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.
