徴とする複写機の変倍機構。 In a variable magnification copying machine that uses a fixed focus lens and can change the copying magnification by changing the position of the lens and mirror, lens position adjustment allows the position of the lens in the optical axis direction to be changed in accordance with the copying magnification. a mirror moving means capable of changing the optical path length by moving a mirror interposed between a lens and a drum-shaped photoreceptor in the optical axis direction; a mirror angle adjustment means for adjusting the angle of the mirror;
The lens position adjusting means and the mirror moving means are connected to each other, and a cable is provided to transmit a motion so that the movement of the lens is used to move the mirror, and the cable is fixed at a predetermined position and is made to follow the curved surface of the cable. A variable magnification mechanism for a copying machine, comprising: a cam, the cam having a shape so as to convert an amount of movement of a lens according to a copying magnification into an amount of movement of a mirror according to the copying magnification.
