Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a microscope stage.

<Prior Art> A plan view of a conventional stage of this type is shown in FIG. Open the specimen pressing claw 53 of the specimen holder 100 in the direction of arrow P against the spring force, slide the upper surface of the stage plate 54, and slide the slide glass.
The sample 51 is brought into contact with the sample receiving surface 52. After that, when the sample holding claw 53 is released, the claw 53 rotates in the direction opposite to the arrow P by the spring force and presses the slide glass 51 against the sample receiving surface 52. And, this kind of conventional stage has a sample holding claw 53
Was formed longer than the length of the short side of the slide glass 51.

<Problems to be solved> For pathological examinations, etc., in the case of relatively low magnification observation with an objective lens magnification of about 10 times, how to use the slide glass directly by hand on the stage surface without using the specimen moving mechanism of the microscope stage. I have something to do. At this time, when the sample holder is moved rearward to reach the position of the two-point line in the figure, the tip 53'a of the sample holding claw 53a
If the distance B'between the optical axis of the objective lens and the passing position O'of the objective lens is shorter than the short side length of the slide glass 51, the sample holding claw 53 'interferes and the entire surface of the slide glass 51 is freely moved on the upper surface of the stage 54. I can't, and I can't see the entire surface of the slide glass 51. Therefore, if the distance B'is increased, the amount of forward and backward movement of the stage 54 increases, and as a result, the microscope and the stage increase in size, and the space on the desk increases, which is inconvenient and expensive. Reference numeral 52 'in FIG. 2 is a sample holder.
The sample receiving surface when 100 is moved backward is shown. Therefore, a microscope user using the above-described method removes the sample holder from the stage and uses it. On the contrary, at high magnification, it is difficult to accurately align the sample manually.

<Means and Actions for Solving the Problem> The present invention makes it possible to slide the specimen holder on the stage surface without removing the specimen holder from the stage even if the amount of movement in the longitudinal direction of the stage is small by making the specimen holding claw shorter than the short side length of the slide glass. By directly moving the glass by hand, the entire surface of the slide glass can be moved onto the optical axis of the microscope objective lens.

〔Example〕

The present invention will be described below based on the embodiment whose plan view is shown in FIG.

The specimen holder 10 is provided with symmetrical specimen holding claws 3 and 30.
An insertion port for the slide glass 1 is formed in the front. At the bases of the pair of sample pressing claws 3, 30, a pair of sample receiving surfaces for positioning the slide glass 1 together with the inner sample receiving surfaces 2, 20 of the sample pressing claws 3, 30 and the front side surfaces of the sample pressing claws 3, 30 are provided. Two and twenty are provided. And the ends 3a, 30a
And the distance A between the sample holder 10 and the slide glass 1 is less than the length of the short side of the slide glass 1, and the sample holder claw is moved backward (in the vertical direction (Y direction) in the drawing, away from the optical axis 0). The distance B between the tips 3'a and 30'a (two-dot chain line) of the lenses 30 and 30 and the optical axis 0 of the microscope objective lens is equal to the slide glass 1
Is set to be equal to or greater than the length of the short side of.

In addition, the surface of the stage plate 4 is harder than the slide glass 1 such as ceramics so that the surface of the stage plate 4 is not scratched even if the slide glass 1 is slid on the stage plate 4 and durability is increased. Coated with a high substance.

In addition, in pathological observation, there are cases where marks are placed with red or blue ink on the location of the sample to be re-microscoped, so the color of the above-mentioned coating is white or a bright metal color so that these marks are easy to see. (For example, a whitish metallic color of aluminum, silver, chrome, nickel, etc.). Therefore, this coating also serves to make the above-mentioned marks stand out.

The reference numerals 2'and 20 'in FIG.
It shows the position of the sample receiving surface when is moved to the rear. The distance C is the distance between the sample receiving surfaces 2'and 20 'and the objective lens optical axis 0 when the sample holder 10 is moved backward, and has a relationship of C = A + B. Further, the long hole q is an opening for passing the transmitted illumination light.

With such a structure, the slide glass 1 is inserted by sliding the surface of the stage plate 4 through the slide glass insertion opening formed by symmetrically providing the specimen holding claws in front of the specimen holder 10. Contact the receiving surface 2. As a result, the slide glass 1 is positioned by the inner surfaces of the sample pressing claws 3 and 30 and the sample receiving surfaces 2'and 20 ', and is held by the sample holder 10. In practice, for example, the interval between the left and right sample pressing claws 3, 30 is configured to be slidable so as to slightly increase or decrease with the length of the long side of the slide glass 1 as the center, and the left and right sample pressing claws 3, 30 are It is constructed by biasing with springs in the directions toward each other. Therefore, slide glass 1
To hold the slide glass 1, open the left and right specimen pressing claws 3, 30 against the spring force, insert the slide glass 1, and then slide the slide glass 1
When the slide glass 1 is brought into contact with the sample receiving surfaces 2 and 20 and the hands are released from the sample pressing claws 3 and 30,
Held by 30.

The driving device for the sample holder 10 is the same as the conventional one. That is, the X-direction moving member that moves in the X-direction with respect to the stage plate 4 is mounted on the Y-direction moving member that moves in the Y-direction with respect to the stage plate 4, and the sample holder 10 is screwed onto the X-direction moving member 40. It is fixed at 40a and 40b. Therefore, the sample holder 10 itself moves on the stage plate 4 in the X and Y directions.

Now, when the sample holder 10 is moved in the Y direction and moved to the position of the chain double-dashed line in the figure (this position is the position where the sample holder is moved to the rearmost), the slide glass 1 is moved to the optical axis 0 Is located at the position passing through the center, the slide glass 1 can be manually moved on the stage plate 4 without being disturbed by the sample pressing claw 3. Since the surface of the stage plate 4 is coated with a substance having a hardness higher than that of the slide glass 1, even if the slide glass 1 is frequently slid, the surface of the stage plate 4 is not scraped.

The surface of the stage plate 4 is a slide glass 1 such as white.
Since the mark provided on is formed in a color that is easy to see, the re-microscope can be easily performed.

In the above description, the sample holding claw 3 of the sample holder 10,
Although the example in which 30 is configured symmetrically is taken as an example, the shapes of the sample pressing claws 3 and 30 do not need to be symmetrical, and in particular,
When the length, that is, the distance A is different between the left and right sample pressing claws 3, 30, the above condition is satisfied for the larger distance A.
That is, it is sufficient to satisfy the requirement that the length is not more than the length of the short side of the slide glass.

Further, the sample holder of the present invention has a structure in which the sample pressing claws 3 and 30 are both fixed, one is fixed and the other is biased to press the slide glass to the fixed side,
It does not matter which of the two structures is biased toward each other (this has already been described in detail).

Furthermore, in the above-described embodiment, the specimen holder 10 itself is
Although the one that moves on the stage plate 4 in the X direction and the Y direction has been described, the sample holder 10 moves only in the X direction and the stage plate 4 moves in the Y direction. The effect can be obtained.

(Effects of the Invention) As described above, according to the present invention, the slide glass is directly moved on the stage by hand without increasing the size of the stage and without removing the sample holder, and the entire surface of the slide glass is covered with a microscope. It can be moved on the optical axis of the objective lens.
