Abstract

An arrangement for optoelectrically scanning a master employs a scanning device having a plurality of scanning elements which simultaneously scan a plurality of parallel lines of a row, the master being displaced at right angles to the scanning direction. The scanning device, like a mosaic printing head, is disposed on a printing carriage of a printing station which moves along a platen and the master to be scanned can be placed around the platen which displaces the master as scanning takes place. In one embodiment the scanning device includes scanning elements which are disposed like the printing elements of a mosaic printing head and the scanned points communicate with the scanning elements through light tunnels, which tunnels may include light guides. In another embodiment, the scanning device includes a lens which focuses the scan points on the scanning elements.
