Object of the Invention
[0001] The present invention relates to a drawing mechanism, specifically a mechanical-electronic
device intended to be associated to one or more gaming machines with similar or different
characteristics for the purpose of forming an additional game for the same.
[0002] The object of the invention is to provide a drawing mechanism which allows varying,
by means of regulation provided for such purpose, the probability of winning, all
according to reducing or increasing the value of the prizes.
Background of the Invention
[0003] Drawing mechanisms for gaming machines, such as in the case of the known casino roulettes,
in which the number of probabilities of winning is fixed and cannot be varied are
known. This brings with it a drawback which fundamentally focuses on the fact that
when it is necessary to increase the value of the prize corresponding to the winning,
in order to balance said increase without modifying the value of the bet, it is necessary
that the probabilities of winning by the player are reduced.
[0004] However in order to achieve this objective it is necessary to physically modify the
drawing mechanism, the total replacement of said mechanism for another mechanism specifically
designed according to the probabilities of winning required in the plays being necessary
in some cases, with the consequent economic cost which that involves.
[0005] Although there are entertainment machines which allow automatically modifying the
probabilities of winning in a certain game, it relates to purely electronic games,
i.e., said modifications are carried out as a result of programming software, selecting
between different options. The problem which these types of machines have is that
the user, in this case the player, has to trust the "randomness" of the game process,
which is controlled as has been previously said by a certain programming software,
said player not being able to check for himself, as occurs in the "physical" game
mechanisms, that said randomness is completely real.
Description of the Invention
[0006] The drawing mechanism with a variable regulation device for regulating the probabilities
of winning proposed by the invention fully and satisfactorily solves the drawbacks
previously set forth in the different mentioned aspects.
[0007] Said mechanism is formed by a drum-shaped receptacle, ball container and mixer, provided
with a device with the capacity of randomly reading and identifying each and every
one of the balls contained therein. It is for that reason that the mechanism and device
are able to:
■ Randomly choose and set aside one ball from among a group of balls enclosed in a
drum.
■ Identify and read the chosen ball.
■ Return the ball set aside again to the grouped set of all balls.
■ Send orders for rotating in both directions to the drum for mixing the balls contained
therein, or set aside one of the balls for its display and reading, as the case may
be.
[0008] This and other objectives of the invention are achieved by means of a mechanism according
to claim 1. The particular embodiments of the mechanism object of the invention are
defined in dependent claims the 2 to 11.
[0009] More specifically, the proposed mechanism, intended to be associated to two or more
entertainment machines, all of them forming a type game table or counter, is formed
from a drum, in which a predetermined number of balls are arranged, which drum could
be transparent or like a cage, for allowing in any case the player or players in question
to see the balls contained therein, provided with fixing means for fixing it to the
mentioned game table with a horizontal rotating shaft arranged inside the drum and
in which a motorized drive mechanism is arranged which allows rotating the drum in
either direction.
[0010] Said drum equally has a protrusion in the shape of a protruding turret located on
a plane of symmetry perpendicular to the rotating shaft, and with suitable dimensions
for allowing the passage and housing therein of at least one of the balls.
[0011] Said turret includes in its base a mechanism for opening and closing the access of
the balls to the same turret for the purpose of allowing the entrance or exit of the
balls; said mechanism consists of a pivoting blade, balanced such that the rotation
of the drum in one direction makes the blade pivot, closing through one of its ends
the entrance of balls to the turret , whereas the rotation in the opposite direction
of the drum equally causes a pivoting of the blade in the opposite direction, such
that the end thereof preventing the entrance of the balls clears the passage of the
ball to the inside of the turret.
[0012] Nevertheless the mentioned turret could be oversized in length for optionally allowing
the entrance of two balls.
[0013] Said balls will have their outer surface printed with the corresponding number or
illustration, being equally provided with an inner circuit for identification by means
of an electronic reader associated to the control circuit of the support of the entire
drawing mechanism assembly.
[0014] Thus, and by means of the mentioned electronic reader, the mechanism of the invention,
as has been previously mentioned, can be associated to an assembly of two or more
betting terminals provided with means for managing charges and payments, as well as
managing the development and display of the results of the plays in the form of drawings.
[0015] According to the essential features of the invention, when the probabilities of winning
the bets are to be varied, it will only be necessary, as the case may be, to reduce
or increase the number of balls housed within the drum, and introduce the data relating
to the new number of balls into the electronic part of the device, a process which
is carried out is an extremely simple manner, by means of accessing the inside of
the drum for the purpose of ordering the new number of balls, an operation which is
carried out with the opening of the drum, operating on the corresponding mechanism
provided in the assembly for such purpose; having as complement to the previous operation,
the access to the test program and the actuation of the controls which allow setting
the type of the desired game. Once this operation is carried out, the device is completely
automatically in charge of compensating the new order of probabilities of winning.
[0016] The control circuit or CPU of the device will thus be electrically associated: to
the mechanism for rotating the drum, controlling both its rotation/stopping and its
position; to the means for identifying the balls; as well as to the rest of the conventional
electronic elements taking part in the drawings; transmitting said data to the assembly
of machines to which the drawing mechanism is associated, machines in which each of
them will have its corresponding means for executing its own games and which eventually
and particularly will be able, independently or simultaneously at the will of the
player, to access the information and use the data of the result of the drawings carried
out by means of the mechanism to make bets, whereby the player of each machine can
bet what he or she thinks suitable, regardless of the rest of the players.
[0017] An extremely versatile mechanism is thus achieved which can be implanted in association
with different types of machines, and which allows changing the probabilities of winning
in the drawing carried out by the same in an extremely quick and simple manner without
needing to modify the structure of the assembly.

[0020] In view of the indicated figures, and especially Figures 1 and 2, it can be observed
how the drawing mechanism proposed by the invention, which in the chosen practical
embodiment in Figure 1 is integrated into a game table (1) but could equally be associated
to different types of entertainment machines and for a different number of machines
and players without affecting the essence of the invention, is formed from a spherical
drum (2) which in the example of the figures is carried out as a type of cage which
allows seeing the balls (3) housed therein, but which could equally be carried out
as a sphere of plastic material or any other transparent material.
[0021] Said drum (2) is fixed to the game table (1) from a pair of vertical arms (4), or
any type of raised platform which allows supporting a horizontal rotating shaft (6)
at the desired height, carried out as a cylinder inside which an electric motor (12)
and the corresponding mechanism associated thereto are arranged in order to allow
carrying out the rotation of said drum (2) in either direction, as well as an electro-optical
sensor (32) as a controller and detector of the position of the drum (2) and which,
acting on a spur located in the shaft/motor, sends the necessary data to the CPU so
that the orders corresponding to the motor (12) on starting, breaking and rotation
direction can be sent.
[0022] Said drum (2) has a protrusion in the shape of a turret (10) provided on the plane
of symmetry perpendicular to the rotating shaft (6) thereof, said turret (10) forms
an integral part with the outer structure of the drum (2) and is sized such that it
allows housing a ball at its distal end (11) when the circumstance of the game requires
it.
[0023] The balls (3) will have an identification printed on their outer surface so the players
can see said information, whereas they will internally have an identification circuit
for being identified by means of an external electronic reader (13) associated to
a control circuit or CPU (14) through which it is connected with the different machines
taking part in the game table, which circuit will be further described below.
[0024] The mentioned turret (10) is provided with a mechanism (8) which allows controlling
the entrance of the balls (3) to its inside as well as the exit thereof for joining
the rest of the balls in the drum (2) depending on the rotation direction thereof,
such that rotating the drum in one direction provided that the turret does not house
a ball (3) inside, allows the passage of a ball of those contained in the drum, after
which it maintains said ball inside preventing its exit, whereas if the rotation of
the drum (2) occurs in the opposite direction, the turret allows the exit of the ball
contained therein, preventing the entrance of a new ball.
[0025] Therefore the mechanism (8) for controlling the entrance and exit of the balls to
and from the turret (10) has a blade (15) pivoting on a shaft (16), with suitable
dimensions and shape so that it is balanced such that by turning the turret (10) in
one rotation direction of the drum (2), an end (17) thereof pivots due to gravity,
closing at its other end (18) the access to any ball (3), whereas when a rotation
of the drum in the opposite direction occurs, the pivoting of the blade (15) equally
occurs in the opposite direction, allowing the exit of the ball (3) from the turret
(10), and preventing the entrance thereto of a new ball through its lower end (17),
as can be observed in Figures 3 and 4. Likewise, the mechanism (8) has side supports
(7) for the shaft (16) of the pivoting blade (15).
[0026] The turret (10) can optionally have a longer length for housing a second ball therein,
equally preventing the entrance of more balls for the purpose of providing a second
prize or larger prize corresponding to two results in a single drawing.
[0027] Thus, and as has been previously mentioned, by varying the number of balls (3) housed
in the drum (2) and entering in the CPU of the variable regulation device, through
its test program, the data corresponding to the new number of balls, the probabilities
of winning in the drawings can be varied in a quick and simple manner without having
to modify the structural features of the device.
[0028] The CPU (14) will be equally in charge of controlling the power supply of decorative
lighting elements (24) provided in an information panel (25) located next to the drum
(2), and on which an alphanumeric panel (26) is contained with the data which is considered
of interest in the plays; it will likewise be in charge of generating audio signals
(27) and (34) for information of the game in the terminals and in the central unit,
giving betting permission (29) to the terminals which wish to take part in the drawing
and supplying them before each play with information of the number of balls (30) taking
part in each drawing, as well as validating by means of the control (28) the activation
of the device by means of the existence of credits in the machines.
[0029] Said CPU (14) will similarly be associated to a control circuit (32) for controlling
the position of the turret (10), having a push-button control (33) for accessing the
regulation/validation test for regulating/validating the balls in the game, as well
as an auxiliary push-button control (31) for fixing the adjustable variations.
