Problems solved by technology

[0010] However, in the assembly process of adding shake correction components, the arm portion 305a of the plate spring 305 is likely to be damaged during the assembly work. If the arm portion 305a is damaged, the lens driving device 300 may malfunction.
On the other hand, by increasing the assembly process (assembly man-hours), it is also possible to reduce the damage of the arm portion 305a, but the disadvantage is that the assembly cost of the lens driving device 300 will increase.

Abstract

The invention aims to provide a jitter correction device which is a jitter correction device of a camera, is producible at low cost without needing an assembling procedure of a lens drive device additionally, and is of a simple structure irrelevant to the size and mounting position of the lens drive device. The jitter correction device comprises a first stator (101ax) and a second stator (101ay); and a first movable part (101bx) and a second movable part (101by), which are respectively and movably supported by the first stator (101ax) and the second stator (101ay). The first stator (101ax) and the second stator (101ay) are mounted in a frame body (106) used for holding a lens drive device (104).

Description

technical field [0001] The present invention relates to a shake correction device for correcting shake generated by a lens driving device mounted in a mobile phone or the like. Background technique [0002] In recent years, various functions have been added to mobile phones, and in particular, mobile phones with cameras equipped with cameras have been widely used. Cameras installed in mobile phones have autofocus functions, and in addition to autofocus functions, camera shake correction functions are being upgraded and added. [0003] For example, by operating a lens driving device for holding a lens in a mobile phone with a camera, not only autofocus but also swinging in a direction at right angles to the optical axis of the lens can be realized, thereby realizing shake correction. [0004] Figure 6 The shake correction device 310 shown is an example of a wire suspension method in which a shake correction function is added to the lens driving device 300 . The shake corre...
