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; and

    a fixed unit that slidably supports said movable unit in both said first and second directions;

    one of said movable unit and said fixed unit having 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; and

    the application of voltage to input terminals of said horizontal magnetic-field change-detecting element and said vertical magnetic-field change-detecting element being performed during a position detecting operation of said movable unit, and being stopped at a time other than the time for said position detecting operation.
