For example, by turning the knob 36, the intermediate plate 34 is moved to a desired position in the X-axis direction, and by turning the knob 42, the top plate 40 is
0 to a desired position in the Y-axis direction, the position of the component placed on the top plate 40 can be finely adjusted. Note that 44 is a dovetail plate fixed to the intermediate plate for guiding the top plate 40, and although not shown in the figure, the dovetail plate for guiding the intermediate plate 34 is fixed to the base plate 31.

[Problem that the invention attempts to solve]

However, in the conventional example described above, the table has a triple structure in which the top plate 40 is stacked on the intermediate plate 34 supported on the mounting plate 31. Since the table 34 is guided by the dovetail plate 44 and the like, there is a problem in that it is likely to become rattled due to wear and the like due to long-term use.

[Means for solving problems]

This idea was made to solve the above problem, and its configuration consists of two inclined side surfaces X ₁ and X ₂ perpendicular to the X axis and two inclined side surfaces perpendicular to the Y axis.

Becomes,
Thereby, it is possible to provide a fine adjustment device in the X and Y directions that can be downsized and has excellent durability.

[Example of idea]

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 is a plan view of an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line - in FIG. In the figure, 1 is a trapezoidal table that has a rectangular planar shape and has inclined side surfaces X ₁ , X ₂ perpendicular to the X-axis and inclined side surfaces Y ₁ , Y ₂ perpendicular to the Y-axis formed on its circumferential side. .

Reference numeral 2 denotes a base plate having an upper surface 2a on which the table 1 can slide; and 3 a support frame body having a space 4 in the center capable of accommodating the table 1, which is fixed to the base plate 2.

5 has a slope 5a that comes into contact with the slope side surface _X1 ,
and a guide hole 3a bored in the frame 3 along the X axis.
It is a cylindrical piece that is fitted into the cylindrical piece and is slidable in the X-axis direction, and is always urged toward the table 1 by a spring 6 inserted into a blind hole 7b provided at the center of the shaft. Even with piece 5, spring 6, etc.,
It constitutes a biasing means for pressing the table 1 toward the _X2 side in the X-axis direction.

On the other hand, 7 has a slope 7a that contacts the slope side surface _X2 , and a guide hole 3 bored in the frame 3 along the X axis.
It is a cylindrical piece that is fitted into the shaft and slidable in the X-axis direction, and a ball 8 is inserted into a blind hole 7b provided at the shaft center. Reference numeral 9 has a knob 9a, which is a fine adjustment screw screwed onto a female thread provided on the wall 3c of the frame 3, and the tip of which is in contact with the ball 8. These screws 9, pieces 7, etc. constitute screw means for adjusting the position of the table 1 in the X-axis direction against the urging force of the spring against the table 1.

Although the cross-section in the X-axis direction (-cross-section) has been explained above, the same applies to the cross _- section in _the Y-axis direction. A screw means is provided for adjusting the position of the table 1 in the Y-axis direction against the biasing force of the biasing means.
Since it is the same as that explained in the axial cross section,
Detailed explanation will be omitted. It should be noted that each member related to the Y-axis direction cross section (not shown) corresponds to each member related to the X-axis direction cross section, with a dash attached to the reference numeral.

In FIG. 2, numeral 10 is a nylon piece for preventing screw backlash.

The operation of this embodiment having the above configuration will be explained.

Now, for example, if you turn one knob 9a to the right,
The fine adjustment screw 9 moves forward, the piece 7 is pushed through the ball 8, and the table 1 moves forward in the X-axis direction against the urging force of the spring 6. At that time, since both sides X ₁ and X ₂ of the table 1 are sloped, a downward force is applied to each side,
The table 1 moves forward while slidingly contacting the upper surface 2a of the base plate 2 without floating. Also, at that time, Y
The urging force of the spring 6' is also applied to the table 1 in the axial direction, and the inclined side surfaces Y ₁ and Y ₂ are pressed between the slope 5a' of the piece 5' and the slope 7a' of the piece 7', so that the table 1 can move forward without leaning.

If you turn knob 9a counterclockwise, contrary to the above,
The adjustment screw 9 moves backward, and the table 1 is moved by the spring 6.
It moves backward in the X-axis direction due to the urging force of.

Similarly, when the other knob 9a' is turned to the right, the table 1 moves forward in the Y-axis direction, and conversely, when turned to the left, the table 1 moves backward in the Y-axis direction.

Even when both knobs 9a and 9a' are turned at the same time, a force is always acting between pieces 5 and 7 and between pieces 5' and 7' to press against table 1. is guided by these pieces,
The table itself moves in the direction combined with the X-axis direction and the Y-axis direction without rotating.

Figure 3 shows the XY table described above in the microscope 11.
2 is a perspective view showing an example in which the support frame 3 of the table 1 is applied to the field of view adjustment, and the support frame 3 of the table 1 is
is fixed, and an observation object 15 placed on a stand is observed with the microscope 11.The lens barrel 16 of the microscope is inserted into a hole provided in the table 1 and fixed, and the movement range of the lens barrel is also set on the base plate 2. Make an insertion hole large enough to avoid interference. Then, while looking through the eyepiece 17, turn the knobs 9a and 9.
By turning a', the objective lens 18 can be slightly moved in the X and Y directions to bring the object 15 into the optimum field of view.
