Meanwhile, since large sheets of paper also have different sizes, the second support 20 needs to be set to different heights, the larger the paper, the closer the supporting portion supporting the paper is to the outer periphery of the waste bin 50, and the higher the second support 20 is. Since the waste of the material and the waste of the space in the printer cannot be caused, when the second support 20 is installed, the height of the second support 20 needs to be reduced as much as possible when the requirement that paper is not scratched is satisfied, so that the second support 20 needs to be arranged in a slope structure in which the height of the portion close to the first support 10 is low and the height of the portion far from the first support 10 is high. The purposes of preventing paper from being scratched and reducing material space waste are achieved.
Referring to fig. 1, the first supporting member 10 is a first supporting rib 11, and the first supporting rib 11 is provided in the middle of the lower side axial direction of the waste bin 50 and can individually support paper.

For larger paper, the warping degree of the paper is large, and if the supporting piece with the same height as the small paper is arranged, the paper can touch the bottom of the waste powder bin 50, so that the second supporting piece 20 with a higher height needs to be arranged. Meanwhile, since large sheets of paper also have different sizes, the second support 20 needs to be set to different heights, the larger the paper, the closer the supporting portion supporting the paper is to the outer periphery of the waste bin 50, and the higher the second support 20 is.
Since the waste of the material and the waste of the space in the printer cannot be caused, when the second supporting member 20 is required to be installed, the height of the second supporting member 20 is reduced as much as possible when the requirement that paper is not scratched is met, and therefore, the second supporting rib 21 needs to be provided with an inclined surface structure with low height and high height of the third supporting rib 22. The purposes of preventing paper from being scratched and reducing material space waste are achieved.
Example 3
