Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-and-ball game machine, and more particularly to a ball-and-ball game machine which suppresses the generation of static electricity during a game.

[0002]

2. Description of the Related Art In recent years, pachinko game machines are generally provided with various kinds of accessories in order to change the contents of the game and enhance the interest of the pachinko game.

A number of electronic circuits (for example, a role control circuit, a display control circuit, a game ball discharge control circuit, etc.) are incorporated in various controls including a role control. Microcomputers (hereinafter referred to simply as "microcomputers") have become complicated and have become complicated.

In a pachinko game machine, a game ball is made of iron (Fe) which is a conductor, and a plastic material or a celluloid material is often used in the moving path of the game ball, so that static electricity is easily generated. , It is easy to accumulate electric charge in the game ball.

In particular, since the game balls are circulated in the island facility from the bottom to the top and supplied to each game machine, for example, a game machine circulator in the island facility, a tank for the game balls, etc. In a place where a lot of game balls move and stop repeatedly, or in a place where the amount of movement of the game balls is large, such as a region that is released along the launch rail into the game region, static electricity is easily generated and the game balls move. Any location can be a source of static electricity.

Generally, an electronic circuit including the above microcomputer is very vulnerable to pulse-like noise (hereinafter, simply referred to as pulse-like noise) that becomes a high voltage in a short cycle, such as a discharge phenomenon due to static electricity, and is caused by static electricity. Due to the pulse noise, various failures such as circuit malfunction and operation stop occur.

Therefore, as a hardware countermeasure against such adverse effects of static electricity, for example, an integrating circuit is provided at the input part of each control circuit such as accessory control, display control, game ball discharge control and the like. By suppressing the effect from pulse noise due to the generation of static electricity, or by providing a conductor part in the tank and connecting the conductor part to the metal frame via a resistor, a game of contacting the conductor part The electric charge of the ball is released, the back mechanism arranged on the back of the game board is made of conductive resin, and the decorative member of the LCD is metal-plated and the metal-plated part is grounded via a resistor. Was there.

On the other hand, as a software measure, a reset interrupt is performed at predetermined time intervals by looping in the vicinity of a specific interrupt address where the microcomputer to be used is easy to jump to suppress runaway due to noise, or rises when counting pulses. Reads twice from the edge or falling edge for a predetermined time (the time corresponding to the system clock width) and compares the values of each read to cancel noise with a cycle shorter than the predetermined time, or RAM (Random RAM by writing a specific value in the specified area of the Access Memory) at the program end and checking the value in the specified area at the program top
I was checking to see if the data inside was corrupted.

[0009]

However, in a pachinko gaming machine in which such an electronic circuit is used, as described above, measures against the adverse effects of static electricity are taken from both the hardware and software sides. Although these measures are effective against relatively small-scale pulse noise, large-scale pulse noise is generated, such as discharge when the electric charge accumulated in the game ball is extremely large. In that case, there is a problem in that each electronic circuit is physically destroyed or its operation is stopped by applying a voltage exceeding the withstand voltage of the electronic circuit.

Specifically, for example, an LCD (Liquid Crystal Displa) used for the display portion of the center accessory.
y) and the cable for controlling the accessory control circuit are subject to pulsed noise, which disturbs the image to be displayed by the LCD, or, in the worst case, the driver IC (Integrated circuit) of the LCD or other Transistor,
Image display operation may be stopped due to physical destruction of LSI (Large Scale Integrated circuit),
The three-terminal regulator of the power supply unit locks to stop the 5V supply voltage supplied to each electronic circuit, or pulse noise is added to the accessory control circuit to cause the microcomputer in the accessory control circuit to perform software processing. There was a failure, such as a situation where it could not be recovered.

These obstacles are likely to occur in a portion vulnerable to pulse noise due to static electricity, and if countermeasures are taken for this weak portion, then another weak portion will be injured. However, the problem cannot be solved simply by taking measures against the pulse noise, and it is considered more effective to suppress the accumulation of electric charges in the game ball as much as possible due to the generation of static electricity that causes noise.

[Purpose] In view of the above problems, an object of the present invention is to suppress charge accumulation in a game ball during a game.

As shown in FIG. The discharge brush 8 is provided on the tip portion 6a, and the end portion 6b is formed by being rolled into a tubular shape.
Are supported by the mounting member 7.

FIG. 3 is an exploded perspective view of the return ball prevention device 5 as viewed from the back side.

As shown in FIG. 3, the mounting member 7 includes a lower frame 7
a and an upper frame 7b. The lower frame 7a and the upper frame 7b are respectively formed with groove portions 11 therein and through holes 12 respectively, and further, the lower frame 7a is engaged with the lower frame 7a. A stop projection 13 is provided.

FIG. 4 is a view showing a mounting state of the mounting member 7 on the game board 2.

Then, with the end portion 6b of the tongue piece 6 engaged with the groove portion 11 and the lower frame 7a and the upper frame 7b fitted together, as shown in FIG. By engaging with a locking hole 14 formed at the upper end position of the inner guide rail 3 of No. 3 and driving a nail 15 into the through hole 12,
The frames 7a and 7b are integrally fixed while supporting the tongue piece 6.

The discharge brush 8 is a ground brush for removing static electricity using a corona discharge type acrylonitrile-copper sulfide composite fiber. By being provided at the tip 6a of the tongue piece 6, the tip of the discharge brush 8 is The static electricity generated on the tongue 6 is discharged (neutralized) on the surface of the discharge brush 8 in a small scale without being brought into contact with the metallic portion, so that the static electricity is grounded. Incidentally, in this embodiment, the discharge brush 8
The distance d between the tip and the outer guardrail 4 is set to a value smaller than the radius of the game ball.

The protruding portion 9 is a vibration suppressing member formed of a rubber-based resin formed at the tip of the mounting member 7.
The vibration of the tongue piece 6 is quickly stopped by contacting the tongue piece 6 with a substantially central portion in a normal state.

Next, the operation (action) of this embodiment will be described.

First, a game ball launched from a game ball launching means (not shown) advances along the outer guide rail 4,
While pushing the tongue piece 6 open, the tongue piece 6 is launched into the game area in the game board 2.

Here, when the game ball is launched in a charged state, the tongue piece 6 is made of a conductive thin metal plate, so that the charge accumulated in the game ball at the time of contact with the tongue piece 6 is tongue. It moves to the piece 6 and is further grounded by a small-scale air discharge on the surface of the discharge brush 8 provided at the tip 6a of the tongue 6.

That is, since the electric charge accumulated in the game ball is neutralized when the game ball contacts the tongue piece 6, a large-scale discharge that causes pulse noise can be suppressed.

Incidentally, the tongue piece 6 is the groove portion 11 of the mounting member 7.
When the game ball is launched, the game ball is pushed and opened with the front wall portion of the groove portion 11 of the mounting member 7 as a fulcrum, and a smooth turning operation is obtained. As a result, the velocity decay in the launch of the game ball is suppressed.

Further, the game ball once entering the game area is prevented from returning to the guide rails 3, 4 side by the tongue piece 6 even if it tries to return to the guide rails 3, 4 side by the repulsive action of the nail or the like. Therefore, so-called ball returning is prevented.

Further, after the tongue piece 6 is pushed open when the game ball is launched, the tongue piece 6 is formed of an elastic member, so that the tongue piece 6 vibrates around the fulcrum described above, but the tongue piece 6 is in a normal state. Since the projection 9 hits the tongue piece 6 when returning to, the vibration of the tongue piece 6 is quickly stopped.

Therefore, in this embodiment, when the game ball is launched in the state where the charge is accumulated in the game ball due to the generation of static electricity, the charge accumulated in the game ball when the game ball contacts the tongue piece 6 is generated. The charge moved to the tongue 6 is further discharged by the discharge brush 8, and the charge accumulation on the game ball during the game is suppressed.

A preferred embodiment 2 of the present invention will be described below with reference to FIG.
This will be described with reference to FIG. In addition, in FIG. 5 and FIG.
The same parts as those in FIG. 1 are designated by the same reference numerals.

FIG. 5 is an enlarged front view showing the structure of the essential parts of the second embodiment.

In the first embodiment described above, the discharge brush 8 as the discharge member was provided at the tip 6a of the tongue piece 6, but
In this embodiment, the discharge brush 8 is provided at the tip 3a of the inner guide rail 3 and the tip of the discharge brush 8 is in contact with the tongue piece 6. In this contact state, the tongue piece 6 is always in contact even when the tongue piece 6 vibrates.

With the above structure, the game ball launched from the game ball launching means (not shown) advances along the outer guide rail 4 and pushes the tongue piece 6 open, as in the first embodiment. It is fired in the game area in the game board 2.

Here, when the game ball is launched in a charged state, the tongue piece 6 is made of a conductive thin metal plate, so that the charge accumulated in the game ball at the time of contact with the tongue piece 6 is the tongue. Move to piece 6. The tongue piece 6 is the inner guide rail 3
Since it comes into contact with the discharge brush 8 provided at the tip portion 3a of the battery, the electric charges moved to the tongue piece 6 are grounded by being discharged in the air on the surface of the discharge brush 8 in a small scale.

That is, since the electric charge accumulated in the game ball moves and is neutralized when the game ball contacts the tongue piece 6, as in the case of the above-mentioned first embodiment, it causes a large amount of pulse noise. Large-scale discharge can be suppressed.

Therefore, in this embodiment, when the game ball is launched in the state where the charge is accumulated in the game ball due to the generation of static electricity, the charge accumulated in the game ball when the game ball contacts the tongue piece 6 is generated. The electric charge that has moved to the tongue piece 6 is further discharged by the discharge brush 8 that is in contact with the tongue piece 6, and the charge accumulation on the game ball during the game is suppressed.

FIG. 6 is an enlarged front view showing the structure of the essential parts of the second embodiment which replaces FIG.

In this embodiment, as shown in FIG. 5, not only the discharge brush 8 is brought into contact with the tongue piece 6, but also the discharge brush 8 is extended to the inner area of the tongue piece 6 as shown in FIG. The discharged game ball is brought into direct contact with the discharge brush 8 to discharge, and in this case, when the game ball is launched in a state where electric charges are accumulated in the game ball due to generation of static electricity,
Since the electric charge accumulated in the game ball is discharged when the game ball directly contacts the discharge brush 8, the charge accumulation in the game ball during the game is suppressed.

A preferred third embodiment of the present invention will be described below with reference to FIG. In FIG. 7, the same parts as those in FIG. 1 are designated by the same reference numerals.

FIG. 7 is an enlarged front view showing the structure of the essential parts of the third embodiment.

In the second embodiment described above, the discharge brush 8 as the discharge member was provided at the tip portion 3a of the inner guide rail 3, but in this embodiment, the return ball prevention device 5 in the inner guide rail 3 is provided. The discharge brush 8 is provided at the position of the outer guide rail 4 corresponding to the provided position.
The tip of the tongue piece 6 is in contact with the surface of the tongue piece 6 on the game area side. It should be noted that this contact state is configured such that, even after the tongue piece 6 is separated from the discharge brush 8 by vibration, the tip end of the discharge brush 8 is crossed again and the tongue piece 6 comes into contact with the surface on the game area side.

With the above configuration, the game ball launched from the game ball launching means (not shown) advances along the outer guide rail 4 as in the first and second embodiments described above.
While pushing the tongue piece 6 open, the tongue piece 6 is launched into the game area in the game board 2.

Here, when the game ball is launched in a charged state, since the outer guide rail 4 is generally made of a conductive metal plate, the outer guide rail 4 accumulates in the game ball when it comes into contact with the outer guide rail 4. The generated charges are grounded by being discharged in the air on a small scale on the surface of the discharge brush 8. In this case, even if the outer guide rail 4 is not a conductor, the tongue piece 6 is made of a conductive thin metal plate, so that the charge accumulated in the game ball at the time of contact with the tongue piece 6 is transferred to the tongue piece 6. Since the tongue piece 6 moves and contacts the discharge brush 8 provided on the outer guide rail 4, the electric charge moved to the tongue piece 6 is grounded by a small-scale air discharge on the surface of the discharge brush 8.

That is, at least when the game ball comes into contact with the tongue piece 6, the charge accumulated in the game ball moves and is neutralized. Therefore, similar to the first and second embodiments, the pulse noise is generated. The large-scale discharge that causes

Therefore, in this embodiment, when the game ball is launched in the state where the charge is accumulated in the game ball due to the generation of static electricity, the charge accumulated in the game ball is passed through the outer guide rail 4 or the tongue piece 6. The discharge brush 8 discharges and suppresses charge accumulation in the game ball during the game.

As described above, in the present embodiment, like the area that is released along the launch rail into the game area,
In the place where the amount of movement of the game ball is large and static electricity is likely to be generated, the electric charge accumulated in the game ball is discharged in the air by the discharge brush 8, whereby the charge accumulation in the game ball during the game can be suppressed.

Although the invention made by the present inventor has been specifically described based on the preferred embodiments, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say.

For example, the bending angle θ at the substantially central portion of the tongue piece 6 in the above embodiment can take an arbitrary angle, and the tongue piece 6 in the return ball prevention device 5 can be barely set by increasing the angle θ. It is possible to slow down the firing speed of the game ball to the extent that it is pushed open to facilitate left-handing on the game board 2.

Regarding the shape of the tongue piece 6 in the above-described embodiment, instead of the shape shown in FIG. 3, for example, as shown in FIG. 8, a curved portion 6c is formed on the end portion 6b side of the tongue piece 6. As a result, the elasticity of the tongue piece 6 can be increased, and the shape may be changed according to the purpose.

Further, in the above embodiment, the protrusion 9 is made of rubber resin, but there is no restriction on the material of the protrusion 9, and the protrusion 9 may be integrally formed with the mounting member 7. .

In the above description, the invention mainly made by the inventor is applied to a pachinko game machine as a ball game machine, which is the field of application which is the background of the invention, but the invention is not limited thereto. Instead, it can be applied to, for example, a pin pole game machine or the like.
