A simple high-speed photocomposing machine is disclosed. Character images are projected from a stationary glass matrix plate through a fixed lens to a continuously moving film. Every matrix character may at all times be projected to any position on the film (see FIG. 1). The film is driven by a drive band. A timing control synchronized with the motion of the film ensures that proper character information is withdrawn from storage at the precise moment to trigger the projection of a character image to the correct location on the continuously moving film. In this manner a complete page of characters is composed virtually simultaneously.
