A hit ball whose center C2 coincides with that of the ball flowing down the lower ball transfer board 110 is most likely to win a prize. However,
When the operating portion 109 is operated with the driver 99 from this state, the operating shaft 104 rotates via the bevel gear 106 and the second bevel gear 107, thereby moving the mounting plate ioo in one direction. For this reason, the center CI of the winning area 53 and the specific winning opening 8
1 shifts from the center C2, and changes from a state where it is most easy to win a prize to a state where it is difficult to win a prize. Specifically, the winning rate to the specific winning opening 81 is controlled by adjusting within the range of the maximum deviation interval D3 (0.25 mm).

As described above, also in this second embodiment, the specific winning a prize opening forming members 80a, 80b are moved by the adjustment mechanism 103 to adjust the center C2 of the specific winning a prize opening 81 and the winning area 5.
By adjusting the positional relationship with the center c1 of 3, it is possible to change the winning rate of the winning balls (hitting balls; 11 mm in diameter) that are stopped by the movable members 58a and 58b into the specific winning opening 81. . Therefore, anyone can easily adjust the winning rate to the specific winning hole 81 without making sophisticated and delicate adjustments to the obstacle nails planted near the variable winning ball device 5o. .

In addition, in the second embodiment, since the mounting plate 100 and the specific winning a prize opening forming members 80a, 80b are moved integrally, there is an advantage that it is difficult for the player to notice that they have been moved. In addition, as a modification of this second embodiment, for example, the specific winning hole forming members 80a and 80b can be moved in the vertical direction,
Alternatively, the winning rate to the specific winning opening 81 may be changed by moving it back and forth. Furthermore, the center C2 of the specific winning opening forming members 80a and 80b is inclined within a predetermined angle range with respect to the center C3 of the winning area 53 to form the specific winning opening 8.
The winning rate for 1 may be changed.

Furthermore, it is also possible to prepare different materials for forming the specific winning opening forming members 120a and 120b and to replace them. For example, it is possible to prepare one made of polycarbonate and the other made of ABS resin, which have different numbers of bouncing threads for the hit ball, and by replacing them, the winning rate for the specific winning hole 81 can be changed. good.

In any of the above-described first to third embodiments, the specific winning opening forming member 80a.

Since 80b, 120a, and 120b are configured to be changeable, it is possible to change the winning rate of balls hit into the specific winning hole 81, and for this reason, the obstacle nail planted near the variable winning ball device 50 can be changed. Anyone can easily adjust the winning rate to the specific winning opening 81 without making sophisticated and delicate adjustments.

In addition, even if the structure changes the specific winning opening forming member in a manner different from the three embodiments described above, the specific winning opening 81
Any structure may be used as long as it can change the winning rate. For example, there are also ones where the winning rate changes depending on the attachment condition of the specific winning opening forming member.

The embodiments have been described above, and in the embodiments described above, the variable winning ball device 50 is provided with a pair of movable members 58a and 58b that open and close, but the invention is not limited to this, for example, The variable winning ball device may use a sliding piece that slides laterally or an opening/closing plate that opens and closes in the front and rear directions. In addition, as a winning ball device, the variable winning ball device 50 that changes between a state in which it is easy to receive a ball and a state in which it is difficult to receive a ball has been shown. The winning ball device may simply include a receiving area for receiving winning balls.

In addition, other variable winning ball devices or variable display devices may be activated when a ball hits a specific winning hole, and a right is generated when a ball hits a specific winning hole. Another variable winning ball device may be activated when a ball hits another winning hole. In addition, what is necessary is to operate the variable display device to operate other variable winning ball devices when the display becomes a predetermined display.

Furthermore, in the above-described embodiment, when a ball hits the specific winning hole 81 during the 18th opening/closing operation, the opening/closing operation of the movable members 58a, 58b is immediately stopped and the next opening/closing operation is started. As shown, the winnings to the specific winning opening 81 are memorized, and the next opening/closing cycle is started after a predetermined opening/closing cycle (10 winnings or 18 openings/closings) is completely completed. Good too.

In addition, in the first and second embodiments, the adjustment mechanism 83.103 was manually operated to change the specific winning hole 81, but this can be changed by, for example, an electric drive source such as a motor. It may also be configured to operate with. In this case, the change in the specific winning a prize opening 81 may be changed at the time of the operation, but the adjustment by the operation may become effective not at the time of the operation but after a predetermined period has elapsed. For example, when the number of starting winnings reaches a predetermined number (for example, 1000 times), the operated set value is activated. Also,
The operation means for manipulating the setting value is not a pinball game machine,
It may also be provided in a central control room of a gaming hall so that it can be operated remotely.

Furthermore, in the above-described embodiment, the pinball game machine is of a type in which the player throws borrowed balls into the hit ball supply tray 7 to play the game. It may also be a so-called card-type pinball game machine in which a game can be played by releasing the pressure sealed inside the machine.

Further, it may be a pinball game machine other than a pachinko game machine, such as an arrangement ball or an arebachi game machine.

[Effect of the invention] As is clear from the above explanation, the winning ball device of the pinball gaming machine according to the present invention has a specific winning opening formed by a specific winning opening forming member, and a special winning opening forming member. Since it is configured to be variable, it is possible to change the winning rate to a specific winning hole, and therefore, there is no need to make sophisticated and delicate nail adjustments of the obstacle nails planted near the winning ball device. , anyone can easily adjust the winning rate for a specific winning slot.
