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 player plays a predetermined game using game media, and more particularly to a game machine having a passage through which game media can pass.

[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 passage portion of the gaming ball is realized by a synthetic resin material.

[0005] Then, there is a possibility that the game balls are charged by friction or the like between the game balls and the passage portion, 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.

In order to eliminate such inconveniences, a portion of the passage portion of the game ball that can be contacted by the game ball is formed of a conductive material such as a metal or a synthetic resin having conductivity (conductive synthetic resin). Has also been done. That is, there are cases where a portion that can be contacted with a game ball, such as a base body of the mechanism portion or a dish storage portion provided on the front of the gaming machine, is formed of a conductive material.

For example, as shown in FIG. 10, two convex portions are provided on a base body 30A of a mechanism portion, and a lid portion 302 is formed so as to close a space formed by the two convex portions on the base body 30A.
There is a structure provided with. The space formed by the two convex portions and the lid portion 302 in the base body 30A becomes a passage through which the game ball 400 flows. Then, in order to form the passage portion with a conductive material, the base body 30A and the lid 302 are formed with a conductive material.

Further, as shown in FIG. 11, there is also a structure in which a passage member 310A having a shelf-shaped cross section is fixed to a base body 30A of a mechanism section formed of a conductive material with screws 303 or the like. One open space formed by the base body 30A and the passage member 310A becomes a passage through which the gaming ball 400 flows. Then, in order to form the passage portion with a conductive material, the base body 30A and the passage member 310A are formed with a conductive material. According to the configuration illustrated in FIGS. 10 and 11, the charge amount of the game ball can be reduced as compared with the case where the passage portion of the game ball is formed of a non-conductive synthetic resin.

[0009]

However, conductive materials are generally more expensive than non-conductive synthetic resins. Therefore, if the passage portion of the game ball including the base body of the mechanism section is formed of a conductive material, the cost of the game machine increases. As a result, the price of the gaming machine increases.

Accordingly, an object of the present invention is to provide a gaming machine for playing a game using a gaming medium, which can prevent the gaming medium from being charged in a passage portion without increasing the cost. I do.

[0011]

A gaming machine according to the present invention comprises:
A game machine in which a player performs a predetermined game using a game medium, wherein at least a part of passages through which the game medium can pass can be attached to the base as a separate member from the base.

Wherein the base is made of a non-conductive material and the passage member is made of a conductive synthetic resin.

The synthetic resin having conductivity is, for example, a synthetic resin containing carbon.

The synthetic resin having conductivity may be a synthetic resin containing a stainless filler.

The synthetic resin having conductivity may be a synthetic resin containing a fibrous conductive substance.

[0017] At least a part of the passage of the game medium in the mechanism portion having the mechanism for paying out the game medium is formed as a passage member.

The passage member made of a conductive material is applied, for example, to a passage for guiding a game medium from a storage tank for storing the game medium.

The passage member made of a conductive material is applied, for example, to a passage for guiding a game medium to a payout device for paying out a game medium.

The passage member made of a conductive material is applied, for example, to a passage for changing the guiding direction of a game medium.

The passage member made of a conductive material is applied to, for example, a passage for guiding a game medium to a storage portion provided on the front surface of a game machine and for storing a paid-out game medium.

The passage member made of a conductive material is used, for example, for a second storage portion provided separately from the first storage portion on the front surface of the gaming machine, and for a game medium paid out to the first storage portion. Is applied to a path for guiding surplus game media from a path for guiding the game media.

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 stop is a combination of big hit symbols with probability fluctuation, the probability of the next big hit increases. 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 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.

A guidance unit 194 is provided. Game ball guiding unit 19
Reference numeral 4 is formed as a single member of a conductive synthetic resin, and attached to the base body 30 of the mechanism section 36 with screws or the like. A member to which each member forming the passage portion of the game ball is attached (for example, the base body 30 of the mechanism portion 36) is referred to as a base. Further, in this embodiment, the passage of a plurality of game balls is realized by one game ball guiding section 194, but the members for realizing each passage may be separated.

Further, the game ball guiding section 194 includes a lid 19.
5 are closely adhered to each other to form a closed space that becomes a passage of the game ball. The cover 195 is formed as a single member from a conductive synthetic resin, and is attached to the base body 30 with screws or the like. The lid 195 also functions as a base of the payout control board 37.

As described above, in this embodiment, the base such as the base body 30 of the mechanism 36 to which each member forming the passage portion of the game ball is attached is formed of a non-conductive material. In addition, the guide rail 39, the curve gutter 186, the vertical passage 188, the prize ball case 40A, the ball removing portion 190, the ball removing passage 191, the game ball guiding portion 194, and the cover portion 195, which are members forming the passage portion of the game ball, are provided. Are formed as separate members, and are attached to the base.

Unlike the conventional example shown in FIGS. 10 and 11, the base such as the base body 30 is formed of a non-conductive material. It is preferable to adopt a structure that does not come into contact with a base such as the body 30. Therefore, it is preferable that each member forming the passage portion of the game ball has a structure in which four sides can be inscribed in the game ball as shown in FIG. 7, for example. FIG. 7 shows a passage member 301 forming a space through which a game ball passes and a lid 30 closing the space as members forming a passage portion of the game ball.
2 is shown. The passage member 301 and the lid 302 are formed of a conductive synthetic resin.
Reference numeral 1 denotes a screw 303 or the like, which is attached to the non-conductive base body 30.

As shown in FIG. 8, there is also a structure in which a passage member 310 having a concave cross section is fixed to the non-conductive base body 30 with a screw 303 or the like. One open space formed by the passage member 310 is a passage through which the gaming ball 400 flows. The passage member 310 is formed of a conductive synthetic resin.

Further, as shown in FIG. 9, a non-conductive material in which a concave conductive member (for example, a metal plate) 322 is adhered to the inner wall of a gutter-shaped (concave) member 321 is used as a base 30 or the like. An internal space may be formed by attaching to the base, and a conductive member (for example, a metal plate) 323 may be provided on the internal space side of the base such as the base body 30 to form a passage member. Even with such a configuration, a passage member made of a conductive material can be formed in the game ball passage portion. When the passage is formed of a conductive material, the material is opaque and it is difficult to recognize whether or not there is a game ball in the passage. It is desirable to make it possible.

Since the base such as the base body 30 in the mechanism section 36 is formed of a synthetic resin having no conductivity, the cost of the mechanism section 36 is lower than when the base is formed of a conductive material. Further, since each member forming the passage portion of the game ball is formed of a conductive synthetic resin, the effect of preventing the game ball from being charged is not reduced. Further, each member forming the passage portion of the game ball is a rigid member. That is, it is not a flexible tubular member such as a metal bellows hose, but a non-flexible (non-flexible) member. Since each member is inflexible, it is easy to attach each member to the base, and it is also easy to position each member when each member is formed as a separate member.

In the above-described embodiment, an example has been shown in which all the members forming the passage portion of the game ball are formed as separate members of conductive synthetic resin. Even if it is formed as a separate member of a synthetic resin, the antistatic effect of the game ball can be exhibited. In the case where only some of the members are formed of the conductive synthetic resin, the cost is reduced as compared with the case where all the members are formed of the conductive synthetic resin.
Further, as the conductive synthetic resin, for example, a synthetic resin containing powdered or fibrous carbon can be used.
Further, a combination of a plurality of members forming the passage portion of the game ball used in the above embodiment may be attached to the base as one member. At this time, all of the portions constituting one member may be formed of a conductive synthetic resin, or some of the portions may be formed of a conductive synthetic resin.

Not limited to the mechanism section 36, each member forming the passage portion of the game ball may be formed of a conductive synthetic resin. For example, an upper plate (first storage unit) 3 that stores the paid out game balls while moving them in accordance with the hit ball firing, and a lower plate that stores excess game balls from a passage for guiding the game balls to the upper plate 3. (Second storage unit) 4, a portion through which game balls pass, such as a guiding gutter 206 that guides the paid game balls to the upper plate 3, may be formed of a conductive synthetic resin.

Each member forming the passage portion of the game ball may be formed of a metal material (various alloys such as stainless steel and magnesium alloy) instead of the conductive synthetic resin. Further, it may be formed of a material made by plating or applying a metal to a synthetic resin having no conductivity.

As the conductive synthetic resin, a synthetic resin such as an ABS resin containing, for example, 6% by weight of stainless fibers can be used. As a synthetic resin containing a 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. Of course,
Excellent 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 the 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.

It has been reported that when only stainless steel fibers are contained in the synthetic resin, there is a possibility that the contact of the stainless fibers is weakened due to thermal deformation of the synthetic resin itself and the conductivity is reduced. ing. In order to eliminate such a possibility, a stainless steel-containing synthetic resin further containing carbon may be used. That is, the members constituting the mechanism may be formed of a synthetic resin containing stainless steel fiber and carbon.

The passage member made of a conductive material may be grounded. In that case, the passage member can be grounded, for example, by connecting a lead wire reaching the grounding point to the passage member. Further, since the card unit 50 is generally grounded via a ground wire, when the card unit 50 is provided, a necessary grounding point on the gaming machine side is connected to an FG (frame ground) terminal of the card unit 50. If connected, the passage member on the gaming machine side can be easily grounded. Further, in the case where a plurality of passage members made of a conductive material are provided, they are brought to the same potential when they are conducted to each other, so that it is possible to more effectively prevent charging.

Further, in the pachinko gaming machine 1 of each of the above-described embodiments, when the stop symbol of the special symbol variably displayed on the variable display section 9 based on the winning start becomes a predetermined symbol combination, the predetermined game value is reduced. Although it was a first-class pachinko gaming machine that can be given to a player, a predetermined game value that can be given to a player when there is a prize in a predetermined area of an electric accessory that is opened based on a start winning prize. Two types of pachinko machines,
A third-type pachinko gaming machine in which a predetermined right is generated or continued when there is a prize in a predetermined electric accessory which is opened when a stop symbol of a symbol variably displayed based on a start winning prize is a predetermined combination of symbols. Even so, the present invention can be applied.

The present invention is not limited to the pachinko gaming machine, but can be applied to a slot machine or the like when a payout mechanism for paying out game media is provided.
