2. Description of the Related Art Conventionally, in ball game machines such as a pachinko machine and an arrangement ball game machine, a winning hole in which a hit ball wins, a downflow path of a winning ball in which a hit ball which flows in the winning hole flows down, and a downflow of the winning ball. A prize ball sensor which is located on the way of the hit ball on the road and detects a hit ball flowing down the prize ball flow path for each ball, and a profit giving means for giving a profit to the player based on a detection signal from the prize ball sensor And those with

[0003] The above-mentioned conventional winning ball sensor comprises a proximity sensor or the like, and when detecting a hit ball hitting the winning opening, outputs an electric signal. It gives the player benefits such as emissions, special rights and lamp lighting.

[0004]

However, the above-mentioned winning ball sensor may operate not only when a hit ball is detected but also by radio waves transmitted from a radio device or the like.
For this reason, fraud prevention measures such as electrically shielding the prize-ball sensor and the electronic circuit are taken so that the prize-ball sensor does not operate by radio waves transmitted from a small-output radio such as a handy radio. However, the prize ball sensor malfunctions due to radio waves transmitted from the high-output wireless device, and fraudulent acts cannot be completely prevented.

In order to prevent the malfunction of the winning sphere sensor due to the high-output wireless device, a method of installing another equipment such as a radio wave detector may be considered. However, this method requires new construction and requires additional equipment. There is a problem that the cost increases. Further, there is also a case where a radio wave for in-store broadcasting, a civic band radio device, an amateur radio device, or the like also reacts to a radio wave that is properly transmitted, which makes it difficult to adjust the sensitivity of the radio wave.

Accordingly, the present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to detect a malfunction of a winning ball sensor due to an illegally transmitted radio wave. An object of the present invention is to provide a simple and inexpensive device that can surely prevent fraud.

[Operation] The hit ball that wins the winning opening (50) is the winning ball down the road
Flow down (60). This hit ball is the first winning sensor (21)
And the first winning sensor (21) outputs a first detection signal of the hit ball. Thereafter, the hit ball is detected by the second winning sensor (22), and the second winning sensor (22) outputs a second detection signal of the hit ball. That is, the generation of the first detection signal output by the first winning sensor (21) and the generation of the second detection signal output by the second winning sensor (22) are temporally shifted.

On the other hand, the first winning sensor (21) and the second winning sensor (22) are simultaneously operated by radio waves transmitted from a wireless device or the like, and the first detection signal output from the first winning sensor (21) is output. And the generation of the second detection signal output by the second winning sensor (22) are temporally coincident with each other. For this reason,
The fraud determining means (40) includes a first winning sensor (21) and a second winning sensor (21).
Compare the time of occurrence of both detection signals of the hit ball output by the winning sensor (22), and if the occurrence of both detection signals is temporally shifted, it is determined that the detection signal is a regular hit ball as described above. to decide.

On the other hand, when the generation of both detection signals coincides with each other in time, it is a signal other than the normal hit ball detection signal,
The fraud determining means (40) determines that fraud has occurred, and outputs a fraud signal to the profit provision means (30). The profit giving means (30) stops giving the profit. Therefore, according to the first aspect of the present invention, it is possible to detect the malfunction of the winning ball sensor due to the improper radio wave and reliably prevent the improper operation by using the inexpensive and simple equipment without largely modifying the conventional equipment. .

FIG. 1 is a schematic block diagram of a fraud prevention device, and FIG. 2 is an explanatory diagram showing the structure of a winning ball sensor. 3 is a time chart showing the output of each detection signal due to the regular winning of the hit ball, and FIG. 4 is a time chart showing the output of each detection signal due to the illegal act.

A game machine fraud prevention apparatus 10 according to the present invention.
As shown in FIG. 1, a first prize sensor 21 and a second prize sensor 22 which constitute a prize ball sensor 20 and detect a hit ball B are formed.
A first detection signal a output from the first prize sensor and a second detection signal b output from the second prize sensor, which are located between the two prize sensors 21 and 22 and the profit giving means 30. When the detection signals a and b are temporally coincident with each other, a fraudulent signal is output, and the fraudulent judging means 40 for stopping the profit provision in the profit provision means 30 is mainly used. It is a component. Also, on the output side of the fraud prevention device 10, both detection signals a,
Profit giving means 30 for giving a profit to the player based on b is connected.

The first winning sensor 20 and the second winning sensor
Reference numeral 22 includes a proximity sensor that detects a passing ball and outputs a signal. Specifically, when the hit ball passes, the first winning sensor outputs a first detection signal a, and the second winning sensor outputs a second detection signal b. This first winning sensor 21
As shown in FIG. 2, the second prize sensor 22 is located in the middle of the flow of the hit ball on the prize ball flow path 60 provided with the prize port 50 where the hit ball wins, and the first prize sensor 21 is connected to the second prize sensor. It is provided to be located upstream of 22. Both the winning sensors 21 and 22 are formed so as to be able to detect each hit ball flowing down the winning ball flow path 60.

The two winning sensors 21 and 22 need only be provided vertically above and below the direction in which the hit ball B flows.
After the first detection signal a of the winning sensor 21 falls, the second
It is preferable to provide the second detection signal b of the winning sensor 22 at an interval larger than the diameter of the hit ball B so as to rise. With this arrangement, the detection signals a,
This is because the temporal comparison of the occurrence of b becomes more reliable.

In the embodiment described above, the two winning sensors 21 and
Although the pass-through type proximity sensor 22 is used, the winning sensors 21 and 22 may be any devices as long as they can detect a hit ball and output a detection signal, such as an optical sensor or a micro switch. . The profit giving means 30 gives a profit to the player, and includes, for example, a means for discharging a prize ball, giving a special profit, and lighting a lamp.

The injustice judging means 40 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM
(Random access memory), and a microcomputer including an input / output interface. As shown in FIG. 1, a first winning sensor 21 and a second winning sensor 22 are electrically connected to the injustice judging means 40, and the detection signals of the hit ball B from the two winning sensors 21 and 22 are received. Is entered.

A procedure for judging an improper act by the improper act judging means 40 will be described below. The hit ball B which won the winning opening 50
Flows down the prize ball flow path 60 and is first detected by the first prize sensor 21, and the first prize sensor 21 outputs a first detection signal a of the hit ball B. The hit ball B flowing down the winning ball flow down path 60,
Further, the second winning sensor 22 detects the hit ball, and the second winning sensor 22 outputs a second detection signal b of the hit ball.

As described above, when the winning opening 50 is properly won, as shown in FIG. 3, the detection signals a and b output by the two winning sensors 21 and 22 become the first signals of the first winning sensor 21. The output of the detection signal “a” precedes the output of the second detection signal “b” of the second winning sensor 22, and its generation is shifted in time. On the other hand, a radio wave transmitted from a wireless device or the like reaches the first winning sensor 21 and the second winning sensor 22 at the same time, and simultaneously operates the two winning sensors 21 and 22, as shown in FIG.
The detection signals a and b output by the two winning sensors 21 and 22 are signals whose generation coincides in time.

The injustice judging means 40 detects the first detection signal a and the second detection signal of the hit ball B output from the first winning sensor 21 and the second winning sensor 22 based on the operating characteristics of the two detection signals a and b. The occurrence of the signal b is compared temporally. Then, when the generation of the two detection signals a and b is temporally shifted,
As described above, it is determined that the signal is a detection signal from a regular hit ball B.

If the fraud judging means 40 judges that the signal is a detection signal of a regular hit ball B, the profit giving means 30 discharges a prize ball, generates a special right, or turns on a lamp, for example. And give the player a profit. on the other hand,
When the first detection signal a and the second detection signal b are temporally coincident with each other, the two winning sensors 21 and 22 are not detected by the normal hitting ball B but by radio waves transmitted from a wireless device or the like. It is determined that a malfunction has occurred and that an illegal act has occurred.

When the fraud judging means 40 judges that the fraud has occurred, the profit giving means 30 stops giving the profit to the player. In this case, a fraudulent alarm device (not shown) such as a light emitting device or a buzzer is operated,
The game store clerk may be notified that the misconduct has occurred.
Note that the comparison between the two detection signals a and b output by the two winning ball detection sensors 21 and 22 by the injustice judging means 40 of the above embodiment is as follows.
The rise or fall of each of the detection signals a and b may be compared, or the whole may be compared, or both signals may be combined to break the total time. Good.

Further, the detection signals a and b of the hit ball B that has been properly won are the first detection signal a of the first winning sensor 21 being the second detection signal a.
Since the second detection signal b of the winning sensor 22 precedes the second detection signal b of the winning sensor 22, the reverse case, ie, when the second detection signal b of the second winning sensor 22 precedes the first detection signal a of the first winning sensor 21, It can also be determined that a fraudulent action to reverse the hit ball B has occurred.

Further, in the above-described embodiment, the winning ball sensor 20 has been described as being composed of two sensors, the first and second winning sensors. However, the winning ball sensor 20 has at least a plurality of sensors. And in different embodiments, for example, it may be composed of first, second and third three sensors.

[0024]

Since the present invention is configured as described above, it has the following effects. Claim 1
According to the described invention, on the winning ball down road where the hit ball flows down,
Two winning sensors are arranged side by side in the downflow direction of the hit ball, and the time transition of a detection signal generated when both winning sensors detect the hit ball is determined by the fraud determining means to detect fraud. .

Therefore, it is possible to transmit radio waves from a wireless device or the like by using a simple and inexpensive device without adding new equipment such as a radio wave detector or electrically shielding a winning ball sensor or an electronic circuit. By making the winning ball sensor malfunction, it is possible to reliably prevent fraudulent acts that illegally profit.
