BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine in which a jackpot is continuously opened when a jackpot occurs and a special game state is established. And a device for preventing fraudulent acts such as opening a ball.

[0002]

2. Description of the Related Art As is well known, a first-class pachinko gaming machine commonly called a "fever machine" is a type of pachinko game machine such as a color liquid crystal display, a CRT or the like, which is provided with a hit ball in a starting winning hole provided in a game board. When the symbol fluctuation indicator stops displaying after changing the symbol for a certain period of time, and when the stopped symbol becomes a specific symbol such as "777" with a certain probability by chance, it becomes a special game state (big hit) and opens and closes the big winning opening The door is opened by the operation of the electric switchgear,
A predetermined number of hit balls (usually 10
When a predetermined time limit (usually 30 seconds) elapses after the ball is thrown in or in the open state, the so-called first round is over and the special winning opening is closed once. In the case where a hit ball has entered the continuous winning opening (referred to as V zone) provided in the second round, the second round starts and the large winning opening is opened again immediately. A predetermined number of hit balls (usually one hit) are
0) When a ball is thrown in or a predetermined time limit (usually 30 seconds) elapses in the open state, the second round is over and the special winning opening is closed again, but during the second round, the special winning opening is closed. When a hit ball has hit the provided continuous winning opening (referred to as V zone), the third round starts and the large winning opening is opened again immediately. In this way, the large winning opening is continuously opened until the final round (for example, the 16th round), provided that a hit ball has been won in the continuous winning opening during each round.

As shown in FIGS. 2 to 4, reference numeral 12 denotes a rectangular large winning opening formed in the center of the mounting substrate 13, and the large winning opening 12 is provided with an opening / closing door 14 which can be opened and closed forward. ,
It is pivoted by 15. Reference numeral 16 denotes an electric opening / closing device (solenoid) provided on the back side of the mounting board 13. A pin 18 projects from an ear piece 17 integrally provided on the back side of the opening / closing door 14, and an operation shaft of the electric opening / closing device 16. The projections 20 and 21 are formed on the linking piece 19 fixed to the
By being positioned between 0 and 21, the opening and closing door 14 is opened and closed by the operation of the electric opening and closing device 16. 2
2 is a continuous winning opening provided in the center of the winning opening 12,
Reference numeral 23 denotes a continuous winning opening switch for detecting a game ball winning the continuous winning opening 12, and reference numeral 24 denotes a winning ball counting switch for detecting a gaming ball winning the large winning opening 12.

On the back side of the pachinko gaming machine, a game control circuit board 25 for operating the symbol change display 7 and the electric opening / closing device 16 is provided.
As shown in the block diagram of FIG. 5, a start winning opening switch 26 provided in the starting winning opening 9 and the continuous winning opening switch 23 and the winning ball counting switch 24 respectively output electric signals of a game ball winning. receive. Numeral 27 denotes a numeric display comprising two 7-segment displays provided on a curtain plate above the pachinko gaming machine as shown in FIG.
Reference numeral 8 denotes an alarm device including an alarm lamp.

The game control circuit board 25 is activated by an electric signal from the starting winning opening switch 26 and has a jackpot generating means for bringing a special game state with a predetermined probability by chance, a game control means, a display driving means, It comprises sound effect generating means, drive control means and the like. Then, in response to a command signal from the game control means, the symbol variation display 7, the speaker 4, the electric switchgear 16, the numeric display 27, the alarm 2
8, and a prize ball dispensing device (not shown) are operably connected.

FIG. 6 is a flowchart showing the operation of the pachinko gaming machine according to the present invention, and the operation will be described with reference to this flowchart. The pachinko gaming machine captures a winning signal from the starting winning port switch 26 and receives a symbol change display 7
During the loop of the normal game state of step d for determining whether or not the stop symbol becomes a specific symbol such as "777" and a jackpot has occurred. Step a is provided for detecting whether or not a game ball has entered the mouth 12.

When the stop symbol of the symbol change indicator 7 becomes a specific symbol such as "777" at this step d and a big hit occurs, a special game signal is transmitted (step e) to enter a special game state and a big prize. The mouth 12 is opened. (Step f). In this open state, the elapsed time from the opening state is measured by the timer, the number of hit balls hitting the special winning opening 12 is counted by the winning ball counting switch 24, and a predetermined time limit (30
When the second) elapses or when a predetermined number (10) of hit balls hit the special winning opening 12, the special winning opening 12 is closed once. (Steps g and h). However, when the hit ball that has won the special winning opening 12 has won the continuous winning opening 22 and the number of continuations, that is, the number of opening and closing of the special winning opening 12 is a predetermined number (16
If the number of times has not been reached, step j to step f
And the special winning opening 12 is opened again. Therefore, as long as this continuation condition is satisfied, the special winning opening 12 is repeatedly opened up to a maximum of 16 times (16 rounds), during which the player can acquire a large number of premium balls. Note that the actual number of hit balls and the number of rounds in each round are sequentially displayed on the symbol variation display 7, and the player can proceed with the round with reference to the display.

On the other hand, when the winning ball counting switch 24 is operated and the passing of the game ball is captured during the normal game state of the above steps a to d, the process exits from the loop and shifts to step k. The number of game balls counted by the winning ball counting switch 24 is displayed on the numerical display 27, and at the same time, the alarm 28 is operated to display the abnormal state. (Steps l, m).

At the same time, the prize ball payout device of the pachinko game machine is switched to the return mode, and the same number of game balls counted by the winning ball counting switch 24 are returned to the player. (Step n). This abnormality detection state continues until the reset switch provided on the back of the pachinko gaming machine is operated. (Step o).

As described above, by detecting that a game ball has entered the special winning opening 12 when the special game state is not established, the alarm 28 is activated and it is possible to immediately detect that an illegal act is being performed. The number of illegally won game balls is displayed on the numeric display 27, and the illegally won game balls are returned by operating the premium ball payout device provided in the pachinko game machine. It only returns game balls to fraudulent players and does not pay out any extra prize balls, so there is no benefit to fraudulent players, and this has the effect of preventing fraudulent acts. .
