A predetermined DC voltage is supplied from the power supply circuit 74 to various circuits and devices of the control circuit 63.

FIG. 6 is a flow chart of the main routine for explaining the operation of the control circuit of FIG. This main routine is executed once every 2 msec, for example. First, in step S (hereinafter simply referred to as S) 1, stack set processing is performed, and in step S2, it is determined whether or not there is a RAM error. This judgment is
This is performed by reading the contents of a predetermined address of the RAM in the basic circuit 64 shown in FIG. 5 and checking whether the value is equal to the predetermined value. Since the data stored in the RAM is indefinite immediately after the program goes out of control or immediately after the power is turned on, the answer to the decision is NO and the control advances to S3. S3
In, the initial data is written in the RAM. At this time, the value set by the probability setting switch 75 is read, and the normal variable display device 4 and the special variable display device 14 are controlled so that specific identification information is displayed with a probability determined thereafter according to the read value. It After that, the control proceeds to S10. Since the initial data is written in S3, the answer to the determination in S2 is YES when the main routine is executed thereafter, and the control directly proceeds to S4.

In S4, data output processing from the input / output port is performed, and control signals are output to the various circuits and devices shown in FIG. Next, in S5, it is judged whether or not there is a 10 count error and whether or not there is a drum error. The 10 count error is, for example, when the specific winning ball detector 22 or the winning number detector 23 is short-circuited or disconnected, and specifically,
When the output signal of the specific winning ball detector 22 or the winning number detector 23 is derived over a predetermined time (for example, 2.9 seconds), or when the special variable winning ball device 17 is opened once, the winning ball is won. When no one is detected, it is determined that there are 10 count errors. The drum error is a case where the rotary drums 46a to 46c (see FIG. 2) are stopped in the middle of rotation or in a state where rotation control is impossible. If there is no 10 count error and no drum error, S6
However, if there is a 10 count error or a drum error, the process proceeds to S9.

At S6, it is determined whether the number of resets is an odd number. The number of resets means the basic circuit 6 according to the reset signal input from the clock reset pulse generation circuit 66 (see FIG. 5) to the basic circuit 64.
4 means the number of times it was reset, and each time it was reset, it was incremented by "0" from "1" until it reached "7",
In this state, "1" is further added to become "0", and the count is incremented again from "0". When the number of resets is 0 or an even number, the special symbol process process by S7 is performed, and when the number of resets is an odd number, the normal symbol process process by S8 is performed and then the process proceeds to S9.

At S9, switch input processing is performed,
Proceeding to S10, a process of updating the random counters of random 1, random 2, and random 4 is performed. The random 1 counter is a counter for the primary lottery for determining whether or not the display result when the special variable display device 14 is stopped is to be a big hit, and the display result of the probability variation variable display 24. It is also a counter for determining a symbol other than the probability variation symbol (delayed symbol) when it is determined not to be a probability variation symbol (hit symbol). The random 2 counter is a random counter for the secondary lottery for determining whether or not the display result when the special variable display device 14 is stopped is to be a big hit, and the display of the probability fluctuation variable display 24. It is a lottery counter for deciding whether or not the result is a probability variation symbol, and is also used as a counter for determining the type of the probability variation symbol to be displayed based on the decision to make the probability variation symbol. Has been done.

The range of values that can be taken by the random 1 counter is 0 to 99, and the number of hit values among them differs between the normal time and the probability improving time. Normally, the number of hits is 4, and when the probability is improved, it is 40. That is, the probability of winning in the primary lottery for deciding whether or not to be a big hit is 10 times higher than usual when increasing the probability. On the other hand, the range of values that the random 2 counter can take is 0 to 659, and the number of hits is 1 to 3 when the probability setting switch is set.
It depends on which of That is, when the probability setting switch 75 is set to 1, the number of hits is 57, when it is set to 2, it is 60, and when it is set to 3, it is 65. To be done.

Therefore, the jackpot probability in software changes in six ways depending on the normal time, the probability improvement time, and the setting of the probability setting switch 75. Of these, the jackpot probability during normal times is as follows. Probability setting switch 7
When 5 is the setting 1, the probability of winning the first lottery is 4/100, and the probability of winning the second lottery is 57/660.
Since both the primary lottery and the secondary lottery are a big hit only in the case of a win, in the case of setting 1, the big hit probability is 4/100 × 57 / 660≈1 / 289.5. Similarly, in the case of setting 2, the probability of winning the second lottery is 60 /
Since it is 660, the jackpot probability is 4/100 x 60/6
60 = 1/275. In the case of setting 3, the probability of winning the second lottery is 65/660, and the probability of jackpot is 4/100.
× 65 / 660≈1 / 253.8.

When the display result of the variable display 24 for variable probability change at the time of the variable stop is the probability improving pattern composed of 3 or 7 grids, the winning probability of the primary lottery is 4 as described above.
/ 100 to 40/100. Therefore, the jackpot probability of each of the settings 1 to 3 is also 10 times.

On the other hand, when performing the above-mentioned random fluctuation symbol lottery using the random 2 counter, there is a probability fluctuation symbol for improving the probability of hitting the special variable display device 14 and the ordinary variable display device 4. The probability of coming out is
The probability variation pattern for the special variable display device 14 and the probability variation pattern for the normal variable display device 4 are set to the same probability, but the probability varies depending on the setting state of the probability setting switch 75. That is, the number of hits is 132 when the setting is 3, and 120 when the setting is 2.
When the number is set to 1, the number is controlled to be 110. Therefore, the probability of becoming a high probability state after a big hit is 132/660 = 1/5 in setting 3 and 120 in setting 2.
/660=1/5.5, setting 1 110/660 = 1 /
It becomes 6.

Due to the above, the special variable display device 14
The average probability that a combination of symbols whose display result is a win is realized is as follows.

In the case of setting 3, 1 / {253.8 × (1-
1/5) + 25.38 × 1/5} ≈1 / 208 In case of setting 2, 1 / {275 × (1-1 / 5.5) +2
7.5 × 1 / 5.5} ≈1 / 230 In the case of setting 1, 1 / {289.5 × (1-1 / 6) +2
8.95 × 1/6} ≅1 / 246 As described above, in any setting state, the display probability is within ± 10% of 1 / 227.56.

The random 4 counter is a random counter for lottery for deciding whether or not the display result when the variable display device 4 is stopped is a hit. The probability of hitting the display result when the variable display device 4 is normally stopped is also changed by setting the probability setting switch 75. The method of controlling the change is as follows.

When the probability setting switch 75 is set to 3, the range of values that can be taken by the random 4 counter is 0 to 44, when it is set 2 it is 0 to 47, and when it is set 1 it is 0. 53. In normal times, only one of the values in the possible range of the random 4 is a hit, but the display result when the variable display 24 for probability fluctuation is stopped is a grid other than 3,7. When the probability improvement pattern is achieved, the hit probability is improved, and 10 of these values are hits. Therefore, in the normal state, the probability that the winning symbol is normally displayed on the variable display device is 1/4 in the case of setting 3.
5, 1/48 for setting 2 and 1/54 for setting 1
Therefore, the setting 3 has the highest probability, and the setting 1 has the lowest probability. When increasing the probability, each of these probabilities increases 10 times.

In the case of the present embodiment, the probability of the special symbol, the ordinary symbol and the probability variation symbol is adjusted by using the same probability setting switch 75, but the special symbol, the ordinary symbol and the probability are adjusted. The probability for each of the fluctuation symbols may be adjusted separately, or only the probability that the display result when the variable display for probability fluctuation 24 is stopped becomes the probability fluctuation symbol may be adjusted. This will be described later with reference to FIG. Further, the probability may be adjusted only for one of the special symbol and the ordinary symbol. Further, the method of adjusting the jackpot probability on software is not limited to the method described above, and any method can be used as a result as long as it can adjust the jackpot probability on software within a predetermined range. Good.

Next, in S11, it is judged whether the number of resets is "0", "4", "1, 2, 3, 5, 6, 7", and if it is "0". In step S12, the output data table is selected and step S15 follows. On the other hand, in the case of "4", the sound data output process in S14 is performed and the process proceeds to S15. According to this S14, the speaker 62 produces the sound effect described later with reference to FIG. When the number of resets is "1, 2, 3, 5, 6, 7", decorative LED and lamp control is performed in S13, and the process proceeds to S15. According to this S13, various lamps and decorative LEDs are display-controlled in the mode shown in FIG.

In S15, the winning prize storage area is stored, and the process proceeds to S16 in which random 1, random 2,
A process of updating the count values of Random 3 and Random 5 is performed. The update process in S16 is performed by using the interval time (for example, 2 msec) of the reset pulse generated from the clock reset pulse generation circuit 66 in S1.
The control operation from S15 to S15 is performed and the reset waiting time after the control operation is performed is repeatedly performed. The random 3 counter is a random counter for determining a stop symbol when the special variable display device 14 comes off. The random 5 counter is usually a random counter for determining a stop symbol when the variable display device 4 comes off. Since there are 16 patterns for each of the three columns, the values that the random 3 counter can take are 0 to FFF in hexadecimal display, that is, 16 ³ possible values.
As for the random 5, normally, three patterns can be displayed in each column of the variable display device 4, so that 3 ³ = 27.
It takes a street value, that is, a value of 0 to 26.

FIG. 7 is a flowchart showing a subroutine program of the normal symbol process processing shown in S8. By S17, the normal symbol process flag is "0",
It is determined whether or not the values are "1 to 3", "5", "4, 6". The normal symbol process flag is a flag necessary for controlling the normal variable display device according to a predetermined order, and is set to "1" by S42 described later, and is incremented by "1" by S49, and by S54. It is set to "5", set to "6" in S57, and set to "0" in S62. Then, when the normal symbol process flag is set to "0", the process proceeds to S18, and a normal process shown in FIG. 9 described later is performed. When the normal symbol process flag is set to "1 to 3", the process proceeds to S19, and each symbol stop process shown in FIG. 10 is performed. If the normal symbol process flag is set to "5", the process proceeds to S20, and FIG.
The pre-opening process shown in 1 is performed. When the normal symbol process flag is set to "4" or "6", the process proceeds to S21, and the control during opening shown in FIG. 12 is performed.

FIG. 8 is a flowchart showing a subroutine program of the special symbol process processing shown in S7. By S22, the value of the special symbol process flag is determined. This special symbol process flag is a flag necessary for controlling the pachinko gaming machine according to a predetermined order, and is set to "1" by S70 described later, set to "2" by S76, and "3" by S75. , S81 sets "4", S87 sets "4", S90 sets "5", S93 sets "6", S98 sets "7", It is set to "9" in S104, set to "10" in S106, set to "11" in S108, and S113.
Is set to "12" by S, set to "0" by S147, set to "13" by S124, and S
118 is set to "14", S134 is set to "16", and S140 is added to "1". When this special symbol process flag is set to "0", the process proceeds to S23, and the normal process shown in FIG. 13 is performed. If the special symbol process flag is set to "1", the process proceeds to S24, and the random 2 check process shown in FIG. 14 is performed. If the special symbol process flag is set to "2", proceed to S25,
The big hit symbol setting process shown in FIG. 15 is performed. If the special symbol process flag is set to "3", the process proceeds to S26, and the outlier symbol setting process shown in FIG. 16 is performed. If the special symbol process flag is set to "4", the process proceeds to S27, and the sub-C shown in FIG.
PU command set processing is performed. If the special symbol process flag is set to "5", the process proceeds to S28, and the sub CPU command output process shown in FIG. 18 is performed. When the special symbol process flag is set to "6-9", the process proceeds to S29, and each drum stop process shown in FIG. 20 is performed. If the special symbol process flag is set to "10" or "11", S
In step 30, the hit check process shown in FIG. 21 is performed. Special symbol process flag is "12" or "13"
If it is set to, the process proceeds to S31, and the processing during opening shown in FIG. 22 is performed. If the special symbol process flag is set to "14" or "15", S
The program proceeds to 32 and the post-opening process shown in FIG. 23 is performed. If the special symbol process flag is set to "16-18", the process proceeds to S33, and the probability variation symbol stop process shown in FIG. 24 is performed.

Next, the flow charts shown in FIGS. 25 and 26 will be described. FIG. 25 is a flowchart showing a subroutine program of the switch input processing shown in S9. FIG. 26 is a flowchart showing a subroutine program of the winning storage area storage processing shown in S15.

Switch port input processing is performed in S148. By this processing, the switch input circuit 72
Detection signals of various detectors are input to the basic circuit 64 via (see FIG. 4). Next, in S149, a 10-count switch error check process is performed, and in S150, a V-switch error check process is performed. This 10-count switch error check becomes an error when the detection signal from the winning number detector 23 (see FIG. 1) is continuously derived for a predetermined time (for example, 2.9 seconds). Similarly, the V switch error check also results in an error when the detection output of the specific winning ball detector 22 (see FIG. 1) is continuously derived for a predetermined time (for example, 2.9 seconds).
Next, in S151, it is determined whether or not there is a 10-count drum error, and if there is, a subroutine program is terminated. This S151 and the above S5
If it is determined that there is an error, the alarm flag is set and an alarm display and an alarm sound are generated (not shown).

When it is determined that there is no error in S151, the process proceeds to S152, and the special symbol starting switch is turned on.
Is determined. In this embodiment, the special symbol starting switch is a starting winning prize that is won in the starting winning prize detector 11 and the starting winning prize 12 of the ordinary variable winning prize winning device (electric prize type starting winning prize) shown in FIG. There is a starting winning ball detector 13 for detecting a ball, and one of the two starting winning ball detectors 11 and 13 is first checked, and when the check is finished, the other winning ball is detected. Check the detector. First, a starting winning prize ball detector 11 provided in the normally variable winning prize ball device 8
The state in which the check is being performed will be described. In a state where no pachinko balls have been won in the normal variable winning ball device 8, the detection signal from the starting winning ball detector 11 is not derived, so that a NO determination is made in S152 and S153.
Then, the corresponding ON counter, that is, the ON counter corresponding to the starting winning ball detector 11 is cleared and S159
Proceed to. This ON counter means that the switch input subroutine program is executed every 2 msec and S1
If the determination of YES is made continuously by 52, "1"
Each is counted up. Pachinko balls usually enter the variable winning ball device 8 and start winning prize detector 11
If detected by S15, a detection pulse having a predetermined pulse width is derived, and S15 is output the number of times corresponding to the pulse width.
The determination of YES is made by 2, and the ON counter is incremented each time. If the value of the ON counter reaches a predetermined value (for example, "3"), YES is obtained in S154.
Is made, and it is determined that a start winning ball has been detected. On the other hand, due to the noise, the starting winning prize detector 1
Even when 1 is erroneously detected, even if the detection signal is instantaneously derived and the determination of YES is made in S152, the detection pulse from the starting winning prize detector 11 will be detected when the switch input subroutine program is executed next time. Since it has already fallen, the ON counter is cleared in S153, the ON counter does not reach a predetermined value (for example, "3"), and a NO determination is made in S154. It is configured so as to prevent erroneous determination of a start winning prize ball due to noise.

If YES is determined in S154, the process proceeds to S155, and it is determined whether or not the special symbol start switch which is turned ON is the start winning prize detector 11 of the electric power start port. If it is the start winning prize detector of the electric power starting port, the process proceeds to S156, the normal electric prize winning number is incremented by "1", and the process proceeds to S157.

In S157, it is determined whether or not the special start memory number has reached the maximum (for example, 4). If not, there is still a margin, so the process proceeds to S158, in which the special start memory number and the start are stored. "1" is added to each of the winning numbers and the process proceeds to S159. On the other hand, if the special start memory number has already reached the maximum (for example, 4), further memory cannot be stored, and therefore a YES determination is made in S157 and the process proceeds to S159 without performing the addition process. Then S1
It progresses to 59 and it is judged whether all the special symbol starting checks are completed, and when it is completed, S16
Although it proceeds to 0, if not finished yet, the procedure proceeds to S152, where the special symbol starting switch, that is, the starting winning prize detector 13 (see FIG. 1) is checked. The check of the starting winning ball detector 13 is also performed in substantially the same way as the checking of the starting winning ball detector 11 of the ordinary variable winning ball device 8 described above, except that the difference is S1.
The point is that the determination of NO is made by 55, and the process proceeds to S157 without performing the addition process of S156.

When all the special symbol starting checks are completed, the process proceeds to S160, and the subsequent normal symbol starting switch check process is performed. As the normal symbol starting switch, in the present embodiment, there are starting passing ball detectors 6a and 6b (see FIG. 1) provided at the starting passing ports 5a and 5b, and one of the starting passing ball detectors is used. After performing the check, the other starting passing ball detector is checked. First, a case where the start passing ball detector 6a is checked will be described. When the pachinko ball does not enter the starting passage opening 5a, the starting passage ball detector 6a is in the OFF state, so the process proceeds to S161, and the corresponding ON counter, that is, the ON state corresponding to the starting passage ball detector 6a. The counter is cleared and the process proceeds to S165. On the other hand, if a pachinko ball passes through the starting passage opening 5a and is detected by the starting passage ball detector 6a, a detection pulse having a predetermined pulse width is derived, and therefore during the period during which the detection pulse is derived. Each time this switch input subroutine program is executed, YE is executed by S160.
The judgment of S is made. Continue to YES by this S160
If the determination is made, the ON counter is incremented each time, and if the counter value reaches a predetermined value (for example, "3"), a determination of YES is made in S162. The processes of S161 and S162 are the same as those of S1 described above.
Similar to the processing of S53 and S154, this is for preventing erroneous determination due to noise, and even if a detection signal is instantaneously derived from the starting passing ball detector due to noise, S162.
This is for making a more negative determination so as not to make an erroneous determination that a pachinko ball has passed.

If YES is determined in S162, the process proceeds to S163, and it is determined whether or not the number of normally started memory reaches the maximum (for example, 4). If not, there is still a margin. To S164, the normal start memory number and the start passing number are each incremented by "1" and S
Proceed to 165. On the other hand, if the normal start memory number has already reached the maximum (for example, 4), further memory cannot be stored, and therefore the process proceeds to S165 without adding. In S165,
It is judged whether or not all the normal symbol start checks are completed, and if it is completed, the subroutine program ends as it is, but if it is not completed, that is, the start passing ball detector 6b is checked. If is not finished yet, the process returns to S160 again, and S160 to S16.
Processing 4 is performed.

Next, a subroutine program of the winning storage area storing process will be described with reference to FIG. S166
Thus, it is determined whether or not the number of starting passes is "0". The number of starting passages is one that is incremented by "1" in S164 and decremented by "1" in S168 described later. If the number of starting passes is "0", S16
9, but if the number of starting passes is not "0", S16
7, the process of storing the value of the random 4 counter (see S10) in the corresponding area of the normal symbol winning storage area is performed, and the process of subtracting "1" from the number of starting passes is performed in S168, and the process returns to S166. Returning, the processing of S166 to S168 is repeated until the number of starting passes becomes "0".
In addition, since the number of starting passages is maximum "2" even if all the normal symbol starting switches are judged to be ON at the same time, the process ends if it is repeated at most twice.

When the number of starting passes reaches 0, the process proceeds to S169, and it is determined whether or not the number of starting winnings is "0". This start winning number is incremented by "1" by S158 and decremented by "1" by S171 described later. When the number of winning prizes for starting is "0", the subroutine program ends as it is, but when it is not "0", S is executed.
Proceeding to 170, a process of storing the values of the random 1 counter and the random 2 counter (see S10) in the corresponding area of the special symbol winning storage area is performed, and after the start winning number is decremented by S171, S169 is performed. Then, the process of S169 to S171 is repeated until the number of winning prizes for starting becomes "0". The number of repetitions in this case is maximum 2 times for the same reason as described above.

Next, the subroutine program of the normal processing shown in S18 will be described with reference to FIG. S34
As a result, the data for turning off the solenoid 10 for the ordinary electric power is set, and the solenoid 10 for the ordinary electric power is controlled to be off based on this data, and the ordinary variable winning ball device 8
The movable wing piece 9 is in the closed second state. Then S35
Then, it is determined whether or not there is a normal symbol winning award memory, and if there is no award winning memory in the ordinary symbol award winning memory area (see FIG. 26S167), the subroutine program ends as it is. Advances to S36, and the processing for subtracting "1" from the normal starting memory number (see S158 in FIG. 25) is performed. Next, proceeding to S37, it is determined whether or not the value of random 4 stored in area 1 of the normal symbol winning storage area (see S167) is a winning value. This normal symbol winning storage area is composed of a plurality of areas so that the value of the random 4 counter can be stored in correspondence with the number of normal starting memory, and the value of the random 4 counter stored in the area 1 is hit. This S37 determines whether or not the value is equivalent to Random 4 in normal times
Only one of the values within the range that the counter can take is determined to be a big hit, but if the probability variation condition for improving the hit range of the random 4 counter is satisfied by S144 and S145 described later, it is random. Any of the 10 types of values that can be taken by the 4 counter is judged as a big hit. As a result, when the probability is improved, the probability of a big hit is 10 times higher than in the normal time. S3
If it is determined to be a big hit by 7, the process proceeds to S38, and the left symbol = middle symbol = right symbol is set in accordance with the value for the left symbol of the random 5 counter, and the process proceeds to S42. This S
Normally, the variable display device 4 is stopped and controlled by 38 so that the variable display device 4 has predetermined identification information (for example, a certain pattern of the symbols 3, 7, and F).

On the other hand, if it is determined in S37 that it is not a big hit, the process proceeds to S39, the symbols are set according to the count value of the random 5 counter, the process proceeds to S40, S3
It is determined whether or not the symbol set by 9 is left = middle = right, and if not, the process proceeds directly to S42. On the other hand, if left = middle = right by accident, normally the symbols when the variable display device 4 is stopped will be an unbalanced pattern and a combination of the symbols will be hit. Only the symbols are added by "1" and the symbols are forcibly shifted, and the symbols are controlled so as not to be seen.

At S42, the normal symbol winning storage area is set to 1
The process of shifting each is performed. For example, the data stored in area 1 may be erased and the data stored in area 2 may be shifted to area 1 and stored instead, and the data stored in area 3 may be shifted to area 2. The storage area is shifted one by one such that the data stored and stored in the area 4 is shifted to the area 3 and stored. Next, by S43, the ordinary pattern LE
The D timer is cleared, the stored basic time is set in the process timer A, and the process for setting the normal symbol process flag to "1" is performed. This normal pattern L
The ED timer is usually for controlling the variable speed of the symbol of the variable display device 4. In addition, "basic time" is S4
5 or the time stored in S46. The "process timer A" is for measuring various control times required for controlling the normal variable display device and the normal variable winning ball device. Next, the routine proceeds to S44, where the normal start memory number (see S164 and S36 in FIG. 25) is "2".
Whether or not it is above is determined. If it is above, the basic time reduction is selected and stored in S46, and "2" is set.
If it is less than, a process of selecting and storing the basic time standard is performed in S45. This basic time is the time from the variable start of the variable display device to the transition to the stop control, which is about 1.7 seconds when the basic time reduction is selected, and the basic time standard is selected. If it is done, it takes about 5 seconds.

Since the normal symbol process flag is updated to "1" by S43, each symbol stop program shown in S19 is executed when the next normal symbol process process is performed. The subroutine program of each symbol stop process is shown in FIG. 10, and the normal symbol LED rotation process is performed in S47, and it is determined in S48 whether the process timer A has ended. If it is not finished yet, the subroutine program is finished as it is, and when the next normal symbol process process is executed, the process of S19 is performed because the normal symbol process flag remains "1", and S47 is executed. The normal symbol LED rotation process by is continuously performed. This normal pattern L
The ED rotation processing is executed until the process timer A ends in S48, and if the process timer A ends, S49.
Then, the control proceeds to the stop control of the ordinary variable display device.

First, in S49, the display symbol = stop symbol is set, and in S50, the normal symbol process flag is incremented by "1" and the process proceeds to S51. As a result, the left symbol first stops. In S51, it is determined whether or not the normal symbol process flag is "4". At this stage, since the normal symbol process flag should be "2", a NO determination is made and the process proceeds to S52, the symbol stop waiting time is set in the process timer A, and the subroutine program ends. This symbol stop waiting time is about 0.
It takes about 4 seconds. In the next execution of the normal symbol process processing, each symbol stop processing of S19 is performed because the normal symbol process flag is "2", and S
The normal symbol LED rotation process by 47 is continuously performed, and if the symbol stop waiting time set in S52 ends, YES is determined in S48 and the processes of S49 and S50 are performed. At this stage, the middle symbol is stopped and the normal symbol process flag becomes "3". Therefore, the determination of NO is made in S51, and the process proceeds to S52. Furthermore, in the next execution of the normal symbol process process, since the normal symbol process flag is "3", each symbol stop process of S19 is executed again, and the rotation process of the normal symbol LED by S47 is continuously performed. S48, S49, S50
Is processed. As a result, the right symbol stops and the normal symbol process flag becomes "4", so that a YES determination is made in S51, the process proceeds to S53, and the process timer A is set to the waiting time. This disconnection waiting time is about 1 second. Next, by S54, it is determined whether or not the left symbol = the middle symbol = the right symbol, and when the determination is NO, the subroutine program ends as it is. On the other hand, if left symbol = middle symbol = right symbol, S5
Go to 5, update the normal symbol process flag to "5",
The release waiting time (about 0.5 seconds) is set in the process timer A.

When NO is determined in S54, since the normal symbol process flag is "4", the next time the normal symbol process process is executed, S is performed.
The open processing program 21 is executed. The subroutine program of the open processing of S21 is shown in FIG. Normal design process flag is "4" by S59
Since it is "4", S6 is performed.
In step S2, it is determined whether the process timer A set in S53 has ended. If not, the subroutine program ends. Even in this state, since the normal symbol process flag remains “4”, the determination of YES is made in S59 and the process timer A is ended in S62 also when executing the next normal symbol process process. Judgment is made. Then, the loop of S59 and S62 is circulated until the end, and at the end stage, the process proceeds to S63, in which the normal symbol process flag is updated to "0". As a result, when the next normal symbol process process is executed, the process proceeds to the normal process shown in S18.

On the other hand, if YES is determined in S54, since the normal symbol process flag is updated to "5", the next time the normal symbol process process is executed, before the opening shown in S20. The processing program is executed. The pre-release processing subroutine program is
It is shown in FIG. In S56, it is determined whether or not the process timer A set in S55 has ended. If not, the subroutine program ends. Then, when the process timer A ends, the process proceeds to S57, the normal electric winning combination winning number is cleared, and the process proceeds to S58. This normal electric prize winning number is a value that is incremented by "1" in S156, and the number of winning balls that have won in the normal variable winning ball device 8 is counted, and the prize is won in the normal variable winning ball device 8 once. This is necessary to determine whether or not the maximum number of possible hit balls has been reached. S58
Then, the normal symbol process flag is updated to “6”, and the process timer A is set to the normal electric power release time (for example, 5.9 seconds).
Is set.

At the next execution of the normal symbol process processing, since the normal symbol process flag is updated to "6" at S58, the open processing program at S21 is executed. As a result, the process proceeds to S59, and it is determined whether or not the normal symbol process flag is "4". Since the normal symbol process flag is "6", the process proceeds to S60, and the solenoid 10 for the normal electric power combination is performed. Data for turning ON (see FIG. 1) is set. The data set in S60 and the electric power release time (5.9 seconds) set in S57 are output to the solenoid 10 for the normal electric power in accordance with S4.
Is excited and the movable wing piece 9 of the normally variable winning ball device 8 is opened for a maximum of 5.9 seconds. Next, the process proceeds to S61, where it is determined whether or not the maximum number (6) of normal electric prize winning combination has been reached. If not, the process proceeds to S62, but if it has reached, the process proceeds to S63. The normal symbol process flag is updated to "0". As a result, the next time the normal symbol process processing is executed, the normal processing process of S18 is executed.
As a result, the solenoid 10 of the normal electric power is turned on by S34.
The data for setting FF is set, and the normal variable winning ball device 8 is switched to the second state in which it is closed. This S60,
By S24, drive control means for driving and controlling the ordinary variable winning ball device to the first state when the display result when the ordinary variable display device is stopped becomes predetermined identification information is configured. There is.

Next, the subroutine program of the normal processing of the special variable display device shown in S23 will be described with reference to FIG. By S64, it is determined whether or not there is a winning memory in the special symbol winning storage area (see S170 in FIG. 26), and if not, the process proceeds to S65 and the primary lottery flag is set to "out". The determination as to whether or not the special variable display device 14 has hit is 1 based on the value of the random 1 counter.
Only when the two lottery results of the next lottery and the second lottery based on the value of the random 2 counter are both successful, the big hit is determined, and therefore, the result of the first lottery is stored. The primary lottery flag is required. If there is a special symbol winning storage, the process proceeds to S66, where the value of the random 1 counter stored in the area 1 of the special symbol winning storage area and the current value of the random 1 counter are added, and the addition result is a hit. It is determined whether or not the value becomes. At this time, the number of values per hit is determined to be 4 out of 0 to 99 in normal times and 40 in probability improvement.

Next, in S67, it is determined whether or not the result of the primary lottery is a win, and if it is determined that the result is a win, the primary lottery flag is set to "win" in S69. If it is determined that it is off, S68
The process of setting the primary lottery flag to “out” is performed. Next, in S70, the special symbol process flag is updated to "1" and the subroutine program ends. When the special symbol process process is executed next time, the random 2 check process in S24 is performed because the special symbol process flag is set to "1".

The subroutine program of the random 2 check process is shown in FIG. 14, and it is judged in S71 whether or not the primary lottery flag is set to "win", and it is not set to "win". In case S7
Go to step 5, but if it is set to "hit" S7
2, the value of the random 2 counter stored in the area 1 of the special symbol winning storage area is determined, and in S73, it is determined whether or not the determination result of the secondary lottery is a winning. When it is determined that it is not, the process of setting the primary lottery flag in S74 to "out" is performed, and the process of setting the special symbol process flag to "3" is performed in S74. The number of hits at this time is 57 when the probability setting switch 75 is set to 1 out of the values in the range of 0 to 659 which can be taken by the random 2 counter.
The number is set to 60 in the case of setting 2, and 65 in the case of setting 3.

Next, in S77, the number of special starting memory (see FIG.
5 S158) is subtracted by "1", and S7 is executed.
8, the processing for shifting the data stored in the special symbol winning storage area one by one is performed, and the subroutine program ends. The process of shifting the special symbol winning storage area is the same as the process of S42 described above. At the next execution of the special symbol process process, the special symbol process flag is set to "3", so the process of the deviating symbol set in S26 is performed.

On the other hand, if it is determined in S73 that the result of the secondary lottery is winning, the process proceeds to S76, in which the big hit symbol number is set based on the remainder value obtained by dividing the current value of the random 2 counter by 18, and the special symbol. The process flag is set to "2" and the process proceeds to S76. Thus, the remainder value obtained by dividing the random 2 counter by 18 is 1 from 0 to 17
There will be 8 different values, which will correspond to 18 different jackpot symbol combinations.

As a result of the processing of S76, at the next execution of the special symbol process processing, the special symbol process flag is set to "2" so that the big hit symbol setting processing of S25 is executed. A subroutine program for this big hit symbol set is shown in FIG. S
By 79, the big hit symbol is set by the big hit symbol number. This big hit symbol number corresponds to a combination of 18 kinds of big hit symbols as described above, and a stop symbol number that becomes a big hit according to the value is set. This stop symbol number is the number shown in the leftmost column shown in FIG. Next, by S80, the winning row LE
While the D data is set, the jackpot flag is set to "reach" and "jackpot". The hit row LED data set by S80 is S4.
Accordingly, the hit row display LEDs 16 (see FIG. 1) are output, and the hit row display LEDs 16 located at both ends of the hit row in which a combination of specific identification information is arranged are display-controlled. Then S8
1, the special symbol process flag is set to "4". As a result, when the special symbol process process is executed next time, the process of the sub CPU command set shown in S27 is performed. The subroutine program of this sub CPU command set is shown in FIG.

In S88 of FIG. 17, a command is set to the sub CPU. This command is
As shown in FIG. 9, it is temporarily stored in the sub CPU command area on the basic circuit 64 side. The specific contents of the stored data are, as shown in FIG. 19, a header indicating the start of command output, a command for specifying whether the rotary drums 46a to 46c are in normal rotation or abnormal recovery, left stop It is a symbol, a middle stop symbol, a right stop symbol, a big hit flag, and a drum control flag. It should be noted that the above-mentioned abnormality recovery means the rotation of the rotary drum after an abnormality has occurred in the special variable display device 14, which is repaired by an attendant in the game hall. Further, the drum control flag includes S89 in FIG.
Accordingly, the number of winning prizes stored in the special symbol winning prize memory area is set. When the number of winning prizes stored is "1" or more, the shortening mode is set to shorten the basic time from the start of the variable variable display device to the stop control. In addition,
As a condition for setting the basic time into the shortened mode, the condition that the normally variable display device is in the probability improving state may be added to the condition. That is, the variation time may be shortened only when the probability is improved. Next, in S90, the special symbol process flag is set to "5". As a result, at the next execution of the special symbol process process, the process of sub CPU command output shown in S28 is performed. This sub C
The PU command output subroutine program is shown in FIG.

By S91, the sub CPU command output is set. This output is the data stored in the sub CPU command areas 0 to 6 on the basic circuit 64 side shown in FIG. 19, one by one each time S90 is executed, and the sub CPU on the motor drive / sensor circuit 73 side. Output to the command input area. Since this S90 is executed once every 4 msec, 28 msec is required to transmit all 7 types of data stored in the storage areas 0 to 6.
Will need time. In addition, the sub CPU checks the input of the command data on the basic circuit side by 2 mse.
It is executed once for each c. Then, if the input command data is 1F, it is determined that the command has started, and the command data from the next time onward is stored as valid data in the corresponding sub CPU command input area every 4 msec. Then, by S92 of FIG.
It is determined whether or not the command output is completed, and when all command outputs are completed, the process proceeds to S93, the special symbol process flag is set to "6", and the process timer B is set to the left stop basic time. The processing for setting the drum reference rotation speed is performed and the subroutine program ends. The left stop basic time set in this process timer B is the time from the start of the variable variable display device 14 to the start of shifting to the stop control of the left symbol, and about 2 in the case of the shortened mode described above. It is about 7 seconds and about 6 seconds in the standard mode which is not the shortening mode. The drum reference number of revolutions is for determining the number of revolutions of each of the rotating drums 46a to 46c of the special variable display device 14, and is 12 revolutions in the standard mode, and is, for example, in the shortening mode. It becomes 4 rotations. At the next execution of the special symbol process processing, since the special symbol process flag is set to "6" in S93, each drum stop control shown in S29 is performed.

On the other hand, if it is determined in S73 that the result of the secondary lottery is off, the special symbol process flag is set to "3" in S75, so that the next time the special symbol process process is executed. Is set in step S26 for the removal symbol. FIG. 16 shows a subroutine program for setting this off pattern.

By S82, the deviation symbol is set based on the value of the random 3 counter. At this point, the jackpot flag is cleared. By S83, it is determined whether the set left symbol and the right symbol are the same symbol. If they are not equal, the process proceeds to S87, but if they are equal, S84.
Will set the LED data for each row, and
The jackpot flag is set to "reach". Then S85
Proceed to, it is determined whether or not the left symbol = middle symbol = right symbol, and if NO is determined, the process proceeds to S87, but if the left symbol, the middle symbol, and the right symbol happen to be equal, In S86, a process of adding only the middle symbol by "1" and shifting is performed. This is a process performed when the symbols set by chance happen to be the same on the left side, the middle side and the right side, even though it is judged to be off by S73 as a result of the first lottery and the second lottery, in which case In that, the middle pattern is forcibly displaced to make it a deviating pattern. Next, by S87, the special symbol process flag is set to "4".

In the next special symbol process processing,
Since the special symbol process flag is set to "4", the processing of the sub CPU command set shown in S27 is performed.

Next, when the special symbol process flag is set to "6", each drum stop control shown in S29 is performed, and the subroutine program of each drum stop control is shown in FIG. ing. S94
Thus, the motor step check process is performed. The motor step check is a process of incrementing the drum rotation speed counter by "1" each time the drum sensors 51a, 51b, 51c shown in FIG. 2 are turned on. Next, in S95, it is determined whether the process timer B has expired. This process timer B is
It is a timer necessary for timing various display control times of the special variable display device 14, and is S98, S102, S
104, S113, S106, S108, S113, S
Each time is set by 118. When it is determined that the process timer B has expired, the process proceeds to S96, and the drum stop sound is set. This set drum stop sound is output to the speaker 62 in accordance with S4,
A drum stop sound is output from the speaker 62. Then S9
7, it is determined whether or not the special symbol process flag is set to "6". Since it is currently set to "6", the process proceeds to S98, where the special symbol process flag is "7". And the process timer B is set to the right drum stop time. This right drum stop time is the same for each rotary drum 46a to 46c on the left,
The stop delay time required to stop by shifting the time in the order of right and middle is about 0.6 seconds.

Even when the special symbol process flag is set to "7" by S98, each drum stop process of S29 is performed at the next execution of the special symbol process process as shown in FIG. In that case, a judgment of NO is made in S97, a judgment of YES is made in S99, and a judgment of whether or not there is a drum error is made in S100. This drum error means, when the rotating drum is stopped during rotation or becomes uncontrollable as described above, specifically, the reference rotation speed set in S93 and the drum rotation speed counted in S94. Does not match. In that case, a drum error is set in S101, an alarm is issued, and control is performed when a predetermined abnormality occurs. Next, if the drum error has not occurred, the process proceeds to S102, the special symbol process flag is set to "8", and the process timer B is set to the medium drum stop time (about 0.6 seconds). Be done.
Next, in S103, it is determined whether or not the jackpot flag is set to "reach". This "reach" is set by S80 and S84, and is a display state in which there is a possibility that a big hit state will occur when the left rotating drum 46a and the right rotating drum 46c are stopped. Means the case. If it is not set to "reach", the subroutine program ends as it is. Even in that case, since the special symbol process flag is set to "8", each drum stop control of S29 is performed again. On the other hand, if the big hit flag is set to "reach", the process proceeds to S104, the special symbol process flag is set to "9", and the reach operation time is set to the process timer B. This reach operation time is about 3 seconds to 5 seconds. The special symbol process flag is set to "10" or "11" as described later for the first time after the reach operation time set in this process timer B ends, and each drum stop control ends and the rotation of all the drums ends. It will be stopped. Therefore, when the big hit flag is set to "reach", the central rotating drum continues to rotate for about 3 to 5 seconds even after the left and right rotating drums have stopped. This reach operation time is 16 kinds of time depending on the type of the stop symbol because there are 16 types of symbols of the central rotating drum.

When the next special symbol process processing is executed and it is determined in S95 that the process timer B has ended, the processing of S96, S97, S99, S105 is performed, and the big hit flag is set to "big hit". If not, the process proceeds to S106, the process of setting the special symbol process flag to "10" is performed, the process timer B is disconnected and the waiting time (about 1 second) is set, and the subroutine program ends. When executing the next special symbol process processing, the special symbol process flag is "10"
Since it is set to, the hit check process shown in S30 is performed.

On the other hand, when it is determined in S105 that the big hit flag is set to "big hit", S10
Then, the process proceeds to 7 and the process of setting the hit range of the random 1 counter and the random 4 counter to a normal value in the hit determination is performed. That is, in the present embodiment, the probability improving state ends when a big hit occurs in the special variable display device. As a result, in the case of the hit failure determination in S37, only one of the values in the range that the random 4 counter can take is determined as the big hit. Further, in the case of judging the hit / miss in S67,
Only four values out of the possible range of values of the random 1 counter will be judged as a win. Next, in S108, the special symbol process flag is set to "11",
The time before the first opening (about 4 seconds) is set in the process timer B, and the subroutine program ends. If the special symbol process flag is set to "10", "11", when executing the next special symbol process process, S
The hit check process shown in 30 is performed.

The subroutine program for the hit check is shown in FIG. In S109, it is determined whether the process timer B has expired. Then, at the end stage, the process proceeds to S110, the output data for turning off the stepping motor for rotating the rotary drum is set, and the process proceeds to S111, where it is determined whether or not the big hit flag is set to "big hit". "Big hit"
If it is set to, the special symbol process flag is set to "12" in S113, the opening time (30 seconds) is set to the process timer B, the opening number counter is updated to "1", and the subroutine program Ends. Since the special symbol process flag is set to "12" by this S113, the control during opening shown in S31 is performed at the time of the next execution of the special symbol process processing. On the other hand, when it is determined in S111 that the big hit flag is not set to "big hit", S11
2, the special symbol process flag is set to "0". As a result, when the special symbol process process is executed next time, the normal process program shown in S23 is executed.

FIG. 22 is a flow chart of the open process performed in S31 of FIG. In S114, the big hit information output to the hall computer and the data for turning on the solenoid 20 for driving the opening / closing plate 19 (see FIG. 1) of the special variable winning ball device are set. In S115, the V switch and 10 count switch check processing is performed. This process is performed in the specific winning area 21.
This is a process for determining whether or not there is a winning ball (see FIG. 1) and whether or not there is a winning ball in the winning area 18, the details of which will be described later with reference to FIG. Subsequently, in S116, as a result of the processing in S115, it is determined whether or not the number of the pachinko balls that have won in the winning area 18 has reached a predetermined maximum number. If the winning number is not the maximum, the process proceeds to S117, and the special variable winning ball device 17 is set to the first
Maximum time to keep in the state (for example, 30 seconds)
Is determined whether or not the process timer B for determining whether or not has expired. Process timer B
If is not yet finished, there is a margin in both the number of winning prizes and the opening time, and this subroutine is finished as it is. If it is determined in S116 that the number of winning prizes is the maximum, or if it is determined in S117 that the process timer B has ended, the process proceeds to S118, and it is necessary to change the special variable winning ball device 17 to the second state. The special symbol process flag is set to 15, and the process timer B is set to a value corresponding to the V reception time. V
The reception time means that there may be a pachinko ball that is late in winning in the specific winning area 21 even after the special variable winning ball device 17 is in the second state, so the specific winning area 2 within the V receiving time is
This is the time for which the winning of a pachinko ball in 1 is valid, for example, about 2 seconds. After S118, this subroutine ends.

FIG. 23 is a flow chart showing a subroutine program of post-opening processing shown in S32.

By S119, output data for turning off the solenoid is set, the set data is output according to S4, the excitation of the solenoid 20 is released, and the variable winning ball device 17 is closed, which is disadvantageous to the player. To the second state. Next, in S120, the V switch (specific winning ball detector 22) and 10-count switch check processing is performed, and in S121, it is determined whether or not the process timer B has expired. The S
The specific content of the process of 120 is shown in FIG.

In S172 in FIG. 27, it is determined whether or not it is time to determine that the V switch is ON. This processing is performed by the basic circuit 64, for example.
V input from the switch input circuit 72 (see FIG. 5)
The detection output value from the switch (specific winning ball detector) 22 is checked once each time this subroutine is performed, and when it is determined to be ON a predetermined number of times (for example, 3 times) continuously, the V switch is ON. It is done by judging that there is. By doing so, even if the signal given to the basic circuit 64 temporarily has a value indicating ON due to noise or the like, in such a case, OFF is again shown in the next check. Since the value returns to the value, noise does not cause an error in the determination as to whether the V switch is ON. If the V switch is not ON timing, the process directly proceeds to S177, but if it is determined that the V switch is ON, the process proceeds to S173, the winning number counter is incremented by 1, and S1
Proceed to 74. In S174, it is determined whether or not the number of times the special variable winning ball device 17 is opened is maximum (for example, 16 times). If the number of times of opening is the maximum, it is not necessary to continue opening, and thus the winning of the V switch is invalidated. That is, if the number of releases is the maximum as a result of the determination in S174, the control directly proceeds to S177. If the number of times of opening is not yet the maximum, it is necessary to continuously open the special variable winning ball device 17. Therefore, first in S175, it is determined whether or not the V winning flag is already set. If the V winning flag is already set, the process directly proceeds to S177, but if not set, the process proceeds to S176, the special symbol process flag is incremented by 1, the V winning flag is set, and the sound at the time of V winning is set. The data is set, and the process proceeds to S177. In S177, it is determined whether or not the 10-count switch is ON timing. This judgment is also V switch ON
The same method as the timing (S172) is performed.
If the 10-count switch is not ON, this subroutine ends directly, but if it is ON, S178.
Then, the process ends after adding 1 to the winning number.

Next, returning to the flowchart of FIG. 23, when the V reception time is set in the process timer B in S118, it is determined in S121 whether or not the V reception time has expired, and the V reception time is determined. When the reception time is over, the process proceeds to S122, and it is determined whether or not the V winning flag is set. This V winning flag is set in S176, which will be described later, and the pachinko ball has a specific winning area 21 (see FIG. 1) between the opening of the variable winning ball device and the end of the V reception time after closing. (See), the V winning flag is set.

If the V winning flag is set, the process proceeds to S123, it is determined whether the number of times of opening is the maximum, and if it has not reached the maximum number, the process proceeds to S124, the special symbol process flag. Is updated to "13", the open time is set in the process timer B, the open counter is incremented by "1", and then the process proceeds to S135. On the other hand, when the number of times of opening reaches the maximum or when the V winning flag is not set, the process proceeds to S125, the opening number counter is cleared, the big hit information is set to OFF output, and 1 is set.
Processing for clearing the next lottery flag is performed. That is,
When the V winning flag is not set, the repeat continuation control for repeatedly continuing the variable winning ball device to the first state again is not performed, and even when the V winning flag is set. However, if the number of times of opening has already reached the maximum, the repeat continuation control is not performed any more, and therefore the process of S125 is performed. Next, in S126, the current count value of the random 2 counter is determined, and in S127, the count value is set to a high probability state in which the probability that the display result when the special variable display device 14 is stopped is a winning symbol is improved. A judgment is made as to whether or not the value has been set to start. If YES is determined, the process proceeds to S128, and the probability variation variable display 2
The processing of setting both the left and right of the stop symbol of 4 (see FIG. 1) to the grid of either 3 or 7 is performed S135.
Proceed to. On the other hand, whether the count value of the random 2 counter as a result of the determination in S126 is a value that starts a high-probability state that improves the probability that the display result when the normally variable display device 4 (see FIG. 1) is stopped is a hit. It is determined whether or not, and if so, the process proceeds to S130, in which both the left and right of the stop symbol of the variable display for probability variation 24 are 0, 1,
The process of setting any one of 2, 4, 5, 6, 8, 9 is performed and the process proceeds to S134. That is, when the display result of the variable display 24 for probability fluctuation at the time of stop is "33" or "77", the special variable display device 14 is controlled so that a big hit occurs with a high probability. The display result when the variable display 24 for probability fluctuation is stopped is "0.
0 ”,“ 11 ”,“ 22 ”,“ 44 ”,“ 55 ”,“ 6 ”
If the value is "6", "88", or "99", the variable display device 4 is normally controlled so that a big hit occurs with a high probability.

Next, as a result of the determination in S126, if it is neither the special symbol high probability start value nor the normal symbol high probability start value, by S131, the variable display for probability variation according to the current count value of the random 1 counter. Twenty-four stop symbols are set. In addition, since the value that the random 1 counter can take is 0 to 99, the variable display for probability variation 2
This corresponds to the total number of combinations of four stop symbols.
Then, as a result, if the left symbol and the right symbol happen to be the same, a YES determination is made in S132, and the right symbol is forcibly shifted by "1" in S133, and the left symbol and the right symbol match. Controlled not to. Next, in S134, the probability variation symbol LED timer is cleared, the process timer B is set to the left stop basic time, and the special symbol process flag is updated to "16". This probability fluctuation symbol LED timer is for timing the time required when sequentially controlling the variable display of the probability fluctuation symbol LED, and once before the probability fluctuation symbol LED starts rotating display by S138 described later. Cleared. The left stop basic time set in the process timer B is, for example, about 2 seconds, and when the stop basic time elapses, the control shifts to stop control of the left stochastic fluctuation symbol LED in the stochastic fluctuation variable display. Next, in S135, it is determined whether or not the number of winning balls that have won the variable winning ball apparatus is "0". If not, the process proceeds to S137, where the winning number and the V winning flag are cleared. Processing is performed. On the other hand, the fact that no pachinko balls are won during the opening of the variable winning ball device means that the 10-count switch for detecting the winning pachinko balls in the variable winning ball device may be defective or fraudulent. Therefore, in such a case, the process proceeds to S136 and 10
After the count error setting process is performed, S137
Proceed to.

Since the special symbol process flag is set to "16" by S134, the subroutine program of the stochastic fluctuation symbol stop processing shown in S33 is executed at the next execution of the program. The subroutine program of this probability variation symbol stop processing is shown in FIG. 24, and first, the probability variation symbol LED by S138.
Is rotated to variably display the probability variation variable display 24 (see FIG. 1). Next, in S139, it is determined whether the process timer B has expired. This process timer B, the left stop basic time is set according to S134, the process proceeds to S140 at the stage when the set left stop basic time ends, and the display symbol displayed by the probability variation symbol LED is the S128. Alternatively, the stop symbol set in S130 or S131 is displayed as the stop symbol, and the special symbol process flag is incremented by "1". Next, proceeding to S141, it is determined whether or not the special symbol process flag is "18". At this stage, the special symbol process flag is "1.
Since it is 7 ”, the process proceeds to S142, and the process timer B is set to the symbol stop waiting time. This symbol stop waiting time is a waiting time for stopping the right symbol after a predetermined time has elapsed after the left symbol stopped, and is, for example, about 0.5 seconds.

At the next execution of the program, S
At 139, when the symbol stop waiting time set in the process timer B ends, the process proceeds to S140. As a result, since the right symbol is stopped and the special symbol process flag is incremented by "1", the special symbol process flag becomes "18", and the process proceeds to S143. In S143, it is determined whether or not the left symbol and the right symbol displayed by the probability variation symbol LED match, and if they do not match, the special symbol process flag is updated to "0". As a result, when the program is executed next time, the process proceeds to S23. On the other hand, when the left symbol and the right symbol match, the process proceeds to S144, and it is determined whether or not the left symbol is "3" or "7". When the left symbol is "3" or "7", the symbol displayed on the variable display for probability variation is "33" or "77". In that case, the process proceeds to S146, and the process of changing the hit range of the random 1 counter to the above-described high probability value is performed. As a result, the probability that the display result when the special variable display device is stopped is a winning symbol is improved ten times. On the other hand, if the left symbol is other than "3" and other than "7", that is, 0,
If it is any one of 1, 2, 4, 5, 6, 8, and 9, the process proceeds to S145, and a process of changing the hit range of the random 4 counter to the above-described high probability value is performed. As a result, the probability that the display result when the variable display device 4 (see FIG. 1) is stopped normally becomes a winning symbol is improved ten times. Although not described in the processing of S145 or S146, the hit sound data is set to notify the player from the speaker 62 that the probability has been improved (sound effect J in FIG. 28). Next, proceeding to S147, the special symbol process flag is updated to "0". S126-S130, S143-
By S146, the probability varying means is configured to vary the probability that the display result of the variable display section becomes the specific identification information when the display result of the display section becomes the predetermined identification information.

FIG. 28 is a diagram showing a table showing the display modes of various display devices which are display-controlled according to various game states and the types of sound effects emitted from the speakers.

The leftmost column in FIG. 28 shows the operating state of the pachinko gaming machine. To explain in order from the top, when the power is turned on, when the pachinko balls pass through the starting opening, that is, the starting passing opening 5a, When the pachinko ball passes to 5b, after the normal symbol, that is, the normal variable display device 4 is stopped (in the case other than hit), before the normal electric role, that is, the normal variable winning ball device 8 is opened, when the normal electric role is opened, the pachinko ball At the time of winning the starting opening, that is, the ordinary variable winning ball device 8 for the pachinko ball and the starting winning opening 12
At the time of winning the prize, at the time of reaching, after the special symbol, that is, the special variable display device 14 is stopped (in the case other than the big hit), before opening the variable winning ball device 17 in the big hit state, the pachinko ball to the specific winning opening 21 in the big hit state. Before winning the prize, after winning the pachinko ball to the specific winning opening 21 in the big hit state, and after opening the variable winning ball device 17 in the big hit state.

In FIG. 28, (a), (a ') and (b) are
The figure shows the types of blinking display states of various display devices such as the decorative LED (B) and the V display LED 26. That is,
(A) shows 128 after turning off for 128 ms
This means that the blinking control is performed at the timing of turning on for only ms, and (a ') means that the blinking control is performed at the timing of turning on for 128 ms and then turning off for 128 ms. (B) is 256m
The blinking control is performed at the timing of turning on for s and then turning off for 256 ms.
It turns off for only 56ms, and then O for 256ms
This means that blinking control is performed at the timing of entering the N state. (C) is in the ON state only for 512 ms, then 15
This means that the blinking control is performed at the timing of being in the OFF state for 36 ms. (D) means that flicker control is performed with 1024 ms as one cycle. (E) is 51
This means that the blinking control is performed at the timing when it is turned on for 2 ms and then turned off for 512 ms.
(F) is turned off for 768 ms, and then 256
This means that the blinking control is performed at the timing of being turned on for ms. (F ') means that the blinking control is performed at the timing when the ON state is first set for 256 ms and then the OFF state is set for 768 ms.

The "probability improvement" in the row of the rail decoration lamps 41 means the probability improvement time in which the probability that the stop symbol is won is improved in S145 or S146. “At the time of probability improvement” in the sequence of sound effects of the speaker 62
Is the same meaning. It should be noted that the sound effect J is generated only during a certain period when the probability is improved, and the rail decoration lamp 41 blinks during the period when the probability is improved.

When the operating state is a winning opening winning combination, the hit row display LED 16 is display-controlled so as to turn on and turn with 256 ms as one cycle. At the time of the reach, only the LEDs located at both ends of the hit row in which the winning symbol combinations may be established are blinked and displayed in the manner of (a ′). Even in the big hit state, only the LEDs located at both ends of the hit row in which the combination of the symbols of the big hits are established are controlled to blink in the manner of (a ').

The V display LED 26 blinks in the manner of (b) after the winning of the pachinko ball to the specific winning opening in the big hit and the opening of the variable winning ball device. In the final round, the display VLED 26 is not subjected to any display control. Speaker 62
As shown in the figure, 10 types of sound effects A to J are emitted according to the respective operating states. It should be noted that the type B sound effect that is produced during the variable display of the special variable display device based on the winning opening prize of the pachinko ball is the stop of each symbol of the special variable display device 14 that is variably displayed based on the starting prize. Occurs only at times. Further, the G-type sound effect emitted after the winning of the pachinko ball to the specific winning opening in the jackpot is made only when the pachinko ball first wins the specific winning opening 21 in one opening. Further, the G-type sound effect is not emitted in the final round of the repeat continuation control of the variable winning a prize ball device 14. In addition, when the probability is improved, the winning number display 25 (see FIG. 1) blinks “F”. The blinking is controlled to be turned off at a timing of first turning off for 256 ms and then turning off for 256 ms.

Incidentally, in FIG. 28, "probability improvement" is displayed both when the probability of the special symbol is improved and when the probability of the ordinary symbol is improved, but these are separated and the special symbol is displayed. The manner of notification may be different when the probability is improved and when the probability of the normal symbol is improved.

Another embodiment of the present invention will be described next. Figure 2
9 is a rear view of a pachinko gaming machine 100 having three types of probability setting switches 75A, 75B, and 75C, unlike the pachinko gaming machine shown in FIG. FIG. 28
4 and FIG. 4, the same parts are designated by the same reference numerals. Probability setting switch 75A shown in FIG.
Is a probability setting switch for special symbols, probability setting switch 75B is a probability setting switch for normal symbols,
The probability setting switch 75C is a probability setting switch for a probability variation pattern. Thus, the probability setting switch 75A, 7 for each of the special symbol, the ordinary symbol and the probability variation symbol
By separately providing 5B and 75C, the setting of the probability of the special symbol, the setting of the probability of the normal symbol, and the setting of the probability of the probability variation symbol may be performed separately.

The probability variation condition between the special symbol and the ordinary symbol is:
At least if the display symbols of the variable display for probability variation 24 are changed when the display symbols are aligned with a predetermined symbol, they may be changed even when the other conditions are satisfied. The following conditions can be considered as conditions for improving the probability in that case.

(1) The probability may be improved when the variable display device 4 or the special variable display device 14 performs variable display a predetermined number of times after the power is turned on. In addition, the probability may be improved when the display result of the special variable display device 14 is a combination of probability improving symbols different from the big hit symbol or a combination of probability improving symbols same as a certain symbol of the big hit symbols. In addition, the probability may be improved when the reach state described above occurs. Further, the probability may be improved when the display result of the normally variable display device becomes the predetermined identification information. The predetermined identification information may be a predetermined display among the hit displays, a predetermined display other than the hit display, or all the displays normally hit by the variable display device 4. In addition, when the probability is improved when the special variable display device 14 is a combination of identification information that is a big hit, the probability may be improved together with the occurrence of the big hit.

(2) The probability is improved when the value of the random counter extracted when the hit ball is won in the ordinary variable winning ball device 8, the starting winning opening 12, and the starting passage openings 5a and 5b is a predetermined value. You may let me.

(3) The probability may be improved when one hit ball or a predetermined number of hit balls pass through a specific passing area. The specific passage area may be provided in the game area, may be provided in the special variable winning ball device 17, or may be in the normal variable winning ball device 8. It may be provided.

(4) The probability may be improved in the case where a combination of identification information that makes a hit does not occur within a predetermined period (elapse of a predetermined time or variable display of a predetermined number of times). The case where the combination of the identification information that makes a hit does not occur means that the combination of the identification information that makes a big hit of the special variable display device 14 does not occur and the combination of the identification information that makes a hit of the normal variable display device 4 does not occur. There are three possible cases, i.e., the case where no identification information is generated for both variable display devices.

(5) The probability is improved when the number of difference balls, which is the difference between the number of balls hit in the game area and the number of balls replenished to the gaming machine, or the rate of prize balls, reaches a predetermined value. You may let me.
The number of difference balls and the ball output rate may be from the time of opening the store or from a predetermined time.

When the above conditions (1) to (5) are satisfied, the special variable winning ball device 17 and the normal variable winning ball device 8 are opened instead of expanding the hit range when determining the hit or miss. The number of combinations of display results may be increased.

Next, as the condition for ending the probability improving state, the following may be set as the ending condition.

(1) It may be terminated when the display result of the special variable display device 14 or the ordinary variable display device 4 becomes the predetermined identification information. The predetermined identification information may be a predetermined display or a predetermined display other than the display of the hits. Further, it may be ended by the occurrence of the reach state described above.

(2) When the value of the random counter extracted when the hit ball is won in the ordinary variable winning ball device 8, the starting winning opening 12, or the starting passage openings 5a and 5b is a predetermined value, the operation is terminated. Good.

(3) The ball may be terminated when one hitting ball or a predetermined number of hitting balls pass through a specific passing area. The specific passage area may be one formed in the game area, one formed in the special variable winning ball device 17, or one formed in the normal variable winning ball device 8.

(4) After the start of the probability improvement state,
(A) When a predetermined time has elapsed, (b) When the variable display of the ordinary variable display device 4 or the special variable display device 14 is performed a predetermined number of times, (c) The passage of a predetermined time or the ordinary variable display device 4 or the special variable display device 14 The probability improving state may be terminated when the condition of whichever of the predetermined number of variable displays of the variable display device 14 is earlier is satisfied, or (d) when the normal variable display device 4 has been hit a predetermined number of times. .. In addition, the above (a) ~
In the case of (d), the probability improving state may be repeatedly and continuously controlled when a predetermined repeated and continuous condition is satisfied.

(5) For example, the ordinary variable winning ball device 8
When the number of winning balls does not reach the predetermined number, such as when the number of winning balls is 0 or less than a certain number during the opening of Good.

(6) The normal variable winning ball device 8 and the starting winning opening 12 store the winning number of hit balls or the starting passing opening 5
The process may be ended when the number of passing balls for starting the ball hitting the a and 5b is lost.

(7) The process may be terminated when the number of difference balls or the rate of balls output reaches a predetermined value. In addition, the number of difference balls and the winning rate may be from the time of opening the store, from a predetermined time, or even from the start of the probability improving state.

Whether or not the predetermined probability variation condition is satisfied may be determined by the hall management computer provided in the game hall, and the probability variation condition is changed and set in the hall management computer. You may make it possible to register.

In the present embodiment, as an example of the game machine, the ball game machine in which the player purchases a pachinko ball and plays a game with the pachinko ball is shown, but instead, a predetermined valuable value can be specified. It may be a game machine such as a ball game machine or a slot machine that can be played using a recording medium such as a card on which information is recorded. Further, the probability variation may be varied not only on the software but also on the display. In the above-mentioned embodiment, the backup power source is not provided, but a backup power source may be provided if necessary. Also, in the pachinko gaming machine of the above embodiment,
Although the locking device is provided, this locking device is not always necessary. Instead of providing a locking device, a so-called key switch that operates the setting switch itself with a lock may be used. Further, it is also possible to provide only a single variable display device without normally providing the variable display device.

Further, in this embodiment, the special variable display device 1
The display result of 4 is a combination of specific identification information and a big hit occurs, and when the big hit ends, the variable indicator for probability fluctuation is variably displayed and stopped. The condition of start / variable stop is, for example, that a pachinko ball has passed a predetermined passing area provided in the game area, that the number of shot balls or the number of driven balls has reached a predetermined number,
Alternatively, any condition may be used, such as the display result of the special variable display device 14 or the normal variable display device 4 becoming a predetermined display result.
