Embodiments of the present invention will be described with reference to the drawings. In the drawing, the embodiment of the present invention is represented by a thick line, the printer paper is represented by a thin line, and the printer side mechanism is represented by a thick broken line.
FIG. 1 is a perspective view for explaining the structure of Embodiment 1 of the present invention. As shown in FIG. 2, a bottom surface portion 1, a side surface portion 2, and an upper surface portion 3 so that a bundle 6 of printer paper is exposed to a certain extent from the opening. Set the depth of the printer to be shorter than the long edge of the printer paper.
By this exposure, as shown in FIGS. 10 and 11, normal operation of the paper feed roller 10 of the printer and a paper feed path are secured.
In FIG. 10, the paper feed roller 10 is pressed against the bundle of printer paper 6 in the direction of the white arrow and rotates in the direction of the black arrow, whereby the paper is fed into the printer from the left end of the paper feed tray 11 in the figure. However, when the paper runs out, the paper feed roller 10 contacts the bottom of the paper feed tray 11 and idles.
In FIG. 11, Example 1 is in contact with the paper support 12, and the stack 6 of printer paper is pressed against the paper feed roller 10 by the auto sheet feeder 13 that moves in the direction of the white arrow, and the paper is sequentially fed to the printer paper feed unit 14. The The first embodiment also descends as the last sheet is fed, but it stays in contact with the sheet feed port and is not pulled into the printer.
The normal operation of the paper feed roller 10 indicates that the paper is fed while the paper remains, and idles when the paper runs out.

3, 4, 5, 6, and 17 show a sheet bundle holding notch 5 and a flap 8 for holding a bundle of printer sheets stored in the first embodiment of the present invention with fingers 7. It is a perspective view explaining.
FIG. 3 illustrates a form in which a sheet bundle holding notch 5 is provided from the upper surface portion 3 to the rear surface portion 4. In this case, the stack 6 of printer paper is held directly by the fingers 7 at the upper part and by the fingers 7 through the bottom part 1 at the lower part.
FIG. 4 shows a form in which a flap 8 connected to the upper surface portion 3 is provided in a notch 5 for holding a sheet bundle. In this case, the bundle 6 of printer paper is held by fingers 7 via the bottom surface portion 1 and the flap 8. In addition, the flap 8 can be connected to the bottom surface portion 1 as shown in FIG.
FIG. 5 illustrates a form in which the sheet bundle holding cutout 5 is provided only on the back surface portion 4. In this case, the bundle 6 of printer paper is held by fingers 7 through the bottom surface portion 1 and the top surface portion 3. At that time, the bottom surface portion 1 and the top surface portion 3 are deformed according to the thickness of the bundle 6 of printer paper.
FIG. 6 illustrates a form in which the sheet bundle holding cutouts 5 are provided on the left and right sides of the back surface portion 4. In this case, the bundle 6 of printer paper is held by fingers 7 through the bottom surface portion 1 and the top surface portion 3. At that time, the back surface portion 4 is deformed in accordance with the thickness of the bundle 6 of printer paper.
In the form of FIGS. 4, 5, 6, and 17, the finger 7 does not directly touch the bundle 6 of printer paper, so that the paper is not inadvertently soiled.

7 and 8 are perspective views for explaining the structure of the second embodiment of the present invention, and FIG. 9 shows a state in which a bundle 6 of printer paper is stored in the second embodiment of FIG.
In the second embodiment, by making the size of the bottom surface portion 1 equal to the size of the printer paper that is stored, it is possible to prevent the bundle of printer paper 6 from being inadvertently bent or hitting other objects when the paper is replaced or stored. .

Further, by providing the bottom surface notch 9 in the center of the end of the bottom surface portion 1 in the opening direction as in the second embodiment of FIG. 7, the bundle of printer paper 6 is eliminated as the printing progresses from the state of FIG. Even in this case, since the paper feed roller 10 is idled in contact with the paper feed tray 11 without touching the bottom surface portion 1, the second embodiment is not drawn into the printer. In FIG. 13, the bottom surface portion 1 moves in the direction of the white arrow together with the auto sheet feeder 13, but even if the paper runs out, it is not driven downward by the paper feed roller 11, so Example 2 is not drawn into the printer. The bottom surface notch 9 may have a hole shape as shown in FIG. 8 as long as the paper feed roller 11 does not contact the bottom surface portion 1 and does not interfere with the operation of the double feed prevention mechanism.

Note that the structure for holding the internal printer paper bundle 6 with the fingers 7 in the second embodiment is the same as that in the first embodiment shown in FIGS. 3, 4, 5, 6, and 17.

FIG. 14 is a perspective view for explaining the structure of the third embodiment of the present invention, and FIG. 15 shows a state in which a bundle 6 of printer paper is stored in the third embodiment.
The third embodiment is based on the premise that a relatively small sheet such as a postcard is stored and stored in the printer sheet feeding tray 11 of the front sheet feeding mechanism, and the bottom surface portion 1 is the maximum that can be stored in the printer sheet feeding tray 11. The storage portion formed by the side surface portion 2, the back surface portion 4, and the stopper 15 is the same size as the storage paper.
In the third embodiment, since the rear end portion of the bottom surface portion 1 and the back surface portion 4 are separated from each other, it is difficult to hold the finger bundle 7 even if the paper bundle holding cutout 5 is provided. The stopper 15 is provided at a position where there is no hindrance to prevent the sheet from dropping off when the embodiment 3 is attached to or detached from the paper feed tray 11. As shown in FIG. 16, the stopper 15 is connected to the bottom surface portion 1 at an angle that matches the inclination of the paper feed portion of the paper feed tray 11.
