When a sheet is put in the cassette 1 and set in the machine, the pressing plate 4 pushes up the sheet 8 by the spring force of the pressing spring 5 and the sheet is fed to the sheet feeding roller 9 provided on the machine side as shown in FIG. The leading edge comes into contact with the sheet, and the sheet feeding roller 9 rotates in the direction of arrow A in this state to feed the uppermost sheet.

[0004]

However, in such a conventional configuration, in order to set the paper in the machine, the packaging is broken, the paper is taken out, the paper is put in the cassette removed from the machine, and then the cassette is set in the machine. Since the operation of setting the paper has to be performed, the paper supply work is troublesome. Also, the conventional cassette is heavy because the cassette base is made of a resin molded body and the iron plate etc. is used in it, and it has a large capacity compared to the volume of the paper stored inside. There was also the problem of requiring great power.

The present invention has been made in view of the above problems, and does not require much effort and is not required to have a large force for a machine such as a copying machine or a facsimile. An object of the present invention is to provide a paper package capable of supplying paper.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention stores a sheet of paper in a box-shaped cassette which is made of thick paper and has an open front end and an upper surface, and wraps it in a wrapping paper. It is characterized in that a pair of notches extending from the front end to the rear end are formed on the bottom surface of the cassette, and the region sandwiched by the notches is a rotatable pressing plate. It is one.

Here, it is preferable that the wrapping paper in which the cassette is wrapped is provided with a separating means for separating the wrapping paper into two parts, front and rear.

[0008]

Since the present invention has the above-mentioned structure, the entire wrapping paper or only the portion covering the front portion of the cassette is removed,
By exposing at least the front of the cassette and the paper in it and setting it in the machine, the paper can be set in the machine, and there is no need to replace the paper in the cassette provided exclusively for the machine as in the past, Further, since the cardboard cassette is lightweight, the paper supply operation becomes extremely easy. Here, since the cassette used in the present invention has a rotatable pressing plate formed on a part of its bottom surface, by providing a means for pushing up the pressing plate on the machine side, the cassette can be mounted on the machine. When set, push up the pressure plate,
It is possible to feed the paper by pressing the paper on the paper against a paper feed roller provided in the machine.

Further, when the paper is transported, since the paper is packed in a cassette made of cardboard, the cassette serves as a reinforcing material, and the paper is less likely to be damaged or bent even if it receives a slight impact. Since the cassette is used to control the transportation after removing the wrapping paper, the paper is less likely to be scattered,
Easy to carry. Furthermore, the cardboard used as the cassette is lightweight and therefore easily recyclable.

As described above, if the wrapping paper in which the cassette is wrapped is provided with a separating means for separating the wrapping paper into two parts, the front and rear parts, and the front part is removed when the wrapping paper is opened. However, it is preferable that the rear part can be set in the machine with the paper covered.
