Embodiment 1

[0035] first, Figure 18 An external view of a digital camera as an optical device (image pickup device) including an optical image stabilizer as a first embodiment (Embodiment 1) of the present invention is shown. Although this embodiment will describe a lens-integrated digital camera, the optical image stabilizer of this embodiment (and Embodiments 3 to 6, which will be described later) may also be provided on other cameras such as interchangeable lenses and video cameras. in camera equipment.

Abstract

The optical image stabilizer (100) includes a first movable part including a first lens (11a) having one of positive and negative optical powers, a second movable part including a second lens (11b) having the other of the optical powers, and an actuator driving the first and second movable parts in the directions opposite to each other with respect to a supporting member (13). The actuator includes a first element (110a, 110b) provided on the supporting member, a second element (16a, 16b) provided on the first movable part and facing a first face of the first element, and a third element (16c,16d) provided on the second movable part and facing a second face formed on an opposite side of the first element from the first face. The first element is one of a magnet and a coil, and the secondelement and the third element are the other of them.

Description

technical field [0001] The present invention relates to an optical image stabilizer that moves a lens in a direction different from the direction of an optical axis to stabilize an image, and optical devices such as imaging devices, interchangeable lenses, and observation devices that include the optical image stabilizer. Background technique [0002] In order to suppress image shaking due to hand shake, etc., the optical device usually includes a correction lens in a direction different from the direction of the optical axis (for example, a pitch direction (pitch direction) and a yaw direction (yaw direction) orthogonal to the optical axis. ) mobile optical image stabilizer (hereinafter simply referred to as image stabilizer). [0003] Japanese Patent Application Laid-Open No. 8-184870 discloses an image stabilizer in which the correction lens is supported by a spring and held at a neutral position in a non-image stabilized operating state, and in an image stabilized operat...
