[0003]

SUMMARY OF THE INVENTION In the above conventional configuration,
It is necessary to move a plurality of model horses along the circular path while adjusting their speeds, and the program of the drive mechanism and the controller for moving each horse is extremely complicated and the manufacturing cost is high.

In view of the above-mentioned conventional drawbacks, the present invention is a game system in which a large number of balls are used instead of using a model horse, and an arbitrary ball is extracted from the large number of balls and the extracted ball is used as a hit ball. The purpose of the present invention is to provide a ball extraction method for a game machine that has a simple structure and is extremely inexpensive to manufacture.

[0005]

To achieve the above object, according to the present invention, a circular field in plan view is provided in the center of the upper surface of a game machine body so as to movably accommodate a large number of balls having identification marks. In addition, a first fan communicating with a first air outlet formed on a side wall of the field is provided, and a second fan is provided in a center base projecting at a central portion in the field, and the center base is provided. One or more tubular goal posts are erected on the upper side, and a ball entrance and a plurality of second air outlets communicating with the goal posts are formed on the side wall of the center base at predetermined intervals in the circumferential direction. An opening is formed at one end of a partition wall that separates a communication passage that connects the ball entrance and the goal post from the inside of the center base, and a third wall is formed on the bottom wall of the communication passage. A third fan that communicates with the air outlet is provided, and a guide member that guides the ball falling from the goal post to the field is provided in the communication passage, and the ball faces the side wall of the field facing the ball inlet / outlet. A direction changing body for changing the position of the ball is projectingly provided, and a stopper is provided to prevent the ball that has entered the goal post from coming out of the upper end opening of the goal post to operate the first fan. The air is tangentially blown into the field from the first air blowing port, and the second fan is operated to blow the air into the field through the second air blowing port and the opening of the partition wall. And blow air into the field through the ball entrance and exit,
A large number of balls in the field are swirled on the air flow, and after a lapse of a certain time, the third fan is operated to blow out air from the third air outlet into the goal post and stop the operation of the second fan. By doing so, among the many balls that turn in the field, the ball that changes direction by hitting the direction changing body and enters the ball entrance is pushed up to the goal post and extracted.
After the ball is extracted, the operation of the third fan is stopped so that the ball extracted in the goal post is lowered by its own weight, passes through the guide member, and returns from the ball entrance / exit into the field.

[0006]

In the case of playing this horse racing game, after inserting a coin into the coin insertion hole, the expected first push button is pushed in the case of a win-win game, and the expected first and two in the case of a win-win game. Press the button on the clothes. Next, the game is started under the control of the control device, but if the extraction method of the present invention is adopted, the following operation is achieved. That is,
When the first fan is operated, air is blown into the field from the first air outlet, and when the second fan is operated, air is blown into the field from the second air outlet and the partition wall Air is blown into the field through the opening and the ball entrance / exit, and a large number of balls in the field are swirled randomly on the air flow. Even if a large number of swirling balls hit the direction-changing body and come close to the ball entrance / exit, the air from the second fan blowing from the ball entrance / exit into the field through the opening prevents the ball from unexpectedly entering the ball entrance / exit .

After a lapse of a predetermined time from the start of turning of the ball, the third fan is operated to blow air from the third air outlet into the goal post, and when the second fan is stopped, the ball entrance / exit is opened. Due to the negative pressure condition, among the many balls that are turning on the air flow, the ball that changed direction by hitting the direction changer is sucked into the ball entrance and exit, and the air blown toward the goal post causes the inside of the goal post. It is pushed up by and hits the stopper to be extracted.

Since the upper end opening of the goal post is blocked by the ball by the extraction, the air blown into the goal post from the third air outlet changes its direction and is blown from the ball inlet and the field toward the field, and inside each goal post. There is no risk of other balls getting in. Check the extracted ball, and if the extracted ball is as expected, the coins will be multiplied and returned. Further, after the ball is extracted, the operation of the third fan is stopped, so that the ball in the goal post descends by its own weight, passes over the guide member, and is returned from the ball entrance / exit into the field. Then, the first and second fans are operated again, and the arbitrary ball extraction / ejection is repeated in the above order. In this case, one ball can be randomly taken out of a large number of balls in the field by using air and the direction changing body, and has a drive mechanism of complicated structure and a complicated control program as in the conventional case. Since it is not necessary to use a microcomputer, the structure is simple and the manufacturing cost can be made extremely low.
