ABSTRACT:
A moving mechanism for a camera lens assembly includes a smooth concave face formed in a surface of the camera main body, a slot formed in the concave face, a first cable extending from the shutter assembly and having at least two wires, a rotatable tube surrounding the cable and having an axial groove, a first plate rotatable with the tube and having at least two electrically conductive rings which are respectively connected to the at least two wires of the first cable, and a second plate fixed against rotation relative to the camera main body and having at least two conductive rings connected to two wires of a second cable extending from the camera main body. The slot in the camera main body is in the shape of a cross and the first plate includes a projection that enables the first plate to move in the two directions permitted by the slot while preventing rotation of the first plate relative to the main body so that, in the case of movement in the left-right or forward-backward directions, the projection does not impede movement of the first plate and the tube, first plate, and second plate all move together in the selected direction, while in the case of rotation about the vertical axis, the first plate is prevented from rotation and only the tube and second plate are rotated together, with the shutter assembly and the first plate rotating relative to the second plate.
