Recently, a technology has been put into practical use that combines a reflection colorimeter and a computer to measure the color of slivers such as wool tops. This colorimetry is performed by applying the colorimetric surface of a sample such as a sliver to the colorimetric window of a colorimeter and measuring the reflected light. In this way, since colorimetry is performed by measuring reflected light, it is most important to make the colorimetric surface of the sample uniform in order to improve the accuracy of colorimetry. When the condition is non-uniform, for example, when light is undulating or when light enters inside due to gaps, etc., the accuracy (reproducibility) of color measurement decreases. However, since it is necessary to set the sample's colorimetric surface uniformly against the colorimetric window of the colorimeter in this way, individual differences may occur, making it difficult to perform accurate colorimetry. I couldn't. This idea was made in view of these circumstances, and includes a base having an inwardly flanged opening corresponding to the colorimetric window of the colorimeter and a hole extending from this opening, and a hole in the base. The hole in the base is provided with a push rod that pushes part or all of the sample into the opening and exposes it from the opening under tension, and a holder that holds the push rod in the pushed state. It is formed in a shape that spreads out from the middle in the opposite direction, and can be detachably attached to the colorimeter with the opening of the base aligned with the colorimeter window of the colorimeter. The gist of this is the sample stage. In other words, with this sample stand for colorimeter, all you have to do is push part or all of the sample, such as a sliver, into the hole in the base using the push rod, and tension will be applied to the colorimetric surface to automatically detect the sample. Since it is in a uniform state, it does not take time to set the sample during color measurement as in the conventional method, and it can be done easily. Therefore, it becomes possible to perform highly accurate color measurement without individual differences. Next, this invention will be explained in detail based on examples. FIG. 1 is an external perspective view of an embodiment of this invention, FIG. 2 is a sectional view taken along line A-A' of the base, and FIG. 3 is a perspective view of the base turned over. In these figures, reference numeral 1 denotes a base, which is composed of a substrate 2, a cylindrical body 3, a side plate 4, and a reinforcing plate 5. An opening 6 is formed in the center of the substrate 2. The cylinder 3 is provided concentrically with the opening 6 of the substrate 2, and its inner wall surface 7
It spreads out from the middle part upwards in a rasp-like shape. A pair of left and right side plates 4 are provided integrally with the substrate 2, and a magnet plate 8 is attached and fixed to the outer surface of each side plate by an attachment part 9. As shown in FIG. 3, the back surface of the substrate 2 (this surface faces the colorimetric window side of the colorimeter (not shown)) has an opening with a slightly smaller diameter than the opening 6 of the substrate 2 (see FIG. 2). 1
A metal plate 11 having the same shape as the substrate 2 is attached with the center of its opening 10 aligned with the center of the opening 6 of the substrate 2. The opening edge of this metal plate 11 forms an inward flange 10a of the opening 6 of the substrate 2, as shown in FIG. Reference numeral 12 denotes a push rod for pushing a sample (not shown) into the cylindrical body 3, and its tip pressing surface portion 13 is made of a white synthetic resin plate in consideration of spectral reflectance. This push rod 12
is set to have a diameter larger than the opening 10 of the metal plate 11 and smaller than the opening 6 of the substrate 2, so that its tip reaches the bottom of the cylindrical body 3 when pressed. 14 is an iron push plate provided at the rear end of the push rod 12;
When the push rod 12 is pushed in, it is attracted to the magnet plate 8 of the side plate 4 and the push rod 12 is kept in the pushed state. The sample is attached to the sample stand for the colorimeter in the following manner. That is, as shown in FIG. 4, the sliver 15 is placed on the reinforcing plate 5 with the longitudinal direction of the sliver 15 aligned with the longitudinal direction of the side plate 4. Then, from that state, push rod 1
2 in the direction of the arrow, the sliver 15 is pressed by the tip pressing surface 13 of the push rod 12, passes through the flap-shaped part at the top of the cylinder 3, reaches the opening 6 of the substrate 2, and is exposed to the outside from there. do. During this pushing, the part of the sliver 15 located on the outer circumferential surface of the pusher rod 12 is strongly pinched between the outer circumferential surface of the pusher rod 12 and the inner circumferential surface of the cylinder 3, making it impossible to keep up with the pushing progress of the pusher rod 12. . However, since the push rod 12 is pushed further, tension is applied to the portion of the sliver 15 located on the tip pressing surface 13 of the push rod 12 (which is exposed from the substrate opening 6 and becomes the colorimetric surface). , waviness etc. on the colorimetric surface are eliminated and the colorimetric surface becomes uniform. This state is maintained by the attraction of the push plate 14 to the magnet plate 8. Note that the flange portion 10a formed by the opening edge of the metal plate 11 is connected to the tip pressing surface portion 13 of the push rod 12.
This acts to prevent the portion of the sliver 15 pressed by the opening 10 from coming off. The sample stage for the colorimeter, on which a uniform colorimetric surface has been formed in this way, is attached to the colorimeter in the following manner and is used for colorimetry. That is, as shown in FIG. 6, the handle 17 of the colorimeter 16 is pulled toward the user, and the push plate 21 is moved back against the spring 18 as shown in FIG. 7, thereby exposing the colorimeter window 19. Next, the sample stand 20 on which the sliver 15 is attached is placed so that its metal plate side faces the side part of the colorimetric window of the colorimeter 16, and the base opening 6 and the colorimeter window 19 are aligned, and from that state the eighth As shown in the figure, this is carried out by returning the handle 17 to its original state and pressing the push plate 14 of the sample stage 20 with the push plate 21. Note that the sliver is omitted in FIG. 8 for convenience of illustration. In this embodiment, the pushed state is maintained by attracting the pushing plate 14 of the pushing rod 12 to the magnet plate 8, but this is not restrictive. For example, a hook may be used. Next, using the sample stand for the colorimeter of the above example,
The results of color measurement of the dyed wool sliver are shown in the following table in comparison with the case without using a sample stage. The sample color is sky blue (L ^* = 53.1, a ^* = -
4.2, b ^* = −29.8).

になる。[Table] From the table above, it can be seen that when color measurement is performed using a sample stage, the variation in color measurement is significantly reduced and the accuracy of color measurement is significantly improved. Since the colorimeter sample stand of this invention is constructed as described above, the condition of the colorimetric surface can be made uniform and highly accurate colorimetry can be achieved. Furthermore, since a uniform colorimetric surface can be easily formed without individual differences, the conventional problems of time-consuming colorimetric work and individual differences in accuracy do not occur. Furthermore, since this sample stage does not damage the sample, it becomes possible to repeatedly measure the same sample, and it also becomes possible to cope with variations in the amount of sliver.
