Claim 1
Independent Claim
298 words
Apparatus for optically copying to a desired scale with good resolution reproductions of small film images, comprising, in combination with A. the equivalent of a filmstrip/slide or animation stand apparatus including a reproducing camera mounted upon an upright track support for elevational adjustment and having the axis of its focally adjustable lens and its gate arranged substantially downward, and a lateral tabletop supported below the camera lens for interception of the axis of the latter thereby, of 1. means defining an in-focus, image-displaying internal chamber including a lateral bottom wall structure and an entrance upright sidewall with a top portion of said means having a large opening down through which the axis of the reproducing camera lens extends to the top face of the bottom wall structure and with the entrance wall having a beam entrance window; 2. means providing the top face of said bottom wall structure with a screen surface upon which an image bearing beam may be projected for display thereon of an in-focus image for photographic transfer upwardly into the reproducing camera; 3. means supporting a projector with the optical axis of its gate and projecting lens arranged substantially laterally and extending through the beam entrance window into said chamber; and 4. an oblique transparent mirror mounted in said chamber behind said entrance window and canted obliquely forward toward the latter so that its reflective surface is arranged at an acute angle to the bottom lateral screen surface with the beam entrance window located in this angle whereby said reflective surface receives image bearing beams from said projector and reflects them in focus downward to and upon said top face of the screen for reflection of the in-focus images back upward through said transparent mirror and the top opening for reception by said camera;

Apparatus for optically copying to a desired scale with good resolution reproductions of small film images, comprising, in combination with A. the equivalent of a filmstrip/slide or animation stand apparatus including a reproducing camera mounted upon an upright track support for elevational adjustment and having the axis of its focally adjustable lens and its gate arranged substantially downward, and a lateral tabletop supported below the camera lens for interception of the axis of the latter thereby, of 1. means defining an in-focus, image-displaying internal chamber including a lateral bottom wall structure and an entrance upright sidewall with a top portion of said means having a large opening down through which the axis of the reproducing camera lens extends to the top face of the bottom wall structure and with the entrance wall having a beam entrance window; 2. means providing the top face of said bottom wall structure with a screen surface upon which an image bearing beam may be projected for display thereon of an in-focus image for photographic transfer upwardly into the reproducing camera; 3. means supporting a projector with the optical axis of its gate and projecting lens arranged substantially laterally and extending through the beam entrance window into said chamber; and 4. an oblique transparent mirror mounted in said chamber behind said entrance window and canted obliquely forward toward the latter so that its reflective surface is arranged at an acute angle to the bottom lateral screen surface with the beam entrance window located in this angle whereby said reflective surface receives image bearing beams from said projector and reflects them in focus downward to and upon said top face of the screen for reflection of the in-focus images back upward through said transparent mirror and the top opening for reception by said camera;
Claim 3
Dependent Claim
17 words
said transparent mirror being of good optical glass and of a thickness (≦) one-eighth of an inch.
Claim 4
Dependent Claim
17 words
said transparent mirror being of good optical glass and of a thickness (≦) one-eighth of an inch.
Claim 5
Dependent Claim
23 words
The optical copying apparatus of claim 1 characterized by the thickness of said transparent mirror being about one-eighth of an inch (±3.175 mm).
Claim 6
Dependent Claim
64 words
The optical copying apparatus of claim 2 characterized by one of the internal chamber defining sidewalls having an access opening adjacent the screen surface through which an operator may reach to add to and/or subtract by masking from any composite image on the bottom surface screen selected image portions for altering the composite images that will be registered on film in said reproducing camera.
Claim 7
Dependent Claim
27 words
The optical copying apparatus of claim 1 characterized by the inner surfaces of the walls of the chamber structure except the bottom screen surface being ray absorptive.
Claim 8
Dependent Claim
22 words
The optical copying apparatus of claim 4 characterized by said inner wall surfaces except the bottom screen surface being ray absorptive black.
Claim 9
Dependent Claim
39 words
The optical copying apparatus of claim 1 characterized by said elevationally adjustable reproducing camera having associated therewith automatic means to keep its film gate in focus with respect to said screen surface in the elevational adjustment of said camera.
Claim 10
Dependent Claim
33 words
The optical copying apparatus of claim 1 characterized by the reflective coating of said transparent mirror having a ratio of rays transmission to rays reflection in the range of about 60:40 to 40:60.
