The configuration of the rotary prize-winning board 200 according to the first embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 2 to 4, the rotary winning board 200 is provided with a winning opening for selectively winning the game balls 100, and the winning opening includes an opening 201 opened in the rotating winning board 200, It comprises a shielding member 202 that closes or opens the opening 201.
Further, the rotary winning board 200 has a circular outer extension supported by a rotation support member 203 and can rotate in substantially the same plane as the game board 113. A driving source 204 for rotating the rotary winning board 200 is provided on the rotation support member 203, and the rotation support member 203 is fixed to the game board 113. The rotary winning board 200 is rotated by the drive source 204 while being guided by the rotation support member 203 via the drive mechanism.
The rear end portion 202b of the shielding member 202 is supported so as to be swingable about the rotation fulcrum 209 along the opening portion 201 of the rotary winning board 200, and the front end portion 202a of the gaming board 113 is supported. It is designed to rotate freely forward. However, the shielding member 202 is stopped at a position of a predetermined angle θ indicated by a chain line by a shielding member stopper portion 200b provided along the opening 201 of the rotary winning board 200.
Therefore, in the state where the rotary winning board 200 is shown in FIG. 2, the shielding member 202 rotates to the front of the game board 113 up to a predetermined angle θ by its own weight, and the opening 201 is opened.
In the state shown in FIG. 3 in which the rotary prize winning board 200 is further rotated halfway from the state shown in FIG. .
In this way, the rotary winning board 200 rotates so as to stop at two positions, that is, the open state position of the opening 201 shown in FIG. 2 and the closed state position of the opening 201 shown in FIG. Driven.

These two state positions will be described with reference to FIG.
FIG. 4 is a view of the rotary winning board 200 as viewed from the front of the game board 113. FIG. 4 (1) shows the same open state as FIG. 2, and the opening 201 is in the flow direction of the game ball. It is horizontally long and the shielding member 202 opens the opening 201.
4 (2) shows the same closed state as FIG. 3, and the rotary winning board 200 is rotated halfway from the state of FIG. 4 (1), and the opening 201 becomes horizontally long with respect to the flow direction of the game ball. A shielding member 202 closes the opening 201.

Therefore, in a state where the winning opening 201 is opened, as shown in FIG. 2, the game ball 100 flowing down from above the gaming board 113 is guided into the winning opening 201 with the inner surface of the shielding member 202 as a guide portion.

In a state where the shielding member 202 shown in FIG. 3 is blocking the winning opening 201, the shielding member 202 is simply suspended by gravity, so that the shielding member 202 is rotated forward of the game board 113 by some physical means. Although it is possible to move the game ball 100 flowing down from above, the game ball 100 is guided by the outer surface of the shielding member 202 and heads toward the lower out hole 122. Therefore, such a game ball 100 is won. It is almost impossible to flow into the mouth 201.
In addition, the shielding member 202 can be rotated only by a predetermined angle θ by the shielding member stopper portion 200b, and a game ball stopper portion 200a is formed on a part of the rotating gaming board 200 corresponding to the tip portion of the shielding member 202. Thus, even if the shielding member 202 is intentionally opened, it is impossible to make the game ball 100 win a prize opening 201.

In the first embodiment, in order to reliably rotate the shielding member 202 forward of the game board 113, as shown in FIG. It is possible to adopt a configuration in which the player itself is attached to the game board 113 so as to have a forward inclined posture having a predetermined angle α.
If comprised in this way, it can ensure that the shielding member 202 rotates by gravity ahead of a game board, and the risk that the shielding member 202 will not be in an open state in the game state in which a big prize opening is opened. Can be eliminated.
In order to place the rotary prize-winning board 200 in the forward leaning posture in this way, the same thing can be said even if the rotary prize-winning board 200 is attached in the forward leaning attitude when the rotary prize-winning board 200 is attached to the rotation support member 203. The effect is obtained.
Alternatively, as shown in FIGS. 6 and 7, a weight 207 is attached to the outer tip of the shielding member 202, or the center of gravity 208 is shifted from the rotation center 209 to the front of the game board 113 as shown in FIG. The same effect can be obtained even if the rotation center is set to.
