Description

  The present invention relates to a writing sheet, and particularly suitable for use in teaching in elementary and junior high schools and the like when teaching materials such as textbooks and tests are enlarged and projected onto a screen or the like using an image projection device. About.

  In recent years, the introduction of education (ICT education) using information and communication technology (ICT) is being promoted in elementary and junior high schools, etc. As part of this, textbooks and test materials are used as ICT equipment. Enlarging and projecting onto a screen or the like by using an “image projection device” and instructing children.

The image projection apparatus for ICT education is disclosed in, for example, Japanese Patent Application Laid-Open No. 2014-112781 (Patent Document 1) previously proposed by the applicant.
As shown in Patent Document 1, the ICT education image projection apparatus enlarges the document camera 2 that captures the target page of the book teaching material 5 as a color image, and the color image sent from the document camera 2. An image projector 3 for displaying on the screen T is provided (see paragraphs 0019 to 0024 and FIGS. 1 to 3 of Patent Document 1).

  By enlarging and projecting the target page of the teaching material on the screen using the above-mentioned image projection device for ICT education, it is possible to easily grasp and concentrate on the page or problem that is the learning target. Effective teaching is possible.

JP 2014-112781 A

By the way, in the process of instructing a child / student using the image projection apparatus, there is a case where the teacher wants to write and teach the teaching material to be projected.
For example, if the teacher wants to write a “correct answer” on a textbook to be projected or a problem during a test, or if the teacher points to a point on the map or material to be projected, the teacher marks “Akamaru etc.” If you want to.

However, writing directly on the teaching material itself is not preferable in the following points.
(1) When the writing instrument to be written is a pencil, the writing material can be erased or damaged, although it can be erased with an eraser.
(2) When the writing instrument for writing is an ink pen, it is difficult to erase the writing once written.

  The present invention has been devised to solve the above-mentioned problems, and the purpose of the present invention is to make it appear as if the candy is also written on the object by writing it with a pencil and an ink pen on the object such as teaching materials. Another object of the present invention is to realize a writing sheet that can be erased freely by a pencil and an ink pen.

In order to achieve the above object, the writing sheet according to claim 1 comprises:
A transparent sheet member is formed with a pencil writing surface erasable by pencil and an erasable pencil writing surface and an erasable ink pen writing surface by an ink pen writing and wiping tool.

The writing sheet according to claim 2,
A transparent first sheet member having a pencil writing surface and an erasable pencil writing surface formed by an eraser formed on the surface, and an erasable ink pen writing surface formed by an ink pen and a wiping tool formed on the surface. A transparent second sheet member is provided, and one side edge of the first sheet member and one side edge of the second sheet member are connected to each other.

The writing sheet according to claim 3 is the writing sheet according to claim 2,
One side edge of the first sheet member and one side edge of the second sheet member are pressure-bonded and connected.

The writing sheet according to claim 4 is the writing sheet according to any one of claims 1 to 3,
The sheet member is made of a flexible material.

  Since the writing sheet according to claim 1 is formed on a transparent sheet member with pencil writing and erasable pencil writing surface with an eraser, and ink pen writing and erasable ink pen writing surface with a wiping tool, By writing the pencil writing surface or the ink pen writing surface on an object such as a teaching material and writing it with a pencil or ink pen, it is possible to make it appear as if the wrinkle has been written on the object. Writing can be erased freely.

The writing sheet according to claim 2 is a transparent first sheet member having a pencil writing surface and an erasable pencil writing surface formed by an eraser formed on the surface, and an ink pen writing and wiping tool on the surface. Since it comprises a transparent second sheet member on which an erasable ink pen writing surface is formed, and constructed by connecting one side edge of the first sheet member and one side edge of the second sheet member, An object such as a teaching material is sandwiched between the first sheet member and the second sheet member, and pencil writing on the surface is performed with the first sheet member or the second sheet member covered on the object. By writing on the writing surface of the surface or ink pen with a pencil or ink pen, it is possible to make it appear that the scissors have been written on the object, and to erase the writing of the pencil and ink pen freely using an eraser or wiping tool It can be.
In addition, since the writing sheet according to the second aspect is used by sandwiching an object such as a teaching material between the first sheet member and the second sheet member, the object is also difficult to shift.

  As in the writing sheet according to claim 3, in the writing sheet according to claim 2, one side edge of the first sheet member and one side edge of the second sheet member are connected by being “crimped”. In this case, the closeness between the first sheet member and the second sheet member is high. For this reason, when both sheet members are placed on a predetermined page of the teaching material, for example, the contact surface between the sheet member and the page It is difficult to create a gap in the image, and when the page is photographed by the document camera of the image projection apparatus, it can be clearly copied.

  When the sheet member is made of a flexible material as in the writing sheet according to the fourth aspect, the sheet member can be covered along the curved surface even if the object to be covered is a curved surface.

Hereinafter, an example of an embodiment of a writing sheet 10 according to the present invention will be described based on the accompanying drawings.
FIG. 1 is a perspective view showing a writing sheet 10 according to the present invention. The writing sheet 10 includes a transparent rectangular first sheet member 12 made of a flexible material and a transparent sheet made of a flexible material. A rectangular second sheet member 14 is provided, and the one side edge 12a of the first sheet member 12 and the one side edge 14a of the second sheet member 14 are connected by pressure bonding. By opening and closing both sheet members 12, 14 with the one side edges 12a, 14a as the base end, textbooks, test materials, etc. are sandwiched between the first sheet member 12 and the second sheet member 14 Can be done.
The size of the first sheet member 12 and the second sheet member 14 can be arbitrarily selected according to the size of the teaching material to be sandwiched and used. For example, from the A4 size suitable for sandwiching the textbook Various A3 sizes suitable for inserting test paper (A3 reduced size) can be selected.

  As shown in FIG. 1, a notch 18 is formed at the upper edge 12c of the first sheet member 12, a notch 20 is formed at the lower edge 12d, and an upper edge 14c of the second sheet member 14 is formed at the upper edge 14c. A notch 21 is formed in the lower end edge 14d.

The first sheet member 12 and the second sheet member 14 are made of, for example, a transparent resin material such as polypropylene resin, but are not limited to the resin material, and an appropriate transparent material can be used. .
In the present invention, the term “transparent” refers to a degree of transparency that allows the object to be seen through when the first sheet member 12 and the second sheet member 14 are placed on the object such as a teaching material. If an object can be seen through, it may be translucent, and it may be colorless and transparent or colored and transparent.

As shown in FIGS. 1 and 2, the surface of the first sheet member 12 excluding the one side edge 12a connected to the one side edge 14a of the second sheet member 14 is a pencil (black pencil or colored pencil). An erasable pencil writing surface 22 is formed by writing and erasing.
That is, the pencil writing surface 22 is a rough surface on which many fine irregularities are formed, and the pencil core material particles are scraped off and remain on the fine irregularities so that writing with a pencil is possible. At the same time, the eraser can be erased with an eraser in order to adsorb and remove the pencil core particles remaining on the fine irregularities.
In addition, since the pencil writing surface 22 is formed with a large number of fine irregularities, it is possible to reduce reflections by irregularly reflecting light from an electric lamp or the like, and to make it easier to see the writing contents of the pencil.
It is possible to write on the pencil writing surface 22 even with an ink pen, but it is extremely difficult to erase because the ink enters the fine irregularities and adheres firmly.

The pencil writing surface 22 is formed, for example, by embossing or matting (sandblasting) the first sheet member 12 made of a transparent resin material to give fine irregularities to the surface. be able to.
Further, the pencil writing surface 22 having fine irregularities may be formed on the surface of the first sheet member 12 by applying a transparent varnish.

  As shown in FIGS. 1 and 3, the surface of the second sheet member 14 excluding the one side edge 14a connected to the one side edge 12a of the first sheet member 12 is water-based such as a commercially available wide board marker. Alternatively, the ink pen writing surface 24 can be freely written with an oil-based ink pen and wiped and erased with a wiping tool such as cloth or paper.

The ink pen writing surface 24 is, for example, a smooth surface obtained by smoothing the surface of the second sheet member 14 made of a transparent resin material, and the ink is attached to the smooth surface by an ink pen. In addition, it is possible to erase the attached ink by wiping with a wiping tool such as cloth or paper.
Since the ink pen writing surface 24 is a smooth surface, the pencil core slips and the core material particles cannot be rubbed, and writing with a pencil is difficult.

The first sheet member 12 and the second sheet member 14 constituting the writing sheet 10 of the present invention are made of the same sheet material.
That is, as shown in FIG. 4, an ink pen writing surface 24 is formed on the back surface side of the first sheet member 12 having a pencil writing surface 22 formed on the front surface side, and an ink pen writing surface 24 is formed on the front surface side. A pencil writing surface 22 is formed on the back surface side of the formed second sheet member 14, and the ink pen writing surface 24 on the back surface of the first sheet member 12 and the pencil writing surface of the second sheet member 14. The writing sheet of the present invention is obtained by pressing and connecting the one side edge 12a of the first sheet member 12 and the one side edge 14a of the second sheet member 14 in a heated and melted state with the two facing each other. You can get 10.

In the writing sheet 10 of the present invention, as shown in FIG. 5, a textbook 26 having a predetermined page opened is sandwiched between a first sheet member 12 and a second sheet member 14. It is used in a state where a first sheet member 12 having a pencil writing surface 22 formed on the surface is covered on a predetermined page.
As described above, since the first sheet member 12 and the second sheet member 14 are made of a flexible material, even if the page surface covering both the sheet members 12 and 14 is a curved surface, Can be covered along.

As described above, the writing sheet 10 of the present invention is used by sandwiching the teaching material as the object between the first sheet member 12 and the second sheet member 14, so that the teaching material is not easily displaced.
Further, as described above, since the one side edge 12a of the first sheet member 12 and the one side edge 12a of the second sheet member 14 are connected by “crimping”, the first sheet member 12 and the second sheet member 12 are connected. The closeness between the sheet members 14 is high. For this reason, when both the sheet members 12 and 14 are placed on a predetermined page of the teaching material, a gap is not easily generated on the contact surface between the sheet members 12 and 14 and the page, and the document camera When you take the above page, you can copy it clearly.

As described above, the first sheet member 12 and the second sheet member 14 having a rectangular shape are connected to only one side edge 12a, 14a, and the other side edge 12b, 14b, upper end edge 12c, 14c. Since the lower end edges 12d and 14d are open, teaching materials can be easily inserted and removed from various directions.
In addition, since the three sides of the other side edges 12b and 14b, the upper end edges 12c and 14c, and the lower end edges 12d and 14d are open, it is easy to sandwich and take out the teaching material having a special shape (such as a long book).

  For convenience of explanation in comparison with the ink pen writing surface 24, in FIG. 1, FIG. 2, FIG. 4 and FIG. 5, the pencil writing surface 22 is represented by a dot pattern.
