続変倍機構。 In a variable copying magnification type copying machine using a zoom lens consisting of a distance adjusting lens barrel and a zoom adjusting lens barrel, the position of the distance adjusting lens barrel is adjusted by moving the zoom lens in the optical axis direction in accordance with the copying magnification. A zoom lens movement adjustment means, a cam follower that moves together with the zoom lens, a fixed cam that follows the cam follower, and a cable that transmits movement so that the movement of the cam follower is used to move the zoom adjustment lens barrel. The cam is divided into a plurality of parts in the optical axis direction, and the relative position between adjacent parts can be changed, and the focal length corresponding to the copying magnification is obtained from the amount of movement of the zoom lens corresponding to the copying magnification. The lens is shaped so that the zoom adjustment lens barrel can be rotated by a predetermined amount, and by changing the position of the divided portions, the shape can be slightly changed to absorb variations in the focal length of the zoom lens. A continuous variable magnification mechanism for copying machines.
