Then, at the predetermined time t2, the receiving member 34 releases the temporary holding of both the first tablet 10 and the second and subsequent tablets 10. For the second and subsequent tablets 10, the advancement speed (movement speed) of the front blade 41 among the opposed blades 41 and 42 is changed at the predetermined time t2. That is, for the second and subsequent tablets 10 processed after the automatic adjustment at the predetermined time t2, it is only necessary to change the advance speed of the front blade 41 from high speed to low speed at the predetermined time t2.

At this time, the relative distance G between the groove bottom of the upstream partial path 32a of the guide path 32 and the groove bottom facing surface of the guide plate 37 is in a state where the closing distance is narrow. Therefore, the tablet 10 is temporarily retained at the upper end (upstream position) of the guide path 32 (see FIG. 3C).
- the guide plate 37 moves to increase the relative distance G (see FIG. 3D).
- the guide plate 37 stops moving and the relative distance G is fixed.
- the tablet 10 falls through the upstream partial path 32a of the guide path 32 (see FIGS. 6A and 6B). Since the relative distance G has already been automatically adjusted when the tablet 10 falls, the relative distance G is adapted to the thickness of the tablet 10. Therefore, the tablet 10 falls smoothly and quickly while maintaining the posture in which the thickness direction is directed in the front-rear direction, and reaches the cutting position 33 (see FIG. 6C).
- the tablet 10 that has reached the cutting position 33 stops by contacting the receiving member 34 and is positioned between the two receiving members 34, that is, at the center between the left arm 34 b and the right arm 34 c, and above the slit 35.

- the switching member 81 rotates, the rear tablet passage 81a positioned on the partition plate 82 advances while drawing an arc (see FIG. 13C). Then, the cut piece 11 is pushed up along the inclined surface of the partition plate 82, and at this time, the dust 12 adhered to the cut piece 11 is rubbed against the upper surface of the partition plate 82, and the dust 12 on the partition plate 82.

Therefore, to supplement the explanation here, it is good for the shaft rotation of the switching member 81 to always rotate at a constant speed. Further, the cutting piece 11 may not be rotated until it falls, and may be rotated when it is detected that it has been dropped. The detection of the fall of the cut piece 11 can be performed, for example, when the cut piece 11 has successfully passed the tablet receiving location X4 of the separation mechanism 80. The passage can be confirmed by, for example, the output of the above-described tablet presence / absence detection sensor. Various settings can also be made for the rotation start time. For example, the rotation may be started after a predetermined delay time has elapsed from the passage detection.
- the delay time there is a time required for the cut piece 11 that has fallen from the holding mechanism 30B and entered the tablet passage 81a to settle on the partition plate 82 and to be in a settling state.
- the delay time value determined under such conditions is used, the dust 12 is efficiently separated.
- the basic function and effect that the dust 12 is dropped and separated from the dust separation hole 82a in the process of the cutting piece 11 moving while rolling or rubbing on the partition plate 82 can be obtained more accurately. It is done.
- the cutting piece 11 moves on the partition plate 82, the inclined surface is moved up against the inclination, and the dust 12 adhering to the cutting piece 11 is efficiently screened out on the partition plate 82. It is considered that the further effect of shifting can be obtained more accurately.

Abstract
Description
その装置の裁断機構は、対向刃を近接離間させて錠剤を裁断するものであり、裁断動作規定手段は、対向刃を近接移動させて錠剤を裁断する際、対向刃が錠剤を挟むまでは保持機構による錠剤保持を継続させ、対向刃が錠剤を挟んでからは保持機構による錠剤保持を解除させて錠剤を対向刃だけで挟持させ、保持機構による錠剤保持が解除されてから対向刃を錠剤に切り込ませるというものである。
この装置は、錠剤落下経路のうち裁断位置より上流の部分を覆う溝深規定部材と、錠剤落下経路の溝底と溝深規定部材の溝底対向面との相対距離を拡縮する厚み調整機構と、錠剤の厚さ情報を取得して厚み調整機構を作動させることにより、相対距離を錠剤の厚さに適合させる制御装置とを具備している。
上記相対距離を錠剤の厚さに適合させることができれば、裁断時の錠剤保持状態が安定し、裁断片の量目の変動を小さくすることができる。また、自動的に適合できれば、調整負担が軽減される。
なお、制御装置が錠剤の厚さ情報を取得する手段としては、着脱式錠剤カセット付属のデータ担体からの読出や、操作部からの直接入力、上位装置からの通信回線経由ダウンロードなどがある(特願2011−042955参照)。
従って、サポート手段が存在しなければ、機能せず、使えない。例えば、ダウンロード方式は通信設備のない所では使えず、データ担体からの読出は錠剤カセット等に付属品が無いと使えず、操作入力方式は面倒なうえ誤入力のおそれもある。ダウンロード方式やデータ担体読出方式でもデータ登録作業ではデータ誤入力のおそれがなくなる訳でない。このように、上記の錠剤分割装置は、厚さの異なる各種錠剤に対して適合させる調整の負担を単独で軽減できる実施形態まで明らかになった訳ではない。
さらに、データ準備の済んでいない薬剤(たとえば新薬や急遽使用することになった薬剤)に対して迅速且つ適切に対応できない。
このような点について、さらに研究開発を進めて、次のような発明をするに至った。
このように、裁断状態の変動要因であるとともに変動量の増幅要因でもあると考えられる保持機構からの反力が生じないように改良したため、割れが安定して、裁断片の量目の変動が更に小さくて済むものとなっている。
また、この錠剤分割装置では、落下錠剤案内部材が本体部の筐体内で支持フレームに対しネジ止め等にて固定されており、裁断機構の刃が刃進退部材に対してネジ止め等で直に或いはネジ締結力利用の挟持等にて間接的に固定されている。
そして、それに対する直截的な作業負担軽減策として、刃進退部材に対する刃の装着態様をスライダのような摺動にて係合する方式などで着脱式にすることが考えられる。
従って、裁断機構の刃を容易かつ気軽に着脱しうる錠剤分割装置を実現することができれば、裁断品質を高い精度で安定させることが容易になり、裁断片の量目を安定させることができる。
また、篩いは、そのような制約が無いうえ簡素かつ安価であるという観点からは使い易い。ところが、一般的な使い方ではなかなか満足できる物ができなかった。例えば、傾斜ガイドに篩いを採用してその上を自重で滑落させた場合、傾斜が緩すぎると裁断片が落下せず、他方、傾斜が急すぎると粉塵が篩い分けできず、傾斜の妥協点が見いだし難い。また、緩衝用バッファに篩いを採用し、これを上下反転させる方法も考えられる。ところが、この方法では、反転速度を上げると裁断片及び粉塵があらぬ所へ飛んでしまうため、高速化が難しく、能率が上がらない。
そこで、篩い式でも能率の良い錠剤裁断粉塵分離機構を実現できれば、より確実に粉塵が分離された裁断片を得ることができ、より量目が安定した裁断片を、効率よく供給することができることになる。
しかも、錠剤落下経路切替部材と仕切板との相対移動が擦過運動の様なものであり、それによって錠剤落下経路の下端面が引戸風に開けられてから裁断片が落下するので、全部材が上下反転したり下端面が扉風に開けられるのと異なり、錠剤落下経路の入れ替え速度を上げても、裁断片の落下状態が安定するとともに落下先が適度に絞られる。このように、本発明によれば、篩い式であっても能率良く粉塵を分離することができる。
なお、各図では、便宜的に、発明の説明に必要な構成や関連する構成を明確に図示することとし、例えば、ボルト等の締結具,ヒンジ等の連結具,ギヤ等の伝動部材,モータドライバ等の電気回路の詳細,コントローラ等の電子回路の詳細などを省略した。これにより、発明の特徴をより簡明に説明できるようになっている。
これらのうち、制御装置23と中継部26と支持フレーム28と保持機構30と裁断機構40と電源部は、本体部(筐体)24に内蔵されている。操作部22と錠剤フィーダベース部27は、本体部24に固定的に装着されており、図示していない操作面及びカセット装着面が筐体外面に露出されている。また、錠剤カセット21は、錠剤フィーダベース部27に着脱自在に装着されており、受器25は、本体部24の底部の前面開口から引き出し自在に挿着されている。
本体部24の中央部に配置された保持機構30及び裁断機構40は、支持フレーム28に取り付けられており(図1(b),(c)参照)、そのうち保持機構30は、支持フレーム28と同じ鉛直の姿勢をとり、裁断機構40は保持機構30と垂直な水平の姿勢をとっている。
裁断機構40は、裁断位置の錠剤10を裁断して左右2個の裁断片(錠剤裁断片)10b,10cに分割するものである(図6参照)。なお、ここでは、装置正面から装置に向かって左側の裁断片を左側裁断片10bとし、向かって右側の裁断片を右側裁断片10cとする。
中継部26は、保持機構30の下側に配置されており、収集用ガイドや緩衝用バッファを具備している。そして、中継部26は、保持機構30の案内路32のうち左側分岐経路32bから落下した裁断片10bを左側受器25bへ送り込み、保持機構30の案内路32のうち右側分岐経路32cから落下した裁断片10cを右側受器25cへ送り込む(図6(f)参照)。
なお、両裁断片10b,10cを総て一纏めに収容してもよい。この場合、単体の幅広容器を使用する。また、本実施例では、受器25、これに裁断片10b,10cを導く中継部26、操作部22及び制御装置23は、装置運搬の容易化等のために装置に一体的に設置されている。これらの構成は、装置に分離可能に設置されていてもよいし、装置とは別体でもよい。
案内部材31には、錠剤通過検出センサ39が設置されている。錠剤通過検出センサ39は、錠剤カセット21から落下して案内路32に投入された錠剤10が案内路32の上流部分経路32aの所定位置を通過したことを検出するものである。なお、錠剤通過検出センサ39としては、非接触で検出できる光学式のものが使い易い。本実施例では、案内路32の上流部分経路32aの両脇に対向配置された発光素子39bと受光素子39cを設置している。
案内部材31の両面(前面及び後面)のうち前向きの表面には、落下する錠剤10を案内する案内路32が形成されている(図1(d),図2参照)。
案内路32は、案内部材31の表面に彫り込みやプレス等によって形成された溝(溝状部)であり、案内部材31の上端から下端まで連なっている(図2(a)参照)。具体的に説明すると、案内路32は、錠剤落下方向に延在する3つの内側面(案内路内側面)に囲まれており、錠剤落下方向に延在する開口部(溝開口)を備えている。3つの内側面とは、開口部に対向した溝底面とその両側に配置された左右の側面(両側面)である。案内路32の溝底面(平面部)32gは、平面形状であり、錠剤の落下方向(鉛直方向)に延在している。そして、案内路32の途中の位置には、後述のスリット35が形成されている。
受止部材34は、その二分岐に対応しており、案内路32から各分岐通路に連なる経路の開閉に用いられる左右一対のアーム(左側経路開閉部材,右側経路開閉部材)34b,34cで構成されている。両アーム34b,34cは、後述のスリット35を中心として、左右対称に配置されている。各開閉部材34b,34cは、いずれも、制御装置23の制御に従って揺動する。具体的には、左アーム34bは上流部分経路32aから左側分岐経路32bへの分岐口を開閉する開閉動作を行い、右アーム34cは上流部分経路32aから右側分岐経路32cへの分岐口を開閉する開閉動作を行う。
制御装置23は、このような動作制御を行い得るものである。つまり、まず、対向刃のうちの一方の刃を所定の到達位置に先に到達させ(挟持位置確定動作)、その状態で、他方の刃を一方の刃に向けて近接移動させ、両刃で錠剤を挟持するという動作制御をも行い得るものである。この場合、各刃によって、近接移動動作の内容が異なっている。一方の刃の挟持位置確定動作も近接移動動作の一部に含まれる。
こうして、対向刃41,42に錠剤10を挟持させてから裁断させるまで間の時期であって対向刃41,42のうちの前刃41の進出速度の変更と受止部材34による錠剤10の一時保持の解除との双方を行う時期である所定時期t2が、駆動電流検出部材47による駆動電流検出信号Ifに基づいて、錠剤10の厚さに適合するよう自動調整される。
なお、繰り返しになる詳細説明は割愛するが、二番目以降の錠剤10が錠剤カセット21から排出されて保持機構30の案内路32に落下投入されるとき、案内路32の上流部分経路32aの溝底と案内板37の溝底対向面との相対距離Gは錠剤10の厚さより少しだけ広い状態で固定されている(図3(e)参照)。また、前刃41は進退位置P1にとどまった状態であり、対向刃41,42の対向間隙は相対距離Gより少しだけ広くなった状態である(図4(h)参照)。
こうして、二番目以降の錠剤10については、最初の錠剤10を利用して済ませて自動調整の効果を享受することができて、安定な状態で而も迅速に、裁断が遂行される。
上記第1実施例の錠剤分割装置の錠剤厚情報取得手段は、錠剤の厚さ情報を装置内計測にて取得するだけであり、錠剤の厚さ情報を外部から取得するようになっていないが、外部からの取得を排除する訳でない。例えば、装置内計測での取得に加え、外部からの取得も試行して、外部から取得できたときには、その値そのままか少し小さめの値を案内路の溝底と案内板の溝底対向面との相対距離の初期値に用いるようにしても良い。
上記実施例では、所定時期t2の自動調整を前刃41の駆動電流に基づいて行っているが、所定時期t2の自動調整は、奥刃42の駆動電流に基づいて行うようにしても良く、対向刃41,42両方の駆動電流たとえば合計電流に基づいて行うようにしても良い。
そして、保持機構30Aは、錠剤フィーダベース部27と中継部26との間に配置された案内部材(落下錠剤案内部材)31Aと、一対の受止部材34と、案内板37Aと、固定覆板36とを備えている。案内部材31Aは、その表面に形成された錠剤落下経路(案内路)32Aやスリット35などを備えている。また、受止部材34は、案内路32Aを開閉するものであり、案内路32Aに収められた状態で案内部材31Aに装着されている(図7(b)~(d),図8参照)。案内板37Aは、案内路32Aの上流部分に入り込んで覆っている。固定覆板36は、厚み調整機構(不図示)と、案内部材31Aの下半分の表面・前面を覆っている。なお、図8(b)~(d)では、固定覆板36を透明な部材として透視状態の案内路32Aと共に示している。
裁断機構40Aは、前刃41と奥刃42とからなる対向刃41,42を具備している。
前刃41は、前刃進退部材43によって裁断位置33のスリット35の前方に支持されており、奥刃42は、奥刃進退部材44に支持されている。前刃41は、制御装置23Aの制御に従って後方のスリット35に向けて進退移動するものである。奥刃42は、制御装置23Aの制御に従ってスリット35を通過しながら裁断位置33の錠剤10に向けて前方へ進退するようになっている。両刃は、いずれも制御装置23Aの制御に従ってスリット35に向けて進退する。
なお、本実施例の錠剤分割装置20Aでは、第1実施例の装置20と異なり、案内路32Aのうち裁断位置33より下流側部分が裁断位置33の直下で幅が広がっている(図8(a)参照)。そして、この幅広に広がった裁断位置33の直下の幅広経路に、第1実施利と同様の受止部材34が設置されている。
なお、これらの基本構成のように、第1実施例と共通の構成には同様の符号を付しその説明を省略することがある。
また、本体部24の筐体内の中央部には、保持機構30Aと裁断機構40Aが支持部材28Aに取り付けられており(図7(b),(c)参照)、そのうち保持機構30Aは、支持部材28Aと同じ鉛直の姿勢であり、裁断機構40Aは保持機構30Aと垂直な水平の姿勢である。なお、保持機構30Aと裁断機構40Aを支持部材28Aとは別の支持部材で支持しても良い。
図9に示されるように、裁断機構40Aの前刃41は、錠剤10に切り込むための刃先部41aと、この刃先部41aを前刃進退部材43に装着させるための刃元部41bとからなるものである。後者の刃元部41bには、上下に延び、下端部にはテーパ部41cが形成された凸部41dが左右両側端に設けられている。この凸部41dの下端を前刃進退部材43の凹部の上端に合わせ、前刃41をそのままの姿勢で真っ直ぐ下降させると、前刃41と前刃進退部材43とが摺動にて係合されるようになっている。つまり、前刃41の凸部41dの下端部及び前刃進退部材43の凹部は、摺動部(取付用摺動部)であると共に係合部(取付用摺動係合部)である。また、前刃進退部材43が固定された状態では、前刃進退部材43に係合された前刃41をそのままの姿勢で真っ直ぐ上昇させると、前刃41と前刃進退部材43とが摺動にて分離可能である。
なお、繰り返しの詳細説明は割愛するが、奥刃42も、前刃41と同様の構造であり、奥刃進退部材44に摺動にて結合させたり分離させたりすることができ、刃交換治具であるリムーバ60やセッター70にも摺動にて結合させたり分離させたりすることができる。
治具本体部61の左右両端面には、上述した案内部材31Aの凹部31Uと同様の凹部62が形成されている。従って、治具本体部61は、案内部材31Aを筐体外に取り外した状態では、これに代えて支持部材28Aに対して摺動にて係合させたり分離させたりすることができる。
また、弾性部材67は、その上端部が固装部材65に固定されており、下端部は可動端部68になっている。可動端部68は、鋭角に曲げ戻されて切込63の前を斜めに横切っている。従って、支持部材28Aにリムーバ60を係合させると、前刃進退部材43に装着された状態の前刃41を刃保持部64によって捕捉することができ、更に支持部材28Aから前刃41を捕捉したリムーバ60を外すと、前刃41が前刃進退部材43から取り外される。
また、これらの部材のうち治具本体部71及び固装部材75は、リムーバ60の治具本体部61及び固装部材65と同じものでも良く、弾性部材77も素材は弾性部材67と同じで良い。ただし、弾性部材77の折り曲げ形状は、弾性部材67とは構成が異なる。
また、弾性部材77は、上端部が固装部材75に固定され、下端部が可動端部78になっている。可動端部78は、鈍角に曲げられていて切込73の前を斜めに横切っている。つまり、切込73に対する可動端部78の傾斜は、例えば右下がりであり、上述した可動端部68の右上がりとは逆である。このような構成の弾性部材77は、例えば可動端部68に比べて掛止力が弱い。従って、前刃41を刃保持部74に保持させて治具本体部71を支持部材28Aに係合させると共に前刃41を前刃進退部材43に係合させて装着した後、治具本体部71を支持部材28Aから外すと、前刃41が前刃進退部材43に装着された状態が維持され、前刃41が刃保持部74から外れるようにすることができる。
なお、錠剤の裁断動作については、基本的には、第1実施例の錠剤分割装置20と同様であるので、ここではその詳細な説明を省略する。
対向刃41,42の交換は、先ず保持機構30Aを取り外し(図7(c),図8(c),参照)、次にそこへリムーバ60を抜き差しして古い対向刃41,42を裁断機構40Aから取り外す(図10(b)~(d),図7(d)参照)。その後、セッター70を抜き差しして新しい対向刃41,42を裁断機構40Aに装着する(図11(b)~(d)参照)。そして、最後に保持機構30Aを戻す(図7(a),(b)参照)。このような簡単な作用によって、迅速且つ確実に刃を交換することができる。
なお、第2実施例では、刃交換時に対向刃41,42を移動させるようになっていなかったが、刃交換時には操作部22の操作等にて対向刃41,42の対向間隙を狭めておくようにしても良く、そのようにした方が、刃交換治具60,70を薄くできるうえ、裁断機構40Aを稠密に実装できるので、本体部24を小形化することができる。
また、第2実施例では、裁断機構40Aが、対向させた一対の刃先を進退させて錠剤10を裁断するようになっていたが、裁断可能なら片刃でも良い。
さらに、第2実施例では、錠剤10が均等分割されていたが不均等な分割でも良い。
なお、それらの図示に際しては、簡明化等のため、ボルト等の締結具や,ヒンジ等の連結具,電動モータ等の駆動源,タイミングベルト等の伝動部材,モータドライバ等の電気回路,コントローラ等の電子回路の詳細などは図示を割愛し、発明の説明に必要なものや関連するものを中心に図示した。
そして、錠剤フィーダベース部27及び錠剤カセット21は、第1実施例同様、制御装置23Bの制御に従って錠剤カセット21から錠剤を一錠ずつ排出し、排出された錠剤を保持機構30Bにその上端から送り込む。保持機構30Bは、上端側から落下して来た錠剤を裁断位置に一時保持する受止部材を備えている。また、裁断機構40Bは、片刃か対向刃か回転刃かといった刃物にて裁断位置の錠剤を裁断して二個の裁断片11,11に分割する。
保持機構30Bと裁断機構40Bと中継器80は、本体部24の筐体内の中央部に位置するように、支持部材28B又は他の支持部材に取り付けられている。
従って、このような基本構成のように、第1実施例と共通の構成には同一の符号を付し、その説明を省略することがある。
また、複数の錠剤通路81aは、いずれも、裁断片11が通過可能な大きさであり、開口する上端面及び下端面は、仕切板82の上面より狭くなっており、仕切板82によって下端面を覆うことができる。さらに、二つの錠剤通路81aは、切替部材81が180°軸回転する度に交互に入れ替わる所に形成されている。
つまり、切替部材は、複数の錠剤通路のうちのいずれか一つを仕切板の上方に位置させる複数の回転位置(回転位相)に回転可能である。
シュート84は、例えば滑り台や軒樋のような案内部材であり、斜めに設置されている。従って、裁断片11はシュート84を滑落して下方の裁断片受器93に導かれる。
回転駆動機構85は、制御装置23Bの制御に従って回転軸を駆動するモータや減速ギヤ等で構成されている。そして、回転軸の先端部は、切替部材81の錠剤通路81aに嵌め込まれており、切替部材81は軸回転可能になっている。
また、傾斜支持台83は、後寄りの部位に形成された粉塵落下経路(以下、粉塵通路と称する)83aと、前寄りの部位に形成された回転軸挿通穴83bとを備えている。粉塵通路83aは、錠剤通路81aとほぼ同じかそれより広い断面を持っている。また、回転軸挿通穴83bは、回転軸を挿通させて軸回転可能に支持する軸受兼用の穴である。なお、回転軸は、回転駆動機構85から出て切替部材81に至る位置に延在する状態で配置されている。なお、粉塵通路83a及び回転軸挿通穴83bは、傾斜支持台83を傾ける前の状態で鉛直な貫通縦穴状であるので、傾斜支持台83と同じ角度だけ後傾している。しかも、回転軸挿通穴83bを貫く回転軸が仕切板82の前方延長板に対して垂直になっている。
他方、二つの錠剤通路81aは、いずれも、切替部材81の軸回転に伴って後へ回ってくると、傾斜支持台83の傾斜状態に基づき高度を下げることになる。そして、仕切板82の上にきて下端面を仕切板82に覆われる状態になる。
他方、第2粉塵受器92は、裁断片受器93を挿抜自在に収容しうる外箱としても用いられる。そして、この第2粉塵受器92に裁断片受器93を収容したとき、裁断片受器93の底の下面が第2粉塵受器92の内底面より少し高いところに位置するようになっている。つまり、両底の間に粉塵12を収容するための間隙が確保されている。
底網93aは、裁断片11は通過させないがそれより小さな粉塵12は通過させる細かさの目を持った網体である。そして、第2粉塵受器92に裁断片受器93を重ねたものを一緒に本体部24に挿着すると、裁断片受器93は、シュート84の下方に位置する。従って、シュート84を滑り落ちた裁断片11は、裁断片受器93の解放上面から受器93内に受け入れられて収容される。また、裁断片11と一緒に裁断片受器93に入ってきたもののうち、裁断片受器93の中にとどまれずに底網93aを通過してさらに落下した粉塵12は、第2粉塵受器92に収容される。
しかも、粉塵12を収容した錠剤通路81aが前進するのと同時に、空の錠剤通路81aが後進して両者が入れ替わる構造であり、迅速に次の裁断片11を分離機構80に受け入れることが可能な状態になるので(図13(d)参照)、錠剤の裁断を短い周期で繰り返し能率良く行うことができる。
なお、本実施例では、錠剤や裁断片11を検出する錠剤有無検出センサについて言及しなかったが、錠剤や裁断片11の通過するところに錠剤有無検出センサを配置して、錠剤や裁断片11が正常に落下しているか否かを検知するようにしても良い。錠剤有無検出センサは、非接触のフォトセンサが使いやすい。例えば、図14(a)に示される錠剤フィーダベース部27の錠剤通過点X1や、保持機構30Bの錠剤通過点X2、裁断機構40Bの錠剤裁断位置近傍X3、分離機構80の錠剤受入箇所X4、分離機構80の錠剤放出箇所X5などのうち適宜な所に設けることが考えられる。
さらに、錠剤分割装置20Bについて、本実施例で錠剤分割装置20Bに設けられていた操作部22は必須でなく、例えば、錠剤が投入されたらそれに応じて一連の動作が開始されるようにしても良い。錠剤の自動逐次供給が不要であれば、錠剤フィーダベース部27や錠剤カセット21も必須でない。
