<p>PROBLEM TO BE SOLVED: To provide an image stabilization device that is structured to compensate for degradation of an observation image occurring by receiving a tremor of a monocular or binoculars, and to enable downsizing.SOLUTION: An image stabilization device is configured to: secure an outer frame of a gimbal suspension device, which comprises an inner frame having an erect prism mounted, an intermediate frame and an outer frame, in a housing of a monocular or binoculars composed of an objective lens, the erect prism and an eyepiece lens, in which the gimbal suspension device comprises two voice coil motors as means for rotating the intermediate frame rotatably mounted to the outer frame and the inner frame rotatably mounted to the intermediate frame; form a yoke plate constituting a first yoke part of the voice coil motor driving the intermediate frame into a curve surface; mount the first yoke part having a coil member of the two voice coil motors on a drive circuit substrate of the voice coil motor mounted to the intermediate frame; arrange a second yoke part having a permanent magnet so as to face the first yoke part on the drive circuit substrate; and rotate the gimbal suspension device.</p> |
