2a, 23a is opened, and opening / closing blade pieces 22b and 23b are opened when passing through the passage area 2b, and opening / closing blade pieces 22a, 22b, 23a and 23b are opened when passing through the passage area 2c. . For example, when a pachinko ball passes through the passing area 2a, a detection switch (not shown) provided in association with the passing area 2a detects the passing ball. In response to this, the solenoid 31a is excited. Therefore, the solenoid 31a attracts the plunger to rotate the lever 33a. Accordingly, the lever 34a
Since the short side of is pushed downward, the long side of the lever 34a rotates in the direction opposite to the center of the winning ball device 20.

In response to this, the slide supporting member 235 slides to the left of the guide hole 211. The sliding of the sliding support member 235 causes the pin 234 of the second opening / closing blade piece 23a to move to the left when viewed from the front.
33 moves diagonally upward along the guide hole 213.
As a result, the second opening / closing blade piece 23a is opened as if the user's hand was widened. At the same time, the lever 35a moves in accordance with the movement of the lever 34a, and the pin 224 of the first opening / closing blade piece 22a is rotated obliquely downward along the guide hole 219. Therefore, the first opening / closing blade piece 22a is also opened.

On the other hand, when a pachinko ball passes through the passage area 2b, the pachinko ball is detected by a detection switch (not shown).
Detected by. Accordingly, the solenoid 31b
Are excited, the right opening / closing blade pieces 22b, 23b are opened in the same manner as the opening operation of the left opening / closing blade pieces 22a, 23a. The guide part may be a receiving groove which is a groove having a bottom. The rod-shaped member may be a pin protruding from a predetermined link member, and the link member is rotated by moving the pin, and the opening / closing wing pieces 23a and 23b are opened and closed by the rotation. Good.

When a pachinko ball passes through the winning area 2c, a detection switch (not shown) detects the pachinko ball. In response to this, the solenoids 31a and 31b are excited. Therefore, the two pairs of open / close blades 22a, 22
b and 23a, 23b are opened as shown in FIGS. The solenoids 31a and 31b are provided on the back surface side of the mounting substrate and constitute an electric drive source for opening and closing the opening / closing blade pieces. Also, lever 3
3a, 33b, 34a, 34b, 35a, 35b and the pin 233 constitute a power transmission mechanism that transmits the drive of the electric drive source to the opening / closing member to open / close the opening / closing member.

If necessary, the left opening blade 22
The light emitting diode 27c may be caused to emit light when the a and 23a are opened, and the light emitting diode 27d may be caused to perform light emission and display when the right and left wing pieces 22b and 23b are opened.

Further, the conditions for opening only the left and right opening / closing wings, only the right opening / closing wings, or the left and right opening / closing wings are not limited to the above description, but various pachinko game machines can be used. It goes without saying that you can choose the conditions.

As described above, in this embodiment, two winning holes are provided so as to have a step on the upper and lower sides, and opening / closing wing pieces are provided on the left and right sides of the two winning holes, respectively, and the lower opening / closing wing pieces are provided. Is set to be larger than that of the upper side, so that the pachinko balls that enter the variable winning ball device 20 include those that enter the upper winning area and those that enter the lower winning area. Since the area of the ball received by the lower second opening / closing blade is much larger than the area of receiving the ball by the upper first opening / closing blade when opening the opening / closing blade of (see Fig. 3), Other winning areas 21a than the other winning areas 21a
The winning probability of b increases.

In the above-described embodiment, a case has been described in which a pair of open / close blades is provided on the left and right of a specific winning area and another winning area, but the technical idea of the present invention is not limited to this. Other various modified structures may be used. For example, the winning ball device is divided into left and right along the center line thereof, and the one including the left opening / closing wing pieces 22a and 23a and the first opening / closing drive mechanism 30a is arranged on the right side of the center of the game board, and the right side. What includes the opening / closing wing pieces 22b and 23b and the second opening / closing drive mechanism 30b may be provided on the left side of the center of the game board. Further, when the other winning area is composed of a plurality of winning openings, the total winning probability of the plurality of winning openings is made larger than that of the specific winning area 21a.

Further, as another modification, the number of prize balls to be discharged according to the winning balls may be larger in 21a than in the winning holes 21b. Also, 4 based on a certain game state
Alternatively, it may be determined that one opening / closing blade is opened and the opening / closing blade is closed according to the ball that has won the winning hole 21a. Such various driving methods can be appropriately selected according to the control method of the pachinko gaming machine.
