Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the operation command switch 1 and the information setting input device 2 are connected to a microcomputer 3,
The microcomputer 3 is further connected to motors 5 and 6 as addressable parts and address detection devices 7 and 8. The motor 5 rotates the revolver 9 equipped with the objective lens, and the motor 6 rotates the turret 10 equipped with the aperture stop. Further, the address detection device 7
The address of the objective lens arranged on the observation optical path of the microscope, more precisely, the address of the mounting hole in which the objective lens is mounted, is detected, and the address detection device 8 is arranged on the illumination optical path of the microscope. The address of the mounting hole of the turret equipped with the aperture stop is detected.

As shown in FIG. 2, the operation command switch 1 includes a forward rotation switch 21 and a reverse rotation switch 22,
The operator presses the switch 21 or 22 to instruct whether the revolver 9 is normally rotated or reversely rotated. The information setting switch 2 is composed of a plurality of switches 31a to 36, as shown in FIG. Switch 3
1a to 31e are switches that specify the input order 1 to 5, and the switches 32a to 32e and 33a to 33e are
Switches 34a to 34e and 35a to 35e for designating the type of objective lens to be mounted are switches for designating the type of aperture stop to be mounted, and switch 36 is 3
It is a switch that determines the information specified by the switches 1 to 35.

Information of the correspondence tables 1 and 2 is stored in advance in the memory 4 connected to the microcomputer 3. Correspondence table 1 is a correspondence table as shown in FIG. 4, which shows the optimum combination of aperture stops for specific objective lenses, and correspondence table 2 is a turret from the current address to a predetermined address, as shown in FIG. It is a correspondence table showing the rotation direction and the rotation amount of the turret when rotating the.

The operation of the microscope of this embodiment is shown in FIG.
This will be described with reference to FIG. Information indicating the type of the objective lens is engraved on the outer side surface of the lens barrel of the objective lens. Similarly, in the aperture stop, on the surface of the attachment for mounting the aperture stop on the turret 9, Information indicating the type of aperture stop is engraved. First, the information setting work will be described with reference to FIG.

The addresses 41 to 45 of the revolver 9 and the addresses 51 to 55 of the turret 10 are shown in FIG.
It is assumed that the objective lens and the aperture stop as shown in are mounted. The operator turns on the information setting input device 2 and operates a key indicating information (step S1). For this operation, the objective lens located on the optical path of the microscope is now D
Assuming that the aperture diaphragm is DIC-NL with IC10 ×,
The switch 31a indicating the input order 1 is pressed, the switches 32a and 34a indicating the types of the objective lens and the aperture stop currently mounted on the optical path of the microscope are sequentially pressed, and finally the switch 36 is pressed for determination. When the switch 36 is operated, a signal indicating these pieces of information is output from the information setting input device 2 to the microcomputer 3, and the microcomputer 3 outputs the output information and the revolver 9 and the revolver 9 when this information is output. The information is stored in the memory 4 in association with the address of the turret 10 (step S2). It will be omitted because it becomes redundant below, but until the correspondence table 3 is completed, the revolver 9 and the turret are also moved so that the mounting holes and the mounting portions are shifted to the next mounting holes and the mounting portions in the order of input 2 to 5, respectively. Steps S1 to S3 are repeated while rotating 10 by 1 click. When the above input operation is completed, the correspondence table 3 shown in FIG. 7A is stored in the memory 4 (step S3). As a result, what objective lens and aperture stop are attached to the addresses of the revolver 9 and the aperture stop 10 are stored. After this setting work, the microcomputer 3 creates the correspondence table 4 shown in FIG. 7B from the information of the correspondence table 3 and the information of the correspondence table 1 and stores it in the memory 4 (step S4). . The correspondence table 4 is a correspondence table for identifying the address of the mounting portion of the turret 10 corresponding to the address of the mounting hole of the revolver 9. This completes the information setting work. The setting work is performed every time the objective lens or the aperture stop is replaced, and the sample is observed after the setting work.

The operation of the microscope at the time of observing the sample will be described with reference to FIG. The objective lens and the aperture stop are mounted and set as in the correspondence table 3. When the setting work is completed and the operation command switch 1 (hereinafter, simply referred to as switch 1) is turned on, the microcomputer 3
First, it is determined whether or not the key operation of the switch 1 is performed (step S11). Next, it is determined whether the operated key is the forward rotation key 21 or the reverse rotation key 22 (step S12). For example, if the forward rotation key 21 is operated, the microcomputer 3 outputs a command to rotate the motor 5 forward (step S13), and the motor 5 rotates forward based on this command (step S14). Similarly, when the reverse rotation key 22 is operated, the microcomputer 3
Outputs a command to rotate the motor 5 in the reverse direction (step S1
5), the motor 5 reversely rotates based on this command (step S16).

When the motor 5 rotates and the objective lens is replaced, the microcomputer 3 causes the address detecting device 7 to operate.
To detect the address of the mounting hole of the revolver 9 located on the optical path of the microscope (step S17), read the correspondence table 4 from the memory 4 (step S18), and based on the correspondence table 4 the address detected in step S17. The address of the turret 10 corresponding to the detected address is specified (step S19). Therefore, now
If the address of the revolver 9 detected now is 41, the address of the turret 10 is 5 from the correspondence table 4.
Specified as 1.

Next, the address detecting device 8 detects the address of the mounting hole of the turret 10 currently located on the optical path (step S20), and further reads the correspondence table 2 from the memory 4 (step S21), and the correspondence table. Based on 2, the rotation direction and the rotation amount of the turret 10 for rotating from the address detected in step S20 to the address specified in step S19 are specified (step S22). Now, assuming that the detected address of the turret 10 is 53, the rotation direction and the rotation amount are specified to be two times to the left from the correspondence table 2 because the address specified in step S19 is 51.

As a result of the identification, it is judged whether or not the rotation is necessary (step S23), and when the rotation is required, the microcomputer 3 rotates the turret 10 by the specified rotation direction and rotation amount. The drive command of the motor 6 is output (step S24), and the motor 6 rotates the turret 10 based on this command (step S25). If it is determined in step S23 that rotation is unnecessary, or if the turret 10 is rotated in step S25, the process waits until the next key operation is performed.

As described above, in the microscope of the embodiment, the objective lens is replaced in accordance with the operation of the operation command switch 1, and the aperture stop corresponding to the automatically replaced objective lens is replaced. In the embodiment, the aperture stop was selected and replaced so as to be suitable for the replaced objective lens, but the present invention is not limited to this. For example, as an application of the embodiment, an observation method designating means as shown by a dotted line in FIG. 1 is added, and the correspondence table 1 takes the observation method into consideration, that is, it is appropriate according to the observation method and the objective lens. By changing the aperture diaphragm so that it can be selected and selecting the aperture diaphragm according to the observation method specified by the microcomputer 3 and the objective lens on the optical path, the aperture can be changed when the objective lens is replaced in consideration of the observation method. You can also change the aperture.

Further, after the objective lens was exchanged, an appropriate aperture stop aperture was selected for the exchanged objective lens, but the address detected by the address detecting means by the microcomputer 3 and the objective lens exchange If the address of the mounting hole to be arranged next on the optical path is calculated from the direction of rotation by the rotary key operated for this purpose, the procedure of FIG. 8 can be performed based on this calculated address, and the aperture stop It is also possible to reduce the time required to replace the.

[0019]

According to the present invention, an objective lens mounted at a predetermined address position in accordance with a signal from the pointing means is arranged on the optical path of the microscope, and the objective lens mounted at the predetermined address position is arranged. Since the corresponding aperture stop is specified and the specified aperture stop is arranged on the optical path, the number of objective lenses and aperture stops may be the minimum necessary, and therefore the number of objective lenses and aperture stops to be prepared can be reduced, Also, if the same number is prepared, the sample can be observed under more combinations of conditions. Further, it is not necessary to prepare the same number of objective lenses and aperture diaphragms corresponding to each other, or to mount the corresponding objective lenses and aperture diaphragms at the same address positions of the revolver and turret, respectively. Easy to put on.
