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.

[0005] The present invention has been made to solve the above-mentioned problem. Even when an electric accident occurs during a game, the game information and the like are stored and saved, so that the information before the electric accident is stored. Because you can return to the game state of
It is possible to respond to electrical accidents such as power outages ,

As a result, even if an electrical accident such as a power failure occurs during a game played by a player, for example, in a game state such as opening of a winning port as a jackpot during the game, the game information or the like is stored. By saving the game state, 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. 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.

[0012] In the above-described pachinko machine, it is desirable that the game information includes probability fluctuation state information indicating a probability fluctuation state. In pachinko machines, there is a variable symbol display device for changing the symbol display, and a start winning port for starting the change of the symbol are arranged in the game area. When the symbol is stopped in a predetermined mode after the change (for example, "7, 7, 7"), a special game state advantageous to the player is generated. The probability of occurrence of this special game state may occur at a higher probability than the normal probability or may fluctuate between game states occurring at the normal probability, and this is referred to as probability variation. still,
It is called special game information indicating that it is in the state of special game,
This is also desirably included in the game information. If the probability that the special game state occurs is higher than the normal probability, it is an advantageous state for the player,
When an electrical accident such as a power failure occurs and the power is restored, the state is desirably continued, and the probability variation state information is desirably stored and stored in the storage means.

[0013] In the pachinko machine described above,
It is preferable that the game information includes fluctuation time state reduction information indicating a fluctuation time reduction state. This fluctuation time shortening state means that the fluctuation pattern of the losing pattern of the symbol fluctuation display device is normally stopped after being fluctuated for a predetermined time (for example, 6 to 8 seconds), whereas the symbol fluctuation display device is in the stopped state. The change pattern of the losing pattern of the normal time (for example, 6 to 8)
(Second), the waiting state (fluctuation time) until the state becomes the stop state and the “big hit (special game) state” is reduced (about 1/3). ). Also in this case, normally, the changing pattern of the losing pattern is set to change for a predetermined time (for example, 6 to 8 seconds), and under a specific condition (for example, when the changing pattern stops in a specific mode after the change). Below, a short time (2-
(3 seconds), then stop. And
If the symbol fluctuates for a short period of time (2 to 3 seconds), the next big hit is consequently accelerated, and the fluctuation time shortened state is advantageous for the player, so that an electric accident such as a power failure occurs and recovery is performed. In this case, it is desirable that the fluctuation time reduction state be continued, so that the fluctuation time reduction information is desirably stored in the storage means.

Preferably, the game information includes remaining time reduction count information indicating the remaining time reduction count. When the symbol of the variable symbol display device fluctuates, for example, when the player wins the first-class starting port or the like while the symbol of the variable symbol display device is fluctuating, the winning number is counted up to a predetermined number, and the variation time is reduced by the number of times. In the case of a pachinko machine that can transition to a state, it refers to the number of times that the pachinko machine can transition to the reduced fluctuation time state. Therefore, it is desirable that the fluctuation time reduction state information be stored in the storage means.

[0015] It is preferable that the game information includes normal symbol reservation number information indicating a normal symbol reservation number. In a pachinko machine in which a normal symbol display device for changing the symbol display and a gate or the like for starting the change of the normal symbol are arranged in the game area, the normal symbol display device is set based on the passage of the pachinko ball through the gate. When the game is stopped at a "predetermined number or the like" after the symbol fluctuates, the auxiliary prize winning device is opened for a predetermined time and a pachinko ball easily wins a predetermined starting port. The number of normal symbols that can be stopped by changing the number of symbols in the ordinary symbol display device by the number of passing symbols during the symbol fluctuation is called the ordinary symbol reserved number. It is desirable that the ordinary symbol holding number information is stored in the storage means.

It is preferable that the game information includes special symbol reservation number information indicating a special symbol reservation number. In a pachinko machine in which a special symbol display device for changing the symbol display and a start winning port for starting the change of the special symbol are arranged in the game area, a special symbol display device is provided based on the winning in the start port. Is stopped in a predetermined manner after the symbol fluctuates, and a special game state advantageous to the player is generated. The special symbol hold number information refers to the number of times that the number of winnings during the change of the special symbol can be shifted to the special game state, and it is desirable that the special symbol hold number information is stored and stored in the storage means.

Preferably, the game information includes round number information indicating the number of rounds of a jackpot. The round number information refers to information indicating how many rounds are currently present when a special winning opening repeats opening and closing operations by a predetermined number of rounds in the case of a jackpot. This round number information is desirably stored in the storage means.

It is preferable that the game information includes large winning opening winning number information indicating the number of winning winning openings. The large winning opening winning number information is information indicating how many pachinko balls have entered the large winning opening and how many have been won. It is desirable that the winning award winning number information be stored in the storage means.

The erasing switch provided on the main board is preferably provided on the back side of the pachinko machine in order to prevent the pachinko game shop customer from easily touching the switch . In some cases, the manager of the pachinko game store wants to erase the game information and the like stored in the storage means for management purposes.
By operating the switch, such a request can be easily satisfied.

If the game information or the like stored in the storage means cannot be erased, an electric accident occurs in a state in which the game information is advantageous to the player (for example, a jackpot), and the electric accident cannot be repaired. After compensating the player as a pachinko parlor, after the repair of the electric accident is completed, another player who tries to play the game has an advantage for the player even though they have not played any games yet. If the state suddenly appears, the disadvantage of the pachinko game store is great, so it is necessary to delete the game information and the like stored in the storage means to prevent such a situation.

The erasing switch is provided with time setting means for setting a supply time of the backup voltage. After the supply time has elapsed, the game information stored in the storage means is erased. desirable. 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 game 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 game information stored in the storage means is unnecessary. In such cases,
When the supply time (for example, 3 hours) elapses, the game information stored in the storage means is automatically deleted, so that the manager of the pachinko game store or the like can delete the game information stored in the storage means. You do not need to do the work. Also,
The erasing switch can erase the game information stored in the storage means by overwriting data “0”.

It is desirable that management information for managing whether or not the game information stored in the storage means is correctly stored is added to the game information. When such management information is added to the game information, it can be grasped whether or not the game information is correctly stored. That is,
If the management information is correct, it can be grasped that the game information is stored correctly. However, if the management information is not correct, the game information stored in the storage means is likely to be wrong.
Then, based on incorrect game information, even if the game state returns to the state before the electric accident, it cannot be said that as a result it is suitable for the player's interest, and if the game information is incorrect, it is necessary to delete it. It is desirable to take. Thus, it is possible to adopt a mode of using the game information only when the management information is correct.

Drive off. The main process of the prize ball payout control process performed by the CPU 83A of the main board 53 includes the winning ports 18, 2
When a winning in 3, 24, 25, 26, 29, 30 is detected, each winning opening 18, 23, 24, 25, 26, 29,
The winning number data is read from the RAM 83C every 30. Then, the CPU 83A adds 1 to the data of the winning number.
Is added, and the data of the added winning number is stored in the RAM again.
A winning addition process to be stored in 83C is executed. Conversely,
The data of the number of winnings in each of the winning ports 18, 23, 24, 25, 26, 29, 30 is sent to the CPU 8 in accordance with the payout of the prize balls.

Conversely, when paying out the prize balls, 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. The start port winning number data, the winning number data, the big winning port winning number data, and the like become the game information stored in the RAM 83C, and the game information is stored in the RAM 83C.
If the game information is stored and stored in the RAM 83C in a manner to be described later, the CPU 8
3A can return to the state before the electric accident by calling the game information.

Next, an accident countermeasure circuit 83F will be described with reference to FIG.
It will be described based on. FIG. 5 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 includes a C
A power supply monitoring circuit 83G for monitoring a voltage for operating the PU 83A and the like, a signal cutoff circuit 83H for preventing access to the RAM 83C, and a predetermined RAM from the CPU 83A.
There is provided a decoder 83J for selecting the 83C, an erasing operation switch 83K or the like as erasing means for erasing game state information or the like stored in the RAM 83C. In addition, the main circuit board 53 and another backup power supply board 83L are provided in the accident countermeasure circuit 83F 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 C connected to the large-capacity capacitor C1.
Reference numeral 2 is configured to be connectable to and detachable from the connector C3 on the main board 53 side.

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.
And it is applied between the terminals Vcc, only when the operating voltage drops to a predetermined voltage value (e.g., 4 volts or less), so that the backup voltage by the large capacitance capacitor C1 is applied. In this case, the operating voltage (for example, 5 volts) is normally applied to the large-capacity capacitor C1 via the diode D1.
Because it is applied to a large-capacity capacitor C1 becomes charged state, the backup voltage of the large-capacitance capacitor C1 may be supplied for a predetermined time for RAM83C.

The power supply monitoring circuit 83G, which functions as detecting means for detecting the operating voltage, monitors the operating voltage applied between the terminal GND of the RAM 83C and the terminal Vcc of the RAM 83C, and monitors the operating voltage. When the voltage drops (for example, when the voltage is 4 volts or less), the CPU 83A sends the RAM
In order to prevent access to 83C, monitor output terminal K1
Outputs a signal (hereinafter referred to as a voltage drop signal) indicating a decrease in the operating voltage to the signal cutoff circuit 83H and the CPU 83A. Thereby, the CPU 83A that has received the voltage drop signal
Is reset, and the signal cutoff circuit 83H that has received the voltage drop signal performs a signal cutoff operation to cut off access to the RAM 83C from the CPU 83A via the decoder 83J by the signal cutoff circuit 83H.

As a result, when an electric accident occurs and the operating voltage drops to a predetermined voltage value (for example, 4 volts or less), the signal cutoff circuit 83H causes the CPU 83A to malfunction and adversely affects the RAM 83C. In addition to preventing the game information from being applied, a backup voltage is supplied from the large-capacity capacitor C1 between the terminal GND of the RAM 83C and the terminal Vcc of the RAM 83C, so that the game information stored in the RAM 83C can be stored. Thereafter, when the electrical accident is repaired and the operating voltage dropped below the predetermined value returns to above the predetermined value (for example, 5 volts),
The voltage drop signal is no longer output from the monitoring output terminal K1 to the CPU 83A and the signal cutoff circuit 83H. Thereby,
The reset of the CPU 83A is released, and the signal cutoff operation of the signal cutoff circuit 83H is stopped, so that the decoder 83
Access from the CPU 83A to the RAM 83C via J is permitted.

When the operating voltage returns to the predetermined value or more, the game information is stored in the RAM 83C. Therefore, the CPU 83A calls the game information stored in the RAM 83C, and the operating voltage is reduced to the predetermined value. It is possible to return to the game state before it decreased below. As a result, an electric accident such as a power outage 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 can be supplied and game information and the like can be stored and stored in the RAM 83C. It is possible to return to the state, and it is possible to respond to an electric accident such as a power failure, so that there is no disadvantage to the player.

The reason why the connection and disconnection between the connectors C2 and C3 is made possible is that the backup power supply board 83
When the L connector C2 and the connector C3 on the main board 53 are disconnected, the game information stored in the RAM 83C is erased, so that the game information stored in the RAM 83C is not decrypted, Can be prevented. In addition, the pachinko parlor manager can easily disconnect the connector C2 and the connector C3 to easily access the RAM 83C.
Can be deleted.

Further, since the erase operation switch 83K which can cut off the backup voltage is provided on the wiring connected to the terminal Vcc of the RAM 83C, the erase operation switch 83K is operated as needed to operate the backup voltage. By interrupting the supply, the game information stored in the RAM 83C can be erased. When the manager of the pachinko game store or the like operates the erasing operation switch 83K as erasing means, the game information stored in the RAM 83C is deleted.
A request to erase the game information and the like stored in C for management can be easily satisfied.

This is because, when the occurrence of the electric accident is immediately before the end of the business hours and the information on the game state stored and stored in the RAM 83C is in an advantageous state (for example, a jackpot) for the player, the electric accident has been repaired. At the opening of the game store on the following day, if the advantageous state for the player suddenly appears in spite of the player not playing any game, the disadvantage of the game store is large, so it is stored in the RAM 83C. This is because such game information needs to be erased to prevent such a situation. However, in the case of this embodiment, for example, a transistor may be used instead of the diode D1, and the signal cutoff circuit may be connected to the terminal WR of the RAM 83C instead of connecting to the terminal CE of the RAM 83C. Also, the backup power supply board 83L and the main board 5
It is not always necessary to use 3 as a separate substrate. Further, the erase operation switch 83K constitutes a stop means for stopping the supply of the backup voltage, but the stop means is not necessarily limited to that mode.

As means for erasing the game 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. Specifically, the RAM 83
The collector terminal of the transistor T2 is connected to the terminal Vcc of C, and the timer circuit T1 is connected to the base terminal of the transistor T2.
And an operation voltage and a backup voltage by the large-capacity capacitor C1 are applied to the emitter terminal of the transistor T2 and the timer circuit T1. When the timer circuit T1 operates to reduce the output to the base terminal of the transistor T2 after the supply time (for example, 3 hours) of the backup voltage has elapsed, the transistor T2 is in a non-operating state. to block the application of a deletes the game information stored in RAM83C.

When the supply time (for example, 3 hours) of the backup voltage elapses as described above, the game 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 played game information. Also,
As means for erasing the game information stored in the RAM 83C, the game information stored in the RAM 83C is
As shown in FIG. 8A, as an example, “1010.
If the data is "101101", the clearing means may be overwritten and cleared like the data of "0000 ... 000000" as shown in FIG. 8B. In this case, since the clearing means clears the game information stored in the RAM 83C as a result of clearing the game information stored in the RAM 83C, it is possible to extremely easily meet a request to delete the game information and the like in management. Can be.

If the game information stored in the RAM 83C is, for example, data of “1010... 101101”, a tick byte is added as management information at the end of the data, and for example, the data of “55H” Is added and stored. When an electric accident occurs during the game, the backup voltage is set to RA as described above.
M83C is applied to store and save game information and the like. When the electric accident is repaired, when the CPU 83A calls the game information and returns to the game state before the electric accident, the tick byte "55H" is used. Verify that the data remains correct. The reason for using the management information of such a tick byte is that if the management information is correct, it can be grasped that the game information is correctly stored, but if the management information is incorrect, the game information stored in the RAM 83C is Since it is highly likely that the game information is incorrect, even if the game state returns to the state before the electric accident based on the incorrect game information, it cannot be said that as a result it is suitable for the player's interest, and if the game information is incorrect, It is desirable to take measures such as erasing it. Thus, it is possible to adopt a mode of using the game information only when the management information is correct.

As an erasing means for erasing the game information stored in the RAM 83C, an erasing switch interlocked with the opening of the glass door 9 (front door) of the pachinko machine 1 when the operating voltage is cut off. You may. In this case, as the erasing switch 83K, as shown in FIG. 6, a switch (not shown) which is turned on / off by contact / non-contact between the switch contact a and its operating piece b may be used.
Specifically, when the operation piece b is pressed with the glass door 9 closed, the pressed operation piece b and the switch contact a are brought into contact with each other, and the erase switch 8
While 3K is turned on, the operating piece b is not pressed when the glass door 9 is opened, so that the operating piece b is not in contact with the switch contact a, and the erase switch 83
The erase switch 83K is mounted near the glass door 9 so that K is turned off.

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 delete the game 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 game 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 information relating to the game state 83C that can store the data, and a power supply monitoring circuit 83G
Detects that the operating voltage has dropped below a predetermined value, the pachinko machine 1 capable of supplying a backup voltage from the large-capacity capacitor C1 to the RAM 83C and storing the game information stored in the RAM 83C. When the operating voltage drops below a predetermined value, the RAM 8
Signal cutoff circuit 83H for stopping access to 3C
When the operating voltage returns to a predetermined value or higher, the access via the signal cutoff circuit 83H is enabled, and the RAM 83
A CPU 83A capable of retrieving the game information stored in C and returning to a game state before the operating voltage drops below a predetermined value, and an erase operation switch 83K for erasing the game information stored in the RAM 83C. And When the signal cutoff circuit 83H stops accessing the RAM 83C, the CPU 83A
The operation of (control means) may be stopped.

Thus, 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 game 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 game information stored in the AM83C is called up, and the game state is returned to the state before the operating voltage dropped below the predetermined value.
Then, by operating the erase operation switch 83K as necessary, the game state information and the like stored in the RAM 83C can be erased.

The present invention can be applied to a pachinko machine according to another embodiment shown in FIG. This pachinko machine is equipped with a normal symbol display device, a special symbol display device, etc., a probability variation state, a variation time state reduction state, a time reduction remaining number storage state, a normal symbol hold number storage mode, and a special symbol hold number storage. A game mode that attracts the player's interest, such as a mode, can be realized, but a description will be given focusing on differences from the above-described pachinko machine. Specifically, the special symbol display device 9 is provided substantially at the center of the game area 90 shown in FIG.
2, the special symbol display device 92 includes left, middle,
CRT or LC that displays a specific symbol divided into three on the right
D and the like. Also, the special symbol display device 92
Above this, a normal symbol display device 91 is provided.
In addition, immediately below the special symbol display device 92, a first starting port 9 is provided.
3, gates 94 and 95, and an auxiliary prize winning device 96 for a tulip-type accessory are provided. When a pachinko ball wins in the first starting port 93 or the second starting port 96a of the auxiliary prize device 96, a special symbol is displayed. The image display of the device 92 fluctuates.

The first starting port 93, the gates 94, 9
5, and below the auxiliary prize winning device 96, a special electric accessory having a special winning opening 97 is provided. The opening and closing door 98 of the special winning opening 97 achieves a predetermined state after the pachinko ball enters the first starting port 93 or the second starting port 96a and the symbol of the special symbol display device 92 changes (for example, “7”). ,
7,7 ”), and the big winning opening 9
Winning out of 7 is detected. When a pachinko ball enters the first starting port 93 or the like while the symbol of the special symbol display device 92 is changing, the number of winnings (special symbol holding number).
Only, the special symbol display device 92 fluctuates and stops.

In this case, up to four pieces of the special symbol reservation number data can be stored in the RAM 83C, and every time one prize is won, the special symbol reservation number data is read from the RAM 83C, and 1 is added to the special symbol reservation number data. The addition is stopped and the addition is stopped when the data of the number of reserved special symbols becomes four. Conversely, when the special symbol holding number data is 1 or more, and the special symbol display device 92 stops changing due to the symbol change, the special symbol holding number data is read from the RAM 83C, and 1 is subtracted from the special symbol holding number data. The special symbol display device 92 stops again after the special symbol display number 92 changes the data of the special symbol reservation number that has been subtracted until the special symbol reservation number data becomes zero. In the game area 90, four display lamps 92a and the like indicating the number of special symbols to be reserved are provided, and the number of special symbols to be reserved corresponds to the number of display lamps 92a. It is desirable to adopt a mode of notifying the user. When data indicating the number of display lamps 92a corresponding to the number of special symbols to be held is stored in the RAM 83C, the count value obtained when passing through the starting port 93 or the gate 94 or the like (that is, the special symbol display device). 92
After the symbol fluctuates, it is desirable to store, as the lighting information of the hold lamp, for example, a count value at the time of achieving a predetermined state such as “7, 7, 7”.

When a pachinko ball passes through the gates 94 and 95, the normal symbol display device 91 starts operating, and after the symbol of the ordinary symbol display device 91 fluctuates, stops at a predetermined symbol (normally, 1 and 7). Is displayed)
Then, the auxiliary winning device 96 is opened for a predetermined time and the second starting port 9 is opened.
Pachinko balls are more likely to win in 6a. When the pachinko balls pass through the gates 94, 95, etc., during the symbol change, the symbol design display device 91 changes the symbol by the number of the pachinko balls (the number of ordinary symbol reservations), and the symbol changes in a predetermined mode (for example, “7”). Eye) to stop.

In this case, up to four pieces of data of the number of ordinary symbols retained can be stored in the RAM 83C, and are read out from the RAM 83C every time one prize is won. And the addition is stopped when the data of the number of normally reserved symbols becomes four.
Conversely, when the data of the number of ordinary symbols retained is 1 or more, and the ordinary symbol display device 91 stops with the symbols fluctuating, the data of the number of ordinary symbols retained is read from the RAM 83C, and 1 is subtracted from the data of the ordinary symbol retained number. Then, the subtracted data of the number of retained ordinary symbols is stored in the RAM 83C again, and the ordinary symbol display device 91 is stopped after the symbol is changed until the data of the retained number of ordinary symbols becomes 0. It is to be noted that four display lamps 99 or the like indicating the number of ordinary symbols to be reserved are provided in the game area 90, and the number of ordinary symbols to be reserved is made to correspond to the number of display lamps 99. It is desirable to adopt a mode of notifying the user. Also, data indicating the number of display lamps 99 corresponding to the number of ordinary symbol reservations is stored in the RAM 8.
When stored in the 3C, the count value obtained when passing through the gate 94 or the like (that is, the ordinary symbol display device 91)
After the symbol fluctuates, it is desirable to store, as the lighting information of the holding lamp, a count value at the time of achieving a predetermined state, for example, an eye of “7”.

Next, the probability fluctuation will be described. When the special symbol display device 92 fluctuates and the stopped symbol is, for example, "7, 7, 7", a special game state advantageous to the player is generated, but special game data (special game data) indicating this special game state is displayed. Game information) is also stored in the RAM 83C. The probability variation means that the special game state occurs at a higher probability (for example, 10/199) than the normal probability (for example, 1/199), and the normal probability (for example, 1/199). Fluctuates between when it occurs. Specifically, when the pachinko ball enters the first starting port 93 or the second starting port 96a, the probability fluctuation state is determined by the CPU.
The “special game state occurrence number” 83A is stored in the ROM 83B, and the “variation number” is taken from a clock circuit (not shown) and stored in the RAM 83C.
It is determined whether or not matches. And CPU8
3A is “special game state occurrence number” and “variation numerical number”
If the symbol does not match, the probability that the special game state will occur is set to be the normal probability (for example, 1/199), and the special symbol display device 92 has a specific mode after the symbol is changed, “losing pattern”. To stop. CPU8
3A is "special game state occurrence number" and "variation numerical number"
Is determined to match, the probability that the special game state occurs is higher than the normal probability (for example, 10/1).
99), the special symbol display device 92
Are stopped in the specific mode “big hit pattern” after the change. If the probability of occurrence of such a special game state occurs with a higher probability than the normal probability, it is an advantageous state for the player, and the data indicating the probability fluctuation as the probability fluctuation state information is RAM83C as the game information.
Is desirably stored.

Next, the fluctuation time reduction state will be described. The fluctuation time shortening state is a normal state in which the fluctuation pattern of the “losing pattern” of the special symbol display device 92 fluctuates for a predetermined period of time (for example, 6 to 8 seconds) and then stops. The fluctuation pattern of the losing pattern of the symbol display device 92 fluctuates for a shorter time (2 to 3 seconds) than a normal time (for example, 6 to 8 seconds) and then stops.
It means that the waiting time (fluctuation time) until the “big hit (special game) state” can be reduced (to about 1/3). Also in this case, the first starting port 93 or the second starting port 96a
When the pachinko ball enters, the CPU 83A
B, and the “variation time shortening occurrence number” stored in B and taken in from a clock circuit (not shown).
It is determined whether or not the “variation numerical value number” stored in the “. When the "variation time shortening occurrence number" and the "variation numerical number" do not match, the symbol of the "losing pattern" of the special symbol display device 92 is varied for a predetermined time (for example, 6 to 8 seconds). On the other hand, if the symbols match, the pattern of the "losing pattern" is changed for a short time (2 to 3 seconds), and then the state is stopped.
If such a symbol fluctuates for a short time (2 to 3 seconds), the next big hit is consequently faster, and the fluctuating time shortened state is an advantageous state for the player. It is desirable that the data indicating the fluctuation time shortening state is stored in the RAM 83C as game information.

Next, the remaining time reduction number will be described.
The number of remaining time reductions is, for example, when a symbol is won in the first starting port 93 or the like while the symbol of the variable symbol display device 92 is fluctuating, the winning number is counted up to a predetermined number, and the number is changed by that number. This refers to the number of times that a transition can be made to the time reduction state. Since the fluctuation time reduction state is an advantageous state for the player, it is desirable that the data indicating the remaining time reduction number as the information on the remaining time reduction number be stored in the RAM 83C as the game information. The data of the number of remaining time reductions as the information on the number of remaining time reductions can be stored in the RAM 83C.
Each time a prize is won, 1 is added to the data of the remaining time reduction number, and the data of the remaining time reduction number is stored in the RAM 83C. Conversely, when the data of the number of remaining time reductions is 1 or more and the normal symbol display device 91 is stopped by changing the symbol, the data of the number of remaining time reductions is stored in the RAM
83C, 1 is subtracted from the data of the number of ordinary symbols reserved, and the subtracted data of the number of remaining time reductions is R again.
It is stored in the AM83C, and is repeated until the data of the remaining time reduction number becomes zero.
