Description

【0001】
【産業上の利用分野】
この発明は、顕微鏡標本に作製しようとする試料をスライドガラスに貼着し、染色し、封入剤(接着剤)を加えた後、薄いカバーガラスを重ねて顕微鏡標本を作製する際に、多数のカバーガラスを重ねたカバーガラスブロックからカバーガラスを1枚ずつ取出す操作、及びスライドガラスへカバーガラスを取付ける操作を確実にかつ能率よく行なえるカバーガラス取出し及び取付け方法に関する。
【0002】
【従来の技術】
積重ねられたカバーガラスのブロックから、カバーガラスを1枚ずつを取出し、これを試料、封入剤を覆ってスライドガラスに取付ける際には、次の点に留意しなければならない。
【0003】
(1) カバーガラスは、厚さ0.01〜0.1mm程度の極めて薄いガラス板を数百枚重ねブロック状にして市販されている。使用時には、このガラス板のブロックをケースに入れ、ガラス板の重なりから1枚ずつ取出すのであるが、薄いガラス板は互いに強固に密着状態となっているので、ガラス板を破損させることなく1枚ずつ取出すのは容易ではない。
【0004】
(2) 又、カバーガラスを試料及び封入剤を覆ってスライドガラスに重ねるときに、両ガラス板の間に空気(気泡)が残ると、顕微鏡観察を阻害するので、気泡の残留をなくさなければならない。
【0005】
これらの点を解決するために、従来から種々の方法が考えられている。それらの主なものを図9〜図16により次に例示する。
【0006】
実開昭61−176434号公報に記載された方法は、図9に略示するように、積重ねられたカバーガラス1、1の端面をフェルト片2で抑え、最上層のカバーガラス1aを吸着パット3で吸引し上昇させることにより最上層のカバーガラス1aのみを持上げ、他のカバーガラスはフェルト片2とガラス端面との摩擦により抑えて持上げられないようにしてカバーガラスを最上層から1枚ずつ取出すものである。
【0007】
特開昭59−157535号公報に記載された方法は、図10(側面図)、図11(正面図)に略示するように、支持板4の上に底の開いたケース(ストッカ)5を載せ、その前壁5aと支持板4との間に、カバーガラス1枚のみを通過させる隙間6を設け、上面が支持板4の上面に一致し支持板4から出入する吸着具7を設けたもので、吸着具7で最下層のカバーガラス1bを吸着しつつ吸着具7を支持板4から左方へ進出させることにより最下層のカバーガラス1bのみを隙間6を通過させて取出すものである。
【0008】
実開昭57−191736号公報に記載された方法は、図12、図13(共に側面図)に略示するように、ブロック状に積重ねられたカバーガラス1の最上層のカバーガラス1aの両端を吸着する2個の吸着パッド3、3の間に押圧体8を設け、押圧体8を支持するねじ棒9を操作して、先ず図12のように吸着パット3、3、押圧体8を最上層のカバーガラス1aの表面に均等に当接させた後、図13のように両端のパットを少し持上げて最上層のカバーガラス1aを下方凸に湾曲させ、次層のカバーガラス1cとの間に間隙を生じさせて空気を進入させ、最上層のカバーガラスを次層のカバーガラス1cから分離して持上げるものである。このカバーガラスをスライドガラスに重ねるときは、カバーガラスを下方凸に湾曲させた状態のままスライドガラスに重ね、吸着パット3、3の吸着を解除して下方凸の湾曲を水平状態に戻し、このようにして空気をカバーガラスとスライドガラスとの中央部から両側方へ押出して気泡残留を防いでいる。
【0009】
実開昭58−30636号公報に記載された方法は、図14に略示するように、最上層のカバーガラス1aの1端部を押圧体8で抑え、他端部を吸着パット3で吸引し持上げてカバーガラスを下方凸に湾曲させることにより、最上層のカバーガラス1aを次層のカバーガラス1cから分離するものである。
【0010】
このようにカバーガラスの1端を持上げてから、空気を押出しつつカバーガラスをスライドガラスに重ねる方法は、特公平3−40367号公報にも記載されている。
【0011】
実開昭61−56620号公報には、図15に略示するような、カバーガラスを試料を挟んでスライドガラスに重ねるときに、気泡を残さないための方法が記載されている。この方法は、吸着パット3で保持したカバーガラス1を、スライドガラス10に上方から近づけ、その1端を係止片11に引掛けて下降を停止させ、他端はスライドガラス10に押付けてカバーガラスを下方凸に湾曲させ、次に係止片11を引込めてこれに支えられていたカバーガラス端を解放する方法である。カバーガラスは右端部からスライドガラスに接近し、両ガラスの間の空気を左方へ押出す。12は試料、13は封入剤を示す。
【0012】
実開昭61−193354号公報に記載された方法(図16)は、図15に示したカバーガラス端の係止を、カバーガラスの両端に設けた揺動係止片14によって行ない、カバーガラスの中央を下圧してこれを下方凸に弾性変形させて空気を排出しつつカバーガラスをスライドガラスに重ねるものである。
【0013】
【発明が解決しようとする課題】
上記の従来方法において、図9に略示した端面をフェルトで抑える方法は、フェルトが摩耗すると抑えが不確実になり、又フェルトの細片がカバーガラスに付着し、そのまま標本に封入されてしまう危険がある。こうなると標本の検査に重大な悪影響を及ぼすことになる。
【0014】
図10、図11に示した方法では、市販のカバーガラスの厚さには多くの種類があるため、カバーガラスを通す隙間6を一定にすると、厚さの異なるカバーガラスの取出しができなくなるので、ケース前壁を隙間の異なるものと交換できるようにしなければならない。又、重なったカバーガラスは、強く密着しているので、これを摺動させることが困難である。
【0015】
図12〜図16に略示した方法は、装置が複雑になるのを避けられない。
【0016】
【課題を解決するための手段】
積重ねられたカバーガラスブロックの最上層のものを下方凸に湾曲させ、側方から空気を進入させて次層のカバーガラスから剥離する方法は、最上層のカバーガラス取出しを確実に行ない得させるので有効である。又、カバーガラスをスライドガラスに向けて凸に弾性変形させた状態でスライドガラスに接触させ、変形を回復させて両ガラスの間に介在する空気を側方へ排除しつつカバーガラスをスライドガラスに重ねる方法は、空気排除作用が確実である。
【0017】
そこで本発明は、カバーガラスを湾曲させてカバーガラスブロックから取出し、湾曲状態でスライドガラスに重ねる方法を採用すると共に、簡単な機構でこれが実施できるように考えたものである。
【0018】
即ち本発明の方法は、水平軸を中心として回動自在な腕に吸着パットを取付けた装置を使用して、積重ねられたカバーガラスのブロックから最上層のカバーガラスを取出すときは、最上層カバーガラスの腕の回動中心から遠い1端部をパットで吸着して腕を上方に回動させると共に他端の自由端を次層のカバーガラスに押当てて最上層カバーガラスを下方凸に弾性湾曲させ、最上層及び次層のカバーガラスの間に空気を進入させて両カバーガラスを剥離し、カバーガラスをスライドガラスに重ねるときは、自由端を下にして吸着パットにより傾斜状態で吊下げられたカバーガラスを、自由端を先ずスライドガラスに当接させ、次いで腕を上記と逆方向に回動させてカバーガラスを下方凸に弾性湾曲させ、吸着端をスライドガラスに近づけ、空気を排除しつつカバーガラスをスライドガラスに重ねるものである。
【0019】
【作用】
カバーガラスのブロックから前記のようにして最上層のカバーガラスを取出すと、最上層のカバーガラスは腕の回動により吸着端を持上げられるが、自由端は次層カバーガラスに拘束されるので、下方凸に弾性湾曲し空気が進入して両カバーガラスは剥離され、最上層カバーガラスを容易に取出すことができる。
【0020】
又このカバーガラスをスライドガラスに取付けるときは、水平軸を中心として回動自在な腕に取付けた吸着パットでカバーガラスの1端部を吸着し、自由端を下にして傾斜した状態で吊下げたカバーガラスの自由端を、腕を回動してカバーガラスに当接させ、カバーガラスをスライドガラスに向けて凸に弾性湾曲させつつスライドガラスに近づけるから、カバーガラスとスライドガラスとの間の空気はパットに吸着された側に押出されて、空気を残留させることなく、カバーガラスをスライドガラスに重ねることができる。
【0021】
このように作用させるためにカバーガラスケース、スライドガラス、吸着パットを相対的に移動させる手段は、種々のものが考えられるが、何れも通常の機構により容易に構成でき、カバーガラスのブロックからカバーガラスを1枚ずつ取出したり、取出したカバーガラスを気泡を残すことなくスライドガラスに重ねることを確実に行なうことができる。
【0022】
【実施例】
図1は本発明の顕微鏡標本のカバーガラス取付け方法を行なうための装置の要領を示す略側面図、図2はカバーガラスのブロックから最上層の1枚を取出す状況を示す略側面図、図3〜図5はこのカバーガラスをスライドガラスに重ねて取付ける状況を示す略側面図、図6は腕の別の構成例を示す側面図、図7はこれの平面図、図8はカバーガラスをカバーガラスブロックの直下のスライドガラスに重ねる別の構成例を略示する側面図で、(a)〜(c)はその途中段階を示す。前述の従来例と同等部分は同符号を用いて示すと共に説明を省略して、次にこれを説明する。
【0023】
図1において、支持板15に載せたカバーガラス1、1のブロックを入れたケース5のカバーガラスの1端部上方に、腕16に支持された吸着パット3が位置する。パット3を下端に取りつけた支持棒17は、腕16に縦動自在に嵌合し、上端に、吸着パット内を真空ポンプに接続する可撓性のパイプ18を連結し、パット3と腕16との間には緩衝用の圧縮ばね19を介装している。腕16は支柱20に沿って昇降できるスリーブ21に水平な軸22を中心として時計方向及び反時計方向にモータ23に駆動されて回動自在である。スリーブ21は、モータ24の回転により支柱20に形成したラック20aと図示しない歯車との噛合により昇降する。支柱20は、台25の上に回動自在に支持され、台25には、試料12を貼着、染色したスライドガラス10が置かれ、これにはノズル26により封入剤13を滴下する。
【0024】
支持板15に載せたケース5に入れたカバーガラスブロックの最上層のカバーガラス1aを取出すには、先ずスリーブ21を支柱20に沿い下降させて、パット3の下縁のなす平面を水平にして最上層カバーガラス1aの左端部に当接させ、カバーガラスを吸引する。次にこの状態においてモータ23を回転させて腕16を時計方向に少し回動させる。これによりパット下縁のなす平面が上昇しつつ右下がりに傾斜するから、これに合せてスリーブ21を少し下降させ(又は支持板15を少し上昇させ)ると、最上層カバーガラス1aは図2のように右端を次層のカバーガラス1cに衝き当てて下方凸に湾曲する。これにより最上層及び次層のカバーガラスの間に空気が進入し、両カバーガラスは容易に分離する。そこでスリーブ21を上昇させ(又は支持板15を下降させ)ると共に支柱20を回動させてパット3をケース5の上方位置から外せば、最上層カバーガラス1aはパット3に吸着されたまま傾斜して空中に吊下げられる。
【0025】
次に、このように吊下げられたカバーガラス1aをスライドガラス10に重ねるには、このカバーガラス1aを、試料12を貼着され封入剤13を滴下されたスライドガラス10の上方に位置させ、スライドガラスに向けてスリーブ21を下降させ、先ず図3のように傾斜してパット3に吸着されたカバーガラス1aの下った自由端をスライドガラスの右端に当接させる。続いてスリーブ21を更に少し下降させると、図4のようにカバーガラス1aは下方凸に湾曲する。この状態で腕16を反時計方向に回動させ、最後にパット3による吸着を解除すると、カバーガラス1aはスライドガラス10との間の空気を左方へ徐々に押出しつつスライドガラス10に重なりカバーガラス取付けができる。
【0026】
上層から次々にカバーガラスを取出すと、カバーガラスブロックの厚さが小さくなるから、スリーブ21又は支持板15を昇降させて最初の状態に戻してこの操作を行う。
【0027】
カバーガラスをカバーガラスブロックから取出すときのカバーガラスの湾曲する状態は、腕16の回動中心の位置により変化する。例えば図2のように、回動中心となる軸22がカバーガラス1aの自由端とパット3との中間にある場合は、腕16の時計方向回動によりカバーガラス1aの左端、右端は共に時計方向に回動しようとして、カバーガラスの右端は次層のカバーガラスに押付けられるから、カバーガラスは下方凸に湾曲する。従って湾曲させるためにスリーブ21又は支持板15を移動させる必要はなくなる。
【0028】
図5のように腕16の回動中心の軸22がカバーガラスを外れて右方に位置すると、腕16の時計方向回動により最上層のカバーガラス1aの自由端(右端)も時計方向に回動しようとして最上層カバーガラスを下方凸に湾曲させ難くなるから、このときはスリーブ21又は支持板15を昇降させる。
【0029】
図6、図7は腕16の回動中心を上記のようにガラスの吸着端と自由端との間に位置させるための腕16等の構成を略示する。腕16の基部16aは、ケース5を挟む二又に形成し、スリーブ21からも二又のブラケット21aを突出させてケース5の側方で腕の基部16aを軸22aで枢着する。この軸22aが腕16の回転中心となる。中心位置はカバーガラスの湾曲が過度にならないように選択する。基部16aを片持ち式にすれば、基部16a及びブラケット21aを二又にしなくてもよい。
【0030】
図1の構成は、支柱20を回動させて、吸着したカバーガラスとケース5、支持板15等との衝突を避けつつカバーガラスをケース直下のスライドガラス10に重ねるようにした例であるが、図8(a)〜(c)は、支柱20を回動させないでこれを行なう構成例を略示する。
【0031】
この構成の場合の動作を次に説明すると、先ず図8(a)のように吸着パット3で最上層のカバーガラス1aの端部を吸着したならば、腕16を時計方向へ回動させて、ケース5等との衝突を避けられるように図8(b)の状態にする。この状態のままスリーブ21を下降させ、カバーガラス1aをケース5、支持板15の横を通過して下降させる。スリーブ21が十分下降したならば、図8(c)のように腕16を反時計方向に回動させてカバーガラス1aをスライドガラス10に重ねる。このようにすれば、支柱20を回動させないで装置を構成することができる。
【0032】
以上のように本発明の方法は、吸着パット3を支持する腕16を回動させることにより、カバーガラス1の腕16の回動中心から遠い端部を吸着するパット端面を傾斜させると共に、カバーガラスの自由端を次層のカバーガラス又はスライドガラスで支えてカバーガラスを弾性的に下方凸に湾曲させて、次層のカバーガラスとの間に空気を進入させて最上層のカバーガラスを取出し、又スライドガラスとの間の空気を排出してスライドガラスとの間に気泡を残溜させないでカバーガラスを取付けるものであるから、吸着パットを取付けた腕16、カバーガラスのケース5及びスライドガラスを載せる台25の位置関係や運動方式を種々に変えて目的を達することができる。
【0033】
例えば、図1において、最上層のカバーガラス1aを吸着した後、ケース5を載せる支持板15を左方へ退避させ、スリーブ21を下降させて台25に載置したスライドガラスにカバーガラスを重ねたり、支持板15は不動にして、パット3が最上層カバーガラスを吸着したならば支柱20を回動させ、腕16をケース5を避けて下降させてカバーガラスをスライドガラスに重ねたり、支柱20と台25とを結合したまま回動させて腕16とケース5との衝突を避けたり、定位置で上下に回動する腕16にケース5、スライドガラス10を別個に遠近させたり、又は前記のように腕を回動させてケース5、支持板15との衝突を避ける等の機構を組合せて本発明の方法を実施することができる。
【0034】
【発明の効果】
この発明のカバーガラス取付け方法は、カバーガラスを湾曲させて、次層のカバーガラスとの間に空気を進入させつつカバーガラスブロックから1枚ずつ取出し、これを湾曲状態で気泡の残留を防ぎつつスライドガラスに重ねる操作を、吸着パットを支持する腕の回動により行なうものであるから、これを実施するための装置が簡単であり、付随する装置も簡単に構成できて、良好な顕微鏡標本作製を能率よく行なうことができる。

[Industrial applications]
According to the present invention, when a sample to be prepared on a microscope specimen is pasted on a slide glass, stained, an encapsulant (adhesive) is added, and a thin cover glass is overlaid to prepare a microscope specimen, a large number of specimens are prepared. The present invention relates to a method for removing and attaching a cover glass that can reliably and efficiently perform an operation of taking out cover glasses one by one from a cover glass block on which cover glasses are stacked and an operation of attaching a cover glass to a slide glass.
[0002]
[Prior art]
When removing cover glasses one by one from the stacked cover glass blocks and covering them with the sample and the mounting medium, the following points must be taken into consideration.
[0003]
(1) A cover glass is commercially available in the form of a block of several hundred extremely thin glass plates having a thickness of about 0.01 to 0.1 mm. At the time of use, this glass plate block is put in a case and removed one by one from the overlap of the glass plates. However, since the thin glass plates are tightly adhered to each other, one glass plate is not damaged and It is not easy to remove them one by one.
[0004]
(2) Also, when air (bubbles) is left between the two glass plates when the cover glass covers the sample and the encapsulant and is laid on the slide glass, microscopic observation is hindered. .
[0005]
In order to solve these points, various methods have been conventionally considered. The main ones are illustrated below with reference to FIGS.
[0006]
In the method described in Japanese Utility Model Laid-Open Publication No. Sho 61-176434, as shown schematically in FIG. 9, the end faces of the stacked cover glasses 1 and 1 are held down by felt pieces 2, and the uppermost cover glass 1a is adsorbed by a suction pad. The upper cover glass 1a is lifted only by sucking and raising at 3 and the other cover glasses are prevented from being lifted by the friction between the felt piece 2 and the glass end face so that the cover glass is not lifted one by one from the uppermost layer. To take out.
[0007]
The method described in JP-A-59-157535 discloses a case (stocker) 5 having an open bottom on a support plate 4 as schematically shown in FIGS. 10 (side view) and 11 (front view). Is provided between the front wall 5 a and the support plate 4, a gap 6 for passing only one cover glass is provided, and a suction tool 7 whose upper surface coincides with the upper surface of the support plate 4 and moves in and out of the support plate 4 is provided. The suction tool 7 is moved out of the support plate 4 to the left while adsorbing the lowermost cover glass 1b by the suction tool 7, so that only the lowermost cover glass 1b passes through the gap 6 and is taken out. is there.
[0008]
The method described in Japanese Utility Model Laid-Open Publication No. 57-191736 discloses a method in which both ends of a top cover glass 1a of a cover glass 1 stacked in a block shape are schematically illustrated in FIGS. A pressing body 8 is provided between two suction pads 3 and 3 for sucking, and a screw rod 9 for supporting the pressing body 8 is operated to first move the suction pads 3 and 3 and the pressing body 8 as shown in FIG. After evenly contacting the surface of the cover glass 1a of the uppermost layer, the pads at both ends are slightly lifted as shown in FIG. A gap is formed therebetween to allow air to enter, and the top cover glass is separated from the next cover glass 1c and lifted. When the cover glass is overlaid on the slide glass, the cover glass is overlaid on the slide glass in a state where the cover glass is curved downwardly convex, the suction pads 3, 3 are released, and the downwardly convex curvature is returned to a horizontal state. In this way, air is pushed out from the center of the cover glass and the slide glass to both sides to prevent air bubbles from remaining.
[0009]
In the method described in Japanese Utility Model Application Laid-Open No. 58-30636, one end of the uppermost cover glass 1a is held down by a pressing body 8, and the other end is sucked by a suction pad 3, as schematically shown in FIG. The cover glass 1a of the uppermost layer is separated from the cover glass 1c of the next layer by lifting and bending the cover glass so as to protrude downward.
[0010]
A method in which one end of the cover glass is lifted and the cover glass is overlaid on the slide glass while extruding air is also described in Japanese Patent Publication No. 3-40367.
[0011]
Japanese Utility Model Laid-Open Publication No. 61-56620 describes a method for preventing bubbles from remaining when a cover glass is placed on a slide glass with a sample interposed therebetween, as schematically shown in FIG. In this method, the cover glass 1 held by the suction pad 3 is brought close to the slide glass 10 from above, one end of the cover glass 1 is hooked on the locking piece 11 to stop the descent, and the other end is pressed against the slide glass 10 to cover the slide glass 10. This is a method in which the glass is curved downwardly convex, and then the locking piece 11 is retracted to release the end of the cover glass supported by the locking piece. The cover glass approaches the slide glass from the right end and pushes the air between the two glasses to the left. Reference numeral 12 denotes a sample, and 13 denotes an encapsulating agent.
[0012]
In the method described in Japanese Utility Model Laid-Open Publication No. 61-193354 (FIG. 16), the ends of the cover glass shown in FIG. 15 are locked by swing locking pieces 14 provided at both ends of the cover glass. The cover glass is superimposed on the slide glass while the air is exhausted by applying a downward pressure to the center of the slide glass and elastically deforming it downward.
[0013]
[Problems to be solved by the invention]
In the above-mentioned conventional method, the method of holding the end face shown in FIG. 9 with felt is uncertain if the felt is worn, and a small piece of felt adheres to the cover glass and is directly enclosed in the specimen. There is danger. This would have a serious adverse effect on specimen inspection.
[0014]
In the methods shown in FIGS. 10 and 11, since there are many types of thicknesses of commercially available cover glasses, if the gap 6 through which the cover glass is passed is made constant, it becomes impossible to take out cover glasses having different thicknesses. In addition, the front wall of the case must be exchanged for one having a different gap. In addition, since the overlapped cover glasses are strongly adhered, it is difficult to slide them.
[0015]
The methods outlined in FIGS. 12 to 16 inevitably increase the complexity of the device.
[0016]
[Means for Solving the Problems]
The method of bending the uppermost layer of the stacked coverglass blocks convexly downward, allowing air to enter from the side, and peeling off from the next layer of coverglass, ensures that the uppermost layer of coverglass can be removed and obtained. It is valid. In addition, the cover glass is brought into contact with the slide glass in a state where the cover glass is elastically deformed convexly toward the slide glass, and the cover glass is formed on the slide glass while recovering the deformation and eliminating the air interposed between the two glasses to the side. The overlapping method ensures the air exclusion action.
[0017]
In view of the above, the present invention employs a method in which a cover glass is curved, taken out from a cover glass block, and superimposed on a slide glass in a curved state, and is designed so that this can be performed with a simple mechanism.
[0018]
That is, the method of the present invention uses an apparatus in which a suction pad is attached to an arm that is rotatable about a horizontal axis, and when the top cover glass is removed from the stacked cover glass blocks, the top cover is removed. Attach one end far from the center of rotation of the glass arm with a pad and rotate the arm upward, and press the free end of the other end against the next layer of cover glass to make the uppermost cover glass elastic downwardly convex. Curve, let air in between the top and next layers of cover glass, peel off both cover glasses and, when overlaying the cover glass on the slide glass, hang the free end down with the suction pad inclined. The free end of the cover glass is first brought into contact with the slide glass, then the arm is rotated in the opposite direction to elastically curve the cover glass downwardly convex, the suction end is brought close to the slide glass, While eliminating those overlapping the cover glass to the glass slide.
[0019]
[Action]
When the uppermost cover glass is taken out from the cover glass block as described above, the uppermost cover glass can lift the suction end by the rotation of the arm, but the free end is restrained by the next layer cover glass, The coverglasses are elastically curved downward and air enters, the coverglasses are peeled off, and the uppermost coverglass can be easily removed.
[0020]
When attaching this cover glass to a slide glass, one end of the cover glass is sucked by a suction pad attached to an arm that is rotatable about a horizontal axis, and the cover glass is suspended with its free end down. The free end of the cover glass that has been rotated is brought into contact with the cover glass by rotating the arm, and the cover glass is brought close to the slide glass while being elastically curved convexly toward the slide glass. The air is pushed out to the side adsorbed on the pad , and the cover glass can be overlaid on the slide glass without leaving the air.
[0021]
Various means are conceivable for relatively moving the cover glass case, the slide glass, and the suction pad in order to operate as described above, but all of them can be easily configured by an ordinary mechanism, and the cover glass block is removed from the cover glass block. The glass can be taken out one by one, and the taken out cover glass can be reliably stacked on the slide glass without leaving air bubbles.
[0022]
【Example】
FIG. 1 is a schematic side view showing an outline of an apparatus for carrying out a method for attaching a cover glass to a microscope specimen according to the present invention, FIG. 2 is a schematic side view showing a state in which one of the uppermost layers is removed from a cover glass block, and FIG. 5 to 5 are schematic side views showing a situation in which the cover glass is mounted on the slide glass in a superposed manner, FIG. 6 is a side view showing another example of the structure of the arm, FIG. 7 is a plan view thereof, and FIG. FIGS. 6A to 6C are side views schematically illustrating another configuration example in which the slide glass is superimposed on a slide glass immediately below a glass block, and FIGS. The same parts as those in the above-described conventional example are denoted by the same reference numerals, and the description thereof is omitted.
[0023]
In FIG. 1, the suction pad 3 supported by the arm 16 is located above one end of the cover glass of the case 5 in which the blocks of the cover glasses 1 and 1 placed on the support plate 15 are placed. A support rod 17 with the pad 3 attached to the lower end thereof is fitted to the arm 16 in a vertically movable manner, and a flexible pipe 18 for connecting the inside of the suction pad to a vacuum pump is connected to the upper end. Between them, a compression spring 19 for buffering is interposed. The arm 16 is driven by a motor 23 in a clockwise direction and a counterclockwise direction about a shaft 22 that is horizontal to a sleeve 21 that can move up and down along a column 20 and is rotatable. The sleeve 21 moves up and down by engagement of a gear (not shown) with a rack 20 a formed on the column 20 by rotation of the motor 24. The column 20 is rotatably supported on a table 25, and the slide glass 10 on which the sample 12 is adhered and stained is placed on the table 25, and the mounting agent 13 is dropped on the slide glass 10 by a nozzle 26.
[0024]
In order to take out the uppermost cover glass 1a of the cover glass block placed in the case 5 placed on the support plate 15, first, the sleeve 21 is lowered along the column 20, and the plane formed by the lower edge of the pad 3 is made horizontal. The cover glass is brought into contact with the left end of the top cover glass 1a, and the cover glass is sucked. Next, in this state, the motor 23 is rotated to rotate the arm 16 slightly clockwise. As a result, the plane formed by the lower edge of the pad is inclined upward and downward to the right. When the sleeve 21 is slightly lowered (or the support plate 15 is slightly raised) in accordance with this, the uppermost cover glass 1a is moved to the position shown in FIG. Then, the right end is abutted against the cover glass 1c of the next layer as shown in FIG. As a result, air enters between the top layer and the next layer of cover glass, and both cover glasses are easily separated. Then, by raising the sleeve 21 (or lowering the support plate 15) and rotating the column 20 to remove the pad 3 from the position above the case 5, the uppermost cover glass 1a is tilted while being adsorbed by the pad 3. And suspended in the air.
[0025]
Next, in order to overlap the thus-suspended cover glass 1a on the slide glass 10, the cover glass 1a is positioned above the slide glass 10 on which the sample 12 is adhered and the encapsulant 13 is dropped. The sleeve 21 is lowered toward the slide glass, and first, the free end of the cover glass 1a, which is inclined and adsorbed to the pad 3, is brought into contact with the right end of the slide glass as shown in FIG. Subsequently, when the sleeve 21 is further lowered a little, the cover glass 1a curves downwardly convex as shown in FIG. When the arm 16 is rotated counterclockwise in this state, and finally the suction by the pad 3 is released, the cover glass 1a overlaps the slide glass 10 while gradually pushing the air between the slide glass 10 to the left and the cover. Can be mounted on glass.
[0026]
When the cover glass is removed one after another from the upper layer, the thickness of the cover glass block becomes small. Therefore, this operation is performed by raising and lowering the sleeve 21 or the support plate 15 to return to the initial state.
[0027]
The state in which the cover glass is curved when the cover glass is removed from the cover glass block changes depending on the position of the rotation center of the arm 16. For example, as shown in FIG. 2, when the shaft 22 serving as the center of rotation is located between the free end of the cover glass 1 a and the pad 3, the left end and the right end of the cover glass 1 a are both clockwise by the clockwise rotation of the arm 16. When the cover glass is rotated in the direction, the right end of the cover glass is pressed against the cover glass of the next layer, so that the cover glass curves downward. Therefore, it is not necessary to move the sleeve 21 or the support plate 15 to bend.
[0028]
As shown in FIG. 5, when the rotation center axis 22 of the arm 16 is displaced rightward from the cover glass, the free end (right end) of the uppermost cover glass 1a is also rotated clockwise by the clockwise rotation of the arm 16. At this time, the sleeve 21 or the support plate 15 is moved up and down because the uppermost cover glass is difficult to bend downwardly when trying to rotate.
[0029]
6 and 7 schematically show the configuration of the arm 16 and the like for positioning the rotation center of the arm 16 between the suction end and the free end of the glass as described above. The base 16 a of the arm 16 is formed as a bifurcated portion sandwiching the case 5, and the bifurcated bracket 21 a is projected from the sleeve 21 so that the base 16 a of the arm is pivotally connected to the side of the case 5 with a shaft 22 a. This shaft 22a becomes the rotation center of the arm 16. The center position is selected so that the curvature of the cover glass is not excessive. If the base 16a is of a cantilever type, the base 16a and the bracket 21a do not have to be bifurcated.
[0030]
The configuration shown in FIG. 1 is an example in which the column 20 is rotated so that the cover glass is overlapped on the slide glass 10 immediately below the case while avoiding collision between the sucked cover glass and the case 5, the support plate 15, and the like. 8 (a) to 8 (c) schematically show a configuration example in which this is performed without rotating the column 20.
[0031]
The operation in this configuration will be described below. First, as shown in FIG. 8A, if the end of the uppermost cover glass 1a is sucked by the suction pad 3, the arm 16 is rotated clockwise. 8B so as to avoid collision with the case 5 and the like. In this state, the sleeve 21 is lowered, and the cover glass 1a is lowered by passing beside the case 5 and the support plate 15. When the sleeve 21 is sufficiently lowered, the arm 16 is rotated counterclockwise as shown in FIG. 8C, and the cover glass 1a is overlaid on the slide glass 10. With this configuration, the device can be configured without rotating the support column 20.
[0032]
As described above, according to the method of the present invention, by rotating the arm 16 supporting the suction pad 3, the end face of the cover glass 1 that sucks the end portion far from the rotation center of the arm 16 is tilted, and the cover glass is inclined. The free end of the glass is supported by the next layer of cover glass or slide glass, the cover glass is elastically curved downwardly convex, and air enters between the next layer of cover glass and the uppermost layer of cover glass. In addition, since the cover glass is attached without discharging air between the slide glass and air bubbles between the slide glass and the slide glass, the arm 16 to which the suction pad is attached, the cover glass case 5, and the slide glass are attached. The purpose can be achieved by variously changing the positional relationship and the exercise system of the table 25 on which the table is placed.
[0033]
For example, in FIG. 1, after adsorbing the uppermost cover glass 1a, the support plate 15 on which the case 5 is placed is retracted to the left, the sleeve 21 is lowered, and the cover glass is overlaid on the slide glass placed on the table 25. The support plate 15 is immobilized, and if the pad 3 sucks the uppermost cover glass, the column 20 is rotated, and the arm 16 is lowered to avoid the case 5 so that the cover glass is overlaid on the slide glass. The arm 16 and the case 5 are rotated while the base 20 and the base 25 are coupled to avoid collision between the arm 16 and the case 5, the case 5 and the slide glass 10 are separately moved toward and away from the arm 16 that rotates vertically at a fixed position, or As described above, the method of the present invention can be implemented by combining mechanisms such as rotating the arm to avoid collision with the case 5 and the support plate 15.
[0034]
【The invention's effect】
According to the cover glass attaching method of the present invention, the cover glass is bent, the air is introduced between the cover glass of the next layer, and the cover glass is taken out one by one from the cover glass block. Since the operation of superimposing on the slide glass is performed by rotating the arm that supports the suction pad, the device for performing this operation is simple, and the accompanying devices can be easily configured, so that a good microscope specimen can be prepared. Can be performed efficiently.
