Description of the Related Art Conventionally, this type of paper tray is attached to a paper discharge port of a recording device or a reading device such as a facsimile apparatus, and receives and discharges the paper discharged from the paper discharge port on a mounting surface. is there. On the mounting surface of such a paper tray, a rib for supporting the lower surface of the discharged paper is formed so as to protrude in the paper discharging direction, and therefore, the contact area between the paper and the mounting surface is reduced. It is configured so that the paper becomes smaller and the paper discharge proceeds smoothly.

[0003]

However, in the above-mentioned conventional paper tray, when a plurality of sheets are discharged onto the mounting surface, the second and subsequent sheets come into contact with the ribs on the mounting surface. Since there is no problem, the following paper pushes out the preceding paper due to friction between the papers, so that there is a problem that the paper is discharged while being skewed and not discharged in a state where it is perfectly aligned.

[0004] The present invention has been proposed in view of the above points, and has as its object to provide a paper tray capable of discharging sheets in an orderly arrangement without skewing the sheets.

[0005]

In order to achieve the above object, a paper tray according to the present invention is attached to a paper discharge port of a recording device or a reading device, and a sheet discharged from the paper discharge port. A sheet tray having a plurality of rows of ribs protrudingly formed along the sheet discharge direction on the placement surface, while receiving and placing the sheet tray on the placement surface. In a state that sandwiches
The ribs are arranged in pairs in two rows, and the ribs in the pair in two rows are formed so as to sequentially increase inward from the inside to the outside for each pair corresponding to each width dimension of the paper. It is characterized by the following.

According to such a sheet tray, even when a plurality of sheets are discharged onto the mounting surface, the plurality of overlapping sheets are formed by a pair of ribs having two side edges in the width direction. Since the paper is sandwiched, the paper discharge direction is regulated and the paper does not skew. Therefore, the paper can be discharged in a state in which the papers are aligned in the discharge direction. In addition, the pair of ribs in two rows are formed so that the height of the pair of ribs is gradually increased from the inside to the outside corresponding to each width dimension of the sheet. Since sheets having different widths are sequentially sorted and arranged from below in order, a single sheet tray can be used for sheets of different widths. In addition, a special rib shape is not required, and a simple rib shape can reduce the manufacturing cost.

The paper may be a row A or a row B of recording paper or a read original, but is not limited thereto, and may be a postcard or a letter size, or may be a resin film.

According to a second aspect of the present invention, there is provided the paper tray according to the first aspect, wherein the pair of ribs in the two rows project with the length of each longitudinal dimension of the paper. Is formed.

According to such a paper tray, claim 1
In addition to the effect of the paper tray described in 2, the pair of ribs in two rows is formed with the length of each longitudinal dimension of the paper, so that even if the subsequent paper pushes out the preceding paper, it is pushed out. Since a part of both side edges of the sheet is kept sandwiched by the ribs, the discharging direction of the sheet is restricted, and skew is prevented.

Further, the paper tray according to the third aspect of the present invention is the paper tray according to the first or second aspect, wherein the two rows and the pair of ribs are close to the paper discharge port. The sheet is formed so as to protrude from a position along the sheet discharge direction.

According to such a paper tray, claim 1
Alternatively, in addition to the effect of the paper tray according to claim 2, the pair of ribs in two rows is formed from a position close to the paper discharge port, so that the discharge direction of the paper immediately after discharge is restricted by the rib. Therefore, skewing of the sheet can be reliably prevented.
