Description

[Detailed Description of the Invention] The present invention relates to a paper discharge stocker in a copying machine.

The copying machine has a first stocker fixed to the main body, and a second stocker slidably supported by the first stocker, and has a paper size that corresponds to the paper size of the paper to be ejected (for example, copied paper). In addition, a discharged sheet stocker that is adjusted and moved in the direction of expansion and contraction of the second stocker is well known.

In this type of discharge stocker, the first stocker is generally fixed at a predetermined slope, and the second stocker is fixed at a predetermined slope.
It is supported parallel to the stocker, and the discharged paper is configured to slide down on the first stocker due to the above-mentioned slope, and to be stocked by hitting a stopper provided at the tip of the second stocker.

In this case, the second stocker of the paper discharge stocker is slidably supported via a guide member fixed to the back surface of the first stocker, and therefore there is a step between the first stocker and the second stocker.

For this reason, with relatively stiff paper, a gap occurs where the rear edge of the paper is lifted up by the tip of the first stocker. This has the drawback that the paper may get stuck in the paper, disrupting the order of the paper, or causing paper jams, resulting in stock failure.

An object of the present invention is to provide a discharge paper stocker that eliminates the above-mentioned conventional drawbacks.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, a first stocker 1 is fixed to a paper discharge port of a copying machine main body (not shown) with a predetermined slope so that the downstream side is downward in the paper discharge direction. A guide member 2 is fixed to or integrated with the guide member 1 .

A second stocker 3 is slidably supported on the guide member 2 in the same way as the first stocker 1, with the downstream side facing downward in the paper discharge direction, and the tip of the second stocker 3 supports the paper 4 to be discharged. A stopper 5 is provided at the rear end of the paper to prevent it from falling off from the guide member 2.

This second stocker 3 can be slid with a relatively small force,
Moreover, in a stationary state, it is supported by the guide member 2 so as to be held at that position.

In the discharge stocker of the present invention, the second stocker 3 is inclined with respect to the first stocker 1, and in this case, the second stocker 3 is inclined with respect to the first stocker 1.
The stocker 1 is inclined so that the angle formed between the paper mounting surface of the stocker 1 and the horizontal surface is larger than the angle formed between the paper mounting surface of the second stocker 3 and the horizontal surface.

The slope relationship between the first stocker 1 and the second stocker 3 is based on the tangent to the arc drawn by the tip angle 1a of the first stocker 1 and the tip surface 3a of the second stocker 3, as shown in FIG. It is most preferable to be in a similar state.

The paper 4 to be discharged is conveyed onto the first stocker 1 while being nipped by a pair of discharge rollers 7, and is then stocked against the stopper 5 of the second stocker 3.

At this time, even if the paper is made of relatively stiff paper, the small inclination of the second stocker 3 eliminates the opening of the trailing edge of the paper due to the tip angle 1a of the first stocker 1. The paper discharge stocker according to the above provides a good stock of paper.

Here, I would like to add an additional comment regarding the conventional paper discharge stocker. In the conventional paper discharge stocker, the first stocker 11 and the second stocker 13 are parallel to each other as shown in FIG. The tip angle 11a of the first stocker 11 causes the mouth to open.

Then, the next sheet of paper to be ejected gets stuck there, causing a paper jam or disrupting the order of the sheets.

As described above, the paper discharge stocker according to the present invention can reliably eliminate such drawbacks.

Furthermore, the paper discharge stocker of the present invention has a first
The distance between the tip angle 1a of the stocker 1 and the bottom of the second stocker 3 is smaller than the conventional similar distance H shown in FIG. If used for this purpose, the document stocker 8 will be wider by the space Hf than the conventional second stocker 13 shown by the broken line.
It is also easy to take out the original from the machine.

The present invention has the advantage that good stockability can be obtained with a simple structure as described above, and also that when used in a copy stocker of a diazo copying machine, the installation efficiency of the copying machine is improved as shown in FIG.

It goes without saying that the paper discharge stocker of the present invention can be applied not only to a stocker for already copied sheets but also to a stocker for original documents.
