ABSTRACT:
A personal identification device has: a light source portion that emits infrared light with a first wavelength at the time of reading a vein pattern, and emits infrared light with a second wavelength longer than the first wavelength at the time of reading a fingerprint pattern; a light receiving sensor portion that detects a component of the infrared light reflected from a fingertip after being shone thereon from the light source portion; an amplifying portion that amplifies a detection signal obtained by the light receiving sensor portion; an A/D converting portion that converts an analog signal obtained by the amplifying portion into a digital signal; a data distributing portion that distributes the digital signal obtained by the A/D converting portion into two groups of data, of which one is vein pattern data and the other is fingerprint pattern data; and a processing portion that verifies the identity of a person based on the vein pattern data and the fingerprint pattern data distributed by the data distributing portion.
