Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plated part for a gaming machine, which is formed by plating the surface of a plastic molded product.

[0002]

2. Description of the Related Art Conventionally, among the parts to be assembled on the front side of a gaming machine such as a pachinko machine, there are those that have a metallic luster at a low cost by plating the surface of a plastic molded product. There are many. When patterns, characters, symbols, etc. are formed on the surface of such a plated component, it is formed by printing a paint on the plated surface.

[0003]

In the above prior art, when a pattern, a character, a symbol or the like is formed on the surface of the plated component, it is necessary to perform the printing process after the plating process, which increases the number of processes. There was a drawback that the production cost was high.

Further, in the conventional plated parts, the entire surface is plated and does not transmit light at all, so even if a lamp or the like is used to provide an illumination effect from the back of the parts, This is not possible with the processing parts alone. For this reason, in the conventional plating-processed component, the portion (translucent lens) having the illumination effect is formed by another transparent or translucent component, and the component is used in combination with the plating-processed component. Therefore, the number of parts is increased, the assemblability is deteriorated, and the cost is increased.

The present invention has been made in consideration of such circumstances, and a first object thereof is to perform printing after the plating treatment step in the case of forming a design, a character, a symbol, etc. on the surface of the plated treatment component. It is an object of the present invention to eliminate the need for a process, and to make it possible to inexpensively form patterns, letters, symbols, etc. on the surface of a plated component, and the second purpose is to combine the plated component with a separate lens component. Even so, the illumination effect can be provided, and the number of parts can be reduced, the assemblability can be improved, and the cost can be reduced.

[0006]

In order to achieve the above object, the plated parts for gaming machine according to claim 1 of the present invention form a part of the surface of a plastic molded product which is not plated. As a result, the display portion for the design, characters, symbols, etc. is represented by the portion not subjected to the plating treatment. Thereby, a pattern, a character, a symbol, etc. can be simultaneously formed on the surface of the plated component in the plating process.

According to the second aspect of the present invention, the plastic molding is formed of transparent or translucent plastic, and the plating treatment is performed by forming a part of the surface of the plastic molding which is not subjected to the plating treatment. The part that is not applied is used as the translucent lens part. Thereby, the plated component and the translucent lens portion can be integrated, and the translucent lens portion can be simultaneously formed in the plating process.

Embodiments of the present invention will be described below with reference to the drawings. The plated component 11 shown in FIG.
It is a start chucker attached to the game board surface,
It is made of a plastic that is easy to plate (for example, ABS resin, polypropylene, etc.), and its surface is plated. Further, on the surface of the start chucker 11, there is formed a display portion 12 including characters / symbols such as “START” and a design such as “☆”. This display unit 12
The forming method is to form a part on the surface of the start chucker 11 that is not partially plated according to the shape of the above-mentioned letters, symbols, and patterns, so that the pattern, letters, and symbols are formed on the part that is not plated. It is a representation of the display unit 12 such as.

Further, the plated component 13 shown in FIG.
An operation handle for a pachinko ball launching device provided on the lower right side of the pachinko machine, which is also made of a plastic that is easy to plate (for example, ABS resin, polypropylene, etc.), and the surface of which is plated. On the surface of the operation handle 13, a display portion 14 including characters and symbols such as "MRD" is formed. This display unit 14
Also, as in the case described above, by forming a part of the surface of the operation handle 13 which is not plated,
The display unit 14 is represented by a portion not subjected to the plating treatment.

3 and 4 is a front cover of a variable winning device attached to the surface of the game board, which is also formed of a plastic that is easy to plate (for example, ABS resin, polypropylene, etc.), A plating film 17 is formed on the surface of the plastic molded product 16 (see FIG. 4). The front cover 15 is formed with a horizontally long winning opening 18, and a transparent lens portion 19 having, for example, a "*" shape is formed on both sides of the winning opening 18. The method of forming the transparent lens portion 19 is such that the plastic molded product 16 is formed of transparent or semitransparent plastic, and the surface of the plastic molded product 16 is partially plated according to the shape of the transparent lens part 19. By forming the non-plated portion, the non-plated portion is used as the translucent lens portion 19.

As shown in FIG. 4, a boss portion 20 integrally formed on the back surface of the front cover 15 is fixed to a substrate 21 with a screw 22, and light emitted from a lamp or the like arranged on the back side of the translucent lens portion 19 is emitted. The element 23 is attached to the substrate 21. Then, when the light emitting element 23 is caused to emit light, the light passes through the light transmitting lens portion 19, so that an illumination effect can be provided.

Next, a plating method for the above-mentioned plated parts will be described with reference to FIG. First, a masking coating (plating resist coating) conforming to the shape is formed by printing or the like on the portion where the display portions 12, 14 such as designs, characters, symbols, etc. and the translucent lens portion 19 are formed. A portion of the surface of the molded product where the masking film is not formed is subjected to chemical plating treatment as follows. First, the surface of a plastic molded article is chemically treated to impart hydrophilicity, washed with neutralized water, chemically etched, and washed with water. After this, the catalyzing to deposit the colloidal substance on the surface of the plastic molded product is performed, washed with water, and then subjected to the acceleration (activation treatment), and this is put in the nickel plating solution, and nickel is applied to the surface of the plastic molded product. Apply plating. At this time, the plating film is not formed on the portion where the masking film is formed on the surface of the plastic molded product, so that the display portions 12 and 14 of the design, characters, symbols and the like and the translucent lens portion 1 are formed.
9 is simultaneously formed in the plating process.

Since the chemical plating film formed by the above procedure has low strength, electroplating is performed on it to form a strong plating film. This electroplating is performed according to the following procedure. A chemically molded plastic molded product is placed in, for example, a copper sulfate plating solution to be subjected to electroplating for a base, and then washed with water, and this is placed in a nickel plating solution and electroplated to perform nickel plating. Further, this is washed with water, and finish plating is performed in a plating solution containing chromium, gold, an alloy and the like. Through the above processing, the electroplating process is completed, and the electroplating process is washed with water and dried, and finish printing is performed if necessary (finish printing is not necessarily required). Even during this electroplating process, the plating film is not formed on the portion where the masking film is formed on the surface of the plastic molded product.

As described above, in the plated components 11 and 13 shown in FIGS. 1 and 2, the plating treatment is performed by forming a part of the surface of the plastic molded product which is not subjected to the plating treatment. Since the display portions 12 and 14 such as patterns and characters are expressed by the non-existing portions, the display portions 12 and 14 can be formed at the same time when the surface of the plastic molded product is plated in the plating process. The printing process after the plating process is unnecessary, and the demand for productivity improvement and cost reduction can be satisfied.

In the plating-processed component 15 shown in FIGS. 3 and 4, a plastic molded product 16 made of transparent or translucent plastic has a surface on which a part not subjected to plating is formed. Transparent lens part 1
Since it is used as 9, it is possible to integrate the plated component 15 and the translucent lens portion 19, and at the same time, the surface of the plastic molded product 16 is plated in the plating process, and at the same time, the plated component 15 is transparent. The lens portion 19 can be formed. As a result, the plated component 1
It is possible to provide an illumination effect without combining a separate lens component with 5, and it is possible to reduce the number of components, improve the assemblability, and reduce the cost.

It is needless to say that the present invention is not limited to the parts of the above-mentioned embodiment, and the present invention can be applied to various plated parts mounted on the front side of a gaming machine such as a pachinko machine.
