The rotary drum units 60, 70, 80, 90 of the variable display device 30 are controlled by a dedicated sub basic circuit 101. A control signal is supplied from the main basic circuit 100 to the sub basic circuit 101. To be Then, from the sub basic circuit 101, via the drum lamp circuit 109, the drum lamps 66, 76, 85,
95, a drive signal is given to 95, a drive signal is given to the drum motors 63, 73, 83, 93 via the drum motor circuit 110, and drum sensors 68, 78 incorporated in the drum motors 63, 73, 83, 93, From 87 and 97,
Input signals are sent to the sub basic circuit 101 and the basic circuit 100 via the sensor input circuit 111. The devices and circuits other than the drum lamps 66, 76, 85, and 95 described above are supplied with electric power having various voltages from the power supply circuit 112, and the drum lamps 66, 76, 85, and 95 are used for the drum lamps. Electric power having a predetermined voltage is supplied from the power supply 113.

Next, among the game operations controlled by the game control circuit described above, four rotary drums 61, 71,
The operation of determining the stop order of 81 and 91 will be described with reference to FIG. FIG. 8 shows four rotating drums 61, 7
It is a flowchart which shows the operation | movement which determines the stop order of 1, 81, 91. First, in step 10, the rotary drum 6
It is determined whether or not 1, 71, 81, 91 are changing, and if not changing, the subroutine processing is ended without executing the following processing. If changing, in step 20, the upper hit line Left and right rotary drums 61, 7 corresponding to 1
It is determined whether or not the symbol displayed in 1 is the reach display in which the same big hit symbol is displayed. When the upper hit line 1 is not the reach display, there are cases where the lower side is the reach display (including the case where the lower side is the big hit display alone) and the case where it is the out-of-range display. In such a display mode As shown in step 30, the stop order of the rotary drums 61, 71, 81, 91 is “left → right →
It is decided in the order of “up → down”.

On the other hand, when it is determined in step 20 that the upper hit line 1 is reach display, it is determined in step 40 whether the lower hit line 2 is reach display. In this step 40, the lower hit line 2
When it is determined that is not the reach display, the reach display is performed on the upper hit line 1 (including the case where the upper hit alone is the big hit display). Therefore, in the case of such a display mode, step 50 As shown in, the stop order of the rotary drums 61, 71, 81, 91 is determined in the order of “left → right → down → up”.

Further, when it is determined in step 40 that the lower hit line 2 is the reach display, it is determined in step 60 whether the upper hit display is the big hit display, and it is determined that the upper hit display is not the big hit display. If it is determined that it is a big hit display on the lower side in step 70, and if it is determined that the lower side is also not a big hit display (in this case, both the upper and lower sides are not big hits, but reach display). Goes to step 50. On the other hand, when it is determined that the lower side is the big hit display (in this case, the upper side is the reach display and the lower side is the big hit display), the process goes to step 30. When it is determined in step 60 that the upper side is the big hit display, it is determined in step 80 whether the lower side is the big hit display. In this determination,
When it is determined that the lower side is not the big hit display (in this case, the upper side is the big hit display and the lower side is the reach display), the process proceeds to step 50, but when the lower side is also the big hit display (in this case, , Both upper and lower jackpot display)
The rotary drum 6 as shown in step 90.
The stop order of 1, 71, 81, 91 is determined in the order of “left → right → up / down (simultaneous)”.

In the above-mentioned drum stop order determination control, the stop order of the left and right rotary drums 61 and 71 is the same in any case, but the upper and lower rotary drums 81 and 9 are the same.
In 1, in the normal display mode other than the reach display and the big hit display, the display mode is stopped in the order of “up → down” and becomes the reach display or the big hit display (however, the big hit display is prioritized over the reach display) Then, when the reach display or the big hit display is left behind and the vehicle is stopped, and when both of them are the big hit display, the stop control is performed at the same time. Further, in the present embodiment, there is a case where a big hit occurs on one of the hit lines and a case where a big hit occurs on both of the hit lines. However, these values may be the same, but for example, When the simultaneous big hit in the hit line, after the specific game state based on the simultaneous big hit display, until the predetermined condition is satisfied, the appearance probability of the big hit symbol in the variable display operation of the variable display device 30 is It may be improved (for example, 1/230 → 1/100). As the predetermined condition, it can be considered that a specific game state has been set by a predetermined jackpot pattern, that the specific game state has been repeated a predetermined number of times, or that the simultaneous jackpot display is made again. The stop order may be determined by a control different from the stop order determination control described above.

Next, the variable display of symbols that finally stop changing will be described with reference to FIG. FIG. 9 is a flow chart showing the variable display operation of the upper symbol, but the variable display operation of the lower symbol is exactly the same. In the figure, in step 100, it is judged whether or not it is a reach. If it is not a reach, in step 110, it is stopped in a normal stop mode. On the other hand, in the case of reach, it is determined in step 120 whether the value of random 1 is “1”. Random 1 is a random number for determining the hit or miss, for example, the numerical value of "0 to 224" changes every moment,
The jackpot is set when the extracted value is "1". Then, when it is determined in step 120 that the value of random 1 is “1” and it is a big hit, whether or not the value of random 4 (random 5 in the case of the lower symbol) is 2 or less in step 130. Is determined. Random 4 is a random number set corresponding to the design of the upper rotary drum 81 as described above, but in the case of a big hit,
For example, since the winning symbol by the combination of the jackpot symbols selected by the random 6 (not shown) becomes the stop symbol,
Random 4 is used as a random number for determining the re-rotation mode described below. Then, when the value of Random 4 is 2 or less, the re-rotation pattern is only once in step 140 (star in the double circle).
After stopping at, it stops at the winning symbol (the probability is 3 /
19). Similarly, if it is determined in step 150 that the value of random 4 is 7 or less, step 160
After stopping with a re-rotation pattern twice with, it is stopped with a hit symbol (the probability is 5/19), and when it is determined that the value of random 4 is greater than 7, stop with a re-rotation symbol three times in step 170. After doing, it is stopped with a winning design (the probability is 12/19). Thus, in this embodiment,
The number of times of re-rotation is 3 times is the most, and the one in that mode gives the player the impression of approaching the jackpot each time it is re-rotated, so that the interest of the game can be excited.

On the other hand, when the value of Random 1 is not "1" in the step 120, that is, when it is determined that the reach state is finally out, the random 4 is generated in the step 180 (random 5 in the case of the lower symbol). ) Is less than or equal to 2, and when the value of Random 4 is less than or equal to 2, it is stopped with a re-rotation symbol three times in step 190, and then stopped with a deviating symbol (the probability is 3). / 19). Similarly, when it is determined in step 200 that the value of random 4 is 5 or less, the process is stopped by the re-rotation pattern twice in step 210, and then stopped by the deviating pattern (the probability is 3/19), Random 4 value is 8 in step 220
If it is determined that
After stopping at the re-rotation symbol, it is stopped at the out symbol (the probability is 3/19), and when it is determined that the value of Random 4 is greater than 8, the normal mode is performed without re-rotation at step 240. Will be stopped at (probability is 11/1
9).

Although the configuration and operation of the variable display device 30 according to the embodiment have been described above, according to this embodiment, a plurality of types of symbols are formed with different sizes, and the sizes of the symbols are different. Corresponding to the above, the stepping motor driving step intervals between the symbols are made non-uniform, so that even if a part of a plurality of symbols is formed to be extremely large, the large formed identification information can be accurately displayed. Thus, it is possible to attract the player's attention to the variable display operation.

The variable display device 30 is shown to have two rotating drums that rotate in the vertical direction and two rotating drums that rotate in the horizontal direction, and is formed as a rotating drum that rotates in the horizontal direction. Although the size of the identification information and the number of drive steps are changed, the size of the identification information and the number of drive steps formed on the rotating drum that rotates in the vertical direction may be changed. However, in this case, the display window must be formed so that the number of pieces of identification information visible to the player on one rotating drum is one. This is because the identification information is not formed at equal intervals. Further, the gaming machine to which the variable display device is applied may be a gaming machine other than a pachinko gaming machine (for example, an arrangement type ball game machine or a slot machine).

[0042]

As is apparent from the above description, according to the present invention, a plurality of types of identification information are formed with different sizes, and each identification information corresponding to the size of the identification information. Since the stepping motor driving step intervals between them are made uneven, even if a part of the plurality of pieces of identification information is formed to be extremely large, the large formed identification information can be accurately displayed. The player's attention to the action can be drawn.
