ミクロトーム用組織包埋カセット載置台として、従来から、例えば実開昭５８ −２６４９号公報記載のもの等が知られている。 As a tissue embedding cassette mounting table for a microtome, for example, the one described in Japanese Utility Model Laid-Open No. 58-2649 has been conventionally known.
【０００３】 しかしながら、従来のこの種の組織包埋カセット載置台は、大きさの異なる別 の種類の組織包埋カセットを載置するためには、シムを介在させたり、微調節ネ ジを操作したりして、その度に再調節が必要で有り、操作性があまり良くないと いう欠点があった。However, in the conventional tissue embedding cassette mounting table of this type, in order to mount another type of tissue embedding cassette having a different size, a shim is interposed or a fine adjustment screw is operated. However, it had to be readjusted each time, and the operability was not very good.

図示した実施例において、１はミクロトーム（図示せず）に対して固定される べき底板で、該底板の一端には側板２が立設され、同じく該底板の他端には受け 側板３が対向して立設されている。４は該側板と受け側板との間に該底板と平行 をなすように掛け渡された４本の平行な案内棒で、該案内棒には操作駒５が摺動 自在に嵌合し、該操作駒はそれらに沿って該底板上を平行移動する。６は該操作 駒に先行してその受け側板側に配置された押え駒で、該押え駒はそれと一体の鍔 付き突出棒６ａにより該操作駒に対する最大突出量が規制され、該操作駒との間 に介在する圧縮バネ６ｂにより該操作駒から最大突出量突出した最大先行位置に 付勢されている。７は該案内棒と平行にそれらより高くならない位置に配置され た操作扞で、該操作扞の一端７ｂは前記受け側板３近傍で上下方向に揺動自在に 担持され、他端７ａは前記側板２の上下方向の長孔２ａを貫通して突出し、中間 部を該底板との間に介在する板バネ８により上方向に付勢されている。また、該 操作扞はその上面にラチェットホイールを平面上に展開した形状のラチェット列 部７ｃを具え、一方、前記操作駒５には対応する位置に該ラチェット列部に係合 するラチェット爪５ａが固定して設けられている。したがって、該操作扞の他端 部７ａが板バネの作用で長孔２ａの上端部に当接する上限位置に付勢されている ときには、該ラチェット列部とラチェット爪とで構成されるラチェット機構の作 用により、該操作駒が受け側板に接近する前進方向にのみ摺動可能で、後退でき ない構成となっている。 In the illustrated embodiment, 1 is a bottom plate to be fixed to a microtome (not shown), a side plate 2 is erected at one end of the bottom plate, and a receiving side plate 3 is also opposed to the other end of the bottom plate. And is erected. Reference numeral 4 denotes four parallel guide rods which are laid between the side plate and the receiving side plate so as to be parallel to the bottom plate, and the operation piece 5 is slidably fitted to the guide rods. The operation piece moves in parallel on the bottom plate along them. Reference numeral 6 denotes a pressing piece arranged on the receiving side plate side prior to the operating piece, and the pressing piece has a maximum protruding amount with respect to the operating piece restricted by a protruding rod 6a with a collar integrated with the operating piece. A compression spring 6b interposed between the operation pieces urges the operation piece to a maximum leading position which is a maximum amount of protrusion. Reference numeral 7 denotes an operating bar arranged in a position parallel to the guide rod and not higher than them, one end 7b of the operating bar is movably supported in the vertical direction in the vicinity of the receiving side plate 3, and the other end 7a thereof is the side plate. 2 is projected through the vertically elongated hole 2a, and an intermediate portion is urged upward by a leaf spring 8 interposed between the middle portion and the bottom plate. Further, the operation bar has a ratchet row portion 7c having a shape in which a ratchet wheel is developed on a flat surface on the upper surface thereof, while the operation piece 5 has ratchet pawls 5a engaging with the ratchet row portion at a corresponding position. It is fixedly provided. Therefore, when the other end 7a of the operating bar is biased to the upper limit position where it abuts the upper end of the elongated hole 2a by the action of the leaf spring, the ratchet mechanism composed of the ratchet row part and the ratchet pawl is operated. Due to the operation, the operation piece can slide only in the forward direction in which the operation piece approaches the receiving side plate, and cannot move backward.

すなわち、４本の平行な案内棒４で構成されるすのこ状の置き台における、受 け側板３とこれに対向する十分に後退された位置にある押え駒６との間に、組織 包埋カセット（図示せず）を載置し、操作駒５を受け側板３に向けて手で前進さ せると、それらの間隔が狭まり、一対の挟持手段を構成する該受け側板と押え駒 とで該組織包埋カセットを挟み込む。ここで更に、圧縮バネ６ｂの力に抗して操 作駒５を前進させると該圧縮バネが圧縮され、その反発力で該組織包埋カセット が確実に挟持される。このとき該操作駒は前記ラチェット機構の作用により後退 を阻止されている。該ラチェット機構の作用を解除するには、操作扞７の端部７ ａを板バネ８の力に抗して押し下げればよい。これにより、前記ラチェット列部 ７ｃとラチェット爪５ａとの係合関係が解除され、操作駒６は圧縮バネ６ｂの復 元力により後退し、組織包埋カセットは挟持手段による固定を解除される。 That is, a tissue-embedding cassette is formed between the receiving side plate 3 and the pressing piece 6 in a sufficiently retracted position facing the receiving side plate 3 in a sludge-shaped stand composed of four parallel guide rods 4. When an operation piece 5 (not shown) is placed and manually advanced to the receiving side plate 3 toward the receiving side plate 3, the space between them is narrowed, and the tissue is formed by the receiving side plate and the pressing piece forming a pair of holding means. Insert the embedding cassette. Here, when the operating piece 5 is further advanced against the force of the compression spring 6b, the compression spring is compressed, and the repulsive force reliably holds the tissue-embedding cassette. At this time, the operation piece is prevented from retreating by the action of the ratchet mechanism. In order to cancel the action of the ratchet mechanism, the end portion 7a of the operating bar 7 may be pushed down against the force of the leaf spring 8. As a result, the engagement relationship between the ratchet row portion 7c and the ratchet claw 5a is released, the operation piece 6 is retracted by the restoring force of the compression spring 6b, and the tissue-embedding cassette is released from the clamping means.
【０００８】 本考案は上記した実施例に限られるものではなく、ラチェット爪とラチェット 列部とからなる直線状のラチェット機構は操作扞の長手方向に沿ったその上下左 右何れの面にも設けることができる。The present invention is not limited to the above-described embodiment, and a linear ratchet mechanism including a ratchet claw and a ratchet row portion is provided on any of the upper, lower, left, and right surfaces of the operating bar along the longitudinal direction thereof. be able to.

本考案は以上のように構成されているから、大きさの異なる複数の種類の組織 包埋カセットを使用する場合であっても、操作駒を使用するカセットの大きさに 合わせて後退させておき、次に、一挙動で押し込むという同じ操作を行えばよく 、シムを介在させたり、微調節ネジを操作したりするという従来技術に較べて操 作性の優れたミクロトーム用組織包埋カセット載置台を提供することができる。 Since the present invention is configured as described above, even when a plurality of types of tissue-embedding cassettes of different sizes are used, the operation piece should be retracted according to the size of the cassette to be used. Then, the same operation of pushing in with a single action may be performed, and the tissue embedding cassette mounting table for the microtome, which has better operability than the conventional technology of interposing a shim or operating a fine adjustment screw, Can be provided.
