- a wiping position U3 is provided at the position, and a standby position U4 is provided at a position opposite to the measurement position U2 by 180 °.
- the sample plate 11 is driven to rotate intermittently by 90 ° angles so that the four sample holders 12 stop at the four positions U1 to U4 for a predetermined time. It is. Therefore, if attention is paid to a certain sample holding part 12, the sample holding part 12 moves along with the intermittent rotation of the sample plate 11, the sample supply position Ul ⁇ the measurement position U2 ⁇ the wiping position U3 ⁇ the standby position U4. , And then return to the sample supply position U1, and this is repeated cyclically. At some point, one of the four sample holders 12 is at the sample supply position U1, one at the measurement position U2, one at the wiping position U3, and the other at standby. At position U4.

- the transmitted light that has passed through the liquid sample filled in the space passes through the slit 19 through just below. Therefore, the depth of the groove of the sample holder 12 becomes the optical path length of the liquid sample, and the optical path length is uniquely determined without depending on the amount of the liquid sample dropped first. Since specific wavelength components in the measurement light are absorbed in the liquid sample, the light intensity signal for each wavelength simultaneously detected by the detector 21 is processed by a signal processing unit (not shown) to transmit the liquid sample. A spectrum reflecting the characteristics can be created.
- the portion other than the portion where the liquid sample exists is covered by the light shielding member ib, even if the light diameter of the measurement light irradiated on the upper surface of the sample plate 11 is larger than the width of the groove of the sample holder 12, The protruding part is shielded by the light shielding member l ib

- a circular hole penetrating therethrough is provided, and a cylindrical body id having a transparent material force is provided in the hole.
- the flat lower surface of the cylindrical body l id is flush with the lower surface of the base 11c, and the flat upper surface of the cylindrical body l id protrudes above the upper surface of the base 11c.
- FIG. 7 (b) the force by which a small amount of liquid sample is dropped on the upper surface of the cylindrical body id, and the dropped liquid sample becomes spherical due to surface tension.
- the window plate 22 is lowered to a position where the distance between the lower surface thereof and the upper surface of the cylindrical body id is a predetermined distance.
- the liquid sample pushed by the window plate 22 has a force that causes the spherical droplets to collapse and spread in a narrow space between the lower surface of the window plate 22 and the upper surface of the cylindrical body id. Is filled with liquid sample. Therefore, even in this way, the optical path length of the measurement light in the liquid sample is determined, and the transmission measurement similar to the above can be performed by measuring the transmitted light passing through the cylindrical body id and passing downward.
- the structure in which the sample holding portion 12 protrudes upward has an advantage that the liquid sample can be easily wiped off by the cleaning pad as compared with the case where the sample holding portion 12 has a groove shape as described above.

- both a so-called dry wiping means having absorptivity (water absorption) and a so-called wet wiping means containing a predetermined solvent are used together. Also good. Further, as apparent from the above description, since no operation is performed on the sample holding unit 12 at the standby position U4, the wiping operation may be performed at this position U4.
- the cleaning pads 26 and 27 become dirty, contamination may be caused.
- an automatic feeding mechanism for absorbent material such as nonwoven fabric is provided, and the absorbent material once used to absorb the liquid sample is reused. I ’m not doing it, but it ’s not.
- the number of sample holders 12 and the arrangement on the sample plate 11 are one. It is also an example and it is clear that it can be changed as appropriate. Furthermore, the sample plate 11 may be driven to reciprocate linearly or arcuately, for example, instead of rotating the sample plate 11 as described above.
