Description

本発明は、病理組織等の生物標本の薄片が貼り付けられた顕微鏡観察用のプレパラートを収納できるプレパラート収納ケースに係り、特に、収納ケース内の収容部を容易に取り外すことが出来るとともに、収容部が外枠部から完全に引き出される前に、使用者に対し警報を発することにより、収容部の落下事故を防止することができる、安全性が高く且つ使いやすいプレパラート収納ケースに関する。 The present invention relates to a preparation storage case that can store a preparation for microscopic observation to which a thin piece of a biological specimen such as a pathological tissue is attached, and in particular, the storage section in the storage case can be easily removed and the storage section The present invention relates to a safe and easy-to-use preparation storage case that can prevent a drop accident of the storage portion by issuing an alarm to the user before the cover is completely pulled out from the outer frame portion.

生物組織、例えば病理組織の検査は、患者の患部より切除した組織を通常、カセットと称される多数の透孔を有する容器内に入れ、ホルマリン液等により薬液処理した後、包埋トレイと称される容器内に薬液処理した組織を入れた後、包埋トレイの上にカセットを載せ、カセットの上方から溶融パラフィンを包埋トレイ内に流下させ、カセット底部の外側に、組織を包埋したパラフィンブロックが付着した所謂包埋ブロックとされる。この包埋ブロックは、ミクロトームと称される装置の上に組織を包埋するパラフィンブロックを上にして固定された後、薄切りし、切り出した組織片をスライドガラスに載せ、染色を施してカバーガラスを被せ、得られたプレパラートは顕微鏡で観察される。 Biological tissues such as pathological tissues are usually examined by placing the tissue excised from the affected area of a patient in a container having a large number of through holes called cassettes, treating with chemicals with formalin solution, etc., and then calling it an embedding tray. After placing the chemical-treated tissue in the container to be placed, the cassette was placed on the embedding tray, the molten paraffin was allowed to flow into the embedding tray from above the cassette, and the tissue was embedded outside the bottom of the cassette It is a so-called embedding block to which a paraffin block is attached. This embedding block is fixed on a device called a microtome with a paraffin block that embeds the tissue facing up, then sliced, the cut tissue piece is placed on a slide glass, stained, and covered with a cover glass. The prepared preparation is observed with a microscope.

上記のようにして作成したプレパラートは、再検査の際などに利用できるように、プレパラートケースに収納して保管される。そして、病理組織を再度、観察したい場合、プレパラートケースから所定のプレパラートを取り出して顕微鏡で観察される。 The prepared slide is stored in a prepared case so that it can be used for re-examination. When it is desired to observe the pathological tissue again, a predetermined preparation is taken out from the preparation case and observed with a microscope.

包埋ブロックやスライドガラス（プレパラート）などの試料を整理するための整理ケースとして、多数の包埋ブロックを平面視して縦横に区画して収容する包埋ブロック収納部と、スライドガラスを収容するスライドガラス収納部と、を備え、包埋ブロック収納部による包埋ブロックの配列に、スライドガラス収納部によるスライドガラスの配列を対応させてある整理ケースが提案されている（特許文献１）。 As an organizing case for organizing samples such as embedding blocks and slide glasses (preparations), it contains an embedding block storage section that accommodates a large number of embedding blocks divided vertically and horizontally and accommodates slide glasses. An arrangement case has been proposed in which a slide glass storage unit is provided, and the arrangement of the slide glass by the slide glass storage unit corresponds to the arrangement of the embedded blocks by the embedded block storage unit (Patent Document 1).

しかしながら、上記特許文献１のような整理ケースでは、目的とする包埋ブロックやスライドガラスを取り出しやすいものの、包埋ブロックやスライドガラスを寝かせた状態で収納するため、包埋ブロック一個当り、又は、スライドガラス一枚当りの必要スペースはかなり大きくなってしまう。しかも、使用済み包埋ブロックや使用済みスライドガラスは大量に発生するが、これらの再検査の頻度はそれほど高くないので、使用頻度が低い試料に大きな保存スペースが必要になるという不都合が生じる。 However, in the organizing case like the above-mentioned Patent Document 1, although it is easy to take out the target embedding block or slide glass, in order to store the embedding block or slide glass in a laid state, per embedding block, or The required space per glass slide becomes quite large. In addition, although a large amount of used embedding blocks and used slide glasses are generated, the frequency of these reexaminations is not so high, resulting in the disadvantage that a large storage space is required for samples that are used infrequently.

一方、外枠部内に収納された収容部を引き出し式に引き出すことができ、該収容部の底部付近に長手方向にコイル状のスプリングを張設し、このスプリングにスライドガラスを挟み込む標本マルチラックが販売されている（非特許文献１）。
このようなラックはスライドガラスを垂直に立てて収納するので、小さなスペースに大量のプレパラートを収納することができる。また、必要に応じ、引き出しを外枠部から完全に取り外した状態で持ち運ぶことができるので便利である。
この種の標本マルチラックでは、引き出しの前面に取っ手が設けられ、収容部を引き出す際はこの取っ手に指を引っ掛けて引っ張るように構成されており、該収容部を取り外す際には収容部の大半が引き出され、且つ後端がまだ外枠部内に残っている状態で手を収容部の下に添えて持ち上げるようにされている。
しかしながら、このようなラックでは、取っ手をどこまで引っ張れば収容部の後端が外枠部から外れるのか見当を付け難く、誤って引っ張りすぎて収容部の下に手を添える前に収容部の後端が外枠部から外れてしまい、収容部を落下させて貴重な資料を台無しにする恐れがある。
また、プレパラートはガラス製であり、各ラック内には大量のプレパラートが収納され重量も大きいため、これが作業者の足の上にでも落下すれば大怪我する場合もある。 On the other hand, the storage unit accommodated in the outer frame part can be pulled out in a pull-out manner, and a sample multi-rack is provided in which a coiled spring is stretched in the longitudinal direction near the bottom of the storage unit, and a slide glass is sandwiched between the springs. It is sold (Non-Patent Document 1).
Since such a rack stores the slide glass vertically, it can store a large amount of preparation in a small space. Further, it is convenient because it can be carried with the drawer completely removed from the outer frame portion as required.
In this type of specimen multi-rack, a handle is provided on the front surface of the drawer, and when pulling out the storage portion, the handle is configured to be pulled by pulling a finger on the handle. Is pulled out, and the hand is attached to the bottom of the housing portion and lifted with the rear end still remaining in the outer frame portion.
However, in such a rack, it is difficult to determine how far the rear end of the housing part comes off from the outer frame part by pulling the handle, and the rear end of the housing part is accidentally pulled too much before putting the hand under the housing part. May fall out of the outer frame, dropping the storage section and ruining valuable materials.
Moreover, since the preparation is made of glass and a large amount of preparation is stored in each rack and its weight is large, if it falls on the operator's foot, it may be seriously injured.

本発明によるプレパラート収納ケースは、収容部の底板下面後端には後端指示部が設けられ、外枠部の底板上面前縁付近には前縁指示部が設けられ、収容部を前方に引き出して後端指示部が前縁指示部に当接したときに、収容部が持ち上がり、又は沈み込むよう構成されているので、収容部が持ち上がり、又は沈み込んだ感触が取っ手を持つ使用者の手指に伝わり、この感触が警報として作用して、使用者はそれ以上引っ張ると収容部が落下する危険があることを知り、収容部が落下しないように収容部の下に手を添えることができる。その結果、誤って引っ張りすぎて収容部を落下させる事故が未然に防がれ、安全性が高まる。 In the preparation storage case according to the present invention, a rear end indicating portion is provided at the rear end of the bottom surface of the bottom plate of the receiving portion, and a front edge indicating portion is provided in the vicinity of the front edge of the top surface of the bottom plate of the outer frame portion. When the rear end indicating portion comes into contact with the front edge indicating portion, the storage portion is configured to lift or sink, so that the user's finger having a handle that the storage portion is lifted or sinks is used. This feeling acts as an alarm, and the user knows that there is a danger that the container will fall if pulled further, and can put his hand under the container so that the container will not fall. As a result, an accident that causes the container to fall due to excessive pulling is prevented in advance, and safety is improved.

収容部の後端と後端指示部の間、及び／又は、外枠部の前縁と前縁指示部の間に間隙部を設けることにより、収容部が持ち上がり、又は沈み込んで警告を発した後、収容部が間隙部を引き出される間の時間的に猶予が与えられ、収容部の下に手を添える等の適切な落下防止手段をとることができる。 By providing a gap between the rear end and the rear end indicating portion of the receiving portion and / or between the front edge and the front edge indicating portion of the outer frame portion, the receiving portion rises or sinks and a warning is issued. After that, a grace period is given while the accommodating portion is pulled out of the gap portion, and appropriate fall prevention means such as putting a hand under the accommodating portion can be taken.

後端指示部として収容部の底板下面に突起を垂設するとともに、前縁指示部として外枠部の底板上面から突起を立設し、後端指示部と前縁指示部の突出高さの和を収容部の底板と外枠部の底板の間隔よりも大きくすれば、収容部を引き出す際に収容部の後端が外枠部の前縁に近づいて、後端指示部が前縁指示部に当接し、この状態から更に収容部を引き出せば後端指示部が前縁指示部を乗り越え、その分収容部が持ち上がる。この収容部が持ち上がった感触は取っ手を引っ張る使用者の指に伝わるので、この感触が警報になって収容部の後端が外枠部の前縁に近づいた事を知ることができ、引っ張るのをやめて収容部の下に手を添える等の落下防止措置を取ることができる。 Protrusions are erected on the bottom plate bottom surface of the housing portion as the rear end indicating portion, and protrusions are erected from the upper surface of the bottom plate of the outer frame portion as the front edge indicating portion, If the sum is made larger than the distance between the bottom plate of the housing portion and the bottom plate of the outer frame portion, the rear end of the housing portion approaches the front edge of the outer frame portion when the housing portion is pulled out, and the rear end indicating portion indicates the front edge If the housing portion is further pulled out from this state, the rear end indicating portion gets over the front edge indicating portion, and the accommodating portion is lifted accordingly. The feeling that the container is lifted is transmitted to the finger of the user who pulls the handle, so that this feels an alarm and it can be known that the rear edge of the container has approached the front edge of the outer frame. It is possible to take a fall prevention measure such as stopping and putting a hand under the housing.

後端指示部を収容部の底板下面から垂設される突起とし、前縁指示部を外枠部の底板上面に穿設される窪みとし、後端指示部が収容部の底板と外枠部の底板の間隔保持用突起を兼ねるようにすれば、収容部を引き出す際、後端指示部が前縁指示部に近づく前は後端指示部で収容部全体が支えられ、収容部が外枠部から抜け落ちそうになると、後端指示部の突起がが前縁指示部の窪みに落ち込み、収容部が沈み込む。この収容部が沈み込む感触は取っ手を引っ張る使用者の指に伝わるので、この感触が警報になって収容部の後端が外枠部の前縁に近づいた事を知ることができる。
また、後端指示部が収容部の底板下面に穿設される窪みであるとともに、前縁指示部が外枠部の底板上面から垂設される突起であり、前縁指示部の突出高さが収容部の底板と外枠部の底板の間隔に略等しい場合も、同様である。 The rear end indicating portion is a protrusion that is suspended from the bottom surface of the bottom plate of the housing portion, the front edge indicating portion is a recess that is formed in the top surface of the bottom plate of the outer frame portion, and the rear end indicating portion is the bottom plate and the outer frame portion of the housing portion. If the housing is pulled out, the entire housing is supported by the rear end indicating unit before the rear end indicating unit approaches the front edge indicating unit. When it is about to fall out from the part, the protrusion of the rear end indicating part falls into the recess of the front edge indicating part, and the accommodating part sinks. Since the feeling that the accommodating portion sinks is transmitted to the finger of the user who pulls the handle, this feeling becomes an alarm and it can be known that the rear end of the accommodating portion has approached the front edge of the outer frame portion.
The rear end indicating portion is a recess formed in the bottom surface of the bottom plate of the housing portion, and the front edge indicating portion is a protrusion that is suspended from the top surface of the bottom plate of the outer frame portion. The same applies to the case where is substantially equal to the distance between the bottom plate of the housing portion and the bottom plate of the outer frame portion.

後端指示部と前縁指示部をそれぞれ２組設け、第２の後端指示部を収容部の後端付近に設け、第２の前縁指示部を外枠部の前縁に設ければ、収容部を斜め上方に引っ張った場合、及び斜め下方に引っ張った場合にも支障なく警報を発することができ、その結果、水平方向、斜め上方、斜め下方のいずれの方向に引っ張った場合でも収容部の落下事故を防止することができ、安全性が一層高められる。 If two sets of the rear end instruction part and the front edge instruction part are provided, the second rear end instruction part is provided in the vicinity of the rear end of the housing part, and the second front edge instruction part is provided at the front edge of the outer frame part. Even when the container is pulled obliquely upward and obliquely downward, an alarm can be issued without any trouble, and as a result, it can be accommodated when pulled in any of the horizontal, diagonally upward, and diagonally downward directions. This can prevent accidents of falling parts, further improving safety.

Each of the accommodating portions 4 is provided with individual pulling direction restricting means so that the accommodating portion 4 can be pulled out in the correct direction (in this specification, the directions such as front and rear, left and right, up and down are the accommodating portions 4). The direction of pulling out is the standard).
In the embodiment shown in FIG. 1 to FIG. 4, the two rails 2 a provided on the upper surface of the bottom plate of the outer frame portion 2 and the both edges of the lower surface of the bottom plate of the housing portion 4 are provided as the drawing direction restricting means. Guide ribs 4b are used to prevent sideways slipping of the housing portion 4 so that the housing portion 4 can be reliably inserted and removed in the front-rear direction.

本発明においては、収容部４の底板下面後端に設けられた後端指示部５及び外枠部２の底板上面前縁付近に設けられた前縁指示部３を用いて、収容部４を引き出す際、外枠部２から完全に抜け落ちる前に収容部４が持ち上がり、又は沈み込むようにされ、その感触が使用者の指に伝わって警報として働き、収容部４が抜け落ちる前に収容部４の引き出しを止め、或いは収容部４の下に手を添えることができるようになっている。 In the present invention, the housing portion 4 is used by using the rear edge indicating portion 5 provided at the rear end of the bottom surface of the bottom plate of the housing portion 4 and the front edge indicating portion 3 provided near the front edge of the top surface of the bottom plate of the outer frame portion 2. When pulling out, the container 4 is lifted or submerged before it completely falls out of the outer frame part 2, and the touch is transmitted to the user's finger to act as an alarm, and before the container 4 falls off, the container 4 Can be stopped, or a hand can be put under the housing 4.

具体的な構成としては、例えば図２乃至図４に示すように、後端指示部５を収容部４の底板下面後端から垂設される突起とするとともに、前縁指示部３を外枠部２の底板上面前縁付近から立設される突起とする。例えば、後端指示部５の突起の突出高さＨ１（例えば２ｍｍ）と前縁指示部３の突起の突出高さＨ２（例えば３ｍｍ）の和を収容部４の底板と外枠部２の底板の間隔Ｈ３（例えば４ｍｍ）よりも大きくする（上記の例では２＋３＝５ｍｍ）構成が例示できる。なお、図２乃至図４に示した例では、後端指示部５及び前縁指示部３として、第１のものと第２のものがそれぞれ設けられているが、以下の説明は主に第１のものに基づいて行っており、第２については後述する。
このようにすれば、図５（ａ）に示したように、後端指示部５と前縁指示部３が当接する前は収容部４をスムースに引き出すことができるが、図５（ｂ）に示したように、後端指示部５と前縁指示部３が当接すれば、後端指示部５が前縁指示部３を乗り越えるので収容部４は一定高さだけ持ち上がり（上記の例ではＨ１＋Ｈ２−Ｈ３＝２＋３−４＝１ｍｍ持ち上がる）、この感触が使用者の指に伝わるので、これが警報となり、使用者はこれ以上収容部４を引っ張ると落下の危険があることを知る。 As a specific configuration, for example, as shown in FIGS. 2 to 4, the rear end instructing portion 5 is a protrusion suspended from the rear end of the bottom surface of the bottom plate of the housing portion 4, and the front edge instructing portion 3 is an outer frame. A protrusion is erected from the vicinity of the front edge of the upper surface of the bottom plate of the portion 2. For example, the sum of the protrusion height H1 (for example, 2 mm) of the protrusion of the rear end indicating portion 5 and the protrusion height H2 (for example, 3 mm) of the protrusion of the front edge indicating portion 3 is the bottom plate of the housing portion 4 and the bottom plate of the outer frame portion 2. The distance H3 (for example, 4 mm) is larger (in the above example, 2 + 3 = 5 mm). In the examples shown in FIGS. 2 to 4, the first and second rear end indicating portions 5 and the leading edge indicating portion 3 are provided, respectively. The second is described later.
In this way, as shown in FIG. 5A, the accommodating portion 4 can be smoothly pulled out before the rear end indicating portion 5 and the front edge indicating portion 3 come into contact with each other, but FIG. As shown in FIG. 4, when the rear end indicating portion 5 and the leading edge indicating portion 3 come into contact with each other, the rear end indicating portion 5 gets over the front edge indicating portion 3, so that the accommodating portion 4 is lifted by a certain height (in the above example, H1 + H2−H3 = 2 + 3−4 = 1 mm), and this feeling is transmitted to the user's finger. This is an alarm, and the user knows that there is a risk of dropping if the container 4 is pulled further.

また、収容部４の後端と後端指示部５の間、及び／又は外枠部２の前縁と前縁指示部３の間には間隙部６が設けられている（図５では外枠部２の前縁と前縁指示部３（第１前縁指示部３ａ）の間、及び収容部４の後端と第２後端指示部５ｂの間）ので、収容部４が持ち上がり、又は沈み込んですぐに収容部４が外枠部２から脱落するのではなく、時間的な猶予が与えられ、この間に収容部４の下に手を添える等、必要な措置を取ることができる。 Further, a gap 6 is provided between the rear end of the housing portion 4 and the rear end indicating portion 5 and / or between the front edge of the outer frame portion 2 and the front edge indicating portion 3 (in FIG. Between the front edge of the frame portion 2 and the front edge indicating portion 3 (first front edge indicating portion 3a) and between the rear end of the receiving portion 4 and the second rear end indicating portion 5b), the receiving portion 4 is lifted, Alternatively, the storage unit 4 does not fall off the outer frame unit 2 immediately after sinking, but a grace period is given, and a necessary measure can be taken such as putting a hand under the storage unit 4 during this period. .

なお、図２乃至図４に示した例では、収容部４の底板と外枠部２の底板の間隔Ｈ３は、当該間隔Ｈ３と同じ高さのガイドリブ４ｂにより保持されているが、この方法に限定されず、例えばレール２ａを当該間隔Ｈ３と同じ高さにしてもよいし、その他、間隔保持用の突起等を別途設けてもよい。 In the example shown in FIGS. 2 to 4, the distance H3 between the bottom plate of the housing part 4 and the bottom plate of the outer frame part 2 is held by the guide rib 4b having the same height as the distance H3. For example, the rail 2a may have the same height as the interval H3, and other protrusions for maintaining the interval may be separately provided.

後端指示部５及び前縁指示部３としての突起はそれぞれ一個づつ設ければ十分であるが、より強い警報を発するために、後端指示部５、前縁指示部３のいずれか、又は両方を２以上連設することもでき、図２乃至図４に示した例では前縁指示部３が突起を３つ連設した形状とされている。この場合、使用者には、単に収容部４が持ち上がり、または沈み込む感触だけでなく、ガタガタと振動するような感触が伝わり、より強い警報として感じられる。このような効果は、図６に示すように、前縁指示部３を１つにして後端指示部５を３つ連設した形状としても得ることができる。 It is sufficient to provide one protrusion as each of the rear end instructing unit 5 and the front end instructing unit 3, but either one of the rear end instructing unit 5 or the front edge instructing unit 3 or Two or more of them can be connected in series, and in the example shown in FIGS. 2 to 4, the leading edge indicator 3 has a shape in which three protrusions are connected. In this case, the user feels not only a feeling that the accommodating portion 4 is lifted or sinks but also a feeling that vibrates rattlingly, and feels as a stronger alarm. As shown in FIG. 6, such an effect can also be obtained with a shape in which the front edge indicating portion 3 is one and the three rear end indicating portions 5 are continuously provided.

図２乃至図４に示した例において、後端指示部５及び前縁指示部３として使用される突起は双方とも収容部４の引き出し方向に対して横長とされているが、突起の形状についてはこれに限られず、例えば半球状の突起を設けてもよい。なお、後端指示部５が前縁指示部３を乗り越え易くするように、これらの突起における収容部の前後の面は斜面状としておくほうが好ましい。
また、上記の例では、収容部４を引き出す際には、後端指示部５及び前縁指示部３として使用される突起が互いに正面から衝突するように構成されているが、これに限らず、例えば図７に示したように、突起として斜め方向に長いものを設け、これらの突起が斜めに衝突するようにしてもよい。
或いは、図８に示したように、後端指示部５及び前縁指示部３を左右２列に設けるとともに、これらのいずれか一方又は両方を前後にずらして配置することにより、収容部４の引き出し時に後端指示部５及び前縁指示部３が当接するタイミングを左右でずらすようにしてもよい。
なお、後端指示部５及び前縁指示部３を斜めに設けたり、左右２列に設けて左右で後端指示部５及び前縁指示部３が当接するタイミングをずらすと、収容部４に横向きの応力が加わり、引き出し方向規制手段（図２乃至図４に示した例ではレール２ａ及びガイドリブ４ｂ）がスムースに滑らなくなるのでブレーキのように機能する。従って、例え勢いよく収容部４を引っ張ったとしても、外枠部２から外れる寸前にその勢いが削がれるので、該収容部４が不意に脱落する危険が減少する。 In the example shown in FIGS. 2 to 4, the projections used as the rear end indicating portion 5 and the leading edge indicating portion 3 are both horizontally long with respect to the pulling direction of the accommodating portion 4. Is not limited to this, and for example, a hemispherical protrusion may be provided. In addition, it is preferable that the front and rear surfaces of the housing portion of these protrusions be sloped so that the rear end instructing portion 5 can easily get over the front edge instructing portion 3.
Further, in the above example, when the housing portion 4 is pulled out, the projections used as the rear end indicating portion 5 and the front edge indicating portion 3 are configured to collide with each other from the front. For example, as shown in FIG. 7, long protrusions may be provided as the protrusions, and these protrusions may collide obliquely.
Alternatively, as shown in FIG. 8, the rear end indicator 5 and the front edge indicator 3 are provided in two rows on the left and right sides, and either or both of them are shifted in the front-rear direction, You may make it shift the timing which the rear-end instruction | indication part 5 and the front edge instruction | indication part 3 contact | abut at the time of pulling out right and left.
In addition, if the rear end instructing unit 5 and the front edge instructing unit 3 are provided obliquely, or provided in two rows on the left and right sides and the timing at which the rear end instructing unit 5 and the front edge instructing unit 3 abut on each side is shifted, Lateral stress is applied, and the pull-out direction restricting means (the rail 2a and the guide rib 4b in the example shown in FIGS. 2 to 4) does not slip smoothly and functions like a brake. Therefore, even if the accommodating portion 4 is pulled vigorously, the momentum is scraped just before it is detached from the outer frame portion 2, so that the risk of the accommodating portion 4 dropping off unexpectedly is reduced.

以上、後端指示部５及び前縁指示部３を双方とも突起とする構成について説明したが、後端指示部５、前縁指示部３のいずれか一方を窪みにしても同様の効果が得られる。
例えば、図９（ａ）に示すように、後端指示部５を収容部４の底板下面後端から垂設される突起とするとともに、前縁指示部３を外枠部の底板上面前縁付近に穿設される窪みとし、後端指示部５が収容部の底板と外枠部の底板の間隔保持用突起を兼ねるようにすれば、後端指示部５と前縁指示部３が当接する前は収容部４をスムースに引き出すことができるが、図９（ｂ）に示したように、後端指示部５と前縁指示部３が当接すれば、後端指示部５が前縁指示部３の中に落ちこみ、これにより収容部４が沈み込み、この感触が警報となって使用者の指に伝わるので、使用者はこれ以上収容部４を引っ張ると落下の危険があることを知る。 The configuration in which both the rear end instructing section 5 and the leading edge instructing section 3 are projections has been described above, but the same effect can be obtained even if either the rear end instructing section 5 or the front edge instructing section 3 is recessed. It is done.
For example, as shown in FIG. 9A, the rear end indicating portion 5 is a protrusion that is suspended from the rear end of the bottom surface of the bottom plate of the housing portion 4, and the front edge indicating portion 3 is the front edge of the top surface of the bottom plate of the outer frame portion. If the rear end instructing part 5 serves as a space holding projection for the bottom plate of the housing part and the bottom plate of the outer frame part, the rear end instructing part 5 and the front edge instructing part 3 are in contact with each other. Before the contact, the accommodating portion 4 can be pulled out smoothly. However, as shown in FIG. 9B, if the rear end indicating portion 5 and the front edge indicating portion 3 are in contact, the rear end indicating portion 5 is It falls into the instruction unit 3, so that the storage unit 4 sinks, and this touch becomes an alarm and is transmitted to the user's finger. Therefore, if the user pulls the storage unit 4 further, there is a risk of dropping. know.

また、図１０（ａ）に示すように、後端指示部５を収容部４の底板下面に穿設される窪みとするとともに、前縁指示部３を外枠部２の底板上面から立設される突起とし、前縁指示部３が収容部４の底板と外枠部２の底板の間隔保持用突起を兼ねるようにすれば、後端指示部５と前縁指示部３が当接する前は収容部４をスムースに引き出すことができるが、図１０（ｂ）に示したように、後端指示部５と前縁指示部３が当接すれば、後端指示部５の内部に前縁指示部３の先端が入り込み、これにより収容部４が沈み込み、この感触が警報となって使用者の指に伝わるので、使用者はこれ以上収容部４を引っ張ると落下の危険があることを知る。 Further, as shown in FIG. 10A, the rear end indicating portion 5 is a recess formed in the lower surface of the bottom plate of the housing portion 4 and the front edge indicating portion 3 is erected from the upper surface of the bottom plate of the outer frame portion 2. If the front edge indicating portion 3 serves as a space holding protrusion for the bottom plate of the housing portion 4 and the bottom plate of the outer frame portion 2 before the rear end indicating portion 5 and the front edge indicating portion 3 come into contact with each other, 10 can smoothly pull out the accommodating portion 4, but as shown in FIG. 10B, if the rear end indicating portion 5 and the front edge indicating portion 3 come into contact with each other, the front edge is placed inside the rear end indicating portion 5. Since the tip of the indicating unit 3 enters, the housing unit 4 sinks, and this feeling is transmitted to the user's finger as an alarm. Therefore, if the user pulls the housing unit 4 further, there is a risk of dropping. know.

なお、図９及び図１０に示すように、後端指示部５及び前縁指示部３のいずれか一方が間隔保持用突起を兼ねるようにし、他方を窪みとした場合でも、双方を突起とした場合と同様、後端指示部５及び前縁指示部３のいずれか一方又は両方を複数設けて、収容部４が振動するようにしてもよいし、後端指示部５及び前縁指示部３を斜めに設けたり、左右２列に設けて左右で後端指示部５及び前縁指示部３が当接するタイミングをずらすこともできる。 As shown in FIGS. 9 and 10, even if either one of the rear end indicating portion 5 and the front edge indicating portion 3 also serves as a spacing holding projection and the other is a recess, both are defined as projections. Similarly to the case, either one or both of the rear end instructing unit 5 and the front edge instructing unit 3 may be provided so that the housing unit 4 vibrates, or the rear end instructing unit 5 and the front edge instructing unit 3 Can be provided obliquely, or provided in two rows on the left and right sides, and the timing at which the rear end indicator 5 and the front edge indicator 3 abut on the left and right can be shifted.

以上、収容部４を引き出す際に、収容部４を水平方向に引っ張る例について説明したが、以下、収容部４を斜め上方、又は斜め下方に引っ張る例について説明する。
図１１（ａ）（ｂ）に示したように、後端指示部５を収容部４の後端に設けた場合、収容部４を斜め上方に引っ張っても後端指示部５は前縁指示部３に衝突して、この前縁指示部３を乗り越えるため、収容部４は持ち上がり、警報として作用する。
しかしながら、図１２（ａ）に示したように、収容部４を斜め下方に引っ張った場合、前縁指示部３と衝突する前に収容部４の後端が浮き上がり、そのまま収容部４を引っ張っても、図１２（ｂ）に示したように、後端指示部５が前縁指示部３の上を通過して、警報として作用しない危険性が生じる。
このように、収容部４を斜め下方に引っ張ることが予想される場合には、図１３（ａ）に示すように、外枠部２の前縁に前縁指示部３（第２前縁指示部３ｂ）を設けるとともに、間隙部６は収容部４の後端と後端指示部５（第２後端指示部５ｂ）の間に設けるようにする。但し、この場合、収容部４を斜め上方に引っ張ったときに、前縁指示部３と衝突する前に収容部４の後端が浮き上がり、後端指示部５が前縁指示部３の上を通過して、警報として作用しない危険性が生じる。
従って、収容部４を斜め上方及び斜め下方のいずれにも引っ張る可能性がある場合には、例えば図４（ａ）（ｂ）に示したように、収容部４の後端に設けられた第１後端指示部５ａと、外枠部２の前縁付近に間隙部６を介して設けられた第１前縁指示部３ａを用いることにより、収容部４を斜め上方に引っ張ったときにも確実に警報が発生するようにし、さらに収容部４の後端付近に間隙部６を介して設けられた第２後端指示部５ｂと、外枠部２の前縁に設けられた第２前縁指示部３ｂを用いることにより、収容部４を斜め下方に引っ張ったときにも確実に警報が発生するようにすればよい。
このように構成することにより、収容部４を水平方向、斜め上方、斜め下方のいずれの方向に引っ張ったとしても確実に警報が発せられ、一層安全に収容部４を引き出すことができる。 The example in which the housing part 4 is pulled in the horizontal direction when pulling out the housing part 4 has been described above. Hereinafter, an example in which the housing part 4 is pulled obliquely upward or obliquely downward will be described.
As shown in FIGS. 11 (a) and 11 (b), when the rear end instructing section 5 is provided at the rear end of the housing section 4, the rear end instructing section 5 does not indicate the front edge even if the housing section 4 is pulled obliquely upward. Since it collides with the part 3 and gets over the leading edge indicating part 3, the accommodating part 4 is lifted and acts as an alarm.
However, as shown in FIG. 12A, when the accommodating portion 4 is pulled obliquely downward, the rear end of the accommodating portion 4 is lifted before colliding with the front edge indicating portion 3, and the accommodating portion 4 is pulled as it is. However, as shown in FIG. 12B, there is a risk that the rear end instructing unit 5 passes over the front edge instructing unit 3 and does not act as an alarm.
Thus, when it is anticipated that the accommodating part 4 is pulled diagonally downward, as shown to Fig.13 (a), the front edge instruction | indication part 3 (2nd front edge instruction | indication) is provided at the front edge of the outer frame part 2. In addition to providing the portion 3b), the gap portion 6 is provided between the rear end of the accommodating portion 4 and the rear end indicating portion 5 (second rear end indicating portion 5b). However, in this case, when the accommodating portion 4 is pulled obliquely upward, the rear end of the accommodating portion 4 rises before colliding with the front edge indicating portion 3, and the rear end indicating portion 5 moves over the front edge indicating portion 3. There is a danger of passing and not acting as an alarm.
Therefore, when there is a possibility of pulling the housing part 4 diagonally upward and diagonally downward, for example, as shown in FIGS. 4 (a) and 4 (b), the second part provided at the rear end of the housing part 4 is used. 1 When using the rear end indicating portion 5a and the first front edge indicating portion 3a provided in the vicinity of the front edge of the outer frame portion 2 via the gap portion 6, even when the accommodating portion 4 is pulled obliquely upward An alarm is surely generated, and a second rear end indicating portion 5b provided near the rear end of the accommodating portion 4 via the gap portion 6 and a second front end provided at the front edge of the outer frame portion 2. By using the edge indicating portion 3b, it is only necessary to ensure that an alarm is generated even when the accommodating portion 4 is pulled obliquely downward.
By configuring in this way, even if the accommodating portion 4 is pulled in any of the horizontal direction, obliquely upward, and obliquely downward directions, an alarm is reliably issued and the accommodating portion 4 can be pulled out more safely.

なお、本実施例における第２後端指示部５ｂはガイドリブ４ｂに設けられた切欠であり、収容部４の後端から間隙部６を介して設けられている。また、本実施例における第２前縁指示部３ｂは外枠部２の前縁に設けられており、前縁のすぐ後の部分を切削して浮き彫りにより突出させた突起である。
収容部４を斜め下方に引っ張った場合、図１３（ａ）に示したように、第２後端指示部５ｂとしての切欠の中に第２前縁指示部３ｂとしての突起が入り込み、これにより収容部４が一瞬沈み込み、警報として機能する。 In the present embodiment, the second rear end instructing portion 5b is a notch provided in the guide rib 4b, and is provided from the rear end of the accommodating portion 4 through the gap portion 6. In addition, the second front edge indicating portion 3b in the present embodiment is provided on the front edge of the outer frame portion 2, and is a protrusion that is cut out and protruded by embossing immediately after the front edge.
When the accommodating portion 4 is pulled obliquely downward, as shown in FIG. 13A, the protrusion as the second front edge indicating portion 3b enters the notch as the second rear end indicating portion 5b, thereby The accommodating part 4 sinks for a moment and functions as an alarm.

本発明においては、収容部４の後端に外枠部側面の開口部と略同じ高さの転落防止部を設けることにより、収容部４を斜め下方に引っ張った場合であっても、収容部４が転落するのを防止することができる。
即ち、収容部４を斜めに引っ張った場合、収容部４の前部が下がって傾斜状となり、収容部４の底板と外枠部２の前縁とで滑ってしまい、更に収容部４の内容物の重みも加わって、使用者の予想を越える勢いで収容部４が引き出されてしまうことがあるが、このような場合に開口部２ｂと略同じ高さの転落防止部４ａが設けられていれば、図１３（ｂ）に示したように、転落防止部４ａの上端が開口部２ｂの上端に当接するため、収容部４の飛び出しが防止される。
なお、図２乃至図４に示した実施例においては、収容部４の前後側の側壁を開口部２ｂと同じ高さとし、左右側の側壁をそれより低くして、後側の側壁における左右側の側壁の上端よりも上の部分を転落防止部４ａとして利用している。 In the present invention, even if the housing portion 4 is pulled obliquely downward by providing a fall prevention portion having substantially the same height as the opening on the side surface of the outer frame portion at the rear end of the housing portion 4, the housing portion 4 can be prevented from falling.
That is, when the accommodating portion 4 is pulled obliquely, the front portion of the accommodating portion 4 is lowered and becomes inclined, and slips between the bottom plate of the accommodating portion 4 and the front edge of the outer frame portion 2, and further the contents of the accommodating portion 4. Although the weight of the object is also added, the accommodating portion 4 may be pulled out with a momentum exceeding the user's expectation. In such a case, the fall preventing portion 4a having the same height as the opening 2b is provided. Then, as shown in FIG. 13B, since the upper end of the fall prevention part 4a abuts on the upper end of the opening 2b, the storage part 4 is prevented from popping out.
In the embodiment shown in FIGS. 2 to 4, the side walls on the front and rear sides of the accommodating portion 4 have the same height as the opening 2 b, the side walls on the left and right sides are lower than that, and the left and right sides on the rear side walls The part above the upper end of the side wall is used as the fall prevention part 4a.

収容部４の前側の側板４ｃ（以後、前板４ｃと称することがある）には、収容部４を引き出しやすくするための取っ手を設けるのが好ましい。取っ手の形状は特に限定されないが、前板３ａから突設する形状の取っ手の場合は衣服等が取っ手に引っ掛かる可能性があるので、手指を挿入して収容部４の内側に引っ掛けて引っ張ることができるように、取っ手孔４ｄを穿設する方法が好ましい。 The side plate 4c on the front side of the accommodating portion 4 (hereinafter sometimes referred to as the front plate 4c) is preferably provided with a handle for easily pulling out the accommodating portion 4. The shape of the handle is not particularly limited. However, in the case of a handle protruding from the front plate 3a, clothes or the like may be caught by the handle, so that a finger may be inserted and hooked inside the housing portion 4 to be pulled. A method of drilling the handle hole 4d is preferable so that it is possible.

取っ手孔４ｄを設けた場合、その取っ手孔４ｄから塵や埃が侵入するのを防ぐため、防塵カバー４ｅを取っ手孔４ｄに覆設するのが好ましい。防塵カバー４ｅの形状及び構造は、通常時には取っ手孔４ｄを被覆するとともに、収容部４を引き出す際には移動又は変形して取っ手孔４ｄから指を挿入できるようになる限り、特に限定されないが、例えば図１４（ａ）（ｂ）に示すように、取っ手孔４ｄの裏側に覆設した弾性を有する樹脂シート（厚さ０．３ｍｍ程度のポリプロピレン、ＰＥＴ等）を防塵カバー４ｅとする方法が挙げられる。なお、この例では防塵カバー４ｅの下側だけが接着剤等で固着されているので、取っ手孔４ｄに指を挿入したとき防塵カバー４ｅは内側に撓み、指を抜き出すと元の形状に戻って取っ手孔４ｄを塞ぎ、塵や埃の侵入を防ぐようになっている。 When the handle hole 4d is provided, it is preferable to cover the dust hole 4d with a dustproof cover 4e in order to prevent dust and dirt from entering the handle hole 4d. The shape and structure of the dust cover 4e is not particularly limited as long as it normally covers the handle hole 4d and moves or deforms when the accommodating portion 4 is pulled out so that a finger can be inserted from the handle hole 4d. For example, as shown in FIGS. 14 (a) and 14 (b), there is a method in which an elastic resin sheet (polypropylene having a thickness of about 0.3 mm, PET, etc.) covered on the back side of the handle hole 4d is used as the dustproof cover 4e. It is done. In this example, since only the lower side of the dustproof cover 4e is fixed with an adhesive or the like, the dustproof cover 4e bends inward when a finger is inserted into the handle hole 4d, and returns to its original shape when the finger is removed. The handle hole 4d is closed to prevent intrusion of dust and dirt.

収容部４の内部には、当該収容部４の形状や大きさによっては、図１５（ａ）（ｂ）に示すような、プレパラートを整理整頓するためのの縦仕切り４ｆ、横仕切り４ｇを設けることができる。なお、本例における縦仕切り４ｆは収容部４の長さ方向に延設されており、当該縦仕切り４ｆと側壁との間隔が、プレパラートの幅よりも若干広い程度であってプレパラートを立てた状態で収納できるとともに、縦仕切り４ｆ及び側壁に沿って当該プレパラートを隙間無く重ねて配列できるように構成されている。
また、本例における横仕切り４ｇは前記縦仕切り４ｆの直交方向に設けられており、収容部４内を区分けするとともに、収容部４内のプレパラートの枚数が少ない場合には、このプレパラートを立てた状態で保管するための支持具として用いることができる。但し、保管するプレパラートの種類が少なく、細かく区分けする必要がない場合や、枚数が多い場合には横仕切り４ｇは不用なので、取り外しができるようにしておくのが好ましい。 Depending on the shape and size of the storage section 4, a vertical partition 4f and a horizontal partition 4g are provided for organizing the preparation, as shown in FIGS. 15 (a) and 15 (b). be able to. In addition, the vertical partition 4f in this example is extended in the length direction of the accommodating portion 4, and the space between the vertical partition 4f and the side wall is slightly wider than the width of the preparation, and the preparation is raised. And the preparations can be arranged with no gaps along the vertical partition 4f and the side walls.
Further, the horizontal partition 4g in this example is provided in the direction orthogonal to the vertical partition 4f, and the inside of the accommodating portion 4 is divided, and this preparation is set up when the number of the prepared portions in the accommodating portion 4 is small. It can be used as a support for storing in a state. However, when there are few kinds of preparations to be stored and it is not necessary to divide them finely or when the number of sheets is large, the horizontal partition 4g is unnecessary, so it is preferable to be able to remove it.

収容部４の底板上面に凸条４ｈを設け、プレパラートをこの凸条の上に載置するようにしてもよい。この場合、例えばスライドガラスの上にカバーガラスを固着するための接着剤が垂れて収容部４の底面に溜まったとしても、プレパラートが収容部４に接着されてしまうようなトラブルを防止することができる。
なお、凸条４ｈの形状は特に限定されないが、図１５（ａ）（ｂ）に示したように、プレパラートの配列方向に延設された２本の直線状とすれば、形状が簡単で安価に製造でき、清掃もしやすいので好ましい。 A protrusion 4h may be provided on the upper surface of the bottom plate of the accommodating portion 4, and the preparation may be placed on the protrusion. In this case, for example, even if an adhesive for fixing the cover glass on the slide glass hangs down and accumulates on the bottom surface of the housing portion 4, it is possible to prevent a trouble that the preparation is adhered to the housing portion 4. it can.
