Description

[Detailed description of the invention] This invention relates to a prize ball tank that is installed at the upper part of the back side of a pachinko machine and stores game balls to be ejected as prizes, and the position of the partition member provided inside is changed. This makes it possible to change the number of balls stored.

In a pachinko parlor, the number of times balls are replenished into a prize ball tank in each pachinko machine is limited to a certain value, and when the limit is exceeded, the pachinko machine is stopped.

In such pachinko parlors, if the number of balls stored in the prize ball tank of each pachinko machine can be adjusted, the number of balls hit can be adjusted, and the ball output rate can be easily managed.

For this reason, prize ball tanks that can adjust the number of stored balls have been developed, such as the Jikkosho 406194.
Publication No. 40-24195, Publication No. 1987-24195, Publication No. 1987-24195
There are publications such as No. 116689.

However, in order to adjust the number of balls stored in these prize ball tanks, the screws must be loosened and tightened, making adjustment work cumbersome, especially in pachinko parlors with many pachinko machines. The machine's prize ball tank must be adjusted, which is extremely time-consuming.

Furthermore, since the pachinko machine generates significant vibrations during play, the vibrations cause the screws to loosen and the partition plate to move, resulting in the disadvantage that the preset number of stored balls may be incorrect.

Furthermore, since the partition plate is a thin plate, it may break or bend due to severe impact when replenishing pachinko balls, and it will no longer function as a partition.

Therefore, in this proposal, vertical grooves are formed facing each other on the inner surfaces of the front and rear walls of the prize ball tank, and the retaining part of the partition member is made removable within these grooves, thereby increasing the number of balls stored. To provide a prize ball tank which can be easily adjusted and whose partition member never moves even when subjected to vibrations during a game.

The present invention will be explained below based on drawings of embodiments.

The prize ball tank 1 is a horizontally elongated box with an open top, and as shown in Fig. 1, it is placed at the upper part of the back side of the pachinko machine 2. An outlet 3 communicates with the ball outlet gutter 4, and game balls to be discharged as prizes are stored inside.

The front wall 5 of the prize ball tank 1, that is, the side wall 5 facing the back of the game board 6, and the inner surface of the rear wall 7 facing the front wall 5 are provided with vertical grooves 8, 8 facing each other. do.

In order to form the groove portion 8, a protruding strip 9 may be provided on the inner surface of each side wall, and the center portion of the protruding strip 9 may be depressed in the vertical direction.
Alternatively, each of the side walls 5, 7 may be formed with a narrow thin section in the vertical direction, and the thin section may be used as a groove.

Note that it is desirable to provide a plurality of grooves 8 so that the number of stored balls can be adjusted stepwise in units of 50 or 100 balls.

The partition member 10 divides the inside of the prize ball tank 1 into a ball outlet side portion A.
The lower part of the partition surface 11 facing the ball outlet 3 is sloped downward toward the ball outlet ``]3, and the side portions of the partition surface 11 are horizontally inclined. It has a protruding vertically elongated engaging portion 12.12.

This retaining portion 12.12 is molded so that it can be fitted into the groove portions 8, 8 of the prize ball tank 1 from above.

Therefore, when the partition member 10 is lowered after the lower end of the retaining portion 12.12 faces the upper opening end of the grooves 8, 8, it is possible to fit the partition member 10 within the gap between the opposing grooves 8, 8. The interior of the prize ball tank 1 can be divided by the width intervals of the opposing grooves.

In addition, when changing the number of stored balls, that is, when moving the partition member 10, the partition member 10 is removed from the grooves 8, 8 by raising it, and then moved to another appropriate groove 8, 8.
Just fit it into 8.

In addition, if an indication of the number of stored balls (for example, 100.150) corresponding to each groove part 8, 8 is written, the partition member 1
This is useful when moving 0.

Further, the partition member 10 is provided with a ball shortage detector for detecting a shortage of balls in the prize ball tank 1.

The embodiment of the ball shortage detector shown in FIG.
A detecting piece 13 faces into the prize ball tank 1, and an operating piece at the rear end 13 faces a detecting switch 14, which is pivotally mounted on the partition member 10 so as to be able to swing freely.

When the prize ball tank 1 is filled with game balls, the receiving piece 13a of the detection piece 13 is in a downward state as shown by the solid line in FIG. 4 due to the weight of the balls, and the detection switch 14 is turned OFF. .

Then, the ball fired by the player wins a prize, and the prize ball discharge device 15 installed at the downstream end of the ball outlet trough 4 operates, and the game ball in the ball outlet trough 4 is placed in a saucer (not shown) on the front of the pachinko machine. When the game balls are discharged as prizes, the amount of game balls in the prize ball tank 1 gradually decreases.

When the prize ball discharge is repeated and the game balls in the prize ball tank 1 become insufficient, the receiving piece 13a of the detection piece 13 rises due to the force of the weight 16 or the spring, as shown by the chain line in FIG. , the operating piece 13b descends and turns on the detection switch 14.
Make it.

When the detection switch 14 is turned on, the ball lifting device 17 of the electrically connected pachinko machine 1 operates to supply balls.

When the prize ball tank 1 is filled with balls, the detection switch 14 is turned off as described above, and the operation of the ball lifting device 17 is stopped.

Note that the detection switch 14 is provided inside the partition member 10,
The actuation piece of the detection switch may be made to protrude upward from a hole formed on the upper surface of the partition member, and may be made to face the lower side of the upper surface of the detection piece 13.

As explained above, according to the present invention, the number of balls stored in the prize ball tank can be adjusted extremely easily and reliably by simply fitting the engaging portion of the partition member into the groove of the prize ball tank from above.

Therefore, even in a pachinko parlor that has a large number of pachinko machines installed, it is possible to change the number of balls stored in all the pachinko machines in the store in a short period of time, making it possible to adjust the number of balls that are hit and, by extension, the ball output rate. becomes easier.

In addition, the partition member is positioned by the engagement between the engaging part and the groove, so it will never move or bend even if it is subjected to strong vibrations or a strong impact when replenishing pachinko balls. No errors occur.

Furthermore, the partition member is equipped with a ball shortage detector, so no matter what position the partition member is placed in, it will immediately detect when there is a shortage of balls in the tank, and promptly replenish balls or issue a stop command. be able to.
