Next, the game of the pachinko machine 1 having the variable winning device 12 and the variable display device 10 as described above will be briefly described.

When power is turned on, a CPU (not shown)
The electric control device of the configuration performs initial settings such as clearing of the built-in RAM and checking of each part, and if there is no abnormality, each symbol display device displays a mark.

Then, when a hit ball fired by the player flows into one of the starting ports 11 provided in the game section 5 'and a starting port switch (not shown) provided in the starting ports 11 is turned on, In response to a command from the electric control device, each symbol display device starts changing display and stops after a predetermined time. That is, the left symbol display device circulates and displays the ＄ mark and the numerals 1 to 9 as a display symbol for a predetermined moving time, and the middle symbol display device displays the ＄ mark and the numerals 1 to 9 and F, H, J as the display symbols. ,
The characters P and O are cyclically displayed for a predetermined moving time, and the right symbol display device displays the symbol 及 び and the numbers 1 to 9 as well as F, H, J,
The P character is cyclically displayed for a predetermined moving time. Hereinafter, the above-mentioned mark, numerals and characters are simply referred to as symbols.

When the starting port switch is turned on, the electric control device performs a jackpot determination process. The jackpot determination process includes a first jackpot determination random number sequence (0 to 14), a second jackpot determination random number sequence (0 to 14), and a winning number selection random number sequence (0
-5), the winning symbol random number sequence (0-9) is
Each time the addition process is repeated, the value of the random number sequence for selecting a winning number at the time when the ball flows into the starting ports 11... Is stored, and the predetermined numerical value of the first random number sequence for determining a big hit corresponding to the stored value is stored. Numerical values per each. Then, the value of the second big hit determination random number sequence at the time when the ball flows into the starting ports 11 and the first big hit determination at the time when a predetermined time (for example, 5 seconds) has elapsed since the start of the symbol variation display. The "big hit" or "miss" is determined based on the numerical value of the random number sequence for use. It is to be noted that a maximum of four winning combinations can be stored in the starting openings 11..., And the numeric value of the second big hit determining random number sequence at the time of the winning is stored. The numerical value is not stored. Therefore, the hit value of the first big hit determination random number sequence is not changed. If there are four prize memories and the prize is further entered in the starting openings 11..., The memories are erased in chronological order and updated to the numerical value of the second big hit determination random number sequence at the time of the new prize.

If the numerical value of the first big hit determination random number sequence and the second big hit determination random number sequence are predetermined numerical values, it is determined to be "big hit". For example, when the winning opening 11a is won, the numerical value of the random number sequence for selecting a winning number is “0”, the numerical value of the first random number sequence for determining a big hit is “0”, and the numerical value of the second random number sequence for determining a big hit is The case of “0” is referred to as “big hit”. And "big hit" regardless of the numerical value of the random number sequence for hit numerical value selection
Is set so that the probability of becoming becomes approximately 1/200. still,
The stop symbol of each symbol display device is determined based on the numerical value of the random symbol sequence for the hit symbol at the time when a predetermined time has elapsed since the symbol display device started the variable display, for example, the numerical value of the random number sequence for the hit symbol is " At the time of "0", each symbol display device displays a mark and stops.

If the values of the first big hit determination random number sequence and the second big hit determination random number sequence are not a predetermined combination, "out"
Becomes However, when only the first big hit determination random number sequence is a hit number, the left symbol display device and the middle symbol display device stop at a matching symbol. In this case, the stop symbol of the left symbol display device and the middle symbol display device is determined by the numerical value of the hit symbol random number sequence at the time when a predetermined time has elapsed since the symbol started the variable display, and the first symbol at the same time is determined. The right symbol display device stops at the corresponding symbol in the off symbol table based on the numerical value of the symbol for random number (0 to 12).

If the numerical value of the first big hit determination random number sequence is not a predetermined numerical value, a second out-of-design symbol random number sequence group at the time when a predetermined time has elapsed since the start of the variable display of the symbol, ie, the left symbol Each symbol is displayed with a symbol corresponding to the second symbol random number sequence (0-9) for the second symbol, the second symbol random number sequence for the middle symbol (0-14), and the second symbol random number sequence for the right symbol (0-14). The device stops. Combinations of "big hits" and combinations in which the left symbol matches the middle symbol are excluded.

As described above, each symbol display device is stopped, and after about one second, a combination is determined based on the stopped symbols. When the symbols displayed by each symbol display device are aligned,
That is, in the case of "big hit", the special winning opening 17 is opened.
The opening of the special winning opening 17 is performed by driving the drive motor 35, and the movable member 20 is raised by the drive mechanism.
The small wing piece 27 rotates to open the continuous winning opening 25. This open state continues for about 18.5 seconds. However, when a predetermined time elapses or ten balls are won in the special winning opening 17, the drive motor 35 rotates again to move the upper cam 46 to the crank pin 45.
The movable member 20 suddenly returns and slides to close the special winning opening 17. And during the opening, the continuous winning opening 2
5, when the continuation switch 26 is turned on and the opening operation is completed, the opening operation of the movable member 20 is restarted again,
The opening operation can be repeated up to 10 times.

Further, the upper edge piece 28 of the movable member 20 having an inclination and the disposition of the obstruction nails N...
It is also possible to guide a ball that flows down a position outside the winning area between to another winning port. For example, in the case of the gaming board 5 arranged as shown in FIG. 12, the movable board 20 can be guided to the left and right starting ports 11b and 11c at the raised position.

FIGS. 13 and 14 are time charts showing the relationship between the starting port, the symbol display device, and the movable member (large winning opening).

Although the present invention has been described with reference to the embodiment shown in the drawings, the present invention is not limited to the above-described embodiment, and can be appropriately implemented unless the structure described in the claims is changed. For example, although a liquid product is shown as a display element, another electrical display element such as a light emitting diode may be used.
