Patent ID: 8446672

Claim:
A vibration reduction apparatus comprising: a fixed portion, a moving portion having a vibration reduction optical system and which moves in a plane perpendicular to an optical axis of the vibration reduction optical system, relatively with respect to the fixed portion, a first detection portion which detects relative movement in a first direction of the moving portion and the fixed portion, a second detection portion which detects relative movement in a second direction of the moving portion and the fixed portion, a center of gravity adjusting member disposed at the moving portion such that a center of gravity position of the moving portion is positioned adjacent to a first crossing point of a first detection line extending from the center of the first detection portion along the first detection portion and a second detection line extending from the center of the second detection portion along the second detection direction, a first driving portion which moves the moving portion relative to the fixed portion in a first movement direction, and a second driving portion which moves the moving portion relative to the fixed portion in a second movement direction, wherein a first movement line extending from the center of the first driving portion along the first movement direction and a second movement line extending from the center of the second driving portion along the second movement direction do not pass through an optical center, a second crossing point of the first movement line and the second movement line is separated by a predetermined distance with respect to the center of gravity of an optical center along a first line, the first driving portion is disposed between the first detection portion and the center of gravity adjusting member, the second driving portion is disposed between the second detection portion and the center of gravity adjusting member, and a part of the first driving portion and a part of the second driving portion are disposed on a second line perpendicular to the first line, with the vibration reduction optical system interposed therebetween.
