Abstract
Abstract An image recording apparatus for providing an image on a photosensitive recording medium comprising: a light-transmissive image carrier for carrying a light shielding image thereon; image forming means for forming the light-shielding image on the image carrier based on given image information; exposure means which applies light to the photosensitive recording medium through the image carrier for forming a latent image on the photosensitive recording medium, the photosensitive recording medium being disposed in confronting relation with the image carrier at least at the exposure means; image developing means disposed at downstream side of the exposure means for visualizing the latent image on the photosensitive recording medium; enlarging means connected to the image forming means for providing an enlarged image information to form the light-shielding image having enlarged size on the image carrier with respect to the image information; and reducing means disposed at the exposure means for reducing the latent image to be formed on the photosensitive recording medium with respect to the light-shielding image on the image carrier.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
169 words
An image recording apparatus for providing an image on a photosensitive recording medium comprising: a light-transmissive image carrier for carrying a light shielding image thereon; image forming means for forming said light-shielding image on said image carrier based on given image information; exposure means which applies light to said photosensitive recording medium through said image carrier for forming a latent image on said photosensitive recording medium, said photosensitive recording medium being disposed in confronting relation with said image carrier at least at said exposure means; image developing means disposed at downstream side of said exposure means for visualizing said latent image on said photosensitive recording medium; enlarging means connected to said image forming means for providing an enlarged image information to form said light-shielding image having enlarged size on said image carrier with respect to said image information; and reducing means disposed at said exposure means for reducing said latent image to be formed on said photosensitive recording medium with respective to the light-shielding image on said image carrier.
Claim 2
Dependent Claim
169 words
An image recording apparatus for providing an image on a photosensitive recording medium comprising: a light-transmissive image carrier for carrying a light shielding image thereon; image forming means for forming said light-shielding image on said image carrier based on given image information; exposure means which applies light to said photosensitive recording medium through said image carrier for forming a latent image on said photosensitive recording medium, said photosensitive recording medium being disposed in confronting relation with said image carrier at least at said exposure means; image developing means disposed at downstream side of said exposure means for visualizing said latent image on said photosensitive recording medium; enlarging means connected to said image forming means for providing an enlarged image information to form said light-shielding image having enlarged size on said image carrier with respect to said image information; and reducing means disposed at said exposure means for reducing said latent image to be formed on said photosensitive recording medium with respective to the light-shielding image on said image carrier.
Claim 3
Dependent Claim
56 words
The image recording apparatus as defined in claim 1, wherein said enlarging means provides magnification ratio of M between said given image information and said light shielding image on said image carrier, and said reducing means provides a reduction ratio of 1/M between said light shielding image and said latent image on said photosensitive recording medium.
Claim 4
Dependent Claim
37 words
An image recording apparatus as defined in claim 1, further comprising a pair of rollers on which said image carrier is wound at respective opposite ends thereof, said rollers being rotatable to move said image carrier therebetween.
Claim 5
Dependent Claim
39 words
The image recording apparatus as defined in claim 1, wherein said photosensitive recording medium comprises a self-contained type recording medium in which an encapsulated chromogenic material and a developer material are co-deposited on one surface of a single substrate.
Claim 6
Dependent Claim
85 words
The image recording apparatus as defined in claim 1, wherein said photosensitive recording medium comprises a separate type recording medium in which an encapsulated chromogenic material is deposited on a first substrate and a developer material is coated on a second substrate as a separate developer sheet, and further comprising a means for feeding said separate developer sheet to said image developing means for superposing with said first substrate which carries said latent image, whereby said visualized image is formed on said separate developer sheet.
Claim 7
Dependent Claim
99 words
The image recording apparatus as defined in claim 1, wherein said image forming means comprises: a laser scanner unit for applying a laser beam; a xerographic unit disposed at a position adjacent to said laser scanner unit for forming an electrostatic latent image responsive to said laser beam and for providing a toner image corresponding to said electrostatic latent image; and, an image transfer roller disposed in confrontation with said xerographical unit for transferring said toner image onto said light-transmissive image carrier to thereby provide said light-shielding image thereon, said enlarging means being connected to said laser scanner unit.
Claim 8
Dependent Claim
72 words
The image recording apparatus as defined in claim 1, wherein said image forming means comprises; a magnetographic unit for providing a magnetic latent image based on said given image information so as to provide said light-shielding image at said magnetic latent image; and, a transfer roller for transferring said light-shielding image onto said image carrier, said transfer roller being applied with electrical charges, said enlarging means being connected to said magnetographic unit.
