Abstract

PROBLEM TO BE SOLVED: To solve the problem of a display device for a pachinko game machine: that while it tends to become large in size, enlargement of the display device has reached its limit because the size of the game board is standardized and difficult to increase; therefore, although there is the need to enlarge a mounting hole for the display device while maintaining the standard size of the game board, then the cross-sectional area of the game board across which the mounting hole extends must be reduced, resulting in reduced strength which may lead to deflection or cracking of the game board. SOLUTION: The game board 4 for a pachinko game machine has a mounting hole 20 bored in a game area to correspond to the display device 19. A plurality of game board component pieces 4a and 4b are formed which are separated from each other in such a manner as to extend across the mounting hole 20 of the largest size. The component pieces 4a and 4b are combined into one plate.

Description

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 ball game machine, such as a pachinko machine, a sparrow ball game machine, or a smart ball game machine, which shoots game balls to play a game.

[0002]

2. Description of the Related Art A conventional ball game machine will be described by taking a pachinko machine as an example. A game board for forming a game area is detachably mounted on the pachinko machine. A general game board has a decorative board made of a synthetic resin (for example, melamine resin) adhered to the surface of a wooden plywood, and changes the falling direction of a game ball in a game area surrounded by a guide rail in a circle. There are provided an obstacle nail, a winning device for receiving a game ball, a display device for performing a symbol matching game, and the like.

[0003]

The above-mentioned display device tends to become larger year by year in response to diversification and complexity of display contents. The display device has a mounting hole formed in the game board and is mounted in the mounting hole. The enlargement of the display device is directly linked to the enlargement of the mounting hole. On the other hand, the size of the game board is almost standardized, and it is difficult to expand the game board. Therefore, it is necessary to increase the size of the mounting hole while maintaining the standard size of the game board. However, if this is done, the cross-sectional area of the game board at a location crossing the mounting hole is reduced, and the strength is reduced. Since a decrease in the strength of the game board causes distortion and cracking, upsizing of the display device has almost reached the limit at present.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and is a game board for a ball game machine having a mounting area corresponding to a display device or a winning device in a game area,
Provided is a game board for a ball game machine in which a plurality of game board constituent pieces are formed by dividing the game board into pieces that cross the largest mounting hole, and the game board constituent pieces are combined to make one piece.

[0005] The strength of the game board is the weakest on the line across the largest mounting hole. Therefore, if the game board is divided in advance on the line, no distortion or crack occurs. Therefore, since the mounting hole can be greatly expanded without changing the size of the game board, the size of the display device and the winning device can be increased accordingly.
