Description

  The present invention relates to a structure of a center accessory device that is provided so as to surround the periphery of a display device in a pachinko gaming machine in which a large display device such as a liquid crystal is provided in the approximate center of a game board.

In recent years, pachinko machines tend to have a large liquid crystal display device of 8 inches to 10 inches or more in the center of the game board from the viewpoint that powerful performance is required. As the display device is increased in size as described above, the center frame member surrounding the display device is also increased in size. For this reason, the game area of the game board where game balls can flow down is relatively limited, making the game balls move dynamically and allowing the player to watch and enjoy the movement of the game balls. There was a problem that the real pleasure of this was spoiled.
Under these circumstances, windmill nails (a windmill-like rotating body fixed to the gameboard surface by a nail so as to be freely rotatable) are provided on both sides of the center frame member on the game board, and the windmill nails are blown away by the windmill nails. A pachinko gaming machine is known in which a game ball is guided to the lower side of a display device, and the lower side of the display device is effectively utilized as a game area.
By the way, with the board configuration as described above, it is becoming increasingly difficult to adjust the flow of the game ball with only the nail. In addition, since the game ball that hits the windmill nail is spun, even if it hits the ball guide member, it often spills off the inclined upper edge of the ball guide member and goes out of the center frame member. However, there is a problem that the lower game area of the display device cannot be used effectively.

In addition, the accessory in the pachinko machine shown in the following Patent Document 1 is such that the speed of the game ball is suppressed by forming a groove in the bowl-shaped passage of the game ball. The pachinko gaming machine shown in No. 3 was designed to make it easy to win a ball at a winning opening by providing a ball speed reducing means in the passage of the center role.
