Shown in. The lens barrel is composed of a middle barrel 1, an outer barrel 2, and a spring 3. The middle cylinder 1 holding the objective lens L is coupled to the outer cylinder 2 via a spring 3. When the middle cylinder 1 comes in contact with the sample, the spring 3 contracts due to the reaction force from the sample, so that the middle cylinder 1
Are stored in the outer cylinder 2. With such a safety device, the force applied to the lens barrel and the sample is reduced.

触を知らせる警報は発せられない。In the lens barrel having the safety device as described above, the observer cannot know that the lens barrel and the sample are in contact with each other. Therefore, the contact between the lens barrel and the sample must be visually determined from the operation of the middle barrel 1 and the like. Further, the microscope objective lens protection device issues an alarm when the lens barrel and an external object on the stage come into contact with each other by moving the stage during sample observation. However, even if the lens barrel comes into contact with the sample when the lens barrel moves in the optical axis direction of the objective lens, an alarm notifying the contact is not issued.

(B) is an electric circuit diagram of the present embodiment. The lens barrel in this embodiment has the same configuration as that of the lens barrel shown in FIG. 1, and therefore its description is omitted here. The same members as those shown in FIG. 1 are designated by the same reference numerals. Middle cylinder 1
A switch 4 is provided between the outer cylinder 2 and the outer cylinder 2. One cord from the switch 4 is connected to the power supply 5, and the other cord is connected to the buzzer 6.

Moves upwards. The switch 4 is deformed when sandwiched between the outer cylinder 2 and the middle cylinder 1 to close the electric circuit. This sounds the buzzer 6. The buzzer sound enables the observer to know that the lens barrel and the sample have come into contact with each other even while observing the sample. The observer can operate the microscope main body to move the position of the lens barrel so that the lens barrel and the sample do not come into contact with each other.

したことを知ることができる。When the lens barrel 10 and the sample come into contact with each other, the resistance value of the pressure sensitive sensor 7 becomes small and the warning lamp 8
Lights up. By turning on the warning lamp 8, the observer can know that the lens barrel and the sample have come into contact with each other. In the second embodiment, if a piezoelectric element that also serves as a switch and a power source is used instead of the pressure sensitive sensor 7, the power source 5 becomes unnecessary. The second embodiment can be applied to all kinds of lens barrels. Although the warning lamp 8 is arranged on the side surface of the lens barrel 10, for example, if the warning lamp is lit in the observation field of the sample by the observer, the observer can observe the sample. It is possible to know that the lens barrel has come into contact with the sample even when it is present.
