Description

  The present invention relates to a microscope stage on which an observation sample is placed and a microscope including the same.

In general, a microscope stage in which an upper plate on which an observation sample is placed is slidably brought into surface contact with a lower plate and moves relative to the lower plate is configured with a rolling guide such as a ball guide. Compared with a microscope stage, it is more stationary and often moves the upper plate relative to the lower plate by directly moving the upper plate by hand. However, in the case of low-magnification observation, there is no problem even if the structure is directly moved by hand, but in the case of performing high-magnification observation, it is difficult to move a minute distance.
Therefore, a microscope stage has been proposed in which a pair of push pins and the like are provided independently in two directions, the X direction and the Y direction, and the upper plate is relatively moved by operating the push pins with both hands or one hand ( For example, see Patent Document 1).

  However, the conventional microscope stage has the following problems. That is, in the above conventional microscope stage, when one hand is used for focusing, the observation sample must be moved with the other hand, so the observation sample is moved in a direction different from the X direction and the Y direction. Even if it is moved, since it is operated with one hand, the operation is complicated, and it is difficult to move the observation sample to a desired observation position.

  The present invention has been made in view of the above circumstances. In a microscope stage in which the upper plate is slidably in surface contact with the lower plate and moves relative to the lower plate, the relative movement of the upper plate can be easily performed. An object of the present invention is to provide a microscope stage that can be performed and a microscope including the same.

  The present invention employs the following configuration in order to solve the above problems. That is, the microscope stage of the present invention is disposed between the lower plate, the upper plate movable in two different directions with respect to the lower plate, and between the lower plate and the upper plate. An intermediate guide unit that restricts the movement of the upper plate to the first operation unit, a first operation unit that moves the upper plate in the one direction, and a second operation unit that moves the upper plate in the other direction of the two directions. And an operating handle, and a transmission mechanism for moving the upper plate in one direction or the other direction in conjunction with the first and second operating portions.

  In the microscope stage according to the present invention, the intermediate guide unit moves in one direction together with the upper plate when the transmission mechanism is interlocked with the first operation portion, and the upper plate is moved away when the transmission mechanism is interlocked with the second operation portion. Move in the direction. Therefore, since the upper plate is moved relative to the lower plate by the first and second operation units, it is easy to adjust the observation position of the observation sample.

In the microscope stage of the present invention, the operation handle is connected to an intermediate guide unit, and the transmission mechanism is a first rack provided on the lower plate, and a second rack provided on the upper plate. A first pinion provided in the first operation portion and meshing with the first rack; and a second pinion provided in the second operation portion and meshing with the second rack; The upper plate is moved together with the intermediate guide unit in the one direction by rotating the portion, and the second operation portion has a second pinion that meshes with a second rack provided on the upper plate, It is preferable that the upper plate is moved in the other direction by a rotation operation of the two operation portions.
In the microscope stage according to the present invention, the intermediate guide unit is guided in one direction together with the upper plate by the first rack meshing with the first pinion by rotating the first operation unit, and the second operation unit is rotated by rotating the second operation unit. The upper plate is guided in the other direction by the second rack meshing with the second pinion. At this time, the operation handle moves in one direction together with the intermediate guide unit.

Further, in the microscope stage of the present invention, the transmission mechanism has a long hole drilled so as to extend in the one direction in the lower plate, and the operation handle is inserted into the long hole, It is preferable that the operation handle is rotatable in the one direction along the elongated hole in a state where the pinions are engaged with the first rack and the second rack.
In the microscope stage according to the present invention, when the first operation portion is rotated, the operation handle is moved in one direction along the elongated hole by the first rack meshing with the first pinion.

Yes.
The transmission mechanism described above includes the Y rack (first rack) 25 provided in the intermediate guide unit 73, the X rack (second rack) 91 provided on the upper plate 74, and the Y handle (first rack) of the XY handle 72. A Y pinion (first pinion) 57 provided on the operation unit 103 and meshes with the Y rack 25, and an X pinion provided on the X handle (second operation unit) 102 of the XY handle 72 and meshes with the X rack 91 ( 2nd pinion) 52.

The XY handle mounting hole 81 has an inner diameter that is substantially the same as the outer diameter of the Y handle (first operation unit) 103, and the Y handle (first operation unit) 103 can be rotated about the central axis. Has been.
The pin insertion hole 82 is a long hole formed so that the long axis direction is parallel to the X axis, and the length in the long axis direction is equal to the outer diameter of the Y direction movement restriction pin (movement restriction member) 94. This is substantially equal to the sum of the intermediate guide unit 73 and the movable distance in the X-axis direction.
The intermediate guide unit 73 is provided with a Y rack (first rack) 25 at one corner of the lower surface. The Y rack (first rack) 25 is slidably contacted with the Y rack sliding groove 83.

The upper plate 74 has an X rack storage groove 92 in which an X rack (second rack) 91 is slidably stored in the Y direction on the right front side, and covers the X rack storage groove (mounting groove) 92. X rack storage lid 93 is provided.
The X rack 91 is provided with a Y-direction movement restriction pin 94 that protrudes downward.
The length of the X rack storage groove 92 in the Y axis direction is the length of the X rack 91 in the Y axis direction, the outer diameter of the X pinion (second pinion) 52 of the XY handle 72, and the movable distance of the intermediate guide unit 73. It is formed so as to be almost equal to the sum of.

The Y handle 103 includes a shaft portion 115, a Y pinion 57, and an operation knob 58.

Next, a method for operating a microscope including the microscope stage 70 having the above-described configuration will be described. First, similarly to the above-described first embodiment, the observation sample S is irradiated with illumination light, and the XY handle 72 is appropriately rotated to move the observation sample S to a desired observation position.
Here, when the operation knob 58 is rotated clockwise (counterclockwise) when viewed from above, the Y pinion 57 and the Y rack 25 are engaged with each other, so that the Y rack 25 slides inside the Y rack sliding groove 83. The Y key 33 slides inside the Y groove 23 as it moves. As a result, the upper plate 74 and the intermediate guide unit 73 move in the + Y (−Y) direction. At this time, the Y-direction movement restricting pin 94 is inserted into the pin insertion hole 82 of the lower plate 71 and the X rack 91 is restricted from moving in the Y direction. The storage groove 92 moves integrally with the upper plate 74. Therefore, even if the intermediate guide unit 73 and the upper plate 74 move in the Y direction, the X rack 91 and the X pinion 52 are stationary and maintain the meshing state.
Further, when the operation knob 53 is rotated clockwise (counterclockwise) when viewed from above, the X pinion (second pinion) 52 and the X rack (second rack) 91 are engaged with each other. Slide inside the X groove 37. As a result, the upper plate 74 moves in the + X (−X) direction.
In this way, the upper plate 74 slides relative to the lower plate 71 in the X-axis direction and the Y-axis direction, and the observation site of the observation sample S is set to a desired position.

  The microscope stage 70 configured as described above has the same operations and effects as the first embodiment described above, but the XY handle 72 rotates the X handle 102 and the Y handle 103 appropriately. Even if the upper plate 74 is slid with respect to the lower plate 71, it does not move with respect to the lower plate 71. Thereby, the observer can always observe the observation sample S in the same posture. Therefore, it is possible to provide the XY handle 72 at a position where it can be most easily operated.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, in the above embodiment, when the X key and the X groove are slidably fitted, the upper plate can move relative to the intermediate guide unit in the X-axis direction. The intermediate guide unit can be moved in the Y-axis direction relative to the lower plate by being slidably fitted, but rolling using other linear guide structures, for example, balls and rollers The straight guide structure may be used.

In the second embodiment, the X rack is slidable along the X rack storage groove formed in the upper plate. However, as described above, other linear guide structures may be used. Further, a rolling guide structure using a ball and a roller may be used.
Also, even if the sliding structure of the Y-direction movement restricting pin provided in the X rack and the pin insertion hole formed in the lower plate is also a sliding linear guide structure, the linear movement of the rolling using the ball and the roller A guide structure may be used.

Moreover, although it does not describe about the detachment | floating and floating of an upper board, these are suppressed by comprising a retainer between X key and a lower board, and comprising a retainer between Y key and an upper board. be able to.
Although lubrication in sliding between each key and each groove is not described, it is easily thought that the movement becomes smooth and light by applying a general lubricant.
Moreover, although the arrangement position of the XY handle 18 is the right front as viewed from the observer, it may be the left front, the right back, the left back, or another place.

It is a front view which shows the microscope in the 1st Embodiment of this invention. FIG. 2 is a plan view showing the microscope stage of FIG.
