## Abstract

An image shake correction device includes: a movable member; an imager that is fixed to the movable member; a support member that supports the movable member to be movable in a direction along a circumferential direction of a circle whose center is a center of a light receiving surface of the imager; and two movement restrictors that restrict a movement range of the movable member, each of the two movement restrictors includes a recess portion or a through-hole and an insertion member as defined herein, a shape of the recess portion or the through-hole is as defined herein, and a second diagonal line overlaps an extension line of a first diagonal line and the center of the light receiving surface overlaps a line connecting the first diagonal line and the second diagonal line as defined herein.

## Claims

### Claim 1

An image shake correction device comprising:
a movable member;
an imager that is fixed to the movable member;
a support member that supports the movable member to be movable;
two movement restrictors that restrict a movement range of the movable member;
a circuit board that has the imager mounted thereon, and is fixed to the movable member; and
two position detectors that are arranged on a rear surface of the circuit board opposite to a surface of the circuit board on which the imager is mounted to detect a position of the movable member,
wherein a line connecting the two position detectors overlaps a center of a light receiving surface of the imager as viewed in a direction perpendicular to the light receiving surface, and
wherein a first distance between the two movement restrictors in a longitudinal direction of the light receiving surface of the imager is same as a second distance between the two movement restrictors in a short direction of the light receiving surface of the imager.

### Claim 2 (depends on 1)

The image shake correction device according to claim 1,
wherein each of the first distance and the second distance is equal to or greater than 0.75 times and is equal to or less than 1.25 times a distance between the two position detectors.

### Claim 3 (depends on 1)

The image shake correction device according to claim 1,
wherein the two position detectors are arranged, in a longitudinal direction of the light receiving surface of the imager, on the rear surface of the circuit board.

### Claim 4 (depends on 2)

The image shake correction device according to claim 2,
wherein the two position detectors are arranged, in the longitudinal direction of the light receiving surface of the imager, on the rear surface of the circuit board.

### Claim 5 (depends on 1)

An imaging device comprising the image shake correction device according to claim 1.
