Abstract

Abstract A roulette device which has the object of being able to automatically perform the operation required to play roulette in practice. When a start switch is closed, a rotary disc (9) rotates normally, thereby throwing a ball (24) made of a magnetic material onto a rolling passage formed along a ball rolling member (7). A number of sensors (P 1 , P 2 , P 3 ...) for detecting the passage of the ball and electromagnets (M 1 , M., M 3 ...) energized in sequence by outputs of the sensors are arranged along the passage, and the ball is gradually accelerated by the attraction forces of the electromagnets so that it rolls along the passage. The disc is rotated in reverse when the ball is thrown into the passage, and therafter idles in reverse. When the Nergization of the electromagnets is broken, the ball is gradually decelerated, the rolling radius is reduced, the ball then rides on the disc, and is stopped in a certain pocket (10). The betting number is written on the pocket. The roulette device can be installed mainly as a games machine in a games center or sports ground, but when it is fabricated to a small size, it can become a roulette toy capable of being played in domestic situations.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 226 words
A roulette gaming apparatus comprising: a ball; a ball rotating apparatus having an inwardly declivity-type annular ball rotating passageway; and a rotary disk which is rotatably mounted in the inside of said ball rotating passageway coaxially therewith and has a plurality of pockets adapted to receive the ball thrown from said ball rotating passageway, wherein said ball being made of magnetic material, said ball rotating apparatus being constituted by a ball rotating member having said ball rotating passageway, a plurality of sensors arranged along said ball rotating passageway for detecting the passing of said ball, a plurality of electromagnets provided corresponding to said sensors for applying a magnetic force to the ball in accordance with a signal from the corresponding sensor, rotating the ball in a given direction, and a control circuit which can apply a pulse-like current to the corresponding electromagnet in response to the output of said sensor, and a rotary disk driving apparatus being further provided which first rotates said rotary disk in the rolling direction of said ball, and which rotates the ball in the direction opposite to the direction at the starting time of rotation after the ball in the pocket has been thrown onto said ball rotating passageway, and which further races the rotary disk at about the time when the driving of the ball by said electromagnets is stopped.
Claim 2
Dependent Claim 226 words
A roulette gaming apparatus comprising: a ball; a ball rotating apparatus having an inwardly declivity-type annular ball rotating passageway; and a rotary disk which is rotatably mounted in the inside of said ball rotating passageway coaxially therewith and has a plurality of pockets adapted to receive the ball thrown from said ball rotating passageway, wherein said ball being made of magnetic material, said ball rotating apparatus being constituted by a ball rotating member having said ball rotating passageway, a plurality of sensors arranged along said ball rotating passageway for detecting the passing of said ball, a plurality of electromagnets provided corresponding to said sensors for applying a magnetic force to the ball in accordance with a signal from the corresponding sensor, rotating the ball in a given direction, and a control circuit which can apply a pulse-like current to the corresponding electromagnet in response to the output of said sensor, and a rotary disk driving apparatus being further provided which first rotates said rotary disk in the rolling direction of said ball, and which rotates the ball in the direction opposite to the direction at the starting time of rotation after the ball in the pocket has been thrown onto said ball rotating passageway, and which further races the rotary disk at about the time when the driving of the ball by said electromagnets is stopped.
Claim 3
Dependent Claim 29 words
The roulette gaming apparatus according to claim 1, further comprising sensor means for detecting the ball when the ball has been caught in said pocket on said rotary disk.
Claim 4
Dependent Claim 45 words
The roulette gaming apparatus according to claim 2, further comprising an computing and control circuit for computing a repayment amount in accordance with the wagered numeral and the number wagered coins in response to an output from said sensor means, and a coin repayment mechanism.
