Description

  The present invention relates to a paper recording medium that can be used hygienically and can selectively and easily erase only unnecessary ruled lines.

  Conventionally, a notebook with ruled lines made of graphite is known as this type of paper recording medium (see, for example, Patent Document 1).

  However, in the notebook described in Patent Document 1, when erasing the characters or charts entered with a pencil or mechanical pencil with an eraser, even the necessary ruled lines are erased together, and only the ruled lines cannot be erased. There was a problem.

  Further, if only the ruled lines are to be erased, it is necessary to erase the ruled lines in advance before entering characters or the like, which causes a problem that the operation becomes complicated.

  In addition, if the ruled line is erased, characters cannot be entered along the ruled line, so the regularity of the part where the character is entered is lost and the written content becomes difficult to understand. .

In addition, because graphite is used to draw ruled lines, not only the hand and clothes are easily contaminated during use, but there are problems with hygiene, as well as the problem that dirt caused by graphite reduces the commercial value of the notebook. there were.

  The present invention has been made in view of the above-described problems of the prior art, and its object is to make paper that can be used hygienically and can easily erase only unnecessary ruled lines. It is to provide a recording medium.

  The above object of the present invention is achieved by the following means.

  The paper recording medium according to claim 1 is characterized in that ruled lines are printed using a printing ink containing a temperature-sensitive color-changing composition, and the paper recording medium according to claim 2 is characterized in that the ruled lines are , Front rule, medium fine rule, back rule, quarter rule, wave rule, child rule, sewing rule, horizontal rule or vertical rule, and claim 3 is a notebook, study notebook, loose leaf, graph paper It is characterized by being a form, a note paper, or a notepad.

  Therefore, since the ruled line is printed using the printing ink containing the temperature-sensitive color-changing composition, the color of the printing ink becomes transparent when the temperature becomes higher than the color changing temperature of the printing ink due to frictional heat or the like. It is kept in a proper state.

  Since the ruled lines are printed using the printing ink containing the temperature-sensitive color-changing composition, the color of the printing ink is transparent when the temperature becomes higher than the color change temperature of the printing ink due to frictional heat or the like. Therefore, only the ruled line printed using the printing ink can be selectively and easily erased and the state can be maintained.

  In addition, after entering characters, etc., only the ruled lines printed using the printing ink can be selectively erased, so that the regularity of the places where characters are entered is not lost, and the written contents There is no hindrance to understanding.

  In addition, since the printing ink is used, it does not adhere to the user's body or a paper recording medium such as a notebook and can be used in a sanitary manner, and the commercial value of the paper recording medium is lowered. There is nothing.

1 is a perspective view showing an embodiment of a paper recording medium according to the present invention and a case where the paper recording medium according to the present invention is applied to a notebook. It is a figure which shows embodiment of the paper recording medium which concerns on this invention, and shows the usage method of the notebook to which the paper recording medium which concerns on this invention is applied.

  Hereinafter, a notebook used for a paper recording medium according to the present invention will be described in detail based on an embodiment with reference to the drawings. The paper recording medium of the present invention is not limited to the following embodiment (note), and various modifications can be made without departing from the scope of the present invention.

  As shown in FIG. 1, a notebook 10 to which a paper recording medium according to the present invention is applied is formed by stacking a plurality of sheets 11 and joining them along the width direction at substantially the center in the length direction. A cover (not shown) is provided on the front side of the notebook 10, and a back cover (not shown) is provided on the back side.

  Also, as shown in FIG. 1, ruled lines 12 having a predetermined length are drawn on both surfaces of the sheet 11 at regular intervals along the width direction of the notebook 10, and the notebook 10 according to the present embodiment. In, ruled lines 12 are printed using a printing ink containing a temperature-sensitive color-changing composition.

  Next, a method of using the notebook 10 to which the paper recording medium according to the present invention is applied will be described.

  First, as shown in FIG. 2, for example, a special eraser 13 for erasing the ruled lines 12 is used to rub the ruled lines 12 to be erased on the sheet 11 in the same manner as erasing characters and the like with a general eraser.

  In the present invention, since the ruled line 12 is printed using the printing ink containing the temperature-sensitive color-changing composition, the frictional heat generated by the dedicated eraser 13 makes the temperature higher than the color change temperature of the printing ink. Then, since the color of the printing ink is maintained in a transparent state, only the ruled lines 12 printed using the printing ink can be selectively and easily erased and the state can be maintained.

  Moreover, since only the ruled lines 12 printed using the printing ink can be selectively erased after entering the characters, the regularity of the portions where the characters are entered is not lost. There is no hindrance to understanding the content.

  Further, since only the ruled line 12 can be selectively erased, for example, the ruled line 12 can be erased to make it easy to see a chart and the like. Etc. can be entered.

  In addition, since the printing ink is used, it does not adhere to the user's body or a paper recording medium such as a notebook and can be used in a sanitary manner, and the commercial value of the paper recording medium is lowered. There is nothing.

  The printing ink containing the thermochromic composition in the paper recording medium according to the above-described embodiment has a thermochromic property and is erased using a special eraser 13 as shown in FIG. If possible, other printing inks may be used, and even if they are used, it is possible to obtain the same operations and effects as described above in the present embodiment.

  Further, in the paper recording medium according to the above-described embodiment, the ruled line 12 as shown in FIGS. 1 and 2 has been described as an example. For example, it may be a ruled line such as a front ruled line, medium thin ruled line, back ruled line, quadrant ruled line, wave ruled line, child ruled line, sewing ruled line, horizontal ruled line, vertical ruled line, etc. Even in the case of a recording medium, it is possible to obtain the same operations and effects as described above in the present embodiment.

  Further, in the paper recording medium according to the above-described embodiment, the notebook 10 as shown in FIGS. 1 and 2 has been described as an example, but the type of the paper recording medium to which the present invention is applied is particularly limited. For example, it may be a notebook, a learning notebook, a loose leaf, a graph paper, a form, a note paper, a memo pad, and the like. It is possible to obtain

  The paper recording medium according to the present invention is capable of selectively and easily erasing only the ruled lines printed using the printing ink, and maintaining the state thereof. Since only the ruled lines printed using printing ink can be selectively erased, the regularity of the places where characters are entered is not lost, the understanding of the written content is not hindered, Since the printing ink is used, it does not adhere to the paper recording medium such as the user's body or notebook, and can be used in a sanitary manner, and the commercial value of the paper recording medium is reduced. As a result, it is extremely useful as a notebook, a learning notebook, a loose leaf, a graph paper, a form, a stationery, and a memo pad, and thus has industrial applicability.
