In this example, the ball dispensing device 5 is of a double type so that a prize ball and a lending ball can each be dispensed. The ball tank 1 introduces balls from the ball supply holes at the end into the lower ball alignment rail device 2 in a state of multiple rows and two rows.
[0009]
In this example, the ball tank 1 is supported by a set plate 6 in a cantilever structure, and can be fixed to a receiving frame (not shown) by clamp mechanisms 7 and 7 in use. The ball alignment rail device 2 is supported by a holding mechanism 8 that hangs down from the ball tank 1 at the left end in the drawing, and is supported by inserting the right end in the drawing into the ball deceleration guide passage 4. Is composed of an upstream alignment portion 9 and a downstream alignment portion 17.
[0010]
2 to 3 are a plan view and a vertical sectional view of the upstream side alignment portion 9 of the ball alignment rail device 2 provided with the payout ball shortage detecting device 3 of the present invention, and FIG. 4 is a sectional view taken along the line AA in FIG. It is. The upstream side alignment portion 9 is formed symmetrically via the central partition 10 in correspondence with the double ball delivery device 5, and the payout ball shortage detection device 3 is also provided in a duplex manner on each side. Only one side will be described below.
[0011]
The upstream side alignment portion 9 is formed in a width that can accommodate two rows of mainstream and secondary flow ball rows on the ball entry side, and a guide side wall 11 of the secondary flow ball row is formed on the outside. ing. Reference numeral 15 denotes a groove-shaped guide means for holding the lowermost mainstream ball row in a single line, and the bottom surface 16 of the mainstream ball row is inclined downward toward the downstream as shown in FIG. The bottom surface 12 is inclined so as to be higher than the mainstream ball row on the downstream side, and is inclined lower toward the mainstream ball row side so that the secondary flow ball row is higher than the mainstream ball row as shown in FIG. . For this reason, the balls on the bottom surface 12 of the secondary flow ball row naturally flow into the main flow side as they move to the downstream side and become one row. And flows into the ball deceleration guide passage 4.
