Abstract
PURPOSE:To make a large extra space ahead of a reflecting mirror unnecessary and to miniaturize a camera by turning the reflecting mirror centering around a horizontal axis line while sliding it in a longitudinal direction and vertically moving the tip of the reflecting mirror at the time of descending the reflecting mirror. CONSTITUTION:A reflecting mirror carrying member 5 is supported on a fixed frame member 1 through supporting mechanism set on the member 5 and the member 1, so that it can be turned and moved back and forth with the supporting mechanism. Namely, when a driving member 2 is turned clockwise centering around a shaft, the back end of the reflecting mirror carrying member 5 is turned clockwise along a cam groove la and descends and the tip is turned clockwise centering around a pin 8 and ascends. Since the cam groove la is not a circular arc with the pin 8 as the center of curvature, the pin 8 relatively moves toward the tip side of a long groove 5b in long groove 5b with the turning and ascending of the tip of the member 5. Therefore, the moving locus of the tip of the reflecting mirror 4 becomes a line L vertically drawn upward from the position of the lowest point P. Thus, the space ahead of the reflecting mirror can be made smaller and the camera can be miniaturized.
