Abstract
A document (e.g. banknote) authenticating apparatus comprises a transport system () for transporting banknotes. An inspection device () is provided past which banknotes are transported by the transport system, the inspection device including a UV source () such as a LED and a UV detector () arranged to irradiate a banknote and to detect reflected UV respectively. A processor () is responsible to the reflected UV to determine the authenticity of the banknote. The inspection device () includes a reference surface () over which the banknotes are transported in use, the reference surface being exposed to UV radiation from the source () in the absence of a banknote so as to generate a reference level signal, and being oriented such that the banknotes are delivered at an acute angle to the surface whereby passage of a banknote across the surface effects a cleaning action on the surface.
