ABSTRACT:
In an optical scanning system for a copying apparatus, it is known to reciprocate the equipment so that an image to be scanned is applied, for example, to a photosensitive drum, developed, and eventually applied to a recording medium. It is essential for each scanning cycle that the scanning function restart at the proper starting position. This objective is attained by the present invention which first moves the scanning equipment back to a position spaced from the initial starting position and only then completes the movement to the initial starting position. Strains on the equipment involved in an immediate forcible return to the initial starting position are thereby avoided.
