A ball detection sensor 18 for detecting the hit ball and a sliding member 16 are fixed to a support plate 28' on the back side of the mounting board 6.
The solenoid 19 is configured to move the solenoid 19 to a position above the general winning a prize opening 11b in accordance with electrical energization.

The plunger 20 of the solenoid 19 is connected to the rear end of the sliding member 16, and when the solenoid 19 is demagnetized, the sliding member 16 is biased by a coil spring 21 wound around the plunger 20, as shown by the solid line in FIG. It is forced to be located within the concave chamber 9 as shown in FIG. The upper surface of the sliding member 16 is formed in an inclined shape so as to coincide with the inclined bottom surface of the recessed chamber 9 when the sliding member 16 moves forward. Further, a protruding member 44 is formed in the recessed chamber 9 above the sliding member 16. This protruding member 44 makes it difficult for the balls received by the impellers 10a and 10b to enter the winning hole 15 of the special prize winning hole 14.

The impellers 10a and 10b have a plurality of blades 10 on their outer peripheries at intervals that allow them to receive a ball. This impeller 10a,
10b is in a first state in which it is difficult to accept a hit ball during outward rotation, and the ball is not received between the blades 10, but instead guided from one side to the bottom of the game board.

During inward rotation, the ball is held between the blades 10 as a second state in which it is easy to receive the ball, and the ball is won into the general prize winning holes 11a to 11c or the special prize winning hole 14.

Further, the impellers 10a and 10b have a supporting shaft 22.22 projecting from the center, and this supporting shaft 22.22 is connected to a guide hole 23.23 bored in the mounting board 6 and a support plate 24 at the rear of the mounting board 6. It is inserted into the drilled guide hole 25.25. Further, small diameter gears 27a and 27b are fixed to the ends of the support shafts 22 and 22, respectively.

A forward and reverse rotation motor 28 for rotating the impellers 10a and 10b is mounted on the support plate 28'. A drive gear 30 is fixed to the output shaft 29 of the forward/reverse rotation motor 28 , and a floating gear 31 having the same diameter that meshes with the drive gear 30 is mounted on a shaft 32 projecting from the support plate 24 . The small diameter gear 27a is meshed with the drive gear 30, and the idler gear 3
1 are meshed with small diameter gears 27b, respectively.

Further, an impeller moving means 32 is mounted on the back surface of the mounting board 6. This impeller moving means 32 includes a solenoid 33 attached to the support plate 24 and a link member 34a.

34b. An engagement member 37 having left and right engagement holes 36a and 36b is fixed to the plunger 35 of the solenoid 33. The link members 34a and 34b are formed by integrally connecting an arm piece 39 with a cylindrical part 38 formed at the lower end and a horizontal piece 41 with a pin 40 protruding through a cylindrical body 42. Support rod 26.
Each cylindrical body 42 is loosely inserted into 26 and is rotatably supported. The spindles 22, 22 of the impellers 10a, 10b are loosely inserted into the cylindrical portions 38.3B of the link members 34a, 34b, respectively, and are rotatably supported. In addition, the engaging member 3
The pin 40 of the link member 34a is engaged with the engagement hole 36a of No. 7, and the pin 40 of the link member 34b is engaged with the engagement hole 36b.
are respectively engaged. Link member 34a.

34b are connected to each other by a spring 43, which always urges the impellers 10a and 10b to the inner position shown by the solid line in FIG. placed in a state.

The rotation of the drive gear 30 caused by the drive of the forward/reverse rotation motor 28 gives rotation to the impeller 10a through the small diameter gear 27a, and also rotates the impeller 1 through the idle gear 31 and the small diameter gear 27b.
Rotation is applied to impeller 0b at the same speed and in the opposite direction as impeller 10a. That is, the impellers 10a and 10b are
It performs an outward rotation in the state of , or an inward rotation in the second state. In this embodiment, the rotation direction of the forward/reverse rotation motor 28 is normally set so that the impellers 10a, 10b continue to rotate outwardly. Then, when the hit ball enters the special prize winning hole 14, the rotation of the forward/reverse rotation motor 28 is reversed. Furthermore, when a ball enters the starting prize openings 4a and 4c provided on the game board 2, the solenoid 33 of the impeller moving means 32 is energized once, and when a hitting ball enters the starting prize opening 4b, the solenoid 33 is activated. It is set to be energized twice.

As a ball receiving member, in place of the impellers 10a and 10b, for example, movable pieces may be pivoted to face each other on the front surface of the mounting board, and when the rotating movable pieces stop in an upright position, they receive the hit ball and the first In this case, both movable pieces may be tilted outward to enter a second state in which the ball can be easily received. In addition, an opening/closing plate is provided in front of the through hole made in the mounting board, and the first
In the first state, the opening and closing plate may be opened forward, and in the second state, the opening and closing plate may be closed. In this case, a general prize winning hole and a special prize winning hole are formed at the back of the through hole.

Next, the operation of this embodiment will be explained as a six-impeller 10a.

When 10b is in the first state in which they are rotating outwardly relative to each other, 1
The balls that fall into the impellers 10a and 10b are only guided downward, making it difficult for the balls to enter. In this state, if the ball enters either the starting prize opening 4a or 4c, the solenoid 3
3 is excited. Therefore, the solenoid 33 sucks the plunger 35 downward and pulls down the horizontal pieces 41 of the link members 24a and 24b, so that the arm pieces 33 as shown by the chain lines in FIG.
9 is rotated outwardly against the force of the spring 43.

As a result, the impellers 10a, ], Ob move outward as shown by the chain lines in FIG. 5, expanding the receiving range of the hit ball. At the same time, the impeller 10a.

The small diameter gears 27a and 27b of 10b are the drive gears 3, respectively.
The impellers 10a and 10b are free to rotate as they are removed from the 0° floating gear 31. Therefore, at this time, the ball is hitting the impeller 1.
When the ball falls to 0a, 10b, the impellers 10a, 10b rotate outwardly or inwardly depending on the falling position of the hit ball, and when rotating inwardly, guide the hit ball to the general prize winning hole 11a to llc or the special prize winning hole 14. The impellers 10a, 10b
The time period during which the The impellers 10a and 10b return to their original positions indicated by solid lines in FIG. 5, and at the same time the small diameter gears 27a and 2
7b is the drive gear 30. They mesh with the floating gears 31 and continue to rotate outward. still.

When the hit ball enters the starting prize opening 4b, the above operation is repeated twice. In addition, the solenoid 19 of the special prize winning opening 14 during the above operation
is demagnetized. For this reason, the sliding member 16 is retracted rearward as shown by the solid line in FIG. 7, and the winning hole 15 is located within the concave chamber 9, making it difficult for the ball to win.

When the hit balls received by the impeller 10a and LOb enter the general winning holes 11a to I1'c, they are only discharged as local winning balls. On the other hand, when the ball enters the winning hole 15 of the special winning hole 14, the ball exit sensor 1
8 is detected, and based on the signal, the rotation of the forward/reverse rotation motor 28 is reversed to make it rotate inward, thereby causing the impeller 10 to rotate inward.
a and 10b are inwardly rotated in the second state in which hitting balls are likely to enter, and the solenoid 33 is energized to move the impellers 10a and 10b outward at predetermined time intervals 14; A special prize game state continues (for example, for 30 seconds).

During this operation, when a plurality of balls (for example, 6 balls) enter the general winning holes 11a to Ilc, they are detected by the ball detection switch 46, and the solenoid 19 of the special prize winning hole 14 is energized. As a result, the plunger 20 is attracted and the sliding member 16 is moved forward as shown by the chain line in FIG. Due to this movement of the sliding member 16, the winning hole 15 of the special prize winning hole 14 is positioned above the general winning hole 11b, making it very easy for balls to enter. When the ball enters the winning hole 15, the solenoid 19 is demagnetized and the sliding member 16 retreats to its original position, at the same time the above operation is repeated again. In addition, this operation is repeated a certain number of times, and a predetermined number of times (
For example, 8 times) is completed or the impellers 10a, 10
The ball hits the special prize winning slot 1 within the predetermined time when b rotates inward.
4, the reversible rotation motor 28 is reversely rotated to rotate outwardly, and the blades $10a and 10b return to the first state in which they rotate outwardly.

In addition, in this embodiment, the solenoid 19 of the special prize winning hole ill
Although the explanation has been made in relation to the number of balls won into the general winning holes 11a to 11c as a condition for energizing, the winning hole 15 may be moved to a position where balls can easily enter by energizing at regular intervals. In addition, the special prize winning hole 1 of the special prize winning hole 14
5 in advance in a position where the ball can easily enter,
When a ball is hit, the winning hole 15 may be moved to the grass position where the ball is hit.

[Effects of the Invention] As described above, according to the present invention, the special prize winning opening for giving the special prize game state is provided so as to be movable in the front and back direction.

By moving this special prize winning opening based on predetermined game conditions, it is possible to make it easier for the ball to enter, thereby attracting the interest of the players and improving the service to the players. This has the advantage of significantly increasing the interest of the game.
