Abstract
Abstract Optical print apparatus for use with film having individual frame numbers exposed for each camera exposure. During printing from the negative a secondary optical system intercepts the frame number, magnifies it and projects it for printing on the edge of the print paper.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
198 words
In photographic printing apparatus for film having an individual film frame number adjacent each film frame and which apparatus includes a film holder, a print plane, a printing lens positioned therebetween and means for selectively exposing a film frame in said holder for projection of an image thereof through said lens onto a predetermined area of said print plane, the improvement comprising: secondary optical projection means, positioned between said printing lens and the print plane, for intercepting the projection of a film frame number from said printing lens and projecting it to an edge of said predetermined area in the print plane at a desired orientation relative to the projection of a film frame and at a lower factor of magnification therefrom; said second optical projection means comprising a coherent fiber optic bundle having its first end adjacent said edge of said predetermined area of said print plane and its second end facing said printing lens, a collecting lens positioned between said printing lens and the second end of said fiber optic bundle, and a relay lens positioned between the first end of said fiber optic bundle and said edge of said predetermined area of said print plane.
Claim 2
Dependent Claim
198 words
In photographic printing apparatus for film having an individual film frame number adjacent each film frame and which apparatus includes a film holder, a print plane, a printing lens positioned therebetween and means for selectively exposing a film frame in said holder for projection of an image thereof through said lens onto a predetermined area of said print plane, the improvement comprising: secondary optical projection means, positioned between said printing lens and the print plane, for intercepting the projection of a film frame number from said printing lens and projecting it to an edge of said predetermined area in the print plane at a desired orientation relative to the projection of a film frame and at a lower factor of magnification therefrom; said second optical projection means comprising a coherent fiber optic bundle having its first end adjacent said edge of said predetermined area of said print plane and its second end facing said printing lens, a collecting lens positioned between said printing lens and the second end of said fiber optic bundle, and a relay lens positioned between the first end of said fiber optic bundle and said edge of said predetermined area of said print plane.
Claim 3
Dependent Claim
37 words
The invention according to claim 1 wherein said fiber optic bundle is twisted along a longitudinal axis to provide a desired orientation of a frame number as it is projected on the edge of said print plane.
Claim 4
Dependent Claim
245 words
In photographic printing apparatus for film having an individual film frame number adjacent each film frame and which apparatus includes a film holder, a print plane, a printing lens positioned therebetween and means for selectively exposing a film frame in said holder for projection of an image thereof through said lens onto a predetermined area of said print plane, the improvement comprising: secondary optical projection means, positioned between said printing lens and the print plane, for intercepting the projection of a film frame number from said printing lens and projecting it to an edge of said predetermined area in the print plane at a desired orientation relative to the Projection of a film frame and at a lower factor of magnification therefrom; said second optical projection means comprising first and second reflecting mirrors positioned between said printing lens and said printing plane such that said first mirror intercepts said frame number and directs it toward said second mirror and said second mirror directs it toward the desired edge of said predetermined area of said print plane, and an imaging lens positioned between said second mirror and said edge of said predetermined area of said print plane to image said frame number thereon, and first and second inversion prisms positioned between said second mirror and said imaging lens, said first and second inversion prisms being adjusted to establish the desired orientation of said frame number on said edge of said predetermined area of said print plane.
Claim 5
