    摘要: A border discharge device for an electrophotographic copier comprises a row of light emitting diodes (42 to 74) positioned adjacent light channel sections (90 to 93). The channels (90, 91 and 93) provide edge erase and channel (92), together with the others, provide inter-image erase, the diodes being selectively energised to effect these functions. The channels comprise blocks of transparent material having reflective upper and lower surfaces to allow propogation of light rays from each diode to the photoconductive imaging element at a plurality of angles of incidence. Thus each channel provides a substantially uniformly illuminated strip area.
