する複写機の連続変倍機構。 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 forming a threaded pair with the same distance adjusting lens barrel, the zoom lens is moved in the optical axis direction in accordance with the copying magnification. a zoom lens movement adjusting means for adjusting the position of the distance adjusting lens barrel; a cam follower provided protruding from the zoom adjusting lens barrel; and controlling the amount of rotation of the zoom adjusting lens barrel by regulating the movement of the cam follower. The curved cam has a shape that allows the zoom adjustment lens barrel to be rotated by a predetermined amount in order to obtain a focal length corresponding to the copying magnification based on the amount of movement of the zoom lens corresponding to the copying magnification. Continuous variable magnification mechanism of a copying machine.
