Claims (2)

1. Vorrichtung zur Detektion einer Flachgutkante, z. B. einer Papierbogen-Kante, mit einer Sammellinse (4), einer in der optischen Achse (20) der Sammellinse (4) angeordneten, im wesentlichen punktförmigen Lichtquelle (1), einer Strahlteiler-Einheit (3), die eine Transmissions-Eingangsöffnung (8), eine Reflexions-Ausgangsöffnung (10) und eine Transmissions-Ausgangs- und Reflexions-Eingangsöffnung (9) umfaßt, und einem optischen Sensorelement (2), an das eine Komparator-Einheit (19) angeschlossen ist, wobei die im wesentlichen punktförmige Lichtquelle (1) im Abstand der doppelten Brennweite (2f) der Sammellinse (4) von dieser entfernt und die Strahlteiler-Einheit (3) zwischen der im wesentlichen punktförmigen Lichtquelle (1) und der Sammellinse (4) angeordnet ist, und wobei das optische Sensorelement (2) auf die Reflexions-Ausgangsöffnung (10) der Strahlteiler-Einheit (3) gerichtet ist, dadurch gekennzeichnet, daß auf der der Lichtquelle (1) gegenüberliegenden Seite der Sammellinse (4) im Abstand der doppelten Brennweite (2f) von der Sammellinse (4) entfernt ein Bereich (32) zur Detektion der Flachgutkante (31) ausgebildet ist, wobei beim Auftreffen des im Detektionsbereich (32) fokussierten Lichtstrahls der im wesentlichen punktförmigen Lichtquelle (1) auf eine Kante einer mit einem Normalabstand in der Größe der doppelten Brennweite (2f) von der Sammellinse (4) entfernten Flachgutoberfläche die von der Flachgutkante reflektierte Lichtintensität ein Sensorsignal hervorruft, das einen vorbestimmbaren Schwellwert der Komparator-Einheit (19) überschreitet.1. Device for the detection of a flat goods edge, for. B. a paper sheet edge, with a converging lens (4), one in the optical axis (20) of the converging lens (4) arranged, essentially point-shaped light source (1), a beam splitter unit (3), which has a transmission input opening (8), a reflection output opening (10) and a transmission output and reflection input opening (9), and an optical sensor element (2) to which a comparator unit (19) is connected, the substantially punctiform light source (1) at a distance of twice the focal length (2f) of the converging lens (4) from this and the beam splitter unit (3) is arranged between the essentially punctiform light source (1) and the converging lens (4), and wherein Optical sensor element (2) is directed onto the reflection output opening (10) of the beam splitter unit (3), characterized in that on the side of the converging lens (4) opposite the light source (1) at a distance of twice the focal length (2f) v on the converging lens (4) there is an area (32) for the detection of the flat material edge (31), whereby when the light beam of the essentially punctiform light source (1) focused in the detection area (32) strikes an edge of a surface with a normal distance in the Size of twice the focal length (2f) from the flat lens surface away from the converging lens (4), the light intensity reflected from the flat goods edge causes a sensor signal that exceeds a predeterminable threshold value of the comparator unit (19). 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die im wesentlichen punktförmige Lichtquelle durch eine Laser-Diode (1) und das optische Sensorelement durch einen Photo-Transistor (2) oder eine Photo-Diode gebildet sind.2. Device according to claim 1, characterized in that the substantially punctiform light source through a laser diode (1) and through the optical sensor element a photo transistor (2) or a photo diode are formed.
