A device for picturing an iris pattern using a digital camera module and a single focal lens is provided to picture the iris pattern in a predetermined distance by using the lens of a simple single focal mode and picture a clear image while using a simple lighting structure of low illumination by making a user easily place an iris within a focal distance without a complex device. A single focal digital camera(110) is installed in a main body case(100), and pictures the iris pattern by including a lens module(111) and a CCD(Charge Coupled Device)(115). An LED(Light Emitting Diode) lamp(121) offers the lighting for picturing by being installed around the lens. A power supply supplies power to the digital camera and the LED lamp. The focal lens(111a) closes up the iris pattern by combining to a front side of the digital camera lens.
