Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an electromagnetic wave in a game store for preventing a game machine installed in a game store from malfunctioning due to an electromagnetic wave output from a wireless communication device or the like. The present invention relates to a malfunction prevention system for a gaming machine.

<Prior Art> In recent years, with the progress of electrotechnology, small and high-performance portable wireless communication devices have been developed, and a player visiting a game store may have a wireless device or the like.

However, recent gaming machines installed in game arcades,
Mainly equipped with electrically driven gaming devices,
Since the control device that controls the operation of these gaming machines is composed of various electronic devices that operate with low electricity, the control devices are easily affected by electromagnetic waves, and it is not desirable that various electromagnetic waves repel in the game store. .

Further, there are some inexplicable players who try to illegally obtain a gaming profit by intentionally causing a malfunction of the gaming machine due to such an electromagnetic wave.

For the reasons described above, a method of enclosing the control device in a grounded conductive case has sometimes been adopted as a measure for preventing a malfunction of the control device of the gaming machine. In this way, it is possible to prevent the electromagnetic wave from directly affecting the control device including various electronic devices.

<Problems to be Solved by the Invention> However, since the electric wiring connecting the gaming machine and the control device of the gaming machine is not particularly provided with an electromagnetic wave countermeasure, a lead wire or the like connecting the gaming machine and the control device is not provided. In some cases, the antenna may function as an antenna, and no effective countermeasures have been taken against a malfunction of the gaming machine caused by external noise entering through such a connection portion.

If an extremely expensive shielded cable is used as the connection line between the game device and the control device, the mixing of external noise can be suppressed, but a game device requiring a considerable number of connection lines in a small in-flight area is required. The use of a shielded cable with a large diameter and a large diameter for a machine is hardly realistic because of the price and difficulty in designing and assembling.

Moreover, in recent gaming machines, electronic devices that are easily affected by electromagnetic waves are used not only in control devices but also in gaming devices and detectors, and the number of factors that cause malfunctions of gaming machines is increasing.

Therefore, a brief description will be given of an outline in which an electromagnetic wave is caused in a gaming machine by a player bringing a wireless communication device to a game store and transmitting an electromagnetic wave.

For example, in a sphere detection circuit 26 as shown in FIG.
That is, one terminal T1 of the normally-open microswitch 27 facing the starting port and the special winning port that gives a player a profit by winning a ball is connected to the pachinko machine control device via the relay board 28. Connect to the + power supply side V of 29,
The other terminal T2 is grounded on the main board 29 side via the relay board 28, the high potential side of the main board 29 is connected to the Schmitt inverter 31 via the CR filter 30, and the output of the Schmitt inverter 31 is connected to the pachinko machine. Constituting the control unit
In the ball detection circuit 26 input to U, the microswitch 2
In a normal state where the ball 7 is not detecting a ball, the contact is open, so that the ball detection circuit 27 is not grounded and the potential at the point a on the input side of the Schmitt inverter 31 becomes high (H),
Low (L) at point b on the output side of Schmitt inverter 31
Becomes Therefore, no ball detection signal is sent to the CPU.

On the other hand, when the ball that has flowed into the starting port or the like activates the micro switch 27 to close the contact, the ball detection circuit 26 is grounded and the point a on the input side of the Schmitt inverter 31 becomes L,
Schmitt inverter 31 outputs H output as ball detection signal to CP
Send to U. Then, the CPU receiving the ball detection signal provides a profit to the player by opening a special winning opening according to a predetermined program.

By the way, when the radio device TX or the like is operated in the vicinity of the ball detection circuit 26 to emit an electromagnetic wave, a wiring 32 connecting the micro switch 27 and the relay board 28 and a wiring 33 connecting the relay board 28 and the main board 29 are a kind. This wiring 3 acts as an antenna
2,33 may cause induced voltage. This induced voltage is an alternating current corresponding to the frequency of the transmitted electromagnetic wave, and when the minimum value of the induced voltage is lower than the set voltage of the Schmitt inverter 31, the Schmitt inverter 31 inputs L And outputs an H output, that is, an error signal equivalent to the ball detection signal to the CPU.

In other words, the CPU gives the player an unreasonable profit by opening the special winning opening based on the erroneous signal. In other words, the game store suffers serious damage.
In addition, the electromagnetic wave that may cause a malfunction in the gaming machine is not always transmitted intentionally, and may be transmitted from a car equipped with a wireless communication device (illegal) that generates a strong electromagnetic wave from outside the game store. Intense electromagnetic waves may cause the gaming machine in the store to malfunction, and such a malfunction of the gaming machine is not always advantageous to the player, and may cause a malfunction such as terminating the special game that has occurred. When the problem occurs in the gaming machine, the disadvantage to the player becomes extremely large, and there is a possibility that an unnecessary trouble occurs with the gaming shop.

Therefore, regardless of whether intentional or not, when a malfunction-inducing electromagnetic wave that can cause a malfunction of the gaming machine acts on the gaming machine, an effective prevention means that can prevent the malfunctioning of the gaming machine is desired.

In addition, it is desirable that the player can be effectively prevented from being disadvantaged by controlling the gaming machine to prevent malfunction.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and comprises an electrically driven gaming device and a control device for controlling the gaming device (for example, the accessory control device 13). A game machine (for example, a pachinko machine 1 ') connected by wiring and an electromagnetic wave propagating in a game shop where the game machine is installed, and acting on the game machine to cause a malfunction of the game machine. A malfunction-inducing electromagnetic wave detecting means (for example, the electromagnetic wave detecting device 4) for detecting an induced electromagnetic wave, and a game for inactivating a predetermined operation of the gaming machine based on the malfunction-inducing electromagnetic wave detecting means detecting the malfunction-inducing electromagnetic wave. A device operation inactivating means (for example, a control device control device of the management device 10) and a malfunction-inducing electromagnetic wave detection state for notifying that the malfunction-inducing electromagnetic wave detecting means has detected a malfunction-inducing electromagnetic wave. Notification means (e.g., notification means 25), and the gaming machine inoperable clown means is provided with at least a first state disadvantageous to the player and advantageous to the player with the inactivation of the gaming machine. The variable winning device, which is a gaming device convertible to the second state, maintains the first state, and returns the state of the variable winning device based on a predetermined gaming machine deactivation cancellation condition being satisfied. It is characterized by having done.

<Operation> When a malfunction-induced electromagnetic wave that can cause a malfunction of a gaming machine installed in a game store is transmitted, the malfunction-induced electromagnetic wave detection means detects the malfunction-induced electromagnetic wave in the game store,
Based on the detection of the malfunction-induced electromagnetic wave by the malfunction-induced electromagnetic wave detecting means, the gaming machine operation inactivating means inactivates the gaming machine so that the gaming machine cannot perform a predetermined operation. Further, the malfunction-inducing electromagnetic wave notifying unit notifies that the malfunction-inducing electromagnetic wave detecting unit has detected the malfunction-inducing electromagnetic wave. Further, the gaming machine operation inactivating means causes the variable winning device of the gaming machine to maintain the first state with the inactivating of the gaming machine, and thereafter, when a predetermined gaming machine inactivating cancellation condition is satisfied. The gaming machine operation deactivating means returns the variable winning device to the state immediately before the deactivating by restoring the state of the variable winning device in which the first state is maintained in accordance with the deactivating control of the gaming machine. Then, the game is resumed.

<Example> Hereinafter, the present invention will be described in detail based on an example of the drawings.

FIG. 1 is a perspective view of an end of an island facility 1 provided in a game arcade where a large number of gaming machines such as pachinko machines are installed, and FIG. 2 is a schematic system showing the front of the island facility 1 and a control system. FIG. The island facility 1 has a large number of gaming machines (for example, pachinko machines 1 ') arranged in islands, and a game medium and a money supply mechanism and the like are provided inside the island which is invisible to a player. .

The system for preventing malfunction of a gaming machine due to electromagnetic waves according to the present invention malfunctions by acting on a pachinko machine 1 'which is a gaming machine transmitted from a wireless device TX brought into the store by a player or a powerful wireless device outside the store. An electromagnetic wave detecting device 4 having an electromagnetic wave receiving means 2 for receiving an electromagnetic wave (malfunction-inducing electromagnetic wave) which may cause the electromagnetic wave, and a rectifying means 3 for rectifying an alternating current by an induced voltage induced by the electromagnetic wave and converting the alternating current into an electromagnetic wave detection signal Sc It has.

According to the illustrated embodiment, the electromagnetic wave detecting device 4 is provided behind the curtain plate 5 above the island equipment 1 for each pachinko machine 1 ′, and the electromagnetic wave receiving means 2 is formed from the curtain plate 5. Antenna 6 protrudes. The antenna 6 is a so-called loading type compact type in which a conductive wire 8 is wound around a ferrite bar 7, and an induced voltage is induced in the conductive wire 8 by an electromagnetic wave. In the electromagnetic wave detecting device 4 of this embodiment, a high-frequency amplifier circuit 9 is inserted between the electromagnetic wave receiving means 2 and the rectifying means 3 to amplify the electromagnetic waves received by the electromagnetic wave receiving means 2.

As described above, the antenna 6 serving as the receiving unit for receiving the malfunction-induced electromagnetic wave is extended from the outer surface of the island facility 1 and the high-frequency amplifier circuit 9 serving as the amplifying unit for amplifying the received signal received by the antenna 6 is provided. If it is provided, it is possible to detect the malfunction-induced electromagnetic wave satisfactorily. In addition,
The frequency and output level of the malfunction-inducing electromagnetic wave that can cause a malfunction in the gaming machine are determined by the gaming machine (pachinko machine 1 ').
In this case, the electromagnetic wave detection device 4 may malfunction if the frequency band and reception level of the electromagnetic wave to be detected are appropriately determined according to the environment. It can be an electromagnetic wave detecting means.

The high-frequency amplifier 9 is connected to the rectifier 3 constituting the rectifier 3, and rectifies the induced current amplified by the high-frequency amplifier 9 and converts it into a DC electromagnetic wave detection signal Sc. The rectifier circuit 3 is electrically connected to a management device 10 installed in a management room or the like of a pachinko game store, and the electromagnetic wave detection signal Sc is input to the management device 10. In addition, the management device 10 normally supplies the ball to each of the pachinko machines 1 ′, displays the replenishment and stopping of the ball, totals the number of winning balls, totals the number of out-balls, calculates the payout rate, or stops the game. Is managed and controlled.

When the electromagnetic wave detection signal Sc is input to the management device 10 from the electromagnetic wave detection different device 4, the management device 10 performs an illegal process and sends out an illegal signal Sf.

That is, the management device 10 performs the illegal processing M1 based on the electromagnetic wave detection signal Sc, and sends the electromagnetic wave to the pachinko machine 1 '(a gaming machine to which the electromagnetic wave detection device 4 that has transmitted the electromagnetic wave detection signal Sc corresponds). In response, the illegal signal Sf is transmitted to immediately stop the pachinko game. That is, in the present embodiment, the management device 10 functions as a gaming machine operation inactivating means for inactivating a predetermined operation of the gaming machine affected by the malfunction-induced electromagnetic wave.

In addition, the management device 10 outputs an alarm sound to audibly display the fraudulent activity, and visually displays the number of the pachinko machine 1 'in which the fraudulent activity is being performed on the monitor device 11 such as a CRT. That is, in the present embodiment, the management device control device and the monitor device 11 in the management device 10 cooperate,
It functions as a malfunction-inducing electromagnetic wave detection state notifying means for notifying that a malfunction-inducing electromagnetic wave has been detected. If it is confirmed that the malfunction-inducing electromagnetic wave has disappeared, for example, by causing the player who has intentionally sent the malfunction-inducing electromagnetic wave to stop cheating, the reset switch is operated to perform normal management control. Return to normal processing.

For example, a power-off signal that disables the pachinko game by turning off the main power supply 12 that supplies power to each of the pachinko machines 1 ′ as the fraud signal Sf for inactivating the predetermined operation of the pachinko machine 1 ′. The use of So is not desirable because the pachinko machine 1 'cannot be returned to the state immediately before the deactivation.

On the other hand, if the game stop signal St for bringing the accessory control device 13 provided for each pachinko machine 1 'into a game stop state is adopted as the illegal signal Sf, the game stop signal is sent to the accessory control device 13. When St is input, the accessory control device 13 performs an illegal process M2 as shown in the right part of the flowchart of FIG. 4, for example, to temporarily stop the pachinko game.

That is, when the accessory control device 13 receives the game stop signal St which is the fraudulent signal Sf, first, the lamp display device 14 provided on the curtain plate 5 corresponding to each pachinko machine 1 'blinks or lights up, The pachinko machine 1 'in which the action is being performed is visually displayed. Then, it is determined whether or not the pachinko machine 1 'is currently in a special game, and if it is not in a special game, that is, in a normal game, for example, a game such as a variable display of a variable display device 16 provided in the special game device 15 Interrupts the game processing for.

In addition, the movable member of the variable winning device 18 provided on the game board 17
Turn off the solenoid which converts 19 from the first state in which the ball is difficult to flow and the player is disadvantageous to the second state in which the ball is easy to flow and the player is advantageous, to the second state of the variable winning device 18 Block the conversion of In other words, with the occurrence of fraud,
The accessory control device 13 keeps the variable winning device 18 in the first state (forcibly changing the second state to the first state, The game is interrupted).

Further, the blinking display of the display lamp 20 provided on the game board 17 and the output of a cheating alarm sound indicate visually and audibly that the game has been interrupted or that cheating has been performed. As described above, the malfunction-inducing electromagnetic wave detection state notifying means may be provided on the gaming machine side where the malfunction-inducing electromagnetic wave is detected due to the misconduct or the like. In addition, the fluctuation display device
By turning off the decorative lamps, LEDs, and the like provided in 16 and the special game device 15, the blinking of the display lamps 20 and the like are emphasized.

Then, if the source of the electromagnetic wave is eliminated, that is, if the cause of the misconduct has been eliminated, a return process is performed and the game is restarted. Thus, since the game is resumed by returning the variable winning device 18 to the state immediately before the deactivation of the pachinko machine 1 ', during the game in which the variable winning device 18 is changed to the second state. Even when the malfunction-induced electromagnetic wave not involving the player playing the game with the pachinko machine 1 'is detected and the deactivation control is performed by the accessory control device 13, the deactivation is canceled. In this case, since the variable winning device returns to the state immediately before the deactivation, the disadvantage to the player can be suppressed.

During the special game, that is, when the variable winning device 18 is in the second state advantageous to the player, when the electromagnetic wave is transmitted and the game stop signal St is input to the accessory control device 13, the above-described normal game is performed. The game is interrupted as in the case of.

However, the timing of the return processing for restarting the game is slightly different. That is, if the special game is suddenly resumed, there is a possibility that a player who does not prepare for launching the ball or the like may not be able to enjoy the benefits related to the special game, so a grace period of 20 seconds is given as a wait time, for example. The wait time is subtracted and displayed to draw the player's attention, and a return process is performed after the above-mentioned wait time has elapsed.

Further, by providing the above-mentioned wait time, when a large amount of winning balls are generated by the special game and the ball is clogged by the prize ball discharging device or the like, the clogged ball can be removed. It is to be noted that the special item control device 13 indicates that a special game is being played, and that a visible display device 21 described later provided above the island facility 1.
, A special game display signal Sd is output to the visible display device 21.

Further, as shown by the broken line in FIG. 3, a firing stop signal Sh acting on the firing control device 22 for firing one ball provided in each pachinko machine 1 'may be output as the illegal signal Sf. . If the firing control device 22 is not activated, the ball is not fired, so that the player is not unduly disadvantaged.

On the other hand, above the island facility 1, there is provided a visible display device 21 composed of, for example, three-stage lamps, the lighting of which is controlled by the visible display control device 23. The first line L1 at the upper stage of the visual display device 21 normally flashes when the player operates the call switch 24 to call a clerk of the pachinko parlor when a ball is clogged or the like. The second lamp L2 in the middle stage blinks based on the electromagnetic wave detection signal Sc when the above-mentioned malfunction-induced electromagnetic wave is detected, and constitutes a notifying means 25 for visually displaying the generation of the electromagnetic wave relating to the misconduct. The lower third lamp L3 blinks based on the special game display signal Sd when a special game has occurred in any of the pachinko machines 1 'of the island facility 1.

The monitoring device 11 of the management device 10 and the island equipment 1
The lamp display device 14, the display lamp 20 of the pachinko machine 1 ', and the like also constitute a notifying means 25 for visually displaying an illegal act.
Alternatively, a fraudulent alarm sound or the like emitted by the accessory control device 13 also constitutes the sound informing means 25. In the embodiment of FIG. 3, the electromagnetic wave detection signal Sc is directly transmitted to the visible display control device.
Although input is made to 23, it may be input via the management device 10.

And, as shown in the illustrated embodiment, when the electromagnetic wave detecting device 4 is installed corresponding to each pachinko machine 1 ', the electromagnetic wave detecting device 4 closest to the source of the electromagnetic wave responds, so that the malfunction induced electromagnetic wave The pachinko machine 1 'which is most susceptible to the above can be easily specified.

In this embodiment, the detection sensitivity is increased by projecting the antenna 6 from the front of the curtain plate 5, but the antenna 6 may be housed inside the curtain plate 5 so that the player does not mischief. Also, the electromagnetic wave detecting device 4 is not provided corresponding to each pachinko machine 1 ', but one electromagnetic wave detecting device 4 is provided corresponding to the island facility 1 (for example, for six pachinko machines 1'...). They may be provided, or may be arranged at appropriate intervals on a ceiling or the like. The electromagnetic wave detection device 4 is not affected when the pachinko machine 1 'is replaced, even when the electromagnetic wave detection device 4 is provided on the curtain plate 5 as well as when it is provided on the island equipment 1 or the ceiling. , Which can be used as permanent equipment of pachinko amusement arcades and has a high economic effect.

The electromagnetic wave detection device 4 is not limited to malfunction-induced electromagnetic waves transmitted from a wireless communication device such as the wireless device TX, and may be malfunction-induced electromagnetic waves generated as noise from an electronic writer or the like.
Works effectively.

<Effects of the Invention> In summary, according to the present invention, when a malfunction-inducing electromagnetic wave that can cause a malfunction of a gaming machine installed in a game store is transmitted, the malfunction-induced electromagnetic wave is detected in the game store by a malfunction-inducing electromagnetic wave detecting means. Is detected, based on the malfunction-inducing electromagnetic wave detecting means detecting the malfunction-inducing electromagnetic wave,
Since the gaming machine operation inactivating means inactivates the gaming machine so that a predetermined operation cannot be performed, an erroneous operation of the gaming machine gives an unfair gaming profit to the player and The loss can be prevented from being increased, and the player can be prevented from being disadvantaged.

In addition, when the malfunction-inducing electromagnetic wave detecting means detects the malfunction-inducing electromagnetic wave, the state is notified by the malfunction-inducing electromagnetic wave notifying means, so that the clerk of the game store or the like performs the processing for the inactivated gaming machine. It can be performed quickly, and the source of the malfunction-induced electromagnetic wave can be easily identified.

Further, the gaming machine operation inactivating means causes the variable winning device of the gaming machine to maintain the first state with the inactivating of the gaming machine, and thereafter, when a predetermined gaming machine inactivating cancellation condition is satisfied.
