Description
指示記号13で示したものは、リフト部材であり、このリフト部材13は、図2から図12に示したように、上板13aと、この上板13aの両側部より下方へ垂下させた両側板13b、13bと、この両側板13b、13bの下端部より外側へ折り曲げたところの原稿圧着板3の取付板13c、13cとで構成されている。このリフト部材13は、その両側板13b、13bを支持部材8の両側板8b、8bの自由端側へ第2ヒンジピン10を介して支持部材8とは逆方向へ回転可能に取り付けられている。このリフト部材13の上板13aと取付板13c、13cには原稿圧着板3の後部が取り付けられている。尚、支持部材8とリフト部材13の各両側板8b、8b・13b、13bの第2ヒンジピン10を軸受けする部分には軸受部材を設けることが好ましい。 What is indicated by an instruction symbol 13 is a lift member. As shown in FIGS. 2 to 12, the lift member 13 has an upper plate 13a and both sides suspended downward from both sides of the upper plate 13a. It consists of plates 13b and 13b and mounting plates 13c and 13c of the original cover 3 that are bent outward from the lower ends of the side plates 13b and 13b. The lift member 13 is attached to both side plates 13b, 13b of the support member 8 on the free end side of the side plates 8b, 8b via the second hinge pin 10 so as to be rotatable in the opposite direction to the support member 8. Upper plate 13a and the mounting plate 13c of the lifting member 13, the rear portion of the original cover 3 that is attached to 13c. In addition, it is preferable to provide a bearing member in the part which bears the 2nd hinge pin 10 of each side plate 8b, 8b * 13b, 13b of the supporting member 8 and the lift member 13. As shown in FIG.
原稿圧着板3の自立開成角度は、略30°〜60°の間であるのが通常である。この開成角度が60度を超えてくると、第1バネ受部材11の摺動が阻止される結果、カム部11bと受圧部材16との間が離れ始め、原稿圧着板3を手で押し上げることにより、図11に示したように、最大開成角度の90度まで開かれることになる。原稿圧着板3は、この90度の最大開成角度において、支持部材8の後端部が取付部材4の後端部に当接することにより、停止させられる。90度開いた原稿圧着板3を閉じる際には、60度まで閉じられると第1バネ受部材11のカム部11bが受圧部材16に当接するので、圧縮コイルスプリング14の弾力がきき始め、原稿圧着板3は手で下押しすることによって圧縮コイルスプリング14の弾力に抗して閉じられ、30度の閉成角度から原稿圧着板3が第1ヒンジピン9の周りに発生させる回転トルクが圧縮コイルスプリング14の弾力に勝ることから、原稿圧着板3は手を放しても自重で静かに閉じられることになる。 Usually, the self-standing opening angle of the original cover 3 is between approximately 30 ° and 60 °. When the opening angle exceeds 60 degrees, the sliding of the first spring receiving member 11 is prevented, and as a result, the cam portion 11b and the pressure receiving member 16 begin to separate, and the original cover 3 is pushed up by hand. Thus, as shown in FIG. 11, the maximum opening angle is 90 degrees. The original cover 3 is stopped when the rear end portion of the support member 8 contacts the rear end portion of the attachment member 4 at the maximum opening angle of 90 degrees. When closing the original cover 3 opened 90 degrees, the cam portion 11b of the first spring receiving member 11 comes into contact with the pressure receiving member 16 when the original pressing plate 3 is closed to 60 degrees. The crimping plate 3 is closed against the elasticity of the compression coil spring 14 by being pushed down by hand, and the rotational torque generated by the document crimping plate 3 around the first hinge pin 9 from the closing angle of 30 degrees is caused by the compression coil spring. Since the elasticity of 14 is surpassed, the original cover 3 is closed quietly by its own weight even if it is released.
さらに、本発明において、以上に実施例においては、作動部材17や26の一端部には係止部17aやフランジ部26aが設けられ、この係止部17aやフランジ26a部がリフト部材13と25の両側板13b、13bや25b、25b設けた変形取付孔13e、13eや25d、25dの各一方へ係止されているが、他端部側は単に他方の変形取付孔13eや25dへ挿入した状態のものが示されている。これは作動部材17や26が常に圧縮コイルスプリング14の弾力により、各変形取付孔13e、13eや25d、25dの一方へ押圧されていることから、使用中に自然に変形取付孔13e、13eや25d、25dの一方から脱落してしまうことはないことによるが、念のため、作動部材17や26の他端部をかしめや溶着、或はEリングによって変形取付孔13e、13eや25d、25dの一方へ固定させ、軸方向へ抜け出てしまうのを防止するように構成することは任意である。 Further, in the present invention, in the above-described embodiments, the locking members 17a and the flanges 26a are provided at one end portions of the actuating members 17 and 26, and the locking members 17a and the flanges 26a are the lift members 13 and 25. The two side plates 13b, 13b, 25b, 25b are locked to one of the deformation mounting holes 13e, 13e, 25d, 25d, but the other end is simply inserted into the other deformation mounting holes 13e, 25d. The state is shown. This is because the operating members 17 and 26 are always pressed against one of the deformation mounting holes 13e, 13e, 25d, and 25d by the elasticity of the compression coil spring 14, so that the deformation mounting holes 13e, 13e, and Although it does not fall off from one of 25d and 25d, as a precaution, the deformable mounting holes 13e, 13e, 25d, and 25d are formed by caulking, welding, or E-ringing the other end of the operating members 17 and 26 It is arbitrary to fix to one of the two and prevent it from slipping out in the axial direction.
