Abstract

Provided are a sheet recognition unit, a sheet handling device, a sheet recognition method, and a sheet recognition program capable of discriminating various photoluminescent inks and reducing a time required for the arithmetic processing. A sheet recognition unit that recognizes a sheet on which a photoluminescent ink is printed includes a light source capable of emitting at least excitation light, a light receiving unit including a plurality of light receiving elements, a storage unit that stores a coefficient based on reference data acquired by emitting the excitation light to a reference medium and a feature amount related to the photoluminescent ink associated with the reference data, the coefficient being calculated as a least squares solution with which an error is minimum, and an estimated value calculation unit that calculates an estimated value of the feature amount in the sheet to be recognized, using detection data acquired by the light receiving unit receiving light emitted from the sheet to be recognized, the sheet being irradiated with the excitation light from the light source, and the coefficient.
