DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine which normally operates on the basis of an operating voltage, and more particularly, to a game machine or a game machine in which even if an electric accident such as a power failure occurs during a game played by a player, It relates to a pachinko machine that can store and save internal information on prize balls, etc., and can return to the state before the electric accident at the time of electric accident recovery and manage whether internal information is correctly stored or not. is there.

[0002]

2. Description of the Related Art In recent pachinko machines, various characters (special devices for facilitating winning a prize) are added to a game board in order to increase the interest of pachinko players by changing the content of the game. Prepare. For example, when a pachinko ball wins the starting winning opening, the fluctuating symbols displayed on the symbol display device such as a CRT start to fluctuate, and the symbols displayed after a certain period of time are aligned with a certain probability (for example, “7, 7, 7 "
In some cases, a special winning opening is continuously opened a predetermined number of times as a big hit, and a big hit image is displayed on a symbol display device. In such a pachinko machine, a great number of electronic control circuits are incorporated in various controls, and various circuits such as an accessory control circuit, a display circuit, or a prize ball payout control circuit include electronic circuits including a microcomputer. It is controlled by a control circuit.

[0003] For this reason, when an electric accident such as a short circuit of an electric line or a power failure occurs in a pachinko game store and the operating voltage supplied to the electronic control circuit decreases, the operation of the electronic control circuit stops. As a result of the operation of the various circuits being stopped, the operation of the entire pachinko machine is also immediately stopped. Therefore, even if an electrical accident occurs, for example, while a special winning opening is continuously opened a predetermined number of times as a jackpot, the operation is immediately stopped, and the player playing the game is astonished. become.

[0004]

However, in the case of such a pachinko machine, it is not possible to sufficiently cope with such an electric accident, and after the electric accident is repaired, the pachinko machine is supplied to the electronic control circuit. Even when the voltage recovered, the electronic control circuit only returned to the initial state. for that reason,
The operation of various circuits only returns to the initial state, and does not return to the open state of the big win as a jackpot during the game before the electric accident, so that the disadvantage of the player becomes extremely large. In such a case, the pachinko game store merely responds to the award ball based on the player's request as appropriate, and the pachinko machine itself cannot respond to the electric accident. In this case, it is desirable to store and save the game state information and the like, but the stored game information may not be correctly stored.

[0005] The present invention has been made to solve the above-mentioned problem, and stores and saves internal information such as game information even when an electric accident occurs during the game.
It is an object of the present invention to provide a pachinko machine capable of returning to a state before an electric accident at the time of recovery from the electric accident and managing whether or not internal information is correctly stored.

[0006]

According to a first aspect of the present invention, there is provided a pachinko machine according to the present invention, wherein a power supply capable of supplying an operating voltage and a backup voltage and internal information relating to a game or a prize ball are stored. Storage means capable of supplying a backup voltage from the power supply to the storage means when the operating voltage drops below a predetermined value, and storing the internal information stored in the storage means. A pachinko machine that can be used, wherein the internal information includes:
Management information for managing whether or not the internal information stored in the storage means is correctly stored is added, and after the operating voltage drops to a predetermined value or less, the operation voltage returns to a predetermined value or more. Reading the internal information stored in the storage means, when returning to a state before the operating voltage drops below a predetermined value, based on the management information,
It is characterized by comprising control means for judging whether or not the internal information is correctly stored.

[0007] In the pachinko machine having such features, the storage means can store internal information on the game state, but an electric accident occurs during the game, and the operating voltage of the pachinko machine is lower than a predetermined value. In this case, the backup voltage is supplied from the backup power supply to the storage unit, and the internal information stored in the storage unit is set in the storage state. Then, by adding the management information to the internal information, the control unit can determine whether or not the internal information is correctly stored.
Thereafter, when the operating voltage returns to a predetermined value or higher, the pachinko machine can return to the state before the electric accident by reading the internal information stored in the storage means under the management by the management information. It is possible for itself to respond to an electrical accident such as a power failure.

Therefore, even if an electric accident such as a power failure occurs in a game state in which a special winning opening is opened as a "big hit", the internal information such as the game information is stored and stored in the storage means. Then, by reading out the internal information under the management by the management information at the time of recovery from the electric accident, it is possible to return to the gaming state before the electric accident. This makes it possible to respond to electrical accidents such as power outages,
There is no disadvantage to the player. On the other hand, even if it returns to the state before the electric accident based on incorrect internal information, it cannot be said that it will be suitable for the player's interest as a result, so the internal information is used only when the management information is correct It is possible to do.

Further, according to the pachinko machine according to the present invention,
Detecting means for detecting an operating voltage; a backup power supply capable of supplying a backup voltage; a storing means capable of storing internal information relating to a game or a prize ball; A pachinko machine which can supply a backup voltage from the backup power supply to the storage means when detecting that the internal information has been reduced, and store the internal information stored in the storage means. Adds management information for managing whether or not the internal information stored in the storage means is correctly stored, and further, when the operating voltage drops to a predetermined value or less, the storage means A signal blocking unit for stopping access, and enabling access via the signal blocking unit when the operating voltage returns to a predetermined value or more, When the internal information stored in the storage unit is read out and returned before the operating voltage drops below a predetermined value, it is determined whether or not the internal information is correctly stored based on the management information. It is characterized by comprising a control means for performing.

[0010] In the pachinko machine having such features, the storage means can store the internal information relating to the payout of the game or the prize ball. The detecting means detects the operating voltage of the pachinko machine, and when detecting that the operating voltage has dropped below a predetermined value, supplies the backup voltage from the backup power supply to the storage means and stores the backup voltage in the storage means. The internal information is stored, and the signal blocking unit stops accessing the storage unit. Then, by adding the management information to the internal information, the control unit can determine whether or not the internal information is correctly stored. afterwards,
When detecting that the operating voltage has returned to a predetermined value or higher, the detection means enables access via the signal cutoff means under the management of the management information and reads out the internal information stored in the storage means. Thus, the gaming state before the operating voltage drops below the predetermined value can be returned, and the pachinko machine itself can respond to an electric accident such as a power failure.

Therefore, even if an electric accident such as a power outage occurs in a game state in which a special winning opening as a “big hit” is opened, the internal information and the like are stored and saved, and the electric accident is performed. By reading the internal information at the time of recovery,
It is possible to return to the game state before the electric accident. As a result, it is possible to respond to an electric accident such as a power failure, so that the player is not disadvantaged. Further, by stopping the signal cutoff unit from accessing the storage unit, it is possible to prevent the storage unit from being adversely affected by the operating voltage falling below a predetermined value. On the other hand, even if it returns to the state before the electric accident based on incorrect internal information, it cannot be said that it will be suitable for the player's interest as a result, so the internal information is used only when the management information is correct It is possible to do. The operation of the control means may be stopped when the signal cutoff means stops accessing the storage means. Preferably, the control means includes an accident countermeasure circuit for coping with an electric accident.

The control means reads the management information stored in the storage means before the operating voltage drops below the predetermined value, and reads out the management information when the operating voltage returns to the predetermined value or more. It is desirable to determine whether or not the information matches the management information. Then, it is determined whether or not the internal information is correctly stored based on whether or not the management information before the operating voltage drops below the predetermined value matches the management information when the operating voltage returns to the predetermined value or higher. it can. That is, when the management information matches before and after the change in the operating voltage, it can be grasped that the internal information is correctly stored. However, when the management information does not match before and after the change in the operating voltage, the internal information stored in the storage means is recognized. It can be understood that the information is likely to be wrong.

It is preferable that an automatic erasing means is provided for automatically erasing the internal information stored in the storage means when the control means determines that the internal information is not correctly stored. . This is based on incorrect inside information, and even if it returns to the state before the electric accident, it will not be in the interest of the player as a result, and if it is wrong inside information, it will be erased. Because it is desirable to take. Further, the management information may be a check byte added to the internal information or a checksum that is a total of the internal information. Specifically, when the check byte is used, for example, when the internal information is “111”, for example, “55H” is added to the internal information as the check byte. On the other hand, when using checksums,
For example, when the internal information is "0001", the sum "1H" is added to the internal information as a checksum, but the checksum changes according to the contents of the internal information. In the case of such a checksum, since it changes according to the internal information, there is an advantage that fraudulent acts can be prevented. However, if the amount of internal information is large, there is a disadvantage that it takes time to calculate the sum thereof. On the other hand, in the case of a check byte, since it is fixed, for example, "55H",
In contrast to the merit that it is easy to determine whether the check byte before the operating voltage drops below the predetermined value and the check byte when the operating voltage returns to the predetermined value or more are easy. If the contents of the check byte are known to outsiders, there is a disadvantage that fraudulent acts are likely to occur.

Further, it is desirable to have an erasing means for erasing the internal information stored in the storage means. This is because the manager of the pachinko game store sometimes wants to erase the internal information and the like stored in the storage means for management purposes, and the operation of the deletion means can easily meet such a demand. Specifically, if it is not possible to delete the internal information or the like stored in the storage means, for example, the internal information may cause an electric accident in a state (for example, a jackpot) advantageous to the player, and the game may not wait for the electric accident to be repaired. After redressing the electric accident after pachinko games are compensated for by the player, another player who is trying to play the game, even though he has not played any game yet, is in an advantageous condition for the player If suddenly appears, the disadvantage of the pachinko game store is great, so it is necessary to delete the internal information and the like stored in the storage means to prevent such a situation. In this case, the erasing means is desirably a switch for erasing operation, and is preferably provided on the back side of the pachinko machine so as to prevent the pachinko game shop customer or the like from easily touching the switch.

Preferably, the erasing means is a switch that is linked with opening of the front door of the pachinko machine. In this case, when the pachinko game store manager or the like opens the front door of the pachinko machine when the operating voltage is cut off, the switch operates in conjunction with the opening of the front door, and the internal information stored in the storage means. To delete. As a result, the manager of the pachinko game arcade can very easily meet the desire to delete the internal information and the like for management.

Preferably, the erasing means is provided with time setting means for setting a supply time of the backup voltage, and after the supply time elapses, the internal information stored in the storage means is desirably erased. . Thereby, the time setting means sets the supply time (for example, 3 hours) of the backup voltage, and when the supply time (for example, 3 hours) has elapsed, the internal information stored in the storage means is deleted.
This means that if it takes more than 3 hours to repair an electrical accident such as a power outage, it is unlikely that customers who were in pachinko parlors have been waiting for the repairs for more than three hours. In some cases, the internal information stored in the storage means is unnecessary. In such a case, when the supply time (for example, 3 hours) elapses, the internal information stored in the storage means is automatically deleted, so that the manager of the pachinko game store etc. can delete the internal information stored in the storage means. There is no need to perform an erasing operation.

The main processing of the prize ball payout control processing performed by the CPU 83A of the main board 53 includes the winning ports 18, 23, 24, 25, 26, 29, 3
When a winning to 0 is detected, each winning opening 18, 23, 2

Is subtracted, and the data of the winning number obtained by the subtraction is again stored in the RAM.
A winning subtraction process to be stored in 83C is executed.

The CPU 83A determines that a pachinko ball has won the special winning opening 26 and that a pachinko ball detection signal has been input from the special winning opening count switch 26B, or that the V zone at the center of the special winning opening 26 When a pachinko ball is won and a pachinko ball detection signal is inputted from the V switch 26A, the data of the number of winning prize holes as the information of the number of winning prize holes is read from the RAM 83C. Then, the CPU 83A performs a special winning opening prize process of adding 1 to the data of the winning prize opening number and storing the added data of the winning prize opening number again in the RAM 83C.

The special winning opening winning subtraction process stored in the M83C is executed.

The CPU 83A is provided with a first type starting port 23.
When the pachinko ball is won and the input of the pachinko ball detection signal from the starting port switch 23A is detected, the RAM
Data of the winning opening winning number is read from 83C. Then, the CPU 83A adds 1 to the data of the number of winning openings, and again adds the data of the number of winning openings to the RAM.
A first-class start-up winning process stored in the 83C is performed. Conversely, when paying out a prize ball, the CPU 83A reads the data of the number of winning openings from the RAM 83C, subtracts 1 from the data of the number of winning openings, and again subtracts the data of the number of winning openings from the RAM 83C. The first to memorize
A seed starting opening winning subtraction process is executed. Information on the game and the prize ball, such as the data of the winning opening winning number data, the winning number data, and the winning winning number winning number data, becomes the internal information stored in the RAM 83C, and the internal information is used to cause an electric accident during the game. If the data is not erased from the RAM 83C and does not return to the state before the electric accident after recovery from the electric accident, the disadvantage of the player becomes extremely large. However, the accident countermeasure circuit 8 described later
The internal information is stored and stored in the RAM 83C by the 3F, and when the internal information is read by the CPU 83A, the state can be returned to the state before the electric accident.

Next, an accident countermeasure circuit 83F for coping with an electric accident will be described with reference to FIG. FIG.
Is composed of an accident countermeasure circuit 83F and a main part extracted from the circuit of the main board 53. The accident countermeasure circuit 83F
A power supply monitoring circuit 83G for monitoring a voltage for operating a CPU 83A and the like provided on the main board 53;
A signal cutoff circuit 83H for preventing access to C,
Decoder 8 for selecting a predetermined RAM 83C from U83A
3J and an erasing operation switch 8 as erasing means for erasing game state information and the like stored in the RAM 83C.
3K or the like. In addition, the accident countermeasure circuit 83F
Is provided with a main substrate 53 and another backup power supply substrate 83L so as to be connectable. The backup power supply board 83L is provided with a large-capacity capacitor C1 as a backup power supply, and a connector C2 connected to the large-capacity capacitor C1 is connected to a connector C on the main board 53 side.
3 can be connected and disconnected.

The reason why the connectors C2 and C3 can be connected to and disconnected from each other is that the backup power supply board 83
When the L connector C2 is disconnected from the connector C3 on the main board 53 side, the internal information stored in the RAM 83C is erased, so that the internal information stored in the RAM 83C is not decrypted, and This is because it can be prevented. Also, the pachinko parlor manager can easily disconnect the connector C2 and the connector C3 by disconnecting the connector C2 and the connector C3.
Internal information stored in the AM83C can be erased.

When the connector C2 and the connector C3 are connected, the electric charge stored in the large-capacity capacitor C1 causes the terminal GND of the RAM 83C and the RAM 83C to be connected.
A backup voltage can be supplied to the terminal Vcc.
Since the operating voltage is applied to the terminal Vcc of the RAM 83C via the diode D1, the operating voltage (for example, 5 volts) is normally applied to the terminal GND of the RAM 83C.
Only when the operating voltage drops to a predetermined voltage value (for example, 4 volts or less), the backup voltage is applied by the large-capacity capacitor C1. In this case, the operating voltage (for example, 5 volts) is normally applied to the large-capacity capacitor C1 via the diode D1.
, The large-capacity capacitor C1 is charged, and the backup voltage of the large-capacity capacitor C1 can be supplied to the RAM 83C for a predetermined time.

Next, the CPU 83 provided on the main board 53
The operation of the accident countermeasure circuit A will be described with reference to FIG. FIG. 6 is a flowchart illustrating the operation of the pachinko machine according to the embodiment for preventing accidents. The power supply monitoring circuit 83G functioning as a detecting means for detecting the operating voltage includes:
Terminal GND of RAM83C and terminal Vcc of RAM83C
Then, the operating voltage applied between the two is monitored, and it is determined whether or not this operating voltage is at the time of voltage drop (for example, when the voltage is 5 volts or less) (S1). The operating voltage is a predetermined voltage value (for example, 5
Volts) or more (S1: NO), the CPU 83A
Stores the internal information about the game or the prize ball in the RAM 83
C (S2), and executes an operation such as payment of a prize ball based on the internal information (S3). And CPU83A
Determines whether the operation based on the internal information stored in the RAM 83C has been completed (S4), and when the operation has been completed (S4: YES), deletes the internal information (S5).
If the operation is not completed (S4: NO), S3 is executed. For example, if a predetermined number of prize balls are paid out for one winning, the payout operation is completed, and the data for the winning is erased from the RAM 83C.

On the other hand, when an electric accident occurs and the operating voltage drops to a predetermined voltage value (for example, 5 volts or less) (S
1: YES), a signal (hereinafter referred to as a voltage drop signal) indicating a decrease in the operating voltage is output from the monitor output terminal K1 to the signal cutoff circuit 83H and the CPU 83A in order to prevent the CPU 83A from accessing the RAM 83C (S6). .
The CPU 83A that has received the voltage drop signal
The internal information stored in C is, for example, "101
0. . . If the data is “101101”, a tick byte (for example, “5
5H ”) is stored (S7). Thereafter, the CPU 83A itself is reset (S8). And
The signal cutoff circuit 83H that has received the voltage drop signal performs a signal cutoff operation (S9), and the CPU 8 via the decoder 83J.
The access from the 3A to the RAM 83C is blocked by the signal blocking circuit 83H.

When the operating voltage drops to a predetermined voltage value (eg, 4 volts or less), the CPU 83A may malfunction and adversely affect the RAM 83C. Is the CP
This is because the signal from the U83A to the RAM 83C is cut off, thereby preventing an adverse effect due to the malfunction. And
Even when the operating voltage drops to a predetermined voltage value, the terminals GND and R of the RAM 83C are controlled by the diode D1.
Between the terminal Vcc of the AM83C and the large-capacity capacitor C
1 to supply a backup voltage (S10).
The internal information stored in the AM83C is saved.

Thereafter, the power supply monitoring circuit 83G
The operating voltage applied between the terminal GND of the 3C and the terminal Vcc of the RAM 83C is monitored, and it is determined whether or not the operating voltage is reduced (S11). If the electric accident is not repaired (S11: NO), S9 and S10 are repeated. Thereafter, when the electric accident has been repaired and the operating voltage that has dropped below the predetermined value has returned to above the predetermined value (for example, 5 volts) (S11: YES), a voltage drop signal is sent from the monitoring output terminal K1 to the CPU 83A and the signal cutoff circuit 83H. Is no longer output to (S12). Thereby, the CPU 83A
Is released, and the signal cutoff circuit 83H is released.
Is stopped and the signal C is transmitted through the decoder 83J.
The access from the PU 83A to the RAM 83C is permitted.

When the operating voltage returns to the predetermined value or more, the internal information and the tick byte are stored in the RAM 83C, so that the CPU 83A reads the tick byte stored in the RAM 83C (S13). At this time, the CPU 83A determines whether the tick byte “55H” added at the end of “1010 ... 101101”, which is the internal information stored in the RAM 83C, is correct (S14). That is, the tick byte (management information) stored in the RAM 83C before the operating voltage drops below the predetermined value, and the tick byte (management information) read from the RAM 83C when the operating voltage returns to the predetermined value or higher. Management information). This is because when the operating voltage returns to a predetermined value or more, the tick byte read from the RAM 83C becomes, for example, “53H” and before the operating voltage drops to a predetermined value or less.
This is because it may not match the tick byte stored in 83C.

Only when the data of "55H" of the tick byte is correctly stored (S14: YE
S), the CPU 83A reads the internal information (S1).
5) Return to the state before the electric accident (S16) and execute the operation corresponding to the internal information. As a result, even if an electrical accident such as a power failure occurs during a game played by a player, for example, even in a gaming state in which the special winning opening 26 is opened as a "big hit", a backup voltage is supplied to supply internal information and the like. RA
Since the data can be stored and stored in the M83C, it is possible to return to the game state before the electric accident after repairing the electric accident, and to cope with an electric accident such as a power failure. I will not give.

On the other hand, an electric accident occurs during the game, and a backup voltage is applied to the RAM 83C to store and store the internal information and the tick byte. However, the data of “55H” of the tick byte remains correctly. If not (S1
4: NO), when the electrical accident is restored, even if the CPU 83A reads the internal information, it is not always possible to return to the state before the electrical accident, so the internal information is automatically deleted (S17). By using the management information of such a tick byte, if the management information is correct, it can be grasped that the internal information is correctly stored. If the management information is not correct, the internal information stored in the RAM 83C is incorrect. It can be understood that there is a high possibility that If the internal information is incorrect, even if it returns to the state before the electric accident based on it, it cannot be said that it will be in the interest of the player as a result, so if it is incorrect, delete it. It is desirable to take measures such as doing. Therefore,
Only when the management information is correct, it is possible to adopt a mode of using the internal information.

The automatic erasing means for automatically erasing the internal information stored in the RAM 83C includes the RA
As shown in FIG. 8A, the internal information stored in the M83C is, for example, "1010 ... 101101".
8B, the CPU 83A overwrites and clears the data like "0000 ... 000000" as shown in FIG. 8B. However, it is not always necessary to use check bytes as management information.
For example, a checksum that is the sum of internal information may be used. When the checksum is used, for example, when the internal information is “0001”, the sum “1H” is added to the internal information. However, since the checksum changes according to the internal information, fraud is prevented. Although there is a merit that can be obtained, when the amount of internal information increases, there is a demerit that it takes time to calculate the sum.

On the other hand, in the case of a check byte, for example, "5
5H ", the check byte" 55H "before the operating voltage drops below the predetermined value and the check byte when the operating voltage returns to the predetermined value or higher are checked. While there is a merit that judgment is easy, there is a disadvantage that fraud is likely to occur. In addition, since the erase operation switch 83K that can cut off the backup voltage is provided on the wiring connected to the terminal Vcc of the RAM 83C, the manager of the pachinko game store or the like may change the erase operation switch 83K as necessary. By operating to cut off the backup voltage supply, RA
Internal information stored in the M83C can be deleted.

When the manager of the pachinko parlor operates the erase operation switch 83K in this manner, the internal information stored in the RAM 83C is deleted. As a result, the pachinko parlor manages the internal information and the like stored in the RAM 83C. It is possible to very easily meet the demand for the upper erasure. This is because the occurrence of an electrical accident is just before the end of business hours,
If the game state information stored and stored in the 83C is an advantageous state (for example, a jackpot) for the player, the player does not play any game at the time of opening the game store the next day after the electric accident is repaired. Nevertheless, if an advantageous state for the player suddenly appears, the disadvantage of the game store is great, and it is necessary to erase the internal information stored and stored in the RAM 83C to prevent such a situation. It is.

The backup power supply board 83L and the main board 53 do not necessarily have to be separate boards. In the case of this embodiment, for example, a transistor may be used instead of the diode D1.
Instead of connecting to the terminal CE of C, it may be connected to the terminal WR of the RAM 83C. As means for erasing the internal information stored in the RAM 83C, as shown in FIG. 7, a timer circuit T1 may be provided as time setting means for setting the supply time of the backup voltage.

More specifically, the collector terminal of the transistor T2 is connected to the terminal Vcc of the RAM 83C, the output terminal of the timer circuit T1 is connected to the base terminal of the transistor T2, and the emitter terminal of the transistor T2 and the operation of the timer circuit T1 are connected. The application voltage and the backup voltage by the large-capacity capacitor C1 are applied. After the supply time (for example, 3 hours) of the backup voltage has elapsed, the timer circuit T
When the transistor 1 operates to lower the output to the base terminal of the transistor T2, the transistor T2 becomes inactive, so that the application of the backup voltage to the RAM 83C is cut off and the internal information stored in the RAM 83C is erased. .

When the supply time (for example, 3 hours) of the backup voltage elapses as described above, the internal information stored in the RAM 83C is automatically deleted, so that the manager of the pachinko game store stores the information in the RAM 83C. There is no need to perform an operation for erasing the internal information that has been performed. Also,
The erasing means for erasing the internal information stored in the RAM 83C may be an erasing switch that works in conjunction with the opening of the glass door 9 (front door) of the pachinko machine 1 when the operating voltage is cut off. In this case, the erase switch 83K
Is a switch contact a and its operating piece b, as shown in FIG.
A switch (not shown) that is turned on / off by contact / non-contact with the switch may be used.

As a specific mode, when the operation piece b is pressed with the glass door 9 closed, the pressed operation piece b and the switch contact a come into contact with each other, and the erase switch 83K is turned on. In contrast, when the glass door 9 is opened, the operating piece b is not pressed, so that the operating piece b and the switch contact a are in a non-contact state, and the erasing switch 83K is turned off. The erase switch 83K is attached near the glass door 9.

Then, the manager of the pachinko game store or the like turns off the operation power and turns the glass door 9 of the pachinko machine 1 on.
Is released, the operating piece b of the erasing switch 83K is turned off in conjunction with the opening of the glass door 9, and the output signal from the erasing switch 83K is supplied under the supply of the backup voltage. CPU 83 detected
A is configured to erase the internal information stored in the RAM 83C. As a result, the operation of opening the glass door 9 of the pachinko machine 1 with the operation power supply turned off allows the manager or the like of the pachinko game shop to easily erase the internal information and the like stored in the RAM 83C. .

The CPU 83 provided on the main board 53
A, a ROM 83B, a RAM 83C, an input circuit 83D, an output circuit 83E, and a CP provided on the award ball control board 55.
U84A, ROM84B, RAM84C, input circuit 84
D and the output circuit 84E constitute control means. The winning opening switches 18A, 29A, 30A, the lower winning opening switches 24A, 25A, the starting opening switch 23A, the V switch 26A, and the special winning opening counting switch 26B constitute a winning detecting means. Further, the RAM 83 of the main board 53
C functions as winning number storage means.

As described in detail above, according to the pachinko machine 1 of this embodiment, the power supply monitoring circuit 83G for detecting the operating voltage, the large-capacity capacitor C1 capable of supplying the backup voltage, and the game or prize ball. RAM83C capable of storing internal information on the payout state
When the power supply monitoring circuit 83G detects that the operating voltage has dropped below a predetermined value, the backup voltage is supplied from the large-capacity capacitor C1 to the RAM 83C,
A pachinko machine 1 capable of storing internal information stored in the RAM 83C, wherein the internal information includes the RAM 8
A check byte (management information) for managing whether or not the internal information stored in the 3C is correctly stored is added, and when the operating voltage drops below a predetermined value,
A signal cutoff circuit 83H for stopping access to the RAM 83C and an access via the signal cutoff circuit 83H when the operating voltage has returned to a predetermined value or higher, and RA
A CPU 83A is provided that can read internal information stored in the M83C and return to a state before the operating voltage drops below a predetermined value. Incidentally, the signal cutoff circuit 83H
When stopping the access to the RAM 83C, the operation of the CPU 83A (control means) may be stopped as necessary.

Accordingly, the power supply monitoring circuit 83G detects the operating voltage of the pachinko machine 1, and supplies a backup voltage from the large-capacity capacitor C1 to the RAM 83C when detecting that the operating voltage has dropped below a predetermined value. Then R
The internal information stored in the AM 83C is saved, and the signal cutoff circuit 83H stops accessing the RAM 83C. When detecting that the operating voltage has returned to or above the predetermined value after the operating voltage has dropped to or below the predetermined value, the power supply monitoring circuit 83G stops the signal cutoff operation and
Allow access from PU83A to RAM83C,
The internal information stored in the AM83C can be read. In this case, since the check byte (management information) is added to the internal information, it can be grasped whether or not the internal information is correctly stored. Only when the check byte (management information) is correct, the internal information is read and the operation is performed. While the game state can be returned to the state before the use voltage dropped below the predetermined value, if the check byte (management information) is incorrect, the internal information can be automatically erased.

It should be noted that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention. Good. As a backup power supply for supplying a backup voltage, for example, a battery such as a storage battery, a nickel-cadmium battery, a dry battery, or a nickel-metal hydride battery may be used.
Further, as the storage means for storing the information on the game state, for example, it is not always necessary to store and store the information in the normally used RAM 83C, and the internal information may be transferred and stored from the RAM 83C to, for example, a backup memory. Further, when the control circuit detects that an electric accident such as a power failure has occurred, the operation of the CPU 83A may be immediately stopped.

Further, the pachinko machine is not limited to the above-mentioned first class pachinko machine, but may be applied to, for example, a second class pachinko machine and a third class pachinko machine. As a memory for storing and storing internal information and the like, a commonly used RAM 83 is used.
A transfer memory other than C may be used to transfer internal information and the like from the normally used RAM 83C to the transfer memory immediately before storage. Further, in addition to the configuration in which the erasing operation switch 83K is provided for each pachinko machine, a plurality of pachinko machines may be collectively operated by one erasing operation switch.

[0069]

As described above, according to the pachinko machine according to the present invention, even if the electric accident occurs, for example, in a gaming state such as opening of a special winning opening as a jackpot during the game, for example, Internal information such as jackpot information is stored and stored, and the internal information stored in the storage unit after the electric accident is repaired can be read out under the management of the management information, so that the state before the electric accident is returned. It is possible to respond to an electric accident without giving a disadvantage to the player. Then, since management information for managing whether or not the internal information stored in the storage means is correctly stored is added to the internal information, it is managed whether or not the internal information is correctly stored. be able to. Further, since the signal cutoff unit stops accessing the storage unit, it is possible to prevent an adverse effect on the storage unit due to the operating voltage dropping below a predetermined value.

The control means reads the management information stored in the storage means before the operating voltage drops below the predetermined value, and reads out the management information when the operating voltage returns to the predetermined value or more. When it is determined whether or not the received information matches the management information, it can be understood that the internal information is correctly stored.
That is, when the management information matches before and after the change in the operating voltage, it can be grasped that the internal information is correctly stored. On the other hand, when the management information does not match before and after the change in the operating voltage, the management information is stored in the storage unit. The user can know that the internal information is likely to be wrong, and can easily determine whether or not the internal information is correctly stored.

When the control means determines that the internal information is not correctly stored, the apparatus has an automatic erasing means capable of automatically erasing the internal information stored in the storing means. The internal information stored in the storage means can be prevented from being read out after the electrical accident has been repaired by erasing the internal information stored in the storage means. When a check byte is used as the management information, it is determined whether or not the check byte before the operating voltage drops below the predetermined value and the check byte when the operating voltage returns to the predetermined value or higher match. Easy. Further, when a checksum is used as the management information, the checksum changes according to the internal information, thereby preventing fraud. Further, in the case where an erasing means for erasing the internal information stored in the storage means is provided, the operation of the erasing means erases the internal information stored in the storage means. Can be met very easily.

In the case where the erasing means is a switch that operates in conjunction with opening of the front door of the pachinko machine when the operating voltage is cut off, the pachinko game shop manager or the like may be able to operate the pachinko machine when the operating voltage is cut off. When the front door is opened, the switch operates in conjunction with the opening of the front door, so that the internal information stored in the storage means is deleted. As a result, the manager of the pachinko parlor wants to delete the internal information and the like in management. Can be met very easily. Further, the erasing means is provided with a time setting means for setting the supply time of the backup voltage, and when the supply time (for example, 3 hours) elapses, the internal information stored in the storage means is automatically erased. In this case, it is not necessary for the manager of the pachinko game store or the like to perform an operation for erasing the internal information stored in the storage means.
