ABSTRACT:
The slit exposure optical system for a copying machine generally includes two mirror-carrying movable tables of which one is driven at half the speed of the other. Normally each table is driven from one and the same end which means that the other end of each table must follow. If such following is not precise, aberrations in the optical system result. The present invention provides means for interconnecting the nondriver ends of the tables in such a manner that the movement of the nondriver ends will precisely follow the movement of the driver ends and aberrations are thereby avoided.
