摘要:
A photocopying system without using an intermediate film is disclosed. In this system, the photo-pressure sensitive sheet and an original are tightly overlapped on a photocopying stage. Scratching scars generated by friction therebetween can be avoided by drive means for changing a distance therebetween. Images on the reverse side of the original can be protected from being duplicated by changing a direction of a light beam. Figure/character images, as well as image trimming, can be arbitrarily photocopied by exposing to a light through display on liquid crystal panel.
