本考案は、液体試料の内容物を均一に拡散させ
るための、とくに自動分析装置用の自動試料供給
装置とともに用いる攪拌装置に関するものであ
る。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stirring device for uniformly dispersing the contents of a liquid sample, particularly for use with an automatic sample supply device for an automatic analyzer.
自動分析装置に供給される試料は測定時間と同
期して、所定の工程中に順次に攪拌されて行くこ
とが必要とされる。
The sample supplied to the automatic analyzer is required to be stirred sequentially during predetermined steps in synchronization with the measurement time.
これを行う従来の装置としては、細長い攪拌具

螺旋状の攪拌具を偏心回転させる特開昭54−
134690号公報に記載のものなどがある。 Conventional devices for this purpose include a device developed in Japanese Patent Application Laid-open No. 52 (1972), in which a long and thin stirring device is inserted into the sample to cause precession.
-The one described in Japanese Patent Publication No. 28390, the one in Japanese Patent Application Laid-open No. 130988, which rotates the stirrer eccentrically,
JP-A 1983-1999 - Eccentric rotation of a spiral stirrer
Some examples include those described in Publication No. 134690.
また偏心回転体に容器を圧接して、中の試料を
共振させる技術が実開昭59−142752号公報に開示
されている。 Furthermore, Japanese Utility Model Application Publication No. 142752/1983 discloses a technique in which a container is brought into pressure contact with an eccentric rotating body to cause a sample inside to resonate.
また展望用の観覧車状の試料架台を回転させる

う、米国特許4475411号公報に記載のものなどが
ある。 There is also a method described in US Pat. No. 4,475,411, in which a sample holder shaped like a Ferris wheel for observation is rotated to perform sample supply and overturning stirring at the same time.
試料内に攪拌具を挿入して攪拌を行うものは、

があつた。
For those that stir by inserting a stirring tool into the sample,
When setting a large number of sample containers in the sample supply device, all of the container caps must be opened in advance and left for a long period of time until all measurements are completed. This alters the quality of the sample to such an extent that reproducibility cannot be achieved. In addition, there were other problems such as the high probability of contamination with samples containing pathogens, which was undesirable.
一方、容器を偏心回転体に圧接する方法は、試
料が極少量である場合に限り有効であるが、試料
量が多くなると攪拌に時間がかかり過ぎて測定タ
イミングと同期しない、あるいは攪拌が不充分に
なるという問題があつた。 On the other hand, the method of press-contacting a container to an eccentric rotating body is effective only when the amount of sample is extremely small; however, when the amount of sample is large, stirring takes too much time and may not be synchronized with the measurement timing, or stirring may be insufficient. There was a problem with becoming.

つて攪拌効果が影響される点、逆に配列が攪拌条
件に規制される点などの不便があるという問題が
あつた。 In addition, in the US patent, the setting position of the sample and the stirring effect are inseparable, and there are inconveniences such as the stirring effect being affected by the order in which the sample containers are arranged, and conversely, the arrangement being regulated by the stirring conditions. There was a problem.
本考案はこれらの問題点に鑑みなされたもので
試料容器の栓をしたままで、比較的多量の試料量
に対しても迅速な攪拌を行うことができ、しかも
供給装置と独立に攪拌条件を選択できる試験管転

み、ハンド部１は試験管の保持を解放することに
なる。 The bases of the tilt table 49 and the abutment table 50 are screwed to the front part of the base plate 10 so that their positions can be adjusted. Therefore, the hand portion 1 is lowered and the roller bearings 42 and 43 are moved to the inclined table 49.
Only when the lower end of the abutment rod 54 abuts the abutment stand 50 will the hand portion 1 release its hold on the test tube.
第２図はハンド部１が上位置にあり、試験管５
２を保持している状態を示す。 In Figure 2, the hand section 1 is in the upper position and the test tube 5 is
2 is held.
次に回転駆動部４は駆動軸２３から下した垂線

れ、試験管架台５３に保持される。 When the stirring is finished, the vertical drive section 2 drives the hand section 1 downward. When the hand portion 1 is in the downward position as shown in FIGS. 3 and 5, the roller bearings 42 and 43 hit the inclined table 49 and are pushed apart laterally along the guide pins 36 and 37 as shown in FIG. , the hit rod 54 hits the hit stand 50 and the handle 27 is pushed up. The test tube is released from the hand section 1 and held on the test tube holder 53.
