The symbol display device is not limited to a liquid crystal display device, and if a plurality of symbols can be displayed as identification information, a so-called digital display consisting of light emitting diodes (LEDs) of 7 segments, or a dot matrix by LEDs. A system display device or a rotary drum type display device capable of mechanically displaying a pattern may be used.

Next, a pachinko game which is performed based on the identification information determined in the pachinko machine 1 having the above-described variable winning device 12 and the variable display device 10 will be described.

When the 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, the hit ball shot by the player flows into one of the starting ports 11 ... Provided as starting means in the game section 5 ', and a starting port switch (not shown) provided in the starting port 11 ... When turned on, each symbol display device starts a variable display according to a command from the electrical control device, and stops after a fixed time.
That is, the left symbol display device has a $ mark and 1 as a display symbol.
Numbers -9 are cyclically displayed at a predetermined movement time, and the middle symbol display device circulates $ symbols and numbers 1 to 9 and F, H, J, P, O characters as a display symbol at a predetermined movement time. However, the right symbol display device cyclically displays the $ mark, the numbers 1 to 9 and the letters F, H, J, and P at a predetermined movement time.
In addition, hereinafter, the above-mentioned $ mark, number and character are simply referred to as a design.

When the starting opening switch is turned on, the electric control device performs the identification information determination process (big hit determination process). In the identification information determination process, the first jackpot determining random number sequence (0 to 14) and the second jackpot are determined during the remaining time of the program after the electric control device performs a series of processes and is reset by the interrupt signal. Random number sequence for determination (0 to 14),
The winning number selection random number sequence (0 to 5), the winning symbol random number sequence (0 to 9), the addition process is repeated one by one in the above order,
The values of the random number sequence for selecting a hit number at the time when a sphere flows into the starting port 11 are stored, and the predetermined numbers of the random number sequence for determining the first big hit corresponding to the stored values are set as the hit numbers. Then, the numerical value of the second big hit determination random number sequence at the time when the ball flows into the starting port 11 ... And the first big hit determination at the time when a predetermined time (for example, 5 seconds) has elapsed from the start of the symbol variation display Based on the numerical value of the random number sequence for use, the identification information of "big hit" or "out" is determined. It should be noted that up to 4 can be used for the starting port 11 ...
It is possible to memorize individual winnings, and store the numerical value of the random number sequence for determining the second big jackpot at the time of winning the memorized winning, but do not store the numerical value of the random number sequence for selecting a winning numerical value. Therefore, the first
The hit value of the random number sequence for determining big hits is not changed. If there are four winning memories and you win more prizes in the starting port 11 ...
It erases from the oldest memory and updates it to the numerical value of the second big hit determination random number sequence at the time when there is a new prize.

Then, when the numerical value of the first big hit determination random number sequence and the numerical value of the second big hit determination random number sequence are predetermined numerical values, they are used as identification information corresponding to "big hit". For example, when the winning number selection random number sequence at the time of winning the starting opening 11a is "0", the first jackpot determination random number sequence is "0", and the second jackpot determination random number sequence is The case of "0" is used as the identification information of "big hit". And the probability of being a "big hit" is about 1/2 regardless of the numerical value of the random number sequence for selecting a winning numerical value.
Set to 00. In addition, the stop symbol of each symbol display device is determined based on the numerical value of the random number sequence for the winning symbol at the time when a predetermined time has elapsed since the symbol display device started the variable display, and for example, the numerical value of the random symbol sequence for the winning symbol. Is "0",
Each symbol display device displays a $ mark and stops.

When the numerical values of the first big hit determination random number sequence and the second big hit determination random number sequence are other than a predetermined combination, "out"
Identification information. However, when only the first big hit determination random number sequence has a hit value, the left symbol display device and the middle symbol display device stop at the same 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 random number sequence for the winning symbol at the time when a predetermined time has passed since the symbol started the variable display, and the first symbol at the same point The right symbol display device stops at the corresponding symbol in the right symbol pattern table based on the numerical value of the random number sequence for deviation symbol (0 to 12).

Also, if the numerical value of the first big hit determination random number sequence is not a predetermined value, the second out-of-design symbol random number group at the time when a predetermined time has elapsed since the symbol started variable display, that is, the left symbol For second off symbol random number sequence (0-9), second off symbol random number sequence for medium symbols (0-14), second off symbol random number sequence for right symbol (0-14) each symbol display in the corresponding symbol The device stops. The combination of "big hit" and the combination of the left design and the middle design are excluded.

As described above, each symbol display device is stopped, and after about 1 second, the winning combination is determined by the identification information based on the stopped symbols, and when the symbols displayed by each symbol display device are complete, that is, When the identification information of "big hit" is created, the special winning opening 17 is opened. The special winning opening 17 is opened by driving the drive motor 35, the movable member 20 is lifted by the driving mechanism, and the small wing piece 27 is rotated to open the continuous winning opening 25. This open state is about 1
It lasts for 8.5 seconds, but the specified time has passed or the special winning opening 1
When 10 balls are won in 7, the drive motor 35 is rotated again, the crank pin 45 is disengaged from the upper cam 46, and the movable member 20 is rapidly returned and slid to close the special winning opening 17. Then, when the ball flows into the continuous winning opening 25 and the continuation switch 26 is turned on during the opening, after the opening operation is completed,
The opening operation of the movable member 20 is restarted again, and the opening operation can be repeated up to 10 times.

Further, by disposing the upper edge piece 28 of the movable member 20 having an inclination and the appropriately arranged obstacle nails N ... In the movable member 20 movable state, the left and right movable members 20.
It is also possible to guide a ball flowing down from a position outside the winning area between the two to another winning port. For example, in the case of the game board 5 arranged as shown in FIG. 12, the movable member 20 can be guided to the left and right starting ports 11b and 11c at the raised position.

13 to 14 are time charts showing the relationship among the above-mentioned starting opening, the symbol display device and the movable member (large winning opening). That is, in FIG. 13, when the hitting ball enters the starting opening 11 and the starting opening switch is turned on, the random number determining random number value and the second jackpot determining random number value are acquired, and about 5
After a second, a random number value for determining the first jackpot is acquired and a stop symbol is determined. Then, after this stop symbol is determined, it means that the left symbol is stopped at the time of adding 0 to about 550 milliseconds required until the stop symbol determined to be about 50 milliseconds comes around, and the left symbol is stopped. After that, it indicates that the middle symbol will stop at the time of adding 0 to about 860 milliseconds required until the stop symbol decided to about 500 milliseconds comes around, and after the middle symbol stops, about 500 milliseconds It indicates that the right symbol stops at the time of adding 0 to about 800 milliseconds required until the determined stop symbol comes around. In the case of a so-called reach in which the left symbol and the middle symbol match, the reach is slowly changed by taking the time shown in the parentheses to raise the player's expectation. Then, after each symbol is stopped, the winning combination is determined about 1 second later.

Although the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the above-mentioned embodiments and can be appropriately implemented without changing the configuration described in the claims.
