Abstract
Abstract The present invention is a novel book scanner that employs 2-dimensional array detectors attached, either rigidly or rotatably, at a common edge and disposed in a wedge shaped manner. The opposite edges of the arrays are housed in a base portion. The base portion additionally supports backlight to provide the necessary illumination of the book pages and the read-out electronics which output the image data stored in the detectors to other processing units that may use such data.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
A scanner for capturing the image of pages in a book, said scanner comprising: a substantially wedge shaped member having an apex and a pair of angularly splayed surfaces extending from said apex, upon which a partially opened book may be supported with its spine adjacent said apex and its opposing pages adjacent said surfaces; a 2-dimensional detector located upon each of said surfaces for collecting image data; a light source for illuminating the opposing pages through said detector; and read-out circuitry connected to said detector for obtaining image data collected by said detector.
Claim 2
Dependent Claim
94 words
A scanner for capturing the image of pages in a book, said scanner comprising: a substantially wedge shaped member having an apex and a pair of angularly splayed surfaces extending from said apex, upon which a partially opened book may be supported with its spine adjacent said apex and its opposing pages adjacent said surfaces; a 2-dimensional detector located upon each of said surfaces for collecting image data; a light source for illuminating the opposing pages through said detector; and read-out circuitry connected to said detector for obtaining image data collected by said detector.
Claim 3
Dependent Claim
81 words
A scanner for capturing the image of pages in a book, said scanner comprising: a first and a second 2-dimensional detector, each detector having a surface, a first edge and a second edge opposite said first edge, said detectors coupled at said first edges such that said surfaces are disposed in a substantial wedge shape; a light source for illuminating the opposing pages through said detector; and read-out circuitry connected to said detector for obtaining image data collected by said detector.
Claim 4
Dependent Claim
81 words
A scanner for capturing the image of pages in a book, said scanner comprising: a first and a second 2-dimensional detector, each detector having a surface, a first edge and a second edge opposite said first edge, said detectors coupled at said first edges such that said surfaces are disposed in a substantial wedge shape; a light source for illuminating the opposing pages through said detector; and read-out circuitry connected to said detector for obtaining image data collected by said detector.
Claim 5
Dependent Claim
20 words
A scanner as recited in claim 2 wherein said first and second detectors are rigidly coupled at said first edges.
Claim 6
Dependent Claim
16 words
A scanner as recited in claim 2 wherein said first and second detectors are rotatably coupled.
Claim 7
Dependent Claim
24 words
A scanner as recited in claim 2 wherein said first and second detector are electrically coupled such that there is one logical scanning surface.
Claim 8
Dependent Claim
33 words
A scanner as recited in claim 5 wherein the first and second detectors, each detector having grid lines, are coupled such that each pair of corresponding grid lines is connected by a connector.
Claim 9
Dependent Claim
35 words
A scanner as recited in claim 5 wherein the first and second detectors, each detector having grid lines, are coupled such that each grid line from each said detector is connected to an interconnect circuit.
