Token having predetermined optical characteristics and a token validation device therefor
First Claim
1. A token for use with a token operated device comprising a plurality of predetermined optical characteristics, said plurality of predetermined optical characteristics being disposed in a substantially radially symmetrical manner with respect to said token, and each of said optical characteristics having the property of a facet wherein an effective surface normal of said facet is aligned along a predetermined vector angle with an elevation angle ranging substantially between 30°
- and 60° and
an azimuthal angle other than substantially along a radial line of the token or substantially along a line tangent to an annular ring centered on the token such that said token operated device can validate said predetermined optical characteristics substantially independent of token orientation.

Abstract
A token for use with a token operated device includes a plurality of predetermined optical characteristics. The plurality of predetermined optical characteristics are disposed in a substantially radially symmetrical manner with respect to the token, and each of the optical characteristics have the property of a facet wherein an effective surface normal of said facet is a line along a predetermined vector angle with an elevational angle ranging preferably between 30° and 60°. An azimuthal angle of the facet surface is other than substantially along a radial line of the token or substantially along a line tangent to an annular ring centered on the token such that a token operated device can validate the predetermined optical characteristics substantially independent of token orientation. A token testing apparatus includes a chute defined by a field adjustable pair of spaced token edge guides spaced a predetermined distance from each other such that each token passing through the chute is sensed along its center.

19. A token comprising a face having a plurality of predetermined optical characteristics disposed between circular lines defining therebetween a substantially annular band relative to a center A with each optical characteristic being curved relative to a chord line passing through a reference point X in said annular band through which also passes a radius of the token, the chord line and radius defining an included angle θ
- , and successive optical characteristics are formed in the face by rotating the token about its center A by a rotation angle RT defined by the equation ##EQU2## where d is the perpendicular distance between said predetermined optical characteristics and AX is the length of the radial line between the center A and the reference point X.
