Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine, and more particularly to a gaming machine that includes a main control board that controls the progress of the game and a sub-control board other than the main control board.
[0002]
[Prior art]
A gaming machine, such as a pachinko gaming machine, is configured to pay out a predetermined number of gaming balls as prize balls when the launched gaming balls win a prize opening. The game balls won in each winning opening on the game board surface are temporarily stopped in the safe ball tank, and the stopped game balls are detected one by one by a sensor, and a predetermined number of prize balls are driven by a motor or the like. After paying out to the player by the device, the detected game ball is discharged from the safe ball tank.
In this conventional pachinko machine, the winning game balls are stopped in the safe ball tank, and the prize balls are discharged out of the machine after paying out the prize balls, so that even if an unexpected situation such as a power failure occurs, the winning game balls are safe Since it was stopped in the ball tank, it had the effect of not giving a disadvantage to the player.
[0003]
[Problems to be solved by the invention]
However, the conventional pachinko gaming machine has the following problems.
(1) Ri consists that there is a need to provide a safe ball tank cassava, becomes complicated.
(2) When a power outage or the like occurs, the data on the number of premium balls to be paid out disappears, so the maximum number of premium balls is paid out, and the correct premium ball is not paid out. For example, even if 5 or 10 premium balls are to be paid out for one winning ball, 15 premium balls are paid out.
(3) Also, if a power failure occurs in a state that is advantageous to the player, such as during jackpot processing, high probability, or during short-time games, the game will start from the initial state when the power failure is restored, so there is an unexpected disadvantage to the player May be given.
[0004]
In order to solve these problems, in recent years, a prize payout control board for paying out a prize ball is provided, and data corresponding to the number of prizes to be paid out is stored in a memory of the prize payout board, and this memory is backed up by a battery. Proposals have been made.
As the invention related to the proposal, the applicant of the present invention has made an invention shown in “Ball Ball Game Machine” of Japanese Patent Application No. 10-126693.
This proposal has the excellent effect that the mechanism of the pachinko machine can be simplified and an accurate prize ball can be paid out.
On the other hand, the main control board that controls the progress of the game is also backed up by a battery, so that predetermined data relating to the game state is not lost at the time of a power failure, and a proposal to continue from the game state before the power failure at the time of power failure recovery has been made.
In addition, the time for storing and holding by the battery backup described above is normally configured to be about 1 to 3 hours. This is to cope with only an unexpected power failure (including momentary power failure). Therefore, when the power is shut off when the store is closed and the power is turned on the next day, most of the data stored in the RAM changes. When detecting this data change, the microcomputer is generally configured to execute a game from the initial state of the game.
[0005]
Nevertheless, in such a conventional pachinko game machine described above, grace, considered the following problems.
(1) The prize payout control board stores the prize data before the power failure, but the contents of the prize data are changed due to a runaway microcomputer or electrical noise, or the contents of the prize data are rewritten due to an illegal act. There is also a fear. When only the predetermined data changes when such a state occurs, the issue that paying out prizes according to the stored prize data cannot guarantee the fairness of the game,
(2) Further, even with the main control board, there is a possibility that the gaming state changes due to a microcomputer runaway or the gaming state may be rewritten due to an illegal act. The issue that the fairness of the game cannot be expected even when such a situation occurs,
(3) Furthermore, the normal battery backup time is designed to be about 1 to 3 hours, and when the power is turned on before the pachinko hall is opened, the game can be started from the initial state of the game. However, it is also conceivable that the gaming state when the power is cut off the night before for some reason is stored. In such a case, aside from the will of the pachinko hall side, if there is a gaming machine in which the game continues from the gaming state of the previous day, the issue that the fairness of the game cannot be expected,
Was considered.
The gaming machine of the present invention is made for the purpose of suitably solving these problems and providing a more sound gaming machine.

The judgment result is stored, and when the power is turned on, the memory is referred to, and when the touch switch is in the off state and the firing stop switch is in the on state in the judgment result, the process is executed from the initial state. It is characterized by doing.
[0012]
In general, the power supply from the power supply means can be stopped when the power is shut off when the store is closed, or when a power failure occurs during a game. When a power outage occurs during a game, it is most likely either when the player is operating the firing handle or when the player is not operating the firing handle during a break. When the player is not operating the firing handle during a break, the firing stop switch is not operated. The invention of claim 1 pays attention to this, and if the power is shut off when the player does not touch the launch handle and the launch stop switch is operated, the power is intentionally shut off. Can be considered.
[0013]

[0037]
With the above-described configuration, each CPU operation or control operation of the main control board 30 when the power is supplied to the pachinko machine 10 and the sub-control boards other than the main control board such as the payout control board 31 and the symbol control board 32b Will be described with reference to the timing chart shown in FIG.
When the pachinko machine 10 is powered on, the power board 55 generates DC 32V, DC 12V, and DC 5V, which is a battery backup power source (VBB). Each generated power is supplied to each control board, but the sub-control board such as the payout control board 31 and the main control board 30 operate as follows by the action of the reset 1 circuit 60 and the reset 2 circuit 61. Start up processing.
[0038]
As shown in FIG. 11, when the power is turned on to the power supply board 55 (point P1), the voltage of the DC12V power supply gradually rises from 0V to 12V while drawing a parabola. When the voltage of the DC12V power supply that gradually rises to the reference value LV2 (7.20 to 7.75 V in this specific example), the reset signal 2 that is the output signal of the reset 2 circuit 60 changes from the low level to the high level. Thereby, the reset of each CPU of the sub control board is released, and the CPU 65 of the payout control board 31 starts a security check operation (point P2). At this time, in this specific example, each sub control board such as the symbol control board 32b excluding the payout control board 31 is configured to execute the original control without executing the security check operation.
When the power supply voltage of DC12V is the reference value LV2, the reset signal 1 that is the output signal of the reset 1 circuit 60 is still in the low level state. Therefore, the CPU 64 of the main control board 30 has not been started up yet.
[0039]
When the power supply voltage of DC12V rises from the reference value LV2 to the reference value LV1 (in this specific example, 9.39 to 10.21V), the reset signal 1 of the reset 1 circuit 60 changes from the low level to the high level. Thereby, the reset of the CPU 64 of the main control board 30 is released, and the CPU 64 starts a security check operation (point P3).
The security check time T1 of the CPU 64 of the main control board 30 is designed to be equal to or longer than the security check time T2 of the CPU 65 of the payout control board 31.
As is well known, the security check is a function in which the CPUs 63 and 64, which are one-chip microcomputers, check whether or not the content of the ROM into which the game progress is written is normal.
[0040]
The security check time T1 of the main control board 30 is longer than the security check time T2 of the payout control board 31, and the reset release time of the CPU 64 of the main control board 30 is later than the reset release time of the CPU of each sub control board (point P4). And P5) . Thereby, when the CPU 64 of the main control board 30 starts executing the game control according to the program written in the ROM, each sub-control board has already executed the game control. As a result, even if the CPU 64 of the main control board 30 transmits data to each sub-control board immediately after the power is turned on, each sub-control board is executing the original control, so that the data can be reliably received. .
In this specific example, the security check time T1 is about 439 ms, and the time from when the CPU 64 of the main control board 30 turns on the power to the game control is about 529 ms to 549 ms. Further, the security check time T2 is about 200 ms, and the time from when the CPU 65 of the payout control board 31 which is one of the sub-control boards is turned on to control the game is about 202 ms to 203 ms.
[0041]
Next, the operation when the power supply to the pachinko gaming machine 10 is cut off will be described according to the timing chart shown in FIG.
When the power supply to the pachinko gaming machine 10 is cut off (point P6), the power supply voltage of DC12V generated by the power supply board 55 decreases substantially immediately after the cut off, but then decreases linearly after a predetermined time. 0V. When the reference voltage LV4 (10.25 to 10.70 V in this specific example) is reached (point P7) in the course of gradually decreasing linearly, the backup signal 1 of the backup 1 voltage monitoring circuit 62 of the power supply board 55 is , Changes from high level to low level. As a result, the forced interrupt terminal NMI of the CPU 64 of the main control board 30 becomes low level, and a non-maskable interrupt is applied to the CPU 64. At this time, the CPU 64 can save data indicating the current game progress, and thereafter prohibit access to the RAM.
[0042]
When the voltage of the power supply voltage DC12V decreases from the reference voltage LV4 to the reference voltage LV1 (point P8), the reset signal 1 of the reset 1 circuit 60 of the power supply substrate 55 changes from the high level to the low level. As a result, the CPU 64 is reset. Thereafter, the power supply voltage of DC12V gradually decreases with the passage of time and reaches the reference voltage LV4 (8.00 to 9.23V in this specific example) (point P9), and the output signal of the backup 2 voltage monitoring circuit 63 2 changes from a high level to a low level. As a result, the NMI terminal of the CPU 65 of the payout control board 31 becomes a low level, and a non-maskable interrupt is applied to the CPU 65. At this time, the CPU 65 can save data indicating the current prize ball payout state and the ball lending payout state, and thereafter prohibit access to the RAM.
[0043]
When the power supply voltage of DC12V further decreases from the reference voltage LV3 to the reference voltage LV2 (point P10), the reset signal 2 that is the output signal of the reset 2 circuit 61 changes from the high level to the low level. As a result, the CPU 65 and the CPU 66 are reset, and the operations of the other sub-control boards are stopped.
Here, as described above, the RAM of each of the main control board 30 and the payout control board 31 is backed up by the battery, and the data stored in the RAM is stored for a predetermined time (about 1 hour 20 in this embodiment) even when the power is turned off. Minutes to about 3 hours 30 minutes).
[0044]
As described above, when the power is turned off, the CPU 64 of the main control board 30 is first set to the reset state, and then each CPU of the sub control board is set to the reset state. This has an effect that each sub control board receives the data transmitted before the CPU 64 of the main control board 30 is turned off.
[0045]
Next, the operation of this specific example having the above-described configuration will be described when the power is turned on and when the power is turned off. Since the processing from the time when the power is turned on until the power is turned off is the same as the conventional one, the detailed description is omitted. Here, for the sake of convenience, first, the process at the time of power-off will be described according to the flowchart shown in FIG.
The flowchart shown in FIG. 13 is a process executed by the CPU 64 of the main control board 30 and the CPU 65 of the payout control board 31 and executed when the signal at which the forced interrupt terminal NMI of each CPU changes from the high level to the low level falls. Process.
When the processing executed by the CPU 64 and CPU 65 shifts to this routine, first, processing for writing the predetermined value 55H into a plurality of predetermined areas of the RAM is performed (step S100). The predetermined value to be written may be any value, but 55H or AAH in which each bit in one byte is alternately “1” and “0” is preferable.
[0046]
After a predetermined value is written in a predetermined area of the RAM, data saving is executed (step S110). This data saving process is performed on the main control board 30 in the current game progress status, for example, whether the probability is high probability, whether it is a big hit, whether the symbol is changing on the special symbol display device. In this process, each piece of data indicating the progress of the game is written in a predetermined area of the RAM. On the other hand, the payout control board 31 is a process of writing each data indicating the payout state of the current number of prize balls and the payout state of the lending balls into a predetermined area of the RAM. This save process need not be configured to execute this process as long as it is an algorithm that always writes the current state to a predetermined area of the RAM. When the data saving is executed, access to the RAM is then prohibited (step S120).
[0047]
This RAM access prohibition process is to improve the accuracy and certainty of data to be saved by prohibiting writing to the RAM when the power supply voltage is unstable.
When access to the RAM is prohibited, a process of waiting for the reset terminal RES to fall to a low level is executed (step S130). Here, when the reset terminal is lowered to a low level within a predetermined time, specifically, when the reset signal 1 output from the reset 1 circuit 60 is lowered to a low level, the CPU 64 stops the operation, and the above-described reset is also performed. When the reset signal 2 output from the two circuit 61 falls to a low level, the CPU 65 stops its operation. On the other hand, when each reset signal does not decrease to a low level within a predetermined time, the power supply voltage temporarily returns to the original voltage just by slightly decreasing without reaching the reference voltage LV3 or LV4. In this case, after the access prohibition process to the RAM is canceled (step S140), the process returns to “return” and the original process is executed.
[0048]
When the power is turned on and the security check is completed, the CPU 64 of the main control board 30 executes a “power-on routine” shown in FIG. This routine is executed only once when the signal at which the reset terminal RES changes from low level to high level.
When the process moves to this routine, it is determined whether or not the power failure is restored (step S150). In this specific example, as described above, the DC5V backup power supply is configured to store and hold the data stored in the RAM of the CPU 64 and CPU 65 for about 1 hour 20 minutes to about 3 hours 30 minutes by the capacitor. For this reason, the data in RAM is stored and retained in the normal state (intentional power outage) in which the power is turned off and the power is turned on the next morning after the business is closed ( when the store is closed) instead of a general power outage including instantaneous power failure. It has not been. As a result, the predetermined value written in the predetermined area of the RAM at the time of intentional power failure (resulting from the interruption of the power supply after the end of business) is different from the predetermined value without being stored and held. . On the other hand, a general power failure including a momentary power outage is restored after one hour. At the time of such a power failure, the predetermined value written in the predetermined area of the RAM is stored and held without changing. Therefore, by comparing the values written in the predetermined area of the RAM, it is determined whether or not the power failure is restored.
[0049]
If it is determined in step S150 that the power failure is not restored, an initial setting (step S160) such as clearing the memory value is executed, and an affirmative determination is made when the power failure is restored. Then, the recovery process (step S170) is executed and the process returns.
In the recovery process, the CPU 64 of the main control board 30 executes preparations for executing the normal process from the data indicating the progress of the saved game, and sends a command code notifying each sub-control board that the power has been recovered from the power failure. To do. The symbol control board 32b that has received this command code performs a process of displaying messages such as “execution of power failure recovery processing” and “continuing from the game content before the power failure” on the screen of the LCD 32a. Or the sound control board | substrate 35 alert | reports that there was a power failure by an audio | voice.
Thereafter, the CPU 64 periodically executes a known “main routine” shown in FIG. 15 by a hardware interrupt every 2 ms.
That is, this main routine is composed of the main process and the residual process. Although details are omitted, it is determined whether or not the interrupt is normal (S200), initial setting (S210), random number update process (S220), and each input process (S230). The determination process (S240), the image output process (S250), each output process (S260), and the off symbol random number update process (S270) are executed.
As a result, when a power failure occurs, the CPU 64 of the main control board 30 can continue to control the game from the progress state of the game before the power failure, and does not give the player an unexpected disadvantage or discomfort.
[0050]
On the other hand, when the power supply is turned on and the security check is completed, the CPU 65 of the payout control board 31 executes a “main routine” shown in FIG.
In this routine, whether or not the power failure is restored is determined by the same processing as the processing in step S150 described above (step S300). If an affirmative determination is made that the power failure is restored, the ball is stored based on the stored data. The cutting motor 31c is driven and controlled to perform payout of award balls (step S310), and the ball lending motor 31d is driven and controlled to execute lending of balls (step S320). Thus, if there is unpaid prize ball data at the time of the power failure, the prize balls are paid out based on the data stored and retained after the restoration of the power failure. Similarly, if there is unpaid ball lending data when a power failure occurs, the ball lending is paid out based on the data stored and retained after the power failure is restored. Thereby, even if a power failure occurs, there is no disadvantage to the player.
If it is determined in step S300 that the power failure is not restored, a normal process is executed after the initial setting (step S330).
[0051]
As described above, according to the specific example described in detail, the sub control board 31 and the main control board 30 including the payout control board 31 and the symbol control board 32b are reset by one power supply board 55 to execute the start-up of the control operation. The control operation is also stopped. As a result, the control can be unified, the reset circuit is not provided on each control board, the number of components can be reduced, and the control timing shift due to component errors. has effect, the effect of improving inspection efficiency can determine the timing of the timing of resetting only the power board 55 in the control board if check of preventing.
Further, in this specific example, since the data is saved before the control operation is stopped by the backup voltage monitoring circuit, there is an effect that the accuracy and certainty of the data stored and held can be ensured.
Further, in this specific example, the power supply board 55 is provided with two reset circuits, and the control operation of the main control board 31 is stopped earlier than the sub control board, and the sub control board is controlled earlier than the main control board 31 when the power is turned on. It is configured to launch operations. As a result, each sub-control board has an excellent effect that it can reliably receive data from the main control board 30 while configuring a one-way communication circuit.
[0052]
Further, in this specific example, as shown in FIG. 4, the prize ball payout switch 31 a is connected to the payout control board 31 and the main control board 30. As a result, the main control board 30 can also manage data on the number of prize balls for winning and the number of paid-out prize balls, and send the prize ball data managed on the main control board to the payout control board 31. This makes it possible to make a comparative judgment. Further, when the winning ball data on the payout control board 31 disappears due to any cause, it is possible to pay out the winning balls to the player based on the winning ball data on the main control board.
In this specific example, since the ball removal switch 46 is connected to the main control board 30, a game ball detected by the prize ball payout switch 31 a when the ball removal operation is executed is displayed on the main control board 30. It can be determined that it is not a payout with a prize ball but a ball removal operation. It is also possible to send the ball 抜Su switch 46 is turned from the main control board 30 to the payout control board 31.
[0053]
In this specific example, the power supply board 55 includes the two reset circuits 60 and 61. However, the control board may be reset by a single reset circuit. Alternatively, a forced interruption may be applied to the CPU 64 of the main control board 31 and the CPU 65 of the payout control board 31 by one backup voltage monitoring circuit. In the case of such a configuration, there is also an effect that the reset timing or forced interrupt timing of each control board can be made completely the same.
In this specific example, the prize ball payout switch 31 a is connected to the payout control board 31 and the main control board 30, but may be connected only to the main control board 30. In the case of such a configuration, the configuration may be such that the number of detected prize balls is transmitted from the main control board 30 to the payout control board 31.
[0054]
Next, a second specific example will be described with reference to FIGS.
In the second specific example, the electric circuit shown in FIG. 17 is adopted as the electric circuit shown in FIG. 4 used in the first specific example, and the other configuration is the same as the configuration of the first specific example. It is.
In the second specific example, the touch switch 24 a and the firing stop switch 24 b connected to the launch control board 33 are additionally connected to the main control board 30.
In the second specific example, when the forced interrupt terminal NMI of the CPU 64 of the main control board 30 falls, before executing the “power failure processing routine” shown in FIG. 13 of the first specific example, “ "Intentional power failure detection routine" is executed.
When the process executed by the CPU64 of the main control board 30 is moved to this routine, the touch switches 24a without touching the outgoing morphism handle 24 is off state, is and fired stop switch 24b Gao emission state whether (step S400 to S410). Here, if both are determined to be affirmative, a process of setting the value of the flag FG1 to “1” (step S420) is executed and the process returns to “return”. If a negative determination is made in either step S400 or step S410, the process returns to “return”.
[0055]
If the power is supplied again within a short time within one hour after the power is cut off, the “power-on routine” shown in FIG. 14 executed in the first specific example shown in FIG. A “memory clear routine” is executed.
Here, first, it is determined whether or not the value of the flag FG1 is “1” (step S500). When an affirmative determination is made that the value of the flag FG1 is “1”, the CPU 64 of the main control board 30 executes a process of clearing the area storing the game state in the RAM and returning it to the initial state of the game (step). S510). Specifically, the process of returning the data saved in step S110 of the “power failure processing routine” shown in FIG. 13 of the first specific example, that is, the data indicating the game state to the initial state of the game is executed.
After executing the process of step S510, the CPU 64 of the main control board 30 transmits a memory clear command to the payout control board 31 (step S520). Receiving this command, the CPU 65 of the payout control board 31 executes a process of clearing a predetermined area of the RAM storing each data indicating the payout state of the number of winning balls and the payout state of the lending balls.
After executing the process of step S520, the process of clearing the flag FG1 to zero (step S530) is executed, and the process returns to “return”. On the other hand, when a negative determination is made in step S500, the process returns to “return”.
[0056]
According to a second embodiment, without touching the outgoing morphism handle 24, and when the power is interrupted when the firing stop switch 24b is operated, the flag before stopping the CPU64 operation of the main control board 30 FG1 Is launched. If the flag FG1 is set when the power is turned on again, the main control board 30 executes a process for returning the game state to the initial state, and the payout control board 31 sets the number of winning balls and the number of rented balls to zero. Execute the process to clear. Thereby, the pachinko gaming machine 10 is forcibly returned to the initial state of the game. This is due to the following reason.
In general, as a case where power is not supplied to the pachinko gaming machine 10, there are a case where the power is shut off when the store is closed, a case where a power failure occurs during the game, and the like. When a power failure occurs during a game, it is most likely either when the player is operating the firing handle 24 or when the player is not operating the firing handle 24 during a break. When the player is not operating the firing handle 24 during a break, the firing stop switch 24b is not operated. This in focus, not touch the firing handle 24, and if the firing stop switch 24b is to have power supply is interrupted in Rutoki operation assumes that the clerk of pachinko hall blocked intentionally power, In such a case, if the power is turned on again, a process of returning the pachinko gaming machine 10 to the initial state of the game is executed. As a result, even when the data relating to the state of the game stored and retained in the event of a power outage and the data relating to the number of prize balls change for any reason, it is possible to respond appropriately and improve the fairness of the game It has an excellent effect of being able to. In addition, this specific example also has an effect that the game can be returned to the initial state without providing a special operation switch.
[0057]
Next, a third specific example will be described.
In the third specific example, in the circuit shown in FIG. 4 used in the first specific example, although not shown, a reset switch is connected to the input side of the main control board 30, and the “memory” shown in FIG. The processing of “clear routine 2” is executed, and the other configuration is the same as that of the first specific example.
When the process executed by the CPU64 of the main control board 30 is transferred to the routine First, the reset switch is judged whether or not the lower press Gera (step S600). When the reset switch is made is affirmative judgment that was lower press Gera, executes the process of returning the region of the RAM storing the game state of the game of the initial state of the game (step S610), then the payout control board 31 The process of transmitting the memory clear command to the terminal (step S620) is executed, and the process returns to “return”. On the other hand, when a negative determination is made in step S600, the process returns to “return”.
The payout control board 31 that has received the memory clear command executes a process of clearing the data related to the number of winning balls and the data related to the number of lent balls to zero.
[0058]
In a third embodiment, even without interrupting the power supply, can be returned to the pachinko gaming machine 10 by the lower up Rukoto press the reset switch to the initial state of the game, the same effects as embodiment 2 has It can be demonstrated.
In the third embodiment, when the reset switch is galley lower press may be configured to return only the main control board 30 to the initial state of the game. Alternatively, only the payout control board 31 may be returned to the initial state of the game. When only the payout control board 31 is returned to the initial state of the game, the reset switch may be connected to the payout control board 31.
