It consists of. The ball guiding portion 20 is formed so as to be inclined downward toward the right side wall 17, and furthermore, asymmetrically bulges inward so as to gradually squeeze a part of the front and rear side walls 14, 15 on the downstream side. The ball-aligning passage 22a, in which the pachinko balls are aligned in one row and flow down by the alignment wall 21 formed so as to become higher as it goes downward.
22b, and the pachinko balls flow down in two rows. The ball alignment passages 22a and 22b are formed with a margin so that pachinko balls can easily flow down and do not clog the balls, and have a width of about 14 mm.

The bottom wall 18 of the storage portion 19 has a substantially flat surface, and bosses 23, 23 projecting from the lower surface are formed with boss holes 24, 23.
It is laid detachably by fitting it to 24 and attaching it with screws. Further, as shown in FIG. 5, the bottom wall 18 is provided so as to be gently downwardly inclined toward the left side wall 16 of the ball tank 8 opposite to the inclination of the ball guiding portion 20. At the downstream end of the bottom wall 18, a rectangular ball outlet 25 a having a front-rear width of the ball tank 8 is opened. Further, the ball alignment passages 22a and 22b are located on the upstream side of the ball outlet 25a.
A ball outlet 25b having a length that allows about two to three pachinko balls to fall is opened. 26
Is a ball leveling member provided on the lower surface of the upstream opening edge of the ball outlet 25b. The ball leveling member 26 may be a fixed type or a movable type. Further, as shown in FIG. 8, the ball tank 8 may be configured such that curved walls 27, 27 are integrally provided on the lower surface of the bottom wall 18 to form the ball alignment passages 22a, 22b. Furthermore, the ball tank 8 may be formed by vertically dividing the storage portion 19 and the ball guiding portion 20.

The ball tank 8 constructed as described above is fixed to the mechanism plate 5 by a suitable means such as a screw and the like, as shown in FIG. 4 and FIG. The pachinko balls to be stored are stored in the storage unit 19. And, the pachinko balls stored in the storage unit 19 are:
Due to the inclination of the bottom wall 18, the water flows out from the ball outlets 25 a and 25 b to the ball guiding unit 20. At this time, the ball pressure of the pachinko ball flowing down the ball tank 8 is adjusted to the ball outlet 2 provided on the bottom wall 18.
5a, 25b, and the ball outlets 25a, 25 at a stretch.
b is not subjected to ball pressure, and as a result, the ball outlet 25
The pachinko balls flowing out of the ball tanks a and 25b do not cling to each other due to clinching of the balls and clogging of the balls does not occur. Can be led to the pachinko ball dispensing device 10.

When the pachinko ball dispensing device 10 is operated to discharge the pachinko balls to the discharge gutter 11, the ball tank 8
The pachinko sphere flows out of the state shown in FIG. 7A from the sphere outlet 25b preferentially to the sphere alignment passages 22a and 22b of the sphere guiding part 20 as shown in FIG. 7B. At this time, even if the ball is likely to be clogged near the ball outlet 25b, the pachinko ball moves freely as shown by the chain line in FIG. The pachinko balls that are about to flow out of the outlet 25a break the balance and flow smoothly without clogging. And
As shown in FIG. 7C, when the number of pachinko balls upstream from the ball outlet 25b decreases, the pachinko balls gradually flow out of the ball outlet 25a to the ball guiding unit 20. As described above, since the ball pressure acting on the ball outlet is weakened by providing a plurality of ball outlets, the distance between the ball guiding portion 20 and the bottom wall 18 is set at a high level where two pachinko balls do not pass through the ball outlet 25a. By the way, the ball outlet 25b can be narrowed to a height at which three pachinko balls do not pass, and the window 7 can be enlarged accordingly. For this reason, the game contents of the pachinko machine become more sophisticated, and the variable display device 6 and the circuit board for controlling the game contents become larger, so that even if the base box 4 for accommodating the circuit boards becomes larger, it can sufficiently cope with the situation.

9 and 10, the ball outlet 25b is located above the ball alignment passage 22a of the ball guiding portion 20, and has a width of approximately 1.5 to less than 2 pachinko balls. This embodiment is preferably used when the pachinko balls in the ball alignment passage 22a frequently flow by the dispensing of the pachinko ball dispensing device 10, and disperses the ball pressure of the pachinko balls in the ball tank 8,
Pachinko balls are surely supplied to the ball alignment passage 22a without interruption without causing ball clogging.

FIGS. 11 to 13 show an embodiment in which the number of sphere outlets is increased. The sphere outlet 2 is located upstream of the ball alignment passages 22a and 22b and closer to the front and rear walls 14 and 15.
5c and 25d are provided. Reference numerals 28, 28 denote guide walls provided on the lower surface of the bottom wall 18, and the ball aligning passages 22 so that the pachinko balls flowing out of the ball outlets 25a do not obstruct the pachinko balls falling from the ball outlets 25c, 25d.
a, 22b. In addition, ball tank 8
The position of the ball outlet may be changed or the number may be increased depending on the size of the ball, the amount of the ball, or the like.

FIG. 14 and FIG.
This shows an embodiment in which ribs 29a and 29b are provided on the opening edges of 5a and 25b. As shown in FIG. 14, a flat triangular rib 29a is provided on the upstream opening edge of the ball outlet 25a, leaving a width that allows one pachinko ball to pass on the left and right, and the upstream opening edge of the ball outlet 25b. Is provided with a planar triangular rib 29b which is full of openings. This restricts the flow of the pachinko balls in contact with the bottom wall 18 on the upstream side of the ball outlets 25a and 25b, as shown by the arrow in FIG. 14, and the ball pressure of the pachinko balls flowing out of the upstream side of the ball outlets 25a and 25b. And the ball outlets 25a, 25
It is possible to prevent clogging of the portion b. Further, it is possible to adjust the ball pressure by adjusting the height and the arrangement of the ribs 29a and 29b, and it is also possible to adjust which ball outlet is preferentially drawn out.

FIG. 16 shows the ball outlet 25b of the ball tank 8.
In addition, a guide gutter 30 for guiding the pachinko ball drawn out from the ball outlet 25b in the downward direction of the ball guiding unit 20 is provided. Thereby, the pachinko ball flowing out of the ball outlet 25b is
Since the ball pressure is not applied vertically to the ball guiding unit 20 and the ball is guided in the flowing direction of the ball guiding unit 20, the ball can smoothly flow down without clogging. 31 is a ball alignment passage 2
The partition walls 2a and 22b are provided so as to correspond to the ball alignment passages 22a and 22b without riding on the alignment wall 21.

[0025]

As is apparent from the above description, in the present invention, the ball tank is composed of a storage section and a ball guiding section, and a plurality of ball outlets are provided on the bottom wall of the storage section. , The ball pressure of the pachinko ball in the ball tank is dispersed, so that the ball pressure is not applied to the ball outlet at a stretch,
It is possible to reliably eliminate the situation in which the pachinko balls cling to each other at the ball outlet and cause the ball to bite, so that the pachinko balls can flow out smoothly, and since the tank rail can be eliminated, a board box, a variable display device, etc. The window for receiving the central character can be made large.

Further, by providing the ball outlet with a guide gutter for guiding the pachinko ball to be drawn out from the ball outlet in the flow-down direction of the ball guiding portion, the flow of the ball becomes smoother.
