PROBLEM TO BE SOLVED: To suppress the consumption of a battery as much as possible. SOLUTION: The binoculars with an image blur preventing device which corrects an image blur when images formed by a couple of left and right objective optical systems 11R and 11L are observed through a couple of left and right ocular optical systems 13R and 13L, has a couple of left and right correction optical systems 112R and 112L which are composed of the whole or part of the objective optical systems, a couple of left and right yaw holding frames 18R and 18L which holds the correction optical systems, a pitch holding frame 20 which supports the yaw holding frames rotatably, a main body frame 19 which supports the pitch holding frame rotatably, a yaw bridge 22 which associates the left and right yaw holding frames in a couple, and an unbalance correcting means which corrects unbalance caused by the gravitational forces of the correction optical systems. |
