Description

[Detailed description of the invention] The present invention relates to a ball hitting device for a pachinko game machine.

Conventionally, pachinko gaming machines equipped with so-called electric ball striking devices have been known, and in these types of pachinko gaming machines, a driving power source such as a motor or rotary solenoid fixed to a predetermined location on the base frame is protruded from the front of the gaming machine. It is actuated by a microswitch or the like that is opened and closed by the rotation of the ball-striking operation section, and the elastic force of the ball-striking pestle is adjusted in accordance with the amount of rotation of the operation section.

Therefore, in this type of ball-hitting device, if the rotation angle of the ball-striking operation part is fixed with a coin or a matchstick, the pachinko machine will automatically perform the ball-striking operation even if the f&m player leaves the pachinko machine. , there was a risk that players would be induced to play illegally.

In order to prevent such illegal games, in recent years some pachinko game machines have been installed that are equipped with a touch sensor that detects a floating human body, and that uses the detection output to operate a ball hitting device.

FIG. 1 is a circuit diagram of a conventional titanium sensor of this type, in which reference numeral 101 indicates an oscillator constituted by a C-MOS gate;
102 is a flip-flop constituted by a NOR gate; 103 is a transistor for binary switching; 104 is a relay circuit that operates in response to on/off of the transistor 103; and 05 controls the operating range of the L transistor 103. In the voltage holding circuit, 106a is a resistor, 106b is a capacitor, and 107 is an electrode plate for detecting the stray capacitance of the human body.

To explain its operation, the oscillator 101 generates pulses at a period determined by its time constant from the time the power is turned on, and the pulses are simultaneously applied to the seso I/input S and the reset input R of the flip-flop 102. In this flip-flop 102, when the node input S and the reset input R compete at the same time, the reset input R takes priority, so in this state, the Q output of the flip-flop 102 is always at the L level, and the voltage holding circuit is Capacitor 105 is not charged. Therefore, transistor 103 is cut off and relay circuit 104 is also broken.

On the other hand, the electrode plate 107 is placed in a place that the player always touches during the game. Therefore, when the game starts, the resistance 106a and the capacitor 106
Since b constitutes the delay circuit 106, the pulse applied to the set force S of the flip-flop 102 is delayed by a time determined by its time constant. Therefore, the flip-flop 102 repeats cent reset, and a pulse-like signal is derived from its Q output.

On the other hand, since the time constant of the voltage holding circuit 105 is set longer than the oscillation period of the flip-flop 102 performed as described above, the capacitor of the voltage holding circuit 105 is charged by the pulse output from the flip-flop 102. Then, when a certain number of pulses are applied, the transistor 103 turns on, the relay circuit 104 is metered, and the pachinko game machine starts a ball hitting operation.

Then, when the player releases his hand from the electrode plate 107,
Since the capacitor of the voltage holding circuit 105 is discharged and the transistor 103 is cut off, the pachinko game machine ends the ball hitting operation.

In such a ball hitting device, even if the ball hitting operation section is fixed at a predetermined rotation angle, the resistor 106a and capacitor 106
Since the ball-hitting operation cannot be performed unless the resistor 106a and the capacitor 106b operate as a delay circuit, the above-mentioned illegal games can be prevented to a certain extent.
In order for the electrode plate 10 to operate as a delay circuit, the electrode plate 10 is not necessarily required.
It is not necessary for the player to touch the terminal 7; for example, if the electrode plate 107 is grounded with a piece of wire or silver paper from a cigarette, the resistor 106a can be grounded.
Since the capacitor 106b and the capacitor 106b operate as a delay circuit, fraudulent gaming cannot be completely prevented.

The present invention was made in view of the current situation, and
It is an object of the present invention to provide a ball hitting device for a pachinko game machine that can more effectively prevent the above-mentioned fraudulent acts.

To summarize, the ball hitting device for a pachinko game machine of the present invention is a pachinko game machine equipped with a so-called electric ball hitting device, in which at least one pair of electrode plates is disposed at a part of the ball hitting operation part that the human body comes into contact with, and the electrode plate By causing the oscillator to oscillate due to the capacitance generated between the electrode plates when the player touches the ball, and by operating the ball hitting motor when the oscillator oscillates, it is possible for the player to touch the ball hitting operation section. When the ball is not in position, the ball cannot be hit.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a mechanical diagram of the ball hitting device.

First, ■ indicates a base frame of a pachinko game machine, and a support frame 3 is fixed to a substrate 2 fixed to a base frame 1.

A ball hitting rod 4 is rotatably supported on this support frame 3, and a ball hitting portion 5 at the tip of the ball hitting rod 4 faces a ball hitting position 7 on a guide rail 6. Further, a board 9 on which the motor 8 is mounted is fixed to the support frame 3, and the cam tip of the trilobal cam 11 connected to the rotating shaft 10 of the motor 8 is rotated to the tip of the roller stay 13 fixed to the ball hitting rod 4. It faces the side of the movably supported roller 12.

Furthermore, a handle 14 and an operating lever 15 are provided on the surface of the base frame 1.
is provided, and the rotation shaft 16 of this operating lever 15 is connected to the base frame 1.
It penetrates through and protrudes to the back side of the base frame 1. This rotation axis 1
A take-up pulley 17 is provided at the tip of the wire 6, and the other end of the wire 1B wound around the take-up pulley 17 is fixed to one end of the traction force adjustment plate 21 via pulleys 19 and 20.

This traction force adjusting plate 21 is provided with a plurality of holes LJ, one end of the traction spring 22 is locked in one of the holes corresponding to the desired traction force, and the other end of the traction spring 22 is connected to the batting rod 4.
is locked.

Further, a pin 23 fixed to the take-up pulley 17 faces a contact 25 of a microswitch 24.

Therefore, when the player rotates the operating lever 15 by an appropriate angle in the direction of the arrow a, the bottle 23 moves to the contact point 2 of the microswitch 24.
5 and the motor 8 starts operating. This motor 8
In connection with the operation, the trilobal cam 11 rotates in the direction of the arrow, the cam tip of the trilobal cam 11 presses against the side surface of the roller 12, and the ball striking rod 4 resists the tensile force of the traction spring 22. It rotates in the direction of arrow C. As the motor 8 continues to rotate,
The engagement between the trilobal cam 11 and the roller 12 is released, and the ball hitting rod 4
is rotated back by the tensile force of the traction spring 22, and the batting rod 4
The ball hitting part 5 at the tip of the ball hits the pachinko ball at the ball hitting position 7.

Furthermore, the ball-striking device of this embodiment is characterized in that a pair of electrode plates are disposed at the part of the ball-striking operation section that comes into contact with the human body, and when a player touches the pair of electrode plates, the electrode plate An oscillator is caused to oscillate by the capacitance generated between the two, and when the oscillation of the oscillator is detected, a driving power source such as the motor 8 is operated.

The pair of electrode plates may be placed anywhere as long as the player touches them during the game, but in this embodiment, as shown in FIG. The plates 31 and 32 are arranged so that capacitance is generated between the electrode plates 31 and 32 only when a player is actually playing a game.

Note that the leads 33 of the electrode plates 31 and 32 pass through the rotation shaft I6 and are transmitted to a control circuit to be described later.

FIG. 4 is a circuit diagram showing one embodiment of this control circuit,
Regarding the elements explained in Figs. 2 and 3,
The same reference numerals as in the figure and FIG. 3 are given.

First, reference numerals 8 and 25 in the figure indicate the contacts 25 of the motor 8 and the microswitch 24 shown in FIG. performs a ball-striking motion. In this embodiment, the operation of the relay circuit 40 is controlled by the conduction of the i-transistor TR which is grounded to the emitter.

That is, in this embodiment, the transistor TR is connected in series between the excitation coil 42 of the relay circuit 40 and the power source and the ground, and when the transistor TR is turned on, the relay contact 41 is made, and the transistor TR is turned off. When this occurs, the relay contact 41 is configured to break.

Further, in the figure, 50 is a voltage holding circuit for controlling on/off of the above-mentioned transistor TR, and the voltage holding circuit 5
A base current is supplied from 0 to the transistor TR.

The above configuration is well known in the past, but the present invention is characterized in that the voltage holding circuit 50 is charged by pulses generated by the oscillator 60, and the player touches the electrode plates 31 and 32 with tentacles. The oscillator 60 is designed to perform oscillation operation only when the oscillator is in use.

That is, the oscillator 60 is a pulse oscillator whose output logic is sequentially inverted by repeatedly charging and discharging the capacitor C. To describe the specific operation, when the output of the inverter IOI becomes logic 1, the capacitor C is not charged. Once started, a charging current flows through the resistor Rot. Therefore, a voltage is generated across the resistor Rot, and the level at point A is logic 1.
become. Accordingly, inverter ■・. The second input point is also resistor R.
[,2 pulls it up to logic 1, the level at point B becomes logic O, and the circuit becomes stable.

Thereafter, as the charging of the capacitor C progresses, the charging current flowing through the resistor ROI decreases, so that the level at point A gradually decreases and eventually falls below the threshold level. Then, the level at the input point of inverter 102 becomes logic O, the level at the output point of inverter Iθ2 becomes logic 1, and the level at the output point of inverter rot becomes logic 0.

Therefore, capacitor C is charged in the opposite direction and resistor Rot
A voltage in the opposite direction is generated across the terminal, and the level at point A is logic O.
become. Therefore, the inverter ■. If the level at the input point of inverter ro2 becomes logic 0, the level at the output point of inverter ro2 becomes logic 1, and the circuit becomes stable.

Then, as capacitor C is charged, resistor RO
Since the charging current flowing through I decreases and the voltage developed across the resistor Rot decreases, the level at the output point of the inverter ro2 becomes logic O. Thereafter, the above operation is repeated while charging and discharging the capacitor C in the same manner, so that a periodic pulse waveform is output from the inverter Cot.

By the way, the oscillator with this ridge structure is usually a C-MOS gamer.
- and is composed of an external capacitor and resistor,
In this embodiment, when a player touches the electrode plates 31 and 32 provided on the outer periphery of the ball-striking operation part, this electrode plate 3
The capacitance generated equivalently by the human body interposed between 1 and 32 is the capacitance component of the capacitor constituting the oscillator 60.

Therefore, according to this embodiment, the oscillator 60 performs the oscillation operation only when a capacitance component is generated between the electrode plates 31 and 32 when the player touches the electrode plates 31 and 32, so that the player can actually When the game is not being played, the pachinko game machine does not perform ball hitting operations.

Next, - the operation of the above embodiment will be explained.

First, when the power in the store is turned on, the control system shown in FIG. 4 becomes ready for operation.

When the player rotates the operating lever 15 to start playing in this state, the pin 23 is connected to the contact point 25 of the micro switch 24.
Close.

In addition, since the electrode plates 31 and 32 are provided on the outer periphery of the operating lever 15, when a player puts his/her hand on the ball-striking operation part, the electrode plates 31 and 32 are always touched by the player's tentacles.
A capacitance component C is equivalently generated in between, and the oscillator 60 starts oscillating. The pulse generated by the oscillator 60 is applied to the voltage holding circuit 50 via the diode D, and charging of the capacitor 51 is started.

1. Therefore, if the time constant is determined so that the discharging current of the capacitor 51 becomes smaller than the charging current of the capacitor 51, the level of the capacitor 51 will gradually become 1. -The base current begins to flow through the transistor TR, and the transistor TR turns on.

Therefore, the coil 42 of the relay circuit 40 is energized, the relay contact 41 is closed, and the motor 8 is supplied with driving current from the power source 70.

As a result, the motor 8 starts rotating, and the rotation shaft 1 of the motor 8
The trilobal cam 11 connected to the cam 1 also rotates in the direction indicated by the arrow.

Thereafter, as explained with reference to FIG. 2, the batting rod 4 hits the pachinko ball at the batting position 7.

Now, suppose that in this state, the player fixes the rotation angle of the operating lever 15 using a matchstick or the like for the purpose of cheating.

When the rotation angle of the control lever 5 is fixed, the contact 25 remains on, but the electrode plates 31 and 32 are cut off from contact with the human body, so the capacitance component between the electrode plates 31 and 2 and 32 is C disappears and oscillator 60 stops oscillating.

On the other hand, the charge accumulated in the capacitor 51 is discharged via the transistor TR, and when the pulse is no longer applied from the oscillator 60, the level of the capacitor 51 decreases. When the level of the capacitor 51 drops below a predetermined level, no base current flows through the transistor TR, and the transistor TR is turned off.

Therefore, the relay contact 41 is also broken and the drive current of the motor 8 is also cut off, making it impossible to continue the game.

As explained above, according to the present invention, even if the player fixes the rotation angle of the operating lever 15 for the purpose of cheating,
Since the pachinko game is immediately stopped, it is possible to effectively prevent fraudulent actions such as automatically hitting a ball even when no player is present.

However, in the case of the present invention, unless a human body is present between the electrode plates 31 and 32, no capacitance is generated between the electrode plates 31 and 32, so even if the electrode plates 31 and 32 are grounded, it is completely meaningless. - The above-mentioned fraudulent acts can be more effectively prevented.

In addition, in the description -1-, an example was shown in which the electrode plates 31 and 32 were arranged around the outer periphery of the operating lever 15, but the electrode plates 3I and 32
may be placed at any location as long as it is a location that players are sure to touch.

In addition, in Section 2, an example was shown using an oscillator composed of C-MOS gates, which performs oscillation operation.
It goes without saying that an oscillator of any configuration may be used as long as the presence of a capacitive component is essential.

Furthermore, although the example in which the signal obtained from the detection system is transmitted to the motor drive system using a relay circuit is shown in the section "-," various other means such as a photocoupler may be used as this transmission means.

Furthermore, although an example in which an AC motor is used as the driving power source is shown above, the present invention may be applied to other driving power sources as long as the driving power source uses electric power, such as a DC motor or a rotary solenoid. I can do it.
