Abstract
Abstract An assembly for the introduction of fingerprint data in an identification system including an input surface to lie on an optical axis and a strip of light transmitting film carried on suitable wind-out and wind-in reels to provide a fresh surface when moved incrementally across the input surface. Assembly also may be moved in limited rotation for alignment.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
In an identification system using fingerprints as input data in an optical system, a fingerprint input station assembly comprising: a. a transparent element to be located on an optical axis in an identification system serving as an input surface for a fingerprint, b. means to mount said element comprising a support bracket having an extending member, and c. means carrying said element supported on said member for rotation in a limited angular movement relative to an axis passing through said element.
Claim 2
Dependent Claim
81 words
In an identification system using fingerprints as input data in an optical system, a fingerprint input station assembly comprising: a. a transparent element to be located on an optical axis in an identification system serving as an input surface for a fingerprint, b. means to mount said element comprising a support bracket having an extending member, and c. means carrying said element supported on said member for rotation in a limited angular movement relative to an axis passing through said element.
Claim 3
Dependent Claim
139 words
In an identification system using fingerprints as input data in an optical system, a fingerprint input station assembly comprising: a. a transparent element to be located on an optical axis in an identification system serving as an input surface for a fingerprint, b. a mount bar and a support bracket on said bar having a first plate extending transversely to said bar, said plate having an aperture, and c. means to mount said element to align with said aperture and to be rotatable relative to said aperture comprising a mount plate, bushing means in said plate carrying said element and having a bearing relationship with the first plate at said aperture whereby said mount plate and said element are supported on and rotatably movable relative to said first plate on an axis passing through said aperture and said element.
Claim 4
Dependent Claim
139 words
In an identification system using fingerprints as input data in an optical system, a fingerprint input station assembly comprising: a. a transparent element to be located on an optical axis in an identification system serving as an input surface for a fingerprint, b. a mount bar and a support bracket on said bar having a first plate extending transversely to said bar, said plate having an aperture, and c. means to mount said element to align with said aperture and to be rotatable relative to said aperture comprising a mount plate, bushing means in said plate carrying said element and having a bearing relationship with the first plate at said aperture whereby said mount plate and said element are supported on and rotatably movable relative to said first plate on an axis passing through said aperture and said element.
Claim 5
Dependent Claim
58 words
In a fingerprint input station assembly as defined as in claim 1, a. a film strip support means on said means supported on said member b. a film strip on said support means, and c. means to guide said film strip over said transparent element to provide a renewable surface for a fingerprint impression at said transparent element.
Claim 6
Dependent Claim
55 words
In a fingerprint input station assembly as defined in claim 2, a. a film support plate on said mount plate, b. reel-in and reel-out reels on said film support plate, and c. a film strip on said reels extending over said element to provide a renewable surface for a fingerprint impression at said transparent element.
