Display device and double drum for gambling machines

Abstract

The invention is structured on the basis of two flywheels ( 14 ) and ( 17 ) which are coaxial and having different diameters, upon which respective annular bands ( 15 ) and ( 18 ) are assembled, which are concentric and consequently parallel, bearing their respective alignments of images or figures that are collated with empty and transparent areas permitting the visualization of the inner band through the outer band, said bands having independent actuation by means of respective motors ( 13 ) and ( 19 ), in turn controlled by respective optic regulators ( 23 ) and ( 24 ), such that the movement of one of the annular and image-bearing bands ( 25 ) is totally independent from the other ( 28 ).

1 .—display for roulettes or drums in recreational machines, of the type incorporating a mobile plate closed in on itself bearing a plurality of figures, a plate that is partially visible through the screen of the machine, showing at least one image at the end of each play that can be combined with that of the other displays in order to obtain a prize winning combination, displays wherein behind the area of the screen of the machine through which the figures are visible, there is a reflective screen having recesses that are dimensionally and positionally in coincidence with the visible figures on the mobile plate, at the bottom of which there are lights for enhancing the visualization of said figures, characterized in that at least one of said lights ( 5 ) incorporates a complementary signaling device ( 6 ) of any suitable, conventional type, such as a display, which is unnoticed when inoperative and which provides complementary information through the mobile plate ( 1 ) when operative, information that is a number or any other type of figure modifying the conditions of the game, changing the value of the prize obtained in the winning line or permitting access to an auxiliary game.  
   
   
       2 .—Display for roulettes or drums in recreational machines according to  claim 1 , characterized in that the mobile plate ( 1 ) bearing the Figures ( 2 ) that are sequentially visible through the screen of the machine incorporates a transparent or less opaque area in correspondence with each one of said Figures ( 2 ), which is formally and dimensionally suitable for permitting better visualization of the information provided by the subsequent signaling device when it is operative.  
   
   
       3 .—Display for roulettes or drums in recreational machines according to  claim 1 , characterized in that it comprises two coaxial flywheels ( 14 ) and ( 17 ) but with independent actuation, having slightly different diameters, each one of which constitutes a support and mobilizer means for an annular band ( 15 - 18 ) bearing a plurality of uniformly distributed images ( 28 - 30 ) which are intercalated with transparent sectors ( 29 - 31 ), such that after the double drum stops and through the corresponding outer screen or window, the images of the band ( 15 - 18 ) adopting the outer position are visible, and where applicable and through the transparent sectors ( 29 - 31 ) thereof, images of the band ( 15 - 18 ) adopting the inner position.  
   
   
       4 .—Display for roulettes or drums in recreational machines according to  claim 3 , characterized in that the main flywheel ( 14 ) is joined to the output shaft ( 16 ) of an electric motor ( 13 ) assembled in a cylindrical support casing ( 12 ) joined to a support chassis ( 11 ) for the entire assembly, said motor ( 13 ) being coaxial to the drum, whereas the secondary flywheel ( 17 ) is assembled with rotational freedom on the cylindrical support ( 12 ) and receives the movement through a toothed crown ( 22 ) from a second motor ( 19 ) that is independent from the motor ( 13 ), assembled on a radial extension ( 20 ) of the support ( 12 ) and whose output pinion ( 21 ) meshes with said crown ( 22 ).  
   
   
       5 .—Display for roulettes or drums in recreational machines according to claims  3  and  4 , characterized in that the optic regulator ( 23 ) is established on the radial extension ( 20 ) for the secondary motor ( 19 ) in order to control the main flywheel ( 14 ), whereas the optic regulator ( 24 ) for the secondary flywheel ( 17 ) is established on another radial extension of the cylindrical support ( 12 ).  
   
   
       6 .—Display for roulettes or drums in recreational machines according to claims  3 ,  4 , and  5 , characterized in that the main band ( 15 ) associated to the main flywheel ( 14 ) can be placed inside or outside of the secondary band ( 18 ) associated to the secondary flywheel ( 17 ).  
   
   
       7 .—Display for roulettes or drums in recreational machines according to claims  3 ,  4 ,  5  and  6 , characterized in that the radial extension ( 25 ) constituting the support for the multiple screen ( 16 ) containing the lighting lights ( 27 ) is placed opposite the extension ( 20 ).
