Abstract:
Apparatus for testing tokens of varied diameters comprising opposite walls in part defining a chute through which a token is adapted to pass, a pair of spaced token edge guides between said opposite walls and further defining therewith said chute, said edge guides being spaced a substantially predetermined distance from each other corresponding substantially to the diameter of a token passing through said chute whereby each token axis moves along a center line of a centered token path of travel corresponding to substantially one-half said substantially predetermined distance, first token characteristic sensing means for sensing a first token characteristic during token movement along said token path, said first token characteristic sensing means being constructed and arranged for sensing each token substantially along said token path center line whereby on-axis token sensing is effected, and means for changing the perpendicular distance between said edge guides while maintaining token path center line sensing thereby adapting the same testing apparatus for sensing tokens of different diameters.
