Non-contact counter

摘要

An apparatus for the non-contacting counting of newspapers and the like which are being transported in shingled or overlapped relationship by a continuous conveyor system, which apparatus includes, a source of radiant energy positioned to direct a stream of energy against the surface of the overlapped moving papers, energy sensors positioned to receive energy reflected from the surfaces of the papers at a plurality of locations and means responsive to the output from the sensors to derive a signal indicative of the number of papers passing beneath the source of radiant energy.
