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.

[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 controls the display of a display device such as an electronic display or a light emitting diode in accordance with a clock signal of an electronic control circuit board, counts the clock signal with a counter, and determines whether a hit ball is hit. In a pachinko gaming machine configured to generate a jackpot with a predetermined probability by continuously obtaining a big win by obtaining a count value of the counter as a random number when winning at the winning opening of The display is controlled by a clock signal that is irregularly thinned out.
Further, the present invention is characterized in that, in the pachinko gaming machine, display control is performed on a display device by a clock signal thinned out irregularly during waiting for a customer and / or during a jackpot period.

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
The clock signal (5) transmitted from the pulse generator
CPU, RAM, ROM operated by about 00Hz)
And the like. A signal line 17 extends from the electronic control circuit board 16 to the illumination lamp 6, the illumination light emitting diode 7, and the like, and a signal line 18 extends to the electronic display 8. Reference numeral 19 denotes a signal line connected 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.

The electronic control circuit board 16 is provided with a counter capable of counting the clock signal transmitted from the pulse generator, for example, up to 200 pulses. The counter always counts the clock signal. The count value of the counter when the winning opening 10 is won and the start switch 11 detects this is acquired as a random number, and a big hit is generated when the random number is a predetermined number. Incidentally, if one of the counted values is a big hit, the probability of the big hit occurring is 1/200.

When a big hit occurs, the solenoid 14 is operated to open the big winning opening 12, and when 10 hit balls enter the big winning opening or after 30 seconds elapse, the big winning opening is closed, but the big winning opening is closed. V provided in the winning opening
When a hit ball wins in a continuous winning opening called a zone, the special winning opening is similarly continuously opened up to about 16 times thereafter, so that a large number of hit balls can win during this jackpot period. Become.

Thus, in the present invention, the electronic control circuit board 16 is controlled so that display devices such as the illumination lamp 6, the light emitting diode 7, and the electronic display 8 are controlled by a clock signal which is irregularly thinned out. By changing and transmitting the clock signal inside to these input / output devices 20,
These display devices are not controlled by the clock signal.

The fluctuation of the clock signal due to such thinning is caused only when the pachinko gaming machine is waiting for a customer (that is, when not in use) and a demonstration of waiting for a customer is being displayed on the electronic display 8, and only during the jackpot period. This may be done. FIG. 4 shows a time chart in which the clock signal for controlling the display of each display device is thinned out during the waiting time for the customer and during the jackpot period. That is, as shown by the symbol A in FIG.
The clock signal for operating U is a regular pulse signal transmitted from the pulse generator, while the clock signal for controlling the display device indicates to B that the customer is waiting,
The clock signal is irregularly thinned out as shown in FIG.

The illumination lamp 6, the light emitting diode 7
And the like may have a self-blinking function, and may be made to self-blink as necessary during these periods. In the case of the electronic display 8, as shown in C, during the jackpot period, for example, when the large winning opening 12 is won, the clock signal a is transmitted and the number of hit balls winning the large winning opening 12 reaches a predetermined number. For example, when there is a data change, display control data necessary for updating an image may be transmitted. FIG. 5 illustrates a flowchart of the transmission process in such a case.

In this way, by controlling the display of each display device by the clock signal thinned out irregularly, the relationship between the display fluctuation such as blinking of each display device and the count value of the counter is eliminated. Therefore, even if the hit ball is made to win in the winning opening 12 in consideration of the timing of the display change, the probability that a big hit occurs will not be improved.

Also, even if the electronic circuit for remodeling is mounted by branching the signal lines 17 and 18 wired from the electronic control circuit board 16 to each display device, a clock signal obtained from these signal lines is provided. 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.

[0018]

As described above, the pachinko gaming machine of the present invention is
By controlling the display of an electronic display, a light emitting diode or the like with a clock signal thinned out irregularly, even if a display of the display device or a clock signal for controlling the display is used, a big hit may occur. Since the occurrence probability cannot be changed at all, there is a beneficial effect that the occurrence of the jackpot can be reliably prevented from being illegally controlled.
