Exposure device for homogeneously exposing to light of zones situated outside an image section on a photoconductive element. The exposure device comprises a light source (2), a housing (1) with a light-transmitting plane (12) and adjustable means for covering the light-transmitting plane (12). These adjustable means comprise a tube (16) rotatable about the housing (1) and provided with a helical edge (17) at the end that can extend over the light-transmitting plane (12) of the housing (1). A continuously adjustable part of the light-transmitting plane (12) can be covered by rotating the tube (16) about its axis. |
