Image exposure device for exposing photosensitive recording medium to color image lights

Claim 2

An exposure device used in an image forming apparatus for exposing a photosensitive recording medium carrying microcapsules on one surface thereof to color image lights produced in accordance with color image data representing an original image to form a latent image corresponding to the original image, comprising: exposing means having plural exposing surfaces for producing the color image lights in accordance with the color image data and selectively exposing the photosensitive recording medium to the color image lights to form the latent image on the photosensitive recording medium, said exposing surfaces being disposed in such a manner as to confront the other surface of the photosensitive recording medium; and control means for driving and controlling said exposing means to produce the color image lights in accordance with the image data inputted thereto and expose the color image lights to the photosensitive recording medium.

Claim 3

An image exposure device as claimed in claim 1, wherein said exposing means comprises a fiber optics tube having red, green and blue phosphor surfaces serving as the exposing surface for emitting the color image lights in accordance with the image data.

Claim 4

An image exposure device as claimed in claim 2, wherein said exposing means further comprises an optical fiber array provided on said exposing surface for guiding the color image lights produced on the exposing surface.

Claim 5

An image exposure device as claimed in claim 1, wherein the photosensitive recording medium comprises a transparent support member and microcapsules coated on said support member.

Claim 6

An image exposure device as claimed in claim 1, wherein said control means comprises a fiber optics tube driving circuit for driving said fiber optics tube, a random access memory for storing the color image data therein and a processor for controlling said fiber optics tube driving circuit in accordance with the color image data stored in said random access memory.

Claim 7

An image forming apparatus for exposing a photosensitive recording medium carrying microcapsules on one surface thereof to color image lights produced in accordance with color image data representing an original image to form a latent image corresponding to the original image and developing the latent image on the photosensitive recording medium into a visible image on a developer sheet, comprising: a fiber optics tube having plural color phosphor surfaces serving as an exposing surface for producing the color image lights in accordance with the color image data and selectively exposing the photosensitive recording medium to the color image lights in accordance with the color image data, said color phosphor surfaces being disposed in such a manner as to confront the other surface of the photosensitive recording medium; a control unit for storing the color image data therein and controlling said fiber optics tube in accordance with the color image data so that the color image lights are selectively produced and irradiated to the photosensitive recording medium; a pressure-developing unit for applying a pressure to the photosensitive recording medium having the latent image thereon while the photosensitive recording medium is superposed on the developer sheet, thereby developing the latent image on the photosensitive recording medium into a visible image on the developer sheet; and a heat-fixing unit for thermally fixing the visible image on the developer sheet.

Claim 8

An image forming apparatus for exposing a photosensitive recording medium carrying microcapsules on one surface thereof to color image lights produced in accordance with color image data representing an original image to form a latent image corresponding to the original image and developing the latent image on the photosensitive recording medium into a visible image on a developer sheet, comprising: a fiber optics tube having plural color phosphor surfaces serving as an exposing surface for producing the color image lights in accordance with the color image data and selectively exposing the photosensitive recording medium to the color image lights in accordance with the color image data, said color phosphor surfaces being disposed in such a manner as to confront the other surface of the photosensitive recording medium; a control unit for storing the color image data therein and controlling said fiber optics tube in accordance with the color image data so that the color image lights are selectively produced and irradiated to the photosensitive recording medium; a pressure-developing unit for applying a pressure to the photosensitive recording medium having the latent image thereon while the photosensitive recording medium is superposed on the developer sheet, thereby developing the latent image on the photosensitive recording medium into a visible image on the developer sheet; and a heat-fixing unit for thermally fixing the visible image on the developer sheet.
