Description

本発明は、第一連結対象物に第二連結対象物を開閉可能に連結するヒンジ及び当該ヒンジを備えた電子機器に関する。 The present invention relates to a hinge that connects a second connection object to a first connection object in an openable and closable manner, and to an electronic device that includes the hinge.

従来、複写機、ファクシミリ、スキャナー等、オフィスで使用される事務機器の多くは、その本体の上面に原稿読み取り部（コンタクトガラス）を具備するとともに、当該原稿読み取り部を覆う原稿圧着板を具備する。原稿圧着板は、原稿読み取り部に載置された原稿を原稿読み取り部に密着させるとともに原稿読み取り部に対する原稿の位置を保持するものである。 Conventionally, many office equipment such as copiers, facsimiles, and scanners are equipped with a document reading unit (contact glass) on the top surface of the main body, as well as a document pressure plate that covers the document reading unit. The document pressure plate presses the document placed on the document reading unit into close contact with the document reading unit and maintains the position of the document relative to the document reading unit.

事務機器の本体と原稿圧着板とを連結する器具としては、第一ウイング部材と、第一ウイング部材に固定されるカム部材と、第一ウイング部材に回動軸を介して回動可能に連結される第二ウイング部材と、カム部材に接近する方向およびカム部材から離間する方向に移動可能なスライド部材と、スライド部材をカム部材に接近する方向に付勢することによりスライド部材をカム部材に当接させる付勢部材と、を具備するヒンジが知られている。 A known device for connecting the main body of an office machine to an original cover plate is a hinge that includes a first wing member, a cam member fixed to the first wing member, a second wing member rotatably connected to the first wing member via a pivot shaft, a slide member that can move toward and away from the cam member, and a biasing member that biases the slide member toward the cam member, thereby bringing the slide member into contact with the cam member.

また、ヒンジには、第二ウイング部材は中間部材と固定部材とを備え、中間部材に対して固定部材が開いた状態（リフト状態）として、複合機の本体に対して原稿圧着板を持ち上げた状態にして、本体（コンタクトガラス）と原稿圧着板との間に比較的分厚い原稿を配置したり、また、メンテナンスや点検等を行い易くするものがある。
さらに、このようなヒンジを備える事務機においては、中間部材と固定部材とが開いた状態（リフト状態）において、ヒンジの後方から中間部材と固定部材との間に、例えば工具や衣服や手指等の異物が入り込んで挟まることを防止する異物挟み防止部を備えるものがある（特許文献１参照）。 In addition, some hinges have a second wing member that is equipped with an intermediate member and a fixed member, and when the fixed member is in an open state (lift state) relative to the intermediate member, the document pressure plate is raised relative to the main body of the multifunction device, allowing a relatively thick document to be placed between the main body (contact glass) and the document pressure plate, and also making it easier to perform maintenance and inspection.
Furthermore, some office machines equipped with such hinges are equipped with a foreign object pinch prevention section that prevents foreign objects such as tools, clothing, or fingers from entering and becoming pinched between the intermediate member and the fixed member from behind the hinge when the intermediate member and the fixed member are open (lifted state) (see Patent Document 1).

特開２００２－１３１９９０号公報JP 2002-131990 A

しかしながら、このような事務機では、異物挟み防止部が原稿圧着板に設けられており、ヒンジを連結対象物に組付ける際に、原稿圧着板から垂れ下がった異物挟み防止部が邪魔になって、ヒンジを連結対象物に組付ける作業が億劫なものとなる場合があった。 However, in such office machines, the foreign object pinch prevention part is provided on the document pressing plate, and when assembling the hinge to the connected object, the foreign object pinch prevention part hanging down from the document pressing plate can get in the way, making the task of assembling the hinge to the connected object tedious.

本発明は以上の如き状況に鑑みてなされたものであり、組付け作業を比較的容易に行うことができるヒンジを提供することを課題とする。 The present invention was made in consideration of the above situation, and aims to provide a hinge that can be assembled relatively easily.

以下で詳述する実施形態に係るヒンジはいずれも複合機１の本体２に原稿圧着板３を開閉可能（回動可能）に連結する用途に用いられるが、本発明に係るヒンジの用途はこれに限定されない。
すなわち、本発明に係るヒンジは、「二つの部材のうちの一方の部材（第一連結対象物）に他方の部材（第二連結対象物）を開閉可能に連結する用途」に広く適用可能であり、例えば、スキャナー、ファクス、およびコピー機、若しくは複合機等のＯＡ機器、自動車、便座、または、炊飯器等の各種電子機器等に用いられる。ヒンジが二つの部材のうちの一方の部材に他方の部材を開閉可能に連結するものとして、例えば、プリンタの本体に回動可能に連結される扉部分、複合機の本体に回動可能に連結される原稿圧着装置、スタンドに回動可能に連結されるディスプレイ、便座に回動可能に連結される便座、自動車の車体に回動可能に連結されるボンネット等がある。 The hinges according to the embodiments described in detail below are all used to connect the original cover 3 to the main body 2 of the multifunction printer 1 in an openable/closable (rotatable) manner, but the use of the hinges according to the present invention is not limited to this.
That is, the hinge according to the present invention is widely applicable to "applications for connecting one of two members (first connection object) to the other member (second connection object) in an openable/closable manner", and is used in, for example, office equipment such as scanners, faxes, copiers, and multifunction machines, automobiles, toilet seats, and various electronic devices such as rice cookers, etc. Examples of hinges for connecting one of two members to the other member in an openable/closable manner include a door portion rotatably connected to the main body of a printer, an original pressing device rotatably connected to the main body of a multifunction machine, a display rotatably connected to a stand, a toilet seat rotatably connected to a toilet seat, and a bonnet rotatably connected to the body of an automobile.

以下の説明では、原稿圧着板３が閉じているとき（原稿圧着板３の下面が本体２の上面に当接しているとき）の原稿圧着板３の回動角度θ（より厳密には、本体２に対する原稿圧着板３の回動角度θ）を「０度」とし、原稿圧着板３が開く方向に回動した場合に回動角度θが増加する（回動角度θが正になる）ように原稿圧着板３の回動角度θを定義する（図１参照）。本実施形態において、本体２に対する原稿圧着板３の回動角度θは、後述する第二ウイング部材の第一ウイング部材に対する閉状態からの回動角度とも一致する。このため、本実施形態では双方とも「回動角度θ」と記載する。 In the following description, the rotation angle θ of the original pressure plate 3 when it is closed (when the lower surface of the original pressure plate 3 is in contact with the upper surface of the main body 2) (more precisely, the rotation angle θ of the original pressure plate 3 relative to the main body 2) is defined as "0 degrees", and the rotation angle θ of the original pressure plate 3 is defined so that the rotation angle θ increases (the rotation angle θ becomes positive) when the original pressure plate 3 rotates in the opening direction (see FIG. 1). In this embodiment, the rotation angle θ of the original pressure plate 3 relative to the main body 2 also coincides with the rotation angle of the second wing member from the closed state relative to the first wing member, which will be described later. For this reason, in this embodiment, both are described as "rotation angle θ".

以下では、図１から図１３を用いて本発明に係るヒンジの一実施形態であるヒンジ１００について説明する。なお、開閉装置は、本体２に対して原稿圧着板３を開閉可能とする装置としてヒンジ１００を用いて構成したものを示す。

Further, a through hole for mounting the pressure receiving portion 73 is formed in the side plates 32 .

第二回動軸７２は、上部固定部材３０を中間部材２０に回動可能に連結する回動軸を成す部材である。第二回動軸７２は概ね円柱形状の部材であり、上部固定部材３０及び中間部材２０の前部に挿通される。その結果、上部固定部材３０は第二回動軸７２を介して中間部材２０に回動可能に連結される。 The second pivot shaft 72 is a member that forms a pivot shaft that rotatably connects the upper fixing member 30 to the intermediate member 20. The second pivot shaft 72 is a roughly cylindrical member that is inserted through the front parts of the upper fixing member 30 and the intermediate member 20. As a result, the upper fixing member 30 is rotatably connected to the intermediate member 20 via the second pivot shaft 72.

受圧部７３は、ピン状に構成される。受圧部７３は、側板３２・３２の貫通孔に挿通されて上部固定部材３０に固定される。受圧部７３のスライダ側の面は、カム面として構成され、第二スライダ５０のカム当接部５２と当接する。
なお、受圧部７３は、ピン状のものに限定されるものではなく、板状の部材を折り曲げて構成すること等、他の構成とすることもできる。 The pressure receiving portion 73 is configured in a pin shape. The pressure receiving portion 73 is inserted into the through hole of the side plates 32 and fixed to the upper fixing member 30. The surface of the pressure receiving portion 73 on the slider side is configured as a cam surface and abuts against the cam abutment portion 52 of the second slider 50.
It should be noted that the pressure receiving portion 73 is not limited to a pin-shaped portion, but may have other configurations, such as a configuration formed by bending a plate-shaped member.

第一スライダ４０は本発明に係るスライド部材の実施の一形態である。第一スライダ４０は樹脂材料からなる。
第一スライダ４０は、有底に構成される本体４１と、本体４１の底部後面から後方（本体４１の外側）に突出するカム当接部４２とを備える。また、第一スライダ４０は、カム当接部４２の後面において、カム部材７５に当接するように構成される。第一スライダ４０（本体４１）にはバネ６０の後端部を収容するバネ受け穴が形成されている。第一スライダ４０は中間部材２０の内部における後部で前後方向に摺動可能に収容される。 The first slider 40 is an embodiment of a sliding member according to the present invention. The first slider 40 is made of a resin material.
The first slider 40 includes a main body 41 having a bottom, and a cam abutment portion 42 protruding rearward (outside the main body 41) from the rear surface of the bottom of the main body 41. The first slider 40 is configured to abut against a cam member 75 at the rear surface of the cam abutment portion 42. A spring receiving hole that accommodates the rear end portion of the spring 60 is formed in the first slider 40 (main body 41). The first slider 40 is accommodated in the rear portion of the interior of the intermediate member 20 so as to be slidable in the front-rear direction.

第二スライダ５０は本発明に係るスライド部材の実施の一形態である。第二スライダ５０は樹脂材料からなる。
第二スライダ５０は後方が開口し前面に底部を備える。第二スライダ５０は、底部前面にカム当接部５２を備える。第二スライダ５０にはバネ６０の前端部を収容するバネ受け穴が形成されている。 The second slider 50 is an embodiment of a sliding member according to the present invention. The second slider 50 is made of a resin material.
The second slider 50 is open at the rear and has a bottom at the front. The second slider 50 has a cam abutment portion 52 at the front surface of the bottom. A spring receiving hole for accommodating the front end of a spring 60 is formed in the second slider 50.

本実施形態では、「中間部材２０、上部固定部材３０、第一スライダ４０、第二スライダ５０、第二回動軸７２および受圧部７３を合わせたもの」が本発明に係る第二ウイング部材の実施の一形態に相当する。言い換えれば、本発明に係る第二ウイング部材の実施の一形態は、中間部材２０、上部固定部材３０、第一スライダ４０、第二スライダ５０、第二回動軸７２および受圧部７３を具備する。そして、上部固定部材３０が原稿圧着板３に固定されることにより、第二ウイング部材は第二連結対象物に固定される。 In this embodiment, the combination of the intermediate member 20, the upper fixed member 30, the first slider 40, the second slider 50, the second pivot shaft 72, and the pressure receiving portion 73 corresponds to one embodiment of the second wing member according to the present invention. In other words, one embodiment of the second wing member according to the present invention comprises the intermediate member 20, the upper fixed member 30, the first slider 40, the second slider 50, the second pivot shaft 72, and the pressure receiving portion 73. Then, the upper fixed member 30 is fixed to the original cover 3, and the second wing member is fixed to the second connection object.

本実施形態においては、第二ウイング部材が第一ウイング部材に最も近接した状態を第二ウイング部材の「閉状態」（原稿圧着板３が本体２に対して閉じている状態）とする（図９参照）。閉状態とは、第二ウイング部材の第一ウイング部材に対する閉状態からの回動角度θが０度となる状態を指す。また、第二ウイング部材が第一ウイング部材から最も離間した状態を第二ウイング部材の「開状態」とする（図８参照）。開状態とは、原稿圧着板３が本体２に対して開いている状態であり、回動角度θが９０度となる状態を指す。 In this embodiment, the state in which the second wing member is closest to the first wing member is the "closed state" of the second wing member (the document cover 3 is closed relative to the main body 2) (see FIG. 9). The closed state refers to a state in which the rotation angle θ of the second wing member relative to the first wing member from the closed state is 0 degrees. Also, the state in which the second wing member is furthest away from the first wing member is the "open state" of the second wing member (see FIG. 8). The open state refers to a state in which the document cover 3 is open relative to the main body 2 and the rotation angle θ is 90 degrees.

バネ６０は、付勢部材の実施の一形態であり、金属製の巻きバネ（圧縮バネ）で構成される。バネ６０は中間部材２０の内部（第一スライダ４０と第二スライダ５０とのバネ受け孔）に収容される。 The spring 60 is one embodiment of a biasing member, and is made of a metal coil spring (compression spring). The spring 60 is housed inside the intermediate member 20 (in the spring receiving holes of the first slider 40 and the second slider 50).

バネ６０の後端部は第一スライダ４０に形成されたバネ受け穴に挿入されてバネ受け穴の底面に当接する。また、バネ６０の前端部は第二スライダ５０に形成されたバネ受け穴に挿入されてバネ受け穴の底面に当接する。 The rear end of the spring 60 is inserted into a spring receiving hole formed in the first slider 40 and abuts against the bottom surface of the spring receiving hole. The front end of the spring 60 is inserted into a spring receiving hole formed in the second slider 50 and abuts against the bottom surface of the spring receiving hole.

バネ６０が発生する付勢力、すなわち、圧縮される方向に弾性変形したバネ６０が元の形状（外力が作用していないときの形状）に戻ろうとする力（弾性力）により、第一スライダ４０は中間部材２０の長手方向のうち第一回動軸７１に接近する方向に付勢され、第二スライダ５０は中間部材２０の長手方向のうち受圧部７３に接近する方向に付勢される。 The spring 60 generates a biasing force, i.e., the force (elastic force) that causes the spring 60, which has been elastically deformed in the direction of compression, to return to its original shape (the shape when no external force is acting), biases the first slider 40 in the longitudinal direction of the intermediate member 20 in a direction approaching the first pivot shaft 71, and biases the second slider 50 in the longitudinal direction of the intermediate member 20 in a direction approaching the pressure-receiving portion 73.

ダンパー６２は、第一スライダ４０及び第二スライダ５０のバネ受け穴に収容されている。ダンパー６２の本体部は、第二スライダ５０の底部に固定され、その先端部が第一回動軸７１側に突出する。ダンパー６２は、第一スライダ４０の底部によって先端部が押圧力を受けたときに反力を発生させる。このため、当該反力により第一スライダ４０が移動する速度が小さくなり、ダンパー６２による緩衝効果が発生する。ダンパー６２は一般的な流体ダンパーで構成される。 The damper 62 is housed in the spring receiving holes of the first slider 40 and the second slider 50. The main body of the damper 62 is fixed to the bottom of the second slider 50, and its tip protrudes toward the first rotating shaft 71. The damper 62 generates a reaction force when the tip receives a pressing force from the bottom of the first slider 40. Therefore, the reaction force reduces the speed at which the first slider 40 moves, and a buffering effect is generated by the damper 62. The damper 62 is configured as a general fluid damper.

カム部材７５は、概ね円柱形状（ピン状）の部材である。カム部材７５は、第一回動軸７１の前下方に配置され、下部固定部材１０に取付けられる。カム部材７５は、第一スライダ４０のカム当接部４２（カム当接部４２の後面）に当接する。第二ウイング部材を閉状態とした際には、第一スライダ４０のカム当接部４２がカム部材７５に当接するとともに、第二スライダ５０のカム当接部５２が受圧部７３に当接する。また、第二ウイング部材の回動角度θ＞６０度の場合には、第一スライダ４０のカム当接部４２がカム部材７５から離間した状態となる。 The cam member 75 is a generally cylindrical (pin-shaped) member. The cam member 75 is disposed below and in front of the first pivot shaft 71, and is attached to the lower fixed member 10. The cam member 75 abuts against the cam abutment portion 42 (rear surface of the cam abutment portion 42) of the first slider 40. When the second wing member is in the closed state, the cam abutment portion 42 of the first slider 40 abuts against the cam member 75, and the cam abutment portion 52 of the second slider 50 abuts against the pressure receiving portion 73. In addition, when the pivot angle θ of the second wing member is greater than 60 degrees, the cam abutment portion 42 of the first slider 40 is separated from the cam member 75.

第一スライダ４０のカム当接部４２がカム部材７５に当接するとともに、第二スライダ５０のカム当接部５２が受圧部７３に当接する結果として、バネ６０に生じる弾性力により、中間部材２０（第二ウイング部材）は下部固定部材１０に対して開く方向に回動するように付勢され、上部固定部材３０は中間部材２０に対して閉じる方向に回動するように付勢される。この際、ダンパー６２の先端部は第二スライダ５０の底部によって押圧され、ダンパー６２の本体部側に押し込まれる。 When the cam abutment portion 42 of the first slider 40 abuts against the cam member 75 and the cam abutment portion 52 of the second slider 50 abuts against the pressure receiving portion 73, the elastic force generated in the spring 60 urges the intermediate member 20 (second wing member) to rotate in an opening direction relative to the lower fixed member 10, and urges the upper fixed member 30 to rotate in a closing direction relative to the intermediate member 20. At this time, the tip of the damper 62 is pressed by the bottom of the second slider 50 and pushed into the main body of the damper 62.

本実施形態では、第二ウイング部材の第一ウイング部材に対する閉状態からの回動角度θが０度から第一の所定角度φ１までの第一領域にあるとき（０度≦θ≦φ１のとき）、バネ６０に生じる弾性力により、第二ウイング部材を第一ウイング部材に対して開状態となる方向に回動させる構成としている。例えば、第一の所定角度φ１は６０度（回動角度θ＝第一の所定角度φ１＝６０度）に設定されている。なお、第一の所定角度φ１は６０度以外の他の角度に設定することも可能である。 In this embodiment, when the rotation angle θ of the second wing member from the closed state relative to the first wing member is in a first region from 0 degrees to a first predetermined angle φ1 (when 0 degrees≦θ≦φ1), the elastic force generated in the spring 60 rotates the second wing member in a direction to open the first wing member. For example, the first predetermined angle φ1 is set to 60 degrees (rotation angle θ = first predetermined angle φ1 = 60 degrees). Note that the first predetermined angle φ1 can also be set to an angle other than 60 degrees.

本実施形態においては、上部固定部材３０に固定された原稿圧着板３の自重に起因してヒンジ１００を閉じようとする回転力と、バネ６０の付勢力に起因してヒンジ１００を開こうとする回転力と、が概ね平衡するように、第一スライダ４０のカム当接部４２またはカム部材７５の形状等が予め定められる。
このように構成することにより、複合機１の本体２に対する原稿圧着板３の回動角度θが０度からφ１までの範囲において作業者が原稿圧着板３から手を離した場合には、回動角度θが保持される。 In this embodiment, the shape of the cam abutment portion 42 of the first slider 40 or the cam member 75 is predetermined so that the rotational force attempting to close the hinge 100 due to the weight of the original pressure plate 3 fixed to the upper fixed member 30 and the rotational force attempting to open the hinge 100 due to the biasing force of the spring 60 are roughly balanced.
By configuring in this manner, when the operator releases the document cover 3 while the rotation angle θ of the document cover 3 relative to the main body 2 of the multifunction printer 1 is in the range from 0 degrees to φ1, the rotation angle θ is maintained.

フェンス部材８０は、カム部材７５の近傍において、カム部材７５及び第一スライダ４０のカム当接部４２の下方（第二ウイング部材の開状態ではカム部材７５と第一スライダ４０の当接部分の前方）に配置される。フェンス部材８０は、中間部材２０の閉状態から開状態まで（中間部材２０の回動範囲の全域に亘って）、第一スライダ４０及びカム部材７５の外側から、第一スライダ４０のカム当接部４２とカム部材７５との当接部分側に異物（例えば原稿等）が入り込むことを防止する。フェンス部材８０は、カム部材７５（第一スライダ４０のカム当接部４２とカム部材７５との当接部分）を下方外側または前方外側等から見えないようにして、外側との空間を遮蔽するように構成される。
フェンス部材８０は、第一スライダ４０（カム当接部４２）にぶら下がるように（回動可能に）支持される。フェンス部材８０は、中間部材２０の回動動作または第一スライダ４０の移動動作とともに移動可能に構成される。 The fence member 80 is disposed near the cam member 75 and below the cam abutment portion 42 of the cam member 75 and the first slider 40 (in front of the abutment portion of the cam member 75 and the first slider 40 when the second wing member is in the open state). The fence member 80 prevents foreign matter (e.g., a document, etc.) from entering the abutment portion side of the cam abutment portion 42 of the first slider 40 and the cam member 75 from the outside of the first slider 40 and the cam member 75 from the closed state to the open state of the intermediate member 20 (over the entire range of rotation of the intermediate member 20). The fence member 80 is configured to block the space with the outside by making the cam member 75 (the abutment portion of the cam abutment portion 42 of the first slider 40 and the cam member 75) invisible from the lower outside or the front outside, etc.
The fence member 80 is supported so as to be suspended (rotatable) from the first slider 40 (the cam abutment portion 42). The fence member 80 is configured to be movable together with the pivoting movement of the intermediate member 20 or the moving movement of the first slider 40.

フェンス部材８０は、本体部８１と、一対のアーム８２・８２と、を具備する。
本体部８１は、カム部材７５の左右幅と略同一の板状に構成される。
アーム８２は、本体部８１の左右上端部からそれぞれ外側に突出してさらに上方に突出する。アーム８２は、その上方の突出側の端部において左右方向内側に突出する凸部を有する。
第一スライダ４０のカム当接部４２の左右の側面略中央部に凹部をそれぞれ備え、当該凹部にフェンス部材８０の左右の凸部がそれぞれ挿入されることによって、フェンス部材８０が第一スライダ４０（カム当接部４２）に支持される。 The fence member 80 includes a main body portion 81 and a pair of arms 82 .
The main body portion 81 is formed in a plate shape having a width substantially equal to the left-right width of the cam member 75 .
The arms 82 protrude outward and then upward from the left and right upper ends of the main body 81. The arms 82 have convex portions at the upper protruding ends that protrude inward in the left-right direction.
The cam abutment portion 42 of the first slider 40 has a recess at approximately the center of each of the left and right side surfaces, and the left and right protrusions of the fence member 80 are inserted into the recesses, thereby supporting the fence member 80 on the first slider 40 (cam abutment portion 42).

このように、フェンス部材８０は、第一スライダ４０にぶら下がるように支持されて、カム部材７５近傍においてカム部材７５及び第一スライダ４０のカム当接部４２との下方（第二ウイング部材の開状態ではカム部材７５と第一スライダ４０の当接部分の前方）に配置され、第一スライダ４０及びカム部材７５の外側から、第一スライダ４０のカム当接部４２とカム部材７５との当接部分側に異物（例えば原稿等）が入り込むことを防止することから、第二ウイング部材の閉状態から開状態まで、例えば、本体２の上面に配置された原稿が第一スライダ４０のカム当接部４２とカム部材７５との当接部分側に入り込んで、当該原稿にオイルが付着すること等を確実に防止することができる。
また、フェンス部材８０は、第一スライダ４０のカム当接部４２とカム部材７５との当接部分外側から見えないようにして外側との空間を遮蔽するように構成されることから、樹脂素材等で構成される部材（第一スライダ４０等）の露出する部分を低減させて、ヒンジ１００を比較的難燃性の高い構成とすることができる。 In this way, the fence member 80 is supported so as to hang from the first slider 40, and is positioned near the cam member 75 and below the cam member 75 and the cam abutment portion 42 of the first slider 40 (in front of the abutment portion between the cam member 75 and the first slider 40 when the second wing member is in the open state), and prevents foreign matter (such as a document) from entering the abutment portion between the cam abutment portion 42 of the first slider 40 and the cam member 75 from the outside of the first slider 40 and the cam member 75. Therefore, from the closed state to the open state of the second wing member, for example, a document placed on the upper surface of the main body 2 can be reliably prevented from entering the abutment portion between the cam abutment portion 42 of the first slider 40 and the cam member 75, and causing oil to adhere to the document.
In addition, the fence member 80 is configured to block the space between the outside and the contact portion between the cam abutment portion 42 of the first slider 40 and the cam member 75 so that it is not visible from the outside. This reduces the exposed portion of the member (such as the first slider 40) made of a resin material or the like, making the hinge 100 relatively flame-retardant.

下部固定部材１０に対して中間部材２０が開いた状態（例えば、下部固定部材１０に対して中間部材２０が２０度開いた状態）で、且つ、中間部材２０に対して上部固定部材３０が開いた状態（例えば、上部固定部材３０が下部固定部材１０に対して０度の状態）とすることができる。このような状態とすることによって、複合機１の本体２に対して原稿圧着板３を持ち上げた状態にして、本体２（本体２の上端のコンタクトガラス）と原稿圧着板３との間に比較的分厚い原稿を配置することができ、また、メンテナンスや点検等を行い易くする。
以下において、中間部材２０に対して上部固定部材３０が開いた状態を便宜上「リフト状態」とし、また、中間部材２０に対して上部固定部材３０が閉じた状態（中間部材２０と上部固定部材３０とが最も近接した状態）を便宜上「リフト解消状態」として説明する。 It is possible to set the intermediate member 20 in an open state relative to the lower fixed member 10 (for example, a state in which the intermediate member 20 is opened 20 degrees relative to the lower fixed member 10) and the upper fixed member 30 in an open state relative to the intermediate member 20 (for example, a state in which the upper fixed member 30 is at 0 degrees relative to the lower fixed member 10). By setting it in this state, the document pressing plate 3 can be raised relative to the main body 2 of the multifunction device 1, and a relatively thick document can be placed between the main body 2 (the contact glass at the upper end of the main body 2) and the document pressing plate 3, and also maintenance, inspection, and the like can be easily performed.
In the following, for convenience, the state in which the upper fixing member 30 is open relative to the intermediate member 20 will be referred to as the "lifted state", and the state in which the upper fixing member 30 is closed relative to the intermediate member 20 (the state in which the intermediate member 20 and the upper fixing member 30 are closest to each other) will be referred to as the "lift-released state".

リフト解消状態において、上部固定部材３０は、中間部材２０の外側を覆うように配置される。即ち、上部固定部材３０の天板３１は、中間部材２０の天板２１の上方に配置され、上部固定部材３０の側板３２・３２は、中間部材２０の側板２２・２２の左右外側に配置される。
また、リフト解消状態において、中間部材２０の天板２１と上部固定部材３０の天板３１との間には所定の空間が形成される。当該空間は、後述する異物挟み防止部９０の遮蔽部材９１を収納する収納部９５として構成される。 In the lift-released state, the upper fixing member 30 is disposed so as to cover the outside of the intermediate member 20. That is, the top plate 31 of the upper fixing member 30 is disposed above the top plate 21 of the intermediate member 20, and the side plates 32, 32 of the upper fixing member 30 are disposed on the left and right outer sides of the side plates 22, 22 of the intermediate member 20.
In addition, in the lift-released state, a predetermined space is formed between the top plate 21 of the intermediate member 20 and the top plate 31 of the upper fixing member 30. The space is configured as a storage section 95 that stores a shielding member 91 of a foreign object pinching prevention section 90, which will be described later.

異物挟み防止部９０は、リフト状態において、中間部材２０及び上部固定部材３０の外側（ヒンジ１００の後方外側）から、中間部材２０と上部固定部材３０との間に異物（例えば工具や衣服や手指等）が入り込んで挟まることを防止する。
異物挟み防止部９０は、遮蔽部材９１と、取付け部材９３と、ガイド部材９４と、を備える。 In the lifted state, the foreign object pinch prevention section 90 prevents foreign objects (e.g., tools, clothing, fingers, etc.) from entering and becoming pinched between the intermediate member 20 and the upper fixing member 30 from the outside of the intermediate member 20 and the upper fixing member 30 (the rear outside of the hinge 100).
The foreign object pinching prevention unit 90 includes a shielding member 91 , an attachment member 93 , and a guide member 94 .

異物挟み防止部９０の遮蔽部材９１は、難燃性の比較的高い弾性変形可能な樹脂素材からなり、帯状に構成される。遮蔽部材９１の左右幅は、中間部材２０または上部固定部材３０の左右幅と略同一に構成される。遮蔽部材９１（遮蔽部材９１の一端部）は、上部固定部材３０（上部固定部材３０の後端部）に設けられる。 The shielding member 91 of the foreign object pinch prevention unit 90 is made of a resin material that is elastically deformable and has a relatively high flame retardancy, and is configured in a band shape. The left and right width of the shielding member 91 is configured to be approximately the same as the left and right width of the intermediate member 20 or the upper fixing member 30. The shielding member 91 (one end of the shielding member 91) is provided on the upper fixing member 30 (the rear end of the upper fixing member 30).

異物挟み防止部９０の遮蔽部材９１は、リフト状態とリフト解消状態とにおいてそれぞれ所定の配置態様となるように構成される。
リフト状態において、遮蔽部材９１の後部（少なくとも一部）は、上部固定部材３０における第二回動軸７２が配置される側と反対側の端部（上部固定部材３０の後端部）から下方に垂れ下がるようにして、上部固定部材３０の後端部から中間部材２０における第二回動軸７２が配置される側と反対側の端部（中間部材２０の後端部）に亘って配置される。このようにして、リフト状態において、中間部材２０及び上部固定部材３０の後方外側から見えないようにして、外側との空間を遮蔽するように構成される。また、リフト状態において、遮蔽部材９１の前部は、中間部材２０の天板２１の上方において、中間部材２０の後端部から前後中途部に亘って配置される。
リフト解消状態において、遮蔽部材９１は、収納部９５内（中間部材２０と上部固定部材３０との間）に収納するように配置される。 The shielding member 91 of the foreign object trapping prevention unit 90 is configured to assume a predetermined arrangement in each of the lifted state and the lift-released state.
In the lifted state, the rear portion (at least a part) of the shielding member 91 is arranged from the rear end of the upper fixing member 30 to the end of the intermediate member 20 opposite to the side where the second rotating shaft 72 is arranged (the rear end of the upper fixing member 30) so as to hang down downward from the end (the rear end of the upper fixing member 30) opposite to the side where the second rotating shaft 72 is arranged. In this way, in the lifted state, the shielding member 91 is configured to be invisible from the rear outside of the intermediate member 20 and the upper fixing member 30, and to shield the space with the outside. Also, in the lifted state, the front portion of the shielding member 91 is arranged above the top plate 21 of the intermediate member 20, from the rear end of the intermediate member 20 to the midway between the front and rear.
In the lift-released state, the shielding member 91 is arranged so as to be stored within the storage portion 95 (between the intermediate member 20 and the upper fixing member 30).

以上のように、異物挟み防止部９０の遮蔽部材９１は上部固定部材３０に設けられることから、連結対象物（複合機１の本体２または原稿圧着板３）へヒンジ１００を組付ける際に、原稿圧着板３から垂れ下がった異物挟み防止部９０が邪魔になってヒンジ１００の組付け作業が億劫になることを防止することができる。
したがって、ヒンジ１００によれば、異物挟み防止部９０を要する構成において、原稿圧着板３に異物挟み防止部９０が設けられるものに比べてヒンジ１００の組付け作業を比較的容易に行うことができる。 As described above, since the shielding member 91 of the foreign object pinch prevention section 90 is provided on the upper fixed member 30, when assembling the hinge 100 to the object to be connected (the main body 2 of the multifunction printer 1 or the original document pressing plate 3), it is possible to prevent the foreign object pinch prevention section 90 hanging down from the original document pressing plate 3 from getting in the way and making the assembling work of the hinge 100 tedious.
Therefore, in a configuration requiring the foreign object pinch prevention portion 90 , the hinge 100 can be assembled relatively easily compared to a configuration in which the foreign object pinch prevention portion 90 is provided on the original cover 3 .

ここで、ヒンジ１００は閉じた状態（リフト解消状態）で搬送されることが一般的である。
ヒンジ１００では、リフト解消状態において異物挟み防止部９０の遮蔽部材９１が収納部９５内に配置されることから、例えば、搬送時において、異物挟み防止部９０の遮蔽部材９１の他端部（上部固定部材３０に固定される側と反対側の端部）が突出した状態とならない。
したがって、ヒンジ１００によれば、異物挟み防止部９０（遮蔽部材９１）を備えるものであっても閉じた状態の構成が嵩張らないもの（コンパクトな構成）とすることができる。 Here, the hinge 100 is generally transported in a closed state (unlifted state).
In the hinge 100, when the lift is released, the shielding member 91 of the foreign object pinch prevention section 90 is positioned within the storage section 95, so that, for example, during transport, the other end (the end opposite the side fixed to the upper fixing member 30) of the shielding member 91 of the foreign object pinch prevention section 90 does not protrude.
Therefore, according to the hinge 100, even if the hinge 100 includes the foreign object pinching prevention portion 90 (shielding member 91), the configuration in the closed state can be made not bulky (compact configuration).

異物挟み防止部９０の取付け部材９３は、遮蔽部材９１を上部固定部材３０に取付けて固定する。取付け部材９３は、左右方向を長手方向とする平板状の部材である。
上部固定部材３０の天板３１の後端部は、後上方に突出するように折り曲げられて構成される。当該上部固定部材３０の天板３１の後端部の後面と、取付け部材９３とで、遮蔽部材９１の後端部（一端部）を挟み込むようにした状態で、ビス等によって取付け部材９３を上部固定部材３０の天板３１の後端部に固定することによって、遮蔽部材９１（遮蔽部材９１の一端部）を上部固定部材３０に取付ける。
取付け部材９３の左右幅は、上部固定部材３０または遮蔽部材９１の左右幅と略同一に構成される。取付け部材９３は、遮蔽部材９１の左右（遮蔽部材９１の短手方向側）に亘るように構成される。 The attachment member 93 of the foreign object pinching prevention portion 90 attaches and fixes the shielding member 91 to the upper fixing member 30. The attachment member 93 is a flat plate-shaped member whose longitudinal direction is the left-right direction.
The rear end of the top plate 31 of the upper fixing member 30 is bent so as to protrude rearward and upward. With the rear end (one end) of the shielding member 91 sandwiched between the rear surface of the rear end of the top plate 31 of the upper fixing member 30 and the mounting member 93, the mounting member 93 is fixed to the rear end of the top plate 31 of the upper fixing member 30 with a screw or the like, thereby mounting the shielding member 91 (one end of the shielding member 91) to the upper fixing member 30.
The left and right width of the attachment member 93 is configured to be approximately the same as the left and right width of the upper fixing member 30 or the shielding member 91. The attachment member 93 is configured to span across the left and right sides of the shielding member 91 (the short side sides of the shielding member 91).

このように、異物挟み防止部９０の取付け部材９３が遮蔽部材９１の左右に亘るように構成されることから、リフト解消状態からリフト状態にまたリフト状態からリフト解消状態に遮蔽部材９１の配置態様が変遷するとき、遮蔽部材９１が撓んだりまた反ること等を抑制することができる。 In this way, the attachment member 93 of the foreign object pinch prevention unit 90 is configured to extend across the left and right sides of the shielding member 91, so that when the arrangement of the shielding member 91 changes from the lift-released state to the lifted state and from the lifted state to the lift-released state, the shielding member 91 can be prevented from bending or warping.

異物挟み防止部９０のガイド部材９４は、リフト解消状態からリフト状態に遮蔽部材９１の配置態様が変遷するとき、また、リフト状態からリフト解消状態に遮蔽部材９１の配置態様が変遷するときに、遮蔽部材９１が円滑に移動するように、遮蔽部材９１を案内する。また、ガイド部材９４は、リフト解消状態からリフト状態に遮蔽部材９１の配置態様が変遷した際に、また、リフト状態からリフト解消状態に遮蔽部材９１の配置態様が変遷した際に、遮蔽部材９１が上述した所定の配置態様となっているように、遮蔽部材９１を案内する。 The guide member 94 of the foreign object pinch prevention unit 90 guides the shielding member 91 so that the shielding member 91 moves smoothly when the arrangement of the shielding member 91 changes from the lift-released state to the lifted state, and when the arrangement of the shielding member 91 changes from the lifted state to the lifted state. The guide member 94 also guides the shielding member 91 so that the shielding member 91 is in the above-mentioned predetermined arrangement when the arrangement of the shielding member 91 changes from the lift-released state to the lifted state, and when the arrangement of the shielding member 91 changes from the lifted state to the lifted state.

このように、異物挟み防止部９０のガイド部材９４が、リフト解消状態からリフト状態に遮蔽部材９１の配置態様が変遷した際に、また、リフト状態からリフト解消状態に遮蔽部材９１の配置態様が変遷した際に、遮蔽部材９１が上述した所定の配置態様となるように、遮蔽部材９１を案内することから、リフト解消状態からリフト状態またはリフト状態からリフト解消状態への遮蔽部材９１の配置態様の変遷を安定して行うことができる。 In this way, when the positioning state of the shielding member 91 changes from the lift-released state to the lifted state, or when the positioning state of the shielding member 91 changes from the lifted state to the lifted state, the guide member 94 of the foreign object pinch prevention unit 90 guides the shielding member 91 so that the shielding member 91 assumes the above-mentioned predetermined positioning state. This allows the positioning state of the shielding member 91 to be stably changed from the lift-released state to the lifted state or from the lifted state to the lift-released state.

異物挟み防止部９０のガイド部材９４は、棒状の部材であり、中間部材２０の側板２２・２２間に設けられ、中間部材２０の天板２１との間に若干の隙間（少なくとも遮蔽部材９１の厚みよりも大きい隙間）が形成されるように、中間部材２０の天板２１の上方に配置される。ガイド部材９４は、リフト解消状態において収納部９５内に配置される。
中間部材２０の側板２２・２２の後端部はそれぞれ上方（上部固定部材３０側）に突出するように形成され、当該側板２２・２２の突出する部分にはそれぞれ貫通孔が形成される。ガイド部材９４は、中間部材２０の側板２２・２２の貫通孔に挿通された状態で固定されて、中間部材２０の側板２２・２２間を渡るように配置される。
遮蔽部材９１は、遮蔽部材９１の前端部（他端部）が、ガイド部材９４の後方から中間部材２０の天板２１とガイド部材９４との間に挿通されて、中間部材２０の天板２１の上方において前方（第二回動軸７２側）に延出するように構成される。 The guide member 94 of the foreign object pinching prevention portion 90 is a rod-shaped member that is provided between the side plates 22, 22 of the intermediate member 20 and is disposed above the top plate 21 of the intermediate member 20 so that a slight gap (a gap that is at least larger than the thickness of the shielding member 91) is formed between the guide member 94 and the top plate 21 of the intermediate member 20. The guide member 94 is disposed in the storage portion 95 in the lift-released state.
The rear ends of the side plates 22 of the intermediate member 20 are formed so as to protrude upward (towards the upper fixed member 30), and a through hole is formed in each of the protruding portions of the side plates 22. The guide member 94 is fixed in a state in which it is inserted into the through hole of the side plates 22 of the intermediate member 20, and is disposed so as to span between the side plates 22 of the intermediate member 20.
The shielding member 91 is configured such that the front end (other end) of the shielding member 91 is inserted between the top plate 21 of the intermediate member 20 and the guide member 94 from behind the guide member 94, and extends forward (towards the second pivot shaft 72) above the top plate 21 of the intermediate member 20.

このように、異物挟み防止部９０のガイド部材９４は、中間部材２０の側板２２・２２間を渡るように配置され、中間部材２０の天板２１の上方に配置され、遮蔽部材９１は、遮蔽部材９１の他端部が、ガイド部材９４の後方から中間部材２０の天板２１とガイド部材９４との間に挿通されて、中間部材２０の天板２１の上方において第二回動軸７２側に延出するように構成されることから、前記遮蔽部材９１の配置態様が変遷した際に遮蔽部材９１が上述した所定の配置態様となるように遮蔽部材９１を案内する構成を、簡易な構成で実現することができる。 In this way, the guide member 94 of the foreign object pinch prevention unit 90 is disposed so as to span between the side plates 22, 22 of the intermediate member 20 and is disposed above the top plate 21 of the intermediate member 20, and the other end of the shielding member 91 is inserted between the top plate 21 of the intermediate member 20 and the guide member 94 from behind the guide member 94 and is configured to extend toward the second pivot shaft 72 above the top plate 21 of the intermediate member 20. This makes it possible to realize a simple configuration for guiding the shielding member 91 so that the shielding member 91 assumes the above-mentioned predetermined arrangement when the arrangement of the shielding member 91 changes.

異物挟み防止部９０の遮蔽部材９１は、切欠き部９２を備える。
遮蔽部材９１の切欠き部９２は、遮蔽部材９１の中央部を遮蔽部材９１の長手方向に沿って切り欠かれるように形成される。遮蔽部材９１の切欠き部９２は、遮蔽部材９１の左右中央において、遮蔽部材９１の後端部近傍から前端近傍に亘って形成される。
中間部材２０は、突出部２３を備える。
中間部材２０の突出部２３は、中間部材２０の天板２１の左右中央において、中間部材２０の天板２１の上面から上方に突出するように形成される。中間部材２０の突出部２３は、遮蔽部材９１の切欠き部９２に挿通される。
リフト解消状態からリフト状態またはリフト状態からリフト解消状態に遮蔽部材９１の配置態様が変遷する際には、中間部材２０の突出部２３の遮蔽部材９１の切欠き部９２に挿通される前後位置が変遷する。 The shielding member 91 of the foreign object trapping prevention unit 90 has a notch portion 92 .
The cutout portion 92 of the shielding member 91 is formed by cutting out the center of the shielding member 91 along the longitudinal direction of the shielding member 91. The cutout portion 92 of the shielding member 91 is formed in the left-right center of the shielding member 91, extending from near the rear end portion to near the front end portion of the shielding member 91.
The intermediate member 20 includes a protrusion 23 .
The protruding portion 23 of the intermediate member 20 is formed at the left-right center of the top plate 21 of the intermediate member 20 so as to protrude upward from the upper surface of the top plate 21 of the intermediate member 20. The protruding portion 23 of the intermediate member 20 is inserted into the notch portion 92 of the shielding member 91.
When the arrangement of the shielding member 91 transitions from the lift-released state to the lifted state or from the lifted state to the lift-released state, the front-rear position at which the protrusion 23 of the intermediate member 20 is inserted into the notch 92 of the shielding member 91 transitions.

このように、異物挟み防止部９０の遮蔽部材９１は切欠き部９２を備え、中間部材２０は遮蔽部材９１の切欠き部９２に挿通される突出部２３を備え、リフト解消状態からリフト状態またはリフト状態からリフト解消状態に遮蔽部材９１の配置態様が変遷する際には、中間部材２０の突出部２３の遮蔽部材９１の切欠き部９２に挿通される前後位置が変遷することから、リフト解消状態からリフト状態またはリフト状態からリフト解消状態に遮蔽部材９１の配置態様が変遷する際に、遮蔽部材９１が左右にずれることを防止することができる。したがって、リフト解消状態からリフト状態またはリフト状態からリフト解消状態への遮蔽部材９１の配置態様の変遷を安定して行うことができる。 In this way, the shielding member 91 of the foreign object pinching prevention unit 90 has a notch 92, and the intermediate member 20 has a protrusion 23 that is inserted into the notch 92 of the shielding member 91. When the arrangement of the shielding member 91 changes from the lift-released state to the lifted state or from the lifted state to the lift-released state, the front-to-rear position of the protrusion 23 of the intermediate member 20 that is inserted into the notch 92 of the shielding member 91 changes, so that when the arrangement of the shielding member 91 changes from the lift-released state to the lifted state or from the lifted state to the lift-released state, the shielding member 91 can be prevented from shifting left or right. Therefore, the arrangement of the shielding member 91 can be stably changed from the lift-released state to the lifted state or from the lifted state to the lift-released state.

なお、異物挟み防止部９０の遮蔽部材９１は、複数個の細長い部材が軸心方向に対して直交する方向に並べられた状態で連結されたすだれ状に構成して、リフト解消状態からリフト状態またはリフト状態からリフト解消状態へ配置態様が変遷するように構成することもできる。 The shielding member 91 of the foreign object pinch prevention unit 90 can also be configured in a blind shape with multiple elongated members connected in a line perpendicular to the axial direction, so that the arrangement can be changed from the lift-released state to the lifted state or from the lifted state to the lift-released state.

ヒンジ１００は、カバー部材８５を備える。
カバー部材８５は、一枚の金属板を適宜折り曲げることにより、前板、下板、及び一対の側板を備えるように形成される部材であり、第二スライダ５０に固定して設けられる。
カバー部材８５は、第二ウイング部材の内部が露出しないように（外側から見えないように）構成される。カバー部材８５は、第一スライダ４０、第二スライダ５０、バネ６０、ダンパー６２等が露出しないように、中間部材２０の前方の開口および下方の開口（第二ウイング部材の底面側）を覆うように構成される。カバー部材８５の前板は第一スライダ４０の前方に配置され、カバー部材８５の一対の側板は中間部材２０の側板２１・２１の左右外側に配置される。カバー部材８５の下板は、中間部材２０の下方の開口の下方、第一スライダ４０のカム当接部４２とカム部材７５との当接部分の下方、また、フェンス部材８０の下方に配置される。 The hinge 100 includes a cover member 85 .
The cover member 85 is a member that is formed by appropriately bending a single metal plate so as to have a front plate, a lower plate, and a pair of side plates, and is fixed to the second slider 50.
The cover member 85 is configured so that the inside of the second wing member is not exposed (not visible from the outside). The cover member 85 is configured to cover the front opening and the lower opening (the bottom side of the second wing member) of the intermediate member 20 so that the first slider 40, the second slider 50, the spring 60, the damper 62, etc. are not exposed. The front plate of the cover member 85 is disposed in front of the first slider 40, and the pair of side plates of the cover member 85 are disposed on the left and right outer sides of the side plates 21, 21 of the intermediate member 20. The lower plate of the cover member 85 is disposed below the lower opening of the intermediate member 20, below the abutment portion between the cam abutment portion 42 of the first slider 40 and the cam member 75, and below the fence member 80.

このように、カバー部材８５を備え、第二ウイング部材の内部が露出しないように中間部材２０の下方の開口等を覆うことから、ヒンジ１００の内部の樹脂素材等で構成される部材（第一スライダ４０等）の露出する部分を低減させて、ヒンジ１００を比較的難燃性の高い構成とすることができる。 In this way, the cover member 85 covers the lower opening of the intermediate member 20 so that the inside of the second wing member is not exposed, and this reduces the exposed portion of the members (such as the first slider 40) inside the hinge 100 that are made of a resin material or the like, making the hinge 100 relatively flame-retardant.

また、異物挟み防止部９０の遮蔽部材９１を比較的難燃性の高い素材で構成することもできる。このように構成することによって、ヒンジ１００を比較的難燃性の高い構成とすることができる。 The shielding member 91 of the foreign object trap prevention unit 90 can also be made of a material that is relatively flame-retardant. By configuring it in this way, the hinge 100 can be made to be relatively flame-retardant.

また、ヒンジ１００は、仕切部材７６を備える。
仕切部材７６は、下部固定部材１０（第一ウイング部材）内に配置され、下部固定部材１０内の空間を上下に仕切るように構成される。仕切部材７６は、カム部材７５及び第一回動軸７１が下方（第一ウイング部材と反対側）から見て露出しないように（下方から見えないように）構成される。
仕切部材７６は、左右一対の側板部７７・７７と、仕切部７８と、を備える。 The hinge 100 also includes a partition member 76 .
The partition member 76 is disposed within the lower fixed member 10 (first wing member) and is configured to divide the space within the lower fixed member 10 into upper and lower parts. The partition member 76 is configured so that the cam member 75 and the first rotating shaft 71 are not exposed (not visible from below) when viewed from below (the side opposite to the first wing member).
The partition member 76 includes a pair of left and right side plate portions 77 , 77 and a partition portion 78 .

仕切部材７６の一対の側板部７７・７７は、下部固定部材１０の一対の側板１１・１１の内側において一対の側板１１・１１に近接するようにそれぞれ配置される。仕切部材７６の側板部７７の前部には、カム部材７５を挿通するための貫通孔が開口され、仕切部材７６の側板部７７の後部には、第一回動軸７１を挿通するための貫通孔が開口される。仕切部材７６は、側板部７７の前部の貫通孔にカム部材７５が挿通され、側板部７７の後部の貫通孔に第一回動軸７１が挿通されて、下部固定部材１０（下部固定部材１０内）に固定される。 The pair of side plate portions 77, 77 of the partition member 76 are disposed so as to be adjacent to the pair of side plates 11, 11 on the inner side of the pair of side plates 11, 11 of the lower fixing member 10. A through hole for inserting the cam member 75 is opened in the front part of the side plate portion 77 of the partition member 76, and a through hole for inserting the first rotating shaft 71 is opened in the rear part of the side plate portion 77 of the partition member 76. The partition member 76 is fixed to the lower fixing member 10 (inside the lower fixing member 10) with the cam member 75 inserted in the through hole in the front part of the side plate portion 77 and the first rotating shaft 71 inserted in the through hole in the rear part of the side plate portion 77.

仕切部材７６の仕切部７８は、概ね板状に構成される。仕切部材７６の仕切部７８は、カム部材７５（カム部材７５の下部）から下部固定部材１０の背板１３（第一回動軸７１の下方）に亘るように配置される。また、仕切部材７６の仕切部７８は、下部固定部材１０の左右の側板１１・１１に亘って配置されて、一対の側板部７７・７７（側板部７７・７７の下部）を連結するように構成される。仕切部材７６の仕切部７８は、下部固定部材１０に取付けられた状態で、カム部材７５及び第一回動軸７１の下方に配置される。仕切部材７６の仕切部７８は、下部固定部材１０内において、カム部材７５及び第一回動軸７１が配置される側（上方側）とカム部材７５及び第一回動軸７１が配置される側と反対側（下方側）とを仕切る。カム部材７５及び第一回動軸７１が下方（第一ウイング部材と反対側）から見て露出しないように、カム部材７５及び第一回動軸７１等の下方に配置される。 The partition portion 78 of the partition member 76 is generally plate-shaped. The partition portion 78 of the partition member 76 is arranged so as to extend from the cam member 75 (the lower portion of the cam member 75) to the back plate 13 of the lower fixed member 10 (below the first pivot shaft 71). The partition portion 78 of the partition member 76 is also arranged across the left and right side plates 11 of the lower fixed member 10 and is configured to connect a pair of side plate portions 77 (lower portions of the side plate portions 77). The partition portion 78 of the partition member 76 is arranged below the cam member 75 and the first pivot shaft 71 when attached to the lower fixed member 10. The partition portion 78 of the partition member 76 divides the lower fixed member 10 into the side where the cam member 75 and the first pivot shaft 71 are arranged (upper side) and the side opposite to the side where the cam member 75 and the first pivot shaft 71 are arranged (lower side). The cam member 75 and the first pivot shaft 71 are positioned below the cam member 75 and the first pivot shaft 71 so that they are not exposed when viewed from below (the side opposite the first wing member).

このように、仕切部材７６の仕切部７８は、下部固定部材１０内に配置され、カム部材７５及び第一回動軸７１が下方（下部固定部材１０の底板１１側）から見て露出しないように構成される。
このため、ヒンジ１００の内部の露出する部分を低減させて、ヒンジ１００を比較的難燃性の高い構成とすることができる。 In this way, the partition portion 78 of the partition member 76 is disposed within the lower fixed member 10 and configured so that the cam member 75 and the first rotating shaft 71 are not exposed when viewed from below (the bottom plate 11 side of the lower fixed member 10).
Therefore, the exposed portion of the inside of the hinge 100 can be reduced, and the hinge 100 can be configured to have a relatively high flame retardancy.

図１０から図１３に示すように、仕切部材７６は、一枚の金属板に適宜折り曲げ加工を施すことにより、左右一対の側板部７７・７７と、側板部７７・７７を連結する仕切部７８と、を備えて構成することもできる。このとき、仕切部材７６の側板部７７と仕切り部７８とはそれぞれ平板状に構成される。
また図１１から図１３に示すように、第一スライダ４０のカム当接部４２は、第二ウイング部材の回動角度によらず、第二ウイング部材が閉状態から全開状態まで、カム部材７５に当接するように構成することもできる。 10 to 13, the partition member 76 can be formed by appropriately bending a single metal plate to include a pair of left and right side plate portions 77, 77 and a partition portion 78 connecting the side plate portions 77, 77. In this case, the side plate portions 77 and the partition portion 78 of the partition member 76 are each formed in a flat plate shape.
Also, as shown in Figures 11 to 13, the cam abutment portion 42 of the first slider 40 can be configured to abut against the cam member 75 from the closed state to the fully open state of the second wing member, regardless of the rotation angle of the second wing member.
