Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a pachinko machine frame, more specifically, an ABS resin which is molded from a synthetic resin such as resin and is pivotally supported by a door-like opening / closing on an outer frame. A resin hard coat film with high hardness is applied to prevent the formation of minute flaws and stains on the surface of the inner frame molded from resin material, etc., so that even if stains are adhered, it can be easily cleaned. It is a thing.

(Prior Art) Pachinko machine frame, especially the inner frame that pivotally supports the outer frame like a door is made of plywood with a thickness of about 18 mm to 20 mm, and a synthetic resin decorative plate with high hardness is laminated on the front surface. However, attention has focused on synthetic resin moldings, which have a low manufacturing unit price. However, as for the inner frame, the glass frame is screwed freely to open and close, and the handle member for ball striking, ball receiving tray, etc. are attached to the lower part,
Since the employees of the game arcade often have to open and close when necessary, there are many opportunities for players and employees to touch.
However, ABS is low in hardness to mold this with synthetic resin.
Since resin materials such as resin must be used, there are many cases where minute flaws are generated or dirt is attached due to transportation, installation, opening / closing during installation, tentacles, etc. is necessary.

(Problems to be solved by the invention-Purpose of the present invention) The present invention results from the low surface hardness of the inner frame of the pachinko machine frame, which is made of a synthetic resin that can be mass-produced at low cost. It is an object of the invention to solve the problem of eliminating the drawbacks.

(Means for Solving Problems) The present invention meets the above-mentioned object. Specifically, an inner frame to be attached to the outer frame in the shape of a door is molded of synthetic resin, and the inner frame surface is formed. A pachinko machine frame characterized by being coated with a resin hard coat film having a hardness of about 3 to 7 H in terms of pencil hardness. By forming a hard coat film, it is possible to maintain the aesthetics of the pachinko machine frame. It is possible.

A preferred embodiment of the present invention will be described below.

(Example) FIG. 1 illustrates an inner frame 1 of a pachinko machine frame formed of a synthetic resin such as ABS, which is composed of an inner frame body 2 and a front plate 3 and is provided in front of the inner frame body 2. The face plate 3 is attached with an adhesive or the like as shown in FIG. 2 to form one body, and thus the inner frame 1 is formed.

The inner frame 1 is provided with a window hole 4 to which a glass frame (not shown) is attached, and a lower portion is provided with a handle for hitting a ball and a mounting portion 1a for mounting a ball tray.

The inner frame body 2 may be provided with a reinforcing bar 5 which is covered by the front plate 3 and is invisible in the state shown in FIG.

In the present invention, the resin hard coat material is sprayed on the above-mentioned resin inner frame 1 by spooling, or is applied by brushing or the like to form the hard code film 6.

As the hard coat material, an ultraviolet curable resin composition or a heat curable resin composition is used.

This resin composition preferably contains an acryloyl group- and / or methacryloyl group-containing resin, a photopolymerization initiator and / or a thermal polymerization initiator, among which ester methacrylate, epoxy methacrylate, urethane methacrylate. Among them, those containing at least two kinds are preferable. A methacrylate monomer may be added to this resin composition for the purpose of lowering the viscosity or adhering to the resin material of the inner frame 1. The photopolymerization initiator may be one that can be activated by an ultraviolet irradiation lamp, such as a high pressure mercury lamp, a metal highland lamp, or a xenon lamp, and the thermal polymerization initiator can be one that is activated by a hot air heater or a thermal infrared lamp. Good.

As the thermosetting composition, there may be a case where a silicon-based composition composed of a Si—O—Si bond containing an inorganic organosiloxane and an organic material is used.

The resin cord material composed of each composition described above is applied to the surface of the inner frame 1 in FIG. 2, particularly to the front surface a and the peripheral surface b in a thickness of 5 to 50 μm, and then treated by ultraviolet irradiation or heat treatment to harden it. The coat film 6 is fixed.

The hardness of the synthetic resin inner frame 1 is usually about H in terms of pencil hardness. The hardness of the hard coat film 6 of the present invention is preferably about 3 to 7H in terms of pencil hardness, and the hardness of 2H or less easily causes a flaw on the surface of the inner frame 1, and the hardness of 8H or more is too hard and cracks. Even if the hard coat film 6 is applied, stain resistance and durability hardly occur.

(Effects) In the present invention, the inner frame 1 to be attached to the outer frame in a door shape is molded from synthetic resin, and the surface of the inner frame 1 is converted into a pencil hardness of 3 to 7.
The inner frame 1 made of synthetic resin of the pachinko machine frame has a structure in which the resin hard coat film 6 having a hardness of about H is applied, and is often used in an environment where it is often touched or touched and dust is easily attached. Although it is easily scratched, the resin hard coat film 6 is formed on the surface of the film, so that the hardness is remarkably enhanced.
Scratches and stains are less likely to occur. In addition, even if it gets dirty, it can be easily wiped off and its durability can be extended, so that it has the effect of maintaining a beautiful and clean feeling.
