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事務機器の原稿圧着板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 connection object to the first connection object so as to be openable and closable, a manuscript crimping plate of office equipment provided with the hinge, 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 provided with an urging member to be brought into contact is known.

また、ヒンジを備える事務機器においては、第一ウイング部材と第一ウイング部材との後方から、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)。
さらに、ヒンジには、第二ウイング部材が、原稿圧着板に固定される固定部材と、第一ウイング部材と固定部材とを連結する中間部材とを備えるものがある。前記ヒンジでは、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。このようなヒンジにおいても、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おそれがあることから、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構成を備えることが考えられる。
In addition, some office equipment equipped with a hinge is provided with a foreign matter pinching prevention portion for preventing foreign matter such as tools, clothes, and fingers from entering and being pinched from behind the first wing member and the first wing member. (See Patent Document 1).
Further, some hinges include a second wing member having a fixing member fixed to the original crimping plate and an intermediate member connecting the first wing member and the fixing member. In the hinge, the fixing member is open with respect to the intermediate member (lift state), the original crimping plate is lifted with respect to the main body of the multifunction device, and the space between the main body (contact glass) and the original crimping plate is set. Place relatively thick documents in the room, and make it easier to perform maintenance and inspections. Even in such a hinge, when the intermediate member and the fixing member are open (lifted state), foreign matter such as a tool, clothes, or fingers may get caught between the intermediate member and the fixing member from the rear of the hinge. Therefore, it is conceivable to provide a configuration for preventing foreign substances such as tools, clothes, and fingers from entering and being pinched.

When the cam member 75 is attached to the lower fixing member 10 and 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 of the second slider 50. The contact portion 52 comes into contact with the pressure receiving portion 73. As a result, the elastic force generated in the spring member 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 rotate in the opening direction. It is urged to rotate in the closing direction. 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.
Further, even when the second wing member is opened, the cam contact portion 42 of the first slider 40 abuts on the cam member 75, and the cam contact portion 52 of the second slider 50 hits the pressure receiving portion 73. Contact. As a result, the elastic force generated in the spring member 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 rotate in the opening direction. It is urged to rotate in the closing direction.
Further, even when the second wing member is fully opened, the cam contact portion 42 of the first slider 40 abuts on the cam member 75, and the cam contact portion 52 of the second slider 50 hits the pressure receiving portion 73. Contact. As a result, the elastic force generated in the spring member 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 rotate in the opening direction. It is urged to rotate in the closing direction.
That is, as shown in FIGS. 4 to 6, the cam contact portion 42 of the first slider 40 is a cam from the closed state to the fully open state of the second wing member regardless of the rotation angle θ of the second wing member. It is configured to abut on the member 75. From the closed state to the fully open state of the second wing member (the closed state, the open state, and the fully open state of the second wing member), the cam contact portion 42 of the first slider 40 comes into contact with the cam member 75, and the second slider The cam contact portion 52 of 50 comes into contact with the pressure receiving portion 73. The elastic force generated in the spring member 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 closes with respect to the intermediate member 20. It is urged to rotate in the direction.

以上のように、第二ウイング部材の閉状態から全開状態まで、第一スライダ40のカム当接部42がカム部材75に当接するように構成されて、バネ部材60により第二ウイング部材の閉状態から全開状態まで第二ウイング部材が第一ウイング部材に対して開く方向に回動するように付勢されることから、バネ部材60の困難な付勢力の調整を要さないものとすることができ、また、バネ部材60によって第二ウイング部材が第一ウイング部材に対して開く方向に回動するように付勢するものを簡易な構成とすることができる。 As described above, the cam contact portion 42 of the first slider 40 is configured to abut on the cam member 75 from the closed state to the fully open state of the second wing member, and the second wing member is closed by the spring member 60. Since the second wing member is urged to rotate in the opening direction with respect to the first wing member from the state to the fully open state, it is not necessary to adjust the urging force of the spring member 60, which is difficult. In addition, a spring member 60 can be used to urge the second wing member to rotate in the opening direction with respect to the first wing member.

When adjusting the state in which the rotational force for closing the second wing member and the rotational force for opening the second wing member due to the urging force of the spring member 60 are maintained in a substantially equilibrium state. In order to remove the urging member 85 from the partition member 80, the urging member 85 is bent from the inclination angle of the contact portion 86 of the urging member 85 and the lower end of the portion inclined forward and downward, and extends so as to be inclined backward and downward. This can be done by changing the inclination angle of the protruding portion, replacing the urging member 85 with one having a desired urging force, or the like.
Therefore, the rotational force for closing the second wing member due to the weight of the original crimping plate 3 (second connecting object) fixed to the upper fixing member 30 (second wing member) and the spring member 60. The work of adjusting the state in which the rotational force for opening the second wing member due to the urging force of the second wing member and the state in which the second wing member is substantially in equilibrium is maintained can be easily performed.

また、付勢部材85を仕切部材80に取付けている固定具89であるビスの頭部(固定具89の操作部89a)は、仕切部材80の仕切部82の下方に位置し、少なくとも第二ウイング部材の全開状態においては下方に露出した状態とされている。このため、第二ウイング部材を全開状態にして、ヒンジ100の他の部材を取外すことを要さずに、付勢部材85の仕切部材80に対する着脱させる作業を容易に行うことができる。したがって、上部固定部材30(第二ウイング部材)に固定された原稿圧着板3(第二連結対象物)の自重に起因して第二ウイング部材を閉じようとする回転力と、バネ部材60の付勢力に起因して第二ウイング部材を開こうとする回転力と、が概ね平衡した状態とを保持した状態の調整する作業を、より容易に行うことができる。 Further, the head of the screw (operation portion 89a of the fixture 89), which is the fixture 89 that attaches the urging member 85 to the partition member 80, is located below the partition portion 82 of the partition member 80, and is at least second. When the wing member is fully open, it is exposed downward. Therefore, the work of attaching and detaching the urging member 85 to the partition member 80 can be easily performed without having to leave the second wing member in the fully open state and remove the other members of the hinge 100. Therefore, the rotational force for closing the second wing member due to the weight of the original crimping plate 3 (second connecting object) fixed to the upper fixing member 30 (second wing member) and the spring member 60. It is possible to more easily perform the work of adjusting the state in which the rotational force for opening the second wing member due to the urging force and the state in which the second wing member is substantially in equilibrium are maintained.

In a state where the rear surface of the positioning portion 83 of the member 80 is in contact with the rear surface, the through hole of the urging member 85 and the through hole of the partition member 80 are in the same state.
When attaching the urging member 85 to the partition member 80, it is easy to bring the front surface of the convex portion 87 of the urging member 85 and the rear surface of the positioning portion 83 of the partition member 80 into contact with each other. The through hole of the urging member 85 and the through hole of the partition member 80 can be in the same state.
Therefore, the work of attaching the urging member 85 to the partition member 80 can be performed relatively easily.

第一スライダ40は、窪み部43を備える。第一スライダ40のカム当接部43の一部が凹状に形成される。前記第一スライダ40のカム当接部43の一部が凹状に形成される部分は、窪み部43として構成される。第一スライダ40の窪み部43は、カム当接部43の上面の前後中途部に形成される。第一スライダ40の窪み部43は、第一スライダ40の左端から右端に亘って筋状に構成される。
ここで、付勢部材85における、上端から前下に傾斜する部分(当接部86)と、当該前下に傾斜する部分の下端から折り曲げられて後下に傾斜するように延出する部分と、が連接されて構成されることから、当該部分が側面視略V字状に構成される。付勢部材85における、上端から前下に傾斜する部分(当接部86)と、当該前下に傾斜する部分の下端から折り曲げられて後下に傾斜するように延出する部分との境界部分は、その前方(第一スライダ40側)が山状に構成されて、前方に突出するように構成され、突出部88として構成される。
第一スライダ40の窪み部43は、付勢部材85の突出部88の前面の形状と概ね一致するように構成される。
The first slider 40 includes a recess 43. A part of the cam contact portion 43 of the first slider 40 is formed in a concave shape. A portion of the first slider 40 in which a part of the cam contact portion 43 is formed in a concave shape is configured as a recessed portion 43. The recessed portion 43 of the first slider 40 is formed in the middle of the front and rear of the upper surface of the cam contact portion 43. The recessed portion 43 of the first slider 40 is formed in a streak shape from the left end to the right end of the first slider 40.

The recessed portion 43 of the first slider 40 is configured to substantially match the shape of the front surface of the protruding portion 88 of the urging member 85.

第二ウイング部材の第一ウイング部材に対する回動角度θが所定の角度にあるとき、即ち、複合機1の本体2に対する原稿圧着板3の回動角度θが前記所定の角度にあるとき、第一スライダ40の窪み部43に付勢部材85の突出部88が当接して入り込んだ状態となり、第二ウイング部材の第一ウイング部材に対する回動姿勢が保持された状態となる。第一スライダ40の窪み部43に付勢部材85の突出部88が入り込む際に、また、第一スライダ40の窪み部43に付勢部材85の突出部88が脱落する際に、クリック感が生じる。
例えば、第一スライダ40の窪み部43に付勢部材85の突出部88が当接して入り込んだ状態となるときの第二ウイング部材の第一ウイング部材に対する回動角度は、回動角度θ=90°(全開状態)に設定されてる。なお、第一スライダ40の窪み部43に付勢部材85の突出部88が当接して入り込んだ状態となるときの第二ウイング部材の第一ウイング部材に対する回動角度は、90°以外の他の角度に設定することも可能である。
When the rotation angle θ of the second wing member with respect to the first wing member is at a predetermined angle, that is, when the rotation angle θ of the document crimping plate 3 with respect to the main body 2 of the multifunction device 1 is at the predetermined angle. The protruding portion 88 of the urging member 85 comes into contact with the recessed portion 43 of the slider 40 and enters the recessed portion 43, and the rotational posture of the second wing member with respect to the first wing member is maintained. When the protruding portion 88 of the urging member 85 enters the recessed portion 43 of the first slider 40, and when the protruding portion 88 of the urging member 85 falls off into the recessed portion 43 of the first slider 40, a click feeling is felt. Occurs.
For example, the rotation angle of the second wing member with respect to the first wing member when the protruding portion 88 of the urging member 85 comes into contact with the recessed portion 43 of the first slider 40 is the rotation angle θ =. It is set to 90 ° (fully open). The rotation angle of the second wing member with respect to the first wing member when the protruding portion 88 of the urging member 85 abuts on the recessed portion 43 of the first slider 40 and enters the recessed portion 43 is other than 90 °. It is also possible to set the angle of.

以上のように、第二ウイング部材の第一ウイング部材に対する回動角度θが所定の角度にあるとき、第一スライダ40の窪み部43に付勢部材85の突出部88が当接して入り込んだ状態となり、第二ウイング部材の第一ウイング部材に対する回動姿勢が保持された状態となる。
このため、第二ウイング部材の第一ウイング部材に対する回動角度θが所定の角度にあるとき、簡易な構成で、バネ部材60および付勢部材85の付勢力にかかわらず第二ウイング部材の第一ウイング部材に対する回動姿勢が保持された状態とすることができる。
なお、第一スライダ40が窪み部43に代えて付勢部材85側に突出する突出部を備え、且つ、付勢部材85が突出部88に代えて前記第一スライダ40の突出部の外面の形状と概ね一致する窪み部を備えて、第二ウイング部材の第一ウイング部材に対する回動角度θが所定の角度にあるとき、第一スライダ40の突出部が付勢部材85の窪み部に当接して入り込んだ状態となり、第二ウイング部材の第一ウイング部材に対する回動姿勢が保持された状態となる構成とすることもできる。
As described above, when the rotation angle θ of the second wing member with respect to the first wing member is at a predetermined angle, the protruding portion 88 of the urging member 85 abuts and enters the recessed portion 43 of the first slider 40. The state is set, and the rotational posture of the second wing member with respect to the first wing member is maintained.
Therefore, when the rotation angle θ of the second wing member with respect to the first wing member is at a predetermined angle, the second wing member has a simple structure regardless of the urging force of the spring member 60 and the urging member 85. It is possible to keep the rotational posture with respect to the wing member.
The first slider 40 is provided with a protruding portion that protrudes toward the urging member 85 instead of the recess 43, and the urging member 85 replaces the protruding portion 88 on the outer surface of the protruding portion of the first slider 40. With a recess that roughly matches the shape, the protrusion of the first slider 40 hits the recess of the urging member 85 when the rotation angle θ of the second wing member with respect to the first wing member is at a predetermined angle. It is also possible to have a configuration in which the second wing member is in contact with the first wing member and the rotational posture of the second wing member with respect to the first wing member is maintained.

図7から図13に示すように、フェンス部材76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76は、中間部材20の閉状態から全開状態まで(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76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76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76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。
As shown in FIGS. 7 to 13, the fence member 76 is located below the cam contact portion 42 of the cam member 75 and the first slider 40 (in the open state of the second wing member, the cam member 75) in the vicinity of the cam member 75. And in front of the contact portion of the first slider 40). The fence member 76 is in contact with the cam of the first slider 40 from the outside of the first slider 40 and the cam member 75 from the closed state to the fully open state of the intermediate member 20 (over the entire rotation range of the intermediate member 20). Prevents foreign matter (for example, a document) from entering the contact portion side between the portion 42 and the cam member 75. The fence member 76 shields the space from the outside by hiding the cam member 75 (the contact portion between the cam contact portion 42 of the first slider 40 and the cam member 75) from the lower outside or the front outside. It is configured as follows.
The fence member 76 is supported (rotatably) so as to hang from the first slider 40 (cam contact portion 42). The fence member 76 is configured to be movable along with the rotation operation of the intermediate member 20 or the movement operation of the first slider 40.

また、フェンス部材76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 76 is supported so as to hang from the first slider 40, and is below the cam member 75 and the cam contact portion 42 of the first slider 40 (opening of the second wing member) in the vicinity of the cam member 75. In the state, it is arranged in front of the contact portion between the cam member 75 and the first slider 40), and the cam contact portion 42 of the first slider 40 and the cam member 75 are contacted from the outside of the first slider 40 and the cam member 75. In order to prevent foreign matter (for example, a document) from entering the contact portion side, 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 cam contact of the first slider 40. It is possible to reliably prevent oil from adhering to the original by entering the contact portion side between the contact portion 42 and the cam member 75.
Further, since the fence member 76 is configured to shield the space from the outside of the contact portion between the cam contact portion 42 of the first slider 40 and the cam member 75 from the outside, the fence member 76 is made of a resin material. The hinge 100 can be configured to have a relatively high flame retardancy by reducing the exposed portion of the member (first slider 40 or the like) composed of the above.

ヒンジ100は、カバー部材77を備える。

The cover member 77 is configured so that the inside of the second wing member is not exposed (not visible from the outside). The cover member 77 covers the front opening and the lower opening (bottom side of the second wing member) of the intermediate member 20 so that the first slider 40, the second slider 50, the spring member 60, the damper 62, and the like are not exposed. It is configured as follows. The front plate of the cover member 77 is arranged in front of the first slider 40, and the pair of side plates of the cover member 77 are arranged on the left and right outer sides of the side plates 21 and 21 of the intermediate member 20. The lower plate of the cover member 77 is arranged below the opening below the intermediate member 20, below the contact portion between the cam contact portion 42 of the first slider 40 and the cam member 75, and below the fence member 76. To.

このように、カバー部材77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。 As described above, since the cover member 77 is provided and covers the opening below the intermediate member 20 so that the inside of the second wing member is not exposed, the member made of the resin material or the like inside the hinge 100 (first). By reducing the exposed portion of the slider 40 and the like), the hinge 100 can be configured to have a relatively high flame retardancy.

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。 Further, the shielding member 91 of the foreign matter pinching prevention portion 90 can be made of a material having a relatively high flame retardancy. With such a configuration, the hinge 100 can be configured to have a relatively high flame retardancy.
