ABSTRACT:
The disclosed apparatus is an electro-optical fingerprint photocopier to copy fingerprints of a person.
This apparatus uses a camera with one or more lenses to photocopy the impression made by the ridges on the tips of the fingers and thumbs. These impressions are useful as means for identification since no two persons have the same ridges pattern.
This apparatus also includes an automatic chart feeder, positioning and releaser, an automatic shutter control and concave-convex lenses to position the fingers. The features make possible the processing of an accurate fingerprint chart in a very short time.
The apparatus shall be especially used in the identification of persons, in the military, naval, police and immigration services, and in various commercial transactions. Also, shall be used by schools and other learning institutions for the proper identification of students.
