Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ball tank for a pachinko machine that accommodates prize balls.

[Prior Art] As is well known, a normal pachinko machine has a ball tank located above the back surface of the machine, and the prize balls stored in the tank are transferred to a prize ball release device using an inclined guide gutter having two ball passages. A certain number of prize balls are released each time a winning ball is generated.

By the way, in recent pachinko machines, the prize balls in the ball tank are guided to two prize ball release devices by an inclined guide gutter with three ball passages, and the number of prize balls released depends on the type of winning ball. There is a tendency to increase the interest of games by making them different.

[Problems to be solved by the invention] For this reason, a ball tank with a droplet facing the two ball passages of the inclined guide gutter and a ball tank with a droplet facing the three ball passages of the inclined guide gutter are proposed. There was the inconvenience of having to prepare two types.

The present invention was devised in view of the above circumstances, and its purpose is to provide a ball tank for a pachinko machine that can be used in any of the above-mentioned pachinko machines by means of simple additions. .

[Means for solving the problems] The structure of the present invention to achieve the above purpose is as follows:
This will be explained using FIGS. 1 to 3 corresponding to the embodiment.

The present invention consists of a ball tank main body 1 having a bottom portion 5 provided with a droplet 6 sized to face three ball passages 4a to 4c of an inclined guide gutter 3 that guides prize balls to a prize ball release device.
and an auxiliary bottom plate 2 which is detachably attached to the inside of the spherical tank body 1. By attaching the auxiliary bottom plate 2, the opening 6 of the tank body 1 is connected to the two grooves of the inclined guide gutter 3. The structure is such that the size can be changed to face the ball passages 4a and 4b.

[Function] By attaching the auxiliary bottom plate 2 to the ball tank main body 1, the drop opening 6 thereof is sized to face the two ball passages 4a, 4b of the inclined guide gutter 3. Also,
By removing the auxiliary bottom plate 2 from the ball tank body 1, the opening 6 thereof is sized to face the three ball passages 4a to 4c of the inclined guide gutter 3. This allows the ball tank to be used for two different types of pachinko machines.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. In the figure, 1 is the ball tank main body, 2 is an auxiliary bottom plate that is detachably attached to the ball tank main body 1, 3 is arranged below the ball tank main body 1, and three ball passages 4 are provided.
It is an inclined guide gutter having a to 4c. The ball tank body 1 is formed into a box shape with an open top surface, and a droplet 6 is formed at the bottom 5 for dropping the prize ball into the inclined guide gutter 3. The opening width L of the droplet 6 in the front and back direction is the same as the two ball passages 4a of the inclined guide gutter 3.
It is formed in a size opposite to ~4c.

The auxiliary bottom plate 2 is formed into a substantially L-shaped cross section by an upright part 8 that is in contact with the inner surface of the front wall 7 of the spherical tank body 1 and a bottom plate part 9 that is received on the upper surface of the bottom part 5. It is removably attached by fitting the shaped bent portion 10 into the upper edge of the front wall 7 of the spherical tank body 1. When attached to the ball tank body 1, the tip of the bottom plate part 9 closes a part of the droplet 6, and the opening width L of the droplet 6 in the front and back direction is connected to the two ball passages 4a of the inclined guide gutter 3. , 4b are changed in size to face each other. In this example,
A locking protrusion 11 is formed on the bent portion 10 of the auxiliary bottom plate 2, and a groove 12 into which the locking protrusion 11 fits is formed on the front surface of the front wall 7 of the spherical tank body 1, so that the auxiliary bottom plate 2 does not fall off unnecessarily. That's what I do. 13 is a game board of the pachinko machine, and 14 is a mechanism plate to which the ball tank body 1 is attached.

The present invention has the above-mentioned configuration, and when the auxiliary bottom plate 2 is not attached, the prize balls accommodated in the ball tank body 1 pass through the three ball paths from the opening 6 of the bottom part 5 to the inclined guide gutter 3. 4a to 4c,
By installing the auxiliary bottom plate 2, the inclined guide gutter 3
The ball is guided to two ball paths 4a and 4b. Therefore, in the case of a normal pachinko machine equipped with an inclined guide gutter having two ball passages, it is sufficient to attach the auxiliary bottom plate 2 of the ball tank body 1 and use the slanted guide gutter with three ball passages. In the case of a pachinko machine equipped with an inclined guide gutter, it is sufficient to remove the auxiliary bottom plate 2 from the ball tank body 1 and use it, making it possible to use it for two types of pachinko machines.

[Effects of the invention] As described above, according to the invention, one type of ball tank can be used for two types of pachinko machines, and the economic effects thereof are great.
