an actuating lever 37 comprising a ball stopper piece 35 that prevents balls from flowing down after a certain number of balls lined up; an actuating lever 37 that includes an inclined cam portion 36 that pushes the ball stopper piece 35 into the passage portion 24; the opening/closing lever 34 and the actuating lever 37; It consists of a solenoid 38 that operates the . The half-odd ball return means is composed of a stopper 39 that always protrudes from above at the end of the passage 24 to prevent the balls lined up in the passage 24 from flowing down, and a solenoid 40 that moves the stopper 39 away from the passage 24. The stopper 39 is integrally provided at the lower end of the plunger 41 of the solenoid 40.

The ball detecting member 27 is always urged to rotate by its own weight to the position indicated by the chain line in FIG. Then, by receiving one ball in the ball holder 26, it rotates to the solid line position in the figure, and the actuating piece 43 of the first switch 28 is pressed by the upwardly protruding protrusion 42. Activate. Reference numeral 44 is a stop rod that restricts the rotation range of the ball detection member 27. Further, the position of the ball detection member 27 is set so that a number of balls corresponding to a certain number of game balls are lined up on the exit side of the passage section 24 with one ball placed on the ball receiving section 26. .

The ball stopper piece 35 is inserted into the groove 45 of the ball detecting member 27, and has a weight 46' at its lower end, and normally descends as shown by the solid line in FIG. It is placed on the upper surface of the section 26. When the actuating lever 37 is pushed upward as shown by the chain line in the same figure by the inclined cam portion 36 of the actuating lever 37, the ball is prevented from flowing down after a certain number of balls. Further, the opening/closing lever 34 has a horizontal L-shape, and one end thereof is connected to the outlet 3.

Next, the action will be explained. In FIG. 3, the balls in the upper ball tray 2 enter the passage 24 and flow down while rotating the ball detection member 27 downward by the weight of the balls, and the first ball is stopped by the stopper 39 and stored in a continuous state. be done. At this time, the protrusion 42 of the ball detection member 27
The first switch 28 is actuated momentarily each time the ball passes, and the signal is used to detect the arrival of the ball or to store and confirm the storage status such as counting.
Then, when a number corresponding to a certain number of game balls, that is, 16 or more balls in this embodiment, are stored in the passage section 24, the balls _B1 from the 16th ball are transferred to the ball receiving section of the ball detecting member 27. 26 and while rotating it downward as shown by the solid line in Figure 3, turn the first switch 2.
8 in operation. In addition, the second switch 29
The actuating piece is pushed by the balls lined up in the passage section 24 and kept in an energized state.

In this state, when the player presses the switch button 5 on the front of the machine, the solenoid 38 is energized, and the opening/closing lever 3
4 is disengaged from the plunger 46 of the solenoid 38 and rotates as shown in FIG. 4 to open the outlet 32. At the same time, the actuating lever 37 is pushed leftward, and its inclined cam portion 36 pushes the ball stopper piece 35 upwards to stop a certain number of balls, that is, the 17th and subsequent balls. As a result, of the balls lined up in the passage section 24, only the number corresponding to a certain number of game balls, that is, 16, are discharged from the outlet 32 to the collection passage 30.
At this time, the solenoid 21 is also energized, and the stopper 23 is pulled upward to allow a certain number of game balls enclosed in the game machine main body 1 to flow into the storage passage 20 and to be ejected onto the game board surface. After a certain period of time has elapsed, the solenoid 38 is demagnetized, the opening/closing lever 34 and the operating lever 37 return to the state shown by the solid line in FIG. Save balls on 24th. Note that even if the switch button 5 is pressed when the solenoid 38 is demagnetized and the ball is flowing through the passage portion 24, that is, when the ball stops passing over the actuating piece 29' of the second switch 29, the solenoid 38 will not operate. When the balls, which are not energized and are lined up in the passage section 24, rest on the actuating piece 29', the second switch 29 is activated, thereby enabling the solenoid 38 to be energized. Therefore, the solenoid 38 is never excited when there are only half-sized game balls, and the game balls can be reliably collected into the collection path 30 by dividing into pieces corresponding to a certain number of game balls.

Further, when the number of balls stored in the passage section 24 is a certain number, that is, less than 16 balls, the ball detection member 27 rotates upward by its own weight without receiving the ball weight. The switch 28 is in an inoperative state. When the player presses the switch button 5 in this state, the solenoid 40 is energized, the stopper 39 is pulled upward, and the odd balls lined up in the passage section 24 flow into the return passage 31 and are discharged into the lower ball tray 3.

As described above, the constant ball detection device a according to the present invention
It is possible to reliably divide the balls placed in the upper ball tray in front of the machine into pieces that correspond to a certain number of game balls enclosed in the main body of the game machine and collect them all at once. Compared to the method in which the balls in the upper ball tray are collected one by one using a driving means such as a solenoid, not only the electrical load can be significantly reduced, but also the time can be significantly shortened. It also has a function that can reliably detect odd balls that are less than a certain number of game balls and return them to the player, and its practical value is truly great.
