ABSTRACT:
A high speed phototypesetter in which a font is selectively illuminated by motor-driven scanning mirrors and scanning motion is cancelled in the reflected image light by mirrors on the same driven shaft or shafts. The image beam from the font is then separated from the illuminating beam and focused at a selected location on a photocomposing surface to provide a focused image of a font character.
