Abstract

PURPOSE:To make a dice dance only with an arranged coil for simplifying the assemblage of a mechanical device by providing a plurality of dice incorporating a magnet on a dice receiving tray and a power supply circuit for supplying AC current to a coil arranged on the rear of the dice receiving tray for a required time. CONSTITUTION:Diecs 41 incorporating one or a plurality of magnets 43 are mounted on a die receiving tray 35 and about several hertz of AC current are applied from a power supply circuit to a coil 37 arranged on the rear of the die receiving tray 35 for about 10 seconds for example. The AC current of proper wave form may be used to reverse the direction of the current and the polarity of a magnetic pole generated in the coil 37. While the magnetic pole is generated thus in a specified spot of the dice receiving tray 35 by the coil 37, the polarity is reversed by applying the AC current to the coil 37 in the same way as the magnetic pole is reversed, so that the dice 41 are capable of dancing by the attraction and repulsion of the coil 37.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to roll one or a plurality of dice a required number of times by inserting coins, and further roll the dice depending on the number of dice rolled. The present invention relates to a game machine that continues a dice game.

[0002]

2. Description of the Related Art Today, there is a game in which a plurality of dice are mechanically danced and the game is advanced by combining the dice. This dice game machine, for example, when using dice, as shown in FIG. 8, a landing 11 provided with a large number of small holes 12, a show hall 15 horizontally continuous from the landing 11, and a V-shaped groove. Some of them have a return groove 17 formed therein, and in the landing 11, the rod-shaped projections provided below the landing 11 are projected irregularly from the small holes 12 to roll the dice 41 such as dice, and after a required time, The photo sensor 29 is used when sliding the sight 15 from the landing 11 so as not to change the surface and dropping it into the return groove 17 which is a V-shaped groove, and when the die 41 is pushed back along the V-shaped groove.
There are some that read the eyes that come out.

Further, as shown in FIG. 9, when a die 41 such as a dice moved to the upper stage 23 by the lifter 21 is mechanically vigorously thrown to the lower floor 25 to roll the dice, the dice is returned to the lifter 21. There is also a device in which the sensor 29 is used to confirm the eyes. In addition, when confirming the roll of the dice, not only when the position of the face and the number of the faces are searched using the image sensor 29 or the like, magnets of different sizes are provided on each face of the dice. The one that checks the appearance by the size and polarity of the magnet (for example, Japanese Examined Patent Publication No. 56-34310, Japanese Examined Patent Publication No. 57-32829).
No.) is also available.

Further, a game machine for shooting a dice by using a CCD camera or the like, searching for an eye that has appeared on the basis of the image data, and displaying the image of this eye on a CRT to progress the game. In such a game machine, in addition to visually recognizing the movement of the dice thrown on the show hall 15 or the lower floor 25, the upper surface of the dice is CCD-scanned by a CCD camera mounted above the show hall 15 or the lower floor 25. The bit pattern taken by the CCD camera is searched for an image to determine the roll of the dice. The motion of the dice can be seen with the naked eye, and the bit pattern shot by the CCD camera is used to search. The image of the dice is displayed on the CRT, and the score is appropriately increased or decreased depending on the searched dice to continue the game.

[0005]

As described above, in order to make the movement of the die irregular, the mechanical structure for pushing up the dice such as dice to make it dance is a combination of complicated cams and links. In many cases, the mechanical structure of the structure for throwing the dice becomes a little complicated, and a space for rolling the dice is required, which has a drawback that it is difficult to save space. It is often necessary to have a mechanism for returning the dice to the position where they can dance or throw out, and it has been difficult to miniaturize the game machine.

[0006]

According to the present invention, a die containing a magnet is placed in a die pan, a coil is provided on the back surface of the die pan, and a power supply circuit for applying an alternating current to the coil for a required time is provided. . Further, a plurality of coils may be provided on the back surface of the dice tray, and an AC power supply circuit may be provided for each coil.

Further, as means for confirming the eyes of the dice, a CCD camera is provided above the dice tray so that the eyes of the dice can be confirmed by image processing.

[0008]

[Operation] According to the present invention, a magnet is built into a die placed in the die saucer, and an alternating current is applied to a coil provided on the back surface of the die saucer. You can Further, when a plurality of coils are provided, it is possible to complicate the change of the magnetic force lines generated by each coil and change the movement of the die.

Further, in the method of confirming the eyes of the dice using the CCD camera, it is not necessary to dispose a detecting element or the like around the die tray, and the mechanism around the tray can be simplified.

[0010]

EXAMPLE An example of the present invention has a switch panel 31 as shown in FIG. 1 and a dice game while visually observing a die 41 placed inside a dice tray 35 through a glass window 33. This is a game machine to be played, in which a coil 37 is provided on the back surface of the dice tray 35, and an alternating current can be applied to the coil 37.

Then, as shown in FIG. 2, the die 41 placed on the die tray 35 has a magnet 4 at the center of the die 41.
3 is inserted, or as shown in FIG. 3 or 4, a magnet 43 is inserted at a position outside the center of the die 41 so that the center of gravity of the entire die 41 is returned to the center of the die 41. There is a type in which a balancer 45 made of a material that does not have a whitish is combined and embedded in the die 41.

Further, as shown in FIG. 5, a plurality of magnets 43 may be embedded in the die 41, and there may be a plurality of die surfaces each having a polarity of N pole or S pole. In this case, the magnets 4 are arranged so that the opposite surfaces have opposite polarities.
3 and the embodiment shown in FIG. 5 is a regular hexahedron die 41.
In the case of, the three faces are the N pole and the remaining three faces are the S pole,
2 faces are N poles, 2 faces facing N poles are S poles, and the remaining 2
It is also possible that the surface has no magnetic pole.

As described above, the die 41 containing one or a plurality of magnets 43 is placed on the die pan 35, and an alternating current of about several tens of hertz is applied to the coil 37 arranged on the back surface of the die pan 35. For example, about 10 seconds are applied from the power supply circuit. As this alternating current, a sine wave, a square wave, a sawtooth wave or the like having an appropriate waveform can be used, but the direction of the current is reversed and the polarity of the magnetic pole generated in the coil 37 is reversed. It is generally preferred to use frequencies below 100 Hertz.

In this way, the magnet 43 is embedded in the die 41, the coil 37 is provided on the back surface of the die tray 35, and the magnetic pole is generated by the coil 37 at a specific position of the die tray 35 and the magnetic pole is reversed. Since an alternating current is applied to the coil 37 to cause polarity reversal, the die 41 can be made to dance by the attraction force and repulsive force with the coil 37.

Further, in the die 41 in which a plurality of magnets 43 are embedded in the die 41 to form N poles and S poles on a plurality of surfaces of the die 41, when a current in one direction is applied to the coil 37, Since there are a plurality of suction surfaces of the dice 41, the eyes of the dice 41 are uncertain, and it is possible to change the possibility of each eye. Furthermore, when arranging the coil 37 on the back surface of the dice tray 35,
In addition to the case of arranging only one ring-shaped coil 37 shown in FIG. 2, a case of arranging two or three coils, or as shown in FIG. If the coils 37 may be arranged, and each coil 37 is provided with a separate power supply circuit so that an alternating current can be applied, the position of the magnetic pole generated by each coil 37 is located at the die saucer 35. Changes with time, and the movement of the die 41 can further change.

Further, in this embodiment, the CCD camera 27 is arranged above the dice tray 35, and the image of the dice 41 taken by the CCD camera 27 is used to electrically discriminate the eyes of the dice 41 and the game is executed. It is possible to proceed, CCD
It is assumed that the discrimination based on the image of the camera 27 is started at least 10 milliseconds after the power supply to the coil 37 is stopped by the power supply circuit.
It is possible to prevent noise from being generated in the image taken in and to make a mistake in discrimination.

The dice 41 are not limited to hexahedron dice, but those having appropriate patterns on each side are used, and
It is also possible to use a die 41 having a regular dodecahedron or regular dodecahedron.

[0018]

According to the present invention, a magnet is embedded in a die, and an alternating current is caused to flow in a coil provided on the back surface of the die tray to cause the reversal of the magnetic pole, and the magnetic pole between the coil and the magnet embedded in the die is separated. Since the dice are caused to dance by the suction force and the repulsive force generated in the above, the die can be caused to dance only by disposing the coil below the saucer, and the assembly of the mechanical device can be simplified.

If a CCD camera is provided above the dice tray and the eyes of the dice are confirmed by the image of the CCD camera, the progress of the game can be judged without using a mechanically complicated mechanism. Can be easily miniaturized.
