Abstract
A novel original illuminator of electrophotographic copying machine capable of leading the majority of light from the illuminant onto the original surface placed on the contact glass by applying the condenser mirror to allow the light not oriented to the original to reflect itself by a mirror opposite from the condenser mirror before eventually leading light to the illuminant over again.
