摘要

A fingerprint identification apparatus includes an illuminating member, a light conducting panel and a light concentration lens formed into a single body for easily assembling and preventing noise produced by the light conducting panel. Also, an ultra-luminance chip coated with a diffuser compound, and a rheostat installed to identify a fingerprint image formed by an imaging lens accurately and clearly enhances the reliability of the fingerprint identification apparatus.
