[0002]

2. Description of the Related Art In recent years, computers, registration machines, accounting machines, POS
With the remarkable spread of recording devices such as terminal machines for use, output devices for cash dispensers, facsimile machines, word processors and printers, demand for roll paper as a recording medium has been remarkably increasing. FIG.
As shown in (c), in the conventional roll paper 20, one end of the long paper material 2 in the longitudinal direction is fixed to the cylindrical paper tube 1 by a fixing means 3 such as an adhesive or a double-sided adhesive tape. After being wound, it is generally wound tightly. However, the conventional roll paper 20 is a longitudinal sectional view of FIG.
As shown in (a), when the consumption of the roll paper advances and the number of windings decreases, the phenomenon that the winding of the paper material 2 naturally loosens easily occurs, and particularly, the width and thickness of the large-size paper material and the like. The paper material having a large size or an ink jet recording sheet provided with an ink receiving layer containing a polymer or the like on its surface has a high rigidity, so that the winding is remarkably loosened.

As shown in the enlarged sectional view of FIG. 7 (b), when the paper material 2 is going to move in the winding loosening direction P, a paper tube is attached to one longitudinal end 2A of the paper material 2. Since a force in the direction C separating from the paper material 1 is applied, the paper material 2 may come off from the paper tube 1 as shown in FIG. 7C even when the paper material 2 is wound. Especially roll paper 2 as recording paper
In the case of No. 0, the paper material 2 is generally lightly fixed to one end 2A in the longitudinal direction of the paper material 2 so that the paper material 2 is separated from the paper tube 1 at the end of use. It is easy to peel off from the paper tube 1. Further, when the paper tube 1 rotates in the paper feeding direction D to perform the paper feeding operation in order to align the leading end of the paper in the recording apparatus, the paper material 2 is relatively loosely wound in the direction P.
In particular, in this case, the paper material 2 is easily peeled off from the paper tube 1.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to reduce the possibility that a paper material will not easily come off from a paper tube even if the winding is loosened. It is an object of the present invention to provide a roll paper from which the paper material can be easily peeled off from the paper tube when the material has been used up.

[0005]

According to a first aspect of the present invention, there is provided a roll paper in which a long paper material is wound in a longitudinal direction around a cylindrical paper tube. Wherein the paper material is fixed to the paper tube by fixing means at one end in the longitudinal direction of the paper material, and the paper material is wound in a direction in which the paper material is folded. And

According to such a configuration, since the number of windings is reduced, even if the winding of the paper material is naturally loosened, a force is applied to the folded portion of the nori shiro in the direction of the center of the circular section of the paper tube. Therefore, the paper core is closely attached to the paste, and the paper material is not easily peeled off from the paper core. On the other hand, at the end of use of the paper material, a force is applied to the folded part of the nori shiro in the direction away from the paper tube, so that the paper material can be peeled off from the paper tube with less force than conventional roll paper. it can.

Further, the present inventors have found that the object can be achieved by employing a known adhesive and / or a double-sided adhesive tape as the fixing means. Therefore, the roll paper according to claim 2 is characterized in that the fixing means is made of an adhesive and / or a double-sided adhesive tape.

Further, the roll paper according to claim 3 is characterized in that the paper material is an ink jet recording paper. Ink jet recording paper generally has high rigidity due to the provision of an ink receiving layer containing a polymer or the like on its surface, so that when roll paper is used, the paper material is easily wound. However, according to the above configuration, it is possible to use a roll paper in which the ink jet recording paper is hard to be detached from the paper tube even if the winding is loosened.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below in detail with reference to FIGS. FIG. 1 is a perspective view showing a process of manufacturing the roll paper according to the present invention. First, one end of the paper material 2 in the longitudinal direction is turned back to provide a nori shiro 4 (see FIG. 1A). A double-sided adhesive tape 3 as a fixing means is attached to the paper tube 1 along the longitudinal direction of the paper tube 1. Then, the paste 4 is adhered to the paper tube 1 via the double-sided adhesive tape 3 (see FIG. 1 (b)), and the long paper material 2 is densely wound around the paper tube 1 to thereby achieve the present invention. (See FIG. 1 (c)).

According to such a configuration, as shown in FIG. 2A which is a longitudinal sectional view of the roll paper 10 and FIG. 2B which is an enlarged view thereof, consumption of the roll paper 10 progresses. Due to the reduced number of windings, even if the paper material 2 moves in the direction P in which the winding is loosened, as shown in FIG. Since the force is applied in the direction A, the glue 4 and the paper tube 1 come into close contact with each other, so that the paper material 2 is hardly peeled off from the paper tube 1. In addition, the recording paper for inkjet generally has a high rigidity by providing an ink receiving layer having a polymer or the like as a constituent component on the surface thereof. By using the roll paper 10 having the configuration, it is possible to obtain the roll paper 10 in which the ink-jet recording paper, which is the paper material 2, does not easily come off the paper tube 1 even if the winding is loosened.

On the other hand, when the paper material 2 has been used, a force is applied to the folded portion 5 of the nori shiro 4 in the direction B away from the paper tube 1 (see FIG. 3A). In comparison, the paper material 2 can be peeled off from the paper tube 1 with a weak force (see FIG. 3B).

As described above, according to the roll paper 10 according to the embodiment of the present invention, even if the number of remaining rolls of the roll paper is reduced and the paper material 2 is loosened, it is difficult for the paper material 2 to be peeled off from the paper tube 1 and the paper is hardly removed. When the material 2 has been used, the paper material 2 can be easily peeled off from the paper tube 1.

The roll paper according to the present invention is not limited to the above-described embodiment, but can be appropriately modified and improved. For example, according to the width, thickness, material, and the like of the paper material, as shown in FIG. The paper may be rolled paper stuck to both ends of the paper tube 1 via.

Further, as shown in the longitudinal cross-sectional enlarged view of the roll paper in FIG. 5, the roll paper in which the specific region 4A of the nori sill 4 on the folded portion 5 side is not fixed to the paper tube 1 is also provided by the present invention. It is included in the technical idea.

As the paper tube 1, any known one can be used. The paper material 2 is not limited to the above-described ink jet recording paper, but may be any of various paper materials, for example, a large-size paper material or a registration roll paper. It can be applied to all types of roll paper, such as general high-quality paper, thermal paper used for thermal FAX, and other specialty paper. Further, the fixing means is not limited to the double-sided tape described above, and a known adhesive or glue can be used.

[0016]

According to the roll paper according to the first aspect, in a roll paper in which a long paper material is wound in a longitudinal direction around a cylindrical paper tube, one end of the paper material in the longitudinal direction is wound. Since the folded norishiro is fixed to the paper tube by the fixing means, and the paper material is wound in the direction in which the norishiro is folded, the number of windings is reduced, so that the paper material is wound. Even if the time loosens naturally, a force is applied to the folded portion of the Norishiro in the direction of the center of the circular cross section of the paper tube, so that the Norishiro and the paper tube are in close contact with each other and the paper material is less likely to be peeled from the paper tube. On the other hand, at the end of use of the paper material, a force is applied to the folded part of the nori shiro in the direction away from the paper tube, so that the paper material can be peeled off from the paper tube with less force than conventional roll paper. it can. Therefore, it is possible to provide a roll paper in which the paper material does not easily come off the paper tube even if the winding is loosened, and the paper material can be easily peeled off from the paper tube when the paper material is used up.

According to the roll paper according to the second aspect, it is possible to provide a roll paper that can employ a known adhesive and / or a double-sided adhesive tape as the fixing means.

According to the roll paper according to the third aspect, since the paper material is an ink jet recording paper, it is possible to provide a roll paper in which the ink jet recording paper hardly comes off the paper tube even if the winding is loosened. .
