JP-A-2005-312471

  In the game board manufacturing method disclosed in Patent Document 1, an extruded synthetic resin plate is cut, and a cutting hole is provided to provide a mounting hole for a prize device or the like and a pilot hole for hitting a game nail. .

  However, this manufacturing method has a problem that the number of man-hours for cutting increases and the manufacturing cost increases accordingly.

The game board according to claim 1 is a game board formed by stacking m (an integer of 2 or more) synthetic resin plates each having a through-hole constituting hole, and the through holes are formed by stacking the synthetic resin plates. By connecting the hole-constituting holes, a mounting hole for attaching a winning device, a display device or a decorative part is formed as a through hole of the game board,
Each synthetic resin plate from the front surface of the game board to the nth ( an integer greater than or equal to 2 and less than or equal to m ) sheets is provided with a pilot hole constituting hole having a circular opening shape. A pilot hole for a game nail that is open to the front of the game board is formed,
The opening center of each prepared hole forming hole for forming one prepared hole on the front surface of the synthetic resin plate is upward on the front side of the game board with respect to a normal perpendicular to the surface of the game board And the game nails that are driven into the prepared holes are given an elevation angle α.

This game board has a board thickness suitable for a ball game machine equipped with m synthetic resin boards (m is an integer of 2 or more), for example, a board thickness of 19 mm.
Although the material of the synthetic resin plate is not limited, acrylic, polycarbonate, polyethylene, PET, ABS, and the like are suitable in consideration of the rigidity required for the game board. In addition, it is not necessary to use the same material for each synthetic resin plate. Acrylic with excellent scratch resistance is used for the parts that come into contact with the game balls, and inexpensive parts can be used for the parts that do not come into contact with the game balls. It is.

  The number m of laminated synthetic resin plates is determined by the thickness of the game board and the thickness of each synthetic resin plate (not necessarily the same thickness). For example, if a 19 mm thick game board is made using a 1 mm thick synthetic resin plate, m = 19. Similarly, even if it is a 19 mm thick game board, it can also be 2 mm × 9 + 1 mm × 1, 2 mm × 8 + 3 mm × 1, 3 mm × 5 + 4 mm × 1. Of course, a synthetic resin plate having a thickness of 1.5 mm or 2.5 mm can also be used.

The synthetic resin plate is provided with a through hole configured hole in each through hole is formed by communicating the through hole construction holes each other they are laminated each synthetic resin plate. This through hole is an attachment hole for attaching a winning device, a display device or a decorative part . Accordingly, a plurality of through holes are usually provided. Also, the shape of each through hole varies depending on the application. The out hole can also be formed as a similar through hole.

The through hole constituting hole provided in each synthetic resin plate to form a through hole to be a mounting hole may be formed when molding the synthetic resin plate by injection molding, injection compression molding, etc., extrusion molding, etc. For example, it may be formed by cutting by press working on the plate material manufactured in (1).

That is, the synthetic resin plate may be manufactured by injection molding, injection compression molding, extrusion molding or the like.
However, when the thickness of the synthetic resin plate increases, it becomes difficult to obtain a good one by injection molding or injection compression molding. Moreover, punching by press working becomes difficult. If it does so, it will cut into the board | plate material manufactured by extrusion molding, but this will become the same as the prior art.

Therefore, it is desirable to make the plate thickness applicable to cutting processing such as injection molding, injection compression molding or pressing, and specifically, it is 5 mm or less, preferably 3 mm or less.
Game board of claim 1, wherein the through hole by causing formed by laminating the through holes constituting hole provided with m (2 or more integer) pieces of synthetic resin sheet to each communicating the through hole constituting the hole together Therefore, there is no need to cut through holes, and the manufacturing cost can be reduced accordingly.

Further, in the gaming board according to claim 1, each synthetic resin plate from the front surface of the gaming board to the nth ( an integer of 2 or more and m or less ) number is provided with a pilot hole constituting hole having a circular opening shape. The prepared holes are connected to each other to form the prepared holes for the game nails that open to the front surface of the game board by the stacking, and each prepared hole for forming one prepared hole is formed. The opening centers of the front holes of the synthetic resin plates of the component holes are shifted from each other along a straight line of an elevation angle α that is upward on the front side of the game board with respect to a normal line perpendicular to the surface of the game board, An elevation angle α is given to the game nail driven into the pilot hole. Therefore, it is not necessary to cut the prepared hole for the game nail, and the manufacturing cost can be reduced accordingly.

The pilot hole for the game nail may penetrate the game board in the same manner as the through hole. In the game board according to claim 1, m ≧ 3, n ≦ (M-1) , and the prepared hole for the game nail may be a blind hole.

The game board according to claim 3, in claim 1 or 2 gaming machine according,
Any one or a plurality of the synthetic resin plates are provided with a decorative material accommodation opening penetrating the synthetic resin plate ,
The front and rear of the decorative material accommodation opening are closed by the synthetic resin plate adjacent to the synthetic resin plate provided with the decorative material accommodation opening .
Decorative material receiving aperture is Shun cut shaped notch or from the sides as well, provided through a synthetic resin plate. Since the inside of the decoration material accommodation opening becomes a space, the decoration material can be accommodated therein. Examples of the decorative material include a sheet or plate colored by printing or the like, a light emitter, a display, and the like. However, the decorative material is not limited thereto, and is not particularly limited as long as the decorative effect is exhibited.

The decorative material accommodation opening can be provided in any one or a plurality of synthetic resin plates.
Since the front and rear of the decoration material accommodation opening are closed by the synthetic resin plate adjacent to the synthetic resin plate provided with the decoration material accommodation opening, the decoration material accommodation opening, i.e., this As a result, there is a decorative material accommodated in the container, and the decorative effect is enhanced. Further, if the decorative material accommodation opening is sealed, particles, powder, liquid and the like can be used as the decorative material.

The game board according to claim 4 is the game board according to claim 3 , wherein a plate material different from the synthetic resin plate provided with the decoration material accommodation opening is fitted in the decoration material accommodation opening. It is characterized by.

  When a plate material different from the synthetic resin plate provided with the decoration material accommodation opening is fitted into the decoration material accommodation opening, it becomes the same as when a part of the synthetic resin plate is used as another plate material. In other words, the decoration effect is enhanced by making the appearance different from the synthetic resin plate such as the color and transparency of another plate.

Since the front surface of the game board is a game area, at least the game area is required to be flat. On the other hand, it is more convenient for the back surface of the game board to be flat rather than used for decorative purposes. Therefore, it is preferable that the decoration material accommodation opening is not provided in the synthetic resin plate forming the front surface of the game board and the synthetic resin plate forming the back surface.

Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.

Is displayed. Note that the display device is not integrated with the game board 1 (not part of the game board 1), and is attached to the back of the game board 1 in such a posture that the screen 16 faces the player. Yes.

  If the jackpot lottery is a win, the display showing the jackpot is performed on the display device (screen 16) following the symbol change display. When the jackpot display is made, the jackpot game is started and the jackpot 6 is opened. This display device is for effect display, and the result of the big win lottery is displayed by a special symbol display device (not shown) (for example, 7 segment LED), but whether the display device (screen 16) alone is a big hit or not. Can be determined.

  A guard rod 17 is attached to the game board 1 so as to correspond to the upper side of the screen 16. The guard rod 17 is installed in order to prevent a game ball from entering the front of the screen 16 (in order to prevent the game ball from impeding visibility through the front of the screen 16). Yes. A window decoration material 18 is attached so as to correspond to the lower side of the screen 16, and windmills 19 are arranged on the left and right sides of the window decoration material 18.

The guard rod 17 and the decorative material 18 under the window also serve to show the player the upper and lower limits of the screen 16 of the display device, but the windmill 19 shows the left and right limits, though not exactly.
As illustrated, a large number of game nails 20 are implanted in the game area 4.

  A game nail 20 is arranged as a so-called ceiling nail in the upper center of the game area 4 (above the guard rod 17), and as a so-called life nail just above the normal winning openings 7, 8, the start winning opening 13 and the passing opening 15, respectively. Has been. Further, below the left and right windmills 19 and the under-window decoration material 18, row-like game nails 20 are arranged so as to guide the game balls to the composite winning device 14 or the passage port 15. In addition, although there is a difference in arrangement density, the game nails 20 are appropriately arranged.

  The main body of the game board 1 is made of synthetic resin and is manufactured in the shape shown in FIG. The thickness of the main body of the game board 1 is uniform (19 mm in the present embodiment) except for a groove for dropping the game ball that has passed through the out hole 5 and a dowel hole for positioning (not shown). ).

  As shown in FIG. 2, the game board 1 is provided with mounting holes 6 a, 7 a, 14 a, 15 a and an out hole 5 for attaching the winning port unit 10, the composite winning device 14 and the passing port 15. Yes. In addition, a decorative pattern by the decorative material 27 is provided.

  As shown in FIG. 3, the above-mentioned game nail 20 is driven into the game board 1, and rail pins 21 for fixing the guide rails 2a and 2b are driven therein. In FIG. 3, only one game nail 20 and one rail pin 21 are shown in order to simplify the relationship between the game board 1 and the game nail 20, the rails 2 a and 2 b and the rail pin 21.

  As described above, the main body of the game board 1 is made of synthetic resin, but as shown in FIG. 4, a plurality (m pieces) of synthetic resin plates 30 are laminated. The synthetic resin plates 30 are joined to each other by a technique such as adhesion, welding, and polymerization adhesion.

  Acrylic, polycarbonate, polyethylene, PET, ABS or the like can be used for the synthetic resin plate 30, and a foamed material may be used other than the foremost synthetic resin plate 30 (the surface constitutes the game area 4). In addition, for example, the frontmost synthetic resin plate 30 that comes into contact with the game ball uses acrylic having excellent scratch resistance, and the inner synthetic resin plate 30 uses polycarbonate. You can also combine materials.

  Each synthetic resin plate 30 is provided with a through hole constituting hole 31, and through holes 32 such as mounting holes 6 a, 7 a, 14 a, 15 a and an out hole 5 are formed by communicating the through hole constituting holes 31 with each other. ing. The through-hole constituting hole 31 is provided by punching the synthetic resin plate 30 in a press process prior to lamination.

  In addition, the synthetic resin plate 30 from the front surface of the game board 1 is provided with a prepared hole forming hole 33, and the prepared hole forming holes 33 communicate with each other by lamination and are opened to the front surface of the game board 1. A pilot hole 34 is formed. However, some of the boards on the back side of the game board 1 are not provided with the prepared hole forming hole 33 (n <m), and the prepared hole 34 for the game nail is a blind hole. The pilot hole 34 is also provided at the same time as the through hole constituting hole 31 in the press working described above.

  In addition, although the opening shape of each pilot hole constituting hole 33 is circular and the diameter thereof is the same, the position of the axis Ca of the pilot hole constituting hole 33 is slightly different for each synthetic resin plate 30 as shown in an enlarged manner in the drawing. It is shifted one by one. This is because when the game nail 20 is driven, the angle of the game nail 20 is not perpendicular to the surface of the game board 1 but is set to an elevation angle α of about 4 degrees upward. That is, the position of the axis Ca of the prepared hole 33 is shifted from each other along the axis Cb of about 4 degrees upward with respect to the normal C perpendicular to the surface of the game board 1. The game nail 20 driven into the hole 34 is given an elevation angle α of about 4 degrees.

The pilot hole for the windmill 19 is the same as the pilot hole 34, and the shaft nail of the windmill 19 is given the same elevation angle α as the game nail 20.
On the other hand, the rail pin 21 (its pilot hole) is perpendicular to the surface of the game board 1.

  In addition, a decorative material accommodation opening 26 is provided in some of the synthetic resin plates 30 constituting the game board 1, and a decorative material 27 is fitted therein.

However, the synthetic resin plate 30 located on the front side of the decorative material 27 is transparent or translucent, and the synthetic resin plate 30 is made transparent. The coloring of the decorative material 27 can be observed through the watermark. Therefore, the decorative material 27 exhibits the same decorative effect as that of a known cell image. Moreover, since it exists in the inside of the game board 1, it has the decoration property different from the cell image which exists on the surface.

  The synthetic resin plate 30 in which the decoration material accommodation opening 26 is provided (the decoration material 27 is fitted) is not necessarily limited to one, and may be a plurality of sheets. In that case, a plurality of decoration materials 27 may be arranged so that a part or all of them overlap each other, and in this way, the decoration material 27 is arranged three-dimensionally and gives a sense of depth. Is obtained.

  The foremost synthetic resin plate 30 is the gaming area 4 and therefore needs to have a flat surface. However, the outermost guide rails 2a and 2b may be uneven if they are outside the gaming area 4. Therefore, the decoration material accommodation opening 26 may be provided in such a place, and the decoration material 27 may be fitted into the opening.

  As described above, the gaming board 1 according to the embodiment is formed by stacking m synthetic resin plates 30 each provided with the through hole constituting hole 31 and communicating the through hole constituting holes 31 with each other. A hole 32 is formed. The through hole 32 is an attachment hole 6a, 7a, 14a, 15a or an out hole 5 for attaching a winning device, a display device, a decorative part, or the like. Since this game board 1 has such a structure, it is not necessary to cut the through hole 32, and the manufacturing cost can be reduced accordingly.

  In the game board 1, the synthetic resin plates 30 from the front surface of the game board 1 to the nth (n <m) th are provided with pilot hole constituting holes 33, and the pilot hole constituting holes 33 communicate with each other by lamination. Thus, a pilot hole 34 for a game nail that opens to the front is formed. Therefore, it is not necessary to cut the pilot hole 34 for the game nail, and the manufacturing cost can be reduced accordingly.

In addition, the game board 1 is provided with a decorative material accommodation opening 26 in some of the synthetic resin plates 30.
A decorative material 27 is fitted there. When a plate material different from the synthetic resin plate 30 provided with the decoration material accommodation opening 26 is fitted as the decoration material 27 in the decoration material accommodation opening 26, a part of the synthetic resin plate 30 is used as another plate material. Be the same. The decoration effect is enhanced by making the appearance of the color and transparency of another plate (decorative material 27) different from the synthetic resin plate 30.
