Description

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

(Prior art) When using a long photosensitive paper in a diazo type copying machine, for example, the long photosensitive paper is placed in a normal size photosensitive paper container such as a paper feed cassette. If paper is to be stored,
There is not enough storage space for the photosensitive paper, and depending on the length of the photosensitive paper, the trailing edge of the photosensitive paper may sag due to its own weight, so it is necessary to hold it by hand when feeding the photosensitive paper. be.

(Purpose) The purpose of this invention is to use a paper container of normal size.
To provide a long paper feeding container capable of storing long paper of arbitrary length to be fed and feeding the long paper into a copying machine without having to hold the long paper by hand. .

(Structure) In order to achieve the above object, the present invention opens the rear end of the paper container upwards, and also includes a receiver for folding long paper at the rear end of the paper container. It is characterized by a rail that can be moved in and out.

The present invention will be explained below based on one embodiment.

FIG. 1 shows a schematic diagram of a diazo copying machine equipped with a long paper feeding container according to an embodiment of the present invention. 2, the original paper is fed into the copying machine main body 5 from the original paper table 3 by a pair of original paper feeding rollers 4, respectively.

The front end portion 1A of the photosensitive paper feeding container 1 is attached to the copying machine main body 2, and in this attached state, it is placed below the original paper table 3. Photosensitive paper feeding container 1
As shown in FIG. 2, it has side walls 1a and 1b on both sides for guiding both side edges of the photosensitive paper, and the rear end is open to the top as shown in the figure.

At the bottom 1c of the rear end of the photosensitive paper feeding container 1, there is a receiving rail 6 which is made by bending the middle part of a piece of wire upward into a rectangular shape and curving the rising part outward. The leg portion 6a is fitted so as to be freely removable.

The photosensitive paper placed in the photosensitive paper feeding container 1 with its leading edge in contact with the photosensitive paper feed roller 2 is rotated midway so that its rear end faces toward the front end 1A of the container 1. The portion is folded back, and the folded portion is supported by the curved portion 6b of the receiving rail 6. This folded back position can be freely adjusted by pulling out or pushing in the receiving rail 6 as appropriate.

According to this invention, since the long length of photosensitive paper is folded and stored, the rear end does not hang down from the container 1, and therefore, when feeding the photosensitive paper, it can be held by hand. Also, there is no need to
It does not need to be very large even as a container for feeding photosensitive paper. Note that a plurality of sheets of photosensitive paper may be placed on this container. By the way, the long paper feeding container 1 according to the embodiment of the present invention includes:
As shown in FIG. 2, an elongated support plate 7 is fixedly suspended horizontally on the upper portions of both side walls 1a and 1b.
A locking piece 7 stands up in the center of the support plate 7.
a is formed.

Here, the photosensitive paper is placed on the fixed mounting plate 8 and the movable mounting plate 9 shown in FIG. Place it on top. Next, when the receiving rail 6 that had been pulled out toward the front in FIG. 2 is pushed in and the folded part is moved, the movement of the rear end of the photosensitive paper is regulated by the locking piece 7a, so that The leading edge of the photosensitive paper slides on the movable placement plate 9 and eventually comes into contact with the photosensitive paper feed roller 2.

Now, assuming that there is no support plate 7 with the locking piece 7a, the leading edge of the photosensitive paper is placed on the photosensitive paper feed roller 2.
If the photosensitive paper is placed at an arbitrary position in front of the photosensitive paper, then the paper is folded back and the rear end is placed on top of the photosensitive paper. If the frictional force between the paper and the placing plate 9 is large, the rear end of the folded photosensitive paper will simply slide over the photosensitive paper, and no matter how long the leading edge of the photosensitive paper passes, the photosensitive paper feed roller There is no chance of hitting 2.

By providing the locking piece 7a on the support plate 7, when the receiving rail 6 is pushed in, the movement of the rear end of the photosensitive paper is regulated by the locking piece 7a, so that the leading edge of the photosensitive paper is movably placed. It advances while sliding on the plate 9 and eventually hits the photosensitive paper feeding roller 2. In other words, there is no need for the leading edge of the photosensitive paper to touch the paper feed roller 2 from the beginning; if you place it at any position in front of it, pushing the presser rail 6 will ensure that the leading edge of the photosensitive paper touches the paper feeding roller 2. It's true. Also, assume that there is no support plate 7. If you fold the photosensitive paper with the leading edge of the photosensitive paper against the photosensitive paper feed roller 2 and place the trailing edge on top of the photosensitive paper, the photosensitive paper will remain folded. , resulting in a situation where the product is sent away. By providing the support plate 7,
This kind of problem is avoided. The movable mounting plate 9 is swingable about one end 9a in FIG. .

(Effects) As described above, since the present invention has a structure that can fold and store long sheets of paper, the rear end of the long sheets of paper does not hang down from the container, and therefore There is no need to hold it by hand when feeding paper, and there is no need to make it very large as a paper feeding container.
