Optical unit with shake correcting function

摘要

The purpose of the present invention is to provide an optical unit with camera-shake correction function capable of minimizing the load applied to a movable element from a flexible wiring substrate even when the movable element is oscillated, in order to correct camera shake. In an optical unit provided with a camera-shake correction function, a movable element can be oscillated about an oscillation support point by actuating a drive mechanism for camera-shake correction, and camera shake can therefore be corrected. In a flexible wiring substrate drawn out from the movable element, a folded part folded along the rear end portion of the movable element in the optical axis direction is formed in a drawn-out portion from the movable element, and in the optical axis direction, the oscillation support point is positioned between the surface of the folded part that faces the end part on the other side −Y in the Y-axis direction of the rear end portion of the movable element in the optical axis direction, and the surface that faces toward the rear in the optical axis direction at a fixed part of the flexible wiring substrate with respect to a fixed body.

主权项

1. An optical unit with a shake correcting function comprising:
a movable body which holds an optical element; a fixed body which covers the movable body; a flexible wiring board which is extended from the movable body to an outer side with respect to the fixed body; a swing support point which is provided between a rear end portion in an optical axis direction of the movable body and the fixed body; and a shake correction drive mechanism which swings the movable body with the swing support point as a swing center; wherein the flexible wiring board is provided with a bent part, which is bent along the rear end portion in the optical axis direction of the movable body in a lead-out portion from the movable body, and a fixed part which is fixed to the fixed body in an extended portion from the fixed body to the outer side; and wherein the swing support point is located in the optical axis direction between a face of the bent part facing the rear end portion in the optical axis direction of the movable body and a face of the fixed part which faces a rear side in the optical axis direction; wherein the movable body comprise a rigid plate on the rear end portion in the optical axis direction; the rigid plate is supported by the fixed body through the swing support point; and the bent part is fixed to a face of the rigid plate on a rear side in the optical axis direction with an adhesive; wherein the flexible wiring board is bent only through the bent part between a connected part with the movable body and the fixed part; the flexible wiring board is provided with only one bent part; a portion between the bent part and the fixed part is extended so as to obliquely intersect the optical axis direction; the flexible wiring board is displaceable for the swing of the movable body in the portion between the bent part and the fixed part; and the swing support point is located between the bent part and the fixed part.
