Specifically, in a state in which the opening and closing members 40 and 40 are substantially vertical, the opening and closing members 40 and 40 block the inflow ports 44 and 44, so that the prize winning device 3 cannot be won. That is, this state is a first state (closed state) that is disadvantageous to the player. On the other hand, in a state where the left and right opening and closing members 40 and 40 are pivoted in the direction away from the variable winning device 3 around the lower end portion, the opening and closing members 40 and 40 are opened to open the inflow ports 44 and 44. It will be in a state and it will be in the state where the winning to the variable winning apparatus 3 is possible. That is, this state is a second state (open state) that is advantageous to the player. In addition, when it is not a starting game state (in the case of a normal game state), the open / close members 40, 40 are kept closed (first state).

  The opening / closing members 40, 40 are predetermined by driving the big prize opening solenoid 40a in the starting game based on the establishment of the starting condition (here, the winning of the game ball to the first starting winning opening 4 or the second starting winning opening 5). In this manner, the state is converted to the second state, and a chance to win a prize winning device 3 is obtained. That is, based on the fact that the game ball won in the first start winning opening 4 is detected by the start opening sensor 4a, the opening and closing members 40, 40 are opened (converted to the second state), and after a predetermined time has passed (here, An opening operation in a predetermined manner is performed once such that the closing operation is performed again after 0.5 seconds have elapsed. Similarly, based on the fact that the game ball won in the second start winning opening 5 is detected by the middle start opening sensor 5a, the opening and closing members 40, 40 are opened in a predetermined manner (here, the opening time is 0.8 seconds). The opening operation is performed twice with a closing operation for a predetermined time (0.8 seconds here).

Under the opening / closing members 40, 40, for example, a passage hole 45 through which a game ball passes is formed.
In the passage hole 45, for example, a count sensor 45a (see FIG. 4) capable of detecting a passing game ball is provided. The count sensor 45a has a detection unit through which a game ball can pass, and outputs a detection signal when the game ball passes through the detection unit. The number of game balls won in the variable prize winning device 3 can be counted by counting the detection signal by the game control device 20. Further, based on this detection signal, a predetermined number (for example, 10) of winning balls are discharged from the discharging device.

Under the passage hole 45, for example, a rotation member 46 that has a passage opening through which a flowing game ball passes and distributes the flow path of the game ball after passage is provided.
The rotation member 46 is rotatable by a predetermined angle in each of the left and right directions by driving a rotation member drive motor 46M (see FIG. 4), for example, thereby changing the direction in which the game ball flows down. Be able to.
Note that the rotation angle of the rotation member 46 is detected by, for example, a position detection sensor 46a (see FIG. 4).

In addition, on the lower side of the rotation member 46, for example, an inflow path configuration portion 47 having a middle inflow path 471 through which game balls pass and left and right inflow paths 472 are provided.
For example, the middle inflow passage 471 is disposed substantially directly below the rotating member 46 and is formed so as to penetrate the inflow passage constituting portion 47 along a substantially vertical direction.
The left and right inflow passages 472 are provided, for example, on the left and right sides of the middle inflow passage 471, and are formed through the inflow passage constituting portion 47 so as to open to the left and right at substantially the same angle.
On the top surface of the inflow path constituting part 47, for example, an opening through which a game ball flows into each of the middle inflow path 471 and the left and right inflow paths 472 is formed, and the opening 472a of the left and right inflow paths 472 is It is larger than the opening 471a of the inflow channel 471.

  On the lower side of the inflow channel constituting portion 47, for example, an inclined surface portion 48 formed so as to be lower on the front side is provided. Thereby, the game balls that have flowed out from the outflow ports 471b and 472b of the middle inflow passage 471 and the left and right inflow passages 472 flow down the upper surface of the inclined surface portion 48 toward the front side.

On the lower side of the inclined surface portion 48, for example, a ball receiving portion 49 for receiving a game ball flowing down along the upper surface of the inclined surface portion 48 is provided.
For example, a specific area (specific winning opening) 491 having an opening through which a game ball can pass is formed in the approximate center of the ball receiving portion 49. The game ball that has passed through the specific area 491 is subjected to processing such as generation of a special game state based on detection by the specific area sensor 491a, for example.

On the lower right side of the ball receiving portion 49, for example, an outflow portion (not shown) for flowing out the game ball from the variable winning device 3 is provided. This outflow portion is provided with a remaining ball sensor 491b that detects an outflow game ball.
By detecting the game ball flowing out from the variable winning device 3 by the remaining ball sensor 491b and counting the detection signal by the game control device 20 described later, the number of game balls flowed out from the variable winning device 3 can be counted. It has become.

As described above, the game ball won in the variable winning device 3 is detected by the count sensor 45a provided in the communication hole 45b, and the variable winning is obtained by counting the detection signal from the count sensor 45a. The number of game balls won in the device 3 can be detected.
Therefore, in one start game, the number of game balls existing in the variable prize winning device 3 is obtained by subtracting the number of game balls detected by the remaining ball sensor 491b from the number of game balls detected by the count sensor 45a. Can be detected.

  In particular, when a game ball is not won in the specific area 491, it is confirmed by the remaining ball sensor 491b that all the game balls won in the variable prize winning device 3 have flowed out, and then the next start game can be performed. To do. Note that a sufficient time (for example, 1.5 seconds) for a game ball won from opening of the opening / closing members 40 and 40 to pass through the count sensor 45a is set as the count monitoring period, and the count sensor 45a is counted during this count monitoring period. If the game ball is not detected by the above, it is assumed that the next start game can be performed on the assumption that there is no winning in the variable winning device 3.
