Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sample holder for a colorimeter suitable for colorimetry of thread-like samples.

Prior Art A colorimeter having a sample fixing means as shown in FIG. 3 and the lower surface of a mounting frame 5 constituting a measurement window 4 provided below.

Problem: The sample placed on the sample stage must be fixed and maintained in its position until the end of the measurement. However, when the sample consists of a large number of thread-like objects, the above-mentioned fixing method does not allow the sample to be fixed and moves freely while the sample stage 2 is being raised, making it impossible to measure the thread-like objects in a desired state.

The present invention is a sample holder that is especially suitable when the sample consists of a large number of filamentous materials.By flattening the filamentous sample in advance and firmly holding it on the sample stage, color measurement becomes more accurate. The present invention provides a sample stage that allows color measurement results to be obtained with good reproducibility.

Solution The sample holder of the present invention consists of an upwardly convex sample stand body, which has a flat part on which the sample is placed, and a stand with a falling surface connected to the flat part on the base, and a falling surface on the side of the main body. A total of four elastic body locking devices, an elastic body, and two rollers are provided at a point below the perpendicular line drawn from and on the opposite side of the main body center line with respect to the falling surface This is a sample holder for a colorimeter, characterized in that a roller is pressed into contact with the sample stage main body by an elastic body latched to the sample stage main body.

In the sample holder of the present invention, the roller is pressed against the flat part of the sample stage body by an elastic body, and the filamentous sample is placed between the flat part of the sample stage body and the roller. Slide the roller over the sample, flattening the sample surface, lower it to the falling surface of the stage, and stop. In this way, the filamentous sample can be fixed on the sample stage in a state that it is tightly aligned with the flat part. Therefore, the sample does not move even when the sample stage is subsequently raised and placed between it and the lower surface of the mounting frame.

In order to fix the roller with the elastic body at the lowest point of the falling surface of the platform (the surface in contact with the top surface of the base), the roller must slide upward from the falling surface in the direction in which the elastic body is pulled. Good. Therefore, even if the falling surface 9 is not perpendicular to the flat surface 11 as shown in FIG. 4, it is necessary to pull it below the perpendicular line 14 from the falling surface. In addition, since it is necessary to firmly hold the sample at the location where the roller is fixed on the falling surface, it is better to have a stronger tensile strength when the roller is on the falling surface than when it is on the flat part. That is, the elastic locking tool 13 provided on the side surface of the sample stage main body is located below the perpendicular line 14 from the falling surface drawn from the contact point between the falling surface and the base, and with respect to the falling surface. It may be provided on the opposite side of the center line 15 of the sample stage body.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In FIG. 2, reference numeral 6 denotes a sample stage main body having a convex cross-sectional shape in the longitudinal direction, and a mounting stage 12 having a flat part 11 on which the sample is placed and falling surfaces 9, 9' connected to the flat part. and the base 10 are integrated.
The side surface of the sample stage main body is provided with an elastic member latching member 13 for securing the rubber strings 8, 8'.

7 and 7' are hollow rollers that are slightly longer than the width of the sample stage body and placed on the sample stage body in a direction perpendicular to its longitudinal direction (width direction). Also 8,
8' moves the two rollers 7, 7' placed on the sample stand main body onto the upper surface of the sample stand main body, that is, the flat part 1.
1 and the falling surface 9. As shown in FIG. , and the ends of each rubber string are fixed to an elastic body locking tool 13 provided on the side surface of the sample stage main body.

When no sample is attached, the two rollers 7,
7' are pulled inwardly by the action of the rubber strings 8, 8', so that they are located adjacent to each other on the central flat part of the sample stage body.

When attaching a sample, lift the rollers 7, 7, and place the rollers between the flat part of the sample stage main body and the rollers.
Thread-like samples are lined up in the longitudinal direction of the sample stage body and inserted between them. If necessary, a roller locking piece (not shown) is provided on the side of the sample stage body to lift the rollers, and the rollers 7, 7' are held in the lifted state, and the rollers are held between the flat part and the rollers. A gap may be created and the filamentous samples may be lined up.

After the sample is sandwiched, the rollers 7, 7' are lowered, and the rollers 7, 7' are slid over the sample to make the surface of the sample flat while moving outward from each other against the tensile force of the rubber strings 8, 8'. Thereafter, the sample is set on the sample stand main body by locking the rollers 7, 7' to the falling surfaces 9, 9' of the sample stand main body 6 (third stage).
figure). Note that if the sample stage main body is not white, it is necessary to attach a white plate to the flat surface of the sample stage main body.
