ABSTRACT:
An automatic microscope comprises an operating member operated electrically, and a detector for outputting an operation signal upon detecting the presence of an observer of the microscope in a predetermined range around the microscope, thereby operating the operating member. The operating member may be a shutter for opening and closing an optical path of the optical system of the microscope, an optical path switching member for switching the optical path of the optical system, a main power switch of the microscope, an auxiliary power switch of the microscope or a power switch for an illuminating light source, and the detector may be a light reflection detector including a light source and a photosensor unit for receiving the reflected light of the light emitted from the light source.
