ことを特徴とする、変倍光学系。[Scope of Claim for Utility Model Registration] In an analog copying machine capable of variable magnification, in order to change the copying magnification, a variable mirror that can be displaced is disposed on the object side and the image side of the imaging lens to realize a reduction magnification. To achieve magnification, the imaging lens and variable mirror on the object side are displaced, and to achieve magnification, the imaging lens and variable mirror on the image side are displaced to realize an optical arrangement according to the magnification. A variable magnification optical system characterized by:
