Next, in SA4, a display process for outputting command data for image display control from the game control microcomputer 115 to the image display device 58 is executed. Next, a prize ball process for processing a prize ball that has won a prize hole in each of the pachinko gaming machines 1 is executed.

Next, sound processing for generating sound from the speaker 14 is performed by SA6. Next, according to SA7, the image display device 5 is set in accordance with a predetermined process.
8, a process for displaying an image is executed.
Next, in SA8, a random creation process for creating numerical data of a random counter such as a big hit determination random counter for determining whether or not to generate a big hit state is executed. Next, at SA9, the pachinko gaming machine 1
A switch process for performing a process corresponding to a winning ball to various winning ports provided in the game is executed. Next, SA1
The process proceeds to 0, and an error process for performing a predetermined process when an abnormal operation state occurs in the pachinko gaming machine 1 is executed. Next, at SA11, a symbol random update process for updating a symbol counter for symbol determination of symbols variably displayed on the image display device 58 is executed. This symbol random update process is repeatedly executed until there is an interrupt.

In the pachinko gaming machine 1, a power failure interruption process for storing a game state being executed for a predetermined period when power is cut off due to a power failure or a power-off operation is executed. Hereinafter, the processing contents of the interruption processing at the time of power failure will be described. The power failure interruption process is executed by the CPU 115a when the power failure detection circuit 124b detects a power failure state.

FIG. 7 is a flowchart showing the processing contents of the interruption processing at the time of power failure. First, step S (hereinafter simply referred to as S
37), a process of storing data indicating the address of the game control program being executed by the CPU 115a in the RAM 117 is performed. Next, the process proceeds to S38, and it is determined whether or not the timer is counting time. The timer is
This timer is used to determine whether a predetermined period has elapsed since the occurrence of the power failure state. If it is determined in S38 that the timer is not counting, the process proceeds to S40 described below.
On the other hand, when it is determined in S38 that the timer is counting, the process proceeds to S39, and a process of starting counting of the timer is performed. Then, the process proceeds to S40.

In S40, it is determined whether or not the value of the timer has reached a predetermined value. The predetermined value is, for example, 1
It is set to a relatively short time of about 0 to 60 minutes. S
If it is determined by 40 that the value of the timer has reached the predetermined value, the process proceeds to S42 described later. On the other hand, when it is determined that the value of the timer is not the predetermined value, the process proceeds to S41,
Processing for initializing the data stored in the RAM 117 is performed. The content of the process in S41 is based on the RAM of SA2 described above.
The contents are the same as the contents of the initialization processing. Then, S
Proceed to 42.

In S42, it is determined whether or not the power failure state has been recovered based on the power failure detection signal from the power failure detection circuit 124b. In this case, the restoration of the power failure includes the case where the power supply is started by the power-on operation, in addition to the restoration of the actual power failure state. If it is determined in S42 that the power outage state has not been recovered, the process returns to S40, and
The above-described processing is repeatedly executed until the power failure is restored. On the other hand, if it is determined in S42 that the power outage state has been restored, the process proceeds to S43, in which processing of returning the CPU 115a from the address of the game control program being executed stored in S37 is performed.

As described above, when the power supply is cut off due to a power outage or the like, the data of the address of the game control program that was being executed at the time of the power outage is stored, and the time is measured by the timer. If the power supply is restored before the predetermined period elapses as described above, when the power supply is started by the restoration, the game control is restarted from the address of the stored program. On the other hand, if the power supply is not started before the predetermined time elapses, such as after the amusement arcade is closed, after the predetermined time elapses, the game control for the running game stored when the power supply is cut off. The data at the program address is erased. That is, if the power supply is started as in the restoration of the power failure state before the predetermined period elapses after the power supply is cut off, the game control is performed from the game state stored when the power supply was cut off. If the state is not restored before the predetermined period elapses after the power supply is cut off, such as after the game hall is closed, the game state stored when the power supply was cut off Is invalidated, and the game control is started from the initial state when the power supply is restarted.

In this way, a power outage occurs,
When the power outage is restored within a predetermined period, the game control is restarted from the game state at the time of the power outage, so that the player can be compensated for the power outage, and the player is dissatisfied with the game. Can be prevented. As a result, troubles that may occur between the player and the game arcade can be prevented. Furthermore, when the power supply is not restarted within a predetermined period after the power supply is cut off, the storage of the game state is invalidated and the game control is performed from the beginning, so that a so-called morning set is used. The power supply is cut off when the gaming area is set to a game state that is advantageous to the player, the game state is saved with a backup power supply, and the player starts playing the game from the state of the game when the power is turned on such as opening a store It is possible to prevent improper conduct in a game hall that can be performed.

In the interruption process at the time of power failure shown in FIG.
If the power failure state is not restored within a predetermined period, the RAM 11
The data stored in the RAM 117 is invalidated by performing the process of initializing the RAM 11, but the present invention is not limited to this.
The invalidation of the storage data of 7 may be performed by cutting off the supply of the backup power from the backup power supply to the RAM 117 after a predetermined period has elapsed. Even in such a case, as in the case described above, the RAM 117
Can be invalidated after a predetermined period.

As described above, the power from the backup power source
A configuration in which the supply of power to the AM 117 is cut off after a predetermined period is realized as follows. FIG. 8 is a circuit diagram showing a circuit capable of interrupting the supply of power from the backup power supply to the RAM of the game control microcomputer after a predetermined period has elapsed when a power failure state occurs.

Referring to FIG. 8, this circuit includes a power supply circuit 501, a backup power supply 502, and a power failure detection circuit 50.
3. Timer circuit 504, gate circuit 505 and RAM
506 are included. The RAM 506 stores the RA
This corresponds to M117, and stores game state data. The RAM 506 stores the power supply circuit 50 during normal operation.
1 to operate. The backup power supply 502 (for example, a capacitor or a battery) receives supply of power from the power supply circuit 501, and when the power is supplied, charges itself (power storage) and supplies the power to the gate circuit 505 as it is. I do. On the other hand, backup power supply 502 supplies backup power to each of timer circuit 504 and gate circuit 505 when the power supply potential received from power supply circuit 501 falls below a predetermined value. Further, the power failure detection circuit 503 receives the power supply potential of the power supply circuit 501 and supplies a timer circuit start signal for starting the timer circuit 504 to the timer circuit 504 when the potential drops below a predetermined value.

When the power supply from the power supply circuit 501 is cut off due to a power failure or the like, the timer circuit 504 becomes operable based on the power supplied from the backup power supply 502 and receives a timer circuit start signal. In response to this, the timing operation is started. The timer circuit 504 is
When a time is counted up for a predetermined time and the time is up, a time-up signal is supplied to the gate circuit 505. The gate circuit 505 supplies the power supplied from the backup power supply 502 to the RAM 506 when the time-up signal is not supplied from the timer circuit 504, and supplies the power from the backup power supply 502 when the time-up signal is supplied. An operation of cutting off the supply of power to the RAM 506 is performed.

By adopting such a circuit configuration, the power supply from the backup power supply 502 to the RAM 506 is cut off after a predetermined period of time during a power failure, thereby invalidating the data stored in the RAM 506 after a lapse of a predetermined period from the power failure. can do. Therefore, even with such a configuration, it is possible to prevent the above-described fraudulent act called a morning set.

Second Embodiment Next, a second embodiment will be described. In the second embodiment, an example will be described in which game state data indicating a game state when power supply is cut off is stored using a nonvolatile memory such as an EEPROM.

FIG. 9 is a block diagram showing a control circuit for a point control board 91, a game control board 67 of a pachinko gaming machine according to the second embodiment, and peripheral devices connected thereto. In FIG. 9, portions common to FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

The circuit of FIG. 9 differs from the circuit of FIG. 3 in the following points. EEPRO as a game state storage unit for storing game state data when power supply is cut off
M220 is provided on the game control board 67. EE
The PROM 220 sequentially stores game state data during the game control during the game control. Therefore, EEPR
The OM 220 stores the latest game state data.
When the power supply from the power supply circuit 124a to the game control microcomputer 115 is cut off due to a power failure or the like, the EEPROM 220
5 receives backup power from the power supply circuit 124a.
The game state data is stored for a predetermined period of time after the supply of power to the game control microcomputer 115 is cut off.

Next, the CPU 1 of the game control microcomputer 115 of the pachinko gaming machine 1 according to the second embodiment.
The processing content of the main routine of the game control program executed by 15a will be described. FIG.
It is a flowchart which shows the processing content of the main routine of the game control program of the pachinko gaming machine 1 by embodiment.

The processing contents of the flowchart of FIG. 10 have portions common to those of FIG. 6, and therefore, differences from the flowchart of FIG. 6 will be mainly described.

The processing contents of the flowchart of FIG.
The differences are as follows. That is, in FIG. 10, the processing from the setting of the address of the stack pointer in S1 to the execution of the output processing in S5 is different. Specifically, after execution of S1, S
According to 2, it is determined whether or not the game state data is stored in the EEPROM 220. If it is determined in S2 that the game state data is not stored, the process proceeds to S3, where R
A RAM initialization process for initializing the storage data of the AM 117 is executed. Thereafter, the process proceeds to the output process of S5. On the other hand, S
When it is determined that the game state data is stored in the game state data, the game state recovery processing for restarting the game control from the game state when the power supply is cut off, based on the stored game state data, Is executed. Thereafter, the process proceeds to the output processing of S5.

Next, the processing contents of the above-described RAM initialization processing in S3 will be described. The processing contents of the RAM initialization processing are the same as the processing contents of the RAM initialization processing of SA2 shown in the first embodiment.

FIG. 11 is a flowchart showing the contents of the RAM initialization processing. First, at S14, RA
It is determined whether M117 is in the initialized state or the restored state. Here, the initialized state refers to the RAM
117 means the state where initialization has been completed, and the restored state means
By the game state return process of S4, the game state data is
It refers to the state after returning to M117. R by S14
If it is determined that the AM 117 is in the initialized state and the restored state, the RAM initialization processing ends because there is no need to initialize the data stored in the RAM 117.
On the other hand, if it is determined in S14 that the RAM 117 is not in the initialized state or the restored state,
Since it is necessary to initialize the RAM 11
7 is initialized. Thereafter, the RAM initialization processing ends.

The pachinko gaming machine 1 according to the second embodiment
Now, the game state data indicating the game state being executed is EEP
A game state writing process, which is a process of writing to the ROM 220, is executed. By this game state writing process, the RAM 117
The game state data of the game control being executed, which is the same data as the game state data written to the
The game state data written to 0 is stored for a predetermined period of time even when the power supply to the game control microcomputer 115 is cut off.

Next, processing contents of the game state writing processing will be described. FIG. 12 is a flowchart showing the processing contents of the game state writing processing.

First, at S21, the EEPROM 220
It is determined whether or not the game state data is being written to the CPU. If it is determined in S21 that the game state data is being written, the process proceeds to S31 described below. On the other hand, S21
If it is determined that the game state data is not being written, the process proceeds to S22, and it is determined whether the pachinko gaming machine 1 is in a big hit state.

If it is determined in step S22 that the big hit state is present, the process proceeds to step S25 described later. On the other hand, if it is determined in S22 that the vehicle is not in the big hit state, the process proceeds to S23, and a process of checking the number of start memories and the value of the big hit determination random counter corresponding to each of the start memories is performed. Next, the process proceeds to S24, and it is determined whether or not the current time is in the process of changing the probability (probably changing). If it is determined in S24 that the probability is fluctuating, S29 described later is used.
On the other hand, if it is determined in S24 that the probability is not fluctuating, the process proceeds to S30 described later.

At S25, which is executed when it is determined in S22 that the game is in the state of the big hit, a process of checking the big hit symbol is performed. Next, the process proceeds to S26, and a process of checking the count value of the number of rounds in the big hit state is performed. Next, the process proceeds to S27, in which processing is performed to check the number of start memories and the value of the random counter for big hit determination corresponding to each start memory. Next, the process proceeds to S28, and it is determined whether or not the probability fluctuation state is currently continuing. If it is determined in S28 that the probability fluctuation state is not continuing, the process proceeds to S30 described later. On the other hand, if it is determined in S28 that the probability variation state is continuing, S
Go to 29.

In S29, a process of checking the remaining number of times of probability fluctuation, which is the number of remaining jackpots that can be generated before the end of the probability fluctuation state, is performed. Next, S30
Proceed to. In S30, EEPR as a game state storage unit
A process of writing game state data to a predetermined address of the OM 220 is performed. The game state data written here is S
23, various game data checked in S25, S26, S27 and S29. Next, the process proceeds to S31.

In S31, it is determined whether a power failure state has been detected based on the power failure detection signal from the power failure detection circuit 124b. The power failure state includes not only an actual power failure state but also a state in which power supply is cut off based on a power-off operation. If it is determined in S31 that the power outage state has not been detected, the game state writing process ends. On the other hand, when it is determined in S31 that the power failure state has been detected, the process proceeds to S32, and it is determined whether the timer is counting time. This timer is used to determine whether a predetermined period has elapsed since the occurrence of the power failure state.

If it is determined in S32 that the timer is counting, the process proceeds to S34 described later. On the other hand, if it is determined in S32 that the timer is not counting, the process proceeds to S3.
Then, the process proceeds to step S3, where the timer starts counting. Thereafter, the process proceeds to S34. In S34, it is determined whether or not the value of the timer has reached a predetermined value. The predetermined value is set to a short time, for example, about 10 to 60 minutes. If it is determined in S34 that the value of the timer has not reached the predetermined value, the process proceeds to S36 described later. on the other hand,
If it is determined that the value of the timer has reached the predetermined value, S3
Proceeding to S5, a process of clearing (initializing) the data stored in the EEPROM 220 is performed. Thereafter, the process proceeds to S36.

In S36, it is determined whether or not the power failure has been restored based on the power failure detection signal. The power failure recovery state in this case includes a case where power supply is started based on a power-on operation, in addition to a recovery from an actual power failure. If it is determined in S36 that the power outage state has not been restored, the process returns to S34, and the above-described processing is repeatedly executed until the power outage state is restored. On the other hand, if it is determined in S36 that the power outage state has been restored, the game state writing process ends.

By executing such a game state writing process, various game state data relating to the game control being executed in the game control microcomputer 115 are sequentially written into the EEPROM 220. Then, when the power supply to the game control microcomputer 115 is cut off due to a power failure or the like, the storage of various game state data when the power supply is cut off is held for a predetermined period.

Next, the processing contents of the above-described game state return processing in S4 will be described. FIG. 13 is a flowchart showing the processing contents of the game state return processing. First, S1
6, the process of reading the game state data from the EEPROM 220 and reading the game state data into the RAM 117 is started. Next, the process proceeds to S17, in which the RAM 117 sets an address of the RAM 117 for storing the game state data read from the EEPROM 220. Next, the process proceeds to S18, in which processing for storing the game state data read from the EEPROM 220 at the address set in S17 is performed. This allows
The game state data stored in the EEPROM 220 is RA
Each type is stored in M117 one by one.

Next, the process proceeds to S19, where the EEPROM 220
It is determined whether or not reading of all the game state data read from the game has been completed. If it is determined in S19 that reading of all game state data has been completed, the game state return process ends. On the other hand, if it is determined in S19 that reading of all game state data has not been completed, the process proceeds to S20. In S20, it is determined whether to change the address of the storage destination of the game state data. Here, it is determined whether it is necessary to change the address of the storage destination in order to store the game state data to be stored next to the game state data that has been stored so far.

If it is determined in S20 that the address is to be changed, the process proceeds to S1 to store the next game state data.
7, the above-described series of processing from S17 is repeated. On the other hand, if it is determined in S20 that the address is not to be changed, the process returns to S19, and the game state return process ends after reading of the stored game state data ends.

By executing such a game state return process, the game state data stored in the EEPROM 220 is stored in the RAM 117. This allows
Based on the game state data stored in the RAM 117,
The game control by the game control microcomputer 115 is restarted. That is, in the main routine of the game control program shown in FIG. 10, the processing subsequent to the output processing in S5 is sequentially executed based on the game state data restored by executing the game state restoration processing in S4. You.

Therefore, if the power failure is restored within a predetermined period after the power failure occurs, the EEPROM still remains
Since the game state data at the time of the power outage is stored in 220, the game control can be resumed from the game state at the time of the power outage by restarting the game control based on the game state data. Thereby, the player can be compensated for the occurrence of the power outage state, and if such compensation is not made, the player can be prevented from feeling dissatisfied. As a result, troubles that may occur between the player and the game arcade can be prevented.

When the power supply to the game control microcomputer 115 is cut off by the power-off operation of the pachinko gaming machine 1 performed when the game hall is closed, etc., when the game hall is closed, the game hall is closed. The power supply is cut off for a period longer than a predetermined period, such as the time until the opening of the store, so that the game state data stored in the EEPROM 220 is cleared in the game state writing process. That is,
If the power supply to the game control microcomputer 115 is cut off for a predetermined period, the EEPROM 22
The game state data stored in 0 is invalidated. For this reason, when the game hall is closed, etc., the power supply is turned off with the game side set to a game state advantageous to the player, and when the power is turned on at the time of opening the game hall, etc. on the next day, the state is changed from the advantageous state. It is possible to prevent a fraudulent activity in a game hall called a morning set, in which a player can start a game.

Further, by the game state writing process, the storage of the game state data is invalidated by software after a lapse of a predetermined period after the supply of power to the game control microcomputer 115 is cut off. Even if the side performs an illegal remodeling to extend the power supply operation time of the backup power supply 125 in order to keep the storage of the game state data for a long time, the invalidation of the storage of the game state data cannot be prevented. As a result, fraud can be reliably prevented.

Further, in the game state writing process, EEP
When the game state data stored in the ROM 220 is invalidated, the EEPROM is initialized (cleared), but such a memory initialization process can be electrically erased and written like an EEPROM. Game state data can be easily invalidated due to the characteristics of the memory.

It should be noted that EE is used as a memory to which game state data is written by the game state write processing of the second embodiment.
Although the PROM 220 is used, the present invention is not limited to this, and a memory capable of writing and erasing data at any time other than the EEPROM may be used as a memory for writing game state data.

In the first and second embodiments, the game state data is stored in the memory,
The example in which the game state data is invalidated after a predetermined period has elapsed after the occurrence of the power failure state has been described. However, as another example of the processing for invalidating the game state data, the following processing may be performed. Good. As in the case described above, the game state data is stored in the memory. Then, when a power failure occurs, the timer starts counting time. Then, without invalidating the storage of the game state data during the power failure state, it is determined whether or not the count value of the timer exceeds a predetermined period when the power failure state is restored. In this case, if it is determined that the time value of the timer has not passed the predetermined period,
The game control is restarted by using the stored game state data. On the other hand, when it is determined that the count value of the timer has exceeded the predetermined period, the storage of the game state data is invalidated. In this case, the process of invalidating the game state data may be performed by deleting the stored game state data or by starting the game control from the initial state ignoring the stored game state data. You may. By doing so, the same effect as the effect obtained in the above-described embodiment can be obtained.

Next, feature points of the modified examples of the present invention will be listed. (1) The pachinko gaming machine 1 constitutes a gaming machine in which a game is played by receiving power supply. The gaming machine has the following configuration. C shown in FIGS. 3 and 8
The PU 115a constitutes a game control means for performing a game control for controlling a game state. R shown in FIG.
The AM 117 or the EEPROM 220 shown in FIG. 9 constitutes a game state storage means for storing information (game state data) of the game state during the game. By the steps S38 to S41 shown in FIG. 7 or the steps S32 to S35 shown in FIG. 12, an invalidating means for invalidating the information stored in the gaming state storing means after a lapse of a predetermined period after the power supply is cut off. Is configured. As shown in S43 of FIG. 7 or S16 to S20 of FIG. 11, when the storage information of the game state not invalidated by the invalidation means is present in the game state storage means, the supply of power is performed. When started, the game control is started from the game state according to the stored information.

(2) The gaming machine of (1) further includes a power supply stop detecting means for detecting that power supply has been cut off, and the invalidating means comprises a power supply stop detecting means for supplying power. After a lapse of a predetermined period from the detection of the disconnection, the storage information of the game state storage means may be invalidated.

(3) The gaming machine of the above (1) has an external output means (point score) capable of outputting information on the gaming state during the game to the outside of the gaming machine when power supply is cut off. A storage counter 94a, an information output circuit 97, and connectors 78, 47, and 50), and external state display means (external state) provided outside the game machine and displaying game state information output from the external output means. Display device 200). With this configuration, when the power supply to the gaming machine is cut off, the gaming state when the power supply is cut off can be confirmed outside the gaming machine, and when the power failure is not restored, etc. Also, it is possible to perform appropriate compensation according to the game state.

(4) The external state display means is a storage means (EE) capable of storing game state information output from the external output means when power supply is cut off.
PROM 204).

(5) The gaming state storage means includes a memory (RA) capable of writing and erasing storage information.

(8) The disabling means is not to invalidate the information stored in the game state storage means after a predetermined period has elapsed since the power supply was cut off, Alternatively, the storage information of the game state storage means may be invalidated when a predetermined period has elapsed since the supply of power was cut off before that.

[0140]

Specific Examples of Means for Solving the Problems The CPU 115a shown in FIGS. 3 and 8 constitutes game control means for performing game control for controlling a game state. The RAM 117 shown in FIG. 3 or the EEPROM shown in FIG.
The game state storage means 220 stores information on the game state during the game (game state data). By the steps S38 to S41 shown in FIG. 7 or the steps S32 to S35 shown in FIG. 12, the invalidation means for invalidating the storage information of the game state storage means after a predetermined period has elapsed since the power supply was cut off. Is configured. As shown in S43 of FIG. 7 or S16 to S20 of FIG. 11, when the storage information of the game state which is not invalidated by the invalidation unit is present in the game state storage unit, the supply of the power is performed. When started, the game control is started from the game state according to the stored information.

(2) When the invalidation means invalidates the game state information stored in the game state storage means, as shown in step S41 of FIG. 7 or step S35 of FIG. Initializing information stored in the game state storage means.

[0142]

The effect of the concrete example of the means for solving the problems.
With regard to, information on the game state during the game is stored, and the information is not invalidated until a predetermined period has elapsed since the power supply was cut off. Therefore, even if the power supply is interrupted during a game due to a power outage or the like, if the power supply is interrupted for a shorter period than a predetermined period, such as a period until the power outage is promptly restored, the game The information of the inside game state is not lost. If the information of the game state during the game is stored when the supply of the electric power is started, the game control is started from the game state according to the stored information. Can be compensated. This can prevent the player from feeling dissatisfied when such compensation cannot be made, and can also prevent a trouble that may occur between the player and the game hall. . Further, when the power supply is interrupted for a period longer than a predetermined period, such as from when the game hall closes to when it opens, the stored game state information is invalidated. Even if the game is restarted, game control based on the stored information cannot be performed. For this reason, the power supply is turned off in a state in which the gaming area is set to a gaming state that is advantageous to the player, and a fraudulent activity in the gaming area in which the player can start the game from the advantageous state when the power is turned on is anticipated. Can be prevented. Further, since the storage information of the game state is invalidated after a predetermined period has elapsed since the supply of power was cut off, the storage of the storage information of the game state is simply performed at the game hall to store the storage information of the game state for a long time. Even if an unauthorized modification to extend the operation period of the backup power supply is performed, the invalidation of the storage of the game state storage information cannot be prevented, so that the illegal act can be surely prevented.

According to the second aspect, the following effect can be obtained in addition to the effect of the first aspect. When invalidating the stored game information, the stored information is initialized. The initialization process of such information is a relatively simple process performed at the start of the game control or the like. As a result, the invalidation of the game information can be easily performed.
