Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a manual paper feeding device in a copying machine.

(Prior Art) First, a manual paper feeder according to a conventional example will be explained based on FIG.

In the figure, reference numeral 1 denotes a manual feed stand, and a pair of side plates 2, 2 are provided on the manual feed stand 1 so as to be movable in the width direction. The paper 4 is fed into the paper feed roller 3 while being regulated in the width direction by the side plates 2, 2.

However, in such a conventional device, as shown in FIG. 4, the paper 4 sometimes flies out from the side plate 2, resulting in skew feeding or a paper feed jam.

This was particularly the case when the manual feed table 1 had a curved shape as shown in the figure.

Further, as shown in FIG. 5, when setting the paper 4, the leading edge of the paper 4 hits the paper feed roller 3, and the paper is fed without being set properly, resulting in a non-feed jam or a paper feed jam.

(Purpose) The present invention eliminates the drawbacks of the conventional example, and eliminates problems such as non-feeding jams caused by paper setting errors during manual paper feeding,
Paper feed jam, or skewed feeding due to paper guide error.
The purpose is to prevent paper feed jams, etc.

(Structure) In order to achieve the above-mentioned object, the present invention includes a manual feed tray, and a device arranged on the manual feed tray so as to be movable in the width direction of the paper to be fed, and regulating the width direction of the paper to be fed. In a manual paper feeder equipped with a pair of side plates, there is a paper holding plate formed with a protrusion that prevents the fed paper from riding on the side plates, and a paper holding plate extending from the paper holding plate to prevent the fed paper from riding on the side plates. It has a plate-like film that guides the paper.

Hereinafter, the configuration of the present invention will be explained based on illustrated embodiments. Note that the same parts and symbols are the same as in the conventional example.

FIG. 1 is a side view of a manual paper feeder according to an embodiment of the present invention, and FIG. 2 is an external perspective view of the same.

In the present invention, a notch 2a is provided in a part of the side plate 2.
On the other hand, a paper holding plate 5 is provided from above the side plate 2, and a V-shaped protrusion 5a of this paper holding plate 5 is formed.
is engaged with the notch 2a of the side plate 2.

The leg portion at the rear end of this paper holding plate 5 is fixed to the manual feed table 1, and the tip portion is inclined diagonally downward.

A plate-shaped film 6 is provided at the tip of the paper holding plate 5 so as to extend toward the nip portion of the paper feed roller 3.

As the plate-like film 6, for example, a polyester (trade name) film is used. This plate-like film 6 allows the leading end of the paper 4 to be guided to the very edge of the nip of the paper feed roller 3.

The paper is set along the paper holding plate 5, and is reliably guided to the paper feeding position by the plate-shaped film 6 at the tip thereof.

When paper is fed, the paper 4 is prevented from running onto the side plate 2 by the V-shaped protrusion 5a of the paper holding plate 5, so that diagonal feeding does not occur.

Furthermore, as shown in FIG. 2, the paper restraining plate 5 is provided extending outward from both side plates 2, 2, so that any size of paper can be reliably restrained.

(Effects) The present invention is as described above, and according to the present invention, by providing a paper restraining plate formed with a protrusion that prevents the fed paper from riding on the side plate, the paper It is possible to prevent the paper from riding on the side plate, and since a plate-like film is provided extending from the tip of this paper holding plate, the tip of the paper can be accurately guided to the feeding position.

Therefore, it is possible to provide a highly reliable manual paper feeding device that prevents skew feeding, non-feeding jams, and paper feeding jams.
