DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a configuration example of a microscope stage according to the present invention. In FIG. 1, reference numeral 11 denotes a fixing member fixed to the microscope main body. On this fixing member 11, a stage upper plate 12 is formed with a V-groove formed as a vertical guide 13 on each corresponding side portion and a ball (not shown) in the front-rear direction. To be movably fitted to. Further, a stage replacement member 14 is fitted into the upper surface of the stage upper plate 12 such that both outer portions thereof have a dovetail structure. In this case, a tenon 12a is provided on the stage upper plate 12 side, and the stage replacement member 1 is provided.
A dovetail groove 14a is provided on each of the four sides. As shown in FIGS. 2 (a) and 2 (b), the stage replacement member 14 has a flat portion 14b corresponding to the upper surface of the stage, which is formed to be thin, and has a size covering a slide movement area and a sample insertion / removal area on the stage. And the flat portion 14
A long hole 14c is provided at the center of b in the front-rear direction of the stage. Further, the surface of the stage replacement member 14 is coated with a white or black paint according to the purpose.

On the other hand, reference numeral 15 denotes a movable member which is fitted in a slide groove formed in the rear part of the stage upper plate 12 so as to be movable in the left-right direction. Is mounted, and this slide 16 can be mounted with two slide glasses. Reference numeral 17 denotes a pressing claw rotatably attached to the stage replacement member 14 at a position facing the cleanl 16.

In the microscope stage having such a configuration, the stage replacement member 14 having a thin flat portion 14b is provided on the upper surface of the stage upper plate 12 by a dovetail structure so as to be freely inserted and removed. Even if the slide glass is damaged due to the movement or replacement of the slide glass, it is not necessary to replace the entire stage upper plate, and only the stage replacement member 14 needs to be replaced, which is economically advantageous. Further, the stage upper plate 12 and the stage replacement member 14 are fixed by fitting a tenon 12a formed on both outer upper portions of the stage upper plate 12 with a dovetail groove 14a formed in the stage replacement member 14. By providing the tenon 12a at the thick portion of the stage upper plate 12 located outside the vertical guide 13, it is possible to prevent a decrease in stage strength.

In the above embodiment, the case was described in which the tenon formed on the upper outer side of both sides of the stage upper plate 12 and the dovetail groove 14a formed in the stage replacement member 14 are fixed only by fitting. In order to prevent the stage replacement member 14 from shifting in the front-rear direction when the sample is replaced, a screw insertion hole 18 is provided on one side of the stage replacement member 14 as shown in FIG. May be inserted.

A dovetail structure may be provided in which a tenon 14d that fits with the dovetail groove 12b is provided to fix the two. In this case, the flat portion 14b of the stage replacement member 14 needs to be higher than the upper surface of the stage upper plate 12 by the dimension B in order to smoothly move the sample by Kremmel. In addition, the width A of the flat portion 14b needs to be slightly larger than the width of the sample movement area.

In this embodiment, by providing the dovetail groove 12b in the thick portion of the stage upper plate 12 located outside the vertical guide 13, it is possible to prevent a decrease in stage strength.

Further, as a stage replacement member 14, FIG.
Use a thin iron member as shown in
The magnets 20 may be embedded in the upper surface of both sides of the two, and the two may be fixed by attracting the stage replacement member 14 to the magnets 20. In this case, since a flat plate is used as the stage replacement member 14, for example, if the front surface is painted black and the back surface is painted white, it is possible to exchange the front and back of the flat plate as required. Two types of use are possible.

In the present embodiment, the groove for burying the magnet 20 is provided in the stage upper plate 12 located outside the vertical guide 13.
By providing it in the thick part, the stage strength can be prevented from lowering.
