Then, the upper fixing member 30 is fixed to the original cover 3 so that 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（回動角度θ＝０°））とし、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」（原稿圧着板３が本体２に対して開いている状態（回動角度θ＝９０°））とする。 In the present 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 state where the document pressing plate 3 is closed with respect to the main body 2 (rotation angle θ = 0 °)), and the state in which the second wing member is farthest from the first wing member is the “open state” of the second wing member (the state where the document pressing plate 3 is open with respect to the main body 2 (rotation angle) θ = 90 °)).

バネ６０は金属製の巻きバネ（圧縮バネ）であり、本発明に係る付勢部材の実施の一形態である。バネ６０は中間部材２０の内部に収容される。 The spring 60 is a metal winding spring (compression spring), which is an embodiment of the biasing member according to the present invention. The spring 60 is accommodated in the intermediate member 20.

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 a 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 a 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ピン７３に接近する方向に付勢される。 Due to the urging force generated by the spring 60, that is, the force (elastic force) at which the spring 60 elastically deformed in the compression direction tries to return to its original shape (shape when no external force is acting). Is biased in a direction approaching the first rotation pin 71 in the longitudinal direction of the intermediate member 20, and the second slider 50 is biased in a direction approaching the pressure receiving pin 73 in the longitudinal direction of the intermediate member 20.

第二スライダ５０に形成されたバネ受け穴には、ダンパー６２が収容されている。ダンパー６２は、その先端部６２ａが第一回動ピン７１の側に突出するように配設されている。ダンパー６２は、第一スライダ４０のバネ受け穴に形成された押圧突起部４３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あり、ダンパー６２の本体部は第二スライダ５０の内部における所定の位置に固定される。 A damper 62 is accommodated in the spring receiving hole formed in the second slider 50. The damper 62 is disposed such that the tip end portion 62 a protrudes toward the first rotation pin 71. The damper 62 generates a reaction force when the tip end portion 62 a receives a pressing force by the pressing protrusion 43 formed in the spring receiving hole of the first slider 40. For this reason, the speed at which the first slider 40 moves due to the reaction force is reduced, and a buffering effect by the damper 62 is generated. The damper 62 is a general fluid damper, and the main body of the damper 62 is fixed at a predetermined position inside the second slider 50.

By forming the portion 163, the cam member 160 is formed as shown in FIG.

上側固定部１６１・１６１及び下側固定部１６２・１６２は、下部固定部材１１０において第一回動ピン７１を支持するそれぞれの側板１１２・１１２に着脱可能に係止される。具体的には、それぞれの上側固定部１６１・１６１には、内周部が略半円状に形成された第一係止部１６１ａ・１６１ａが形成されている。図５から図７に示す如く、第一係止部１６１ａ・１６１ａの内周形状は第一回動ピン７１の外周形状と略同径に形成されている。そして、第一係止部１６１ａ・１６１ａを第一回動ピン７１に係止することにより、上側固定部１６１・１６１が側板１１２・１１２に係止されるのである。 The upper fixing portions 161 and 161 and the lower fixing portions 162 and 162 are detachably locked to the side plates 112 and 112 that support the first rotation pin 71 in the lower fixing member 110. Specifically, first locking portions 161a and 161a each having an inner peripheral portion formed in a substantially semicircular shape are formed in the upper fixing portions 161 and 161, respectively. As shown in FIGS. 5 to 7, the inner peripheral shape of the first locking portions 161 a and 161 a is formed to have substantially the same diameter as the outer peripheral shape of the first rotation pin 71. Then, the upper fixing portions 161 and 161 are locked to the side plates 112 and 112 by locking the first locking portions 161 a and 161 a to the first rotation pin 71.

また、それぞれの下側固定部１６２・１６２には、内周部が半円状に、上側固定部１６１・１６１よりも小径に形成された第二係止部１６２ａ・１６２ａが形成されている。図５から図７に示す如く、第二係止部１６２ａ・１６２ａの内周形状は側板１１２・１１２から突出する係止部１１２ａの外周形状と略同径に形成されている。そして、第二係止部１６２ａ・１６２ａを係止部１１２ａに係止することにより、下側固定部１６２・１６２が側板１１２・１１２に係止されるのである。 The lower fixing portions 162 and 162 are respectively formed with second locking portions 162a and 162a whose inner peripheral portions are semicircular and whose diameter is smaller than that of the upper fixing portions 161 and 161. As shown in FIGS. 5 to 7, the inner peripheral shape of the second locking portions 162 a and 162 a is formed to have substantially the same diameter as the outer peripheral shape of the locking portion 112 a protruding from the side plates 112 and 112. The lower fixing portions 162 and 162 are locked to the side plates 112 and 112 by locking the second locking portions 162a and 162a to the locking portions 112a.

上記の如く、第一係止部１６１ａ・１６１ａ及び第二係止部１６２ａ・１６２ａはそれぞれ、略半円状に形成されている。そして、第一係止部１６１ａ・１６１ａ及び第二係止部１６２ａ・１６２ａを第一回動ピン７１及び係止部１１２ａに係止する構成であるため、カム部材１６０は下部固定部材１１０に対して容易に着脱することができる。 As described above, the first locking portions 161a and 161a and the second locking portions 162a and 162a are each formed in a substantially semicircular shape. And since it is the structure which latches the 1st latching | locking part 161a * 161a and the 2nd latching | locking part 162a * 162a to the 1st rotation pin 71 and the latching | locking part 112a, the cam member 160 is with respect to the lower fixing member 110. Can be easily attached and detached.

本実施形態においては、カム部材１６０を下部固定部材１１０に取付けた状態において、下側固定部１６２における側板１１２の固定孔１１２ｂと同じ位置となるように、固定孔１６２ｂが開口されている。そして、固定孔１１２ｂと固定孔１６２ｂとに図示しないボルト等の固定具を挿通し、ナット等で締結することにより、カム部材１６０を下部固定部材１１０に対して堅固に固定することができる。 In the present embodiment, when the cam member 160 is attached to the lower fixing member 110, the fixing hole 162 b is opened so as to be in the same position as the fixing hole 112 b of the side plate 112 in the lower fixing portion 162. The cam member 160 can be firmly fixed to the lower fixing member 110 by inserting a fixing tool such as a bolt (not shown) through the fixing hole 112b and the fixing hole 162b and fastening with a nut or the like.

カム部材１６０を下部固定部材１１０に対して取付けた際には、図５から図７に示す如く、曲板部１６３は前方（本実施形態における第二回動ピン７２の側）に向かうように配設される。換言すれば、曲板部１６３は、第二ウイング部材が閉状態である際の第一スライダ４０部材の側が凸形状となるように、第一回動ピン７１と平行な軸回りに屈曲されているのである。 When the cam member 160 is attached to the lower fixing member 110, as shown in FIGS. 5 to 7, the curved plate portion 163 is directed forward (to the side of the second rotation pin 72 in the present embodiment). Arranged. In other words, the curved plate portion 163 is bent around an axis parallel to the first rotation pin 71 so that the first slider 40 member side has a convex shape when the second wing member is in the closed state. It is.

カム部材１６０を下部固定部材１１０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４１はカム部材１６０の曲板部１６３に当接するとともに、第二スライダ５０が受圧ピン７３の外周面に当接する。 When the cam member 160 is attached to the lower fixing member 110 and the second wing member is in the closed state, the cam contact surface 41 of the first slider 40 contacts the curved plate portion 163 of the cam member 160 and the second The slider 50 contacts the outer peripheral surface of the pressure receiving pin 73.

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（ひいては本発明に係る第二ウイング部材の実施の一形態）は下部固定部材１１０に対して開く方向（本実施形態では、右側面視で反時計回りとなる方向）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（本実施形態では、右側面視で反時計回りとなる方向）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は第一スライダ４０の押圧突起部４３によって押圧され、本体部の側に押し込まれる。 As a result, due to the elastic force generated in the spring 60, the intermediate member 20 (and thus one embodiment of the second wing member according to the present invention) opens with respect to the lower fixing member 110 (in this embodiment, as viewed from the right side). The upper fixing member 30 is biased so as to rotate counterclockwise (in the counterclockwise direction), and the upper fixing member 30 rotates in the direction closing with respect to the intermediate member 20 (in the present embodiment, the counterclockwise direction when viewed from the right side). It is energized to move. At this time, the tip 62a of the damper 62 is pressed by the pressing protrusion 43 of the first slider 40 and is pushed into the main body.

本実施形態では、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°からφ°までの範囲にあるとき（０°≦θ≦φ°のとき）、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（中間部材２０を下部固定部材１１０に対して右側面視で時計回りに回動させようとする回転力）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（中間部材２０を下部固定部材１１０に対して右側面視で反時計回りに回動させようとする回転力）と、が概ね平衡するように、第一スライダ４０のカム当接面４１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°からφ°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, when the rotation angle θ of the original cover 3 with respect to the main body 2 of the multifunction machine 1 is in the range from 0 ° to φ ° (when 0 ° ≦ θ ≦ φ °), the upper fixing member 30 Rotational force for closing the hinge 100 due to the weight of the fixed original cover 3 (rotational force for rotating the intermediate member 20 clockwise relative to the lower fixing member 110). And a rotational force for opening the hinge 100 due to the biasing force of the spring 60 (a rotational force for rotating the intermediate member 20 counterclockwise with respect to the lower fixing member 110 in a right side view). The shape of the cam contact surface 41 of the first slider 40 and the like are determined in advance so as to be substantially balanced.
With this configuration, when the operator releases his or her hand from the original pressure plate 3 when the rotation angle θ of the original pressure plate 3 with respect to the main body 2 of the multifunction machine 1 is in the range of 0 ° to φ °, The rotation angle θ is maintained.

また、本実施形態では、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φ°から９０°までの範囲にあるとき（φ°＜θ≦９０°のとき）、第一スライダ４０の回動ピン支持面４２が第一回動ピン７１の外周面に当接し、第一スライダ４０がカム部材１６０に接近する方向に移動することが規制されるとともに、第一スライダ４０のカム当接面４１がカム部材１６０の曲板部１６３から離間する。
本実施形態の第一回動ピン７１の軸線方向に垂直な面における断面形状は円形であるため、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φ°から９０°までの範囲で変化しても、（厳密には中間部材２０に対する上部固定部材３０の回動角度が変化しない限りにおいて）中間部材２０に対する第一スライダ４０の位置、ひいてはバネ６０の全長（バネ６０が発生する付勢力）は変化しない。 In this embodiment, when the rotation angle θ of the original cover 3 with respect to the main body 2 of the multifunction machine 1 is in the range from φ ° to 90 ° (when φ ° <θ ≦ 90 °), the first slider The rotation pin support surface 42 of the 40 abuts against the outer peripheral surface of the first rotation pin 71, and the movement of the first slider 40 in the direction approaching the cam member 160 is restricted, and the cam of the first slider 40 The contact surface 41 is separated from the curved plate portion 163 of the cam member 160.
Since the cross-sectional shape of the first rotation pin 71 of the present embodiment in the plane perpendicular to the axial direction is circular, the rotation angle θ of the original cover 3 with respect to the main body 2 of the multifunction machine 1 is from φ ° to 90 °. Even if the range changes, the position of the first slider 40 with respect to the intermediate member 20 and, consequently, the entire length of the spring 60 (strictly, as long as the rotation angle of the upper fixing member 30 with respect to the intermediate member 20 does not change) The urging force) does not change.

従って、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φ°から９０°までの範囲にあるときには、（厳密にはバネ６０の付勢力に起因して第一スライダ４０の回動ピン支持面４２と第一回動ピン７１の外周面との当接部分には摩擦力が作用するが）実質的にはバネ６０の付勢力が第一スライダ４０を介してカム部材１６０に作用しなくなり、ひいてはバネ６０の付勢力に起因してヒンジ１００を開こうとする回転力（中間部材２０を下部固定部材１１０に対して右側面視で反時計回りに回動させようとする回転力）がヒンジ１００に作用しなくなる。
なお、φの値は後述するカム部材１６０によるバネ６０の付勢力の調整の結果、多少変動する場合がある。 Therefore, when the rotation angle θ of the original cover 3 with respect to the main body 2 of the multifunction device 1 is in the range from φ ° to 90 ° (strictly speaking, the rotation of the first slider 40 is caused by the biasing force of the spring 60). (Although a frictional force acts on the contact portion between the moving pin support surface 42 and the outer peripheral surface of the first rotation pin 71), the urging force of the spring 60 is substantially applied to the cam member 160 via the first slider 40. Rotational force that causes the hinge 100 to open due to the urging force of the spring 60 (which rotates the intermediate member 20 to rotate counterclockwise with respect to the lower fixing member 110 in the right side view). Force) does not act on the hinge 100.
Note that the value of φ may slightly vary as a result of adjustment of the biasing force of the spring 60 by the cam member 160 described later.

本実施形態に係るヒンジ１００によれば、カム部材１６０を別形状のカム部材に付け替えることにより、バネ６０の付勢力を調整することができる。即ち、本体２と原稿圧着板３との連結状態を維持したままで、第一スライダ４０がカム部材に当接する位置を変更可能とし、バネ６０を交換するといった作業を伴わずにバネ６０の付勢力を調整できる。 According to the hinge 100 according to the present embodiment, the urging force of the spring 60 can be adjusted by replacing the cam member 160 with a cam member having a different shape. That is, the position at which the first slider 40 abuts the cam member can be changed while maintaining the connected state of the main body 2 and the original cover 3, and the spring 60 can be attached without replacing the spring 60. You can adjust the power.

Then, the first contact portions 151 and 151 and the second contact portion 152 are fixed to the fixing portion 123 while the fixing portion 123 is sandwiched between the first contact portions 151 and 151 and the second contact portion 152 of the fixing member 150. (The fixed part 123 is inserted between the first contact parts 151 and 151 and the second contact part 152). When the fixing member 150 is further moved downward, the pin portion 155 of the pin indicating portion 154 is pressed by the fixing portion 123, and the pin indicating portion 154 is elastically deformed to the right side. Thereafter, as shown in FIGS. 13A and 13B, the pin portion 155 is inserted into the insertion hole 123a of the fixing portion 123, and the pin instruction portion 154 returns to its original state. Thereby, the fixing member 150 is attached to the fixing portion 123 by the pin portion 155 engaging with the insertion hole 123a.

固定部材１５０が固定部１２３に装着された際には、図１３（ａ）及び（ｂ）に示す如く、第一当接部１５１・１５１と第二当接部１５２の先端部が、長孔１１１ｂに挿入される。この際、第二当接部１５２のストッパ部１５２ａ・１５２ａは底板１１１に当接する。本実施形態において、固定部１２３の板厚と、長孔１１１ｂに挿入される第一当接部１５１・１５１と第二当接部１５２の先端部との先端部の板厚と、の合計の厚さは、長孔１１１ｂの所定幅ｄと等しくなるように形成される。 When the fixing member 150 is attached to the fixing portion 123, as shown in FIGS. 13A and 13B, the leading end portions of the first contact portions 151 and 151 and the second contact portion 152 are elongated holes. It is inserted into 111b. At this time, the stopper portions 152 a and 152 a of the second contact portion 152 are in contact with the bottom plate 111. In the present embodiment, the total of the plate thickness of the fixing portion 123 and the plate thickness of the tip portion of the first contact portions 151 and 151 inserted into the long hole 111b and the tip portion of the second contact portion 152 is The thickness is formed to be equal to the predetermined width d of the long hole 111b.

本実施形態に係るヒンジ１００によれば上記の如く、長孔１１１ｂの所定幅ｄを、固定部１２３、第一当接部１５１・１５１、及び、第二当接部１５２で充足する構成としている。これにより、長孔１１１ｂの所定幅ｄの方向に隙間が生じなくしている。このため、固定具１２０と下部固定部材１１０との間でがたつきを防止することができる。即ち、固定具１２０と下部固定部材１１０とをビス等で連結する際に、固定具１２０の固定孔１２４と下部固定部材１１０の固定長孔１１１ｄとの位置合わせが容易となる。 According to the hinge 100 according to the present embodiment, as described above, the predetermined width d of the long hole 111b is satisfied by the fixing portion 123, the first contact portions 151 and 151, and the second contact portion 152. . This prevents a gap from occurring in the direction of the predetermined width d of the long hole 111b. For this reason, rattling between the fixture 120 and the lower fixing member 110 can be prevented. That is, when the fixing tool 120 and the lower fixing member 110 are connected with a screw or the like, the positioning of the fixing hole 124 of the fixing tool 120 and the fixing long hole 111d of the lower fixing member 110 is facilitated.

なお、本実施形態においては、第一当接部１５１・１５１と第二当接部１５２との双方の先端部が長孔１１１ｂに挿入される構成としたが、長孔１１１ｂの所定幅ｄが充足される構成であれば、第一当接部１５１・１５１と第二当接部１５２とのうち何れか一方の先端部が長孔１１１ｂに挿入される構成としても差し支えない。 In addition, in this embodiment, although it was set as the structure by which both front-end | tip parts of the 1st contact part 151 * 151 and the 2nd contact part 152 were inserted in the long hole 111b, the predetermined width | variety d of the long hole 111b is set. As long as the configuration is satisfied, any one of the first contact portions 151 and 151 and the second contact portion 152 may be inserted into the long hole 111b.

また、本実施形態においては、作業者が手作業で固定部材１５０を用いて下部固定部材１１０を固定板部１２１に対して固定することができるため、作業効率が向上する。また、金属製の圧入ピンではなく、樹脂製の固定部材１５０を用いているため、ヒンジ１００を軽量化することができる。また、挿通孔１２３ａに対してピン部１５５が水平方向に挿入される構成であるため、輸送時等の振動によって固定部材１５０が脱落することを防止できる。 Moreover, in this embodiment, since the operator can fix the lower fixing member 110 to the fixing plate portion 121 by using the fixing member 150 manually, the working efficiency is improved. Further, since the resin fixing member 150 is used instead of the metal press-fit pin, the weight of the hinge 100 can be reduced. In addition, since the pin portion 155 is inserted in the horizontal direction with respect to the insertion hole 123a, it is possible to prevent the fixing member 150 from falling off due to vibration during transportation.

また、本実施形態に係るヒンジ１００によれば、固定孔１２２ａに対する固定ボルト１４１の螺入長さを調節することにより、固定板部１２１及び本体２に対する下部固定部材１１０の前後位置を調節可能としている。この際、固定部１２３が長孔１１１ｂに沿って移動することにより、下部固定部材１１０と固定具１２０とが相対変位可能とされる。また、長孔１１１ｂにおける左側の長辺の近傍には、長手方向である前後方向に沿って目盛１１１ｃが形成されている。そして、下部固定部材１１０と固定具１２０とが相対変位した際に、ピン支持部１５４の左側面に形成された指示部１５６が目盛１１１ｃに沿って変位する。 Further, according to the hinge 100 according to the present embodiment, the front and rear positions of the lower fixing member 110 with respect to the fixing plate portion 121 and the main body 2 can be adjusted by adjusting the screwing length of the fixing bolt 141 into the fixing hole 122a. Yes. At this time, the fixing portion 123 moves along the long hole 111b, so that the lower fixing member 110 and the fixture 120 can be relatively displaced. Further, in the vicinity of the left long side of the long hole 111b, a scale 111c is formed along the longitudinal direction which is the longitudinal direction. Then, when the lower fixing member 110 and the fixing tool 120 are relatively displaced, the instruction portion 156 formed on the left side surface of the pin support portion 154 is displaced along the scale 111c.

上記の如く本実施形態に係るヒンジ１００においては、指示部１５６と目盛１１１ｃとの位置関係を用いて、固定板部１２１及び本体２に対する下部固定部材１１０の前後位置を調節することができる。なお、本実施形態において、支持部１５６はピン指示部１５４に形成したが、ピン支持部を第一当接部１５１又は第二当接部１５２に形成する構成とすることも可能である。 As described above, in the hinge 100 according to the present embodiment, the front-rear position of the lower fixing member 110 with respect to the fixing plate 121 and the main body 2 can be adjusted using the positional relationship between the instruction unit 156 and the scale 111c. In the present embodiment, the support portion 156 is formed on the pin instruction portion 154. However, the pin support portion may be formed on the first contact portion 151 or the second contact portion 152.
