Abstract
Abstract Apparatus for copying various types of information such as words, phrases, sentences, symbols or the like. This complete apparatus, which is adapted to copy selected portions of a complete text, is characterized by the incorporation of a shutter mechanism, which forms an integral part of a carriage transport structure, which carriage transport supports a lens system and lamp therefor, and a charging unit. The shutter is biased in one direction by means of a spring which serves to drive the carriage in the exposing mode. Another part of the shutter is so coupled to manually operable mechanism as to be capable of returning the carriage to its initial position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
105 words
Copying apparatus comprising: casing structure; means in said casing structure for supporting a photosensitive surface; means for selectively exposing said photosensitive surface to an object to be copied to thereby prInt a latent image on said surface; carriage means supporting said exposing means for movement relative to said surface and said object between first and second positions; means for selectively moving said carriage from said first position to said second position to thereby form an image on said photosensitive surface; and means including said photosensitive surface for manually returning said carriage to said first position after said latent image has been formed on said surface.
Claim 2
Dependent Claim
105 words
Copying apparatus comprising: casing structure; means in said casing structure for supporting a photosensitive surface; means for selectively exposing said photosensitive surface to an object to be copied to thereby prInt a latent image on said surface; carriage means supporting said exposing means for movement relative to said surface and said object between first and second positions; means for selectively moving said carriage from said first position to said second position to thereby form an image on said photosensitive surface; and means including said photosensitive surface for manually returning said carriage to said first position after said latent image has been formed on said surface.
Claim 3
Dependent Claim
28 words
Structure as specified in claim 1 including means for developing said latent image on said charge-retentive surface simultaneously with the return of said carriage to said first position.
Claim 4
Dependent Claim
26 words
Structure as specified in claim 1 including record paper to which a developed image is transferred simultaneously with movement of said carriage to said first position.
Claim 5
Dependent Claim
115 words
Copying apparatus comprising: casing structure; means in said casing structure for supporting a charge-retentive surface; means for selectively exposing said charge-retentive surface to an object to be copied to thereby print a latent image on said surface; means for charging said charge-retentive surface; carriage means supporting said exposing means and such charging means for movement relative to said surface and said object in first and second position; means for selectively moving said carriage from said first position to said second position to thereby form an image on said charge-retentive surface; and means including said charge-retentive surface for manually returning said carriage to said first position after said latent image has been formed on said surface.
Claim 6
Dependent Claim
115 words
Copying apparatus comprising: casing structure; means in said casing structure for supporting a charge-retentive surface; means for selectively exposing said charge-retentive surface to an object to be copied to thereby print a latent image on said surface; means for charging said charge-retentive surface; carriage means supporting said exposing means and such charging means for movement relative to said surface and said object in first and second position; means for selectively moving said carriage from said first position to said second position to thereby form an image on said charge-retentive surface; and means including said charge-retentive surface for manually returning said carriage to said first position after said latent image has been formed on said surface.
Claim 7
Dependent Claim
39 words
Structure as specified in claim 4 wherein said means for selectively moving said carriage from said first position to said second position comprises a spring which is wound by said means for returning said carriage to said first position.
