されたことを特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. means, a mirror moving means capable of changing the optical path length by moving the mirror in the optical axis direction, and the lens position adjusting means and the mirror moving means are connected, and the movement of the lens is caused by the movement of the mirror. The cam includes a cable that transmits motion to be used, and a cam that is fixed at a predetermined position and causes the cable to follow the curved surface of the cable. A variable magnification mechanism for a copying machine, characterized in that a shape is formed to convert the amount of movement into the amount of movement.
