Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a game board of a ball game machine that launches a game ball and plays a game, such as a pachinko machine, a sparrow ball game machine, and a smart ball game machine.
[0002]
[Prior 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 attached to the pachinko machine. A common game board is made by attaching a decorative board made of synthetic resin (for example, melamine resin) to the surface of a wooden plywood, and changes the falling direction of the game ball to a game area circled by a guide rail. A obstacle nail, a winning device for receiving a game ball, a display device for playing a symbol matching game, and the like are provided.
[0003]
[Problems to be solved by the invention]
The display device tends to increase in size year by year in response to diversification and complexity of display contents. The display device is provided with a mounting hole in the game board and mounted in the mounting hole, and an increase in the size of the display device directly leads to an increase in the size of the mounting hole. On the other hand, the size of the game board is almost standardized and is difficult to expand. Therefore, it is necessary to enlarge 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 the location crossing the mounting hole is reduced and the strength is lowered. Since the reduction in the strength of the game board causes distortion and cracking, the enlargement of the display device has almost reached its limit.
[0004]
[Means for Solving the Problems]
The present invention has been made in view of the above, and in a game board for a ball game machine in which a display device and a winning device are provided in a game area,
Said display device a winning device under the game board configuration pieces of the upper and the two-divided manner across both horizontal low intensity portions of the large mounting hole of a corresponding and most width in the mounting hole sac Chi before Symbol display device corresponding to the A game board component piece of
On the other hand, the display device is provided with a front flange contacting the surface around the mounting hole of the upper game board component piece and the surface around the attachment hole of the lower game board component piece,
A game board for a ball game machine in which the display device is attached to either one of the upper or lower game board constituent pieces and the upper and lower game board constituent pieces are sequentially attached to the ball game machine and tailored into one piece. I will provide a.
[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 cracking occurs. Therefore, since the mounting hole can be greatly expanded without changing the size of the game board, the display device can be enlarged accordingly.
[0006]
First Embodiment of the Invention
Embodiment 1 of the present invention will be described below by taking a pachinko machine as an example. 1 is an exploded perspective view of the pachinko machine, and FIG. 2 is a front view of the pachinko machine.

The front frame 3 has a frame shape having a large window hole 6, and an openable / closable glass door frame 7 covering the window hole 6 and a front plate 9 with a ball tray 8 are axially attached to the front side of the front frame 3. On the other hand, on the back side of the front frame 3, a ball launch plate 10 that is a support base of the ball launch unit is formed at a position facing the front plate 9, and a frame 11 is projected along the upper left and right sides of the window hole 6. ing.
[0008]
The game board 4 is located between the frame 11 and the mechanism plate 5 and is attached to the front frame 3 by a fixing means by a combination of a mounting shaft 12 protruding from the frame 11 and a fastener 13 provided on the mechanism plate 5. . In this attached state, the lower side of the game board 4 rests on the ball launch board 10, and the front face of the ball launch board 10 and the front face of the game board 4 are flush with each other. In addition, a guide rail 15 is attached to the front side of the game board 4, and a circular portion surrounded by the guide rail 15 becomes a game area 16. The game area 16 of the game board 4 is provided with a number of obstacle nails 17 that change the falling direction of the game ball, a winning device 18 that receives the game ball, a display device 19 for playing a symbol matching game, and the like. . In FIG. 1, reference numeral 14 denotes a through hole formed in the game board 4, and the mounting shaft 12 of the fixing means passes through the through hole 14.
[0009]
Therefore, the game board 4 has a combination structure of two game board components 4a and 4b as shown in FIG. That is, each game board component piece 4a, 4b has a form in which the game board 4 is vertically divided into two at the position crossing the mounting hole 20 of the display device 19, and both match to form one game board 4. . The obstacle nail 17 and the winning device 18 in the game area 16 may be directly attached to the respective game board component pieces 4a and 4b, and the guide rail 15 is divided vertically at the joint of the game board component pieces 4a and 4b. Are attached to each game board component piece 4a, 4b. The guide rail 15 may be attached to the auxiliary plate by protruding an auxiliary plate (not shown) from the front frame 3 so as to contact the front side of the game board 4. On the other hand, the display device 19 may be attached to either the lower game board constituent piece 4a or the upper game board constituent piece 4b, and does not need to be fixed to the other. In the first embodiment, the display device 19 is attached to the lower game board constituting piece 4a.
