Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko game machine, and more particularly, to a game machine having a game board provided with members such as an obstacle nail and an accessory for forming a falling path of a game ball. Things.

[0002]

2. Description of the Related Art Conventionally, as one form of pachinko gaming machines,
2. Description of the Related Art It is known that a game board is provided with a display device, a winning device, an obstacle nail, a windmill, and the like. In this pachinko machine, a game ball fired by a player's operation and guided to the upper part of the game board hits an obstacle nail or the like in a falling process,
The falling speed is suppressed or the traveling direction is changed. Then, when the game ball wins the starting port, which is one of the winning devices, for example, the symbol on the display device starts to change. If the symbol combination displayed on the display device after the symbol change has stopped after the reach game state is a predetermined jackpot combination, that is, if the lottery is "big hit", the big hit A gaming state occurs. In this state, for example, a special winning opening, which is one of the winning devices, is opened, so that the game balls can easily enter the special winning opening, and the player can acquire more winning balls.

[0003] By the way, in pachinko gaming machines, even if a new model of game contents is developed and provided to the market, it is often replaced with a new model in a relatively short period of time because the game contents become tired. In this case, the pachinko game machine, especially the game board, is collected from the market and changed to a new game content. The same applies to a case where a game board or the like has been worn out or has failed. On the other hand, the components that make up the game board are made of various materials such as wood, synthetic resin, rubber, and metal. After being removed, they are sorted by material and recycled (recycled)
Or be disposed of.

Whether each component is subject to disposal,
Alternatively, whether or not to be recycled is determined according to criteria such as whether or not it is suitable for disposal, that is, whether or not deterioration or corrosion is likely to occur. For example, if the game console body is made of wood, it will be decomposed by microorganisms and will decay if exposed to the weather or buried in the soil, and will not remain in its original form. It is said. When the display device, the winning device, etc. are formed of synthetic resin, and when the obstacle nails, windmills, etc. are formed of metal, their components may deteriorate or corrode over a long period of time. Because it is not suitable for disposal, it is subject to recycling.

[0005] In particular, PC (polycarbonate), ABS
(Acrylonitrile-butadiene-styrene copolymer)
And other general-purpose synthetic resins are difficult to decompose and are not decomposed by microorganisms at all, or are decomposed very slowly. It is also a very chemically stable compound.
Therefore, it is not particularly suitable for disposal. A method of incinerating parts made of these synthetic resins is also conceivable.However, this may be a desirable treatment method because it may generate high temperatures due to combustion and damage the incinerator or generate toxic gas. Absent.

[0006]

When the above-mentioned components of the game board are recycled, the display device and the winning device are usually fastened to the game board body at several places by fastening parts such as screws. If these fasteners are loosened and removed, the display device and the like can be relatively easily removed. However, since obstacle nails and pinwheel nails are driven into the game board main body, it is not easy to remove them. In addition, since the number of obstacle nails is large unlike a prize-winning device or the like, it takes a great deal of time (time and labor) to remove all the obstacle nails, which leads to a reduction in collection workability. as a result,
In some cases, the game board is discarded without being disassembled, that is, it contains parts that are difficult to biodegrade, and the fact is that recycling is not sufficiently performed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gaming machine which can reduce the work of removing a component that is not suitable for disposal from a game board and can promote the recycling while eliminating the problem of disposal. is there.

According to the means 1, during operation of the gaming machine,
The frequency at which the game balls fall on the fall path formed by the second path constituent part is lower than the frequency of falling on the fall path formed by the first path constituent part. Therefore, the frequency at which the game ball hits the second route component is low, and the impact applied to the second route component is smaller than the impact applied to the first route component. For this reason, even if the strength of the portion formed of the biodegradable material in the main part of the second path component is lower than the strength of the first path component, wear caused by contact with the game ball, Damage is unlikely to occur.

Incidentally, in the game board, a portion formed of a biodegradable material in a main portion of the second path constituting portion can be a target of disposal. This is because when this portion is discarded, it is decomposed by microorganisms. In addition, since this part is originally provided on the game board main body so as to be difficult to attach and detach, if it is supposed to be removed,
It is also a place where it takes time to remove. Therefore, by being subject to disposal, the number of components to be removed among the components of the game board is reduced. In addition, there is no need to remove at least a part of the main part of the second path component, which would otherwise be troublesome.

According to the means 4, the game ball fired in response to the operation of the shooting handle by the player and guided to the upper portion of the game board main body firstly strikes the first path constituting portion. The game ball may then pass through the fall path formed by the first path component and hit the second path component formed by the biodegradable material at the lower portion of the left region. Since the momentum of the game ball when hitting the second path component is usually weaker than the momentum when guided to the upper part of the game board main body, the second path component is brought into contact with the game ball. Is applied to the top of the game board.
It is smaller than the impact applied to the path component. The portion made of this biodegradable material is unlikely to cause abrasion, breakage and the like despite contact with the game ball.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1 (a) to 1 (c). The gaming board 1 is incorporated in the pachinko gaming machine. A part of the game board 1 is constituted by a game board body 2 made of a synthetic resin. Most of the game board main body 2 is formed to be thinner than that made of conventional wood. A game area 4 is defined by the guide rail 3 in the game board main body 2. The guide rail 3 is for guiding a game ball 5 as a game medium fired from a firing device (not shown) to an upper portion of the game area 4 in response to an operation of a firing handle by a player.

Openings (not shown) are provided at a plurality of places corresponding to the game area 4 of the game board main body 2, and the general winning opening 6, the starting opening 7, the large winning opening 8, and the gate 9 are formed in these openings. , Special symbol display device (hereinafter simply referred to as "display device")
Accessories such as 11 and a side lamp 12 are detachably mounted by a locking mechanism (not shown). Each accessory is composed of a plurality of parts, at least some of which are P
It is formed of a general-purpose synthetic resin such as C or ABS.
The locking mechanism is not particularly limited, but preferably has a structure that can be attached and detached by a simple operation. For example, in the case of the display device 11, an elastic piece provided on the frame and having a claw portion at the tip and a locked portion provided near the opening of the game board main body 2 and locked by the claw portion are provided. Combinations are included. In this locking mechanism, when a part of the frame of the display device 11 is inserted into the opening, the claw portion is engaged with the locked portion, and the display device 11 is mounted on the game board main body 2. When the display device 11 is strongly pulled forward from this state, the claw portion comes off the locked portion, and the display device 11 can be pulled out from the opening.

In addition, in the area on the left side of the game area 4 except for the lower left area, that is, most of the area on the left side and the upper part in the area on the right side, the direction of the drop of the game ball 5 is changed. In addition, an obstacle nail 13, a windmill 14, and a ramp windmill 15 are provided. The obstruction nail 13 is formed of a metal like the obstruction nail implanted in the conventional pachinko game machine, and has high strength. The lamp windmill 15 is a kind of accessory, and, like the display device 11 and the like, is supported rotatably on the base plate by a base plate detachably attached to the game board main body 2 by a locking mechanism and a shaft. It has a disk and a lamp. The windmill 14 is a game board body 2
Metal nails (hereinafter referred to as "windmill nails") 16
And a disk 17 rotatably supported by the windmill nail 16.

As shown in FIG. 1B, holes 18 are provided at a plurality of locations on the game board main body 2 for planting the obstacle nails 13 and the windmill nails 16. A boss 19 is provided around the hole 18 on the rear surface of the game board main body 2 (the left side surface in FIG. 1B).
Is protruding. The boss 19 has a cylindrical shape and is formed integrally with the game board main body 2. Obstacle nail 13 (or windmill nail 1
6) is driven into the hole 18 from the front side of the game board main body 2 and enters the inside of the boss 19, making it difficult to attach / detach.
A cut 19a is formed at the base of the boss 19, that is, at the boundary with the game board main body 2. In addition, in order to increase the strength of the part of the obstacle nail 13 which hits the game ball 5 strongly (the one located at the upper part of the game area 4), it is formed in an annular shape with synthetic resin or the like. Reinforced member 20 is attached.

As shown in FIG. 1 (a), a part of the game ball 5 guided to the upper part of the game area 4 falls in the process of falling, and the obstacle nail 13, the ramp windmill 15, the windmill 14, etc. The direction of the fall is changed. In the present embodiment, the obstacle nail 13, the windmill 14, the ramp windmill 15, and the like constitute a first path component for forming a falling path 21 with a high frequency of passing the game balls 5 on the board surface of the game board body 2. ing. Among these, the obstacle nail 13 and the windmill nail 16 are, in particular,
It constitutes the main part of the first path component.

In the lower left area of the left area of the game area 4 and the parts except the upper area (center and lower parts) of the right area, the ramp windmill 22 is used to change the direction in which the game balls 5 fall. , An obstacle projection 23 and a windmill 25 are provided. The lamp windmill 22 is a lamp windmill 1 described above.
5 has a similar structure. The windmill 25 has substantially the same structure as the windmill 14 described above, but differs in that the components are formed of synthetic resin.

The obstacle protrusion 23 replaces the obstacle nail provided at the corresponding position in the conventional pachinko game machine, and is made of the same kind of synthetic resin as the game board main body 2 and made of a general material such as injection molding. It is formed integrally with the game board main body 2 by a conventional resin molding method, and is not removable. Here, in general, the obstacle nails are arranged at intervals larger than the diameter of the game ball 5 to enable passage thereof, and the obstacle nails are arranged at intervals smaller than the diameter of the game ball 5 to allow passage thereof. Some are made impossible. In order not to impair the function of these two arrangements, the obstruction protrusion 23 is formed in a shape that just connects the latter obstruction nail. The adjacent obstacle protrusions 23 are separated by a width that allows the game balls 5 to pass.

A part of the game ball 5 guided to the upper part of the game area 4 falls on the ramp windmill 22, the obstacle projection 23,
It hits the windmill 25 or the like, and its falling direction is changed. In the present embodiment, the lamp windmill 22 and the obstacle projection 2
3. The windmill 25 and the like constitute a second path component for forming a falling path 24 with a low passing frequency of the game balls 5 on the board surface of the game board main body 2. Among these, the obstacle projection 23
Is a main part of the second path constituting unit.

Although it has already been described that the game board main body 2 and the obstacle projection 23 are made of the same kind of synthetic resin, in the present embodiment, the synthetic resin is a biodegradable material which is a kind of biodegradable material. Resin is used. Biodegradability refers to a property in which a material is decomposed into low molecular compounds that can be metabolized by living organisms, and eventually returns to an ecosystem in an advanced oxidation state such as carbon dioxide and water.

Biodegradable resins are broadly classified into three types: (1) those produced by microorganisms, (2) those made from plants, animals, etc., and (3) chemically synthesized ones. Examples of (1) include a copolymer of polyhydroxybutyrate and valerate, cellulose, pullulan, curdlan and the like. As (2), for example, a mixture with modified polyvinyl alcohol containing starch as a main component, chitosan,
Cellulose and the like can be mentioned. As (3), for example,
Examples thereof include polybutylene succinate, polyethylene succinate, polylactic acid, polycaprolactone, polyglycolic acid, polyvinyl alcohol, polyamino acid, polyurethane, and polyamide oligomer. When a biodegradable resin is selected from these, the resin has such strength as not to cause deformation, breakage, and the like due to contact with the game ball 5, and has excellent workability (formability). It is desirable to consider this.

During operation of the pachinko gaming machine having the gaming board 1 configured as described above, the game ball fired in response to the operation of the shooting handle by the player is moved above the game area 4 by the guide rail 3. Led to the structure located there. At this position, an obstacle nail 13 which is a part of the main part of the first path component is implanted. The strength of the obstacle nail 13 formed of metal is higher than the strength of the obstacle protrusion 23 formed of biodegradable resin. Therefore, even if a relatively large impact is applied due to the contact of the game ball 5, the obstacle nail 13 does not bend or break.

Subsequently, the game balls 5 fall through a left area or a right area of the game area 4. On this occasion,
If a general player performs a general operation on the firing handle, the frequency of the game balls 5 passing through the right area is lower than the frequency passing through the left area. Therefore, the frequency with which the game ball 5 hits the obstacle protrusion 23 located in the right area is low,
The impact applied to the obstruction protrusion 23 is smaller than the impact applied to the obstruction nail 13 and the windmill 14 on the falling path 21 having a high passing frequency. For this reason, even if the strength of the obstacle protrusion 23 formed of the biodegradable material is lower than the strength of the obstacle nail 13 or the windmill 14, the obstacle protrusion 23 is large due to the contact with the game ball 5. There is no risk of wear, breakage or chipping.

The game ball 5 hitting the obstacle nail 13 on the upper part of the game area 4 and entering the left area may hit the obstacle protrusion 23 on the lower left in the process of dropping. The momentum of the falling of the game ball 5 at this time is generally weaker than the momentum when the game ball 5 is guided to the upper part of the game area 4 by the guide rail 3. For this reason, the impact applied to the obstacle projection 23 at the lower left due to the contact with the game ball 5 is smaller than the impact applied to the obstacle nail 13 at the upper part of the game area. The obstacle protrusion 23 made of a biodegradable resin hardly causes abrasion or breakage regardless of contact with the game ball 5.

By the way, when disposing of the game board 1 in accordance with the model change of the pachinko game machine, the portion formed of the biodegradable resin, that is, the game board main body 2 and the obstacle projection 23 can be discarded. . This is because these are decomposed by microorganisms when discarded. The obstruction nail 13 and the windmill nail 16 of the first path component formed of metal are not easily deteriorated or corroded, and are not suitable for disposal. Further, the obstacle protrusion 23 corresponds to a part of an obstacle nail in a conventional pachinko gaming machine. Since the obstacle nail is hard to be attached and detached because it is driven into the game board main body, it is troublesome to remove if it is an object to be removed. Therefore, as described above, since the obstacle projection 23 is to be disposed of, the number of components to be removed among the components of the game board is reduced. In addition, the work of removing the main part (protruding part) of the second path component, which would otherwise be troublesome, becomes unnecessary. The work of removing the component parts that are not suitable for disposal from the game board body 2 is greatly reduced as compared with the related art.

The obstruction nail 13 and the windmill 14 are removed from the game board main body 2 by, for example, being removed, and the locking state by the locking mechanism is released to open the general winning opening 6, the starting opening 7, the large winning opening 8, and the display. If the device 11, the side lamps 12, the lamp windmill 15, and the like are removed from the game board main body 2, the game board main body 2 having the obstruction projections 23 and other components (accessories, etc.) are separated. This makes it easier to separate components that are suitable for disposal from those that are not.
Since the game board main body 2 and the obstacle protruding portion 23 are formed of a biodegradable resin, if they are left or disposed of by landfilling, they are biodegraded by microorganisms in a short period of time, and finally water and It becomes carbon dioxide. Unlike general-purpose synthetic resins that remain intact while remaining in their original form, they do not cause problems such as environmental destruction and contamination. In addition, various accessories including the removed display device 11 can be recycled. As described above, according to the present embodiment, it is possible to reduce the work of removing components that are not suitable for disposal from the game board 1 while avoiding problems such as breakage of the obstacle protrusion 23 caused by contact with the game balls 5. The gaming board 1 can be reliably separated into parts suitable for disposal and parts not suitable for disposal. Therefore, the problem of disposal can be solved and recycling can be promoted.

This embodiment has the following features in addition to the items described above. (A) The game board main body 2 and the obstacle protrusions 23 are formed at once (in a short time) and easily according to a general resin molding method such as injection molding. Post-processing such as separately forming the game board main body 2 and the obstacle protruding portion 23 and connecting them is unnecessary, and the productivity is high. Since it is possible to mold even a complicated shape, only necessary portions (planting portions) are made sufficiently thick to secure the holding strength of the obstacle nails 13 and the like, and the other portions are thinned. The weight can be reduced.

(B) A boss 19 provided on the rear surface of the game board main body 2 at a position corresponding to the planting portion of the obstacle nail 13 and the windmill nail 16 surrounds the obstacle nail 13 and the like and increases the wall thickness. Thereby, the strength of the place where the obstacle nail 13 or the like is planted is supplemented. For this reason, although the game board main body 2 is formed of a synthetic resin, even if the obstacle nail 13 or the like is driven in or the inclination is adjusted, the game board main body 2 is not easily cracked or broken. The boss 19 also has an effect of making it difficult for the obstacle nail 13 and the like to come off from the game board main body 2.

(C) Since the obstacle nail 13 is used as a main part of the first path component, the inclination can be adjusted in the same manner as in the conventional pachinko game machine. This is not possible if the first route component is configured similarly to the second route component (formation of the failure projection 23).

(D) When removing the obstacle nail 13 and the windmill nail 16 from the game board main body 2, the boss 19 is folded at the base 19a at the rear side of the game board 1 at the rear side of the game board 1, and the like. Separate from the main body 2. Then, boss 19 until then
The tip of the obstacle nail 13 or the like that has entered inside appears.
If the front end portion is hit from the rear side of the game board 1 or the like, the obstacle nail 13 or the like is pushed forward and loosened, so that the obstacle nail 13 or the like can be relatively easily removed from the game board body 2.

The present invention can be embodied in another embodiment described below. (1) The material may be displayed on at least one of the components of the game board 1. Further, in place of or in addition to the material, the suitability of disposal, the suitability of recycling, the suitability of incineration, and the like may be displayed. In this way, each component can be easily separated for each material.

(2) The present invention can be applied to a pachinko game machine of a type different from the above-described embodiment.
The present invention can be applied to other types of gaming machines that use a game ball as a game medium.

(3) It is sufficient that at least a part of the main part of the second path constituting part is formed of a biodegradable resin. Therefore, the whole may be formed of a biodegradable resin.

(4) The obstacle nail 13 and the windmill nail 16 may be implanted in a structure different from the above embodiment. For example, there is a structure in which a male screw is formed on the outer circumference of the obstacle nail 13 or the like and screwed into a hole of the game board main body 2.

(5) The game board main body 2 and the obstacle projection 23 may be separately formed, and the obstacle projection 23 may be attached to the game board main body 2 in a difficult-to-remove manner. In this case, many obstacle projections 2
3 may be blocked.

(6) It has already been described that the accessory such as the general winning opening 6, the starting opening 7, the big winning opening 8, the gate 9, the display device 11, and the side lamp 12 is composed of a plurality of parts. At least a part of the component may be formed of a biodegradable resin. In this case, among the component parts of each accessory, those formed of the biodegradable resin can be discarded, and the other parts can be recycled. Therefore, by disassembling each accessory, for example, by removing the switch from the general winning opening 6, or removing the board from the side lamp 12,
Disposable and non-disposable components (switches,
Substrates, etc.).

[0057]

As described above, according to the present invention, it is possible to reduce the work of removing components that are not suitable for disposal from the game board. For this reason, it is possible to reliably separate the game board into parts suitable for disposal and parts not suitable for disposal, and to promote the recycling while eliminating the problem of disposal processing.
