Anti-vibration device and camera apparatus using the same
First Claim
1. An anti-vibration device comprising:
- a support member supported by a chassis; and
actuators fixed to the chassis and supporting the support member such that the support member can be driven to vibrate, wherein each of the actuators supports one end portion of a cantilever support arm, and the support member is suspended and supported by the other end portion of the support arm, and wherein the support arm is provided with a vibration detecting element which can detect vibration of the support arm which vibrates in conjunction with vibration of the chassis, and which can output a predetermined electrical signal upon detection of the vibration of the support arm.

Abstract
An anti-vibration device and a camera apparatus using the same are provided. The anti-vibration device includes an actuator that supports one end portion of a cantilever support arm. A camera module, which is a support member, is suspended and supported by the other end portion of the support arm. The support arm is provided with a vibration detecting element capable of detecting vibration of the support arm, which vibrates in conjunction with vibration of a chassis. The vibration detecting element can output a predetermined electrical signal upon detection of the vibration of the support arm. The actuator can perform control to reduce the electrical signal output by the vibration detecting element, in response to the vibration of the support arm caused by the vibration of the chassis.

12. A camera apparatus comprising:
-
a camera module including an optical device and an image pickup device;
a chassis that supports the camera module; and
actuators fixed to the chassis and supporting the camera module such that the camera module can be driven to vibrate, wherein each of the actuators includes a support arm having one end portion that is cantilever-supported, and the other end portion that suspends the camera module, wherein the support arm is provided with a vibration detecting element that detects vibration of the support arm occurring in response to vibration of the chassis, and wherein the actuator can reduce an electrical signal output by the vibration detecting element, in response to the vibration of the support arm, and the vibration of the chassis can be prevented from being transmitted to the camera module through the control of the actuator.
