DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine for adjusting the number of stored balls by detachably mounting a partition plate inside a prize ball tank.

[0002]

In a pachinko parlor, when a prize ball tank of a pachinko machine becomes empty, a ball replenishing device automatically replenishes game balls. In this case, by keeping the number of game balls replenished at one time from the ball replenishing device constant, it is possible to manage the number of balls in each pachinko machine from the number of ball replenishments. Since such management of the number of balls to be played differs in each pachinko parlor, the prize ball tank has a configuration in which the number of stored balls can be adjusted. An example is disclosed in Japanese Utility Model Laid-Open No. 58-68080.

In this apparatus, a plurality of vertical grooves are formed on the inner surfaces of a front wall and a rear wall of a prize ball tank, and a partition plate is removably fitted in the groove. By changing or removing the position, the number of stored balls can be easily adjusted.

[0004] In the case of a pachinko machine equipped with a prize ball tank having the above-described configuration, usually, the partition plate is shipped in a state where it is attached to the prize ball tank in advance. Therefore, when the pachinko machine is sometimes handled upside down during shipping, there is a problem that the partition plate that is merely fitted in the groove portion immediately falls out of the groove portion.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a structure in which a partition plate is detachably mounted inside a winning ball tank, and the partition plate is handled even if it is handled upside down. To provide a pachinko machine that can prevent the machine from coming off.

[0006]

In order to achieve the above object, a pachinko machine according to claim 1 of the present invention has a partition plate removably mounted inside a winning ball tank. The plate is fixed to a mounting portion provided in the winning ball tank via an engaging means.

[0007] According to the above configuration, the partition plate attached to the attachment portion is fixed to the attachment portion by the engaging means. Therefore, even when the pachinko machine is turned upside down, the partition plate does not come off from the mounting portion.

In this case, if a plurality of mounting portions are provided (claim 2), the number of stored balls in the prize ball tank can be variously changed by changing the position where the partition plate is mounted. Further, the engaging means may be configured by providing a convex portion on the partition plate and providing a fitting concave portion on the mounting portion, or by providing a fitting concave portion on the partition plate and providing a convex portion on the mounting portion. With this configuration (claim 3), the partition plate can be fixed to the mounting portion with a relatively simple configuration.
