DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper holder for a printer, and more particularly, to a paper sheet for a printer for storing a foldable continuous form-type recording paper and supplying the recording paper to a platen from the back of the printer mounted on the upper surface. Regarding the holder.

2. Description of the Related Art FIG. 2 is a sectional view showing an example of a paper holder of a conventional printer.

A paper holder 21 of a conventional printer for storing a foldable continuous form-type recording sheet and supplying the recording sheet to a platen from the back of a printer mounted on the upper surface.
As shown in FIG. 2, the paper storage unit 22 has an “L” shape in which a paper guide unit 23 protruding upward is provided at the rear of the box-shaped paper storage unit 22. The printer 11 is mounted thereon, and the recording paper 4 stored in the paper storage unit 22 is supplied from the paper guide unit 23 to the printer 11.

The printer 11 winds the first form 6 of the recording paper 4 supplied from the suction port 15 around the platen 13,
Printing is performed by the print head 14 of the printing unit 12 and the platen 13 is conveyed by rotating the platen 13.

When printing in the printer 11 proceeds and the first sheet 6 is conveyed, the second sheet 5 continuous with the first sheet 6 is transferred to the upper surface plate 22a of the sheet storage 22 and the sheet guide. The paper guide unit 23 is guided along a guide 29 provided on the inner surface of the wall surface on the printer 11 side of the unit 23,
After reaching the suction port 15 of the printer 11, it is supplied to the next printing.

At this time, the 3
Since the inside of the paper guide section 23 is wide, the fourth sheet 8 is dragged by the second sheet 5 and the paper guide section 23 is moved.
May get inside.

[0007]

As described above, in the paper holder of the conventional printer, since the inside of the paper guide portion is wide, the next form continuous with the form supplied to the printer is not used. However, there is a problem that the sheet may be dragged by the previous form and enter the paper guide portion, and a large number of forms may be simultaneously conveyed to cause a jam.

[0008]

A paper holder of a printer according to the present invention includes a box-shaped paper storage section for storing a foldable continuous form-type recording paper and mounting a printer on an upper surface thereof, and a rear portion of the paper storage section. In a paper holder of an "L" -shaped printer having a paper guide portion provided with a guide on the inner surface of the wall surface of the printer by projecting upward at a position facing the guide inside the paper guide portion. A projection is provided, and the recording paper is one between the guide and the projection.
A transport path is formed at a narrow interval enough to allow only one sheet to pass.

[0009]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the present invention.

In FIG. 1, the appearance of the paper holder 1 is the same as that of the conventional example of FIG. 2, but the internal structure is different.
That is, the paper holder 1 has an “L” shape in which a paper guide portion 3 protruding upward is provided at a rear portion of the box-shaped paper storage portion 2. The printer 11 is mounted.

The paper storage unit 2 has the same structure as the conventional example of FIG. 2, and stores the recording paper 4 inside. Paper guide 3
The guide 9 is provided on the inner surface of the wall surface on the side of the printer 11 in the same manner as in the conventional example of FIG. In addition, between the guide 9 and the protruding portion 10, there is a conveyance path 7 having such a small interval that only one recording sheet 4 can pass.

The recording paper 4 stored in the paper holder 1 constructed as described above is supplied from the suction port 15 of the printer 11 through the transport path 7 and wound around the platen 13 to be printed by the print head 14 of the printing unit 12. It is printed and transported by
The printing in the printer 11 proceeds, the first sheet 6 is conveyed, and the second sheet 5 continuous with the first sheet 6 is
When the sheet passes through the transport path 7 in the sheet guide section 3 along the upper surface plate 2a of the sheet storage section 2 and the guide 9 and reaches the suction port 15 of the printer 11 and is supplied for the next printing, the second sheet The third and fourth sheets 8 continuous with the sheet No. 5
The conveyance path 7 is narrowed, and is prevented from being dragged by the second sheet 5 and entering the paper guide section 3. Therefore, a large number of documents are not conveyed at the same time to cause a jam.

[0014]

As described above, the paper holder of the printer according to the present invention is provided with a protrusion on the inner surface of the outer wall surface, facing the guide on the inner surface of the printer-side wall surface of the paper guide portion, and is provided with the guide. By forming a conveyance path with a narrow interval that allows only one sheet of recording paper to pass between the projection and the projection, a large number of documents are prevented from simultaneously entering the paper guide unit. This has the effect of preventing the paper from being transported at the same time and causing a jam.
