Patent ID: 7477291

Claim:
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 that has a position-detecting coil, and that can be moved in first and second directions, said first direction being perpendicular to an optical axis of a camera lens of said photographing apparatus, and said second direction being perpendicular to said optical axis and said first direction; and a fixed unit that slidably supports said movable unit in both said first and second directions, and that has a magnetic-field change-detecting unit; said magnetic-field change-detecting unit having a horizontal magnetic-field change-detecting element which is used for detecting a position of said movable unit in said first direction, as a first location, and a vertical magnetic-field change-detecting element which is used for detecting a position of said movable unit in said second direction, as a second location; said position-detecting coil being a magnetic-field generating apparatus which is used for detecting said first and second locations, and having first and second position-detecting areas; said first position-detecting area having first and second horizontal position-detecting segments; said second position-detecting area having first and second vertical position-detecting segments; said first and second horizontal position-detecting segments being parts of said position-detecting coil, and facing said horizontal magnetic-field change-detecting element, and being parallel to said second direction; a direction of the current through said first horizontal position-detecting segment being opposite to a direction of the current through said second horizontal position-detecting segment; said first and second vertical position-detecting segments being parts of said position-detecting coil, and facing said vertical magnetic-field change-detecting element, and being parallel to said first direction; and a direction of the current through said first vertical position-detecting segment being opposite to a direction of the current through said second vertical position-detecting segment.
