で観察できることが要望されている。[Prior art and problems to be solved by the invention] When the work performed using a stereomicroscope is precise and complicated, it is desirable for multiple people to work together, especially when performing surgery under a surgical microscope. It is desired that the surgeon and the assistant assisting the surgeon be able to observe the surgical site in the same state, that is, coaxially, with the same magnification, and with the same stereoscopic effect.

いう問題があった。By dividing the optical path after the pair of variable magnification optical systems 2 following the objective lens 1 with an optical path splitting member 3, two observers can face each other and three-dimensionally observe the surgical site in the same state. It is something. However, in this configuration, the angle formed by the observation directions between the two observers is limited to 180°, and there is a problem in that observation cannot be made at other angles.

問題もあった。Utility Model Publication No. 55-39364 as shown in (B) and (C)
There is a method described in the above publication, which uses three or more variable magnification optical systems 2 so that even if the surgeon and assistant observe from perpendicular directions, the surgeon and assistant can view the same surgical site. This allows for three-dimensional observation. However, in this configuration, since there are many variable magnification optical systems 2, it is necessary to move a large number of lenses, which makes the mechanism complicated and difficult to adjust, resulting in an increase in size, weight, and price of the microscope. There was a problem with putting it away. Another problem is that the angle between the viewing directions of two observers is limited to 90°.

ある。Furthermore, there is another structure as shown in FIG. 11, which is described in Japanese Unexamined Patent Publication No. 2-143215. This is achieved by installing an optical path splitting member 3 between a single objective lens 1 and a pair of variable magnification optical systems 2 to divide the optical path after the objective lens 1, and further adding a pair of variable magnification optical systems to the branched optical path. 2' is installed, and two observers attempt to observe the surgical site three-dimensionally.

という問題かあった。However, with this configuration, the angle formed by the observation directions between the two observers must be adjusted to a certain extent, which leads to problems such as increased size, increased weight, and increased price of the microscope. there were.
本発明は、上記問題点に鑑み、顕微鏡の大型化。In view of the above problems, the present invention aims to increase the size of the microscope.

In addition, since the optical path splitting means is placed after the single objective optical system and the single variable magnification optical system, two observers can view the object coaxially, at the same magnification,
If observation can be performed with the same three-dimensional effect, and the first and second three-dimensional observation systems provided in each optical path after the optical path splitting means can be rotated around the optical axis of each optical path, It can be observed by two observers or from any angle.

。Further, in this embodiment, the second optical path splitting section 16 is provided to separate the first optical path.
Since the optical path of the stereoscopic observation system 10 is bent to the side, the second
The space above the optical path splitter 16 can be used effectively, and the operation of the surgeon and assistant will not be hindered during surgery.
Since the distances of the surgeon and the assistant from the surgical site can be made equal, there is an advantage that the observation conditions for the surgeon and the assistant can be further made equal. In addition, according to this embodiment, the photographing device 19
The photographic lens 17 is not arranged on one optical axis of the left and right variable magnification optical system as in the conventional case, but the light of the single objective lens 1 and afocal zoom lens 2 is arranged largely on the axis. , the numerical aperture can be set to W, and it is possible to take high-speed glossy photographs and obtain high-resolution recorded images using a large amount of light. Note that this produces effects such as improved accuracy due to a large numerical aperture when a measuring device or the like is attached instead of the photographing device 19. Furthermore, the eighth
As shown in the figure, each car has a monocular viewing tube 22 containing an imaging lens 20 and an eyepiece 21.
装着すれば、単眼視であるか開口数の大きな結像レンズ
２０を用いることができ、それにより高解像な観察が可
