DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine configured to obtain a large number of prize balls at a time by generating a jackpot, and more particularly, to prevent a jackpot from being illegally generated. Is to do so.

[0002]

2. Description of the Related Art In general, "desipati" and "fever machines"
Conventional so-called first-class pachinko gaming machines called
A microcomputer including a CPU, a RAM, a ROM, and the like, which is operated by a clock signal transmitted from a pulse generator, is configured on an electronic control circuit board provided in a board case on the back of the game board. Color liquid crystal display provided on the panel, CRT
Display control such as an electronic display and a segment display, an illuminated lamp, a light emitting diode, and the like are controlled according to the clock signal, and the clock signal is counted by a counter, and the hit ball wins a predetermined winning opening. At this time, the count value of the counter is obtained as a random number, and if the random number is a preset number, a jackpot is generated. FIG. 8 is a time chart showing the change over time of the count value of this counter.
When the jackpot occurrence probability is set to 1/200, the minimum value of the count value is set to 0 and the maximum value is set to 199, and any one of 0 to 199 is determined as a numerical value for generating a jackpot.

[0003] When a big hit occurs, "777" or the like is displayed on the electronic display, an electric opening / closing large winning opening is opened, and one hit ball is hit at the large winning opening.
Although the special winning opening closes once when 0 or 30 seconds have elapsed, the special winning opening is closed by a hit ball being placed in a continuous winning opening called a V zone provided in the special winning opening. Is also opened continuously up to about 16 times. For this reason, it is configured such that a large amount of prize balls can be acquired by hitting the ball during the jackpot period, and a lot of profits are brought to the player.

[0004]

Therefore, in this type of pachinko game machine, in a model with a low clock frequency, the player measures the display timing of the display device such as the light emitting diode, and then calculates the count value of the jackpot of the counter. By estimating and matching the timing at which the hit ball is won to the winning opening with the count value, there is a possibility that a big hit can be generated with high probability, and therefore, a special hitting method that matches the timing with the clock signal is used. There was a problem that only the players could get big profits.

In order to make the jackpot easy or difficult to hit, a remodeling electronic circuit is mounted near the substrate case on the back of the pachinko game machine, and a clock signal is transmitted from a signal line for controlling display of the display device to the electronic device. Normal board cases that are generally prohibited, such as taking in the circuit and returning the jackpot signal to the electronic control circuit board in the board case in accordance with the timing of the clock signal, or always returning the non-jackpot signal, are taken. There has been a frequent crime of playing illegal games very easily without replacing the board case with an illegally modified one.

Accordingly, an object of the present invention is to prevent the occurrence of a jackpot from being illegally controlled by utilizing such a display of a display device or a clock signal for controlling the display.

[0007]

For this purpose, the present invention counts a clock signal by a counter, and obtains a count value of the counter as a random number when a hit ball wins a predetermined winning opening, so that a jackpot is determined by a predetermined number. In a pachinko gaming machine configured to generate a winning port continuously with a probability, the counting of clock signals by a counter is stopped irregularly. Further, the present invention is characterized in that the counting of the clock signal by the counter is stopped when an event such as waiting for a customer or a big hit occurs in the pachinko gaming machine. Further, according to the present invention, a clock signal is counted by a counter, and a count value of the counter when a hit ball wins a predetermined winning opening is obtained as a random number, thereby generating a jackpot with a predetermined probability to continuously generate the winning opening. In the pachinko gaming machine configured to be opened in the above, the count value of the counter is rewritten irregularly. Further, the present invention is characterized in that in the above-mentioned pachinko gaming machine, the count value of the counter is rewritten when an event such as waiting for a customer or a big hit occurs.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the front of the pachinko gaming machine. In the figure, 1 is an upper plate for receiving a prize ball, 2 is a lower plate, 3 is a hitting / launching handle, 4 is a gaming board, 5 is a front frame, and 6 is the gaming board. , A light emitting diode for illumination, 8 a liquid crystal display type electronic display, 9 a normal winning opening, 10 a starting winning opening, and a start switch 11 in the winning opening 10. Is provided. Reference numeral 12 denotes a rectangular large winning opening, and an opening / closing door 13 has a solenoid 14 at the large winning opening 12.
It is pivotally supported so that it can be opened and closed forward by the operation of (FIG. 3).

A board case 15 is provided on the back side of the game board 4 as shown in FIG. 2, and an electronic control circuit board 16 is provided in the board case. The electronic control circuit board 16 has a clock signal (50) transmitted from the pulse generator.
(About 0 Hz), a microcomputer including a CPU, a RAM, a ROM, and the like, which operates at about 0 Hz. Then, from the electronic control circuit board 16, the illumination lamps 6,
A signal line 17 is led to the light emitting diode 7 and the like, and a signal line 18 is led to the electronic display 8. Also, 19
Is a signal line wired from the electronic control circuit board 16 to the start switch 11, the solenoid 14, and the like.

FIG. 3 is a block diagram showing the electronic control circuit, in which an illumination lamp 6, an illumination light emitting diode 7, and an electronic display 8 are connected via an input / output device 20. The start switch 11, the solenoid 14, and the like are connected via 21.

A counter capable of counting the clock signal transmitted from the pulse generator is provided on the electronic control circuit board 16, and the counter stops counting non-periodically. FIG. 4 is a time chart showing how the count value of this counter changes over time. In this case, the counting of the clock signal by the counter is stopped when an event such as waiting for a customer or a big hit occurs. Due to this stop, the count value becomes constant during the event period as shown, and when the count period is restarted after the event period ends, the phase of the count value is shifted from the previous phase. FIG. 5 is a flowchart showing this operation.

For this reason, even if the hit ball is made to enter the winning opening in accordance with the display timing of the display device such as the light emitting diode 7, it is not always possible to generate a big hit with a high probability. That is, it is possible to eliminate the relationship between the display fluctuation such as the blinking of each display device and the count value of the counter, so that even if the hit ball is made to win in the winning opening 12 in view of the timing of the display fluctuation, This does not increase the probability of a jackpot.

Further, even if a signal line 17, a signal line 18 and the like wired to each display device are branched from the electronic control circuit board 16 and a remodeling electronic circuit is mounted, a clock signal obtained from these signal lines is obtained. Does not match the clock signal that increments the counter, so that unauthorized alteration that can change the probability of occurrence of a jackpot using this clock signal cannot be performed.

The time when the counting of the counter is stopped is not only during such an event period, but also when a hit ball is won to another winning opening, when the number of hit balls is constant, or the like.
It is possible to do it at any time, but it is desirable that it be performed irregularly.

On the other hand, the time chart shown in FIG. 6 and the flowchart shown in FIG. 7 are such that the count value of the counter is rewritten when an event occurs. That is, the time chart shown in FIG. 6A is shifted in phase by clearing the count value of the counter to zero when an event such as waiting for a customer or a big hit occurs, and the time chart shown in FIG. When such an event occurs, a certain number is added to the count value of the counter so that the phase is shifted.

As described above, the relationship between the display fluctuation such as blinking of the display device and the count value of the counter can be eliminated by rewriting the count value of the counter irregularly, so that a special hitting method can be used. Increase the probability of jackpots and prevent unauthorized modification of electronic circuits.

Note that the count value of the counter when the hit ball wins the winning opening 10 and is detected by the start switch 11 is obtained as a random number, and a big hit occurs when the random number is a predetermined number. This is no different from the conventional method. When a big hit occurs, the solenoid 14 is operated to open the big winning opening 12, and the big winning opening is closed once 10 hit balls enter the big winning opening or after 30 seconds elapse. However, when a hit ball wins in a continuous winning opening called a V zone provided in the winning opening, the winning opening is continuously opened similarly up to about 16 times thereafter. A large number of hit balls can be won during the period.

[0018]

As described above, the pachinko gaming machine of the present invention is
The phase of the count value is shifted by stopping the count of the clock signal by the counter irregularly or rewriting the count value of the counter irregularly, so that the display on the display device or the display thereof is displayed. Even if the clock signal to be controlled is used, the probability of occurrence of the jackpot cannot be changed at all, and there is a beneficial effect that the occurrence of the jackpot can be reliably prevented from being illegally controlled.
