Abstract
Abstract Optical copying apparatus wherein a transparent support for a positive or negative original is movable back and forth in or counter to the direction of travel of the copy. The light source is stationary so that it illuminates successive increments of the original on the moving support. The optical system comprises two axially spaced objective lenses and an image inverting optical device (such as an Abbe prism) which is located between the lenses and is turnable through 90* about the optical axis to assume a first position when the support travels in one direction of a second position when the support travels in the opposite direction. The support is reciprocated by the drive for the copy, and such drive also changes the position of the optical device when the support changes the direction of its movement.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
112 words
Optical copying apparatus comprising support means for moving originals in a first direction and in a second direction counter to said first direction, an objective system for focusing the image of the original moving with said support means onto a copy which travels in substantial parallelism with one of said directions; a source of light for illuminating successive increments of the original on said support means; and an image inverting optical device mounted between said support means and the traveling copy for rotation about the optical axis of said objective system between first and second positions which it respectively assumes when said support means respectively moves in said first and second directions.
Claim 2
Dependent Claim
112 words
Optical copying apparatus comprising support means for moving originals in a first direction and in a second direction counter to said first direction, an objective system for focusing the image of the original moving with said support means onto a copy which travels in substantial parallelism with one of said directions; a source of light for illuminating successive increments of the original on said support means; and an image inverting optical device mounted between said support means and the traveling copy for rotation about the optical axis of said objective system between first and second positions which it respectively assumes when said support means respectively moves in said first and second directions.
Claim 3
Dependent Claim
35 words
Optical copying apparatus as defined in claim 1, wherein said light source and said objective system are disposed at the opposite sides of said support means and wherein said support means consists of light-transmitting material.
Claim 4
Dependent Claim
20 words
Optical copying apparatus as defined in claim 1, wherein said optical device is rotatable back and forth through 90* degrees.
Claim 5
Dependent Claim
25 words
Optical copying apparatus as defined in claim 1, wherein said support means and the copy are movable in substantially horizontal planes located at different levels.
Claim 6
Dependent Claim
36 words
Optical copying apparatus as defined in claim 1, further comprising drive means for transporting the copy in parallelism with said one direction and for moving said support means in one of said first and second directions.
Claim 7
Dependent Claim
36 words
Optical copying apparatus as defined in claim 5, wherein said drive means comprises means for changing the angular position of said optical device in response to changes in the direction of movement of said support means.
Claim 8
Dependent Claim
38 words
Optical copying apparatus as defined in claim 1, wherein said optical device is respectively located in planes which are parallel with and normal to the direction of movement of the copy in said first and second positions thereof.
Claim 9
Dependent Claim
27 words
Optical copying apparatus as defined in claim 1, wherein said objective system comprises a pair of lenses and wherein said optical device is located between said lenses.
Claim 10
Dependent Claim
33 words
Optical copying apparatus as defined in claim 1, wherein said light source comprises a plurality of elongated fluorescent tubes extending substantially at right angles to the directions of movement of said support means.
