DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine for playing a game using a chargeable game medium (for example, a pachinko ball), and more particularly, to a technique for removing static electricity charged on the game medium.

[0002]

2. Description of the Related Art For example, in a gaming machine such as a pachinko machine, a game medium is paid out from a storage section for storing a game medium to a tray via a game medium passage based on a game result of the player. . In such a gaming machine, when the game medium moves along the game medium path, static electricity is generated due to collision of the game medium with the wall surface or collision between the game media, and the game medium may be charged by the static electricity. there were. When the game medium is charged, this may cause a malfunction in the control circuit device that controls the entire game machine.
For this reason, techniques for removing electric charges charged on the game medium have been conventionally developed. In this conventional technique, a conductive material is disposed in a portion of a game medium passage that directly contacts a game medium, and charges charged in the game medium flow through the conductive material to remove static electricity charged in the game medium. It was like.

[0003]

However, in the above-described technology, when the amount of static electricity generated in the game medium increases and the amount of static electricity flowing from the game medium to the conductive material increases, the conductive material becomes electrically saturated. In some cases, it was not possible to remove static electricity from game media.

[0004] The present invention has been made in view of the above-described circumstances, and has as its object to provide a game system capable of removing static electricity charged on a game medium even when the amount of static electricity generated from the game medium increases. Offer machine.

[0005]

Means and Effects for Solving the Problems In order to solve the above-mentioned problems, a gaming machine according to claim 1 is a gaming machine for playing a game using a chargeable gaming medium, and stores a gaming medium. A medium storage unit, a tray for receiving game media to be paid out from the game medium storage unit, and a game medium passage communicating the game medium storage unit and the tray, wherein the game medium storage unit and / or the game A conductive member is provided on at least a part of a portion of the medium passage that directly contacts the game medium, and a predetermined position of the game medium storage portion and / or the game medium passage is higher than an electric resistance value of the conductive member. A current collecting member having a low electric resistance value is provided,
The current collecting member and the conductive member are electrically connected to a ground portion provided in the game machine. In the above-mentioned gaming machine, static electricity flowing from the game medium to the conductive member in the game medium storage section and / or the game medium passage flows to the ground section via the current collecting member. At this time, since the electric resistance of the current collecting member is lower than that of the conductive member, the static electricity flowing to the conductive member quickly flows to the current collecting member. Therefore, even if the static electricity generated from the game medium increases, the conductive member is less likely to be electrically saturated, and the static electricity can be removed from the game medium.

In the gaming machine according to the first aspect, the position where the conductive member and the current collecting member are provided is as follows:
It is preferable that the game medium passage is located near a portion where the game medium temporarily separates from the passage wall surface and comes into contact again (claim 2). According to such a configuration, the static electricity generated when the game medium separates from the passage wall surface and re-contacts (collides) is quickly flown to the ground portion via the conductive member and the current collecting member arranged in this portion. be able to.

In the gaming machine according to the first aspect, the position where the conductive member and the current collecting member are provided is as follows:
In the game medium passage, it is also preferable that the game media are located near a portion where the game media are discrete and re-contact with each other (claim 3). According to such a configuration, the game media are discrete
Static electricity generated at the time of re-contact can be quickly flowed to the ground via the conductive member and the current collecting member arranged in this portion.

Further, in the gaming machine according to the first aspect, the gaming medium storage section is configured to be supplied with a gaming medium from an external device separate from the gaming machine. It is preferable that the electric resistance value of the conductive member provided in the storage part is adjusted to be different from the electric resistance value of the conductive member provided in the game medium passage (claim 4). In such a configuration, the game medium stored in the game medium storage unit is charged with static electricity (so-called extrinsic static electricity) caused by an external device. Static electricity (so-called intrinsic static electricity) caused by the medium colliding with the passage or the like is charged. Therefore, since the energy levels of the static electricity that must be removed are different between the two, it is preferable to adjust the electric resistance values of the conductive members provided in both the game medium storage section and the game medium passage so as to be different. For example, when the energy level of the extrinsic static electricity increases, the amount of static electricity to be removed increases, so that the electric resistance value of the conductive member provided in the game medium storage unit is reduced to quickly remove the static electricity. Is preferred. Conversely, since intrinsic static electricity has a low energy level due to its cause, the electric resistance of the conductive member provided in the game medium passage may be increased.

By the way, the present inventor has conducted a number of experiments. As a result, the magnitude of spike noise (one of the causes of malfunction of the control circuit device) generated when removing static electricity from a charged game medium is as follows. It has been found that the electric resistance value of the conductive member that comes into contact with the game medium is significantly involved. That is, when the electric resistance value of the conductive member was variously changed (the peak value of the current flowing from the game medium to the conductive member was changed), it was confirmed that the noise observed in the control circuit device could be suppressed. Although the reason is not clear, if the electric resistance value of the conductive member in contact with the game medium is too small, a large current flows instantaneously, so that a large spike-like noise is generated, and the electric resistance value of the conductive member is appropriately adjusted. When the value is set, it is presumed that the peak of the current flowing from the game medium to the conductive member is suppressed, and the spike noise is also suppressed. A gaming machine according to the invention made on the basis of such knowledge is a gaming machine in which a game is played using a chargeable game medium, and a game medium storing unit for storing the game medium, and a game medium storing unit for storing the game medium. A receiving tray for receiving the game medium to be paid out from the unit, and a game medium passage communicating the game medium storing unit with the saucer, and directly contacting the game medium in the game medium storing unit and / or the game medium passage A conductive member is provided on at least a part of the portion, and the electric resistance value of the conductive member is adjusted such that the peak value of the current flowing from the charged game medium to the conductive member becomes a predetermined value. It is characterized by being. In the above-mentioned gaming machine, the electric resistance value of the conductive member provided in the game medium storage portion and / or the portion of the game medium passage that directly contacts the game medium is adjusted, so that the charged game medium is converted into the conductive member. The peak value of the current flowing through
As a result, it is possible to remove static electricity charged on the game medium while suppressing the magnitude of the generated spike noise. In addition, as the conductive member provided in the game medium storage section and / or the game medium passage, a member formed separately from the game medium storage section and the game medium passage may be provided. The storage section and / or the game medium passage itself may be directly formed of a conductive member.

You.

Here, in the ball game machine described in claim 5, it is preferable that the whole of the first ball passage and the second ball passage is formed of a conductive resin (claim 6). ). According to such a configuration, the contact time between the game ball and the conductive resin can be prolonged, so that even if the electric resistance value of the conductive resin is increased, static electricity can be sufficiently removed from the game ball. . Further, since the electric resistance value of the conductive resin can be increased, the peak value of the current flowing from the game ball to the conductive resin can be suppressed lower.

Further, in the ball game machine according to claim 5, the whole of the ball storage section, the payout device, the first ball passage, and the second ball passage are formed of conductive resin. In addition, it is preferable that a current collecting member having an electric resistance value lower than that of the conductive resin is provided in these predetermined portions, and the current collecting member is electrically connected to a ground portion provided in the gaming machine. According to such a configuration, the static electricity that has flowed through the conductive resin can efficiently flow to the ground via the current collecting member. At this time, it is preferable that the length and the electric resistance value of the first spherical passage and / or the second spherical passage are adjusted to predetermined values. By adjusting the length and the electric resistance value of the first ball passage and the second ball passage, the amount of static electricity that can be removed in these passages can be adjusted. That is, the longer the path length, the larger the amount of static electricity that can be removed, and the higher the electrical resistance value, the smaller the amount of static electricity that can be removed. Therefore, the passage length and the electric resistance may be adjusted according to the amount of static electricity to be removed in these passages (the amount of generated static electricity).

Further, in the ball-and-ball game machine according to claim 5, when the ball storage section is configured to be supplied with a game ball from an external device separate from the game machine, A current collecting member is provided in any one of the ball storage unit and the other payout device, the first ball passage, and the second ball passage, and a current collection member provided in the ball storage unit. It is preferable that the connection with the ground portion and the connection between the other current collecting member and the ground portion be electrically separated. In such a configuration, the game ball is charged with extrinsic static electricity in the ball storage portion, and the game ball is charged with intrinsic static electricity in other portions. Therefore, since the energy levels of the static electricity to be eliminated are different between the two, the connection between the current collecting member and the ground portion disposed on both of them is electrically separated so that the grounding portion is separated from the one current collecting member. Can be prevented from affecting the static elimination line that connects the other current collecting member to the ground. here,
"Electrically separate" means not only the case where the grounding part is completely separate, but also the case where a backflow prevention member (resistance, arrester, etc.) is provided between the grounding part and each current collecting member, and one of the current collecting members This also includes the case where the current flowing from the ground to the ground is prevented from flowing from the ground to the other current collecting member. In the ball game machine according to the fifth aspect, it is preferable that the current collecting member provided in the ball storage section is disposed on an inner wall of the ball storage section. This is because the extrinsic static electricity charged on the game ball in the ball storage section is preferably quickly removed because of its high energy level. However, when the conductivity of the ball storage unit is high (when the ball storage unit is made of metal) or the like, the current collecting member may be provided on the inner wall of the ball storage unit.

For example, a resistor, a diode, an arrester, or the like is used as the first and second 222s.

In the pachinko machine 1 configured as described above, the static electricity charged on the pachinko balls (game media) is removed as described below. That is, when the ground output terminal 204 of the power supply board 200 is grounded by the ground wire 203, the back set member 16
Of a pachinko ball flowing through a passage (a passage formed so as to surround the periphery of the control box device 6) such as a ball guiding gutter 71, an upper discharge gutter 72, a ball discharge device 73, a lower discharge gutter 74, and a ball discharge gutter 76. Static electricity (intrinsic static electricity) generated by friction or the like and charged on the pachinko balls flows from the pachinko balls to the back set member 16 formed of a conductive resin. The static electricity flowing to the back set member 16 is directly transmitted from the back set member 16.
Alternatively, the current collecting members 71a, 7 provided on the back set member 16
3a, 74a, 76a, 76b and conductive lines 71b, 73
It flows to the mounting screw 126 via b, 74b, 76c, and flows from the mounting screw 126 to the first ground input terminal 215 via the connection line 231. Then, the static electricity flowing to the first ground input terminal 215 flows to the ground circuit 210 via the backflow prevention element 220, and flows to the ground line 203 via the ground output terminal 204. Here, the ball guiding gutter 71, the upper discharge gutter 72, the ball discharge device 73, the lower discharge gutter 74, and the ball discharge gutter 76 are adjusted so that the electric resistance value becomes a predetermined value. The peak value of the current flowing through these members can be kept low. In addition, current collecting members 71b to 76c are provided at predetermined positions of these members (near a wall surface where the pachinko ball collides: a portion where static electricity is likely to be generated) to facilitate removing static electricity from these wall surfaces.
For these reasons, it is possible to prevent spike noise from being generated due to static electricity charged in the pachinko ball and the back set member 16, thereby preventing malfunctions of electronic components such as the control box device 6 and the like. it can.

The static electricity generated in the firing handle device 20 (static electricity flowing from the player: a kind of so-called extrinsic static electricity) is supplied to the electric connection means 240, the second ground input terminal 216, the backflow prevention element 221, and the ground. Circuit 210 and the ground wire 20 via the ground output terminal 204.

For this reason, the static electricity (extrinsic static electricity) generated in the firing handle device 20 and the ball tank 70 is quickly removed by a different path from the above-described intrinsic static electricity, and the generation of noise is prevented. Further, since these noise elimination paths are electrically separated from the intrinsic noise elimination paths, they do not affect each other (the current flowing to the ground circuit 210 does not flow backward).

On the other hand, the earth circuit 210 of the power supply board 200

Through the conductive connection member 160. Thereafter, the static electricity passes through the hinge plate 102 and the fixing pin 104 of the base frame hinge mechanism 100 and the hinge plate 1 of the front frame hinge mechanism 140.
It flows to the reinforcing member 31 a of the front frame 30 through the 43, the hinge shaft 142, and the bearing cylinder 141. The static electricity flowing from the pachinko ball to the ball tank 70 is also directly transferred to the back set member 16.
From the above, it flows to the hinge mechanism 120 for back setting, and similarly flows to the reinforcing member 31a of the front frame 30. Here, the reinforcing member 31a is made of a conductive metal plate such as an iron plate, and has a large surface area over substantially the entire area of the front frame 30. For this reason,
The static electricity flowing to the reinforcing member 31a is satisfactorily discharged on the large surface area of the reinforcing member 31a. In this way, the static electricity charged on the back-set member 16 can be discharged by the reinforcing member 31a. Therefore, even when the ground output terminal 204 of the power supply board 200 is not grounded by the ground wire 203, the pachinko ball can be easily removed. Static electricity can be removed. Also at this time, since the electric resistance value is adjusted so that the peak value of the current flowing from the pachinko ball to the back setting member 16 is suppressed low, generation of large spike noise is prevented.

For this reason, the static electricity flowing to the back setting member 16 can be quickly removed, and the malfunction of the electronic components and the like such as the control box device 6 can be more reliably prevented.

The ground circuit 210 is connected to the power supply board 200.
When the ground is connected to the substrate ground via the backflow prevention element 212, a part of the static electricity flowing to the back-set member 16 is transferred to the back-set hinge mechanism 120 and the connection line 2.
31, first ground input terminal 215, backflow prevention element 22
