no. 1 Embodiment

[0116] First, refer to Figure 1 to Figure 5 , the configuration of binoculars equipped with the image stabilization device according to the first embodiment of the present invention will be described. figure 1 Indicates the three-dimensional appearance of the binoculars, figure 2 Indicates the internal three-dimensional composition, image 3 The exploded three-dimensional structure of the main part of this binocular is shown. Figure 4 express figure 1 The cross-section along the XY plane of the optical device shown constitutes, Figure 5 express image 3 The visual section along the V-V line. in addition, figure 2 , Figure 4 and Figure 5 BR and BL in are the optical axes of the right-eye and left-eye optical systems, respectively.

[0117] Such as figure 1 and figure 2 As shown, the binoculars include a pair of objective lens parts 20R, 20L and a pair of eyepiece parts 10R, 10L supported by a main body 1 of a substantially rectangular parallelepiped housing, ...

no. 2 Embodiment

[0191] Refer below Figure 10 ~ Figure 13 , the image stabilization device according to the second embodiment of the present invention will be described. In addition, regarding the same as used in the first embodiment Figure 1 to Figure 8 Components in the components that are substantially the same are given the same symbols in this embodiment, and descriptions thereof are omitted as appropriate.

[0192] In the first embodiment described above, the case where the power switch 2 for turning on the power of the main body and the manual operation unit 6 for starting and stopping the image stabilization mechanism 50 are separately provided is described. On the other hand, in this embodiment, the case where the manual operation part 16 which integrates the said power switch 2 and the manual operation part 6 is provided is demonstrated. Therefore, the binocular equipped with the image stabilization device of this embodiment is different from the figure 1 Have the same appearanc...

Abstract

The present invention discloses one kind of image stabilizer, which makes it possible to obtain excellent observation image during the whole time period from the beginning of still control to the ending of still control. One timing controller initiates the still control mechanism and one controls the blocking mechanism to release the blocking of the movable holding mechanism with some lagging to the initiation, so that excellent observation image may be obtained immediately after still control. Therefore, excellent observation image may be obtained during the whole time period from the beginning of still control to the ending of still control.

Description

technical field [0001] The present invention relates to an image stabilizing device used in an optical device to prevent blurring of an optical image caused by vibration, for example, an image stabilizing device applied to an optical device for observation such as binoculars. Background technique [0002] For example, when optical devices such as binoculars are used in places with vibration and shaking, such as moving vehicles and ships, the observed optical image will vibrate or shake, forming a state that is very difficult to observe. This is because the emission angle of the light beam from the observation object varies with respect to the optical axis of the optical device. In order to prevent such deterioration of observed images, there is known an image stabilizing optical device having an image stabilizing function (Japanese Laid-Open Patent Publication No. Sho 57-37852). This device is equipped with a mechanism for fixing the erecting prism (image stabilization mech...
