  Here, the intermediate ball outlets 50c and 50d formed on the guide cylinder 50 are discharged to the rotating spiral rotor 60 so that the game ball B in the spiral passage 60a can be discharged as shown in FIG. As shown in FIG. 10, the possible position and the game ball B in the spiral passage 60a are alternately switched to a non-dischargeable position where the game ball B cannot be discharged.

  That is, as shown in FIG. 9 and FIG. 10, when the spiral rotator 60 rotates, the spiral passage 60a also rotates, and of the trajectory of the game ball B in the spiral passage 60a, the trajectory portion on the midway ball outlet 50c, 50d side. 9 is displaced in the vertical direction, as shown in FIG. 9, if substantially the whole ball outlets 50c, 50d are located outside the outer periphery of the track portion, the ball outlets 50c, 50d become dischargeable positions. As shown in FIG. 10, if substantially the entire ball outlets 50c and 50d are not positioned outside the outer periphery of the track portion, the ball outlets 50c and 50d are in the undischargeable positions.

The effect of the ball guidance device 16 will be described.
The game ball B that has entered the inside of the guide cylinder 50 from the ball inlet 50a falls while rotating on the spiral passage 60a in contact with the upper surface of the spiral portion 62 and the inner peripheral surface of the peripheral wall 51. The body 60 rotates and hence the helical passage 60a also rotates.

  Here, regarding the falling speed of the game ball B in the spiral passage 60a, compared to the case where the spiral rotary body 60 stops rotating, the spiral rotary body 60 rotates in the same direction as the rotation direction of the game ball B. The lower the speed, the lower the rotational speed of the spiral rotating body 60 in the same direction, and the slower the spiral rotating body 60 rotates in the direction opposite to the direction of rotation of the game ball B. The higher the speed, the higher the rotational speed of the spiral rotating body 60 in the reverse direction.

  The game ball B in the spiral passage 60a is alternatively discharged from the lower ball outlet 50b and one of the two intermediate ball outlets 50c and 50d to the outside of the guide cylinder 50. The game ball B discharged from the lower ball outlet 50b is smoothly transferred to the first rolling surface 45, smoothly rolls on the first rolling surface 45, and enters the winning guide section 40, that is, the upper start. The possibility of winning a prize opening 10a increases.

  On the other hand, the game ball B discharged from the middle ball outlet 50d falls to the stage 15 from above and is greatly changed in the behavior of the game ball on the stage 15 than when discharged from the lower ball outlet 50b. The possibility of entering the winning guide section 40 is reduced, and the game ball B discharged from the halfway ball exit 50c falls to the stage 15 from above as compared with the case where the game ball B is discharged from the halfway ball exit 50d. Since the behavior of the game ball on 15 changes more greatly, the possibility of entering the winning guidance section 40 becomes lower.

  As described above, according to the ball guidance device 16, since the guide cylinder 50, the spiral rotating body 60, the rotation driving mechanism 70, and the main control device 21 are provided, the game ball B rotates in the spiral passage 60a. In this case, it is possible to enhance the player's interest by performing a unique ball guidance in which the spiral rotating body 60 (that is, the spiral passage 60a) also rotates.

  Moreover, two intermediate ball outlets 50c and 50d formed so as to communicate with the spiral passage 60a are provided in the middle in the height direction between the upper ball inlet 50a and the lower ball outlet 50b of the guide cylinder 50, Since the game ball B in the passage 60a is configured to be discharged from the lower ball outlet 50b and one of the two intermediate ball outlets 50c, 50d to the outside of the guide cylinder 50, the spiral ball 60a The game ball discharge position for discharging the game balls B to the outside of the guide cylinder 50 can be changed in the height direction.

  The intermediate ball outlets 50c and 50d are alternately switched to a dischargeable position where the game ball B in the spiral passage 60a can be discharged and a non-dischargeable position where the game ball B in the spiral passage 60a can be discharged. Since it was comprised, the structure which discharges | emits the game ball B in the spiral channel | path 60a alternatively from any one of the lower ball exit 50b and the two middle ball exits 50c and 50d with rotation of the spiral rotary body 60. Can be realized reliably.

  A guide cylinder 50 and a spiral path 60a therein are provided in at least a part of the warp passage 55 that guides the game ball B to the stage 15, and the lower ball outlet 50 b of the guide cylinder 50 is the first rolling surface 45 of the stage 15. Therefore, when the game ball B is guided to the stage 15 through the warp passage 55, the unique ball guidance can be performed. When the game ball B in the spiral passage 60a is discharged from the lower ball outlet 50b, it is easy to enter the winning guide portion 40 from the first rolling surface 45 of the stage 15, and is discharged from the intermediate ball outlets 50c and 50d. In this case, it is difficult to enter the winning guide section 40, so that the probability that the game ball B guided by the warp passage 55 enters the winning guide section 40, that is, the winning rate for winning in the upper start winning opening 10a is changed. can do.

  Since the main control device 21 controls to change at least one of the rotational speed and the rotational direction of the spiral rotating body 60, the rotational speed and the falling speed of the game ball B in the spiral passage 60a can be changed. It can be expected that the game ball B in the spiral passage 60a is easily discharged from the midway ball outlets 50c and 50d as the speed is decreased.

  In addition, various modifications other than the disclosed items can be added and implemented without departing from the spirit of the present invention. For example, the number (one or more), the shape, the size, the arrangement, and the like of the intermediate ball exit can be changed as appropriate. The present invention also provides various ball guidance devices for guiding the game ball B, for example, guiding the game ball B not to the stage 15 but to various winning holes, or to other than the vicinity of the winning hole. The present invention can also be applied to a ball guidance device.
