Abstract

An anti-vibration device of a photography device includes a movable unit and a fixed unit. The movable unit has an imaging device, and can move and rotate in a plane perpendicular to the optical axis of the photographing lens of the photographing device. The fixed unit supports the movable unit in a movable and rotatable state within a plane. The movable unit and the fixed unit have a moving device that moves and turns the movable unit. The number of points receiving the first force in the first direction by the mobile device is equal to or greater than one. The first direction is perpendicular to the optical axis. The number of points receiving the second force in the second direction by the mobile device is equal to or greater than two. The second direction is perpendicular to the optical axis and the first direction.

Description

technical field [0001] The present invention relates to an anti-shock device for a photographic device (device), and more particularly to a position detection device for a movable unit including an imaging device or the like and which can be moved to correct a hand-shake effect. Background technique [0002] An anti-vibration device for a photographic device is proposed. The anti-shake device corrects the jitter induction by moving the jitter correction lens or the imaging device on a plane perpendicular to the optical axis corresponding to the amount of jitter during imaging. [0003] Japanese Unexamined Patent Application Publication No. (KOKAI) No. 2002-229020 discloses a shockproof device for a photographing device. The anti-vibration device performs a linear movement and rotation operation of a movable unit including a hand-shake correction lens by using a magnet and a coil, and a position detection operation of the movable unit by using a hall element and a magnet.
