As a result, it is impossible for a person other than a specific person to change the setting value by the probability setting switch 57 described below, and it is possible to reliably prevent fraud by a store clerk at a game arcade.

A structure for changing the probability of occurrence of a specific game state, which is a main part of this embodiment, is housed in the opening / closing plate 55. That is, the probability setting switch 57 which constitutes a part of the probability setting means for changing the occurrence probability of the specific game state is provided. Probability setting switch 5
7 is a push button type. Therefore, every time the probability setting switch 57 is pressed, the occurrence probability of the specific game state is changed. In the case of this embodiment, as described later, the occurrence probability of the specific game state is set in five stages, and is sequentially changed every time the probability setting switch 57 is pressed. On one side of the probability setting switch 57, a current set value display 58 for displaying the current set probability is provided as set value display means.
a and next set value display 58b for displaying the next set probability
Are provided. The current set value display 58a displays the set probability before the probability setting switch 57 is operated, and the next set value display 58b displays the set probability after the probability set switch 57 is operated. ing.

The setting probability set by the probability setting switch 57 is displayed as described above.
While confirming at 58b, the probability setting operation can be reliably performed without error. In particular, in the present embodiment, even if the probability setting is changed by pressing the probability setting switch 57, Since the changed setting probability is reflected in the game after a certain period of time, the setting probability that is still continuing and the setting probability that is changed after the certain period has elapsed are displayed, and an erroneous operation is performed. To get rid of it.
When the probability setting operation means is not a push button type as in the embodiment but a lever with a scale, the next setting display 58b is not necessary.

On the other side of the probability setting switch 57,
A variable display number display 59 is provided. The variable display number display 59 displays the variable number of the variable display members 68a to 68c and the variable display 66 of the variable display device 60. At the time of resetting, the predetermined display number (for example, , 2000), and is decremented by "1" each time the variable operation is performed based on the detection signals from the start winning ball detectors 36a to 36c. When the display becomes "0", the next set probability set by the probability setting switch 57 is activated. That is, in the case of this embodiment, the remaining number of times (a number within 2000; a predetermined period) displayed on the variable number-of-displays indicator 59 at the time when the manager of the game hall operates the probability setting switch 57 has elapsed. Until the change, the set probability after the change is not reflected in the game. Therefore, the set probability set before operating the probability setting switch 57 is maintained until the remaining number displayed on the variable display number display 59 becomes “0”.

The current set value display 58a,
Next set value display 58b and variable display count display 59
The data displayed in (1) is backed up and stored as it is even when the power is turned off, and the data when the power is turned off is displayed when the power is turned on again. This configuration eliminates the hassle of having to reset the probability setting value every time before starting business, even for gaming machines that do not need to change the probability setting value, thereby simplifying the probability setting work. Thus, the work efficiency can be improved.

Next, the configuration of the variable display device 60 directly related to the occurrence probability of the specific game state by operating the probability setting switch 57 will be described with reference to FIGS. The configuration will be described.

The variable display device 60 is divided into a mounting board 61 mounted on the front surface of the game board 13 and a storage box 70 housing a drive mechanism mounted on the back surface of the game board 13. Therefore, first, the configuration of the mounting board 61 mounted on the surface of the game board 13 will be described.

In the upper part of the mounting board 61, a normal winning opening 63 is provided.
Is formed, and the upper decorative plate 6 is provided in front of the normal winning opening 63.
2 are installed. Further, a transparent front cover lens 64 is mounted in an arc shape below the mounting substrate 61. The front cover lens 64 has a three-dimensional design drawn on the surface of the drum-shaped variable display members 68a to 68c.
The magnifying lens portion 65 is configured to have a size such that it can be easily seen, and particularly to make the central design look larger.

A variable display 66 is provided above the front cover lens 64 and at the center of the upper decorative plate 62. The variable display 66 uses a 7-segment LED as an electrically variable display member, and is provided with “7”, “C”, “E”
The five types of symbols "H" and "J" can be displayed, and are provided for displaying a big hit mode in cooperation with the drum-shaped variable display members 68a to 68c. That is, when the combination of the display modes of the drum-shaped variable display members 68a to 68c and the display mode of the variable display 66 is a predetermined big hit mode, the variable winning prize ball device 16 is set to a first advantageous mode for the player. It changes the state. It should be noted that the variable display 66 is used to display the number of times the opening and closing plate 17 of the variable winning ball device 16 has been opened when the specific game state is set.

Also, on the upper decorative plate 62, below the variable display 66, start winning storage displays 67a to 67d.
Is provided. The start prize memory displays 67a-6
7d is the starting winning opening 2 while the variable display device 60 is operating.
This is for displaying the winning prize balls stored by winning the prizes from 0a to 20c, and up to four prize balls are stored and displayed. Therefore, at the time when the operation of the variable display device 60 is completed, if the start winning prize storage indicators 67a to 67d are lit, the variable display device 60 is operated again by the number of lit items,
The lights are turned off one by one each time the operation starts.

By the way, the combination of the above-mentioned drum-shaped variable display members 68a to 68c and the variable display 66, which is a big hit mode, is set as follows. In other words, in order to achieve the jackpot mode, the display displayed at the central portion (the magnifying lens portion 65) of the drum-shaped variable display members 68a to 68c is "Zoro eyes" (the drum-shaped variable display members 68a to 68c as described later). Is "0-9"
Is displayed on the variable display 66.
When "7" is displayed from the types, the big hit mode is set. Thus, the probability of “spots” appearing in the drum-shaped variable display members 68a to 68c is (1/10 × 1/10 × 1/10) × 10 = 10/1000 = 1/100.

On the other hand, the probability that "7" is displayed on the variable display 66 is set to five stages as shown in FIG. 6A, and the stage can be selectively set by operating the probability setting switch 57. It has become. Thus, in the setting, two out of the ten pieces of identification information are “7”, in the setting, three out of the ten pieces of identification information are “7”, and in the setting, ten pieces of the identification information are “7”. Four of the identification information are “7”, five of the ten identification information are “7” in the setting, and six of the ten identification information are “7” in the setting. It is. Accordingly, the probability of occurrence of the big hit mode in which the display of the drum-shaped variable display members 68a to 68c is "Zoro eyes" and the display of the variable display 66 is "7" is as shown in FIG.

That is, when the setting is selected by the probability setting switch 57, the occurrence probability of the big hit mode is 2 /
When the setting is selected, the probability of occurrence of the big hit mode is 3/1000. When the setting is selected, the probability of occurrence of the big hit mode is 4/1000, and the setting is selected. In this case, the probability of occurrence of the jackpot mode is 5/1000, and when the setting is selected, the probability of occurrence of the jackpot mode is 6/1000. Therefore, the manager of the game hall can arbitrarily select and set the specific game state that appears with the above-mentioned occurrence probability, thereby adjusting the payout rate without performing advanced nail adjustment for the pachinko gaming machine 1. It can be carried out.

Next, the structure of the storage box 70 attached to the back of the game board 13 will be described mainly with reference to FIGS.

While the lever 87c is excited, the stop levers 91a to 91c
The hooks 92a to 92c of the 91c rotate upward, disengage from the ratchet gears 78a to 78c, and the drum-shaped variable display members 68a to 68c rotate according to the rotation of the rotating shaft 75. When the drum solenoids 87 a to 87 c are demagnetized, the plungers 89 a to 89 c
The hooks 92a to 92c of the stop levers 91a to 91c pivot downward, and engage with the ratchet gears 78a to 78c, thereby immediately rotating the drum-shaped variable display members 68a to 68c. To stop.

In this embodiment, depending on the probability setting switch 57, the drum-shaped variable display members 68a to 68a.
Although the setting probability of 68c is not changed,
You may comprise so that this can be changed.
For example, when the two drums stop, the projector is turned on,
At this time, if there is a possibility that all three are aligned, when the remaining one drum is rotating, a predetermined light receiver is instantaneously turned off when the identification information to be aligned passes on the front side of the game board.
Therefore, the stop control of the remaining one drum may be performed at a predetermined timing after the light receiver is turned on. In this case, the content of the data for determining whether the hit stop control or the off stop control is performed can be adjusted on the game hall side. For example, in the setting, the number of hit command data; 1 in the number of outgoing command data; 14, in the setting, in the number of hit command data; 2 in the number of outgoing command data; In the setting, the number of hit command data; 4, the number of out-of-order command data; 11, and in the setting, the number of hit command data; 5, the number of out-of-order command data; However, in this case, once the data is selected,
Undo and select again.

A predetermined DC voltage is supplied from 25.

Next, the operation of the control circuit shown in FIG. 7 will be described with reference to the flow charts of FIGS. When the control circuit is turned on, the microcomputer 10
0 initializes all values and waits for the next signal. By the way, when the above-mentioned initialization is completed, the microcomputer 100 is processed so that the interrupt routine shown in FIGS. 8A and 8B is always interrupted. This interrupt routine is based on a signal interrupted every 4 ms from a pulse dividing circuit (interrupt pulse generating circuit) 129 at step S1.
To Step S4 and Steps S5 to S
7 is performed.

First, in FIG. 8A, it is determined whether or not a pachinko ball being played has won any of the start winning ports 20a to 20c based on the detection signals of the start winning ball detectors 36a to 36c. (Step S1) If any of the starting winning ports 20a to 20c has been won, the R
It is determined whether the value of the starting winning storage counter stored in the AM 103 is "4" (step S2), and "4" is determined.
If not, one is added to the numerical value stored in the start winning storage counter (step S3), and the start winning storage indicators 67a to 67d are turned on via the LED circuit 122 (step S4), and the interruption is terminated. . on the other hand,
The interruption is also ended when there is no detection signal from the start winning detectors 36a to 36c in step S1 and when the numerical value stored in the start winning storage counter is "4" in step S2.

Next, in FIG. 8B, it is determined whether or not the probability setting switch 57 of the control board box 50 has been turned on (step S5). If it has been turned on, the next setting value display 58b is displayed. The displayed digital data is changed to the next digital data (step S).
6) Then, the current set value is displayed on the current set value display 58a, the next set value newly set is displayed on the next set value display 58b, and the remaining number stored in the variable display number counter is displayed. The display is displayed on the variable number-of-displays display 59 (step S7), and the interrupt processing is terminated. Note that the variable display number counter is decremented by "1" based on the signal after the ball is won in the start winning ports 20a to 20c and the drum motor 71 of the variable display device 60 is stopped.

Returning to the main routine of FIG. 9, on the other hand, after the initialization, the game is started on the pachinko gaming machine 1 and the pachinko ball is driven into the game area 15 of the game board 13 and the driven pachinko is driven. Based on the processing of the ball by the interrupt routine, it is determined whether or not the value of the starting winning storage counter is "0" (step S).
8). When the value of the start winning prize memory counter is "0",
Do not proceed to the next process until it is no longer "0".

On the other hand, if it is determined in step S8 that the value of the start winning storage counter is not "0", the microcomputer 100 first subtracts 1 from the starting winning storage counter, and in response to this, One of the start prize memory displays 68a to 68d is turned off (step S9),
Thereafter, a solenoid excitation signal is given to the solenoid circuit 119 to turn on (excit) the drum solenoids 87a to 87c (step S10). Further, after the drum solenoids 87a to 87c are turned on, in order to completely disengage the ratchet gears 78a to 78c of the drum-shaped variable display members 68a to 68c from the hook portions 92a to 92c of the stop levers 91a to 91c. , Minute time (about 100mS)
After a lapse of time (step S11), a drum rotation control signal and a digital variable display start signal are supplied to the motor circuit 118 and the digital display drive circuit 123 to rotate and variably drive the drum motor 71 and the variable display 66. Then, the variable display of the drum-shaped variable display members 68a to 68c and the variable display 66 is started (step S).
12). Then, it is notified that the variable display is being performed (step S13).

Next, the drum-shaped variable display members 68a-68
After the variable display of c and the variable display 66 is started, it is determined whether or not the player has pressed the stop switch 9 (step S14). If the stop switch 9 has not been pressed, the next step S15 is performed. It is determined whether a predetermined time (for example, 5 seconds) has elapsed from the start of the variable display. if,
If the fixed time has not elapsed, the process returns to step S14.

In step S14, if the stop switch 9 is pressed or if a predetermined time has elapsed from the start of the variable display without the stop switch 9 being pressed, 1
After lapse of one randomly selected time TR1 from the zero time (step S16), first, the left variable display member 68a is stopped (step S17).
This is because the microcomputer 100 uses the solenoid circuit 1
19, an excitation stop signal is sent to the drum solenoid 8
This is done by deactivating 7a. At the same time, an audio signal is given to the amplifier 124, and a sound indicating that the left variable display member 68a has stopped is generated from the speaker 8 (step S18). After the left variable display member 68a stops, the drum solenoid 87b is turned off again after a lapse of one time TR2 randomly selected from the ten times (step S19).
Then, the center variable display member 68b is stopped (step S20), and a sound indicating that the center variable display member 68b is stopped is generated (step S20).
21). Further, after the central variable display member 68b stops, similarly, after a lapse of one time TR3 that is randomly selected from the ten times (step S22),
The drum solenoid 87c is turned off to stop the right variable display member 68c (step S23), and a sound indicating that the right variable display member 68c has stopped is generated (step S24). The above-mentioned selection of the minute time TR1 may be performed when the stop condition is satisfied or may be performed when the start winning is achieved. Similarly, the selection of the minute times TR2 and TR3 and the time of TR4 described later may be performed when the stop condition is satisfied, or may be performed when the previous minute time TRn-1 (n = 2 to 4) has elapsed. Good.

Three drum-shaped variable display members 68a to 68
After c stops, from the microcomputer 100,
A control signal is supplied to the light projector circuit 117, and the light
a to 83e are turned on (step S25). Floodlight 8
After the lamps 3a to 83e are turned on, one minute time TR4 selected from the six time periods elapses (step S26). After the elapse of the minute time TR4 in step S26, the digital variable display on the variable display 66 stops (step S27), and the fact that it has stopped is notified (step S28). After all the drum-shaped variable display members 68a to 68c and the variable display 66 are stopped as described above, the display of the drum-shaped variable display members 68a to 68c is "Zoro eyes" and the digital display of the variable display 66 is displayed. It is determined whether the display indicates "7" (step S29). That is, it is determined whether or not a big hit mode is set.

If it is determined in step S29 that the mode is not the big hit mode, the rotation of the drum motor 71 is stopped and the light projectors 83a to 83c are turned off.
(Step S30), "-1" processing is performed on the value of the variable display number counter (step S31), and thereafter, it is determined whether the value of the variable display number counter is "0" (step S32). , "0", the value is changed to the new next set value set by the probability setting switch 57 (step S33), and the value of the variable display number counter is newly set to "2000" (step S33). Step S34). Then, the process returns to the first step S8. In step S32, if the value of the variable display counter is not "0", the first step S32 is executed.
Return to 8.

On the other hand, if it is determined in step S29 that the hit mode is the big hit mode, the rotation of the drum motor 71 is stopped and the light
After setting a to 83c to OFF (step S35), "-1" processing is performed from the value of the variable display number counter (step S36), and thereafter, it is determined whether or not the value of the variable display number counter is "0". (Step S37), and in the case of "0", a change processing is performed to the new next set value set by the probability setting switch 57 (step S38).
Further, the value of the variable display counter is newly set to "2000".
(Step S39). Then, the process proceeds to the process shown in FIG. If the value of the variable display counter is not "0" in step S37, the process proceeds to the process shown in FIG. In this case, if the display mode of the variable display members 68a to 68c and the variable display 66 is not a big hit mode but a predetermined display mode, the small hit state is given to the player as a value different from the big hit. May be given. Of course, the occurrence probability of the small hit state may be changed.

Next, the operation of the variable winning ball device 16 in the specific game state, that is, when a big hit occurs, is shown in FIG.
This will be described with reference to FIG. When the microcomputer 100 determines the big hit state in the step S29, a sound signal is given to the amplifier 124 to generate a sound from the speaker 8 and a lamp signal is given to the lamp circuit 121 to provide the gaming effect lamps 27a, 27b, 28a, 28
b or the like is turned on or off to notify the player of the big hit state (step S40).

Next, in order to improve the player's feeling of intonation by notifying the player of the big hit state with sufficient time, a predetermined time (about 3 to 4 seconds) has elapsed (step S41). The open / close plate 17 of the variable winning ball device 11 is opened (Step S42). This is achieved by the microcomputer 100 giving a control signal to the solenoid circuit 120 and the solenoid 33 being turned on (excited). At this time, 1 is added to the number-of-openings counter that counts the number of times the opening / closing plate 17 is opened, and a timer that controls the time for exciting the solenoid 33 is set. Then, the fact that the opening / closing plate 17 is opened is notified by the speaker 8 or a lamp and the number of openings is notified to the digital display 66 via the digital display drive circuit 123 (step S43).

Next, after the opening and closing plate 17 is opened, it is determined whether or not the ball that has won the variable winning ball device 16 has won the specific winning opening 18 (step S44). This is achieved by sending the detection signal of the V winning ball detector 34 to the microcomputer 100 via the V winning ball detecting circuit 114. Microcomputer 100
However, if it is determined that there is a detection signal of the V winning ball detector 34, the value of the opening counter of the opening / closing plate 17 is "10"
Is determined (step S45).
If the value of the opening counter is not 10,
Further, it is determined whether or not the V winning ball detector 34 has already been activated (step S46). This is determined by whether or not the V winning flag is set. If the V winning flag has not been set, the V winning flag is set (step S47), and the next processing (step S4)
Proceed to 8). In step S44, the V winning ball detector 34
If it is determined that is not turned on, the step S
If it is determined in step S45 that the value of the opening counter of the opening / closing plate 17 is "10",
If it is determined that the V winning flag has already been set, the process proceeds to step S48 without setting the V winning flag.

In step S48, it is determined whether or not the 10-count detector 35 for detecting all winning balls in the variable winning ball device 16 has been turned ON. Every time the 10-count detector 35 detects a winning ball, its detection signal is sent to the microcomputer 100 via the 10-count detection circuit 115, and added to the 10-count counter provided in the RAM 103 by "1" ( Step S49). Then, it is determined whether or not the value of the above-mentioned 10 count counter is "10" (step S50). If the value of the 10 count counter is "1"
If it is determined that the time has not become "0", it is further determined whether or not the time counting of the solenoid timer has ended (step S51). The processes from S44 to S51 are repeated.

On the other hand, if it is determined in step S50 that the value of the 10 count counter is "10", or if it is determined in step S51 that the solenoid timer has expired, the microcomputer 100
Sends a stop signal to the solenoid circuit 120 to turn off (demagnetize) the solenoid 33 (step S52). Therefore, the open / close plate 17 of the variable winning ball device 16 shifts from the open state to the closed state. After closing the open / close plate 17, the microcomputer 100 allows a predetermined V reception waiting time to elapse (step S53). This is to allow time for the last ball that has won the opening / closing plate 17 to pass through the specific winning opening 18 and activate the V winning detector 34. Then, after the elapse of the waiting time, it is determined whether or not the V winning flag is set, that is, when the opening / closing plate 17 is open or after the closing and before the V reception waiting time elapses. It is determined whether or not there is a valid winning in the winning opening 18 (step S54). V
If it is determined that the winning flag is set,
The stored contents of the 10-counter and the V winning flag are cleared (step S55), and the process returns to step S42 to repeat the open state of the open / close plate 17 for a predetermined time or until a predetermined number of winning balls are generated.

On the other hand, if it is determined in step S54 that the V winning flag has not been set,
The contents stored in the count counter and the opening counter are cleared (step S56), the process returns to the first step S8, and the subsequent processes are repeated.

As is clear from the above description of the operation, in this embodiment (first embodiment), by operating the probability setting switch 57, one of a plurality of predetermined types of occurrence probabilities is selected. Since the selected value is set and displayed on the set value displays 58a and 58b, the change of the set value accompanying the probability setting work can be performed while confirming the change on the set value displays 58a and 58b one by one. This operation can be performed without error. Further, since the probability setting switch 57 described above is housed in the control board box 50 by the locking mechanism 56 so that only a specific person can operate, the setting value can be changed by a person other than the specific person. It is not possible to prevent impropriety by store staff at the game hall. In particular, in the present embodiment, even if the probability setting change is performed, the probability setting change is not immediately reflected in the game even if the probability setting switch 57 is operated.
No change is made only after the number of remaining winnings in the start winning prize openings 20a to 20c displayed on the game No. 9 has elapsed. There is an effect that the act cannot be performed.

Further, the variable display device 6 according to the above-described embodiment is used.
FIG. 11 shows a variable display device 130 different from zero. FIG.

Further, openings 155a to 155d are formed on the rear surface side of the drive unit storage box 142, and a resistor provided on the surface of the drive control board 157 which is attached in close contact with the rear surface of the drive unit storage box 142, or Electrical components such as capacitors can be projected forward from the openings 155a to 155d. However, the opening 155
“c” is for passing wirings 149a to 149c extending from the rotary drum mechanisms 143a to 143c backward. Further, a through hole (not shown) is formed in the rear surface of the drive unit storage box 142, and the phototransistors 159a to 159a provided on the drive control board 157 are formed in the through holes.
159c. Therefore, when the rotary drum mechanisms 143a to 143c are fixed to the drive unit storage box 142, the passage holes
cutout 152a formed on one side outer peripheral edge of each of a to 144c
152c are drilled to correspond to the rotating position. Then, the phototransistors 159a to 159
It is set to be ON when c is detected at the notches 152a to 152c, and is set to be OFF when it is at a position other than the notches 152a to 152c. The notches 152a to 152c are provided in the phototransistor 1
Any material may be used as long as it absorbs light emitted from 59a to 159c, and a black seal may be attached instead of cutouts 152a to 152c.

A drive control board connection connector 160 is provided below the drive control board 157 on which the phototransistors 159a to 159c are provided, and this connector 160 and drive control board connection connectors 162a and 162b of the relay terminal board 161 described below. (However, 162b is not shown) is connected by wiring, and power is supplied to the drive control board 157. The drive control board 157 has engagement holes 158a and 158b formed on the upper and lower sides of one side of the drive control board 157.
56a to 156d (156d is not shown) is supported by penetrating through some of the mounting bosses 156a and 156d, and the other side is fastened with screws to form the drive unit storage box 14.
2 is tightly fixed to the rear surface.

A relay terminal board 161 is fixed to the mounting bosses 156a to 156d. The relay terminal board 161 relays wiring from electrical components provided on the entire variable display device 130, and is provided with the above-described drive control board connection connectors 162a and 162b and the motor connection connectors 163a to 163c. Although not shown, a relay terminal board connector for connecting to an external power source is provided, and a power connector for external wiring is connected to the relay terminal board connector.

The variable display device 130 having the above configuration
The operation of is described with reference to FIGS. 12 and 13. First, it is determined whether or not a hit ball has won the start winning ports 20a to 20c and turned on the start switches 36a to 36c (step S1). Then, the data RD1 to RD3 taken out at random are determined (steps S2, S2 ', S2 ").
3 corresponds to the SP1 to SP3 motors, respectively. The data RD1 to RD3 are stored in the rotating drums 144a to 144a.
It is also data for specifying the identification information displayed in 44c. For this reason, in this operational embodiment, the combination of the identification information displayed on the rotating drums 144a to 144c is determined when a ball is hit in the start winning ports 20a to 20c. The data RD1 to RD
The selection method of No. 3 will be described later in detail.

Since the following processing is the same for each SP motor, the processing procedure for the SP1 motor will be described. After the data RD1 is determined, the SP1 motor is driven (Step S3). When driving the SP1 motor, a signal having a large pulse width is initially provided so as to gradually increase the rotation speed, and a signal having a small pulse width is gradually provided. This is performed because the starting torque of the SP1 motor is small. Also, when stopping the SP1 motor, it is preferable to stop the motor so as to gradually decrease the rotation speed. This is because if stopped suddenly, the inertia of the drum becomes larger than the magnetic attraction, and the drum may rotate extra.

After the driving of the SP1 motor is started, it is determined whether or not the sensor 1 is turned on (step S4).
If N, the step counter SC1 is reset (step S5), and the step counter SC
1 is counted (step S6). After the start of counting by the step counter SC1, it is determined whether or not there is a stop command signal by the stop switch 9 or the timer (step S7). It is determined whether the values are the same (step S8). Then, when those values become the same, the SP1 motor is stopped (step S9). At this time, the identification information displayed on the rotating drum 144a is identification information determined according to the data RD1. The processing in steps S3 to S9 is performed in step S2 for the SP2 and SP3 motors.
3'-S9 'and steps S3 "-S9", and the rotary drums 144b and 144c store the data R
The identification information corresponding to D2 and RD3 is displayed.

Incidentally, the selection of the data RD1 to RD3 is carried out, for example, by a method as shown in FIG. That is, one cycle of data (for example, 2000 times) is divided into five blocks, and one of them is further divided into four sub-blocks. Next, data for 500 times is created by randomly combining the block and any one of the sub-blocks (a) to (d). Then, data is sequentially selected from the created data for 500 times for each variable display (at the time of starting prize). If the selected data is big hit data,
The data RD1 to RD3 are determined so as to stop in the display mode other than the big hit if the data is out of the jackpot. It is preferable that the data selected once is not returned to the data of 500 times, but may be returned.

On the other hand, when all of the data for 500 times are selected (when the variable display is performed 500 times), any one of the remaining three sub-blocks excluding the sub-block combined with the block is replaced by one. The next 500 times of data are created by combining with blocks at random. Hereinafter, the block and one of the remaining two sub-blocks are combined to form the next 5
One cycle of data is created, and the next block of data is created by combining the block and the remaining sub-blocks, and when all the data has been selected, one cycle ends and the block is created. Return.

By preparing five cycles in which the number of data of the big hit in one cycle is different, and arbitrarily selecting the five cycles by operating the probability setting switch 57, the big hit mode Can be changed. For example, as shown in FIG. 13, in the setting, six jackpots are included in one cycle, in the setting, eight jackpots are included in one cycle, and in the setting, nine jackpots are included in one cycle. If the setting includes 10 jackpot modes in one cycle, and the setting includes 12 jackpot modes in one cycle, it can be selected and set by operating the probability setting switch 57. good. However, when one cycle is completed, if the next set value is the same as the current set value, the block corresponding to the same set probability again (however, the sub-block combined at that time is randomly selected, so that Is not necessarily combined with the same sub-block), the above-described one-cycle control is performed,
If they are different, one cycle of control is performed from the block corresponding to the set probability corresponding to the next set value. In addition,
As a matter of course, the set probability does not change at the time when the probability setting switch 57 is operated, and is changed when the above-described one cycle (2000 variable displays) is completed.

The data R of the variable display device 130
In order to select D1 to RD3, the method shown in FIGS. 14 to 16 may be used. First, the method shown in FIG. 14 will be described. A second variable display number counter which is reset each time a big hit display state (hereinafter, referred to as a specific display state) occurs in the control circuit is provided. If the specific display state does not occur before the value of the number counter reaches a predetermined value (until the variable display count reaches the predetermined number of times from the occurrence of the previous specific display state), the specific display state is specified at the predetermined number of variable displays. Data RD1 to RD1 are displayed.
RD3 is determined. For example, as shown in FIG. 14, if the variable display count has reached 500 times since the last occurrence of the specific display state, but the specific display state has not been reached during that time, the variable display number is not changed during the 500th variable display state. Combination data for a specific display state is given to RD1 to RD3 to force the specific game state to appear. If the predetermined value described above, that is, the maximum variable display count for achieving the specific display state is made different according to the setting content, and the setting content can be arbitrarily selected by the probability setting switch 57, the specific game state Can be changed. For example, as shown in FIG. 14, in the setting, the predetermined value is set to 500, in the setting, the predetermined value is set to 400, in the setting, the predetermined value is set to 300, and in the setting, the predetermined value is set to 250. In the setting, the predetermined value is set to 200. The variable display control until reaching the predetermined value is controlled based on a certain probability.

The method shown in FIG. 15 is different from the method shown in FIG. 14 in that the value of the second variable
RD1 to RD3 are determined so that the specific display state does not occur until the predetermined value is reached. Therefore, in this case, control is performed such that the next specific display state occurs in the variable display between the minimum variable display number and the maximum variable display number for achieving the specific display state. Thus, the minimum variable display count and the maximum variable display count for the specific display state are made different depending on the setting content,
If the setting contents can be arbitrarily selected by the probability setting switch 57, the occurrence probability of the specific game state can be changed. For example, as shown in FIG. 15, in the setting, the minimum variable display count (second predetermined value) is 10
1, the maximum variable display count (predetermined value) is set to 400, the second predetermined value is set to 76 and the predetermined value is set to 350 in the setting, and the second predetermined value is set to 51 in the setting. , The predetermined value is set to 300. In the setting, the second predetermined value is set to 26, and the predetermined value is set to 250. In the setting, the second predetermined value is set to 1 and the predetermined value is set to 200. Is done. Note that the variable display control from the second predetermined value to the predetermined value is controlled based on a certain probability.

Further, the method shown in FIG. 16 is different from the method shown in FIG. 15 in that both predetermined values (the minimum variable display count and the maximum variable display count for achieving the specific display state) as shown in FIG. ) Are predetermined five patterns (a) to (e)
Is prepared, and a pattern is created by arbitrarily collecting ten of these patterns. Then, each time a specific display state occurs from the ten patterns, one pattern is randomly selected, and control is performed based on the selected pattern.
Thus, the above five patterns (a) to (e) are
When collecting 0 pieces, if the combination of patterns is changed according to the setting and the setting content can be arbitrarily selected by the probability setting switch 57, the occurrence probability of the specific game state can be changed. For example, FIG.
As shown in (B), the pattern is created so as to include more patterns (a) and (b) that increase the probability of occurrence of the specific display state as the setting is made. Note that also in this case, the variable display control from the second predetermined value to the predetermined value is controlled based on a certain probability.

The data RD1 of the variable display device 130
13 and 16 described above in order to select .about.RD3.
The method may be performed based on a probability controlled by ordinary electronic random number generating means instead of the method described in (1).
In this case, a plurality of different probabilities depending on the settings may be prepared.

As is clear from the above description of the operation, in this embodiment (second embodiment), by operating the probability setting switch 57, one of a plurality of types of predetermined occurrence probabilities is selected. Because you can select and set, the adjustment of the payout rate does not depend on nail adjustment which requires advanced technology,
Easy to do. Further, the change is not immediately reflected in the game even if the probability setting switch 57 is operated, and is not changed unless the remaining number of times of one cycle (variable display number) at the time of setting has elapsed. This also has the effect that operations that cause the player to feel distrust and clerks at the game arcade cannot perform wrongdoing.

Although the method shown in FIGS. 14 to 16 is applied to the variable display device 130 according to the second embodiment, this method is applied to the variable display device 60 according to the first embodiment. Is also good. In this case, until the variable display count reaches the minimum variable display count or after the maximum variable display count has been reached, the above-described control of turning on the projector at the time when two drums are stopped (there is a possibility that three are set). If so, when the remaining one drum is rotating, a predetermined light receiver is instantly turned on when the matching identification information passes through the front of the game board. The control is switched to a control for stopping the remaining one drum at a predetermined timing after being turned on. After the variable display count reaches the minimum variable display count, stop control of the remaining one drum is performed so as to be off until the variable display count reaches the minimum variable display count.

In the above-described embodiment, the variable display devices 60 and 130 and the variable prize ball device 16 are provided separately. However, the variable display devices 60 and 130 and the variable prize ball device 16 may be provided integrally. Device 16 and variable display devices 60 and 130
Is not limited to the illustrated one. For example, as a variable winning ball device, a pair of opening / closing wings or a sliding piece may be used instead of the opening / closing plate 17, and as a variable display device, LCD, EL, roulette may be used instead of a drum-shaped variable display member. It may be of a type using a type, a leaf type, a belt type, a dot display, another display, or the like. Further, the stop switch 9 for stopping the variable display of the variable display devices 60 and 130 may be omitted, and only the automatic stop may be performed by a timer. Further, the stop order is not limited to the embodiment. Furthermore, the variable display member (including the rotating drum) and the variable display of the variable display may be configured to be started when the power is turned on, and to be variably started again by a winning start. In this case, it is preferable to change the brightness of the variable display of the variable display member or the variable display, or to change the speed of the variable display, in order to clarify that the variable start has been made by the start winning. In addition, the variable display of the variable display member and the variable display is normally displayed in a variable manner,
You may comprise so that it may stop by a start winning.

Although the variable display number is set in the above two embodiments as a condition for changing the occurrence probability of the specific game state, various factors related to the game can be selected. For example, when a certain time (for example, 24 hours) has elapsed, when the number of specific game states reaches a predetermined number, when the number of out-balls reaches a predetermined number, and the like.

Further, as the specific game state, a state in which the variable winning ball device can be opened under predetermined conditions has been exemplified.
If the continuation condition is configured to be adjusted by, for example, a variable display, the V continuation may be defined as a specific game state, and the continuation rate may be adjusted. Furthermore, the range or stage in which the occurrence probability can be adjusted is not limited to the above-described embodiment, and the adjustment method is not to change the switch by pressing, but may be set by an operation that complicates the procedure. Alternatively, the setting means may be provided in a central control room of a game arcade, instead of a ball-and-play game machine, so that it can be remotely operated. Furthermore, if the content of the game is configured such that the probability of occurrence of the specific game state can be adjusted on the gaming side,
Anything is fine. In addition, as a game value given by the occurrence of the specific game state, a predetermined number of prize balls are paid out by the occurrence of the specific game state, or a predetermined score in the card type ball game machine described below. May be given.

Furthermore, in the above-described embodiment, the ball game machine is of a type in which a player borrows a ball borrowed by the player and puts the ball into the ball supply tray 7 to play a game. A so-called card-type ball-and-ball game machine may be used in which a game can be played by ejecting an enclosed ball sealed in the game machine with a medium.
