Based on this, the special symbol of the special symbol display device 10 is changed, and then a predetermined symbol is fixedly displayed. When the quasi-special prize state occurs, the left and right movable pieces 12a, 12a of the special symbol start opening 12 are opened for a predetermined time, and the game ball can easily win the special symbol start opening 12.
[0013]
Here, FIG. 2 is a perspective view of the center accessory 20 described above.
The center accessory 20 includes a main body base 30 attached to the surface of the game board 2, a transparent plate 32 provided at the center of the main body base 30 to protect the special symbol display device 10, and a lower portion of the transparent plate 32. A warp passage formed by a stage surface 34 provided in the front view and extending in the left-right direction and a warp forming member 36 attached to the main body base 30 to guide the game ball received therein toward the stage surface 34. 38, a warp inlet 40 for receiving the game ball flowing down the left upstream of the game area 8 into the warp passage 38, and the game ball guided by the warp passage 38 from the front side of the left end of the stage surface 34 to the stage surface 34 and three specific inlets 44 (first, second and third specific inlets) arranged side by side in the center of the stage surface 34 in the left-right direction. 4a, 44b, 44c) and three specific outlets provided below the specific inlets 44a, 44b, 44c, respectively, for guiding the game balls that have entered the specific inlets 44a, 44b, 44c to the special symbol starting port 12, respectively. 46 (first, second, and third specific outlets 46a, 46b, and 46c). The first, second, and third specific inlets 44a, 44b, and 44c are formed with a size that allows one game ball to enter.
[0014]
The stage surface 34 is curved in a concave shape in the short direction, and has a surface shape that is continuous in a half-pipe shape in the left-right direction. The stage surface 34 also has a left-right direction from the stage surface on the left end side and the stage surface on the right end side. It is formed so that it gradually becomes lower toward the center stage surface.
FIG. 3 is an enlarged view of the vicinity of the first, second, and third specific inlets 44a, 44b, and 44c in a plan view, on the front side of the specific inlets 44a, 44b, and 44c. The substantially semicircular region is provided with a substantially planar guiding surface 50 that is inclined downward toward the specific inlets 44a, 44b, 44c.
[0015]
Here, the second specific inlet 44b located in the center in the left-right direction and the first specific inlet 44a located on the left side are partitioned by a partition member 54a rising from the guide surface 50. The second specific inlet 44 b and the third specific inlet 44 c located on the right side are also partitioned by a partition member 54 b that rises from the guide surface 50. The portions facing the guide surface 50 of the partition members 54a and 54b are provided with acute angle portions 54a1 and 54b1 as wedge shapes, and the game balls are in contact with the acute angle portions 54a1 and 54b1 by point contact. . In addition, although the slope provided in the partition members 54a and 54b in order to make it a wedge shape has faced the 1st specific inlet 44a and the 3rd specific inlet 44c in FIG. 3, both set the 2nd specific inlet 44b. You may provide so that it may face.
[0016]
A pair of protrusions 56a and 56b are provided on the guide surface 50, which is a front side region between the pair of partition members 54a and 54b. If the height of the protrusion is high, the game ball guided toward the specific inlets 44a, 44b, 44c may be retained by the protrusion. Therefore, the pair of protrusions 56a and 56b are at least lower than the center of the stage surface 34 in the left-right direction, which is the lowest position of the stage surface 34, and slightly protruded so that the rolled game ball can be picked up. Is set.
[0017]
As shown in FIGS. 3 and 4, the interval T between the pair of protrusions 56a and 56b is expressed as follows, where S is the interval between the acute angle portions 54a1 and 54b1 closest to the guide surface 50 of the pair of partition members 54a and 54b. The distance is slightly narrower than the distance S (T <S) and is smaller than the diameter D of the game ball. More specifically, when the diameter D of the game ball is 11 mm, the interval T between the pair of protrusions 56a and 56b is set to 10.8 mm.
[0018]
Next, a state where two game balls are about to enter the second specific entrance 44b at the same time will be described with reference to FIGS.
According to FIG. 5, the two game balls B1 and B2 that have rolled from the stage surface 34 to the guide surface 50 roll toward the second specific entrance 44b and try to enter at the same time. At this time, the two game balls B1 and B2 are in point contact with the acute angle portions 54a1 and 54b1 closest to the guide surface 50 of the pair of partition members 54a and 54b while riding on the pair of protrusions 56a and 56b, respectively. It remains stationary for a while.
[0019]
Here, the distance T between the pair of protrusions 56a and 56b is slightly smaller than the distance S between the pair of partition members 54a and 54b and smaller than the diameter D of the game ball B. Therefore, in FIG. The center of gravity G1 is closer to the center of the second specific entrance 44b than the right projection 56b, and the center of gravity G2 of the left game ball B2 is closer to the center of the first specific entrance 44a than the left projection 56a. It becomes the position. In such a state, the right game ball B1 rolls while pushing the left game ball B2 to the left, and the left game ball B2 enters the first specific entrance 44a and the right game ball B2 Enters the second specific inlet 44b.
[0020]
As described above, the two game balls B1 and B2 trying to enter the second specific entrance 44b at the same time remain stationary for a while, but they get on the pair of protrusions 56a and 56b to lose the balance of the center of gravity, so that both B1 , B2 immediately roll, one game ball B1 enters the second specific entrance 44b, and the other game ball B2 enters the first specific entrance 44a. Then, the game balls B1 and B2 that have entered the first and second specific inlets 44a and 44b exit from the first and second specific outlets 46a and 46b and fall toward the special symbol starting port 12.
[0021]
In FIG. 6, two game balls B1 and B2 riding on the pair of protrusions 56a and 56b are about to enter the second specific entrance 44b at the same time, and the center of gravity G1 of the right game ball B1 is The center of gravity of the game ball B2 on the left side is closer to the center of the first specific entrance 44a than the projection 56a on the left side. Yes. In such a state, the right game ball B1 rolls to the right to enter the third specific entrance 44c, and the left game ball B2 rolls to the left to cause the first It enters the specific entrance 44a. Thus, in the state of FIG. 6 as well, the two game balls B1 and B2 trying to enter the second specific entrance 44b at the same time remain stationary for a short time, but ride on the pair of protrusions 56a and 56b and have a balance of the center of gravity. When it collapses, it immediately rolls, one game ball B1 enters the third specific entrance 44c, and the other game ball B2 enters the first specific entrance 44a.
[0022]
Therefore, according to the present embodiment, the pair of protrusions 56a and 56b are provided on the front guide surface 50 between the pair of partition members 54a and 54b, and the interval T between the pair of protrusions 56a and 56b is set to the pair of partition members 54a. , 54b is set to be slightly smaller than the distance S between the acute angle portions 54a1, 54b1 closest to the guide surface 50 (T <S) and smaller than the diameter D of the game ball B. Even if two game balls B1 and B2 try to enter the second specific port 44b at the same time, the state is immediately released, and one of the first, second and third specific ports 44a, 44b and 44b is released. Each of the game balls B1 and B2 can be smoothly guided toward the player.
And since the retention of the game balls B1 and B2 in the vicinity of the second specific port 44b can be eliminated, the work burden of game machine management by the store clerk of the game store can be greatly reduced.
[0023]
