Abstract

1306641 Photographic reader printers PENTACON DRESDEN KAMERA-UND KINOWERKE VEB 5 May 1971 13136/71 Heading G2A A photographic reader printer comprises an illumination system, formed by a lamp 3 and condenser 4, for a transparency 2; a projection lens 5; a mirror 6 rotatable about the optical axis I of the illumination system; fixed mirrors 7-9; an integral viewing screen 10 and an exposure station for printing an image on photosensitive material 11. The mirror 6 is rotatable by a motor driven shaft 13 obliquely connected to the mirror, between two positions obliquely inclined to the axis I. In its solid line position, light is reflected by the mirror 6 via the mirrors 7, 8 to the exposure station which is parallel to the transparency, and in its dotted line position light is reflected by the mirror 6 via the mirror 9 to the screen 10 which is approximately perpendicular to the exposure station. In another embodiment, Fig.6 (not shown), the drive shaft (35) is parallel to the mirror surface.
