PROBLEM TO BE SOLVED: To perform adjustment with simple operation by using an adjusting member which changes the position of a visual field frame member by rotational operation and fixes the position of the visual field frame member by stopping the rotation in order to prevent an adjusting arm from protruding and occupying a large space and to prevent a visual field frame from being moved by the shock of bending the adjusting operation protrusion after the adjustment. SOLUTION: The real image finder mechanism 30 is equipped with an objective lens system 32, a focal surface 34 on which the image of a subject is formed by the system 32, an eyepiece system 36 which magnifies the image formed on the focal surface 34, the visual field frame member 40 which is formed with the visual field frame 38 for regulating the visual field of the focal surface, and a viewfinder casing 42 which holds these. The mechanism is constituted to have a supporting means 44 which supports the frame 40 movably along the focal surface with respect to the viewfinder casing 42 and the adjusting member 48 which is rotatably disposed with respect to the viewfinder casing 42, changes the position of the member 40 by the rotation and fixes the position of the member 40 by stopping the rotation.
