  Since the game board 10 needs to hold the game nail 99 in its pilot hole, a certain thickness is required, and a decorative symbol display device, an electrical decoration device, and a control base unit are attached to the game board 10. Therefore, the mass of the game board 100 reaches about 30 kg. When manufacturing the pachinko gaming machine 500, the operator carries the game board 100 and fits it into the inner frame 300. Conventionally, since the game board was composed of beech and lauan plywood, its end surface was rough and had sufficient frictional force when carried, but when the game board 10 was composed of synthetic resin, its end surface was Since the game board 100 has a smooth surface and the mass of the game board 100 is large as described above, it is difficult to carry the game board 100, and the operator slides his hand when carrying the game board 100, and the game board 100 There was a risk of damage. An object of the present invention is to solve the above problems and provide a game board that is easy to carry.

The invention according to claim 1, which has been made to solve the above problems,
In a pachinko gaming machine having a game board in which a large number of game nails are driven on the surface of a game board made of synthetic resin,
A concave / convex processed portion that is recessed / protruded along the thickness direction is continuously formed in at least a part of the opposing end faces of the game board in a direction perpendicular to the thickness.

  The invention according to claim 2 is the invention according to claim 1, wherein the inner edge surface of the mounting opening formed in the center of the game board to which the decorative symbol display device is attached is recessed along the thickness direction. The protruding and recessed portions are continuously formed in a direction orthogonal to the plate thickness.

The invention according to claim 1 is a pachinko gaming machine having a game board in which a large number of game nails are nailed on the surface of a game board made of synthetic resin.
A concave / convex processed portion that is recessed / protruded along the thickness direction is continuously formed in at least a part of the opposing end faces of the game board in a direction perpendicular to the thickness.
For this reason, the concavo-convex processed portion becomes a non-slip, and the operator can easily carry the game board by holding the concavo-convex processed portion.

The invention according to claim 2 is the invention according to claim 1, wherein the inner edge surface of the mounting opening formed in the center of the game board to which the decorative symbol display device is attached is recessed along the thickness direction. The protruding and recessed portions are continuously formed in a direction perpendicular to the plate thickness.
For this reason, light diffuses in the concavo-convex portion, and the complicated internal structure of the decorative symbol display device is not visually recognized by the player, thereby improving the design.

1 is a perspective view of a game board showing an embodiment of the present invention. It is detail drawing of an uneven | corrugated processed part. It is explanatory drawing of the conventional game board. It is a perspective view of the state where the front frame of the pachinko gaming machine was opened.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, concave and convex portions 10 b that are recessed and protruded along the thickness direction are continuously formed in opposite directions of the game board 100 in the direction perpendicular to the thickness. For this reason, the uneven | corrugated processed part 10b becomes a slip stopper, and an operator can carry the game board 100 easily by holding the uneven | corrugated processed part 10b. As the shape of the concavo-convex processed portion 10b, for example, as shown in FIG. 2A, the concave and convex portion 10b is recessed along the thickness direction of the game board 10 in a V shape (in other words, protruded into a V shape). 2) A so-called V cut and a so-called ball cut that protrudes in an arc shape along the thickness direction of the game board 10 as shown in FIG.

  As described above, since the game nail 99 is press-fitted into the lower hole of the game board, the game board 10 is deformed by the amount of the press-fitting, and the outer edge of the game board 10 is expanded. In the present invention, since the uneven portion 10b is formed on the end surface of the game board 100, the deformation of the game board 10 due to the press-fitting of the game nail 99 into the prepared hole is absorbed in the space where the resin of the uneven portion 10b is not filled. Thus, it is possible to prevent the outer edge of the game board 10 from bulging. For this reason, the secondary effect that it becomes possible to attach the game board 100 to the inner frame 300 with high accuracy can be obtained.

  In the embodiment shown in FIG. 1, the concavo-convex portion 10 b is formed on both end surfaces in the width direction of the game board 10, but the concavo-convex portion 10 b may be formed on both end surfaces in the vertical direction of the game board 10. Absent. Further, the concave and convex portion 10b may be formed on a part of the opposing end surface of the game board 10.

  If the game board 10 is made of a transparent synthetic resin, the complicated internal structure of the decorative symbol display device or the electric decoration device is visually recognized by the player from the inner edge surface of the mounting opening 10a, which is not preferable in terms of design. Therefore, the concave / convex processed portion 10c is continuously formed in the direction perpendicular to the plate thickness on the inner edge surface of the mounting opening 10a so as to be recessed / protruded along the thickness direction, thereby diffusing light at the concave / convex processed portion 10c. Thus, the complicated internal structure of the decorative symbol display device and the electric decoration device is not directly seen by the player. The concavo-convex processed portion 10c includes, for example, the above-described V cut and ball cut. In addition, if the uneven | corrugated processed part 10c is formed in the end surface of the attachment opening part 10a, the deformation | transformation of the game board 10 by the press-fitting of the game nail 99 to a pilot hole will be absorbed in the space where the resin of the uneven | corrugated processed part 10c is not filled. Thus, it is possible to prevent the inner edge surface of the mounting opening 10a from bulging, and a secondary effect that the decorative symbol display device and the electrical decoration device can be mounted to the mounting opening 10a with high accuracy can be obtained. .

  In addition, since the uneven | corrugated processed part 10b and the uneven | corrugated processed part 10c are made into the shape which dents and protrudes along a plate | board thickness direction, the game board 10 was relatively arrange | positioned so that attachment / detachment with the said fixed mold and the said fixed mold was possible. When manufacturing by injection molding using an injection mold composed of a movable mold, the formation direction of the concavo-convex portion 10b and the concavo-convex portion 10c is such that the game board 10 is separated from the movable die or the fixed die. It is the same as the mold direction and is easy to release.

  Although the present invention has been described above in connection with the most practical and preferred embodiments at the present time, the present invention is not limited to the embodiments disclosed herein. It should be understood that pachinko gaming machines with such changes are also included in the technical scope, as long as they do not contradict the gist or concept of the invention that can be read from the claims and the entire specification.
