Abstract
An optical illumination device for use in a copying apparatus of the type wherein an object is to be illuminated and an image thereof is to be projected through a particular image transmitter formed of a plurality of optical fibers of graded refractive index in bundled configuration to a light sensitive surface, comprises a source of illumination light and a light guide duct of substantially flattened cubic body. The light guide duct is designed such that rays of light from the light source accommodated within the light guide duct are directed towards a curved reflective surface and subsequently converge at one point on the transparent support structure for the support of the original to be copied thereon to form a strip or ribbon of light available for illumination of the original to be copied.
