Patent ID: 7528862

Claim:
An anti-shake apparatus of a photographing apparatus, comprising: a movable unit that has an imaging device mounted upon a circuit board of the movable unit, 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; said movable unit having a magnetic-field change-detecting unit, and a first driving coil which is mounted upon the circuit board of the movable unit and which is used for moving said movable unit in said first direction, and a second driving coil which is mounted upon the circuit board of the movable unit and which is used for moving said movable unit in said second direction; said magnetic-field change-detecting unit having at least one horizontal magnetic-field change-detecting element which is mounted upon the circuit board of the movable unit and which is used for detecting a position of said movable unit in said first direction as a first location, and at least one vertical magnetic-field change-detecting element which is mounted upon the circuit board of the movable unit and which is used for detecting a position of said movable unit in said second direction as a second location; said horizontal magnetic-field change-detecting element being arranged inside said first driving coil; and said vertical magnetic-field change-detecting element being arranged inside said second driving coil.
