Then, the sub-basic circuit 111 supplies a drive signal to the drum lamp 96 via the drum lamp circuit 119, a drive signal to the drum motor 99 via the drum motor circuit 120, and the drive signal is incorporated in the drum motor 99. An input signal is sent from the drum sensor 108 to the sub basic circuit 111 and the basic circuit 110 via the sensor input circuit 121.
The devices and circuits other than the drum lamp 96 described above are supplied with electric power having various voltages from the power supply circuit 122, and the drum lamp 96 is supplied with the power 12 for the drum lamp.
Electric power having a predetermined voltage is supplied from 3.

An example of a specific operation of the game control circuit described above will be described with reference to the time charts and explanatory diagrams shown in FIGS. 9 to 16. First, FIGS. 9 and 10 and FIG.
With reference to FIG. 2, the operation of the variable display when the variable display device 40 is in the off display will be described. FIG. 9 is a list of random numbers used for missed hits, and FIG.
It is explanatory drawing explaining the selection method of the winning symbol determined when the hitting ball has won the starting winning opening 4, and FIG. 12 is detachment of the variable display device 40 based on the winning of the hitting ball to the starting winning opening 4. It is a time chart which shows a variable display operation. In FIG. 12, when a ball hits the starting winning opening 4 and the starting winning ball detector 5 is turned on and the starting signal S1 is derived, one value is extracted from random 1 at the rising of the starting signal S1. Stored. Random 1 is, as shown in FIG. 9, a random number for determining whether or not it is a winning symbol, and 254 numerical values of “0 to 253” are fluctuating every moment after the power is turned on. Further, after deriving the start signal S1, 0.1
The value of random 1 stored when 28 seconds or 0.130 seconds has elapsed is read out, and after the start signal S1 is derived, 0.
One value is extracted from Random 3 when the read value of Random 1 does not hit after 132 seconds or 0.134 seconds has elapsed. This random 3 is, as shown in FIG.
Numerical values of 9261 kinds of "0 to 9260" change every moment, and the symbol corresponding to the extracted value is displayed at a predetermined position which is visible to the player. .

Therefore, when the numerical value extracted from the random 1 is other than "8", as shown in FIG. 10, it is judged not to be a big hit (the big hit in this case is synonymous with the specific game state) but to be out. The symbols corresponding to the values randomly extracted as described above are displayed at a predetermined position which is visible to the player. However, if the extracted value happens to coincide with the winning symbol (including the big hit and the medium hit), 1 is added to the random 3 data and the symbol is displayed as a deviating symbol.

As described above, at the time of deriving the start signal S1, it is determined whether or not the combination of symbols displayed on the variable display device 40 is a hit, and the symbol displayed at the time of stop is also determined. (In this embodiment, 0.204 seconds or 0.206 seconds after the start signal S1 is derived)
After a lapse of seconds), first, the left rotary drum 71a (hereinafter, referred to as a pattern 71a) starts to change, and a right time rotary drum 71c (hereinafter referred to as a pattern 71c) after a slight time interval (0.002 seconds). The central rotating drum 71b (hereinafter, referred to as the symbol 71b) starts to change in sequence. In the variable display of the pattern 71a, the basic time (6.
300 seconds), it will change at a predetermined fluctuation speed,
When the basic time elapses, it is stopped when the variation time for one symbol elapses. Similarly, in the variable display of the pattern 71c, during the same basic time as above (6.300 seconds), the predetermined fluctuation speed is set and fluctuates, and when the basic time elapses, the fluctuation time for 6 symbols elapses. When stopped.

On the other hand, in the variable display of the design 71b,
When the stop symbol on the hit line displayed on the symbols 71a, 71c that have already stopped is not the hit symbol (when not in the reach state) and when it is the hit symbol (when in the reach state)
And are variably displayed in different modes. Therefore, first, the fluctuation display when not in the reach state will be described. During the same basic time as above (6.300 seconds), the fluctuation is set to a predetermined fluctuation speed, and when the basic time elapses, fluctuations of 11 symbols will occur. It will be stopped when time passes. On the other hand, in the variable display in the reach state, during the same basic time (7.260 seconds) as the time until the symbol 71c stops, the predetermined fluctuation speed is set and fluctuates, and when the basic time elapses, After stopping for a short time (0.200 seconds),
42-62 patterns fluctuate at a slightly slower fluctuation speed,
It is stopped when the variation time of 2 to 22 symbols elapses at a slower variation speed. The fluctuation speed for these 64-84 symbols is set to a slightly slower fluctuation speed.

Next, FIGS. 9, 10 and 13 to 15
The operation of the variable display when the variable display device 40 performs the hit display will be described with reference to FIG. 13 to 15
FIG. 13 is a time chart showing the hit variable display operation of the variable display device 40 based on the winning of a ball hitting the starting winning opening 4. In FIG. 13, the values of random 2 to be described later are “6” and “1”.
This is a variable display operation in cases other than “8” and “38”.
Shows a variable display operation when the value of random 2 is “6”, and FIG. 15 shows a variable display operation when the value of random 2 is “18” “38”. Then, FIG. 13 shows a case of a so-called single reach state in which the reach state is established on any one of the hit lines, and FIGS.
The case is a so-called double reach state in which the reach state is established on any two hit lines.

First, in FIG. 13, when the hitting ball passes through the starting winning opening 4 and the starting winning prize detector 5 is turned on and the starting signal S2 is derived, the same as when the starting signal S1 is derived. At the rising of the start signal S2, random 1
One value is extracted and stored. When 0.128 seconds or 0.130 seconds have elapsed after the start signal S2 was derived, the stored value of Random 1 was read and checked, and 0.132 seconds or 0.134 seconds after the start signal S2 was derived.
One value is extracted from each of random numbers 2, 4, and 5 when the read value of random number 1 is a win when a second has elapsed. This random 2 is, as shown in FIG.
The 40 numbers of "39" change every moment,
"6, shown in FIG. 11 of the hit symbol corresponding to the extracted value
Any of the sequences except "18, 38" is extracted. In addition, the random 4 is, as shown in FIG.
The number of 100 "99" changes every moment, and is a random number for determining the LED to be lit of the decorative LED 44 not directly related to the game. Furthermore,
Random 5 is a random number for selecting five types of variation patterns at the time of hit, and as shown in FIG.
Seven numbers from "0 to 6" are changing every moment.

When the numerical value extracted from Random 1 is "8", it is determined to be a big hit (the big hit in this case is synonymous with the specific game state), and is extracted as Random 2. The symbol corresponding to the selected value is displayed at a predetermined position which is visible to the player. Thus, at the time of deriving the start signal S2, it is determined whether or not the combination of the symbols displayed on the variable display device 40 is a hit, and the symbols displayed at the stop are also determined, and after the determination is finished. (In the present embodiment, 0.172 seconds or 0.174 after the start signal S2 is derived.
After the lapse of seconds), first, the pattern 71a starts to change, and after a short time interval (0.002 seconds), the pattern 71c, the pattern 7
1b sequentially starts changing. Therefore, the variation mode of the symbols 71a and 71c is varied in the same mode as described in FIG.

On the other hand, when it is a hit in the variable display of the symbol 71b, since the stop symbol on the hit line displayed on the symbols 71a, 71c which have already stopped is the hit symbol, it is a variation in the so-called reach state, The fluctuation pattern is changed by the value of the extracted random 5. Specifically, as shown in FIG. 13, when the value of the extracted random 5 is “0 to 2”, the design 71b is
Like the symbols 71a and 71c, the basic time (6.300)
For a second), a predetermined fluctuation speed is set and fluctuates, and when the basic time elapses, once a minute time (0.200 seconds) is stopped, the first re-fluctuation is started and 42 to 62 symbols It is stopped when 21 symbols (one rotation) have changed from the time when the hit symbol coincides with the variation (this variation pattern is referred to as a variation pattern). The fluctuation speed during this period is set to a slightly slow fluctuation speed. Further, when the value of the extracted random 5 is “3”, after the fluctuation pattern described above is finished (however, the latter half of the first re-changing is 20
(Variation of the symbol), after stopping for a minute time (0.490 seconds), the second re-variation is started and the symbol is changed by one symbol and stopped (this variation pattern is referred to as a variation pattern). Similarly, when the value of the extracted random 5 is “4”, after the fluctuation pattern described above (however, the latter half of the first re-changing is a fluctuation of 19 symbols), a minute time (0.490)
Second) After stopping, the second re-fluctuation is started, and it is fluctuated by two symbols and stopped (this fluctuation pattern is called fluctuation pattern), and when the value of the extracted random 5 is "5", the above fluctuation After the end of the pattern (however, the second half of the first re-variation is a variation of 22 symbols), a small time (0.49
(0 seconds) After stopping, the second re-variation is started, and 20 symbols are varied and stopped (this variation pattern is referred to as a variation pattern), and when the value of the extracted random 5 is “6”, the above is performed. After the fluctuation pattern is completed (however, the latter half of the first re-fluctuation is a fluctuation of 21.875 symbols), after being stopped for a minute time (0.490 seconds), the second re-fluctuation is started and is 0.875. The design is changed in the opposite direction and stopped (this change pattern is called a change pattern). That is, in this variation pattern, the sum of the number of variation symbols in the second half of the first time and the number of variation symbols in the second time is “21 × n (n =
1) ”.

Next, the value extracted by Random 2 is "6".
The variable display operation when the random number is 2 will be described with reference to FIG. 14. When the value of random 2 is “6”, as shown in FIG. 11, “JK” is displayed on the hit line 2 (diagonal line to the lower right). This is the case when jackpot symbols are lined up. At this time, in the reach state, the symbols appearing on the left and right symbols 71a and 71c on the hit line 4 (diagonal line to the upper right) are the big hit symbol "7 (red)", and in the state where the left and right symbols 71a and 71c are stopped. , The double reach state in which the reach state appears on the two lines of the hit lines 2 and 4, but in the end, the "JK" of the design 71b is controlled so as to stop at the center. is there. Then, in FIG. 14, the variation mode of the symbols 71a and 71c is exactly the same as that of FIG. 13, and in the variation of the symbol 71b, the patterns of the second re-variation in the big hit pattern are also the same. 13 differs from the variation pattern in the latter half of the first re-variation. That is, in the pattern, the fluctuation is stopped at the time when it changes by 2 symbols after it coincides with “7 (red)” during the fluctuation of 42 to 62 symbols by the first re-variation. After two symbols of "7 (red)", "JK" is displayed. Therefore, "JK" is displayed when the variation of the symbol 71b is stopped. In this fluctuation pattern, the sum of the number of fluctuation symbols in the latter half of the first time and the number of fluctuation symbols in the second time (this is constant for each pattern) is “2.
The variation is controlled so that it becomes 1 × n (n = 0, 1) +2 ”. The patterns (1) to (3) shown in the figure are set on the basis of such a variation idea, and detailed description thereof will be omitted.

Next, the value extracted by random 2 is "1".
Regarding the variable display operation when it is "8" or "38", FIG.
With reference to FIG. 11, when the value of Random 2 is “18”, as shown in FIG. 11, the big hit symbols of “J” are arranged on the hit line 4 (diagonal line to the upper right).
At this time, in the reach state, the symbols appearing on the left and right symbols 71a and 71c on the hit line 2 (diagonal line to the right) are:
It is a big hit symbol "7 (blue)", and the left and right symbols 71a,
In the state in which 71c is stopped, a reach state appears on the two lines of the hit lines 2 and 4, but it is a double reach state, but finally, "J" of the design 71b is stopped at the center. It is controlled by. Further, when the value of Random 2 is “38”, as shown in FIG. 11, it is a case where the big hit symbols of “K” are arranged on the hit line 4 (diagonal line to the upper right). At this time, in the reach state, the left and right symbols 71 on the hit line 2 (diagonal line falling to the right)
The symbols appearing on a and 71c are "7 (red)" of the jackpot symbol.
In the state where the left and right symbols 71a and 71c are stopped, the reach state appears on the two lines of the hit lines 2 and 4, and the double reach state appears. The "K" is controlled so as to stop at the center.

Then, in FIG. 15, the symbols 71a,
The variation mode of 71c is exactly the same as that of FIG.
In the variation of the pattern 71b, the pattern of the second variation again in each of the big hit patterns to is the same.
13 differs from the variation pattern in the latter half of the first re-variation. That is, in the pattern, 1
During the fluctuation of 42-62 symbols at the second re-changing, "7
(Blue) ”or“ 7 (red) ”and the fluctuation is stopped at the time when 19 symbols have changed. After 19 symbols of "7 (red)", it is "J" or "K". Therefore, symbol 7
"J" or "K" is displayed when the fluctuation of 1b is stopped. In this variation pattern, the sum of the number of variation symbols in the latter half of the first time and the number of variation symbols in the second time (this is constant for each pattern) is “21 × n (n = 0, 1) +19”. The fluctuation is controlled as described above. The patterns (1) to (3) shown in the figure are set on the basis of such a variation idea, and detailed description thereof will be omitted.

Incidentally, the rotary drum 71a in this embodiment.
71c is an interval time (about 2) between the opening and closing of the opening / closing plate 9 of the variable winning ball device 6 in the specific game state.
Also in the second), as shown in FIG. 16, 21 symbols (1
By changing the rotation, the player's eyes are entertained.

Although the structure and operation of the embodiment have been described above, the variable display device 40 according to this embodiment has a connection opening 65 for connecting the wiring 101 extending from the stepping motor 99 or the drum lamp 96 to the outside. Is formed on the lower surface of the drum device housing 53, and the connector 84 a of the wiring 101 and the external relay board 1 are provided through the connection opening 65.
No. 02 connector 103 is connected, the relay board 102 and the collective wiring 106 are different from those in which the conventional connection opening 65 is provided on the rear surface of the drum device housing 53. Since it is not provided on the rear surface, the amount of protrusion to the rear can be suppressed, and even if the rotating drum 71 is made larger than before, when the pachinko gaming machine is installed on the pachinko island, its rear protruding portion interferes. It won't fit.

In the above-described embodiment, the three drum units 70 are housed in the drum unit housing 53, but the drum unit housing 53 in which less than or more than the rotating drum units 70 are housed may be used. Good. Further, in the above-described embodiment, the drum lamp 96 is shown as the electric drive source included in the rotary drum unit 70 in addition to the stepping motor 99 including the drum sensor 108, but at least a motor for rotationally driving the rotary drum 71 is included. It should be composed of.
