Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
144 words
An integrated array of cooperating optical imaging components adapted to be used with prescribed transport imaging means disposed along a prescribed transport-platform, this array comprising: a pair of like optical-housing units offset along said path, each unit enclosing and positioning a cooperating array of optical illumination-imaging components, each unit being adapted to be mounted on said platform; a heat generating Spectral Radiation Source means arranged and adapted to be attached to said platform and optically-coupled with each said unit; and Heat-Dissipation means disposed in infra-red receiving relation with said Source means, and adapted to trap and dissipate infrared radiation, this Dissipation means being mounted on said platform so as to isolate said optical components from said dissipation means and radiation source means, thermally and optically; each unit being adapted to direct at least one pair of illumination-beams onto passing documents from equal, opposite angles.
Claim 2
Dependent Claim
144 words
An integrated array of cooperating optical imaging components adapted to be used with prescribed transport imaging means disposed along a prescribed transport-platform, this array comprising: a pair of like optical-housing units offset along said path, each unit enclosing and positioning a cooperating array of optical illumination-imaging components, each unit being adapted to be mounted on said platform; a heat generating Spectral Radiation Source means arranged and adapted to be attached to said platform and optically-coupled with each said unit; and Heat-Dissipation means disposed in infra-red receiving relation with said Source means, and adapted to trap and dissipate infrared radiation, this Dissipation means being mounted on said platform so as to isolate said optical components from said dissipation means and radiation source means, thermally and optically; each unit being adapted to direct at least one pair of illumination-beams onto passing documents from equal, opposite angles.
Claim 3
Dependent Claim
46 words
The array according to claim 1 wherein said Source means comprises a single high-intensity lamp emitting a beam of spectral radiation; and wherein said optical components are disposed in a pair of like illumination arrays, one for illuminating each side of documents transported across said platform.
Claim 4
Dependent Claim
16 words
The array of claim 2 wherein said array includes camera means and photopic filter means therefor.
Claim 5
Dependent Claim
49 words
The array according to claim 3 wherein a pair of like camera means are also carried on each said unit, each with an array of imaging-path optical components adapted for conducting illumination from a respective illumination array; and for correcting the image-spectrum to approximate that of the human eye.
Claim 6
Dependent Claim
73 words
A document imaging apparatus including transport means disposed operatively adjacent two sites on a transport platform with associated document-illumination and document-imaging means, said illumination means including lamp means and associated heat-dissipation means mounted below said platform; said imaging means including camera means and optical coupling means mounted above said platform; said coupling means being adapted to couple said sites with said lamp means and with said camera means, and including photopic filter means.
Claim 7
Dependent Claim
73 words
A document imaging apparatus including transport means disposed operatively adjacent two sites on a transport platform with associated document-illumination and document-imaging means, said illumination means including lamp means and associated heat-dissipation means mounted below said platform; said imaging means including camera means and optical coupling means mounted above said platform; said coupling means being adapted to couple said sites with said lamp means and with said camera means, and including photopic filter means.
Claim 8
Dependent Claim
44 words
The array according to claim 5 where said optical coupling means effect a first-split of the illumination beam, and then effect a second-split, whereby to provide a pair of like, oblique, symmetrical beams, one on each side of passing document, at each said site.
Claim 9
Dependent Claim
45 words
The array according to claim 6 wherein the lamp means comprises a single high-intensity lamp emitting a beam of spectral radiation; and wherein optical components are disposed in a pair of like illumination arrays, one for illuminating each side of documents transported across said platform.
Claim 10
Dependent Claim
33 words
The array according to claim 7 where a pair of like camera means are carried atop said platform along with related imaging-path optical components, and said lamp means is disposed under the platform.
Claim 11
Dependent Claim

The array according to claim 5 wherein the transport platform mounts camera means to be isolated thermally and optically from said lamp means.
Claim 12
Dependent Claim
18 words
The array of claim 11 including an optic-casting housing beam-splitter means and mirror means mounted on said platform.
Claim 13
Dependent Claim
24 words
The array of claim 5 wherein said lamp means is mounted on a sub-casting LC which, in turn, is affixed removably on said platform.
Claim 14
Dependent Claim
63 words
The array of claim 5, as mounted upon a machine casting and said platform is a document transport surface and is made to be removably affixed to said casting or, alternatively, to be pivoted upward away from said casting to accommodate access thereto; and wherein said casting is also mounted on rail means whereby to be selectively rolled away from said transport platform.
