おそれがあった。In the ball dispensing device disclosed in Japanese Utility Model Laid-Open Publication No. 63-32581, a pachinko ball is formed by gradually increasing the lead angle of a lead screw toward the advancing direction. It is intended that the detection error of the sensor due to overlapping and falling is prevented, and the number of payouts is accurately detected. However, in the ball dispensing device disclosed in this publication, a sensor is provided in the middle of the dispensing gutter, and the sensor detects a falling pachinko ball, so that a predetermined number of pachinko balls are detected by the sensor. After that, even if a stop command is issued to the pulse motor, the pulse motor further rotates the lead screw by inertia, so that there is a possibility that the pachinko ball may be unnecessarily paid out. In particular, in order to allow a large number of pachinko balls to be dispensed in a short time, a pachinko ball may be excessively dispensed due to such inertia when a ball moving gutter is formed in two rows on both sides of one lead screw. .

The ball counting sensor has the light projecting device 10 and the light receiving device 11 mounted on a U-shaped mounting frame 9 fixed near the lower end of the case 4. Each can be mounted face-to-face. The optical axis 12 is provided outside the lead screw 1 so as to pass over both the ball moving gutters 5a and 5b, and at the moment when the pachinko ball 3 is released from the screw groove 1a of the lead screw 1, the light is released. By blocking the shaft 12, the pachinko balls 3 are detected and counted as electric signals. Note that 13
Is a bearing formed horizontally between the lower ends 7a and 7b of the case 4. The small shaft 14 formed at the tip of the lead screw 1 is supported by the bearing to stabilize the support of the lead screw 1. Let me.

出し得る。The rotation and stop of the pulse motor 2 are controlled by a ball dispensing control circuit (not shown). By rotating the lead screw 1, the pachinko balls in both the ball moving gutters 5a and 5b flow down while being restrained by the screw grooves 1a. Are discharged from the lower ends 7a and 7b to the prize ball payout gutter. The pachinko ball passing through both ball moving gutters 5a and 5b cuts off the optical axis 12 so that an electric signal obtained from the light receiver 11 is input to the ball payout control circuit, and the rotation of the pulse motor 2 is controlled. , A predetermined number of pachinko balls can be discharged to a prize ball payout gutter.

解消される。A ball counting sensor 8 composed of a light projector 10 and a light receiver 11 is connected to an optical axis 12 of the ball moving troughs 5a, 5a.
By providing the sensor so as to straddle over b, a single ball counting sensor can detect pachinko balls flowing down both ball moving gutters, and there is an advantage that manufacturing costs are reduced as compared with providing a plurality of sensors. The thread groove 1 of the lead screw 1
Since the ball counting sensor 8 is provided so that the pachinko ball at the moment when the restraint from the position a is released interrupts the optical axis 12, the pachinko ball that alternately flows down the two ball moving gutters 5a and 5b overlaps with each other to generate light. In addition to preventing the shaft 12 from being interrupted, the detection error is prevented, and the possibility that the pachinko ball is unnecessarily paid out due to the inertia rotation of the pulse motor due to the detection delay is also eliminated.

払い出し得る効果がある。As described above, the ball dispensing device for a pachinko game machine according to the present invention has two rows of ball moving gutters formed on both sides of a lead screw rotated by a pulse motor, and includes a light projector and a light receiver. The ball counting sensor is provided so that its optical axis passes over both ball moving gutters, and can detect pachinko balls of both ball moving gutters at the moment when the restraint from the screw groove of the lead screw is released. As a result, the pachinko balls can be dispensed at a sufficiently high speed by the two rows of ball moving gutters, and there is a risk of causing a detection error due to the overlap of the pachinko balls, and the pachinko balls are additionally unnecessary due to the inertial rotation of the pulse motor due to the detection delay. This eliminates the possibility of being paid out, and has the effect of always and accurately paying out pachinko balls.
