Description

The present invention relates to a game board of a pachinko gaming machine, and more particularly to a game board of a pachinko gaming machine using a metal substrate.

There are game machines of pachinko machines that use veneer for the board (for example, see Patent Document 1) and those that use resin (for example, see Patent Document 2).

The veneer substrate is made of wood, and it is predicted that it will become difficult to secure the raw material continuously from the viewpoint of emphasizing protection of the natural environment.
On the other hand, a resin substrate can be expected in terms of securing raw materials rather than a veneer substrate in that industrial recycling technology for waste materials has been established. On the other hand, however, the strength characteristics for supporting the obstacle nail implanted on the surface of the substrate are inferior to those made of veneer.

There are two obstacle nails arranged side by side at the same interval as the inner diameter of the openings above the start winning opening or passage opening. These obstacle nails are used by repeatedly fine-tuning the inclination every time depending on the game shop's operating style that changes from day to day, but a resin substrate is not suitable for such usage. .
In addition, the resin substrate has a feature that the surface is easily charged with static electricity during handling. When switching the manufacturing process of the veneer substrate to the manufacturing process of the resin substrate, the dust caused by such charging is reduced. Additional investment is required to provide additional equipment and processes to prevent adsorption.

On the other hand, a metal substrate has been proposed by focusing on the point that the metal waste material can be industrially reused (see, for example, Patent Document 3).

The game board according to Patent Document 3 is arranged between a double-sided board so as to keep a predetermined distance between a gaming side faceplate on which obstacle nails are arranged, a backside side board arranged opposite to the gaming side faceplate, and the doublesided board. These are all made of metal.
In this game board, the obstacle nail support structure is such that the obstacle nail is passed through a through-hole penetrating from the game side plate to the back side plate, and the tip of the obstacle nail is welded directly to the back side plate, or It is formed by driving obstacle nails into a sleeve unit (made of metal) welded to the back side.

If the material of the board is unified with metal in this way, the obstacle nail is originally made of metal, so the used board is put into the recycling process with many obstacle nails arranged on the surface. can do. That is, it is possible to omit the step of removing the obstacle nail from the substrate as a pre-process of recycling, and it is possible to save the total cost and energy consumption of the recycling.

In the metal substrate described above, if the position of the obstacle nail overlaps the hollow structure, both the supporting strength of the obstacle nail and the structural strength of the substrate itself are adversely affected. Therefore, when designing the arrangement of the obstruction nail, there is a constraint that a hollow structure must be avoided.

Further, the direct welding of the obstacle nail or the welding of the sleeve unit for supporting the obstacle nail in the metal substrate described above is performed at the peripheral portion of the through hole having a diameter of about 2 mm provided in the metal plate. Therefore, there is a concern that the coefficient of restitution of the obstacle nail supported on the substrate may vary due to a slight difference in welding processing accuracy.
Further, generally, there is a defect that rust is likely to be generated due to a change in composition around the welded portion, and the influence of the rust on the coefficient of restitution cannot be ignored.

Since the fine adjustment of the inclination in the amusement store is performed within a range of slight differences that cannot be discerned visually, it is difficult to adjust according to the intention if the coefficient of restitution differs between the multiple obstacle nails. Problems arise.

Furthermore, in the process of welding each of the obstacle nails to be implanted on the board, the production efficiency is greatly reduced compared to the nailing process using the nailing apparatus that has been used for veneer or resin boards. Therefore, there is a problem that the total cost increases.

By the way, an industrial material called metal foam is being researched in research institutions.
This is an application of the cell structure found in foamed polystyrene to metals, and a mixture of a metal powder such as aluminum and a foaming agent is heated to the liquid phase temperature of the metal powder to produce a large number of minute particles inside. The pores are confined and produced as a low-density metal material.
This metal foam is excellent in heat insulation, soundproofing, and shock absorption characteristics, and is expected as an industrial material that can be significantly reduced in weight while ensuring rigidity by replacing with a conventional structural member.

The present invention has been made in view of the above circumstances, and uses a metal substrate that can be recycled to solve various problems in the support structure of the obstacle nail and from the manufacture of the gaming machine to the recycling. The purpose is to provide a game board of pachinko machines that can reduce the total cost up to.

In order to achieve the above object, a gaming board of a first pachinko gaming machine according to the present invention is constructed such that a gaming ball can be brought into contact with a board made of metal foam and a surface side of the board. It comprises an obstacle nail.

In addition, the gaming board of the second pachinko gaming machine according to the present invention includes a highly insulating sheet member, and on the surface side of the substrate, a region where the game ball can abut is concealed by the sheet member. It is characterized by.

The gaming board of the third pachinko gaming machine according to the present invention is a gaming machine component that is provided with a through hole in the substrate and is attached to the inner wall of the through hole in a state of being arranged inside the through hole. It is characterized by providing.

A gaming board of a fourth pachinko gaming machine according to the present invention includes an electrode provided in contact with one surface of the substrate, and the electrode is electrically connected to an external ground electrode maintained at a ground potential. The electric charge of the game ball in contact with the obstacle nail is guided to the ground electrode by using a metal substrate as an electric circuit.

According to the game board of the first pachinko machine, the use of a metal foam substrate makes it possible to recycle resources while planting obstacle nails by the conventional nailing device. This is advantageous for saving the total cost.

Further, since the metal foam substrate is produced by heating a mixture of metal powder and foaming agent to the liquid phase temperature of the metal powder, the strength characteristics are generally uniform.
Therefore, according to the gaming board of the first gaming machine, it is possible to solve the problem that adjustment according to the intention becomes difficult due to variations in the coefficient of restitution of the obstacle nail.

According to the gaming board of the second pachinko gaming machine, since the metal foam substrate is made of metal, the metal gaming ball that rolls and falls on the surface thereof is worn by friction. Therefore, by interposing a sheet member between the game ball and the substrate, it is possible to reduce the friction between them and to reduce wear of the game ball. Moreover, the effect which relieves the collision sound of metals can be anticipated by making such a sheet | seat member into resin, for example.

By the way, a veneer substrate made by laminating and bonding thin wooden boards exhibits sufficient strength characteristics for mounting in a thickness direction perforation, but has extremely strong strength characteristics for mounting in a direction along a layer. To drop.

On the other hand, since the metal foam substrate has substantially uniform strength characteristics as described above, no directivity is generated in the strength characteristics regardless of the orientation of the mounting surface.

That is, according to the gaming board of the third pachinko gaming machine that employs a board made of metal foam, for example, the inner wall of the through hole of the board can be drilled to provide a mounting hole, where a gaming machine part such as a center case can be attached. It is.
That is, since the degree of freedom increases in designing the mounting surface of the gaming machine parts, the superiority in design construction is improved.

In addition, the metal foam substrate can also function as a component for removing static electricity from a statically charged game ball. Further, at this time, the electrode attached to the substrate side for conducting the substrate and the ground electrode may be attached anywhere on the substrate.
Therefore, according to the game board of the fourth pachinko machine, the degree of freedom in designing the wiring of the ground wire connected to the electrode provided for static elimination can be increased.
