Abstract: An optical imaging lens includes a lens barrel, a front lens element, plural intermediate lens elements, and a rear lens element. The front lens element has a first central lens portion and a first assembly portion. The first assembly portion has a first front abutting section, a first front slanting surface section, and a first rear slanting surface section. Each of the intermediate lens elements has a second central lens portion and a second assembly portion. The second assembly portion has a second front slanting surface section and a second rear slanting surface section. The rear lens element has a third central lens portion and a third assembly portion. The third assembly portion has a third front slanting surface section.

Abstract: An auto-focusing zoom lens mechanism includes a base unit forming a space; an auto-focusing (AF) lens unit located in the base unit and having a trajectory bar engaged therewith; a zoom lens unit located in the base unit and mounted on the AF lens unit and having a trajectory bar engaged therewith; a cam plate unit engaged with the AF lens unit and the zoom lens unit and provided with an AF trajectory groove and a zoom trajectory groove to receive the trajectory bars of the AF lens unit and the zoom lens unit; and a step motor unit engaged with the cam plate unit to drive the cam plate unit, the AF lens unit and the zoom lens unit moving.

Abstract: A zoom lens barrel includes a first stationary cylinder defining an optical axis. The first stationary cylinder has a tubular wall surrounding a passage. A guiding and positioning slot is defined in the tubular wall along the optical axis with a plurality of anchor points and block points alternately arranged on edges thereof. A first lens carrier is held in the passage and has a driving pole. A second lens carrier surrounds the tubular wall and has a retainer and a first guiding slot. A second stationary cylinder surrounds the second lens carrier and has a stopper and a second guiding slot. The driving pole passes through the guiding and positioning slot, the first and the second guiding slot and is positioned in one of the anchor points. The spring is retained between the first stationary cylinder and the second lens carrier to push the second lens carrier moving with the first lens carrier till the retainer is blocked by the stopper.
