Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a microscope gantry, and more particularly to a microscope gantry used when observing and manipulating a sample like a stereomicroscope. In particular, the gantry base has a transmission illumination device, and the gantry base is thick. This invention is effective for a microscope mount having a high position.
[0002]
[Prior art]
An example of this type of conventional apparatus is shown in FIG. In FIG. 4, a column 102 is fixed to the gantry base 101. The microscope 104 is attached to the mount unit 103. A pinion gear (not shown) is formed on the shaft (not shown) of the focusing knob 105 rotatably provided on the mount portion 103 and meshes with a rack (not shown) fixed to the column 102. Accordingly, by rotating the focusing knob 105 and moving the mount unit 103 up and down, the sample on the transparent sample stage 106 can be focused.
[0003]
A lamp house 107 is provided behind the gantry base 101. Illumination light emitted from a lamp (not shown) in the lamp house is deflected by approximately 90 degrees by the reflecting mirror 108 in the gantry base 101, and the transparent sample stage 106 is moved. Transmit through and illuminate the sample. When the knob 109 is rotated, the angle of the reflection mirror 108 changes, and the illumination state changes.
[0004]
Hand rests 110 are provided on the left and right sides of the gantry base 101. The surface of the handrest 110 is located below the sample placement surface of the sample stage 106, protrudes from the gantry base 101 in the left-right direction when viewed from the observer, and is further inclined downward. The observer places his hand on the handrest and observes and manipulates the sample.
[0005]
[Problems to be solved by the invention]
However, the conventional device of this type has a problem in that the handrest projects in the left-right direction and the operability is poor. FIG. 5 shows the position of the hand on the hand rest during sample manipulation. The observer 111 faces the microscope, extends his arm at an angle of approximately 45 degrees from the elbow, and places his hand on the handrest 110. Since the handrest extends in the left-right direction and is inclined downward, the position where the hand is placed is more stable near the side of the sample. However, in this case, the wrist is greatly bent as shown in FIG. 5, and the delicate movement of the fingertip is hindered, and fatigue is a problem in long-time work. Further, since the hand rest covers the knob 109 for operating the reflection mirror, there is a problem that the knob is difficult to see and the operability of the knob is poor.
[0006]
The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a microscope mount capable of operating a sample in a more natural manner.
[0007]
[Means for Solving the Problems]
The present invention of claim 1 is as follows.
[0008]
A microscope pedestal having a gantry base having a sample placement surface and a handrest detachably provided on the gantry base so as to surround a portion on which the sample is placed, wherein the handrest is the sample The handrest has an overhanging portion that is inclined downward from the placement surface and overhangs obliquely in the left-right direction when viewed from the observer, the surface shape of the handrest is a curved surface, and the left and right overhanging portions The space for the microscope is a microscope pedestal characterized in that it is recessed closer to the optical axis side of the microscope than the protruding portion.
[0009]
According to a second aspect of the present invention, in the microscope mount according to the first aspect, the curved surface is a conical surface having a vertex on the optical axis of the microscope.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
One embodiment of a microscope mount in the present invention is shown in FIG. A column 2 is fixed to the gantry base 1. The microscope 4 is attached to a mount portion 3 that moves up and down along the column 2. A deflection mirror (not shown) that deflects illumination light from the lamp house 8 is provided inside the gantry base 1, and a knob 5 that rotates the deflection mirror is provided on a side surface of the gantry base 1. The handrest 6 is attached to the gantry base 1 and has a U-shape that surrounds the front side (observer side) of the portion (sample stage) 9 on which the sample is placed.
[0011]
The handrest 6 has an overhanging portion (6a, 6b) that protrudes obliquely in the left-right direction when viewed from the observer. The projecting portions 6a and 6b project in the direction of approximately 45 degrees on the left and right with respect to the direction from the microscope optical axis 4a toward the observer. Furthermore, a recess 6c that is recessed in the direction of the microscope optical axis 4a is formed at the center between the left and right projecting portions 6a and 6b.
[0012]
FIG. 2 is a diagram showing an AA cross section passing through the microscope optical axis 4a in FIG. As shown in FIG. 2, the surface 6 d of the handrest 6 is an inclined surface having an angle of θ degrees downward with respect to the sample placement surface of the sample stage 9. Note that θ is preferably around 10 degrees. Further, the surface 6d of the handrest other than that shown in FIG. 2 also has substantially the same angle as the AA cross section (FIG. 2) in any cross section passing through the microscope optical axis 4a. That is, the surface 6d of the handrest is formed to be a conical surface having a vertex on the microscope optical axis 4a.
[0013]
The handrest 6 is fixed to the gantry base 1 with a plurality of screws 7. The handrest 6 can be detached from the gantry base 1 by detaching the screw.
The handrest 6 is made of transparent polypropylene and is formed by injection molding. Polypropylene is characterized by excellent chemical resistance, low cost, easy molding, and high transparency. In addition, polyethylene and acrylic are also highly transparent materials and are suitable for the material of the handrest 6.
[0014]
FIG. 3 is a diagram showing a state in which a sample is operated with a hand placed on the handrest 6. The observer 10 can bend the elbows lightly and place his hands on the handrest 6 so that the left and right elbows form an angle of approximately 90 degrees. Therefore, the sample can be manipulated with almost no bending of the wrist. Even if the angle of the left and right elbows changes, the handrest surface 6d is a conical surface having a vertex on the microscope optical axis 4a, so that the hand can be placed stably toward the sample. There is no need to bend.
[0015]
Moreover, since the recessed part 6c is provided in the center part between overhang | projection parts 6a and 6b, even if an observer approaches a microscope and manipulates a sample, the handrest 6 contacts the observer's 10 body. There is no, it does not get in the way.
The handrest 6 of the present embodiment is provided so as to extend radially toward the observer side with the microscope optical axis as the center, so that it is easy to operate regardless of the direction in which the observer operates the sample. Moreover, since it inclines below the sample mounting surface, the hand can be placed on the handrest 6 in a more natural form. Furthermore, since the right-hand handrest portion and the left-hand handrest portion are integrally formed, only one component is required.
[0016]
The present invention is not limited to the above-described embodiment. For example, it may be divided into right-hand and left-hand handrests. In addition to the plurality of screws 7, the handrest 6 may be attached to the gantry base 1 by, for example, a fitting type.
[0017]
【The invention's effect】
According to the first aspect of the present invention, since the sample can be manipulated by placing the hand on the handrest in a natural manner, delicate manipulation of the fingertips is easy, and there is little fatigue even when working for a long time. .
