　図１（ｃ），図５（ａ）（ｂ）に示された開放状態の一対の扉４のうち筐体２の正面開口部２０から少し張り出した一方の扉４の縁部が前方に引っ張り出される。このとき、第一本体部６０は、扉４の支持部４０に連結された連結部材６４によって牽引されて、第一案内部６３によって案内されながら筐体２の前方に移動する。第一本体部６０は前方の移動終点位置に到達すると第一牽引部材６１が伸長した状態で係止部材９の切り欠き部９２が筐体２内の被係止部２２に係止される。一方、第二本体部７０は第二案内部７３によって案内され且つ第二回転減速部１２１によって減速された状態で第二牽引部材６２の伸長力によって後方に移動する。そして、この第二本体部７０の後方への移行により、引き込み動作部６側の一方の連結治具８は開閉動作部７側の他方の連結治具８の押圧を受けると図３（ａ）（ｂ）に示されたように当該他方の連結治具８と連結する。このとき、前記一対の扉４は図１（ａ），図３（ａ）（ｂ）に示されたように閉鎖状態となる。 Of the pair of doors 4 in the open state shown in FIGS. 1 (c) and 5 (a) and 5 (b), the edge of one of the doors 4 slightly protruding from the front opening 20 of the housing 2 is pulled forward. Will be issued. At this time, the first main body portion 60 is pulled by the connecting member 64 connected to the support portion 40 of the door 4, and moves to the front of the housing 2 while being guided by the first guide portion 63. When the first main body portion 60 reaches the forward movement end position, the notch 92 of the locking member 9 is locked to the locked portion 22 in the housing 2 with the first pulling member 61 extended. On the other hand, the second main body 70 is guided by the second guiding portion 73 and is moved rearward by the extension force of the second pulling member 62 in a state of being decelerated by the second rotation decelerating portion 121. When one connecting jig 8 on the pull-in operation unit 6 side receives the pressing of the other connecting jig 8 on the opening / closing operation unit 7 side due to the backward movement of the second main body portion 70, as shown in FIG. As shown in (b), it is connected to the other connecting jig 8. At this time, the pair of doors 4 is in the closed state as shown in FIGS. 1 (a) and 3 (a) and 3 (b).
　（第一実施形態の効果）
　以上の扉開閉機構１によれば、開放状態の扉４が収容機構５によって筐体２内に収容されるので、筐体２の開口正面部における物理的障害が解消され、筐体２に収容された電子機器３の操作時やメンテナンス時の電子機器３のアクセス性が向上する。 (Effect of the first embodiment)
According to the door opening and closing mechanism 1 described above, since the door 4 in the open state is accommodated in the housing 2 by the accommodation mechanism 5, the physical obstacle in the opening front portion of the housing 2 is eliminated and the housing 2 is accommodated. The accessibility of the electronic device 3 at the time of operation or maintenance of the electronic device 3 is improved.
　特に、収容機構５においては、扉４を開閉させる開閉動作部７が引き込み動作部６によって筐体２内で前後方向に移動可能となっている。特に、引き込み動作部６の第一本体部６０は第一牽引部材６１の伸縮力によって前後方向に移動可能である一方で開閉動作部７の第二本体部７０は第二牽引部材６２の伸縮力によって前後方向に移動可能となる。したがって、電気的な動力源を要することなく扉４の開閉動作及び筐体２内への収容が行える。 In particular, in the housing mechanism 5, the opening / closing operation unit 7 for opening / closing the door 4 is movable in the front-rear direction in the housing 2 by the pull-in operation unit 6. In particular, the first main body portion 60 of the pull-in operation portion 6 is movable in the front-rear direction by the expansion and contraction force of the first pulling member 61 while the second main body portion 70 of the opening and closing operation portion 7 is the expansion and contraction force of the second pulling member 62 Can be moved back and forth. Therefore, the opening and closing operation of the door 4 and the housing in the housing 2 can be performed without requiring an electric power source.
　また、第一本体部６０の往復動作は第一減速機構１１によって減速制御された状態となっている。特に、第二減速機構１２においては、第一本体部６０に具備された第一回転減速部１１１が筐体２に具備された第一受け部１１２と噛み合った状態で第一本体部６０の往復動が減速制御される。したがって、第一本体部６０のスムーズ且つ静粛な往復動作が可能となる。また、第一本体部６０が往復動作する際の筐体２の振動も抑制される。 Further, the reciprocation of the first main body 60 is controlled to be decelerated by the first reduction mechanism 11. In particular, in the second reduction gear mechanism 12, the first rotation reduction portion 111 included in the first main body portion 60 reciprocates in a state in which the first rotation reduction portion 111 meshes with the first receiving portion 112 included in the housing 2. The motion is controlled to slow down. Therefore, smooth and quiet reciprocation of the first main body 60 is possible. Moreover, the vibration of the housing | casing 2 at the time of the 1st main-body part 60 reciprocatingly acting is also suppressed.
　さらに、第二本体部７０の往復動作も第二減速機構１２によって減速制御された状態となっている。特に、第二減速機構１２においては、第二本体部７０の第二回転減速部１２１が第一本体部６０の第二受け部１２２と噛み合うことで第二本体部７０の往復動が減速制御される。したがって、第二本体部７０のスムーズ且つ静粛な往復動作が可能となる。また、第二本体部７０の往復動作時の第一本体部６０並びに筐体２の振動も抑制される。 Furthermore, the reciprocation of the second main body 70 is also controlled to be decelerated by the second reduction mechanism 12. In particular, in the second reduction gear mechanism 12, the reciprocation of the second main body 70 is controlled to be reduced by the engagement of the second rotational reduction portion 121 of the second main body 70 with the second receiving portion 122 of the first main body 60. Ru. Therefore, smooth and quiet reciprocation of the second main body 70 is possible. Further, the vibration of the first main body portion 60 and the casing 2 at the time of the reciprocation operation of the second main body portion 70 is also suppressed.
　そして、扉４が閉鎖状態となる時点で、引き込み動作部６と開閉動作部７とは一対の連結治具８によって連結された状態となる。特に、引き込み動作部６側の連結治具８は、開閉動作部７側の連結治具８の押圧を受けて当該他方の連結治具８との連結とその解除が可能となっている。したがって、扉４のワンタッチ操作により扉４が開閉動作するので、扉４の開閉操作が容易となる。 When the door 4 is closed, the pull-in operation unit 6 and the open / close operation unit 7 are connected by the pair of connection jigs 8. In particular, the connection jig 8 on the pull-in operation unit 6 side can receive the pressure of the connection jig 8 on the opening / closing operation unit 7 and can be connected to and released from the other connection jig 8. Accordingly, since the door 4 is opened and closed by the one-touch operation of the door 4, the opening and closing operation of the door 4 is facilitated.
　また、収容機構５において、係止部材９は第一本体部６０が前方の移動終点位置に到達すると第一本体部６０を筐体２内に係止させる一方で扉４が開放状態となる位置に第二本体部７０が到達すると当該解除が解除させる。したがって、扉４が閉鎖状態となり得る筐体２内の第一本体部６０の位置を安定的に維持できる。 In the housing mechanism 5, the locking member 9 locks the first main body 60 in the housing 2 when the first main body 60 reaches the forward movement end position, while the door 4 is in the open state. When the second main body portion 70 arrives, the release is released. Therefore, the position of the first main body 60 in the housing 2 where the door 4 can be closed can be stably maintained.
　以上のように、本実施形態の扉開閉機構１によれば、操作性、さらには、外観的にも優れた扉の開閉機構が提供される。 As described above, according to the door opening and closing mechanism 1 of the present embodiment, the door opening and closing mechanism excellent in operability and appearance is provided.

　（第二実施形態の扉開閉機構１の動作例）
　図７～９を参照しながら第二実施形態の扉開閉機構１の動作例について説明する。 (Operation example of the door opening and closing mechanism 1 of the second embodiment)
An operation example of the door opening and closing mechanism 1 of the second embodiment will be described with reference to FIGS. 7 to 9.
　先ず、閉鎖状態の扉４を開放状態にする際の動作例について説明する。 First, an operation example for opening the closed door 4 will be described.
　図７（ａ）（ｂ）に示された閉鎖状態の一対の扉４のうちの上方の扉４の摘み部４１が利用者の手により手前に引かれると、上方の扉４の支持部４０は図８（ａ）（ｂ）に示したように筐体２の外側方向に回動する。これに伴い、上方の扉４の連結部材７１は支持部４０の回動に従動して第二本体部７４を前方に移動させる。このとき、第二本体部７４の第二被案内部８２は、引き込み動作部６の第一本体部６０上の第二案内部７３により案内されながら、第二案内部７３と第二被案内部８２との間に介在する粘性流動体により減速された状態で前方に移行する。一方、下方の扉４の連結部材７１は第二本体部７４の第二被案内部８２に従動して下方の扉４の支持部４０を前記外側方向に回動させる。また、第二本体部７４側の係止部６８は、第一本体部６０側の動作規定部６６における動作規定盤６７の孔６９から解放された後、第一牽引部材６１の収縮力により牽引された状態で動作規定盤６７の前方側端部にて係止する。このとき、上下一対の扉４は図８（ａ）（ｂ）に示したように開放状態となる。 When the knob 41 of the upper door 4 of the pair of closed doors 4 shown in FIGS. 7 (a) and 7 (b) is pulled forward by the user's hand, the support 40 of the upper door 4 is As shown in FIGS. 8 (a) and 8 (b), the housing 2 is rotated outward. Along with this, the connecting member 71 of the upper door 4 is driven by the rotation of the support 40 to move the second main body 74 forward. At this time, the second guided portion 82 of the second main body portion 74 is guided by the second guiding portion 73 on the first main body portion 60 of the pull-in operation portion 6, and the second guiding portion 73 and the second guided portion It moves forward while being decelerated by the viscous fluid interposed therebetween. On the other hand, the connecting member 71 of the lower door 4 is driven by the second guided portion 82 of the second main body 74 to rotate the support portion 40 of the lower door 4 in the outward direction. Further, the locking portion 68 on the second main body portion 74 side is released from the hole 69 of the operation defining board 67 in the operation defining portion 66 on the first main body portion 60 side, and then pulled by the contraction force of the first pulling member 61. The front end of the operation regulation board 67 is locked in this state. At this time, the pair of upper and lower doors 4 is in the open state as shown in FIGS. 8 (a) and 8 (b).

At this time, since the first guided portion 81 of the first main body portion 60 is not loaded with the weight, it is guided by the first guiding portion 63 of the inner side surface 21 of the housing 2, It is pulled by the contraction force of the first pulling member 61 and moves rearward. At this time, the first guided portion 81 moves rearward while being decelerated by the viscous fluid interposed between the first guided portion 81 and the first guiding portion 63. Then, when the first main body portion 60 abuts against the contact portion 65 and is restrained, as shown in FIGS. 9A and 9B, the second main body portion 74 of the opening / closing operation portion 7 is further casing 2 The pair of doors 4 are accommodated in the housing 2 by being drawn into the inside.
　次に、開放状態の扉４を閉鎖状態にする際の扉開閉機構１の動作例について説明する。 Next, an operation example of the door opening / closing mechanism 1 when the open door 4 is closed will be described.

The upper and lower doors 4 are withdrawn from the front opening 20 as shown in b). At this time, the first guided portion 81 of the first main body portion 60 is pulled by the connecting member 64 connected to the supporting portion 40 of the door 4 and guided by the first guiding portion 63 while the first guiding portion 63 In the state decelerated by the viscous fluid interposed between the first and second guided portions 81 and 81.
　そして、図８（ａ）（ｂ）の状態で扉４の摘み部４１から利用者の手が離されると、扉４及び摘み部４１の自重により上方の扉４の支持部４０は筐体２の内側方向に回動する。これに伴い、上方の扉４の連結部材７１は支持部４０の回動に従動して第二本体部７４を後方に移動させる。このとき、第二本体部７４の第二被案内部８２は、引き込み動作部６の第一本体部６０上の第二案内部７３により案内されながら、この第二案内部７３と第二被案内部８２との間に介在する粘性流動体により減速された状態で後方に移行する。 Then, when the user's hand is released from the knob 41 of the door 4 in the state shown in FIGS. 8 (a) and 8 (b), the support 40 of the upper door 4 is the housing 2 by the weight of the door 4 and the knob 41. In the inward direction of the Along with this, the connecting member 71 of the upper door 4 is driven by the rotation of the support 40 to move the second main body 74 rearward. At this time, while the second guided portion 82 of the second main body portion 74 is guided by the second guiding portion 73 on the first main body portion 60 of the pull-in operation portion 6, the second guided portion 73 and the second guided portion It moves rearward while being decelerated by the viscous fluid interposed between it and the portion 82.
　一方、下方の扉４の連結部材７１は第二本体部７４の第二被案内部８２に従動して下方の扉４の支持部４０を前記内側方向に回動させる。そして、第二本体部７４側の係止部６８が、第一本体部６０側の動作規定盤６７の孔６９に係止されると、上下一対の扉４は図７（ａ）（ｂ）に示したように閉鎖状態となる。 On the other hand, the connecting member 71 of the lower door 4 is driven by the second guided portion 82 of the second main body 74 to rotate the support portion 40 of the lower door 4 in the inward direction. Then, when the locking portion 68 on the second main body portion 74 side is locked in the hole 69 of the operation defining board 67 on the first main body portion 60 side, the pair of upper and lower doors 4 is as shown in FIGS. It will be closed as shown in.

Therefore, the manufacturing cost of the case 2 having the opening and closing mechanism of the door 4 and the door opening and closing mechanism is significantly reduced.
　また、一対の扉４のうち上方の扉４の下縁部には、摘み部４１が具備されており、扉４を直感的に操作でき、上方の扉４が筐体２から引き出された際に摘み部４１の自重がこの扉４に付加されると共に摘み部４１が搖動するので、扉４の開閉動作性がさらに向上する。 Further, a knob 41 is provided at the lower edge of the upper door 4 of the pair of doors 4 so that the door 4 can be operated intuitively, and when the upper door 4 is pulled out from the housing 2 Since the weight of the knob 41 is added to the door 4 and the knob 41 swings, the opening and closing operability of the door 4 is further improved.
