Description

  The present invention is provided inside a ball game machine such as a pachinko, an arrangement ball, and a sparrow ball, and game parts such as a game nail, a windmill, and a winning opening are provided on the surface, and the game ball flows down the surface. The present invention relates to a resin game board for allowing a player to see and enjoy the appearance of the game ball flowing down.

  Conventionally, a game board of a ball game machine is generally made of a wooden plywood (veneer), and a cell board (plastic thin board) on which a pattern such as a character is printed is attached. However, in recent years, a synthetic resin game board as shown in Patent Document 1 described below from the viewpoint that plywood is easily deformed and product defects are likely to occur, and environmental protection such as economy or recyclability is taken into consideration. Has been proposed. The game board is formed thick so that the game area corresponding to the inside of the guide rail can hold a nail portion such as a game nail (obstacle nail) or a windmill, and the non-game area outside the guide rail is thin. A synthetic resin game board which is molded and thereby has a high holding power of the nail portion in the game area and is lightweight can be provided.

  In addition, the game board shown in the following Patent Document 2 is formed of a transparent synthetic resin, and is roughened by laser processing or the like so that light can diffusely reflect on the back surface of the game area (a textured surface made of fine irregularities). The game board is assembled in the gaming machine so that the rough surface is irradiated with light from a light source such as a lamp or LED, and the rough surface shines when viewed from the front of the gaming machine, thereby providing a design effect. Is.

By the way, the game board shown in Patent Document 2 has a problem that it takes extra man-hours because it is necessary to post-process the rough surface with a laser processing machine or the like when manufacturing. In contrast to this, even if a manufacturing method in which a rough surface is formed in advance on the molding surface of the injection mold is considered, if such a fine uneven surface is formed on the injection mold, the resin is heated during molding. There is a problem that the gas generated by the decomposition tends to accumulate on the uneven surface, and a product defect called gas burning tends to occur. In addition, if the attached gas component is left in the mold, the uneven surface may corrode and the original uneven surface may not be reproduced, and if it becomes a fine uneven surface, it is troublesome to remove the attached gas component. There is a problem that necessitates maintenance.
In addition, the gaming board shown in Patent Document 2 does not provide a stage effect unless light is radiated on the rough surface, and if the board is not irradiated with light, the gaming board is merely a transparent plate and no design presentation is made. In order to produce a production effect, a large number of light sources such as lamps and LEDs are required, which increases the manufacturing cost, may cause an accident due to overheating of the light source, and increase power consumption. There was a problem.
The present invention is intended to provide a resin game board that can solve such problems.

Therefore, the resin game board of the present invention is a game board that is injection-molded with a colored transparent synthetic resin and has a flat surface and a plurality of steps formed on the back surface. The shade of the color visually recognized from the surface changes according to the thickness.
Further, in the resin game board according to the present invention, an opening for attaching a game component is formed in a penetrating shape, and the back surface is formed in a plurality of steps so that the wall thickness gradually becomes thinner or thicker as the distance from the opening increases. It is characterized by that.

  Further, the resin game board of the present invention is a game board that is injection-molded with a colored transparent synthetic resin, and has a continuous thickness while forming a flat surface on the back and a gently sloping surface. It is characterized by being gradually changed so that the shade of the color visually recognized from the surface changes according to the thickness.

  The resin game board according to the present invention is easy to manufacture by injection molding, and it is possible to provide a game board without providing a cell plate on the front surface or a light source such as a lamp or LED or a decorative part on the back surface. Since it can produce an interesting design-like effect, costs are reduced.

The perspective view of the back surface of the resin game board shown in FIG. 1 is a longitudinal sectional view of a resin game board according to the present invention. 1 is a longitudinal sectional view of a resin game board according to the present invention.

  Next, an embodiment of the present invention will be described with reference to FIGS. This resin game board 1 is a synthetic resin such as polycarbonate resin, ABS resin, acrylonitrile resin, etc., for example, a colored transparent synthetic resin such as blue is injection molded into a predetermined injection mold into a rectangular plate shape. It is integrally molded. A large opening 2 is formed by injection molding so as to penetrate the front and back sides. A large game part such as an electronic display or a center accessory (not shown) is attached to the opening 2. 3 is an opening formed in a front-and-back manner for attaching a gaming part such as a starting variable prize device to the lower part of the opening 2, 4 is for attaching a gaming part such as a large prize opening device to the lower part of the opening 2 Openings formed in front and back penetrations, 5 and 5 are openings formed in front and back penetrations for attaching game components such as a normal prize-winning device on both lower sides of the resin game board 1, and 6 is a game such as a passing chucker It is an opening formed in a front-and-back through manner for attaching a part. Further, an outer edge rib 7 is integrally formed on the outer peripheral edge of the resin game board 1 so as to be the same as the thickness (about 19 mm) of a conventional wooden game board.

  The front surface 10 of the resin game board 1 is formed flat by this injection molding, and the back surface 11 of the resin game board 1 is denoted by reference numerals 11a to 11f in order from the thickest part in FIGS. As shown, the wall thickness is changed into a plurality of steps. The thickest portion indicated by reference numeral 11a has a thickness of about 19 mm, which is the same as that of the outer edge rib 7. The thinnest portion indicated by reference numeral 11f does not wobble game nails or windmill nails driven from the surface. The thickness of about 10 mm is ensured so that it can be firmly fixed. A nail hole provided for inserting and fixing a game nail or a windmill nail on the surface 10 of the resin game board 1 is formed simultaneously with the injection molding of the resin game board 1. Alternatively, it may be formed by punching after injection molding.

  FIG. 4 shows a large number of game nails 12 attached to the game area 9a where guide rails 8, 8 are attached to the resin game board 1, and the game balls that are surrounded by the guide rails and driven along the guide rails flow down. A state in which the windmill 13 and the like are planted and the predetermined game parts are attached to the openings 2 to 6 is shown. Note that the outside of the guide rail 8 is a non-game area 9b in which no game ball is allowed to flow down, but the non-game area 9b can also be viewed by players in the same manner as the game area 9a. In the resin game board 1 in which the thickness of the colored transparent synthetic resin is changed as in this resin game board 1, the color that is visually recognized from the surface is naturally darker as the thickness is thicker. For this reason, the portion indicated by the uppermost reference numeral 11a is the darkest color (in this case, deep blue), and the color gradually decreases from the reference numeral 11b to the reference numeral 11e in the downward direction, and the lowermost reference numeral 11f is obtained. The part shown in the figure is the lightest color (in this case, light blue). In this way, the color of the game board 1 changes in multiple levels, so the game board 1 appears to have a depth. During the game, the game balls move around the surface of the game board 1 vertically and horizontally and flow down, so that the game balls appear to fly in a wide space, and a powerful effect appealing to the player's vision can be achieved. Moreover, since it looks like this without providing a light source such as a lamp or LED or a decorative part on the back of the gaming board 1, the manufacturing cost of the gaming machine can be reduced, and the light source can be overheated, contributing to power saving. In addition, the feeling of fatigue of a player who plays a game for a long time is reduced without fear of eye fatigue due to the flickering of the light source as in the case of production using a conventional light source. Moreover, since it is not necessary to form a conventional textured surface on the injection mold for molding the resin game board 1, molding is facilitated, and a cell board or the like having a pattern printed on it is attached. Since it is not necessary, the manufacturing cost is reduced.

In the embodiment shown in FIG. 5, the resin game board 1 is molded from a colored transparent synthetic resin in the same manner as in the above embodiment, and the openings 3 formed in the game area 9a as shown by reference numerals 11a to 11h. The back surface of the game area 9a of the resin game board 1 is formed in a plurality of steps so that the wall thickness gradually decreases as the distance from the game device increases. As shown in FIG. A state where 14 is attached with screws 15 is shown in a cross-sectional view. Reference numeral 12 denotes a game nail fixed on the surface of the game area 9a. At this time, by setting the color of the mounting flange portion 14a of the game component 14 to the same color tone as the resin game board 1 and the darkest color (colored and opaque), the resin game board 1 as the distance from the game component 14 increases. The game area 9a gradually becomes lighter in color at each stage, so that an interesting design effect can be achieved such that the game component 14 appears to float in the air.
In this embodiment, assuming that the non-game area 9b is not visually recognized by the player, the thickness is changed only for the game area 9a instead of the entire area of the resin game board 1, and the non-game area 9b is uniformly thin. Thus, the resin game board 1 is reduced in weight. Further, reinforcing ribs 16 connected to the peripheral outer edge ribs 7 are integrally formed on the back surface of the non-game area 9b so as to extend radially, and cylindrical portions 17 are formed in front and back through the four corners of the game board 1. The cylindrical portion 17 serves as an attachment hole for the gaming machine main body. As in this embodiment, it is possible to produce an expansive and interesting design effect by forming only the back surface of the game area 9a in a stepped shape.
Further, although not shown, the color of the mounting flange portion 14a of the game component 14 is the same color tone as that of the resin game board 1 and has the lightest density, and the wall thickness gradually increases as the distance from the opening 3 increases. By forming the back surface into a plurality of steps, the color visually recognized by the player during the game appears to gradually darken from stage to stage as the player moves away from the game component 14, so that the same interesting effects can be achieved. Can do.

  In the embodiment shown in FIG. 1, the boundary line in which the thickness of the resin game board 1 changes is made in a horizontal straight line. However, in the embodiment shown in FIGS. A wave that strikes the coast is imagined by making the line form a wave that runs in a horizontal direction at a constant pitch. By changing the shape of the boundary line where the wall thickness changes in this way, it is possible to create a wide variety of design effects that are reminiscent of a wide coastal landscape, clouds in the sky, or petals. .

  FIGS. 9 and 10 are longitudinal sectional views showing an embodiment of the resin game board 1 according to the third aspect of the present invention. The game board shown in FIG. 9 is injected with a colored transparent synthetic resin. The surface 10 is formed to be flat, while the back surface 11 is formed on a curved inclined surface that gently undulates to change the thickness of the game board 1 smoothly. Further, the resin game board 1 shown in FIG. 10 is injection-molded with a colored transparent synthetic resin to form the front surface 10 flat, while the back surface 11 is formed in a continuous shape while the flat inclined surface is refracted. Thus, the thickness of the game board 1 is changed gently. In this way, by forming the back surface 11 into a gently sloping surface and continuously changing the wall thickness, the shade of the color visually recognized from the front surface 10 also changes gently according to the wall thickness. Thus, even if the back surface 11 of the resin game board 1 is formed in a gently sloping surface, a fantastic and fascinating performance reminiscent of, for example, a sunset sky can be achieved without requiring a light source. .
