Stage driving apparatus and anti-shake apparatus

An anti-shake apparatus, comprising:

• a movable unit that comprises one of an imaging device and a hand-shake correcting lens and that can be moved in a first direction perpendicular to an optical axis of a camera lens and in a second direction, being perpendicular to said optical axis and being different from said first direction, and that can be rotated around a rotation-axis parallel to said optical axis;
• a fixed unit that supports said movable unit while said movable unit is moved in said first and said second directions and rotated around said rotation-axis;
• a first driving unit that supplies a first driving force in said second direction to said movable unit;
• a second driving unit that supplies a second driving force in said first direction to said movable unit:
• a third driving unit that supplies a third driving force in said first direction to said movable unit:
• a controller that controls said first, said second and said third driving forces;
• and
• said first, said second, and said third driving units being attached to one of said movable unit and said fixed unit;
• a point on a said movable unit that receives said second driving force from said second driving unit being defined as a second driving point;
• another point on a said movable unit that receives said third driving force from said third driving unit being defined as a third driving point;
• a line segment connecting said second and said third driving points not being parallel to said first direction.
