Description

[Detailed description of the invention] This invention has a pair of opening/closing pieces that can stand up in parallel and freely tilt in an inverted eight shape on the front of the mounting plate, and the ball that enters between the opening/closing pieces that are upright will be sent to the rear end of the ball guide plate. In a ball receiving device that tilts an opening/closing piece by lowering the rear end and flipping up the front end by the weight of the ball, an opening operating lever having a permanent magnet at an appropriate location located on the back of the mounting plate and an electromagnet are opposed to each other. The opening actuator is provided with an opening actuating device which rotates the opening actuating lever by energizing the electromagnet to repel the permanent magnet, thereby lowering the rear end of the ball guide plate and tilting the opening/closing piece. This invention relates to a ball receptacle for pachinko machines.

Conventionally, this kind of well-known ball receiving device has little change, especially when the opening and closing pieces are in a tilted state, and if a ball enters between the opening and closing pieces, it returns to the upright state. When the ball receiving device is used alone, the game becomes extremely monotonous as the player simply repeats standing up and tilting, which lacks the interest of playing pachinko.

The present invention allows the ball guide plate to be moved downward to maintain the opening/closing piece in a tilted state as long as the electromagnet continues to be energized.This invention is rich in variety, has a high probability of winning, and is highly appealing to players. To provide a ball receptacle for a pachinko machine equipped with an opening device capable of improving service and significantly increasing the interest of a pachinko game.

The illustrated embodiment will be explained below.
In the figure, 1 is a mounting plate that is attached to the surface of the game board, and a pair of opening/closing pieces 3, 3 are provided on both sides of the front side of the ball entrance 2 opened on this
is fixed by shafts 4, 4 below the center, and the opening/closing piece 3
, 3 can be moved between a parallel standing position shown by a solid line in FIG. 1 and an inverted eight-shaped tilting position shown by a chain line in the figure.

A chutker 5 is fixed to the mounting plate 1 so as to cover both sides and the front side below the shafts 4, 4 of the opening/closing piece 3.3, and the lower bottom of the chutker 5 matches the lower side of the ball inlet 2.

Reference numeral 6 denotes a guide box which covers the rear part of the ball inlet 2 and is fixed to the back surface of the mounting plate 1, and forms an outflow lower on one side wall of the guide box. A horizontal shaft 8 is provided, and a seesaw-operating ball guide plate 9 whose front end is slightly heavy is pivoted to this horizontal shaft 8.

The ball guide plate 9 has its front end facing forward from the ball inlet 2, and when the opening/closing pieces 3, 3 are upright, the front end is inserted below the shafts 4, 4 and stands up as shown by the solid line in FIG. , or flip up the front end as shown by the chain line in the same figure to cause the opening/closing pieces 3, 3 to tilt.

10 is a stopper for the ball guide plate 9.

In addition, the ball guide plate 9 whose front end is flipped up has an opening/closing piece 3 at the front end,
It is engaged with and supported on 3 to maintain its position.

The ball receiving device having the above-mentioned structure is well known, and its operation will be explained next.When the opening/closing pieces 3, 3 are erected as shown by the solid lines in FIG. When you enter between 3,
This flows from the upper part of the ball inlet 2 to the rear end on the ball guide plate 9, and the weight of the ball pushes down the rear end and at the same time flips up the front end, causing tilting of the opening/closing pieces 3, 3, and the outflow volume from the lower part to the outside. leak.

When the hit ball B□ enters between the opening and closing pieces 3 and 3 while the opening and closing pieces 3 and 3 are tilted in this way, this hits the opening and closing piece 3.
, 3 fall to the bottom of the chutka 5 while standing up, and flow out from the lower part of the ball inlet 2.

At the same time, the ball guiding plate 9 loses its support from the opening/closing pieces 3, 3, lowers its front end, intervenes below the shafts 4, 4, and repeatedly performs the action of maintaining its upright position.

Therefore, as shown in FIGS. 3 to 6, the present invention is directed to a portion of the horizontal shaft 8 that protrudes outward from the other side wall of the guide box 6, which is opposite to one side wall where the outflow lower is provided. , protrusion 1
1 and a permanent magnet 12 is rotatably supported, and its projecting piece 11 is thrust into the interior through a notch opening 14 formed on the other side wall of the guide box 6 to open the ball guide plate 9. Position it so that it can contact the rear end from above.

Reference numeral 15 denotes an electromagnet fixed to the side wall of the guide box 6 facing the permanent magnet 12. In the non-energized state, the permanent magnet 12 is attracted and the opening actuating lever 13 is held in the rotating position shown in FIG. It has a polarity that, when excited, causes the permanent magnet 12 to repel and urges and rotates the opening lever 13 in the direction of the arrow.

In addition, in the present invention, when the electromagnet 15 is de-energized, the front end of the opening actuating lever 13 is made heavier than the shaft so that the operation of the ball guide plate 9 is not hindered by contact with the protruding piece 11. In this case, there is no need to attract and hold the permanent magnet 12.

Further, the biasing force due to the repulsion of the permanent magnet is set to such an extent that it is more or less overcome by the weight of the ball.

The ball receiving device of the present invention having the above-mentioned configuration includes an appropriate switch means and an electromagnet 15 provided to be turned on by a ball passing through a specific winning hole of a game board or a winning ball flow down channel, for example. They are electrically connected and used by setting the energization state to continue for a certain period of time via a timer by turning on these switch means.

Therefore, when the opening/closing pieces 3, 3 are in the closed state, when the electromagnet 15 is energized, it is excited and generates a polarity that repels the permanent magnet 12, causing the opening lever 13 to be rotated downward as shown in FIG. It will move.

Therefore, the ball guiding plate 9 is moved downward by the protruding piece 11 as shown by the chain line in FIG. 2, thereby tilting the opening/closing pieces 3, 3.

Then, while the electromagnet 15 is energized, the opening actuation lever 13
is rotated downward by the repulsive action of the permanent magnet 12,
The protruding piece 11 continues to move the ball guide plate 9 downward to maintain the opening/closing pieces 3, 3 in a tilted state.

If a ball enters between the opening and closing pieces 3, 3 while the opening/closing pieces 3, 3 are maintained tilted in this way, the opening/closing pieces 3, 3 are once raised up due to the weight of the ball, and at the same time, the opening/closing pieces 3, 3 are raised up along with the rising movement. The ball guiding plate 9 that is not connected also overcomes the repulsion by the electromagnet 15 and the permanent magnet 12 and lowers the front end, but the ball does not reach the ball entrance 2.
As the ball flows out from the lower part of the ball, the bias due to the weight of the ball is released, and the ball guiding plate 9 immediately moves to the opening actuating lever 13. due to the repulsive force of the permanent magnet 12. The opening/closing pieces 3, 3 are returned to the original tilted position via the projection 11 and tilted again.

That is, as long as the electromagnet 15 is in the excited state, even if a ball enters between the tilted opening and closing pieces 3, 3, the ball guide plate 9 will be repulsed by the permanent magnet 12 and will remain in the tilted state without being erected. It continues to be maintained.

When the electromagnet 15 is de-energized and demagnetized, the mutual repulsion with the permanent magnet 12 is also eliminated, and the ball guide plate 9 is released from the bias caused by the repulsion, so that the front end of the electromagnet 15 is removed as the opening/closing piece 3°3 moves upright. lower and hold the position.

Thereafter, as long as the electromagnet 15 is not energized, the opening and closing pieces 3, 3 are alternately raised and tilted without any trouble, just as in the ball receiving machine of conventional function.

As described above, the present invention includes an electromagnet and a permanent magnet that is repelled by the excitation of the electromagnet, in a ball socket that has the function of causing the opening and closing pieces to rise and tilt alternately when a ball enters. The opening/closing lever is attached to the opening operating lever, and the opening/closing piece is kept in a tilted state as long as the electromagnet is excited, so despite its simple structure, it is rich in variety and increases the interest of pachinko games. be able to.

In addition, the winning probability is significantly increased compared to conventional ball sockets, which improves the service to players, makes pachinko even more interesting, and helps to retain players. The effect is truly great.
