Abstract

To solve the problem that physical and mental fatigue may be promoted due to difficulty in seeing, writing, and erasing when dealing with a number or a small square number in a book, a magazine, or the like. In addition, there is a possibility that the paper surface is torn by repeated use of the pencil eraser, and the trial play in the book or magazine cannot be continued.SOLUTION: This puzzle is formed in such a size as to be easily seen on a paper surface, easily written with an eraser, and easily erased with an eraser by inserting the puzzle into a clip board together with paper such as a blank paper. It is possible to reduce physical and mental fatigue by working on a number in a book, a magazine, or the like instead of a number or a number space with a small square. Further, since the book or magazine is not directly written with ink or erased with an eraser, the paper surface is not broken or damaged.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] This invention is a net-shaped tool designed to be clipped onto a vertically or horizontally long clipboard to make it easier to write and erase Sudoku answers. [Background technology]

[0002] Sudoku puzzles in books and magazines often have small numbers and squares that are hard to see, write with a pencil, or erase with an eraser. Repeated use of pencils and erasers can also cause the pages to tear. Summary of the Invention [Problem to be solved by the invention]

[0003] Sudoku puzzles with small numbers and squares can be difficult to see, write, and erase, which can lead to physical fatigue, such as eye fatigue, and mental fatigue, such as a lack of concentration. Furthermore, repeated use of pencils and erasers can reduce the durability of the paper, which can lead to tears and other issues, making it impossible to continue playing Sudoku puzzles in books and magazines. These two possibilities are problematic. [Means for solving the problem]

[0004] By placing this invention on top of a separate blank A4 size sheet of paper and inserting it into a vertical or horizontal A4 size clipboard, the net-shaped parts of this invention form blank spaces like Sudoku squares or memo areas that are easy to see, write on, and erase on the paper, thereby solving the problem. [Effects of the Invention]

[0005] It is expected that this will reduce the degree of physical and mental fatigue caused by difficulty in seeing, writing, and erasing. It is believed that Sudoku will become easier for the elderly to tackle.

[0006] Since separate sheets of paper such as blank paper are used, existing books and magazines will not be damaged, and they can be reused.

[0007] There is no need to write the Sudoku squares on a separate sheet of paper, and you can easily tackle the puzzle by simply copying down the numbers in the problem area. Also, since this invention is almost the same shape as an A4 size clipboard, it can be easily carried by clipping it into the clipboard.

[0008] If the paper is blank, it can be reused, even if it is the back of an advertisement or used paper that has only been printed on one side, so it can also be used as part of recycling. [Brief explanation of the drawings]

[0009] [Figure 1] This is a front view of the entire Sudoku net of the present invention. It is roughly the same shape as an A4-sized clipboard. It consists of an outer frame and a net (thick and thin). Furthermore, the present invention is made of a single flexible material and does not include any other parts. DETAILED DESCRIPTION OF THE INVENTION

[0010] The outer frame forms a ruled outer line that surrounds the entire square and the margins like a memo section on the paper. When using a vertical clipboard, the center of outer frame 1a is clipped to the clip part, and when using a horizontal clipboard, the center of outer frame 1c is clipped to the clip part.

[0011] The net (thick) forms 3x3 grid blocks on the paper and internal lines (thick) that represent margins such as memo areas.

[0012] The net (thin) forms internal lines (thin) that represent individual squares on the paper. [Example]

[0013] The orientation of the present invention is changed according to the type of clipboard to be used, and the present invention is clipped into the clip portion together with a separate sheet of paper such as a blank sheet of paper.

[0014] The numbers in the Sudoku puzzle section of a book, magazine, etc. are written into the Sudoku squares formed on a blank piece of paper or the like using the outer frame or net-shaped portion of the present invention.

[0015] Use the blank space in the memo section as needed to solve the Sudoku puzzle. [Explanation of symbols]

Claims

[Claim 1] By placing a blank sheet of paper or the like between the clipboard and the paper, it forms Sudoku squares of an appropriate size on the paper, eliminating the difficulty of seeing the Sudoku pages of books and magazines with small numbers and squares, the difficulty of writing with a pencil or eraser, and the difficulty of erasing. It also prevents damage to the pages of books and magazines, making it easier to work on Sudoku. This net-shaped tool can be used with both vertical and horizontal clipboards.
