Stationary platen type multicolor original reading device

Claim 2

A stationary platen type multicolor reading device comprising: a platen on which an original is placed; an illuminating light source section for periodically and selectively outputting monochromatic illuminating light of different hues; light guides having light input ends confronting said illuminating light source section and light output ends confronting a reading section of said platen; a photo-electric reading element for receiving that light emitted from said output ends of said light guides which is reflected from said original on said platen; said light output ends of said light guides and said photo-electric reading element being mounted on a scanner wherein said scanner is movable incrementaliy with respect to said platen; and means for triggering said photo-electric reading element in synchronization with the period selection of said illuminating light to output as electrical signals the images of an illuminated portion of said original.

Claim 3

A device as claimed in claim 1, said light guides comprising optical fibers, said fibers being bundled at the input ends thereof, the output ends thereof being substantially linearly aligned at said reading section.

Claim 4

A device as claimed in claim 2, the length of said aligned output ends being substantially equal to the maximum permissible width of an original.

Claim 5

A device as claimed in claim 1, further including an image forming optical system for focusing said reflected light on said photoelectric reading element.

Claim 6

A device as claimed in claim 1, said illuminating light source section comprising a high intensity light source, and a plurality of filters selectively positioned between said light source and said light input ends of said light guides.

Claim 7

A device as claimed in claim 1, including means for incrementally moving said scanner by one scanning line in an auxiliary scanning direction in synchronization with said periodic selection of said illuminating light.

Claim 8

A device as claimed in claim 6, said scanner being moved after said portion of said original is separately illuminated by all of said different hues.

Claim 9

A device as claimed in claim 4, said illuminating light source section being fixedly secured independently of said scanner.

Claim 10

A device as claimed in claim 4, said illuminating light source section being movably mounted independently of said scanner.

Claim 11

A stationary platen type multicolor reading device, comprising: an platen on which an original is placed; an illuminating light source section for periodically and selectively outputting monochromatic illuminating light of different hues; light guides arranged in the form of a sector, said light guides having light input ends bundled together to confront said illuminating light source section and light output ends substantially linearly aligned for a distance substantially equal to the maximum width of an original, said light output ends confronting a reading section of said platen; a photo-electric reading element; an image forming optical system for focusing, on said photo-electric reading element, that light which is emitted from said output ends of said light guides and is reflected from said original on said platen; means for triggering said photo-electric reading element in synchronization with the periodic selection of said differently hued illuminating light to output as electrical signals the images of said original as illuminated by said illuminating light of a given hue; a scanner mounting said light output ends of said light guides, said image forming optical system and said photo-electric reading element; means for incrementally moving said scanner intermittently by one auxiliary scanning line in synchronization with the period of the selection of said different hues; and means for driving said illuminating light source section independently of said scanner.

Claim 12

A stationary platen type multicolor reading device, comprising: an platen on which an original is placed; an illuminating light source section for periodically and selectively outputting monochromatic illuminating light of different hues; light guides arranged in the form of a sector, said light guides having light input ends bundled together to confront said illuminating light source section and light output ends substantially linearly aligned for a distance substantially equal to the maximum width of an original, said light output ends confronting a reading section of said platen; a photo-electric reading element; an image forming optical system for focusing, on said photo-electric reading element, that light which is emitted from said output ends of said light guides and is reflected from said original on said platen; means for triggering said photo-electric reading element in synchronization with the periodic selection of said differently hued illuminating light to output as electrical signals the images of said original as illuminated by said illuminating light of a given hue; a scanner mounting said light output ends of said light guides, said image forming optical system and said photo-electric reading element; means for incrementally moving said scanner intermittently by one auxiliary scanning line in synchronization with the period of the selection of said different hues; and means for driving said illuminating light source section independently of said scanner.
