PURPOSE: A portable terminal having an optical structure of combining an iris photographing function with a general photographing function is provided to add a camera lens which can obtain an iris image to confirm a personal identity, in order to enable iris and general photographing functions as a combination by using one CCD element, thereby realizing personal information security effects. CONSTITUTION: A T-shaped lens barrel(10) is formed, while a general photographing lens(20) is disposed on one side of the lens barrel(10). An iris photographing lens(30) is arranged on other side of the lens barrel(10), and a CCD element(40) is configured in an optical focal point. A beam splitter(50) is formed in a position where optical central points of the general photographing lens(20) and the iris photographing lens(30) are crossed together, so that each incident beam can be photographed in the CCD element(40). A lens barrel assembly is configured by forming a visible ray cut-off filter on an optical incident path of the iris photographing lens(30). A housing is embedded in the lens barrel assembly, while an optical opening/shutting apparatus for opening/shutting the incident beams is formed in front of each lens(20,30).
