Abstract

PURPOSE:To smoothly open an original pressing plate by providing a ventilation gap part communicating with the outside between nearly the central surface of a wall lining sheet material layer on this side among wall lining sheet material layers composed of the original pressing plate and the upper part of an original platen. CONSTITUTION:Through holes 26 of about 0.5-3mm are provided on this side of nearly the central surface of the wall lining sheet material layer 23 composed of the original pressing plate 2. Said plate 2 is pulled down toward the upper surface of the original platen 1 to be closed. In state where the wall lining sheet material layer 23 is in hermetically contact with the upper surface of the original platen 1, the through holes 26 in the wall lining sheet material layer 23 communicate with the outside through the continuous sponge wall of a sponge cushion material layer 22, and comprise the ventilation gap part. When the original pressing plate 2 is pulled up and opened, an outside air A flows into the through holes 26 through the sponge wall of the sponge cushion material 22, further flows in smoothly to the upper surface of the original platen and the wall lining sheet material layer; therefore difficulty to open the original pressing plate 2, which is caused by air pressing phenomenon, is reduced.
