[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine for playing by predicting in which ball hole the ball will be inserted by immersing the ball in a ball hole provided around a rotary disk. is there.

[0002]

2. Description of the Related Art As a conventional game machine of this type, for example, a roulette 1 as shown in FIG. 6 is generally known.

In such a roulette wheel 1, different numbers are given to the periphery of a substantially disk-shaped disc surface 2 which is inclined at a predetermined angle so as to have a conical shape with the central portion as the highest portion. The bottom holes 3 ... Are formed.

A decorative blade 4 is integrally fixed to the center of the upper portion of the board surface 2. Then, the board surface 2 rotates in one direction with respect to the base 5, so that the ball 6 thrown onto the board surface 2 is sunk into any of the surrounding bottomed holes 3.

The player plays by predicting which bottomed hole 3 the ball 6 will immerse into.

[0006]

However, in the conventional roulette 1 as described above, since the board surface 2 rotates in one direction and the ball 6 is only immersed in one of the bottomed holes 3, There was a problem that the movement locus of 6 was monotonous and lacked in fun.

Moreover, there is a problem that the ball 6 thrown into the board surface 2 may be able to be immersed in the predetermined bottomed hole 3 due to accumulated experience.

Therefore, the present invention provides a ball game machine that complicates the trajectory of the ball and gives randomness to the probability that the ball will sink into each bottomed hole, thereby intriguing the player. The task is to do.

[0009]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a plurality of bottomed holes are formed around a disk-shaped rotary disk, and the rotary disk is formed on the rotary disk.

And an internal gear that is meshed with the transmission gear and is rotatable around the rotation drive shaft around the transmission gear, and the ball striking means is provided at the tip of the rotation drive shaft. The ball game machine according to claim 1, characterized in that, while being fixed and rotated, the rotary disk is fixed to the internal gear and is rotated in the reverse direction with respect to the hitting means.

According to the third aspect of the present invention configured as above, when the drive actuator rotates the rotary drive shaft, the pinion gear rotates the transmission gear. The rotation of the transmission gear causes the internal gear, which is rotatably arranged around the rotation drive shaft, to rotate.
