<P>PROBLEM TO BE SOLVED: To provide a swing device support mechanism of a photographing optical device, capable of rotating a movable frame having a photographing optical device attached thereto with respect to a fixed frame around an axis orthogonal to an optical axis direction of a lens, with a simple configuration. <P>SOLUTION: A swing device support mechanism of a photographing optical device includes four support legs 16 including rod-like elastic members for swingably supporting a movable frame 11 mounting a lens drive device with respect to a fixed frame 12. When an optical axis of a lens is defined as a Z axis and two directions orthogonal to the Z axis are defined as X and Y axes, respectively, the four support legs 16 are mounted on the movable frame 11 and the fixed frame 12 so that one ends of the respective support legs 16 are connected to the fixed frame 12 and the other ends thereof are connected to the movable frame 11, and a circumscribed circle of a square connecting four connections on a side of the fixed frame 12 and a circumscribed circle of a square connecting four connections on a side of the movable frame 11 are coaxial and different in diameter from each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
