DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables a big hit game state to appear based on a display result of a symbol display device displaying a big hit symbol, and the big hit symbol is displayed after a predetermined big hit game state is completed. The present invention relates to a pachinko machine equipped with a probability changing means for changing the appearance probability of a low probability to a high probability.

[0002]

2. Description of the Related Art Hitherto, a large number of pachinko machines have been provided to the market in which a large hit game state is developed based on the display result of a big hit symbol displayed on a symbol display device so that a large number of winning balls can be obtained in a short time. It had been. In such a pachinko machine, the appearance probability of the big hit symbol is constant (for example, 1
/ 200), there is a tendency that the appearance of the big hit symbols tends to be at a substantially constant cycle, and there is a problem that the game has no intonation and the player is easily bored. In order to solve such a problem, the present applicant has previously filed Japanese Patent Application No. Hei.
In the above item, a pachinko machine having a probability changing means for changing the appearance probability of a big hit symbol from a low probability to a high probability at the end of a right occurrence state (corresponding to a big hit game state) of a predetermined number of times is proposed. It is possible to give inflection feeling.

[0003]

By the way, in the above-mentioned pachinko machines, the big hit game states appear at relatively short intervals, so that each big hit game state and the high-probability display game state between them are displayed. Can be regarded as constituting one big jackpot gaming state, but conventionally, a gaming state in which the symbol display device is displayed with a high probability is regarded as a normal gaming state, and in particular, Was not reported or managed. The present invention
In view of the circumstances described above, the purpose is to notify the game state in which the symbol display device is controlled with high probability to be a big hit game state and to notify and manage the fact. It is to provide a pachinko machine that can perform.

By transmitting the signal derived in this way to, for example, a management computer, the payout rate during the period of the continuously occurring big hit gaming state can be calculated, or the continuously generated big hit gaming state can be calculated. The number of appearances can be known, and management data such as characteristics of the pachinko machine and business data can be obtained. Also, by transmitting the jackpot signal to a notification device provided on a pachinko machine, a pachinko island, or the like, the player is notified that the pachinko machine is in a jackpot game state or in a high probability game state. Alternatively, it can be notified to another player or a clerk at the game hall.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. First, the configuration of the game board 1 of the pachinko machine according to the embodiment will be described with reference to FIG. In the figure, a special winning device 4 is arranged substantially at the center of a game area 3 surrounded by a guide rail 2 of a game board 1.
The special prize winning device 4 has a plurality of passing areas 5, 6 a, 6 b including a special device operating area 5, turns a hit ball received from above using a spiral disk, and passes any one of the passing balls during the turning. It is to be dropped on the areas 5, 6a, 6b. The left and right passing areas 6a and 6b are configured as a winning passing area in which a predetermined number (for example, 15) of prize balls are discharged by dropping a hit ball. The special device operating area 5 at the center is guided downward as it is when the hit ball falls, so that the special winning opening 7 arranged below the special winning device 4 can be won. When a hit ball is won in the special winning opening 7, a predetermined number of prize balls are discharged in the same manner as described above, and the special winning ball detecting switch 24 (see FIG. 3) built in the special winning opening 7 is turned on. The ON signal of the special winning ball detection switch 24 is used as a signal for detecting occurrence and disappearance of the right generation state. In the illustrated embodiment, only the hit ball guided by the electric winning device 16 described later is guided to the special winning device 4.

Below the special winning device 4, a variable winning device 8 is arranged. This variable winning device 8
It has an attacker opening / closing plate 9 driven to be opened and closed by an attacker solenoid 29 (see FIG. 3), and receives a hit ball falling in the game area 3 with the attacker opening / closing plate 9 opened. However, the opening of the attacker opening / closing plate 9 is executed based on the fact that the right generation state is continued and a hit ball is won in the starting winning opening 11 described later, and one opening is performed by a predetermined number (for example, Until ten winning balls are generated, or for a certain period of time (for example, 9.7)
Seconds) has elapsed. In order to count the predetermined number, the variable winning device 8 is provided with a winning ball number detection switch 26 (see FIG. 3), and detects the number of winning balls detected by the winning ball number detecting switch 26. A winning number indicator 10 is built in for displaying.

[0008] Below the variable winning device 8, there is a starting winning opening 1
1 is provided. The start winning opening 11 is for opening the attacker opening / closing plate 9 based on the fact that the right generation state is continued as described above and a hit ball is won. Board 9
Therefore, when the attacker opening / closing plate 9 is open, it is difficult for a hit ball to win the starting winning opening 11. The starting winning opening 11 is provided with a starting winning ball detection switch 25 (see FIG. 3) for detecting a winning of a hit ball. Furthermore, during the right generation state, the starting winning opening 1
The number of balls that have won 1 is displayed on a start winning number display 17 provided on one side (the right side in the figure) of the special winning device 4. The start winning number display 17 indicates the number equal to the number of times the attacker opening / closing plate 9 is opened in many cases. When the numerical value displayed on the start winning number display 17 becomes 16, the right generation state ends. Note that the number of prize balls discharged by hitting the starting winning opening 11 with a hit ball is set to a smaller number (for example, seven) than the number of prize balls discharged by other winning holes.

[0009] Gate winning ports 12a and 12b are arranged substantially at the center and left and right of the game area 3, respectively. The gate winning ports 12a, 12b are not configured to discharge prize balls merely because a hit ball falling in the game area 3 passes therethrough, but the gate winning ports 12a, 12b.
This is expressed as a winning opening in the sense that the variable display of the symbol display device 13 provided on one side (the left side in the drawing) of the special winning device 4 is controlled by the passing of the hit ball through b. Of course, in this case, a winning opening from which a prize ball is discharged may be used. The gate winning ports 12a and 12b are provided with a gate winning ball detection switch 23 (see FIG. 3), and the symbol display device 13 performs variable display based on the detection signal.

The symbol display device 13 includes a plurality (two in the illustrated embodiment) of symbol indicators 14a and 14b (comprising 7-segment LEDs) and a gate winning memory display 15. I have. Symbol display 14a, 14b
Starts a fluctuating display based on the fact that a hit ball has been won in the gate winning openings 12a and 12b, and after a predetermined time (for example, 6 seconds) elapses, the left symbol display 14a stops, and then a slight time delay occurs. The right symbol display 14b is controlled to stop. Further, as the symbols displayed on the left symbol display 14a, for example, ten types of numeric symbols from 0 to 9 are variably displayed, and the right symbol display 1 is displayed.
The symbols displayed in 4b are, for example, 0-9, A, C,
Nineteen kinds of numbers and alphabetic symbols from E, F, H, J, L, P and U are displayed in a variable manner. And
When the combination of the symbols when both of the symbol indicators 14a, 14b are stopped is a combination of "3, 3" or "7, 7", it is determined that a big hit has occurred, and the electric winning device 16 described later is used.
Are driven to open. The symbol indicators 14a and 14b use two-color light emitting segment LEDs. For example, when the variable display is performed with a low probability, which will be described later, for example, the display is displayed in red, and when the variable display is performed with a high probability, For example, the display is controlled so that the display is changed to green. In this way, the player can immediately know at what probability the symbol display device 13 is variably displaying.

Further, the gate winning storage display 15 provided in the symbol display device 13 is provided with the gate winning opening 12a, 1
This informs that up to four hit balls that have passed through 2b have been stored. Even if the hit balls pass through the gate winning openings 12a and 12b with all four of the gate winning storage indicators 15 lit, it does not matter. Treated as invalid.

By the way, the symbol indicators 14a, 14b
When the combination at the time of stop becomes a winning symbol combination, the electric winning device 16 arranged above the special winning device 4 is opened for a predetermined time (for example, 6 seconds). The illustrated electric winning device 16 is a so-called tulip winning device, and includes a tulip solenoid 28 (see FIG. 3).
Is driven to open. Then
When the tulip solenoid 28 is excited and the electric winning device 16 is opened, the hit ball falling in the game area 3 is easily accepted, and the hit ball received by the electric winning device 16 is guided to the special winning device 4, and It falls into any of the above-mentioned passage areas 5, 6a and 6b. It should be noted that when one hit ball is won in the electric winning device 16, the tulip solenoid 28 is turned off and closed even before a certain time has elapsed. Further, in the illustrated electric winning device 16, an obstacle nail is provided so that a hit ball does not win at all when the electric winning device 16 is closed, but the electric winning device 16 is closed. At any time, a hit ball may be won.

Further, in addition to the above-described configuration, a plurality of winning ports 18, 19a, 19b, 2
0a, 20b, operation lamps 21a, 21b, and out port 2
2 are provided. Of these, the operation lamps 21a, 21
b mainly informs that the right is in the state of right generation, but a lamp group (not shown) that informs that the symbol display device 13 and the variable prize device 8 are being driven is provided by each prize device and the prize device. Mouth 19a, 19b, 20a, 20b
And so on.

The configuration of a control device for controlling the operations of the symbol display device 13, the special winning device 4, the variable winning device 8 and the like described above will be described with reference to FIG. FIG. 3 is a block diagram showing an electrical configuration of the control device. The control device uses a microcomputer 30. An external ROM 31 and an external RAM 34 are connected to the microcomputer 30. The ROM 31 has an outlier numerical value table 32 for determining numerical values to be displayed on the symbol displays 14a and 14b in the off mode shown in FIG. 7, and a symbol display 14a and 14b in the hit mode shown in FIG. A hit numerical value table 33 for determining a numerical value to be displayed is set.

The RAM 34 has a mode determination counter 35
An out-of-number memory 36 and an out-of-number memory 37 for storing values that change every moment by the out-of-number table 32 and the out-of-hit value table 33 are respectively formed. A memory 38 is formed. This confirmation memory 38
Has a memory for the number of reserved winning balls of the gate winning ports 12a and 12b + 1. The numerical value for mode determination for each retained winning prize ball is determined at the time of winning (passing), and the numerical value is stored in each determination memory 38. The maximum value of the mode determination counter 35 is changed to change the probability of occurrence of the hit mode.

On the other hand, a gate winning ball detection switch 23 for detecting passing balls in the gate winning ports 12a and 12b, a special winning ball detecting switch 24 for detecting a winning ball that has passed through the special device operating area 5, and a winning in the starting winning port 11. Start winning prize ball detecting switch 25 for detecting a ball, winning prize ball detecting switch 2 for detecting a winning ball on the attacker opening / closing plate 9
6 and a tulip detection switch 27 for detecting a winning ball in the electric winning device 16 are connected to the microcomputer 30 via a waveform shaping circuit 39 composed of a flip-flop for preventing chattering.

The clock generation circuit 41 outputs an external interrupt signal via the frequency divider 40 to the IN of the microcomputer 30.
Output to T terminal. Then, the microcomputer 30 executes the main program shown in FIGS. 4 to 6 in synchronization with the external interrupt signal. A timing signal output from the timing signal generation circuit 42 is input to the RST1 terminal of the microcomputer 30, and a numerical value generation program (not shown) is started in synchronization with the timing signal. A reset signal output from the reset signal generation circuit 43 by the ON operation of the power supply circuit 44 is input to the RST2 terminal of the microcomputer 30, and an initial program (not shown) is started by the reset signal.

A display driving circuit 45, a display selection circuit 46, an external connection terminal 47, and a driver 48 are connected to each output port of the microcomputer 30. The display drive circuit 45 and the display selection circuit 46 are connected to the above-described symbol displays 14a and 14b, the gate winning storage display 15, the winning number display 10, and the starting winning number display 17. These indicators are provided by the microcomputer 30
By outputting the selected data and display data at a fixed period, dynamic driving is performed. That is, each display unit is selected by the display selection circuit 46 and displayed according to the output signal of the display drive circuit 45 at that time. A jackpot signal is derived from the microcomputer 30 during the right generation state and during the display control of the symbol display device 13 with a high probability from the microcomputer 30. The external connection terminal 47 is connected to a management computer (not shown). Is connected, a big hit signal is given to the management computer. The driver 48 drives and controls the tulip solenoid 28, the attacker solenoid 29, the operation lamps 21a and 21b, the lamp indicators (not shown), and the lamp group in accordance with a signal from the microcomputer 30.

Next, the operation controlled by the above-described control device will be described with reference to a flowchart showing a processing procedure of the microcomputer 30. When the power supply circuit 44 is energized, power is supplied to the microcomputer 30 and
The reset signal generation circuit 43 outputs the reset signal to RST2
Output to terminal. Then, the microcomputer 30
(Hereinafter referred to as CPU 30) sets each register and counter to an initial value. After the initial setting, every time an external interrupt signal output from the frequency divider 40 is input, the CPU 3
0 executes the main program of FIGS. In FIG. 4, a timer updating process is performed in step 100, and in step 102, the state signals S1, S
2, S3, S4 and S5 are read. These status signals are configured by negative logic, and when the signal is at a low level, the switch is in the ON state, indicating that a winning ball has been detected.

When the falling of the gate winning signal S1 is detected in step 104, step 106
It is determined whether or not the number of pending winning balls is smaller than four. Only when the number is smaller, the gate winning counter C is determined in step 108.
Is updated by 1 and the value of the mode determination counter 35 at that time is stored in the determination memory M (c) 38 at step 110. That is, when there is no pending winning ball, the gate winning opening 12
When a prize is detected in a or 12b, the gate prize counter C becomes 1, and the value of the mode determination counter 35 at that time is stored in the determination memory M (1). When the gate winning counter C is 1 or more, the gate winning port 12 is further increased.
When the player wins a or 12b, the winning ball becomes a reserved winning ball, and the gate winning counter C is incremented by one. Then, the value of the mode determination counter 35 at the time of winning is stored in the determination memory M (c) corresponding to the held winning ball. In this way, when the winning in the gate winning openings 12a and 12b is achieved, the numerical value for determining the winning mode is determined.

In step 112, a special winning signal S2
Is detected, it is determined in step 114 whether or not the right generation flag has been set. If not, the right generation flag is set in step 116. As a result, a right is generated. Then, when the right is generated, step 11 is executed.
If it is determined in step 8 that the probability increase flag is set, the probability increase flag is reset in step 120, and the green flag is reset in order to indicate that the symbol displays 14a and 14b are to be displayed with a low probability. This allows
The symbol display displayed on the symbol indicators 14a and 14b is displayed in red, thereby informing the player that the probability that the symbol is displayed is low. Then, thereafter, in step 122, the operation number counter L is incremented by one. On the other hand, when it is determined in step 114 that the right occurrence flag has already been set, the special winning signal S2 is treated as a signal for extinguishing the right occurrence state, and the process proceeds to step 132 described later.

Next, at step 124, the starting winning signal S3
Is detected, it is determined in step 126 whether or not the right generation flag is set. If the right generation flag is not set, the following steps 128 to 136 are not performed. On the other hand, when the right occurrence flag is set, the start winning ball counter D is incremented by 1 in step 128, and thereafter, in step 1
At 30, it is determined whether the value of the starting winning ball counter D is greater than 15. If the value is greater than 15, the right generation flag is reset in step 132 to end the right generation state, and it is determined in step 134 whether the value of the operation counter L at that time is an odd number. When the value of the number-of-operations counter L is an odd number, step 136
At the same time, a green flag is set to indicate that the symbol displays 14a and 14b are to be changed with a high probability. As a result, the symbol displayed on the symbol indicators 14a and 14b is displayed in green, thereby notifying the player that the probability that the symbol is displayed is high.

Steps 112 to 122 described above
And Steps 132 to 136 are executed when the right generation state ends based on the passage of a hit ball to the special device operation area 5 and the predetermined number of hit balls to the starting winning opening 11 during the right generation state, and the end is an odd number. This indicates that the probability that the symbol display device 13 will be in the big hit mode at the end of the round increases, and that the probability increase state is resolved at the start of the next right generation state, and therefore, the right Since there is a tendency that a game state which is likely to be generated and a game state which is unlikely to be continuously generated are alternately generated, the game can be inflected, and the interest of the player can be attracted. Further, the change in the probability of the hit mode is indicated by the symbol indicators 14a and 14b.
Can be distinguished by the color of the variable display, so that the player can immediately know at what probability the symbol display device 13 is performing the variable display.

Further, in step 138, the winning ball number signal S4
Is detected, at step 140, the winning ball counter E is incremented by one. Step 1
When the falling of the tulip winning signal S5 is detected at 42, the value of the tulip winning counter B is set to 1 at step 144.

Next, steps 146 to 146 shown in FIGS.
174, 206 to 218 are performed in the symbol display device 1
3 and the processing steps corresponding to the respective states of the electric prize apparatus 16, and steps 176 to 204 and 206 to 218 are processing steps corresponding to the respective states of the variable prize apparatus 8 during the right generation state. And the symbol display device 13
And the processing steps of the electric winning device 16 are performed irrespective of whether or not the right is being generated.

First, processing steps corresponding to the states of the symbol display device 13 and the electric winning device 16 will be described. (A) Processing when there is no gate winning ball When there is no gate winning ball, that is, when the gate winning counter C is 0, steps 100 to 150 and 17 are performed.
6 to 218 are performed, whereby the symbol display 1
4a, 14b, a lamp group, and each solenoid perform predetermined display or driving, and if either the right generation flag or the probability increase flag is set, a big hit signal is derived.

(B) Variation display processing In step 150, the value of the counter C is determined. When a winning is detected, the value of the counter C is decremented by one, and the register F is set to 1 to indicate the variation display state. The timer T1 is set to a predetermined value (for example, 6 seconds) (steps 152, 1
54). Then, as the gate winning counter C is decremented in step 156, the contents of the determination memory M (c) 38 are incremented by one and updated. Then step 15
It is determined at 8 whether or not the timer T1 has timed out. If it is determined that the time has expired, at step 160, the hit mode is determined from the numerical value stored in the determination memory M (0). For example, when the value of the mode determination counter is “3”, it is determined that a hit has occurred, and when the value is any other value, it is determined that the hit has occurred. And step 1
When it is determined that it is not a hit after shifting to 62, the process shifts to step 164 and the value of each digit of the outlier numerical value memory 36 storing the display numerical value in the outlier mode is set in the numerical value display register. On the symbol display devices 14a and 14b, the numerical values for display in the off mode stored in the outlier value memory 36 are displayed when the fluctuation stops. On the other hand, if it is determined that a hit has occurred, the process proceeds to step 166, where the value of each digit of the hit numerical value memory 37 storing the display numerical value in the hit mode is set in the numerical display register. In 14a and 14b, the display numerical values in the hit mode stored in the hit numerical memory 37 are displayed when the fluctuation is stopped.

In this way, the symbol indicators 14a, 14
In b, a numerical value for display generated by a numerical value table for exclusive use and a numerical value table for hitting, which is different from the numerical value generating means for determining the mode, is displayed. Also,
Since the maximum value of the mode determination counter 35 is set to, for example, 80 when the probability is low and to 8 when the probability is high, the probability that the numerical value stored in the decision memory M (c) is a hit value is determined by the probability increase flag. Is set, 1 /
8, if the probability increase flag is not set, it is 1/80. Until the timer T1 times out, it is determined that the variable display is being performed in step 146. Therefore, steps 100 to 146, 158, and 176 are performed.
To 218 are repeated.

(C) Processing at the time of hitting If the result of the determination at step 162 is a hit, the tulip solenoid flag is set at step 168 to indicate that the tulip is being opened.
And a predetermined time (for example, 6 seconds) is set in the timer T2. The tulip solenoid 28 is energized until it is determined in step 170 that the timer T2 has timed out, or until it is determined in step 172 that the value of the tulip winning counter B is 1, so that the ball is hit. The state in which the electric winning device 16 easily wins is maintained. Thus, when the predetermined time has elapsed or when the value of the tulip winning counter B is set to 1, the tulip solenoid flag is reset in step 174, and the status register F and the tulip winning counter B are set to 0. As described above, when it is determined that a hit has occurred, the electric winning device 16 accepts one hit ball or opens the ball until a certain time elapses. Therefore, the possibility that the hit ball is guided to the special winning device 4 is increased. The likelihood that the hit ball passes through the special device operation area 5 to generate a right is also increased. Until the timer T2 times out or the value of the tulip winning counter B becomes 1, it is determined in step 148 that the opening is being performed, so that steps 100 to 148, 170, 172, and 17 are performed.
Steps 6 to 218 are repeated. In addition, the electric winning device 16
After the end of the open state, the symbol display device 13 may start the next variable display after a predetermined interval.

Next, the processing steps of the variable winning device 8 will be described. (D) Processing during the right generation state When it is determined in step 180 and step 182 that the value of the starting winning ball counter D is 1 or more and smaller than 17 and larger than the value of the opening counter G, the attacker solenoid is determined in step 184. The flag is set, and the status register H indicating that the attacker opening / closing plate 9 is being opened is set to 1. Thereafter, in step 186, the opening counter G is increased by 1. Then, in a step 188, a timer T3 for regulating the opening time of the attacker opening / closing plate 9 is set to a predetermined value (for example, 9.7 seconds).
Until it is determined that the time is up at 0 or step 192
Then, the attacker solenoid 29 is excited until the winning ball counter E reaches 10. Thereafter, when a predetermined time has elapsed or when the winning ball counter E reaches 10, the attacker solenoid flag is reset to release the excitation state of the attacker solenoid 29 in step 194, and the winning ball counter E is reset. Set to 0.

When one opening / closing state of the attacker opening / closing plate 9 is completed, an interval time is provided until the next opening / closing operation.
Steps 196 and 198 are performed. Then
If the interval time has elapsed, step 200
Sets the register H to 0, and determines whether or not the right generation flag is set at that time. If the right occurrence flag is set, the process immediately proceeds to step 206. If not, the value of the starting winning ball counter D and the number of open counters G is set to 0 in step 204, and the process proceeds to step 206. I do.

In steps 206 to 212, symbol displays 14a and 14b, a lamp display and a lamp group (not shown),
Tulip solenoid 28, attacker solenoid 2
9 is driven according to the state of the aforementioned flag or register. During the variable display of the symbol indicators 14a and 14b, the contents of the out-of-place numerical value table 32 are displayed in a variable manner at a speed that cannot be identified in order.

In the next steps 214 to 218, it is shown that the jackpot signal is derived from the microcomputer 30 to the external connection terminal 47 when either the right occurrence flag or the probability increase flag is set. Therefore, the jackpot signal is continuously derived during the right occurrence state and the subsequent gaming state at the time of high probability, and further during the right occurrence state appearing based on the high probability.

This state will be described with reference to the time chart of FIG. 1. After the power is turned on, the special device is turned off (right generation flag is set) from the point a where the special device is turned off (right generation flag is reset). Up to the point is the first right generation state. The probability of the big hit symbol appearing at this time is
The display is controlled with a low probability of 1/80. Then, during the period from the point b (the probability increase flag is set) at which the right occurrence state ends to the point c (reset of the probability increase flag) which is the start point of the second right occurrence state, the big hit symbol of the symbol display device 13 is displayed. The display probability is controlled with a high probability of 1/8. In addition, at point c, which is the second right generation state, although the probability is low, the special device is turned on and the state is continued up to point d. At the point d, the probability is not changed because the even-numbered right generation state ends. Since the right occurrence flag and the probability increase flag are set alternately from point a to point d, the big hit signal is ON from point a to point d. By transmitting the jackpot signal derived in this way to the management computer, the payout rate during the continuous jackpot gaming state can be calculated or the jackpot gaming state occurring continuously can be calculated. The number of times can be known, and management data such as characteristics of the pachinko machine and business data can be obtained. Also, by transmitting the jackpot signal to a notification lamp provided on a pachinko machine or a pachinko island other than the management computer, the pachinko machine is either in a jackpot gaming state or in a gaming state with a high probability. This can be notified to the player or another player or a clerk at the game hall. The third and fourth
The above-described operation is repeated in the right right generation state.

Although the embodiment has been described above, in the above embodiment, the segment LEDs are illustrated as the symbol displays 14a and 14b, but other displays may be used.
Also, numerical values of the high probability and the low probability may be arbitrarily set.
Also, the number of changes to the high probability is not only at the end of the odd number of times, but may be at the end of an arbitrary or random number, or even if the rights generation state based on the high probability continues a plurality of times. good. Further, in the above-described embodiment, the pachinko machine which is in the right occurrence state as the big hit game state is exemplified, but when the symbol display device displays the big hit symbol, the variable winning device is repeatedly driven in a predetermined mode,
A so-called digital pachinko machine may be used. Furthermore,
The starting point for deriving the big hit signal may be the time when the attacker opening / closing plate 9 is first opened. Alternatively, separate signals may be derived for the big hit game state and the high probability variation display game, and the separate signals may be processed by the management computer to determine one big hit game state as a whole.

[0036]

As is apparent from the above description, in the present invention, the game ends when the big hit game state occurs.
To derive the first signal and display the fluctuation with high probability
Since the second signal is configured to be continuously derived during the game , the derived signal is, for example,
By transmitting to the management computer, it is possible to calculate the payout rate during the period of the continuously occurring big hit gaming state, or to know the number of appearances of the continuously occurring big hit gaming state. And management data such as sales data. Also, by transmitting the jackpot signal to a notification device provided on a pachinko machine, a pachinko island, or the like, the player is notified that the pachinko machine is in a jackpot game state or in a high probability game state. Alternatively, it can be notified to another player or a clerk at the game hall.
