[0008]
On the back side of the pachinko machine P, a mechanism plate 1 is attached as shown in FIG. The mechanism plate 1 includes, in order from the top in accordance with the flow of the pachinko balls, a ball tank 2 that stores the pachinko balls, a lead rod 3 that guides the pachinko balls of the ball tank 2, and an end of the lead rod 3 that is connected to the premium plate. A ball discharge device 4 that discharges balls and rental balls, and a prize ball discharge basket 5 that connects the ball discharge device 4 and a ball tray (not shown) on the front surface of the pachinko machine P are installed.
[0009]
The prize ball discharge basket 5 has a substantially vertical crank shape having a first bent portion 5a and a second bent portion 5b, and a ball outlet 6 communicating with the upper ball tray opens into the first bent portion 5a. A receptacle 7 is formed so as to surround the bottom side and the side side of the bulb outlet 6. Further, an overflow ball passage 8 is provided on the first bent portion 5a next to the receiving rod 7, and the overflow ball passage 8 is connected to the lower ball tray via the second bent portion 5b. Further, a curved basket 9 is provided at the upper end opening of the prize ball discharge basket 5 to direct the released pachinko ball to the bulb outlet 6 side.
[0010]
Inside the prize ball discharge rod 5, bells 10A and 10B are installed between the curved rod 9 and the ball outlet 6 and at the second bent portion 5b, respectively. As shown in FIG. 1, the upper bell 10A has a center on a vertical line passing through almost the end of the curved rod 9, and the discharge port 4a of the ball discharge device 4 is located on the left side of the vertical line. Accordingly, all pachinko balls released from the ball discharge device 4 collide with the left half of the bell 10A. On the other hand, the lower bell 10B is located at the upper corner of the second bent portion 5b of the prize ball discharge basket 5, and is at the point where the pachinko ball changes direction from sideways to down. Therefore, most of the pachinko balls flowing down collide with the lower right half of the bell 10B.
[0011]
First, the bell 10A will be described. A shaft-shaped bell pedestal 11 as shown in FIGS. 3 and 4 protrudes from the prize ball discharge basket 5 at the installation point of the bell 10A. The bell pedestal 11 has a plate-like pedestal side engaging means 12 projecting from the shaft end surface 11a. The pedestal side engaging means 12 includes a neck portion 12a having the same width as the shaft diameter of the bell pedestal 11, and a head portion 12c in which fixing pieces 12b and 12b are projected on both sides, and the height t of the neck portion 12a. Is set slightly smaller than the wall thickness of the bell 10A. The lower surface of the fixed piece 12b of the head 12c is rounded as shown in FIG.
[0012]
As shown in FIG. 4, the bell 10 </ b> A is obtained by processing a metal into a circular cup shape, and has a bell side engaging means 13 at the center of the bell bottom. As shown in FIG. 5 (b), the bell side engaging means 13 is continuous with a long hole 13a having the same shape as the head part 12c of the base side engaging means 12, and both sides of the long hole 13a. The side 13b is composed of substantially triangular notches 13c and 13c that are curves centered on the center O of the bell 10A. The two notches 13c and 13c are formed at point-symmetrical positions with respect to the center O of the bell 10A, and the pedestal side is formed in the space formed by the two notches 13c and 13c and the long hole 13a. The neck 12a of the engaging means 12 can be fitted. In FIG. 3, reference numeral 14 denotes a lid cover that closes the prize ball discharge basket 5, and a watermark 15 is formed on the lid cover 14 to make the sound of the bell 10 </ b> A sound outside.
[0013]
Next, a method for attaching the bell 10A will be described. First, from the state of FIGS. 5 (a) and 5 (b), as shown in FIG. 6, the elongated hole 13a of the bell side engaging means 13 of the bell 10A is fitted into the head 12c of the base side engaging means 12, and the bell 10A Is brought into contact with the shaft end surface 11 a of the base side engaging means 12. In this state, when the bell 10A is rotated approximately 45 degrees counterclockwise as shown in FIG. 7, the neck portion 12a of the base side engaging means 12 is fitted into the notches 13c and 13c. At this time, a part of the bottom of the bell 10A enters the lower surface of the fixing piece 12b of the head 12c. However, since the height t of the neck 12a is slightly smaller than the thickness of the bell 10A, the fixing piece 12b as shown in FIG. The rounded lower surface is rubbed and slightly crushed by the bell 10A, and this acts as a resistance to fix the bell 10A to the bell base 11. Further, in order to release the fixation of the bell 10A, the bell 10A may be rotated in the clockwise direction in the opposite direction to the above in FIG.
[0014]
Thus, in this state, when the pachinko ball is released from the ball emitting device 4 as shown by a two-dot chain line in FIG. 1, the pachinko ball either falls straight down or obliquely downward along the curved ridge 9. Fall. Either way, the pachinko ball collides with the left half of the bell 10A, and the bell 10A resonates. Further, when the pachinko ball collides with the left half portion of the bell 10A, a counterclockwise rotational moment acts on the bell 10A in FIG. 1 due to the collision. As described above, the bell 10A is set so as to be fixed by counterclockwise rotation in FIG. 1 and to be unlocked by clockwise rotation. Therefore, a counterclockwise rotational moment is applied by the collision of the pachinko ball. By doing so, the fixed state of the bell 10A is reliably maintained without being loosened. Therefore, even if the pachinko ball collides with the bell 10A for a long time, the fixation does not loosen.
[0015]
On the other hand, the bell 10B of the second bent portion is not shown, but has the same structure as the bell 10A except that the position of the notch 13c is completely symmetrical. Also, the pedestal 11 for the bell corresponding to the bell 10B is exactly the same as that corresponding to the bell 10A. Therefore, the bell 10B is rotated by about 45 degrees in the clockwise direction opposite to the bell 10A in FIG. It can be attached to the pedestal 11. As described above, the lower bell 10B is located at the point where the pachinko ball flowing laterally from the overflow ball passage 8 changes its direction downward, so the pachinko ball almost collides with the lower right half of the bell 10B, and the collision Thus, a clockwise rotational moment acts in FIG. Therefore, even if the pachinko ball repeatedly collides, the fixing of the bell 10B does not loosen.
[0016]
Although the present invention has been described with reference to the embodiments, it is needless to say that the present invention is not limited to the above embodiments. For example, the bell pedestal 11 may be provided on the lid cover 14 side of the prize ball discharge basket 5.
[0017]
In addition, the bell pedestal 11 and the pedestal side engaging means 12 are integrally formed with a synthetic resin when the premium sphere discharge rod 5 or the lid cover 14 is molded as a separate part and a method of retrofitting the premium sphere discharge rod 5 or the lid cover 14. However, the latter, which is integrally formed with a synthetic resin, is superior in terms of workability and cost compared to the former method, which is retrofitted.
[0018]
【The invention's effect】
The bell mounting structure of the present invention employs a fixing structure in which one side is fitted and turned to the other, so there is no trouble of tightening through the screw one by one, and there is no work loss due to the falling of the screw. Can be improved. Since the bell bottom is sandwiched between the end face of the bell base and the fixing piece, there is an effect that the bell is not loosened even when used for a long time.
[0019]
Further, if the lower surface of the fixing piece is rounded as in claim 2 , the rounded lower surface is rubbed against the bell bottom and slightly crushed, so that the collapse is a resistance for fixing the bell to the bell base. Become.
