[0011] The clipboard of the present invention is characterized in that the main body and the pressing part are connected via a bendable folding part.
[0012] The present invention is characterized in that, in the above-mentioned clipboard, the main body has a core material built in, the holding part also has a core material built in, and the folding part does not have a core material built in, and the main body, holding part and cover part are covered with genuine leather or a leather fiber recycled composite material.
[0013] The present invention is characterized in that the above-mentioned clipboard has a first notch cut at a certain length from the top edge of the right side of the cover, a second notch cut at a certain length from the left side of the bottom, and a third notch cut at the corner of the bottom and right sides along the bottom and right sides. [Effects of the Invention]
[0014] According to this invention, the surface of the main body is provided with a flap-shaped holder with a first magnet built into the top, a second magnet built into the inside of the surface of the main body in a position corresponding to the first magnet when the holder is closed, a cover portion covering the back surface is provided on the back surface of the main body, the cover portion is connected to the back surface at the bottom and right sides, the left side and top sides are open, a third magnet is built into the corners of the left side and top sides, and a fourth magnet is built into the back surface in a position corresponding to the third magnet, so that the clipboard is thin on the front side and the holder holds documents firmly, and on the back side documents can be stored by covering them with the cover portion.

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. [Outline of the embodiment] The clipboard according to an embodiment of the present invention (this clipboard) has a flap-shaped retaining portion on the surface of the main body that has a first magnet built into the top, a second magnet built into the inside of the surface of the main body in a position that corresponds to the first magnet when the retaining portion is closed, and a cover portion that covers the back surface is provided on the back surface of the main body, and the cover portion is connected to the back surface at the bottom and right sides, and the left and top sides are open, a third magnet is built into the corners of the left and top sides, and a fourth magnet is built into the back surface in a position that corresponds to the third magnet.As a result, the clipboard is thin on the front surface and can firmly hold documents, and can be stored so that the documents are covered on the back surface.
[0017] [This clipboard: Figures 1-5] This clipboard will be described with reference to Figures 1 to 5. Figure 1 is a schematic diagram of the front side of this clipboard, Figure 2 is a schematic diagram of the front side of this clipboard with the clamping part of this clipboard open, Figure 3 is a schematic diagram of the back side of this clipboard, Figure 4 is a schematic diagram of the right side of this clipboard, and Figure 5 is a schematic diagram of the left side of this clipboard. This clipboard is composed of a main body 10 which is a plate-shaped board portion, a holding portion 11 for the clip portion, and a cover portion 13.
[0018] [Front of this clipboard: Figures 1 and 2] As shown in FIGS. 1 and 2, the surface of this clipboard is composed of a surface portion 10a of a main body 10, a pressing portion 11, and a folding portion 12. The pressing portion 11 is provided in a rectangular shape along the upper side of the main body 10, and has a flap shape that opens and closes around the upper side as an axis.
[0019] As shown in FIG. 2, the surface portion 10a of the clipboard has a pressing portion 11 and a main body 10 connected by a foldable folding portion 12. A core material is built into the main body 10 and the pressing portion 11. However, no core material is built into the folding portion 12. The front and back surfaces 10a and 10b of the main body 10, the pressing portion 11, and the folding portion 12 are made of genuine leather or a composite material of recycled leather fibers.
[0020] Furthermore, as shown in FIG. 2, magnets 11a and 11b are built into both ends of the inside of the pressing portion 11. Furthermore, magnets 10c and 10d are embedded in the surface portion 10a at positions corresponding to the magnets 11a and 11b.
[0021] [Back of this clipboard: Figure 3] As shown in FIG. 3, the rear surface of the clipboard has a cover 13 attached to the rear surface 10b of the main body 10. As shown in FIG. The cover portion 13 is formed to cover the back surface portion 10b, with a right side 13a and a bottom side fixed to the back surface portion 10b, and a left side 13b and a top side not fixed but open. The cover 13 has a front side made of genuine leather or a composite material made of recycled leather fibers, and a back side made of fabric, genuine leather, or a composite material made of recycled leather fibers.
[0022] In addition, to make it easier to open and close the cover portion 13, when viewed from the back surface portion 10b, a notch (first notch) 13c is formed on the right side 13a of the cover portion 13 by cutting a certain length from the top side, a notch (second notch) 13d is formed on the bottom side by cutting a certain length from the left side 13b, and a notch (third notch) 13e is formed at the corner between the bottom side and the right side 13a along the bottom side and the right side 13a. Furthermore, a magnet 13f is embedded in the corner between the top side and left side 13b of the cover portion 13, and a magnet 10e is embedded in the position of the back surface portion 10b corresponding to the magnet 13f.
[0023] [Side view of this clipboard: Figures 4 and 5] As shown in Figures 4 and 5, the sides of this clipboard use magnets 10c, 10d, 11a, and 11b that have built-in adhesion between the pressing portion 11 and the surface portion 10a, and magnets 10e and 13f that also have built-in adhesion between the cover portion 13 and the back portion 10b, so that it can be made thin.
[0024] [How to use this clipboard: Figure 6] How to use this clipboard will be described with reference to Figures 1 to 6. Figure 6 is a schematic diagram of the clipboard with the cover open. In this clipboard, as shown in Figure 2, pressing portion 11 is opened, a document is placed on it, pressing portion 11 is folded closed at folding portion 12, and magnet 11a is attached to magnet 10c and magnet 11b is attached to magnet 10d, thereby clamping and fixing the document. When removing the document, the pressing portion 11 is pushed up and opened, and the placed document is taken out.
[0025] When storing documents in the back surface portion 10b, the cover portion 13 is closed with the magnet 13f built into the upper left corner of the cover portion 13 as viewed from the back surface and the magnet 10e built into the back surface portion 10b adhered together. 6, the user grasps the upper left corner of the cover portion 13 and pulls the attached magnet 13f away from the magnet 10e to open it, then stores the document by sandwiching it between the back surface portion 10b and the cover portion 13, and then adheres the magnet 13f to the magnet 10e to close it.
[0026] When the stored documents are to be removed, the cover portion 13 is opened in the same manner, the stored documents are removed, and the magnet 13f is attached to the magnet 10e, and the cover portion 13 is closed.
[0027] [Effects of the embodiment] According to this clipboard, the surface portion 10a of the main body 10 is provided with a flap-shaped retaining portion 11 having magnets 11a and 11b built into the upper portion, and magnets 10c and 10d are built into the inside of the surface portion 10a of the main body 10 at positions that correspond to the magnets 11a and 11b when the retaining portion 11 is closed. A cover portion 13 that covers the back portion 10b of the main body 10 is provided on the back portion 10b of the main body 10, and the cover portion 13 is connected to the back portion 10b at the bottom and right side 13a, and the left side 13b and top side are open. A magnet 13f is built into the corners of the left side 13b and top side, and a magnet 10e is built into the back portion 10b at a position that corresponds to magnet 13f. Therefore, the surface portion 10a is thin and documents are firmly held by the retaining portion 11, and on the back portion 10b documents can be stored so that they are covered by the cover portion 13.
