DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball tray of a pachinko machine to which pachinko balls are purchased and replenished or winning balls are supplied.

[0002]

2. Description of the Related Art FIG. 2 is a perspective view showing an example of a pachinko machine.

[0003] In FIG. 2, reference numeral 1 denotes a pachinko machine, which includes a game board 2, a front panel 3 located in front of the game board 2,
It comprises an upper ball receiving tray 4 and a lower ball receiving tray 5 attached to the front plate 3, and a launching mechanism 6 disposed inside. Since the upper ball receiving tray 4 is a ball receiving tray according to the present invention, the upper ball receiving tray 4 will be simply referred to as the ball receiving tray 4 hereinafter.
It is described.

When playing a game with the pachinko machine 1, when a pachinko ball is purchased and supplied to the ball tray 4, the pachinko ball rolls in the ball tray 4 and proceeds to the outlet 4o, and from the outlet 4o. It is supplied to the launching mechanism 6. The pachinko ball supplied to the launching mechanism 6 is
Is launched toward the game board 2. The pachinko ball hit in this manner flows into the winning opening while flowing down the front side of the gaming board 2 or an outlet provided on the lower side of the gaming board 2 without entering any winning opening (not shown). Are omitted).

As described above, when the pachinko ball hit by the hitting mechanism 6 wins, the winning ball is supplied to the ball tray 4 from the inflow port 4i. Then, when the ball tray 4 cannot receive the winning ball, the winning ball is discharged to the lower ball tray 5.

The above-mentioned ball tray 4 guides the pachinko balls one by one to the outlet 4o while rolling the pachinko balls by their own weights.
The bottom is inclined toward the outlet 4o, and the path of the pachinko balls is gradually narrowed toward the outlet 4o. Therefore, when the ball tray 4 is full of pachinko balls, the pachinko balls are put into a balling state, and a frictional force is easily generated between the pachinko balls. appear. Therefore, it is necessary to take measures for smoothly rolling the pachinko balls to the outflow port 4o without causing a ball clogging phenomenon in the ball receiving tray 4.

FIG. 3 is a plan view showing a conventional ball tray, and FIG.
3 is a cross-sectional view taken along line AA in FIG. 3, and the same or corresponding parts as in FIG.

In these figures, reference numeral 41 denotes a guiding groove provided at the bottom of the ball receiving tray 4, which has a longitudinal sectional shape formed in a concave shape with a sharp corner, and guides the pachinko ball P to the outlet 4o. .

When the guiding groove 41 is provided in the ball receiving tray 4 as described above, the pachinko ball P is moved to the guiding groove 41 as shown in FIG.
Are in point contact with both edges and are in a state of easy rolling, and are guided by the guiding groove 41 to roll to the outlet 4o. Therefore, the pachinko ball P can be smoothly rolled to the outlet 4o without causing the ball clogging phenomenon. Note that such a ball tray 4 is disclosed in, for example, Japanese Patent Application Laid-Open No. H8-182836.

[0010]

A conventional guide groove 41 is
The longitudinal cross-sectional shape is a concave shape with sharp corners. Therefore, if dust or the like accumulates in the guide groove 41, it is difficult to remove dust and the like in the corners of the corners, so that the maintenance work of the ball receiving tray 4 is troublesome. Further, dust and the like remain in the lower corners of the guide grooves 41, so that the appearance of the ball receiving tray 4 deteriorates.

The present invention has been made in order to solve the above-mentioned inconvenience, and it is an object of the present invention to provide a ball tray for a pachinko machine which can easily remove dust and the like accumulated in a guide groove and has a good appearance. is there.

[0012]

SUMMARY OF THE INVENTION The present invention relates to a ball tray of a pachinko machine provided with a guide groove for guiding a pachinko ball toward an outlet, wherein the guide groove has a U-shaped vertical cross section. is there.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical cross-sectional view of a portion of a ball tray of a pachinko machine according to an embodiment of the present invention in which a guide groove is provided, and the same or corresponding portions as in FIGS. Is omitted. FIG. 1 is a longitudinal sectional view corresponding to FIG.

In FIG. 1, reference numeral 42 denotes a guide groove provided at the bottom of the ball receiving tray 4, and has a U-shaped longitudinal section, and guides the pachinko ball P to the outlet (4o).

When the guiding groove 42 is provided in the ball receiving tray 4 as described above, the guiding groove 42 comes into point contact with the pachinko ball P at both edges as shown in FIG. Similarly, a state of easy rolling is ensured, and the rolling is smoothly guided to the outlet 4o by the guiding groove 42 without causing the ball clogging phenomenon. Then, the longitudinal sectional shape of the guiding groove 42 is
Because of the letter shape, that is, the lower corner of the guide groove 41 is rounded, dust and the like accumulated in the guide groove 42 can be easily removed. Therefore, the maintenance work of the ball tray 4 can be performed easily and easily without any trouble. Further, since all dust and the like in the guide groove 42 can be removed, the ball receiving tray 4 has a good appearance.

[0016]

As described above, according to the present invention, since the vertical cross-sectional shape of the guide groove is U-shaped, dust and the like accumulated in the guide groove can be easily removed. Therefore, the maintenance work of the ball tray can be easily and easily performed without any trouble. Further, since all dust and the like in the guide groove can be removed, the ball receiving tray has a good appearance.
