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

FIG. 6 is a flowchart of a main routine for explaining the operation of the control circuit of FIG. This main routine is executed, for example, once every 2 msec. First, in step S (hereinafter simply referred to as S) 1, a stack set process is performed, and in S2, it is determined whether or not a RAM error has occurred. This decision
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 or not the value is equal to a predetermined value. Immediately after the program runs away or immediately after power-on, the data stored in the RAM is indefinite, so the answer to the determination is NO and the control proceeds to S3. S3
In, initial data is written to the RAM. At this time, the value set by the probability setting switch 75 is read, and control is performed so that specific identification information is displayed on the ordinary variable display device 4 and the special variable display device 14 at a probability determined according to the read value thereafter. You. Thereafter, the control proceeds to S10. Since the initial data is written in S3, when this main routine is executed thereafter, the answer to the determination in S2 is YES, and the control directly proceeds to S4.

In S4, data output processing from the input / output port is performed, and a control signal is output to various circuits and devices shown in FIG. Next, proceeding to S5, it is determined 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, a case where 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 for a predetermined time (for example, 2.9 seconds), or when the special variable winning ball device 17 is opened once, the winning ball is detected. If no one is detected, it is determined that there is a 10 count error. The drum error is a case where the rotating drums 46a to 46c (see FIG. 2) stop in the middle of the rotation or become in a state where the rotation cannot be controlled. If there is no 10 count error and no drum error, S6
If there is a 10 count error or a drum error, the process goes to S9.

At S6, it is determined whether or not the number of resets is odd. The number of resets is determined by the reset signal input to the basic circuit 64 from the clock reset pulse generation circuit 66 (see FIG. 5).
4 means the number of resets, and each time it is reset, "0" is incremented by "1" to reach "7",
In this state, “1” is further added to “0”, and the count is incremented from “0” again. If the number of resets is 0 or even, the special symbol process is performed in S7. If the number of resets is odd, the normal symbol process is performed in S8 and then the process proceeds to S9.

At S9, a switch input process is performed.
Proceeding to S10, processing for updating the random counters of random 1, random 2, and random 4 is performed. The random 1 counter is a primary lottery counter for determining whether or not to make the display result at the time of stopping the special variable display device 14 a big hit, and the display result of the probability variation variable display 24. Is a counter for determining a symbol other than the probability variation symbol (missing symbol) when it is determined not to be a probability variation symbol (hit symbol). The random 2 counter is a random counter for a secondary lottery for determining whether or not the display result when the special variable display device 14 stops is a big hit, and the display of the variable display for probability variation 24. It is a lottery counter for determining 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. Have been.

The range of values that can be taken by the random 1 counter is 0 to 99, and the number of possible values differs between the normal case and the probability improvement case. Normally, the number of hits is four, and when the probability is improved, it is forty. That is, when the probability is improved, the probability of winning in the primary lottery for determining whether or not a big hit is 10 times the normal probability. On the other hand, the range of values that can be taken by the random 2 counter is 0 to 659, and the number of hits is determined by setting the probability setting switch to 1 to 3.
It depends on which of That is, control is performed such that the number of hits is 57 when the probability setting switch 75 is set to 1, 60 when set to 2, and 65 when set to 3. Is done.

Therefore, the jackpot probability on the software changes in six ways depending on whether the probability is normal or improved and the setting of the probability setting switch 75. Among them, the jackpot probability at normal time is as follows. Probability setting switch 7
When 5 is the setting 1, the probability per primary lottery is 4/100, and the probability per secondary lottery is 57/660.
Since the big hit is a hit only in both the primary lottery and the secondary lottery, in the case of the setting 1, the big hit probability is 4/100 × 57/660 ≒ 1 / 289.5. Similarly, in the case of setting 2, the probability per secondary lottery is 60 /
660, the jackpot probability is 4/100 × 60/6
60 = 1/275. In the case of setting 3, the probability per secondary lottery is 65/660, and the probability of big hit is 4/100.
× 65/660 ≒ 1 / 253.8.

If the display result of the variable display for variable probability 24 at the time of variable stop is a probability improvement symbol consisting of 3 or 7 crosses, the hit probability of the primary lottery is 4 as described above.
From / 100 to 40/100. Therefore, the big hit probability in the case of the settings 1 to 3 also becomes 10 times.

On the other hand, when performing the above-described random variation symbol lottery using the random 2 counter, the probability variation symbol for improving the probability of the winning symbol of the special variable display device 14 and the ordinary variable display device 4 appearing is changed. The probability of coming out is
The same probability is set for the probability variation symbol for the special variable display device 14 and the probability variation symbol for the normal variable display device 4, 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 a high probability state after a jackpot is 132/660 = 1/5 in setting 3, and 120 in setting 2.
/660=1/5.5, 110/660 = 1 / at setting 1
It becomes 6.

As described above, the special variable display device 14
The average probability that the combination of the symbols in which the display result of “” is established is as follows.

In the case of setting 3, 1 / ｛253.8 × (1-
1/5) + 25.38 × 1/5｝ ≒ 1/208 For setting 2, 1 / ｛275 × (1-1 / 5.5) +2
7.5 × 1 / 5.5｝ ≒ 1/230 For 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 falls within the range of ± 10% of the display probability 1 / 2227.56.

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

When the probability setting switch 75 is set to setting 3, the range of values that the random 4 counter can take is 0 to 44, for setting 2 is 0 to 47, and when setting 1 is 0 to 44. 53 is obtained. Normally, only one of the values in the range of the random 4 can be hit, but the display result when the variable display 24 for variable probability is stopped variably consists of a set of numbers other than 3 and 7. In the case of a probability improvement symbol, the hit probability is improved, and 10 of these values are hit. Therefore, at normal time, the probability that a symbol is displayed on the normally variable display device is 1/4 in the case of setting 3.
5, 1/48 for setting 2, 1/54 for setting 1
Thus, the lottery is performed with the setting 3 being the highest probability and the setting 1 being the lowest probability. When the probability is improved, the probability is increased by a factor of 10, respectively.

In the case of this embodiment, a special symbol,
Although the setting of the probability of the ordinary symbol and the symbol for the probability variation is adjusted by using the same probability setting switch 75, the probability may be adjusted separately for each of the special symbol, the ordinary symbol, and the symbol for the probability variation. Alternatively, it may be possible to adjust only the probability that the display result at the time of stopping the variable display for probability variation 24 becomes a probability variation symbol. See Figure 2 for this.
8 will be described later. Further, the probability may be adjusted for only one of the special symbol and the ordinary symbol. Also, the method of adjusting the jackpot probability on software is not limited to the method described above, and any method that can adjust the jackpot probability on software as a result in a predetermined range can be used. Good.

Then, the program proceeds to S11, in which it is determined whether or not the number of resets is "0", "4", "1, 2, 3, 5, 6, 7". Proceeds to S12, an output data table is selected, and the process proceeds to S15. 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 S14, the speaker 62 emits a sound effect described later with reference to FIG. If the number of resets is "1, 2, 3, 5, 6, 7", decorative LED and lamp control are performed in S13, and the process proceeds to S15. In accordance with S13, display of various lamps and decorative LEDs is controlled in a manner shown in FIG.

In S15, a storing process to the winning storage area is performed, and the process proceeds to S16, where random 1, random 2,
A process of updating the random 3 and random 5 count values is performed. The updating process in S16 uses the interval time (for example, 2 msec) of the reset pulse issued from the clock reset pulse generation circuit 66 to S1.
The control operation of S15 to S15 is performed, and the control operation is repeatedly performed using the reset waiting time after the control operation is performed. The random 3 counter is a random counter for determining a stop symbol when the special variable display device 14 comes off. The five random counter is a random counter for determining a stop symbol when the variable display device 4 comes off. Symbol because there sixteen for each of the three columns, the possible values of the random 3 counter may take 0~FFF in hexadecimal, that is, the value of 16 ^triplicate.
Further, for the random 5, three patterns can be displayed on each column of the ordinary variable display device 4, so that 3 ³ = 27
Values, that is, values from 0 to 26.

FIG. 7 is a flowchart showing a subroutine program of the ordinary symbol process process shown in S8. By S17, the normal symbol process flag is set to “0”,
It is determined whether or not "1-3", "5", "4, 6". The ordinary symbol process flag is a flag necessary for controlling the ordinary variable display device according to a predetermined order. The ordinary symbol process flag is set to "1" in S42 to be described later, incremented by "1" in S49, and added in S54. It is set to "5", set to "6" by S57, and set to "0" by S62. If the normal symbol process flag is set to "0", the process proceeds to S18, where the normal process shown in FIG. 9 described below 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. When the normal symbol process flag is set to "5", the process proceeds to S20, and FIG.
1 is performed. If the normal symbol process flag is set to "4" or "6", the process proceeds to S21, and the opening control shown in FIG. 12 is performed.

FIG. 8 is a flowchart showing a subroutine program of the special symbol process shown in S7. In S22, the value of the special symbol process flag is determined. The special symbol process flag is a flag necessary for controlling the pachinko gaming machine in a predetermined order, and is set to "1" in S70, described later, set to "2" in S76, and set to "3" in S75. ”, Set to“ 4 ”by S81, set to“ 4 ”by S87, set to“ 5 ”by S90, set to“ 6 ”by S93, set to“ 7 ”by S98, It is set to “9” in S104, set to “10” in S106, set to “11” in S108, and set in S113.
Is set to “12”, is set to “0” by S147, is set to “13” by S124, and S
It is set to "14" by 118, set to "16" by S134, and "1" is added by S140. If the special symbol process flag is set to "0", the process proceeds to S23, where the normal process shown in FIG. 13 is performed. When 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. When the special symbol process flag is set to “2”, the process proceeds to S25,
The big hit symbol setting process shown in FIG. 15 is performed. When the special symbol process flag is set to "3", the process proceeds to S26, and the lost symbol setting process shown in FIG. 16 is performed. When 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. If the special symbol process flag is set to "6 to 9", the process proceeds to S29, and each drum stop process shown in FIG. 20 is performed. S if the special symbol process flag is set to “10” or “11”
Proceeding to 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 opening process shown in FIG. 22 is performed. S if the special symbol process flag is set to “14” or “15”
Proceeding to 32, post-open processing shown in FIG. 23 is performed. If the special symbol process flag is set to "16 to 18", the process proceeds to S33, and a probability variation symbol stop process shown in FIG. 24 is performed.

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

At S148, switch port input processing is performed. By this processing, the switch input circuit 72
Detection signals from various detectors are input to the basic circuit 64 via (see FIG. 4). Next, a 10-count switch error check process is performed in S149, and a V-switch error check process is performed in S150. 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. If so, the subroutine program ends as it is. This S151 and S5
When it is determined that there is an error, an alarm flag is set and an alarm display and an alarm sound are generated (not shown).

If it is determined in step S151 that there is no error, the flow advances to step S152 to turn on the special symbol start switch.
Is determined. In the present embodiment, the special symbol start switch refers to a start winning prize ball detector 11 and a start winning prize hole 12 of the ordinary variable winning prize ball device (electric winning combination type starting winning opening) shown in FIG. There is a starting winning ball detector 13 for detecting a winning ball.
First, one of the starting winning ball detectors 11 and 13 is checked, and when the checking is completed, the other winning ball detector is checked. First, a state in which the start winning ball detector 11 provided in the normally variable winning ball device 8 is checked will be described.
If no pachinko ball has been won in the normal variable winning ball device 8, the detection signal from the starting winning ball detector 11 is not derived, so a negative determination is made in S152 and S1 is performed.
At 53, the corresponding ON counter, that is, the ON counter corresponding to the starting winning ball detector 11 is cleared, and S1 is executed.
Go to 59. The ON counter is a counter which is incremented by "1" when the switch input subroutine program is executed every 2 msec and the determination of YES is continuously made in S152. If a pachinko ball wins in the ordinary variable winning ball device 8 and is detected by the starting winning ball detector 11, a detection pulse having a predetermined pulse width is derived, and YES is determined in S152 by the number of times corresponding to the pulse width. A determination is made, and each time the ON counter is counted up. If the value of the ON counter reaches a predetermined value (for example, "3"), a determination of YES is made in S154, and a determination is made that a winning prize ball has been detected. On the other hand, if the start winning ball detector 11 erroneously detects due to noise, even if a detection signal is instantaneously derived and YES is determined in S152, the next execution of this switch input subroutine program is executed. At this time, since the detection pulse from the starting winning ball detector 11 has already fallen, the process proceeds to S153, where the ON counter is cleared, and the ON counter does not reach a predetermined value (for example, “3”). A determination of NO is made in S154, and the erroneous determination of the starting winning ball due to the noise can be prevented.

When the determination of YES is made 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 ball detector 11 of the electric drive start opening. If it is the start winning prize ball detector of the electric winning opening, the process proceeds to S156, and the number of ordinary electric winnings is incremented by "1", and the process proceeds to S157.

In S157, it is determined whether or not the number of stored special startups has reached the maximum (for example, 4). If not, the process proceeds to S158 because there is still room, and the number of stored special startups and the number of startups are determined. The number of winnings and the number of winnings are each added by "1", and the process proceeds to S159. On the other hand, if the special start storage number has already reached the maximum (for example, 4), it cannot be stored any more, so the determination of YES is made in S157, and the process proceeds to S159 without performing the addition process. Then S1
Proceeding to 59, it is determined whether or not all the special symbol start checks have been completed.
The process proceeds to 0, but if the process has not been completed yet, the process proceeds to S152, where a check is made for a special symbol start switch that has not been completed, that is, a start winning ball detector 13 (see FIG. 1). The check of the start winning ball detector 13 is performed in substantially the same manner as the check of the starting winning ball detector 11 of the ordinary variable winning ball device 8 described above.
The point is that the determination at 55 is NO and the process proceeds to S157 without performing the addition process at S156.

When all the special symbol start checks have been completed, the routine proceeds to S160, where the normal symbol start switch is checked thereafter. In the present embodiment, as the ordinary symbol start switch, the start passage openings 5a, 5
b, the starting passage ball detectors 6a and 6b (FIG. 1)
), One of the starting passing ball detectors is checked, and then the other starting passing ball detector is checked. First, the case where the starting passing ball detector 6a is checked will be described. If the pachinko ball has not been awarded in the starting passage 5a, the starting passage detector 6a is in the OFF state.
The corresponding ON counter, that is, the ON counter corresponding to the starting passage ball detector 6a is cleared, and S165
Proceed to. On the other hand, if the pachinko ball passes through the start passage opening 5a and is detected by the start passage ball detector 6a, a detection pulse having a predetermined pulse width is derived. Every time this switch input subroutine program is executed,
An ES determination is made. By this S160, YE continues
When the determination at S is made, the ON counter is counted up each time. When the counter value reaches a predetermined value (for example, “3”), the determination at S162 is YES. The processing of S161 and S162 is the same as that of S1 described above.
This is for preventing erroneous determination due to noise as in the processing of 53 and S154. Even if a detection signal is instantaneously derived from the starting passage ball detector due to noise, S162 is performed.
This is to prevent the erroneous determination that the pachinko ball has passed through the determination of NO.

If YES is determined in S162, the process proceeds to S163, in which it is determined whether or not the number of ordinary startup memories has reached a maximum (for example, 4). If not, there is still room. In S164, the normal start storage number and the start passage number are each incremented by "1", and the process proceeds to S164.
Proceed to 165. On the other hand, if the normal start storage number has already reached the maximum (for example, 4), it cannot be stored any more, so the process proceeds to S165 without adding. In S165,
It is determined whether or not all the ordinary symbol start checks have been completed. If the check has been completed, the subroutine program is terminated as it is. If not completed yet, the process returns to S160 again, and S160 to S16
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 passing starts is "0". The number of start passes is incremented by “1” in S164 and decremented by “1” in S168 described later. If the number of passing starts is "0", S16
The process proceeds to step S9, but if the starting passage number is not “0”, the process proceeds to step S16.
The process proceeds to S7, where the value of the random 4 counter (see S10) is stored in the corresponding area of the ordinary symbol prize storage area. The process returns to step S166 to repeat steps S166 to S168 until the number of passing passes becomes "0".
It should be noted that the number of start passes is a maximum of "2" even if all the ordinary symbol start switches are simultaneously determined to be ON, so that the process is completed if repeated twice at the maximum.

When the number of start passes has become zero, the process proceeds to S169, and it is determined whether or not the number of start winnings is "0". The start winning number is incremented by "1" at S158 and decremented by "1" at S171 described later. If the starting winning number is "0", the subroutine program is terminated as it is.
The process proceeds to S170, where the values of the random 1 counter and the random 2 counter (see S10) are stored in the corresponding area of the special symbol winning storage area, and after the starting winning number is decremented by "1" in S171, S169 is performed. , And the processing of S169 to S171 is repeated until the starting winning number becomes “0”. The number of repetitions in this case is also a maximum of two for the same reason as described above.

Next, a subroutine program of the normal processing shown in S18 will be described with reference to FIG. S34
Thus, the data for turning off the solenoid 10 of the ordinary electric hand is set, and based on this data, the solenoid 10 of the ordinary electric hand is controlled to be turned off, and the normally variable winning prize ball device 8 is set.
Of the movable wing piece 9 is closed. Next, S35
It is determined whether or not there is an ordinary symbol prize storage. If there is no prize memory in the ordinary symbol prize storage area (see S167 in FIG. 26), the subroutine program is terminated as it is. Proceeds to S36, and a process of subtracting "1" from the normal start storage number (see S158 in FIG. 25) is performed. Next, the process proceeds to S37, in which it is determined whether or not the value of the random number 4 stored in the area 1 of the ordinary symbol winning storage area (see S167) is a hit value. The normal symbol prize 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 start storage, and the value of the random 4 counter stored in the area 1 is a hit. Is determined by this S37. At the time of the judgment, it is usually random 4
Only one value out of the range of values that can be taken by the counter 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 in S144 and S145 described later, the random Any of the ten values in the range of values that the four counters can take is determined to be a big hit. As a result, at the time of the probability improvement, the probability of a big hit is improved ten times compared to the normal case. S3
When it is determined that the big hit is determined by 7, the process proceeds to S38, and the left symbol = the middle symbol = the 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
By 38, the normal variable display device 4 is stopped and controlled so as to have predetermined identification information (for example, a certain symbol among 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, a symbol is set according to the count value of the random 5 counter, and the process proceeds to S40, where S3 is executed.
It is determined whether or not the symbol set in step 9 is left = middle = right. If not, the process proceeds to S42. On the other hand, if left = middle = right happens to happen, the symbol when the normal variable display device 4 is stopped as it is will be a combination of symbols as it is when it is stopped. Only the symbol is incremented by "1" and the symbol is forcibly shifted so that it is not crossed.

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

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

First, in S49, the display symbol is set to the stop symbol, and in S50, the normal symbol process flag is incremented by "1", and the flow advances to S51. Thereby, the left symbol stops first. In S51, it is determined whether or not the ordinary symbol process flag is "4". At this stage, since the normal symbol process flag should be "2", the determination of NO 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.
The time is about 4 seconds. In the next execution of the normal symbol process, the symbol stop process in S19 is performed because the normal symbol process flag is "2", and
If the symbol stop waiting time set in S52 ends, the determination of YES is made in S48, and the processes of S49 and S50 are performed. At this stage, the middle symbol stops and the ordinary symbol process flag becomes "3". Therefore, the determination of NO is made in S51, and the process proceeds to S52. Further, at the next execution of the normal symbol process processing, since the normal symbol process flag is "3", each symbol stop process of S19 is executed again, and the rotation process of the ordinary symbol LED in S47 is continuously performed. S48, S49, S50
Is performed. As a result, the right symbol stops, and the ordinary symbol process flag becomes "4". Therefore, the determination of YES is made in S51, the process proceeds to S53, and the process timer A is set to the waiting time. The departure waiting time is about one second. Next, in S54, it is determined whether or not the left symbol = the middle symbol = the right symbol. If the determination is NO, the subroutine program is terminated. On the other hand, when the left symbol = the middle symbol = the right symbol, S5
Go to 5 to update the normal symbol process flag to “5”
The opening wait time (about 0.5 seconds) is set in the process timer A.

When the determination of NO is made in S54, the ordinary symbol process flag is "4".
21 is executed. FIG. 12 shows a subroutine program of the processing during opening in S21. The normal symbol process flag is set to “4” by S59.
Is determined, and since it is “4”, S6
The process proceeds to step S2, where it is determined whether or not the process timer A set in step S53 has expired. If not, the subroutine program ends. Even in this state, since the ordinary symbol process flag remains "4", a determination of YES is made in S59 also in the next execution of the ordinary symbol process processing, and whether or not the process timer A has expired in S62. A decision is made. Then, the process loops through the loop of S59 and S62 until the process is completed, and when the process is completed, the process proceeds to S63, in which the normal symbol process flag is updated to “0”. As a result, in the next execution of the ordinary symbol processing, the processing shifts to the ordinary processing shown in S18.

On the other hand, if YES is determined in S54, the ordinary symbol process flag has been updated to "5", so that when the next ordinary symbol process process is executed, the normal symbol process process is executed before opening shown in S20. The processing program is executed. The pre-opening subroutine program
This is shown in FIG. In S56, it is determined whether or not the process timer A set in S55 has expired, and if not, the subroutine program ends. Then, when the process timer A has expired, the process proceeds to S57, where the number of ordinary electric winning combinations is cleared, and the process proceeds to S58. The winning number of the ordinary electric winnings is a value added by “1” in S156, and the winning balls that have won the ordinary variable winning ball device 8 are counted, and the ordinary variable winning ball device 8 is won by one opening. 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 normal timer opening time (for example, 5.9 seconds) is set in the process timer A.
Is set.

In the next execution of the normal symbol process, the open symbol processing program in S21 is executed because the normal symbol process flag has been updated to "6" in S58. As a result, the process proceeds to S59, where it is determined whether or not the ordinary symbol process flag is "4". Since the ordinary symbol process flag is "6", the process proceeds to S60, and the solenoid 10 of the ordinary electric hand is operated. 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 of the normal electric-power in accordance with S4, and the solenoid 10 of the normal electric-power is used.
Is excited, and the movable wing piece 9 of the ordinary variable winning ball device 8 is opened for a maximum of 5.9 seconds. Next, the process proceeds to S61, in which it is determined whether or not the number of ordinary electric prize winnings has reached the maximum (six). If not, the process proceeds to S62, but if it has, the process proceeds to S63, The normal symbol process flag is updated to “0”. As a result, when the next ordinary symbol process is executed, the ordinary process of S18 is executed.
As a result, in S34, the solenoid 10 of the normal electric
The data for the FF is set, and the normal variable prize ball device 8 is switched to the second closed state. 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 at the time of stopping the ordinary variable display device becomes predetermined identification information is configured. I have.

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

Next, in S67, it is determined whether or not the result of the primary lottery is a hit. If it is determined that the result is a hit, a process of setting the primary lottery flag to "hit" is performed in S69, If it is determined that it is off, S68
Is performed to set the primary lottery flag to "out". Next, in S70, the special symbol process flag is updated to "1", and the subroutine program ends. In the next execution of the special symbol process, 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. At S71, it is determined whether or not the primary lottery flag is set to "hit", and it is not set to "hit". S7 in case
Proceed to S5, but if it is set to "hit", S7
Proceeding to 2, the value of the random 2 counter stored in area 1 of the special symbol winning storage area is determined, and in S73, it is determined whether or not the result of the secondary lottery determination is a win. If it is determined that it is not, the process of setting the primary lottery flag to "miss" in S74 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 setting of the probability setting switch 75 is 1 among the possible values of the random 2 counter in the range of 0 to 659.
In the case of setting 2, the number is set to 60, and in the case of setting 3, the number is set to 65.

Then, the program proceeds to S77, in which the special start storage number (FIG. 2)
5S158) is subtracted by "1".
The process proceeds to step S8, in which the data stored in the special symbol winning storage area is shifted one by one, and the subroutine program ends. The processing for shifting the special symbol winning storage area is the same as the processing in S42 described above. In the next execution of the special symbol process processing, the special symbol process flag is set to “3”, so that the process of the missing symbol set in S26 is performed.

On the other hand, if it is determined in S73 that the second lottery result has been hit, the flow proceeds to S76, in which the big hit symbol number is set based on the remainder of the current random 2 counter divided by 18, and the special symbol is set. The process flag is set to "2" and the process proceeds to S76. As described above, the remainder value obtained by dividing the random 2 counter by 18 is 0 to 17
There are eight different values, corresponding to eighteen combinations of big hit symbols.

As a result of the processing in S76, in the next execution of the special symbol process processing, the special symbol process flag is set to "2", so that the big hit symbol set processing in S25 is executed. The big hit symbol set subroutine program is shown in FIG. S
With 79, a big hit symbol is set according to the big hit symbol number. The big hit symbol numbers correspond to the 18 combinations of big hit symbols as described above, and a stop symbol number that becomes a big hit according to the value is set. The stop symbol number is the number shown in the leftmost column shown in FIG. Next, in S80, the hitting row LE
The D data is set, and a process of setting the big hit flag to “reach” or “big hit” is performed. The hit column LED data set in S80 is S4
Is output to the hit row display LED 16 (see FIG. 1), and the display of the hit row display LEDs 16 located at both ends of the hit row where a specific combination of identification information is aligned is controlled. Next, S8
With 1, the special symbol process flag is set to "4". As a result, when the next special symbol process process is executed, the process of the sub CPU command set shown in S27 is performed. A subroutine program of this sub CPU command set is shown in FIG.

At S88 in FIG. 17, a command is set to the sub CPU. This command is
As shown in FIG. 9, the data is temporarily stored in the sub CPU command area on the basic circuit 64 side. As shown in FIG. 19, the specific contents of the stored data are, as shown in FIG. 19, a header indicating the start of the output of the command, a command for specifying whether the rotating drums 46a to 46c are in normal rotation or an abnormal recovery, a left stop. A symbol, a middle stop symbol, a right stop symbol, a big hit flag, and a drum control flag. Note that the abnormality recovery means that when an abnormality occurs in the special variable display device 14, the person in charge of the game arcade repairs the abnormality and rotates the rotating drum after the restoration. The drum control flag includes S89 in FIG.
, The number of winning storages in the special symbol winning storage area is set. When the winning storage number is equal to or more than "1", a shortening mode is set in which the basic time from when the special variable display device is variably started to when the control shifts to the stop control is shortened. In addition,
As a condition for setting the basic time to the shortened mode, the condition that the variable display device is in the probability improvement state may be added to the condition. That is, the fluctuation time may be reduced only when the probability is improved. Next, in S90, the special symbol process flag is set to “5”. As a result, in the next execution of the special symbol process, the sub CPU command output process shown in S28 is performed. This sub C
The PU command output subroutine program is shown in FIG.

At S91, the sub CPU command output is set. This output is output from the data stored in the sub CPU command areas 0 to 6 on the basic circuit 64 side by one each time S90 is executed. Output to the command input area. Since this S90 is executed once every 4 msec, it takes 28 msec to transmit all seven types of data stored in the storage areas 0 to 6.
Time is needed. The sub CPU checks the input of the command data on the basic circuit side for 2 msec.
It is executed once every c. If the input command data is 1F, it is determined that the command has started, and the next and subsequent command data are stored as valid data in the corresponding sub CPU command input area sequentially every 4 msec. Then, by S92 of FIG.
It is determined whether or not the command output has been completed. If all the command outputs have been completed, the process proceeds to S93, where the special symbol process flag is set to “6”, and the process timer B is set to the basic left stop time. Then, processing for setting the drum reference rotation speed is performed, and the subroutine program ends. The left stop basic time set in the process timer B is a time from when the special variable display device 14 is variably started to when the process shifts to the stop control of the left symbol. It is about 7 seconds, and about 6 seconds in the case of the standard mode which is not the shortening mode. The drum reference rotation speed is used to determine the rotation speed of each of the rotary drums 46a to 46c of the special variable display device 14, and is, for example, 12 rotations in the standard mode and, for example, in the shortening mode. 4 rotations. In 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 is out of the secondary lottery, the special symbol process flag is set to "3" in S75, so that the next special symbol process process is executed. Is set in the off symbol shown in S26. FIG. 16 shows a subroutine program for the set of the lost symbols.

At S82, an off symbol is set based on the value of the random 3 counter. At this point, the big hit flag is cleared. In S83, it is determined whether or not the set left symbol and right symbol are the same symbol. If they are not equal, the process proceeds to S87, but if they are equal, S84
As a result, the hit column LED data is set,
The big hit flag is set to "reach". Next, S85
It is determined whether or not the left symbol = the middle symbol = the right symbol. 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 step S86, a process is performed in which only the middle symbol is added and shifted by "1". This is a process performed when the set symbols happen to be equal between the left, middle, and right despite the fact that the symbols are deviated in S73 as a result of the primary lottery and the secondary lottery. Forcibly shift the middle symbol to the missing symbol. Next, in S87, the special symbol process flag is set to "4".

In the next special symbol 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 a subroutine program of each drum stop control is shown in FIG. ing. S94
Thus, a motor step check process is performed. The motor step check is a process of adding "1" to the drum rotation counter each time the drum sensors 51a, 51b, and 51c shown in FIG. 2 are turned on. Next, the process proceeds to S95, and it is determined whether or not the process timer B has expired. This process timer B is
S98, S102, S102 are timers necessary for measuring various display control times of the special variable display device 14.
104, S113, S106, S108, S113, S
Each time is set by 118. If it is determined that the process timer B has expired, the flow advances to S96 to set a drum stop sound. The set drum stop sound is output to the speaker 62 according to S4,
A drum stop sound is output from the speaker 62. Next, S9
The process proceeds to S7, where it is determined whether or not the special symbol process flag is set to "6". At this stage, since the special symbol process flag is set to "6", the process proceeds to S98, and the special symbol process flag is set to "7". And a process of setting the right drum stop time in the process timer B is performed. The right drum stop time is such that each of the rotating drums 46a to 46c is left,
The stop delay time required for shifting the time to stop in the order of right and middle is about 0.6 seconds.

Even when the special symbol process flag is set to "7" in S98, each drum stop process of S29 is performed at the time of executing the next special symbol process process as shown in FIG. In this case, a determination of NO is made in S97, a determination of YES is made in S99, and a determination is made as to whether or not there is a drum error in S100. The drum error is, as described above, when the rotating drum is stopped during rotation or when rotation control becomes impossible, specifically, the reference rotation number set in S93 and the drum rotation number counted in S94. Do not match. In this case, a drum error is set in S101, an alarm is issued, and control is performed at the time of a predetermined abnormality. Next, if no drum error has occurred, the process proceeds to S102, in which a special symbol process flag is set to "8", and a process timer B is set to a medium drum stop time (about 0.6 seconds). It is.
Next, in S103, it is determined whether or not the big hit flag is set to “reach”. The “reach” is set in S80 and S84, and is a display state in which the possibility of a big hit state remaining when the left rotating drum 46a and the right rotating drum 46c are stopped remains. Means the case. If it is not set to "reach", the subroutine program ends. Also in this case, since the special symbol process flag is set to "8", each drum stop control of S29 is performed again. On the other hand, when 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 in the process timer B. The reach operation time is about 3 to 5 seconds. Only after the reach operation time set in the process timer B has expired, as will be described later, the special symbol process flag is set to "10" or "11", the respective drum stop control ends, and the rotation of all drums is stopped. Will be suspended. Therefore, when the big hit flag is set to "reach", the center rotating drum continues to rotate for about 3 to 5 seconds even after the left and right rotating drums stop. The reach operation time is 16 times depending on the type of the stop symbol because there are 16 types of the symbol of the center rotating drum.

When the next special symbol process is executed and it is determined in S95 that the process timer B has expired, the processing of S96, S97, S99 and S105 is performed, and the big hit flag is set to "big hit". If not, the flow advances to S106 to perform a process of setting the special symbol process flag to "10", set a departure waiting time (about 1 second) in the process timer B, and ends the subroutine program. When the next special symbol process is executed, the special symbol process flag is set to “10”.
, The hit check process shown in S30 is performed.

On the other hand, if it is determined in S105 that the big hit flag has been set to "big hit", then in S10
Then, the process proceeds to step 7 in which the hit range in the hit determination of the random 1 counter and the random 4 counter is set to a normal value. That is, in the present embodiment, the probability improvement state ends when a big hit occurs in the special variable display device. As a result, when the hit is determined in S37, only one of the possible values of the random 4 counter is determined to be a big hit.
Further, in the case of judging the hit or miss in S67, only four values in the range of possible values of the random 1 counter are judged as hits. Next, 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 is terminated. If the special symbol process flag is set to "10" or "11", the hit check process shown in S30 is performed when the next special symbol process process is executed.

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

FIG. 22 is a flowchart of the opening process performed in S31 of FIG. At S114, the jackpot 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. At S115, a V switch and 10 count switch check processing is performed. This processing is performed in the specific winning area 21.
This is a process for determining whether or not there is a winning ball in the winning area 18 (see FIG. 1), and whether or not there is a winning ball in the winning area 18. The details will be described later with reference to FIG. Subsequently, in S116, it is determined whether or not the number of pachinko balls that have won the winning area 18 has reached a predetermined maximum number as a result of the processing of S115. If the winning number is not the maximum, the process proceeds to S117, where the special variable winning ball device 17
Maximum time to keep in the state of (for example, 30 seconds)
It is determined whether or not the process timer B for determining whether or not has elapsed has expired. Process timer B
If has not been completed yet, there is room for both the winning number and the opening time, so this subroutine ends as it is. If it is determined in S116 that the winning number is the maximum, and if it is determined in S117 that the process timer B has expired, the process proceeds to S118, and it is necessary to change the special variable winning ball device 17 to the second state. , 15 is set to the special symbol process flag, and a value corresponding to the V reception time is set to the process timer B. V
The reception time means that even after the special variable prize ball device 17 is set in the second state, there may be a pachinko ball that wins later in the specific prize area 21.
This is the time for which the winning of the pachinko ball into 1 is valid, for example, about 2 seconds. After S118, this subroutine ends.

FIG. 23 is a flowchart showing a subroutine program of the post-release processing shown in S32.

In S119, output data for turning off the solenoid is set, and the set data is output in accordance with S4, the excitation of the solenoid 20 is released, and the variable prize ball device 17 is closed to be disadvantageous for the player. To the second state. Next, proceeding to S120, a V switch (specific winning ball detector 22) and 10 count switch check processing are performed, and proceeding to S121, it is determined whether or not the process timer B has expired. Said S
FIG. 27 shows the specific contents of the process 120.

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, for example, by the basic circuit 64
(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 that the switch is ON a predetermined number of times (for example, three times) continuously, the V switch is turned ON. It is performed by judging that there is. By doing so, even if the signal supplied to the basic circuit 64 temporarily becomes a value indicating ON due to noise or the like, in such a case, the signal is turned OFF again in the next check. This is because, because of returning to the value, the determination as to whether or not the V switch is ON is not erroneously made due to noise. 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, where the winning number counter is incremented by 1, and S1 is performed.
Proceed to 74.

In S174, it is determined whether or not the number of times the special variable winning ball device 17 has been opened is maximum (for example, 16 times). When the number of times of release is the maximum, there is no need to continuously open, and winning in the V switch is invalidated. That is, if the result of the determination in S174 is that the number of times of release is the maximum, the control proceeds directly to S177. If the number of times of release is not the maximum yet, it is necessary to continue to open the special variable winning ball device 17 continuously. Therefore, it is first determined in S175 whether or not the V winning flag has been set. If the V winning flag has already been set, the process directly proceeds to S177, but if it has not been 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 the V winning is set. The data is set, and the process proceeds to S177. In S177, it is determined whether or not the timing of the 10 count switch is ON. This judgment also turns on the V switch
Is performed in the same manner as the timing (S172).
If the 10-count switch is not ON, this subroutine ends directly, but if it is ON, S178
The process is terminated after adding 1 to the winning number.

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. When the reception time has expired, the routine proceeds to S122, where it is determined whether or not the V winning flag has been set. The V winning flag is set in S176 described later, and the pachinko ball is placed in the specific winning area 21 (FIG. 1) during the period from the opening of the variable winning ball device to the end of the V reception time after the closing. ), A V winning flag is set.

If the V winning flag is set, the flow proceeds to S123, and it is determined whether or not the number of times of release is the maximum. Is updated to "13", the release time is set in the process timer B, and after the release counter is incremented by "1", the process proceeds to S135. On the other hand, if the release count has reached the maximum or if the V winning flag has not been set, the flow proceeds to S125, the release count counter is cleared, and the big hit information is set to OFF output.
A process of clearing the next lottery flag is performed. That is,
If the V prize flag is not set, the repetition continuation control for repeatedly continuing the variable prize ball device to the first state is not performed, and even if the V prize flag is set. However, if the number of times of release has already reached the maximum, the repetition continuation control is not performed any more, so the process in S125 is performed. Next, proceeding to S126, the current count value of the random 2 counter is determined, and in S127, the count value is changed to a high probability state in which the display result when the special variable display device 14 is stopped improves the probability of becoming a symbol. A determination is made as to whether the value is to be started. If the determination is YES, the process proceeds to S128, and the variable display for probability variation 2
A process of setting both the left and right of the stop symbol of No. 4 (see FIG. 1) to either 3 or 7 is performed, and S135 is performed.
Proceed to. On the other hand, as a result of the determination in S126, whether the count value of the random 2 counter is a value for starting the high probability state that improves the probability that the display result when the ordinary variable display device 4 (see FIG. 1) stops is a hit. It is determined whether or not the symbol is 0, 1, and both the left and right symbols of the stop symbol of the variable display for probability variation 24 are determined to be 0, 1, or S.
A process for setting any one of 2, 4, 5, 6, 8, and 9 is performed, and the process proceeds to S134. That is, when the display result at the time of stopping the variable display for probability change 24 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 for probability change 24 is stopped is “0”.
0 "," 11 "," 22 "," 44 "," 55 "," 6 "
If it is any of "6", "88", and "99", the variable display device 4 is normally controlled so that a big hit occurs with a high probability.

Next, if the result of determination in S126 is neither the special symbol high probability start value nor the normal symbol high probability start value, in S131, the variable display for probability variation is displayed according to the current random 1 counter count value. 24 stop symbols are set. Since the possible value of the random 1 counter is 0 to 99, the variable display 2 for probability variation is used.
This corresponds to the total number of stop symbol combinations of 4.
Then, as a result, if the left symbol and the right symbol happen to be equal to each other, YES is determined in S132, and the right symbol is forcibly shifted by “1” in S133, and the left symbol and the right symbol match. Not controlled. Next, in S134, the process of clearing the probability variation symbol LED timer, setting the left stop basic time in the process timer B, and updating the special symbol process flag to "16" is performed. This probability variation symbol LED timer is for measuring the time required for sequentially performing variable display control of the probability variation symbol LED, and is temporarily performed before the probability variation symbol LED starts rotating display in S138 described later. Cleared. The basic left stop time set in the process timer B is, for example, about 2 seconds. When the basic stop time elapses, the process shifts to the stop control of the left probability variation symbol LED on the probability variation variable display. Next, the process proceeds to S135, in which 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. Is performed. On the other hand, the fact that no pachinko ball wins while the variable winning ball device is being opened means that the 10-count switch for detecting the winning pachinko ball in the variable winning ball device may be faulty or incorrect. Therefore, in such a case, the process proceeds to S136,
S137 after the count error setting process is performed.
Proceed to.

Since the special symbol process flag is set to "16" in S134, the subroutine program of the probability variation symbol stop process shown in S33 is executed at the time of executing the next program. The subroutine program of this probability variation symbol stop processing is shown in FIG. 24. First, at S138, the probability variation symbol LED
Is rotated to variably display the variable display for probability variation 24 (see FIG. 1). Next, the process proceeds to S139, and it is determined whether or not the process timer B has expired. In the process timer B, the left stop basic time is set according to S134, and when the set left stop basic time has ended, the process proceeds to S140, and the display symbol displayed by the probability variation symbol LED is changed to the above-mentioned S128. Alternatively, the stop symbol set in S130 or S131 is set to the stop symbol, the stop symbol is stopped and displayed, and the special symbol process flag is advanced by "1". Next, the routine proceeds to S141, where 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 symbol timer waiting time is set in the process timer B. The symbol stop waiting time is a waiting time for stopping the right symbol after a predetermined time has elapsed after the left symbol has stopped, and is, for example, about 0.5 seconds.

At the time of execution of the next and subsequent programs, S
In 139, when the symbol stop waiting time set in the process timer B has expired, the process proceeds to S140. As a result, the right symbol is stopped and the special symbol process flag is advanced by "1", so that the special symbol process flag is set to "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, the process proceeds to S23 when the next program is executed. On the other hand, if the left symbol matches the right symbol, the process proceeds to S144, and it is determined whether 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 a process of changing the range of one random counter to the value at the time of the high probability is performed. As a result, the probability that the display result when the special variable display device is stopped and hits the symbol is improved by 10 times. On the other hand, when the left symbol is other than “3” and other than “7”, that is, 0,
If it is one of 1, 2, 4, 5, 6, 8, and 9, the process proceeds to S145, and a process of changing the range of the hit of the four random counters to the value at the time of the high probability is performed. As a result, the probability that the display result when the ordinary variable display device 4 (see FIG. 1) is stopped and hits a symbol is improved by a factor of ten. Although not shown in the processing of S145 or S146, it is configured to notify the player from the speaker 62 that the probability has improved by setting the hit sound data (sound effect J in FIG. 28). Next, the process proceeds to S147,
The special symbol process flag is updated to “0”. S12
6 to S130 and S143 to S146, a probability changing unit that changes the probability that the display result of the variable display unit becomes the specific identification information when the display result of the display unit becomes the predetermined identification information is configured. ing.

FIG. 28 is a table showing display modes of various display devices which are display-controlled in accordance with various game states, and types of sound effects emitted from speakers.

The leftmost column in FIG. 28 shows the operation state of the pachinko game machine. To describe in order from the top, when the power is turned on, when the pachinko ball passes through the starting opening, that is, the starting passing opening 5a, When the pachinko ball passes through 5b, the normal symbol, ie, after the normal variable display device 4 is stopped (other than the hit), before the opening of the ordinary electric hand, ie, the ordinary variable winning prize ball device 8, when the ordinary electric hand is opened, the pachinko ball is released. At the time of starting opening prize, ie, a pachinko ball normally variable winning prize ball device 8 or starting winning prize opening 12
At the time of winning a prize, at the time of reaching, after the special symbol, that is, the special variable display device 14 is stopped (other than the big hit), before the opening of the variable winning sphere device 17 in the big hit state, the pachinko ball to the specific winning opening 21 in the big hit state. Before winning, after winning a pachinko ball in the special 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)

This means that the blinking is controlled at the timing of the N state. (C) is ON for 512 ms and then 15
This means that the blinking control is performed at the timing of being turned off for 36 ms. (D) means that blinking control is performed with 1024 ms as one cycle. (E) is 51
This means that blinking control is performed at a timing when the state becomes ON for 2 ms and then becomes OFF for 512 ms.
(F) is OFF for 768 ms and then 256
This means that the blinking is controlled at the timing of turning ON for ms. (F ') means that the blinking control is performed at the timing when it is first turned on for 256 ms and then turned off for 768 ms.

The phrase "when the probability is improved" in the row of the rail decoration lamps 41 means when the probability that the stop symbol is hit by the above S145 or S146 is improved. "At the time of probability improvement" in the row of sound effects of the speaker 62
Has the same meaning. Note that the sound effect J is generated only for a certain period when the probability is improved, and the blinking of the rail decoration lamp 41 is performed throughout the period of the probability improved state.

The number of difference balls and the payout rate may be from the opening of the store or from a predetermined time.

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

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

(1) The process may be terminated when the display result of the special variable display device 14 or the normal variable display device 4 becomes predetermined identification information. The predetermined identification information may be a predetermined display or a predetermined display other than the win display among the win displays. Alternatively, the process may be terminated by the occurrence of the above-described reach state.

(2) The process is terminated when the value of the random counter extracted when a ball is hit in the ordinary variable winning ball device 8, the starting winning opening 12 or the starting passing openings 5a, 5b is a predetermined value. Is also good.

(3) The process may be terminated when one or a predetermined number of hit balls have passed through a specific passing area. The specific passage area may be one formed in the game area, one formed in the special variable prize ball device 17, one formed in the normal variable prize ball device 8, or the like.

(4) After the start of the probability improvement state,
(A) When a predetermined time has elapsed, (b) When variable display of the ordinary variable display device 4 or the special variable display device 14 has been performed a predetermined number of times, (c) When a predetermined time has elapsed or when the normal variable display device 4 or the special The probability improvement state may be terminated when the earlier condition of the variable number of variable displays of the variable display device 14 is satisfied, or (d) when the normal variable display device 4 hits the predetermined number of times. . In addition, the said (a)-
In the case of (d), the probability improvement state may be repeatedly and continuously controlled when a predetermined repetition continuation condition is satisfied.

(5) For example, the normal 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 during the opening of the game is 0 or a certain number or less, or when the hit ball does not pass through a specific passing area, Is also good.

(6) The storage of the winning number of hit balls to the ordinary variable winning ball device 8 and the starting winning opening 12 or the starting passing opening 5
The process may be terminated when there is no longer any storage of the number of hit balls that have been passed through to a and 5b.

(7) The processing may be terminated when the difference ball number or the payout rate reaches a predetermined value. Note that the difference ball count and the payout rate may be those at the time of opening the store, may be those at a predetermined time, and may be those at the start of the probability improvement state.

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