Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game ball discharging device for awarding a game ball or renting a game ball.

[0002]

2. Description of the Related Art In a pachinko gaming machine, a storage tank for storing pachinko balls is attached to the upper rear surface of the gaming board,
This storage tank is connected to a pachinko ball (game ball) discharging device via a guideway or the like. Then, the pachinko balls in the storage tank are sent out to a supply plate or the like on the front of the game board by a pachinko ball discharging device as prize balls or rental balls.

By the way, conventional game ball discharging devices include a cam (stopper) type, a sprocket type, and a lead screw type. Of these, the sprocket type uses a sprocket to discharge the game balls, and a plurality of recesses are provided at equal intervals on the outer periphery thereof so that one game ball can be placed. Then, in response to a discharge command signal, the game balls that the sprocket falls along the guide passage are sequentially taken into the concave portion, and the game balls are discharged while rotating. When a predetermined number of game balls are discharged, the game ball to be discharged next is stopped by the discharge stop command signal in a state of being taken into the recess. Whether or not a predetermined number of game balls are discharged is counted and determined based on the detection output of a sensor attached to the guide passage. In this case, in the conventional game ball discharging device, the sensor is often attached to a position where the game ball taken into the sprocket recess can be detected.

[0004]

However, when the sensor is attached to such a position, the game ball to be detected hits the sprocket and bounces off, or the game ball has already fallen into the game ball already taken into the sprocket recess. There was a problem that a miscount occurs when the ball hits and bounces. On the other hand, in order to avoid such a problem, if a sensor is attached below the sprocket, there will be a time lag until the game ball released from the sprocket is detected by the sensor, and the control timing for stopping the sprocket becomes complicated. Will be lost. Therefore, an object of the present invention is to provide a game ball discharging device that does not cause a miscount and does not require complicated control of the timing of stopping the sprocket.

[0005]

In order to achieve the above object, the present invention provides a notch on the outer periphery of which a game ball can be placed, faces the guide passage, and flows down along the guide passage. A notch disk that rotates while holding the coming game ball in the notch and holding it with the side surface of the guide passage, and the guide passage provided so that the game ball can be detected In a game ball ejecting device for ejecting a predetermined number of game balls, which comprises a ball detecting means, downward from within the radius of the game ball from the lowermost end of the game ball when the cutout disk is in a holding state immediately before releasing the game ball. In addition, the ball detection means is arranged by arranging a position for detecting a game ball.

[0006]

According to the above invention, the position where the ball detecting means detects the game ball is arranged below the lowermost end of the game ball within the radius of the game ball in the holding state immediately before the cutout disc releases the game ball. Therefore, the game ball to be detected is not affected by the notch of the notch disk, and is not affected by the game ball to be detected next. Also, the game ball to be detected is detected by the ball detection means almost at the same time as it leaves the notched disk.
