Anti-shake apparatus
First Claim
1. 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 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;
a fixed unit that slidably supports said movable unit in both said first and second directions; and
a signal-processing unit;
one of said movable unit and said fixed unit having a magnetic-field change-detecting unit which has a horizontal magnetic-field change-detecting element for detecting a position of said movable unit in said first direction as a first location, and a vertical magnetic-field change-detecting element for detecting a position of said movable unit in said second direction as a second location;
said signal-processing unit outputting a first detected-position signal, which specifies said first location on the basis of output signals of said horizontal magnetic-field change-detecting element, and outputting a second detected-position signal, which specifies said second location on the basis of output signals of said vertical magnetic-field change-detecting element, and having a common input circuit which supplies electrical power to input terminals of said horizontal and vertical magnetic-field change-detecting elements.

Abstract
An anti-shake apparatus of a photographing apparatus comprises a movable unit, a fixed unit, and a signal-processing unit. The movable unit has an imaging device and is movable in first and second directions. The fixed unit slidably supports the movable unit in both the first and second directions. The movable unit has a horizontal magnetic-field change-detecting element for detecting a first location, and a vertical magnetic-field change-detecting element for detecting a second location. The signal-processing unit outputs a first detected-position signal, which specifies the first location on the basis of output signals of the horizontal magnetic-field change-detecting element, and outputs a second detected-position signal, which specifies the second location on the basis of output signals of the vertical magnetic-field change-detecting element. Further, the signal-processing unit has a common input circuit which supplies electrical power to the input terminals of the horizontal and vertical magnetic-field change-detecting elements.
