It is provided at the left end of the housing recess 16 in the left-right direction. Here, in general, electronic components are not mounted on the edge of the surface of the plate-shaped sample M. As shown in FIG. In the configuration of this embodiment, the outer portion of the plate-shaped sample M is held by the elastic portions 17 of the first plate-shaped sample mounting jig 14a and the second plate-shaped sample mounting jig 14b. Therefore, an electronic component (not shown) mounted on the surface of the plate-like sample M is less likely to come into contact with the inner surface of the sample-accommodating recess 16 .

Next, a procedure for placing the plate-shaped sample M on the plate-shaped sample placement jig set 14 attached to the shelf board 11 will be described below. First, the first plate-shaped sample mounting jig 14a and the second plate-shaped sample mounting jig 14b are arranged to face each other along the left-right direction.

In the first plate-shaped sample mounting jig 50a and the second plate-shaped sample mounting jig 50b according to the first modified example, for example, the plate-shaped sample M′ having a long side is accommodated in the sample accommodating concave portion 51. In this case, as shown in FIG. 4(a), the angle between the front surface portion 51a and the rear surface portion 51b is made smaller with the hinge 52 as the center. Then, the attachment grooves 15 are attached to the adjacent linear portions 11a. As a result, the vertical depth of the sample housing recess 51 increases. As a result, the plate-shaped sample M' can be accommodated in the deep sample-accommodating concave portion 51, so that the stability of the plate-shaped sample M' is improved. On the other hand, when a plate-shaped sample M'' having a large thickness and having a large-sized component m mounted on its surface is accommodated in the sample accommodation recess 51, as shown in FIG. and the rear surface portion 51b. Then, every other mounting groove portion 15 is mounted on the linear portion 11a. As a result, the pitch in the front-rear direction of the sample housing recesses 51 increases. As a result, the distance between the plate-shaped sample M'' and the front surface portion 51a can be increased, and the large-sized component m mounted on the surface of the plate-shaped sample M'' and the inner surface of the sample housing recess 51 (the front surface portion) can be separated from each other. 51a) can be avoided.

However, in this modified example, as shown in FIG. 5, each of the first plate-shaped sample mounting jig 60a and the second plate-shaped sample mounting jig 60b is composed of one plate-shaped member. The plate-shaped first plate-shaped sample mounting jig 60a and the second plate-shaped sample mounting jig 60b are each provided with five downwardly opening mounting grooves 65 and upwardly opening slits ( A sample accommodating recess 66 of the present invention is formed.

The mounting groove portion 65 can accommodate the linear portion 11a when approaching the shelf plate 11 from above downward. The shape of the mounting groove portion 65 is, as in the above-described embodiment, an arc shape when viewed from the left and right direction, and the inner diameter thereof is substantially the same as the diameter of the linear portion 11a. The slit 66 is a portion where the plate-shaped sample M is placed. The width of the slit 66 in the front-rear direction is substantially the same as the thickness of the plate-like sample M, and the plate-like sample M is held so as to be sandwiched between the slits 66 . Further, the slit 66 is positioned above the mounting groove 65 when the first plate-shaped sample mounting jig 60a and the second plate-shaped sample mounting jig 60b are mounted on the shelf board 11. . Further, an extending portion 67 extending downward from the end portion of the mounting groove portion 65 is formed between two adjacent mounting groove portions 65 . The extension portion 67 prevents the mounting groove portion 65 from coming off the linear portion 11a. Further, the weight of the extension portion 67 improves the stability of the first plate-shaped sample mounting jig 60a and the second plate-shaped sample mounting jig 60b attached to the shelf board 11 .
