[0007]

The microscope gantry 101
Is provided with the reflection mirror 182 constituting the transmission illumination device 180 on the gantry base 110, so that the position of the stage 111 on which the sample 113 is placed is higher than that of the microscope gantry without the transmission illumination device 180, and the focus adjustment is performed. Each time the focusing knob 1 is higher than the stage 111
40 has to be operated, and there is a problem that operability is poor.

In particular, when performing microscopic observation for a long time, the hand must be extended obliquely each time focusing is performed, and the degree of fatigue increases.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a microscope mount having excellent operability.

[0010]

According to a first aspect of the present invention, there is provided a pedestal base having a stage on which a sample is mounted, and a vertical support fixed to the pedestal base. , Is provided movably along the support portion,
A microscope supporting portion to which a microscope main body can be attached, a first focusing knob provided on the column and moving the microscope supporting portion, and a second focusing knob provided on the gantry base and moving the microscope supporting portion A focusing movement mechanism provided between one of the first focusing knob and the second focusing knob and the microscope support; and the first focusing knob and the second focusing knob And interlocking means for interlocking and rotating.

Since it is not necessary to extend the hand diagonally each time focusing is performed, and the focusing can be performed only by operating the second focusing knob provided on the base of the gantry, the operability in microscopic observation is improved.

According to a second aspect of the present invention, in the microscope mount of the first aspect, the interlocking means includes a first belt wheel provided on a rotation shaft of the first focusing knob, It is characterized by comprising a second belt wheel provided on a rotating shaft, and a belt provided between the first belt wheel and the second belt wheel.

[0013] Since the belt is used, it is inexpensive, quiet, and can absorb the roundness between the rotating shafts.

According to a third aspect of the present invention, in the microscope mount of the first aspect, a diameter of the first belt wheel and a diameter of the second belt wheel are different.

For example, by making the diameter of the first pulley larger than the diameter of the second pulley and reducing the amount of rotation of the first focusing knob with respect to the second focusing knob, one rotation of the second focusing knob can be performed. The amount of movement of the microscope body per hit can be reduced, and accurate focusing can be easily performed.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing a gantry for a microscope according to an embodiment of the present invention.

The microscope gantry 1 includes a gantry base 10, a column 20, a mount (microscope support) 30, a first focusing knob 40, a second focusing knob 50, and a transmission illumination device 80.
And

On the upper surface of the gantry base 10, a transparent stage 11 for mounting the sample 13 is provided.

The column 20 is vertically fixed to the upper surface of the base 10.

A microscope main body 90 is mounted on a mount section 30 which can move up and down along the column section 20.

The first focusing knob 40 is provided substantially at the center of the column 20 in the height direction.

The second focusing knob 50 is provided on both side surfaces of the gantry base 10. Note that hand rests 12 for the observer to place their hands on are provided on the upper sides (near the stage 11) of both side surfaces of the gantry base 10.

FIG. 2 is a sectional view taken along the line II-II of FIG.

A rack 32 is provided on the mount 30 via a guide 31.

The guide portion 31 is formed with a protrusion 33 which engages with the guide groove 21 extending in the vertical direction of the support portion 20.

The first focusing knob 40 is provided on both sides of the column 20, and a rotation shaft 41 of the first focusing knob 40 is provided with a pinion 42 that meshes with the rack 32. A pulley (first belt wheel) 43 is provided on the rotating shaft 41.

The focus moving mechanism 60 is constituted by the rack 32 and the pinion 42.

FIG. 3 is a view for explaining the second focusing knob.

The second focusing knobs 50 are provided on both sides of the gantry base 10.

A pulley (second belt wheel) 52 is provided on a rotating shaft 51 of the second focusing knob 50, and a belt 53 is stretched between the pulley 52 and the pulley 43 (see FIG. 2). , The second focusing knob 50 rotates integrally with the first focusing knob 40.

The pulleys 43 and 52 and the belt 53 constitute an interlocking mechanism (interlocking means) 70.

FIG. 4 is a sectional view for explaining the interlocking mechanism.

The diameter of the pulley 43 provided on the rotating shaft 41 of the first focusing knob 40 is 2d, and the diameter of the pulley 52 provided on the rotating shaft 51 of the second focusing knob 50 is d.

As a result, when the second focusing knob 50 is rotated once, the first focusing knob 40 is rotated by １ ／, and the interlocking means 70 having a speed ratio of 構成 さ れ る is formed.

FIG. 5 is a cross-sectional view illustrating a transmission illumination device.

The transmission illumination device 80 includes a lamp house 81 and a reflection mirror 82.

The lamp house 81 is provided at the rear of the pedestal base 10, and incorporates a lamp 83 such as a halogen lamp.

The reflection mirror 82 is provided in the gantry base 10, and irradiates the sample 13 with illumination light emitted from the lamp 83.

The microscope gantry of this embodiment is used as follows.

The sample 13 is placed on the stage 11.

The first focusing knob 40 provided on the support 20 is rotated to move the mount 30 along the support 20, and rough focusing on the sample 13 of the microscope main body 90 is performed.

Next, the second focusing knob 50 provided on the gantry base 10 is rotated to perform accurate focusing on the sample 13.

The belt 53 is a toothed belt, and the pulleys 43 and 52 have a groove which can be engaged with the belt teeth.

According to this embodiment, the second focusing knob 50 provided on the gantry base 10 is operated if rough focusing is performed by the first focusing knob 40 provided on the support column 20. Focus can be achieved only by using That is, it is not necessary to extend the hand diagonally upward every time focusing is performed, and operability is improved.

This is particularly effective when the microscope base 10 is provided with the transmissive illumination device 80 and the stage 11 is at a high position, and the microscope base is used.

Further, since the belt 53 is used, it is inexpensive, quiet, and can absorb deviations in the distance between the rotating shafts.

Further, since the first focusing knob 40 moves a large amount of the microscope main body 90 per rotation, the microscope main body 90 can be quickly moved to perform rough focusing.

On the other hand, the second focusing knob 50 is
Since the amount of movement per rotation is smaller than 0, the microscope main body 90 can be moved slowly to perform accurate focusing.

Therefore, quick and accurate pin alignment is possible.

Also, by using a toothed belt,
Since the slip between the pulleys 43 and 52 and the belt 53 is eliminated, the transmission efficiency is increased, the entire interlocking means can be reduced, and the first focusing knob 40 and the second focusing knob 50 can be driven synchronously.

The first focusing knob 40 and the second focusing knob 5
The speed ratio with 0 is not limited to 1/2, but may be set arbitrarily, or the speed ratio may be set to 1/1.

[0053]

As described above, according to the microscope mount of the first aspect of the present invention, the second focusing knob provided on the base of the mount without extending the hand diagonally upward each time focusing is performed. Since the focusing can be performed only by operating, the operability in microscopic observation is improved.

According to the microscope mount of the second aspect of the present invention, it is inexpensive, quiet, and can absorb irregularities in the distance between the rotating shafts.

According to the microscope mount of the third aspect of the present invention, the amount of movement of the microscope main body by the second focusing knob can be reduced, and accurate focusing can be easily performed.
