Abstract
Abstract An image recording apparatus employs a photo- and pressure-sensitive heat-developable material having a substrate and a layer formed on the substrate from a material which is photo-sensitive and heat-developable and which enables the developed image to be fixed by a pressure. The apparatus has the following major parts: an exposure device for exposing the material to an original image so as to form a latent image corresponding to the original image on the photo-sensitive material; a heat-developing device for thermally setting the portion of the material corresponding to the latent image thereby immobilizing the image; a pressing transfer device for superposing the material and an image-receiving material in contact with each other and pressing them together; and a conveyor drum defining a path of convey therearound. At least two of the exposure device, the heat-developing device and the pressing transfer device being arranged along the path.

Total Claims: 8
Claim 1
Independent Claim
143 words
An image recording apparatus which employs a photo- and pressure-sensitive heat-developable material having a substrate and a layer formed on said substrate from a material which is photo-sensitive and heat-developable and which enables the developed image to be fixed by a pressure, said apparatus comprising: an exposure device for exposing said material to an original image so as to form a latent image corresponding to said original image on said material; a heat-developing device for thermally setting the portion of said material corresponding to said latent image thereby immobilizing said image; a pressing transfer device for superposing said photo-sensitive material and an image-receiving material in contact with each other and pressing them together; and a conveyor drum defining a path of conveyance therearound, at least two of said exposure device, said heat-developing device and said pressing transfer device being arranged along said path.
Claim 2
Dependent Claim
143 words
An image recording apparatus which employs a photo- and pressure-sensitive heat-developable material having a substrate and a layer formed on said substrate from a material which is photo-sensitive and heat-developable and which enables the developed image to be fixed by a pressure, said apparatus comprising: an exposure device for exposing said material to an original image so as to form a latent image corresponding to said original image on said material; a heat-developing device for thermally setting the portion of said material corresponding to said latent image thereby immobilizing said image; a pressing transfer device for superposing said photo-sensitive material and an image-receiving material in contact with each other and pressing them together; and a conveyor drum defining a path of conveyance therearound, at least two of said exposure device, said heat-developing device and said pressing transfer device being arranged along said path.
Claim 3
Dependent Claim
60 words
An image recording apparatus according to claim 1, wherein said material is composed of a substrate and a layer formed on said substrate from a composition which contains a photo-sensitive silver halide, a reducing agent, a polymerizable compound and a color-image forming material, and wherein at least said polymerizable compound and said color-image forming material are charged in common capsules.
Claim 4
Dependent Claim
39 words
An image recording apparatus according to claim 1, wherein said heat-developing device is adapted to cause said polymerizable compound in said capsules located in the area corresponding to said latent image, thus thermally setting said microcapsules in said area.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
27 words
An image recording apparatus according to claim 1, wherein said exposure device and said pressing transfer device are disposed along said path defined by said conveyor drum.
Claim 7
Dependent Claim
26 words
An image recording apparatus according to claim 1, wherein said exposure device and said heat-developing device are disposed along said path defined by said conveyor drum.
Claim 8
Dependent Claim
27 words
An image recording apparatus according to claim 1, wherein said heat-developing device and said pressing transfer device are disposed along said path defined by said conveyor drum.
