Claim:
1. A mobile terminal comprising: a terminal body including a front case and a rear case; and a camera module disposed in the terminal body, the camera module having a housing, a first lens unit, a second lens unit and a moving unit connected to the first lens unit and the second lens unit, wherein at least a portion of the housing is exposed through an opening in the terminal body, wherein the first lens unit is disposed in the housing and has a plurality of lenses that focus light received through the exposed portion of the housing; wherein the second lens unit is disposed in the housing and magnifies an image formed by light passing through the first lens unit as a function of a distance between the first lens unit and the second lens unit; and wherein the moving unit comprises: a first shaft; a moving element in communication with the first shaft, the moving element extends and retracts the first shaft within the housing as a function of an amount of voltage applied to the moving element; a connection member connecting the first shaft to one of the first lens unit and the second lens unit in order to adjust the distance between the first lens unit and the second lens unit when the first shaft extends or retracts; a second shaft; a second moving element in communication with the second shaft, the second moving element that extends and retracts the second shaft within the housing as a function of an amount of voltage applied to the second moving element; and a second connection member connecting the second shaft to the other one of the first lens unit and the second lens unit in order to adjust the distance between the first lens unit and the second lens unit when the second shaft extends or retracts, wherein the first and second shafts are dual shafts, and wherein each dual shaft comprises: an outer shaft portion; and an inner shaft portion disposed within the outer shaft portion and in communication with the corresponding moving element, wherein at least a portion of the inner shaft extends or retracts within the outer shaft portion as a function of the voltage applied to the corresponding moving element.
