Abstract

PURPOSE:To enable an unfair game to be prevented from being played by measuring the pulse width of output signal transmitted from a detector, and by recognizing the pulse width to be of normal prize-winning signal when the pulse width is within a specified range, to recognize the pulse width to be of unfair signal or noise when the pulse width is out of the specified range. CONSTITUTION:Detectors 11a, 11b for detecting balls run into specific prize- winning ports 7a, 7b and transmitting output signal, and a detector 13 for transmitting output signal for enabling the second state of a fluctuating prize-winning device 4 to continue, are arranged at least. In this case, when the pulse widths of the output signals from the respective detectors are within a specified range, then the pulse widths are recognized to be of normal prize-winning signals, and when the pulse widths of the output signals are out of the specified range, then an electric controller 10 for recogning the pulse widths to be of unfair signals or noises is set. As a result, without arranging a special sensor and an unfair-game-proof device, unfair games can be previously prevented from being played.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a variation that can be converted from a first state disadvantageous to the player to a second state advantageous to the player by the establishment of a predetermined condition such as winning a prize with a batted ball. The present invention relates to a pachinko machine having a prize-winning device, and particularly to a pachinko machine that prevents illegal games by using a difference in pulse width of an output signal sent by a detector.

<Conventional technology> Recently, in addition to receiving and receiving the batted ball flowing down the game board surface,
A specific winning hole equipped with a detector that detects this hit ball and sends out an output signal, and a variable winning device that can convert from a first state disadvantageous to the player to a second state advantageous to the player when a predetermined condition is met. Pachinko machines equipped with
Many pachinko machines of this type have been proposed.

<Problems to be Solved by the Invention> However, the detectors in conventional pachinko machines have insufficient measures against fraudulent games. For example, by sending electromagnetic waves using a radio or electronic ignition device to cause a detector to malfunction, or by inserting a wire or the like through a gap in the glass to activate a detector, players may There are people who fraudulently win prize balls by converting them to right-handed second-hand 7-1 balls. Therefore, countermeasures such as eliminating gaps in the glass to make it impossible to insert metal objects, and shielding to avoid being affected by electromagnetic waves have been implemented, but they are not universally effective against different forms of fraud. No effective countermeasures have yet been proposed.

As a result of extensive research, the inventor of the present invention discovered that the output signal of a detector related to fraudulent activity has a longer pulse width than that of a regular output signal, leading to the present invention.

Means for Solving the Problems> The present invention has been proposed in view of the above, and provides a special prize 1 in which a player can win a prize by hitting 911 balls in the game area on the surface of the game board surrounded by guide rails. -1, and a variable winning device capable of converting between a first state disadvantageous to the player and a second state advantageous to the player; a second detector of the variable winning device;
and a detector that sends out an output signal that can continue the state, and electrical control that recognizes the output signal from the reporter detector as a regular winning signal when the pulse width is within a predetermined range. It is equipped with a device.

<Function> The present invention uses the configuration described in "-" to measure the pulse width of the output signal sent out by the detector, recognize the pulse width within a predetermined range as a regular winning signal, and detect signals outside the range. If the signal deviates from the above, it is recognized as a false signal or noise.

<Example> Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

The present invention focuses on the fact that the pulse width of the output signal of the detector due to fraudulent activity is longer than the pulse width of the output signal sent out by properly detecting a ball, Only when the pulse width is within a predetermined range is recognized as a regular detection signal, and winning processing is performed.

That is, in the case of a contact type detector using, for example, a microswitch, the pulse width of the output signal sent out when one ball is detected is in the range of 7 to 25 msec, according to experiments. Also,
In the case of a non-contact type detector using a proximity switch, a first sensor, etc., the pulse width of the jlj force signal falls within the range of 5 to 11 msec.

On the other hand, when activating a detector by transmitting electromagnetic waves from a radio, etc., no matter how quickly the player operates the transmission switch, the pulse width of the output signal sent out by the detector in response to the electromagnetic waves is 50. ~ Loom seconds, and under normal operation it will take more than 1 second. Further, when the detector is operated using a foreign object such as a wire, the pulse width of the output signal is generally several seconds.

On the other hand, the detector may send out an output signal with an extremely short pulse width due to external noise such as static electricity, and conventional electrical control devices also malfunction due to the output signal due to the external noise. Experimentally, the pulse width of the output signal caused by external noise is 0.4 msec or less.

Therefore, the present invention recognizes a case where the pulse width of the output signal of the detector 11j is in the range of 0, 4 to 30 msec as indicated by -1- to be a regular winning signal, and performs winning processing. The setting is such that an output signal that deviates from the width is recognized as a fraudulent signal or noise and is processed.

Next, individual cases will be explained along with the game in the pachinko machine 1 as shown in FIG.

In the pachinko machine 1, a variable winning device 4 is disposed approximately in the center of a gaming section 3 surrounded by a guide rail 2, and a player can handle the ball firing device 5 at the lower part of the variable winning device 4. Three special winning lowers are provided in the horizontal direction, where the ball hit by operating 6 can win a prize. ” 1. The variable winning device 4 has a movable member 8 on the side edge of the big prize opening 9 that is rotated by excitation of a solenoid as a driving source, and when the movable portion side 8 is upright, the variable winning device 4 does not move The hit ball cannot flow into the big prize opening 9, resulting in a first state disadvantageous to the player. On the other hand, when the drive source is driven and the movable part side 8 is rotated outward, the big prize opening 9 opens and the ball that flows down the gaming part 3 is very likely to flow into the big prize opening 9, which is advantageous for the player. The second state is reached. Then, by the control processing of the electric control device 10 which will be described later, this variable winning device 4 controls the first specific winning hole 7a when the ball wins in the central first specific winning hole 7a.
(Accordingly, the movable member 8 is 0.8
It opens and closes twice per second, and when a prize is won in the second specific winning lower b located on both sides, it opens once for 0.5 seconds based on the detection output of the t52 specific winning prize detector 11b. And, while the big winning hole 9 is open, the ball that flows into the big winning hole 9,
Furthermore, when a prize is won in the continuation prize opening 12 provided in the variable prize winning device 4, the movable part invitation 8 is pressed with cotton for 0.8 seconds based on the detection signal of the continuation prize detector 13 placed facing the continuation prize opening 12. One cycle is defined as opening and closing 18 times, and it can be updated up to a maximum of 8 cycles. Incidentally, when 10 batted balls enter the big winning prize 119 during the above l cycle, the cycle ends.

The electrical control device 10 that performs the above-mentioned control processing has a microcomputer configuration, for example, and includes a timer 14. In a normal processing state, that is, in a state where there is no output signal from each detector 11.13, the electric control device 10 performs normal control processing because the timer value is "0". - On the other hand, when receiving some output signal from each detector 11.13, the timer 14 is reset, and while the output signal from each detector 11.13 continues, the corresponding timer 14 is activated. Count up.

When the output signals from each detector 11 and 13 stop, the count value of the timer 14 is determined, and if the count value is within the predetermined range of 0°4 to 30 msec, it is normal. It determines that it is a winning signal and performs game processing.

This game process is performed by, for example, the first specific winning detector 11a.
detects a batted ball and sends out an output signal, and if the pulse width of this output signal is 28 msec, the electrical control device 10 sends a drive control signal to the drive source to cause the solenoid to run for 0.8 seconds. The movable member 8 is energized twice and opened twice with cotton for 0.8 seconds.

In J, which is issued from a tree, if the value of the timer 14 is greater than 30 msec, it is recognized as a fraudulent signal, and the fraudulent signal is sent to perform fraudulent processing. For example, when a player operates a wireless device to transmit radio waves, the continuous winning of variable winning device 4 [:l
If the continuation prize detector 13 placed in front of 12 reacts and sends out the lJi force signal, and the pulse width of this output signal is 60 msec, the electrical control device 10 will not send out the drive control signal. For example, there is an accessory control device (forming part of the electrical control device 10) provided in each famous pachinko machine 1.
A game stop signal that puts the game in a game stop state is sent as a fraudulent signal. When a game stop signal is input to the accessory control device,
This accessory control device temporarily stops the pachinko game by performing fraudulent processing as shown in the flowchart of FIG. 5, for example. That is, when the accessory control device receives the game stop signal, which is an illegal signal, it first determines whether the pachinko machine 1 is currently playing a special game, and interrupts the game processing regarding the pachinko game. In addition, the movable part 8 of the variable prize winning device 4 disposed in the gaming section 3 is driven to convert from a first state where it is difficult for batted balls to flow in and the player is disadvantageous to a second state where the ball is easy to flow in and the player is advantageous. This solenoid is turned off to prevent the variable prize winning device 4 from converting to the second state. Further, by blinking the display lamp 15 provided on the game board and outputting a fraud alarm sound, it is visually and audibly indicated that the game is being interrupted or a fraudulent act is being committed. In addition, other decorative lamps 16, LEDs, etc. provided on the pachinko machine 1 are turned off to make the blinking of the display lamp 15, etc. written "-" stand out. Then, once the cause of the fraudulent act has been removed, recovery processing is performed and the game is restarted.

On the other hand, if the game stop signal is input to the accessory control device during the special game, that is, when the variable prize winning device 4 is in the second state advantageous to the player, the game will be processed in the same way as in the case of the normal game described above. is interrupted, the solenoid of the variable prize winning device 4 is turned off, the display lamp 15 is dimmed, a fraud alarm sound is output, and other decorative lamps 16, LEDs, etc. are turned off. but,
The timing of the return process to restart the game is slightly different.

In other words, if the special game is restarted suddenly, there is a risk that players who have not prepared to launch the ball will not be able to enjoy the benefits of the special game, so a wait timer of, for example, 20 seconds is set and the wait time is A grace period of 20 seconds is given, and the elapsed wait time is subtracted and displayed to call the player's attention, and the return process is performed after the wait time has expired. In addition, by providing the above-mentioned wait time, in the event that a special game results in a prize ball of ``Oji'' and the ball becomes clogged in the prize ball ejector (not shown), etc., the clogged ball can be removed. If the cause of the fraudulent activity is removed, recovery processing is performed and the game is restarted.

Note that the wait timer is reset at the time of this return.

Incidentally, as the illegal processing, the ball firing device 5 may be stopped so that the ball cannot be fired other than the above-mentioned method, or other means may be used to prevent illegal games.

Further, in the present invention, the count value of the timer 14 is 0.4 m.
Since a pulse width of 0.3 m or less is regarded as noise, the first specific winning detector 11a detects a pulse width of 0.3 m as shown in Fig. 4.
Even after sending out the second output signal, the electrical control device 10 continues normal processing.

Next, when the second specific winning detector 11b sends out an 8 msec output signal, the electrical control device 10 recognizes it as a regular detection signal, sends out a drive control signal, and turns the solenoid to 0.
．． Excite for 5 seconds and open the big prize opening 9 for 0.5 seconds.

Furthermore, when the player inserts a foreign object such as a wire and activates the second specific winning detector 11b of the second specific winning lower b, the second specific winning detector 11b sends out an output signal.
Since the pulse width of this output signal is as long as one second, the electrical control device 10 identifies it as fraudulent, sends out a fraudulent signal, and performs the fraudulent processing described above.

Then, when the continuous winning detector 13 sends out a 15 msec output signal, the electrical control device 1o recognizes it as a regular detection signal, sends out a drive control signal, and excites the solenoid 18 times at 0.8 second intervals. to open and close the big prize opening 9.

In the embodiment shown in the drawings, when a ball hits the specific winning lower, the movable member 8 of the variable winning device 4 opens and closes once or twice, and the ball that flows into the variable winning device 4 continues to win D.
12, the pachinko machine 1 opens the variable winning device 4 a predetermined number of times when a prize is won, but when a ball hits a specific winning hole, the variable display device starts displaying a variable prize.
Depending on the display mode when the variable display device stops, if the variable winning device is a pachinko machine that is open for 30 seconds, or if a ball hits a specific winning device and it is in the right state, the variable winning device may be set to 1 for a predetermined winning. It may be a pachinko machine that opens the grand prize opening for, for example, 10 seconds when a hit ball wins a prize.

The present invention also provides specific winning lower prizes for each pachinko machine.
Not only can it be applied to the detector 11.13 facing the continuous winning opening 12 of the variable winning device 4, but also a 10 count detector that counts the batted balls flowing into the variable winning device 4 and other winnings [= It may be applied to one detector.

<Effects of the Invention> In summary, the pachinko machine according to the present invention includes a detector that detects a ball that has entered a specific winning opening and sends out an output signal, and an output signal that allows the variable winning device to continue in the second state. If the pulse width of the output signal from each of the above detectors is within a predetermined range, it is recognized as a regular winning signal, and the pulse width of the output signal deviates from the predetermined range. Since we have installed an electrical control device that recognizes the signal as a false signal or noise when the game is being played, it is possible to prevent fraudulent gaming without installing special sensors or equipment to prevent fraudulent gaming, reducing losses for pachinko parlors. To prevent this and also to enable a healthy pachinko game. Furthermore, the present invention can be applied not only to contact type detectors and non-contact type detectors, but also to cases in which the detector is directly operated using side fittings, etc., and wireless It also functions effectively even when devices are caused to malfunction by electromagnetic waves, so it has extremely high practical value as it is effective against various types of fraudulent acts.
