PROOFREADER FOR WRITING SEQUENCE
Technical Field
[1] The present invention relates to a proofreader for writing sequence, wherein children who learn a language for the first time can learn a writing sequence exactly and easily in writing Hangul consonant, a vowel, numbers, English alphabet, Chinese characters and the like. Background Art
[2] Conventionally, a writing model for an infant or children generally has its characters printed on papers. Arrows and numbers are printed adjacent to the strokes of the characters along the order of making strokes, or the strokes of characters are sequentially printed in a stroke basis. In these examples, however, only the sequence of characters printed on papers is repeatedly written. They are a very formalized form, which does not cause an infant or children's interest. Thus, there is a problem in that it is difficult to obtain an effective learning effect because an infant or children's interest easily feel dislike.
[3] As conventional examples that are more improved, character writing is practiced using the sand writing plate or the tree plate. In these examples, convex strokes or grooves are engraved in the plates. It is thus difficult to know the order of making strokesof a letter or a start portion of the stoke at once. There is also a problem in that the plates are not suitable for a learning tool to learn the order of making strokes. Disclosure of Invention Technical Problem
[4] Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a proofreader for writing sequence, wherein the order of making strokes is indicated as colors of the strokes, which allows the order of making strokes to be seen at once, grooves are engraved from a portion where the stroke begins, which allow the start portion to be known naturally, and a portion where the stroke ends is clogged while writing is performed along grooves, thereby making the hands automatically stopped, whereby interests are induced and the order of making strokes of a character can be learnt naturally through repetitive practice. Technical Solution
[5] To accomplish the above object, a proofreader for writing sequenceof the present invention includes a character unit and acolor sequence presentation unit formed on a letter plate having a predetermined thickness. Colors of respective strokes of characters having a first color, a second color, a third color, a fourth color, etc. are formed in the character unit. Grooves are formed in the middle of each of the strokes. The color sequence presentation unit displays the order of making strokes of the characters as color separation. Furthermore, the first color, the second color, the third color, the fourth color, etc. are identical one another along each of the colors of the strokes of the character unit.

Best Mode for Carrying Out the Invention [12] The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings. [13] FIG. 1 is a plan view showing a proofreader according to an embodiment of the present invention. FIG. 2 is a lateral cross-sectional view of the proofreader taken along line A-A in FIG. 1. [14] Referring to FIGS. 1 and 2, the proofreader for writing sequence 1 according to the present invention mainly includes a letter plate 10, a character unit 20 and a color sequence presentation unit 30. [15] The letter plate 10 can be coated with a colored paperor can be formed using light materials such as colored paper, plastic and a tree plate. The character unit 20 can be formed using Formfore of 1 5mm in thickness, or a material such as non-sharp plastic.
As shown in FIG. 2, the character unit 20 can be projected from the letter plate 10 or can be engraved in the letter plate 10 so that the character unit 20 forms a cubic effect.
It is, however, to be noted that the present invention is not limited to the aforementioned materials or shapes.
Mode for the Invention [16] Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.
[17] In the character unit 20according to the present invention, strokes of characters have different colors. As shown in FIG. 1, four strokes, which form a consonant "D" being the character unit 20 formed on the letter plate 10, are divided into a first color, a second color, a third color and a fourth color according to the order of making strokes. Further, if the order of making strokes if the character unit 20 is five or more strokes, the strokes can be classified into five or more colors, if needed.
[18] For example, the first color can be selected as the red color, the second color can be selected as the blue color, the third color can be selected as the green color, and the fourth color can be selected as the black color in order to construct the order of making strokes of a Korean language consonant "D" in order of red → blue → green → black.
[19] The character unit 20 can be formed by ejecting a synthetic resin material having a predetermined color, or can be colored using the aforementioned materials or other materials. The character unit 20 can also be printed using ink having a predetermined color. The embodiment of the present invention is not limited thereto.
[20] Furthermore, the strokes of characters that form the character unit 20 have the grooves 21 at the central portion of the strokes so that the start portion and the end portion can be shown.
[21] As a more preferred embodiment, the grooves 21 make opened the start portions of the strokes, and the end portions of the strokes close the grooves. As the writing tool enters the start portion of the stroke, it naturally stops at the end portion of the stroke.
[22] As such, if the grooves are formed, when a beginner writer a letter, he cannot begin writing the letter from the end portion of the stroke. Inverse writing of the stroke can be prevented.
[23] Meanwhile, the color sequence presentation unit 30 formed on the letter plate 10 serves to prevent the order of making strokes of a letter that constitutes the character unit 20 as a color. As shown in the drawings, the order of making strokes is represented as color circles 31 and arrows 32.
[24] For example, the stroke of the consonant "D" that constitutes the character unit 20 has an order of red, blue, green and black according to the order of making strokes. The order of the color circles 31 according to the arrows 32 is red → blue → green → black, and is made coincident with the stroke color of a Korean language consonant "D".
[25] Through this construction, a beginner who learns a letter can write along the stroke order of the character unit 20 while seeing the order of the color circles 31 displayed on the color sequence presentation unit 30. Furthermore, since the beginner can write along the grooves 21 formed in the character unit 20, there is no possibility that the order of making strokes is erroneously written or the start portion and the end portion of each stroke can be confused.
[26] At this time, the color of the letter plate lOuses a color that is not used in the character unit 20. If a letter constituting the character unit 20 is a consonant, the yellow and vowel can be made different, such as the white, according to an intention of a manufacturer. Considering that children use the present invention, it is preferred that each edge portion of the letter plate 10 or the character unit 20 is curved so that it is not sharp.
[27] FIG. 3 is a plan view showing a proofreader according to another embodiment of the present invention. As in the examples shown in FIGS. 1 and 2, the character unit 20 is not limited to a simple consonant or a vowel, but can include a relatively complex character unit 20. That is, the character unit 20 may have colors of five or more strokes.
[28] Referring to FIG. 3, in the letter plate 10 in which the character unit 20 of five or more strokes is formed, the stroke of the character unit 20 can add colors (five or more colors) other than the aforementioned colors, i.e., red, blue, green and black colors. If the number of colors is too many, the order thereof may be confused. The first color group being the illustrated four colors is repeated, wherein the chromaticity of a color of the same kind as each color of the first color group is controlled.
[29] The aforementioned first color group is preferably selected as the first color of the red, the second color of the blur, the third color of the green, and the fourth color of the black.
[30] That is, as in a Korean language "D" illustrated in FIG. 3, if five or more strokes are constructed, the color sequence of a consonant "D" that is comprise of the first color groupbeing the red, blue, green and black is repeated. In this case, the remaining vowel "D" and the consonant "D" is formed of the second color group whose chromaticity is controlled like the order of blurred red → blurred blue → blurred green → blurred black. Thus, the same color kind as that of the first color group of the first four stroke is repeated.
[31] A method of fabricating it includes selecting a color that can be quite discriminated according to a common color reference table. In this case, if the character unit 20 is formed by printing color ink, a dot pattern used upon printing can be controlled. That is, if a screen having a dot pattern of 100 is used when printing color of first four strokes, a next dot pattern of the screen is set to 90, and a next dot pattern is set to 80. As such, if printing is performed as a dot pattern is reduced, a blurred color compared to an original color can be printed.
[32] In this case, the red, blue, green and black being the four stroke colors and the blurred red, blurred blue, blurred green and blurred black, which constitute the character unit 20,are only illustrative for convenience of explanation. The spirit of the present invention is not limited to the colors and number. Further, as in FIG. 4, the technical spirit of the present invention can be applied character writing of English, Chinese characters, Japanese language, and the like. More particularly, the present invention can be applied to a desired color according to a language of each country.
[33] FIGs. 4 to 6 is a plan view showing a proofreader according to further another embodiments of the present invention. FIG. 4 shows a construction in which a character unit for an English capital letter "E" and a color sequence presentation unit thereof. FIG. 5 shows a construction in which a character unit for a Chinese character "7(v" (tree) for Chinese characters and acolor sequence presentation unit thereof. FIG. 6 shows a construction in which a character unit for " ^? " (wu) among Japanese language Katagana and a color sequence presentation unit thereof.
[34] As shown in FIGs. 4 to 6, the strokes of characters, such as capital letters or small letters of the English language, the Chinese characters, and Katagana or Hiragana of the Japanese language, is formed on a letter plate as different colors. A color sequence presentation unit in which the sequence of colors identical to the order of making strokesthereof is constructed. It is thus possible to form writing sequence proofreading of all characters. Industrial Applicability
[35] As described above, according to a proofreader for writing sequence in accordance with the present invention, colors of strokes constituting a character unit are different, and the order of making strokes of a letter is displayed on a stroke sequence presentation unit. It is thus possible to view the order of making strokes at once according to a color.
[36] Further, grooves in which a start portion thereof is opened and an end portion thereof is closed in each stroke are formed. This makes clear the start and end portions of the stroke. Thus, there is an advantage in that there are no trials and mistakes in writing letters. Through these concrete manipulation activities, children can practice character writing without being feel unpleasant.
[37] Furthermore, a variety of colors introduce children's interests. Thus, children can automatically learn the order of making strokes while writing a letter along the order of making strokes using a writing tool. Accordingly, there is an effect in that learning efficiency is doubled.
