なお、図示せぬＥリングが第一回動ピン７１の外周面の両端部に嵌装されることにより、第一回動ピン７１は中間部材２０および下部固定部材１１０から脱落しない。 The first rotation pin 71 is inserted through a through hole formed in the intermediate member 20 and a through hole of the bearing 74 fitted to the side plate 112 of the lower fixing member 110. The intermediate member 20 is rotatably connected to the lower fixing member 110 via the first rotation pin 71.
The E-ring (not shown) is fitted to both end portions of the outer peripheral surface of the first rotation pin 71 so that the first rotation pin 71 does not fall off from the intermediate member 20 and the lower fixing member 110.

上部固定部材３０は一枚の金属板を適宜折り曲げることにより、天板及び二枚の側板で形成される略筒状の部材である。上部固定部材３０は後述する如く第二回動ピン７２を介して中間部材２０に回動可能に支持される。また、上部固定部材３０は原稿圧着板３に固定されている。上部固定部材３０の上面には調節ねじ３１が螺入されており、調節ねじ３１を螺入する長さを調節することにより、上部固定部材３０の中間部材２０に対する位置を調節することができる。 The upper fixing member 30 is a substantially cylindrical member formed of a top plate and two side plates by appropriately bending a single metal plate. The upper fixing member 30 is rotatably supported by the intermediate member 20 via a second rotation pin 72 as will be described later. The upper fixing member 30 is fixed to the original cover 3. An adjustment screw 31 is screwed into the upper surface of the upper fixing member 30, and the position of the upper fixing member 30 relative to the intermediate member 20 can be adjusted by adjusting the length of the adjustment screw 31.

第二回動ピン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。第二回動ピン７２は一対の端面および外周面を有する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は第二回動ピン７２を介して中間部材２０に回動可能に連結される。なお、図示せぬＥリングが第二回動ピン７２の外周面の両端部に形成されたリング状の溝に嵌装されることにより、第二回動ピン７２は上部固定部材３０および中間部材２０から脱落しない。 The second rotation pin 72 is a member that forms a rotation shaft that rotatably connects the upper fixing member 30 to the intermediate member 20. The second rotation pin 72 is a generally cylindrical member having a pair of end surfaces and an outer peripheral surface, and is inserted through the front portions of the upper fixing member 30 and the intermediate member 20.

Both end portions of the outer peripheral surface of the pressure receiving pin 73 (portions close to the pair of end surfaces) extend along the circumferential direction of the pressure receiving pin 73. Thus, a ring-shaped groove is formed. By inserting the pressure receiving pin 73 into the upper fixing member 30, the pressure receiving pin 73 is pivotally supported by the upper fixing member 30. Note that the E-ring (not shown) is fitted into ring-shaped grooves formed at both ends of the outer peripheral surface of the pressure receiving pin 73, so that the pressure receiving pin 73 does not fall off the upper fixing member 30.

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.

以下では、図１０（ａ）から（ｃ）を用いてバネ６０の付勢力の調整について説明する。
図１０（ａ）に示す如く、カム部材１６０は前後方向に長さＤ１、曲板部１６３の高さＨ１で形成されている。この形状により、曲板部１６３の前後方向位置及び上下方向幅が決定する。つまり、曲板部１６３が第一スライダ４０のカム当接面４１に当接する箇所が定まるため、バネ６０の付勢力が決まる。 Hereinafter, the adjustment of the biasing force of the spring 60 will be described with reference to FIGS.
As shown in FIG. 10A, the cam member 160 is formed with a length D1 in the front-rear direction and a height H1 of the curved plate portion 163. With this shape, the longitudinal position and the vertical width of the curved plate portion 163 are determined. That is, since the location where the curved plate portion 163 contacts the cam contact surface 41 of the first slider 40 is determined, the urging force of the spring 60 is determined.

図１０（ｂ）及び（ｃ）に示す如く、カム部材１６０を別形状のカム部材１７０・１８０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。カム部材１７０は、前後方向の長さＤ２がカム部材１６０の長さＤ１と比較して短く形成されている。カム部材１８０は、曲板部１８３の高さＨ２がカム部材１６０の高さＨ１と比較して長く形成されている。 As shown in FIGS. 10B and 10C, the urging force of the spring 60 can be adjusted by replacing the cam member 160 with cam members 170 and 180 having different shapes. The cam member 170 is formed such that the length D2 in the front-rear direction is shorter than the length D1 of the cam member 160. The cam member 180 is formed such that the height H2 of the curved plate portion 183 is longer than the height H1 of the cam member 160.

カム部材１６０をカム部材１７０に付け替えた場合、曲板部１７３の前後方向位置は曲板部１６３よりも後方となる。このため、曲板部１７３は曲板部１６３よりも後方で第一スライダ４０のカム当接面４１に当接するため、第二ウイング部材を閉状態とした際のバネ６０の付勢力を弱くすることができる。 When the cam member 160 is replaced with the cam member 170, the position of the curved plate portion 173 in the front-rear direction is behind the curved plate portion 163. For this reason, since the curved plate part 173 contacts the cam contact surface 41 of the first slider 40 behind the curved plate part 163, the biasing force of the spring 60 when the second wing member is closed is weakened. be able to.

また、カム部材１６０をカム部材１８０に付け替えた場合、曲板部１８３の高さＨ２が曲板部１６３の高さＨ１よりも長くなる。これによって、曲板部１８３の上端面の上下位置が曲板部１６３の上端面の上下位置よりも高くなるため、第二ウイング部材を閉状態から開状態とする際のバネ６０の付勢力を強くすることができる。 When the cam member 160 is replaced with the cam member 180, the height H2 of the curved plate portion 183 becomes longer than the height H1 of the curved plate portion 163. As a result, the vertical position of the upper end surface of the curved plate portion 183 is higher than the vertical position of the upper end surface of the curved plate portion 163, so that the biasing force of the spring 60 when the second wing member is opened from the closed state is reduced. Can be strong.

上記の如く、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。 As described above, 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 another shape cam member. 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.

また、カム部材１６０は、金属製の板状部材１６を折り曲げて形成された単一の部材で構成されるため、部品点数を増加させることなく、コストを抑制してバネ６０の付勢力を調整可能とできる。
さらに、カム部材を別形状とすることで当接部（曲板部）の位置を任意に設定することができる。つまり、第一スライダ４０がカム部材に当接する位置を変更してバネ６０の付勢力を柔軟に調整することが可能となるのである。 In addition, since the cam member 160 is composed of a single member formed by bending the metal plate-like member 16, the cost is suppressed without increasing the number of parts, and the biasing force of the spring 60 is adjusted. Possible.
Furthermore, the position of the contact portion (curved plate portion) can be arbitrarily set by making the cam member another shape. That is, the biasing force of the spring 60 can be flexibly adjusted by changing the position where the first slider 40 abuts the cam member.

また、本実施形態に係るヒンジ１００において、カム部材１６０は、固定部の一端部である上側固定部１６１・１６１に第一係止部１６１ａ・１６１ａが形成される。そして、第一係止部１６１ａ・１６１ａが第一回動ピン７１に着脱可能に係止されている。また、固定部の他端部である下側固定部１６２・１６２に第二係止部第二係止部１６２ａ・１６２ａが形成される。そして、第二係止部１６２ａ・１６２ａが下部固定部材１１０の側板１１２・１１２から突出した係止部１１２ａに着脱可能に係止される。これにより、ボルト等の固定具を外すだけで下部固定部材１１０に対してカム部材１６０を容易に着脱することができる。つまり、カム部材１６０を別形状のカム部材に付け替えることを容易に行うことができる。 Further, in the hinge 100 according to the present embodiment, the cam member 160 has first locking portions 161a and 161a formed on the upper fixing portions 161 and 161 which are one end portions of the fixing portions. And the 1st latching | locking part 161a * 161a is latched by the 1st rotation pin 71 so that attachment or detachment is possible. Moreover, the 2nd latching | locking part 2nd latching | locking part 162a * 162a is formed in the lower side fixing | fixed part 162 * 162 which is the other end part of a fixing | fixed part. And the 2nd latching | locking part 162a * 162a is detachably latched by the latching | locking part 112a which protruded from the side plate 112 * 112 of the lower fixing member 110. As shown in FIG. Thereby, the cam member 160 can be easily attached to and detached from the lower fixing member 110 only by removing a fixing tool such as a bolt. That is, it is possible to easily replace the cam member 160 with another shape cam member.

In addition, the cam member 480 has a contact surface support portion 484 extending on the first slider 440 side (upper side) when the second wing member is in the open state in the upper fixing portion 481. Then, the contact surface support portion 484 is bent inward by 90 degrees to form the contact surface 485 that contacts the protrusion 442 when the second wing member is in the open state.

本実施形態においては上記の如く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φ°から９０°までの範囲で大きくなるとき（φ°＜θ≦９０°のとき）に、当接面４８５が突起部４４２を押し上げることにより、第一スライダ４４０に対してトルクを付与することができる。この際、図１２に示す如く、第一スライダ４４０は第一回動ピン７１の外周面から離間しているため、第一スライダ４４０は第一回動ピン７１に力を加えないため、ヒンジ４００の使用者がヒンジ４００のメンテナンスをしやすくすることができる。 In the present embodiment, by configuring as described above, when the rotation angle θ of the original cover 3 with respect to the main body 2 of the multifunction machine 1 increases in the range from φ ° to 90 ° (φ ° <θ ≦ 90 ° When the contact surface 485 pushes up the protrusion 442, torque can be applied to the first slider 440. At this time, as shown in FIG. 12, since the first slider 440 is separated from the outer peripheral surface of the first rotation pin 71, the first slider 440 does not apply force to the first rotation pin 71. The user can easily maintain the hinge 400.

また、本実施形態においては図１２に示す如く、カム部材４８０の上側固定部４８１には、内周部が略半円状に形成された第一係止部４８１ａが形成されている。第一係止部４８１ａの内周形状は第一回動ピン７１の周囲に嵌装された軸受け７４の外周形状と略同径に形成されている。本実施形態において、軸受け７４上側固定部４８１が位置する左右方向位置まで拡幅されている。そして、第一係止部４８１ａを軸受け７４に係止することにより、上側固定部４８１が側板１１２に係止される。これにより、カム部材４８０の第一係止部４８１ａが第一回動ピン７１に直接的に当接しない構成としている。 In this embodiment, as shown in FIG. 12, the upper fixing portion 481 of the cam member 480 is formed with a first locking portion 481a having an inner peripheral portion formed in a substantially semicircular shape. The inner peripheral shape of the first locking portion 481 a is formed to have substantially the same diameter as the outer peripheral shape of the bearing 74 fitted around the first rotation pin 71. In the present embodiment, the width of the bearing 74 is fixed to the horizontal position where the upper fixing portion 481 is located. Then, the upper fixing portion 481 is locked to the side plate 112 by locking the first locking portion 481 a to the bearing 74. Thus, the first locking portion 481a of the cam member 480 is configured not to directly contact the first rotation pin 71.

以下では、図１３（ａ）及び（ｂ）を用いて本発明に係るヒンジの第五実施形態であるヒンジにおける下部固定部材５１０を本体２に対して固定する手法について説明する。 Hereinafter, a method of fixing the lower fixing member 510 in the hinge, which is the fifth embodiment of the hinge according to the present invention, to the main body 2 will be described with reference to FIGS.

図１３（ａ）及び（ｂ）に示す如く、本実施形態において下部固定部材５１０は、板状の固定具である固定板５２１を介して本体２に固定される。そして、下部固定部材５１０において、底板５１１の後端部かつ左右中央部となる部分には貫通孔５１１ａが形成される。また、背板５１３の下部かつ左右略中央部となる部分には、固定孔５１３ａが形成される。固定板５２１には、下部固定部材５１０の側（上側）に立設されるとともに、固定孔５２２ａが開口された固定部５２２が形成されている。固定孔５２２ａの内周面には雌ねじ部が形成されている。 As shown in FIGS. 13A and 13B, in the present embodiment, the lower fixing member 510 is fixed to the main body 2 via a fixing plate 521 which is a plate-like fixing tool. In the lower fixing member 510, a through hole 511 a is formed in a portion that becomes the rear end portion and the left and right center portion of the bottom plate 511. In addition, a fixing hole 513a is formed in a lower portion of the back plate 513 and a portion that is substantially in the center on the left and right. The fixing plate 521 is provided with a fixing portion 522 that is erected on the lower fixing member 510 side (upper side) and in which a fixing hole 522a is opened. An internal thread portion is formed on the inner peripheral surface of the fixing hole 522a.

また、図１３（ａ）及び（ｂ）に示す如く下部固定部材５１０における本体２の面（底板５１１）には、長孔５１１ｂが開口される。さらに、固定板５２１には、下部固定部材５１０の側（上側）に立設されるとともに挿通孔５２３ａが開口された固定部５２３が形成されている。 Further, as shown in FIGS. 13A and 13B, a long hole 511 b is opened on the surface (bottom plate 511) of the main body 2 in the lower fixing member 510. Further, the fixing plate 521 is formed with a fixing portion 523 that is erected on the lower fixing member 510 side (upper side) and in which the insertion hole 523a is opened.

このような構成において、固定板５２１が本体２に固定され、固定部５２２が貫通孔５１１ａに挿通されると同時に固定部５２２が長孔５１１ｂに挿通された状態で、固定孔５１３ａに固定ボルト５４１が挿入され、固定孔５２２ａに固定ボルト５４１が螺入され、挿通孔５２３ｂに樹脂製のピン５４２が挿通されることにより、下部固定部材５１０が本体２に固定されるのである。本実施形態においては、固定孔５２２ａに対する固定ボルト５４１の螺入長さを調節することにより、固定板５２１及び本体２に対する下部固定部材５１０の前後位置を調節可能としている。 In such a configuration, the fixing plate 521 is fixed to the main body 2, the fixing portion 522 is inserted into the through hole 511a, and at the same time the fixing portion 522 is inserted into the long hole 511b, the fixing bolt 541 is inserted into the fixing hole 513a. Is inserted, the fixing bolt 541 is screwed into the fixing hole 522a, and the resin pin 542 is inserted into the insertion hole 523b, whereby the lower fixing member 510 is fixed to the main body 2. In this embodiment, the front-rear position of the lower fixing member 510 relative to the fixing plate 521 and the main body 2 can be adjusted by adjusting the screwing length of the fixing bolt 541 into the fixing hole 522a.

本実施形態においては上記の如く構成することにより、下部固定部材５１０を固定板５２１に対して圧入ピンを用いて固定する構成と比較して、作業者が手作業でピン５４２を用いて下部固定部材５１０を固定板５２１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、樹脂製のピン５４２を用いているため、ヒンジを軽量化することができる。また、挿通孔５２３ｂに対してピン５４２を水平方向に挿入する構成であるため、輸送時等の振動によってピン５４２が脱落することを防止できる。 In this embodiment, the lower fixing member 510 is manually fixed to the fixing plate 521 by using the pin 542 as compared with the configuration in which the lower fixing member 510 is fixed to the fixing plate 521 by using the press-fit pin. Since the member 510 can be fixed to the fixing plate 521, the working efficiency is improved. Further, since the resin pin 542 is used instead of the metal press-fit pin, the hinge can be reduced in weight. In addition, since the pin 542 is inserted in the horizontal direction with respect to the insertion hole 523b, it is possible to prevent the pin 542 from dropping off due to vibration during transportation.
