Abstract
In an original pressing plate hinge including a fixing member, an original pressing plate supporting member pivotably installed via a hinge pin to the fixing member, a slider slidably housed in the supporting member, a cam member fixed between the slider and the free end of the supporting member in contact with the slider, and a coil spring provided resiliently between the slider and the free end of the supporting member, the cam member is omitted to prevent an original or document set on the platen glass for copying or printing from being stained with or spoiled by a lubricant when the original touches the cam member to which the lubricant sticks, and instead a pressure receiving pin or roller is used and a cam slider is used in place of the slider. To prevent a heavy original pressing plate from abruptly falling, a damping member is housed in the coil spring and disposed between the cam slider and the top plate or free end of the supporting member.
