According to a second aspect of the present invention, in the gaming machine according to the first aspect, the ball receiving surfaces formed on the pair of movable wing pieces are different from each other with respect to a plane parallel to the central axis direction of tilting. The technical feature is that the direction is inclined.

In the gaming machine according to the second aspect, since the ball receiving surface has the inclination in different directions, forces acting in different directions are applied to the respective game balls on the ball receiving surface. As a result, the game balls can be deviated between the game board and the glass plate, so that each game ball can be smoothly guided to the opening.

According to a third aspect of the invention, in the gaming machine according to the first or second aspect, the width of the ball receiving surface is technically characterized by being larger than the diameter of the game ball.

In the gaming machine according to the third aspect, since the width of the ball receiving surface is larger than the diameter of the game ball, the game ball can be freely moved in the width direction of the ball receiving surface. As a result, the game balls can be deviated between the game board and the glass plate, so that each game ball can be smoothly guided to the opening.

According to a fourth aspect of the present invention, in the gaming machine according to any one of the first to third aspects, a technical feature is that the front surfaces of the pair of movable wing pieces are symmetrical.

In the gaming machine according to the fourth aspect, since the front surfaces of the pair of movable wing pieces are symmetrical to each other, the pair of movable wing pieces can be attached at symmetrical positions about the opening. For this reason, the constituent members of the winning device other than the ball receiving surface can be formed symmetrically, so that the design of the winning device can be harmonized.

According to the invention of claim 5, an opening for guiding the winning game ball to the back surface of the game board and a ball receiving surface for guiding the game ball to the opening are formed by a pair of structures sandwiching the opening. A gaming machine comprising a winning device having a tiltable movable wing piece, wherein the pair of movable wing pieces are formed in different shapes.

In the gaming machine according to claim 5, since the movable wing pieces have different shapes, when the pair of movable wing pieces are opened,
Even if the game spheres enter the movable wing pieces at the same time, these game balls flow down along the ball receiving surfaces of the movable wing pieces having different shapes, which causes a difference in the flow-down speed. As a result, even if the movable wing pieces start to close when each game ball wins, each game ball is sandwiched at positions displaced from each other, so that it can be smoothly guided to the opening. Therefore, it is possible to prevent the occurrence of ball clogging.

According to a sixth aspect of the invention, in the gaming machine according to any one of the first to fifth aspects, the pair of movable wing pieces are opened and closed by a single drive source via a link mechanism. It is a technical feature.

In the gaming machine of the sixth aspect, the pair of movable wing pieces are opened and closed by a single drive source. That is, since the ball receiving surfaces are asymmetrical with each other, it is possible to simultaneously open and close each movable wing piece, so that it is possible to use a single drive source. Thereby, the manufacturing cost can be reduced and the productivity can be improved.

However, the inclination of the ball receiving surface of the first embodiment with respect to the plane parallel to the left movable wing piece support shaft 72 (right movable wing piece support shaft 74) is, as shown in FIG. As the ball receiving surface 55 is advanced toward the side 54b, the inclination of the ball receiving surface 55 is increased and the inclination of the ball receiving surface 57 is increased, whereas in the modified example, the left movable wing piece of the ball receiving surface is increased. The inclination with respect to the plane parallel to the support shaft 72 (right movable wing piece support shaft 74) is, as shown in FIG.
From the bottom to the base portion side 54b, the degree of lowering of the inclination of the ball receiving surface 55 is increased, and the degree of increasing the inclination of the ball receiving surface 58 is decreased. In the modified example of the first embodiment, the same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 10 showing the structure of the modified movable wing piece, a ball receiving surface 55 is formed above the left movable wing piece 54, and a ball receiving surface is formed above the right movable wing piece 56. A surface 58 is formed. Below the surface of the left movable wing piece 54, a left movable wing piece support shaft 72, which is a central axis of tilting, is formed.
A right movable wing piece support shaft 74 which is a central axis of tilting is formed below the surface side of the right movable wing piece 56. The left movable wing piece support shaft 72 and the right movable wing piece support shaft 74 are fixed to the variable winning device 50 (see FIG. 3). A left movable wing piece rod 76 is provided below the back surface side of the left movable wing piece 54 and inside the left movable wing piece support shaft 72, and is located below the back surface side of the right movable wing piece 56.

As shown in FIG. 12 (A), which is an explanatory view showing the flow of the game balls in the variable winning device, the game balls are viewed from the left and right sides of the variable winning device 50 when the pair of movable wing pieces are opened. When 94 and the game ball 96 enter at the same time, as shown in FIG. 12 (B), the ball receiving surface 85 moderates the downflow speed of the game ball 94 at this intermediate position in the longitudinal direction and temporarily holds it. The ball receiving surface 87 moderates the flow velocity of the game ball 96 at positions near the tip and the base in the longitudinal direction,
Hold temporarily. When the left movable wing piece 84 and the right movable wing piece 86 start to close when the game ball 94 and the game ball 96 win the prize, the game ball 94 and the game ball 96 are temporarily held at positions displaced from each other. As shown in FIG. 12 (C), they enter the opening 52 while being offset from each other.

In the second embodiment, since the left movable wing piece 84 and the right movable wing piece 86 have irregularities different from each other, when the pair of movable wing pieces are opened, the left movable wing piece 84 and the right movable wing piece are movable. Even if the game ball 94 and the game ball 96 respectively enter the wing pieces 86 at the same time, the game ball 94 and the game ball 96
Are temporarily held at positions displaced from each other. Thereby, even if the left movable wing piece 84 and the right movable wing piece 86 start to close when the game ball 94 and the game ball 96 win, the opening 5
Since you can shift the timing to enter 2,
It is possible to smoothly guide the game ball 94 and the game ball 96 to the opening 52. Therefore, it is possible to prevent the occurrence of ball clogging.
