Description

[Detailed Description of the Invention] The present invention relates to a feeding device for supplying printed paper to a printing device, and particularly for folding paper (fan-fold paper).
This invention relates to a printing paper supply device that can store and hold printed paper compactly and can take it out very smoothly with little force.

In recent years, as devices equipped with printers have become smaller, there has been a strong demand for smaller printed paper and printed paper supply devices.

However, the problem with these miniaturizations is whether a sufficient length of printing paper can be secured. Therefore, folding paper (fanfold paper) is currently attracting attention. This folding paper is made by folding and stacking long sheets of paper one after another to a predetermined length, and has the characteristic that the length is sufficient compared to the thickness of the stack. Therefore, this folded paper is highly desirable as printing paper for small printing devices.

However, as shown in FIG. 1, when this folded paper 1 is simply housed and held flat in a cassette main body, which is a feeding device, and is taken out from the opening, the folded portion 4 of the folded paper 1 is inserted into the cassette main body. Since the paper comes into contact with the ceiling, a very large amount of force is required to pull out the paper, which has the disadvantage of not being able to feed the paper smoothly. Therefore, in order to eliminate this drawback, it is sufficient to increase the space from the top surface of the folded paper to the ceiling of the cassette main body, but with this configuration, the cassette main body 2 becomes extremely large, and the printing paper supply for the small printing device becomes difficult. It is not acceptable as a device.

Therefore, an object of the present invention is to provide a small-sized printed paper supply device, which is constructed so that folded paper stored and held can be smoothly taken out with a very small force. be.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2A is a longitudinal sectional view of the printing paper supply device according to the present invention, and FIG. 2B is a view seen from the opening side. In the figure, reference numeral 5 indicates the main body of the supply device, and as shown in the figure, this supply device has a box-like shape with a depth at least equal to the length of the folded paper 6 folded in half and a height sufficient to accommodate the folded paper 6. It has a substantially U-shaped bottom 8 facing the opening 7. On the other hand, claws 9, 9 are provided at both opening ends of the opening 7, and it is considered that the feeding device main body 5, which stores and holds the folded paper, can be attached to the printing device using these claws 9, 9. has been done.

When the folded paper 6 is bent in two at the center and inserted into the supply device 5 having the above structure through the opening 7, the bottom portion 8 of the supply device is now formed in a U shape, so the folded paper 6 is folded in a U shape. Stored and maintained in its original condition. Therefore, when one end of the folded paper 6 is pulled, the folding space 10 is used to pull out the paper from the inside without almost any resistance, as shown in FIG. 2A. In this case, the paper pulling force can be controlled to some extent by appropriately selecting the dimensions of the folding space 10, but by holding the folded paper 6 in a U-shape, the dimensions of the space 10 can be considerably reduced. However, the paper drawer is smooth.

Therefore, according to this feeding device 5, the height of the device can be considerably reduced and its depth can be halved even though it stores and holds a large amount of folded paper 6 compared to the conventional device. The most important thing is that the folded paper 6 can be pulled out smoothly with a very small force.

FIG. 3 shows another embodiment, in which one main body 5' is obtained by dividing the main body of the feeding device shown in FIG. 2 into upper and lower parts.
and the other main body 5'' are rotatably attached and rotated in the direction of the arrow in the figure.
It was designed to be assembled. This configuration has the feature that the folded paper 6 can be easily stored and held by opening the device, placing the folded paper 6 therein, and then closing the device.

Note that the claws 9, 9 of the supply device may be formed in any part, and therefore, depending on where they are formed, the supply device can be attached to an appropriate location such as the side or bottom of the printing device. . Further, in the case of a notebook-type calculator equipped with a printer, the supply device can be placed between the main body of the calculator and the notebook for compact use.

As described above, according to the printing paper supply device according to the present invention, although the external size is very small,
It can store and hold a large amount of folded paper, and it can also smoothly pull out the paper with very little force. Therefore, it is most suitable as a feeding device for small-sized printing devices. Further, the printing paper supply device according to the present invention is attached to a printing device by a tab, and can be removed from the printing device. Therefore, the supply device can be made into a cassette, and different types of folded paper (for example, blank paper, ruled paper, etc.) can be stored in multiple supply devices, and the desired paper can be selected from among the supply devices. By selecting the appropriate printing paper, it is possible to easily supply printing paper suitable for the printing content to the printing device, which is extremely convenient.
