Anti-shake apparatus for correcting hand shake effect through first and second drive coil units

An anti-shake apparatus of a photographing apparatus, comprising:

• a movable unit that has one of an imaging device and a hand-shake correcting lens, and has a first coil unit having a first driving coil and a first position-detecting coil, and has a second coil unit having a second driving coil and a second position-detecting coil, and is movable in a first direction and a second direction;
• and
• a fixed unit that has a first permanent magnet and a second permanent magnet;
• said first direction being perpendicular to an optical axis of a camera lens of said photographing apparatus;
• said second direction being perpendicular to said optical axis and said first direction;
• said first driving coil and said first permanent magnet being used for moving said movable unit in said first direction;
• said second driving coil and said second permanent magnet being used for moving said movable unit in said second direction;
• said first position-detecting coil and said first permanent magnet being used for detecting a first location in said first direction of said movable unit;
• and
• said second position-detecting coil and said second permanent magnet being used for detecting a second location in said second direction of said movable unit.
