Abstract (en)
[origin: JPH04288697A] PURPOSE: To optically inspect a document in at least two spectrum areas with low costs without using a filter by providing at least one light inducing mechanism equipped with a fluorescent material. CONSTITUTION: A fluorescent material 3 is made of a plastic material on which fluorescent coloring agent is uniformly diffused. A light from a fluorescent tube 4 arranged at the side part of a board 3 is spread into the board 3, and absorbed by the coloring agent. Then, fluorescence with long wave length is emitted from the absorbed light. A second illuminating means 5 constituted of a light emitting diode is arranged at the very upper part of an entrance edge 7 of the board 3. The light of two spectrum sources is separated from the board 3 at an exist edge 9 by full reflection in the board 3, and a bank bill 1 is illuminated. The light diffused and reflected from the bank bill 1 is detected by detectors 13 and 14. Also, the light transmitted through the bank bill 1 is detected by a detector 15. A switching adjusting device which adjusts on/off and brightness is connected with the fluorescent tube 4 and a light emitting diode 5.
