ABSTRACT:
The disclosed apparatus is an electro-optical fingerprint copier.
The apparatus uses a camera with one or more lenses to copy the impression made by the ridges on the tips of fingers and thumbs. These impressions are useful as a means for identification since no two persons have the same pattern of ridges.
The apparatus also includes an automatic chart feeder, positioning and releaser, an automatic shutter control and lense system to position fingers. The features make possible the processing of an accurate fingerprint chart in a very short time.
