DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a ball payout device according to the present invention. In the figure, reference numeral 1 denotes a ball inlet which communicates with a ball storage tank or the like provided on the back side of the pachinko gaming machine and is connected so that the pachinko balls p flow down in an aligned manner, and 2 denotes a ball inlet below the inlet. It is a gentle inclined gutter formed in a downward inclined shape. At the lower end of the gently inclined gutter, a vertical falling gutter 4 is extended via a bent portion 3 that sharply curves downward. Note that these pachinko balls p
Gutter 2, refraction part 3, and falling gutter 4 for flowing down
Has a substantially square tubular cross section.

Reference numeral 6 denotes a claw piece rotatably supported in a vertical plane by a support shaft 7 outside the downfall gutter 4, an interlocking piece 8 rotatably supported in a vertical plane by a support shaft 9, Reference numeral 9 denotes a solenoid, and an operating body 10 fixed to a spindle of the solenoid.
The protrusions 11 are engaged with the engaging portions 12, 12 formed on the interlocking piece 8.
The protrusion 13 formed on the interlocking piece 8 is loosely fitted between the claw pieces 6.
Is loosely fitted between the engaging portions 14 formed on the rear surface of the base,
When the solenoid 9 is actuated, the interlocking piece 8 and the claw piece 6 rotate repeatedly, and the tip 15 of the claw piece 6 moves from the vertically elongated hole 16 formed in the side wall 4a of the downflow gutter 4 along the longitudinal direction to the downflow gutter 4. By moving in and out, the flow of the pachinko ball p can be stopped.

As shown in FIG. 2, reference numeral 17 denotes an optical ball counting sensor comprising a light projecting device 17a and a light receiving device 17b. Reference numeral 18 denotes a U-shaped mounting frame for supporting the sensor. Are arranged so that their optical axes 19 intersect at a position slightly downstream of the pachinko ball p supported by the claw pieces 6 by the mounting frame and at a position deviated from the center line of the downfall gutter 4. The pachinko ball immediately after the stop by the claw piece 6 is released is arranged so as to detect the pachinko ball by blocking the optical axis 19.

As shown in FIG. 3, the elongated hole 16 is formed in a slit shape having a width w of 5 mm at the center of one side wall 4a of the downfall gutter 4. The inner diameter of the gutter 4 is such that the distance y between the inner surfaces of the side walls 4c and 4d perpendicular to the inner surface of the side wall 4a where the elongated hole is formed and the inner surface of the opposing side wall 4b is longer than the distance x. Is set to (Ie, x <y). Since the diameter of the pachinko ball p is generally 10.5 to 11 mm, the distance x is 11.5 m so that a required gap is formed.
m and the distance y are set to 12 mm. FIG. 2
As shown in (2), the pachinko ball p intervenes in the vertical hole 4 to reduce the lateral vibration (vibration in the x direction) of the pachinko ball at the site where the vertical hole 16 is opened.

In the embodiment shown in FIG. 1, as shown in FIG. 4, a cross section of the downfall gutter 4 below the portion where the vertically long hole 16 is formed is formed. Therefore, both inner diameters are equally set to 12 mm. In other words, the distance x is 1 below the lower edge of the vertically long hole 16.
The diameter is expanded to 2 mm. (That is, x ′ = 12 in FIG.
mm).

For this reason, even if the pachinko ball p intervenes in the elongated hole 16, the pachinko ball p can flow straight down at the lower edge 16a of the elongated hole without receiving an impact. For this reason, the pachinko ball p has a vertically long hole 1
It is possible to avoid the possibility that double detection is performed by the ball counting sensor 17 without hitting the lower edge 16a of the sensor 6 and bouncing.

In this ball dispensing device, when the solenoid 9 is excited by a command from the ball dispensing control device, the tip 15 of the claw piece 6 sinks from the vertically long hole 16 as shown in FIG. Is stopped, the pachinko ball p is paid out by its own weight, and when the ball counting sensor 17 detects a predetermined number of pachinko balls, a command is issued again from the ball payout control device and the claw piece 6 protrudes. As a result, the payout of the pachinko ball p is stopped.

On the other hand, FIG. 6 shows another embodiment of the present invention.
Is formed so as to be inclined inward and downward, so that the pachinko ball that has intervened in the elongated hole smoothly exits from the elongated hole. This also eliminates the possibility of double detection due to bouncing of the pachinko ball p. In this embodiment, the side wall 4 opposed to the lower edge 16a of the vertically long hole 16 is
The inner diameter of 12 mm is ensured by expanding b outside below this portion 4b '.

In another embodiment of the present invention shown in FIG. 7, the elongated hole 16 extends sufficiently below the detection position of the pachinko ball p by the ball counting sensor 17. The extension must be at least a hemisphere of the pachinko sphere p more than the detection position of the pachinko sphere p.
Thereby, even if a bounce occurs, a trouble such as double detection by the ball counting sensor does not occur.

The embodiment shown in FIG. 8 is similar to the embodiment shown in FIG.
The ridges 5 and 5 having a width of 3 mm and a height of 0.2 mm along the longitudinal direction are formed at the center of the inner surface of each of c and 4d. The ridges 5 and 5 are formed not only on the inner surface of the downfall gutter 4 but also on the inner surfaces of the inclined gutter 2 and the bent portion 3. By forming the ridges 5 and 5 in contact with the pachinko sphere p on the inner surface of the flow path in this way, even if the dirt of the pachinko sphere p adheres to the ridges 5 and 5 and accumulates, the dirt can escape to both sides. Therefore, it is possible to prevent the inside diameter from being narrowed due to dirt, thereby preventing the flow of pachinko balls from being deteriorated.

In this embodiment, an optical sensor has been described as the ball counting sensor. However, sensors of other detection types such as an electromagnetic sensor and a capacitance sensor can be used.
