Description

本発明は、自動分析装置に関する。 The present invention relates to an automatic analyzer.

従来、各種の試薬と試料（検体）を混合させて分析を行う自動分析装置は、これら各種の試薬を保持する試薬保冷庫を備え、この試薬保冷庫内は、一般に室温より低めの温度に保たれている。また、試薬保冷庫は、保持する試薬を容易に吸引できるように、蓋部材の一部に試薬吸引用の孔を有しているため、この孔から外気が流入することで、試薬保冷庫内に結露が発生する場合がある。この結露が試薬保冷庫内に滞留し続けると、やがてカビが発生し、試薬保冷庫環境が悪化してしまう。 Conventionally, an automatic analyzer that mixes various reagents and a sample (sample) for analysis is provided with a reagent cold storage that holds these various reagents, and the inside of this reagent cold storage is generally kept at a temperature lower than room temperature. It is leaning. Further, since the reagent cold storage has a hole for suction of the reagent in a part of the lid member so that the reagent to be held can be easily sucked, the inside of the reagent cold storage is caused by the inflow of outside air from this hole. Condensation may occur on the surface. If this dew condensation continues to stay in the reagent cold storage, mold will eventually develop and the reagent cold storage environment will deteriorate.

そこで、特許文献１には、結露を試薬保冷庫外へ排出する技術として、「分析対象となる検体と混合する試薬を保冷する試薬保冷庫と、前記試薬保冷庫内に格納され、回転駆動する試薬ディスクと、前記試薬ディスクの外側の側面に取り付けられ、前記試薬保冷庫の内壁と接触する弾性部材と、を備える」（特許文献１の請求項１）自動分析装置が開示されている。また、この特許文献１には、「試薬ディスクの外側の側面のみならず、試薬ディスクの底面にも、この弾性部材を取り付けた」（特許文献の段落００１４）構成についても開示されている。 Therefore, in Patent Document 1, as a technique for discharging dew condensation to the outside of the reagent cold storage, "a reagent cold storage that keeps the reagent to be mixed with the sample to be analyzed cold, and a reagent cold storage that is stored in the reagent cold storage and driven to rotate". A reagent disk and an elastic member attached to the outer side surface of the reagent disk and in contact with the inner wall of the reagent cold storage are provided ”(Patent Document 1 claim 1). Further, Patent Document 1 also discloses a configuration in which "this elastic member is attached not only to the outer side surface of the reagent disc but also to the bottom surface of the reagent disc" (paragraph 0014 of the patent document).

しかし、特許文献１に記載の技術では、試薬ディスクの径方向に延在させた弾性部材でかき集めた結露水を、結露水に加わる遠心力と、径方向外側へ向けて下る試薬保冷庫の底壁の傾斜と、によって、試薬保冷庫の底壁の最外周に形成された排水口へ誘導している。 However, in the technique described in Patent Document 1, the centrifugal force applied to the condensed water collected by the elastic member extending in the radial direction of the reagent disk and the bottom of the reagent cold storage that descends outward in the radial direction. The slope of the wall guides it to the drainage port formed on the outermost circumference of the bottom wall of the reagent cold storage.

本発明の目的は、結露水を排出する排水口の位置や、試薬保冷庫の底壁の形状によらず、試薬保冷庫内に発生した結露水を排出することのできる自動分析装置を提供することである。 An object of the present invention is to provide an automatic analyzer capable of discharging the condensed water generated in the reagent cold storage regardless of the position of the drain port for discharging the condensed water and the shape of the bottom wall of the reagent cold storage. That is.

上記課題を解決するため、本発明は、試薬と検体を混合させて分析を行う自動分析装置であって、底壁に排水口を有する試薬保冷庫と、前記試薬保冷庫の内部に配置され、試薬容器を設置する試薬ディスクと、を備え、前記試薬ディスクの下面側には、前記試薬保冷庫の底壁上面と接しながら前記試薬ディスクと共に回転する摺接体が設けられており、前記摺接体の摺接部が、前記試薬ディスクの径方向に対して所定の傾斜角を成していることを特徴とする。 In order to solve the above problems, the present invention is an automatic analyzer that mixes a reagent and a sample for analysis, and is arranged inside a reagent cold storage having a drain port on the bottom wall and the reagent cold storage. A reagent disk on which a reagent container is installed is provided, and a sliding contact body that rotates together with the reagent disk while being in contact with the upper surface of the bottom wall of the reagent cold storage is provided on the lower surface side of the reagent disk. The sliding contact portion of the body is characterized in that it forms a predetermined inclination angle with respect to the radial direction of the reagent disk.

本発明によれば、結露水を排出する排水口の位置や、試薬保冷庫の底壁の形状によらず、試薬保冷庫内に発生した結露水を排出することのできる自動分析装置を提供することが可能となる。 According to the present invention, there is provided an automatic analyzer capable of discharging the condensed water generated in the reagent cold storage regardless of the position of the drain port for discharging the condensed water and the shape of the bottom wall of the reagent cold storage.

以下、本発明の実施の形態を図面に基づいて詳細に説明する。なお、実施の形態を説明するための全図において、同一部には原則として同一の符号を付し、その繰り返しの説明は省略する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in all the drawings for explaining the embodiment, in principle, the same reference numerals are given to the same parts, and the repeated description thereof will be omitted.

図１は、実施例１に係る自動分析装置１０１の概略を示す平面図である。自動分析装置１０１は、試薬と試料（検体）を混合し、混合した測定試料の分析を自動で行う。図１に示されるように、自動分析装置１０１は、搬送ライン１と、試料を吸引する試料プローブ２と、反応容器供給庫３と、反応容器供給機構４と、反応容器テーブル５と、反応測定装置６と、試薬撹拌棒７と、試薬ディスク８と、試薬プローブ１０２と、試薬保冷庫１０３と、を有する。 FIG. 1 is a plan view showing an outline of the automatic analyzer 101 according to the first embodiment. The automatic analyzer 101 mixes the reagent and the sample (sample), and automatically analyzes the mixed measurement sample. As shown in FIG. 1, the automatic analyzer 101 includes a transfer line 1, a sample probe 2 for sucking a sample, a reaction vessel supply chamber 3, a reaction vessel supply mechanism 4, a reaction vessel table 5, and reaction measurement. It has an apparatus 6, a reagent stirring rod 7, a reagent disk 8, a reagent probe 102, and a reagent cold storage 103.

反応容器供給庫３は、複数の反応容器９を保持する。反応容器供給機構４は、反応容器供給庫３が保持する反応容器９を反応容器テーブル５へ供給する。反応容器テーブル５は、供給された反応容器９を、自らを回転させることで試料プローブ２から試料が吐出される試料吐出位置まで移動させる。 The reaction vessel supply chamber 3 holds a plurality of reaction vessels 9. The reaction vessel supply mechanism 4 supplies the reaction vessel 9 held by the reaction vessel supply chamber 3 to the reaction vessel table 5. The reaction vessel table 5 moves the supplied reaction vessel 9 to the sample discharge position where the sample is discharged from the sample probe 2 by rotating itself.

試薬保冷庫１０３は、試薬が入った試薬容器１０７を収容する。ここで、図２〜図４を用いて試薬保冷庫１０３の概略構成について説明する。図２は、試薬保冷庫を上方から見た平面図であり、図３は、試薬保冷庫を正面から見た正面図であり、図４は、試薬保冷庫の内部にある試薬ディスクを上方から見た平面図である。 The reagent cold storage 103 houses the reagent container 107 containing the reagent. Here, the schematic configuration of the reagent cold storage 103 will be described with reference to FIGS. 2 to 4. FIG. 2 is a plan view of the reagent cold storage from above, FIG. 3 is a front view of the reagent cold storage from the front, and FIG. 4 is a front view of the reagent disk inside the reagent cold storage from above. It is a plan view as seen.

図２，図３に示すように、試薬保冷庫１０３は、上端が開放された円筒状の形状となっており、その上方開口には、蓋部１０５を有している。なお、図１では、蓋部１０５の一部を削除して、試薬保冷庫１０３の内部を示した。図１，図２に示すように、試薬保冷庫１０３の蓋部１０５には、試薬を吸引するための吸引孔１０４が形成されている。また、図４に示すように、試薬保冷庫１０３の内部には、試薬ディスク８が配置されており、この試薬ディスク８上には、放射状に複数の試薬容器１０７が設置されている。 As shown in FIGS. 2 and 3, the reagent cold storage 103 has a cylindrical shape with an open upper end, and has a lid 105 at its upper opening. In FIG. 1, a part of the lid 105 was deleted to show the inside of the reagent cold storage 103. As shown in FIGS. 1 and 2, a suction hole 104 for sucking the reagent is formed in the lid 105 of the reagent cold storage 103. Further, as shown in FIG. 4, a reagent disc 8 is arranged inside the reagent cold storage 103, and a plurality of reagent containers 107 are radially installed on the reagent disc 8.

そして、本実施例の自動分析装置１０１では、まず、図１に示す試薬撹拌棒７が、試薬撹拌位置まで水平移動した後、下方へ移動して、吸引孔１０４を介して試薬容器１０７へ挿入される。さらに、試薬撹拌棒７は、試薬容器１０７に挿入された状態で回転することで、試薬容器１０７に入った試薬を撹拌する。試薬を撹拌した試薬撹拌棒７は、上方へ移動して試薬容器１０７から引き抜かれる。 Then, in the automatic analyzer 101 of the present embodiment, first, the reagent stirring rod 7 shown in FIG. 1 moves horizontally to the reagent stirring position, then moves downward, and is inserted into the reagent container 107 through the suction hole 104. Will be done. Further, the reagent stirring rod 7 rotates while being inserted into the reagent container 107 to agitate the reagent contained in the reagent container 107. The reagent stirring rod 7 in which the reagent is agitated moves upward and is withdrawn from the reagent container 107.

次に、試薬プローブ１０２が、試薬吸引位置まで水平移動した後、下方へ移動して、吸引孔１０４を介して試薬容器１０７へ挿入される。そして、試薬プローブ１０２は、試薬容器１０７に挿入された状態で、試薬容器１０７に入った試薬を吸引する。試薬を吸引した試薬プローブ１０２は、上方へ移動して試薬容器１０７から引き抜かれる。 Next, the reagent probe 102 moves horizontally to the reagent suction position, then moves downward, and is inserted into the reagent container 107 through the suction hole 104. Then, the reagent probe 102 sucks the reagent contained in the reagent container 107 while being inserted into the reagent container 107. The reagent probe 102 that has sucked the reagent moves upward and is withdrawn from the reagent container 107.

その後、試薬プローブ１０２は、試薬吐出位置まで水平移動した後、下方へ移動して、反応容器テーブル５上の反応容器９内に試薬を吐出する。試薬が吐出された後、反応容器テーブル５は、自らを回転させることで、反応容器９を試料吐出位置まで移動させる。 After that, the reagent probe 102 moves horizontally to the reagent discharge position and then moves downward to discharge the reagent into the reaction vessel 9 on the reaction vessel table 5. After the reagent is discharged, the reaction vessel table 5 rotates itself to move the reaction vessel 9 to the sample discharge position.

搬送ライン１は、試験管ラック１０に保持された試料容器１１を試料吸引位置まで搬送する。その後、試料プローブ２が、試料容器１１の上方開口から下降して試料容器１１内に挿入される。そして、試料プローブ２は、試料容器１１に挿入された状態で、試料容器１１に入った試料を吸引する。試料を吸引した試料プローブ２は、上昇して試料容器１１から引き抜かれる。 The transport line 1 transports the sample container 11 held in the test tube rack 10 to the sample suction position. After that, the sample probe 2 descends from the upper opening of the sample container 11 and is inserted into the sample container 11. Then, the sample probe 2 sucks the sample contained in the sample container 11 while being inserted into the sample container 11. The sample probe 2 that has sucked the sample rises and is pulled out from the sample container 11.

その後、試料プローブ２は、試料吐出位置まで水平移動した後、下方へ移動して、反応容器テーブル５上の反応容器９へ、吸引した試料を吐出する。そして、図示しない撹拌機構が、反応容器９に吐出された試薬と試料とを撹拌する。撹拌された試薬と試料は所定時間放置される。放置された後、反応容器９は、反応測定装置６まで移動される。そして、反応測定装置６は、移動された反応容器９に入った試薬と試料の反応状態を測定する。 After that, the sample probe 2 moves horizontally to the sample discharge position and then moves downward to discharge the sucked sample into the reaction vessel 9 on the reaction vessel table 5. Then, a stirring mechanism (not shown) stirs the reagent discharged into the reaction vessel 9 and the sample. The stirred reagent and sample are left for a predetermined time. After being left unattended, the reaction vessel 9 is moved to the reaction measuring device 6. Then, the reaction measuring device 6 measures the reaction state of the reagent and the sample in the moved reaction vessel 9.

なお、試薬容器１０７は、試薬ディスク８上に１個以上、例えば４個設置されており、試薬ディスク８が回転することによって、試薬撹拌棒７及び試薬プローブ１０２で攪拌／吸引する試薬を入れ替えることが可能となっている。 In addition, one or more, for example, four reagent containers 107 are installed on the reagent disk 8, and when the reagent disk 8 rotates, the reagents to be stirred / sucked by the reagent stirring rod 7 and the reagent probe 102 are replaced. Is possible.

図６は、図２に示した試薬保冷庫のＡ−Ａ断面を示す図であり、図７は、同Ａ−Ａ断面の斜視図である。本実施例では、試薬保冷庫の底壁のうち、外周端（側壁の内面に隣接する位置）と内周端（試薬ディスク８の回転軸に隣接する位置）との中間の位置に、排水口１１１が設けられている。また、本実施例の試薬保冷庫の底壁上面には、排水口１１１に向けて下る傾斜が径方向に設けられている。ここで、傾斜の角度が大き過ぎると試薬保冷庫内を均一に保冷することが難しくなるため、１０度以下の角度とするのが望ましい。なお、この傾斜がなくても後述の摺接体により底壁の結露水を排水することは可能であるが、この傾斜があることで排水効率が高まる。 FIG. 6 is a view showing a cross section of AA of the reagent cool box shown in FIG. 2, and FIG. 7 is a perspective view of the cross section of AA. In this embodiment, the drainage port is located at an intermediate position between the outer peripheral end (position adjacent to the inner surface of the side wall) and the inner peripheral end (position adjacent to the rotation axis of the reagent disk 8) of the bottom wall of the reagent cold storage. 111 is provided. Further, on the upper surface of the bottom wall of the reagent cool box of this embodiment, an inclination descending toward the drain port 111 is provided in the radial direction. Here, if the angle of inclination is too large, it becomes difficult to keep the inside of the reagent cool box uniformly cold, so it is desirable to set the angle to 10 degrees or less. Even if there is no such inclination, it is possible to drain the dew condensation water on the bottom wall by the sliding contact body described later, but the presence of this inclination enhances the drainage efficiency.

図８は、図２に示した試薬保冷庫のＢ−Ｂ断面を示す図であり、図９は、同Ｂ−Ｂ断面の斜視図である。図５〜図９に示すように、試薬ディスク８の下面には、保持具１０６が設けられている。この保持具１０６は、摺接体１１０を固定するための摺接体固定具１０９と、軸１０８を介して連結されている。つまり、摺接体固定具１０９が、滑節点を介して保持具１０６に取付けられているので、摺接体１１０は試薬ディスク８に対して図５の矢印１１２に示す回転方向に、自由に回転できる。このため、図８に示すように、試薬保冷庫の底壁上面に加工精度のバラツキ等に起因してうねり（凹凸）１１３が存在する場合でも、うねり１１３に対して摺接体１１０が追従動作する。その結果、試薬ディスク８の回転抵抗を増大させることなく、摺接体１１０の下端が試薬保冷庫の底壁上面と接しながら試薬ディスク８と共に回転して結露水をかき集めることができる。 FIG. 8 is a view showing a BB cross section of the reagent cool box shown in FIG. 2, and FIG. 9 is a perspective view of the BB cross section. As shown in FIGS. 5 to 9, a holder 106 is provided on the lower surface of the reagent disc 8. The holder 106 is connected to the sliding contact fixing tool 109 for fixing the sliding contact body 110 via a shaft 108. That is, since the sliding contact body fixture 109 is attached to the holder 106 via the sliding point, the sliding contact body 110 freely rotates with respect to the reagent disc 8 in the rotation direction shown by the arrow 112 in FIG. it can. Therefore, as shown in FIG. 8, even when the swell (unevenness) 113 is present on the upper surface of the bottom wall of the reagent cooler due to variations in processing accuracy or the like, the sliding contact body 110 follows the swell 113. To do. As a result, the lower end of the sliding contact body 110 can rotate together with the reagent disc 8 while being in contact with the upper surface of the bottom wall of the reagent cold storage, and the condensed water can be collected without increasing the rotational resistance of the reagent disc 8.

なお、摺接体固定具１０９の保持具１０６に対する回転方向は、図５の矢印１１２に示す回転方向と異なる方向であっても良いし、多軸の回転であっても良い。また、本実施例では、摺接体１１０が軸１０８を介して試薬ディスク８に取付ける構成としたが、これに限らない。例えば、摺接体１１０をボールジョイントによって試薬ディスク８に取付けたり、摺接体１１０自体を樹脂やゴムなどの弾性体で形成したり、することで代用可能である。 The rotation direction of the sliding contact fixture 109 with respect to the holder 106 may be different from the rotation direction shown by the arrow 112 in FIG. 5, or may be a multi-axis rotation. Further, in this embodiment, the sliding contact body 110 is attached to the reagent disc 8 via the shaft 108, but the present invention is not limited to this. For example, the sliding contact body 110 can be attached to the reagent disc 8 by a ball joint, or the sliding contact body 110 itself can be formed of an elastic body such as resin or rubber.

図１０は、図３に示した試薬保冷庫のＣ−Ｃ断面を示す図である。図１０に示すように、本実施形態の摺接体１１０の両側部（摺接体１１０の内径側部１１０ａ及び外径側部１１０ｂ）は、試薬ディスク８の径方向Ｒに対して所定の傾斜角θを成し、かつ、略Ｖ字状に配置される。このため、排水口１１１と径方向位置の異なる場所にある結露水も、試薬ディスク８の回転に伴って結露水が次第に径方向にも移動する。例えば、排水口１１１よりも内径側に発生した結露水は、試薬ディスク８を時計回りに回転させることで、摺接体１１０の内径側部１１０ａによって外径側へ誘導され、傾斜のない中央部１１０ｃに達する。その後、この径方向位置で１周する間に、結露水が排水口１１１の位置に来て落下する。同様に、排水口１１１よりも外径側に発生した結露水は、試薬ディスク８を時計回りに回転させることで、摺接体１１０の外径側部１１０ｂによって内径側へ誘導され、最終的に排水口１１１から排出される。 FIG. 10 is a diagram showing a CC cross section of the reagent cool box shown in FIG. As shown in FIG. 10, both side portions (inner diameter side portion 110a and outer diameter side portion 110b of the sliding contact body 110) of the sliding contact body 110 of the present embodiment have a predetermined inclination with respect to the radial direction R of the reagent disk 8. It forms an angle θ and is arranged in a substantially V shape. Therefore, even if the dew condensation water is located at a position different in the radial direction from the drain port 111, the dew condensation water gradually moves in the radial direction as the reagent disk 8 rotates. For example, the condensed water generated on the inner diameter side of the drain port 111 is guided to the outer diameter side by the inner diameter side portion 110a of the sliding contact body 110 by rotating the reagent disk 8 clockwise, and is guided to the outer diameter side at the central portion without inclination. It reaches 110c. After that, while making one round at this radial position, the condensed water comes to the position of the drain port 111 and falls. Similarly, the condensed water generated on the outer diameter side of the drain port 111 is guided to the inner diameter side by the outer diameter side portion 110b of the sliding contact body 110 by rotating the reagent disk 8 clockwise, and finally. It is discharged from the drain port 111.

このように、試薬保冷庫の底壁上面と摺接体１１０との摺接部が、試薬ディスク８の径方向Ｒに対して所定の傾斜角θを成すようにすることで、排水口１１１が試薬保冷庫の底壁の任意の場所にあっても、結露水を排水口１１１へ集めることができる。ただし、傾斜角が小さ過ぎると、結露水を排水口１１１へ集めるのに時間を要してしまうので、傾斜角は３０度以上が望ましい。一方、傾斜角が大き過ぎると、摺接体１１０が長くなってしまうので、傾斜角は６０度以下が望ましい。 In this way, the drainage port 111 is formed by making the sliding contact portion between the upper surface of the bottom wall of the reagent cold storage and the sliding contact body 110 form a predetermined inclination angle θ with respect to the radial direction R of the reagent disk 8. Condensation water can be collected at the drain outlet 111 at any location on the bottom wall of the reagent cold storage. However, if the inclination angle is too small, it takes time to collect the condensed water to the drain port 111, so the inclination angle is preferably 30 degrees or more. On the other hand, if the inclination angle is too large, the sliding contact body 110 becomes long, so the inclination angle is preferably 60 degrees or less.

なお、摺接体１１０を試薬ディスク８の下面側に固定する際に、摺接体固定具１０９の形状等に起因して、摺接体１１０の中央部１１０ｃには、試薬ディスク８の径方向と平行となる部分が形成される。従って、この中央部１１０ｃの水平方向寸法は、排水口１１１の直径よりも小さくし、この中央部１１０ｃを、排水口１１１の径方向領域内に収まるように配置する。これにより、摺接体１１０の中央部１１０ｃがかき集めた結露水も、排水口１１１へ案内することが可能となっている。 When fixing the sliding contact body 110 to the lower surface side of the reagent disk 8, due to the shape of the sliding contact body fixing tool 109 or the like, the central portion 110c of the sliding contact body 110 is in the radial direction of the reagent disk 8. A portion parallel to is formed. Therefore, the horizontal dimension of the central portion 110c is made smaller than the diameter of the drainage port 111, and the central portion 110c is arranged so as to be within the radial region of the drainage port 111. As a result, the condensed water collected by the central portion 110c of the sliding contact body 110 can also be guided to the drain port 111.

また、試薬保冷庫の底壁上面に、排水口１１１に向けて下る傾斜が径方向に設けられている場合には、摺接体１１０の下端部についても、この底壁上面の傾斜に沿うように径方向の傾斜が形成される。 Further, when the upper surface of the bottom wall of the reagent cool box is provided with an inclination downward toward the drain port 111 in the radial direction, the lower end portion of the sliding contact body 110 is also provided along the inclination of the upper surface of the bottom wall. A radial slope is formed in.

図１１は、実施例２に係る試薬保冷庫における断面図（実施例１の図１０に対応する断面図）である。実施例２では、摺接体１１０の内径側部１１０ａが、実施例１と逆の向きに傾斜している。つまり、本実施形態の摺接体１１０の両側部は、内径側部１１０ａと外径側部１１０ｂとが、連続的に同じ向きに傾斜している。このため、排水口１１１よりも内径側に発生した結露水を排出する場合には、試薬ディスク８を反時計回りに回転させると、結露水を効率的に排水口１１１まで誘導できる。 FIG. 11 is a cross-sectional view of the reagent cold storage according to Example 2 (cross-sectional view corresponding to FIG. 10 of Example 1). In the second embodiment, the inner diameter side portion 110a of the sliding contact body 110 is inclined in the direction opposite to that of the first embodiment. That is, on both side portions of the sliding contact body 110 of the present embodiment, the inner diameter side portion 110a and the outer diameter side portion 110b are continuously inclined in the same direction. Therefore, when the condensed water generated on the inner diameter side of the drain port 111 is discharged, the condensed water can be efficiently guided to the drain port 111 by rotating the reagent disk 8 counterclockwise.

図１２は、実施例３に係る試薬保冷庫における断面図（実施例１の図１０、実施例２の図１１、に対応する断面図）である。実施例３の摺接体１１０は、内径側において、試薬ディスク８の径方向Ｒに対して傾斜する向きの異なる２つの内径側部１１０ａ１，１１０ａ２が形成され、外径側において、試薬ディスク８の径方向Ｒに対して傾斜する向きの異なる２つの外径側部１１０ｂ１，１１０ｂ２が形成されている。このため、本実施例の摺接体１１０は、試薬ディスク８をどちらの向きに回転させても、結露水を排水口１１１まで誘導できる利点がある。 FIG. 12 is a cross-sectional view of the reagent cold storage according to Example 3 (cross-sectional view corresponding to FIG. 10 of Example 1 and FIG. 11 of Example 2). In the sliding contact body 110 of Example 3, two inner diameter side portions 110a1 and 110a2 having different directions of inclination with respect to the radial direction R of the reagent disk 8 are formed on the inner diameter side, and the reagent disk 8 is formed on the outer diameter side. Two outer diameter side portions 110b1 and 110b2 having different directions of inclination with respect to the radial direction R are formed. Therefore, the sliding contact body 110 of this embodiment has an advantage that the condensed water can be guided to the drain port 111 regardless of which direction the reagent disk 8 is rotated.

図１３は、実施例４に係る試薬保冷庫における、吸引孔１０４と排水口１１１の位置関係を示す平面図（実施例１の図２に対応する平面図）である。外気は吸引孔１０４から試薬保冷庫内に流入するため、この吸引孔１０４に近い場所が結露し易い。そこで、本実施例では、試薬ディスク８の回転軸に対して偏芯した位置にある吸引孔１０４の真下に、排水口１１１を形成することで、試薬保冷庫の底壁に発生する結露を効率的に排出するようにしている。 FIG. 13 is a plan view (plan view corresponding to FIG. 2 of Example 1) showing the positional relationship between the suction hole 104 and the drain port 111 in the reagent cold storage according to the fourth embodiment. Since the outside air flows into the reagent cold storage through the suction hole 104, dew condensation is likely to occur in a place near the suction hole 104. Therefore, in this embodiment, by forming the drain port 111 directly under the suction hole 104 at a position eccentric with respect to the rotation axis of the reagent disk 8, the dew condensation generated on the bottom wall of the reagent cold storage is efficiently eliminated. I try to discharge it.

ただし、排水口１１１が吸引孔１０４の真下でなくても、試薬ディスク８の回転軸に対して、吸引孔１０４と同じ側に偏芯した位置に排水口１１１があれば、一定の排出効果が期待できる。つまり、図１３のように、吸引孔１０４と試薬ディスク８の回転軸Ｏとを結ぶ線と垂直な直線Ｈを基準として、試薬保冷庫の底壁を２つの半円の領域に分けた場合、吸引孔１０４の存在する半円の領域内に、排水口１１１が位置するようにすれば、一定の排出効果が期待できる。 However, even if the drain port 111 is not directly below the suction hole 104, if the drain port 111 is located at a position eccentric to the same side as the suction hole 104 with respect to the rotation axis of the reagent disc 8, a certain drainage effect can be obtained. You can expect it. That is, as shown in FIG. 13, when the bottom wall of the reagent cold storage is divided into two semicircular regions with reference to a straight line H perpendicular to the line connecting the suction hole 104 and the rotation axis O of the reagent disk 8. If the drain port 111 is located in the semicircular region where the suction hole 104 exists, a certain discharge effect can be expected.
