DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game board for a pachinko game machine, and has a concave recess with an open rear surface on the back of the game board, and guides a pachinko ball received in a winning port to a winning ball collecting gutter. The present invention relates to a game board of a pachinko game machine in which a guide groove is provided to eliminate a need for a guide gutter member as a separate component, thereby simplifying a manufacturing process.

[0002]

2. Description of the Related Art Conventionally, for example, a game board is mounted on a pachinko game machine. A game area surrounded by a circular guide rail is formed on the front surface of the game board, and board parts such as a general winning opening, a variable winning opening, as well as many obstacle nails and windmills are mounted on the game board in the game area. Have been. Then, the pachinko balls that have won the general winning opening and the variable winning opening are guided to the back side of the game board, flow down in the guiding gutter member attached as a separate member to the back of the game board, and are positioned below the game board. It has been led to the winning prize ball gathering gutter. As the guide gutter member, a thin metal plate formed in an L-shape or a synthetic resin material formed in an L-shape or a U-shape is selectively used depending on the mounting position thereof, and is further fixed by screws. It had been.

[0003]

However, in the game board of the pachinko gaming machine, if the content of the normal game, that is, the model is different, the mounting positions of the general winning opening and the variable winning opening are often different. Therefore, it is necessary to manufacture many L-shaped or U-shaped guide gutter members adapted to each model, and since the mounting is performed with screws, these mounting operations are extremely troublesome, and the manufacturing process of the game board is difficult. It was complicated. In addition, there is a problem that the number of the guide gutter members is increased without difficulty and inventory management is becoming difficult. Therefore, the present invention has been made to solve the above problems, and can eliminate the need for a guide gutter member, thereby simplifying the manufacturing process of the game board and reducing the manufacturing cost.
Still another object of the present invention is to provide a game board in a pachinko game machine that can facilitate inventory management.

[0004]

In order to achieve the above object, a game board of a pachinko game machine according to the present invention has a game area formed on the front face thereof, and obstacle nails, windmills and general prize holes, variable prize holes are formed in the game area. In a game board equipped with a board component such as the above, a guide groove is provided on the back surface of the game board to guide the pachinko ball that has won the winning port to a winning ball collecting gutter located below the game board. The guide groove is formed in a concave shape with an open rear surface, and has a depth at which a pachinko ball can flow down. Further, a cover member is attached to the back surface of the game board so as to cover the guide groove. In this way, by providing the guide groove directly on the back surface of the game board, the guide gutter member attached as a separate member in the related art becomes unnecessary, so that the manufacturing process of the game board is simplified and inventory management becomes easy. Things.

When the game board is a wooden plywood, a guide groove is easily and quickly provided by cutting a router under computer control. At this time, when the part which is driven into the game board which is the spindle of the obstacle nail or the windmill is in the way, the thickness of the game board is at least the spindle of the obstacle nail or the windmill and is driven into the game board. It is desirable to form it thicker than the sum of the size of the recessed portion and the guide groove. When the game board is made of synthetic resin, the guide groove is integrally formed by a mold. Preferably, the cover member is detachably attached to the game board for maintenance and inspection.
