ABSTRACT:
Transverse areas lying between image areas of a moving photoconductive element can be discharged efficiently with sharp demarcations between the respective areas by an exposure device in which a flash lamp is disposed perpendicularly between two elongate side walls of a reflective housing having an open side and an elongate light-reflecting rear wall. A protective cover fixed near the lamp at the open side prevents direct radiation of the element from the lamp. Scatter of the reflected light is prevented by partitions fixed in parallel to the side walls in end regions of the housing space.
