Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a paper tray, and more specifically, it is a paper tray that receives print paper or manuscript paper that is ejected from the printer section of electronic whiteboards, the document reading section of facsimile machines, etc. This relates to the paper tray that is stopped.

[Technical background of the invention]

Generally, this type of paper tray has a shoot board 3 that is attached obliquely at a predetermined angle to the bottom of the paper outlet 2 of a printer 1 in, for example, an electronic whiteboard, as shown in FIG. A paper receiving portion 4 is formed at the lower end of the shoot board 3 by folding the end portion upward. That is, the print paper P sent out from the paper outlet 2 falls while sliding on the shoot board 3, and its lower end is supported by the paper receiving section 4, but the conventional shoot board 3 is just a flat plate. Because of this configuration, especially when the print paper P has curls, there is a risk that the bottom edge of the paper P will curl up and the print paper P will accumulate at the bottom of the paper receiving section 4 in a curled state. In addition to this, as the number of sheets of print paper P increases, the print paper P gradually swells and eventually collapses and falls. Furthermore, when the print paper P becomes rounded, the top edge of the print paper P falls, causing the bottom edge of the next print paper P to catch on the top edge of the print paper P already on the tray, causing a paper jam in the worst case. There was a drawback of doing so.

[Purpose of invention]

This idea was devised in view of the above-mentioned drawbacks of the conventional paper, and its purpose is to ensure that even if the paper has curls, it can be received without causing any roundness. The objective is to provide a paper tray with a high quality paper tray.

〔Example〕

Hereinafter, this invention will be described in detail with reference to embodiments shown in the accompanying drawings.

As shown in FIG. 1, this paper tray 10 has a shoot board 11 that is attached at a predetermined angle to the bottom of a paper outlet 2 (see FIG. 5) of a printer, etc. A paper receiving portion 12 is formed at the bottom of the substrate 11. In this case, if the ejection direction of the print paper P ejected from the paper ejection port 2 is A, the shoot board along the ejection direction A is 11 central part 1
1a are both side parts 11b of this shoot board 11,
It is bent so as to be located on either one of the virtual planes L (see FIG. 2) including 11b. According to this embodiment, the central portion 11a of the shoot board 11
has a mountain shape that is bent toward the front side in a dogleg shape, so that even if the printing paper P is curled, the printing paper P will be curled during the ejection process. I try not to let that happen. That is, print paper P
is guided in a dogleg or C-shape along the shoot board 11, so that its lower end and upper end are particularly prevented from being rounded in a direction perpendicular to the discharge direction A. Note that, unlike this embodiment, the center portion 11a of the shoot board 11 may be bent toward the back side in a dogleg shape to form a valley shape, as shown by the imaginary line in FIG. According to this embodiment, the center portion of the print paper P is concave, contrary to the above embodiment, but the print paper P can be similarly discharged without being rounded.

Further, according to this embodiment, the width of the paper receiving section 12 is made narrower than the width of the shoot board 11, and notches 13 are formed on both sides of the lower end of the shoot board 11. . As a result, both lower ends of the print paper P discharged onto the shoot board 11 are released by the notches 13, 13, as illustrated in FIG. 3, and come to embrace the shoot board 11. Therefore, it is possible to more reliably prevent the print paper P from curling in the direction perpendicular to the discharge direction A.

Next, the paper receiving part 12 of this paper tray will be explained. As shown in FIG. However, according to this invention, the inner surface of the front wall 12a that is folded upward is provided with the shoot board 11.
The lower end of the print paper P discharged upward is connected to the rear wall 12.
A paper pressing member 14 that presses the paper toward the b side is provided. In this embodiment, the paper pressing member 14 is formed of a wedge-shaped body that is low at its lower side and has a maximum height at its upper side, and the paper pressing member 14 is arranged symmetrically across the central portion 11a of the shoot board 11. It is provided. Therefore, according to this, the lower end of the print paper P is held by this paper pressing member 1.
4, it is corrected along the chute board 11, and the end thereof is aligned in the ejection direction A as in the conventional case.
There is no such thing as curling in a direction perpendicular to .

Further, in this embodiment, a protrusion 15 is provided on the upper part of the shoot board 11 so as to cover the upper end of the print paper P discharged onto the shoot board 11. This prevents the bottom edge of paper _{P 2} from touching the top edge of print paper P ₁ that has already been ejected. In this case, in the illustrated example, three protrusions 15 are provided, and these protrusions 15 cover a part of the upper end of the print paper P ₁ that has already been discharged. _P1
Of course, it can be modified to cover the entire upper end of the .

Although the above embodiment has been described with reference to print paper discharged from a printer, this paper tray can also be applied to, for example, a document paper discharge section in a facsimile transmission section.

〔effect〕

As is clear from the above description of the embodiment, according to this invention, the center portion 11a of the shoot board 11 along the ejection direction of the print paper P is placed on either side of the virtual plane including both sides of the shoot board 11. A paper presser member 14 is provided on the back side of the front wall 12a of the paper receiver 12, and the paper presser member 14 presses the lower end of the print paper P along the shoot board 11. As a result, even if the paper P is curled, the paper P can be received in an orderly manner without causing any curling.
