Fingerprint identification apparatus for enhancing identification performance by forming an illumination source and a light conducting panel in a single body

Claim 1

A fingerprint identification apparatus, comprising: a housing having an illumination source for illuminating a fingerprint by radiating light, said illumination source including, a plurality of ultra-luminance chips, a diffuser coating layer for diffusing light radiation from said plurality of ultra-luminance chips, a rheostat for maintaining a uniform brightness by controlling a resistance value to form a clear image of said fingerprint; a light conducting panel for placing said fingerprint thereon and being illuminated from the light by the light radiated from said illumination source, and a light concentration lens for concentrating the light diffused from the fingerprint; an imaging lens for forming a fingerprint image from said light totally reflected from said fingerprint placed on said light conducting panel; a CCD for converting said fingerprint image formed by said imaging lens to an electrical signal; a signal processor for analyzing and identifying said fingerprint image converted to said electrical signal by said CCD; and a sensor for detecting said light concentrated by said light concentration lens and activating said signal processor.
