And a delivery mechanism 40 for delivering the game balls guided respectively to the game ball outlets 17 and 18,
It comprises a rotating mechanism 70 (see also FIG. 9) for rotating the delivery mechanism 40, and a stop mechanism 100 for stopping the rotation of the delivery mechanism 40. Then, the discharge sensors 90 and 91 are attached so as to detect the game balls sent by the sending mechanism 40.

In the delivery mechanism 40, a pair of sprockets 41, 42 as notch disks provided with a plurality of (eight in this embodiment) notches 45 formed so that game balls can be delivered at equal intervals. (Hereinafter, the sprocket 41 may be a representative example.)
And a driven gear 43 as a first gear that applies rotational power to these sprockets between the sprockets 41 and 42, and a second gear that blocks rotation of the sprockets 41, 42. And a rotation-preventing gear 44 as a shaft. The shaft attachment means that the sprocket 41, the sprocket 42, the driven gear 43, and the rotation blocking gear 44 are fixed to the shaft 46, respectively. The rotating mechanism 70 includes a motor 70A as a drive source, a driving gear 72 fixed to a rotation shaft 71 of the motor 70A, and the driving gear 7

As a result, the game balls in the guide passages 30 and 31 are fitted into the notches 45 of the sprocket and sent out one by one. Then, the discharge number is counted based on the detection signals of the discharge sensors 90 and 91, and when a predetermined number is discharged, the stopper solenoid 102 is demagnetized based on a discharge stop signal from the ball discharge control device 5, By the restoring force of the return spring 103, the stopper 1
01 is engaged with the rotation preventing gear 44, and at the same time, the motor 70A is stopped. Thus, in the game ball discharging device 6 according to the present invention, the sprockets 41, 4
Since the rotating mechanism 70 is provided for 2, the game ball can be sent out at a constant speed, and the uncertain factor of utilizing the natural fall of the game ball as in the conventional example can be eliminated. In addition, the stop mechanism 1 for the sprockets 41, 42
Since 00 is separately provided, there is no need to perform complicated control of the stop timing as in the conventional example. That is, it is only necessary to demagnetize the stopper solenoid 102 when a predetermined number of game balls are discharged.

Reference numeral 01 indicates a stopper, respectively. 104 is a base stopper for keeping the stroke of the stopper 101 constant. The sprocket 41 in FIG. 8 shows a position where the sprocket stands still (hereinafter referred to as a normal position) in order to maintain the normal stop position of the game ball. The dotted line position of the stopper 101 shows a state where the stopper is attracted by the solenoid 102, and the solid line position shows a state where the stopper 101 is returned by the return spring 103.

The tip of the stopper 101 is provided with a curved portion 101a for escaping the tooth 44b immediately before the tooth groove 44a with which the stopper 101 and the rotation preventing gear 44 engage. On the other hand, a tooth surface 44c (hereinafter referred to as a bearing surface) in the rotation direction of each tooth of the rotation blocking gear 44 is provided with an inclination of about 5 degrees with respect to the central axis of the gear 44, as shown in the drawing. With such a configuration, when the predetermined number of discharged balls are counted based on the detection signal of the sensor 90, the solenoid 102 is demagnetized and the return spring 10 is demagnetized.
By the restoring force of 3, the tip flat surface portion 10 of the stopper 101 is
The rotation of the sprocket 41 is stopped by the contact of 1b with the bearing surface 44c of the gear 44. The rotation blocking gear 44 and the sprockets 41, 42 are arranged on the central axes of
Each of the notches 45 and the 16 teeth of the rotation preventing gear 44 are axially attached so as to coincide with each other. Therefore, only by demagnetizing the stopper solenoid 102, the stopper 101
The position that engages with the rotation blocking gear 44 is always the normal position.

Next, an example of the structure of the motor 70A of the rotating mechanism 70 will be described. A pulse motor is used as the motor 70A, for example, a V having a multi-phase stator winding.

Next, with reference to FIG. 9, an arrangement relationship between the delivery mechanism 40 and the motor 70A will be described. FIG. 9 is a perspective view of the game ball discharging device 6 from the right oblique direction.
As described above, the driven gear 43 has two sprockets 4
It is pivotally mounted between the first and the second parts. Therefore, this sending mechanism 40
A motor 70A is disposed below the motor 70A, and the driven gear 4 is provided via a driving gear 72 of the motor 70A and the transmission gear 73.
The rotational force of the motor 70A is transmitted to the motor 3.
As described above, in the game ball discharging device 6 according to this embodiment, the motor 70A is arranged below the feeding mechanism 40 and so as to be substantially housed between the two sprockets. Therefore, the game ball discharging device 6 itself is designed compactly. Is able to. This means that the space where the back surface of the game board can be effectively used is widened, and the degree of freedom in designing the game board is increased.

It is desirable that the discharge sensor 90 be attached so that the optical axis 90A of 0 is located within the radius of the ball (the diameter of the game ball is 11 mm) from the lowermost end of the game ball at the maximum position. In this embodiment, the optical axis 90A is mounted at a position about 3 mm below the lowermost end of the game ball B. When detecting the game ball, it is desirable to detect the game ball after discharge from the game ball before being sent to the sprocket. In this case, if the sensor is attached to the regular position, it may be erroneously detected when the game ball hits the sprocket and bounces off, and if it is installed below the maximum position, more than the predetermined number of game balls are discharged. In some cases, In such a case, it becomes difficult to control the stop timing of the sprocket. Therefore, in this embodiment, the optical sensor 90A is set and the discharge sensor 90 is attached to a position lower than the lowermost end of the game ball at the maximum position within a radius of the game ball, for example, about 3 mm.
