Abstract

PROBLEM TO BE SOLVED: To shoot a ball toward a target. SOLUTION: A control part 14 supplies arrival power to a bal shooting mechanism 21 so as to permit a ball to arrive at one of arrival detectors 8 to 11 by manually operating an adjustment operation part 20. Then the ball shot from the ball shooting mechanism 21 enters a prize-winning device 5, 6 or an outlet 7 after being detected by one of the arrival detectors 8 to 11 on a game board 1. Then a position detecting means 15 detects a ball position with a signal from the arrival detector 8 to 11 and a prize-winning rate detecting means 17 detects a prize-winning rate at every unit time, which rate is obtained by dividing the number of prize-winning balls in a start prize-winning device 5 by the total number of the balls which arrive at the arrival detectors 8 to 11 per unit time. A history calculating means 16 calculates a history 30 which decides the relationship between the number of the balls by arrival detectors 8 to 11 and the prize-winning rate, and an adjusting means 18 extracts the arrival detectors 8 to 11 with the largest number of arrival balls including the prize-winning rate which is equal to or greater than a judgment value through the use of the history 30. Then electric power to be supplied to the ball shooting mechanism 21 is controlled to shoot the balls which are shot after an adjustment operation at the extracted position.

る。Then, in the adjustment process, when the winning rate is equal to or higher than the determination value, the position identification information having the largest number of arrivals is extracted and stored from the history including the winning rate determined to be equal to or higher than the determination value.
The stored position identification information is set as the target position, and the power to the ball launching mechanism 21 is changed to the reaching power corresponding to the set target position so that the sphere thereafter can reach the target position. In this case, when the control unit 14 determines a plurality of winning rates equal to or higher than the determination value, the higher winning rate is extracted from the plurality of winning rates, so that the control unit 14 can appropriately determine the winning rate. If there are a plurality of winning rates equal to or higher than the judgment value and they have the same value, these history 30
Since the position identification information having the largest number of arrivals is extracted from, the control unit 14 appropriately determines the winning rate. On the other hand, if all of the winning rates are less than the determination value, the adjustment processing extracts the position identification information having the largest number of arrivals as the target position from the history 30 including the best winning rate, or
Instead of extracting the target position based on the history, the target position is sequentially changed from left to right, for example.

履歴３３が（４；５；９０；７／９９）となっている。The history records 31; 32; 33 will be described with reference to FIG. FIG. 2 shows a case where the target position is changed from left to right, that is, the first target position is the arrival detector 8 around the link nail 4, and the next target position is the arrival detector 9 around the top frame. Yes, history 3 when the next target position is the arrival detector 10 around the top nail 3
1-33 are illustrated. For example, as shown in FIG. 2, in the history records 31 to 33, the unit time is set to one minute, and the number of balls emitted from the ball emission mechanism 21 within the initial unit time is 99.
Of these 99, 96 balls pass through the arrival detector 8 around the link nail 4, and one of 99 balls other than the above reaches the arrival detector around the top frame. When 9 balls pass through 9 and the remaining 2 balls out of 99 balls pass through the arrival detector 10 around the sky nail 3, the number of shots becomes 99 (the number of shots = 96 + 1 + 2).
= 99). When 5 balls out of 99 win the starting winning apparatus, the winning rate is 5/99. Therefore, the history 31 in the first unit time is (96; 1; 2; 5/9
9), indicating that they are concentrated around the continuous nail 4, which is the initial target position. In this way, the history 32 when the target position is around the top frame in the next unit time becomes (3; 94; 2; 4/99), and the target position is around the ceiling nail 3 in the next unit time. When it becomes, the history 33 is (4; 5; 90; 7/99).

The determination means 14 determines that the adjustment value is equal to or greater than the determination value, and the adjustment means 18 inputs the position identification information corresponding to the arrival detector 10 around the top nail 3 from the position detection means 15 and stores the information. This stored position identification information is the target position for the subsequent adjustment control. In this case, the target position is not changed before and after the determination of the winning rate, and it can be considered that the adjustment unit 18 does not substantially perform the adjustment control because the target position is around the nail 3.

6 is a case where the target position is changed from left to right, that is, from the area around the continuous nail 4 to the area around the ceiling nail 3 through the area around the top frame. In comparison with FIG. 2, FIG. The winning rate of the history 35 in 7 is 99/99, and the winning rate of the history 36 in the next unit time is 4/99, which is different from FIG. 2, and the same case as in FIG. The target position is unit nails 3 per unit time from around the nail 4
As a result of determining the winning rate after changing to the surroundings, the adjusting unit 18 performs the adjustment control so as to return the target position from around the top nail 3 to around the top frame. Specifically, when the target position is around the top frame, the winning rate of the history 35 is 7 /
The control unit determines that the winning rate is equal to or higher than the determination value, and the adjustment unit 18 corresponds to the arrival detector 9 around the top frame from the position detection unit 15 when the determination unit determines that the winning rate is equal to or higher than the determination value. The position identification information to be input is input and stored. On the other hand, the adjusting means calculates the difference between the arrival power corresponding to the arrival detector 10 around the top nail 3 and the stored arrival power corresponding to the arrival detector 9 around the top frame, and the control unit based on the difference. The power supplied from 14 to the ball firing mechanism 21 is adjusted.
In this case, the arrival position of the sphere fired after the above state is located around the top nail 3 rather than around the top frame. It is necessary to weaken the firing force of the mechanism 21. Therefore, the adjusting unit 18 controls the electric power supplied from the control unit 14 to the ball firing mechanism 21 so as to be weak.

5; 36, when the target position is changed from right to left, that is, from the vicinity of the nail 3 to the surrounding nail 4 via the periphery of the top frame in order, the target position is changed to the nail 3 per unit time. As a result of determining the winning rate after changing from around to the continuous nail 4 through the surrounding of the top frame, the adjusting means 18 performs adjustment control so as to return the target position from around the continuous nail 4 to around the top frame. Specifically, when the target position is around the top frame, the winning rate of the history 35 is 7/99, and the control unit 14 determines that this winning rate is equal to or higher than the determination value.
The adjustment unit 18 inputs the position identification information corresponding to the arrival detector 9 around the top frame from the position detection unit 15 and stores the information when the determination value is equal to or more than the determination value. On the other hand, the adjusting means 1
Reference numeral 8 calculates the difference between the arrival power corresponding to the arrival detector 8 around the continuous nail 4 and the arrival power corresponding to the stored arrival detector around the top frame, and the control unit 14 emits a ball based on the difference. The power supplied to the mechanism 21 is adjusted. In this case,
Since the arriving position of the sphere fired after the above state is located around the link nail 4 rather than around the top frame, the urging force by the sphere firing mechanism 21 can be used to make a sphere that is subsequently ejected reach around the top frame. Need to be strong. Therefore, the control unit 1
