Abstract:
1. An image stabilizer comprising: a pair of first parallel guide rods which are mounted to a stationary member and extend in a first direction; a first moving stage which is supported by said pair of first parallel guide rods to be freely movable in said first direction; a pair of second parallel guide rods which are mounted to said first moving stage to extend in a second direction orthogonal to said first direction; a second moving stage which holds an image-stabilizing optical element and is supported by said pair of second parallel guide rods to be freely movable in said second direction; a first biasing device which biases said first moving stage in one of forward and reverse directions in said first direction; a second biasing device which biases said second moving stage in one of forward and reverse directions in said second direction; a first driving device which drives said first moving stage in said first direction against a biasing force of said first biasing device; and a second driving device which drives said second moving stage in said second direction against a biasing force of said second biasing device, wherein said pair of first parallel guide rods and said pair of second parallel guide rods lie in a common plane orthogonal to an optical axis.
