Description

本考案は、例えば複合機や印刷機などの事務機器の装置本体に対して、原稿圧着板などを開閉可能に取り付ける際に用いて好適な、原稿圧着板開閉装置並びにこの原稿圧着板開閉装置を用いた事務機器に関する。 The present invention provides a document crimping plate opening / closing device and this document crimping plate opening / closing device, which are suitable for use when attaching a document crimping plate or the like to the main body of an office device such as a multifunction device or a printing machine so as to be openable / closable. Regarding the office equipment used.

従来、複合機や印刷機などの事務機器に用いられる原稿圧着板開閉装置として、装置本体側へ取り付けられる取付板とこの取付板の両側より立ち上げた両側板とを有する取付部材と、背板とこの背板より垂下させた両側板を有し、この両側板を前記取付部材の前記両側板へヒンジシャフトを介して回転可能に取り付けた支持部材と、背板とこの背板より垂下させた両側板を有し、前記支持部材の前記両側板の自由端側にリフトシャフトを介して回転可能に取り付けたリフト部材と、前記取付部材側の両側板間に取り付けた受圧部材と、この受圧部材にカム部を当接させて前記支持部材内部に摺動可能に設けられたカムスライダーと、前記支持部材内部の自由端側に摺動可能に設けられたスプリング受け部材と、このスプリング受け部材に当接し、前記リフト部材の前記両側板間に取り付けられた作動部材と、前記カムスライダーと前記スプリング受け部材との間に弾設させることにより、前記リフト部材を前記支持部材と重なり合う方向へ回転付勢させつつ前記支持部材を前記原稿圧着板の開成方向へ回転付勢させる弾性手段と、前記支持部材の内壁部の中央部と前記スプリング受け部材との間に設けられた一本のフリクション凸条部からなるブレーキ手段を有するものが、下記特許文献1に示したように公知である。 Conventionally, as a document crimping plate opening / closing device used for office equipment such as a compound machine and a printing machine, a mounting member having a mounting plate mounted on the device main body side and both side plates raised from both sides of the mounting plate, and a back plate. A support member having both side plates hung from the back plate, and the both side plates rotatably attached to the both side plates of the mounting member via a hinge shaft, and a back plate and the back plate hung down from the back plate. A lift member having both side plates and rotatably attached to the free end side of the both side plates of the support member via a lift shaft, a pressure receiving member attached between the both side plates on the mounting member side, and the pressure receiving member. A cam slider provided so as to be slidable inside the support member, a spring receiving member slidably provided on the free end side inside the support member, and the spring receiving member. The lift member is rotated in a direction in which it overlaps with the support member by abutting and causing the actuating member attached between the both side plates of the lift member to be repelled between the cam slider and the spring receiving member. An elastic means for rotationally urging the support member in the opening direction of the document crimping plate while urging the support member, and a single friction ridge provided between the central portion of the inner wall portion of the support member and the spring receiving member. Those having a braking means including parts are known as shown in Patent Document 1 below.

しかしながら、この特許文献1に記載された原稿圧着板開閉装置は、ブレーキ手段を構成するフリクション凸条部が細く、支持部材の内壁部の中央部に1本しか設けられていないため、必要なフリクショントルクを得るため、このフリクション凸条部の高さを高くする必要があった。そうすると、このカムスライダーと支持部材の間に、それなりの遊びを設ける必要があり、ブレーキ手段が動作しない領域においては、所謂がたが生じ、原稿圧着板開閉装置のスムーズな操作が阻害されるという問題があった。 However, in the document crimping plate opening / closing device described in Patent Document 1, the friction ridge portion constituting the braking means is thin, and only one is provided in the central portion of the inner wall portion of the support member, so that necessary friction is required. In order to obtain torque, it was necessary to increase the height of this friction ridge. Then, it is necessary to provide a certain amount of play between the cam slider and the support member, and in the region where the braking means does not operate, so-called rattling occurs, which hinders the smooth operation of the document crimping plate opening / closing device. There was a problem.

また、従来公知のものは、フリクショントルクを得るために、ヒンジシャフトと支持部材の両側板の間に、当該ヒンジシャフトを挿通させてフリクションプレートやスプリングワッシャーを重ね合わせて設け、ヒンジシャフトの端部をかしめて構成したフリクッション発生手段を設けていたため、部品点数が多くコストダウンの障害となっていた。 Further, in the conventionally known one, in order to obtain friction torque, the hinge shaft is inserted between the hinge shaft and both side plates of the support member, and a friction plate and a spring washer are provided so as to overlap each other, and the end portion of the hinge shaft is squeezed. Since the friction cushion generating means was provided, the number of parts was large, which was an obstacle to cost reduction.

さらに、従来公知の弾性手段を用いた原稿圧着板開閉装置にあっては、原稿圧着板の全開閉角度において、支持部材の回転動作を制御して原稿圧着板の操作性の向上を図ったものは見当たらない。 Further, in the document crimping plate opening / closing device using a conventionally known elastic means, the rotation operation of the support member is controlled at all the opening / closing angles of the document crimping plate to improve the operability of the document crimping plate. Is not found.

なお、この作動部材9は、リフト部材6の先端側に設けた図示してない頂板から一体、或は別体に設けられてもよい。また、後述する実施例3の図24に示したように、本考案は、リフト部材を省略した原稿圧着板開閉装置A3にも実施が可能である。請求項1は、この場合を想定している。 The operating member 9 may be provided integrally or separately from the top plate (not shown) provided on the tip end side of the lift member 6. Further, as shown in FIG. 24 of Example 3 described later, the present invention can also be implemented in the document crimping plate opening / closing device A3 in which the lift member is omitted. Claim 1 assumes this case.

リフト部材6の背板6aには、前記原稿圧着板m2が取り付けられると共に、この背板6aには、その後端部側に、当該背板6aにネジ着され調節ネジ7aとこの調節ネジ7aにネジ着されたナット7bからなる高さ調節手段7が設けられている。この高さ調節手段7は、原稿圧着板m2の原稿載置台m3(コンタクトガラス)に対する高さを微調整して、原稿圧着板m2が均等に原稿載置台m3の上面へ圧接するようにするためのものである。支持部材2の両側板2b、2bには、その際に用いる目盛2hが刻設されている。 The document crimping plate m2 is attached to the back plate 6a of the lift member 6, and the back plate 6a is screwed to the back plate 6a on the rear end side to the adjusting screw 7a and the adjusting screw 7a.

Of the support member 2 through which the lift shaft 4 is inserted and the mounting holes 2f, 2f, 6d, and 6d provided in the lift member 6 (only one of them is displayed), the one on the support member 2 side is the large diameter portion of the lift shaft 4. Although it has a circular shape that matches the outer diameter, the mounting holes 6d and 6d of the lift member 6 have a dented shape in which large and small circular holes with two centers overlap, and the small diameter part is the small diameter part of the lift shaft 6. It is crimped after being engaged with. The mounting holes 6e and 6e provided in the lift member 6 through which the operating member 9 is inserted also have a daruma shape in which large and small circular holes having two centers overlap each other, and the small diameter portion engages with the small diameter portion of the operating member 9. It is crimped after being made to. In each case, the E-ring and the like are omitted to facilitate the attachment of the lift shaft 4 and the operating member 9, and the cost is reduced. The mounting holes 6d and 6d for mounting the lift shaft 4 and the mounting holes 6e and 6e for mounting the operating member 9 have small diameter portions in opposite directions, and the mounting holes 6d and 6d for mounting the lift shaft 4 have small diameter portions. It faces slightly downward. This is because the elasticity of the elastic means 12 acting on the operating member 9 receives a pressing force on the side provided with the small diameter portion.

なお、このリフトシャフト4は、これを2分割して支持部材2とリフト部材6のそれぞれの両側板2b、2bと6b、6b同士を連結するように構成することは可能であり、リフトシャフト4はこのような実施例も含んでいる。後述する実施例2のものも同様である。 The lift shaft 4 can be divided into two parts so as to connect the side plates 2b, 2b, 6b, and 6b of the support member 2 and the lift member 6, respectively, and the lift shaft 4 can be configured.

An actuating member can also be formed on the top plate. Further, the operating member 9 can be rotatably or fixedly attached between the side plates 6b and 6b of the lift member 6. Further, the operating member 9 can be attached to the outer periphery thereof by rotating or fixing a cylinder made of a resin or other material. The actuating member according to the present invention includes these examples. This also applies to that of Example 2.

次に、ブレーキ手段B1は、支持部材2の背板2aの下面側のヒンジシャフト3側に所定間隔を空けてほぼ平行に設けられた一対のフリクション凸条部5、5で構成されており、原稿圧着板m2の所定開閉角度範囲においてカムスライダー10の背部10hの平坦な圧接面10iと圧接することにより、ヒンジシャフト3を支点に回転する支持部材2に対してブレーキ作用を営むようになっている。各フリクション凸条部5、5の形状は、とくに図6の(c)に示したように、その始端部5a、5aと終端部5b、5bにそれぞれ中央部に向けてなだらかに高くなる傾斜部5c、5c・5d、5dが設けられ、中央部は平坦部5e、5eとなっている。各フリクション凸条部5、5の高さは、平坦部の部分で0.35mm程度である。各始端部5a、5aと終端部5b、5bの形状は、カムスライダー10の後端部側の縁部に対して平行、即ち支持部材2の両側板2b、2bに対して直交状態である。この始端部5a、5aと終端部5b、5bの形状は、半円形状或は尖頭形状とすることもできる。その他の実施例として、フリクション凸条部5を1本にしてその幅を広げたり、数をさらに増やすことを排除するものではないが、実施例のものが好適である。 Next, the brake means B1 is composed of a pair of friction ridges 5 and 5 provided substantially parallel to the hinge shaft 3 side on the lower surface side of the back plate 2a of the support member 2 at predetermined intervals. By pressing against the flat pressure contact surface 10i of the back portion 10h of the cam slider 10 within a predetermined opening / closing angle range of the document crimping plate m2, a braking action is applied to the support member 2 rotating around the hinge shaft 3 as a fulcrum. There is. As shown in FIG. 6 (c), the shapes of the friction ridges 5 and 5 are inclined portions that gradually increase toward the center at the start ends 5a and 5a and the end portions 5b and 5b, respectively. 5c, 5c, 5d, and 5d are provided, and the central portion is a flat portion 5e and 5e. The height of each friction ridge portion 5, 5 is about 0.35 mm in the flat portion. The shapes of the start end portions 5a and 5a and the end portions 5b and 5b are parallel to the edge portion on the rear end portion side of the cam slider 10, that is, orthogonal to the side plates 2b and 2b of the support member 2. The shape of the start end portions 5a and 5a and the end portions 5b and 5b may be a semicircular shape or a pointed shape. As another embodiment, it is not excluded that the friction ridge portion 5 is made into one to widen the width or further increase the number, but the one of the embodiment is preferable.

かかる実施例の場合、とくにカムスライダー10は、支持部材2の背板2aの内壁側と抱持片2c、2cとの間の寸法と、支持部材2の両側板2b、2bの内側の寸法より、約0.1mm程度小さく形成されている。これはブレーキ手段B1のフリクション凸条部5、5の厚さを考慮したものである。 In the case of such an embodiment, in particular, the cam slider 10 is based on the dimensions between the inner wall side of the back plate 2a of the support member 2 and the holding pieces 2c and 2c, and the inner dimensions of the side plates 2b and 2b of the support member 2. , It is formed as small as about 0.1 mm. This takes into consideration the thickness of the friction protrusions 5 and 5 of the braking means B1.

さらに、ブレーキ手段B1のフリクション凸条部5、5は、支持部材2の両側板2b、2bの側に設けることもできる。さらに、カムスライダー10は合成樹脂製であるので、このカムスライダー10側が変形することによって、フリクショントルクの全部或は一部を創出できるように構成することもできる。 Further, the friction ridges 5 and 5 of the braking means B1 can be provided on the side of the side plates 2b and 2b of the support member 2. Further, since the cam slider 10 is made of synthetic resin, it can be configured so that all or a part of the friction torque can be created by deforming the cam slider 10 side.

なお、受圧部材8は、実施例のものは金属製のピン状のものであり、一端部側を小径部に構成してあり、取付部材1の両側板1b、1bに設けた大小の取付孔1d、1eもそれに合わせて大小に形成してある。受圧部材8はその大径の部分は大径の取付孔1dに、小径の部分は小径の取付孔1eに挿入し、その各端部をかしめることによって、固着されているが、Eリングを用いて抜け止め規制しても良い。また、回転可能に両側板1b、1bへ取り付けるようにしても良い。さらに、受圧部材8はピン状でなくとも、断面凸形状を呈するように構成した板金製あるいは合成樹脂製の湾曲部材を、取付部材1の取付部材1b、1bの内側へ固着するようしても良い。さらに、この受圧部材8には、合成樹脂製、あるいは他の材料で構成した筒体を嵌めて固定したり、或は回転可能に取り付けることは任意である。受圧部材8は、これらの変形実施例を包含しており、これは実施例2のものも同様である。 The pressure receiving member 8 of the embodiment is a metal pin-shaped member, has a small diameter portion on one end side, and has large and small mounting holes provided in both side plates 1b and 1b of the mounting member 1. 1d and 1e are also formed to be large and small accordingly. The pressure receiving member 8 is fixed by inserting the large-diameter portion into the large-diameter mounting hole 1d and the small-diameter portion into the small-diameter mounting hole 1e and crimping each end thereof. It may be used to prevent it from coming off. Further, it may be rotatably attached to both side plates 1b and 1b. Further, even if the pressure receiving member 8 is not pin-shaped, a curved member made of sheet metal or synthetic resin configured to exhibit a convex cross section may be fixed to the inside of the mounting members 1b and 1b of the mounting member 1. good. Further, it is optional that the pressure receiving member 8 is fitted and fixed with a cylinder made of synthetic resin or other material, or is rotatably attached. The pressure receiving member 8 includes these modified examples, and this is the same as that of the second embodiment.

次に、上記実施例1に係る原稿圧着板開閉装置A1の動作について説明する。今、図2と図9に示したように、想像線で示した原稿圧着板m2を閉じた状態においては、主として当該原稿圧着板m2の重量により、弾性手段12の弾力に抗して原稿圧着板m2は閉じられ、安定した閉成状態を保っている。なお、ここのところは、図示したように、受圧部材8が原稿圧着板m2の閉成時に下り傾斜10dに当接させることにより、原稿圧着板m2を閉成方向へ回転付勢させることもできる。いずれにしても、原稿圧着板m2の閉成状態において、受圧部材8はその軸方向の側部をカムスラー10のカム部10fと当接させており、圧縮された状態の弾性手段12の押圧力を受けている。 Next, the operation of the document crimping plate opening / closing device A1 according to the first embodiment will be described. Now, as shown in FIGS. 2 and 9, in the state where the document crimping plate m2 shown by the imaginary line is closed, the weight of the document crimping plate m2 mainly causes the document crimping against the elasticity of the elastic means 12. The plate m2 is closed and maintains a stable closed state. At this point, as shown in the drawing, the original crimping plate m2 can be rotationally urged in the closing direction by bringing the pressure receiving member 8 into contact with the downward inclination 10d when the original crimping plate m2 is closed. .. In any case, in the closed state of the document crimping plate m2, the pressure receiving member 8 has its axial side portion in contact with the cam portion 10f of the cam sler 10, and the pressing force of the elastic means 12 in the compressed state. Is receiving.

次に、図2と図9に示した状態から原稿圧着板m2を開くと、カムスライダー10のカム部10fの受圧部材8に対する当接位置が、該カム部10fの上り傾斜部10cの高い方から低い方へ圧接状態を維持させたまま移動することから、弾性手段12の弾力により原稿圧着板m2は、その本来の重量を減殺された状態で開かれる。開いた原稿圧着板m2より手を離すと、受圧部材8の当接位置が弾性手段12によって一方向へ摺動を付勢されているカムスライダー10の上り傾斜部10cの高い方へ移動するフリクション抵抗に遭遇することにより、原稿圧着板m2が支持部材2を介してヒンジシャフト3の周りに発生させる回転モーメントと、弾性手段12の弾力と、カムスライダー10のカム部10fに当接している受圧部材8とによって創出される回転トルクが均衡する。実施例のものは原稿圧着板m2の20度以上の開成角度で、当該原稿圧着板m2を安定停止保持することができる。 Next, when the document crimping plate m2 is opened from the state shown in FIGS. 2 and 9, the contact position of the cam portion 10f of the cam slider 10 with respect to the pressure receiving member 8 is the higher of the ascending inclined portion 10c of the cam portion 10f. Since the original crimping plate m2 is moved from the lower side to the lower side while maintaining the pressure contact state, the original weight of the original crimping plate m2 is opened in a state of being reduced by the elasticity of the elastic means 12. When the hand is released from the open document crimping plate m2, the contact position of the pressure receiving member 8 moves to the higher side of the ascending inclined portion 10c of the cam slider 10 whose sliding is urged in one direction by the elastic means 12. The rotational moment generated by the document crimping plate m2 around the hinge shaft 3 via the support member 2 by encountering the resistance, the elasticity of the elastic means 12, and the pressure received in contact with the cam portion 10f of the cam slider 10. The rotational torque created by the member 8 is balanced. In the embodiment, the original crimping plate m2 can be stably stopped and held at an opening angle of 20 degrees or more of the original crimping plate m2.

原稿圧着板m2が図2に示した閉成状態から20度まで開かれると、摺動するカムスライダー10の上部後端部がブレーキ手段B1のフリクション凸条部5、5の傾斜部5c、5cに当接し始めることから、ブレーキ作用が生じる。この際に、フリクション凸条部5、5のカムスライダー10側には平坦部5e、5eに向けて徐々に高くなるなだらかな傾斜部5c、5cが形成されているので、カムスライダー10のフリクション凸条部5、5に対する接触はがくんとした衝撃を与えるものではなく、滑らかになされることになり、操作性の向上が図られることになる。このブレーキ作用は原稿圧着板m2の開成角度が60度に達するまで続き、60度を超えると、図示はしてないが、カムスライダー10は受圧部材8から離れ、実施例では、カムスライダー10のストッパー部10e側がヒンジシャフト3に当接して、スライドが阻止される構成である。 When the document crimping plate m2 is opened up to 20 degrees from the closed state shown in FIG. 2, the upper rear end of the sliding cam slider 10 is displaced by the friction protrusions 5 and 5 of the braking means B1 and the inclined portions 5c and 5c. The braking action occurs because it starts to come into contact with the. At this time, since the gently inclined portions 5c and 5c gradually increasing toward the flat portions 5e and 5e are formed on the cam slider 10 side of the friction ridges 5 and 5, the friction convex of the cam slider 10 is formed. The contact with the strips 5 and 5 does not give a sharp impact, but is smoothed, and the operability is improved. This braking action continues until the opening angle of the document crimping plate m2 reaches 60 degrees, and when it exceeds 60 degrees, the cam slider 10 is separated from the pressure receiving member 8 although not shown, and in the embodiment, the cam slider 10 The stopper portion 10e side comes into contact with the hinge shaft 3 to prevent the slide.

開いた原稿圧着板m2を閉じる際には、当該原稿圧着板m2は受圧部材8が弾性手段12の弾力に抗してカムスライダー10のカム部10fの高い方へスライドする際の抵抗に遭遇するが、手による原稿圧着板m2に対する押圧力と、原稿圧着板m2の重量と、慣性力により閉じられ、所定の閉成角度、例えば10度になると、原稿圧着板m2の閉成方向のモーメントが勝り始め、手を離しても自動的に閉じられることになるが、本考案に係るものは、ダンパー手段13が動作して、緩衝作用を行うので、原稿圧着板m2が急激に閉じられて大きな音を立てたり、手を挟んでしまう心配がないものである。 When closing the open document crimping plate m2, the document crimping plate m2 encounters resistance when the pressure receiving member 8 slides toward the higher side of the cam portion 10f of the cam slider 10 against the elasticity of the elastic means 12. However, it is closed by the pressing force on the original crimping plate m2 by hand, the weight of the original crimping plate m2, and the inertial force, and when it reaches a predetermined closing angle, for example, 10 degrees, the moment in the closing direction of the original crimping plate m2 is increased. It starts to win and is automatically closed even if the hand is released, but in the one according to the present invention, the damper means 13 operates to perform a cushioning action, so that the original crimping plate m2 is suddenly closed and is large. There is no need to worry about making noise or pinching your hands.

受圧部材8とカムスライダー10のカム部10fとの摺動面には潤滑用のグリスが塗布されている。この摺動面には、カムスライダー10の上り傾斜部10cの側に複数のグリス溜まり10gが設けられている。グリス溜まり10gの形状と設置位置及び数については限定はない。 Lubrication grease is applied to the sliding surface between the pressure receiving member 8 and the cam portion 10f of the cam slider 10. On this sliding surface, a plurality of grease pools 10g are provided on the side of the uphill inclined portion 10c of the cam slider 10. There is no limitation on the shape, installation position and number of 10g of grease pool.

原稿が本のように厚い厚物原稿m7の場合には、この厚物原稿m7を図12に示したように、コンタクトガラスm3(原稿載置台)上へ載せて原稿圧着板m2を下押しすると、同じく図12に想像線で示したように、リフトシャフト4を支点に回転するリフト部材6の両側板6b、6bに取り付けた作動部材9によってスプリング受け部材11が押され、弾性手段12の弾力に抗してカムスライダー10側に摺動すると共に、原稿圧着板m2がリフト部材6と共にリフトシャフト4を軸に回転して、厚物原稿m7の上面を水平に覆うことになる。従って、この考案の原稿圧着板開閉装置A1は、原稿の厚さに関係なく原稿を装置本体m1の上面に安定して圧着させ、とくに厚物原稿m7の場合には、外光がコンタクトガラスm3から装置本体内の露出系に侵入するのを可及的に防止することができるものである。 When the manuscript is a thick manuscript m7 like a book, the thick manuscript m7 is placed on the contact glass m3 (manuscript mounting table) and the manuscript crimping plate m2 is pushed down as shown in FIG. Similarly, as shown by an imaginary line in FIG. 12, the spring receiving member 11 is pushed by the operating members 9 attached to the side plates 6b and 6b of the lift member 6 rotating around the lift shaft 4 as a fulcrum, and the elasticity of the elastic means 12 is increased. While sliding toward the cam slider 10 side, the document crimping plate m2 rotates around the lift shaft 4 together with the lift member 6 to horizontally cover the upper surface of the thick document m7. Therefore, the original crimping plate opening / closing device A1 of the present invention stably crimps the original to the upper surface of the apparatus main body m1 regardless of the thickness of the original, and in the case of the thick original m7, the external light is the contact glass m3. It is possible to prevent the device from invading the exposed system in the main body of the device as much as possible.

図13〜図23は、本考案に係る原稿圧着板開閉装置の実施例2を示している。この実施例2に係る原稿圧着板開閉装置A2は、実施例1に係る原稿圧着板開閉装置A1より大型のものであるが、実質的に見て同じ構成である。そのため、取付部材20、支持部材21、ヒンジシャフト22、リフトシャフト23、受圧部材24、リフト部材25、作動部材27、カムスライダー28及びスプリング受け部材29の主として幅が、実施例1のものより広くなっている。これは主としてこの実施例2に係る原稿圧着板開閉装置A2が、実施例1の原稿圧着板開閉装置A1のものに比べて、重量のある原稿圧着板m5を開閉することによるものである。 13 to 23 show Example 2 of the document crimping plate opening / closing device according to the present invention. The original crimping plate opening / closing device A2 according to the second embodiment is larger than the original crimping plate opening / closing device A1 according to the first embodiment, but has substantially the same configuration. Therefore, the widths of the mounting member 20, the support member 21, the hinge shaft 22, the lift shaft 23, the pressure receiving member 24, the lift member 25, the operating member 27, the cam slider 28, and the spring receiving member 29 are mainly wider than those of the first embodiment. It has become. This is mainly because the document crimping plate opening / closing device A2 according to the second embodiment opens / closes the document crimping plate m5, which is heavier than that of the document crimping plate opening / closing device A1 of the first embodiment.

取付部材20は、とくに図17と図21乃至図23に示したように、複合機M2の装置本体m4上に取り付けられる取付板20aと、この取付板20aの両側部からそれぞれ当該取付板20aに対して直交する上方向(略直交する方向も含む)に向けて設けられた両側板20b、20bと、取付板20aの後端部から該取付板20aに対して直交する上方に向けて設けられ、その両側部を両側板20b、20bに係止させた略矩形状の後板20cと、で構成されている。 As shown in FIGS. 17 and 21 to 23, the mounting members 20 are mounted on the mounting plate 20a mounted on the device main body m4 of the multifunction device M2, and from both sides of the mounting plate 20a to the mounting plate 20a, respectively.

In this respect, conventionally known ones are a friction washer or a spring washer in which a hinge portion is provided at one end of the hinge shaft and the hinge shaft is inserted between the side plate of the mounting member on the side where the flange portion is provided and the side plate of the support member. The friction torque was created by crimping the other end side of the hinge shaft by interposing the hinge shaft. However, according to the present invention, as will be described later, a braking means B2 for separately creating the friction torque is provided. Since the friction washer and spring washer of the hinge shaft 22 can be omitted, the manufacturing cost can be reduced.

この実施例2に係るヒンジシャフト22が、2分割されたもので構成しても良いことは、実施例1で説明した。ヒンジシャフト22の中には、この実施例2のヒンジシャフト22や実施例3のヒンジシャフト38も同じであるが、2分割したものも含まれる。 It has been described in Example 1 that the hinge shaft 22 according to the second embodiment may be formed by being divided into two parts.

As a result, it is connected to the outside of the support member 21 so as to be rotatable with respect to the support member 21. Further, mounting holes 25e and 25e are provided on the sides of the lift member 25 connected by the lift shafts 23 on both side plates 25b and 25b with a common axis, and the mounting holes 25e and 25e are pin-shaped.

The small diameter portions of the deformed holes 25d and 25d for attaching the lift shaft 23 and the deformed holes 25e and 25e for attaching the operating member 27 are opposite to each other, and the small diameter portions of the deformed holes 25d and 25d for attaching the lift shaft 23. It faces slightly downward. This is because the elasticity of the elastic means 130 acting on the operating member 27 receives pressure on the side provided with the small diameter portion. The deformed holes 25e and 25e connecting the operating member 27 have different shapes on the left and right, and the small-diameter portion of the operating member 27 is inserted and engaged with the deformed hole, and both ends are crimped. ing. In both cases, the E-ring and the like are omitted to facilitate the attachment of the lift shaft and the connecting member to reduce the cost.

It is housed and is provided between the cam slider 28 and the spring receiving member 29.

なお、作動部材27は、実施例のものは金属製のピン状のものであるが、この実施例の外に、リフト部材25に頂板を設け、この頂板を内側へ折り曲げたり、頂板に他部材から成る作動部材を取り付けることもできる。また、作動部材27はリフト部材25の両側板25b、25b間に回転可能或は固定して取り付けることができる。 The actuating member 27 is a metal pin-shaped one in the embodiment, but in addition to this embodiment, a top plate is provided on the lift member 25, and the top plate is bent inward, or another member is formed on the top plate. It is also possible to attach a working member made of. Further, the operating member 27 can be rotatably or fixedly attached between the side plates 25b and 25b of the lift member 25.

次に、ブレーキ手段B2は、支持部材21の背板21aの内壁面の後部側に所定間隔を空けてほぼ平行に設けられた一対のフリクション凸条部32、32で構成されており、原稿圧着板m4の所定開閉角度範囲において、カムスライダー28の背部28aと圧接することにより、ヒンジシャフト22を支点に回転する支持部材21に対してブレーキ作用を営むようになっている。各フリクション凸条部32、32の形状は、その始端部32a、32aと終端部32b、32bにそれぞれ中央部に向けてなだらかに高くなる傾斜部32c、32cと32d、32dが設けられ、中央部は平坦部32e、32eが形成されている。各フリクション凸条部32、32の高さは、平坦部32e、32eの部分で0.35mm程度である。各始端部32a、32aと終端部32b、32bの形状は、カムスライダー28の後端部側の縁部に対して平行、即ち支持部材21の両側板21b、21bに対して直交状態である。この始端部21a、21aと終端部32b、32bの形状は、半円形状や尖頭形状とすることもできる。その他の実施例として、フリクション凸条部32、32を1本にしてその幅を広げたり、数をさらに増やすことを排除するものではないが、実施例のものが好適である。 Next, the brake means B2 is composed of a pair of friction ridges 32, 32 provided substantially parallel to the rear side of the inner wall surface of the back plate 21a of the support member 21 at predetermined intervals, and crimps the original. By pressing the back portion 28a of the cam slider 28 in a predetermined opening / closing angle range of the plate m4, a braking action is performed on the support member 21 rotating around the hinge shaft 22 as a fulcrum. The shapes of the friction ridges 32 and 32 are such that the start ends 32a and 32a and the end portions 32b and 32b are provided with inclined portions 32c, 32c and 32d and 32d which gradually increase toward the center, respectively. The flat portions 32e and 32e are formed in the above. The height of the friction ridges 32, 32 is about 0.35 mm at the flat portions 32e, 32e. The shapes of the start end portions 32a and 32a and the end portions 32b and 32b are parallel to the edge portion on the rear end portion side of the cam slider 28, that is, orthogonal to the side plates 21b and 21b of the support member 21. The shapes of the start ends 21a and 21a and the end portions 32b and 32b may be semicircular or pointed. As another embodiment, it is not excluded that the friction ridges 32, 32 are combined into one to widen the width or further increase the number, but the one of the embodiment is preferable.

かかる実施例の場合、とくにカムスライダー28は支持部材21の背板21aの内壁側と抱持片21c、21cとの間の寸法と、支持部材21の両側板21b、21bの内側の寸法より、約0.1mm程度小さく形成されている。これはブレーキ手段B2のフリクション凸条部32、32の厚さを考慮したものである。 In the case of such an embodiment, in particular, the cam slider 28 is based on the dimensions between the inner wall side of the back plate 21a of the support member 21 and the holding pieces 21c and 21c and the inner dimensions of the side plates 21b and 21b of the support member 21. It is formed as small as about 0.1 mm. This takes into consideration the thickness of the friction protrusions 32, 32 of the braking means B2.

さらに、ブレーキ手段B2のフリクション凸条部32、32は、支持部材21の両側板21b、21bの側に設けることもできる。さらに、カムスライダー28は合成樹脂製であるので、カムスライダー28側が変形することによって、フリクショントルクの全部或は一部を創出するように構成することもできる。 Further, the friction ridges 32, 32 of the braking means B2 can be provided on the side of the side plates 21b, 21b of the support member 21. Further, since the cam slider 28 is made of synthetic resin, it can be configured to generate all or a part of the friction torque by deforming the cam slider 28 side.

なお、受圧部材24は、実施例2のものは金属製のピン状のものであり、図示してはないが、一端部側は小径部となっており、取付部材20の両側板20b、20bに設けられた大小の取付孔20e、20fに挿入した後、その両端部をかしめることによって、取付部材20の両側板20b、20bへ固定されているが、Eリングを用いて抜け止め規制しても良い。また、回転可能に両側板20b、20bへ取り付けるようにしても良い。さらに、受圧部材24はピン状でなくとも、断面凸形状を呈するように構成した板金製あるいは合成樹脂製の湾曲部材を、取付部材20の両側板20b、20bの内側へ固着するようしても良い。さらに、この受圧部材24には、合成樹脂製或は他の材料で構成した筒体を嵌めて固定したり、或は回転可能とすることは任意である。 The pressure receiving member 24 of the second embodiment is a metal pin-shaped member, and although not shown, one end side has a small diameter portion, and both side plates 20b and 20b of the mounting member 20 are formed. After being inserted into the large and small mounting holes 20e and 20f provided in the mounting member 20, both ends thereof are crimped to be fixed to both side plates 20b and 20b of the mounting member 20, but the E-ring is used to prevent the mounting member 20 from coming off. You may. Further, it may be rotatably attached to both side plates 20b and 20b. Further, even if the pressure receiving member 24 is not pin-shaped, a curved member made of sheet metal or synthetic resin configured to exhibit a convex cross section may be fixed to the inside of the side plates 20b, 20b of the mounting member 20. good. Further, it is optional that a cylinder made of synthetic resin or another material is fitted and fixed to the pressure receiving member 24, or is rotatable.

また、この実施例2に係る原稿圧着板開閉装置m5には、支持部材21のフリクションストッパー手段33が設けられている。このフリクションストッパー手段33は、とくに図17に示したように、取付部材20の両側板20b、20bの各上部に設けた制動片20d、20dと、この制動片20d、20dに原稿圧着板m5の開閉角度によって、当接するカムスライダー28の両側部に設けたところの、とくに図19に示した突起部28h、28hとで構成されている。 Further, the document crimping plate opening / closing device m5 according to the second embodiment is provided with the friction stopper means 33 of the support member 21. As shown in FIG. 17, the friction stopper means 33 includes braking pieces 20d and 20d provided on the upper portions of both side plates 20b and 20b of the mounting member 20, and document crimping plates m5 on the braking pieces 20d and 20d. It is composed of protrusions 28h and 28h shown in FIG. 19 provided on both sides of the cam slider 28 that abuts depending on the opening / closing angle.

次に、上記実施例2に係る原稿圧着板開閉装置A2の動作について説明する。今、とくに図21に示したように、想像線で示した原稿圧着板m5を閉じた状態においては、主として当該原稿圧着板m5の重量により、弾性手段30の弾力に抗して原稿圧着板m5は閉じられ、安定した閉成状態を保っている。なお、ここのところは、図示したように、受圧部材24が原稿圧着板m5の閉成時にカムスライダー28の下り傾斜28dに当接させることにより、原稿圧着板m5を閉成方向へ回転付勢させることもできる。いずれにしても、原稿圧着板m5の閉成状態において、受圧部材24はその軸方向の側部をカムスライダー28のカム部28fと当接させており、最も圧縮された状態の弾性手段30の弾力を受けている。 Next, the operation of the document crimping plate opening / closing device A2 according to the second embodiment will be described. Now, especially as shown in FIG. 21, when the original crimping plate m5 shown by the imaginary line is closed, mainly due to the weight of the original crimping plate m5, the original crimping plate m5 opposes the elasticity of the elastic means 30. Is closed and remains in a stable closed state. At this point, as shown in the drawing, the pressure receiving member 24 is brought into contact with the downward inclination 28d of the cam slider 28 when the document crimping plate m5 is closed, so that the document crimping plate m5 is rotationally urged in the closing direction. You can also let it. In any case, in the closed state of the document crimping plate m5, the pressure receiving member 24 has its axial side portion in contact with the cam portion 28f of the cam slider 28, and the elastic means 30 in the most compressed state. It is elastic.

次に、図21に示した状態から原稿圧着板m5を開くと、具体的な図示は、実施例1の図10と同じであるので、省略するが、カムスライダー28のカム部28fの受圧部材24に対する当接位置が、該カム部28fの下り傾斜部28dから上り傾斜部28c高い方に移動し、そこからから低い方へ圧接状態を維持させたまま移動することから、弾性手段30の弾力により原稿圧着板m5は、その本来の重量を減殺された状態で開かれる。開いた原稿圧着板m5より手を離すと、受圧部材24の当接位置が弾性手段30によって一方向へ摺動を付勢されているカムスライダー28の上り傾斜部28cの高い方へ移動するフリクション抵抗に遭遇することにより、原稿圧着板m5が支持部材21を介してヒンジシャフト22の周りに発生させる回転モーメントと、弾性手段30の弾力と、カムスライダー28の上り傾斜部28cに圧接している受圧部材24とによって創出される回転トルクが均衡することから、手を放しても自然に閉じてしまうことはない。実施例のものは原稿圧着板Cm5の20度以上の開成角度で、当該原稿圧着板m5を安定停止保持する。 Next, when the original crimping plate m5 is opened from the state shown in FIG. 21, the specific illustration is the same as that of FIG. 10 of the first embodiment, and thus the pressure receiving member of the cam portion 28f of the cam slider 28 is omitted. Since the contact position with respect to 24 moves from the downward inclined portion 28d of the cam portion 28f to the higher side of the upward inclined portion 28c and then to the lower side while maintaining the pressure contact state, the elasticity of the elastic means 30 The original crimping plate m5 is opened in a state where its original weight is reduced. When the hand is released from the open document crimping plate m5, the contact position of the pressure receiving member 24 moves to the higher side of the ascending inclined portion 28c of the cam slider 28 whose sliding is urged in one direction by the elastic means 30. By encountering resistance, the original crimping plate m5 is in pressure contact with the rotational moment generated around the hinge shaft 22 via the support member 21, the elasticity of the elastic means 30, and the ascending inclined portion 28c of the cam slider 28. Since the rotational torque generated by the pressure receiving member 24 is balanced, the slider does not close naturally even if the hand is released. In the embodiment, the original crimping plate m5 is stably stopped and held at an opening angle of 20 degrees or more of the original crimping plate Cm5.

原稿圧着板m5が図21に示した閉成状態から図示は省略してあるが、20度まで開かれると、摺動するカムスライダー28の後部がブレーキ手段B2のフリクション凸条部32、32に乗り下げ圧接し状態となることから、ブレーキ作用が生じる。この際に、フリクション凸条部32、32のカムスライダー28側にはなだらかな上り傾斜部32c、32cが形成されているので、カムスライダー28のフリクション凸条部32、32に対する接触はがくんとした衝撃を与えるものではなく、滑らかになされることになり、操作性の向上が図られることになる。このブレーキ作用は原稿圧着板m5の開成角度が60度に達するまで続き、60度を超えると、図21に示したように、カムスライダー28は受圧部材24から離れ、フリクションストッパー手段33が動作することになる。このフリクションストッパー手段33は、カムスライダー28の突起部28h、28hが取付部材20の両側板側に設けた制動片20d、20dに当接し始めることによって動作し、原稿圧着板m5の最大開成角度である90度まで継続して動作し、原稿圧着板m5の急激な跳ね上げと最大開成角度(実施例では90度)からの急激な落下を防止することができるものである。 Although not shown in the closed state shown in FIG. 21 when the document crimping plate m5 is opened to 20 degrees, the rear portion of the sliding cam slider 28 becomes the friction protrusions 32 and 32 of the braking means B2. A braking action is generated because the vehicle is in a state of being pressed against the vehicle. At this time, since the gentle ascending inclined portions 32c and 32c are formed on the cam slider 28 side of the friction ridges 32 and 32, the contact of the cam slider 28 with the friction ridges 32 and 32 is a rugged impact. It will be smoothed instead of giving, and the operability will be improved. This braking action continues until the opening angle of the document crimping plate m5 reaches 60 degrees, and when it exceeds 60 degrees, the cam slider 28 separates from the pressure receiving member 24 and the friction stopper means 33 operates. It will be. The friction stopper means 33 operates when the protrusions 28h and 28h of the cam slider 28 start to come into contact with the braking pieces 20d and 20d provided on both side plates of the mounting member 20, and at the maximum opening angle of the document crimping plate m5. It operates continuously up to a certain 90 degrees, and can prevent the document crimping plate m5 from suddenly flipping up and suddenly falling from the maximum opening angle (90 degrees in the embodiment).

次に、図23に示したように、90度まで開いた原稿圧着板m5を閉じる際には、フリクションストッパー手段33のフリクション抵抗に遭遇するが、このフリクション抵抗に抗して原稿圧着板m5を閉じると、閉成角度60度辺から受圧部材24が弾性手段30が作用しているカムスライダー28の上り傾斜部28cの下側に当接する。これより原稿圧着板m5をさらに閉じると、受圧部材24が上り傾斜部28cの下方から弾性手段30の弾力に抗してカムスライダー28の上り傾斜部28cの高い方へ摺働する際の抵抗に遭遇するが、手による原稿圧着板m5に対する押圧操作によって閉じられる。原稿圧着板m5が閉じられ、所定の閉成角度、例えば20度になると、原稿圧着板m5の閉成方向のモーメントが勝り始め、手を離しても自動的に閉じられるが、ダンパー手段が31が緩衝作用を行うので、原稿圧着板m5が急激に閉じられて大きな音を立てたり、手を挟んでしまう心配がない。 Next, as shown in FIG. 23, when closing the original crimping plate m5 opened to 90 degrees, the friction resistance of the friction stopper means 33 is encountered, but the original crimping plate m5 is opposed to this friction resistance. When closed, the pressure receiving member 24 comes into contact with the lower side of the ascending inclined portion 28c of the cam slider 28 on which the elastic means 30 acts from the closing angle of 60 degrees. When the document crimping plate m5 is further closed from this, the pressure receiving member 24 acts as a resistance when the pressure receiving member 24 slides from below the ascending inclined portion 28c toward the higher side of the ascending inclined portion 28c of the cam slider 28 against the elasticity of the elastic means 30. Although it is encountered, it is closed by a manual pressing operation on the original crimping plate m5. When the original crimping plate m5 is closed and reaches a predetermined closing angle, for example, 20 degrees, the moment in the closing direction of the original crimping plate m5 begins to increase and is automatically closed even if the hand is released, but the damper means is 31. Acts as a buffer, so there is no concern that the document crimping plate m5 will be closed suddenly and make a loud noise or pinch your hands.

この際、受圧部材24とカムスライダー28のカム部28fとの摺動面にグリス溜まりを設けると、なお一層グリスの保持能力が向上するものである。このグリス溜まり28k、28k・・は、実施例ではカムスライダー28のカム部28fの上り傾斜部28cと下り傾斜部28dに設けられている。このグリス溜まり28k、28kの形状と位置については限定はない。 At this time, if a grease pool is provided on the sliding surface between the pressure receiving member 24 and the cam portion 28f of the cam slider 28, the grease holding ability is further improved. The grease pools 28k, 28k ... Are provided in the ascending portion 28c and the descending inclined portion 28d of the cam portion 28f of the cam slider 28 in the embodiment. There is no limitation on the shape and position of the grease pools 28k and 28k.

なお、原稿が本のように厚い厚物原稿の場合の動作については、実施例1と同じであるので説明を省略する。 The operation when the original is a thick original such as a book is the same as that in the first embodiment, and thus the description thereof will be omitted.

このように、実施例2に係る原稿圧着板開閉装置m5にあっては、ダンパー手段31と、ブレーキ手段B2と、フリクションストッパー手段33によって、原稿圧着板m5の全開閉角度において、支持部材21の回転が制御されることによって原稿圧板m5の開閉操作がスムーズになされる。このような構成は、実施例1と後述する実施例3のものにも適用できるものである。 As described above, in the document crimping plate opening / closing device m5 according to the second embodiment, the support member 21 is provided with the damper means 31, the braking means B2, and the friction stopper means 33 at all the opening / closing angles of the document crimping plate m5. By controlling the rotation, the opening and closing operation of the document pressure plate m5 is made smooth. Such a configuration can also be applied to those of the first embodiment and the third embodiment described later.
