DRIVE DEVICE

1 . A drive device comprising:

a movable part that is swingable relative to a fixed part;

a first drive part that drives said movable part in a first direction; and

a second drive part that drives said movable part in a direction opposite to the first direction;

said fixed part having bumpers which are struck by said movable part;

said first and second drive parts simultaneously driving said movable part so as to strike the bumpers.

2 . The drive device according to claim 1 , wherein said movable part is divided into a first portion and a second portion by a surface which is parallel to the first direction and passes through the center of mass of said movable part;

wherein said first drive part applies force on the first portion, and said second drive part applies force on the second portion.

3 . The drive device according to claim 1 further comprising a third drive part that fixes said movable part relative to said fixed part so that said movable part does not move in a second direction, and is isolated from the first direction, wherein said third drive part holds said movable part when said first and second drive parts drive said movable part.

4 . The drive device according to claim 1 , wherein said first and second drive parts move said movable part so as to reciprocate along the first direction.

5 . An image-capturing device comprising:

a drive device having a movable part that is swingable relative to a fixed part, a first drive part that drives said movable part in a first direction, and a second drive part that drives said movable part in a direction opposite the first direction, said fixed part having bumpers which are struck by said movable part, said first and second drive parts driving said movable part so as to strike the bumpers simultaneously; and

said fixed part holding an imaging sensor.

6 . The image-capturing device according to claim 5 , wherein said drive part may drive said movable part in a second direction, isolated from the first direction on the imaging surface of the imaging sensor, and wherein said drive part is a shake-correction part which corrects the shake of said image sensor by driving said movable part in the first and second directions within a shake-correction area,

wherein said fixed part is provided outside the shake-correction area, and

wherein said movable part strikes said fixed part beyond the shake-correction area.

7 . The image-capturing device according to claim 5 , wherein said first and second drive parts driving said movable part so as to holds the center of the movement range of said movable part before said first and second drive parts simultaneously driving said movable part so as to strike the bumpers.

8 . The image-capturing device according to claim 5 , wherein an imaging area of the imaging sensor is covered by a covering part.
