Abstract
A document-examining apparatus is provided for automatically examining the authenticity elements of secured documents. It includes a compound slide which can be moved in the X and Y directions and on which the components required to evaluate the distinguishing authenticity features are mounted. The X slide of the compound slide is mounted on a Y slide. A first group of evaluating units for evaluating diffraction elements on a document is disposed on the X slide. A second group of evaluating components, for example, for evaluating text, an IR field and/or a photographic field, may be mounted on the Y slide. In addition, a source of UV radiation may be provided for examining distinguishing fluorescence features of a document, the fluorescence being evaluated by a stationary evaluating unit or by the evaluating unit on the X slide.
