  An embodiment of a game board according to the present invention will be specifically described with reference to the drawings.

  FIG. 1 shows the configuration of a pachinko machine 1 that is an example of a game machine equipped with a game board 2 according to the present invention. A decorative sheet 4 is provided on the surface of a base material 3 composed of a synthetic resin plate, a veneer plate or the like of the game board 2.

  FIG. 2A shows a configuration of the sheet body A before the heat treatment in which the decorative sheet 4 is provided on the base film 5 via the release layer 6. As shown in FIG. 2A, the sheet body A is provided with a release layer 6, a protective layer 7, a decoration layer 8, and an adhesive layer 9 sequentially laminated on the base film 5 by a printing process. The adhesive layer 9 is melted by heat and welded to the base material 3.

  As an example of the base film 5, a PET (Polyethylene terephthalate) film can be applied. As an example of the release layer 6, melamine having excellent release properties can be applied. Note that the release layer 6 is not necessary when the protective layer 7 has good release properties from the base film 5 made of a PET film. As an example of the protective layer 7, an ultraviolet curable acrylic resin can be applied. As an example of the decorative layer 8, ink can be applied.

  Note that FIG. 2B is obtained by omitting the release layer 6 of the sheet body A shown in FIG. 2A, and FIG. 2D is a decorative layer of the sheet body A shown in FIG. The conductive layer 10 is laminated between the adhesive layer 8 and the adhesive layer 9 by a printing process.

  The decorative sheet 4 shown in FIGS. 2A and 2B is heat applied at the time of heating roll molding shown in FIG. 4 and described later, or at the time of in-mold molding shown in FIGS. 5 and 6 and described later. Thus, as shown in FIG. 2 (g), the slip agent particles 11a such as wax, silicone, fluorine, etc. contained in the protective layer 7 are on the base film 5 side (release layer 6 side) of the protective layer 7. As shown in FIG. 2C, a sliding layer 11 is formed.

  As the slipping agent for forming the sliding layer 11, ionomer (IO), silicone, and fluorine-based material made of a synthetic resin that uses agglomeration force of paraffin, polyethylene, and metal ions to aggregate the polymer can be applied. is there.

  The slipping layer 11 may be coated or coated with a slipping agent such as wax, silicone, or fluorine directly on the surface of the protective layer 7 using a spray or a waste cloth. Alternatively, it may be formed by printing.

  As shown in FIG. 1 (b), when the decorative sheet 4 is attached to the surface of the base material 3 of the game board 2, the release layer 6 is provided in the sheet body A shown in FIG. 2 (a). Peel from the sliding layer 11 formed on the inner surface side of the protective layer 7. In the sheet A shown in FIG. 2B, the base film 5 is peeled from the sliding layer 11 formed on the surface of the protective layer 7. The decorative sheet 4 from which the base film 5 (and the release layer 6) has been removed is shown in FIG. And it affixes on the surface of the base material 3 of the game board 2 through the contact bonding layer 9 of the decoration sheet 4 shown in FIG.2 (c). As shown in FIG. 1B, a portion where the decorative layer 8 is not present between the adhesive layer 9 and the protective layer 7 becomes a transparent portion 12.

In the present embodiment, as shown in FIGS. 3A and 3B, the decorative sheet 4 of the game board 2 is horizontally arranged, and water drops 13 are formed on the surface of the sliding layer 11 provided on the surface of the decorative sheet 4. slip layer 11 is formed by a lubricant such as contact angle theta of water on the surface of the該滑Ri layer 11 is set to 60 degrees or more at the minimum angle theta _min when added dropwise. As an apparatus for measuring the contact angle θ of water, “Automatic Contact Angle Meter FAMAS DM-501 (trade name)” manufactured by Kyowa Interface Science Co., Ltd. can be used.

  When the decorative sheet 4 is actually incorporated into the game board 2 of the pachinko machine 1 and the pachinko balls are continuously hit 800,000 times, the water contact angle θ of the sliding layer 11 provided on the surface of the decorative sheet 4 is 45 degrees. When the angle is ˜59 degrees (when the water contact angle θ is smaller than 60 degrees), the decorative sheet 4 is scraped and the base material 3 is exposed. Further, slight scratches occurred on the surface of the protective layer 7 when the water contact angle θ of the sliding layer 11 provided on the surface of the decorative sheet 4 was in the range of 60 degrees to 80 degrees. Further, it was confirmed that the surface of the protective layer 7 was intact when the water contact angle θ of the sliding layer 11 provided on the surface of the decorative sheet 4 was in the range of 81 degrees to 100 degrees. Even when the water contact angle θ of the sliding layer 11 provided on the surface of the decorative sheet 4 exceeds 100 degrees, there is no particular problem, and the water contact angle θ of the sliding layer 11 provided on the surface of the decorative sheet 4 described above. The same result as that obtained at 81 degrees to 100 degrees is obtained.

  Here, when the water droplet 13 is dropped on the surface of the solid, the water droplet 13 is rounded by its own surface tension, and the contact angle θ of the water is adopted as an index representing “wetting”. When the contact angle θ of water is small, it is easy to get wet, and when the contact angle θ of water is large, it is difficult to get wet.

  As shown in FIGS. 3 (a) and 3 (b), it is assumed that the cross-sectional contour shape of the water droplet 13 passes through the intersection p between the cross-sectional contour shape of the water droplet 13 and the surface of the sliding layer 11, and that the cross-sectional contour shape of the water droplet 13 is a part of a circle. The angle between the tangent L of the circle and the surface of the sliding layer 11 closer to the water droplet 13 than the intersection point p can be obtained as the contact angle θ.

  As the slip agent capable of forming such a slip layer 11, paraffin, polyethylene, ionomer, silicone, and fluorine-based material are suitable. Such a sliding layer 11 has organic molecules uniformly arranged on the surface and water repellency, so that the contact angle θ of water becomes large.

  Further, the sliding resistance of the sliding layer 11 provided on the surface of the decorative sheet 4 may be set to 20 N or less. As shown in FIG. 3 (c), the sliding resistance is such that the decorative sheet 4 of the game board 2 is horizontally arranged and the surface of the sliding layer 11 provided on the surface of the decorative sheet 4 is made of stainless steel (SUS). When the tension gauge 15 is connected to a sphere 14 having a weight of 4 kg ± 0.04 kg and is pulled in a predetermined direction, it is measured by the tension gauge 15. As the tension gauge 15, “N round (bar) tension gauge standard 50N (trade name)” manufactured by Oba Keiki Seisakusho Co., Ltd. can be used.

  When the decorative sheet 4 is actually incorporated in the game board 2 of the pachinko machine 1 and the pachinko balls are continuously hit 800,000 times, if the sliding resistance of the sliding layer 11 provided on the surface of the decorative sheet 4 is 20 N or less It was confirmed that the surface of the protective layer 7 was almost intact, or a slight scratch was generated on the surface of the protective layer 7. When the sliding resistance of the sliding layer 11 provided on the surface of the decorative sheet 4 is 21 N or more (when it exceeds 20 N), the decorative sheet 4 is scraped, and the base material 3 is exposed.

  The conductive layer 10 shown in FIGS. 2D and 2E is an example in which the conductive layer 10 is provided on the inner side (the base material 3 side) of the decorative layer 8 of the decorative sheet 4. In this case, the conductive layer 10 is opaque. It can be made of a transparent or translucent material.

  As shown in FIG. 2 (f), a transparent or translucent conductive layer 10 may be provided on the outer side of the decorative layer 8 of the decorative sheet 4 (on the surface side of the game board 2).

  As shown in FIG. 4A, the sheet A shown in FIG. 2A is placed on the base material 3 previously injection-molded so that the adhesive layer 9 is on the base material 3 side. The rubber roll 17 heated to a temperature of 200 ° C. to 240 ° C. is moved along the sheet body A while pressing the sheet body A from the left direction to the right direction in FIG. (See (b)).

  When the sheet A (generally heat transfer foil) is heated and pressed by the rubber roll 17, the adhesive layer 9 is bonded to the base material 3 (thermal transfer). At this time, a slipping agent such as wax is included in the protective layer 7, and the protective layer 7 is formed as a layer having both protection of the decorative layer 8 and sliding performance. In this case, the heat transfer temperature can be set by setting the temperature of the rubber roll 17 to 200 ° C. to 240 ° C.

  Then, as shown in FIG. 4C, after the rubber roll 17 is retracted from the sheet body A, the adhesive layer 9, the decorative layer 8, the protective layer 7, and the By cutting at the depth of the sliding layer 11, the decorative sheet 4 is peeled off from the release layer 6 and attached to the surface of the base material 3. A sliding layer 11 is formed on the surface of the decorative sheet 4. 2B and 2D can be similarly heated and pressure-molded by the rubber roll 17 heated by the heater 16. FIG.

  5 and 6 are diagrams for explaining how the decorative sheet 4 and the game board 2 are integrally manufactured by in-mold molding. First, as shown in FIG. 5 (a), the molds 18a and 18b for injection molding are opened, and the sheet body A shown in FIG. 2 (a) is inserted. As shown in FIG. A vacuum is drawn on the mold 18a side, and the base film 5 of the sheet A is brought into close contact with the surface of the mold 18a.

  Next, as shown in FIG. 5 (c), the surface of the male mold 18b is brought into contact with the adhesive layer 9 side of the sheet A (generally in-mold transfer foil) to close the molds 18a and 18b. (In-mold molding). Then, as shown in FIG. 5 (d), a synthetic resin 20 serving as a material of the base material 3 is injected from an injection port 19 provided in the mold 18b, and the base material 3 is applied as shown in FIG. 6 (a). The concave portion to be molded is filled with the synthetic resin 20 and heated to a predetermined temperature.

  At that time, if the base material 3 made of the synthetic resin 20 is molded and melted and fixed to the adhesive layer 9, and the slipping agent such as wax is included in the protective layer 7, the protective layer 7 is made of the decorative layer 8. It is formed as a layer that combines protection and sliding performance. In this case, the temperatures of the molds 18a and 18b are set to 60 ° C to 100 ° C. The temperature of the synthetic resin 20 to be molded is set to 200 ° C to 250 ° C.

  When the molds 18a and 18b are cooled and the base material 3 made of the synthetic resin 20 is cured, the mold 18b is opened and retracted as shown in FIG. 6B, and as shown in FIG. 6C. Further, the decorative sheet 4 is peeled off from the release layer 6 by cutting the adhesive layer 9, the decorative layer 8 and the protective layer 7 along the outer shape of the base material 3 with a cutting device (not shown). 3 is provided. The sheet A shown in FIGS. 2B and 2D can also be molded integrally with the base material 3 by injection molding of the synthetic resin 20 using the molds 18a and 18b. If a slipping agent such as wax is included, the protective layer 7 is formed as a layer having both protection of the decorative layer 8 and sliding performance.

  The protective layer 7 of the present embodiment is formed with a thickness of several μm (for example, about 1 μm to 10 μm). If the protective layer 7 is thick, the decorative sheet 4 is curled, or it is difficult to cut along the outer shape of the base material 3 at the depth of the adhesive layer 9, the decorative layer 8, and the protective layer 7. Becomes easy to come out. The hardness of the protective layer 7 is preferably about B to 4H in pencil hardness.

  According to the play board 2, the sliding layer 11 provided on the surface of the decorative sheet 4 allows a sliding body such as a pachinko ball to slide on the sliding layer 11 having a low frictional resistance. It is difficult for fading to occur. In particular, when it is used as the game board 2 of the pachinko machine 1, the durability performance against the contact of the pachinko balls on the surface of the game board 2 can be obtained when 800,000 or more pachinko balls are launched.

  Further, the conductive layer 10 provided on the decorative sheet 4 can shield the electromagnetic waves of the mobile phone and the static electricity charged on the pachinko balls to prevent malfunction of the pachinko machine 1 serving as a game machine. Also, the conductive layer 10 could be easily provided on the game board 2.

  Further, by providing a transparent or translucent conductive layer 10 outside the decorative layer 8 of the decorative sheet 4, the decoration applied to the decorative layer 8 can be visually recognized through the transparent or translucent conductive layer 10. . The transparent or translucent conductive layer 10 is preferably provided between the protective layer 7 and the decorative layer 8 or between the adhesive layer 9 and the decorative layer 8.
