Description

  The present invention relates to an improvement of a pachinko gaming machine having a resin game board.

  Conventionally, as shown in Patent Document 1, there is a pachinko gaming machine in which a large number of game nails are driven on a game board formed by molding a transparent synthetic resin. In order to hit a game nail on a game board made of synthetic resin, a pilot hole is formed in advance in the game board with a multi-axis drilling machine and the game nail is press-fitted into the pilot hole. Such a pachinko gaming machine is more effective in saving resources in that the synthetic resin used for the game board can be recycled as compared to a pachinko gaming machine having a conventional wooden plywood game board. In addition, by arranging an illumination device such as an LED behind the game board, it is possible to provide an attractive pachinko gaming machine with excellent performance. Such a pachinko gaming machine has a diamond cut or the like on the front or back surface of the game board so as not to directly show the structure of the lighting device or to diffuse light emitted from the lighting device in a complicated manner. It is common to form a design processing section. In addition, when the design processing unit is formed on the surface of the game board, the game ball falling on the game board is decelerated by coming into contact with the design processing unit having a large frictional resistance, so that the game nail and the board surface of the game ball Collisions with parts can be alleviated, and a secondary effect of improving the durability of pachinko machines is also obtained.

By the way, as shown in FIG. 6, in a pachinko gaming machine in which a game nail 119 is struck on a synthetic resin game board 111 having a design processing portion 111a formed on the surface side, the game nail is attached to a conventional wooden plywood game board. There is a problem that the game nail 119 is easy to break as compared with the pachinko gaming machine that has been hit. The reason for this will be explained in order. As shown in FIG. 6A, when the game balls collide with the game nail 119 because the contact distances u and v of the game nail 119 to the pilot hole 111b are not uniform. In addition, as shown in FIG. 6B, when the game nail 119 greatly vibrates in the shorter contact distance (v) and the game nail 119 returns to the vibration, the longer contact distance is obtained. The contact portion on the surface side of the game board 111 in (u) is shaved, and a gap 98 is formed between the prepared hole 111b and the game nail 119, as shown in FIG. 6C. Then, the cutting powder 99 accumulates in the gap 98, and the prepared hole 111b is worn by the cutting powder 99, so that the gap 98 becomes large. When the gap 98 increases, the holding force of the game nail 119 by the prepared hole 111b decreases, the vibration of the game nail 119 increases, and the game nail 119 breaks due to metal fatigue.

  Further, as shown in FIG. 7, the case where the game nail 119 is struck to the synthetic resin game board 111 having the design processing portion 111d formed on the back side is also shown in FIG. Thus, the contact distances x and y of the game nail 119 to the prepared hole 111b are not uniform. In the case of this configuration, with respect to the back side of the game board 111, the longer contact distance (x) has a longer contact distance, so that vibration of the game nail 119 is suppressed, while the shorter contact distance. In (y), the vibration of the game nail 119 is increased, and the contact portion on the back surface side of the game board 111 with the shorter contact distance (y) is scraped, and as shown in FIG. A gap 97 is formed between the pilot hole 111 b on the back side of the plate 111 and the base end of the game nail 119. Then, the shaving powder 99 accumulates in the gap 97 and the prepared hole 111b is worn by the shaving powder 99, so that the gap 97 becomes larger. When the gap 97 becomes large, the holding force of the game nail 119 by the prepared hole 111b decreases, the vibration of the game nail 119 increases, and the game nail 119 breaks due to metal fatigue.
