装置に関する。[Detailed explanation of the invention] (Industrial application field) This invention is a drive device for the sample collection part in a sample analyzer, specifically, a drive device for the sample collection section in a sample analyzer, and more specifically, a drive device for feeding a sample arbitrarily specified from a plurality of installed samples into the analyzer. The present invention relates to a drive device for a sample collection section in a so-called automatic sample analyzer (auto sampler) that chemically analyzes samples.

をおこなう。(Prior Art) As a conventional automatic sample analyzer, for example, the following apparatus is known as an automatic liquid sample analyzer. That is, several cc of liquid sample, e.g. blood, urine, etc.
A plurality of recesses are formed in each of the x and y planes on the plate and stored in the recesses. Then, a bar that can be moved to a desired position in the y-axis direction is stretched over the top surface of the sample in the x-axis direction, and a dropper that can be positioned at a desired position on the bar, that is, movable in the x-axis direction of the plate, is attached to the bar. Fixed in a slidable manner. When collecting any sample, the x-axis, y-axis on the sample plate
Obtain the axis coordinates, move the bar and the dropper according to the coordinates, and place the dropper on any sample. Next, the dropper is lowered to aspirate the sample, and the sample is sent to an analyzer for chemical analysis.
更に、特開昭57−90162「試料配分器」が知られ
ている。 Further, JP-A-57-90162 "Sample Distributor" is known.

結することが生じ、そのため駆動部分の作動を悪
化する課題を有した。(Problem to be solved by the invention) In the conventional sample analyzer, the drive device for the sample collection section moves in the y-axis direction by
Since movement in the x-axis direction was accomplished by moving a dropper that was slid and fixed to the bar using a bar that spanned in the axial direction, the driving section was exposed on the top surface of the sample. In particular, when the motor that drives the dropper is fixed to the bar, the motor itself is exposed above the sample. However, some samples are highly volatile, and such volatile components may form condensation on the drive section, which poses a problem of deteriorating the operation of the drive section.
又、仮にこの様な従来例で露結を防ぐために、
シールを施しても、試料上面上に駆動部がくる課
題を本質的に有しているため、シールは完全とは
ならない課題を有した。更に、同一のｘ軸方向へ
の移動機構のまま駆動部のみを試料上面から除く
ことは、駆動部が更に複雑化する課題を有した。 Also, in order to prevent dew condensation in such a conventional example,
Even if a seal was applied, there was a problem that the seal was not perfect because the drive unit was essentially placed above the top surface of the sample. Furthermore, removing only the drive section from the top surface of the sample while keeping the same mechanism for moving in the x-axis direction has the problem that the drive section becomes even more complex.
他方、特開昭57−90162記載の「試料配分器」
では、腕だけではｘ，ｙ，ｚの３軸方向には移動

した。 On the other hand, the "sample distributor" described in JP-A-57-90162
In this case, the arm alone cannot move in the three axes (x, y, and z); the pedestal on which the container is placed must be moved in the x-axis direction separately from the movement of the arm, and the movement of the container depends on the contents. This poses an undesirable problem as it may cause spillage, etc.
