发明名称 LENS BARREL AND OPTICAL DEVICE INCLUDING IMAGE BLUR CORRECTION DEVICE
摘要 PROBLEM TO BE SOLVED: To achieve workability improvement and reliability enhancement of assembling an image blur correction device configured to dispose a magnet, a coil, a flexible printed circuit board, and a yoke in sequence in the direction of an optical axis and to dispose a hall element in a hole of the coil.SOLUTION: The image blur correction device comprises: a driver part that is composed of the magnet, the coil, and a magnetic member; the hall element that serves as a position detection part; a bobbin that supports the coil to be electrically connected to the coil; and the flexible printed circuit board that is electrically connected to the bobbin and the hall element. The bobbin includes: a holding part that positions the coil and the hall element at a plane orthogonal to the optical axis; a coil reception surface that regulates the position of the coil in the direction of the optical axis; a flexible printed circuit (FPC) reception surface that regulates the position of the FPC in the optical axis direction; terminals that are electrically connected to the coil by winding coil wires therearound; and a terminal stage that attaches the terminals. The holding part is engaged with the hall element by a positioning shape provided inside the holding part and is of a convex shape allowing the external shape to be engaged with the hole of the coil, and the hall element is disposed in the hole of the coil.
