Abstract
A microfilm reader with a lens holder moved independently of a lighting unit at right angles in relation to the beam path by means of a drive unit. This renders it possible to correctly position any of a plurality of lenses arranged side by side in the lens holder in relation to the frame to be projected. Given that the lighting unit and the lens holder are capable of moving independently of each other, it is furthermore possible to shift the lighting unit into a position above the respective frame to be projected to obtain an image that is optimally illuminated.
