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.

Abstract: A Venetian blind lifting mechanism is composed of a slat set, a winding member, a slat winding cord, and a locating member. The slat set has a plurality of slats. The winding member has at least one cord pulling member and at least one spring releasing unit which is linked with the cord pulling member. The cord pulling member has one end which is extended through the slat set, and other end which is fastened with the cord pulling member. The locating member has a retaining member capable of bringing about a retaining force to overcome the rewinding force of the winding member so as to stabilize the cord pulling member.

Abstract: A Venetian blind is provided with a slat-lifting mechanism consisting of a slat set, a slat pull cord, and a constant torque pull set. The slat set has a plurality of slats. The slat pull cord is connected with each of the slats of the slat set and is put through the bottommost end of the slat set. The constant torque pull set is disposed at the top end of the slat set and composed of a pull cord member and a constant torque spring unit which is linked with the pull cord member and provided with a constant torque spring which has a constant retrieving force enabling the pull cord member to rewind. The constant retrieving force of the constant torque spring must meet the condition of W-Fs
