DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine, and more particularly to a game machine in which noise due to static electricity charged on the surface of a game ball or a tank rail is reliably absorbed by a noise absorbing circuit, and noise countermeasures are strengthened. .

[0002]

2. Description of the Related Art Conventionally, in a ball-and-ball game machine such as a pachinko machine, a back mechanism plate is detachably mounted on the back side of a front frame.
A ball tank and a tank rail extending therefrom are provided above the back mechanism plate, and game balls conveyed from game ball conveyance paths provided for each island structure of the pachinko hall are supplied to the ball tank. . A payout device for paying out game balls is provided on a side portion of the back mechanism plate, and a payout ball guiding passage connected to the payout device is provided below the back mechanism plate.
Therefore, when the game ball wins the winning means, the payout device is driven, a predetermined number of game balls are paid out as a prize ball,
These paid out game balls are paid out to the upper plate from the upper plate outlet through the payout ball guiding passage.

[0003] In addition, out balls and winning balls used for ball games are collected at the hole side through a game ball collection path, polished by a polishing device, and then returned to a ball tank via a game ball conveyance path. It is being supplied. By the way, since the paths such as the game ball transport path, the ball tank, the tank rail and the payout ball guide path are made of a synthetic resin insulator, static electricity generated when the game balls are polished by the polishing device is charged to the game balls. In the middle of a game ball being conveyed along the game ball conveyance path on the hole side, static electricity is generated when the game ball makes frictional contact with or collides with the path or the game ball, and the game ball is charged (so-called contact charging). May be.

Further, the conveyed game balls are supplied to the ball tank by dropping, and when the ball is supplied from the ball tank to the next tank rail by dropping, the game ball is supplied to the ball tank, the tank rail or the like. Static electricity is also generated when frictionally contacting or colliding with a game ball, and the static electricity is likely to be charged to the game ball. This means that some of the static electricity generated in the game ball is transferred to the insulator passage when the game ball is made of metal, but moves along the passage of the insulator made of synthetic resin while colliding with the passage or the game ball. Although the static electricity is also charged in the path of the insulator, the game ball moving on the tank rail from the ball tank tends to be charged with the static electricity.

When these electrostatically charged game balls move in sequence from the ball tank to the tank rail or the dispensing device, the game balls themselves act as antennas to discharge static electricity in the air or generate a magnetic field. The noise due to these electrostatic discharges and electrostatic inductions occurs, adversely affects the control signals of various control units that control game control, etc., and these control units may stop operating or malfunction. is there. Therefore, conventionally, a metal plate is provided in a part of a game ball dispensing passage in which a game ball such as a ball tank or a tank rail collides during movement and static electricity is easily generated, and the inner frame is rotatably mounted on the outer frame. The connected hinge metal and the metal plate are connected by a ground line so that static electricity charged on the game ball is grounded to the hinge metal.

[0006]

As described above, a metal plate is provided in a part of a passage where a game ball easily contacts while moving along a game ball payout passage, and static electricity charged on the game ball is discharged from the metal plate or the metal plate. Although it is designed to escape by grounding to the hinge fitting of the inner frame via the ground wire, the hinge fitting is small and not a full-fledged ground plate, so that at present the sufficient grounding effect is not obtained. is there. Therefore, noise caused by electrostatic discharge or electrostatic induction from a moving game ball has a bad influence on various control boards or the like that control game control, which causes a problem of hindering game control. I have.

[0007] Further, noise due to static electricity charged in a passage such as a ball tank or a tank rail, which is an insulator, adversely affects game control. The purpose of the present invention is
To effectively absorb noise due to static electricity charged on the surface of the tank rail and game balls moving on the tank rail so that noise countermeasures can be strengthened, and to various control boards that control game control. To prevent adverse effects due to noise.

By the way, since these ball tanks and tank rails are insulating paths such as synthetic resin, when game balls supplied from the outside are supplied to the tank rails through the ball tank,
When a game ball collides with a tank rail or a game ball, static electricity is generated, and the static electricity may be charged on the surface of the game ball or the tank rail.

However, the game ball directly contacts the conductive member provided on the tank rail, or indirectly contacts through the game ball. As a result, the static electricity charged on the surface of the game ball and the tank rail is positively removed by the conductive member, guided to the noise absorbing circuit via the ground line, etc., and the noise absorbing circuit reliably absorbs the noise due to the static electricity. Therefore, noise countermeasures can be strengthened.

When the conductive member is provided on the tank rail so as to be able to contact the game ball (claim 2), the game ball supplied from the ball tank and moving on the tank rail is provided. The contact with the conductive member can be ensured, and the static electricity charged on the game ball can be effectively and reliably removed.

In the case where the conductive member is provided at the bottom of the tank rail (claim 3), the game is performed by moving the tank rail from the ball tank to the conductive member provided on the tank rail. Because each of the spheres comes in direct contact,
Even when static electricity is charged on the tank rail or the game ball moving on the tank rail, the static electricity charged on the bottom of the game ball and the tank rail can be effectively and reliably removed when the game ball is moved.

In the case where the conductive member is provided on a partition wall between a plurality of rail portions formed on the tank rail (claim 4), the conductive member provided on the partition wall may be provided on the partition wall. Since each of the game balls supplied from the ball tank and moving on the tank rail comes into direct contact with each other, the same operation as in claim 3 is effected.

In the case where the conductive member is provided on a rocking plate for detecting a broken ball pivotally supported on a tank rail (claim 5), the conductive member provided on the rocking plate may be provided. Since most of the game balls supplied from the ball tank by dropping from the ball tank come into direct contact with the members, even if the swing plate and the game balls supplied from the ball tank are charged with static electricity, these game balls and rocking Static electricity charged on the plate can be effectively and reliably removed.

In the case where the noise absorbing circuit has a surge absorbing element for absorbing a surge component up to a predetermined voltage and a varistor for absorbing noise that cannot be absorbed by the surge absorbing element (claim 6), The surge component of the noise generated up to a predetermined voltage is absorbed by the surge absorbing element, and thereafter, weak noise that cannot be absorbed by the surge absorbing element is absorbed by the varistor. For example, even for a large noise having a surge voltage of 200 V or more, the surge component up to about 200 V is absorbed by the surge absorbing element, and the remaining weak noise can be reliably absorbed by the varistor.

When the noise absorbing circuit is provided on a power supply board (claim 7), the plurality of control boards for game control are guided to the power supply board without affecting the noise by static electricity. This power supply board can absorb noise.

The ball-out state can be detected by turning on the ball-out detection switch 78. However, due to the weight of the plurality of game balls 75 supplied from the ball tank 33, the swinging plate 76 is always switched to the substantially horizontal ball supply state, and the ball out detection switch 78 is not operated. .

As shown in FIGS. 7 and 8, on the upper surface of the rail main body bottom portion 34a except for the two rail grooves 34e, the static electricity charged on the surface of the game ball 75 or the tank rail 34 is attached to the game ball 75. Strip-shaped conductive member 79 made of metal such as a thin copper plate for positively removing by contact with
Are affixed to each of the four locations. Game balls 75 supplied to the ball tank 33 from an external game ball transport path (not shown)
Is supplied onto the swing plate 76 from a discharge port (not shown) formed at the right end of the ball tank 33 by dropping. Then, the supplied game ball 75 moves through the two passages partitioned by the partition wall 76a, then moves to the downstream end along the two rail portions 34f of the tank rail 34, and then sends the two balls to the payout device 35. Supplied in state.

Each of the strip-shaped conductive members 79 provided at these four locations is connected to one end of a ground line 92.
The other end of the ground line 92 is connected to a power supply board 45 described later.
Is connected to a noise absorption circuit 87 provided in the first embodiment. next,
The above-described power supply board 45 will be described with reference to FIG. AC24 supplied from outside via connector 80
V input lines 81a and 81b include a 24V generation circuit 82 for generating 24V DC, a 5V generation circuit 83 for generating 5V DC, and a 12V generation circuit 8 for generating 12V DC.

The noise absorbing circuit 87 is connected to the input lines 81a and 81b at the preceding stage of the 24V generating circuit 82. The noise absorbing circuit 87 will be described. A surge absorbing element 88 and a varistor 89 are connected in series and connected to an input line 81a.
The surge absorbing element 88 and the varistor 90 are connected in series and connected to the input line 81b.

The other end of the ground line 92 is connected to the surge absorbing element 88 via a connector 91. The surge absorbing element 88 is separated from the surge absorbing element 88 by a small gap.
A pair of electrodes are provided to face each other, and a predetermined voltage (for example, 200
This element immediately absorbs surge components up to V) (voltages and currents such as noise whose magnitude changes rapidly). Noise that cannot be absorbed by the surge absorbing element 88 is dulled by the varistors 89 and 90 so as to be surely absorbed. Next, the game ball 7 supplied from the ball tank 33
The operation when the static electricity charged on the surface of the fuel cell 5 and the tank rail 34 is removed by the conductive member 79 and absorbed by the noise absorbing circuit 87 will be described.

The game balls 75 polished by the hole-side polishing device (not shown) are supplied to a ball tank 33 via a game ball transfer path (not shown), which is an insulator, and are temporarily stored therein. Since the game balls 75 are supplied to the tank rail 34, the plurality of game balls 75 supplied to the tank rail 34 may include static electricity generated when being polished by the polishing device, or may be in the middle of being conveyed on the game ball conveyance path, or may be a ball tank. When the game ball 75 is supplied by dropping to the tank rail 33 or the tank rail 34, static electricity is generated when the game ball 75 frictionally contacts or collides with the ball tank 33, the tank rail 34 or the game ball 75, and the generated static electricity is played. It is highly possible that the sphere 75 is charged (so-called contact charging).

In this case, although the game ball 75 is made of metal, it is generated by static electricity generated when the ball 75 collides with the ball tank 3, the tank rail 34, or the game ball 75, which is an insulator made of synthetic resin, and moves while being in frictional contact. Is transferred to the tank rail 34, and the surface of the tank rail 34 is also charged with static electricity. However, the static electricity may be mainly charged on the game ball 75, and the game ball 75 is charged in this charged state. To move to the downstream end along the two rail portions 34f of the tank rail 34, respectively.

By the way, as described above, the static electricity is generated in the game ball 75.
Even when the surface of the tank rail 34 is charged, when the game ball 75 moves along the two rails 34f, the plurality of game balls 75 swing freely to the lower side of the ball tank 33. Each of the game balls 75 comes into direct contact with the conductive member 79 because they are aligned in a single layer by the pivoted ball breaking members 32. As a result, the static electricity charged on the game ball 75 and the static electricity charged on the surface of the tank rail 34 are positively removed by the conductive member 79, and are reliably supplied to the noise absorbing circuit 87 via the ground line 92.

In the noise absorbing circuit 87, noise caused by static electricity removed by the conductive member 79 is, for example, as shown in FIG.
As shown in (a), even when a high surge voltage is present (refer to the input-side noise waveform), as shown in the output-side noise waveform of FIG. 10B, for example, a surge component up to 200 V is immediately absorbed. ing. Thereafter, the weak noise that cannot be absorbed by the surge absorbing element 88 is removed by the varistors 89 and 9.
