Card type device capable of reading fingerprint and fingerprint identification system
First Claim
1. A card type device comprising:
- a card type housing;
a transparent cylindrical-shaped roller provided at an edge plane of said card type housing, the outer peripheral plane of which is projected from said edge plane;
a light source provided in an internal hollow portion of said roller, for irradiating a finger which abuts against the outer peripheral plane of said roller;
a one-dimensional image sensor provided in said internal hollow portion of said roller, for acquiring one-dimensional fingerprint image data of the finger which abuts against the outer peripheral plane of said roller;
a SELFOC lens array provided in said internal hollow portion of said roller, for focusing a one-dimensional image of the finger which abuts against the outer peripheral plane of said roller onto said one-dimensional image sensor; and
a holder for holding thereon said light source, said one-dimensional image sensor, and said SELFOC lens array, which is fixed to said card type housing in such a manner that even when said roller is rotated, said holder is not rotated.

Abstract
A card type device is mounted on a card slot of an electronic appliance. A transparent cylindrical-shaped roller is provided at an edge portion of a housing such that an outer peripheral plane of the roller is projected from the edge portion. A one-dimensional image sensor is provided inside the roller, which acquires one-dimensional fingerprint data of a finger of a user, and this fingerabuts against the outer peripheral plane of the roller. Since the finger abutting against the outer peripheral plane of the roller is moved, the roller is rotated, so that one-dimensional fingerprint data which are continuously acquired by the one-dimensional image sensor are synthesized with each other to produce fingerprint data as a two-dimensional image. The synthesized fingerprint data is transmitted to the electronic appliance which carries out fingerprint identification.
