Claims

[Scope of utility model registration request]

a first drive means for electrically driving a focusing mechanism of a microscope section; a second drive means for electrically driving a variable magnification mechanism of the microscope section; a first switch means for giving a drive control command to the first drive means; a second switch means for giving a drive control command to the second drive means; a first conversion for converting each of the commands from the first switch means and the second switch means into a serial signal code; A circuit and a second conversion circuit for reconverting a serial signal code from the conversion circuit into a parallel drive command are disposed between the drive means and the switch means, and the number of transmission lines between the two conversion circuits is reduced. A surgical microscope characterized in that it is reduced or eliminated.
