There has been a problem that the distance between the three-dimensional object and the lens of the microscope is reduced, and focusing on the three-dimensional object becomes impossible. In addition, when the three-dimensional object is deformed or collapsed unless the three-dimensional object is kept horizontal, there is a problem that the three-dimensional object cannot be substantially viewed in three dimensions.

[0004] In view of the above, it is an object of the present invention to provide a three-dimensional object observation scope capable of three-dimensionally observing various three-dimensional objects with the three-dimensional objects arranged horizontally.

[0005]

According to the present invention, there is provided a table on which a three-dimensional object is mounted, imaging means for imaging the three-dimensional object mounted on the table from obliquely above, and And a housing that supports the imaging unit rotatably about an axis parallel to the table surface, and that the imaging unit is rotated to change an imaging angle. .

[0006] According to the above arrangement, the three-dimensional object is imaged from above the three-dimensional object placed horizontally on the table by changing the imaging angle of the imaging means. Therefore, regardless of the form of the three-dimensional object, the three-dimensional object can be easily and quickly three-dimensionally observed throughout.
