Abstract
The present invention relates to an optical instrument such as an optical axis deflecting device or an image stabilizing device having an optical member supported for rotation about a predetermined axis and rotated about the predetermined axis to thereby deflect the optical axis of passing light, moving means adapted to move in a direction along a plane inclined by a predetermined angle from a plane perpendicular to the predetermined axis to thereby rotate the optical member about the predetermined axis, and driving means for driving the moving means. With such construction, a driving force generated by the driving means acts on that portion of the optical member which is far from the rotational shaft thereof and as a result, a driving torque for driving the optical member can be enhanced without causing the bulkiness and higher cost of the device and an increase in consumed electric power.
