Stage apparatus and camera shake correction apparatus

A stage apparatus comprising:

• a stationary support plate;
• a magnetic force generator which is immovable relative to said stationary support plate;
• a stage member that is superimposed on said stationary support plate in a thickness direction of said stationary support plate, wherein said stage member is slidably movable relative to said stationary support plate in a plane;
• a control circuit board which is immovably provided at a lateral side of said stage member;
• an image sensor fixed to said stage member;
• and
• a first FPC board provided between said stationary support plate and said stage member, said first FPC board electrically connecting said image sensor and said control circuit board,
• wherein said stage member is provided with a cover member fixed thereto, for protecting at least a part of said first FPC board, the cover member including a first cover portion fixed to the stage member and extending in a plane of the stage member, a second cover portion comprising a front surface protective portion that extends in a plane transverse to the first cover portion and a third cover portion comprising an edge protective portion that extends in a plane transverse to the plane of the second cover portion.

A stage apparatus configured to be included in a camera having an image sensor, the stage apparatus comprising:

• an integrated movable body which is slidably movable;
• a pair of coils, both of which apply a linear driving force in one driving direction to said integrated movable body upon an electric current being passed through said pair of coils, said pair of coils being positioned in a magnetic field;
• and
• a single driver for carrying out an electric current control on said pair of coils, wherein a distance, in a direction orthogonal to said one driving direction, from a center of gravity of an said integrated movable body to the center of driving force of one of said pair of coils is longer than a distance, in the direction orthogonal to said one driving direction, from the center of gravity to the center of driving force of the other of said pair of coils, and
• wherein said stage apparatus is further provided with a driving force reducer comprising an electric resistor for reducing said driving force in an electric circuit electrically connected to said one of said pair of coils that is located at a longer distance, in the direction orthogonal to said one driving direction from the center of gravity to the center of driving force of said one of said pair of coils.
