Abstract
An exposure station for a photocopier includes an illumination device positioned above a transport plane for a copy original, with a lamp as the source of the copy light, and a focusing hood positioned in the light path of the lamp between the lamp and the copy original. A projection lens system is positioned between the transport plane of the copy original and a transport plane for the copy material for reproducing the copy original on the copy material. By adjusting the projection lens system, for example, by selecting different lenses, it is possible to set different enlargement sizes. The luminance conditions of the copy light falling on the copy original can be adjusted to the enlargement size that has been set.
