Title (EN) APPARATUS FOR DETECTING THE PASSAGE OF MULTIPLE DOCUMENTS
(FR) APPAREIL DE DETECTION DU PASSAGE DE PLUSIEURS DOCUMENTS
Abstract: front page image
(EN)An apparatus for detecting the passage of multiple documents (10) in a transport system, including a pair of rollers (20, 22) between which said documents (10) are arranged to pass and which are displaceable by an extend dependent on the thickness of one document or multiple documents simultaneously passing therebetween. This displacement is measured by the movement of a graded density translucent member (34) between the photodiode (46) and sensor (40) of a detector (36). Electronic circuitry associated with the detector (36) indicates the presence of a record member (10) between the rollers (20, 22), and also the presence of multiple record members (10). The graded density of the member (34) allows the circuitry to detect only the displacement from the static position of the rollers (20, 22) eliminating the necessity for adjustment due to wear, temperature, and other mechanical factors.
(FR)Appareil de detection du passage de plusieurs documents (10) dans un systeme de transport, comprenant une paire de rouleaux (20, 22) entre lesquels ces documents (10) sont disposes pour passer, et qui peuvent etre deplaces d'une distance dependant de l'epaisseur d'un document ou de plusieurs documents passant simultanement entre ces rouleaux. Ce deplacement est mesure par le mouvement d'un organe translucide a densite graduee (34) entre la photodiode (46) et un capteur (40) d'un detecteur (36). Un circuit electronique associe au detecteur (36) indique la presence d'un organe d'enregistrement (10) entre les rouleaux (20, 22), et egalement la presence de plusieurs organes d'enregistrement (10). La densite graduee de l'organe (34) permet au circuit de detecter seulement le deplacement a partir de la position statique des rouleaux (20, 22) eliminant le besoin d'ajustement du a l'usure, la temperature, et autres facteurs mecaniques.
