Abstract

PURPOSE:To make a fingerprint detector ultra-thin to enable it to be integrated in an IC card or a memory card etc., by providing a face-type sensor which detects a fingerprint placed in a fingerprint detection area at another boundary face. CONSTITUTION:A projector 19 for irradiating laser 17 is provided above a slot 13 for inserting a card 1. In the interior of the card 1, a graded index slab line 21 is located adjacent to a reception window 15 and a fingerprint detection area 9 at the upper face thereof and a CCD sensor 23 with a thickness of d2 at the lower surface thereof. Thicknesses d1, d2 and d3 are determined so that d3 is more than d2 and d3 is more than d1/d2. Here, d1 represents the thickness of the slab line 21 faced to the CCD sensor 23 and d3 the thickness immediate below the fingerprint detection area 9. When the total reflection light of the laser 17 is led to the fingerprint detection area 9 to work as a light source, scattering light by a fingerprint is generated and is focused on the upper face of the CCD sensor 23 located below the detection area 9. Namely, the fingerprint of a thumb 5 placed in the fingerprint detection area 9 is detected by the CCD sensor 23.
