Next, the operation of the variable prize winning device 1 having the above configuration will be explained. FIG. 9 is a front view of a pachinko machine equipped with the variable prize winning device 1. The variable prize winning device 1 is arranged approximately in the center of the gaming section surrounded by the guide rail 3 of the game board 2, and below it there are a plurality of starting prize winning devices for starting to change the display state of the variable display 40. A mouth 4 is provided. The variable prize winning device 1 usually includes a micro switch 69.
The actuator 70 has fallen into the groove 68 of the disk 61, and the motor 52 is stopped. On the other hand, the variable indicator 40 is stopped at the forward position shown by the solid line in FIG.

The special winning opening 32 and the general winning opening 33, 33 are hidden by a variable display 40 so that they cannot be seen from the front.

Further, any number from "O to 9" is displayed on the symbol display section 41 of the variable display 40.

In this state, if a ball hits any of the starting winning holes 4, the variable display 40 starts variable display on the symbol display section 41, and after a certain period of time, the variable display stops 6. Then, the display when stopped is The combination is a predetermined combination, for example 111
．． When certain numbers such as 333, 555, 777.999 are matched, a specific game state called a jackpot occurs, and the output signal first energizes the motor 52, and after a predetermined time, the solenoid 51.51 is energized.

When the motor 52 is energized, the drive gear 56 is rotated in the direction of the arrow in FIG. The disk 63 integrated with the driven gear 62 that meshes with the driven gear 56 rotates in the direction of the arrow in the figure, and the variable indicator 40 begins to move backward as shown by the chain line in FIG. 6 due to the crank movement by the interlocking rods 43a and 43b. And 5 yen!
61 and 63 rotate 180 degrees and the variable indicator 40 moves to the retracted position shown in FIG. 7, the actuator 70 of the microswitch 69 falls into the groove 68 of the disc 61 and the motor 52 stops. In this way, when the variable display device 40 moves to the retreat position, the special winning opening 32 and the general winning opening 3
3.33 appears on the bottom surface of the recessed chamber 31 and opens and closes the opening/closing member 14.
It is possible to win a prize by hitting a ball that is received on the 14th.

The open state shown by the solid line in the figure is changed to the open state where it is easy to receive a batted ball, as shown by the chain line in the figure.

The specific game state is 1. For example, while the opening/closing member 14.14 is opened and closed 18 times in a row, a batted ball that is received by the opening/closing member 14.14 and falls onto the slope portion 19 enters the specific winning hole 3.
2. When a winning ball is won and detected by the winning ball detector 34, from that point on, the opening/closing member 14.14 is opened and closed 18 times in succession again, and the cycle is updated with the 18 consecutive opening/closing members as one cycle. It is possible to do this up to 8 times.

When the specific game state ends, the motor 52 is started again by the output signal, and the discs 61 and 63 are rotated to 1
Rotate 80 degrees and stop. As a result, the variable display 4
0 moves forward from the backward position and stops at the forward position shown by the solid line in FIG. 6, returning to the normal gaming state.

In the above explanation, the so-called airplane type case is explained in which the opening/closing member is opened and closed a certain number of times as a specific game state. It may also be a so-called fibre-type game that can be opened and the above operation can be continued up to 10 times on the condition that a prize is won in a specific winning hole.
