Abstract

The invention relates to an optical printer in which light signals emitted by an information-controlled light source are applied to a photosensitive record carrier via a mirror system and a circular-to-linear converter which consists of optical fibers. In order to improve the optical coupling between the light source and the record carrier and hence the printing quality, the mirror system comprises a conical mirror which opens in the direction of the circular-to-linear converter and which enables the light beam to be axially coupled into the circularly arranged ends of the optical fibers at the entrance of the circular-to-linear converter.
