Abstract
A condenser device for lighting an original as used in a facsimile or copying machine incorporates an elliptical or similar reflecting mirror. A light shield associated with a light source is provided with a pair of reflecting surfaces, one of which directs light incident thereon from the light source onto the elliptical reflecting mirror and thence to the other surface for reflection to a slitwise area to be scanned where it is combined with light following a direct path including the light source and the mirror.
