DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-and-ball game machine, and more particularly, to an inclined surface provided on a lower side of a symbol display device and an accessory thereof.

[0002]

2. Description of the Related Art Conventionally, a so-called center case is sometimes provided on a front surface of a symbol display device in a ball game machine. The center case is provided for the purpose of changing the path of a game ball to enhance game characteristics. The center case is generally provided with an inclined plate.

[0003]

However, in the prior art, the game ball moves monotonously on the inclined plate, so that the change in the movement is poor and the game property is lacking.

Accordingly, an object of the present invention is to provide a ball game machine capable of giving a surprising change in the rolling direction of a game ball to further enhance game characteristics.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems. Firstly, a game ball which has flowed from a game board surface is moved and then turned to the game board surface again. A ball game machine having an inclined surface portion for dropping the game ball, wherein magnetic means for changing the rolling direction of the game ball on the inclined surface portion is provided. Therefore, since magnetic force means for changing the rolling direction of the game ball on the inclined surface portion is attached, the change in the rolling direction of the game ball that has reached the inclined surface portion is performed, and the movement of the game ball cannot be predicted. It is possible to enhance game characteristics.

Secondly, in the first configuration, the game board is provided with a center case, and the center case is provided with the inclined surface portion and the magnetic force means. Therefore, since the magnetic means is provided integrally with the center case, there is no need for a separate step of attaching the magnetic means when attaching to the game board.

[0007] Thirdly, in the first or second configuration, the magnetic force means is movable by electric power. Therefore, the magnetic field can be sequentially changed, and since the moving direction of the game ball changes in an unexpected direction, the moving direction of the game ball cannot be predicted,
It is possible to further enhance the game characteristics.

a, nails 67b are provided.

Next, the operation and effect of this embodiment will be described. When the motor 72 is driven, the magnet support 74 rotates. As the magnet support 74 rotates, the permanent magnet 76 attached to the tip of the magnet support 74 also moves, so that a magnetic field changes on the inclined surface 42d.

A game ball P fired by a firing device (not shown) reaches a game area of the game board 20 and enters warp entrances 52a and 52b in some cases. This warp entrance 52
a, 52b enter the game ball passage 54a, 5b.
After passing through the warp outlets 56a and 56b through 4b, it appears on the inclined surface 42d. Then, since the inclined surface portion 42d is inclined forward and downward at an angle θ with respect to the horizontal direction, the game ball P rolls forward. At this time, under the influence of a change in the magnetic field on the inclined surface 42d caused by the rotational movement of the permanent magnet 76, the play path of the game ball P changes as shown by an arrow in FIG. 5, for example. The magnetic force of the permanent magnet 76 is strong enough to prevent the game ball P from falling on the inclined surface 42d. The game ball P dropped from the inclined surface portion 42d passes between the nails 67a and 67b, and
Or fall in the game area of the game board 20.

According to the ball game machine A1 in this embodiment, since the rolling unit 70 is provided, the game ball P moving on the inclined surface 42d moves in the moving direction by the magnetic force from the rolling unit 70. Is changed and the game ball P
It is possible to improve the game characteristics as the movement of the game cannot be predicted. In particular, the rotation of the magnet support 74 to which the permanent magnet 76 is attached changes the magnetic field on the inclined surface 42d sequentially, so that the game ball P moves in an unexpected direction and the movement of the game ball P cannot be predicted. , The game characteristics can be further improved. In particular, since the rolling unit 70 is hidden under the inclined surface 42d, it is not possible to predict in which portion on the inclined surface 42d the rolling direction of the game ball will change in which direction. Will increase. Also, by using the permanent magnet 76, a simple and inexpensive magnetic means can be used.

Next, a description will be given of a ball game machine according to a second embodiment. The ball game machine A2 according to the second embodiment has substantially the same configuration as the ball game machine A1 according to the first embodiment, except that the ball game machine A1 according to the first embodiment has an inclined surface portion 42.
While a permanent magnet is used as a magnetic force for exerting a change in the magnetic field on d, the ball game machine of the second embodiment is different in that an electromagnet is used.

That is, as shown in FIG. 6, a plurality of magnetic force units 80 as the magnetic force means are provided on the inclined surface 42d. That is, the magnetic force unit 80
Inside, an electromagnet in which a coil is wound around an iron core is provided. The number, size and shape of the magnetic force units 80 are such that they do not hinder the game balls P passing on the inclined surface 42d,
In addition, it is set to such an extent that it does not hinder the visual recognition of the symbol display device 60.

Next, the operation and effect of this embodiment will be described. A magnetic field is generated on the inclined surface 42d by appropriately supplying a current to each magnetic force unit 80 attached to the inclined surface 42d. In particular, by randomly changing the magnetic force unit 80 that conducts electricity, the magnetic field changes randomly.

Therefore, the game ball P appearing on the inclined surface portion 42d from the warp outlets 56a and 56b rolls on the inclined surface portion 42d inclined forward at an angle θ, and the magnetic field generated by the magnetic force unit 80. , The movement route changes. Further, the magnetic force unit 80 is also provided on the inclined surface portion 4.
Since it is projected above 2d, the moving path of the game ball P changes even when the game ball P comes into contact with the magnetic force unit 80.

As described above, since the magnetic force unit 80 is provided, the game ball P moving on the inclined surface 42d is
A change in the moving direction is given by the magnetic force from the magnetic force unit 80, and it is possible to enhance the game property as the movement of the game ball P cannot be predicted. In particular, by randomly changing the magnetic force unit 80 that conducts electricity, the magnetic field on the inclined surface 42d also changes sequentially, so that the game ball P moves in an unexpected direction and the movement of the game ball P cannot be predicted,
The game characteristics can be further improved. As for the plurality of magnetic units 80, for example, the plurality of magnetic units 80 may be continuously energized simultaneously, or the energized magnetic units 80 sequentially energized may be changed.

In the above description of the second embodiment, the magnet unit 80 provided with the electromagnet is mounted on the inclined surface 42d.
Although it has been described as projecting upward, the present invention is not limited to this. The plurality of magnet units 80 are not protruded from the inclined surface portion 42d, but are provided below the inclined plate portion forming the inclined surface portion 42d. Is also good. That is, the plurality of magnetic force units 8
A magnetic force generating device provided with 0 is provided below the inclined surface portion 42d, and the electromagnets in the plurality of magnetic force units 80 are energized and driven.

As for the plurality of magnetic units 80, the plurality of magnetic units 80 may be continuously energized simultaneously, the magnetic units which are energized sequentially may be changed, or they may be changed randomly. You may do so.
Further, an electromagnet may be attached in place of the permanent magnet 76 in the rolling unit 70 in the first embodiment, and the electromagnet may be rotated to change the magnetic field.
