Abstract
Abstract The present invention provides an imaging device and method for developing, duplicating and printing graphic media. The imaging device of the present invention is utilized in devices such as copiers, printers, game cards and the like, and comprises a substrate bearing an infrared image producing layer, a thermal image forming layer and a light source. A brief but intense flash of visible light from the light source causes latent heat properties of the infrared layer to generate heat and convert visible light into far infrared light. This far infrared light develops or marks portions of the thermal layer which are adjacent the infrared layer.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
93 words
Apparatus for reproducing an image, comprising: a light source for emitting pulses of visible light; a substrate; an image including an infrared producing layer on said substrate, an image portion of said image producing layer responsive to said light source for converting said pulses of visible light into infrared light; an image forming layer responsive to said infrared light to develop at least one portion of said image forming layer; and means in said image portion of said infrared image producing layer for forming an infrared image not visible to an unaided eye.
Claim 2
Dependent Claim
93 words
Apparatus for reproducing an image, comprising: a light source for emitting pulses of visible light; a substrate; an image including an infrared producing layer on said substrate, an image portion of said image producing layer responsive to said light source for converting said pulses of visible light into infrared light; an image forming layer responsive to said infrared light to develop at least one portion of said image forming layer; and means in said image portion of said infrared image producing layer for forming an infrared image not visible to an unaided eye.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1, wherein the image forming layer further comprises: image forming means developed by infrared light from said image portion for reproducing said image.
Claim 4
Dependent Claim
65 words
Apparatus for reproducing an image, comprising: a visible light source; an image responsive to said light source for converting said visible light into infrared light; an image forming layer responsive to said infrared light to develop at least one portion of said image forming layer; a substrate supporting said image; and layer means on said substrate covering said image for obscuring said image until developed.
Claim 5
Dependent Claim
65 words
Apparatus for reproducing an image, comprising: a visible light source; an image responsive to said light source for converting said visible light into infrared light; an image forming layer responsive to said infrared light to develop at least one portion of said image forming layer; a substrate supporting said image; and layer means on said substrate covering said image for obscuring said image until developed.
Claim 6
Dependent Claim
35 words
