Abstract

The invention provides an optical unit with a shake correction function, which enables a movable body to rotate, reduces the spring constant of a flexible printed circuit board connected with the movable body, and reduces the configuration space of the flexible printed circuit board. An optical unit (1) with a shake correction function performs shake correction by rotating a movable body (10) around an optical axis L, an X axis, and a Y axis. A flexible printed circuit board (6) connected to a movable body is provided with a first branch portion (6A), a second branch portion (6B), and a lead-out portion (6C) connected to the ends of the first branch portion and the second branch portion in the + X direction. The first branch portion and the second branch portion are each provided with a planar portion (610) bent in a virtual plane (P) along the XY plane, and a meandering portion (620) bent from the planar portion in the optical axis L direction, meandering in the X-axis direction, and extending in the Y-axis direction. The flat portion (610) and the serpentine portion overlap when viewed from the optical axis L direction.

Description

technical field [0001] The present invention relates to an optical unit with a shake correction function which makes a camera module oscillate to correct the shake. Background technique [0002] Among the optical units installed in a portable terminal or a moving body, there is an optical unit having a camera module that swings or rotates a moving body provided with a camera module in order to suppress disturbance of a captured image when the portable terminal or the moving body moves. Mechanism that corrects jitter. Patent Document 1 describes such an optical unit with a shake correction function. [0003] The optical unit with a shake correction function of Patent Document 1 includes: a movable body including an optical module; a fixed body; ) rotating swing support mechanism. The flexible printed circuit board connected to the optical module is drawn out from the movable body. [0004] In the optical unit with a shake correction function, the movable body swings while...
