のレンズと前記感光体との間に少くとも２枚のミラーを
介在させ、これら２枚のミラーを共通のミラー保持部材
に固定し、該ミラー保持部材を前記レンズの光軸に平行
に移動させることにより変倍時の共役長変更を行うよう
にした複写機において、前記ミラー保持部材を前記レン
ズに大きな遊びをもって従動させることにより、変倍に
際しレンズを移動させて先ず前記ミラー保持部材の位置

特徴とする複写機の変倍機構。an optical system for projecting an image of an original onto a photoconductor, at least two mirrors are interposed between a lens in the optical system and the photoconductor, and these two mirrors are mounted on a common mirror holding member; In a copying machine in which the mirror holding member is fixed and the conjugate length is changed during zooming by moving the mirror holding member parallel to the optical axis of the lens, the mirror holding member is caused to follow the lens with a large play. A magnification changing mechanism for a copying machine, characterized in that when changing magnification, the lens is moved to first determine the position of the mirror holding member, and then the lens position is adjusted.
