Abstract
Det er tilveiebrakt en lampe-enhet til bruk i en elektrofotografisk kopieringsmaskin. Lampe-enheten. son inneholder en lampe, beveger seg under en original som ligger på en original-støtteplate. Lampe-enheten er tildannet med en spalte, gjennom hvilken lyset fra lampen avgis mot originalen og reflekteres av den mot et lysfølsomt objekt i den hensikt å danne et bilde på dette. Spalten er på sitt smaleste ved sitt sentrale område, og utvider seg gradvis mot begge sine ender. Dessuten akselereres lampe-enheten inntil den når sentrum av original-støtteplaten, og nedbremses deretter. Dette sikrer en ensartet fordeling av lys over det lysfalsomme objektets overflate.
