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. For example, JP-A-64-6
In 2182, a sprocket is arranged on the side of a notch formed on one side of the ball discharge path, and a sprocket claw is rotated by a ball passing through the ball discharge path and falling, and a stopper is operated by a solenoid to operate the sprocket A ball-cutting device is disclosed that locks on a pawl and prevents rotation of a sprocket.

[0004]

As described above, the sprocket type is provided with the stopper for preventing the rotation of the sprocket. By the way, since the game ball discharging device discharges a predetermined number of prize balls or rental balls, it is important to operate the stopper accurately. Therefore, an object of the present invention is to provide a sprocket-type game ball discharging device that can reliably discharge a predetermined number of game balls.

[0005]

In order to achieve the above object, the invention according to the present application places a notch provided on the outer periphery on a guide passage and a game ball flowing down along the guide passage is placed on the notch. Sprocket that sends the game ball to the guide passage while rotating, a gear that is coaxially attached to the sprocket and rotates integrally with the sprocket, and its tip is the tooth surface of each tooth of the gear. A game ball discharging device, comprising: a stopper that stops rotation of the sprocket by blocking rotation of the gear by abutting against a tooth surface in the direction in which the gear rotates, wherein the tip portion of the stopper is the stopper. The toothed surface of each tooth of the gear with which the tip of the stopper abuts is easily contacted by the tip of the stopper. And it is configured as inclined at sea urchin predetermined angle.

[0006]

According to the above invention, the sprocket is mounted on the notch of the game ball flowing down the guide passage and is rotated while the game ball is fed out. At that time, the gear wheel coaxially attached to the sprocket is rotating together with the sprocket. When a predetermined number of game balls are discharged, the tip of the stopper abuts the tooth surface of each tooth of the gear provided in the direction of rotation to prevent rotation of the gear, and at the same time the sprocket rotates. Is stopped. In that case, since the curved portion provided at the tip end portion of the stopper avoids the preceding tooth facing the tooth surface of the tooth to be abutted, the stopper abuts the tooth surface of the tooth to be abutted. Since each tooth surface in the rotation direction of the gear is inclined at a predetermined angle so that the tip of the stopper can easily come into contact, the tip of the stopper comes into contact with each tooth surface without hitting the tip of the tooth. It is like this.

With such a configuration, a predetermined number of discharge balls are provided in the sensor 9
When counted based on the detection signal of 0, the solenoid 102 is demagnetized and the restoring force of the restoring spring 103 causes the tip 101b of the stopper 101 not to hit the tooth 44b, and to the tooth 44d having the bearing surface 44c. It abuts against the bearing surface 44c without hitting it. As a result, the rotation of the sprocket 41 is stopped and a predetermined number of game balls are accurately discharged.
The rotation preventing gear 44 and the sprocket 41,
42 are axially mounted so that the 16 notches 45 and 16 teeth of the rotation blocking gear 44 coincide with each other on their respective central axes. Therefore, only by demagnetizing the stopper solenoid 102, the position where the stopper 101 engages with the rotation blocking gear 44 is always in the normal position.

There is. Also, the reference numeral 90A indicates the optical axis of the discharge sensor 90. The discharge sensor 9
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 axis 90A is set at a position (hereinafter referred to as a detection position) that is within a radius of the game ball, for example, about 3 mm lower than the lowest end of the game ball at the maximum position, and the discharge sensor 90 is attached. ing.
