Abstract
An apparatus for discriminating the genuineness of a security mark is provided having a first light detecting element for detecting a light emitted from a luminescent ink of the security mark placed in a specified environment and a second light detecting element for detecting a reflected light from a non-luminescent ink of the security mark. The first and second light detecting elements detect the light from the same location of a bank note. A third light detecting element detects the light intensity of a light emitted from a monitor mark that can be compared with a preset reference light intensity to calculate a deviation from the reference light intensity. The output of the first light detecting element can be converted into a corrected output value corresponding to the calculated deviation. The genuineness of the bank note can be discriminated based on the corrected output value.
