Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inverted microscope, for example, and more particularly to an inverted microscope fall prevention mechanism for realizing stable observation.

[0002]

2. Description of the Related Art Generally, in an inverted microscope, an illuminating optical system is provided on the inverted microscope body via a support so that when the inverted microscope body is installed on a setting part such as a desk or a surface plate, various types of illumination optical systems are installed. Fall prevention measures have been taken.

Conventionally, as this type of fall prevention means, as shown in FIGS. 10 and 11, an extending portion extending from both sides behind the inverted microscope body 3 in which the lens barrel 1 and the objective lens revolver 2 are provided. 3a and 3b are provided, and the extending portion 3a,
3b and a bottom surface of the inverted microscope main body 3 on the front side, a plurality of leg portions 4 using elastic members such as rubber so as to withstand the fall.
Are provided at predetermined intervals. As a result, the inverted microscope main body 3 is supported on the mounting portion 5 at a plurality of points by the plurality of leg portions 4 by mounting the plurality of leg portions 4 on the mounting portion 5 such as a surface plate. Prevents the fall.

Such an inverted microscope is provided with a focusing handle 6 and an output port 7 for external output corresponding to the objective lens revolver 2, and outputs observation data acquired by using this output port 7 to the outside. There are such usage patterns.
As one of such usage forms, for example, an optical splitter 8 is attached to the output port 7 as shown in FIG. 12, and the split output of the optical splitter 8 is connected to a monitor 8 as an external device.
It is possible to attach a and a camera 8b and output the observation light split by the light splitter 8 to the monitor 8a and the camera 8b, respectively.

However, in the above inverted microscope, an optical splitter 8 is attached to the output port 7 of the inverted microscope, for example, a monitor 8a.
Also, when the camera 8b is attached to the light splitter 8, the camera 8b (or the monitor 8a) comes into contact with the extending portion 3a of the inverted microscope body 3 as shown in FIG. Is. Also, the camera 8b
It is conceivable to arrange the (or monitor 8a) in the upward direction where the stage 9 of the inverted microscope main body 3 where the extending portion 3a does not exist is present, but this stage 9 becomes an obstacle and its mounting arrangement is difficult.

Therefore, when such a monitor 8a and camera 8b are used at the same time, the output port 7 and the optical splitter 8 are used.
There is a method of mounting and disposing a spacer member (not shown) between and so as not to interfere with the extending portion 3a of the inverted microscope body 3.

However, the above method has a drawback that the optical characteristic is deteriorated by the extension of the optical path length by the amount of the spacer member (not shown), and thus the observation accuracy is deteriorated.

Further, this method has a problem that the monitor 8a or the camera 8b is largely protruded from the side portion of the inverted microscope main body 3 to restrict the use of the peripheral portion of the inverted microscope main body.

[0009]

As described above, the conventional tip-over preventing means for the inverted microscope has a drawback that the usage pattern is restricted.

The present invention has been made in view of the above circumstances, and provides an inverted microscope fall prevention mechanism capable of contributing to diversification of usage forms while realizing stable installation with a simple structure. The purpose is to do.

[0011]

The present invention is to be detachably provided in an inverted microscope main body, and has an extending portion extending from a setting portion of the inverted microscope main body and having a leg portion at a tip end portion thereof. The inverted microscope fall prevention mechanism was provided with the formed fall prevention member.

When detached from the inverted microscope body,
The peripheral part of the inverted microscope body is opened so that it can be used.

As a result, it is possible to prevent the inverted microscope body from toppling over, and at the same time, it is possible to take measures such as assembling external equipment according to the usage pattern of the inverted microscope main body, thereby satisfying the diversification of usage patterns. It will be possible.

Further, according to the present invention, the angle is freely adjustable on the inverted microscope body, and an extension portion extending from the installation portion of the inverted microscope body and having a leg portion at the tip is formed. An inverted microscope fall prevention mechanism was configured with a fall prevention member.

According to the above structure, the fall prevention member has a function of preventing the fall of the inverted microscope body when the extended portion is attached to the inverted microscope body by extending the extending portion from the installation portion of the inverted microscope body. As a result, the protrusion angle of the extended portion is adjusted to open the predetermined portion of the peripheral portion of the inverted microscope body so that it can be used. As a result, it is possible to prevent the inverted microscope body from falling over, and it is possible to deal with the installation of external devices according to the usage pattern of the inverted microscope body, and it is possible to satisfy the diversification of usage patterns. .

Further, the present invention controls the first position accommodated in the inverted microscope main body and the second position extended from the installation portion of the inverted microscope main body, and has a leg portion at the tip. The inverted microscope fall prevention mechanism is provided with the fall prevention member having the extending portion.

According to the above structure, the fall prevention member functions to prevent the inverted microscope body from falling when the extension portion is located at the second position extended from the installation portion of the inverted microscope body. When the extension is located in the first position, the periphery of the inverted microscope body is open for use.

As a result, it is possible to prevent the inverted microscope body from tipping over, and it is possible to deal with the inverted microscope body by assembling external equipment according to the usage pattern, thereby satisfying the diversification of usage patterns. It will be possible.

Further, according to the present invention, the fall prevention member is provided with fixing means for fixing to the mounting portion on which the mounting portion of the inverted microscope body is mounted. According to this, it is possible to promote the certainty of the fall prevention operation of the inverted microscope body.
