Abstract

PROBLEM TO BE SOLVED: To prevent the generation of noise by effectively discharging electric charges even when a game medium passing through a route inside a game machine is electrified without complicating the assembly process of the game machine. SOLUTION: A storage container 38 is formed of an ABS resin containing 8 wt.% carbon and the storage container 38 is connected to the metal fitting 209 of a mechanism plate by wiring 211. Thus, the potential of the storage container 38 is the same as the potential of the metal fitting 209 of the mechanism plate. Also, the base body of the mechanism plate and the passage of game balls are formed of synthetic resin containing stainless steel fibers and the base body is in contact with the metal fitting 209. The metal fitting 209 is grounded through a payout control board 37 and a card unit 50. Thus, the potential of the storage container 38 and the base body, or the like, is a ground level. Also, since it is not required to use a metallic ground plate, or the like, as an antistatic member, the assembly process of the game machine is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine in which a game is played in response to a player's operation, and more particularly to a game machine configured to pay out a game medium in accordance with the game.

[0002]

2. Description of the Related Art As a gaming machine, a game ball is fired into a game area by a launching device, and when a game ball wins in a winning area such as a winning opening provided in the game area, a predetermined number of game balls serve as prize balls. There are gaming machines paid out to players. Since the gaming machine pays out prize balls in accordance with a prize, it is necessary to provide at least a payout mechanism capable of paying out prize balls.

[0003] A player borrows a game ball and plays a game using the borrowed game ball and the game ball paid out according to a winning. At that time, a lending request for a game ball from a player is once received by a lending request processing device such as a card unit, and the lending control means of the gaming machine receives a lending request from the player by communicating with the lending request processing device. Then, the lending management means controls the payout mechanism to lend the game balls. Alternatively, by inserting coins into a ball rental machine that pays out game balls according to coin insertion,
Some gaming machines assume that a player borrows a game ball from a ball rental machine.

In general, the supply of gaming balls to the payout mechanism of each gaming machine in a game store is performed collectively from a supply mechanism provided on a game machine installation island in the game store. That is, game balls are supplied from outside the gaming machine. Gaming balls supplied from outside the gaming machine need to be guided to the payout mechanism provided inside the gaming machine,
Game balls supplied from the outside are stored in a storage tank installed at an upper portion of the gaming machine, and the structure is often configured to flow down from the storage tank to a payout mechanism. Further, a structure is often adopted in which game balls paid out from the payout mechanism flow down from the payout mechanism to a dish storage section provided on the front face of the gaming machine. Due to the demand for cost reduction and weight reduction of the gaming machine, the downflow path of the game ball is realized by a synthetic resin flow path.

[0005] Then, there is a possibility that the game balls are charged due to friction or the like between the game balls and the downflow path, and a discharge phenomenon occurs between the game balls. Then, due to the discharge, noise may be put on various electric components provided in the gaming machine and signal lines and power supply lines of the board. As a result, noise may cause a malfunction or a signal error.

[0006]

SUMMARY OF THE INVENTION In order to prevent charging of game balls in a supply path, a conductor plate made of metal or the like is installed in a ball passage portion of a mechanism plate provided with a downflow path for game balls. The structure which grounds (grounds) a board was adopted. However, when a conductive plate such as a metal plate is provided, there are problems that the weight of the mechanism plate increases and the assembling process of the gaming machine becomes complicated. Further, when the game ball comes into contact with a grounded metal or other conductive plate, there is also a possibility that electric charges are rapidly moved between the game ball and the conductive plate and noise is generated. In addition, in a portion of the gaming machine where the game ball passes, a charge transfer effect (discharge effect) from the game ball is provided in a portion where the game ball having a particularly large amount of charge passes, such as a storage tank to which the game ball is supplied from the outside. Although a synthetic resin member containing carbon may be used for emphasis, it is difficult to sufficiently exert an antistatic effect of a game ball when only a synthetic resin member containing carbon is used.

In view of the above, the present invention provides a game machine having a game medium payout mechanism, which does not complicate the assembling process of the game machine, and reduces the effect of the charge even if the game medium passing through the path in the game machine is charged. It is an object of the present invention to provide a structure capable of preventing the occurrence of noise by emitting the noise.

As shown in FIG. 1, on the lower surface of the glass door frame 2, there is a hit ball supply tray (reservoir) 3. Below the hitting ball supply tray 3, a surplus ball receiving tray 4 for storing game balls overflowing from the hitting ball supply tray 3 and a hitting operation handle (operation knob) 5 for firing a hitting ball are provided. Behind the glass door frame 2,
The game board 6 is detachably attached. The game board 6 is a structure that includes a plate-like body constituting the board and various components attached to the plate-like body. A game area 7 is formed on the front of the game board 6.

In the vicinity of the center of the game area 7, a variable display section (special symbol display device) 9 for variably displaying a plurality of types of symbols is provided. The variable display section 9 has, for example, three symbol display areas of “left”, “middle”, and “right”. Below the variable display section 9, a starting winning port 14 is provided. The winning ball entering the starting winning opening 14 is a game board 6
And detected by a starting port switch (not shown). In addition, a variable winning ball device 15 that performs opening and closing operations is provided below the starting winning port 14. The variable winning ball device 15 is opened by a solenoid (not shown).

An opening / closing plate 20, which is opened by a solenoid (not shown) in a specific game state (big hit state), is provided below the variable winning ball device 15. In this embodiment, the opening and closing plate 20 serves as a means for opening and closing the special winning opening. A winning ball that has entered one (V zone) of the winning balls guided from the opening / closing plate 20 to the back of the game board 6 is detected by a V winning switch (not shown). A winning ball from the opening / closing plate 20 is detected by a count switch (not shown). Below the variable display section 9, a special symbol start storage display 18 having four display sections for displaying the number of winning balls entering the start winning opening 14 is provided. In this example, the special symbol start storage display unit 18 increases the number of lit display units one by one every time there is a start winning, with four as an upper limit. Then, each time the variable display of the variable display unit 9 is started, the number of the lit display units is reduced by one.

The game board 6 has a plurality of winning openings 19, 24,
32, 33 are provided, each of the winning holes 1 of the game ball
Wins to 9, 24, 32 and 33 are detected by correspondingly provided winning opening switches (not shown).
In the lower part of the game area 7, there is an out port 26 for absorbing a hit ball that has not been won.

When the game ball wins the winning opening 32, the variable display of the display of the ordinary symbol display 10 by the 7-segment LED is started. When the stop symbol on the ordinary symbol display 10 is a predetermined symbol (hit symbol), the variable winning ball device 15 is opened for a predetermined time. In the vicinity of the ordinary symbol display 10, an ordinary symbol start storage display 41 having four display sections for displaying the number of winning balls entering the winning opening 32 is provided. In this example, each time there is a prize in the winning opening 32, the normal symbol start storage display 41 increases the number of lit display units one by one, with four as an upper limit. Then, every time the opening of the variable winning prize ball device 15 is started, the number of the lit display unit is reduced by one.

Also, two loudspeakers 2 for emitting sound effects and sounds are provided on the upper right and left glass door frames 2 outside the game area 7.
7 are provided. Glass door frame 2 around game area 7
Are provided with a top frame lamp 28a, a left frame lamp 28b, and a right frame lamp 28c.

In this example, a prize ball lamp 51 is provided near the left frame lamp 28b, which is lit when there is a prize ball remaining to be paid, and when the supply ball is cut near the top frame lamp 28a. Is provided with an out-of-sphere lamp 52 that lights up. Further, FIG. 1 also shows a card unit 50 that is installed adjacent to the pachinko gaming machine 1 and that allows a ball to be lent by inserting a prepaid card.

The card unit 50 has a usable indicator lamp 151 indicating whether the card unit 50 is in a usable state, and a link stand direction indicator indicating which side of the pachinko gaming machine 1 the card unit 50 corresponds to. 153, a card insertion indicator 154 for indicating that a card is inserted into the card unit 50, a card insertion slot 155 for inserting a card as a recording medium, and a card reader provided on the back of the card insertion slot 155.

The metal game ball fired from the hit ball launching device enters the game area 7 through the hit ball rail, and thereafter,
It comes down the game area 7. When the hit ball enters the starting winning opening 14 and is detected by the starting switch 17, the symbols in the variable display section 9 start rotating if the symbols can be changed. If it is not possible to start changing the symbol, the start winning memory is increased by one.

The rotation of the image in the variable display section 9 stops when a certain time has elapsed. If the combination of images at the time of stop is a combination of big hit symbols, the game shifts to a big hit game state. That is, the opening / closing plate 20 is opened until a predetermined time elapses or until a predetermined number (for example, 10) of hit balls is won. When a hit ball wins in the specific winning area while the opening and closing plate 20 is being opened and is detected by the V winning switch, a continuation right is generated and the opening and closing plate 20 is opened again.
Generation of the continuation right is permitted a predetermined number of times (for example, 15 rounds).

If the combination of images in the variable display section 9 at the time of stoppage is a combination of big hit symbols with probability fluctuation, the probability of the next big hit becomes high. That is, a high probability state, which is more advantageous for the player, is obtained.

When the hit ball wins the winning opening 32, the number displayed on the symbol display device 10 normally changes. When the stop symbol on the ordinary symbol display 10 is a predetermined symbol (hit symbol), the variable winning ball device 15
Is open for a predetermined time. Further, in the high probability state, the probability that the stop symbol on the ordinary symbol display 10 hits the symbol is increased, and the opening time and the number of times the variable winning ball device 15 is opened are increased.

FIG. 2 is a front view showing the front of the game board 6 with the glass door frame 2 removed. The metal game ball fired from the launching device travels on a stainless steel firing rail 201, passes over a circumferential stainless steel outer rail 202 installed on the game board 6, and passes through the outer rail 202. And enter the game area 7. The game board 6 is provided with an inner rail 203 made of stainless steel so as to surround the game area 7 together with the outer rail 202. Outer rail 202 and inner rail 2
03 is formed of a conductive member such as stainless steel. Therefore, the outer rail 202 and the inner rail 203 are electrically connected.

A metal plate which is in contact with the outer rail 202 when the glass door frame 2 is closed is provided on the back surface (the game board side) of the glass door frame 2. The stainless steel firing rail 201 is formed in a groove shape, and one wall portion of the groove is in contact with a metal plate installed on the glass door frame 2 in a state where the glass door frame 2 is closed. It has become. Therefore, the firing rail 201 and the outer rail 202
When the glass door frame 2 is closed, it is electrically conductive. Therefore, in the state where the game is played, the firing rail 20
1 and the outer rail 202 and the inner rail 203 are electrically connected.

Further, a connecting portion (for example, a metal fitting provided at an end of the wiring 205) for connecting a wiring (for example, a covered copper wire, the same applies to the following wiring) 205 to a part of the firing rail 201 is screwed. Stop). The wiring 205 is connected directly or via another conductive member to a metal fitting of a mechanism plate described later. As will be described later, the receiving plate of the mechanism plate is grounded directly or through another conductive member. Therefore, the launch rail 201, the outer rail 202, and the inner rail 203 with which the game ball launched from the launch device comes into contact are grounded. Hitting rail (launch rail 201, outer rail 20)
2 and the inner rail 203),
1. Since the potential of the game ball in contact with the outer rail 202 and the inner rail 203 becomes the same as the potential of the firing rail 201, the outer rail 202 and the inner rail 203, the charging of the game ball is prevented. As a result, generation of noise due to discharge is prevented.

Further, a mechanism for preventing charging of the game balls when flowing down the game area 7 may be provided. For example, a conductive member such as a metal plate is laminated below the wood member on the surface of the game board 6, and a large number of nails driven into the game area are brought into contact with the conductive member. Then, by grounding the conductive member, the nail, the hitting rail and the game ball provided in the game area 7 can be set to the same potential. Therefore, the discharge prevention effect is enhanced. Further, the windmill, each winning ball device, the decorative member, and the like provided in the game area 7 may be formed of a conductive synthetic resin.

FIG. 3 is a back view of the gaming machine viewed from the back. FIG. 4 is a rear view of the mechanism plate to which various members are attached as viewed from the rear side of the gaming machine. FIG. 5 is a perspective view of the mechanism plate viewed from an oblique direction on the front side of the gaming machine.

In this embodiment, the base 3 of the mechanism plate
As No. 6, an ABS resin plate containing 6% by weight of stainless steel fiber is used. Therefore, the base 3 of the mechanism plate
6 has conductivity. As shown in FIGS. 3 to 5, on the back surface of the pachinko gaming machine 1, a storage tank 38 is provided above the mechanism plate.
Is provided. Then, in a state where the pachinko gaming machine 1 is installed on the gaming machine installation island, gaming balls are supplied to the storage tank 38 from above. As shown in FIGS. 3 and 4,

Is bent in the middle and further divided into two sections to reach the ball dispensing device.

As the synthetic resin containing stainless steel fiber, a synthetic resin obtained by adding a fine stainless steel fiber having a diameter of 6 to 10 μm as a filler to a synthetic resin as a base can be used. Since ultra-fine stainless fibers are used, it is possible to exhibit conductivity that does not change even with environmental changes in temperature and humidity with a small amount of addition. Naturally, it is also excellent in rust prevention. Various thermoplastic resins can be used as a synthetic resin as a base. When an ABS resin is used as a base and stainless fibers as a filler are added at 6% by weight, an ABS resin containing 6% by weight of stainless fibers can be obtained. If polycarbonate is used as a base, a polycarbonate containing stainless fibers can be obtained.

The synthetic resin containing stainless fibers has higher flame retardancy than a carbon-containing resin using only carbon as a filler. Pachinko machines are often installed in a smoking environment. Further, since there are many electric wires inside the gaming machine or between the gaming machine installation island and the gaming machine, the possibility of fire due to short-circuit or the like cannot be denied. Therefore, using a highly flame-retardant member in a gaming machine further enhances the safety of the gaming machine. Further, the synthetic resin containing stainless fibers has a lower specific resistance than a carbon-containing resin using only carbon as a filler. Accordingly, high conductivity can be obtained, which is effective for preventing the game balls in contact from being charged.

In this embodiment, a prize ball case 40A (cases 140, 141, 142) accommodating a ball payout device.
And the side wall of the ball passage 293 contains 8% by weight of carbon.
It is formed of the contained polycarbonate. Therefore,
The ball passage 293 through which the game ball passes is conductive, and the potential of the ball passage 293 and the potential of the game ball passing therethrough become the same. Also, the side wall of the ball passage 293 and the prize ball case 40
Since A is in contact with the ball, the game ball passing through the ball passage and the prize ball case 40A have the same potential.

Further, as shown in FIG.
At the upper part of 0A, the prize ball case 40A is fixed to the base body 36 of the mechanism plate by a stainless steel press fitting 231. Therefore, the conductive prize ball case 40A
And the stainless steel press fitting 231 are in contact with each other. Further, the holding metal 231 is connected to the
A connection part (for example,
(A structure in which a metal fitting provided at an end of the wiring 214 is screwed) 215
(See FIGS. 4 and 5). Therefore, the potential of the prize ball case 40A becomes the same as the potential of the metal fitting 209. As described above, since the potential of the metal fitting 209 is at the ground level, the potential of the prize ball case 40A is also at the ground level.

In the ball dispensing device, cases 140, 14
1,142 is made of polycarbonate containing 8% by weight of carbon. However, since the material containing carbon has flammability, it is made of synthetic resin containing flame-retardant stainless steel fiber. Is also good. The gear 209,
Since 291 does not come into contact with the game ball, it is formed of a synthetic resin having no conductivity. Also, the sprocket 29
Since the game ball 2 only makes temporary contact with the game ball, it is also formed of a synthetic resin having no conductivity. The reason why polycarbonate is used as the material of the cases 140, 141, 142 instead of ABS resin is that polycarbonate has higher wear resistance than ABS resin.

As described above, in the gaming machine of the above-described embodiment, in the structure in which the payout mechanism for paying out the game medium is installed on the mechanism plate, the members constituting the mechanical section (in the above example, the mechanism Board base body 36 and passage for game balls)
Are formed of a synthetic resin containing stainless steel fibers. Therefore, the flame retardancy of the gaming machine is enhanced, and the effect of preventing the game balls from being charged is also improved. In particular, in the payout mechanism for paying out game media, the ball passage through which the game balls flow is formed of a synthetic resin containing stainless steel fibers, so that the antistatic effect is large.

In the above embodiment, in the payout mechanism for paying out game media, the storage tank 38 and the guide gutter 206 are made of ABS resin containing 8% by weight of carbon, and the prize ball case 40A is made of 8% by weight of carbon. It was made of polycarbonate containing 10% by weight. That is, since the members for storing, guiding, and paying out the game media are formed of conductive synthetic resin, it is possible to ensure conductivity at the contact portions of the game balls without using any metal parts, Antistatic measures can be taken.

Further, in the member made of carbon-containing synthetic resin such as the storage tank 38, the guide gutter 206, and the prize ball case 40A, the connecting portions 212 and 2
23 as a metal member provided as a metal member provided in contact with the carbon-containing synthetic resin.
Since connection portions for connecting wires are provided at 31 and the like, wiring work for grounding a member made of a carbon-containing synthetic resin is easy.

The storage tank 38, which is a part of the contact portion of the game medium in the mechanism, and the ball passage 2 in the ball payout device
Although the carbon-containing synthetic resin is used for 93 and the guide gutter 206, a synthetic resin containing stainless steel fiber may be used for them.

In the above-described embodiment, a part of the members constituting the mechanism is formed of the stainless-containing synthetic resin. However, all the members constituting the mechanism may be formed of the stainless-containing synthetic resin. Good.

FIG. 8 shows an antistatic effect (static electricity removing effect).
FIG. 3 is an explanatory diagram for explaining the method. FIG. 8A shows a conventional example in which a carbon-containing synthetic resin 400 containing carbon 403 is used in a passage of a game ball 401 and the carbon-containing synthetic resin 400 is grounded. The specific resistance of the carbon-containing resin 400 is generally as high as about 10 ⁵ to 10 ⁷ Ω · cm, and the conductivity is not high. Therefore, when the game ball 401 is charged, the degree of charge transfer to the carbon-containing resin 400 and the degree of charge transfer to the ground plate 402 are relatively small. That is, the discharge effect when the game ball 401 is charged is smaller than that in the case shown in FIG.

FIG. 8B shows an example in which a synthetic resin containing a stainless fiber 413 (stainless steel-containing synthetic resin 410) is used. The specific resistance of the stainless-containing synthetic resin 410 is much smaller than the specific resistance of the carbon-containing synthetic resin 400, and the same level of charge absorption performance as when a metal plate is embedded in the synthetic resin can be expected. Also,
The effect of preventing generation of static electricity can be expected to the same extent as when a metal plate is embedded in a synthetic resin. That is, a higher antistatic effect is achieved as compared with the case where the carbon-containing synthetic resin 400 is used.

When the synthetic resin contains only stainless steel fibers, the contact of the stainless fibers may be weakened due to thermal deformation of the synthetic resin itself, and the conductivity may be reduced. It has been reported. In order to eliminate such a possibility, a stainless steel-containing synthetic resin further containing carbon may be used. That is,
The member constituting the mechanism may be formed of a synthetic resin containing stainless steel fiber and carbon. Also, even when the synthetic resin contains only stainless steel fibers, such a synthetic resin shows high shielding properties,
When carbon is further contained, the shielding effect does not decrease even in an environment where high and low temperatures are repeated.

FIG. 9 is a wiring diagram showing the components mounted on the mechanism plate 36 together with the ball hitting rail, the payout control board 37 and the card unit 50. As described above, the hitting rails (the firing rail 201, the outer rail 202, and the inner rail 203) are made of stainless steel, and the firing rail 201, the outer rail 202, and the inner rail 203 are electrically connected when a game is played. It is conducting.

The guide gutter 206 is formed of an ABS resin containing 8% by weight of carbon, and the ground gutter 206 is in contact with the guide gutter 206. The firing rail 201 and the guide gutter 206 are connected by a wiring 205. Further, the guide gutter 206 is connected by a wiring 224 to a receiving fitting 222 connected to a fitting 209 of the mechanism plate. Hardware 20
9 and the receiving fitting 222 are made of stainless steel. Therefore, the potential of the hitting rail and the guiding gutter 206 is
It is the same as the potential of the metal fitting 209 of the mechanism plate.

The storage tank 38 is formed of an ABS resin containing 8% by weight of carbon, and a part thereof is provided with an earth plate 218. The storage tank 38 is connected to a metal plate 209 of the mechanism plate by a wiring 211. Therefore, the potential of the storage tank 38 is controlled by the metal plate 2 of the mechanism plate.
09 and the same potential.

The prize ball case 40A is made of polycarbonate containing 8% by weight of carbon. A stainless steel holding member 231 is in contact with the prize ball case 40A. Further, the holding member 231 is connected to the metal plate 209 of the mechanism plate by the wiring 214. Therefore, the potential of the prize ball case 40A is the same as the potential of the metal plate 209 of the mechanism plate.

Accordingly, a ball hitting rail serving as a path for game balls fired from the firing device, a storage tank 38 serving as a main portion of a path for game balls to be dispensed, and a ball passage 29 in the ball dispensing device.
The electric potential of 3 and the guide gutter 206 is the same as the electric potential of the metal plate 209 of the mechanical plate and the base body 36 of the mechanical plate to which the metal plate 209 is attached. The metal fitting 209 is grounded via the payout control board 37 and the card unit 50. Therefore, the potentials of the hitting rail, the storage tank 38, the ball passage 293 in the ball dispensing device, the guide gutter 206, and the base body 36 of the mechanism plate are at the ground level.

As clearly shown in FIG. 9, a conductive synthetic resin member is used at a position where the game medium can be contacted (in the above example, the storage tank 38, the guide gutter 209, etc.). The resin member is indirectly grounded. As a conventional countermeasure against static electricity noise, there has been a method of providing a metal ground plate at a position in contact with a game medium, but according to such a method, a charged game ball is rapidly discharged when it comes into contact with the ground plate. As a result, there is a possibility that electromagnetic interference as static noise is given to an electronic circuit in a control board installed in the gaming machine. However, if the conductive synthetic resin member is arranged at a position where the conductive synthetic resin member can be contacted with the game medium as in the above embodiment, the occurrence of sudden discharge is reduced, and the electronic circuit in the control board is reduced. The possibility of causing electromagnetic interference is eliminated. For example, the carbon-containing synthetic resin has a specific resistance of about 10 ⁵ to 10 ⁷ Ω · cm, which is larger than that of a metal, so that a sudden discharge does not occur.

However, a metal plate (earth plate) 218 as a metal member is provided at a position where a metal plate (earth plate) 218 as a metal member contacts a part of the storage tank 38 and is in contact with the guide gutter 206. . Therefore, the degree of charge transfer from the charged game balls (static electricity removing effect) is further increased while preventing abrupt discharge between the game balls. That is, the antistatic effect of the game ball is higher than the case where only the conductive synthetic resin member is used for the storage tank 38 and the guide gutter 209. In addition, the metal plates 218 and 221 are
Even if it is not in direct contact with the storage tank 38 or the guide gutter 206, the above-mentioned effects can be obtained as long as they are electrically connected to them.

The conductive synthetic resin member and the grounding portion are electrically connected between the storage tank 38 made of the conductive synthetic resin member, the prize ball case 40A and the guiding gutter 206 and the grounding portion (grounding of the card unit 50). A metal fitting 209 that can be electrically connected is interposed. That is, wiring may be applied to the metal fittings 209 installed relatively close to each conductive synthetic resin member, and one system of wiring may be extended from the metal fittings 209 to the grounding point. Therefore, the wiring for grounding is easier than when each conductive synthetic resin member is directly grounded.

Further, in the gaming machine, not only the mechanism but also the hit ball supply tray (upper plate) 3 and the surplus ball tray (lower plate) 4
The passage portion of the game medium in the gaming machine including the above may be formed of a synthetic resin containing stainless steel fiber. That is,
In the gaming machine, a storage tank 38 for supplying game balls from outside the gaming machine, a mechanism, and a hit ball supply tray (upper plate) 3 for storing game balls paid out to the player and a surplus ball tray (lower plate) 4 may be formed of a synthetic resin containing stainless steel fibers. Also, even if a part of the passage portion of such a game ball is formed of a synthetic resin containing stainless steel fibers, the degree of difference is different from the case where all of the passage portions are formed of a synthetic resin containing stainless steel fibers. However, it can exert the static electricity removing effect. Further, in the gaming machine, all parts that can be brought into contact with the game balls, including the components (such as the winning device and the decorative member) provided on the game board 6, may be formed of a synthetic resin containing stainless steel fibers.

In the above embodiment, the storage tank 38, the guide gutter 206, and the prize ball case 40A of the payout device are used as the conductive synthetic resin members arranged at positions where they can come into contact with the game balls.
However, other game ball contact portions in the gaming machine are formed of a conductive synthetic resin member made of a conductive synthetic resin, and the conductive synthetic resin member is electrically grounded. May be. The conductive synthetic resin member may be a synthetic resin member containing carbon,
Any material having conductivity such as a synthetic resin containing a metal may be used. Furthermore, as the predetermined portion where the conductive synthetic resin member is disposed, a position where the conductive synthetic resin member can be brought into contact with the game ball has been exemplified. Good. For example, a metal or other highly conductive member may be arranged at a position where the member can contact the game ball, and a conductive synthetic resin member may be arranged between such a member and the ground.

As an example of using a carbon-containing conductive synthetic resin member and a metal-containing conductive synthetic resin member together, a storage tank 38 provided in a mechanism section, a guide gutter 206 and a prize ball of a dispensing device are used. Case 40A (conductive synthetic resin member containing carbon) and base body 3 of mechanism plate
8 (a conductive synthetic resin member containing a metal) has been described, but the combined use of a conductive synthetic resin member containing a carbon and a conductive synthetic resin member containing a metal can be applied to such a member in the mechanism section. The present invention is not limited thereto, and the present invention can be applied to other portions of the gaming machine that can contact the game balls. For example, a conductive synthetic resin member containing metal may be used for the hit ball supply tray (upper tray) 3 and the surplus ball tray (lower tray) 4.

Further, in the above embodiment, the synthetic resin containing stainless steel as a filler is used as the synthetic resin containing stainless steel, but the synthetic resin containing flake-like stainless steel is used as the filler. Is also good.
