Abstract

PROBLEM TO BE SOLVED: To provide a game machine component with which static electricity generated on the front side does not flow to the back side or the like although a metal thin film is formed on a surface. SOLUTION: A groove 20 for plating prevention is formed at a position surrounding the outside of a partition wall 9 on the back side of an attachment part 3. Three grooves 20 for plating prevention are parallelly formed, and a projecting line 24 formed between the adjacent grooves 20 and 20 sharpened so that its cross section can form a triangle and its apex forms an acute angle. Plating for decotation is performed on the surface of a main body part 1 but since the groove 20 is sharply cut in, no metal is deposited at the deepest part of the groove 20. Further, since the projecting line 24 is sharpened, any metal is hardly deposited on the apex of the projecting line 24 as well. Therefore, plating on the attachment part 3 and the partition wall 9 is discontinuous by the grooves 20 and the projecting lines 24, and the surfaces of the attachment part 3 and the partition wall are not electrically connected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine component such as various prize machines and various decoration parts mounted on the game machine, and more particularly, to a game mechanism having a metal coating such as a plating plating formed on a surface thereof. For component parts.

[0002]

2. Description of the Related Art Conventionally, pachinko machines are provided with a large number of components for various game machines, such as various prize devices that directly affect the game contents and various decoration parts that do not affect the game contents themselves. ing. Many of these game machine components are composed of various electric components such as sensors for detecting game balls, lamps and LEDs for decoration, solenoids serving as driving sources for movable parts, various ICs, and other wiring. But,
It has a built-in or adjacent structure.

[0003] Some of such game machine components include:
2. Description of the Related Art Conventionally, there has been one using a plated component. Such a plated component has the effect of increasing the decorativeness due to the metallic luster, and also has the effect of improving the surface hardness of the resin component and suppressing the wear of the resin component due to contact with game balls.

[0004]

However, game machine components employing plated components have the following problems. That is, when the gaming machine component is placed on the game board and is in direct contact with the game ball, the front side of the game machine component tends to generate static electricity due to friction with the game ball and the like. In such gaming machine components, if plated parts are used carelessly,
Since static electricity generated on the front side of the gaming machine component flows to the back side of the gaming machine component via the plating film,
Noise currents may flow through electrical components mounted on or adjacent to the back of the gaming machine component, etc., resulting in malfunction of the electrical component itself or the control device controlling the electrical component. There was fear.

In order to solve such a problem, conventionally, in consideration of the influence on the electric parts as described above, a portion to be plated is selected, and the game components are divided into several parts along the selected portion. Therefore, measures were taken such as making only necessary parts plating parts. However, there is a drawback that the degree of freedom in design is reduced because parts must be divided into shapes that do not lack the strength of each part and that there is no unreasonable connection between parts. As the number of parts increases, the number of required dies increases, which also causes an increase in manufacturing cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to allow static electricity generated on the front side to flow to the rear side and the like despite the metal film being formed on the surface. It is an object of the present invention to provide a gaming machine component part that does not have any problem.

[0007]

Means for Solving the Problems and Effects of the Invention A game machine component according to the present invention, which has been made to achieve the above-mentioned object, is characterized in that the surface of a base material made of an insulating material is made of metal A gaming machine component formed by forming a coating,
The surface of the base material is divided into a first region including a portion exposed to the front side of the gaming machine when mounted on the gaming machine, and a second region that is a portion other than the first region, and A portion where a metal film cannot be formed is provided at a boundary between the two regions.

In the present invention, the game machine components include various winning devices, display devices, decorative parts, and the like mounted on the game machine. In addition, those that are mounted on the game board surface at positions where the game balls fall, those that are mounted on the outer edge of the game board where the game balls do not fall, and those that are arranged on the outer frame of the game machine are also included.

The insulating material is not particularly limited as long as it can be molded, but in the case of manufacturing such game machine components, various synthetic resins are generally used. The metal film may be any metal film formed according to a known thin film forming method, and there is no particular limitation on the specific thin film forming method, type of metal, and the like. As a method of forming a thin film on a resin material, for example, a method in which a base material is immersed in a plating solution to deposit a metal film is generally used. In addition, a vacuum deposition method, a sputtering method, an ion plating method, and the like are also available. In addition, various thin film forming methods can be adopted.

[0010] According to this gaming machine component, since the portion where the metal film cannot be formed is provided at the boundary between the first region and the second region, the thin film forming process is performed so that the metal film is formed over the entire surface. Is performed, a continuous metal film is not formed from the first region to the second region. Therefore, even when static electricity is generated in a portion exposed on the front side of the gaming machine when the gaming machine component is mounted on the gaming machine, the static electricity does not flow out of the first area.

Therefore, there is an effect that various electric components can be mounted or arranged adjacent to the second region of the game machine component without any problem. Also,
Since it is not necessary to divide parts corresponding to the first area and the second area into separate parts, the shape may be difficult to divide, and the number of parts may increase due to the parts divide. No

By the way, the portion where the metal film cannot be formed as described above can be realized by using various methods. For example, if a material which does not easily adhere to a metal component is provided by using a material lacking affinity for the metal component, a metal coating cannot be formed on that portion. However, in such a method, since a different material is used for a portion where a metal film can be formed and a portion where a metal film cannot be formed, the cost tends to be high.

[0013] On the other hand, as in the gaming machine component according to the second aspect, the metal coating is formed in a shape in which the metal component required for forming the metal coating cannot be reached as a part where the metal coating cannot be formed. If the portion is provided, the amount of metal component required for forming the metal film does not reach the boundary between the first region and the second region, so that the thin film forming process is performed so that the metal film is formed over the entire surface. Even if you do, from the first area to the second
No continuous metal coating is formed over the area. In addition, by adjusting the shape of the base material, a portion where a metal film cannot be formed is provided, so that the manufacturing cost can be reduced as compared with the method using another material as described above.

Here, since the behavior of the metal component differs depending on the thin film forming method to be used, the shape in which the amount of the metal component required for forming the metal film cannot be reached may slightly change. The shape may be such that the metal is fixed at the contact position, and the metal component does not reach the position deeper than the contact position, in a shape that is easy to come in contact with something before reaching the predetermined position. . More specifically, for example, as in a gaming machine component according to the third aspect, the metal coating cannot be formed as a portion where the metal component required for forming the metal coating cannot reach the deepest part. If a molded groove is provided, even if the metal component enters the groove, the metal component easily contacts and is fixed to the wall surface inside the groove before reaching the deepest part. Does not extend, and as a result, the metal coating in the first region and the second region becomes discontinuous at the location where the groove is formed.

Particularly, as in the gaming machine component according to the fourth aspect, the plurality of grooves are formed in parallel, and a ridge portion of a ridge formed between adjacent grooves is provided. If the cross-section has an apex that forms an acute angle, a large amount of metal component may enter a certain groove, and even if the metal film may be connected at the deepest part of the groove, Since the metal film becomes discontinuous due to the groove, the possibility that the metal film in the first region and the second region is continuous is extremely low. In addition, since the ridge portion of the ridge formed between the adjacent grooves has a shape in which an apex that forms an acute angle appears in the cross section, the metal component hardly precipitates at this ridge portion. The possibility that the metal coating in the region and the second region is continuous is further reduced. Therefore, the effect of preventing static electricity in the first region from flowing to the second region is extremely enhanced.

[0016]

Next, an embodiment of the present invention will be described with reference to an example. As shown in FIG. 1 (a), a gaming machine component shown in the embodiment is a front side portion of a prize device (a so-called attacker) forming a large prize hole among prize devices mounted on a pachinko machine. Is a main body part 1 that constitutes the above.

The main body 1 has a plate-shaped mounting portion 3 which is mounted to be exposed on the front side of the game board. A screw hole 5 for fixing is provided. At the approximate center of the mounting portion 3, a rectangular opening 7 serving as a special winning opening is formed. As shown in FIG. 1B, the partition 9 projects rearward so as to surround the opening 7, It defines the interior space of the mouth. As shown in FIG. 2A, the partition wall 9 is provided with a screw receiving hole 11 so that a rear part (not shown) attached to the rear side of the main body part 1 can be screwed. The partition 9 is also provided with a bearing 13 and the like for supporting a door component (not shown) which is attached to the opening 7 so as to be openable and closable.

Further, as a feature of the main body part 1, a groove 20 for preventing plating is formed at a position surrounding the outside of the partition wall 9 on the back side of the mounting portion 3. The plating preventing groove 20 is formed on a projecting portion 22 provided on the back side of the mounting portion 3 to secure the depth of the groove 20, as shown in an enlarged view in FIG. The three grooves 20 are formed in parallel over the entire circumference of the projecting portion 22. The ridge 24 formed between the adjacent grooves 20 has a triangular cross section, and has a sharp shape with its apex forming an acute angle.

The surface of the main body component 1 configured as described above is plated with a decoration. Specifically, the metal film is deposited on the surface of the main body part 1 by immersing the main body part 1 in a plating solution. However, since the groove 20 has a sharply cut shape, the deepest part of the groove 20 is formed. No metal is deposited in the part. Further, since the ridges 24 have a sharply pointed shape, metal is unlikely to be deposited on the vertices of the ridges 24.

Therefore, although the mounting portion 3 and the partition 9 are both plated, they are discontinuous due to the groove 20 and the ridge 24, and the surface of the mounting portion 3 and the surface of the partition 9 are
It is in a state of not being electrically connected. Therefore, even if static electricity due to contact with the game ball is generated on the front side of the mounting portion 3, the static electricity does not flow to the partition wall 9, and various electric components are mounted on the partition wall 9 or adjacent thereto. Even if it is arranged, the electric component and the control device to which the electric component is connected do not malfunction.

Although the embodiments of the present invention have been described above, various specific embodiments other than those described above are conceivable for the embodiments of the present invention. For example, in the above-described embodiment, the components for configuring the winning device having the special winning opening have been exemplified. However, various gaming devices such as other winning devices, decorative frames for variable symbol display devices, and other illumination devices, etc. The configuration of the present invention can be adopted in machine components.

Although not described in detail in the above embodiment, the metal film may be formed by any thin film forming method, and a known thin film forming method capable of forming a metal film on a resin material. The law can be adopted arbitrarily.
