Claim 9

An imaging device wherein a latent image is formed by projecting a photo-image on a photosensitive member before developing a visible image comprising a housing having a support adapted to support a manuscript thereon; a cartridge detachably mounted within said housing for supplying said photosensitive member; light exposure means provided in said housing for duplicating a photo-image of said manuscript placed on said support on said photosensitive member; conveying means for conveying said photosensitive member through said housing; and light shielding means for protecting said photosensitive member against ambient light other than the light impinged thereon by said light exposure means, while travelling through said housing.

Claim 10

The imaging device according to claim 3 which further comprises separating means for leaving said transfer member from said photosensitive member after pressurized by said pressure applying means.

Claim 11

An imaging device wherein a continuous sheet carrying thereon photosensitive microcapsules each enveloping a dye precursor therein is utilized to form a latent image thereon, and a recording medium carrying thereon a color developing agent which reacts to said dye precursor to develop color is utilized to develop a visible image thereon, which comprises; a housing having a manuscript table; first conveying means for conveying said continuous sheet through said housing, said first conveying means including a first roller about which said continuous sheet is rolled and a second roller adapted to wind up said continuous sheet supplied from said first roller; a light source for emitting light sensible by said photosensitive microcapsules toward a manuscript placed on said manuscript table; light exposure means provided in said housing between said first and second rollers for exposing said light to said continuous sheet to duplicate a photoimage of said manuscript on said continuous sheet; contact means for bringing said recording medium into contact under pressure with said continuous sheet having been subjected to the light exposure, to thereby destroy said microcapsules of a portion not exposed to said light, whereby said dye precursor flowing out of said destroyed microcapsules reacts to said color developing agent on said recording medium to transfer said duplicated photo-image on said continuous sheet to said recording medium; and second conveying means for conveying said recording medium on which said duplicated photo-image has been developed, away from said continuous sheet, to the outside of said housing.

Claim 12

An imaging device wherein a continuous sheet carrying thereon photosensitive microcapsules each enveloping a dye precursor therein is utilized to form a latent image thereon, and a recording medium carrying thereon a color developing agent which reacts to said dye precursor to develop color is utilized to develop a visible image thereon, which comprises; a housing having a manuscript table; first conveying means for conveying said continuous sheet through said housing, said first conveying means including a first roller about which said continuous sheet is rolled and a second roller adapted to wind up said continuous sheet supplied from said first roller; a light source for emitting light sensible by said photosensitive microcapsules toward a manuscript placed on said manuscript table; light exposure means provided in said housing between said first and second rollers for exposing said light to said continuous sheet to duplicate a photoimage of said manuscript on said continuous sheet; contact means for bringing said recording medium into contact under pressure with said continuous sheet having been subjected to the light exposure, to thereby destroy said microcapsules of a portion not exposed to said light, whereby said dye precursor flowing out of said destroyed microcapsules reacts to said color developing agent on said recording medium to transfer said duplicated photo-image on said continuous sheet to said recording medium; and second conveying means for conveying said recording medium on which said duplicated photo-image has been developed, away from said continuous sheet, to the outside of said housing.
