低下するといった問題があった。また、紙受け部材を進
入させる際に、この紙受け部材の先端が紙の側面に当り
易く、当ると紙を巻き上げるため損紙となるといった問
題もあった。However, in the above-described conventional sheet ejection device of the sheet-fed printing press, since the sheet receiving member is structured to enter substantially horizontally with respect to the paper drop path, the sheet ejection member is ejected. Depending on the speed and the discharge state, the paper may drop in a wave-like manner in the paper width direction, so that all the paper receiving members arranged in the paper width direction may enter below the falling paper. If you can't do this, you may get across two or more sheets of paper. In this case, not all of the paper receiving members can support the lower side of the paper as a whole, and the edge of the paper hangs downward from the paper receiving member.
For this reason, the paper loaded on the paper receiving member collapses, and complicated work is required to correct the collapse of the cargo, resulting in a decrease in productivity. Further, when the paper receiving member is inserted, the front end of the paper receiving member easily hits the side surface of the paper, and if it hits, the paper is rolled up, resulting in a waste paper.
