The special symbol display device 7 is a symbol display CPU.
(Not shown) and a memory or the like (not shown), are connected so as to be able to communicate in one direction from the CPU 25 via the interface 35, and have special symbols on the display screen according to display command data from the CPU 25. And pictures.

The game contents of the pachinko gaming machine of the embodiment will be schematically described. When the game ball passes through one of the left and right gates 3 and 4, the symbol on the symbol display 9 usually starts changing, and stops changing after about 5.0 seconds.
Note that there are ten types of symbols commonly used for symbols, from “0” to “9”. When the normal symbol whose fluctuation is stopped is “1,” “3,” “5,” “7,” or “9,” the normal electric accessory 5 is activated, and the starting winning opening 8 is the symbol of the special symbol display device 7. When the jackpot lottery probability related to the fluctuation is the normal probability, the opening is expanded for about 0.3 seconds, and when the jackpot lottery probability is the high probability, it is opened for about 4.5 seconds. When three pachinko balls are awarded to the opening winning opening 8 during opening, the opening operation of the opening opening opening 8 ends even within the opening time.

When the pachinko ball wins the starting winning opening 8,
The special symbol of the special symbol display device 7 starts to change in the order of the left symbol, the right symbol, and the middle symbol. When about 7.7 seconds or more elapse after the start of the symbol change, the symbols are stopped in the order of the left symbol, the right symbol, and the middle symbol, and the special symbol is determined. However, when the lottery probability of the big hit related to the symbol change of the special symbol display device 7 is a high probability, the change time is shortened, and when about 5.2 seconds or more elapse after the symbol change starts, the left symbol, the right symbol The symbols are stopped in the order of the symbol and the middle symbol, and the symbol is determined.

There are a total of 30 types of symbols used for the left symbol and the right symbol: ten types of symbols (large), ten types of symbols (medium), and ten types of symbols (small). The contents are as shown in FIG. In addition, as for the kind of design which is used for the medium design, 12 kinds of design (large),
12 types of symbols (medium) and 12 types of symbols (small), total 3
There are six types. The contents are as shown in FIG.

When the combination of the left, middle, and right symbols determined to be stopped is the big hit combination shown in FIG. 23, that is, "111", "222", "333",
"444,""555,""666,""7777,"
In the case of “gold, silver and gold”, “gold, gold and gold”, “cherry blossoms”, “ball A ball B ball A”, and “ball A ball A ball A”, a jackpot is established, that is, the condition device is The special winning opening solenoid SOL2 is operated, the opening and closing door 16 is rotated forward, and the special winning opening 17 is opened for a predetermined time (29.0 seconds). In addition, in cases other than the above-mentioned combination, it will come off,
Condition device does not work. Further, as in the conventional case, up to four winning memories in the starting winning opening 8 are stored.

If ten game balls are won during opening of the special winning opening 17, the special winning opening 17 is closed with the tenth winning. If the game ball passes through the specific area 18 during the opening of the special winning opening 17 and within about 1.5 seconds from the time when the special winning opening 17 is closed, the accessory continuous operation device (establishment of continuous operation) is activated. Then, after the opening of the special winning opening 17 being opened, the special winning opening 17 is repeatedly opened again. The opening operation of the special winning opening 17 is a maximum of 16 times including the first opening operation.

When the special symbol display device 7 has established a big hit and the condition device is activated, the special symbol display device 7 starts the next symbol change from the time of operation of the condition device to the special symbol display device. A lottery is performed to determine whether or not to switch the appearance probability of the big hit symbol on the symbol display device 7.

If the lottery result of whether or not to switch the appearance probability of the big hit symbol is a win, the special symbol display device 7 is operated from the stop of the operation of the condition device to the start of the operation of the next condition device.
Is switched, and for example, the jackpot lottery probability shifts to the high probability (6/359). If the lottery result is out of order, the lottery probability of the big hit related to the symbol change of the special symbol display device 7 from the stop of the operation of the condition device to the start of the operation of the next condition device is, for example, a low probability (1/359). ).

Next, a probability switching setting means for setting the switching of the appearance probability of the big hit symbol relating to the special symbol display device 7 according to the present invention by using a random value for probability variation determination, and a probability variation set by the probability switching setting means. The display control means for controlling the display of the probability switching determination symbol provided separately from the big hit symbol and the out-of-hit symbol corresponding to each of the judgment random numbers will be described.

Although not shown as a flowchart,
The CPU 25 shown in FIG. 2 performs initialization processing when power is turned on, and performs various registers, various flags,
Initialize various counters and various storage areas. In the initialization process, the initial value of the jackpot numerical value NUBA used for setting the jackpot related to the special symbol display device 7 is set to 0. Also, the initial value of the probability variation numerical value PNB to be used for the lottery of whether or not to perform the probability variation is set to 0.

When the lottery probability regarding the big hit is low (1/359), it is compared whether the random number selected for the big hit matches the big hit determination value "7" (the big hit is determined). It is determined whether or not there is). In addition, when the lottery probability regarding the big hit is a high probability (6/359), the big hit numerical value randomly selected is a big hit determination value “7”, “71”, “107”, “173”, “22”.
7 "and" 307 "are compared (whether or not a big hit is determined).

FIG. 4 is a flowchart schematically showing a portion of the special symbol display device 7 in the game control program stored in the ROM 26 for updating the big hit value and the probability change value related to the symbol variation.

The clock reset circuit 28 shown in FIG.
A reset signal is sent to the CPU 25 every 2.000 ms. When a reset signal is input to the CPU 25, the CP
U25 interrupts the main routine of the game control process including the symbol variation process related to the special symbol display device 7, for example,
The process proceeds to the numerical value update process shown in the flowchart of FIG.

When starting the numerical value updating process, the CPU 25 increases the value of the big hit numerical value NUBA by one (step A01), and determines whether or not the updated big hit numerical value NUBA has reached 359 (step A01). Step A0
2). The initial value of the big hit value immediately after turning on the power is
It is set to 0 by the initialization processing.

When the value of the big hit numerical value NUBA has reached 359, the CPU 25 sets the big hit numerical value NUBA to 0 and proceeds to step A04 (step A0).
3) If the value of the big hit number NUBA has not reached 359, the process directly proceeds to step A04.

As described above, the value of the jackpot numerical value NUBA starts from the initial value 0 when the power is turned on, and is set to 0 to 0 every predetermined period (every time a reset signal is input at a period of 2.000 ms). 1 within a preset range of 358
It is updated cyclically one by one.

The CPU 25 that has proceeded to step A04
The value of the probability variation numerical value PNB is increased by one (step A).
04), the updated probability variation numerical value PNB is 2
Is determined (step A05). The initial value of the probability variation numerical value PNB immediately after the power is turned on is:
It is set to 0 by the initialization processing.

When the value of the probability variation value PNB has reached 2, the CPU 25 sets the probability variation value PNB to 0 and returns to the main routine (step A0).
6) If the value of the probability variation numerical value PNB has not reached 2, the flow directly returns to the main routine.

As described above, the value of the probability variation numerical value PNB starts from the initial value 0 at power-on, and is set to 0 every predetermined period (every time a reset signal is input at a period of 2.000 ms). Are updated cyclically one by one within the range of 1 to 1.

The range of values that can be taken by the probability variation numerical value PNB is only 0 and 1 in the above example, but is not limited to this, and the value to be compared with the probability variation numerical value PNB in step A05 is arbitrary. By changing it, it can be arbitrarily changed, for example, from 0 to 10.

FIG. 5 is a flow chart showing a process related to winning detection of the starting opening winning detection switch SW1, which is a part of the switching process executed by the CPU 25.

The CPU 25 has a start opening winning detection switch S
Each time the winning detection signal from W1 is inputted, the big hit numerical value N is stored in the unused big hit numerical storage register RAN (i).
The current value of UBA is stored (step B01 to step B05). The CPU 25 searches the storage state identification flag F (i) based on the value of the index register i (step B02 to step B03) each time a winning in the start winning opening 8 is detected (step B01). Flag F
If (i) is not stored (value is 0), the current value of the big hit numerical value NUBA is stored in the big hit numerical storage register RAN (i) (step B04), and the storage state identification flag F
(I) is set to be stored (value is 1) (step B0)
5).

If the storage state identification flag F (i) is not stored (the value is not 0), the value of the index register i is updated by one, and the next storage state identification flag F (i) is searched (step). B06, step B07), it is determined whether or not the storage state identification flag F (i) indicates that there is no storage (step B03). Note that the big hit value storage register RAN
If all of 1 to RAN4 have already stored the jackpot numerical value NUBA, even if the value of the index register i is updated to 4, the storage state identification flags F (i) are all stored, so the storage state identification flag F After it is determined that (4) has been stored, the index register i is updated and the value of the index register i reaches 5, the result of the determination in step B07 becomes true, and the current value of the jackpot numerical value NUBA is obtained. Is not stored. As a result, the value of the jackpot numerical value NUBA is up to 4
Up to the maximum.

Here, since the timing of winning the pachinko ball into the starting winning opening 8 is random, the value of the numerical value NUBA for the jackpot which is randomly selected based on the detection of the winning of the pachinko ball into the starting winning opening 8 is determined. Randomness is also guaranteed.

Accordingly, the jackpot numerical value storage register RAN1 storing the jackpot numerical value NUBA randomly selected.
To RAN4 can also be used as the jackpot determination random numbers.

FIGS. 6 and 7 are flowcharts showing the outline of the symbol changing process of the special symbol display device 7 executed by the CPU 25, and show a process related to the big hit determination which is a part of the process. When starting the symbol variation process, the CPU 25 first determines whether or not a new symbol variation can be started (step C01). In addition, when the symbol has already been changed (during the change of the symbol or during the display of the stopped symbol that has been fixed) and during the big hit operation (during the operation of the condition device), it is impossible to start a new symbol change.

When it is possible to start a new symbol change, the CPU 25 sets the above described big hit numerical value storage register RA.
The big hit numerical value NUBA stored in N1 is stored in the big hit numerical storage register RAN0 this time (step C
02), big hit value storage registers RAN2 to RAN
4 is sequentially shifted to the big hit value storage registers RAN1 to RAN3 (step C03), the contents of the big hit value storage register RAN4 are cleared, and the big hit value storage register RAN is cleared.
Then, the storage state determination flag F (4) corresponding to No. 4 is cleared to 0, and the big hit value can be stored in the big hit value storage register RAN4 (step C04).

Next, it is determined whether the result of the symbol change performed this time is a big hit or a miss (step C05).
The CPU 25 determines the set state of the probability variation flag,
High probability that the probability variation flag is set (6/35
In the case of 9), this time the big hit numerical value storage register RAN
The jackpot numerical value NUBA stored in 0 is the jackpot determination value at the time of high probability, “7”, “71”, “107”, “17”.
3 "," 227 ", or" 307 "is determined, and if the jackpot numerical value NUBA matches any of the six jackpot determination values, it is determined to be a jackpot. On the other hand, if the big hit numerical value NUBA does not match any of the above six big hit determination values, it is determined that there is a miss (step C07).

In the case of a low probability (1/359) in which the probability variation flag is cleared, the big hit numerical value NUBA stored in the current big hit numerical storage register RAN0 is compared with the big hit determination value "7". , Big hit NUBA
Is determined to be a big hit if the numerical value NUBA does not match the big hit determination value "7" (step C06).

When a big hit is determined, the big hit flag is set (step C08), and when it is determined that the big hit is cleared, the big hit flag is cleared (step C09).

Next, the CPU 25 sequentially sets various conditions necessary for symbol fluctuation (steps C10 to C10).
Step C11). In addition, about the setting of various conditions required for a symbol change, detailed description will be omitted and will be briefly described.

First, a left symbol, a right symbol and a middle symbol to be finally fixed and stopped are determined (step C10). If it is determined to be a big hit, it is determined to be one of the combinations of the big hit symbols shown in FIG. 23, and if it is determined to be a big hit, it is determined to be one of the combinations of the missing symbols other than the big hit symbols.

When it is determined that the big hit is determined, the type of the reach operation is determined so that the big hit symbol determined in the above processing is finally stopped and displayed. Decide whether or not to reach during a change, and if you want to do reach (in this case,
Although the reach operation is performed but eventually comes off, it is referred to as "miss reach"), and the type of the reach operation is determined so that the off design determined in the above process is finally stopped and displayed. Depending on whether the reach operation is performed or not, one of the plurality of symbol variation patterns is determined.

Further, it is determined whether or not a big hit notice is given during the symbol change. Further, it is determined whether or not the re-change operation of the left symbol, the right symbol and the middle symbol is performed during the symbol variation (step C11).

After these various conditions are set, the change of the left symbol, the right symbol and the middle symbol is started (step C1).
2) After passing through the determined fluctuation pattern, the left symbol, the right symbol and the middle symbol are stopped and displayed and fixed (step C1).
3). If it is determined in step C06 or step C07 that a big hit has occurred, one of the big hit symbols shown in FIG. 23 is stopped and displayed. If it is determined in step C06 or step C07 that the big hit has been lost, a non-big hit symbol is removed. The symbol is stopped and displayed.

When the left symbol, the right symbol and the middle symbol are stopped and displayed, the CPU 25 determines the big hit flag (step C14), and activates the condition device only when the big hit flag is set (step C15). . Further, when the condition device is operated, the opening number counter C1 for counting the number of opening of the special winning opening 17 is cleared to 0 (step C).
16) The operation start display time is set in the timer (step C17), and the routine shifts to the interval processing in FIG. In the case of a departure, the current drawing variation process ends.

FIG. 24 is an operation timing chart showing the condition device, the opening and closing operation of the special winning opening 17, and the operation timing of the accessory continuous operation device. FIG. 25 is a timing chart showing the processing timing by the CPU 25 relating to the opening and closing operation of the special winning opening 17. Further, FIG.
9 is a timing chart showing the processing timing by the CPU 25 relating to the accessory continuous operation device for performing the continuous opening operation of the special winning opening 17.

In the following description, the special symbol display device 7 starts the next symbol by the requirement according to claim 4, that is, when the lottery of the random number for probability variation is determined to display the big hit symbol. An embodiment according to the requirements described in claim 5, which is one of the modes performed before the start of the change, will be described as a representative. That is, the first opening of the special winning opening 17 that operates based on the display of the big hit symbol from the point in time when the lottery of the random number for probability change (numerical value for probability fluctuation PNB) is determined to display the big hit symbol. An embodiment performed before the start of the operation will be described.

When the condition device is actuated by the stoppage of the big hit symbol determination, as shown in FIGS.
Until the operation start time (7.824 seconds) set at 17 elapses, the closed state of the special winning opening 17 is maintained. The interval processing relates to processing for maintaining the closed state of the special winning opening 17 from the time when the condition device is activated to the time when the condition device is activated. This is a process executed only.

When the interval processing is started, the CPU 25 reads the probability variation numerical value PNB (step S1).
00). Since there is no causal relationship between the operation timing of the condition device and the update timing of the probability fluctuation value PNB, the value of the probability fluctuation value PNB read from the random operation of the condition device is treated as a random number. be able to.

Next, it is determined whether or not the operation display time has ended (step S101). At the time when the interval processing is started, the operation display time has not ended, so the flow shifts to step S102, performs a subtraction processing of the timer in which the operation display time is set, and shifts to the probability switching determination symbol display processing of step S103. .

FIG. 12 is a flowchart showing a subroutine of the probability switching determination symbol display processing. CPU25
First, a lottery is performed to determine whether or not to perform a probability change. That is, it is determined whether or not the probability variation numerical value PNB read in the process of step S100 matches the value “1” at which the probability variation is performed (step S200).
Since the range of possible values of the probability variation numerical value PNB is only 0 and 1, the lottery probability of whether or not to perform the probability variation is １ ／.

If the probability variation numerical value PNB matches the value "1" at which the probability variation is performed, the CPU 25 determines the probability switching (switching of the appearance probability of the big hit symbol) to perform the probability variation. Display a business symbol (step S201),
While setting the probability variation flag (step S20)
2) If the probability variation numerical value PNB does not coincide with the value "1" at which the probability variation is performed, a probability switching determination symbol indicating that the probability variation is not performed is displayed (step S20).
3), clear the probability variation flag (step S20)
4).

After the processing in step S202 or the processing in step S204, the CPU 25 executes step S1 in FIG.
Return to 01. Hereinafter, the CPU 25 performs steps S101 to S10 until the operation display time ends.
3 is repeated, and the probability switching discrimination symbols corresponding to the presence or absence of the switching of the appearance probability of the big hit symbol are displayed.

FIG. 27 is a diagram showing one display mode of the probability switching determination symbol indicating that the probability change is performed, and FIG. 28 is a diagram illustrating one display mode of the probability switching determination symbol indicating that the probability change is not performed. FIG. 27 and 28 both show a case where the left symbol, the right symbol, and the middle symbol are fixedly stopped at the big hit symbol of "7, 7, 7".

As shown in FIG. 27, when the lottery result as to whether or not to change the probability is a winning and the probability is changed,
The character "sakura face" shown in the figure appears at the center of the picture display section 15 shown in FIG. 3, moves to the left while blinking, and stops slightly to the left in the center.

Then, the character "Sakuragai" looks happy and repeats blinking while moving the mouth in accordance with the balloon "Feel very good", and the character "Sakuragai" looks happy. With the expression, the mouth is kept open and a balloon “Probability variation” is displayed to notify the player that the probability variation is to be performed.

As shown in FIG. 28, when the lottery result as to whether or not to change the probability is out of order and the probability is not changed, the character shown in FIG. 15 is placed at the center of the picture display section 15 shown in FIG. The "cherry blossom face" appears, moves to the left while blinking, and stops slightly to the left in the center. The display mode up to this point is the same as the case of performing the probability fluctuation, but differs from the next display mode.

When the probability change is not performed, the character "Sakura face" changes to a sad expression, and the player is notified by a facial expression that the probability change is not performed.

As described above, due to the difference in story development due to the movement of the specific character “Sakuragaoka” displayed on the display screen, the appearance probability of the big hit symbol according to the lottery result as to whether or not to change the probability is determined. Displays the presence or absence of switching.

In particular, when the appearance probability of the big hit symbol in the special symbol display device 7 is switched, a symbol for probability switching discrimination different from the big hit symbol and the off symbol is displayed to transfer the change of the probability variation to the player. Since the notification is made, the interest of the player can be satisfied.

If the lottery result indicating whether or not to perform the probability change is a winning at the time of performing the probability switching discrimination symbol display process, the process of step S202 is performed to perform the probability change. As a result of the flag being set, when a new symbol change is started in the symbol change process, the big hit numerical value NU stored in the present big hit numerical storage register RAN0.
BA is the jackpot determination value at the time of high probability “7”, “7”
1 "," 107 "," 173 "," 227 "," 30 "
7 "(see steps C05 to C07 in FIG. 6).

When the operation display time ends (step S101), the CPU 25 ends the interval processing,
Shift to jackpot processing.

FIGS. 9 to 11 are flowcharts of the big hit process executed by the CPU 25. The big hit process is a process that is executed only when it is determined in the symbol variation process that the big hit has occurred and the condition device is in the operating state.

When the big hit process is started, the CPU 25
First, it is determined whether or not the condition device is operating (step S01). If the condition device is not operating, the result of the determination in step S01 becomes false, so that no substantial jackpot processing is performed.

When the condition device is operating, the big hit processing is executed. After the determination in step S01, the CPU 25
Stops the operation of the continuous actor (step S0).
2) The opening time (29.00 seconds) of the special winning opening 17 is set in a timer (step S03). Then, a winning number counter C2 for counting the number of pachinko balls won in the special winning opening 17 is set to 0 (step S04), and the value of the opening number counter C1 is increased by one (step S0).
5) Open the special winning opening 17 by outputting a drive excitation signal to the special winning opening solenoid SOL2 (step S0).
6) The specific area 18 is opened by rotating the specific area door by outputting a drive excitation signal to the specific area door opening solenoid SOL3 (step S07), and step S08 is performed.
Move to Thus, the first opening operation of the special winning opening 17 is started. Also, one pachinko ball can pass through the specific area 18 and win.

The CPU 25 that has proceeded to step S08,
It is determined whether or not a pachinko ball has won the special winning opening 17. That is, it is determined whether or not there is a winning detection signal from the special winning opening winning detection switch SW3 (step S0).
8).

When the winning detection signal is inputted from the special winning opening winning detection switch SW3, the CPU 25 increases the value of the winning number counter C2 by one (step S09).
Move to step S10. On the other hand, if there is no input of the winning detection signal from the special winning opening winning detection switch SW3 in step S08, the CPU 25 directly proceeds to step S10.

In step S10, it is determined whether or not the pachinko ball has won a specific area 18 provided inside the special winning opening 17 (step S10). That is, CP
U25 determines whether or not there is a winning detection signal from the specific area passage detection switch SW4, and when the winning detection signal is input from the specific area passage detection switch SW4,
The accessory continuous operation device is operated (step S11), and the process shifts to the timer process of step S12. If no winning detection signal is input from the specific area passage detection switch SW4, the process directly shifts to the timer process of step S12. In the timer processing of step S12, a timer value that sets the opening time of the special winning opening 17 is subtracted.

After the processing in step S12, the CPU 25
The special winning opening 17 is determined in steps S13 and S14.
It is determined whether or not the closing condition is satisfied. That is, in step S13, it is determined whether or not the number of the pachinko balls that have won the open special winning opening 17 has reached 10 (step S13). If the current value of the winning number counter C2 for counting the number of pachinko balls that have won the special winning opening 17 has reached 10, the CPU 25 proceeds to step S1.
Then, the pause time from the closing of the special winning opening 17 is set in a timer (step S15), and the output of the drive excitation signal of the special winning opening solenoid SOL2 is turned off to close the special winning opening 17 (step S15). Step S16). Thus, even during the opening time of the special winning opening 17, the special winning opening 1
When the number of pachinko balls that have won the number 7 has reached 10, the special winning opening 17 is closed.

In step S13, if the number of the pachinko balls that have won the open special winning opening 17 has not reached ten, the CPU 25 proceeds to step S14. In step S14, it is determined whether or not the opening time of the special winning opening 17 has ended (step S14). CPU2
When the opening time of the special winning opening 17 is completed, the process proceeds to step S15, and the pause time from the time when the special winning opening 17 is closed is set in a timer (step S15), and the drive of the special winning opening solenoid SOL2 is excited. By turning off the signal output, the special winning opening 17 is closed (step S16).

If the number of the pachinko balls which have won the special winning opening 17 has not reached 10, and the opening of the special winning opening 17 is in progress, steps S13 and S13 are executed.
14 are false, the CPU 25 determines in step S0
8, the processing loop formed by steps S08 to S14 is repeated until one of the determination results in steps S13 and S14 becomes true.

Now, at step S16, the special winning opening 17
Is performed, the CPU 25 determines whether or not the condition for terminating the big hit process is satisfied by the processes in and after step S17.

In step S17, the special winning opening 17
It is determined whether or not the number of times of opening has reached 16. CPU
25, when the number of times the special winning opening 17 has been opened reaches 16, the operation of the accessory continuous operation device is ended (step S2).
4) The operation of the condition device is terminated (step S25), and the big hit process is terminated. As a result of the termination of the operation of the condition device, the big hit processing is not performed after the next cycle.

If the CPU 25 determines in the determination processing of step S17 that the number of times of opening the special winning opening 17 has not reached 16, the processing proceeds to step S18 and thereafter. In other words, the closed state of the special winning opening 17 is maintained until the special winning opening pause time (about 1.5 seconds after the closing of the special winning opening 17) elapses, and the accessory continuous operating device is in operation. If not, about 1.5 from the closing of the special winning opening 17
For a second, the process proceeds to a process of validating the winning detection of the pachinko ball in the specific area 18.

In step S18, it is determined whether or not the accessory continuous operation device is operating (step S1).
8). If the pachinko ball has won in the specific area 18 provided inside the special winning opening 17 during opening of the special winning opening 17 at this time, as a result of the processing of step S10 and step S11, the The continuous actuator is operating. If the continuous actuating device is in operation (note that
The condition device remains operating), and the CPU 25 proceeds to step S21.

If it is determined in step S18 that the accessory continuous operation device is not in operation, the process proceeds to a process for validating the detection of winning of a pachinko ball in the specific area 18.
After determining that step S18 is false, the CPU 25 determines whether there is a winning detection signal from the specific area passage detection switch SW4 (step S19).

In step S19, when a winning detection signal is input from the specific area passage detection switch SW4, the CPU 25 operates the accessory continuous operation device (step S20), and proceeds to step S21. On the other hand, in step S19, the specific area passage detection switch SW4
If no winning detection signal is input from the CPU 25, the CPU 25
Directly proceeds to step S21.

When the CPU 25 proceeds to the timer process of step S21, the CPU 25 subtracts the timer value set with the special winning opening pause time (step S21), and determines whether or not the special winning opening pause time has ended (step S21). S22).

Thereafter, the CPU 25 proceeds to steps S18 to S22 until the special winning opening pause time ends.
Is repeated, and if the continuous actuation device is not yet in operation, it is determined whether or not there is a winning detection signal from the specific area passage detection switch SW4. Operate.

When the special winning opening pause time ends, the CPU 2
In step S5, after the step S22 is determined to be true, it is determined whether or not the accessory continuous operating device is operating (step S23). In step S23, if the accessory continuous operation device is in operation, the CPU 25 determines that step S23 is true, and the condition device remains in operation. As a result, the big hit process is started from the start, and is closed. Big Winner 17
Is opened again (moving to the next round).

As described above, the number of times of opening the special winning opening 17 is one.
If it does not reach 6, during the opening of the special winning opening 17 this time,
Alternatively, if the winning of the specific area passage detection switch SW4 is detected within the special winning opening pause time from the closing of the special winning opening 17 this time, the continuous actuation device for actuation is activated, and the special winning opening pause time is set. After the elapse, the second opening operation of the special winning opening 17 is started.

As a result of the restart of the jackpot process, the process of step S02 is performed, and when the special winning opening 17 is opened, the operation of the accessory continuous operating device is stopped.

Although not shown in the flowchart, the operation of the solenoid SOL3 for opening the specific area door is terminated when 50 ms has elapsed from the time when the specific area passage detection switch SW4 detects the winning (see FIG. 26).

However, if there is no winning in the specific area 18 while the special winning opening 17 is open and there is no input of the winning detection signal from the specific area passing detection switch SW4 during the special winning opening pause time, the CPU 25 After determining that the step S23 is false, the process shifts to the step S25 to terminate the operation of the condition device and terminate the big hit processing. As a result of the termination of the operation of the condition device, the big hit processing is not performed after the next cycle.

As described above, the number of times of opening the special winning opening 17 is one.
Even if it has not reached 6, this grand prize opening 17
During the opening of the pachinko stadium, no pachinko ball wins in the specific area 18 provided inside the special winning opening 17 and
When the winning of the specific area passage detection switch SW4 is not detected within the special winning opening pause time from the closing of
In the case where the operation of the accessory continuous operating device is stopped, the closed special winning opening 17 does not open again, and the big hit operation ends (see FIG. 26).

Although not shown in the flowchart, the solenoid SOL3 for opening the specific area door SOL3 does not detect the winning detection signal from the specific area passage detection switch SW4. Ends the operation (see FIG. 26).

As described above, the lottery of the random number value for probability variation (numerical value PNB for probability variation) is based on the final display of the big hit symbol from the time when it is determined that the big hit symbol is to be displayed (that is, from when the condition device is activated). Has been described until the start of the first opening operation of the special winning opening 17 that operates in the above-described manner.
The present invention is not limited to the lottery timing of the above embodiment, but may be changed to various lottery timings within the scope of the gist of the present invention.

FIG. 29 is a timing chart showing an embodiment of the lottery timing of the random number for probability change set in connection with the operation of the condition device and the opening and closing operation of the special winning opening.
The section a in FIG. 29 corresponds to the above-described embodiment, and the lottery of the random number for probability change is performed based on the display of the big hit symbol from the time of the operation of the condition device. This is performed until the start of the second opening operation.

In the section b, the first opening operation of the special winning opening 17 operated based on the display of the big hit symbol is started from the time when the lottery of the random number for probability variation is determined to display the big hit symbol. This indicates that the processing is performed before the end, and corresponds to the requirement described in claim 6.

In this case, in the flowchart of the interval processing in FIG. 8, the processing of reading the probability variation numerical value PNB and the processing of displaying the probability switching determination symbol are not performed (the steps S100 and S103 are not performed). In the big hit processing, after opening the special winning opening in step S06, it is determined whether or not the value of the opening number counter C1 is 1, and when the value of the opening number counter C1 is 1, the value of the probability variation numerical value PNB is determined. The configuration may be such that the reading process and the probability switching determination symbol display process are performed.

In a section c in FIG. 29, it is shown that the lottery of the random number for probability variation is performed after the end of the continuous opening operation of the special winning opening which operates based on the display of the big hit symbol. It corresponds to the requirements described in.

In this case, in the interval processing flowchart of FIG. 8, the processing of reading the probability variation numerical value PNB and the processing of displaying the probability switching determination symbol are not performed (without performing steps S100 and S103). Subsequent to the end of the operation of the condition device in step S25 in the big hit process, the reading process of the probability variation numerical value PNB and the probability switching determination symbol display process may be performed. In addition, the process regarding the lottery of the random number for probability variation may be performed as a separate process performed at the end of the big hit process, or may be performed in the big hit process.

The section d in FIG. 29 indicates that the random number value for probability variation is selected after the start of the first opening operation of the special winning opening that operates based on the display of the jackpot symbol. This corresponds to the requirement described in claim 8.

In this case, in the interval processing flowchart of FIG. 8, without performing the process of reading the probability variation numerical value PNB and the process of displaying the probability switching determination symbol (without performing steps S100 and S103), The configuration may be such that the reading process of the probability variation numerical value PNB and the probability switching determination symbol display process are performed during the big hit processing.

In the section e in FIG. 29, the lottery of the random number for probability variation is performed during the continuous opening operation of the special winning opening 17 operated based on the display of the big hit symbol. This is performed after determining that there is no winning in the area 18, and corresponds to the requirement described in claim 9. In the figure, the fall of the condition device indicated by the dashed line is due to the fact that the winning in the specific area 18 is not finally detected before the opening number of the special winning opening 17 reaches 16 times. This indicates that the continuous operation device for the accessory has been stopped and the condition device has been completed.

In this case, in the interval processing flowchart of FIG. 8, the winning process is not performed for the probability variation numerical value PNB and the probability switching discriminating symbol display process (the steps S100 and S103 are not performed), and the big prize is won. When the result of the determination in step S23 as to whether or not the continuous actuation device for the accessory is in operation at the time when the mouth pause time has elapsed is negative, the reading process of the probability variation numerical value PNB and the probability switching determination symbol display are continued. The processing may be performed.

Further, the probability switching discrimination symbol indicating that the probability variation is performed and the probability switching discrimination symbol indicating that the probability variation is not performed are not limited to the display modes in the above embodiment. However, various display modes can be changed within the scope of the present invention.

FIG. 30 is a diagram showing a second display mode of the probability switching determination symbol. For example, a configuration may be used in which the presence or absence of switching of the appearance probability of the big hit symbol is displayed using the background displayed on the picture display section 15. In the figure, the background "Kokugikan" is used as the probability switching determination symbol,
The display state in which the background “Kokugikan” scrolls up and down (shaking motion) indicates that the probability changes. Although not shown, the background “Kokugikan” maintains the still display, indicating that the probability does not change.

Next, the display operation of the ordinary symbol display 9 in the present embodiment will be described. FIG. 37 is a timing chart showing the processing timing of the CPU 25 with respect to the ordinary symbol display 9. When the pachinko ball passes one of the left and right gates 3 and 4, the gate switch SW
2, SW2 'detects the passage of the pachinko ball through the gate.

The clock reset circuit 28 is connected to the CPU 25.
When the reset signal is input to the CPU 25, the CPU 25 performs an interrupt process. After the input processing for various switches, when the input of the starting opening winning detection switch SW1 is detected in the switch determination processing, and when the detection signal from one of the gate switches SW2 and SW2 'is input in the interrupt processing, Normally, a hit determination numerical value for a symbol (which is cyclically updated in a predetermined cycle within a range of 0 to 9) is stored in the RAM 27. Note that the hit determination value for the normal symbol is determined by the gate switches SW2 and SW.
4 corresponding to the number of detection signals from any of 2 ′
Store up to one. Then, it is determined whether or not the normal symbol hit determination value stored in the RAM 27 matches a predetermined hit determination value. It should be noted that a hit occurs when the hit value for the normal symbol stored in the RAM 27 matches the hit determination value, and the hit occurs when the hit value for the normal symbol stored in the RAM 27 does not match the hit determination value. . The probability of winning is set to 1/2 (5/10). In addition, a stop symbol (one of 0 to 9) is determined in accordance with the normal symbol hit determination numerical value stored in the RAM 27. Note that there are ten types of symbols commonly used for symbols, from “0” to “9”.

Then, the fluctuation time of the ordinary symbol (about 5.0
Second) is set, the hit determination numerical value for the ordinary symbol stored in the RAM 27 is discarded, and the hit determination numerical value for the undetermined normal symbol stored in the RAM 27 is shifted one by one. A space is created so that a hit-determination value for a normal symbol can be stored.

When the interruption process is completed, the symbol change is started on the ordinary symbol display 9, and when the variation time of the ordinary symbol elapses, the changing ordinary symbol is rewritten to the stopped symbol and the variation is stopped. The normal symbol that stopped changing is “1”,
When the hit is "3", "5", "7", or "9", the ordinary electric accessory 5 operates, while the ordinary symbols whose fluctuations are stopped are "0", "2", "4", "4". In the case of the departure of “6” or “8”, the operation of the ordinary electric accessory 5 is not performed.

In the case of the above-mentioned departure, when the stop symbol is displayed, the normal symbol change pause time is set, and the display of the stop symbol on the normal symbol display 9 is maintained until the change pause time elapses. . If the normal symbol change pause time has elapsed and the RAM 27 stores the value for the hit determination for the normal symbol, the next interrupt processing is performed, and then the symbol change is started on the ordinary symbol display 9.

When the operation of the ordinary motorized accessory 5 is performed as a hit, an ordinary symbol change pause time is set when the operation of the ordinary motor accessory 5 is completed. Until the elapsed time, the display of the stopped symbols on the ordinary symbol display 9 is maintained.

Next, the operation of the ordinary electric accessory 5 in the present embodiment will be described. FIG. 38 shows the ordinary electric accessory 5
6 is a timing chart showing processing timings of a CPU 25 regarding processing. The normal symbols stopped changing on the normal symbol display 5 are “1”, “3”, “5”, “7”,
In the case of "9", the ordinary electric accessory 5 operates.

When the normal symbol stops at the above hit symbol,
Normally, the opening time of the electric accessory 5 is set. The opening time of the ordinary electric accessory 5 differs depending on whether the appearance probability of the big hit symbol in the special symbol display device 7 is low or high. In the case of the low probability that the probability variation flag is cleared, about 0.3 seconds is set as the opening time of the ordinary electric accessory 5, while in the case of the high probability that the probability variation flag is set, Normally, about 4.5 seconds is set as the opening time of the electric accessory 5.

When the setting of the opening time of the ordinary electric accessory 5 is completed, a drive excitation signal is output to the ordinary electric accessory solenoid SOL1 to operate the ordinary electric accessory 5 (the start winning opening 8 of the ordinary electric accessory 5). To expand). Then, it is determined whether or not the opening time of the ordinary electric accessory 5 has expired from the time of activation of the ordinary electric accessory 5, and the counting of the detection signal from the start winning detection switch SW1 is started.

When the count of the detection signal from the start winning detection switch SW1 reaches 3 during the opening time of the ordinary electric accessory 5, it means that the opening time of the ordinary electric accessory 5 has not elapsed. Even, usually electric actuated solenoid SOL1
To turn off the drive excitation signal to stop the operation of the ordinary electric accessory 5 (end of the opening of the winning opening 8 of the ordinary electric accessory 5).

If the count of the detection signal from the start winning detection switch SW1 does not reach 3, the ordinary electric accessory 5 operates over the opening time, and when the opening time has elapsed, the ordinary electric accessory solenoid SOL1 is activated. Then, the drive excitation signal is turned off, and the operation of the ordinary electric accessory 5 is stopped.

When the normal electric auditorium pause time is set, the normal electric auditorium pause time (504 ms) is set, and the operation stop state of the ordinary electric auditors machine 5 is maintained until the normal electric auditorium pause time elapses. Note that the opening operation of the ordinary electric auditors product 5 ends at the point in time when the ordinary electric auditorium suspension time has elapsed.

Further, in the embodiment, the symbol display unit for determination which displays the big hit symbol or the off symbol is displayed (the left symbol display unit 1).
2. The right symbol display unit 13 and the middle symbol display unit 14) and the probability switching determination symbol display unit (the symbol display unit 15) for displaying the probability switching identification symbol are displayed in a single display screen (special symbol display). (In the display screen of the device 7), but has a display screen for displaying a big hit symbol or an off symbol, and an information display screen provided separately from the display screen. It is good also as a structure displayed on a display screen.
