Abstract
Abstract A multi-mode image recording apparatus which can record on a common photo-sensitive sheet either an analog color image produced by reflecting white light off an original or a digital color image produced by modulating one or more infrared lasers according to an electrical signal. The photo-sensitive sheet is sensitive to three bands of visible radiation and to at least one band of infrared and is developed by pressure to three visible colors.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
An image recording apparatus, comprising: a photosensitive material developable into three colors; an analog exposure unit comprising a source of visible light directed at an original and a first set of optics for directing light reflected from said original to said photosensitive material; and a digital exposure unit comprising first and second respective light sources, individually modulated by first and second image signals, and respectively emitting modulated first and second beams of infrared radiation in first and second wavelength bands and a second set of optics for combining and directing said first and second beams to said photosensitive material, wherein said photosensitive material is developable into first and second colors in response to application of said first and second wavelength bands of said first and second beams, respectively, and wherein said light reflected from said original and said first beam simultaneously irradiate said photosensitive material.
Claim 2
Dependent Claim
145 words
An image recording apparatus, comprising: a photosensitive material developable into three colors; an analog exposure unit comprising a source of visible light directed at an original and a first set of optics for directing light reflected from said original to said photosensitive material; and a digital exposure unit comprising first and second respective light sources, individually modulated by first and second image signals, and respectively emitting modulated first and second beams of infrared radiation in first and second wavelength bands and a second set of optics for combining and directing said first and second beams to said photosensitive material, wherein said photosensitive material is developable into first and second colors in response to application of said first and second wavelength bands of said first and second beams, respectively, and wherein said light reflected from said original and said first beam simultaneously irradiate said photosensitive material.
Claim 3
Dependent Claim
78 words
An image recording apparatus as recited in claim 1, wherein said digital exposure unit further comprises a third light source modulated by a third image signal and emitting a modulated third beam of radiation in a third wavelength band and wherein second set of optics includes means for combining said first, second and third beams, wherein said photosensitive material is developable into a third color in response to application of said third wavelength band of said third beam.
Claim 4
Dependent Claim
36 words
An image recording apparatus as recited in claim 2, further comprising a movable reflector to alternately direct to said photosensitive material either said light reflected from said original or said combined first, second and third beams.
Claim 5
Dependent Claim
18 words
An image recording apparatus as recited in claim 3, wherein said second wavelength band comprises a visible band.
Claim 6
Dependent Claim
33 words
An image recording apparatus as recited in claim 1, further comprising means for pressing said photo-sensitive material to thereby develop an image exposed therein by either of said analog and digital exposure units.
Claim 7
Dependent Claim
41 words
An image recording apparatus as recited in claim 5, wherein said photo-sensitive material is photo-sensitive to three wavelength bands of visible light to produce corresponding colors of said developed image and is photo-sensitive to said first wavelength band of infrared radiation.
Claim 8
Dependent Claim
23 words
An image recording apparatus as recited in claim 6, wherein said three colors of said developable photosensitive material are cyan, magenta and yellow.
Claim 9
Dependent Claim
34 words
An image recording apparatus as recited in claim 1, further comprising a movable reflector to alternately direct to said photosensitive material said light reflected from said original or said first beam of infrared radiation.
