Abstract
A sheet discriminating apparatus includes a light source for emitting light toward a sheet, a spectrophotometer for receiving light emitted from the light source and reflected by a non-printed surface portion of the sheet and generating spectral data, a memory for storing reference data, and a discriminator for discriminating genuineness of the sheet based on the spectral data generated by the spectrophotometer and the reference data stored in the memory. According to the thus constituted sheet discriminating apparatus, it is possible to accurately discriminate the genuineness of a sheet, particularly a bill or security certificate.
