2. Description of the Related Art In recent pachinko machines, various kinds of accessories (special devices for facilitating winning a prize) are added to a game board to increase the interest of the pachinko machine player by changing the game contents. Prepare For example, when a pachinko ball wins the starting winning opening, the variable symbol displayed on the symbol display device such as a CRT starts to vary, and after a certain period of time, the symbols displayed are aligned with a certain probability (eg, "7, 7, 7 "
There is a big hit image is displayed on the symbol display device while the big winning opening is continuously opened a predetermined number of times as a big hit. Such a pachinko machine incorporates a large number of electronic control circuits for various controls, and various circuits such as an accessory control circuit, a display circuit, or a prize ball payout control circuit are electronic devices including a microcomputer or the like. It is controlled by the control circuit.

Therefore, when an electric accident such as a short circuit of an electric line or a power failure occurs at a pachinko game shop and the operating voltage supplied to the electronic control circuit drops, the operation of the electronic control circuit is stopped, As a result of the operation of various circuits being stopped, the operation of the entire pachinko machine is also immediately stopped. Therefore, for example, even if an electric accident occurs while the special winning opening is continuously opened a predetermined number of times as a jackpot, the operation immediately stops and the player who is playing is surprised. become.

[0004]

However, in the case of such a pachinko machine, such an electric accident has not been sufficiently dealt with, and repair of the electric accident is completed and the electric accident is supplied to the electronic control circuit. The electronic control circuit only returned to the initial state, even when the voltage that had recovered was restored. for that reason,
The operation of various circuits only returns to the initial state, and does not return to the open state of the special winning opening as a big hit during the game before the electric accident, so that the disadvantage of the player becomes extremely large. In such a case, the pachinko gaming shop merely responded to the player's offer, such as paying back prize balls appropriately, and the pachinko machine itself could not cope with the electric accident. In that case, it is desirable to store and save the game state information and the like, but the stored game information may not be stored correctly.

The present invention has been made to solve the above-mentioned problems, and even if an electric accident occurs during a game, the internal information such as game information is divided into a plurality of storage areas and stored. The purpose of the present invention is to provide a pachinko machine that can be saved and stored and can be restored to the state before the electric accident when the electric accident is recovered, and can manage whether or not the internal information is correctly stored for each storage area. To

[0006]

In order to achieve the above object, according to the pachinko machine of the present invention, a power supply capable of supplying an operating voltage, a backup power supply capable of supplying a backup voltage, a game or a prize ball, etc. Internal information regarding storage means capable of storing a storage area divided into a plurality of areas, and a backup voltage is supplied to the storage means from the backup power source when the operating voltage drops below a predetermined value, A pachinko machine capable of storing internal information stored in a storage unit, wherein the internal information is a management for managing whether the internal information stored in the storage unit is correctly stored. Information is added to each of the storage areas, and after the operating voltage drops below a predetermined value, it returns to above a predetermined value and is stored in the storage means. Based on the management information, it is determined whether or not the internal information is correctly stored when the internal information stored therein is read out and returned to the state before the operating voltage drops below a predetermined value. When the control unit determines that the management information is not correctly stored for each storage area, the control information is stored in a storage area that is not correctly stored. It is characterized by comprising an automatic erasing means capable of automatically erasing existing internal information.

In the pachinko machine having such characteristics, the storage means can store internal information about a game or a payout state of prize balls in each storage area, but an electric accident occurs during the game. When the operating voltage of the pachinko machine drops below a predetermined value, the backup voltage is supplied from the backup power supply to the storage means to bring the internal information stored in the storage means into a saved state. Then, by adding the management information to the internal information of each storage area, the control means can determine whether or not the internal information is correctly stored for each storage area based on the management information. Then, when the operating voltage returns to a predetermined value or higher, the internal information stored in each storage area of the storage means is read out under the control of the management information to return to the state before the electric accident. Therefore, 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 failure occurs in a game state in which the special winning opening is opened as, for example, a "big hit", internal information such as the game information is stored in each storage area of the storage means. It is possible to return to the gaming state before the electric accident by storing and saving the information in the memory and reading the internal information under the control of the management information when the electric accident is recovered.
As a result, it becomes possible to deal with an electric accident such as a power failure and the player is not disadvantaged. On the other hand, even if it returns to the state before the electric accident based on the incorrect internal information, it cannot be said that it will be suitable for the player's profit as a result. Therefore, the internal information will be displayed only when the management information for each storage area is correct. It becomes possible to adopt a mode to be used, and a mode suitable for a player's profit can be adopted.

According to the pachinko machine according to the present invention,
The detection means for detecting the operating voltage, the backup power supply capable of supplying the backup voltage, the storage means capable of storing internal information regarding a game or a prize ball in a plurality of storage areas, and the detection means are A pachinko machine that can store internal information stored in the storage means by supplying a backup voltage from the backup power supply to the storage means when detecting that the operating voltage has dropped below a predetermined value. In the internal information, management information for managing whether or not the internal information stored in the storage means is correctly stored is added to each of the storage areas, and the operating voltage is further added. When the voltage drops below a predetermined value, the signal cut-off means for stopping access to the storage means, and when the operating voltage returns above a predetermined value, When the internal information stored in the storage means is read out and returned before the operating voltage drops below a predetermined value, the internal information is stored correctly so that access through the signal blocking means is possible. It is provided with control means for judging whether or not each storage area is based on the management information, and the control means judges for each storage area that the management information is not correctly stored. In this case, it is characterized by comprising an automatic erasing means capable of automatically erasing the internal information stored in the storage area in which the management information is not correctly stored.

In the pachinko machine having such a feature, the storage means can store internal information regarding payout of games or prize balls for each storage area. When the detecting means detects the operating voltage of the pachinko machine and detects that the operating voltage has dropped to a predetermined value or less, the backup voltage is supplied to the storage means from the backup power source and stored in the storage means. The internal information stored is saved and the signal blocking means stops accessing the storage means. Then, by adding the management information to the internal information, the control means can determine whether the internal information is correctly stored in each storage area based on the management information. After that, when the detecting means detects that the operating voltage has returned to a predetermined value or more, the detecting means enables access through the signal blocking means under the control of the management information, and stores it in each storage area of the storage means. By reading the internal information that is stored, it is possible to return to the gaming state before the operating voltage drops below a predetermined value, and the pachinko machine itself can 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 the special winning opening as a "big hit" is opened, the internal information and the like are stored in each storage area of the storage means. Then, by saving and reading the internal information when the electric accident is recovered, it is possible to return to the gaming state before the electric accident. As a result, it becomes possible to deal with an electric accident such as a power failure and the player is not disadvantaged. Further, by stopping the signal blocking means from accessing the storage means, it is possible to prevent adverse effects on the storage means due to the operating voltage dropping below a predetermined value. On the other hand, based on incorrect internal information,
Even if it returns to the state before the electric accident, it cannot be said that it will be suitable for the player's profit as a result. Therefore, it is possible to adopt the mode of using the internal information only when the management information for each storage area is correct. Become. The operation of the control means may be stopped when the signal blocking means stops accessing the storage means. Further, it is desirable that the control means includes an accident countermeasure circuit for coping with an electric accident.

Further, the control means, when the operating voltage is returned to a predetermined value or more and the management information for each storage area stored in the storage means before the operating voltage drops below the predetermined value, It is desirable to judge whether or not it matches the management information for each storage area read from the storage means. And
Each storage area depends on whether the management information for each storage area before the operating voltage drops below a predetermined value matches the management information for each storage area when the operating voltage returns to a predetermined value or more. It is possible to grasp whether or not the internal information is correctly stored for each case. That is, if the management information of each storage area matches before and after the change of the operating voltage, it can be understood that the internal information is correctly stored, whereas if the management information does not match before and after the change of the operating voltage. It can be understood that there is a high possibility that the internal information stored in the storage area in which the management information is not correctly stored is incorrect.

Further, when it is judged by the control means that the management information is not correctly stored, for each of the storage areas,
It is desirable to provide an automatic erasing means capable of automatically erasing the internal information stored in the storage means in which the management information is not correctly stored. Even if it returns to the state before the electric accident based on incorrect internal information, it cannot be said that it is in the interest of the player as a result, and if the management information is incorrect internal information, it is deleted. It is desirable to take such a measure. Further, the management information may be a check byte added to the internal information, or may be a checksum which is the total of the internal information. Specifically, when using the check byte, 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 the checksum, for example, when the internal information is “0001”, the sum “1H” is added to the internal information as the checksum, but the checksum changes according to the content 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, but when the amount of internal information increases, there is a disadvantage that it takes time to calculate the sum. On the other hand, in the case of a check byte, since it is fixed such as "55H", there are a check byte before the operating voltage drops below a predetermined value and a check byte when the operating voltage returns to above a predetermined value. While there is an advantage that it is easy to judge whether or not they match, if the contents of the check byte are known to an outsider, there is a disadvantage that fraudulent acts are likely to occur.

The storage area is divided into a special advantage information storage area in which information particularly advantageous to the player is stored and an advantage information storage area in which information advantageous to the player is stored. desirable. By dividing the special advantageous information storage area and the advantageous information storage area in this way, the internal information stored in the special advantageous information storage area can be read as much as possible to return to the state before the electric accident. it can. On the other hand, for the internal information stored in the advantageous information storage area, the storage area of the advantageous information storage area is secured to some extent,
By increasing the amount of data stored in the advantageous information storage area, the capacity required for storing the checksum is reduced, which is advantageous information for the player, but is more advantageous than the special advantage information in the state before the electric accident. Lower the degree of return. Specifically, the information stored in the special advantageous information storage area may be, for example, "big hit information," while the information stored in the advantageous information storage area may be, for example, "5 prize balls." There is information about the number of winning prizes, etc.

Further, it is desirable to provide an erasing means for erasing the internal information stored in the storage means. This is because the manager of the pachinko gaming shop may want to erase the internal information or the like stored in the storage means for management purposes, and by operating the erasing means, such a request can be easily met. Specifically, if the internal information stored in the storage means cannot be erased, for example, the internal information causes an electric accident in a state advantageous to the player (for example, a big hit), and the game cannot wait until the electric accident is repaired. As a pachinko amusement shop, after compensation for the electric accident, another player who is trying to play a game after completing the repair of the electric accident is in an advantageous state for the player even though he has not played any game. This is because, if appears suddenly, the disadvantage of the pachinko game store is great, and 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 preferably a erasing operation switch, and is preferably provided on the back side of the pachinko machine so as not to be easily touched by a pachinko game shop customer or the like. Further, it is desirable that the erasing means is a switch that is interlocked with the opening of the front door of the pachinko machine. In this case, when the pachinko game shop manager opens the front door of the pachinko machine when the operating voltage is cut off, the switch interlocks with the opening of the front door and the internal information stored in the storage means. Erase. As a result, the manager of the pachinko game shop can very easily meet the desire to administratively delete the internal information and the like.

It is preferable that the erasing means is provided with a time setting means for setting a supply time of the backup voltage, and the internal information stored in the storage means is erased after the supply time elapses. . As a result, the time setting means sets the backup voltage supply time (for example, 3 hours), and when the supply time (for example, 3 hours) has elapsed, the internal information stored in the storage means is erased.
This means that if it takes, for example, 3 hours or more to repair an electrical accident such as a power outage, it is unlikely that the customer who was at the pachinko gaming store would have been waiting for the repair for 3 hours. This is because the internal information stored in the storage means is unnecessary in such a case since the above may have already ended. In such a case, when the supply time (for example, 3 hours) elapses, the internal information stored in the storage means is automatically deleted. There is no need to do any work to erase.

Lights up.

The CPU 84A of the prize ball control board 55
When the drive signal of the payout solenoid 61 is input from the main board 53 via the input circuit 84D, the drive solenoid 61 is turned on / off for a predetermined time based on the drive signal of the payout solenoid 61. The main processing of the prize ball payout control processing performed in the CPU 83A of the main board 53 is each winning opening 18, 23, 24, 25, 26, 29, 3.
When a winning of 0 is detected, each winning opening 18, 23, 2
R for winning number data for every 4, 25, 26, 29, 30

The data of the number of winning prizes of 5, 26, 29 and 30 is accompanied by the payout of the prize balls, and the CPU 83A sets the data of the number of winning prizes to R.
Read from AM83C, and from the data of the number of winning prizes, 1
Is subtracted, and the data of the subtracted winning number is again stored in the RAM.
The winning subtraction process to be stored in 83C is executed.

Further, the CPU 83A has received a pachinko ball in the special winning opening 26 and is inputting a pachinko ball detection signal from the special winning opening count switch 26B, or a V zone in the central portion of the special winning opening 26. When it is detected that a pachinko ball has won a prize and the pachinko ball detection signal is input from the V switch 26A, the data of the number of winning a prize holes as the information on the number of winning a prize holes is read from the RAM 83C. Then, the CPU 83A performs a special winning opening winning process in which 1 is added to the data of the special winning opening winning number and the added data of the added special winning opening winning number is stored in the RAM 83C. On the contrary, when paying out the prize balls, the CPU 8
3A reads out the data of the number of big winning award winning prizes from the RAM 83C, subtracts 1 from the data of the number of winning award winning special winnings, and again subtracts the data of the number of award winning special winnings from RA.
The special winning opening winning subtraction process to be stored in M83C is executed.

Further, the CPU 83A has a first type starting port 23.
When it is detected that a pachinko ball has won a prize and a pachinko ball detection signal is input from the starting opening switch 23A, the RAM is detected.
The data of the winning number of the starting opening is read out from 83C. Then, the CPU 83A adds 1 to the data of the number of winning openings for the starting opening, and again adds the data of the number of winning openings for the starting opening to the RAM.
The first-type starting mouth winning process to be stored in 83C is performed. On the other hand, when paying out the prize balls, the CPU 83A reads the data of the number of winning openings for starting openings from the RAM 83C, subtracts 1 from the data of the number of winning openings for starting openings, and again the data of the number of winning openings for winning openings RAM83C. First to remember
The seed starting mouth winning / subtracting process is executed. Information about games and prize balls, such as the data of the number of winning pieces for the winning opening, the data of the number of winning pieces for winning, the data of the number of winning pieces for the large winning opening, etc. becomes the internal information stored in the RAM 83C, and the internal information causes an electric accident during the game. However, if it is erased from the RAM 83C and the state before the electric accident is not restored after the electric accident is recovered, the disadvantage to the player becomes extremely large. However, the accident countermeasure circuit 8 described later
By 3F, the internal information is stored / saved in the RAM 83C, and when the internal information is read by the CPU 83A, the state before the electric accident can be restored.

In this case, the storage area of the RAM 83C is a special advantageous information storage area 83C1 (see FIG. 5) in which information that is particularly advantageous to the player is stored, and information that is advantageous to the player is advantageously stored. Information storage area 83C
It is desirable to be divided into two. RAM8 like this
By dividing the storage area of 3C into the special advantageous information storage area 83C1 and the advantageous information storage area 83C2, the internal information stored in the special advantageous information storage area 83C1 can be read as much as possible, and the internal information before the electric accident can be read. Be able to return to the state. On the other hand,
The internal information stored in the advantageous information storage area 83C2 is information that is advantageous to the player, but the degree of returning to the state before the electric accident is lower than the special advantage information. Specifically, the size of the storage area of the special advantageous information storage area 83C1 is made as small as possible to reduce the amount of data to be stored, thereby reducing the occurrence of an error in the checksum. On the other hand, the storage area of the advantageous information storage area 83C2 is secured to some extent, and the amount of data stored in the advantageous information storage area 83C2 is increased to reduce the capacity required for storing the checksum. Then, the special advantageous information storage area 83
The information stored in C1 is, for example, "big hit information or information on the number of winning prizes for which 13 prize balls are paid out".
On the other hand, the information stored in the advantageous information storage area 83C2 is, for example, "information on the number of winning prizes for which five prize balls are paid out, etc.". In addition, the storage area is 3 more
You may subdivide into more than one piece.

Next, an accident countermeasure circuit 83F for coping with an electric accident will be described with reference to FIG. Figure 5
Is composed of an accident countermeasure circuit 83F and an extracted main part of the circuit of the main board 53. The accident countermeasure circuit 83F
A power supply monitoring circuit 83G for monitoring a voltage for operating the CPU 83A and the like provided on the main board 53, and a RAM 83
Signal blocking circuit 83H for preventing access to C, and CP
Decoder 8 for selecting a predetermined RAM 83C from U83A
3J and an erasing operation switch 8 as erasing means for erasing the game state information and the like stored in the RAM 83C.
It has 3K and so on. Also, the accident countermeasure circuit 83F
A backup power supply substrate 83L, which is different from the main substrate 53, is provided to be connectable therewith. The backup power supply board 83L is provided with a large capacity capacitor C1 as a backup power supply, and the connector C2 connected to the large capacity capacitor C1 is a connector C on the main board 53 side.
It is configured so that it can be connected to and disconnected from 3. The connector C
The reason for connecting and disconnecting between 2 and C3 is
When the connector C2 of the backup power supply board 83L and the connector C3 on the main board 53 side are disconnected, the RAM 83C
Since the internal information stored in is deleted, the RAM8
Without the internal information stored in 3C being decrypted,
This is because it is possible to prevent fraud. Also, the manager of the pachinko parlor can easily erase the internal information stored in the RAM 83C by disconnecting the connector C2 and the connector C3.

When the connectors C2 and C3 are connected to each other, the charges stored in the large-capacity capacitor C1 cause the terminals GND and RAM83C of the RAM83C.
A backup voltage can be supplied between the terminal Vcc and the terminal Vcc.
Further, since the operating voltage is applied to the terminal Vcc of the RAM83C via the diode D1, the operating voltage (for example, 5 volts) is normally the terminal GND of the RAM83C.
And the terminal Vcc are applied, and the backup voltage by the large capacity capacitor C1 is applied only when the operating voltage drops to a predetermined voltage value (for example, 4 V or less). In this case, normally, the operating voltage (for example, 5 V) is supplied to the large-capacity capacitor C1 via the diode D1.
Since the large capacity capacitor C1 is charged, 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 of the operation of the pachinko machine related to the accident countermeasure according to the embodiment. The power supply monitoring circuit 83G that functions as a detection unit that detects the operating voltage is
Terminal GND of RAM83C and terminal Vcc of RAM83C
The operating voltage applied between and is monitored, and it is determined whether the operating voltage is at the time of voltage drop (for example, 5 V or less) (S1). When the operating voltage is a predetermined voltage value (for example, 5 volts) or more (S1: NO), the CPU
83A RA internal information about games or prize balls
The memory areas 83C1 and 83C2 of the M83C are stored for each (S2), and an operation such as payment of a prize ball based on the internal information is executed (S3). And CPU83A is RAM
It is determined whether or not the operation based on the internal information stored in 83C is completed (S4), and when the operation is completed (S4:
If YES, the internal information is erased (S5). When 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, so the data for that winning is erased from the storage areas 83C1 and 83C2 of 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 V or less) (S
1: YES), in order to prevent access from the CPU 83A to the RAM 83C, a signal indicating a decrease in operating voltage (hereinafter referred to as a voltage decrease signal) is output from the monitoring output terminal K1 to the signal cutoff circuit 83H and the CPU 83A (S6). .
CPU83A which received the voltage drop signal, RAM83
When the internal information stored in the storage areas 83C1 and 83C2 of C is, for example, data of “0001” and “0011”, a tick sum (for example, “1H”, “3H”) is added as management information at the end of the data. Data) is added and stored (S7). After that, the CPU 83A itself is reset (S8). Then, the signal cutoff circuit 83H that has received the voltage drop signal performs a signal cutoff operation (S9), and the RAM 83C from the CPU 83A via the decoder 83J.
The access to the circuit is blocked by the signal blocking circuit 83H.

It is possible that the CPU 83A malfunctions when the operating voltage drops to a predetermined voltage value (for example, 4 V or less), and the RAM 83C is adversely affected. Is CP
This is because the signal from the U83A to the RAM 83C is cut off, so that the adverse effect due to the malfunction is prevented. And
Even when the operating voltage drops to a predetermined voltage value, the diode D1 allows the terminals GND and R of the RAM 83C to be connected.
Between the terminal Vcc of AM83C and the large capacity capacitor C
Since the backup voltage is supplied from 1 (S10), R
The internal information stored in the AM83C is saved.

After that, the power supply monitoring circuit 83G operates in the RAM 8
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 voltage of the operating voltage has dropped (S11). When the electric accident is not repaired (S11: NO), S9 and S10 are repeated. After that, when the electrical accident is repaired and the operating voltage lowered to a predetermined value or lower returns to a predetermined value or higher (for example, 5 volts) (S11: YES), the voltage drop signal from the monitoring output terminal K1 indicates the CPU 83A and the signal cutoff circuit 83H. Is no longer output (S12). Thereby, CPU83A
Reset is released and the signal cutoff circuit 83H
Stop the signal cutoff operation of the
Access from PU83A to RAM83C is permitted.

When the operating voltage returns to the predetermined value or more in this way, since the internal information and the tick sum are stored in the RAM 83C, the CPU 83A reads the tick sum stored in the storage areas 83C1 and 83C2 of the RAM 83C ( S13). At that time, the CPU 83A determines that the RA
It is determined whether the tick sums "1H" and "3H" added to the end of the internal information "0001" and "0011" stored in the storage areas 83C1 and 83C2 of the M83C are correct (S14). That is, the tick sum (management information) stored in the RAM 83C before the operating voltage drops below a predetermined value, and the tick sum (management information) read from the RAM 83C when the operating voltage returns to a predetermined value or above. ) And whether or not it matches. This is because when the operating voltage returns to above the specified value, the RAM
Before the tic sum (“1H” of “0001”) read from the storage area 83C1 of 83C becomes “2H” and the operating voltage drops below a predetermined value, the RAM 8
This is because it may not match the tick sum stored in 3C.

Then, only when the data of the tick sum is correctly stored (tic sum "3H") (S1
4: YES), the CPU 83A reads the internal information "0011" (S15), and returns to the state before the electric accident (S).
16), execute the operation corresponding to the internal information. As a result, an electric accident such as a power failure occurred during the game by the 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,
Since internal information etc. can be stored and saved in the RAM 83C,
After the repair of the electric accident, the game state before the electric accident can be returned to, and it becomes possible to deal with the electric accident such as a power failure, so that the player is not disadvantaged.

On the other hand, when an electric accident occurs during the game, the backup voltage is applied to the RAM 83C to store and store the internal information and the tic sum, but the tic sum data does not remain correctly (for example, the above-mentioned. "2H")
(S14: NO), when the electric accident is repaired, the CPU8
Even if 3A reads the internal information “0001”, it cannot always return to the state before the electric accident, so the internal information “0001” is automatically deleted (S17). By using the management information of such a tick sum, when the management information is correct, it can be known that the internal information is stored correctly, and when the management information is not correct, the RAM 83 is stored.
It can be understood that the internal information stored in C is likely to be incorrect. And, in the case of incorrect inside information, even if it returns to the state before the electric accident based on it, it cannot be said that it is in the interest of the player as a result, so if it is incorrect inside information, erase it. It is desirable to take measures such as Therefore, it is possible to adopt a mode in which the internal information is used only when the management information is correct.

The recording area 83C of the RAM 83C
As the automatic erasing means for automatically erasing the internal information stored in No. 1, 83C2, the recording area 8 of the RAM 83C is used.
Internal information stored in 3C1 and 83C2 is shown in FIG.
As shown in (a), as an example, “1010.
In the case of the data of “1101”, the CPU 83A executes the process shown in FIG.
As shown in (b), "0000 ... 000000"
Like the data of, overwrite and clear. However, it is not always necessary to use a checksum as the management information, and for example, a check byte that is the total of internal information may be used. When using the check byte, for example, “55H” is added to the internal information. Since the check byte is fixed like "55H", the check byte "55" before the operating voltage drops below a predetermined value.
It has an advantage that it is easy to determine whether or not it matches the check byte when the "H" and the operating voltage have returned to a predetermined value or more, whereas if it is known to an outsider, fraud is likely to occur. There are disadvantages.

On the other hand, since the checksum changes according to the internal information, there is an advantage that fraudulent acts can be prevented. However, if the amount of internal information increases, there is a disadvantage that it takes time to calculate the sum. In addition, RAM8
Since the erase operation switch 83K capable of interrupting the backup voltage is provided in the wiring connected to the terminal Vcc of 3C, the manager of the pachinko gaming shop, etc.
The internal information stored in the RAM 83C can be erased by operating the erase operation switch 83K to cut off the supply of the backup voltage.

When the manager of the pachinko gaming shop operates the erasing operation switch 83K in this way, the internal information stored in the RAM 83C is erased, so that the pachinko gaming shop manages the internal information stored in the RAM 83C. The demand for upper erasure can be met very easily. This is because the electric accident occurred just before the end of business hours and the RAM
If the information on the game state stored and stored in 83C is in a state advantageous to the player (for example, a big hit), the player is not playing any game when the game store is opened the next day after the electric accident is repaired. Nevertheless, if a favorable state for the player suddenly appears, the disadvantage of the game store is great, and it is necessary to erase the internal information stored in the RAM 83C to prevent such a situation. 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, and the signal cutoff circuit is the RAM 83.
Instead of connecting to the terminal CE of C, the terminal WR of the RAM 83C may be connected. Further, as a means for erasing the internal information stored in the RAM 83C, as shown in FIG. 7, a timer circuit T1 may be provided as a time setting means for setting the supply time of the backup voltage.

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 coupled to the base terminal of the transistor T2, and the emitter terminal of the transistor T2 and the timer circuit T1 operate. The application voltage and the backup voltage by the large capacity capacitor C1 are applied. After the backup voltage supply time (for example, 3 hours) has elapsed, the timer circuit T
When 1 operates to reduce the output to the base terminal of the transistor T2, the transistor T2 is deactivated, 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 backup voltage supply time (for example, 3 hours) elapses in this manner, the internal information stored in the RAM 83C is automatically erased, so that the manager of the pachinko game store stores the RAM 83C in the RAM 83C. It is not necessary to perform the work for erasing the stored internal information. 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, erase switch 83K
As shown in FIG. 9, the switch contact a and its operating piece b are
It is also possible to use a switch (not shown) that is turned on / off by contact / non-contact with.

As a concrete mode, when the operating piece b is pressed with the glass door 9 closed, the pressed operating piece b and the switch contact a are brought into contact with each other, and the erasing switch 83K is turned on. On the other hand, since the operating piece b is not pressed when the glass door 9 is opened, the operating piece b and the switch contact a are brought into a non-contact state and the erasing switch 83K is turned off. The erasing switch 83K is attached near the glass door 9.

Then, the pachinko game shop manager or the like turns the glass door 9 of the pachinko machine 1 in a state in which the power supply for operation is turned off.
When the switch is opened, the operating piece b of the erasing switch 83K is interlocked with the opening of the glass door 9 to turn off the erasing switch 83K, and the output signal from the erasing switch 83K is supplied under the supply of the backup voltage. CPU83 detected
A is configured to erase the internal information stored in the RAM 83C. As a result, by opening the glass door 9 of the pachinko machine 1 with the power supply for operation turned off, the manager of the pachinko gaming shop can easily erase the internal information and the like stored in the RAM 83C. .

The CPU 83 provided on the main board 53
A, ROM 83B, RAM 83C, input circuit 83D, output circuit 83E, and CP provided on the prize ball control board 55.
U84A, ROM84B, RAM84C, input circuit 84
The D and output circuit 84E form a control means. Further, the respective winning opening switches 18A, 29A, 30A, the respective lower winning opening switches 24A, 25A, the starting opening switch 23A, the V switch 26A, and the special winning opening counting switch 26B constitute winning detection means. Further, the RAM 83 of the main board 53
C functions as a 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 RAM 83C capable of storing internal information regarding payout status
When the power supply monitoring circuit 83G detects that the operating voltage has dropped below a predetermined value, the RAM 83C supplies the backup voltage from the large-capacity capacitor C1 to the RAM 83C.
The pachinko machine 1 capable of storing the internal information stored in the 83C, the internal information including the RAM 8
A check byte (management information) for managing whether or not the internal information stored in 3C is correctly stored is added, and when the operating voltage drops below a predetermined value,
A signal cutoff circuit 83H that stops accessing the RAM 83C, and when the operating voltage returns to a predetermined value or higher, access is enabled through the signal cutoff circuit 83H, and RA
The CPU 83A is provided which is capable of reading the internal information stored in the M83C and returning it to the state before the operating voltage drops below a predetermined value. In addition, the signal cutoff circuit 83H
When the CPU stops accessing the RAM 83C, the operation of the CPU 83A (control means) may be stopped as necessary.

As a result, when the power supply monitoring circuit 83G detects the operating voltage of the pachinko machine 1 and detects that the operating voltage has dropped to a predetermined value or less, the backup voltage is supplied from the large-capacity capacitor C1 to the RAM 83C. And then R
The internal information stored in the storage areas 83C1 and 83C2 of the AM 83C is saved and the signal cutoff circuit 83
H stops accessing the RAM 83C. When the power supply monitoring circuit 83G detects that the operating voltage has dropped to a predetermined value or less and then returned to the predetermined value or more, the power supply monitoring circuit 83G stops the signal interruption operation, and the CPU 83A causes the RAM to operate.
It is possible to allow access to 83C and read the internal information stored in the RAM 83C. In this case, since the checksum (management information) is added to the internal information of the storage areas 83C1 and 83C2, it is possible to know whether or not the management information is correctly stored. Only when the checksum (management information) is correct, the internal information can be stored. Information can be read and returned to the gaming state before the operating voltage dropped below a predetermined value, whereas if the checksum (management information) is incorrect, the internal information is automatically erased. You can

The present invention is not limited to the above-mentioned embodiment, and it is needless to say that various improvements and modifications can be made without departing from the gist of the present invention. Good. The backup power supply that supplies the backup voltage may be, for example, a battery such as a storage battery, a nickel-cadmium battery, a dry battery, or a nickel hydrogen battery.
Further, as the storage means for storing the information on the gaming state, for example, it is not always necessary to store and save in the RAM 83C that is normally used, and internal information may be transferred from the RAM 83C to, for example, a backup memory and stored and stored therein. 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 type 1 pachinko machine, but may be applied to, for example, the type 2 pachinko machine and the type 3 pachinko machine. Further, as a memory for storing and storing internal information and the like, a RAM 83 that is normally used
A transfer memory other than C may be used to transfer internal information and the like from the RAM 83C that is normally used immediately before saving to the transfer memory. Further, instead of providing the erasing operation switch 83K for each pachinko machine, a plurality of pachinko machines may be collectively operated so that one erasing operation switch can be operated.

As described above, according to the pachinko machine according to the present invention, an electric accident occurs, for example, even in a game state such as opening of a special winning opening as a jackpot during a game. Since internal information such as jackpot information can be divided into a plurality of storage areas to be stored and saved, the internal information stored in the storage means after electric accident repair can be read out under the control of the management information. It is possible to return to the state before the electric accident, and it is possible to deal with the electric accident, so that no disadvantage is given to the player. Particularly, when the control unit determines that the management information is not correctly stored for each of the storage areas, the internal information stored in the storage area where the management information is not correctly stored is automatically deleted. Since the automatic erasing means that can be performed is provided, erroneous internal information can be erased to prevent reading of the internal information stored in the storage area after the electric accident repair. And
Since the management information for managing whether the internal information stored in the storage means is stored correctly is added to the internal information for each storage area, whether the internal information is stored correctly or not Can be managed. Further, since the signal cut-off means stops accessing the storage means, it is possible to prevent an adverse effect on the storage means due to the operating voltage falling 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 the storage information when the operating voltage returns to the predetermined value or above. When determining whether the management information matches the stored 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 of the operating voltage, it can be understood that the internal information is correctly stored, whereas when the management information does not match before and after the change of the operating voltage, the internal information is stored in the storage means. It is possible to grasp that the internal information has a high possibility of being wrong, and it is possible to easily judge whether or not the internal information is correctly stored.

Further, when the control means determines that the internal information is not correctly stored, the internal information stored in the storage means may be automatically erased. It is possible to prevent the reading of the internal information stored in the storage means after the electrical accident repair by deleting the existing internal information. When using the check byte as the management information, it is easy to determine whether the check byte before the operating voltage drops below the specified value matches the check byte when the operating voltage returns above the specified value. Is. When using checksum as management information, it changes according to internal information.
You can prevent cheating. Further, when the storage area is divided into a special advantageous information storage area and an advantageous information storage area, regarding the internal information stored in the special advantageous information storage area,
While it is possible to return to the state before the electric accident by reading as much as possible, the internal information stored in the advantageous information storage area is advantageous information for the player, but is more advantageous than special advantageous information. , The degree of returning to the state before the electric accident is reduced, the storage area of the advantageous information storage area is secured to some extent, the amount of data stored in the advantageous information storage area is increased, and the capacity required for storing the management information is increased. Can be reduced.

When the erasing means for erasing the internal information stored in the storage means is provided, the internal information stored in the storage means is erased by the operation of the erasing means, and as a result, the manager of the pachinko amusement arcade stores the internal information. It is possible to very easily meet the demand for erasing internal information and the like for management. In addition, when the erasing means is a switch that operates in conjunction with the opening of the front door of the pachinko machine when the operating voltage is cut off, the manager of the pachinko game store, etc. When the switch is opened, the switch interlocks with the opening of the front door, and as a result, the internal information stored in the storage means is erased. As a result, the manager of the pachinko amusement store requests that the internal information etc. be deleted administratively. It can be adapted very easily. Further, the erasing means is provided with time setting means for setting the supply time of the backup voltage,
If the internal information stored in the storage means is automatically deleted after the supply time (for example, 3 hours), the manager of the pachinko game store deletes the internal information stored in the storage means. There is no need to do the work.
