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.
An automatic microscope comprising:
An automatic microscope having a first optical path for observing an image of a specimen and a second optical path different from said first optical path, comprising;

The present invention relates to an automatic microscope.
2. Related Background Art
FIG. 1 is a block diagram of a first embodiment of the present invention;
FIG. 2A is a view showing the optical path switching by a mirror in a second embodiment of the present invention;
FIG. 2B is a block diagram of a second embodiment of the present invention;
Now a first embodiment of the present invention will be explained with reference to FIG. 1.
A shutter 1, constituting an operation unit 2, opens an optical path of an illuminating optical system for guiding the illuminating light to a specimen, when a current flows in a direction A, and closes said optical path when a current flows in a direction B. A reflected light sensor 3 outputs a detection signal upon detecting the presence of an observer within a predetermined detection range. A control unit 4 is composed of transistors Q1, Q2 connected to an inverter U1, and transistors Q3, Q4 connected to a buffer U2. Between the sensor 3 and the control unit 4, there is provided a switch 5, and there is branched a signal output unit 6, composed of a buffer 7 and a connector 8.
In the following there will be explained the function of the above-explained circuit.
