Patent ID: 7355630

Claim:
An anti-shake apparatus of a photographing apparatus, comprising: a movable unit that has an imaging device and a position-detecting magnet, and can be moved in a first direction and a second direction; and a fixed unit that has a magnetic-field change-detecting unit; 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 position-detecting magnet being used for detecting a first location in said first direction of said movable unit and a second location in said second direction of said movable unit, and having a front-surface which faces said magnetic-field change-detecting unit; said magnetic-field change-detecting unit having first and second horizontal magnetic-field change-detecting elements which are used for detecting said first location, and having first and second vertical magnetic-field change-detecting elements which are used for detecting said second location, and facing said position-detecting magnet; and said optical axis passing through a center area of said front-surface of said position-detecting magnet, when a center area of said imaging device is located on said optical axis.
