Abstract
A fingerprint recognition device, applicable to retrieving a fingerprint image, includes a light guiding plate, a finger plate, an imaging piece, and at least one light source. The light guiding plate has a first surface and a second surface opposite to each other and a sidewall surface connected between the first surface and the second surface. The finger plate is adjacent to the first surface of the light guiding plate. The imaging piece is adjacent to the second surface of the light guiding plate, and the light source is adjacent to the sidewall surface of the light guiding plate. The light source emits a light towards the sidewall surface and the light enters the light guiding plate. The light guided by the light guiding plate is emitted out of the first surface, and the imaging piece retrieves the fingerprint image on the finger plate.
