Abstract
Abstract Disclosed is a method of recording a picture onto a photosensitive and pressure-sensitive paper, which comprises the steps of: forming in advance a mask original form of a film having a light-transmitting portion and a non-light-transmitting portion corresponding to information of the picture; exposing the photosensitive and pressure-sensitive paper through the mask original form to thereby form a latent image on the photosensitive and pressure-sensitive paper; and pressure-fixing the photosensitive and pressure-sensitive paper carrying the latent image formed thereon. Further disclosed is an apparatus for carrying out the above method, which comprises: a mask forming means for forming a mask original form of a film having a light-transmitting portion and a non-light-transmitting portion corresponding to picture information of an original picture; an exposure means for exposing the photosensitive and pressure-sensitive paper through the mask original form formed by the mask forming means; and a pressure-fixing means for pressing the photosensitive and pressure-sensitive paper having a latent image formed by the exposure means to thereby perform pressure-development.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
131 words
An apparatus for recording a picture onto a photosensitive and pressure-sensitive sheet, comprising: forming means for forming plural mask original forms based on picture information entered through an input means which electronically emulates said picture so that said mask original forms have light-transmitting portions and non-light-transmitting portions corresponding to picture information of said original picture; positioning means for accurately adjusting each of said plural mask original forms with respect to the photosensitive and pressure-sensitive sheet; exposure means for exposing said photosensitive and pressure-sensitive sheet through said mask original forms to light of plural different wavelengths whereby to produce a latent image of said picture on said photosensitive and pressure-sensitive sheet; and pressure-fixing means for pressing said photosensitive and pressure-sensitive sheet having said latent image thereon to thereby develop said latent image.
Claim 2
Independent Claim
131 words
An apparatus for recording a picture onto a photosensitive and pressure-sensitive sheet, comprising: forming means for forming plural mask original forms based on picture information entered through an input means which electronically emulates said picture so that said mask original forms have light-transmitting portions and non-light-transmitting portions corresponding to picture information of said original picture; positioning means for accurately adjusting each of said plural mask original forms with respect to the photosensitive and pressure-sensitive sheet; exposure means for exposing said photosensitive and pressure-sensitive sheet through said mask original forms to light of plural different wavelengths whereby to produce a latent image of said picture on said photosensitive and pressure-sensitive sheet; and pressure-fixing means for pressing said photosensitive and pressure-sensitive sheet having said latent image thereon to thereby develop said latent image.
Claim 3
Dependent Claim
60 words
A picture recording apparatus according to claim 1, in which said mask forming means includes an input device for inputting image data respectively for colors on the basis of said picture information, and thermal transfer device for thermally successively transferring said inputted image data respectively for said colors onto a film for forming a mask original form for every color.
Claim 4
Dependent Claim
86 words
A picture recording apparatus according to claim 1, in which said mask forming means includes a visible radiation spectro-filter for transmitting specific color light part of reflection light from said original picture irradiated with light, a photosensitive means for forming a latent image on a mask original form forming film by the light transmitted through said visible radiation spectrofilter, and a developing and fixing means for developing and fixing said mask original form forming film to make said film to selectively partly have light transmission property.
Claim 5
Dependent Claim
41 words
A picture recording apparatus according to claim 1, in which said mask forming means includes means for reading said picture information of said original picture, and means for impact-printing the read picture information onto a light transmitting film with non-transmitting ink.
Claim 6
Dependent Claim
73 words
A picture recording apparatus according to claim 1, in which said mask forming means includes a visible light source for scanning an original picture, a photosensitive body for forming an electrostatic latent image thereon corresponding to the picture information of said scanned original picture, a toner-developing means for applying toners onto said photosensitive body, and a transfer means for transferring the toners from said photosensitive body onto a surface of a light-transmitting film.
Claim 7
Dependent Claim
49 words
A picture recording apparatus according to claim 5, in which said mask forming means further includes a fixing means for fixing the toners on said light-transmitting film, and a change-over means for selectively switching an operation mode of said fixing means between an operable mode and an inoperable mode.
Claim 8
Dependent Claim
33 words
The apparatus in accordance with claim 1 wherein said positioning means includes means for applying a plurality index marks to each of said mask original forms and means for detecting said index marks.
Claim 9
Dependent Claim
47 words
The apparatus in accordance with claim 7 wherein said photosensitive and pressure sensitive sheet is fed in a longitudinal direction and said applying means applies said index marks in said longitudinal direction and in a direction orthogonal thereto for adjusting the position of said mask original forms.
Claim 10
Dependent Claim
50 words
The apparatus in accordance with claim 7 wherein said index mark applying means comprises means for perforating holes into said mask original forms and said detecting means includes a light source for directing a light through said holes and a light sensing element for receiving light passing through said holes.
