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, and an image receiving material. The photosensitive material and the image receiving material being adapted to be superposed one on the other and pressed to each other so as to transfer the image from the photosensitive material to the image receiving material. The pressing of these two materials is conducted by a means which includes a pair of pressing rolls for nipping the photosensitive material and the image receiving material therebetween; back-up rolls means having an axial length smaller than that of the pressing rolls and adapted for acting on at least one of the pressing rolls; and back-up roll pressing means capable of independently adjusting the pressure exerted by the back-up roll means on the pressing rolls.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 180 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 photosensitive and heat-developable and which enables the developed image to be fixed by a pressure, at least part of said photosensitive and heat-developable material being contained in common microcapsules, and an image receiving material, said photosensitive material and said image receiving material being adapted to be superposed one on the other and pressed to each other so as to transfer the image from said photosensitive material to said image receiving material, said apparatus comprising: a pair of pressing rolls for nipping said photosensitive material and said image receiving material therebetween; and means for applying a uniform contact pressure between said pair of pressing rolls; said means comprising, back-up roll means having an axial length smaller than that of said pressing rolls and adapted for acting on at least one of said pressing rolls; and back-up roll pressing means capable of independently adjusting the pressure exerted by said back-up roll means on said pressing rolls.
Claim 2
Dependent Claim 180 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 photosensitive and heat-developable and which enables the developed image to be fixed by a pressure, at least part of said photosensitive and heat-developable material being contained in common microcapsules, and an image receiving material, said photosensitive material and said image receiving material being adapted to be superposed one on the other and pressed to each other so as to transfer the image from said photosensitive material to said image receiving material, said apparatus comprising: a pair of pressing rolls for nipping said photosensitive material and said image receiving material therebetween; and means for applying a uniform contact pressure between said pair of pressing rolls; said means comprising, back-up roll means having an axial length smaller than that of said pressing rolls and adapted for acting on at least one of said pressing rolls; and back-up roll pressing means capable of independently adjusting the pressure exerted by said back-up roll means on said pressing rolls.
Claim 3
Dependent Claim 20 words
An image recording apparatus according to claim 1, wherein said pair of pressing rolls have axes parallel to each other.
Claim 4
Dependent Claim 19 words
An image recording apparatus according to claim 1, wherein said back-up roll means includes a plurality of back-up rolls.
Claim 5
Dependent Claim 34 words

Claim 6
Dependent Claim 25 words
An image recording apparatus according to claim 1, wherein said photosensitive material and said image receiving material are supplied from respective rolls of these materials.
Claim 7
Dependent Claim 26 words
An image recording apparatus according to claim 1, wherein said photosensitive material and said image receiving material are supplied in the form of separate sheets, respectively.
Claim 8
Dependent Claim 35 words
An image recording apparatus according to claim 1, wherein said photosensitive material is supplied in the form of separate sheets, while said image receiving material is supplied from a roll of such image receiving material.
Claim 9
Dependent Claim 25 words
An image recording apparatus according to claim 1, wherein said photosensitive material and said image receiving materials are supplied from rolls of the respective material.
Claim 10
Dependent Claim 23 words
An image recording apparatus according to claim 8, wherein said photosensitive material after the transfer is taken-up into the form of a roll.
Claim 11
Dependent Claim 24 words
An image recording apparatus according to claim 8, wherein said photosensitive material after the transfer is taken-up in the form of a separate sheet.
Claim 12
Dependent Claim 24 words
An image recording apparatus according to claim 8, wherein said image receiving material after the transfer is taken-up into the form of a roll.
Claim 13
Dependent Claim 25 words
An image recording apparatus according to claim 8, wherein said image receiving material after the transfer is taken-up in the form of a separate sheet.
Claim 14
Dependent Claim 35 words
An image recording apparatus according to claim 1, wherein said photosensitive material is supplied in the for of separate sheets while said image receiving materials is supplied from a roll of said image receiving material.
Claim 15
Dependent Claim 18 words
