良好にした排紙台の改良に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper discharge tray for stopping the progress of a printed printing paper sent from a paper discharge port of a printing device by means of an abutting member and dropping it onto a substrate for stacking. In particular, the present invention relates to an improvement of a paper ejection tray that eliminates unpleasant paper ejection noise generated when a printing paper collides with an abutting member, and reduces the bounce of the printing paper and its variation to improve the paper ejection alignment.

ものであり、これによれば印刷用紙５３の衝突音は多少
緩和されるが、跳ね返りは却って大きくなる傾向にあ
り、紙揃いが悪くなった。In the type in which the abutting plate 51 is integrally fixed to the substrate 52 as shown in FIG. 5, when the printing paper 53 that is vigorously sent from the printing device collides with the abutting plate 51. In addition, a large collision noise is generated to deteriorate the working environment, and the bounce of the printing paper 53 and its variation are large, and the paper alignment is poor. In FIG. 6, a foaming elastic member 54 such as a sponge is attached to the abutting plate 51 of FIG. 5. According to this, the collision sound of the printing paper 53 is somewhat mitigated, but the rebound tends to be large. And the paper alignment got worse.

ルした状態で積載されることになる。In FIG. 7, a foamable elastic member 5 such as a sponge is used.
The lower end portion of the abutting plate 51 to which 4 is attached is provided with a hinge 55 or the like to support the substrate 52 so as to vibrate (displace) by giving an elastic return force. As a result, the momentum of the printing paper 53 is absorbed by the displacement of the abutting plate 51 to reduce the rebound, but in the case of the printing paper 53 having a weak stiffness,
When the printing paper drops toward the substrate due to the extremely small bounce, the tip portion of the printing paper is not caught by the frictional resistance with the foaming elastic member 54 and does not slip down into the smooths.
It will be loaded in the assembled state.

来持っている衝突に対する消音効果が薄れてしまう。Therefore, by sticking a sheet having a smooth surface to the expandable elastic member 54 or by smoothly processing and molding the surface of the expandable elastic member 54, the catch of the printing paper 53 is improved for the time being. The muffling effect of the foamable elastic member 54 on the collision, which is originally possessed, is diminished.

数を多くできない、等々の問題があった。In response to the above problems, it was confirmed that by replacing the foaming elastic member 54 in FIG. 7 with a vibration damping member, it is possible to improve paper ejection noise and paper ejection alignment as compared with the conventional paper ejection tray. . However, in the conventional paper ejection tray that supports the lower end of the abutting plate 51, it is necessary to make the abutting plate 51 thick and to provide the reinforcing ribs to make the abutting plate 51 robust, so that the cost is high. Become. Since the supporting structure becomes complicated due to the adoption of the hinge 55 or a similar mechanism, the vibration amplitude of the abutment plate 51 increases as it goes upward, and therefore the higher the stacking position of the printing paper 53, the more the influence of the vibration of the abutment plate 51. There was a problem in that the sheets were strongly received and the alignment of discharged sheets in the vertical direction deteriorates, and the number of sheets to be stacked cannot be increased in order to keep the discharged sheet alignment within a certain range.

There was a problem that the paper ejection noise and the paper ejection alignment became poor. The damping member means a member having a repulsion elasticity of 40% or less measured according to JIS-6301.
