发明名称 Contact duplicator for reproducing developed images
摘要 The images are applied from a film (10) coming from a roll (14) on an electrophotographic film (12) coming from a roll (18). A thin layer of insulating hydrocarbon (41) is applied onto the electrophotographic film (12) before it enters into contact with the film (10) in order to prevent static discharge when the two films are separated. The films (10 and 12) of the two rolls (14 and 18) are placed in contact and conveyed to a projection station (22) where a light beam is projected onto and through them. The electrophotographic film (12) is charged just before it is placed in contact with the photographic film. A station for applying toner (26) and a fixing station (54) are arranged in order to act on the electrophotographic film after its exposure. The subsequent transfer of the image provided with toner onto a strip of base film is provided in order to allow subsequent reuse of the electrophotographic film (12). <IMAGE>
