Abstract
A photocopying apparatus is provided in which a moving area of a lens at the time of a magnification changing and that of an optical device such as a mirror unit overlap partly. At the time of the magnification changing, it is determined whether the optical device is positioned at a home position. When the optical device is not located at the home position, the lens is caused to move for the purpose of the magnification changing after the optical device is returned to the home position.
