Abstract
A photographic copier has a station which serves as a scanning station and a copying station. The station includes a support for an image to be scanned and copied, and a single light source for scanning and copying. A light-diffusing member is disposed between the light source and the support, and the light-diffusing member has a first condition for copying and a second condition for scanning. Light undergoes a high degree of diffusion in the first condition and a lower degree of, or substantially no, diffusion in the second condition.
