Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention, when the detection circuit for detecting the number of winnings to the special winning opening when the special winning opening is open, or when the detection circuit is modified The present invention relates to a pachinko gaming machine capable of detecting a failure or fraud while performing fraud.

[Technical background of the invention and its problems]

The pachinko gaming machine has a plurality of winning holes on the surface of the game board, and when a pachinko ball hit by the player along the board wins the winning holes, a certain number of prize balls are paid back. In this pachinko gaming machine, when a pachinko ball wins a specific winning hole, the numerical display by LED and the display by a rotating drum are variably displayed, and after a certain period of time or by the player operating a stop switch. ,
The variable display of the display unit is stopped, and the display state when the display is stopped is a predetermined display state (for example, 7/7/7).
When it becomes, open the special winning opening for a certain time,
It is well known that there are various things that significantly increase the winning rate of pachinko balls.

By the way, according to the Customs Business Control Law, when the number of pachinko balls to the special winning opening exceeds a certain number, the special winning opening is automatically closed even within the open time of the special winning opening. As a pachinko ball is stipulated not to enter into the big winning opening without restriction.

However, in the conventional pachinko game machine, if the circuit that detects the winning of the pachinko ball to the special winning opening fails for some reason, the number of winnings of the pachinko ball to the large winning opening exceeds a certain number specified by the law. Even so, there was a drawback that the special winning opening would not be closed. In addition, in the conventional pachinko gaming machine, the manager of the game hall has modified the circuit that detects the winning of the pachinko ball to the special winning opening so that the number of winnings of the pachinko ball to the large winning opening is above the predetermined number. Even if it becomes, there was a drawback that the pachinko gaming machine could be modified so that the special winning opening would not be closed, and fraud could be easily performed. In order to eliminate such defects, when the winning of the pachinko ball to the special winning opening cannot be detected for a certain period of time despite the fact that the special winning opening is open, an alarm is issued as if there was the malfunction or fraud. , A pachinko game machine in which the special winning opening is forcibly closed has been devised (JP-A-60-31779).

However, in such a pachinko gaming machine, not only in the case of the failure or fraud, but also in the case of the failure or fraud even when the player is not actually firing a pachinko ball when the special winning opening is open. Similarly, there was a drawback that an alarm was issued and the special winning opening was forcibly closed. That is, the pachinko gaming machine has a drawback that it is impossible to distinguish between a normal state and an abnormal state.

[Object of the Invention]

The present invention has been made based on the above circumstances, and provides a pachinko gaming machine capable of accurately detecting a failure or fraud in a detection circuit that detects the number of winning balls to the special winning opening in the open state. That is the purpose.

[Outline of Invention]

The outline of the present invention for achieving the above object is that when a particular game state is reached, the special winning opening is opened, and after a certain period of time or when a certain number of pachinko balls are won in the special winning opening, the big winning opening is In a closed pachinko gaming machine, when the special winning opening is open, and the launching device that launches the pachinko ball is operating, but the winning of the pachinko ball into the special winning opening is not detected for a certain period of time. The first is to give an alarm.

Example of Invention

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a front view of a pachinko gaming machine which is an embodiment of the present invention. In the figure, reference numeral 1 is a pachinko game machine, and a game board surface 3 surrounded by a guide rail 2 is provided with 7-segment type numerical indicators 4a to 4d, a big winning opening 5 and various winning holes 6a to 6f. In addition, an out hole 7 is provided for collecting the non-winning pachinko balls. Among the prize holes 6a to 6f, 6a, 6b, 6c are special prize holes provided with a prize ball sensor not shown, and when a pachinko ball wins here, the numerical indicators 4a, 4b, 4c convert random numbers. indicate. V inside the special winning opening 5
The winning hole 5a allows winning of a pachinko ball only when the open / close door 5b is opened by a solenoid (not shown). Further, on the game board surface 3, a V lamp 9 indicating that the opening / closing door 5b is in an open state and a windmill 10 for restricting winning in the winning holes 6a to 6f are arranged. In addition, 7a is an out ball detection switch for detecting an out ball, 11 is the numerical display
A stop switch that stops the conversion display of 4a, 4b, 4c, 12 is an instruction switch that instructs the display of the integrated value of the number of pachinko balls won in the special winning hole, 13 is a built-in firing switch that emits a pachinko ball firing signal At the same time, a launch handle for adjusting the strength of the hit ball, 13a is a finger rest portion of the launch handle 13, 14 is a speaker, 15 is a hammer, and 15a is a hammer detection switch for detecting the motion of the hammer.

The player operates the firing handle 13 to hit a pachinko ball. Then, the pachinko ball that was launched is the guide rail 2
Flows into the game board surface 3 along and falls along the game board surface 3. The dropped pachinko balls enter either of the winning holes or are collected in the out holes 7. In the process, one with a pachinko ball wins one of the special winning holes 6a, 6b, 6c. Then, a detection signal is emitted from the winning ball sensor, and the numerical indicators 4a, 4b, 4c start conversion display. After a lapse of a certain period of time or when the player presses the stop switch 11, the conversion display is stopped and the numerical indicators 4a, 4b, 4c display three-digit numbers. If the three-digit number indicates, for example, 7/7/7, the CPU 21, which will be described later, judges the display state and issues a signal, and turns on the V lamp 9 to produce a sound effect from the speaker 14. The open / close door 5b of the special winning opening 5 is kept open for 30 seconds or until 10 of the pachinko balls are won in the special winning opening 5. This winning number is displayed on the numerical display 4d.

Now, it is assumed that the detection circuit that detects that 5 to 10 large-scale winning holes of the pachinko balls have failed. Then, a signal indicating that the special winning opening 5 is open, a signal indicating that the number of winnings in the open special winning opening 5 is not detected even after a certain period of time, and a pachinko ball launching device is activated. A signal indicating that you are doing is issued, an alarm is issued, and the special winning opening 5
Close the open / close door 5a. In this case, the special winning opening 5 is in an open state, and even if the winning of the pachinko ball into the special winning opening 5 is not detected after a certain time has passed, if the pachinko ball launching device is not operating. , The alarm is issued and the opening / closing door 5a of the special winning opening 5 is not closed. In other words, even if the special winning opening 5 is in the open state, if the player has not fired a pachinko ball, it will not give an alarm or close the opening / closing door 5a of the special winning opening 5. In addition, when the manager of the amusement park has modified the detection circuit that detects that 10 pachinko balls have won, and made the detection circuit inoperable, for example, short-circuit the normally closed contact of the detection circuit. The same applies when the normally open contact is released or the detection switch is shifted.

FIG. 2 is a block diagram of a control circuit of the pachinko gaming machine of this embodiment. In FIG. 2, 21 is a CPU, 22 is a flip-flop, 23 is a driver, and 24 is a solenoid for opening and closing the opening / closing door 5a of the special winning opening 5. Further, 25 is a detection switch for detecting the number of balls won in the special winning opening 5, 26 is a pulse circuit, 27 is a counter, 28 is a timer, and 29 is a normally closed type detection switch. Reference numeral 30 is a judgment circuit for judging that the pachinko ball has not been fired, a firing detection circuit for detecting that the pachinko ball firing device is operating, and 31 is an alarm means. Note that R is a resistor, G ₁ is an OR gate, and G ₂ is an AND gate.

As mentioned above, when the pachinko ball wins the special winning holes 6a, 6b, 6c and the numerical display 4a, 4b, 4c displays 7/7, and stops, the CPU21 judges this display state. Signal to flip-flop 22. Flip-flop 22 is set by this signal and its output signal is the driver
23, the solenoid 24 operates and the special winning opening 5 is opened. Further, when the flip-flop 22 is set, the timer 28 operates, and after a certain time elapses, the gate G ₁
Send a signal to. Since the gate G ₁ is a logical sum gate, when the signal from the timer 28 is received, the output signal is sent to the flip-flop 22 and the flip-flop 22 is reset. As a result, no signal is sent to the driver 23, so the solenoid 24 returns to its original state and the special winning opening 5 is closed.

In addition, when a pachinko ball wins the big winning opening 5 in the open state,
The detection switch 25 is opened, and the voltage reduced by the resistor R is applied to the pulsing circuit 26 as a signal. This signal is shaped by the pulsing circuit 26 and then sent to the counter 27. The counter 27 sends a count-up signal to the gate G ₁ when the number of input pulses reaches 10. The gate G ₁ receives this signal and resets the flip-flop 22 as described above. As a result, the driver 23 returns the solenoid 24 to the original position and closes the special winning opening 5.

Further, when the contact of the detection switch 25 remains closed for some reason, the judgment circuit 29 operates and sends a signal to the gate G ₂ when the time in the closed state exceeds a preset predetermined time. . However, since the gate G ₂ is a logical product gate, in addition to the signal from the decision circuit 29, the CPU 2
If the signal from 1 for opening the special winning opening 5 and the output signal from the firing detection circuit 30 for detecting the firing state of the pachinko ball are not input, the gate output signal is an alarm means.
I will not send it to 31. That is, the gate G ₂ is connected to the decision circuit 29.
From the CPU 21, the signal for opening the special winning opening 5 from the CPU 21, and the output signal from the firing detection circuit 30 are simultaneously input, the gate output signal is output to the alarm means 31 and the gate.
Send to G ₁ . As a result, the flip-flop 22 is reset and the special winning opening 5 is closed as described above.

FIG. 3 is a detailed block diagram of the firing detection circuit. 40 is 2
It is a light receiving element which is arranged in proximity to the launch trajectory of a pachinko ball guided by two guide rails 2. The four light-receiving elements 40 are such that the next pachinko ball passes through the light-receiving element 40 until one pachinko ball finishes passing through the four light-receiving elements 40, even when the pachinko balls are continuously fired. Are arranged at appropriate intervals so that there is no Reference numeral 41 is a pulsing circuit that shapes the signal from the light receiving element 40. Reference numeral 42 is a multitude circuit that outputs an output signal when the number of input pulses is two or more. Reference numeral 43 is a watchdog timer which issues a time-up signal when the next signal is not input within a preset time and resets the set time when the next signal is input within that time.

First, when the pachinko ball is not fired, the light receiving element
Since the light of the illumination lamp in the game shop is incident on 40, the intermittent signal is not emitted. Next, when a pachinko ball is launched and passes through the launch trajectory, the light receiving element 40 placed on the launch trajectory is blocked from entering the light from the illumination lamp in the game store, and the light receiving element 40 is moved to the pulse circuit 41. Send a signal. The multiple circuit 42 is
When there are two or more signals from the light receiving element 40, the output signal is sent to the watchdog timer 43. Therefore, when the pachinko ball is being fired, the output signal of the multiplication circuit 42 is sent to the watchdog timer 43 within the preset time-up time.
Timer 43 is reset and does not signal gate G ₂ . However, when the pachinko ball is not fired, the output signal of the multiplication circuit 42 is not sent to the watchdog timer 43 within the preset time-up time, so the watchdog timer 43 is not reset and after a certain time. , Issues a time-up signal to gate G ₂ .

The gate G ₂ is sent a signal from the CPU 21 when the special winning opening 5 is opened, a signal is sent from the judgment circuit 30, and a time-up signal of the watchdog timer 43 is sent. Only when there is no (that is, when the pachinko ball is being fired), the output signal is output as a warning means.
31 and the reset terminal of the flip prop 22. As a result, an alarm is issued and the special winning opening 5 is closed.

According to the above-mentioned present embodiment, even if the judgment circuit detects that there is no winning of the pachinko ball to the special winning opening in the open state, a signal for detecting that the pachinko ball is being fired should be input. For example, an alarm is issued and the special winning opening is never closed. That is, according to the present embodiment, even though the pachinko ball is being shot by the player, due to a failure or fraud, when the circuit for detecting the winning of the pachinko ball to the special winning opening in the open state does not operate, Although an alarm is issued, the alarm is not issued when the circuit for detecting the winning of the pachinko ball to the special winning opening in the open state does not operate because the player has not fired the pachinko ball. Therefore, as compared with the conventional pachinko gaming machine, it is possible to more accurately detect the failure or fraud of the circuit that detects the winning of the pachinko ball to the special winning opening in the open state.

Further, according to the present embodiment, since the light receiving element is arranged on the back surface of the game board, even when modifying the conventional pachinko gaming machine, the launching device or the like attached to the machine frame of the pachinko gaming machine. There is an advantage that you only have to replace the game board without modifying.

Although a plurality of light receiving elements are used in the above embodiments, one light receiving element may be used. This makes it possible to detect the failure or fraud with a cheaper and simpler device.

Further, in the above embodiment, only the light receiving element is provided on the game board to detect the emitted pachinko ball, but this emits light to the pachinko ball launch rail portion fixed to the machine frame of the pachinko game machine. Both the element and the light receiving element may be arranged. As a result, it is possible to detect the pachinko ball that is fired more reliably.

Further, in the above embodiment, the light receiving element was used as the means for detecting the emitted pachinko ball, but the present invention is not limited to this, and this is a magnetic sensor or the like which is another electrical detecting means, It may be a mechanical detection means such as a microswitch. It is also possible to arrange these detecting means before the pachinko ball is launched by the launching device.

FIG. 4 is a block diagram showing another specific example of the firing detection circuit. In FIG. 4, reference numerals 30b, 30c and 30d denote launch detection circuits. These launch detection circuits 30b, 30c, 30
d does not directly detect the firing of a pachinko ball, but indirectly detects that the pachinko ball is being fired. SW ₁ is a touch switch provided in the firing handle 13, SW ₂ is a firing switch provided in the firing handle 13, and M is a motor. SW ₃ is a full stop switch, and F is a fuse.

The firing detection circuit 30b consists of the contact 50 of the touch switch SW ₁ . When the player touches the firing switch 13, the contact 50 is turned on and sends a signal to the gate G ₂ . In this case, the touch switch SW ₁ instead of the signal that detects the launch of a pachinko ball.
The signal from is used. The action and effect in this case are almost the same as those in the above case.

The firing detection circuit 30c comprises a reed relay 60. When the player touches the firing handle 13 and the touch switch SW ₁ is turned on and the firing switch SW ₂ is turned on, the electric power is supplied to the motor M and the electric current flows through the motor M. Then, a current also flows through the reed relay 60, the lead is magnetized, and the contact is closed. This causes the signal to gate G ₂
Send to. In this case, instead of the signal for detecting the firing of a pachinko ball, a signal for detecting the state in which the motor is rotating is used. The action and effect in this case are almost the same as those in the above case.

The firing detection circuit 30d includes a rectifier circuit 70, a comparator 71, and a reference battery E. The player touches the firing handle 13, the touch switch SW ₁ is turned on, and the firing switch SW ₂ is turned on.
In this state, power is supplied to the motor M and voltage is applied to the motor M. At the same time, the AC voltage is
It is also supplied to 70, where it is rectified into a DC voltage and then sent to a comparator 71. The comparator 71 compares the sent DC voltage with the voltage of the reference electric field E, and when the DC voltage is higher than the reference voltage, sends an output signal to the gate G ₂ . The comparator 71 is provided to prevent a signal from being sent to the gate G ₂ when the voltage applied to the motor M is such a low voltage that the hammer cannot be operated.
Therefore, in this case, the comparator 71 is omitted and the rectifier circuit
It is also possible to have a circuit in which a transformer is inserted before 70. In this case also, instead of the signal for detecting the firing of a pachinko ball, a signal for detecting the state in which the motor is rotating is used. The action and effect in this case are almost the same as those in the above case.

Although the firing detection circuits 30c and 30d are arranged near the motor M in the above, these firing detection circuits 30c and 30d may be arranged in front of the touch switch SW ₁ or on the back surface of the game board. By arranging the firing detection circuits 30c and 30d on the back side of the game board, even when applied to the conventional pachinko gaming machine, without modifying the launching device fixed to the machine frame of the pachinko gaming machine, the game is played. The advantage is that you only have to replace the board. Further, in the above, the rotation of the motor is electrically detected, but a cam may be provided on the rotation shaft of the motor M and the rotation of the motor M may be directly mechanically detected by using a limit switch or the like.

FIG. 5 is a block diagram showing another specific example of the firing detection circuit. FIG. 5 (a) is a block diagram of the firing detection circuit by out-ball detection, and FIG. 5 (b) is a block of the firing detection circuit by hitting detection. It is a figure. The launch detection circuit for out-ball detection includes an out-ball detection switch 7a arranged in the out hole 7 and a watchdog timer 81. The pachinko ball collected in the out hole 7 is detected by the out ball detection switch 7a, and the signal is sent to the watchdog timer 81. Here, if the signal from the out-ball detection switch 7a is not sent to the watchdog timer 81 within the preset time, the watchdog timer is not reset, the watchdog timer 81 times up, and the signal is output to the gate G Send to ₂ .
This is to use the signal for detecting the out ball instead of the signal for detecting the pachinko ball, because the pachinko ball must be fired whenever the out ball is detected. The place where the out-ball detection switch 7a is arranged is not limited to the back surface of the game board, and may be the machine frame portion of the pachinko gaming machine. The action and effect in this case are almost the same as those in the above case.

The launch detection circuit for hitting a ball is composed of a ball hammer motion detection switch 15a for detecting the motion of the ball hammer 15 and a watchdog timer 82. Operate the firing handle 13 to drive the motor M
When is rotated, the batting mallet 15 hits a pachinko ball. The movement of the batting mallet 15 at this time is detected by the batting mallet movement detection switch 15a using a limit switch or the like, and the output signal thereof is sent to the watchdog timer 82. Here, if the signal from the batting mallet movement detection switch 15a is not sent to the watchdog timer 82 within a preset time, the watchdog timer 82 is not reset and the watchdog timer 82 times out after the set time has elapsed. Gate signal
Send to G ₂ . This is when the pachinko ball is firing,
Since the batting mallet 15 should be operating, a signal for detecting the motion of the batting mallet 15 is used instead of the signal for detecting the firing of the pachinko ball. The action and effect in this case are almost the same as those in the above case.

In the above-mentioned embodiment, the warning is issued and the special winning opening is opened. However, the present invention is not limited to this, and instead of opening the special winning opening, the special winning opening is used. It may be impossible.

Further, in the above-described embodiment, the first-class continuous role type (throttle type) pachinko gaming machine has been described, but the present invention is not limited to this, and other second-class continuous role type pachinko gaming machines. It may be a machine or the like.

Further, in the above-mentioned embodiment, the pachinko gaming machine having the big winning opening has been described, but the present invention is not limited to this and may be a pachinko gaming machine having another variable winning opening.

Further, in the above-described embodiment, the motor is used as the drive unit of the pachinko ball launching device, but the present invention is not limited to this, and other electrical means such as a rotary solenoid may be used. Good.

〔The invention's effect〕

As described above, according to the present invention, the failure or fraud of the detection circuit that detects the number of winning balls to the special winning opening in the open state, by detecting in association with the operating state of the pachinko ball launching device, A pachinko game machine that can be accurately detected can be provided.
