Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vertical ball cage that supplies a ball to a ball dispensing device in a gaming machine that uses a ball as a game medium.
[0002]
[Prior art]
FIG. 3 shows the back side of the pachinko machine disclosed in Japanese Patent Application Laid-Open No. 10-323437. A ball received from the tank 11 is supplied to the ball dispensing device 12 via the vertical ball cage 17, and the balls of the ball dispensing device 12 are supplied. The ball is supplied to the upper plate device 13 provided on the front side of the pachinko machine by the payout operation.
[0003]
[Problems to be solved by the invention]
However, since the above-mentioned conventional example has a structure in which the meandering ball passage 18 formed inside the vertical bulb 17 causes the ball to flow while meandering left and right, the horizontal width of the vertical bulb 17 increases to the left and right. In game machines such as pachinko machines and slot machines whose size is determined, the ball ball presses the installation space of the control device mounted on the back side of the game machine. In addition, since the meandering sphere passage 18 has a structure for guiding the spheres in a line, there is a problem that the amount of stored spheres within a predetermined dimension in the vertical direction is small.
[0004]
Therefore, the present invention provides a vertical bulb that can increase the amount of stored balls with a small width.
[0005]
[Means for Solving the Problems]
The vertical ball cage includes a cylindrical vertical case, a center rod provided in the vertical case and extending in the vertical direction, and a spiral blade fixed to the outside of the center rod. Is fixed to the vertical case, and the spiral blade is fixed to the outside of the center rod like a screw to form a spiral slope extending in the vertical direction inside the vertical case. It can be guided to swivel around an elongating central bar . Therefore, even if the horizontal width of the vertical bulb is reduced, the sphere is stored in a meandering manner in the front, rear, left and right along the spiral slope, so that the amount of bulb stored in the vertical bulb can be increased. Also, in the present invention, if the spiral slope is formed so as to carry the spheres in a double row, the amount of spheres stored in the vertical sphere can be dramatically increased.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show an embodiment, and FIG. 1 shows the vertical bulb 1 cut in the vertical direction, and FIG. 2 shows the upper portion of the vertical bulb 1 cut in the horizontal direction.
[0007]
In FIG. 1, the same tank 11, ball dispensing device 12, upper plate device 13, etc. can be used as in the conventional example. The vertical ball cage 1 for guiding the ball P from the tank 11 to the ball dispensing device 12 has a vertically extending center rod 3 fixed inside a cylindrical vertical case 2 whose top and bottom are closed, and outside the center rod 3. Since the spiral blade 4 is fixedly provided like a screw, a spiral slope 5 centering on the center rod 3 is formed in the vertical case 2 in the vertical direction.
[0008]
As shown also in FIG. 2, the upper part of the vertical case 2 is provided with a ball intake 6 for introducing the ball P supplied from the tank 11 into the spiral slope 5, and the ball discharge port 15 of the tank 11 is provided at the ball intake 6. It is inserted inward from the outside of the vertical case 2 and is continuous so that the spheres P smoothly flow in a line in a plan view at the upper end of the spiral blade 4. The lower part of the vertical case 2 is provided with a ball discharge port 7 for leading the ball P from the spiral slope 5 to the ball dispensing device 12. The sphere P is formed so as to be gradually narrowed as it goes to and is narrowed so as to form a passage that can pass through one sphere P so that the sphere P flows smoothly through the sphere inlet 16 of the sphere dispenser 12. . The vertical distance between the upper spiral blade 4 and the lower spiral blade 4 is a dimension in which two or more spheres P flow from top to bottom in a double row arranged vertically. As shown in FIG. 2, the gap 8 between the spiral blade 4 and the vertical case 2 is smaller than the diameter of one sphere P.
[0009]
According to the structure of the present embodiment, the spiral slope 5 formed inside the vertical case 2 guides the spheres P supplied from the tank 11 in the direction of the ball payout device 12 in a double row in a natural flow manner. In this way, since the spiral slope 5 guides the sphere P in a double row so as to turn around the center extending in the vertical direction, even if the horizontal width of the vertical bulb 1, that is, the horizontal width of the vertical case 2 is formed small, Since P is configured to draw meanders back and forth and right and left along the spiral slope 5, the amount of stored spheres in the vertical sphere 1 is inevitably increased.
[0010]
Although the spiral blade 4 is fixed to the center rod 3 in the embodiment, the spiral blade 4 can be similarly applied even if it is fixed to the vertical case 2.
