltage monitoring circuit 673. . That is, the power supply voltage monitoring circuit 673 determines that the full-wave 24V output is stopped if the non-output state higher than the predetermined reference voltage is maintained for a predetermined time, and the reset signal generation circuit 674 responds to the determination that the full-wave 24V output is stopped. Output a reset signal. On the other hand, when full wave 24V output is started, the reset signal is canceled. Here, the output of the reset signal is to output a low level signal, and the release is to change from the low level to the high level. Note that the reset signal is released after a delay time Ta from the time when the full-wave 24V output is detected.

  The output of the reset signal generation circuit 674 is output to reset terminals of the CPUs 611 and 621 of the main control board 81 and the payout control board 81, respectively.

  A power failure signal generation circuit 675 is provided with the output of the power supply voltage monitoring circuit 673 as an input, and a power failure signal is output to the NMI terminals of the control board CPUs 611 and 621 when the power is interrupted such as a power failure. The power failure signal is a signal that changes from a high level to a low level when the power is cut off, and the output timing is set so that it is output before the reset signal is output.

  The power supply board 85 is configured to generate a DC5V backup power supply (VBB) by a backup power supply generation circuit 678 including a capacitor, and the backup power supply (VBB) output is the backup of each control board CPU611, 621. The data is output to the terminal (VBB), and the contents stored in the RAM of each control board CPU 611 and 621 are retained in the event of a power failure, as will be described later.

  The power supply board 85 also includes a RAM clear switch 676. A RAM clear switch 676 is provided to clear the contents stored in the RAMs 615 and 625 of the CPUs 611 and 621.

  The RAM clear switch 676 is a push button type that is turned on only when pressed, and if the RAM clear switch 676 is on, the RAM clear signal generation circuit 677 controls the RAM clear signal, which is a high level signal, as the main control. The data is output to the input ports 613 and 623 of the board 80 and the payout control board 81 for a predetermined time (described later). Here, the delay time Ta from turning on the power switch 671 to releasing the reset signal is set to 100 ms, for example. To generate the RAM clear signal, the power switch 671 is turned on while the RAM clear switch 676 is depressed. The control board CPUs 611 and 621 monitor the presence or absence of a RAM clear signal at the input ports 613 and 623 via the data bus.

  FIG. 6 shows the operating state of each part of the power supply board 85 and the main control board 80 when the power supply switch 671 is turned on while the RAM clear switch 676 is depressed and power supply is started from the power supply board 85.

  The reset signal is released after the elapse of time Ta from when the power switch 671 is turned on (when the power is turned on). When this reset signal release becomes valid, the main control board CPU 611 starts a security check. Although not shown, the CPU 621 of the payout control board also performs a security check when the reset signal release becomes valid. The security check time T1 is 185 ms in the main control board CPU611 in this specific example although it depends on the CPU type, system clock frequency, and the like. As is well known, the security check is to check whether or not the content of the ROM in which the CPU 611, 621, etc., which are one-chip microcomputers, has written the progress of the game, is normal.

  In the pachinko machine 50, the security check time T1 of the main control board CPU611 takes longer than the time required for the security check of the payout control board CPU621. Therefore, when the security check of the main control board CPU 611 is completed, the payout control board CPU621 completes the security check, and when the main control board CPU611 starts the control of the game according to the program written in the ROM, the payout control board CPU621 is already set. The game control is executed. As a result, even if the main control board CPU 611 transmits data to the payout control board CPU 621 immediately after the power is turned on, the payout control board CPU 621 finishes the security check and executes its own control, so that the data can be reliably received. Can do.

  On the other hand, since the power switch 671 is turned on while the RAM clear switch 676 is being pressed, the RAM clear signal is output for a predetermined time from the time when the reset signal is released. This “predetermined time” is the time until the operator depresses the RAM clear switch 676 (generally realized by releasing the hand from the RAM clear switch 676). In general, it is considered that the time from when the operator turns on the power switch 671 until the operator clears the RAM clear switch 676 is sufficiently longer than the time required for the security check of the main control board CPU 611. In order to clear the RAM, the operator needs to press the RAM clear switch 676 again. Along with this, the RAM clear signal is generated again, and as a result, the RAM clear signal draws two pulse waveforms as shown in the lowermost stage of FIG.

  Further, as shown in FIG. 7, the power switch 671 and the RAM clear switch 676 are both fixed to one surface of the power substrate 85, and the power substrate 85 is made of resin from the fixed surface side of the switches 671 and 676. It is covered with a molded box-shaped cover. The power switch 671 and the RAM clear switch 676 are exposed from the cover and arranged close to each other. Therefore, both switches 671 and 676 can be operated simultaneously with one hand without removing the cover.

  Processing executed by the CPU 611 of the main control board 80 when the power is turned on will be described with reference to FIG. When the power switch 671 is operated, the pachinko machine 50 is energized, the reset signal is released, and when the security check of the CPU 611 itself is completed, this process is started and an initial process of turning on the power is executed (S5). Then, it is determined whether or not the RAM clear signal is on (S10). As described above, since the RAM clear signal is H (on) if the RAM clear switch 676 is in the on state when the reset signal is released, this is substantially the RAM clear switch 676 in the on state when the power is turned on. It is determined whether or not it was.

  When the RAM clear signal is not on (S10: no), the pachinko machine 50 is restored to the state when the power is turned off. Therefore, first, it is determined whether or not the occurrence information at the time of power-off is normal (S15). If normal (S15: yes), the RAM determination value is calculated (S20), and whether or not the determination value is normal. Is determined (S25). Here, the determination value of the RAM is a value stored in the RAM when the power is turned off. In S25, it is determined whether or not the value calculated in S20 matches the value stored in the RAM. If the determination value is normal, that is, if the determination value matches the stored value (S25: yes), the process at the time of power recovery (for example, the information generated when the power is turned off is cleared or the sub integrated control device 83 is A command for returning to the gaming state when the power is cut off is transmitted) (S30). Then, interrupt setting is performed (S35), and the process proceeds to the main routine.

  When the RAM clear signal is on (S10: yes), the pachinko machine 50 is returned to the initial state. For this purpose, first, it waits for the RAM clear signal to turn off in the infinite loop of S40 in FIG. When it is turned off, the RAM clear reservation flag is set to 1 (S45), and RAM clear reservation notification processing is performed (S50). The RAM clear reservation notifying process is a process of turning on the LED lamp 618 (see FIG. 5) of the main control board 80, and this LED lamp 618 is provided at a position that can be visually recognized by the operator. When the RAM clear reservation notification process is completed, a hard random number value is acquired and stored in the random number value register 1 in S55. Here, the hard random number is a random value generated by a random number circuit 616 (see FIG. 5) included in the CPU 611 of the main control board 80. The random number circuit 616 is activated almost simultaneously with the energization of the CPU 611 (see also FIG. 6), and the value of 0 to 65535 is set to a certain rule (for example, 0 → 1 → 2 →. Update by 0 → ...) and generate. Note that the period for one round of the random number value is about 50 ms.

  An outline of the random number circuit 616 is shown in FIG. The random number circuit 616 includes a random number generation circuit 100 therein, which is activated substantially simultaneously with the energization of the pachinko machine 50 (more specifically, the CPU 611), and receives a system clock signal from a clock circuit provided on the main control board 80. The random number value is updated at a timing obtained by appropriately dividing (SCLK). The random number circuit 616 includes random number registers 101 to 103, and the hard random number generated by the random number generation circuit 100 is stored in any one of these random value registers 101 to 103. The register to be stored is designated by setting a value corresponding to the random value fetch register 104 in advance. Specifically, if it is desired to store a random value in the random value register 1, set 1 in the random value fetch register 104, and if it wants to store in the random value register 2, set 2 in the random value fetch register 104. If it is desired to store the value in the numerical value register 3, 3 is set in the random number fetch register 104. The process of S55 waits for the random number generation circuit 100 to generate a random value and store the random value in the random value register 1 after setting 1 in the random value fetch register 104. Note that the random value latch flag register 105 indicates whether or not a random number value has been captured in each of the random value registers 101 to 103. When a random value is captured in the random value registers 101 to 103, a corresponding flag is displayed. Is set to 1. Therefore, by referring to the random value latch flag register 105, it is possible to know which random value register is in use (stores the random value). This flag is reset to 0 when the stored random number value is read.

  Returning to FIG. When the hard random number value is stored in the random value register 1 in S55, it is again determined whether or not the RAM clear signal is on (S60). This means waiting for the RAM clear switch 676 to be pressed again. When the RAM clear signal is not on (S60: no), the process proceeds to S65 and waits for 10s until the RAM clear signal is turned on. If the RAM clear signal does not turn on after 10 seconds (S65: yes), the RAM clear reservation flag is reset to 0 (S70), and RAM clear reservation notification stop processing is performed (S75). The RAM clear reservation notification stop process is a process of turning off the LED lamp 618 of the main control board 80 that was turned on in S50. When this process is completed, the acquired hard random number is cleared and the process returns to S15 (FIG. 8). Perform state recovery.

  When the RAM clear signal is ON (S60: yes), the RAM clear reservation flag is reset to 0 (S85), and RAM clear reservation notification stop processing is performed (S90). The RAM clear reservation notification stop process is the same process as S75, and turns off the LED lamps lit in S50. When the RAM clear reservation notification stop process is completed, a hard random number value is acquired and stored in the random number value register 2 in S95. All the contents stored in the RAM are cleared to 0 (S100), and initial value random number setting processing is executed (S105). When the initial value random number setting process is thus completed, the RAM is initialized (S110), an interrupt is set (S115), and the process proceeds to the main routine (see FIG. 8).

The initial value random number setting process is shown in FIG. When this process is started, first, random number values stored in the random number value registers 1 and 2 are read (S300). In the subsequent S305, the initial value α is calculated based on these random values. Specifically, a value obtained by subtracting the random value stored in the random value register 1 from the random value stored in the random value register 2 is calculated (this calculated value is referred to as a random difference), and this Let α be the remainder obtained by dividing the random number difference by the maximum value +1 of the big hit determination random number. In the pachinko machine 50, the maximum value of the random number for determining the big hit is 349 (described later), and in S305, the random number difference is divided by 349 + 1, that is, 350. For example, if the hard random number acquired in S55 is 35000 and the hard random number acquired in S95 is 62000, the random number difference is 27000. If this is divided by 350, the quotient is 77 and the remainder is 50, so α = 50. When the random number difference becomes negative, the maximum value +1 of the jackpot determination random number is repeatedly added to the random number difference until the random number difference becomes positive.
The random number difference corresponds to the time (hereinafter referred to as operation time) from when the operator releases the RAM clear switch 676 until the operator presses the RAM clear switch 676 again. Although the value of α may change due to a change in the operation clock of the CPU 611 due to a temperature change or the like, the variation in the operation time is overwhelmingly large, so the operation time becomes dominant. As described above, the value α set as the initial value of the soft random number in the initial value random number setting process can be expected to be different every time. In S310, this α is set as the initial value of the soft random number, and the process ends (returns to the process of FIG. 9).

  The main routine will be described with reference to FIG. Although the main routine is shown in FIG. 8 as if it is a process that is executed after the power-on process, the main routine actually executes the process up to S35 and then about every 2 ms. It is executed periodically by a hard interrupt. In the present embodiment, the process that is executed only once from S200 to S255 is referred to as “main process”, and the process of S260 that is repeatedly executed as long as time is allowed within the remaining time after executing this main process. This is referred to as “residual processing”. The “main process” is periodically executed by the interrupt.

  When a hardware interrupt is executed by the microcomputer, it is first determined whether the interrupt is a normal interrupt (S200). This determination process is performed by determining whether or not the value of a predetermined area of the RAM as a memory is a predetermined value. When the process executed by the microcomputer shifts to this process, the normal process is executed. It is for judging whether it is okay. If the interrupt is not normal, microcomputer runaway due to noise or the like may be considered when power is turned on. However, microcomputer runaway may be considered to be almost impossible due to recent technological improvements, and is usually when power is turned on. When the power is turned on, the value of the predetermined area of the RAM is different from the predetermined value.

  When it is determined that the interrupt is not normal (S200: no), initial setting (for example, writing a predetermined value to the predetermined area of the memory and setting a special symbol and a normal symbol as an initial symbol to each initial to the working area of the memory. Value is written (S205), and the process proceeds to the remaining process (S260).

  If a positive determination is made that the interrupt is normal (S200: yes), an initial value random number update process is executed (S210). This process is an increment process that increments the initial random number value by 1 each time this process is executed. The initial random number value before this process is incremented by +1, but the random number value before this process is executed is the maximum. When the value is “349”, it returns to the initial value “0” in the next processing, and 350 integers from “0” to “349” are repeatedly generated in ascending order.

  The big hit determination random number update process (S215) following S210 is an increment process that increments by one each time the process is executed, as in the initial value random number update process. When the maximum value is "349", the next process starts with the next process. Then, 350 integers from “0” to “349” are repeatedly generated in ascending order. The initial value of the jackpot determination random number is the value set in the initial value random number setting process. In the above example, since α = 250, the big hit determination random number is updated as “250” “251” “252”... “349” “0” “1”.

When the big hit determination random number is updated once (350 times), the initial value random number at that time is set as the initial value of the big hit determination random number, and the big hit determination random number is +1 from the initial value. Increment processing is performed. Then, when the big hit determining random number makes one round again, the initial value random number at that time is changed to the initial value of the big hit determining random number. That is, this series of operations is repeated. In the above example, when the big hit determination random number reaches “249”, it is one round, so the next value after “249” is the value of the initial value random number. If the value of the initial random number is “87”, it changes to “249” “87” “88”... “349” “0” “1”. Next to is a new initial random number value.
The jackpot symbol determination random number update process (S220) is configured as a counter that repeatedly creates ten integers “0” to “9”, and is incremented by +1 for each process and is the initial value “0”. Return to.

  The hit determination random number update process (S225) subsequent to S220 is configured as a counter that repeatedly creates six integers “0” to “5”, and is incremented by +1 for each process and the initial value is exceeded. Return to a certain “0”. The number of values to be won is 3 in both the normal probability state and the high probability state, and the values are “0”, “3”, and “5”. This winning determination random number update process is used for lottery of normal symbols, and other initial value random numbers, big hit determination random numbers, big hit symbol determination random numbers, reach determination random numbers, and fluctuation pattern determination random numbers are drawn special symbols. Used for.

  The reach determination random number update process (S230) is configured as a counter that repeatedly generates 229 integers from “0” to “228”, and is incremented by +1 for each process and the initial value “0” is exceeded. Return to. In the normal probability state, the number of values won when the variable time shortening function is not activated is 21, and the values are “0” to “20”. The number is 5, the values are “0” to “4”, the number of values to be won in the high probability state is 6, and the values are “0” to “5”.

  The variation pattern determination random number update process (S235) is configured as a counter that repeatedly creates 1021 integers from “0” to “1020”, and is incremented by 1 for each process and is the first value when the maximum value is exceeded. Return to "0". Note that the big hit determination random number, the big hit symbol determination random number, the hit determination random number, the reach determination random number, and the variation pattern determination random number are called soft random numbers with respect to the hard random numbers described above (see also FIG. 6).

In the subsequent winning confirmation process (S240), confirmation of winning of the first start port 11 and second start port 12 and input processing of each switch provided in the pachinko machine 50 and connected to the main control board 80 are executed.
In this embodiment, when the game ball wins the first start port 11 and the second start port 12, a plurality of random numbers such as a big hit determination random number, a big hit symbol determination random number, a variation pattern determination random number, a reach determination random number, etc. are acquired. However, the number that can be reserved is limited to 4 each of the first start port 11 and the second start port 12, and when the first reserved memory is full, the game ball is stored in the first start port 11. Even if the winning ball or the second hold memory is full, even if the game ball wins the second start port 12, only the winning ball is paid out, and the plurality of random numbers are not stored. Yes.

  Subsequently, a success / failure determination process (S245) as condition establishment determination means for determining whether or not a big hit is made. When this success / failure determination process (S245) ends, each output process (S250) such as an image output process is subsequently executed.

  In each output process (S250), as the game progresses, the main control board 80 controls the production symbol control device 82, the payout control board 81, the launch control device 84, the sub integrated control device 83, the big prize opening solenoid 14b, and the like. Each output process is executed. That is, when it is detected by the winning confirmation processing (S240) that there is a winning game ball in each winning slot on the game board 1, the winning ball data is output to the payout control board 81 so as to pay out the gaming ball as the winning ball. In the process of outputting sound data corresponding to the gaming state to the sub-integrated control device 83, an error signal is output to the production symbol control device 82 to notify that there is an error when the pachinko machine 50 is abnormal. Each process is executed.

  In the subsequent fraud monitoring process (S255), it is monitored whether or not fraud is performed on the normal winning award (the first left winning port 31, the second left winning port 32, the first right winning port 33, the second right winning port 34). It is a process to determine whether or not the number of game balls entering the winning opening within a predetermined time is greater than a predetermined number. It is processing to do. That is, the fraud determination means is provided on the main control board 80.

  The above-described remaining process subsequent to this process is composed of the initial value random number update process (S260), but is exactly the same process as S210 described above. This process forms an infinite loop and is repeated as long as time is allowed until the next interrupt is executed. The time required for executing this processing from S200 to S255 described above differs for each interrupt depending on whether or not to execute the jackpot processing, the difference in the display mode of special symbols, and the like. As a result, the number of times the remaining process is executed is different for each interrupt, and the value updated to the initial random number is not uniform when the interrupt process shown in FIG. 9 is executed once. Thereby, the possibility that the initial value random number is synchronized with the big hit determination random number becomes extremely small. If the value of the initial value random number (350 patterns from 0 to 349) when the big hit determination random number has made one round, the probability of synchronization is only 1/350. The hit determination random number update process (S225) described above may also be executed in the remaining process.

  According to the pachinko machine 50 configured as described above, when the power switch 671 is turned on while pressing the RAM clear switch 676, the hard random number value when the RAM clear switch 676 is stopped and the RAM clear switch again. Based on the difference from the hard random value when 676 is pressed, the initial value of the jackpot determination random number is determined. Since the time from when the operator stops pressing the RAM clear switch 676 to when it is pressed again is different each time, the difference between the hard random numbers is hardly the same as before. It can be expected that the remainder obtained by dividing this difference by the maximum value +1 of the jackpot determination random number is different every time the RAM clear operation is performed. Therefore, an illegal act of aiming for a big hit by performing a RAM clear operation becomes extremely difficult.

  Hard random numbers are updated at a very high speed of 0 to 65535 in 50 ms, so even if the operator has a habit of releasing the RAM clear switch 676 and immediately pressing it again, two The difference between the random numbers of the two is almost the same as before. Note that if the operator releases his hand from the RAM clear switch 676 prior to turning on the power switch 671, it will be judged as no in S10 and the recovery operation of the pachinko machine 50 will start, so use RAM clear. There is no worry that the cheating done. If the RAM clear is essential, the energization of the pachinko machine 50 is cut off again (for example, the power switch 671 is turned off), and the RAM clear operation is performed.

If the operator forgets to operate the RAM clear switch 676 for the second time, the processing for clearing the RAM is invalidated 10 seconds after the hand is released from the RAM clear switch 676, and the gaming state when the power is cut off is set. Restore. As a result, the gaming machine does not fall into a state where the RAM cannot be cleared or restored.
Further, this specification can be used to cancel the RAM clear in the middle. That is, when the RAM clear switch 676 is inadvertently energized despite the state that the RAM should not be cleared, the RAM clear switch 676 is stopped and 10s passes. Just wait. If it does so, RAM state will not be performed, but the gaming state at the time of a power failure will be restored.

  If the determination in S40 is affirmative, that is, if it is determined that the hand has been released from the RAM clear switch 676 that was being pressed during energization, the LED lamp 618 is turned on by the RAM clear reservation notification process in S50. The operator can confirm that the LED lamp has been turned on and then press the RAM clear switch 676 for the second time to reliably clear the RAM. Further, when the RAM clear operation fails, the LED lamp 618 is not turned on, so that it is understood that the RAM clear operation has failed.

  Note that when the RAM clear is executed, the LED lamp 618 is turned off by the RAM clear reservation notification stop process in S90, so the operator confirms the RAM clear from the previous LED lamp 618 being turned on and off. Can do. When the RAM clear switch 676 is stopped from being pressed for the second time, the LED lamp 618 is turned off by the RAM clear reservation notification stop process in S75, so that the operator confirms that the RAM clear has been successfully canceled. be able to.

  Here, the correspondence between the configuration of the present embodiment and the configuration requirements of the present invention is shown. The processing of S210 to S215 corresponds to the “first random number generation means” of the present invention, the processing of S245 corresponds to the “control means” of the present invention, and the RAM clear switch 676 corresponds to the “clear switch” of the present invention. , S10 corresponds to “first operation determination means” of the present invention, S40 corresponds to “first non-operation determination means” of the present invention, and S60 corresponds to “second operation determination means” of the present invention. The random number generation circuit 616 corresponds to the “second random number generation means” of the present invention, the process of S105 corresponds to the “first initial value setting means” of the present invention, and an affirmative determination is made in S65. The process from S70 to S30 corresponds to the “recovery means” of the present invention, and the process of S50 corresponds to the “notification means” of the present invention. The value stored in the random value register 1 corresponds to the “first variable value”, and the value stored in the random value register 2 corresponds to the “second variable value”.

[Example 2]
A second embodiment of the present invention will be described. Since this embodiment has much in common with the first embodiment, only different points will be described mainly. FIG. 13 shows a part of the processing executed when the gaming machine of the second embodiment is turned on. This figure corresponds to FIG. 9 of the first embodiment. The biggest difference from the first embodiment is that the hard random number is stored in the random value register 1 when the RAM clear switch 676 is pressed for the second time (S445), and the hand is released from the RAM clear switch 676. This is the point when it is done (S455). Although not specified in this figure, the value set as the initial value of the jackpot determination random number is calculated in the same manner as in the first embodiment, based on the hard random value stored in each register. To do.
Since the difference between the value of the hard random number when the RAM clear switch 676 is pressed again and the value of the hard random number when the RAM clear switch 676 is stopped is considered to be different each time, the RAM clear operation is performed. This makes it extremely difficult to cheat on the jackpot.
In the second embodiment, the process of S465 corresponds to the “second initial value setting means” of the present invention, the value stored in the random value register 1 corresponds to the “third variable value”, and the random value register 2 stores The stored value corresponds to the “fourth variable value”.

[Example 3]
A third embodiment of the present invention will be described. Since this embodiment also has much in common with the first embodiment, only different points will be described mainly. FIG. 14 and FIG. 15 show a part of the processing executed when the gaming machine of the third embodiment is turned on. Both figures correspond to FIG. 9 of the first embodiment. The main difference from the first embodiment is that a hard random number is also stored in the random value register 3 when the hand is released from the RAM clear switch 676 pressed for the second time (S565). It is. Then, the initial value random number is set using the values of the three hard random numbers stored in the random number registers 1 to 3 (S575 in FIG. 15). Specifically, the sum of the values of the three hard random numbers and the remainder obtained by dividing this by the maximum value of the big hit determination random number + 1, that is, 350 is α. When the sum of the three hard random numbers overflows, only the portion that fits in 2 bytes is valid and α is calculated. Of course, α may be calculated by other methods. For example, α may be calculated using the product of three hard random numbers instead of the sum of three hard random numbers, or α may be calculated without using the value of the hard random number stored in the random number register 2. May be.
Note that the process of turning off the LED lamp 618 that was turned on in S510 is immediately before the process of storing the hard random number in the random value register 2 (S555), but the hard random number is stored in another position (for example, the random number register 3). May be stored immediately before (S565).

[Other embodiments]
The calculation of α from the random number values stored in the random number registers 1 and 2 may be performed by a method other than the calculation performed in S305. For example, a table in which a value in the random number registers 1 and 2 is associated with a numerical value to be set as an initial value of the first random number corresponding thereto is prepared in advance, and the first random number is referred to by referring to this table. The initial value may be set. However, in this case, it is necessary to prepare as many table data as the initial random number (350 in the above-described embodiment), and the capacity of the ROM or the like for storing the table may be reduced. There is. In this regard, in the above embodiment, since the remainder when the value of the hard random number is divided by the maximum value +1 of the jackpot determination random number is calculated, the storage capacity can be reduced. When this calculation is performed, α may be actually divided by the maximum value of the jackpot determination random number + 1, but the maximum value of the jackpot determination random number + 1 is repeatedly subtracted from the hard random number value to obtain the calculated value. If becomes negative, it may be calculated by adding the maximum value +1 of the jackpot determination random number.
Although the RAM 615 of the CPU 611 and the RAM 625 of the CPU 621 are cleared to 0 by the RAM clear, the non-volatile RAM (for example, the main control board 80, but the non-volatile provided outside the CPU 611) is provided elsewhere. The storage contents of a storage medium other than the RAM or a non-volatile RAM provided on another board (not shown) such as the payout control board 81 may be cleared. In addition, in order to clear the stored contents of the RAM (not limited to the RAM 625) of the payout control board 81, the RAM clear signal may be used as a trigger, or a command for clearing from the CPU 611 of the main control board 80 may be issued. It may be transmitted to the control board 81 and cleared upon receipt of this command.

The reset signal is directly input to the main control board 80 and the payout control board 81 from the reset signal generation circuit 674. However, the reset signal may be input to both or one via a predetermined delay circuit. For example, in the pachinko machine 50, since the time required for the security check is longer for the main control board CPU611 than the payout control board CPU621, no delay circuit is required, but the payout control board CPU621 is used for the security check. If a long time is required, the reset signal is input to the main control board CPU 611 via an appropriate delay circuit, so that the activated main control board CPU 611 can immediately send data to the payout control board CPU 621. The payout control board CPU 621 can finish the security check.
In the above embodiments, the signals are configured as high active. However, some (or all) signals may be configured as low active. For example, the RAM clear signal may be set to low active, and the time when the RAM clear is performed may be performed after the rise of the RAM clear signal.

In the above embodiment, the RAM clear signal is determined based on whether the RAM clear switch 676 is turned on when the power switch 671 is turned on and whether the RAM clear switch 676 is turned off. However, the determination may be made using different signals. For example, the RAM clear signal is generated by the RAM clear signal generation circuit 677 if the RAM clear switch 676 is turned on when the reset signal is released, as described above. Separately, the RAM clear signal is high. In this state, when the RAM clear switch 676 is turned off, a predetermined signal may be generated. When the CPU 611 detects this signal, all of the RAM may be cleared to 0 to obtain a hard random number.
In the above-described embodiment, the power switch 671 and the RAM clear switch 676 are provided on the power supply board 85. However, both or one of them may be provided at another location (for example, the main control board 80 or the payout control board 81). Good. In any of the above embodiments, the lit LED lamp 618 is turned off before the RAM is actually cleared (S100 in the first embodiment), but may be turned off after the RAM is cleared.
