Description

Technical Field

[0001] The present invention relates to a sheet for memorization learning, a marker set for memorization learning, and a pen sheet set for memorization learning, which can superimpose a colored transparent sheet having translucency presenting a specific color on a portion where characters of a printed matter are colored with a marker pen of a specific color or a portion where characters or the like are written with a writing pen of a specific color on the printed matter, so that the characters in the colored portion cannot be seen, or only the characters written in a specific color cannot be seen.

Background Art

[0002] Conventionally, a colored transparent sheet having translucency presenting a specific color (hereinafter simply referred to as "sheet") is superimposed on a portion colored with a marker pen (hereinafter simply referred to as "marker") or a portion where characters or the like are written with a writing pen (hereinafter simply referred to as "pen") to conceal the colored portion or the written characters so that they cannot be visually recognized. Thus, a marker set for memorization that can be used for memorization work during learning, for example, has been proposed. Here, when performing learning such as memorization work using the colored transparent sheet as described above, there are the following two modes.

[0003] In the former mode, a portion such as characters to be memorized with a marker that appears black or extremely dark when viewed through a sheet of a specific color is marked. The marked portion is visually recognized while being emphasized in the ink color of the marker when viewed as it is, but when the sheet is superimposed, the entire marked portion is concealed as if it were painted black and cannot be visually recognized. The user performs memorization learning by remembering or speculating on the concealed characters or the like.

[0004] As a latter aspect, as disclosed in Patent Document 1 below, there is an aspect of using a pen of the same color as the color of the sheet to write characters such as content or hints that the user wants to memorize together between the lines of text or outside the columns of a printed matter. When the sheets are stacked, the written characters etc. are hidden in the color of the sheet, so the user performs memorization learning by remembering or speculating on the hidden characters etc.

[0005] In recent years, among users who perform memorization learning as described above, there has been a strong tendency not to use only one of the above aspects, but to use both aspects in combination. In other words, on the same target surface such as the same textbook or notebook page, the two aspects are used separately, and there is a stronger desire to further improve learning efficiency.

[0006] The memorization pen set disclosed in Patent Document 1 has the complexity that users who want to use both of the above aspects must possess a plurality of at least one of the sheets or pens. Therefore, in order to make it easier for users to handle the memorization pen set during memorization learning, as disclosed in Patent Document 2 below, a memorization pen and a memorization pen set are provided that have a marker that appears black when viewed through the sheet and a pen of a color that cannot be read out by being blended into the color of the sheet on a single shaft body.

Patent Document 1

Patent Document 2

[0007] However, since conventional memorization pen sets are basically used in combination with a single-color sheet, a marker that appears black when viewed through the sheet, and a pen in a color that cannot be read because it blends in with the color of the sheet, the markings and characters that can be hidden with a specific color sheet are limited. Therefore, for example, when there are many words to be memorized in a textbook passage as shown in Fig. 1, if all the words to be memorized are marked in a specific color, the hidden words will be continuous when the sheets are stacked, and the passage cannot be read as a text in the first place, so there is a problem that effective memorization learning cannot be carried out.

[0008] Also, for example, in the memorization learning of the periodic table of chemistry as shown in Fig. 2, when both the element symbols and element names are marked, both will be hidden when the sheets are stacked, and there is also a problem that the teaching material cannot be formed in the first place. On the other hand, if only the element names are marked as shown in Fig. 3, the memorization method of "What is the element name of the element symbol He?" is possible, but the reverse memorization method of "What is the element symbol of helium?" cannot be done, and there is a problem that the teaching material can only be used for one-way memorization learning.

[0009] Also, for example, in a teaching material for English reading comprehension as shown in Fig. 4, even if the Japanese translation is handwritten in an orange pen under the English text for memorization, all the Japanese translations will be hidden when a red sheet is stacked, so there is a problem that it is too difficult to memorize. In this case, if symbols such as "S", "V", "O" representing important words and syntactic structures are filled in different colors so that only the Japanese translations other than these are hidden when the sheets are stacked, step-by-step memorization learning will be possible, but this cannot be done with a single red sheet.

[0010] When the words to be memorized are consecutive or when memorizing the periodic table, by using two-color markers to color-code the marking colors of arbitrary words and replacing them with two sheets that can conceal each color, it is possible to select the areas to be concealed for each ink color. When memorizing English word textbooks, by replacing and using two sheets, one that obscures only one color of the characters written with a two-color pen and another that obscures only the other color, it is possible to select the characters to be concealed, enabling step-by-step or two-way memorization learning. Therefore, there are also users who practice a memorization learning method that actually combines two-color markers or pens with two sheets of corresponding colors.

[0011] On the other hand, students, who are the main users of such memorization learning tools, mainly use them for memorization learning of English words, classical Chinese words, terms in history textbooks, etc. while on the train during commuting. However, since learning is done in a limited space without a desk on the train, it is not easy to spread textbooks etc. on one's lap, hold a marker or pen in one hand, and hold two sheets with the other hand. It is even more difficult to do so while standing. Also, there is a problem that when switching and using the two sheets, the area to be concealed is inevitably visible for a moment. Therefore, the memorization learning method using two sheets as described above has been difficult.

[0012] In addition, for conventional memorization learning marker sheet sets, it was common for the sheet color to be red or green and the marker color to be pink or light blue, and for memorization learning pen sets, the sheet color to be red and the pen color to be orange. However, in recent years, the learning content has become more advanced and complex, and there is a demand for marker sheet sets and pen sheet sets with more color combinations. Also, the variety of the colors of the markers and pens themselves has increased, and the need for memorization learning sheets that can accommodate color combinations according to the preferences of users, mainly junior and senior high school students, has been increasing.

Problems to be Solved by the Invention

[0013] The present invention was created to solve the problems of the prior art as described above and to meet new needs. It is an effective rote learning method that combines two-color sheets with two-color markers or pens, which can be easily carried out even in trains during commuting or going to school, contributing to the improvement of learning efficiency. The present invention aims to provide a rote learning sheet, a rote learning marker sheet set, and a rote learning pen sheet set that can accommodate various combinations of sheets, markers, and pens according to the needs and preferences of users.

Means for Solving the Problems

[0014] In order to solve the above problems, the inventor of the present application first integrated two two-color sheets into one sheet. That is, the rote learning sheet according to claim 1 is a single colored transparent sheet composed of two color regions: a first color region colored with a first specific color having translucency and a second color region colored with a second specific color.

[0015] By making the upper half and the lower half of a single sheet different specific colors, the user only needs to carry one sheet, and can easily handle the two-color sheet with one hand. Therefore, there is no need to purchase sheets of different colors, and the risk of loss can be reduced. Then, by using a marker or pen that uses ink of a color hidden by each specific color, the user only needs to hold a sheet and a marker or pen in each hand. Therefore, an effective rote learning method can be carried out even in a limited space such as in a train. Also, when properly using the specific colors of the sheet, it is only necessary to slide the sheet on the page of a textbook or the like. Thus, it is possible to prevent the hidden parts from being visible when switching between two sheets, or the two sheets accidentally overlapping and becoming black, making the text and the like invisible. Also, from the manufacturer's side, it is not necessary to manufacture two-color sheets separately and hold inventory, thus reducing costs.

[0016] On the one hand, the color of a conventional general mnemonic learning sheet was red or green. This is because red and green are respectively complementary to the pink color (bright red) and light blue color (bright blue) of commonly used fluorescent markers. When viewed through the sheet, the areas marked with each marker appear black, and characters and the like are effectively hidden. However, regarding the colors of the first color region and the second color region of the sheet that hide the areas colored with a marker of a specific color to make the characters and the like in that area illegible, or do not hide them and make them legible, various color combinations are possible.

[0017] "Complementary color" refers to the color located on the opposite side of a specific color in a color wheel (a circular arrangement of the light source colors, which are the colors of the light source, continuously arranged according to the difference in the wavelength of light). Figure 5 shows a typical 12-color wheel, which is a representative color wheel. The 12 colors of yellow Y (Yellow), yellow-green YG (Yellow-Green), green G (Green), blue-green BG (Blue-Green), greenish blue GB (Green-Blue), blue B (Blue), blue-violet BP (Blue-Purple), purple P (Purple), red-violet RP (Red-Purple), red R (Red), red-orange RO (Red-Orange), and yellow-orange YO (Yellow-Orange) are arranged in a circular shape. Also, the colors located on both adjacent or nearby positions to a specific color on the 12-color wheel are called "analogous colors".

[0018] For example, on a 12-color wheel, the complementary color of red R is blue-green BG. When looking through a red R sheet, not only does blue-green BG appear almost black, but also the areas colored with markers of its analogous colors, green G, greenish blue GB, and blue B, appear black or extremely dark, and the characters printed in black within those areas are hidden, making it difficult to read. Therefore, light blue LB (light Blue), which is a high-brightness blue B, appears almost black through the red R sheet, and the marked characters and the like are hidden. Similarly, when looking through a green G sheet, not only does the complementary color, red-violet RP, appear almost black, but also its analogous colors, orange RO with a red tint, red R, purple P, and blue-violet BP, become difficult to read. Therefore, pink LR (light red with high brightness), which is a high-brightness red R, appears almost black through the green G sheet, and the marked characters and the like are hidden. However, the degree of hiding varies depending on the brightness and saturation of each color.

[0019] Next, the sheet for latent learning according to claim 2 is characterized in that the first specific color and the second specific color are a combination of two colors among the three primary colors of object color (cyan, yellow, magenta).

[0020] The hiding effect of other colors by the color of the sheet can also be explained by the color mixing of the three primary colors of object color (cyan C, yellow Y, magenta M). As shown in FIG. 2, when cyan C 100% and yellow Y 100% are mixed, green G is obtained; when yellow Y 100% and magenta M 100% are mixed, red R is obtained; when magenta M 100% and cyan C 100% are mixed, blue B is obtained. All colors can be represented by the ratio of the color mixing of the three primary colors of object color. Note that the color mixing of any two of the three primary colors of object color results in a lower brightness than either of the original two colors, and the color mixing of all three colors results in black. Also, when cyan C, yellow Y, and magenta M are described below, unless otherwise specified, all three colors refer to 100% colors.

[0021] "Object color" refers to the color of the object itself that can be recognized when light is applied to the object. There are a surface color that can be seen when light is reflected from the surface of the object and a transmission color that can be seen through colored glass or the like. The color of the marker seen through the sheet is the transmission color. When the color of the marker is the wavelength absorbed by the color of the sheet when passing through the sheet, it appears as a darker color depending on the degree of absorption (subtractive color mixing). And the effect of making the color of the marker closer to black is maximized when the colors of the sheet and the marker are complementary colors.

[0022] According to this subtractive color mixing, the red R of the red sheet is the color mixture of magenta M and yellow Y (M + Y), and the light blue LB (high-brightness blue B) of the light blue marker is the color mixture of cyan C and magenta M (C + M). Therefore, when the two are overlapped, the three colors of M + Y + C + M (= C2MY) are mixed to become black, and the characters at the marked locations are hidden and unreadable. Similarly, the green G of the green sheet is the color mixture of yellow Y and cyan C (Y + C), and the pink color LR of the pink marker is the color mixture of magenta M and yellow Y (M + Y). Therefore, when the two are overlapped, the three colors of Y + C + M + Y (= CM2Y) are mixed to become black, and again the characters at the marked locations are hidden and unreadable. On the other hand, for the locations not colored with the marker or the locations colored with a marker of a color with a wavelength that is less absorbed by the color of the sheet, since the degree of subtractive color mixing is also small, the characters printed in black can be read.

[0023] Next, the invention according to claim 3 is the sheet for cryptomnesia learning according to claim 1, wherein the first specific color and the second specific color are any two colors selected from combinations of any two colors of the three primary colors of object color (cyan, yellow, magenta) mixed in an arbitrary ratio.

[0024] Further, the invention according to claim 4 is the sheet for cryptomnesia learning according to claim 1, wherein the first specific color and the second specific color are a combination of any two colors selected from a total of six colors including the three primary colors of object color (cyan, yellow, magenta) and specific color mixtures formed by mixing any two of the three primary colors in an arbitrary ratio.

[0025] The invention according to claim 5 is the sheet for rote learning described in claim 3, characterized in that the first specific color is green and the second specific color is red. If the colors of the sheet are a combination of two colors, green G and red R, these colors are in a complementary color relationship with each other, and moreover, it becomes possible to apply markers of light blue LB and pink LR, which are already widely spread and used frequently, for rote learning immediately.

[0026] Furthermore, if it is possible to provide a sheet that includes, in a combination of two colors, not only green G and red R but also complementary colors and similar colors of yellow Y and orange O (orange), which are similarly widely and commonly used marker colors, the spread of the sheet can be promoted. Specifically, blue-violet BP, which is the complementary color of yellow Y, or blue B and purple P, which are similar colors thereof, or blue B, which is the complementary color of yellowish orange YO (bright orange), or greenish blue GB and blue-violet BP, which are similar colors thereof, can also be applied as elements of the combination of two colors of the sheet.

[0027] On the other hand, various color combinations are also possible for the colors of the first color area and the second color area of the sheet that hide the characters etc. written with a pen of a specific color so that they cannot be read, or that make them readable without hiding.

[0028] The invention according to claim 6 is the sheet for rote learning described in claim 1, characterized in that the second specific color is a similar color with a lower lightness than the first specific color.

[0029] When two colors of the same color with only different lightness are overlaid, naturally, the characters etc. drawn in the color with a higher lightness, that is, a brighter color, will be hidden and become invisible in the color with a lower lightness, that is, a darker color. On the other hand, in the case of two different colors, if they are chromatic colors, since the wavelengths of the colors are different, even if there is a difference in lightness, it is not always the case that the color with a higher lightness will be hidden and become invisible in the color with a lower lightness, and there are cases where it is still readable even if the color tone changes. However, if they are similar colors, since the wavelengths of the colors are approximated, when two similar colors with a difference in lightness are overlaid, they will be completely invisible to the naked eye or at least difficult to read.

[0030] Therefore, when covered with the memorization learning sheet according to claim 6, characters written with a pen in a similar color whose ink color has a higher lightness than the first specific color will become completely invisible or at least difficult to read when covered with either the first color area or the second color area. Also, characters written with a pen in an ink of a similar color whose lightness is between the first specific color and the second specific color can be read when covered with the first color area with a higher lightness, but will become completely invisible or difficult to read when covered with the second color area with a lower lightness.

[0031] The invention according to claim 7 is the memorization learning sheet according to claim 6, wherein the first specific color is orange - red and the second specific color is red. By utilizing the hiding relationship based on the lightness difference between similar colors, characters written with pens in inks of similar colors with different lightness are selectively hidden / readable by appropriately switching and covering with two color areas on a single sheet.

[0032] Orange - red RO is a similar color to red R and has a higher lightness than red R. Here, for example, when covering both characters written with a pen (the first pen) in an ink of yellow - orange YO (generally known as "orange" as the color name of a marker or pen) with a higher lightness than orange - red RO and characters written with a pen (the second pen) in an ink of pink (high - lightness red R) with a lower lightness than orange - red RO with the first color area of orange - red RO, the characters written with yellow - orange YO with a higher lightness than orange - red RO are hidden, but the characters written with pink (low - lightness red R) are readable. On the other hand, when covering with the second color area of red R, both the characters written with yellow - orange YO, which is a similar color to red R and has a higher lightness, and the characters written with pink (high - lightness red R) are hidden.

[0033] The colors of the two color areas of the sheet are not particularly limited to orange-red RO with a reddish tint and red R. As long as the lightness of the colors of the first pen and the second pen is in the order of "the color of the first pen > the first specific color > the color of the second pen > the second specific color", it is not particularly limited as long as this relationship is satisfied. Here, in the invention according to claim 7, the reason for setting the first specific color as orange-red RO and the second specific color as red R is that considering the following tendency of the actual use of stationery for rote learning by examinees such as junior and senior high school students who are the main users, such a combination of colors is considered to be suitable.

[0034] That is, according to the questionnaire survey "What are the key points when memorizing? Thorough introduction of study methods and stationery!" (Implementation period: July 3, 2019 to August 16, 2019, Target respondents: current junior and senior high school students or school dropouts under 20 years old, Number of respondents: 313, URL https: / / juken-mikata.net / topics / memorization.html) conducted by the entrance exam support media "Juken no Mikata" for high school students, in response to the question "Please tell me what you use most often when studying memorization subjects", the answer "green check pen (marker) and red sheet" was 8.95%, while the answer "orange pen and red sheet" was 44.41%. In rote learning using a set of sheet and pen, the combination of a red sheet and an orange (yellowish orange YO) pen is overwhelmingly preferred.

[0035] From the results of this questionnaire survey, it was found that examinees and the like repeated rote learning by, for example, filling in the answer column for the correct answer to the question with an orange pen, hiding this with a red sheet, answering the question, and then checking the correct answer, or by repeatedly writing important phrases and the like in an orange pen in a summary note they made themselves and covering the page with a red sheet to hide the important phrases and the like and then recalling them. Therefore, in the rote learning sheet according to claim 7, by setting the first specific color as orange-red RO and the second specific color as red R, it corresponds to the orange pen preferred by examinees and the generally popular pink pen.

[0036] Next, a marker set for memorization learning that combines two-color markers on a memorization learning sheet and a pen set for memorization learning that combines two-color pens will be described.

[0037] The invention according to claim 8 is a marker sheet set for memorization learning, which is a single colored transparent sheet composed of two color areas: a first color area colored with a first specific color having translucency and a second color area colored with a second specific color. The memorization learning sheet, a first marker, and a second marker, wherein the first specific color is cyan among the three primary colors of object colors (cyan, yellow, magenta), the second specific color is magenta, the color of the ink of the first marker is a mixed color of yellow and magenta, and the color of the ink of the second marker is a mixed color of cyan and yellow.

[0038] Here, yellow Y or a similar color is not adopted as the specific color of the sheet because if either the color of the sheet or the marker is a single yellow Y or a similar color, depending on the lightness of the other color, the lightness of the marked area cannot be sufficiently reduced by subtractive color mixing, that is, the hiding effect may be insufficient.

[0039] For example, in the combination of a sheet of blue B, which is a similar color to cyan C, and a yellow Y marker, blue B is a mixed color of cyan C and magenta M (C + M). When the yellow Y marker is covered with this, C + M + Y (= CMY) results in a state where three colors are mixed. However, since single yellow Y itself is a color with extremely high lightness (lightness of 10% in grayscale), when mixed with blue B (the same 91%) with a relatively large lightness difference, it does not become a sufficiently dark color, and characters etc. can be read, resulting in an insufficient hiding effect. On the other hand, if the density of blue B is increased too much, the marked characters themselves when not covered by the sheet become difficult to read.

[0040] On the other hand, in the combination of the blue B sheet and the reddish orange RO marker, since the blue B sheet, which is a mixture of cyan C and magenta M (C+M), covers the reddish orange RO marker, which is a mixture of yellow Y and magenta M (M+Y), a state where C+M+M+Y (=C2MY) and three colors are mixed is obtained. Moreover, since the weight of magenta M with a relatively high density (the same 68%) is high, a concealing effect such that characters and the like at the marking position are illegible can be obtained. Also, in this case, even if the density of the color of the sheet (C+M) is slightly lowered, since magenta M, which is a component of the sheet color, and magenta M, which is a component of the marker color, are mixed doubly, a concealing effect can be obtained.

[0041] From the above, although it depends on the mixing ratio, if either the sheet or the marker has a single color of yellow Y, the concealing power cannot be exerted regardless of the color of the other party, and in many cases, the concealing power is insufficient even for yellowish green YG or yellowish orange YO, which are similar colors to yellow Y. Also, even if the color of the sheet is a single yellow Y, although a concealing effect can be expected if the brightness of the color of the marker is sufficiently low, in that case, there is a problem that characters and the like marked are difficult to read with the marker color itself. Therefore, a single yellow Y is not suitable as the color of the sheet.

[0042] Next, the invention according to claim 9 is a marker sheet set for rote learning, comprising a single colored transparent sheet composed of two color areas, namely a first color area colored with a first specific color having translucency and a second color area colored with a second specific color. It also includes a first marker and a second marker. The first specific color and the second specific color are a combination of any two colors among the three primary colors of object colors (cyan, yellow, magenta), which are a specific mixed color formed by mixing two of them in an arbitrary ratio. When the combination of the first specific color and the second specific color is a combination of a mixed color of cyan and yellow and a mixed color of yellow and magenta, the colors of the inks of the first marker and the second marker are a combination of a color containing at least magenta and a color containing at least cyan. When the combination of the first specific color and the second specific color is a combination of a mixed color of yellow and magenta and a mixed color of magenta and cyan, the colors of the inks of the first marker and the second marker are a combination of a color containing at least cyan and a color containing at least yellow. When the combination of the first specific color and the second specific color is a combination of a mixed color of magenta and cyan and a mixed color of cyan and yellow, the colors of the inks of the first marker and the second marker are a combination of a color containing at least yellow and a color containing at least magenta, which is characterized by this.

[0043] In the marker sheet set for rote learning according to claim 9, since the color of the sheet is set to any two colors among the specific mixed colors (CY, YM, MC) formed by mixing any two of the three colors cyan C, yellow Y, and magenta M in an arbitrary ratio, as a result, all colors other than black and muddy colors obtained by mixing all three primary colors of object colors cyan C, yellow Y, and magenta M are applicable. However, as described above, when a mixed color with high brightness obtained by mixing yellow Y, which has extremely high brightness specific to the color, with other colors is used for the sheet or the marker, the concealing effect of the marked area is likely to be insufficient regardless of the color of the marker or sheet to be combined. Therefore, it is desirable that the difference in mutual density when the colors of the marker and the sheet to be combined are grayscaled is at least 30% or more, and preferably 50% or more.

[0044] The invention according to claim 10 is the marker sheet set for rote learning according to claim 9, wherein the first specific color is green, the second specific color is red, the color of the ink of the first marker is pink, and the color of the ink of the second marker is light blue.

[0045] Next, the invention according to claim 11 is a pen set for rote learning, comprising a rote learning sheet which is a single colored transparent sheet composed of two color regions, namely, a first color region colored with a first specific color having translucency and a second color region colored with a second specific color, a first pen, and a second pen. The second specific color is a similar color having a lower brightness than the first specific color, the color of the ink of the first pen is a similar color having a higher brightness than the first specific color, and the color of the ink of the second pen is a similar color having a lower brightness than the first specific color and a higher brightness than the second specific color.

[0046] Further, the invention according to claim 12 is the pen set for rote learning according to claim 11, wherein the first specific color is orange with a red tint, the second specific color is red, the color of the ink of the first pen is orange with a yellow tint, and the ink of the second pen is pink.

[0047] As described above, the colors of the two color regions of the sheet may be analogous to each other, and the lightness of these colors and the colors of the first pen and the second pen may be in the order of "color of the first pen > first specific color > color of the second pen > second specific color". However, if the lightness difference between the color of the first pen and the first specific color is too small, when covering the first color region of the sheet, characters written with the first pen may not be hidden and may be readable. Also, if the lightness difference between the color of the first specific color and the color of the second pen is too small, when covering with the first color region, characters written with the second pen may become unreadable. Similarly, if the lightness difference between the color of the second pen and the second specific color is too small, when covering the second color region, characters written with the second pen may be readable. Also, although they are analogous colors to each other, the lightness, that is, the density when grayscale-converted, is different depending on the component ratios of the three primary colors of the object color that makes up each color. Therefore, the lightness differences of the four colors of the color of the first pen, the first specific color, the color of the second pen, and the second specific color applicable to the present invention vary depending on the color.

[0048] Here, it is desirable that the lightness difference between the color of the first pen and the first specific color is at least 5% or more, and preferably 10% or more. Also, it is desirable that the lightness difference between the first specific color and the color of the second pen is 5% or more, and preferably 10% or more. On the other hand, it is desirable that the lightness difference between the color of the second pen and the second specific color is 5% or more, and preferably 10% or more.

[0049] For example, when the color of the first pen is a bright orange marker color (yellowish orange, color components are cyan 0: magenta 50: yellow 100, density 43%) that is generally popular, and the first specific color is a dark orange (reddish orange, color components are cyan 0: magenta 67: yellow 100, density 54%), the lightness difference is 11%, and characters written with the first pen are hidden by the first color region and become unreadable.

[0050] Similarly, if the color of the second pen is set to a popular pink marker color (bright red, color components are cyan 0: magenta 83: yellow 0, density 61%), and the second specific color is set to a common red (cyan 0: magenta 100: yellow 100, density 68%), the brightness difference is 7%. However, since both are similar colors with low brightness, the characters written with the second pen are hidden by the second color area and become illegible. On the other hand, the brightness difference between the pink characters written with the second pen and the dark orange of the first color area is also 7%. Similar colors with lower brightness, such as pink, can still be legible even when the density increases.

[0051] Incidentally, the shape of the sheet according to the present invention, the range (arrangement) of the first and second color areas, and the form of the boundary line of the areas are not particularly limited. However, it is preferable that the shape of the sheet is a horizontally long or vertically long rectangle, the range of the color area is divided into upper and lower halves in both the horizontally long and vertically long cases, and the boundary line is a horizontal straight line. However, the boundary line may also be a gradation in which the two color areas are gradually color-separated.

[0052] The reason for making the sheet horizontally long or vertically long is in consideration of the specifications of textbooks, notebooks, etc. used for rote learning, the text, illustrations, and their layouts to be memorized. Many general textbooks used in junior high and high schools are B5 size. However, textbooks on history, science, English, etc. generally have horizontally written text, and there are also pages with illustrations or tables laid out in blocks on either the left or right side of the page. On the other hand, textbooks on Japanese, classical literature, Chinese, etc. have vertically written text, and there are also pages with annotation columns or illustrations laid out in vertical strips or blocks on either the left or right side of the page.

[0053] When the width of the horizontally long sheet is made to correspond to the page width of a B5-sized textbook, the upper and lower color areas will be divided horizontally into slender shapes (narrow division). Therefore, in textbooks on history, science, English, etc., the horizontally long sheet can be directly overlapped on the page to cover the entire lines of the horizontally written long layout text. Also, in textbooks on Japanese, classical literature, Chinese, etc., by rotating the horizontally long sheet by 90°, it is possible to cover the entire lines of the vertically written long layout text and the vertical strip-shaped annotation columns provided at the edges of the page.

[0054] On the other hand, in the case of a vertically long sheet, since the specific colors at the top and bottom are each in a shape close to a square (thus divided), it can cover a block-shaped target range with a certain size both vertically and horizontally, such as a plate (map, graph, chronology, etc.) or a table. Also, in the study of languages such as Japanese, classical Chinese, and Chinese classics, it is common for users such as students to divide the horizontally oriented notes into upper and lower sections, and make their own study notes by writing the main text and translation in the upper section and annotations, important matters, hints, etc. in the lower section. In such cases, if a vertically long sheet (thus divided) is used, the upper and lower sections can be covered together in different colors. Therefore, after appropriately writing the translation in the upper section and annotations, important matters, hints, etc. in the lower section with different pens, by sliding the sheet to the left, a memorization learning method can be achieved where the hidden characters can be sequentially made visible.

[0055] Also, as a sheet for a memorization learning pen set, that is, when memorization learning is carried out by hiding characters written with a pen, for example, after writing the correct answer with a first pen next to the question text on the note, and adding and writing important matters (hints) for deriving the correct answer with a second pen, when covering with the upper half (the first color area) of the sheet, the correct answer is hidden and only the hints are visible, and learning can be carried out to reach the correct answer from the hints. And at the stage when the hints can be recalled from the question text, when the sheet is rotated and covered with the lower half (the second color area), both the correct answer and the hints are hidden and only the question text is visible, and it is possible to confirm the degree of fixation of the memorization of important matters by whether the question can be solved without hints, enabling a more advanced two-stage memorization learning.

[0056] Furthermore, in subjects such as English, Japanese, classical literature, and Chinese classics, the frequency of writing characters with a pen in textbooks and notebooks during learning is high, and it is common for these teaching materials to have long texts printed from end to end on both horizontal and vertical pages. When covering teaching materials with a horizontally long sheet (narrow split), horizontally for English and vertically for Japanese, classical literature, and Chinese classics, long texts can be covered several lines at a time, and by sliding the sheet, the text can be sequentially revealed line by line along the boundary line between the two color areas, and the hidden characters written with a pen below or to the left of the text can be made visible.

[0057] The invention according to claim 13 is a sheet for rote learning, which is a single colored transparent sheet composed of three color areas: a first color area colored with a first specific color having translucency, a second color area colored with a second specific color, and a third color area colored with a third specific color.

[0058] By providing three color areas on the sheet, when used as a sheet for a rote learning marker set, characters marked with corresponding three-color markers can be hidden, so the number of attribute groups of items to be memorized can be increased, and more advanced rote learning can be achieved with a single sheet.

[0059] Finally, the invention according to claim 14 is the sheet for rote learning according to claim 13, wherein the first specific color is green G, the second specific color is red R, and the third specific color is orange O.

[0060] According to such a configuration, by combining two-color markers and two-color pens, a single sheet can be used as both a marker set and a pen set for rote learning. The hiding of both marked characters and characters written with a pen can be switched at any time, improving the efficiency of rote learning and also enhancing the operability and portability as a set.

[0061] Incidentally, two single-color markers or pens may be used in pairs, but if a two-color marker or pen is configured by accommodating two two-color marker chips or two two-color pen chips in a single shaft body and integrating them, the items to be carried can be reduced and the risk of loss can be minimized. In particular, the burden on the user when studying on a train or the like can be reduced.

Advantages of the Invention

[0062] When using the memorization learning sheet according to the present invention, the memorization target portions of the teaching material can be classified into two types and marked with two-color markers, and these two types of memorization target portions can be alternately concealed with a two-color sheet in each color and its complementary color system. Therefore, a memorization method divided into two steps is possible even for teaching materials with a large number of memorization target portions. In addition, since a mutual memorization method is possible for the relationship between the two types of memorization targets, the efficiency of memorization learning is improved. Furthermore, by sliding the two-color boundary line of the sheet along the memorization target portion of the teaching material for each row, the concealed characters and the like can be made visible for each row. Therefore, the two types of memorization target portions color-coded with two-color markers can be sequentially confirmed, and the effect is that more complex and advanced memorization learning can be efficiently promoted without having to turn the sheet each time.

[0063] Also, when using the memorization learning pen sheet according to the present invention, important items such as correct answers and hints can be color-coded and entered in the memorization target portions of the teaching material and learning notes with two-color pens, and these two types of entered items can be gradually concealed with a two-color sheet in each color and different brightness. As a result, a learning method divided into two steps, such as learning with only hints and learning without hints, becomes possible, and more advanced and efficient learning becomes possible. Furthermore, by sliding the two-color boundary line of the sheet along the memorization target portion of the teaching material for each row, the concealed characters and the like can be made visible for each row. Therefore, the two types of entered items color-coded with two-color pens can be sequentially confirmed, and the effect is that more complex and advanced learning can be efficiently promoted without having to turn the sheet each time.

[0064] Furthermore, since both the marker sheet set and the pen sheet set for rote learning integrate two-color sheets, there is no need to switch between two sheets according to the colors of the markers or pens, making it easier to perform rote learning in limited spaces without desks, such as on a train. Also, by making the two-color sheets into two sheets, one horizontally long (narrow division) and one vertically long (square division), the entire row can be covered regardless of whether the textbook or notebook is written horizontally or vertically with four lines, and the divided sheets can also cover block-shaped memorization target areas such as diagrams and tables. Therefore, a usage method according to the specifications of the teaching materials and the layout of the memorization target areas becomes possible, and the efficiency of rote learning can be improved accordingly.

Best Mode for Carrying Out the Invention

[0066] (First Embodiment) Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 7 is a schematic diagram showing a two-color marker 1, a horizontally long sheet 2, and a vertically long sheet 3 that constitute the marker sheet set for memorization learning according to the first embodiment of the present invention.

[0067] The two-color marker 1 includes a pink ink storage part LR having a marker chip LR1 that can be marked with pink ink in a strip shape, and a flat shaft body 10 that houses a blue ink storage part B having a marker chip B1 that can apply blue ink in a strip shape in parallel. The marker chip LR1 and the marker chip B1 each protrude toward one end of the shaft body 10, and both marker chips LR1 and B1 are covered with a detachable flat cap 11 to prevent drying. The configuration of the two-color marker 1 is an example and is not particularly limited. Any configuration that allows marking with either of the two marker chips LR1 and B1 by gripping the shaft body 10 is acceptable. For example, the pink ink storage part LR may be housed in half of the cylindrical shaft body 10, and the blue ink storage part B may be housed in the other half, with marker chips protruding toward both ends of the shaft body, respectively, and each covered with a cylindrical cap. The ink used is preferably a fluorescent ink used in a so-called marker pen, but fluorescence is not essential. Also, the blue color may be light blue.

[0068] Both the horizontally long sheet 2 and the vertically long sheet 3 are resin plates with translucency, where the upper half is colored green and the lower half is colored red. When placed and covered on the pages of teaching materials such as textbooks, the printed black characters should be clearly visible through them without any problems. The sheet can be, for example, a sheet-shaped object formed by containing a coloring agent in a transparent resin, or a sheet-shaped object formed by a transparent resin and colored by applying paint or attaching a coloring film.

[0069] Considering the size of B5 version (width 182 mm × height 257 mm), which is the size of most textbooks and reference books, it is desirable that the sizes of the horizontally long sheet 2 and the vertically long sheet 3 be set to sizes that are easy for users to handle. In this embodiment, the size of the vertically long sheet 2 is preferably a width slightly smaller than the page width and a height about one-fourth to one-third of the page height, and the size of the horizontally long sheet 3 is preferably about half of the page width and about 80% of the page height. However, their sizes and thicknesses are not particularly limited. For example, many word memorization notebooks are of B6 version (width 128 mm × height 182 mm). For the use of memorizing words in a notebook of this size, a vertically long sheet with a size that can cover most of the page is suitable. Since A4 version is popular in recent years for the prints distributed as homework or reference materials, sheets of corresponding sizes can also be set.

[0070] Figure 8 is a schematic diagram showing the relationship between the colors of the sheet and the marker in the marker sheet set for memorization learning according to this embodiment. Since the pink color of the marker and the green color of the sheet, and the blue color of the marker and the red color of the sheet are in complementary color relationships respectively, for example, the characters of "iroha" marked with a pink marker will be completely blacked out and hidden when covered with a green sheet, but will not be hidden and the characters can be read when covered with a red sheet. Also, the characters of "nihohe" marked with a blue marker will have the opposite state of being hidden by the sheet.

[0071] FIG. 9 is an example showing a usage method of the memorization learning marker sheet set according to the present embodiment when a large number of words to be memorized are included in a textbook sentence as shown in FIG. 1 described above. As described above, if all the places (terms) to be memorized are marked with a single color and then covered with a sheet corresponding to the complementary color, all the markings will be hidden and the sentence will become meaningless. However, if the target terms are divided into two types and marked with pink and blue respectively, when covered with a green sheet, only the terms marked in pink will be hidden, and when covered with a red sheet, only the terms marked in blue will be hidden. As a result, the user can perform learning by deriving the hidden terms from information such as the unmarked sentence and the terms before and after that are not hidden. Moreover, by quickly rotating the sheet up and down, it is also possible to perform learning by switching between hiding / decipherability of the terms. Therefore, even in the case of a sentence in a single teaching material, a large number of terms can be hidden without becoming meaningless, and multi-faceted and efficient memorization learning of the terms included in the sentence becomes possible.

[0072] FIG. 10 is an example showing a usage method of the memorization learning marker sheet set according to the present embodiment in the case of memorization learning of the periodic table of chemistry as shown in FIG. 2 described above. As described above, if both the element symbol and the element name are marked with a single color, both will be hidden when the sheets are overlapped, and the teaching material will not be valid in the first place. However, for example, if the element symbol is marked in pink and the element name is marked in blue, when covered with a green sheet, only the element symbol will be hidden, and when covered with a red sheet, only the element name will be hidden. As a result, the user can perform two-way memorization learning such as "What is the element name of the element symbol S?" or "What is the element symbol of sulfur?", and moreover, by quickly rotating the sheet up and down, it is also possible to perform learning by appropriately switching between the two.

[0073] (Second Embodiment) FIG. 11 is a schematic diagram showing a two-color pen 4, a horizontally long sheet 5, and a vertically long sheet 6 that constitute the memorization learning pen sheet set according to the second embodiment of the present invention.

[0074] The two-color pen 4 has a bright orange (yellowish orange) ink storage part YO in the center of the cylindrical shaft body 40 and a pink ink storage part LR in the other half. At both ends of the shaft body 40, a bright orange pen tip YO2 and a pink pen tip LR2 that can write characters with a thin line are respectively protruded, and a cylindrical cap 41 is put on each to prevent drying. The configuration of the two-color pen 4 is also just an example, and as long as the shaft body 40 can be grasped to write fine characters, it is not particularly limited to this. The ink to be used is preferably fluorescent ink, but fluorescence is not necessarily essential.

[0075] Both the horizontally long sheet 5 and the vertically long sheet 6 are made of a translucent resin plate colored with a dark orange (reddish orange) RO in the upper half and a red R in the lower half. The configuration and size other than the color are the same as those of the sheets of the marker sheet set for rote learning.

[0076] Figure 12 is a schematic diagram showing the relationship between the colors of the sheets and pens of the marker sheet set for rote learning according to this embodiment. The color of the first pen is a brighter orange (yellowish orange) with higher brightness compared to the dark orange (reddish orange) in the upper half of the sheet. Therefore, when the bright orange characters written with the first pen tip YO2 are covered with the darker orange with lower brightness in the upper half of the sheet, the characters will blend into the color of the sheet and become invisible. Also, when covered with the red in the lower half of the sheet, since red is an analogous color to bright orange and has a lower brightness, the characters will also blend into the color of the sheet and become invisible.

[0077] On the other hand, when the pink characters written with the second pen tip LR1 are covered with the bright orange in the upper half of the sheet, since pink is an analogous color to bright orange and has a lower brightness, the characters can be read. However, when covered with the red in the lower half of the sheet, since red is the same color as pink and has an even lower brightness, the characters will become invisible.

[0078] Figure 13 shows an example of how to use the memorization learning pen sheet set according to this embodiment in the English reading comprehension teaching material as shown in FIG. 4 above. As described above, even if one tries to memorize by hand-writing the Japanese translation in orange pen below the English text, when the red sheet is overlaid, all the Japanese translations will be hidden, so it can only be a simple memorization teaching material to check whether the Japanese translation is visible or not.

[0079] However, as illustrated in FIG. 11, by writing the Japanese translation in bright orange characters with the first pen, and further adding reading hints such as underlines to emphasize important words, difficult-to-remember words, or symbols and phrases such as "S", "V", "O" representing syntactic structures in pink characters with the second pen, when the entire English text is covered with dark orange on the upper half of the sheet, the Japanese translation written in brighter orange with a higher brightness will become invisible, but the reading hints written in pink, which is a similar color with a lower brightness than bright orange, can be seen. Therefore, one can proceed with English reading comprehension relying on these hints.

[0080] Also, when covering the lower half of the sheet with red, both the Japanese translation written in brighter orange with a higher brightness and the hints written in pink will be hidden, and only the English text will be visible. However, by turning the sheet upside down so that the red is on top and sliding the color boundary line downward one line at a time, a step-by-step learning method is also possible, such as trying to read the English text relying on the previously visible hints and then making the correct Japanese translation visible immediately.

[0081] Figures 14 and 15 show examples of how to use the memorization learning pen sheet set according to this embodiment for memorization learning of classical Chinese or ancient Chinese. Since textbooks of Japanese, classical Chinese, and ancient Chinese are usually written vertically, it is appropriate to use the horizontally long sheet 5 after rotating it by 90°.

[0082] In FIG. 14, when the full translation is entered in bright orange on the left side of the classical Chinese text in the textbook, and auxiliary symbols such as dots, single and double dots, and furigana are entered in pink, and then covered with dark orange on the upper half of the sheet, the full translation becomes invisible, but the auxiliary symbols and furigana remain visible. In FIG. 15, when the modern language translation is entered in bright orange on the left side of the classical Chinese text in the textbook, and the meanings of difficult classical Chinese words and the supplementation of the subject omitted in the original text are entered in pink, and then covered with dark orange on the upper half of the sheet, the modern language translation becomes invisible, but the meanings of the classical Chinese words and the supplemented subject remain visible.

[0083] As described above, the memorization learning sheet, the marker sheet set for memorization learning, and the pen sheet set for memorization learning according to the present invention perform color-coding of markings such as words and phrases using two types of markers and additional writing of color-coded character information etc. using two types of pens on the pages of teaching materials such as textbooks, and then can appropriately switch the hiding of words and phrases and additional writing for each type using a sheet having two colors.

[0084] Thereby, memorization learning can be advanced from a simple task of "memorizing the correct answers" to a more multifaceted, organic, and step-by-step learning method such as "deriving the correct answers from the context (of the text)" or "deriving the correct answers from hints", and as a result, more efficient and less forgettable memorization learning can be realized. In addition, since the marking and additional writing can be arbitrarily performed by the user according to the classification that the user understands most easily, the user himself / herself can advance the teaching material to an original memorization teaching material optimal for himself / herself.

[0085] Furthermore, providing two color regions on a single sheet not only makes it possible to simply aggregate and compact the sheet into one for easy handling even in a train etc., but also allows the sheet to be slid on the teaching material to move the boundary line of the two colors line by line, enabling the hidden information to be seen sequentially step by step, thus making it possible to perform the above-mentioned multifaceted, organic, and step-by-step memorization learning method more precisely, and achieving a special effect that cannot be obtained with a conventional single-color sheet.

[0086] As described above, the embodiments of the present invention have been described with reference to the drawings. However, the present invention is not necessarily limited to the above-described configurations, and can be appropriately modified and implemented within the scope of achieving the object of the present invention and having the effects, and as long as they belong to the scope of the technical idea of the present invention, they belong to the technical scope of the present invention.
