Description

本発明は、複写機、印刷機、ファクシミリ、スキャナー等の原稿圧着板を有する事務機器に用いて好適な、原稿圧着板開閉装置、及びその原稿圧着板を備えた事務機器に関するものである。   The present invention relates to a document crimping plate opening / closing device suitable for office machines having a document crimping plate such as a copying machine, a printing machine, a facsimile machine, and a scanner, and to an office device equipped with the document crimping plate.

複写機、印刷機、ファクシミリ、スキャナー等の事務機器の機器本体には、その機器本体の上面後部に機器本体に備えたコンタクトガラスの上面を覆う原稿圧着板が原稿圧着板開閉装置を介して開閉可能に取り付けられている。原稿圧着板開閉装置は、一種のヒンジ機構であり、原稿圧着板をヒンジ軸まわりに回動可能に軸支して、機器本体の上面のコンタクトガラス上に原稿圧着板を圧着させることができると共に、そのコンタクトガラスを露出させることができる。原稿をコンタクトガラス上にセットするには、原稿圧着板を開いてコンタクトガラスの上面を露出させ、そのコンタクトガラス上に原稿を載置した後、原稿圧着板を閉じて、原稿圧着板で原稿をコンタクトガラス上に圧着させるものである。   In the main body of office equipment such as copiers, printing machines, facsimile machines, scanners, etc., the original pressure plate that covers the upper surface of the contact glass provided on the main body of the device is opened and closed via the original pressure plate opening / closing device. It is attached as possible. The document crimping plate opening / closing device is a kind of hinge mechanism. The document crimping plate is pivotally supported around a hinge axis so that the document crimping plate can be crimped onto the contact glass on the upper surface of the apparatus body. The contact glass can be exposed. To set the document on the contact glass, open the document crimping plate to expose the top surface of the contact glass, place the document on the contact glass, close the document crimping plate, and then place the document on the document crimping plate. It is to be crimped onto contact glass.

このような原稿圧着板開閉装置の中には、コンプレッションスプリングの弾力により本来の重量を感じさせることなく原稿圧着板を開くことができる原稿圧着板開閉装置が知られている（例えば、特許文献１、２参照。）。この原稿圧着板開閉装置は、事務機器の機器本体に取り付けられる取付部材と、この取付部材にヒンジピンを介して回動可能に設けられていると共に原稿圧着板を支持する支持部材と、支持部材と取付部材との間に設けられる一対のスプリング受け部材を兼ねる一対のスプリングケースと、この一対のスプリングケース間に弾設され支持部材を開成方向へ付勢するコンプレッションスプリングとを備えている。このコンプレッションスプリングによって支持部材を介して原稿圧着板が開成方向に回転付勢されているので、原稿圧着板を開成方向に回転するときには、コンプレッションスプリングの弾力により本来の重量を感じさせることなく原稿圧着板を開くことができる。
特開２００４−１０１６２０号 実公平５−８５９９号 Among such document crimping plate opening / closing devices, there is known a document crimping plate opening / closing device capable of opening the document crimping plate without feeling the original weight due to the elasticity of the compression spring (for example, Patent Document 1). 2). The document crimping plate opening and closing device includes an attachment member that is attached to an apparatus main body of an office machine, a support member that is rotatably provided on the attachment member via a hinge pin, and that supports the document crimping plate, a support member, A pair of spring cases also serving as a pair of spring receiving members provided between the mounting member and a compression spring that is elastically provided between the pair of spring cases and biases the support member in the opening direction. Since the original pressure plate is urged to rotate in the opening direction by the compression spring through the support member, when the original pressure plate is rotated in the opening direction, the original pressure is not felt by the elasticity of the compression spring. You can open the board.

特許文献１、２に記載されている原稿圧着板開閉装置は、コンプレッションスプリングの弾力を変化させて支持部材の回転トルクを調節するトルク調節手段が設けられている。特許文献１に記載されている原稿圧着板開閉装置では、コンプレッションスプリング内に収装され、一対のスプリングケースのどちらか一方に回転可能に支持されるダンパーを備え、このダンパーの外周のネジ部に、ダンパーの軸方向には移動するが、ダンパーの軸回りには回転できないアジャストプレートが螺合されている。このアジャストプレートにはコンプレッションスプリングの一端部が当接されてダンパーを回転させることによって、アジャストプレートがダンパーに対して軸方向に回転移動して、コンプレッションスプリングの弾力が変化するようになっている。しかし、ダンパーはスプリングケース内のコンプレッションスプリング内に設けられているために、ダンパーの回転を行い難いので、トルクの調節を簡単に行えず、操作性が悪いという問題があった。   The document crimping plate opening / closing device described in Patent Documents 1 and 2 is provided with torque adjusting means for adjusting the rotational torque of the support member by changing the elasticity of the compression spring. The document crimping plate opening / closing device described in Patent Document 1 includes a damper that is housed in a compression spring and is rotatably supported by one of a pair of spring cases. An adjustment plate that moves in the axial direction of the damper but cannot rotate around the axis of the damper is screwed together. One end portion of the compression spring is brought into contact with the adjustment plate and the damper is rotated, whereby the adjustment plate is rotated in the axial direction with respect to the damper, so that the elasticity of the compression spring is changed. However, since the damper is provided in the compression spring in the spring case, it is difficult to rotate the damper. Therefore, there is a problem that the torque cannot be easily adjusted and the operability is poor.

また、特許文献２に記載されている原稿圧着板開閉装置では、一方のスプリングケースに螺合されている調節ネジで軸方向へ移動可能にスプリング受座を設け、調節ネジを回転させることによってスプリングケース内のスプリング受座が移動し、コンプレッションスプリングの弾力が変化するようになっている。調節ネジはスプリングケースから突出しているので、調節ネジを回転させてスプリング受座の位置を調節し易いが、しかし、調節ネジを回転させる際に、スプリング受座がスプリングケース内で回転し得る状態で設けられているために、調節ネジの回転によってスプリング受座が回転して、この回転に伴ってコンプレッションスプリングの端部が移動してコンプレッションスプリングが捩じれることがあり、その結果、コンプレッションスプリングの弾力を所望の弾力に調節することができない、すなわち、トルクの調節を正確に行えないことがある。   Further, in the document crimping plate opening / closing device described in Patent Document 2, a spring seat is provided so as to be movable in the axial direction with an adjusting screw screwed into one spring case, and the spring is formed by rotating the adjusting screw. The spring seat in the case moves and the elasticity of the compression spring changes. Since the adjustment screw protrudes from the spring case, it is easy to adjust the position of the spring seat by rotating the adjustment screw. However, when the adjustment screw is rotated, the spring seat can rotate in the spring case. Therefore, the spring seat is rotated by the rotation of the adjusting screw, and the end of the compression spring is moved by this rotation, and the compression spring may be twisted, and as a result, the compression spring In some cases, the elasticity cannot be adjusted to a desired elasticity, that is, the torque cannot be adjusted accurately.

本発明の目的は、トルクの調節を簡単にしかも正確に行える原稿圧着板開閉装置及び原稿圧着板を備えた事務機器を提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide a manuscript pressure plate opening / closing device that can easily and accurately adjust a torque, and an office machine equipped with a manuscript pressure plate.

The rear plate 23 includes a substantially rectangular rear plate 23 extending from one end (rear end) of the bottom plate 21 in an upward direction (including a substantially orthogonal direction) perpendicular to the bottom plate 21.

底板２１は、略矩形状に形成され、ネジやビス等で機器本体１１に取り付けられる。側板２２には、第１ヒンジピン１５が回り止め付きの軸受け（図示せず）を介して挿通されるシャフト孔（図示せず）が設けられている。側板２２のシャフト孔より前方で、かつ、内側（前方）に偏した位置には、受圧ローラ１７が挿通される受圧孔（図示せず）が設けられている。受圧ローラ１７は、第２スライダー７が当接する受圧部材であり、この受圧部材は、受圧ローラに限定されず、受圧ピンなどのピンやその他の部材であってもよい。   The bottom plate 21 is formed in a substantially rectangular shape, and is attached to the device main body 11 with screws, screws or the like. The side plate 22 is provided with a shaft hole (not shown) through which the first hinge pin 15 is inserted through a bearing (not shown) with a detent. A pressure receiving hole (not shown) through which the pressure receiving roller 17 is inserted is provided at a position forward of the shaft hole of the side plate 22 and deviated inward (forward). The pressure receiving roller 17 is a pressure receiving member with which the second slider 7 abuts. The pressure receiving member is not limited to the pressure receiving roller, and may be a pin such as a pressure receiving pin or other members.

支持部材３は、例えば、天板である上板３１と、上板３１の両側端部からそれぞれ上板３１に対して直交する下方向（略直交する方向も含む。）に延びる両側板３２と、側板３２の先端部を互いに対向する側に略９０°折り曲げてなる拘持板３３とからなる。これらの上板３１、両側板３２、拘持板３３で一対の第１スライダー６及び第２スライダー７をスライド可能に収容する収容部３４が構成されている。   The support member 3 includes, for example, an upper plate 31 that is a top plate, and both side plates 32 that extend from both side end portions of the upper plate 31 in a lower direction (including a substantially orthogonal direction) perpendicular to the upper plate 31. The holding plate 33 is formed by bending the front end portion of the side plate 32 approximately 90 ° to the sides facing each other. The upper plate 31, the side plates 32, and the holding plate 33 constitute a housing portion 34 that slidably houses the pair of first slider 6 and second slider 7.

両側板３２の一端部（後端部）には、シャフト挿通孔（図示せず）が設けられている。これらシャフト挿通孔と取付部材２の両側板２２のシャフト孔とが孔合わせされると共にこれら孔の間すなわち支持部材３の側板３２と取付部材２の側板２２との間に例えばワッシャー（図示せず）が設けられて、これら孔及びワッシャーに第１ヒンジピン１５が挿通されることによって、支持部材３が取付部材２に対して第１ヒンジピン１５を軸に回動可能に連結されている。   A shaft insertion hole (not shown) is provided at one end (rear end) of each side plate 32. These shaft insertion holes and the shaft holes of both side plates 22 of the attachment member 2 are aligned, and for example, a washer (not shown) is provided between these holes, that is, between the side plate 32 of the support member 3 and the side plate 22 of the attachment member 2. ) And the first hinge pin 15 is inserted into the holes and the washer, so that the support member 3 is connected to the mounting member 2 so as to be rotatable about the first hinge pin 15.

また、両側板３２の他端部（前端部（自由端部））には、第２ヒンジピン１６が挿通される第２ヒンジピン孔３６が設けられていると共に、後述する作動ピン１８が入り込む切欠部３７が設けられている。また、両側板３２には、例えば、支持部材３に対するリフト部材４の回動を行うための摺接部（図示せず）を設けてもよい。摺接部は、例えば、両側板３２の第２ヒンジピン孔３６と切欠部３７との間に略円状に２つ形成されている。これらの摺接部は、リフト部材４の側板４２の内面に接して支持部材３の側板３２の外面とリフト部材４の側板４２の内面との間にクリアランスを設けることにより、支持部材３に対するリフト部材４の回動が良好に行われるようにするためのものである。   Further, a second hinge pin hole 36 through which the second hinge pin 16 is inserted is provided at the other end portion (front end portion (free end portion)) of the both side plates 32, and a notch portion into which an operation pin 18 described later enters. 37 is provided. Moreover, you may provide the sliding contact part (not shown) for rotating the lift member 4 with respect to the supporting member 3 in the both-sides board 32, for example. For example, two sliding contact portions are formed in a substantially circular shape between the second hinge pin hole 36 and the notch portion 37 of the both side plates 32. These sliding contact portions are in contact with the inner surface of the side plate 42 of the lift member 4 and provide a clearance between the outer surface of the side plate 32 of the support member 3 and the inner surface of the side plate 42 of the lift member 4. This is to ensure that the member 4 is rotated well.

リフト部材４は、厚さが厚い原稿も機器本体１１の上面に安定して圧着させるためのものである。リフト部材４は、原稿圧着板１２の後端側にネジやビス等で取り付けられる矩形平板状の上板４１と、この上板４１の両端部からそれぞれ上板４１に対して直交する下方向（略直交する方向も含む。）に延びる両側板４２とから略コ字状であって支持部材３を覆うように形成されている。   The lift member 4 is used to stably press a thick original on the upper surface of the apparatus main body 11. The lift member 4 includes a rectangular flat plate upper plate 41 attached to the rear end side of the original cover 12 with screws, screws, and the like, and a downward direction perpendicular to the upper plate 41 from both ends of the upper plate 41 ( It is formed in a substantially U shape from both side plates 42 extending in a direction substantially orthogonal to the support member 3.

リフト部材４の一端部（前端部（取付部材２とは反対側の端部））の中央より上板４１側の箇所には第２ヒンジピン挿通孔（図示せず）が設けられていると共に、第２ヒンジピン挿通孔より他端部側で、かつ、中央より上板４１側とは反対側の箇所には作動部材である作動ピン１８が挿通される作動ピン孔（図示せず）が設けられている。第２ヒンジピン挿通孔と支持部材３の両側板３２の第２ヒンジピン孔３６とが孔合わせされてこれら孔３６に第２ヒンジピン１６が挿通されることによって、リフト部材４と支持部材３とが第２ヒンジピン１６を軸に互いに回動可能に連結されている。また、両側板４２の作動ピン孔に作動ピン１８が挿通されて固定されている。   A second hinge pin insertion hole (not shown) is provided at a position closer to the upper plate 41 than the center of one end of the lift member 4 (front end (end opposite to the mounting member 2)) An operation pin hole (not shown) through which the operation pin 18 as an operation member is inserted is provided at the other end side from the second hinge pin insertion hole and at a position opposite to the upper plate 41 side from the center. ing. The second hinge pin insertion hole and the second hinge pin hole 36 of the both side plates 32 of the support member 3 are aligned with each other, and the second hinge pin 16 is inserted into the hole 36, so that the lift member 4 and the support member 3 are connected to each other. Two hinge pins 16 are pivotally connected to each other. Further, the operating pin 18 is inserted and fixed in the operating pin hole of the both side plates 42.

また、上板４１の後端部近傍に、原稿圧着板１２の水平位置を調節する水平位置調節手段４５を設けるようにしてもよい。水平位置調節手段４５は、例えば、上板４１の後端部近傍であってその幅方向の中央部（略中央部を含む。）に設けられた調節ネジ４６と締結ナット４７とからなる。締結ナット４７が上板４１に固定され、この締結ナット４７に調節ネジ４６が螺合されると共に、調節ネジ４６の先端が支持部材３の上板３１に当接して、調節ネジ４６の調節により支持部材３とリフト部材４との間隔が調節されて、原稿圧着板１２の水平位置が調節されるようになっている。   Further, a horizontal position adjusting means 45 for adjusting the horizontal position of the original cover 12 may be provided in the vicinity of the rear end portion of the upper plate 41. The horizontal position adjusting means 45 includes, for example, an adjusting screw 46 and a fastening nut 47 provided in the vicinity of the rear end portion of the upper plate 41 and in the central portion (including the substantially central portion) in the width direction. A fastening nut 47 is fixed to the upper plate 41, and an adjustment screw 46 is screwed onto the fastening nut 47, and the tip of the adjustment screw 46 abuts on the upper plate 31 of the support member 3, and the adjustment screw 46 is adjusted. The horizontal position of the original cover 12 is adjusted by adjusting the distance between the support member 3 and the lift member 4.

コンプレッションスプリング５は、原稿圧着板１２を開成方向に回転付勢すると共に、リフト部材４を支持部材３と重なり合う方向へ付勢し、かつ、原稿圧着板１２が任意の回動角度以下のとき、原稿圧着板１２を付勢する弾力が原稿圧着板１２のモーメントより小さいものである。なお、本発明において開成方向とは、原稿圧着板１２を回転させる際に原稿圧着板１２が機器本体１１の上部のコンタクトガラス１３から離間する方向をいう。本発明において閉成方向とは、開成方向とは反対の方向で原稿圧着板１２を回転させる際に原稿圧着板１２がコンタクトガラス１３に近づく方向をいう。本発明における回動角度とは、機器本体１１の上面であるコンタクトガラス１３面に対する原稿圧着板１２の角度である。本発明における任意の回動角度とは、コンプレッションスプリング５の弾力により任意に設定されるもので、例えば、コンプレッションスプリング５による原稿圧着板１２を付勢する弾力が原稿圧着板１２のモーメントより小さくなる角度で、例えば略２０°以下の角度である。   The compression spring 5 urges the document crimping plate 12 to rotate in the opening direction, urges the lift member 4 in a direction overlapping the support member 3, and when the document crimping plate 12 is below an arbitrary rotation angle. The elasticity for urging the original cover 12 is smaller than the moment of the original cover 12. In the present invention, the opening direction refers to a direction in which the original cover 12 is separated from the contact glass 13 on the upper part of the apparatus body 11 when the original cover 12 is rotated. In the present invention, the closing direction refers to a direction in which the original cover 12 approaches the contact glass 13 when the original cover 12 is rotated in a direction opposite to the opening direction. In the present invention, the rotation angle is an angle of the original cover 12 with respect to the surface of the contact glass 13 that is the upper surface of the device body 11. The arbitrary rotation angle in the present invention is arbitrarily set by the elastic force of the compression spring 5. For example, the elastic force that urges the original pressure plate 12 by the compression spring 5 is smaller than the moment of the original pressure plate 12. The angle is, for example, approximately 20 ° or less.

コンプレッションスプリング５は、その個数は特に限定されず、１つでも２つ以上でもよく、また、２つ以上を並列させてもよく、例えば、図示例では、径の大きなコンプレッションスプリング５１の中に径の小さなコンプレッションスプリング５２を入れたものを２組並列させてもよい。すなわち、コンプレッションスプリング５は、原稿圧着板１２を開成方向に回転付勢すると共に、原稿圧着板１２が所定の回動角度（例えば、略２０°）以下のとき、原稿圧着板１２を付勢する弾力が原稿圧着板１２のモーメントより小さくなるならばどのように構成してもよい。   The number of the compression springs 5 is not particularly limited, and may be one, two or more, and two or more may be arranged in parallel. For example, in the illustrated example, the diameter of the compression spring 5 is within the compression spring 51 having a large diameter. Two sets of compression springs 52 having a small size may be arranged in parallel. That is, the compression spring 5 urges the document crimping plate 12 to rotate in the opening direction, and urges the document crimping plate 12 when the document crimping plate 12 is less than a predetermined rotation angle (for example, approximately 20 °). Any configuration may be used as long as the elasticity is smaller than the moment of the original cover 12.

第１スライダー６及び第２スライダー７は、それぞれ断面矩形の有底筒体状に形成されている。第１スライダー６及び第２スライダー７は、２組のコンプレッションスプリング５の端部をそれぞれ個別に収容するスプリング収容部６５、７５が２つそれぞれ設けられている。操作プレート８１が設けられている第１スライダー６のスプリング収容部６５の内形は、円形以外の形状、例えば、楕円形、三角形、矩形、５角形以上の多角形などの非円形（図示例では８角形（図４参照。））に形成されている。第２スライダー７のスプリング収容部７５の内形は、第１スライダー６のスプリング収容部６５と同じ形状等の非円形に形成してもよいし、円形に形成してもよい。また、第１スライダー６の一方のスプリング収容部６５を形成する底部には、その略同軸上に円形の貫通孔６１が設けられている。   The first slider 6 and the second slider 7 are each formed in a bottomed cylindrical shape having a rectangular cross section. The first slider 6 and the second slider 7 are each provided with two spring accommodating portions 65 and 75 that individually accommodate the ends of the two sets of compression springs 5. The inner shape of the spring accommodating portion 65 of the first slider 6 on which the operation plate 81 is provided is a non-circular shape such as an ellipse, a triangle, a rectangle, a pentagon or more polygon (in the illustrated example). It is formed in an octagon (see FIG. 4). The inner shape of the spring accommodating portion 75 of the second slider 7 may be formed in a non-circular shape such as the same shape as the spring accommodating portion 65 of the first slider 6, or may be formed in a circular shape. In addition, a circular through hole 61 is provided on the bottom of the first slider 6 that forms one spring accommodating portion 65 substantially on the same axis.

第１スライダー６及び第２スライダー７は、互いの開口部が向き合うと共にこれらの間にコンプレッションスプリング５の両端部が収容された状態で支持部材３の収容部３４にそれぞれ個別に摺動可能に収装された状態で挿入されている。第１スライダー６及び第２スライダー７は、取付部材２の底板２１と支持部材３（上板３１）が略平行になっているとき（例えば機器本体１１の上面のコンタクトガラス１３上に原稿圧着板１２を密着させたとき（原稿圧着板１２が閉成位置にあるとき））、支持部材３の収容部３４内に嵌合される長さで形成されている。   The first slider 6 and the second slider 7 are individually slidably accommodated in the accommodating portion 34 of the support member 3 with the openings facing each other and the both ends of the compression spring 5 accommodated therebetween. It is inserted in the state of wearing. The first slider 6 and the second slider 7 are arranged such that when the bottom plate 21 of the mounting member 2 and the support member 3 (upper plate 31) are substantially parallel (for example, the original pressure plate on the contact glass 13 on the upper surface of the device body 11). When the sheet 12 is brought into close contact (when the document crimping plate 12 is in the closed position), it is formed with a length that fits into the accommodating portion 34 of the support member 3.

第１スライダー６がコンプレッションスプリング５の弾力によって作動ピン１８を押圧して、支持部材３とリフト部材４とが重なり合うように付勢される。すなわち、コンプレッションスプリング５の弾力によってリフト部材４の上板４１が支持部材３の上板３１に当接又は近接するようになっている。このとき、上板４１が例えばコンタクトガラス１３に対して略平行になるようになっていることが好ましい。なお、支持部材３の上板３１にリフト部材４の上板４１を当接又は近接するようにしてもよい。   The first slider 6 presses the operating pin 18 by the elasticity of the compression spring 5 and is urged so that the support member 3 and the lift member 4 overlap each other. That is, the upper plate 41 of the lift member 4 is brought into contact with or close to the upper plate 31 of the support member 3 by the elasticity of the compression spring 5. At this time, it is preferable that the upper plate 41 is substantially parallel to the contact glass 13, for example. The upper plate 41 of the lift member 4 may be brought into contact with or close to the upper plate 31 of the support member 3.

第２スライダー７の底部（閉塞部ということがある。）の外表面の略中央部には、突部７１が設けられている。この突部７１の下方は漸次傾斜された傾斜部７２として形成されている。この第２スライダー７の底部の外表面の突部７１及び傾斜部７２がカムとして形成されている。すなわち、閉成位置にある原稿圧着板１２（図１参照。）をコンタクトガラス１３から離間する方向（上方）に第１ヒンジピン１５を軸に回転させると、受圧ローラ１７に当接する箇所が突部７１から傾斜部７２へと徐々に摺動すると共に、第２スライダー７がコンプレッションスプリング５によって支持部材３内を後端部側へと押圧されて摺動し、コンプレッションスプリング５が徐々に伸びる（図２参照。）。そして、原稿圧着板１２が最大使用開放角度（例えば、略６０°〜略７０°）になると、その開閉が原稿圧着板開閉規制機構（図示せず）によって規制されるようになっている。なお、図１及び図２中、符号７３は延出片を示している。この延出片７３は、例えば、第２スライダー７の幅より若干短い寸法の幅で形成されていることが好ましい。これにより、受圧ローラ１７の外表面に第２スライダー７との摺接を円滑にする潤滑用のグリスが塗布されていても、延出片７３が受圧ローラ１７の外周の大部分を覆うために、原稿圧着板１２によって押圧されることによって変形した原稿の端部が受圧ローラ１７へはみ出しても、この端部がグリスが塗布されている受圧ローラ１７に接触して汚れてしまうことはないようになっている。   A protrusion 71 is provided at a substantially central portion of the outer surface of the bottom (sometimes referred to as a closed portion) of the second slider 7. A lower portion of the protrusion 71 is formed as an inclined portion 72 that is gradually inclined. A protrusion 71 and an inclined portion 72 on the outer surface of the bottom portion of the second slider 7 are formed as cams. That is, when the original pressing plate 12 (see FIG. 1) in the closed position is rotated about the first hinge pin 15 in the direction away from the contact glass 13 (upward), the portion that contacts the pressure receiving roller 17 is a protrusion. The second slider 7 is slid while being slid gradually from 71 to the inclined portion 72, while the second spring 7 is pressed and slid by the compression spring 5 toward the rear end side, and the compression spring 5 gradually extends (see FIG. 2). When the original crimping plate 12 reaches a maximum use opening angle (for example, approximately 60 ° to approximately 70 °), its opening / closing is regulated by an original crimping plate opening / closing regulating mechanism (not shown). In FIGS. 1 and 2, reference numeral 73 denotes an extended piece. For example, the extension piece 73 is preferably formed with a width slightly shorter than the width of the second slider 7. As a result, even if the grease for lubrication for smooth sliding contact with the second slider 7 is applied to the outer surface of the pressure receiving roller 17, the extending piece 73 covers most of the outer periphery of the pressure receiving roller 17. Even if the end portion of the document deformed by being pressed by the document pressing plate 12 protrudes to the pressure receiving roller 17, the end portion does not come into contact with the pressure receiving roller 17 to which the grease is applied and is not contaminated. It has become.

弾力調節手段８は、コンプレッションスプリング５の弾力を調節するものである。弾力調節手段８は、全てのコンプレッションスプリング５の弾力を調節するようにしてもよいし、任意のコンプレッションスプリング５の両端部や一方の端部に設けるようにしてもよく、例えば、２組のコンプレッションスプリング５の一方のコンプレッションスプリング５の一方の端部（第１スライダー６側の端部）にのみ設けるようにしてもよい。弾力調節手段８は、一対のスライダー６、７の少なくとも一方のスライダー例えば第１スライダー６内に回転可能に設けられ、コンプレッションスプリング５内に延びるアジャスト部８２を有する操作プレート８１と、この操作プレート８１のアジャスト部８２に軸方向に移動可能に設けられ、軸回りに回転しないと共にコンプレッションスプリング５の端部が当接するアジャストプレート８４と、操作プレート８１に設けられ、第１スライダー６に設けられた貫通孔６１から外部に露出される操作部８３とを備えてなる。   The elasticity adjusting means 8 adjusts the elasticity of the compression spring 5. The elasticity adjusting means 8 may adjust the elasticity of all the compression springs 5 or may be provided at both ends or one end of any compression spring 5, for example, two sets of compressions. You may make it provide only in the one edge part (edge part by the side of the 1st slider 6) of one compression spring 5 of the spring 5. FIG. The elasticity adjusting means 8 is rotatably provided in at least one of the pair of sliders 6, 7, for example, the first slider 6, and has an operation plate 81 having an adjusting portion 82 extending into the compression spring 5, and the operation plate 81. An adjustment plate 84 is provided in the adjustment plate 82 so as to be movable in the axial direction, does not rotate around the axis and contacts the end of the compression spring 5, and a through-hole provided in the operation plate 81 and provided in the first slider 6. And an operation portion 83 exposed to the outside through the hole 61.

操作プレート８１は、図１〜図３及び図５に示すように、例えば、第１スライダー６のスプリング収容部６５内で回転可能な円板状に形成されている。この操作プレート８１の一方の面には、その軸方向であってコンプレッションスプリング５内に延びるアジャスト部８２が設けられている。アジャスト部８２は、例えば、棒状に形成され、この外周にネジ溝が設けられている。また、操作プレート８１の他方の面には、その軸方向に延びる操作部８３が設けられている。操作部８３は、第１スライダー６の貫通孔６１に回転可能に嵌合される円形に突出して形成されている。操作部８３の突出長さは、貫通孔６１を貫通する寸法であってもよいし、貫通孔６１より短い寸法であってもよい。操作部８３の先端面には、例えば、ドライバー等の工具により操作プレート８１を第１スライダー６内で簡単に回転させることができる操作凹部８３ａが設けられている。   As shown in FIGS. 1 to 3 and 5, the operation plate 81 is formed in a disk shape that can rotate within the spring accommodating portion 65 of the first slider 6, for example. On one surface of the operation plate 81, an adjustment portion 82 is provided that extends in the compression spring 5 in the axial direction. The adjustment part 82 is formed in a rod shape, for example, and a screw groove is provided on the outer periphery thereof. An operation portion 83 extending in the axial direction is provided on the other surface of the operation plate 81. The operation portion 83 is formed to project in a circular shape that is rotatably fitted in the through hole 61 of the first slider 6. The projecting length of the operation portion 83 may be a dimension that penetrates the through hole 61 or may be a dimension that is shorter than the through hole 61. An operation concave portion 83a is provided on the distal end surface of the operation portion 83. For example, the operation plate 81 can be easily rotated in the first slider 6 by a tool such as a screwdriver.

アジャストプレート８４は、図３及び図６に示すように、第１スライダー６のスプリング収容部６５内でその軸方向に移動可能であるが、軸回りに回転しない形状、例えば、スプリング収容部６５より若干小さな８角形状の板状に形成されている。すなわち、アジャストプレート８４は、スプリング収容部６５に嵌合されて軸回りに回転しないと共に、スプリング収容部６５の軸方向に移動可能な形状に形成されている。このアジャストプレート８４の略中央部には、アジャスト部８２に螺合するアジャスト孔８４ａを有する螺合部８４ｂが突出されており、操作プレート８１が回転することによりアジャストプレート８４がアジャスト部８２に対してその軸方向に移動するようになっている。このアジャストプレート８４にコンプレッションスプリング５の端部が当接しており、アジャストプレート８４の位置が変わることによりコンプレッションスプリング５の弾力が調節されるようになっている。   As shown in FIGS. 3 and 6, the adjustment plate 84 is movable in the axial direction within the spring accommodating portion 65 of the first slider 6, but has a shape that does not rotate around the axis, for example, from the spring accommodating portion 65. It is formed in a slightly small octagonal plate shape. That is, the adjustment plate 84 is formed in a shape that is fitted in the spring accommodating portion 65 and does not rotate around the axis, and is movable in the axial direction of the spring accommodating portion 65. A threaded portion 84b having an adjustment hole 84a threadedly engaged with the adjustment portion 82 protrudes at a substantially central portion of the adjustment plate 84, and the adjustment plate 84 moves relative to the adjustment portion 82 when the operation plate 81 rotates. It moves in the axial direction. The end of the compression spring 5 abuts on the adjustment plate 84, and the elasticity of the compression spring 5 is adjusted by changing the position of the adjustment plate 84.

また、コンプレッションスプリング５内に、ダンパー装置（図示せず）を設けるようにしてもよい。このダンパー装置は、原稿圧着板１２が閉成方向に回転したとき、原稿圧着板１２の任意の回動角度以下の特定の回動角度以下（例えば略１０°以下）においてのみその原稿圧着板１２の回転速度を低減させるように動作するものである。ダンパー装置は、例えば、オイルダンパ装置等である。   Further, a damper device (not shown) may be provided in the compression spring 5. In this damper device, when the original cover 12 is rotated in the closing direction, the original cover 12 is only at a specific rotation angle or less (for example, approximately 10 ° or less) below an arbitrary rotation angle of the original cover 12. It operates so as to reduce the rotation speed. The damper device is, for example, an oil damper device.

次に、本発明に係る原稿圧着板開閉装置１及び事務機器１０の作用を説明する。   Next, the operation of the original cover 1 and the office machine 10 according to the present invention will be described.

原稿圧着板１２は、機器本体１１が使用されていない状態では、図１に示すように、機器本体１１のコンタクトガラス１３に密着されている。コンタクトガラス１３上に原稿を載置するには、まず、リフト部材４が取り付けられている箇所とは反対側の原稿圧着板１２の端部又はその近傍等に設けられている把持部を持って、図２に示すように、原稿圧着板１２を上方に持ち上げる。すなわち、原稿圧着板１２を第１ヒンジピン１５を軸にのみ回転させてコンタクトガラス１３面を外部に露出させる。このように原稿圧着板１２を回転させるとき、原稿圧着板１２は、コンプレッションスプリング５の弾力によって開成方向に回転付勢されているので、重量を感じさせることなく開成方向に回転することができる。   The original cover 12 is in close contact with the contact glass 13 of the device body 11 as shown in FIG. 1 when the device body 11 is not used. In order to place a document on the contact glass 13, first, hold a grip portion provided at the end of the document crimping plate 12 on the side opposite to the portion where the lift member 4 is attached or in the vicinity thereof. As shown in FIG. 2, the original cover 12 is lifted upward. That is, the original cover 12 is rotated only about the first hinge pin 15 to expose the surface of the contact glass 13 to the outside. Thus, when the original cover 12 is rotated, the original cover 12 is urged to rotate in the opening direction by the elasticity of the compression spring 5, and thus can rotate in the opening direction without feeling weight.

露出したコンタクトガラス１３面上に原稿を載置した後、持ち上げた原稿圧着板１２を降ろす。すなわち、原稿圧着板１２をコンタクトガラス１３と接触する閉成方向に第１ヒンジピン１５を軸に回転させて下方に移動させて閉成状態にする。原稿圧着板１２が閉成状態になると、原稿が薄い紙である場合には、原稿圧着板１２によって原稿をコンタクトガラス１３上から浮き上がることなく確実にコンタクトガラス１３に密着させることができるので、原稿を良好に複写等することができる。すなわち、原稿圧着板１２とコンタクトガラス１３との間に光が入らないように原稿圧着板１２がコンタクトガラス１３に密着されて、原稿を良好に複写等することができる。   After placing the document on the exposed contact glass 13 surface, the lifted document pressing plate 12 is lowered. That is, the original crimping plate 12 is rotated about the first hinge pin 15 in the closing direction in contact with the contact glass 13 and moved downward to be in the closed state. When the original cover 12 is in a closed state, if the original is thin paper, the original can be securely brought into close contact with the contact glass 13 without being lifted from the contact glass 13 by the original cover 12. Can be copied well. That is, the original pressing plate 12 is brought into close contact with the contact glass 13 so that light does not enter between the original pressing plate 12 and the contact glass 13, and the original can be copied well.

また、原稿が例えば本のように厚さが厚い場合、原稿圧着板１２を閉成方向に回転させると、原稿の支持部材３側の端部又はその近傍に原稿圧着板１２の支持部材３の近傍の一部が接触し、原稿の支持部材３側の端部とは反対側の端部と原稿圧着板１２との間に空間が形成される。すなわち、原稿圧着板１２は浮いた状態となる。その浮いている原稿圧着板１２をコンタクトガラス１３側に押圧したり原稿圧着板１２の自重により、作動ピン１８が第１スライダー６を押圧してコンプレッションスプリング５の弾力に抗して第１スライダー６がコンプレッションスプリング５側に移動すると共に、原稿圧着板１２（リフト部材４）が第２ヒンジピン１６を軸に回転する。つまり、原稿の上部を覆うように原稿圧着板１２が移動する。例えば、その原稿の上部が平坦面である場合には、この上部に原稿圧着板１２が面接触する。その結果、厚さが厚い原稿が安定してコンタクトガラス１３に密着されることになる。よって、原稿圧着板１２は、原稿の厚さに関係なく原稿を安定してコンタクトガラス１３に密着することができ、原稿を良好に複写等することができる。   Further, when the original is thick like a book, for example, when the original pressing plate 12 is rotated in the closing direction, the supporting member 3 of the original pressing plate 12 is positioned at or near the end of the original supporting member 3 side. A part of the vicinity comes into contact, and a space is formed between the end of the document opposite to the end on the support member 3 side and the document crimping plate 12. That is, the original cover 12 is in a floating state. The floating document pressing plate 12 is pressed against the contact glass 13 side, or the operating pin 18 presses the first slider 6 due to the weight of the document pressing plate 12, and the first slider 6 resists the elasticity of the compression spring 5. Moves to the compression spring 5 side, and the original cover 12 (lift member 4) rotates around the second hinge pin 16 as an axis. That is, the original cover 12 moves so as to cover the upper part of the original. For example, when the upper part of the original is a flat surface, the original cover 12 is in surface contact with the upper part. As a result, a thick original is stably brought into close contact with the contact glass 13. Therefore, the original cover 12 can stably adhere the original to the contact glass 13 regardless of the thickness of the original, and can copy the original satisfactorily.

このような本発明に係る原稿圧着板開閉装置１及び事務機器１０では、弾力調節手段８が設けられているので、コンプレッションスプリング５の弾力を変化させて支持部材３の回転トルクを調節することができる。すなわち、ドライバー等の工具を操作部８３の操作凹部８３ａに係合させた後、この工具を軸周りに回転させると、この工具の回転に伴って第１スライダー６内に設けられている操作プレート８１が適宜回転する。すると、アジャスト部８２が回転してこのアジャスト部８２に対してアジャストプレート８４が第１スライダー６のスプリング収容部６５内をその軸方向に移動する。このアジャストプレート８４には、コンプレッションスプリング５の端部が当接されているために、このコンプレッションスプリング５の両端部間の長さが変わってコンプレッションスプリング５の弾力が変化する。例えば、操作プレート８１を一方の方向に回転させると、アジャストプレート８４が操作プレート８１に近づく方向に移動してバネ荷重が弱くなり、他方、操作プレート８１を他方の方向に回転させると、アジャストプレート８４が操作プレート８１から離れる方向に移動してバネ荷重が強くなる。このようにバネ荷重を変えることにより、トルクの調節を行うことができる。   In the original pressure plate opening / closing device 1 and the office equipment 10 according to the present invention, since the elasticity adjusting means 8 is provided, it is possible to adjust the rotational torque of the support member 3 by changing the elasticity of the compression spring 5. it can. That is, when a tool such as a screwdriver is engaged with the operation recess 83a of the operation unit 83 and then the tool is rotated around the axis, the operation plate provided in the first slider 6 is accompanied with the rotation of the tool. 81 rotates appropriately. Then, the adjusting portion 82 rotates and the adjusting plate 84 moves in the axial direction within the spring accommodating portion 65 of the first slider 6 with respect to the adjusting portion 82. Since the end portion of the compression spring 5 is brought into contact with the adjustment plate 84, the length between both end portions of the compression spring 5 changes, and the elasticity of the compression spring 5 changes. For example, when the operation plate 81 is rotated in one direction, the adjustment plate 84 moves in a direction approaching the operation plate 81 and the spring load becomes weak. On the other hand, when the operation plate 81 is rotated in the other direction, the adjustment plate 84 84 moves in a direction away from the operation plate 81, and the spring load is increased. The torque can be adjusted by changing the spring load in this way.

このように、操作プレート８１を回転させると、アジャスト部８２に対するアジャストプレート８４は回転することなく軸方向に移動するために、コンプレッションスプリング５は捩じれることなく両端部間の長さが変わってコンプレッションスプリング５の弾力が変化するので、トルクの調節を正確に行える。   As described above, when the operation plate 81 is rotated, the adjustment plate 84 with respect to the adjustment portion 82 moves in the axial direction without rotating. Therefore, the compression spring 5 is not twisted and the length between both ends is changed. Since the elasticity of the spring 5 changes, the torque can be adjusted accurately.

また、操作部８３が第１スライダー６の貫通孔６１から外部に露出されているために、操作プレート８１の操作が簡単であるので、トルクの調節を簡単に行えることになる。また、操作部８３を操作する貫通孔６１が原稿圧着板開閉装置１の先端部である第１スライダー６の端部（閉塞部）に設けられているので、操作性がよく、一層容易にトルクの調節を行える。   In addition, since the operation portion 83 is exposed to the outside from the through hole 61 of the first slider 6, the operation of the operation plate 81 is easy, so that the torque can be easily adjusted. Further, since the through-hole 61 for operating the operation portion 83 is provided at the end portion (blocking portion) of the first slider 6 which is the front end portion of the document crimping plate opening / closing device 1, the operability is improved and the torque is more easily Can be adjusted.

したがって、本発明に係る原稿圧着板開閉装置１及び事務機器１０は、トルクの調節を簡単にしかも正確に行える。これにより、ハネや中折れを簡単にしかも確実に防止することができる。すなわち、バネ荷重が強すぎると、原稿圧着板１２を開成方向に回転させるとき、その回転途中でコンプレッションスプリング５の弾力により原稿圧着板１２が自動的に回転する、いわゆるハネ現象が発生することがあるが、バネ荷重を適切に調節することができ、ハネを簡単にしかも確実に防止することができる。また、バネ荷重が弱すぎると、原稿圧着板１２を閉成方向に回転させるとき、その回転途中でコンプレッションスプリング５の弾力に抗して第２ヒンジピン１６を軸に支持部材３に対してリフト部材４が回転する、いわゆる中折れ現象が発生することがあるが、バネ荷重を適切に調節することができ、中折れを簡単にしかも確実に防止することができる。   Therefore, the document crimping plate opening / closing device 1 and the office machine 10 according to the present invention can easily and accurately adjust the torque. As a result, it is possible to easily and reliably prevent breakage and breakage. That is, if the spring load is too strong, when the original cover 12 is rotated in the opening direction, a so-called sag phenomenon may occur in which the original cover 12 is automatically rotated by the elasticity of the compression spring 5 during the rotation. However, the spring load can be adjusted appropriately, and it is possible to easily and reliably prevent splashes. On the other hand, if the spring load is too weak, when the original pressure plate 12 is rotated in the closing direction, the lift member against the support member 3 with the second hinge pin 16 as an axis against the elasticity of the compression spring 5 during the rotation. Although the so-called half-folding phenomenon that the 4 rotates may occur, the spring load can be adjusted appropriately, and the middle folding can be prevented easily and reliably.

以上説明したように本発明に係る原稿圧着板開閉装置は、スライダー内に回転可能に設けられ、アジャスト部を有する操作プレートと、アジャスト部に軸方向に移動可能に設けられ、軸回りに回転しないと共にコンプレッションスプリングの端部が当接するアジャストプレートと、操作プレートに設けられ、スライダーに設けられた貫通孔から外部に露出されて操作プレートを回転させる操作部とを備えたことから、スライダーの貫通孔から外部に露出されている操作部によって操作プレートを回転させることができると共に、アジャストプレートは回転することなく軸方向に移動して、コンプレッションスプリングが捩じれることなくコンプレッションスプリングの弾力が変化するので、トルクの調節を簡単にしかも正確に行えることから、特に複写機、印刷機、ファクシミリ、スキャナー等の事務機器の原稿圧着板開閉装置として好適に用いられるものである。   As described above, the document pressing plate opening / closing device according to the present invention is rotatably provided in the slider, is provided with the operation plate having the adjustment portion, and is provided in the adjustment portion so as to be movable in the axial direction, and does not rotate around the axis. And an adjusting plate with which the end of the compression spring abuts, and an operating portion provided on the operating plate and exposed to the outside from the through hole provided on the slider to rotate the operating plate.
