Patent ID: 7302172

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 can be moved and rotated on a plane which is perpendicular to an optical axis of a camera lens of said photographing apparatus; and a fixed unit that supports said movable unit in a movable and rotatable situation on said plane; said movable unit and said fixed unit having a position-detecting apparatus that detects first position-information of said movable unit in a first direction being perpendicular to said optical axis, and detect second position-information of said movable unit in a second direction being perpendicular to said optical axis and said first direction; one of said movable unit and said fixed unit having an optical sensor unit that has one or more position-detecting elements which are used for detecting said first position-information, as said position-detecting apparatus, and that has two or more position-detecting elements which are used for detecting said second position-information, as said position-detecting apparatus; another of said movable unit and said fixed unit having a slit light-source unit that has one or more slit light-sources which are used for detecting said first position-information, as said position-detecting apparatus, and that has two or more slit light-sources which are used for detecting said second position-information, as said position-detecting apparatus; a number of said position-detecting elements which are used for detecting said first position-information being the same as a number of said slit light-sources which are used for detecting said first position-information; and a number of said position-detecting elements which are used for detecting said second position-information being the same as a number of said slit light-sources which are used for detecting said second position-information.
