  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a front view (surface on the user side) of a game board 10 mounted on a ball game machine. The game board 10 is a colorless or colored board material having light permeability such as acrylic resin and having a refractive index higher than that of air, and a plurality of game boards 10 for mounting the game board 10 on a ball game machine. The through-hole 12 is provided. A belt-shaped guide rail (not shown) is provided in an annular shape on the outer peripheral portion of the surface, which is the user side surface of the game board 10. Of the surface of the game board 10, a portion surrounded by the guide rail forms a game area of the ball game machine. In the game area on the surface of the game board 10, obstacle nails, windmills and the like (not shown) are arranged, and the falling path of the game ball is changed.

  The game board 10 has a thickness of about 10 mm, for example, sufficient to hold the obstacle nail disposed on the surface of the game board 10. Two types of straight lines with different inclination angles are arranged at equal intervals on the back surface opposite to the user side of the game board 10 by forming a plurality of long concave portions (concave grooves) 14 by cutting. In this way, a lattice-like decorative pattern intersecting is formed. The depth of the concave portion 14 is formed at a position and depth such that the strength of the game board 10 is maintained in consideration of the position of the obstacle nail, windmill, and the like. Further, uncut shavings (projections) 16 are formed on the back surface of the game board 10 between the recesses 14. 2 is a cross-sectional view of the concave portion 14 taken along the line II-II in FIG. 1 and showing the case where the concave portion 14 has a triangular cross-sectional shape.

  Since the game board 10 is light transmissive, the recess 14 and the projection 16 are provided on the user side of the ball game machine through a glass door (not shown) provided on the user side of the ball game machine and the game board 10. Can be visually recognized. When the concave portion 14 is observed from the user side, the concave portion 14 is represented as a thick three-dimensional line, and a design having a three-dimensional feeling can be applied to the bullet ball game machine at a low cost. Further, since it is not necessary to provide a decorative member behind the game board or a rear decoration layer on the back side of the game board 10, the manufacturing cost of decoration of the ball game machine is low. In addition, because the concave portion 14 reflects and refracts light around and outside the ball game machine, a design with a high visual effect such as a three-dimensional decorative pattern on the game board 10 is given. Is possible.

  Further, for example, when light is applied from the back side of the game board 10 by a light source element such as a light emitting diode or a light bulb (not shown), light is reflected, refracted, diffused, etc. in the recess 14, and the game board The visual effect can be enhanced, for example, by raising the three-dimensional decorative pattern applied to 10. Further, for example, when light is incident from a plurality of light source elements LS that output white light or colored light that is arranged near the outer peripheral end face or the inner peripheral end face of the game board 10 shown in FIG. Light incident from the end face of the plate 10 is guided and reflected by the recess 14. In this way, it is possible to enhance the visual effect such as further raising the three-dimensional decorative pattern applied to the game board 10.

  Further, since the recess 14 has a polygonal cross section, particularly a triangle, reflection and diffusion of ambient light, transmitted light from the back surface, light guided from the end surface, and the like are caused to enter the game board 10 by the recess 14. Since it occurs on the surface of the convex portion formed so as to protrude toward the user side, the visual effect of the decoration is further enhanced.

  Further, at least one recess 14 intersects each other. For this reason, the concave portion 14 is represented as a thick three-dimensional line, and the three-dimensional lines intersect with each other. Therefore, a design with a more three-dimensional effect is applied to the game board 10 of the ball game machine at a low cost. Is possible.

The shape of the cross section of the recessed part 74 shown in FIG. 5 is a rectangle (rectangle).

  FIG. 6 is a cross-sectional view of the concave portion in FIG. 1 taken along the line VI-VI showing the concave portion 74 in FIG. 5 where two linear concave portions 74 having different depths intersect each other. In this way, if the depths of the plurality of longitudinal-shaped concave portions 74 are different from each other at the intersections, the concave portions 74 are represented as thick three-dimensional lines, and the three-dimensional lines are However, since it intersects with a sense of perspective, it becomes possible to apply a more three-dimensional design to a bullet ball game machine at a low cost.

  FIG. 7 is a cross-sectional view showing another example of the long concave portion 84, and is a view corresponding to FIG. 2, showing a state where the bottom portion of the concave portion 84 is colored. The shape of the cross section of the concave portion 84 is a pentagon, and coloring ink 86 is applied to the bottom portion of the concave portion 84. As described above, if at least a part of the surface of the recess 84 is colored, the shadow and color of the design are emphasized by the part colored by the ink 86 when observed from the user side, so that more three-dimensional. A vivid design with a feeling can be applied to the game board 10 at a low cost.

  FIG. 8 is a cross-sectional view showing another example of the long concave portion 94, and is a view corresponding to FIG. 2 showing a state in which the light guide tube 96 is disposed in the concave portion 94. The shape of the cross section of the recess 94 is a so-called U-shape in which two parallel straight lines are connected by a semicircle. A light guide tube 96 is disposed at the bottom of the recess 94. The light guide tube 96 has, for example, a core containing a light diffusing material, and light that is irradiated from a light emitting diode (not shown) and propagates from the end of the light guide tube 96 is scattered. All or part of the direction emits light. As described above, when the light guide tube 96 is disposed in the concave portion 94, the light guide tube 96 emits light in the concave portion 94 by turning on or blinking the light emitting diode that irradiates light to the end portion of the light guide tube 96. Since the shade and color of the design are further emphasized, it is possible to apply a vivid design with a more three-dimensional effect to the bullet ball game machine when observed from the user side.

  FIG. 9 is a diagram showing another decorative pattern of the above-described embodiment. In the game board 110, a plurality of linear concave portions (concave grooves) 114 are formed by cutting. In addition, between the recesses 114, uncut shavings 116 are formed on the back surface of the game board 110.
