前記配線ダクトの一態様は、前記補助配線保持部は、前記配線を保持する保持本体部と、この保持本体部の両縁に立設される一対の側壁部とを有する。   In one aspect of the wiring duct, the auxiliary wiring holding portion includes a holding main body portion that holds the wiring, and a pair of side wall portions that are erected on both edges of the holding main body portion.

前記配線ダクトの一態様は、前記一対の側壁部のいずれかには、前記保持本体部に保持された配線を保護する覆い部が着脱自在に備えられる。   In one aspect of the wiring duct, a cover portion that protects the wiring held by the holding main body portion is detachably provided on one of the pair of side wall portions.

前記配線ダクトの一態様は、前記一方の筐体の枠体には、前記一対の筐体が分離状態の際に前記保持本体部を水平に保持する一方で当該一対の筐体が会合及び分離する過程での当該枠体からの当該保持本体部の一端縁の引き出しを抑制するように当該一端縁を吊り下げ支持する吊り下げ部材が連結されている。   In one aspect of the wiring duct, the frame of the one casing holds the holding main body portion horizontally when the pair of casings are in a separated state, while the pair of casings meet and separate. A suspension member that suspends and supports the one end edge of the holding main body portion from the frame body during the process is supported so as to prevent the one end edge from being pulled out.

以上の本発明によれば、筐体内に配線が大掛かりに導入されても、筐体の設置状態の安定性が確保され、筐体の構造補強を要することなく、配線を収容させる筐体の製造コストの削減を図ることができる。   According to the present invention as described above, even when wiring is introduced into the housing in a large scale, the stability of the installation state of the housing is ensured, and the manufacturing of the housing that accommodates the wiring without requiring structural reinforcement of the housing.

（筐体分離機構１の動作例）
図１〜３，９，１０を参照して本実施形態の筐体分離機構１の動作例について説明する。 (Operation example of the housing separation mechanism 1)
An example of the operation of the housing separation mechanism 1 of the present embodiment will be described with reference to FIGS.

先ず、筐体２ａと筐体２ｂを分離させる際の筐体分離機構１の動作例について説明する。   First, an operation example of the housing separation mechanism 1 when separating the housing 2a and the housing 2b will be described.

筐体２ａと筐体２ｂとが会合状態である場合、図９（ａ），図１０（ａ）に示されたように、レール部１２はレール部１１に収容されると共にレール部１３はレール部１２に収容された状態となっている。ここで、図１の筐体２ｂの底部正面カバー２４が取り外されると、図３に示された底部枠体２１ｂの正面下端部から回転軸１４，回転軸１５の工具受け部１６，１７が露出する。   When the housing 2a and the housing 2b are in a meeting state, as shown in FIGS. 9A and 10A, the rail portion 12 is accommodated in the rail portion 11 and the rail portion 13 is a rail. It is in a state of being accommodated in the section 12. Here, when the bottom front cover 24 of the housing 2b of FIG. 1 is removed, the tool receivers 16 and 17 of the rotary shaft 14 and the rotary shaft 15 are exposed from the front lower end of the bottom frame 21b shown in FIG. To do.

次いで、図９（ａ）に示された回転軸１４の工具受け部１６に前記工具の回転軸の先端部を嵌合させて当該回転軸を反時計回り方向に回転させると、支持部４１からその正面側に回転軸１４が送り出される。このとき、図９（ｂ）に示したように、レール部１２がレール部１１の正面側端部から延出すると共に、上部枠体２２ａ，２２ｂにおいてはレール部１１の一端からレール部１２が延出し、これに伴い、底部枠体２１ｂの車輪２３が筐体２の前方に床面を転動する。そして、回転軸１４の一端部のストッパーが支持部４１と当接すると、前記延出の分だけ筐体２の前方向に筐体２ｂが離れた状態となる。   Next, when the tip of the rotary shaft of the tool is fitted to the tool receiving portion 16 of the rotary shaft 14 shown in FIG. 9A and the rotary shaft is rotated in the counterclockwise direction, the support portion 41 takes off. The rotating shaft 14 is sent out to the front side. At this time, as shown in FIG. 9B, the rail portion 12 extends from the front side end portion of the rail portion 11, and the rail portion 12 extends from one end of the rail portion 11 in the upper frame bodies 22a and 22b. As a result, the wheel 23 of the bottom frame 21 b rolls on the floor surface in front of the housing 2. And if the stopper of the one end part of the rotating shaft 14 contact | abuts to the support part 41, it will be in the state which the housing | casing 2b left | separated to the front direction of the housing | casing 2 only by the said extension.

次いで、筐体２ａと筐体２ｂとの間にスペースをさらに確保したい場合、回転軸１５の工具受け部１７に前記工具の回転軸の先端部を嵌合させて当該回転軸を反時計回り方向に回転させると、支持部４２からその正面側に回転軸１５が送り出される。このとき、図９（ｃ），図１０（ｂ）（ｃ）に示したように、レール部１３がレール部１２の正面側端部から延出し、上部枠体２２ａ，２２ｂにおいてはレール部１２の一端からレール部１３が延出し、これに伴い、底部枠体２１ｂの車輪２３が筐体２の前方に床面を転動する。そして、この回転軸１５の背面側端部のストッパーが支持部４２と当接すると、前記延出の分だけ筐体２ａと筐体２ｂとがさらに離間した状態となる。   Subsequently, when it is desired to further secure a space between the housing 2a and the housing 2b, the tip of the rotary shaft of the tool is fitted into the tool receiving portion 17 of the rotary shaft 15 so that the rotary shaft is rotated in the counterclockwise direction. , The rotating shaft 15 is sent out from the support portion 42 to the front side thereof. At this time, as shown in FIG. 9C, FIG. 10B, and FIG. 10C, the rail portion 13 extends from the front end portion of the rail portion 12, and the rail portion 12 is formed in the upper frames 22a and 22b. The rail portion 13 extends from one end of the rail, and accordingly, the wheel 23 of the bottom frame body 21 b rolls on the floor surface in front of the housing 2. When the stopper at the rear side end of the rotating shaft 15 comes into contact with the support portion 42, the housing 2a and the housing 2b are further separated from each other by the extension.

以上のように筐体２ａと筐体２ｂとが分離した状態となり図１に示したように筐体２ａと筐体２ｂとの間にメンテナンススペースが確保される。その後、例えば、筐体２ａ内に電子部品として端子台が格納される一方で筐体２ｂ内に図示省略の電子機器が格納される。そして、筐体２ａと筐体２ｂとの間に介入した作業員による配線作業によって前記端子台と前記電子機器とが電気的に接続される。   As described above, the casing 2a and the casing 2b are separated from each other, and a maintenance space is secured between the casing 2a and the casing 2b as shown in FIG. Thereafter, for example, a terminal block is stored as an electronic component in the housing 2a, while an electronic device (not shown) is stored in the housing 2b. And the said terminal block and the said electronic device are electrically connected by the wiring operation | work by the worker who intervened between the housing | casing 2a and the housing | casing 2b.

次に、筐体２ａと筐体２ｂを会合させる際の筐体分離機構１の動作例について説明する。   Next, an operation example of the housing separation mechanism 1 when the housing 2a and the housing 2b are brought together will be described.

前記配線作業が完了すると筐体２ａと筐体２ｂと会合操作が行われる。すなわち、図９（ｃ），図１０（ｂ）（ｃ）に示された回転軸１５の工具受け部１７に前記工具の回転軸の先端部を嵌合させて当該回転軸を時計回り方向に回転させると、回転軸１５が支持部４２の背面側に送り込まれる。このとき、レール部１３がレール部１２内に送り込まれ、上部枠体２２ａ，２２ｂにおいてもレール部１３がレール部１２に送り込まれ、これに伴い、底部枠体２１ｂの車輪２３が筐体２の後方に床面を転動する。そして、この回転軸１５の他端部のストッパーが支持部４２と当接すると、図９（ｂ）に示したようにレール部１３がレール部１２に収容され、この収容の分だけ筐体２ａと筐体２ｂとの間隔が縮小した状態となる。   When the wiring work is completed, a meeting operation is performed between the housing 2a and the housing 2b. That is, the tip of the rotary shaft of the tool is fitted to the tool receiving portion 17 of the rotary shaft 15 shown in FIGS. 9C, 10B and 10C, and the rotary shaft is rotated in the clockwise direction. When rotated, the rotating shaft 15 is fed to the back side of the support portion 42. At this time, the rail portion 13 is fed into the rail portion 12, and the rail portion 13 is also fed into the rail portion 12 in the upper frame bodies 22 a and 22 b, and accordingly, the wheels 23 of the bottom frame body 21 b are moved to the housing 2. Roll the floor backwards. Then, when the stopper at the other end of the rotating shaft 15 comes into contact with the support portion 42, the rail portion 13 is accommodated in the rail portion 12 as shown in FIG. And the space between the housing 2b are reduced.

そして、回転軸１４の工具受け部１６に前記工具の回転軸の先端部を嵌合させて当該回転軸を時計回り方向に回転させると、回転軸１４が支持部４１の背面側に送り込まれる。このとき、レール部１２がレール部１１内に送り込まれ、上部枠体２２ａ，２２ｂにおいてもレール部１２がレール部１１に送り込まれ、これに伴い、底部枠体２１ｂの車輪２３が筐体２の後方に床面を転動する。そして、回転軸１４の一端部のストッパーが支持部４１と当接すると、図９，１０に示したようにレール部１２がレール部１１に収容され、このとき、筐体２ａと筐体２ｂとが会合した状態となる。   And if the front-end | tip part of the rotating shaft of the said tool is fitted to the tool receiving part 16 of the rotating shaft 14, and the said rotating shaft is rotated clockwise, the rotating shaft 14 will be sent to the back side of the support part 41. FIG. At this time, the rail portion 12 is fed into the rail portion 11, and the rail portion 12 is also fed into the rail portion 11 in the upper frame bodies 22 a and 22 b, and accordingly, the wheels 23 of the bottom frame body 21 b are moved to the housing 2. Roll the floor backwards. When the stopper at one end of the rotating shaft 14 comes into contact with the support portion 41, the rail portion 12 is accommodated in the rail portion 11 as shown in FIGS. 9 and 10, and at this time, the housing 2a and the housing 2b Are in a meeting.

（作業台６の動作例）
図１〜８を参照しながら作業台６の動作例について説明する。 (Operation example of work table 6)
An example of the operation of the work table 6 will be described with reference to FIGS.

先ず、筐体２ａと筐体２ｂの分離過程での作業台６の動作例について説明する。   First, an example of the operation of the work table 6 in the process of separating the housing 2a and the housing 2b will be described.

図２に示したように筐体２ａと筐体２ｂとが会合状態である場合、作業台６は図８に示したように筐体２ａに収容された状態となっている。そして、筐体分離機構１の操作により、筐体２ａから筐体２ｂが離される過程で、筐体２ａの枠体２０ａ内の第四の支持部６４の鉛直面６４０の上端付近に位置する作業台６の第一の車輪６５ａは鉛直面６４０を徐々に下降する。一方、第一の支持部６１の下端側の第三の支持部６３の一端は枠体２０ａから引き出される。この第一の車輪６５ａの下降に伴い、枠体２０ａ内を作業台６の第一の支持部６１の一端は下降する。次いで、筐体分離機構１の操作により、筐体２ｂが筐体２ａからさらに離される過程で、第一の支持部６１の一端がさらに下降し、図７に示したように、作業台６の第二の車輪６５ｂが鉛直面６４０に到達すると、第一の車輪６５ａが鉛直面６４０から離れた状態となる。さらに、筐体分離機構１の操作により、筐体２ｂが筐体２ａから離され、これに伴い、第一の支持部６１の一端がさらに下降すると、第二の車輪６５ｂは案内部６６に導かれてさらに下降する。そして、第一の車輪６５ａが底部枠体２１ａ上の第二の支持部６２に到達すると、図１，６に示したように作業台６の作業台本体部６０は筐体２ａと筐体２ｂの間に水平に敷設された状態となる。   When the housing 2a and the housing 2b are in a meeting state as shown in FIG. 2, the work table 6 is in a state of being accommodated in the housing 2a as shown in FIG. Then, in the process of separating the housing 2b from the housing 2a by the operation of the housing separation mechanism 1, an operation located near the upper end of the vertical surface 640 of the fourth support portion 64 in the frame 20a of the housing 2a. The first wheel 65a of the base 6 gradually descends the vertical surface 640. On the other hand, one end of the third support portion 63 on the lower end side of the first support portion 61 is pulled out from the frame body 20a. As the first wheel 65a descends, one end of the first support portion 61 of the work table 6 descends in the frame 20a. Next, in the process in which the housing 2b is further separated from the housing 2a by the operation of the housing separating mechanism 1, one end of the first support portion 61 is further lowered, and as shown in FIG. When the second wheel 65b reaches the vertical surface 640, the first wheel 65a is separated from the vertical surface 640. Further, when the casing separation mechanism 1 is operated, the casing 2b is separated from the casing 2a, and when one end of the first support portion 61 is further lowered, the second wheel 65b is guided to the guide portion 66. Then it goes down further. When the first wheel 65a reaches the second support portion 62 on the bottom frame 21a, the worktable main body 60 of the worktable 6 has the housing 2a and the housing 2b as shown in FIGS. It will be in the state laid horizontally between.

次に、筐体２ａと筐体２ｂの会合過程での作業台６の動作例について説明する。   Next, an example of the operation of the work table 6 during the meeting process of the housing 2a and the housing 2b will be described.

筐体分離機構１の操作により、筐体２ｂが筐体２ａに近づく過程で、図６に示された作業台６の第一の車輪６５ａは第二の支持部６２の上面を案内部６６に向かって移動する。さらに、筐体２ｂが筐体２ａに近づくにつれて、作業台６の第一の支持部６１の一端がさらに枠体２０ａ内に導入され、先ず、図７に示したように、第二の車輪６５ｂが案内部６６に導かれて枠体２０ａ内を上昇する。次いで、筐体分離機構１の操作により、筐体２ｂがさらに筐体２ａに近づく過程で、第一の支持部６１の一端が枠体２０ａ内でさらに上昇し、第一の車輪６５ａが案内部６６に導かれて枠体２０ａ内を上昇する。やがて、図８に示したように、第一の車輪６５ａが第四の支持部６４の鉛直面６４０に到達すると、第二の車輪６５ｂが鉛直面６４０から離れた状態となる。次いで、筐体分離機構１の操作により、筐体２ｂがさらに筐体２ａに近づく過程で、第一の車輪６５ａは鉛直面６４０を上昇する。この第一の車輪６５ａの上昇に伴い、作業台６の第一の支持部６１の一端は枠体２０ａ内をさらに上昇する。そして、図２，８に示したように筐体２ａと筐体２ｂとが会合すると、作業台６は、第一の支持部６１の一端が枠体２０ａ内における第四の支持部４の上端付近の鉛直面６４０に第一の車輪６５ａにより支持された状態で筐体２ｂ内に収容されたものとなる。   In the process in which the housing 2b approaches the housing 2a by the operation of the housing separating mechanism 1, the first wheel 65a of the work table 6 shown in FIG. Move towards. Further, as the housing 2b approaches the housing 2a, one end of the first support portion 61 of the work table 6 is further introduced into the frame 20a. First, as shown in FIG. Is guided to the guide portion 66 and moves up in the frame 20a. Next, in the process in which the housing 2b further approaches the housing 2a by the operation of the housing separating mechanism 1, one end of the first support portion 61 is further raised in the frame 20a, and the first wheel 65a is moved to the guide portion. It is guided to 66 and rises in the frame 20a. Eventually, as shown in FIG. 8, when the first wheel 65 a reaches the vertical surface 640 of the fourth support portion 64, the second wheel 65 b is separated from the vertical surface 640. Next, the first wheel 65a ascends the vertical surface 640 in the process in which the housing 2b further approaches the housing 2a by the operation of the housing separation mechanism 1. As the first wheel 65a rises, one end of the first support portion 61 of the work table 6 further rises in the frame 20a. 2 and 8, when the casing 2a and the casing 2b meet, one end of the first support 61 is the upper end of the fourth support 4 within the frame 20a. It is accommodated in the housing 2b in a state of being supported on the nearby vertical surface 640 by the first wheel 65a.

（配線ダクト７の動作例）

It is accommodated in the housing 2a in a folded state as if facing each other.

先ず、筐体分離機構１の操作により、枠体２０ａ内の作業台６の第一の車輪６５ａを下降させて底部枠体２１ａ上の第二の支持部６２に到達させると、図８の状態から図７の状態を経て図６に示した筐体２ａと筐体２ｂとが分離した状態となる。このとき、配線ダクト７の配線保持部７１は、図６に示されたように、筐体２ａと筐体２ｂの間に位置する作業台６の下で略水平に配置された状態となる。また、配線保持部７１の一端縁に連結された補助配線保持部７２は、枠体２０ａに連結された一対の吊り下げ部材９により作業台６の下で略水平に配置された状態となる。   First, when the first wheel 65a of the work table 6 in the frame 20a is lowered by the operation of the housing separation mechanism 1 to reach the second support portion 62 on the bottom frame 21a, the state of FIG. Then, the housing 2a and the housing 2b shown in FIG. 6 are separated from each other through the state of FIG. At this time, as shown in FIG. 6, the wiring holding portion 71 of the wiring duct 7 is in a state of being arranged substantially horizontally under the work table 6 located between the housing 2a and the housing 2b. Further, the auxiliary wiring holding portion 72 connected to one end edge of the wiring holding portion 71 is in a state of being disposed substantially horizontally under the work table 6 by the pair of hanging members 9 connected to the frame body 20a.

次いで、筐体２ａ，２ｂ内に外部から配線８が導入される。図６〜８に例示された態様の筐体２ａ，２ｂにおいては筐体２ａの枠体２０ａの下端部若しくは下端部付近背部の開口部から配線８が導入される。   Next, the wiring 8 is introduced into the housings 2a and 2b from the outside. In the cases 2a and 2b illustrated in FIGS. 6 to 8, the wiring 8 is introduced from the lower end of the frame 20a of the case 2a or the opening near the lower end.

次いで、例えば、図３に示したように作業台６の作業台本体部６０及び補助配線保持部７２の覆い部７３を起立させた状態で、図６に示されたように、配線８が、配線保持部７１及び補助配線保持部７２に並列配置された状態で、筐体２ｂ内の図示省略の電子機器に接続される。そして、図３，４に示された覆い部７３が固定具７３２により補助配線保持部７２の側壁部７２１に固定される。さらに、図６に示したように作業台６の作業台本体部６０が固定具６０２により第一の支持部６１に固定される。   Next, for example, as shown in FIG. 6, with the worktable main body 60 of the worktable 6 and the cover 73 of the auxiliary wiring holding part 72 erected as shown in FIG. In a state of being arranged in parallel with the wiring holding unit 71 and the auxiliary wiring holding unit 72, it is connected to an electronic device (not shown) in the housing 2b. The cover portion 73 shown in FIGS. 3 and 4 is fixed to the side wall portion 721 of the auxiliary wiring holding portion 72 by the fixture 732. Further, as shown in FIG. 6, the work table main body 60 of the work table 6 is fixed to the first support 61 by the fixture 602.

そして、筐体分離機構１の操作により、枠体２０ａ内の作業台６の第一の車輪６５ａが案内部６６を介して上昇して枠体２０ａ内の第四の支持部６４の上端付近に到達すると、図６の状態から図７の状態を経て図８に示された筐体２ａと筐体２ｂとが会合した状態となる。このとき、配線ダクト７は折り畳まれ、さらに、配線８の一部がこの配線ダクト７に収容された状態で筐体２ａ，２ｂに収納される。   Then, by the operation of the housing separation mechanism 1, the first wheel 65 a of the work table 6 in the frame body 20 a rises through the guide portion 66 and near the upper end of the fourth support portion 64 in the frame body 20 a. Upon arrival, the housing 2a and the housing 2b shown in FIG. 8 are brought into association with each other through the state shown in FIG. 6 and the state shown in FIG. At this time, the wiring duct 7 is folded, and further, a part of the wiring 8 is housed in the housings 2 a and 2 b in a state of being housed in the wiring duct 7.

（第一実施形態の効果）
以上の筐体２によれば、筐体分離機構１は、レール部１１の一端からレール部１２がレール移動機構によって延出可能となっている一方でレール部１２の一端からレール部１３がレール移動機構によって延出可能なっている。よって、筐体２ａと筐体２ｂとが分離可能となり、筐体２ａと筐体２ｂとの間にメンテナンススペースを確保できる。 (Effects of the first embodiment)
According to the housing 2 described above, the housing separating mechanism 1 is configured such that the rail portion 12 can be extended from one end of the rail portion 11 by the rail moving mechanism, while the rail portion 13 is connected to the rail from the one end of the rail portion 12. It can be extended by a moving mechanism. Therefore, the housing 2a and the housing 2b can be separated, and a maintenance space can be secured between the housing 2a and the housing 2b.

特に、他方の筐体２ｂの移動過程で任意の位置で筐体２ｂを静置させることが可能となり、筐体２ｂの移動中の安全性を確保させながらも、筐体２ａと筐体２ｂとの間に任意領域のスペースを確保できる。よって、筐体２ａ，２ｂ内に電子機器が大掛かりに搭載された場合であっても、電子機器のメンテナンス時に筐体２ｂを移動させる際の作業員の安全性を確保できる。   In particular, the housing 2b can be allowed to stand at an arbitrary position in the process of moving the other housing 2b, and the housing 2b and the housing 2b can be secured while ensuring safety during the movement of the housing 2b. A space in an arbitrary area can be secured between the two. Therefore, even when electronic devices are mounted on the housings 2a and 2b on a large scale, it is possible to ensure the safety of workers when the housing 2b is moved during maintenance of the electronic devices.

また、筐体２ａと筐体２ｂとが分離された際には、この筐体２ａと筐体２ｂとの間に作業台６が敷設された状態となるので、筐体２ａ，２ｂの内部メンテナンスを行う作業者が作業台を筐体２ａと筐体２ｂとの間に設置させる手間が省かれる。したがって、筐体２ａ，２ｂの内部メンテナンス時の安全性及び作業効率が向上する。   Further, when the casing 2a and the casing 2b are separated, the work table 6 is laid between the casing 2a and the casing 2b, so that internal maintenance of the casings 2a and 2b is performed. This saves the labor of the operator performing the installation of the work table between the housing 2a and the housing 2b. Therefore, safety and work efficiency at the time of internal maintenance of the housings 2a and 2b are improved.

さらに、作業台６の第一の支持部６１は、第二の支持部６２の上面を移動可能な第一の車輪６５ａを備えているので、筐体２ａ，２ｂ間に作業台６を配置させる際または作業台６を筐体２ａ，２ｂ内に収容させる際の筐体分離機構１の操作性が向上する。   Furthermore, since the first support portion 61 of the work table 6 includes the first wheel 65a that can move on the upper surface of the second support portion 62, the work table 6 is disposed between the housings 2a and 2b. In this case, the operability of the case separation mechanism 1 when the work table 6 is accommodated in the cases 2a and 2b is improved.

そして、枠体２０ａ内の第四の支持部６４には、筐体２ａ，２ｂが会合状態に至る過程で第一の車輪６５ａが鉛直に移動して当該会合状態の際に第一の車輪６５ａを介して第一の支持部の一端を支持する鉛直面６４０が確保されている。したがって、筐体２ａ，２ｂが会合状態の際に、作業台６を安定支持することができる。また、筐体２ａ，２ｂが分離させる際に、作業台６を効率的に枠体２０ａから引き出すことできる。   In the fourth support portion 64 in the frame 20a, the first wheel 65a moves vertically in the process in which the housings 2a and 2b reach the meeting state, and the first wheel 65a in the meeting state. A vertical surface 640 for supporting one end of the first support portion is secured through the. Therefore, the work table 6 can be stably supported when the housings 2a and 2b are in the meeting state. Further, when the casings 2a and 2b are separated, the work table 6 can be efficiently pulled out from the frame body 20a.

また、筐体２ａ，２ｂを会合させる過程または分離させる過程で枠体２０ａ内の第一の車輪６５ａは案内部６６により案内されるので筐体２ａ，２ｂにおいて作業台６を収納及び敷設させる際の作業性がさらに向上する。   Further, since the first wheel 65a in the frame 20a is guided by the guide portion 66 in the process of associating or separating the casings 2a and 2b, when the work table 6 is stored and laid in the casings 2a and 2b. Workability is further improved.

さらに、第一の支持部６１の先端側に具備された第二の車輪６５ｂは、筐体２ａ，２ｂが会合状態に至る過程で第一の車輪６５ａよりも先に案内部６６により第四の支持部６４に案内されるので、筐体２ａ，２ｂを会合させる際の作業員の負担が軽減される。   Further, the second wheel 65b provided on the distal end side of the first support portion 61 is guided by the guide portion 66 before the first wheel 65a in the process in which the housings 2a and 2b reach the assembled state. Since it is guided by the support part 64, the burden on the worker when the cases 2a and 2b are brought together is reduced.

そして、作業台本体部６０は、一対の第一の支持部６１のいずれかに対して着脱自在であるので、当該いずれかの第一の支持部６１にて作業台本体部６０を任意に起立させることできる。したがって、筐体２のメンテナンスの際に筐体２の設置環境に応じて筐体２の両側面にいずれからのアクセスが可能となる。   Since the worktable body 60 is detachable with respect to any one of the pair of first support parts 61, the worktable body 60 is arbitrarily raised by any one of the first support parts 61. Can be made. Accordingly, either side of the housing 2 can be accessed from either side according to the installation environment of the housing 2 during maintenance of the housing 2.

また、配線ダクト７は、筐体２の底部に配置されたことにより、筐体２の重心が筐体２の下部に集中するので、筐体２の設置状態の安定性が向上する。これにより、筐体２の構造補強が不要となり、筐体分離機構１の小型軽量化（例えば、上部枠体２２ａ，２２ｂに具備される筐体分離機構１の軽量化）を図ることができ、また、配線８を収容させる筐体２の製造コストの削減を図ることできる。   Further, since the wiring duct 7 is arranged at the bottom of the housing 2, the center of gravity of the housing 2 is concentrated on the lower portion of the housing 2, so that the stability of the installation state of the housing 2 is improved. This eliminates the need for structural reinforcement of the housing 2 and enables the housing separation mechanism 1 to be reduced in size and weight (for example, the housing separation mechanism 1 provided in the upper frames 22a and 22b can be reduced in weight). Further, the manufacturing cost of the housing 2 that accommodates the wiring 8 can be reduced.

さらに、筐体２ａ，２ｂの会合状態の際に配線ダクト７は筐体２ａ，２ｂに収容される一方で筐体２ａ，２ｂが分離状態の際に配線ダクト７が筐体２ａ，２ｂの間に配置される一方で作業台６の下で配線８は配線ダクト７に保持される。したがって、筐体２ａの内部メンテナンスを行う作業員の作業スペースが確保されるので、メンテナンスの作業性が向上する。   Further, the wiring duct 7 is accommodated in the casings 2a and 2b when the casings 2a and 2b are in a meeting state, while the wiring duct 7 is between the casings 2a and 2b when the casings 2a and 2b are separated. The wiring 8 is held by the wiring duct 7 under the work table 6. Therefore, the work space for the worker who performs the internal maintenance of the housing 2a is secured, so that the maintenance workability is improved.

そして、配線保持部７１の一端縁には配線８をさらに保持する補助配線保持部７２が回動可能に連結されたことにより、筐体２内にて配線８をより安定した状態で保持できる。   Then, the auxiliary wiring holding part 72 that further holds the wiring 8 is rotatably connected to one end edge of the wiring holding part 71, so that the wiring 8 can be held in a more stable state in the housing 2.

また、補助配線保持部７２の保持本体部７２０の両縁には側壁部７２１が一対に立設されたことにより、筐体２内に導入された配線８をより確実に保持できる。   Further, the pair of side wall portions 721 are erected on both edges of the holding main body portion 720 of the auxiliary wiring holding portion 72, so that the wiring 8 introduced into the housing 2 can be held more reliably.

さらに、一対の側壁部７２１のいずれかには、保持本体部７２０に保持された配線８を保護する覆い部７３が着脱自在に備えたことにより、当該いずれかの側壁部７２１にて覆い部７３を任意に起立させることできる。したがって、配線８のメンテナンスの際に筐体２の設置環境に応じて筐体２の両側面にいずれからのアクセスが可能となる。   Further, since any one of the pair of side wall portions 721 is detachably provided with a cover portion 73 that protects the wiring 8 held by the holding main body portion 720, the cover portion 73 is covered by any one of the side wall portions 721. Can stand up arbitrarily. Accordingly, either side of the housing 2 can be accessed depending on the installation environment of the housing 2 during maintenance of the wiring 8.

また、枠体２０ａにおいては、筐体２ａ，２ｂが分離状態の際に配線ダクト７の補助配線保持部７２（特に、保持本体部７２０）が吊り下げ部材９により水平に保持されるので、配線８がより安定して保持される。   Further, in the frame body 20a, the auxiliary wiring holding portion 72 (particularly the holding main body portion 720) of the wiring duct 7 is held horizontally by the suspension member 9 when the casings 2a and 2b are separated from each other. 8 is held more stably.

そして、筐体２ａ，２ｂが会合及び分離する過程では、吊り下げ部材９により枠体からの補助配線保持部７２（特に、保持本体部７２０）の一端縁の引き出しが抑制される。したがって、配線ダクト７が筐体２の下部に配置された状態であっても、筐体２ａ，２ｂの会合及び分離の操作を支障なく行える。   In the process of associating and separating the housings 2a and 2b, the suspension member 9 prevents the one end edge of the auxiliary wiring holding portion 72 (particularly the holding main body portion 720) from being pulled out from the frame. Therefore, even when the wiring duct 7 is disposed in the lower portion of the housing 2, the operations of associating and separating the housings 2a and 2b can be performed without any trouble.
