Abstract
In an electrophotographic copying apparatus of the type using a slit exposure optical system, two carriages carrying a light source and the means for directing an image toward a projection lens are driven relatively to one another through a wire sheave device. The impact energy of said carriages at travel end is absorbed not only by a compressible spring positioned between them, but also by the stretching of the wire which moves them relatively to one another.
