Abstract
Abstract The apparatus of this invention is designed to display information comprised of any one of a number of predetermined light spot pattern formation in any one of a number of predetermined colors. One example of its usefulness is set forth herein as a display means representative of an upturned face of a die for use in games of chance requiring not only a showing of one or more spots, but in addition showing the spots in different colors.

Light spot pattern formation and color control apparatus comprising: a. a light source; b. first, second and third light passage control members; c. axle means supporting said first and second members, respectively, for rotation thereof one with respect to the other and each with respect to said third member and to said light source, said first and second members being intermediate said third member and said light source; d. indexing means for indexing said first and second members, respectively, in any one of a plurality of index positions with respect to said third member upon rotation thereof; e. said first member having a plurality of light attenuating means each controlling the color of light upon passing therethrough from said light source; f. said second member having a plurality of predetermined positioned window means therethrough each controlling the pattern of light upon passing therethrough from said light source; g. said third member presenting a display surface and having window means therethrough to said surface; h. said indexing means effecting an optical alignment of an individual one of said light attenuating means of said first member, an individual one of said window means of said second member, and said window means of said third member, whereby the different hue and pattern of light spot formations presented at the display surface of said third member is dependent upon the indexing of said first and second members with respect to said third member, the indexing means of said first member including predetermined arrangement of magnetic material means supported thereby and reference magnetic element means fixedly supported in relation thereto for magnetically influencing the stoppage of said first member and thereupon effecting the optical alignment of one of said attenuating means with the window means of said third member, and the indexing means of said second member including predetermined arrangement of magnetic material means supported thereby and reference magnetic element means fixedly supported in relation thereto for magnetically influencing the stoppage of said second member and thereupon effecting the optical alignment of one of said window means thereof with the window means of said third member.
