It is guided between the support rollers 12-3 and 12-4 (FIG. 20 (f)). If the connecting plate 7 is inserted until the distance between the supporting rollers 12-1 and 12-2 and the distance between the supporting rollers 12-3 and 12-4 coincides with the width of the connecting plate 7 at that position, Since it can no longer be inserted, the movement of the bed 3 stops. This position is the docking position shown in FIG.
- the bed 3 is held by the roller unit 50 of the apparatus body 2 by the connecting plate 7 narrower than the bellows portion 35 in the short axis direction of the bed 3.

For this reason, the force for holding the bed 3 in the left-right direction is reduced, while the force for pushing the bed 3 from the apparatus main body 2 is increased. Therefore, in the present embodiment, it is desirable that the four rollers 9 be arranged so as to be in contact with the straight portion of the connecting plate 7.
- the connecting plate 7 has a substantially trapezoidal shape and the straight portion 51 is inclined, when the bed 3 is attached to and detached from the apparatus main body 2, the apparatus is viewed from an oblique direction as shown in FIG. It can be inserted into the docking unit 5 of the main body 2 or can be detached obliquely.

If the electromagnetic shield room where the device main body 2 is arranged is sufficiently wide and the bed 3 can be lowered straight until the connecting plate 7 is detached from the roller unit 50, the connecting plate 7 can be made substantially rectangular. It is. In this case, since the component force R1x to R4x of the roller reaction force R1 to R4 in the longitudinal direction x of the bed does not occur, it can be used to balance all the roller reaction force with the external force in the left and right direction applied to the bed 3. Can be improved. Further, the tension of the wire 111 can be reduced.

- the lock bar 115 reaches the cutout region 108b having the radius r2 ( ⁇ r1) of the lock plate A108, so that the lock bar 115 comes into contact with the arc region 109a of the lock plate B109 having the same radius r2. . Therefore, the lock plate B1 can be locked by the lock bar 115.
- the lock bar 15 cannot get back over the flank side shape of the convex portion 144, and the lock plate B109 is locked by the lock bar 115 as shown in FIG. 606). Since the radius of the lock region 109b of the lock plate 109 is r2 and is equal to the radius r2 of the region where the lock bar 115 of the lock plate A108 in the locked state is in contact, the lock bar 115 is in contact with the lock plates A108 and B109 at the same time. Is locked (step 607). When the wire B112 is pulled along with the rotation of the lock plate B109, the coupling tool 221 rotates and pulls the pin 22 as shown in FIG. 33 (b).
- step 608 the electrical connector 224 of the docking unit 4 on the bed 3 side and the electrical connector 223 of the docking unit 5 on the bed body 2 side are fitted, and the electrical docking is completed (step 608).
- the hook 8 since the hook 8 has already been connected to the connecting bar 10 in step 603, the docking units 4 and 5 are connected mechanically and electrically.
- the lock plate B109 does not come into contact with the lock bar 115, and the pedal can be easily depressed with a small force.
- the electrical docking pedal 106 is depressed in the unlocked state before the mechanical docking pedal 105 is operated, the electrical docking pedal 106 is not locked and cannot be electrically docked. The difference allows the operator to notice that the procedure is incorrect.
- step 611 when the release pedal 107 is depressed as shown in FIG. 35, the wire C116 is pulled by the release plate 117, and the connector 221 is pulled in the release direction (step 701). At the same time, the lock bar 115 is gradually pushed up by the inclined surface of the tip of the release plate 117. Thus, when the height of the lock bar 115 reaches the radius r5 of the convex portion 114 of the lock plate B109, the lock of the lock plate B109 is first released as shown in FIG. 35 (step 702).
- step 703 the force with which the lock plate B109 pulls the wire B112 is released, and the force with which the wire C116 pulls the connecting tool 221 in the releasing direction is added, and the connecting tool 221 rotates backward as shown in FIG.
- step 703 the electrical docking is released.
- the hook 8 remains connected to the connecting bar 10 as shown in FIG.
- step 704 When the inspector further depresses the release pedal 7 deeply as shown in FIG. 37 (step 704), the release plate 117 further pushes up the lock bar 115, and the height of the lock bar 115 becomes higher than the tip of the convex portion 143 of the lock plate A.
- step 705 the lock plate A108 is unlocked as shown in FIG. 37 (step 705).
- the force with which the lock plate A108 pulls the wire A111 is released, and the hook 8 is lifted by the force of the spring 48 arranged in the docking unit 4 as shown in FIG. 706).
- the hook 8 is detached from the connecting bar 10 and the mechanical docking is released.
- step 703 as shown in FIG. 38 (b), since the electrical connectors 223 and 224 have already been disconnected in step 703, both mechanical docking and electrical docking are released.
- the release pedal 107 When the inspector removes his / her foot from the release pedal 107, the release pedal 107 is returned to the initial state (FIG. 24) by the pedal return spring 135 (steps 707 to 709), and the operation is completed.
- the pedal unit 104 of the present invention is not locked unless it is operated in a predetermined order, and can prevent an erroneous procedure operation.
- the pedal can be depressed with a small force and the operation feeling cannot be obtained, so that the operator can notice this when there is an error in the operation procedure. .
- this pedal unit for connecting the bed and the apparatus body, mechanical docking and electrical docking can always be performed in this order, and damage to the electrical connector can be prevented. Further, when releasing, the electrical docking release and the mechanical docking release can be performed in this order, and the phenomenon that the bed moves while the electrical connector is fitted and the connector is damaged can be prevented.
- the pedal unit of the present invention returns to the initial position when the foot is released from the pedal, so that it is possible to prevent an accident such that the pedal unexpectedly returns to the initial position when it is released and hits the operator's foot.
- the present invention is not limited to the shape of FIG. 24, and the shape can be arbitrarily changed.
- the lock plates 108 and 109 can be doubled to improve the strength.
- the lock bar 115 may be supported by the support portions 145 at both ends and in the center.
- two pedals 105 and 106 for docking are provided and the mechanism is locked in two stages with two plates having different sizes.
- three or more pedals for docking are provided, It is also possible to provide a mechanism that locks in more stages. In this case, three lock plates with different radii are used.

Abstract
Description
医用画像撮像装置1は、図1に示すように装置本体2と寝台3とを備えている。装置本体2は、寝台3に搭載された被検体の画像を撮像する構成であればどのような構成であってもよい。例えば、MRI装置やCT装置の本体を用いることができる。ここでは、医用画像撮像装置1が、MRI装置である場合を例に以下説明する。
ドッキングユニット4,5の構造を図3等を用いて具体的に説明する。
図3は、図2のドッキングユニット4,5からカバー37,53を外した状態の寝台2の斜視図と、ドッキングユニット5の斜視図である(装置本体2は省略している)。図4、図5は、カバー37,53を外したドッキングユニット4,5の斜視図である。図6は、ドッキングユニット4からカバー37と電気コネクタ224とその駆動機構を取り外した状態の斜視図である。図7は、ドッキングユニット5に連結した寝台3のE-E断面図である(カバー37,53を外し、連結プレート7とローラ9のみを示している)。図8において、(a)は、カバー37を外したドッキングユニット4の上面図、(b)は、カバー37を外したドッキングユニット4のA-A断面図、(c)は、カバー53を外したドッキングユニット5の上面図、(d)は、カバー53を外したドッキングユニット5のB-B断面図である。ただし、図8では、連結プレート7、フック8、ローラユニット50は省略されている。図9において、(a)はカバー37を外したドッキングユニット4の側面図、(b)は、カバー37を外したドッキングユニット4のC-C断面図、(c)は、カバー53を外したドッキングユニット5の側面図、(d)は、カバー53を外したドッキングユニット5のD-D断面図である。
第1の実施形態では、電気コネクタ223をスライド外枠262に対して左右上下および前後に可動にするために、スライドプレート271,272を用いたが、本発明はこれに限られるものではない。第2の実施形態では、図13のようにスライドプレート271,272に代えて、ボールジョイント301を用いる。ボールジョイントは、ボール301aとこれを回転可能に支持する支持部301bとを含み、ボール301aを電気コネクタ223またはコネクタ支持枠270に固定する。支持部301bをばね273,274,275で支持する。
第1の実施形態では、装置本体2側の電気コネクタ223がスライド外枠262をスライド可能な構成とし、電気コネクタ224側は固定されていたが、本発明はこの構成に限られるものではない。第3の実施形態では、電気コネクタ224の背面に、図14のように複数のアーム351,352,353が順に連結したリンク機構を配置し、リンク機構の動作により電気コネクタ224を電気コネクタ223に向かって押しだして連結する構成にする。
ここで、上述の第1~第3の実施形態のドッキングユニット4,5内に配置される連結プレート7およびローラユニット50の構成についてさらに詳しく説明する。
ローラ9と滑り軸受81が一体となって、軸82の周囲を回転する。軸82およびローラ9は剛性の大きな金属製であり、滑り軸受81も剛性が大きく滑りのよい材料で構成されている。これにより、連結プレート7がローラユニット50に挿入され、ローラ9に接触しながら進んでも、ローラ9は変形したり、撓んだりすることはなく、挿入された連結プレート7をローラ9間に挟みこんで保持することができる。
これにより、装置本体2が配置されている電磁シールド室が狭くても、寝台3を着脱することが可能になる。
上述の第1~第3の実施形態の寝台3内に配置されるペダル105~107を備えたペダルユニットの構成についてさらに詳しく説明する。
連結具221は、ワイヤ112に引っ張られて、回転軸250を中心に回転することにより、電気コネクタ223と224とを結合する。一方、ワイヤ116が引っ張られて連結具221が逆方向に回転することにより、連結を解除する。
また、フック8および連結具221を簡略化して示すと、図28(a),(b)の状態であり、連結バー10およびピン222とは係合していない。
