Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine for preventing damage caused by static electricity and external electromagnetic waves.

[0002]

2. Description of the Related Art Conventionally, pachinko gaming machines often use easily charged parts and members made of an insulator such as a synthetic resin. Static electricity is generated and accumulated, and when the static electricity is accumulated up to a certain upper limit, a discharge phenomenon occurs. Further, the discharged static electricity collects on metals such as nails and screws, and the collected static electricity often causes malfunction and damage of electronic components. In addition, due to the widespread use of mobile phones and the like, malfunctions and damages are often caused by external electromagnetic waves. As a solution to the above,
Install lead wires and metal plates at places where static electricity is generated.
Discharge was caused by the grounding mechanism, and countermeasures were taken on software. In addition to the above countermeasures, countermeasures are taken by a method of sandwiching a metal foil between plywood as shown in JP-A-6-244 or a method of attaching a conductive seal to a substrate as shown in JP-A-7-24110. is the current situation.

[0003]

SUMMARY OF THE INVENTION As described above, it is a general method to prevent malfunction and breakage of electronic parts due to repeated accumulation and discharge of static electricity. In the method using the grounding mechanism, it is necessary to attach a lead wire and a metal plate to a plurality of static electricity generating parts. As a result, the structure of the pachinko game machine becomes complicated, and it takes a lot of time in the manufacturing process. In addition, component management is complicated, leading to increased costs. Further, it is difficult to install a grounding mechanism using a lead wire, a metal plate, or the like in all the static electricity generating units. Another method is to prevent the collection of high-voltage static electricity by mixing a conductive material such as carbon into parts such as synthetic resin and repeating the accumulation and discharge of static electricity. The mixed components are liable to be damaged due to a decrease in strength, and this measure is temporary.

[0004] In addition to the above, the method of sandwiching a metal foil between plywood as disclosed in Japanese Patent Application Laid-Open No. Hei 6-244 requires time and effort in the process of manufacturing the plywood and hinders the recycling of the plywood to other products. . In addition, the distortion that produces the slump property of the original plywood characteristics is subtly changed to eliminate the elements necessary for the original pachinko gaming machine. In addition, in a method of attaching a conductive sheet to a substrate as in Japanese Patent Application Laid-Open No. 7-24110, the conductive contact between the nail, each winning port, each windmill, and the conductive sheet is performed through one conductive sheet. The conductive contact was incomplete. The present invention has been made to solve these disadvantages.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and to prevent malfunction and damage of electronic parts due to static electricity and external electromagnetic waves. A pachinko gaming machine characterized by using a plywood plate formed by pressing a game board material formed by compressing a game board with a compressed material containing a conductive substance with an adhesive containing a magnetic material.

A game ball is generated by violently colliding and rubbing with a game nail, each winning opening, each windmill, and a decorative film, and the static electricity accumulated in various places, an electromagnetic wave generated by the discharge phenomenon of the static electricity, a mobile phone, and the like. Electromagnetic waves generated from the outside are absorbed through a veneer plate formed by pressing a game board material formed of a compressed material containing a conductive material and pressed with an adhesive containing a magnetic material. As a result of the above, the potential difference between the entire game board and each component is eliminated, thereby preventing accumulation of static electricity, discharge phenomenon and external electromagnetic waves, and preventing malfunction and damage of electronic components.

The game board of the pachinko game machine according to the present invention can be manufactured almost in the same manner as a normal plywood manufacturing process, and even if nails and screws of a predetermined length are used, the electrical conductivity of the plywood board can be improved. Since it reaches the compression part containing the substance, it conducts and the potential difference disappears. Also, since no material other than wood is used in the construction of the plywood, the expansion and contraction tolerance of the material due to changes in temperature, humidity, etc. remains unchanged from the past, so that the adhesion of the plywood due to expansion and contraction does not come off or is damaged, and the plywood is not damaged Without losing the distortion that produces the slump property of
The features of the original pachinko gaming machine can be fully exhibited, and the player can concentrate on the game.

FIG. 4 is a sectional view of a main part of the game board 16. A decorative film 36 is adhered to the veneer board 35 constituting the game board 16, and a game nail 38, each winning opening and each windmill 49 etc. are mounted thereon with nails and screws, and the nails and screws are passed through. The veneer plate 35 is electrically connected to each other via a compressed portion containing a conductive material, and is constantly kept at the same potential. Many boards installed on the back side of the game board 16 and easily-charged parts made of an insulator in contact with the boards are also attached with nails and screws, and the conductive material of the plywood 35 passes through the nails and screws. Are electrically connected to each other via the compressing section containing the conductive material, and are constantly kept at the same potential.

A portion provided with a grounding mechanism using a lead wire and a metal plate, such as a ball tank 24 above the mechanism plate 23 and a curved gutter 26 substantially at the center right of the mechanism plate 23, is also used.
It is attached with nails, screws, etc., and can conduct more reliably.

If a grounding terminal is provided in the compressed portion of the plywood 35 containing the conductive material, and the grounding terminal and the grounding terminal of the game machine installation island are connected by an electric wire, better conduction is possible.

As described above, the game board 16 is a plywood board 3
The veneer plate 35 is made by compressing beech wood and lauan wood containing conductive material to about 1.5 mm, and 13 of them are arranged so that the grain directions are alternately orthogonal to each other. Affixed with an adhesive containing a magnetic material (a ferrite material is used in this embodiment), and the thickness is about 18.5 mm to 1 mm.
It is 9.5 mm. The plywood is cut into predetermined vertical and horizontal dimensions, and has been subjected to a hole processing and a router processing for mounting each accessory, each substrate, and the like.

Since a compression material manufactured by flakes of a conductive material such as a metal such as copper, silver or nickel or carbon or the like is used as the compression material, the adhesive strength and the production cost can be obtained almost unchanged from the conventional one. The compressed material containing the conductive substance is conductive if a part of the nail or the screw is in contact, so that it is not necessary to use the compressed material in all game board materials. In addition, even if the adhesive containing the magnetic material is not used for all game board materials, it absorbs electromagnetic waves from the outside, so the wood near the center of the 13 wood pieces is the same as the conventional compressed material and adhesive. Since an agent can be used, cost can be reduced.

Although it has been described above that an adhesive containing ferrite is used as the adhesive, "ferrite", that is, FeO, Fe
There are compounds represented by three chemical formulas of 304 and Fe203. Of these, it is difficult to make pure FeO,
The magnetic properties of Fe304 are unstable even in a greenhouse and change with time. As a result, F is easy to make, stable and has little change over time.
It is preferred to use e203. Note that Fe203
There are α-type and γ-type, and α-type has the property of absorbing light in the visible region and has strong weather resistance to sunlight. Since γ-type has strong magnetism, α-Fe203 is most suitable.

The above-mentioned three types of ferrites are of the Snel type, and there are other types such as the magnet plumbite type, the perovskite type, and the garnet type, and these can also be used.

An amorphous alloy may be powdered and mixed in place of the ferrite used for the adhesive. Amorphous alloys are non-crystalline metals having a structure in which the arrangement of the constituent metal atoms is irregular, and there are various manufacturing methods such as rapid solidification, sputtering, and mechanical alloying. It is jetted onto a rotating body and rapidly solidified. Amorphous alloys have excellent mechanical properties,
Tensile strength is 3-4 GPa, higher than the highest value of the current high-strength alloy, corrosion resistance, small crystal magnetic anisotropy derived from crystal symmetry, high magnetic permeability and low loss in zero magnetostriction composition The eddy current loss is small due to the large electric resistance and the small plate thickness. It also has excellent magnetic properties at high frequencies.

In the pachinko gaming machine 10 implemented in the conventional configuration, the game ball is fired by rotating the firing lever 21 clockwise, and the game ball is played by the game nail 38, each winning opening, each windmill 49, and Violent collision and friction with the decorative film 36 generates and accumulates static electricity. It is well known that on a game board 16 that uses many easily-charged members, a discharge phenomenon occurs when the static electricity is accumulated to a certain upper limit, and a strong electromagnetic wave is generated. It adversely affects some of the boards provided on the pachinko gaming machine 10 and often causes malfunctions and breaks. Even without discharging on the game board 16, the game ball storing the high-voltage static electricity moved to the back side through each winning opening and the like, and was charged to the game ball near the electronic circuit including the game control microcomputer. In many cases, a high-voltage charge causes a discharge phenomenon that cannot be visually confirmed. Due to the discharge phenomenon, an electronic circuit that is vulnerable to high frequency pulse noise may malfunction from a normal operation to an infinite loop. Furthermore, malfunctions due to external electromagnetic waves have occurred due to the spread of mobile phones and the like in addition to static electricity generated inside.

In addition to the above, the player touches a game ball in which static electricity is accumulated at a high voltage, which does not cause malfunction or breakage, which makes the player very unpleasant or the game board 16 The dust accumulated on the glass 17 installed on the front due to the influence of the static electricity accumulated on the game board 16 impairs the real cleanness of the game board 16. In addition, cleaning of employees to remove the dust is not easy because it is daily.

However, in using the present invention, if the fired game ball violently collides with the game nail 38, each winning opening, each windmill 49, and the decorative film 36 and rubs, the static electricity is generated. As described above, since metal parts such as nails and screws have reached the compressed portion of the plywood 35 containing the conductive material, static electricity flows through the nails and screws and the plywood 35
To prevent electrical charging by maintaining the same potential and maintaining the same potential, preventing malfunction and breakage of electronic components due to accumulation and discharge of static electricity, and preventing damage by dust. Similarly, a malfunction of an electronic circuit due to an electromagnetic wave from the outside such as a mobile phone can be absorbed and prevented by the game board 16, so that the player can concentrate on the game without feeling discomfort.

With the above, it is not necessary to provide a grounding structure for each part, and it is possible to cope with them all together, and it is possible to reduce the number of lead wires and metal plates used for the grounding mechanism.
Costs can be reduced by reducing parts costs and manufacturing time in the manufacturing process.

In addition, external electromagnetic waves are cut off not only by the portable telephone but also by the notebook computer, the wireless device in the 27 mHZ band, the transceiver, and the like by the game board 16, so that malfunction and breakage of the electronic circuit can be prevented.

In the above embodiment, the first type of pachinko gaming machine has been described. However, the present invention can be suitably applied to the second and third type of pachinko gaming machines.

[0032]

According to the present invention, malfunctions and breakage of electronic components due to static electricity and external electromagnetic waves at a plurality of places with a simple structure without making significant changes in the structure and appearance of the pachinko gaming machine 10. Can be provided all at once. That is, by using the veneer board 35 formed by pressing the game board material formed by compressing the game board 16 of the present invention with a compressed material containing a conductive substance with an adhesive containing a magnetic material, a game ball is synthesized. The accumulation and discharge of static electricity generated by violently colliding with and rubbing against parts and members made of insulating material such as resin can be transferred to the game board 16 through nails and screws used to attach parts and the like.
Can be electrically connected to each other through the compressed portion containing the conductive material of the veneer plate 35, and can be constantly kept at the same potential, thereby preventing malfunction and breakage of electronic components due to accumulation and discharge of static electricity. . Further, an electromagnetic wave from the outside such as a mobile phone is applied to the veneer board 35 serving as the game board 16.
Therefore, malfunction and damage of the electronic component due to electromagnetic waves can be prevented. In addition, since materials other than wood are not used for the configuration of the plywood 35, the expansion and contraction tolerance of the material due to changes in temperature, humidity, and the like is the same as in the past, and the adhesion of the plywood 35 due to the expansion and contraction may cause peeling or breakage. In addition, the bonding strength is almost the same as that of the conventional plywood, and the cost related to the configuration of the plywood is not so different. The cost related to the construction of the plywood is that the nails and screws used to attach the parts can use the conventional ones, and in order to make it conductive,
Since the nails and screws only need to be in contact with at least two of the game board materials, the game board material near the center of the 13 game board materials can use the same compression material and adhesive as before, so It is no different from the conventional production cost. In addition, plywood 3
The original characteristics of the pachinko gaming machine 10 can be fully exhibited without losing the distortion that produces the slump property of the characteristic 5 and the player can concentrate on the game. In addition, at the time of disposal of the pachinko machine, the veneer board 35 becomes only the decorative film 36 and the wood if the objects attached with nails and screws, such as the game nails 38, each accessory and each windmill, are removed. And can be easily recycled for other products.
