A heliostat includes mirrors. Each mirror is supported with a frame at three points including a fulcrum and movable points. The movable points are provided with electric extendable units, respectively. The electric extendable units are separately controlled to change distances between the mirror and the frame at the movable points, thereby correcting an aberration of the mirror and always directing reflected light from the mirror toward a predetermined position.

When the compression spring is compressed due to the relative displacement of the stopper which occurs in response to the tilt angle of the arm structure, the compression spring is compressed by the small relative displacement of the stopper over its entire body in the longitudinal direction, so that a repulsive force is obtained which varies little over the entire range of the tilt angle, enabling support of the heavy object in a stable condition.

A surgical microscope system includes a camera that is rotatable around a first rotation axis and a second rotation axis, the rotation axes being orthogonal to each other, so that a photographing direction of the camera is changeable at a given position. The first rotation axis is inclined with respect to a vertical axis, and therefore, a lower end of a first member is able to be set at a height that does not interfere with the photographing direction when the camera is horizontally oriented.
