Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
83 words
An aid for distortion-free reproduction of a curved page of an opened book, said aid comprising a body having a first surface shaped to fit the curved page of the opened book and a second opposite surface which has substantially the shape of a cylinder section, fiber optics connecting points of said first surface to points of said second surface, said first surface being fitted to said curved page and said second surface being exposed to apparatus for reproduction of said curved page.
Claim 2
Dependent Claim
83 words
An aid for distortion-free reproduction of a curved page of an opened book, said aid comprising a body having a first surface shaped to fit the curved page of the opened book and a second opposite surface which has substantially the shape of a cylinder section, fiber optics connecting points of said first surface to points of said second surface, said first surface being fitted to said curved page and said second surface being exposed to apparatus for reproduction of said curved page.
Claim 3
Dependent Claim
20 words
The aid of claim 1 whereby said second surface of substantially cylindrical shape has an infinite radius, thereby being plane.
Claim 4
Dependent Claim
32 words
The aid of claim 1 whereby said second surface of substantially cylindrical shape has the same curvature as an access window of a photocopier to be used for reproduction of said page.
Claim 5
Dependent Claim
15 words
The aid of claim 1 including means to press said page against said first surface.
Claim 6
Dependent Claim
27 words
The aid of claim 4 whereby said means consists in suction applied to said page through ducts incorporated in said body and terminating on said first surface.
Claim 7
Dependent Claim
31 words
The aid of claim 4 whereby said means comprise a substrate inserted into said book so that said page is sandwiched between said substrate and said first surface of said body.
Claim 8
Dependent Claim
23 words
The aid of claim 6 whereby said substrate is shaped to conform substantially to the shape of said first surface of said body.
Claim 9
Dependent Claim
15 words
The aid of claim 6 including means to charge said substrate electrically against said body.
Claim 10
Dependent Claim
14 words
The aid of claim 6 whereby said substrate is made of a ferromagnetic material.
Claim 11
Dependent Claim
11 words
The aid of claim 7 whereby said substrate contains suction ducts.
