DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document stacker used in a facsimile transceiver.

[0002]

2. Description of the Related Art Conventionally, the shape of this type of original stacker is as follows.
When the original is bent downward, the original is likely to drop. Therefore, it is necessary to prevent the original from bending downward, and a shape as shown in FIG. 3 is generally used. In this shape, the original 8 is deformed as shown in FIG. 5A by providing the recess 13 at the center portion, and the bending of the leading end of the original as shown in FIG. 5B is prevented. However, in this shape, it is necessary to make the width dimension of the stacker equal to the document width up to the vicinity of the leading edge in order to prevent the corner of the leading edge of the document as shown in FIG.

[0003]

FIG. 4 is a diagram showing a general facsimile transceiver, and the arrow C indicates the direction of a person who performs an operation. In a facsimile transceiver,
It is common that a plurality of stackers 14 and 15 are vertically arranged as shown in the above. However, this conventional stacker has a drawback that the paper on the lower stacker 15 is difficult to take out. Therefore, in order to eliminate this defect, when the corner 14a of the upper stacker is largely cut off, a new defect occurs in that the leading end of the paper on the upper stacker 14 sags.

[0004]

An original stacker according to the present invention has first to third flat portions, and a first joint portion where the first and second flat portions are joined is stacked. A second joint, which is substantially parallel to and near the diagonal of the rectangular document, and where the second and third flat portions are joined, is substantially parallel to the diagonal and the first joint. At a position farther from the original loading end,
And the third flat portion is parallel to each other and substantially horizontal to the horizontal plane, the second flat portion is provided to be inclined with respect to the horizontal plane, and the first and second flat portions are A notch is formed by cutting a portion corresponding to a corner of the leading end when a document is loaded in a direction substantially orthogonal to the diagonal line, and the first flat portion is provided with It has a rib hanging vertically toward the notch,
In addition, on the first flat portion, in addition to the rib, the first stacking end portion of the original stacking end portion is positioned on the first flat portion from the side opposite to the rib.
May have at least one second rib extending vertically toward the joint.

[0005]

Next, the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of a document stacker according to the present invention, wherein FIG. 1 (a) is a perspective view, and FIG. 1 (b) is a side view of FIG. 2A and 2B show the shape of the paper on the original stacker of the present embodiment, wherein FIG. 2A is a plan view, and FIGS.

The original stacker of this embodiment has a flat portion (A)
A diagonal line of an original to be stacked by three flat portions of a flat portion (B) 2 and a flat portion (C) 3 and ribs (A) 4 and rib (B) 5 provided on the flat portion (A) 1 This has the effect of giving a stiffness in the direction, and it is possible to provide a large cutout at the corner of the tip of the stacker. The document stacker has a size to load a document of A3 size at the maximum.

As shown in FIG. 1A, a flat portion (A) 1
The flat portion (B) 2 is not parallel to each other, and the flat portion (B) 2 is provided to be inclined with respect to the flat portion (A) 1 which is substantially horizontal to the horizontal plane, and is joined to each other at the joining portion 6. . The joining portion 6 is substantially parallel to a diagonal line (represented by reference numeral 9 in FIG. 2) of a square document stacked in the direction of arrow A from the end face 1b side of the flat portion (A) 1 and is near the position of the diagonal line. Shall be provided. The flat part (C) 3 is parallel and substantially horizontal to the flat part (A) 1, and the flat part (C) 3 and the flat part (B) 2 are joined at a joint 7, and the joint 7 is joined It is provided in a part parallel to the part 6 and away from the end face 1b. That is, as shown in FIG. 1B, the original stacker has a shape in which two U-shaped ones viewed from the side are combined.

Further, in the flat portions (A) 1 and (B) 2, large notches 1 a and 2 a are orthogonal to the joints 6 and 7 at positions corresponding to the leading edge of the original to be stacked. It is provided in the form. Further, a rib (A) 4 and a rib (B) 5 which stand upright are provided on the flat portion (A) 1.
The rib (A) 4 is provided from the end face 1b to the notch 1a, and its position and dimensions are shown in FIG.
When the paper is bent as shown in (c), it is determined to be almost in contact with the back surface of the paper. On the other hand, the rib (B) 5 is located at a position opposite to the rib (A) 4 on the flat portion (A) 1.
b is provided toward the joining portion 6, and its position and dimensions are as follows:
On the stacker, the rear end of the paper is determined by the rib (A) 4 so that only one side of the rear end of the paper does not jump up as indicated by reference numeral 11 in FIG. .

Next, the shape of the paper in the original stacker of this embodiment will be described. Maximum size is A3
The paper 8, which is the size, is discharged from the direction indicated by the arrow A in FIG. 1A by an unillustrated discharge mechanism and is stacked on the stacker. Even if the rib (B) 5 and the flat part (C) 3 are not provided on the stacker, the paper 8 is formed by the rib (A) 4 and the flat part (B) 2 according to the diagonal line 9 as shown in FIG. There is no waist and the tip does not sag. However, in this case, the corners of the paper 8
0 and 11 are generated, but the rib (B) 5 and the flat portion (C)
By providing 3, the rise of the corner is suppressed, and together with the rib (A) 4, the stiffness in the diagonal line 9 direction is strengthened, and the paper 8 has a substantially flat shape as shown in FIG. Therefore, the notch 12 shown in FIG. 1A and FIG.
Is large, the paper 8 does not bend downward from the cutout portion 12 and the paper 8 does not fall from the stacker.

The above-mentioned ribs (A) 4 and ribs (B)
5 on the flat portion (A) 1 is such that even if a document of the minimum size (for example, B5 size) is loaded on the stacker, the document is placed on the ribs (A) 4 and the ribs (B). 5 without falling, and the above-mentioned diagonal 9
Shall be provided at a position sufficient to cause the waist action.

[0012]

As described above, according to the present invention, a diagonal waist is formed in the paper by two flat portions and one rib which are not parallel to each other, thereby obtaining a stacker having a large cutout at the corner. . The rise of the corners of the leading and trailing edges of the document is suppressed by adding another flat portion and a rib, and the shape of the paper can be made almost flat, which has the effect of improving the stacker performance. . In addition, by providing a large cutout, a stacker that can easily take out paper even when a plurality of stackers are stacked up and down can be obtained.
