Abstract
In a microfilm reader-printer working according to the rotational principle one of the fixed deflecting mirrors (11, 12) by which the image is to be projected on an exposure area (13) is made and arranged in a flexible manner. A deflecting device (14) formed by a magnet coil (15) and a pusher rod (16) is continually bending one of the deflecting mirrors (11, 12) during the exposure of the base material in such a way that an image is produced that is free from distortions.
