Beschreibung
Zusammenfassung:	A reproduction camera comprising a picture plane, an original plane and an objective plane, whereby the original plane is exposed by means of at least one elongated light source preferably situated below said original plane and optionally scanning at a varying velocity. The light source is turned during the scanning procedure in such a manner that it is directed towards the objective. Preferably, the elongated light source situated below the original plane comprises at least one reflector, at least a portion of said reflector being turnable during the scanning procedure in such a manner that the light reflected is always directed towards the objective. As a result a better utilization of the light is obtained. Preferably, the reflector is shaped in such a manner that a uniform beam is obtained within a predetermined angle, whereby the light source need not be turned during the scanning procedure.
