PURPOSE: A digital camera is provided to cut down the price of a digital camera by removing additional parts and to make the digital camera easy to process. CONSTITUTION: A digital camera has an opening(20a) in the front face of a case. The inner diameter of the opening is the same as the outer diameter of a fixing ledge(10a) of a lens knob. A recessed groove(20b) having inner diameter smaller than that of the opening is formed radially. The inner diameter of the recessed groove is the same as the outer diameter of a lower end portion(10b) of the lens knob. Thus, the opening and the recessed groove are formed as a concentric circle of different diameters.
