ABSTRACT:
An original pressing device for use in a reading apparatus. There is a hinge together with a pressing unit supported pivotably by the hinge and pivoting between a closing position where an original on a platen is pressed and an opening position where the original is released. A coil spring is compressed with the closing operation of the pressing unit and is released from the compression along with the opening operation of the pressing unit, and a fluid damper is arranged within a hollow portion of the coil spring to provide a resistance force when the pressing unit performs the closing operation.
