发明名称 Photoelectric apparatus for document counting and overlap detection
摘要 Electronic counting and control means are provided which are sensitive to the transmissivity of light and include feedback means for controlling the brightness of the light source to extend its life. Additionally, integrating means are provided for determining when there is an overlap of documents being handled by the counting means. Further, specific circuit arrangements are provided for insuring that an exact count is obtained even when perforated documents are being counted and there is a gap between successive documents.
