次に、支持部材７は、実施の形態のものは、取付ケース５と同じく、機械的強度に富むＰＯＭやＡＢＳなどの樹脂成型品で、取付ケース５に設けた両側板５ｄ、５ｄの間に挿入される連結部７ａと、この連結部７ａの前部側に一体に形成された左右方向に長い矩形状を呈した支持板部７ｂとを有し、この支持板部７ｂと連結部７ａの下方部分にスライダー９のカム部９ｂと接する旋回カム部７ｃが設けられている。支持部材７はまた、連結部７ａに設けた連結孔７ｄに取付ケース５とスライダー収容部材６の各両側板５ｄ、５ｄ・６ｂ、６ｂの連結孔５ｃ、５ｃと６ｆ、６ｆを介して挿入させたヒンジシャフト８により回転可能に連結されている。尚、ヒンジシャフト８は、図５に示したように、一端部側にフランジ部８ａを有する丸棒状のもので、他端部側は不図示であるが、カシメられている。しかしながら、ヒンジシャフト８の他端部に周溝を設け、Ｅリングで止めるようにしても良い。 Next, the support member 7 is, like the mounting case 5, a resin molded product such as POM or ABS having high mechanical strength, and is provided between both side plates 5d provided on the mounting case 5, 5d. It has a connecting portion 7a to be inserted, and a supporting plate portion 7b having a rectangular shape elongated in the left-right direction and integrally formed on the front side of the connecting portion 7a. A swivel cam portion 7c that contacts the cam portion 9b of the slider 9 is provided in the lower portion. The support member 7 is also inserted into a connecting hole 7d provided in the connecting portion 7a through the connecting holes 5c, 5c and 6f, 6f of the side plates 5d, 5d, 6b, 6b of the mounting case 5 and the slider accommodating member 6. rotatably connected by a hinge shaft 8. As shown in FIG. 5, the hinge shaft 8 is in the shape of a round bar having a flange portion 8a at one end, and the other end is crimped (not shown). However, the other end of the hinge shaft 8 may be provided with a circumferential groove and stopped with an E-ring.

スライダー９は、例えば樹脂成型品の角筒状を呈したものであり、内部に下部側解放のスプリング収容部９ａが設けられ、上面部にはカム部９ｂが設けられている。そして、スライダー収容部材６内に上下方向へスライド可能に収容されており、スライダー９の両側部９ｃ、９ｃと、スライダー収容部材６のフリクション凸状部６ｅ、６ｅとでスライドフリクション機構１３を構成している。 The slider 9 is, for example, in the shape of a rectangular tube made of a resin molding product, and is provided with a spring accommodation portion 9a that is open on the lower side and a cam portion 9b on the upper surface. Both side portions 9c, 9c of the slider 9 and the friction projections 6e, 6e of the slider housing member 6 constitute a slide friction mechanism 13. ing.

次に、スライダー収容部材６の底板部６ａと、スライダー９のスプリング収容部９ａの内頂部９ｄとの間には、圧縮コイルスプリングから成る弾性部材１０が弾設されており、スライダー９を図中上方向へ押し、旋回カム部７ｃを介して支持部材７を時計回りに回転付勢させている。さらに、弾性部材１０内部に収容されて流体ダンパー１１が設置されており、この流体ダンパー１１のピストン１１ａと対向して受座部材１２がスライダー収容部材６の底板部６ａ上に設置されている。受座部材１２は、内部入口側に傾斜部１２ｂを設けた受筒部１２ａが設けられており、差し込みヒンジ４の動作時にピストン１１ａが多少傾いていても受筒部１２ａにガイドされて正しい姿勢を保つことができるように工夫されている。弾性部材１０の態様或は数は、実施例のものは１本であるが、差し込みヒンジ４に求められるトルクによって様々であり、２本、３本の場合もあれば、径の異なる圧縮コイルスプリングを重ね合わせて用いる場合もある。 Between the bottom plate portion 6a of the slider accommodating member 6 and the inner top portion 9d of the spring accommodating portion 9a of the slider 9, an elastic member 10 made of a compression coil spring is elastically provided. By pushing upward, the support member 7 is urged to rotate clockwise via the turning cam portion 7c. Further, a fluid damper 11 is installed inside the elastic member 10 , and a receiving member 12 is installed on the bottom plate portion 6 a of the slider housing member 6 so as to face the piston 11 a of the fluid damper 11 . The seat member 12 is provided with a receiving cylinder portion 12a having an inclined portion 12b on the inner inlet side. It is devised to be able to keep The form or number of the elastic members 10 is one in the embodiment, but varies depending on the torque required for the plug-in hinge 4. In some cases, there are two or three, or there are compression coil springs with different diameters. are sometimes used in combination.

従って、図１０と図１３（ａ）に示したように、原稿圧着板３を閉じた状態においては、当該原稿圧着板３は、原稿載置台２ｂの上面を覆い、支持部材７の旋回カム部７ｃは、スライダー９のカム部９ｂを下方へ押圧し、弾性部材１０は、最大限圧縮された状態にあるが、原稿圧着板３がその重みでヒンジシャフト８の回りに発生させる回転トルクより、原稿圧着板３の重量の方が勝っているので、当該原稿圧着板３は弾性部材１０の弾力に抗して閉成状態を保っている。また、流体ダンパー１１のピストン１１ａの先端は受座部材１２の受筒部１２ａの内底部１２ｃに当接している。 Therefore, as shown in FIGS. 10 and 13(a), when the document pressure plate 3 is closed, the document pressure plate 3 covers the upper surface of the document table 2b, and the turning cam portion of the support member 7 rotates. 7c presses the cam portion 9b of the slider 9 downward, and the elastic member 10 is in the maximum compressed state. Since the weight of the document pressing plate 3 is greater than that of the document pressing plate 3, the document pressing plate 3 maintains the closed state against the elastic force of the elastic member 10.例文帳に追加Further, the tip of the piston 11a of the fluid damper 11 is in contact with the inner bottom portion 12c of the receiving tube portion 12a of the receiving member 12. As shown in FIG.

そこで操作者が、複写を行うべく原稿を原稿載置台２ｂ上へセットするために、原稿圧着板３を閉じた状態から開くと、図１０と図１３（ａ）に示したように、最初はスライダー９の両側部９ｃ、９ｃがスライダー収容部材６の両側板６ｂ、６ｂに設けたフリクション凸状部６ｅ、６ｅに接触していないので、操作者は原稿圧着板３をスライダー９を上方へスライド付勢させている圧縮コイルスプリングから成る弾性部材１０に弾力により、比較的軽く開くことができる。 Therefore, when the operator opens the document pressing plate 3 from the closed state in order to set the document on the document placing table 2b for copying, as shown in FIGS. 10 and 13A, at first Since the side portions 9c, 9c of the slider 9 are not in contact with the friction convex portions 6e, 6e provided on the side plates 6b, 6b of the slider housing member 6, the operator slides the document pressing plate 3 upward along the slider 9. It can be opened relatively lightly due to the elastic force of the elastic member 10, which is a compression coil spring.

原稿圧着板３をさらに開くと、図１１と図１３（ｂ）に示したように、３０度の開成角度から、スライダー９の両側部９ｃ、９ｃとスライダー収容部材６のフリクション凸状部６ｅ、６ｅから成るスライドフリクション機構１３が動作し始めるので、スライダー９の両側部９ｃ、９ｃとスライダー収容部材６のフリクション凸状部６ｅ、６ｅとの圧接に伴い、フリクション抵抗に遭遇するが、むしろこのフリクション抵抗により、しっくりとした操作感覚を覚えながら開くことができ、操作性の向上が図られる上に、原稿圧着板３が所定の開成角度から、支持部材７の旋回カム部７ｃに圧接しているスライダー９が弾性部材１０によって押されて旋回カム部７ｃを介して支持部材７を押し上げるのを防止できるので、原稿圧着板３が急激に開くことを防止できることになり、ここでも操作性の向上を図ることができるものである。また、開いた原稿圧着板３は。図１２に示したように、支持部材７の後端部７ｅが取付ケース５のストッパー凹部５ｅに当接することで停止し、それ以上開かれない。 When the document pressing plate 3 is further opened, as shown in FIGS. 11 and 13(b), both side portions 9c, 9c of the slider 9 and the friction convex portion 6e of the slider accommodating member 6 are exposed from the opening angle of 30 degrees. Since the slide friction mechanism 13 consisting of 6e begins to operate, frictional resistance is encountered as the side portions 9c, 9c of the slider 9 and the friction convex portions 6e, 6e of the slider housing member 6 are pressed against each other. Due to the resistance, it is possible to open while feeling a comfortable operation feeling, which improves the operability. Since it is possible to prevent the slider 9 from being pushed by the elastic member 10 and pushing up the support member 7 via the swivel cam portion 7c, it is possible to prevent the document pressing plate 3 from suddenly opening, thereby improving the operability. It is something that can be planned. Also, the opened document pressing plate 3 is As shown in FIG. 12, the rear end portion 7e of the support member 7 comes into contact with the stopper recessed portion 5e of the mounting case 5 and stops, and is not opened any further.

図１２と図１３（ｃ）に示した原稿圧着板３の全開状態から、原稿圧着板３を閉じる際には、スライドフリクション機構１３が動作しているので、しっくりとした操作感覚を覚えながら閉じることができ、所定閉成角度からは、スライドフリクション機構１３が動作しなくなるが、今度は、流体ダンパー１１のピストン１１ａの先端部が受座部材１２の受筒部１２ａの内底部１２ｃに当接することにより、ブレーキ作用がなされ、原稿圧着板３が急激に応閉じられるのを防止できるものである。また、この際に図示は省略してあるが、流体ダンパー１１の動作時には、スライダー９の両側部９ｃ、９ｃとスライダー収容部材６のフリクション凸状部６ｅ、６ｅは非接触状態であるので、スライドフリクション機構１３は動作せず、スムーズな緩衝作用がなされるものである。 When the document pressure plate 3 is closed from the fully open state shown in FIGS. 12 and 13C, the slide friction mechanism 13 is operating, so the user can feel a smooth operation when closing the document pressure plate 3. The slide friction mechanism 13 does not operate from the predetermined closed angle, but the tip of the piston 11a of the fluid damper 11 contacts the inner bottom 12c of the receiving tube 12a of the seat member 12. As a result, a braking action is performed to prevent the document pressing plate 3 from being suddenly closed. Also, although not shown in the drawings at this time, when the fluid damper 11 operates, the side portions 9c, 9c of the slider 9 and the friction convex portions 6e, 6e of the slider housing member 6 are in a non-contact state. The friction mechanism 13 does not operate, and a smooth cushioning action is performed.

尚、本発明に係る差し込みヒンジ４は、スライドフリクション機構１３が動作する角度範囲は３０度から最大開成角度の間であるが、この角度に限定はない。 In addition, in the plug-in hinge 4 according to the present invention, the angle range in which the slide friction mechanism 13 operates is between 30 degrees and the maximum open angle, but there is no limitation to this angle.

以上、本発明は上記の如く構成したので、複写機に代表される事務機器の中でも比較的に小型のものに用いる原稿圧着板の開閉用の差し込みヒンジとして好適に用いられるものであり、小型かつ構成が簡単で操作性の良い差し込みヒンジを提供できたものである。また、かかる差し込みヒンジを用いた事務機器としても好適に用いられるものである。 Since the present invention is constructed as described above, it can be suitably used as an insertion hinge for opening and closing the document pressing plate used in relatively small office equipment such as copiers. A plug-in hinge having a simple structure and good operability can be provided. Moreover, it can be suitably used as office equipment using such an insertion hinge.
