## Abstract

The surgical microscope system includes a first binocular microscope and a first display device. The first binocular microscope includes an objective lens, a first right ocular lens which provides a first image based on a light flux transmitted through the objective lens, and a first left ocular lens which provides a second image based on a light flux transmitted through the objective lens. The first display device can be disposed opposite to or in alignment with the first binocular microscope, and includes a first right-eye image display surface for displaying the first image and a first left-eye image display surface for displaying the second image. The first display device can be reversed about a horizontal axis extending in a direction along which the first right-eye image display surface and the first left-eye image display surface are located in alignment.

## Claims

### Claim 1

A surgical microscope system, comprising:
a binocular microscope that includes an objective lens, a right ocular lens which provides a first image based on a first light flux transmitted through the objective lens, and a left ocular lens which provides a second image based on a second light flux transmitted through the objective lens; and
a display that is disposable opposite to and in alignment with the binocular microscope, includes a right-eye image display for displaying the first image and a left-eye image display for displaying the second image, and is reversible about a horizontal axis extending in a direction along which the right-eye image display and the left-eye image display are located in alignment,
wherein the binocular microscope and the display are configured to display the first image and the second image while being disposed adjacent one another and viewable in a same direction, and configured to display the first image and the second image while being disposed along a first same axis and viewable in opposite directions, and
wherein the binocular microscope and the display are configured to be independently rotatable about a second same axis with the display being rotatable about the second same axis independently of the binocular microscope.

### Claim 2 (depends on 1)

The surgical microscope system according to claim 1, further comprising a first bifurcator and a second bifurcator that bifurcate the first light flux and the second light flux transmitted through the objective lens, wherein
the first image is provided by the right ocular lens using one of first light fluxes bifurcated by the first bifurcator, and the first image is displayed on the right-eye image display based on an other one of the first light fluxes, and
the second image is provided by the left ocular lens using one of second light fluxes bifurcated by the second bifurcator, and the second image is displayed on the left-eye image display based on an other one of the second light fluxes.

### Claim 3 (depends on 2)

The surgical microscope system according to claim 2, wherein the display further comprises an image processor into which the other one of the first light fluxes bifurcated by the first bifurcator and the other one of the second light fluxes bifurcated by the second bifurcator are incident.

### Claim 4 (depends on 1)

The surgical microscope system according to claim 1, further comprising a supporting stand, wherein the binocular microscope and the display are attached to the supporting stand so that the binocular microscope and the display are movable about the supporting stand independently of each other.

### Claim 5 (depends on 4)

The surgical microscope system according to claim 4, wherein the binocular microscope is independently rotatable about at least three axes.

### Claim 6 (depends on 5)

The surgical microscope system according to claim 5, wherein the three axes are perpendicular to each other.

### Claim 7 (depends on 4)

The surgical microscope system according to claim 4, wherein the display is independently rotatable about at least three axes.

### Claim 8 (depends on 7)

The surgical microscope system according to claim 7, wherein the display is independently rotatable about six axes.

### Claim 9 (depends on 7)

The surgical microscope system according to claim 7, wherein at least two of the three axes are parallel.

### Claim 10 (depends on 1)

The surgical microscope system according to claim 1, wherein an image displayed by the display is configured to be reversed at a same position with respect to the second same axis by rotating the display 180° about a vertical axis and by reversing the display about the horizontal axis.
