PROBLEM TO BE SOLVED: To align orientation of optical axes of a finder optical system, an imaging optical system and automatic focus optical system to the optical axis of the imaging optical system by simple structure and operations. SOLUTION: An upper optical system module 101 to be constituted by assembling the imaging optical system 103, the finder optical system 102 and the automatic focus module 5 in a finder main body 85 constituters the upper side of inner structure of a camera 200, is mounted and fixed to a fixing frame 100 of the imaging optical system. The fixing frame 100 is cylindrically formed and holds a photographic lens barrel of a photographic lens. The upper optical system module 101 is mounted and fixed to the fixing frame 100 by screwing the finder main body 85b to the fixing frame 100 by a screw 100c. |
