Abstract
The device for examining securities, especially bank notes, includes a transport facility for conveying securities along a transport path and a recognition facility arranged on the transport path. The recognition facility has two integrated optical modules arranged alongside each other for scanning securities in two different wavelength ranges. The optical modules are arranged with their long axes basically parallel to each other, and at the same time slightly tipped toward each other. The optical module extends over an entire breadth of the transport path. It includes several light sources arranged at regular intervals, a larger number of optical imagining elements and several optical detectors, whereby the security is passed by a transparent front panel of the module.
