Abstract

Disclosed is a contact cover used for an incubator for observation by microscope. The contact cover can prevent the formation of spaces between the inner surface of a lens insertion hole and object lens, allows precise management of temperature, humidity and the like of the environment in the space accommodating samples, and does not require the production of a sliding contact cover with different dimensions of lens insertion hole diameter for each diameter dimension of object lens. Also disclosed is an incubator for observation by microscope provided with that sliding contact cover. A sheet (5) for a sliding contact cover (3) is formed from silicone rubber, which is a transparent material, and is flexible. This sheet (5) has a thin disc shape, and a circular lens insertion hole (7) is formed in the center thereof. An object lens (T) is inserted into the lens insertion hole (7). Since the sheet (5) is flexible, the diameter of the lens insertion hole (7) is expanded slightly by the lens barrel of the object lens (T), and the inner surface of the lens insertion hole (7) adheres to the outer surface of the lens barrel of the object lens (T). The state is such that no space is formed between the inner surface of the lens insertion hole (7) and the object lens (T).

　細胞等の観察試料を培養するためには、温度、湿度等の環境を管理する必要がある。顕微鏡のステージに載せた状態で温度、湿度等の環境を管理して細胞等の観察試料を培養し、この状態を観察することができる顕微鏡観察用培養器があり、この種の顕微鏡観察用培養器には特許文献１に記載されたものがある。
　この顕微鏡観察用培養器は、観察試料が収容される試料収容空間を有する培養器本体を備えており、この培養器本体の上面（蓋体）には試料収容空間に連通する穴が形成されている。培養器本体の上面には、上記穴を覆う状態に顕微鏡観察用培養器に用いる摺接カバーが載置されている。この摺接カバーはガラス等の硬質材料から成り、摺接カバーには対物レンズが挿入されるレンズ挿入穴が形成されている。 In order to culture an observation sample such as a cell, it is necessary to manage the environment such as temperature and humidity.

　しかしながら、従来の顕微鏡観察用培養器では、上記したように摺接カバーが硬質材料から成っているので、レンズ挿入穴を対物レンズの径寸法よりも一回り大きく形成する必要がある。このため、レンズ挿入穴の内周面と対物レンズとの間にはどうしても隙間ができてしまい、試料収容空間内の温度、湿度等の環境を高精度に管理することが難しい。
　また、対物レンズは、倍率などの違いにより径寸法の異なるものが複数種類あるため、対物レンズの径寸法ごとにレンズ挿入穴の径寸法が異なる摺接カバーを製作する必要があり、摺接カバーの種類が多くなってしまう。 However, in the conventional incubator for microscope observation, since the sliding contact cover is made of a hard material as described above, it is necessary to form the lens insertion hole slightly larger than the diameter dimension of the objective lens. For this reason, a gap is inevitably formed between the inner peripheral surface of the lens insertion hole and the objective lens, and it is difficult to manage the environment such as temperature and humidity in the sample storage space with high accuracy.
In addition, since there are multiple types of objective lenses with different diameters due to differences in magnification, etc., it is necessary to manufacture a sliding contact cover in which the diameter dimension of the lens insertion hole is different for each objective lens diameter. There will be more types.

Can be managed with high accuracy, and there is no need to produce a sliding cover in which the diameter of the lens insertion hole differs for each diameter of the objective lens. It is an object of the present invention to provide a microscopic observation incubator provided with a contact cover.

　試料収容空間２１には図示しないガス供給装置によってＣＯ２ガス等が供給されるようになっており、また、水槽１９には図示しない給水装置によって水が供給されるようになっている。 The lid body 23 includes a lid plate portion 25 having an opening 27 and a transparent glass heater 29 fitted in the opening 27. A round hole 31 is formed at the center of the transparent glass heater 29, and the round hole 31 is set to have a diameter smaller than the outer diameter of the sliding contact cover 3 and larger than the lens insertion hole 7.
CO2 gas or the like is supplied to the sample storage space 21 by a gas supply device (not shown), and water is supplied to the water tank 19 by a water supply device (not shown).
　符号３３はヒータープレートを示し、このヒータープレート３３は枠体３５と、この枠体３５に嵌められた透明ガラスヒーター３７によって構成されている。
　環境管理手段は水槽１９、透明ガラスヒーター２９、図示しないガス供給装置、図示しない給水装置及び透明ガラスヒーター３７によって構成されている。 Reference numeral 33 denotes a heater plate, and the heater plate 33 includes a frame body 35 and a transparent glass heater 37 fitted to the frame body 35.
The environmental management means includes a water tank 19, a transparent glass heater 29, a gas supply device (not shown), a water supply device (not shown), and a transparent glass heater 37.
　図１において符号３９は顕微鏡のステージを示し、このステージ３９は、上下に重ねて配置された二枚の駆動板４１、４３を備えている。上側の駆動板４１は左右方向（ａ－ｂ方向）へ水平駆動し、下側の駆動板４３は上側の駆動板４１と共に前後方向（ｃ－ｄ方向）へ水平駆動する。また、駆動板４１、４３は上下方向（ｅ－ｆ方向）へ駆動するようになっている。駆動板４１、４３には開口４５が形成されている（図３参照）。 In FIG. 1, reference numeral 39 denotes a microscope stage, and the stage 39 includes two drive plates 41 and 43 arranged one above the other. The upper drive plate 41 is horizontally driven in the left-right direction (ab direction), and the lower drive plate 43 is horizontally driven in the front-rear direction (cd direction) together with the upper drive plate 41. The drive plates 41 and 43 are driven in the vertical direction (ef direction). Openings 45 are formed in the drive plates 41 and 43 (see FIG. 3).
　次に、顕微鏡観察用培養器１の使用方法について説明する。
　図３に示すようにヒータープレート３３を駆動板４１の開口４５に嵌めて、開口４５を塞ぐ。そして、ヒータープレート３３上に試料収容空間２１が位置するようにベース部１７を駆動板４１に載せる。次に、細胞等の観察試料Ｓを培養液と共にディッシュＤに入れ、このディッシュＤを試料収容空間２１に収容する。次いで、蓋体２３をベース部１７に載置してベース部１７の上面開口を覆う状態とする。この状態では、蓋体２３の丸穴３１は試料収容空間２１に連通している。
　摺接カバー３を蓋体２３の透明ガラスヒーター２９に載置して、この摺接カバー３によって丸穴３１を覆い、レンズ挿入穴７を丸穴３１に対応させる。
　前述したように摺接カバー３のシート５は透明材料から成っているので、試料収容空間２１に収容された観察試料Ｓを外部から視認可能になっている。 Next, a method for using the microscopic observation incubator 1 will be described.
As shown in FIG. 3, the heater plate 33 is fitted into the opening 45 of the drive plate 41 to close the opening 45. Then, the base portion 17 is placed on the drive plate 41 so that the sample accommodation space 21 is positioned on the heater plate 33. Next, the observation sample S such as cells is placed in the dish D together with the culture solution, and the dish D is stored in the sample storage space 21. Next, the lid body 23 is placed on the base portion 17 to cover the upper surface opening of the base portion 17. In this state, the round hole 31 of the lid body 23 communicates with the sample storage space 21.
The sliding contact cover 3 is placed on the transparent glass heater 29 of the lid 23, the round hole 31 is covered with the sliding contact cover 3, and the lens insertion hole 7 is made to correspond to the round hole 31.
As described above, since the sheet 5 of the sliding contact cover 3 is made of a transparent material, the observation sample S accommodated in the sample accommodation space 21 can be visually recognized from the outside.
　次に、対物レンズＴをレンズ挿入穴７に挿入する。前述したようにシート５は柔軟性を有しているので、レンズ挿入穴７は対物レンズＴの鏡筒によって僅かに拡径され、レンズ挿入穴７の内周面が対物レンズＴの鏡筒の外周面に密着する。従って、レンズ挿入穴７の内周面と対物レンズＴとの間には隙間がない状態となる。
　また、レンズ挿入穴７に挿入した対物レンズＴは、丸穴３１から試料収容空間２１へ入り込んだ状態となっている。
　試料収容空間２１はベース部１７、蓋体２３、摺接カバー３、対物レンズＴ、ヒータープレート３３及び駆動板４１によって画成された空間となる。 Next, the objective lens T is inserted into the lens insertion hole 7. As described above, since the sheet 5 has flexibility, the lens insertion hole 7 is slightly enlarged in diameter by the lens barrel of the objective lens T, and the inner peripheral surface of the lens insertion hole 7 is the lens barrel of the objective lens T. Close contact with the outer peripheral surface. Therefore, there is no gap between the inner peripheral surface of the lens insertion hole 7 and the objective lens T.
Further, the objective lens T inserted into the lens insertion hole 7 is in a state of entering the sample accommodation space 21 from the round hole 31.
The sample storage space 21 is a space defined by the base portion 17, the lid body 23, the sliding contact cover 3, the objective lens T, the heater plate 33, and the drive plate 41.
　次いで、透明ガラスヒーター２９、３７、図示しないガス供給装置及び図示しない給水装置によって、試料収容空間２１内の温度、湿度等の環境を所定の状態に管理する。上記したようにレンズ挿入穴７の内周面と対物レンズＴとの間には隙間がないので、試料収容空間２１を外部と略完全に隔絶でき、試料収容空間２１内の温度、湿度等の環境を高精度に管理することが可能である。 Next, the environment such as temperature and humidity in the sample storage space 21 is managed in a predetermined state by the transparent glass heaters 29 and 37, a gas supply device (not shown), and a water supply device (not shown). As described above, since there is no gap between the inner peripheral surface of the lens insertion hole 7 and the objective lens T, the sample storage space 21 can be substantially completely isolated from the outside, and the temperature, humidity, etc. in the sample storage space 21 can be determined. It is possible to manage the environment with high accuracy.
　観察試料Ｓの観察位置を変更する場合には、ステージ３９の駆動板４１、４３と共に培養器本体１５を水平方向へ動作させる。前述したようにシート５の下面はフレーム９の下面よりも上方に位置しているので、シート５は透明ガラスヒーター２９に摺接せず、フレーム９だけが透明ガラスヒーター２９に摺接する。従って、透明ガラスヒーター２９の上面、即ち培養器本体１５の上面はフレーム９の下面に対しスムーズに摺動する。 When changing the observation position of the observation sample S, the incubator body 15 is moved in the horizontal direction together with the drive plates 41 and 43 of the stage 39. As described above, since the lower surface of the sheet 5 is located above the lower surface of the frame 9, the sheet 5 does not slide on the transparent glass heater 29, and only the frame 9 slides on the transparent glass heater 29. Therefore, the upper surface of the transparent glass heater 29, that is, the upper surface of the incubator body 15 slides smoothly with respect to the lower surface of the frame 9.
　対物レンズＴの焦点を合わせるため、ステージ３９の駆動板４１、４３と共に培養器本体１５を上下方向へ動作させる。前述したようにシート５は柔軟性を有しているので、図４に示すようにシート５は培養器本体１５の上下方向の動作に応じて伸縮する。従って、レンズ挿入穴７の内周面は対物レンズＴの鏡筒に対し密着した状態を保つことができる。よって、レンズ挿入穴７の内周面と対物レンズＴとの間に隙間ができるのを確実に防止できる。
　また、図５に示すように対物レンズＴを上下方向へ動作させる場合でも、上記と同様にシート５は対物レンズＴの上下方向の動作に応じて伸縮する。従って、レンズ挿入穴７の内周面は対物レンズＴの鏡筒に対し密着した状態を保つことができ、レンズ挿入穴７の内周面と対物レンズＴとの間に隙間ができるのを確実に防ぐことが可能である。 In order to focus the objective lens T, the incubator body 15 is moved in the vertical direction together with the drive plates 41 and 43 of the stage 39. Since the sheet 5 has flexibility as described above, the sheet 5 expands and contracts according to the vertical movement of the incubator body 15 as shown in FIG. Therefore, the inner peripheral surface of the lens insertion hole 7 can be kept in close contact with the lens barrel of the objective lens T. Therefore, it is possible to reliably prevent a gap from being formed between the inner peripheral surface of the lens insertion hole 7 and the objective lens T.
Further, as shown in FIG. 5, even when the objective lens T is moved in the vertical direction, the sheet 5 expands and contracts according to the vertical movement of the objective lens T as described above. Accordingly, the inner peripheral surface of the lens insertion hole 7 can be kept in close contact with the lens barrel of the objective lens T, and it is ensured that a gap is formed between the inner peripheral surface of the lens insertion hole 7 and the objective lens T. It is possible to prevent.
　また、シート５は柔軟性を有しており、このシート５のレンズ挿入穴７は、ある程度の径寸法まで拡径可能となっているので、一つの摺接カバー３で径寸法の異なる複数種類の対物レンズＴに対応することができる。従って、対物レンズＴの径寸法ごとにレンズ挿入穴７の径寸法が異なる摺接カバー３を製作する必要がなくなる。 Further, since the sheet 5 has flexibility and the lens insertion hole 7 of the sheet 5 can be expanded to a certain diameter, a plurality of types having different diameters by one sliding contact cover 3 are provided. It is possible to correspond to the objective lens T. Therefore, it is not necessary to manufacture the sliding cover 3 in which the diameter dimension of the lens insertion hole 7 is different for each diameter dimension of the objective lens T.
　以上、本発明の実施の形態について詳述してきたが、具体的構成は、この実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲における設計の変更などがあっても発明に含まれる。
　上記実施の形態では、シート５をシリコーンゴムによって構成したが、シート５をウレタンゴム等によって構成してもよい。
　また、フレーム９をリング状に形成したが、フレームの形状はリング状に限定されず、例えば、フレーム９を矩形状に形成してもよい。
　さらに、フレーム９をプラスチックによって構成したが、フレーム９を木材やガラス等によって構成してもよい。 The embodiment of the present invention has been described in detail above.

In the above embodiment, the sheet 5 is made of silicone rubber, but the sheet 5 may be made of urethane rubber or the like.
Further, although the frame 9 is formed in a ring shape, the shape of the frame is not limited to the ring shape, and for example, the frame 9 may be formed in a rectangular shape.
Furthermore, although the frame 9 is made of plastic, the frame 9 may be made of wood or glass.
