Abstract
Documents are fed from an infeed through a stripper one at a time. Documents leaving the stripper are accelerated to provide a suitable gap between documents. A light source and phototransistor are used to count the documents. The phototransistor picks up the light passing through the documents as well as light between documents. Plural counters count in a mutually exclusive fashion, said counts representing document length and gap length between documents to count the documents to distinguish between 'normal' gap lengths and perforations, tears and the like within documents, to detect the presence of overlapping or abnormally 'long' documents to provide an accurate count and to terminate document feeding. The counters mutually exclusively develop counts during the presence and absence of sheets, respectively.
