Abstract
An optical apparatus and reproducing machine includes an optical system for viewing a document and for projecting an image thereof onto a moving imaging surface. A plurality of optical elements are arranged along an optical path. The projected image magnification is changed by changing the position of at least two optical elements. An interlock apparatus associated with the magnification changing system is provided for inhibiting the change in position of one of the two optical elements until the other of the two optical elements has completed its change in position, upon the changing of the magnification of the optical system.
