Abstract
Description
Technical Field
[0001] It is a product that helps to acquire the way of adding strength such as the thickness and thinness of characters that change according to the way of applying force such as pen pressure when practicing or learning calligraphy (hereinafter referred to as floating and sinking).
[0002] The depth and shallowness of the grooves are formed according to the strength and weakness of the pen pressure. Specifically, the part with strong pen pressure is deep, and the part with weak pen pressure is shallow. Therefore, if the depth of the groove suddenly becomes deep, it can be understood that the pen pressure should be suddenly increased for writing, and if the depth of the groove gradually becomes deep, it can be understood that the pen pressure should be gradually increased for writing. Similarly, if the depth of the groove suddenly becomes shallow, it can be understood that the pen pressure should be suddenly weakened for writing, and if the depth of the groove gradually becomes shallow, it can be understood that the pen pressure should be gradually weakened for writing.
Background Art
[0003] Regarding the plate-like body, the characters written with a brush using ink on half-sized paper are scanned, and their outlines are three-dimensionalized using 3D software, and the center line of the line width is drawn. The numerical values of the depth and shallowness of the grooves are specified from the line width of the characters. When the line width is thick, the groove is deep, and when the line width is thin, the groove is shallow. The numerical values are set in consideration of conditions such as the thickness of the material to be processed, the size of the tip of the drill of the processing machine, and forming a rising piece along the outer edge of the thin plate body.

Summary of the Invention
Problems to be Solved by the Invention
[0005] Calligraphy is technically difficult to master, and instruction in schools or extracurricular classes is particularly challenging for young children, including learning how to handle the tools. While brushwork can be learned by observing and imitating the instructor's examples, mastering the nuances of brush movement—that is, how to create rhythm and intonation—requires developing a sense of touch and acquiring the necessary technique. [Means for solving the problem]
[0006] Because it has grooves in the shape of the characters, those practicing how to write those characters can practice by moving their writing instrument, such as a brush, along the grooves. Therefore, by forming grooves in the shape of a sample character, one can practice writing that sample character and learn the feel of brushstrokes and writing techniques through physical experience.
[0007] Brush calligraphy is easy to understand, especially for learning the correct stroke order. As a supplementary element, numbers indicating the stroke order are added to the thin-frame characters to guide the user so they can move the brush without hesitation. [Effects of the Invention]
[0008] We conducted trial sessions with students from the second grade of elementary school to the first year of high school who actually attend calligraphy classes, and with students from the third grade of elementary school to the second year of high school who do not attend calligraphy classes. We compared the results of writing on paper with ink after looking at an example, and writing on paper with ink after tracing the product of the present invention. Among the students with no prior calligraphy experience, even those whose everyday language is not Japanese and who had difficulty with writing in general, such as being unsure of the stroke order, were able to improve their handwriting and understand the stroke order. Furthermore, experienced calligraphers showed significant improvements in basic calligraphy techniques such as stops, hooks, and sweeps, as well as in the shape of the characters, providing considerable proof of the product's effectiveness. [Brief explanation of the drawing]
[0009] [Figure 1] This is an isometric view of the plate-shaped material of this product. [Figure 2] This is a front view of the thin plate that is attached to the plate-shaped body of this product [Figure 1]. [Figure 3] This is a front view of the product, showing the plate-shaped body [Figure 1] and the thin plate-shaped body as a single unit. [Figure 4]Figure 3 is a front view of the "A" row, extracted by spreading the 50-sound chart outwards. [Modes for carrying out the invention]
[0010] Regarding the material of the plate-like body, any material that forms a sufficient outer surface to create grooves in the shape of letters is acceptable. Wood is preferred for its functional aspect as it is something that is touched by the hand and for its design as an interior object, but plastic, metal, or other materials are also acceptable, as long as the material is hard enough to hold the grooves.
[0011] The letter-shaped grooves formed on the plate-like body may correspond to a single character, but they can also correspond to a complete sentence. One possible form is to make the outer frame of the plate-like body a square in plan view, with the grooves formed on it representing a single character. For example, a groove corresponding to the hiragana character "あ" can be formed on a square plate-like body. Similarly, if grooves corresponding to other characters are formed on a single square plate-like body, arranging these plates with various characters formed on them vertically and horizontally will result in combinations of plates that form words, allowing for the creation of sentences or the practice of writing names. By making the plate-like body a square, it can accommodate sentences written from top to bottom, from left to right, and from right to left.
[0012] Regarding thin sheets, since they have areas that represent characters, it is sufficient for the thin sheet to have areas that represent characters when viewed from above. These character-shaped areas can be formed on the surface of the thin sheet by printing, coloring with pens or brushes, or other methods. Because these character-shaped areas can be formed by methods that result in almost no thickness, thin sheets are sheet-like materials that do not need to be thick, unlike plate-like materials which have enough thickness to form grooves. Thin sheets can be made from transparent sheets. In the case of transparent sheets, when the thin sheet is placed on top of a plate-like material, it is preferable to provide a mechanism that allows the characters to overlap so that the areas representing the characters on the plate-like material and the grooves on the plate-like material overlap, as this improves the appearance.
[0013] The reason the plate-like and thin-plate forms are separated is that, although writing characters in calligraphy is a two-dimensional expression, the pressure applied by the brush creates a sense of depth and three-dimensionality. After obtaining visual information through color and shading while the forms are assembled, the thin-plate form is removed, and the grooves of the plate-like form are traced with a dry brush to experience it tactilely. This series of actions represents the process of transforming from a two-dimensional to a three-dimensional form, deepening the understanding of the principles of calligraphy.
[0014] One such mechanism involves forming a raised section on the outer edge of the upper surface of the plate-like body, following the outer edge of the thin sheet. In other words, a recess is formed on the surface of the plate-like body, separate from the grooves for the characters, so that the thin sheet fits perfectly into it. The outer wall of this recess corresponds to the raised section. By placing the thin sheet inside the raised section, the inner wall of the raised section of the plate-like body and the outer edge of the thin sheet overlap, resulting in a character practice material in which the plate-like body and the thin sheet are integrated. Furthermore, notches are provided at the four corners of the outer edge of the thin sheet to serve as finger grips when removing the thin sheet placed on top of the plate-like body, making it easier to detach from the plate-like body. The reason for having notches at all four corners is to ensure that the thin sheet can be reached from any corner, for example, when arranging it to fit four characters on a sheet of paper, or when arranging it from the top, bottom, left, and right. Furthermore, the areas of character shapes formed on the thin plate are formed by varying shades of gray, and these shades can be obtained by any method that can create shades of gray, such as varying the number of halftone dots or the intensity of the color.
[0015] Figures 1, 2, and 3 use the hiragana character "ri" to clearly show the raised and recessed grooves, but the present invention can be applied to all 50 sounds of the Japanese syllabary, as shown in Figure 4. [Explanation of Symbols]
