Next, an embodiment of the present invention will be described with reference to a game board unit that is detachably incorporated into a ball game machine. As shown in the exploded perspective view of FIG. 4, the game board unit 1 shown in FIGS. 1 to 3 includes a table component 2, a game board 3, a light guide plate 4, a concave-convex molded sheet 5, and a diffusion sheet 6. , A light emitting substrate 7, an assembly case 8, and a symbol variation display device 9. The game board 3 is formed with a large penetrating window hole 3a in the center by undergoing appropriate steps such as injection molding, extrusion molding, and cutting of a transparent or translucent synthetic resin capable of transmitting light. The component mounting holes 3b to 3e are formed in a penetrating shape, and the positioning holes 3f are formed in the square portion. Then, a stainless steel ball guide rail 3g is fixed to the front surface of the game plate 3. The table part 2 is composed of a large winning opening 2a, a variable winning opening 2b, a multiple winning opening 2c, a passing chucker 2d, a center frame 2e, etc., and the large winning opening 2a, a variable winning opening 2b, a multiple winning opening 2c, and passing. The chucker 2d is fitted into the component mounting holes 3b to 3e, respectively, and the center frame 2e is fitted into the inner circumference of the window hole 3a. Then, as shown in FIG. 1, a large number of game nails and wind turbines for guiding the game ball are firmly planted in the inner game area of the ball guide rail 3 g of the game plate 3. Further, the light guide plate 4 is a transparent thin plate in which irregularities capable of refracting light like a lens are formed on the back surface of a transparent resin sheet in a streak shape, and the light guide plate 4 is attached to the back surface of the game plate 3. ..

The concavo-convex molded sheet 5 is formed by thermoforming a thermoplastic synthetic resin sheet having a thickness of 1 mm or less on which desired figures such as patterns, characters, and characters are printed in advance. It will be done. That is, the heat is obtained by heating and softening the thermoplastic synthetic resin sheet, and then vacuum forming or vacuum forming the thermoplastic synthetic resin sheet using a molding die such as a plaster mold, a wooden mold, or a mold. Concavities and convexities are formed on the sheet made of a plastic synthetic resin so that figures and the like are displayed three-dimensionally by the irregularities. In the concave-convex molded sheet 5 shown in FIG. 5, a substantially quadrilateral through hole 5a is formed in the center, and the sheet members 5b to 5e are placed in front of the outer peripheral portion of the perimeter of the through hole 5a. It is formed in an inclined shape so as to be located, and a floral pattern is three-dimensionally formed on each of the sheet members 5b to 5e by unevenness. 6 (a) to 6 (d) show the molding process of the concave-convex molded sheet 5 by vacuum forming. That is, as shown in (a), the thermoplastic synthetic resin sheet 20 on which the figure is printed in advance is softened by heating with the heater 21, and then the breathable female mold is shown in (b). By vacuum-sucking 22, the thermoplastic synthetic resin sheet 20 is vacuum-sucked onto the molding surface of the female mold 22. As a result, the thermoplastic synthetic resin sheet 20 is formed into a square cone shape as shown in FIG. 5 following the molding surface, and at the same time, a floral pattern is formed unevenly on the entire thermoplastic synthetic resin sheet 20. Then, as shown in (c), the thermoplastic synthetic resin sheet 20 is separated from the molding surface of the female mold 22 by blowing air into the female mold 22, and then the thermoplastic synthetic resin sheet 20 is separated from the molded surface. By cutting the unnecessary portion with a Thomson mold and trimming it, the concave-convex molded sheet 5 is finished.

The concave-convex molded sheet 5 shown in FIG. 5 is integrally molded so as to have a square cone shape that expands at the front, but each sheet member 5b to 5e is molded separately, and each sheet member 5b is formed. By arranging ~ 5e in an inclined shape so that the outer peripheral portion is located in front of the central portion, a square cone shape may be formed. Further, it may be formed or arranged so as to have a round cone shape instead of a square cone shape. In short, the concavo-convex molded sheet 5 is arranged on the rear side of the game plate 3, and the concavo-convex molded sheet 5 is provided in an inclined shape in which the outer peripheral portion is located in front of the central portion. Therefore, it can be made to appear that there is a wide space and depth behind the game board 3.
Further, in the embodiment shown in FIG. 3, a slit-shaped opening 5f is formed in the seat member 5b on one side, and a character 5h that imitates a butterfly, for example, moves forward and backward by an electric actuator 5g on the back side of the seat member 5b. Is provided so that the character 5h can appear and disappear from the opening 5f to the front surface. By making the character 5h appear and disappear in accordance with the progress of the game in this way, the game is further excited.
In the embodiment shown in FIG. 3, an opening 5f is formed in one sheet member 5b, but a plurality of sheet members are arranged with a gap in the front and rear so as to partially overlap when viewed from the front. Then, the character 5h as described above may appear and disappear from the gap. By doing so, the back side is not completely exposed from the opening, and the design or the like can be continuously displayed without being interrupted by the opening.

The light emitting substrate 7 has a plurality of light emitting diodes 7a mounted on the front surface, and the front surface of the assembled plate 7c formed in a square cone shape in which a through hole 7b is formed in the center of the light emitting substrate 7 and expands toward the front. It will stop at. The diffusion sheet 6 is arranged in front of the light emitting substrate 7 and diffuses a point light source emitted from the light emitting diode 7a in a plane. The assembly plate 7c is housed in the assembly case 8, and a symbol variation display device 9 such as a liquid crystal is fitted into the assembly hole 8a formed in the center of the assembly case 8, and the assembly case 8 is fitted. It is screwed to the back surface of the game board 3. As a result, the light emitted from the light emitting substrate 7 hits the back surface of the concave-convex molded sheet 5 substantially uniformly, and the pattern formed on the concave-convex molded sheet 5 passes through the game plate 3 and is visible to the player from the front. At the same time, the display of the symbol variation display device 9 is visually recognized through the window hole 3a. A part of the concave-convex molded sheet 5 is also visually visible through the window hole 3a.

As shown in FIG. 7, the gaming board unit 1 configured in this way is incorporated into the gaming machine main body 10. Then, the player operates the launch handle 10a provided on the front surface of the game machine main body 10 to repel the game balls accumulated in the ball plate 10b, so that the game balls move upward along the ball guide rail 3g. The gaming ball flows down the gaming area inside the ball guiding rail 3g, and can win a prize in the variable winning opening 2b, the multiple winning opening 2c, or the like.
During such a game, characters, symbols, etc. are displayed on the symbol variation display device 9 according to the winning situation, and the display can be seen through the window hole 3a, and at the same time, the transparent or translucent game plate 3 is transmitted through the game board 3. Since the concave-convex molded sheet 5 can be seen, a pattern such as a floral pattern three-dimensionally displayed on the concave-convex molded sheet 5 can be seen almost entirely on the game board 3. Here, since the concave-convex molded sheet 5 is arranged on the rear side of the game plate 3 so as to gradually incline forward as it approaches the outer peripheral edge of the game plate 3, it is viewed from the player's point of view. It seems that there is a wider space and depth inside the game machine than it really is. Further, by blinking the light emitting diode 7a, the symbol formed on the concave-convex molded sheet 5 is transmitted through the game plate 3 to be seen more prominently and realistically, and the blinking of the light emitting diode 7a and the symbol variation display are displayed. By interlocking with the display of the device 9, the effect of the effect is further enhanced.

In addition to the floral pattern shown in this embodiment, the pattern formed on the concave-convex molded sheet 5 includes displaying fireworks, displaying the rocket surface that can be seen when entering a cave, and for space travel. You can make various attempts such as displaying the scenery seen from the window of the rocket when you go.
Further, as the molding method of the concave-convex molded sheet 5, in addition to the vacuum forming shown in the embodiment, the concave-convex molded sheet 5 may be molded by pneumatic molding in which a thermoplastic synthetic resin sheet is pressure-bonded to a molding die by air pressure. In any case, thermoforming can be realized by an inexpensive molding mold such as a plaster mold or a wooden mold and an inexpensive device so that a packaging container such as a disposable lunch box is molded. Therefore, injection molding is performed as in the conventional case. It does not require the manufacturing cost of the decorative body to be molded, and the cost can be significantly reduced. Therefore, by using a transparent or translucent synthetic resin gaming board, it is possible to manufacture an attractive ball gaming machine with excellent performance capable of producing a deep effect at low cost.

In this embodiment, the light guide plate 4 and the diffusion sheet 6 are provided, but the material for refracting and diffusing light in this way is appropriately provided according to the need for display and is not always required. For example, when the light emitting diode, which is a point light source, is to be displayed like a star shining in the night sky, the diffusion sheet 6 is not required. As described above, the light guide plate 4 and the diffusion sheet 6 are provided as needed in order to increase the effect of producing light, and it is also possible to provide an optical processing sheet other than that shown in this embodiment.
Further, a light source such as a light emitting diode may be provided on the back side of the front component 2 such as the center frame 2e or on the game plate 3 or the like, and the uneven molded sheet 5 may be illuminated from the front by the light source. In short, the arrangement of the light source is not limited to this embodiment and can be freely set.
