Description

Detailed Description of the Invention The present invention relates to a cartridge type supply device for supplying recording paper to a recording device such as a printer, particularly fan-fold type recording paper (continuous paper folded alternately at perforations). The present invention relates to a recording paper feeding device suitable for feeding paper.

In recent years, small notebook-shaped devices have already been proposed as devices equipped with recording devices such as printers, but on the other hand, there has been a delay in making the supply devices that supply recording paper to these devices smaller and thinner. it is,
The main reason is that roll paper was used as the recording paper.

Therefore, in the present invention, we focused on the fact that fanfold type recording paper, that is, continuous paper that is alternately folded at the perforations, is suitable for making the above-mentioned feeding device smaller and thinner. By configuring a feeding device suitable for feeding recording paper, the present invention aims to make the feeding device smaller and thinner, thereby providing a recording paper feeding device that is most suitable for a portable recording device.

The recording paper supply device according to the present invention is characterized by, for example, as shown in FIG. When it is pulled out, the next folded part 4 is completely prevented from being pulled out at the same time, and as shown in Fig. 2, it is necessary to leave a large space between the upper surface of the folded paper 3 and the top plate of the cartridge body. The cartridge 1 is made smaller and thinner by solving the drawback that when paper is pulled out, the folded part 5 hits the top plate and the paper cannot be pulled out smoothly.

An embodiment of the apparatus of the present invention will be described in detail below based on the drawings.

Fig. 3 shows an example in which the recording paper supply device according to the present invention is installed in a notebook-type calculator with a printer. , 8 is the calculator body, 9 is the fanfold paper outlet, 1
0 is a display section of a calculator, 11 is a keyboard, and 12 is a notebook. As shown in the figure, the supply device main body 1 is mounted with one part thereof inserted into the calculator main body 8 and the other part not inserted into the calculator main body 8.

Next, the structure of the recording paper supply device 1 will be explained in detail based on FIGS. 4 and 5. The device main body 1 is made of a resin material such as plastic and has a rectangular parallelepiped shape. Elastic engagement pieces 13 are integrally formed on both side walls for removably attaching to a recording device or a device equipped with a recording device (see Fig. 4), and the bottom wall is provided with an elastic engagement piece 13 for convenient portability. That is, a clip 14 is elastically formed integrally so that it can be attached to the lid of a notebook or a pocket (see FIG. 5).

On the other hand, a recording paper outlet 2 is provided on one end side of the upper surface of the device main body (the side inserted into the calculator main body 8) for taking out the fanfold paper 3 inside and supplying it to the recording device. Further, an opening 15 is provided at a position facing the recording paper outlet 2 (the upper end of the side not inserted into the calculator main body 8), which serves as an escape for the folded portion A of the fanfold paper 3. . Further, over the entire surface of the opening 15, no other member is provided above it. Reference numeral 7 designates a collar provided to prevent the folded portion 6 of the folded paper 3 located near the recording paper outlet 2 from being unnecessarily pulled out due to friction. This collar 7 has the same effect as the collar 7 explained in FIG. ing.

Now, fanfold paper 3 in the direction of the arrow in Figure 5
When the folded part A is pulled out, the folded part A first faces the outside through the opening 15, and the surrounding part forms a large arc as shown by the dotted line in the figure. The folded portion A, which was initially bent into an edge shape, is stretched out into a substantially straight line as shown by B in the figure, and then drawn into the main body 1 of the apparatus again as shown by C in the figure, and eventually the recording paper It is taken out to the outside through the takeout port 2.

In this case, the folded portion A of the folded paper 3 is stretched linearly without any resistance.
Even if the distance T between the upper surface of the stacked and stored fanfold paper 3 and the top plate of the apparatus main body 1 is very narrow, the paper can be taken out very smoothly without any resistance.

In addition, since the folded part 6 of the folded paper is appropriately regulated by the collar 7 provided at the end of the recording paper outlet, the other parts are also The drawback that the recording paper is pulled out and interferes with the supply of recording paper is completely eliminated.

As described above, the recording paper feeding device according to the present invention has a structure in which no other member is provided above the entire surface of the opening for exposing the folded portion of the recording paper to the outside. The entire feeding device can be made thinner,
In addition to being convenient when stacking and carrying around, the opening is provided on the side that is not inserted into the recording device, so when the recording paper is pulled out, there are no restrictions on the folded portion of the recording paper that faces outside from the opening. This results in an effect that no resistance is applied to the folded portion of the recording paper when the recording paper is pulled out.
