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 the second connected object to the first connected object so as to be openable and closable, and an electronic device provided with 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 used in offices such as copiers, facsimiles, and scanners are provided with a document reading unit (contact glass) on the upper surface of the main body and a document crimping plate covering the document reading unit. .. The document crimping plate is for bringing the document placed on the document reading section into close contact with the document reading section and holding the position of the document with respect to the document reading section.

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。 As an instrument for connecting the main body of the office equipment and the document crimping plate, the first wing member, the cam member fixed to the first wing member, and the first wing member are rotatably connected via a rotation shaft. A second wing member to be moved, a slide member that can move in a direction approaching the cam member and a direction away from the cam member, and a slide member being used as a cam member by urging the slide member in a direction approaching the cam member. A hinge comprising an urging member to be brought into contact is known.

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）。 Further, the hinge is provided with an intermediate member and a fixing member as the second wing member, and the original crimping plate is lifted to the main body of the multifunction device with the fixing member open to the intermediate member (lift state). In some cases, a relatively thick original can be placed between the main body (contact glass) and the original crimping plate, and maintenance and inspection can be easily performed.
Further, in an office machine provided with such a hinge, in a state where the intermediate member and the fixing member are open (lift state), between the rear of the hinge and the intermediate member and the fixing member, for example, a tool, clothes, fingers, etc. Some of them are provided with a foreign matter pinching prevention portion for preventing foreign matter from entering and being pinched (see Patent Document 1).

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 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) (FIG. 9). 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 (see FIG. 8). The open state refers to a state in which the document crimping plate 3 is open with respect 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 an embodiment of the urging member, and is composed of a metal wound spring (compression spring). The spring 60 is housed inside the intermediate member 20 (a spring receiving hole between 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 abuts on 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 abuts on 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 first slider 40 is 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 direction of compression tries 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 shaft 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 rotation shaft 71. The damper 62 generates a reaction force when the tip portion receives a pressing force 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 member having a substantially cylindrical shape (pin shape). The cam member 75 is arranged in the front lower part of the first rotation shaft 71 and is attached to the lower fixing member 10. The cam member 75 abuts on the cam contact portion 42 (rear surface of the cam contact portion 42) of the first slider 40. When the second wing member is closed, the cam contact portion 42 of the first slider 40 comes into contact with the cam member 75, and the cam contact portion 52 of the second slider 50 comes into contact with the pressure receiving portion 73. Further, when the rotation angle θ> 60 degrees of the second wing member, the cam contact portion 42 of the first slider 40 is in a state of being 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。 As a result of the cam contact portion 42 of the first slider 40 contacting the cam member 75 and the cam contact portion 52 of the second slider 50 contacting the pressure receiving portion 73, the elastic force generated in the spring 60 causes the intermediate member 20 to abut. The (second wing member) is urged to rotate in the opening direction with respect to the lower fixing member 10, and the upper fixing member 30 is urged to rotate in the closing direction with respect 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 toward 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 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 direction in which the second wing member is opened 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 the present embodiment, the rotational force for closing the hinge 100 due to the own weight of the document 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 portion 42 or the cam member 75 of the first slider 40 is predetermined so that the rotational force to be applied is substantially in equilibrium.
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.
