[0005]

However, in recent pachinko machines, since the game content is lost in the mold and the freshness is lost, the size of the variable display device is increased to make the game content more interesting. However, the size of the window was limited due to the positional relationship between the ball tank and the tank rail, and it was difficult to mount a large-sized variable display device.
In addition, although it is thought that the window portion can be easily enlarged by moving the tank rail upward, there is a problem in that moving the tank rail upward causes ball clogging at the ball outlet of the ball tank. .

Further, in the conventional ball tank, a ball outlet is provided at the lower end of the bottom wall inclined, and the pachinko balls supplied to the ball tank go to the ball outlet at a stretch due to the inclination of the bottom wall. As a result, the ball pressure of the pachinko ball in the ball tank concentrates on the ball outlet, and a ball biting phenomenon occurs at the ball outlet so that the ball is clogged. There was a problem that it could not flow out of the exit.

[0007] Therefore, the present invention can effectively relieve the ball pressure applied to the ball outlet so as to allow the pachinko balls in the ball tank to flow out smoothly without causing ball clogging, and furthermore, the window of the mechanism plate. The aim is to provide a ball tank for a pachinko machine that can secure a large amount of space.

[0008]

In order to achieve the above object, a ball tank for a pachinko machine according to the present invention has a box-shaped storage portion having an open upper surface and a ball outlet formed on one longitudinal side wall. And a passage portion for aligning the pachinko balls on the bottom wall and leading to the ball outlet, forming a ball outlet on the upstream side, and providing a ball guiding portion communicating with the ball outlet on the bottom of the bottom wall. Was.

The ball guiding portion is provided with a ball-aligning passage for aligning and flowing down the pachinko balls in a line, and the width of the ball-aligning passage is preferably wider than 12 mm. Preferably, the number is less than two.

[0010] It is preferable that the inclination of the bottom wall toward the ball outlet is different from the inclination toward the ball outlet, so that the ball pressure of the ball tank is divided into two.

It is preferable that the inclination of the passage portion and the inclination angle of the ball guiding portion are different from each other, and that the inclination of the ball guiding portion is larger than the inclination of the passage portion.

Further, below the window 7, a prize ball discharging processor 13 for discharging the prize balls collected in the prize ball collecting section 12 one by one.
Is provided.

Thus, the ball tank 8 is shown in FIGS.
As shown in the figure, a rear wall 14 in contact with the mechanism plate 5, a front wall 15 facing the rear wall 14, a left wall 16 and a right wall 1
The storage portion 19 of the pachinko sphere formed in a substantially rectangular box shape whose top surface is open is formed by the bottom wall 7 and the bottom wall 18. A passage portion 20 for guiding and aligning the pachinko balls is formed on the bottom wall 18 of the storage portion 19, and a ball outlet 21 communicating with the passage portion 20 is opened on the right side wall 16. The bottom wall 1
Numeral 8 is gently inclined downward toward the ball outlet 21, and the passage portion 20 is formed in a funnel shape by a swelling portion 22 in which the front and rear walls 14, 15 are asymmetrically swelled inward on the downstream side. are doing. In addition, the passage portion 20 is formed by an alignment wall 23 formed so as to become higher toward the center toward the lower side.
Ball aligning passage 20 in which pachinko balls are arranged in a row and flow down
a, 20b, so that pachinko balls flow down in two rows. A vertically rectangular ball outlet 24 is provided on the upstream side of the bottom wall 18.
A ball guiding portion 25 is provided integrally on the lower surface of the bottom wall 18 in communication with the bottom wall 18. The ball guiding portion 25 is formed to be inclined downward toward the right side wall 17, and has a slightly larger inclination than the ball passage 20. Further, a bulging portion 22 provided on the bottom wall 18 and an aligning wall 26 formed so as to become higher as it goes downward toward the center, a ball aligning passage in which pachinko balls align and flow down. 25a, 25b, and the pachinko balls flow down in two rows.

The height of the ends of the ball alignment passages 25a and 25b is a height at which two pachinko balls do not pass, and the width is about 1
The pachinko balls are arranged in a zigzag state at 4 mm, and the pachinko balls are supplied without interruption even if the ball payout device 10 pays out at high speed. In the present embodiment, the ball passages 20a, 20b, 25a, and 25b of the passage portion 20 and the ball guiding portion 25 are formed by the bulging portion 22 provided on the bottom wall 18. However, FIGS. As shown in FIG. 9, the ball alignment passages 25a, 25 of the ball guiding portion 25
b may be formed by bulging the front and rear walls 14, 15 of the ball tank 8.

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, it flows out of the ball outlet 21 to the guiding gutter 9, and also flows out of the ball outlet 24 to the guiding gutter 9 via the ball guiding part 25. At this time, the ball pressure of the pachinko ball in the ball tank 8 is distributed to the ball outlet 21 provided on the right side wall 17 and the ball outlet 24 provided on the bottom wall 18, and the ball outlet 21,
No ball pressure is applied to the ball outlet port 24. As a result, the pachinko balls flowing out of the ball outlet 21 and the ball outlet port 24 do not cling to each other, and the ball does not bite and clog the ball. And it can be reliably led to the ball payout device 10 through the guide gutter 9. Note that FIG.
As shown in (1), the position of the ball outlet 24 may be changed or the number may be increased depending on the size of the ball tank 8, the amount of the ball, or the like.

When the ball dispensing device 10 is operated and the pachinko balls are discharged to the discharge gutter 11, the pachinko balls in the ball tank 8 are changed from the state shown in FIG. The pachinko ball flows out preferentially through the guiding portion 25 to the guiding gutter 9, and the pachinko ball flows out slowly from the ball outlet 21. As described above, since the ball pressure of the pachinko balls in the ball tank 8 is dispersed by providing the ball outlet 21 and the ball outlet 24, the distance between the ball guiding part 25 and the bottom wall 18 is reduced to the vicinity of the ball outlet 24. In this case, the height can be set so that almost one pachinko ball passes, 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.

FIG. 11 shows an embodiment in which the inclination direction of the bottom wall 18 is different, and the ball outlet 2 provided on the left side wall 16 side.
By making the inclination toward 4 different from the inclination toward ball exit 21,
The bottom wall 18 is formed in a mountain shape so as to divide the ball volume of the ball tank 8 into two. As a result, the ball pressure applied to the ball outlet 21 and the ball pressure applied to the ball outlet 24 are divided into two, and the ball pressure applied to the ball outlet 21 is further reduced, and the pachinko balls in the ball tank 8 are smoothly transferred to the guiding gutter 9. Can be supplied.

[0019]

As apparent from the above description, in the present invention, the ball outlet is provided on the side wall of the storage portion of the ball tank and the ball outlet is provided on the bottom wall of the storage portion. The ball pressure of the pachinko ball in the tank is dispersed, so that the ball pressure can not be applied to the ball outlet at a stretch, and the situation where pachinko balls cling to each other and ball biting occurs is reliably eliminated and the pachinko ball smoothly Can be drained. In addition, since the tank rail is eliminated, a large window portion can be formed to allow a central accessory such as a board box or a variable display device to face.
