In other words, one embodiment of the second wing member according to the present invention includes an intermediate member 20, an upper fixing member 30, a first slider 40, a second slider 50, a second rotating pin 72, and a pressure receiving portion 73. .. Then, the upper fixing member 30 is fixed to the document crimping plate 3, so that the second wing member is fixed to the second connecting 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。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。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 the present embodiment, the state in which the second wing member is closest to the first wing member is defined as the "closed state" of the second wing member (the state in which the document crimping plate 3 is closed with respect to the main body 2). The closed state refers to a state in which the rotation angle θ of the second wing member with respect to the first wing member from the closed state is 0 degrees. Further, the state in which the second wing member is most distant from the first wing member is defined as the "open state" of the second wing member. The open state refers to a state in which the document crimping plate 3 is open with respect to the main body 2 and a rotation angle θ of 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 an embodiment of an urging member, and is composed of a metal wound spring (compression spring). The spring 60 is housed inside the intermediate member 20 (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 portion of the spring 60 is inserted into the spring receiving hole formed in the first slider 40 and comes into contact with the bottom surface of the spring receiving hole. Further, the front end portion of the spring 60 is inserted into the spring receiving hole formed in the second slider 50 and comes into contact with 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ピン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 first slider 40 is due to the urging force generated by the spring 60, that is, the force (elastic force) that causes the spring 60 elastically deformed in the direction of compression to return to its original shape (shape when no external force is applied). Is urged in the longitudinal direction of the intermediate member 20 in the direction approaching the first rotation pin 71, and the second slider 50 is urged in the longitudinal direction of the intermediate member 20 in the 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６２ａが第一回動ピン７１の側に突出する。ダンパー６２は、第一スライダ４０の底部によって先端部６２ａ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 62a projects toward the first rotation pin 71. The damper 62 generates a reaction force when the tip portion 62a is pressed by the bottom portion of the first slider 40. Therefore, the reaction force reduces the speed at which the first slider 40 moves, and the damper 62 produces a cushioning effect. The damper 62 is composed of a general fluid damper.

カム部材８０は樹脂材料からなる。カム部材８０は下部固定部材１０の背板１３に固定される。カム部材８０の上後部に形成された貫通孔には、第一回動ピンが挿通される。カム部材８０の上後部には、第一スライダ４０のカム当接面４３に当接するカム面８１が形成されている。 The cam member 80 is made of a resin material. The cam member 80 is fixed to the back plate 13 of the lower fixing member 10. The first rotation pin is inserted into the through hole formed in the upper rear portion of the cam member 80. A cam surface 81 that contacts the cam contact surface 43 of the first slider 40 is formed on the upper rear portion of the cam member 80.

カム部材８０を下部固定部材１０に取付け、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のカム当接面４３はカム部材８０のカム面８１に当接するとともに、第二スライダ５０のカム当接面５２が受圧部７３に当接する。
その結果として、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６２ａは第二スライダ５０の底部によって押圧され、本体部側に押し込まれる。 When the cam member 80 is attached to the lower fixing member 10 and the second wing member is closed, the cam contact surface 43 of the first slider 40 comes into contact with the cam surface 81 of the cam member 80, and the second slider The cam contact surface 52 of 50 comes into contact with the pressure receiving portion 73.
As a result, the elastic force generated in the spring 60 urges the intermediate member 20 (second wing member) to rotate in the opening direction with respect to the lower fixing member 10, and the upper fixing member 30 is urged to the intermediate member 20. On the other hand, it is urged to rotate in the closing direction. At this time, the tip portion 62a of the damper 62 is pressed by the bottom portion of the second slider 50 and pushed toward the main body portion.

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 the present embodiment, when the rotation angle θ of the second wing member with respect to the first wing member from the closed state is in the first region from 0 degree to the first predetermined angle φ1 (when 0 degree ≤ θ ≤ φ1). ), The elastic force generated in the spring 60 causes the second wing member to rotate in the open state with respect to 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). The first predetermined angle φ1 can 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のカム当接面４３またはカム部材８０のカム面８１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 the present embodiment, the rotational force for closing the hinge 100 due to the weight of the original crimping plate 3 fixed to the upper fixing member 30 and the urging force for the spring 60 to open the hinge 100. The shape of the cam contact surface 43 of the first slider 40 or the cam surface 81 of the cam member 80 is predetermined so that the rotational force to be applied is substantially balanced.
With this configuration, when the operator releases his / her hand from the original crimping plate 3 in the range where the rotation angle θ of the original crimping plate 3 with respect to the main body 2 of the multifunction device 1 is in the range of 0 degrees to φ1, the rotation is performed. The moving angle θ is maintained.

フェンス部材９０は、カム部材８０のカム面８１の近傍において、カム部材８０のカム面８１及び第一スライダ４０のカム当接面４３の前方に配置される（図７参照）。フェンス部材９０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８０の外側から、第一スライダ４０のカム当接面４３とカム部材８０のカム面８１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９０は、カム部材８０のカム面８１（第一スライダ４０のカム当接面４３とカム部材８０のカム面８１との当接部分）を前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。
フェンス部材９０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９０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 90 is arranged in the vicinity of the cam surface 81 of the cam member 80 in front of the cam surface 81 of the cam member 80 and the cam contact surface 43 of the first slider 40 (see FIG. 7). The fence member 90 comes into contact with the cam of the first slider 40 from the outside of the first slider 40 and the cam member 80 from the closed state to the open state of the intermediate member 20 (over the entire rotation range of the intermediate member 20). It prevents foreign matter (for example, a document) from entering the contact portion side between the surface 43 and the cam surface 81 of the cam member 80. The fence member 90 makes the cam surface 81 of the cam member 80 (the contact portion between the cam contact surface 43 of the first slider 40 and the cam surface 81 of the cam member 80) invisible from the front outside so that it can be seen from the outside. It is configured to shield the space.
The fence member 90 is supported (rotatably) so as to hang from the first slider 40 (cam contact portion 42). The fence member 90 is configured to be movable along with the rotation operation of the intermediate member 20 or the movement operation of the first slider 40.

フェンス部材９０は、本体部９１と、一対のアーム９２と、を具備する（図９参照）。
本体部９１は、カム部材８０（カム面８１）の左右幅と略同一の板状に構成される。
アーム９２は、本体部９１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９２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９３・９３を有する。 The fence member 90 includes a main body 91 and a pair of arms 92 (see FIG. 9).
The main body 91 is formed in a plate shape substantially the same as the left-right width of the cam member 80 (cam surface 81).
The arm 92 projects outward from the left and right upper ends of the main body 91, and further projects upward. The arm 92 has convex portions 93 and 93 projecting inward in the left-right direction at an end portion on the projecting side above the arm 92.

第一スライダ４０は、凹部４４と、案内部４５と、を具備する（図８参照）。
凹部４４は、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形成される略半球状の凹状の切欠きである。左右の凹部４４にフェンス部材９０の左右の凸部９３がそれぞれ配置されることによって、フェンス部材９０が第一スライダ４０（カム当接部４２）に支持される。
案内部４５は、第一スライダ４０のカム当接部４２の左右の側面に形成される溝（貫通溝）である。案内部４５は、カム当接部４２の側面を後上端部から凹部４４まで切欠くように形成される。案内部４５は、フェンス部材９０を第一スライダ４０に取付けるときに、フェンス部材９０の凸部９３が第一スライダ４０の案内部４５を通って凹部４４に至るようにすることから、凸部９３を凹部４４に配置し易くする。 The first slider 40 includes a recess 44 and a guide portion 45 (see FIG. 8).
The recess 44 is a substantially hemispherical concave notch formed in a substantially central portion of the left and right side surfaces of the cam contact portion 42 of the first slider 40. The fence member 90 is supported by the first slider 40 (cam contact portion 42) by arranging the left and right convex portions 93 of the fence member 90 in the left and right concave portions 44, respectively.
The guide portion 45 is a groove (through groove) formed on the left and right side surfaces of the cam contact portion 42 of the first slider 40. The guide portion 45 is formed so as to cut out the side surface of the cam contact portion 42 from the rear upper end portion to the recess 44. When the fence member 90 is attached to the first slider 40, the guide portion 45 causes the convex portion 93 of the fence member 90 to pass through the guide portion 45 of the first slider 40 to reach the concave portion 44, so that the convex portion 93 Is easy to arrange in the recess 44.

このように、フェンス部材９０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８０のカム面８１近傍においてカム部材８０のカム面８１及び第一スライダ４０のカム当接面４３との前方（カム部材８０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８０の外側から、第一スライダ４０のカム当接面４３とカム部材８０のカム面８１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のカム当接面４３とカム部材８０のカム面８１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９０は、第一スライダ４０に支持されて、第一スライダ４０のカム当接面４３とカム部材８０のカム面８１との当接部分を前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ことから、カム部材８０のカム面８１が極力露出しないこととなり、カム部材８０側からオイルが外側に飛散することを抑制することができる。
また、フェンス部材９０は、第一スライダ４０に支持され、中間部材２０の回動動作または第一スライダ４０移動動作とともに移動可能に構成されることから、異物が第一スライダ４０のカム当接面４３とカム部材８０のカム面８１との当接部分側に入り込むことをより確実に防止することができる。 In this way, the fence member 90 is supported so as to hang from the first slider 40, and is brought into contact with the cam surface 81 of the cam member 80 and the cam contact surface 43 of the first slider 40 in the vicinity of the cam surface 81 of the cam member 80. It is arranged in front (in front of the contact portion between the cam member 80 and the first slider 40), and from the outside of the first slider 40 and the cam member 80, the cam contact surface 43 of the first slider 40 and the cam surface of the cam member 80. In order to prevent foreign matter (for example, a document) from entering the contact portion with the 81, the document placed on the upper surface of the main body 2 from the closed state to the open state of the second wing member is the first slider. It is possible to reliably prevent oil from adhering to the original by entering the contact portion side between the cam contact surface 43 of 40 and the cam surface 81 of the cam member 80.
Further, the fence member 90 is supported by the first slider 40 so that the contact portion between the cam contact surface 43 of the first slider 40 and the cam surface 81 of the cam member 80 cannot be seen from the front outside so as to be visible from the outside. Since the cam surface 81 of the cam member 80 is not exposed as much as possible because it is configured to shield the space of the cam member 80, it is possible to suppress the oil from scattering to the outside from the cam member 80 side.
Further, since the fence member 90 is supported by the first slider 40 and is configured to be movable together with the rotation operation of the intermediate member 20 or the movement operation of the first slider 40, foreign matter can be moved to the cam contact surface of the first slider 40. It is possible to more reliably prevent the cam member 80 from entering the contact portion side with the cam surface 81 of the cam member 80.

フェンス部材９０の本体部９１は、上下中央部が前方に突出するように緩やかに湾曲する弧状に形成されつつ、下端部が後方（カム部材８０側）に突出するように構成される。
このように構成することによって、中間部材２０の閉状態から開状態まで、第一スライダ４０及びカム部材８０の外側から、第一スライダ４０のカム当接面４３とカム部材８０のカム面８１との当接部分側に異物が入り込むことをより確実に防止することができる。
なお、フェンス部材９０の本体部９１は、第一スライダ４０のカム当接面４３とカム部材８０のカム面８１との当接部分側に異物が入り込むことをより確実に防止するにあたって、このように湾曲する等の構成以外に角張るように構成することもできる。 The main body 91 of the fence member 90 is formed so that the lower end thereof protrudes rearward (toward the cam member 80) while the upper and lower central portions are formed in an arc shape that gently curves so as to protrude forward.
With this configuration, from the closed state to the open state of the intermediate member 20, from the outside of the first slider 40 and the cam member 80, the cam contact surface 43 of the first slider 40 and the cam surface 81 of the cam member 80 It is possible to more reliably prevent foreign matter from entering the contact portion side of the.
In addition, the main body 91 of the fence member 90 can more reliably prevent foreign matter from entering the contact portion side between the cam contact surface 43 of the first slider 40 and the cam surface 81 of the cam member 80. In addition to the configuration such as being curved to, it can also be configured to be angular.

フェンス部材９０の本体部９１は、左右一対のガード部９４・９４を有する。
ガード部９４は、フェンス部材９０の本体部９１の内側（後面）に溜まったグリスや塵芥等が本体部９１の外側（左右外側）に漏出すことを防止する。ガード部９４は、本体部９１の後面（カム部材８０側の面）左右縁部近傍に設けられる。ガード部９４は、本体部９１の上端部近傍から下端部近傍に亘って上下方向に形成される突条に構成される。
このように構成することによって、フェンス部材９０の本体部９１の内側に溜まったグリス等が本体部９１の外側に漏出すことを防止するものを簡易な構成で実現することができる。 The main body 91 of the fence member 90 has a pair of left and right guard portions 94 and 94.
The guard portion 94 prevents grease and dust accumulated on the inside (rear surface) of the main body portion 91 of the fence member 90 from leaking to the outside (left and right outside) of the main body portion 91. The guard portion 94 is provided near the left and right edges of the rear surface (the surface on the cam member 80 side) of the main body portion 91. The guard portion 94 is formed of a ridge formed in the vertical direction from the vicinity of the upper end portion to the vicinity of the lower end portion of the main body portion 91.
With this configuration, it is possible to realize a simple configuration that prevents grease and the like accumulated inside the main body 91 of the fence member 90 from leaking to the outside of the main body 91.

なお、フェンス部材９０が、第一スライダ４０にぶら下がるように支持される構成はこのような構成に限定されるものではない。例えば、フェンス部材９０のアーム９２が凸部９３を有さずに凹部を有し、第一スライダ４０が凹部４４を有さずに凸部を有し、フェンス部材９０の凹部に第一スライダ４０の凸部が配置されることによって、フェンス部材９０が第一スライダ４０に支持される構成とすることもできる。また例えば、フェンス部材９０が第一スライダ４０の本体４１に支持される構成とすることもできる。 The configuration in which the fence member 90 is supported so as to hang from the first slider 40 is not limited to such a configuration. For example, the arm 92 of the fence member 90 has a concave portion without having a convex portion 93, the first slider 40 has a convex portion without having a concave portion 44, and the first slider 40 has a concave portion in the concave portion of the fence member 90. By arranging the convex portion of the fence member 90, the fence member 90 can be supported by the first slider 40. Further, for example, the fence member 90 may be supported by the main body 41 of the first slider 40.
