A surgical electronic microscope device (10) includes a microscope unit (110) and a support unit (120) that supports the microscope unit (110). The microscope unit (110) images an operative site of a patient (330) on an operating table (340), and outputs an image signal. The support unit (120) includes a prop unit (290c). The prop unit (290c) supports a second arm (290b) rotatably around an axis (05). The second arm (290b) supports a first arm (290a) rotatably around an axis (04). The first arm (290a) supports the microscope unit (110). Pivoting the second arm (290b) on the axis (05) while keeping the first arm (290a) substantially level makes it possible to change a height of the microscope unit (110). A length (V) of the second arm (290b) is greater than a length (H) of the first arm (290a). Accordingly, a movable range of the microscope unit (110) in a vertical direction is wide. Both an operation performed by a surgeon at a standing position and an operation performed by a surgeon at a seated position can be therefore covered.
