Reference numeral 4 denotes a set plate pivotally attached to a game board support frame by a hinge 5, reference numeral 6 denotes a winning ball collecting gutter provided on the back surface of the game board 1, and reference numeral 7 denotes a ball counting and paying device mounted on the set plate 4. The game board support frame has substantially the same thickness as the game board 1 in both the left and right frames 2 and the lower frame 3.

The lower frame 3 is a resin molded product having a structure as shown in FIGS. 2 and 3, in which three curved ball passages are integrally formed. The first is an overflow ball guide path 11 for guiding the overflow balls from the upper plate to the lower plate. The overflow ball guide path 11 guides the overflow ball flowing from the opening 12 on the upper surface of the lower frame 3 in the lateral direction through the hole 14 formed in the vertical wall, and extends vertically downward and has a slightly wide space 15. It is to be dropped from. A ball outlet 16 for deflecting the balls in the overflow ball guide path 11 in the lower dish direction is formed integrally with a lower portion of the space 15, and guides the overflow balls to the lower dish.

As shown in FIGS. 4 and 5, the overflow device 17 is provided by hollowing out the lower portion of the game board 1, and the prize / lending ball paid out from the ball counting and paying device 7 is placed on the upper plate 18. When the ball is full, an extra ball is dropped into the opening 12 from an overflow ball outlet path 19 opened downward. However, since the structure of the overflow device 17 itself is not a main part of the present invention, the description is omitted.

The second ball passage formed in the lower frame 3 is:
It is a bleed ball lead-out path 20 that bleeds balls from the ball piercing device to the back side of the pachinko machine. As shown in FIG. 1, the ball removing device 21 is installed near the ball counting and dispensing device 7,
This is a device for pulling out the balls stored in the portion from the upper ball tank 22 and the ball alignment rail 23 to the ball counting and dispensing device 7 to the back side of the pachinko machine at the hall side. The balls extracted from the ball extracting device 21 are set plate 4
It flows down via a bypass passage 24 formed in the inside.

As shown in FIG. 2 and FIG. 3, the bleed ball lead-out path 20 is a curved path formed adjacent to the overflow ball lead-out path 11 described above. The upper surface of the body 3 does not have an opening, and as shown in FIGS. 6 and 7, the lower part of the set plate 4 is hung so as to overlap the lower frame body 3 from the lower end side surface of the bypass passage 24. Accept the missing ball. The removed balls entering the removed ball outlet path 20 flow down in the vertical portion 25, and are discharged from the discharge port 26 at the lower end thereof to the back side of the pachinko machine.

The third ball passage formed in the lower frame 3 is:
This is a winning / non-winning ball discharge path 30 for discharging winning and non-winning balls from the gaming board 1 to the back side of the pachinko machine. The winning / non-winning ball discharging path 30 is provided with an opening 3 on the upper surface of the lower frame 3.

It is received from the lower part of the game board 1 into the opening 31.

These winning and non-winning balls are also discharged to the back side of the pachinko machine through the above-described discharge port 26. The winning and non-winning ball discharging path 30 crosses the overflow ball guiding path 11 on the way. Therefore, it does not fit inside the lower frame 3 having substantially the same thickness as the game board 1. Therefore, as shown in FIGS. 2 and 9, the lower half of the winning / non-winning ball discharge path 30 is formed by bulging a part of the lid 33, and the vertical section is formed at a position beyond the overflow ball guide path 11. 25, and the winning / non-winning ball is discharged to the back side of the pachinko machine from the discharge port 26 at the lower end. Therefore, only in the swelled portion, the thickness of the lower frame 3 exceeds the thickness of the game board 1.

As described above, the game board support frame of the present invention comprises:
An overflow ball guide path 11 for guiding the overflow balls to the lower plate inside the lower frame 3 having substantially the same thickness as the game board;
Pullout path 2 for pulling out balls to the back of the pachinko machine
0 and a winning / non-winning ball discharge path 30 for discharging a winning ball and a non-winning ball to the rear side of the pachinko machine. The overflow ball is shown in FIG. As shown in FIG. 6, winning balls and non-winning balls flow through these ball paths as shown in FIG.

The overflow ball is located in the space 1 described above.
5 is discharged to the lower plate from the ball outlet 16 at the lower end of the ball, but the player fills the inside of the overflow ball guide path 11 and the ball outlet 16 with neglecting to take out the ball from the lower plate at the time of a big hit. In this case, it is necessary to stop the ball counting and paying device 7. Therefore, a detection mechanism 40 for detecting that the ball is full is provided inside the space 15, but if the support member 41 is formed integrally with the lower frame 3 as shown in FIG. The assembly of the mechanism 40 becomes easy. In this embodiment, the detection mechanism 40 includes two valves 42 and 43, and the inside of the space 15 is filled with balls, and the two valves 42 and 43 are provided.
