Description

[Technical field]

[0001] The present invention relates to a solid writing object such as a pencil and a set of the solid writing objects together with a case for accommodating a plurality of the solid writing objects. [Background technology]

[0002] Patent Document 1 discloses a solid writing set consisting of multiple pencils, in which patterns can be formed on the surfaces of the multiple pencils that make up the set so that they can be expressed as a unified image. Therefore, it is considered a natural technology to apply letters or the like to the surface of the pencils to indicate the lead color or product name so that the user can identify them.

[0003] [Patent Document 1] JP 2020-40396 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the solid writing set of Patent Document 1 only displays characters and patterns, so people with vision problems, such as color blindness, may not be able to recognize specific colors. This is particularly noticeable in sets where multiple colors are stored in one case.

[0005] To provide a solid writing set that enables even a visually impaired person, such as a color blind person, to easily distinguish which color is which. [Means for solving the problem]

[0006] According to one aspect of the present invention, in a solid cursive writing material having a color painted on the barrel surface indicating the lead color and a barrel color name formed on the barrel surface, if the pixel value when the color painted on the surface is converted to a grayscale is between 0 and less than 128, the pixel value when the paint color of the barrel color name is converted to a grayscale is between 128 and 255, and if the pixel value when the color painted on the surface is converted to a grayscale is between 128 and 255, the pixel value when the paint color of the barrel color name is converted to a grayscale is between 0 and less than 128. The barrel color name refers to a pattern such as letters or a picture that identifies the lead color or paint color.

[0007] It is also preferable that the difference between the pixel value obtained by gray-scale conversion of the color painted on the shaft surface and the pixel value obtained by gray-scale conversion of the character color of the shaft color name is 30 or more.

[0008] In addition, in the solid writing body set containing a plurality of the solid writing bodies, it is preferable that the outer shape of each of the solid writing bodies is substantially the same. Effect of the Invention

[0009] According to an aspect of the present invention, by setting a difference in pixel values ​​between the grayscale conversion value of the axis color and the grayscale conversion value of the character color and increasing the brightness difference, visibility is improved, making it easier for even visually impaired people such as color blindness to see the character color, and allowing them to distinguish colors in the same way as able-bodied people who are not visually impaired. [Brief description of the drawings]

[0010] [Figure 1] 1 is a solid writing instrument according to an embodiment of the present invention. [Diagram 2] 1 is a set of solid writing implements according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Corresponding components throughout the drawings are designated by common reference numerals.

[0012] FIG. 1 shows a solid writing instrument according to an embodiment of the present invention, where FIG. 1(a) is a left side view, FIG. 1(b) is a front view, and FIG. 1(c) is a right side view.

[0013] The solid writing object of the embodiment is a pencil 1 that houses a writing lead 5 in its shaft. A shaft surface 2 of the pencil 1 is painted in substantially the same color as the writing lead 5. In addition, characters 3 indicating the lead color and the name of the barrel color of the writing lead 5 are formed in hiragana on the barrel surface 2. In addition to the characters 3, a pattern 4 is formed that indicates an icon that evokes the lead color.

[0014] The color in FIG. 1 is a grayscale conversion of the red color of the writing lead 5, and is a state that can actually be seen by a person with color blindness. The axis color of the character 3, "red," is painted red, and the pixel value of the grayscale conversion of the red color in this embodiment is 85, which is within the range of gradations from 0 to less than 128. Therefore, by setting the grayscale conversion of the character color of character 3, "red," to 128 to 255, the content of character 3 can be easily recognized. In this embodiment, the pixel value of the grayscale conversion of pattern 4 is 250, which is close to white.

[0015] Grayscale conversion is the conversion of a color image into a grayscale image. After conversion, the pixel values ​​are quantified in 256 gradations, with 0 being black and 255 being white, and the values ​​between them are subdivided grays into which the color has been converted. Scale conversion converts the color information of the axis surface into a luminance value, thereby converting the color image into a grayscale image. For example, scale conversion may extract one RGB element from each pixel and convert it into a corresponding luminance value. The luminance value is a numerical value indicating the brightness of the pixel, and is an example of a pixel value. Alternatively, the conversion may calculate the luminance value using the NTSC-based weighted average method or simple average method, etc.

[0016] Alternatively, the gradation value may be a percentage of the brightness of the color, in which case a value between 0 and 128 is less than 50%, and a value between 128 and 255 is 50% or greater.

[0017] In the embodiment, the grayscale was determined by taking a photograph of the shaft surface 2 of the pencil 1, which is the actual product, with a smartphone (iPhone 12: registered trademark), and measuring the grayscale of the target area from the obtained image using image processing software. ImageJ 1.54f, an image processing software, was used to measure the grayscale.

[0018] The pattern 4 is formed with a picture of an apple, which is associated with the color red, and the color of this pattern is preferably the same grayscale converted pixel value as the characters 3. In addition, by making the difference in pixel value between the shaft surface 2 and the characters 3 and pattern 4 30 or more, there is a clear brightness difference, and the visibility of the characters 3 and pattern 4 can be improved.

[0019] The coating on the shaft surface 2 is preferably a one-component self-crosslinking polyurethane dispersion, which is an aqueous dispersion of polyurethane elastomer with silanol groups as substituents on the surface of a colored coating and has a glass transition temperature (Tg) of less than 70°C, applied to the surface of the pencil shaft, and the water in the applied coating is then evaporated to obtain a coating film, which gives the pencil good adhesion to the coating surface and an excellent rubbery feel.

[0020] As a specific example of the coating, a colorless paint is formed with a composition consisting of 89.5 parts by weight of one-component self-crosslinking polyurethane dispersion (WS-6021, Mitsui Takeda Chemical) as a resin, 7.2 parts by weight of polyoxyethylene urethane modified ether (Nippon Paint) as a thickener, 2.4 parts by weight of silica C type (Nippon Paint) as a matting agent, and 0.9 parts by weight of silica / mineral oil-based defoamer (Nippon Paint) as a defoamer. The glass transition temperature (Tg) of this paint is -60℃ and 40℃, and the viscosity is approximately 40,000mPa·sec.

[0021] 2 is a plan view of a pencil set 10 that contains multiple solid writing objects, i.e., pencils 1. The pencil set 10 contains 12 pencils 1 with different colors of writing leads 5 in an inner gasket 11, and each of the multiple pencils 1 has a different writing lead color and a corresponding barrel color painted on the barrel surface 2.

[0022] The inner case 11 is a container made of synthetic resin that contains 10% or more of marine plastic by weight, and has a recess on its surface so that multiple pencils 1 can be lined up in the same direction. Also, case letters 12 and case patterns 13 similar to the letters 3 and patterns 4 of the pencil 1 are formed on the surface of the inner case 11 so that pencils of different colors can be easily stored in the same direction of the recess.

[0023] The color of the inner case 11 in Fig. 2 is a grayscale conversion of a light gray color, and is in a state that can actually be seen by a person with color blindness. In this embodiment, the pixel value of the grayscale conversion of the light gray color is 220, which is within the range of gradation from 128 to 255. The grayscale conversion of the case characters 12 and the case pattern 13 has a color range of 0 to less than 128. In this embodiment, the pixel value of the grayscale conversion of the case characters 12 and the case pattern 13 is 3, which is close to black.

[0024] In addition, the color of the letters 3 and patterns 4 of each pencil 1 varies depending on the writing lead 5 and the coating color of the barrel surface 2. For example, the pixel values ​​of the grayscale conversion of the coating color of the barrel surface 2 for "black," "purple," "blue," "green," "light blue," "light green," "orange," "pink," "red," and "brown" are in the range of gradations from 0 to 128, and therefore have character colors close to white. Meanwhile, the pixel values ​​of the grayscale conversion of the coating color of the barrel surface 2 for "yellow" and "light orange" are in the range of gradations from 128 to 255, and therefore have character colors close to black.
