ABSTRACT:
A zoom lens driving apparatus achieves the object of driving multiple lens groups by a single motor and low production cost. When a first lens group, which includes a first lens, moves along guide rods, a leading cam of a leading member drives a leading pin of a follower, so that the follower moves a guide pin, and moves a second lens group, which includes a second lens, along the guide rods. The relative distance between the first lens group and the second lens group is controlled by the leading cam.
