摘要

Provided is a skin pattern image collection device wherein it is possible to obtain a fingerprint image which has a high contrast and few distortions. The skin pattern image collection device is provided with a contact means in which two transparent sheets, which are formed with a plurality of grooves of the same shape arranged in a single direction on one surface, are overlapped, and an imaging means which is disposed so as to receive the light from the surface, on which the grooves are formed, of the contact means, wherein the contact means refracts the light, which is outputted from the transparent sheet that is farther from the imaging means of the two transparent sheets disposed on the contact means, in a roughly normal direction by means of the transparent sheet that is closer to the imaging means, thereby collecting the pattern of skin which is in contact with the transparent sheet that is farther from the imaging means.
