Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a first state in which a movable wing piece is substantially upright and a hit ball flowing down a game board enters only from above, and the first state.
When the hit ball enters in the state, the movable wing piece tilts in the lateral direction and can be converted into the second state in which the hit ball can enter from the upper direction and the lateral direction. The present invention relates to a winning device for a pachinko machine, in which an output is generated from a switch mechanism to obtain winning information, and another device is operated according to this winning information.

<Prior art> Two movable wing pieces facing each other are substantially upright, and a first state in which a hit ball enters only from above, and when a hit ball enters from above in this first state, both movable wing pieces move laterally. A winning device for a pachinko machine that tilts to a second state and is converted into a second state in which a hit ball can be entered from the side has been conventionally known. Further, a prize winning device in which a switch is provided in the prize winning device to turn on a lamp and the like is also known from Japanese Utility Model Publication No. 60-37372.

In the conventional prize winning device described above, the movable wing piece is changed from the first state to the second state.
When converted to the state, the switch mechanism that has been in the off state becomes the on state, and as long as the second state continues, the switch mechanism remains in the on state and the decorative lamp and the like are lit. Then, when a hit ball enters between the movable blades in the second state and is converted into the first state, the switch mechanism is turned off and the above-mentioned decorative lamp is turned off.

<Problems to be Solved by the Invention> Therefore, in the hit ball winning device having the above-described configuration, the switch mechanism is simply turned on and off depending on the state change of the movable wing piece, and at most, the lighting device such as a lamp is turned on or blinked. However, an output is generated every time a ball is hit in the winning device and cannot be used as winning information for starting another winning device or a gaming device.

<Means for Solving Problems> The present invention has been proposed in view of the above, and a front frame having an open upper surface is provided on the front surface of a mounting substrate fixed to the surface of a game board, and two front frames are provided in the front frame. The movable wing pieces are rotatably supported so as to face each other, and a swinging bottom plate is provided in a guide frame provided on the back surface of the mounting substrate so as to be rotatable in the up-and-down direction. When the ball hits from above in the first state in which both movable wing pieces are substantially upright and the ball can enter only from above, the tip of the rocking bottom plate moves upward due to rolling of the ball. The movable bottom blades are tilted in the lateral direction by the pivotal movement of the swinging bottom plate, and are converted into the second state in which the ball can be hit from above and in the lateral direction. When the ball hits between the movable blades, the weight of the ball hits the movable blades and the tip of the swing bottom plate In a winning device of a pachinko machine that can be swung so as to face downward and converted into a first state, a switch mechanism for turning on and off with respect to each turning motion of the swinging bottom plate is fixedly provided on a guide frame, The output of the switch mechanism is processed to notify the winning device state detection signal for notifying whether the movable wing piece is in the first state or the second state and the first to second states of the movable wing piece.
Switch output processing means for obtaining a pulse signal having the same pulse width as a winning ball detection signal is formed in both the state conversion and the second state to first state conversion, and the winning ball detection signal is used as the winning information. It is characterized in that the other device provided on the game board is operated.

<Examples> Examples of the present invention will be described below with reference to the drawings.

The hitting ball winning device 1 of the present invention has a mounting board 2 to be mounted on the surface of a game board (not shown), and a front frame 3 having an open upper surface is provided on the front surface of the mounting board 2 and the inside of the front frame 3 is provided. The movable wing pieces 5 are pivotally attached to the left and right with the shaft 4 facing each other. Therefore, each movable wing piece 5 is supported so as to be rotatable about the shaft 4 between an upright state and a state of tilting laterally outward.

A through hole 6 for hitting a ball is formed in the above-mentioned mounting board 2, and a guide frame 7 for hitting a ball is extended to the rear surface, and a guide shaft 7 is supported in the guide frame 7 by a support shaft 8 so as to be vertically movable. Then, the tip portion 10 of the guide bottom plate 9 is exposed from the passage hole 6 into the facing space between the movable blade pieces 5. If the guide bottom plate 9 is in a substantially horizontal state in the guide frame 7, since the tip portion 10 is located below the facing interval between the movable wing pieces 5, both the movable wing pieces 5 are substantially upright and hit only from above. Is in the 1st state where does not enter. When a hitting ball enters between the movable wing pieces 5 from above in the first state, the hitting ball is placed on the swinging bottom plate 9 and rolls in the guide frame 7, and when passing the support shaft 8, the guide bottom plate 9 is moved by its own weight. The tip 10 is swung so as to face upward. When the guide bottom plate 9 pivots as described above, both movable wing pieces 5 tilt laterally toward the outside by the tip portion 10, so that the winning device 1 can also hit a ball from the lateral direction. Convert to state.

When a hit ball is placed on the movable wing piece 5 which is tilted in this second state, both movable wing pieces 5 rotate so as to return to the upright state due to the weight of the hit ball, and the guide bottom plate 9 also supports the support shaft 8 as a fulcrum. The first state in which the ball does not easily enter the ball is swung horizontally.

In the winning device 1 configured as described above, the cut portion 11 is formed in the upper half of the rear portion of the guide frame 7, and the fastening portion 12 extending from the left and right back surfaces of the mounting substrate 2 to the cut portion 11 is formed. Form.

The fastening portion 12 described above is solid, and screws can be passed through from the rear end.

A wiring board 13 is mounted behind the guide frame 7. The wiring board 13 is an annular plate made of an insulating plate and provided with an opening 14 through which the guide frame 7 is passed. A wiring portion 15 and a magnetic sensitive switch 16 are provided on the back surface. Then, the wiring board 13
A permanent magnet 17 is provided on the guide bottom plate 9 so as to face the magnetic sensitive switch 16 to be fixed in a state where 14 is passed from the rear end of the guide frame 7 and fixed to the fastening portion 12 with a screw or the like.

The permanent magnet 17 is located on the rear lower surface of the guide bottom plate 9, and when the guide bottom plate 9 pivots upward and both movable wing pieces 5 are in the second state, the magnetic sensitive switch 16 is turned on, and the guide bottom plate 9 is turned on.
Is substantially horizontal and both movable blades 5 are in the first state, the magnetic sensitive switch 16 is off.

Therefore, the magnetic sensitive switch 16 that is substantially attached to and fixed to the guide frame 7 and the permanent magnet 17 that is attached to the guide bottom plate 9 to turn on and off the magnetic sensitive switch 16 constitute a switch mechanism. There is. In the winning device 1 described above, two types of information can be taken out from the magnetic sensitive switch 16.

One of them is a winning device state detection signal S _s that informs the current state of the winning device 1, and the other is that the state of the winning device 1 is changed from the first state to the second state due to winning of a hit ball. It is a winning ball detection signal S _i for detecting a winning ball that has won the winning device 1 regardless of whether it is converted or vice versa.

The winning device state detection signal S _S, for example, continuously has one of the logical levels “H” and “L” when the winning device 1 is in the first state, and is in the second state. In this case, it can be obtained as a signal which continuously emits the other logic level. In addition, the winning ball detection signal S _i is the winning device 1
Can be obtained as a pulse signal or the like that rises to the logic "H" with the same pulse width both when converting from the first state to the second state and when converting from the second state to the first state.

Therefore, in the present invention, the winning device state detection signal S _{S that} is continuously issued according to the state of the winning device 1 is, as described above, a light emitting means or the like that lights up or blinks when the winning device 1 is in the second state, It can be used as information for operating the means to be driven according to the second state of the winning device. And, the winning ball detection signal S _i as another signal form obtained from the magnetic sensitive switch 16 is, for example, another variable winning device or another gaming device (not shown) provided on the surface of the game board. It can be used as a trigger pulse or a starting pulse for starting.

Practically, as an example of the circuit system which constitutes the switch output processing means for obtaining such two kinds of information signals from the switch mechanism, the circuit configuration proposed by the present applicant is shown in FIG. 6, and its operation waveform is shown in FIG. Put as shown in the figure.

If the magnetic sensitive switch 16 is related by the permanent magnet 17 so as to be turned off when the winning device is in the first state and turned on when the winning device is in the second state, the first state of the winning device 1 is an integrating circuit. If it lasts long enough to charge the capacitor 19 in 18 to the power supply potential E _B , the output T _{1 of the} integration circuit 18 concerned
Of course, the power supply potential is E _B.

Here, when a hit ball is won in the winning device 1 and the winning device 1 is converted to the second state, the electro-sensitive switch 16 is inverted from off to on, which eventually causes the discharge of the capacitor 19 in the integrating circuit 18 in the illustrated circuit. It will form a route.

Therefore, the potential across the capacitor 19 starts to decrease according to the time constant with the resistor 20, and eventually reaches almost the ground level.

After this state continues for a while, when the ball hitting the first winning device 1 wins, the winning device 1 changes from the second state to the first state, and accordingly, the magnetically sensitive switch 16 is turned off again. Return to the state.

Then, the capacitor 19 in the integrating circuit 18 passes through the resistor 20,
The current from the power supply begins to be charged with a time constant of the event, eventually both ends potential, namely the potential of the output terminal T ₁ of the integrating circuit 18 returns to the substantially source potential E _B.

Therefore, by monitoring the voltage waveform appearing at the output terminal T ₁ of the integrating circuit 18, it is possible to discriminately know whether the winning device 1 is currently in the first state or the second state.

Upon this, enhance the reliability of the detection, in an easy quality signal waveform processing for subsequent electronic circuit is preferably as shown, in the transition process from the power supply potential E _B to the ground potential First threshold near the ground level
The second threshold value that has E _th1 and is sufficiently higher than the first threshold value in the transition process from almost ground potential to almost power supply potential E _B.
It is _preferable to provide the waveform shaping circuit 21 including a Schmitt trigger circuit having E _th2 .

In this way, when the winning device 1 is converted from the first state to the second state, the output potential of the integrating circuit 18 is the first threshold value E.
_{When it} is less than _th1 , the output logic of the waveform shaping circuit 21 falls from the previous logic “H” to logic “L”, and conversely the second logic.
When the state is converted to the first state, the waveform shaping circuit
The output potential of 21 is a stable signal that returns from the logic "L" to the logic "H" until then, and there is no fear of chattering or the like that tends to occur when the same threshold value is used.

Therefore, first, the output T ₂ of the waveform shaping circuit 21
As shown in the figure, it can be seen that a prize winning device state detection signal S _s having a different logic depending on the state of the winning device 1 is obtained.

This signal is used as it is as an operating signal of various electric elements or electromechanical elements that should be driven according to the second state of the winning device 1, such as a light emitting means that lights up or blinks when the winning device 1 is open. However, in general, we often want a signal that becomes a logical "H" when the prize winning device is open, so in that case, as shown in FIG. The detection signal S _s may be obtained from the terminal T ₄ as a result of inverting the output T ₂ of the waveform shaping circuit 21 by the inverter 22. This signal waveform is the output of the waveform shaping circuit T ₂ shown in FIG. 7 unless significant inverter transit time is taken into consideration.
It is clear that the waveform of
There is no change in the meaning of the information.

On the other hand, in response to the above-mentioned winning device state detection signal S _s , only when the state of the winning device 1 is changed, is it the conversion from the second state to the first state or from the first state to the second state? In order to obtain the winning ball detection signal S _i which is output as a signal having a significant pulse width τ regardless of conversion, the output T ₂ of the waveform shaping circuit 21 is branched in this embodiment, and the exclusive logic It is given to the first input ^# 1 of the sum (Ex.-OR) circuit 23 and the input of the delay circuit 24.

The delay circuit 24 is set with a time constant or delay time according to the pulse width τ to be obtained as the winning ball detection signal S _i ,
The output is given to the second input ^# 2 of the exclusive OR circuit 23.

Therefore, as described above, the winning device 1 converts the first state up to then, into the second state, and accordingly the waveform shaping circuit.
When the output T _{2 of} 21 falls to the logic “L”, both inputs ^# 1 and ^# 2 have been given the same logic “H” until then in the exclusive OR circuit 23. The logic level of the terminal T ₃ is “L”, but at this point, only the first input ^# 1 first falls to the logic “L”, and the delay circuit
Since the second input ^# 2 receiving the output of 24 still maintains the logic “H” for a while, the logical values of both inputs ^# 1 and ^# 2 are different from each other, so that the exclusive OR is applied. The output logic of the circuit 23 is inverted to "H".

However, since the inverted signal from the logic “H” to the logic “L” at the output of the waveform shaping circuit 21 is also given to the delay circuit 24 as described above, it is well shown in the lowermost stage in FIG. As described above, when a predetermined time τ has elapsed, the logical value given to the second input ^# 2 of the exclusive OR circuit as its output is also inverted to the logical “L” like the first input ^# 1, so that After the time point, the logical value of the terminal T ₃ which is the output of the exclusive OR circuit 23 returns to the logical “L” again.

With such a mechanism, as shown in FIG. 7, a pulse signal having a predetermined pulse width τ is first obtained at the terminal T ₃ in accordance with the exchange of the winning device 1 from the first state to the second state. You can see that

However, when a ball is re-winned in the winning device in the second state and the winning device 1 is converted to the first state, the waveform shaping circuit 21 provided to the first input ^# 1 of the exclusive OR circuit 23 The output is inverted to logic "H", while this transition goes through the delay circuit 24 to the exclusive OR circuit second input ^# 2.
Since it is not immediately transmitted to, the logical values of both inputs again differ from each other. Therefore, until the time τ set in the delay circuit 24 elapses, a pulse signal that rises to the logic “H” with the pulse width τ appears at the terminal T ₃ .

As is clear from the above, in the process of the winning device 1 converting from the first state to the second state, and also in the process of converting the second state to the first state, pulses having the same pulse width are equal. The signal is available at terminal T ₃ . Then, these signals can be used as a winning ball detection signal S _i that indicates that the winning device 1 has changed its state, that is, that there is a winning ball, and by extension, a specific value provided on the surface of the game board. It can also be used as a starting pulse or the like that triggers a variable winning device or a gaming device.

As described above, as the state conversion detection circuit 25, the configuration using the exclusive OR circuit 23 and the delay circuit 24 as in the illustrated embodiment is a very simple and reliable method, but of course,
The signal transition portion may be detected by using a differentiating circuit, a comparing circuit, or the like, as is normally done.

Further, as seen in the above embodiment, the winning device state detection signal S _s is first formed by the integrating circuit 18, and the winning device state detection signal S _s is processed to obtain the winning ball detection signal S _i.
Not only in the case where the magnetic sensitive switch 16 is turned on and off, a differential pulse is obtained in accordance with the turning on and off of the magnetic sensitive switch 16, which is used as a winning ball detection signal S _i , which is then processed, for example, With the aid of a T-type flip-flop circuit that inverts a logical value each time a differential pulse is generated,
It may be changed to obtain the winning device state detection signal S _s . However, in this case, it is generally necessary to perform the initial setting, as will be readily understood, so it is rather preferable to follow the steps of the above-described embodiment.

The above description of the embodiment is for the case where the magnetic sensitive switch 16 and the permanent magnet 17 are used as the switch mechanism.

However, in the present invention, not only the magnetic sensitive switch 16 and the permanent magnet 17 but also other switch mechanism can be used as the switch mechanism.

The embodiment shown in FIGS. 8 and 9 shows a case where the switch mechanism comprises a thick blocking portion 26 provided on the lower rear surface of the guide bottom plate 9 and an optical switch 27 provided on the wiring board 13. .

The optical switch 27 described above comprises a light-emitting element 28 and a light-receiving element 29 located on the left and right of the guide frame 7, which face each other.
Is in the first state, the guiding bottom plate 9 is horizontal, so the blocking portion 26
Is located above the optical switch 27, and the light of the light emitting element 28 irradiates the light receiving element 29 to turn off the optical switch 27. However, when the winning device 1 is converted to the second state, the guiding bottom plate 9 pivots upward, and the blocking section 26 blocks the light of the light emitting element 28, the light receiving element 29 is turned on.

Therefore, if the optical switch 27 described above is converted into the magnetic sensitive switch 16 in FIG.
The winning information of the hit ball entering the winning device 1 can be obtained from the same as the magnetic sensitive switch 16.

It should be noted that in FIGS. 8 and 9 described above, the reference numerals not described are the same as the same reference numerals in the above-described embodiment, and thus the description thereof will be omitted.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the above-described embodiments, and can be carried out in any manner unless the configuration described in the claims is changed. be able to.
