20120092648 | OPTICAL SYSTEM AND SENSOR FOR CHECKING VALUE DOCUMENTS HAVING SUCH AN OPTICAL SYSTEM - An optical system having a plane anisotropic retroreflector portion which specularly reflects radiation components in a first plane of incidence, but retroreflects radiation components in a second plane of incidence, a first imaging portion which produces on the retroreflector portion a line-shaped intermediate image of an object point in an object plane in a specified position relative to the system, the image extending along a line in the second plane of incidence, and a second imaging portion by means of which the line-shaped intermediate image is imaged into an image point. | 04-19-2012 |
20110199649 | METHOD AND DEVICE FOR PROCESSING VALUE DOCUMENTS - The invention relates to an apparatus and a method for processing value documents. A value document is input to the input opening of an apparatus for value-document processing and transported using a transport system of the apparatus to an image sensor which senses a partial image of the value document. A contour of the front partial area is ascertained from the sensed partial image and checked. If the check of the contour of the front partial area yields a fault, the value document is rejected. Faulty or faultily transported value documents can thus be recognized and transported back to the input opening at a very early time. | 08-18-2011 |
