The above-described object can be achieved by discharging printing paper having a printing area close to a non-printing state. However, in a printing state having a large printing area, the printing paper in the discharging process as shown in FIGS. After reaching the wall board, the U-shaped curve disappears or curves in the opposite direction due to the physical properties of the printing paper during the process of dropping onto the paper discharge table, causing poor paper discharge alignment. In particular, when discharging printing paper in a printing state having an extremely large printing area, such as solid printing, after passing through an upwardly sloping paper sliding surface provided on an inner side surface of a side plate erected on a discharge base plate. , The leading edge of the printing paper hangs down before it reaches the front wall, causing not only misalignment but also printing in which the leading edge of the printing paper is already placed on the paper output tray. The printed image will advance by rubbing against the upper surface of the sheet, that is, the printed image surface, which will stain the printed image of the already discharged printing sheet.

紙整合不良及び印刷画像を汚損することがない。According to the above construction, when printed printing paper reaches the discharge tray, the printed paper is guided by the upwardly inclined guide surface on the upper front surface of the side plate erected on the bottom plate of the discharge tray. The front side edges are lifted upward, and the printing paper is given a U-shaped curve when viewed in a cross section perpendicular to the paper discharging direction. Since the distance in the width direction of the passing portion of the subsequent printing paper is regulated to be shorter than the width of the printing paper by the inwardly protruding portion on the upper side of the side plate, the front edge portion of the printing paper has a front wall plate. The U-shape is maintained until the pressure reaches. The U-shape will be held halfway while falling on the paper output table,
For these reasons, it is possible to prevent the leading edge and both edges of the printing paper from sagging downward, so that even if the printing paper has an extremely large printing area, the paper can be regularly discharged, and the discharge paper alignment failure and the print image Will not be stained.

As shown in FIG. 7 and FIG.
0, the paper sliding surface 70 as shown in FIG.
You start to slide on a. As a result, the front edge portions of the printing paper are warped upward, and the discharge tray bottom plate 62 is held in a state where the U-shaped shape is held by the paper sliding surface 70b.
You will be moving up. When the leading edge of the printing paper reaches the front wall 66 as shown in the figure, the falling of the printing paper due to its own weight proceeds while maintaining the U-shape, and as shown in the figure, both edges thereof The U-shaped curve is released by dropping over the sheet sliding surface 70b, and the sheet is placed on the sheet discharge tray bottom plate 62 in a flat state as shown in the figure.

的を確実に達成することとなる。According to the present invention, before the leading edge of the printing paper reaches the front wall, the leading edge or both edges of the printing paper do not hang down due to the curl of the paper generated during printing. Thus, the flying state of the printing paper is maintained. For this reason, the leading edge of the printing paper does not advance while rubbing the upper surface of the printing paper already discharged onto the paper discharge base bottom plate, that is, the printing image surface, so that the printing image surface can be reliably prevented from being stained.
In addition, in the process of falling toward the paper output tray bottom plate, the printing paper falls without curling downward as viewed in a cross section perpendicular to the paper discharge direction in the middle of the printing paper, so that the paper discharge misalignment is also ensured. Can be avoided. From the above, the above object is surely achieved by the present invention.
