ABSTRACT:
A lite-counting apparatus counts lites in a longitudinal array. During a traversal by the apparatus of a peripheral portion of the array, a beam of radiation is passed from at least one source to at least one detector. Based upon changes in the relative path taken by the beam, the articles may be counted.
