Abstract
An enlargement lens is moved to a retracted position by driving a lens moving deck, and temporarily transferred onto a lens storing deck. After the lens moving deck is returned to its initial position, the enlargement lens is rotatably supported on support rails and rotated about its rotatable shaft to expose a lens surface to the outside for the cleaning. Accordingly, the enlargement lens can easily be cleaned.
