Description

本発明は、内部に収容した錠剤・カプセル等の薬剤を所定数ずつ排出する薬剤カセッターに関し、更に詳しくは、支持台に着脱時に収容された薬剤を不用意に排出させないように改良した薬剤カセッターに関する。   The present invention relates to a medicine cassette that discharges a predetermined number of medicines such as tablets and capsules contained therein, and more particularly, to a medicine cassette that is improved so as not to inadvertently discharge the medicine stored in a support base when it is attached or detached. .

一般に、薬剤カセッターは、内部に錠剤等の薬剤を収容する薬剤収納部と、該薬剤収納部内に回転自在に設けられた分配ローターと、該分配ローターの回転軸に固着された従属ギヤとを具備してなり、薬剤分配装置を構成する支持台に着脱自在な構成からなる。   In general, a drug cassette includes a drug container that stores a drug such as a tablet therein, a distribution rotor that is rotatably provided in the drug container, and a slave gear that is fixed to a rotation shaft of the distribution rotor. Thus, it is configured to be attachable to and detachable from a support base constituting the medicine distribution device.

かかる薬剤カセッターを支持台に装着すると、支持台に具備された駆動手段に連結された主動ギヤに薬剤カセッターの従属ギヤが噛合し、駆動手段を作動させることにより分配ローターが回転し、薬剤整列路から排出孔に所定数ずつ薬剤が排出されることとなる。   When such a medicine cassette is mounted on the support base, the subordinate gear of the medicine cassette meshes with the main gear connected to the drive means provided on the support base, and the distribution rotor is rotated by operating the drive means, whereby the medicine alignment path A predetermined number of medicines are discharged from the discharge hole to the discharge hole.

ところで、薬剤を補給したり、薬剤の種類を交換したり等する際には、薬剤カセッターを支持台から取り外すのであるが、薬剤カセッターに設けられた分配ローターは回転自在であるため、薬剤カセッターの着脱時や薬剤カセッターの交換・薬剤補給時等に、分配ローターが不用意に回転し、収納された薬剤が排出されることがある。   By the way, when replenishing a medicine or exchanging the kind of medicine, the medicine cassette is removed from the support base, but since the distribution rotor provided in the medicine cassette is rotatable, the medicine cassette The dispensing rotor may rotate inadvertently and the stored medicine may be discharged when attaching or detaching, or when changing or replenishing the medicine cassette.

かかる薬剤の排出を防止するため、例えば、図6に示すように、薬剤カセッター40を支持台(図示せず)から取外すとバネ付勢により従属ギヤ41を係止し、且つ薬剤カセッター40を装着すると従属ギヤ41の係止を解除する係止部材43を設けるという手段が考えられる。
かかる係止部材43によれば、従属ギヤ41の歯41a と歯41a の間(歯溝41b )に係止山部43a が嵌合することとなるから従属ギヤ41はしっかり係止されて回転することはなく、従って、薬剤カセッター40を取外した状態では分配ローター44が回転しないから薬剤の不用意な排出を防止する有効な手段と考えられる。
In order to prevent the discharge of the medicine, for example, as shown in FIG. 6, when the medicine cassette 40 is removed from the support base (not shown), the slave gear 41 is locked by the spring bias and the medicine cassette 40 is attached. Then, a means of providing a locking member 43 for releasing the locking of the dependent gear 41 can be considered.
According to the locking member 43, the locking ridge 43a is fitted between the teeth 41a and 41a of the dependent gear 41 (tooth groove 41b), so that the dependent gear 41 is firmly locked and rotates. Therefore, since the distribution rotor 44 does not rotate when the medicine cassette 40 is removed, it is considered to be an effective means for preventing inadvertent discharge of the medicine.

しかしながら、上記手段にあっては、薬剤カセッター40を取外す際に、係止部材43の係止山部43a が、従属ギア41の歯41a と当接して干渉し合う虞れも否定できず、かかる状態では、その後、従属ギヤ41が僅かに回転して係止山部43a と従属ギヤ41の歯溝41b とが嵌合することとなる。   However, in the above means, when removing the medicine cassette 40, it is impossible to deny the possibility that the locking crest 43a of the locking member 43 abuts against the teeth 41a of the dependent gear 41 and interferes with each other. In this state, after that, the dependent gear 41 is slightly rotated, and the locking ridge 43a and the tooth groove 41b of the dependent gear 41 are fitted.

このように僅かに従属ギヤ41が回転すると、それに伴い分配ローター44も回転するから薬剤が排出される虞れがある。
例えば、分配ローター44の薬剤整列路45の数が従属ギヤ41の歯41a の数の約2倍であれば、上記歯41a から歯溝41b に従属ギヤ41が回転すると、分配ローター44にあっては、取外し時に排出孔46に位置する薬剤整列路45' (既に薬剤が排出されて空になった部位、換言すると排出済の薬剤整列路45' )が移動し、排出孔46にその隣の薬剤整列路45" が位置することになって薬剤が排出されることとなる。
If the subordinate gear 41 is slightly rotated in this way, the distribution rotor 44 is also rotated accordingly, so that the medicine may be discharged.
For example, if the number of medicine alignment paths 45 of the distribution rotor 44 is about twice the number of teeth 41a of the subordinate gear 41, when the subordinate gear 41 rotates from the tooth 41a to the tooth groove 41b, the distribution rotor 44 The drug alignment path 45 ′ (the part where the drug has already been discharged and empty, in other words, the discharged drug alignment path 45 ′) located in the discharge hole 46 at the time of removal moves and moves to the discharge hole 46 next to it. The medicine alignment path 45 "is positioned and the medicine is discharged.

また、従属ギヤ41の歯41a と薬剤整列路45の数が略同じであっても、装置停止時に僅かに分配ローター44が回転し過ぎた結果、排出孔46に排出済の薬剤整列路45' が位置せずに排出済の薬剤整列路45' と隣の薬剤整列路45" との中間部分が位置していた場合には、係止山部43a と従属ギヤ41の歯溝41b の干渉し合った後に従属ギヤ41が僅かに回転して嵌合すると、隣の薬剤整列路45" が排出孔46に位置することになって薬剤が排出されることとなる。   Even if the number of the teeth 41a of the subordinate gear 41 and the number of the drug alignment paths 45 are substantially the same, the distribution rotor 44 is slightly rotated when the apparatus is stopped. If the intermediate portion between the discharged drug alignment path 45 'and the adjacent drug alignment path 45 "is positioned without being positioned, the interference between the locking crest 43a and the tooth groove 41b of the subordinate gear 41 occurs. When the subordinate gear 41 is slightly rotated after the engagement, the adjacent medicine alignment path 45 "is positioned in the discharge hole 46 and the medicine is discharged.

そこで、本発明はこのような問題を解決すべくなされたものであり、ギヤの歯数等に拘らず、支持台から取外した状態のみならず、支持台への着脱時に於いても確実に分配ローターの回転を阻止して不用意に薬剤を排出させない薬剤カセッターを提供することを課題とする。   Therefore, the present invention has been made to solve such problems, and reliably distributes not only the state of removal from the support base, but also when it is attached to or detached from the support base, regardless of the number of gear teeth. It is an object of the present invention to provide a medicine cassette that prevents rotation of the rotor and prevents the medicine from being discharged carelessly.

本発明は、薬剤分配装置を構成する支持台2に着脱自在で、且つ収容された錠剤等の薬剤を所定数ずつ排出する回転自在な分配ローター11が設けられてなる薬剤カセッターであって、カセッター本体3には、該カセッター本体3を前記支持台2から取外した際に分配ローター11の周壁11aを係止し、且つカセッター本体3を支持台2に装着した際に前記分配ローター11の係止を解除する係止手段が設けられ、前記分配ローター11の周壁11aには、薬剤を整列させるべく凹状に形成された複数の薬剤整列路16と、隣り合う薬剤整列路16同士の間に形成される凸条面32とが設けられ、前記係止手段は、前記薬剤整列路16が薬剤排出位置Bにあるときに、薬剤整列路16に嵌入しうる係止部23を具備してなり、係止部23には、前記凸条面32の隅部32aに当接する傾斜面が形成されていることを特徴とする。
The present invention is a medicine cassette that is provided with a rotatable dispensing rotor 11 that is detachably attached to a support 2 constituting a medicine dispensing apparatus and that discharges a predetermined number of medicines such as stored tablets. The main body 3 locks the peripheral wall 11a of the distribution rotor 11 when the cassette main body 3 is removed from the support base 2, and the distribution rotor 11 locks when the cassette main body 3 is mounted on the support base 2. Is provided between the adjacent drug alignment paths 16 and a plurality of drug alignment paths 16 formed in a concave shape on the peripheral wall 11a of the distribution rotor 11 to align the drugs. a convex surface 32 is provided that, the locking means, when the drug alignment path 16 is in the drug discharge position B, Ri name comprises a locking portion 23 which can be fitted to the drug alignment path 16, In the locking part 23 Characterized in that the inclined surface abutting the corner portion 32a of the convex surface 32 is formed.

上記構成からなる薬剤カセッターは、支持台2 から取外した際に、係止手段によって分配ローター11が係止されるので、カセッター本体3 の運搬時や薬剤の詰め替え時等に不用意に分配ローター11が回転することはなく、従って、収容された薬剤が排出孔17から不用意に排出されることはない。
かかる係止手段であれば、回転すると薬剤が排出される分配ローター11を係止するものであるため、回転を阻止する手段として直接的であり、又、例えば、分配ローターの従属ギヤを係止するとした場合に考えられる、従属ギヤの歯と係止部材とが干渉し且つ取外し後に分配ローターが僅かに回転するという虞れもなく、確実に分配ローター11を係止することができるのである。
When the medicine cassette having the above structure is detached from the support base 2, the distribution rotor 11 is locked by the locking means. Therefore, the distribution rotor 11 is inadvertently used when the cassette body 3 is transported or when the medicine is refilled. Therefore, the stored medicine is not inadvertently discharged from the discharge hole 17.
Such a locking means locks the distribution rotor 11 from which the medicine is discharged when rotated, and thus is a direct means for preventing rotation, and for example, locks the subordinate gear of the distribution rotor. In this case, it is possible to reliably lock the distribution rotor 11 without the possibility that the teeth of the slave gear and the locking member interfere with each other and the rotation of the distribution rotor slightly after removal.

また、前記分配ローター11の周壁11a には、薬剤を整列させる複数の薬剤整列路16が設けられ、前記係止手段が、薬剤排出位置B にある薬剤整列路16に嵌入しうる係止部23を具備していれば、薬剤を排出する出口の部分に係止具本体22が嵌入することとなるから、薬剤を不用意に排出させないという効果を最も確実に達成できる。
ここで、薬剤排出位置とは、分配ローター11に設けられた複数の薬剤整列路16のうちで、既に薬剤が排出されて空になった部位をいう。
尚、薬剤排出位置にある薬剤整列路16は、既に薬剤が排出されているので薬剤が存在することはなく空の状態であるから、係止具本体22は確実に嵌入できることとなる。
The peripheral wall 11a of the distribution rotor 11 is provided with a plurality of drug alignment paths 16 for aligning drugs, and the locking means 23 can be fitted into the drug alignment path 16 at the drug discharge position B. Since the locking tool main body 22 is inserted into the exit portion for discharging the medicine, the effect of preventing the medicine from being discharged carelessly can be achieved most reliably.
Here, the drug discharge position refers to a part of the plurality of drug alignment paths 16 provided in the distribution rotor 11 that has already been discharged after being discharged.
Since the medicine alignment path 16 at the medicine discharge position is empty because the medicine has already been discharged, the locking tool main body 22 can be securely inserted.

本発明の薬剤カセッターでは、係止部23はカセッター本体3の薬剤収納部10の周面10bの後方側に穿設された窓部20を通過して薬剤整列路16に嵌入するものであることを特徴とする。
In the medicine cassette of the present invention, the locking part 23 is inserted into the medicine alignment path 16 through the window part 20 formed on the rear side of the peripheral surface 10b of the medicine storage part 10 of the cassette body 3. It is characterized by that.

本発明の薬剤カセッターでは、前記係止手段は係止具本体22を備え、該係止具本体22の一端側には前記係止部23が形成され、係止具本体22の他端側にはカセッター本体3を支持台2に装着した際に躯体1に押圧されて係止部23を薬剤整列路16から離反させる作用部24が形成されていることを特徴とする。
In the medicine cassette according to the present invention, the locking means includes a locking tool body 22, the locking part 23 is formed on one end side of the locking tool body 22, and the locking tool body 22 is connected to the other end side of the locking tool body 22. Is characterized in that an action portion 24 is formed which is pressed by the housing 1 when the cassette body 3 is mounted on the support base 2 and separates the locking portion 23 from the medicine alignment path 16.

本発明の薬剤カセッターでは、前記係止具本体22は、薬剤収納部10回転自在に軸支されることを特徴とする。
The drug Kasetta of the present invention, the engaging end stop body 22, characterized in that it is rotatably supported on the medicine container portion 10.

本発明の薬剤カセッターでは、係止具本体22は、付勢体25によって、その係止部23が薬剤整列路16に嵌入する方向に付勢されていることを特徴とする。 The drug Kasetta of the present invention, fastener body 22 by the urging Zeitai 25, characterized in that the locking portion 23 is biased in a direction to fit the drug alignment path 16.

本発明に係る薬剤カセッターは、カセッター本体の着脱、運搬時等に薬剤の排出を防止するための係止手段が、回転を阻止したい分配ローターの周壁を係止するものであるため、例えば、従属ギヤを係止する手段に比して、着脱時に確実に分配ローターを係止してその回転を阻止して薬剤を不用意に排出させないという効果を奏する。
さらに、薬剤排出位置にある薬剤整列路に係止手段たる係止部を嵌入する構成であれば、係止部によって薬剤の排出口を塞ぐことになるから、最も効果的に薬剤の不用意な排出を防止することができる。
In the medicine cassette according to the present invention, the locking means for preventing discharge of the medicine when the cassette body is attached / detached, transported, etc., locks the peripheral wall of the distribution rotor to be prevented from rotating. Compared with the means for locking the gear, there is an effect that the distribution rotor is securely locked at the time of attachment / detachment to prevent the rotation and prevent the medicine from being inadvertently discharged.
Furthermore, if the locking portion as the locking means is inserted into the drug alignment path at the drug discharge position, the drug discharge port is blocked by the locking portion, so that the drug is most effectively inadvertent. Emission can be prevented.

また、躯体1 には、永久磁石からなるキャッチ金具(図示せず)が設けられ、カセッター本体3 の周面10b の後方端部には、該キャッチ金具と対向する位置に磁石板(図示せず)が取付けられている。   The casing 1 is provided with catch metal fittings (not shown) made of permanent magnets, and a magnet plate (not shown) is disposed at the rear end of the peripheral surface 10b of the cassette body 3 at a position facing the catch metal fittings. ) Is installed.

上記構成からなる薬剤カセッターは、支持台2 から取外した際に、係止手段によって分配ローター11の周壁11a が係止されるので、カセッター本体3 の運搬時や薬剤の詰め替え時等のみならず、装着時に於いて不用意に分配ローター11が回転することはなく、従って、収容された薬剤が排出孔17から不用意に排出されることはない。   When the medicine cassette having the above structure is removed from the support base 2, the peripheral wall 11a of the distribution rotor 11 is locked by the locking means, so that not only when the cassette body 3 is transported or when the drug is refilled, The distribution rotor 11 does not rotate inadvertently at the time of mounting, and therefore the stored medicine is not inadvertently discharged from the discharge hole 17.

このように直接分配ローターを係止する係止手段であれば、例えば、従属ギヤを直接係止する手段のように、薬剤カセッターを取外した時に係止部材と従属ギヤの歯とが当接し、その後係止部材が従属ギヤの歯溝に嵌合することによって分配ローターが回転する虞れもなく、薬剤カセッターの着脱及び運搬時等に薬剤の排出を確実に防止することができることとなる。
これによって従属ギヤと分配ローターの薬剤整列路の数の関係によって不用意に薬剤を排出させる虞れも解消され、従って、薬剤カセッターの分配ローターのみを交換した場合であっても確実に薬剤の不用意な排出を防止できる。
If the locking means directly locks the distribution rotor in this way, for example, the locking member and the teeth of the dependent gear abut when the medicine cassette is removed, such as means for directly locking the dependent gear, After that, the engaging member is fitted into the tooth space of the subordinate gear so that the distribution rotor does not rotate, and the discharge of the medicine can be surely prevented when the medicine cassette is attached / detached and transported.
This eliminates the risk of inadvertent discharge of the drug due to the relationship between the number of subordinate gears and the number of drug alignment paths of the distribution rotor. Prepared discharge can be prevented.

また、係止手段は、その係止具本体22の係止部23が、凹状の薬剤整列路16に嵌入する構成であるため、係止部23と薬剤整列路16とは十分に係合し、更に、係止部23は、平面視三角形状に形成された突起からなるので、凹状の薬剤整列路16に嵌入し易い。
従って、例えば、装置停止時に分配ローター11が僅かに回転し過ぎていて薬剤排出位置B から僅かに位置ズレしている状態であっても、その突起の先端が位置ズレした薬剤整列路16に嵌入し、且つ突起の斜辺部23a が分配ローター11の周壁11a を構成する凸条面32の隅部32(図4参照)を押圧することとなるので、分配ローター11が僅かに戻されて係止部23が薬剤整列路16に嵌入し分配ローター11を係止することができるという利点がある。
Further, since the locking means has a configuration in which the locking portion 23 of the locking tool body 22 is fitted into the concave drug alignment path 16, the locking section 23 and the drug alignment path 16 are sufficiently engaged. Furthermore, since the locking portion 23 is made of a protrusion formed in a triangular shape in plan view, it is easy to fit into the concave medicine alignment path 16.
Therefore, for example, even when the distribution rotor 11 is slightly rotated when the apparatus is stopped and is slightly displaced from the medicine discharge position B, the tip of the protrusion is inserted into the medicine alignment path 16 where the position is displaced. In addition, since the oblique side portion 23a of the projection presses the corner portion 32 (see FIG. 4) of the convex surface 32 constituting the peripheral wall 11a of the distribution rotor 11, the distribution rotor 11 is slightly returned and locked. There is an advantage that the portion 23 can be fitted into the medicine alignment path 16 and the distribution rotor 11 can be locked.

さらに、薬剤排出位置B にある薬剤整列路16には、既に薬剤が排出されているので薬剤が存在することはなく空の状態であるから(勿論、仕切板18が設けられているカセッター本体3 にあっては、排出孔17から仕切板18までの間の薬剤整列路16を意味する)、カセッター本体3 を取り外すと係止具本体22の係止部23が、薬剤に邪魔されることもなく確実に薬剤整列路16に嵌入して分配ローター11を係止することができる。
加えて、薬剤排出位置B は、薬剤整列路16が排出孔17に連通する位置で、カセッター本体3 から支持台2 へ薬剤が排出される出口の部分であるから、その部分に係止部23を嵌入することは薬剤の出口を直接塞ぐことになるので、薬剤を排出させない手段として非常に効果的である。
Further, since the medicine is already discharged in the medicine alignment path 16 at the medicine discharge position B, the medicine does not exist and is empty (of course, the cassette main body 3 provided with the partition plate 18). In this case, it means the medicine alignment path 16 between the discharge hole 17 and the partition plate 18). When the cassette body 3 is removed, the locking portion 23 of the locking tool body 22 may be disturbed by the medicine. The dispensing rotor 11 can be locked by securely fitting into the medicine alignment path 16 without any problem.
In addition, the medicine discharge position B is a position where the medicine alignment path 16 communicates with the discharge hole 17 and is an exit portion from which the medicine is discharged from the cassette body 3 to the support base 2. Inserting the plug directly closes the outlet of the drug, so it is very effective as a means for preventing the drug from being discharged.

また、かかる係止手段が具備されたカセッター本体3 と上記構成からなる支持台2 とからなる薬剤分配装置は、カセッター本体3 を支持台2 に装着した時に、仮に、カセッター本体3 の従属ギヤ14の歯と支持台2 の主動ギヤ8 との歯とが当接した場合であっても、主動ギヤ8 はY方向(支持台2 の前方から後方向)に回転自在であるため、主動ギヤ8 が自転して歯同士の干渉を解消することととなるから、従属ギヤ14が回転することなく主動ギヤ8 と従属ギヤ14とは噛合することとなる。   In addition, the medicine dispensing device comprising the cassette main body 3 provided with such a locking means and the support base 2 having the above-described configuration is assumed to have a dependent gear 14 of the cassette main body 3 when the cassette main body 3 is mounted on the support base 2. Even when the teeth of the support base 2 and the teeth of the main drive gear 8 of the support base 2 come into contact with each other, the main drive gear 8 is rotatable in the Y direction (from the front to the rear of the support base 2). Will rotate and the interference between the teeth will be eliminated, so that the main gear 8 and the subordinate gear 14 will mesh without the subordinate gear 14 rotating.

即ち、主動ギヤ8 は従属ギヤ14の挿入方向(支持台2 の前方から後方向)に対して左側(一方側)に位置ズレして設けられ、且つ主動ギヤ8 は右側(他方側)がY方向に相対回転自在に駆動軸7 に連結されているので、主動ギヤ8 と従属ギヤ14とが接触した際には、主動ギヤ8 のみが回転することとなる。
従って、カセッター本体3 を支持台2 に装着した時に、ギヤ同士の噛み合わせの不備(歯同士の干渉)が生じず、更には、従属ギヤ14は回転しないので、装着時に分配ローター11が回転しないので薬剤を不用意に排出させることはない。
That is, the main driving gear 8 is provided on the left side (one side) with respect to the insertion direction of the subordinate gear 14 (from the front to the rear side of the support base 2), and the main driving gear 8 has the right side (the other side) Y. Since it is coupled to the drive shaft 7 so as to be relatively rotatable in the direction, only the main driving gear 8 rotates when the main driving gear 8 and the subordinate gear 14 come into contact with each other.
Therefore, when the cassette body 3 is mounted on the support base 2, incomplete meshing of gears (interference between teeth) does not occur, and furthermore, the subordinate gear 14 does not rotate, so the distribution rotor 11 does not rotate during mounting. So the drug is not inadvertently discharged.

尚、上記実施形態の薬剤カセッターは、上記構成から上述の利点を有してなるが、薬剤カセッターに設けられた係止手段は、分配ローター11の薬剤整列路16に嵌入脱可能な係止具本体22に限定されず、例えば、分配ローター11の周壁11a を構成する凸条面32を押圧することにより分配ローター11を係止する構成でもよく、又、該凸条面32に窪みを設け、該窪みに係止具本体22の係止部23が嵌入脱しうる構成であってもよい。
また、係止具本体22は、必ずしも薬剤排出位置B にて薬剤整列路16を係止する構成に限定されるものではない。
要は、カセッター本体3 を支持台2 から取外した際に分配ローター11の周壁11a を係止し、且つカセッター本体3 を支持台2 に装着した際に前記分配ローター11の係止を解除する係止手段であればその具体的な構成は問わない。
The drug cassette according to the above embodiment has the above-described advantages from the above-described configuration, but the locking means provided on the drug cassette is a locking tool that can be inserted into and removed from the drug alignment path 16 of the distribution rotor 11. It is not limited to the main body 22, for example, it may be configured to lock the distribution rotor 11 by pressing the convex surface 32 constituting the peripheral wall 11a of the distribution rotor 11, and the concave surface 32 is provided with a depression, A configuration in which the locking portion 23 of the locking tool main body 22 can be inserted into and removed from the recess may be employed.
Further, the locking tool main body 22 is not necessarily limited to the configuration for locking the drug alignment path 16 at the drug discharge position B 1.
The point is that the peripheral wall 11a of the distribution rotor 11 is locked when the cassette body 3 is removed from the support base 2, and the lock of the distribution rotor 11 is released when the cassette body 3 is mounted on the support base 2. If it is a stop means, the specific structure will not ask | require.

さらに、上記実施形態に於いて、係止部23は、平面視略三角形状に形成された突起からなり、薬剤整列路16が薬剤排出位置B から僅かに位置ズレしている状態でも、係止部23の斜辺部23a が分配ローター11の周壁11a を押圧することにより分配ローター11は斜辺部23a の傾斜辺によって僅かに戻されることになるので、空になった薬剤整列路16に係止部23が確実に嵌入し、且つ分配ローター11を係止するという利点があるが、係止部23は、平面視略三角形状の突起に限定されるわけではない。係止部23に、分配ローター11の凸条面32の隅部32a に当接する少なくとも一つの傾斜面23a が形成されていれば、上記利点を奏するからである。   Further, in the above-described embodiment, the locking portion 23 includes a protrusion formed in a substantially triangular shape in plan view, and the locking portion 23 is locked even when the drug alignment path 16 is slightly displaced from the drug discharge position B. When the oblique side 23a of the portion 23 presses the peripheral wall 11a of the distribution rotor 11, the distribution rotor 11 is slightly returned by the inclined side of the oblique side 23a. Although there is an advantage that 23 is securely inserted and the distribution rotor 11 is locked, the locking portion 23 is not limited to a substantially triangular protrusion in plan view. This is because the above-described advantages can be obtained if the locking portion 23 is formed with at least one inclined surface 23a that contacts the corner portion 32a of the convex surface 32 of the distribution rotor 11.

さらに、分配ローター11は、薬剤整列路16が形成された周壁11a と、薬剤を撹拌する撹拌傾斜部33(図5参照)とが一体的に形成されているが、夫々別体で形成されて別々に回転自在な構成であってもよい。   Furthermore, the distribution rotor 11 is integrally formed with the peripheral wall 11a in which the medicine alignment path 16 is formed and the stirring inclined portion 33 (see FIG. 5) for stirring the medicine, but each is formed separately. The structure which can be rotated separately may be sufficient.

また、上記実施形態の薬剤分配装置は、上記構成から上述の利点を有してなるが、駆動手段の一方向の回転を分配ローター11に伝達し、反対方向の回転を分配ローター11に伝達させない手段として、駆動手段の駆動軸7 に主動ギヤ8 を一方向のみに相対回転自在に連結したものを例示したが、例えば、駆動軸7 と主動ギヤ8 とは回転不能に連結され、且つ従属ギヤ14と分配ローター11とが一方向のみに回転可能な構成であっても上述の作用効果を奏する。
勿論両ギヤが一方向に回転可能に連結されていてもよく、又、他のギヤを介在させて何れかのギヤが一方向に回転可能な構成であってもよい。
Further, the medicine dispensing device of the above embodiment has the above-mentioned advantages from the above configuration, but transmits the rotation in one direction of the driving means to the distribution rotor 11, and does not transmit the rotation in the opposite direction to the distribution rotor 11. As the means, the main drive gear 8 is connected to the drive shaft 7 of the drive means so as to be relatively rotatable in only one direction. For example, the drive shaft 7 and the main drive gear 8 are non-rotatably connected and the subordinate gears. Even if 14 and the distribution rotor 11 are configured to be rotatable only in one direction, the above-described effects can be obtained.
Of course, both gears may be coupled so as to be rotatable in one direction, or any gear may be configured to be rotatable in one direction with another gear interposed.

要は、薬剤カセッターを着脱時に、主動ギヤ8 又は/及び従属ギヤ14が何れかの方向に自転して、両ギヤが嵌入又は離脱せずに互いに干渉することを防止でき、且つ薬剤分配装置を作動させる際には、主動ギヤ8 が従属ギヤ14に駆動装置の一方向の回転を伝達して分配ローター11を回転させて薬剤を排出するという本来の機能に支障を来さない構成であれば、その意図する範囲内で自由に設計変更可能である。   In short, when the medicine cassette is attached / detached, the main driving gear 8 and / or the subordinate gear 14 can rotate in either direction to prevent both gears from interfering with each other without being inserted or removed, and the medicine dispensing device can be When operating, if the main drive gear 8 transmits the rotation of the drive device in one direction to the slave gear 14 and rotates the distribution rotor 11 to discharge the medicine, it does not interfere with the original function. The design can be freely changed within the intended range.
