That is, as shown in FIGS. 7 to 10, a plurality of rows, for example, five rows of the partition passages 71, 72, which are partitioned by a passage width L of one pachinko ball P from the lower end of the pachinko ball supply hopper (not shown). A partition wall 76, 77, 78, 79 forming 73, 74, 75 is provided integrally with a passage bottom plate 80 to form a ball alignment passage 81. Above the ball alignment portion of the ball alignment passage 81, A plurality of large-diameter eccentric disks 82 for guiding the pachinko balls P existing in the lateral direction to the partition passages 71 to 75 and a plurality of small-diameter eccentric rollers 83 for preventing the pachinko balls P from overlapping are formed on the same shaft. An external ball aligning mechanism 85 attached to the external ball aligning mechanism 84.
[0004]
In this conventional external ball aligning mechanism 85, at least the entire portion from the pachinko ball replenishing hopper to the ball aligning section is partitioned into one pachinko ball P, and the partitioning member and the regulating member on the passage bottom plate 80 described above. Due to the formation of the partition walls 76 to 79, when the two pachinko balls P, P ride on the corresponding upper surfaces 77a, 78a of the partition walls 77, 78 adjacent to each other as shown in FIGS. Due to the gravity of the pachinko balls P, P, there is a problem that a ball jam phenomenon (a so-called bridging phenomenon) occurs and a good flow of the pachinko balls P is hindered.
[0005]
Further, since the above-described partition walls 76 to 79 exist at least on the upstream side (the left side in FIG. 9) from the disposition positions of the above-described eccentric disks 82 and the eccentric rollers 83, the positions indicated by α in FIG. When the pachinko balls P are prevented from overlapping, the pachinko balls P are moved by the eccentric roller 83. However, the behavior of the pachinko balls P is limited to only the movement in the front-rear direction, and the jamming (or bridge) phenomenon is eliminated. However, there is a problem that the time required for this is long.
[0006]
In addition, as shown in FIG. 10, the partition walls 76, 79 which are distributed to the outside by the ball alignment mechanism 85 for the pachinko balls P flowing down the partition passages 71, 75 on both sides in the plural rows of the partition passages 71 to 75. Although the pachinko ball P receives a force directed outward from the upper pachinko ball P, the movement of the pachinko ball P is deteriorated by the existence of the partition wall, so that the flowing state of the pachinko ball P flowing down in a plurality of rows varies, and all rows have a variation. There is a problem that it is not possible to ensure a uniform flowing state over the entire area.
[0007]

A large number of pachinko balls P... Which are randomly inserted into and stored in the pachinko ball supply hopper 30 receive a prize ball signal when a player wins a prize by a pachinko game machine, and the drive motor rotates, thereby causing all pachinko balls P to be common to all rows. The ball reaches the ball alignment section 6 via the first ball downflow passage 7 and the second ball downflow passage 9 common to all rows. Here, the ball is sorted by the action of the ball alignment roller 8 in the left and right lateral direction so as to correspond to each row. After the overlap is prevented, the ball reaches the ball discharge passage 12 divided by the partition wall 10, and is further discharged from the ball discharge 4 through the ball discharge passage 12 by the rotation of the ball counting cam 11. The predetermined number is discharged to the prize ball exit portion on the front side of the machine.
[0025]
By the way, the deformed sorting disks 16, 17 and the deformed rollers 18, 19, which are alternately arranged on the shaft 15 rotating in the opposite direction to the downflow direction of the pachinko balls, form the flat shape of the ball aligning section 6 with the deformed rollers 18, 19 for preventing overlap. When the pachinko balls P in the second ball downflow passage 9 are first distributed in the left and right and lateral directions, and then the pachinko balls P are prevented from overlapping, the plurality of pachinko balls P are allowed to behave in the front-rear direction and the left-right direction. This has the effect of preventing the occurrence of the conventional clogging phenomenon (so-called bridge phenomenon).

In addition, by expanding the behavior range of the pachinko balls P in this way, it is possible to significantly shorten the clogging elimination time and the overlap elimination time, and furthermore, the above-described sorting disks 16 and 17 and the irregular shaped roller Since the pachinko balls 18 and 19 are driven in the direction opposite to the downward direction of the pachinko balls, there is an effect that the performance of loosening the pachinko balls P can be improved.
[0027]
In addition, since the first and second ball flow passages 7, 9 upstream of the ball alignment section 6 are formed flat and have no conventional partitioning member and regulating member, the behavior of the pachinko ball P is improved. An unnecessary resistance is not given to the ball, and an effect of ensuring an even flow-down state in all the rows of the ball down passages and all the rows of the ball discharge passages 12.
[0028]
Furthermore, there is an effect that the structure of the ball flow passages 7, 9 upstream of the ball alignment section 6 can be simplified.
In addition, since the ball alignment mechanism 2 having the above-described configuration is unitized and the unitized ball alignment mechanism 2 is integrated into the discharge device main body 1, the conventional long rail and the conventional external ball alignment mechanism are integrated. The mechanism can be omitted, and as a result, the back surface of the pachinko machine can be simplified and the design flexibility can be improved, and the prize ball pachinko ball P can be quickly discharged without flowing down a long rail. Exit 4 In other words, since the distance between the ball supply port 3 and the ball discharge port 4 of the housing 5 immediately below the hopper 30 is extremely short, there is an effect that the high-speed discharge of the prize ball pachinko balls P can be achieved.
