When only a part of the configuration is described, the other parts of the configuration are the same as those described in the preceding section. Not only the combination of the parts specifically described in each embodiment, but also the embodiments can be partially combined as long as the combination does not hinder.

  FIG. 1 is a plan view of a character learning and educational tool 10 according to the first embodiment of the present invention. The character learning and learning tool 10 according to the first embodiment is a tool that gives a user an intellectual stimulus and learns characters by using image information and character information that are expressed by applying a predetermined liquid. In the first embodiment, it is assumed that the user is a child of an elementary school age or lower. The predetermined liquid is a liquid containing ferric chloride.

  The character learning and educational tool 10 according to the first embodiment is formed including a sheet-like member 11. The sheet-like member 11 has water absorption and flexibility. On one surface perpendicular to the thickness direction of the sheet-like member 11, a shape of a predetermined object and a character 13 related to the predetermined object are formed. One surface perpendicular to the thickness direction of the sheet-like member 11 is a listable region 14. At least one of the shape of the predetermined object and the character 13 related to the predetermined object is formed by applying and drying a yellow blood salt aqueous solution.

Yellow blood salt is sometimes referred to as potassium hexacyanoferrate (II), potassium ferrocyanide, or yellow blood potash, and dissolves 32.0 g in 100 grams of water (gram, abbreviated “g”) at 25 degrees Celsius. Yellow blood salt produces ferrocyanide represented as [Fe (CN) ₆ ] ^{4− in} a state dissolved in water.

The characters 13 formed in the listable area 14 are a part of the characters 13 from the beginning of the character string representing the names of predetermined objects. The character learning and educational tool 10 according to the first embodiment is configured to further include a ferric chloride aqueous solution. Ferric chloride is sometimes referred to as iron (III) chloride and is readily soluble in water, ethanol, ether and acetone. The anhydride represented as Fe ₂ Cl ₆ dissolves 74.4 g in 100 g of water at 0 degrees Celsius. Hexahydrate, denoted Fe ₂ Cl ₆ · 6H ₂ O, in 0 degrees Celsius, melts 246g of water 100 g. When placed in boiling water, it hydrolyzes to a reddish brown iron (III) hydroxide colloidal solution.

When ferric chloride is dissolved in a solvent containing water, it hydrolyzes to produce ferric ions expressed as Fe ³⁺ .

When yellow blood salt and ferric ions come into contact in solution, iron (III) ferrocyanide is produced by an ionic reaction. This produces ferric ferrocyanide (III). Iron ferrocyanide (III) is expressed as Fe ₄ [Fe (CN) ₆ ] ₃ and is a deep blue insoluble solid, iron (III) hexacyanoferrate (II), insoluble Prussian blue, Berlin blue, bitumen, Sometimes called Belence, Paris Blue Bronze Blue or Bronzeless Blue.

  The character 13 is a part of the character 13 from the beginning of the character string representing the name of a predetermined object. The character learning and educational tool 10 according to the first embodiment further includes a liquid 16 in which ferric chloride is dissolved, which is applied to a portion where a yellow blood salt aqueous solution is applied and dried.

  In the first embodiment, in the listable region 14, at least one of the shape of the object and the character 13 is formed by applying and drying a yellow blood salt aqueous solution. When a liquid containing trivalent iron ions, such as a ferric chloride aqueous solution, is applied to the portion to which the yellow blood salt aqueous solution has been applied, the portion where the yellow blood salt aqueous solution has been applied and dried develops color. Thereby, the shape of the thing formed by apply | coating and drying a yellow blood salt aqueous solution, or the character 13, or both expresses visually.

  When the user of the character learning and educational tool 10 according to the first embodiment applies the liquid 16 in which ferric chloride is dissolved, the user is visually stimulated by coloring. As a result, the user's attention is directed to the contents formed in the listable area 14. While applying the liquid 16 in which ferric chloride is dissolved, the user can select at least one of the shape of the portion 14 that can be visually recognized from the already visible region 14, the shape of the portion that does not yet appear, and the character 13. Either one can be predicted. The user confirms the pros and cons of the prediction by comparing the prediction with the shape and character of the object that is manifested by applying a liquid in which ferric chloride is dissolved. As a result, the user learns the relationship between the shape of the object and the character and learns the character.

  In the first embodiment, the characters 13 formed in the listable area 14 are some characters 13 from the beginning of a character string representing a predetermined name of the object to which the characters 13 relate. The user remembers the name of the object once stored by using a part of the characters 13 from the head as a clue to remember the name of the object. Further, even if the user applies the liquid 16 in which ferric chloride is dissolved to the entire listable area 14, the character 13 formed in the listable area 14 is a character string representing the name of an object. Because it is a part, it prevents the user from easily knowing the entire name of the object, and the user is forced to remember the name of the object. Thereby, the character learning and educational tool 10 gives an intellectual stimulus to the user.

  The character learning and educational tool 10 further includes a liquid 16 in which ferric chloride is dissolved, which is applied to a portion where a yellow blood salt aqueous solution is applied and dried. The user applies a yellow blood salt aqueous solution and dries it, and then applies liquid 16 in which ferric chloride is dissolved to the portion, so that the shape or character 13 Or both are expressed.

In the first embodiment, the character learning and educational tool 10 is formed including paper as the sheet-like member 11. The paper is formed in a sheet shape, and the surface portion forming one surface perpendicular to the thickness direction of the paper is a listable region 14. The paper is assumed to be white paper having a thickness of about 75 g per square meter (meter square, abbreviation “m ² ”). Hereinafter, the region 14 of the sheet-like paper that can be listed in the direction perpendicular to the thickness direction may be referred to as “paper surface”, and the portion of the paper that defines the paper surface may be referred to as “paper surface portion”.

  In the first embodiment, the predetermined object is a rabbit, and the predetermined shape of the object is a design simulating a rabbit. In the present invention, the animals belonging to the order Rabbits are called “rabbits”, and a design simulating a rabbit is shown with emphasis and omission as long as it can be recognized as a rabbit. Also good. In the present invention, the shape of the object may be realistic or non-realistic, and may be a stylized shape including emphasis and omission. The design simulating a rabbit in the first embodiment is a design simulating the whole of an individual rabbit.

  In the first embodiment, the character 13 is a hiragana character “U” written in hiragana. The typeface of character 13 is not specified. A design simulating a rabbit is drawn with black paint. The letter “u” 13 is written in yellow blood salt solution and dried. Hereinafter, of the members forming the listable region 14, the portion infiltrated with the yellow blood salt aqueous solution is referred to as “yellow blood salt infiltrated region 17”. When the shape of the object and the character 13 are drawn as a line having a thickness by applying and drying a yellow blood salt aqueous solution, the region occupied by the line having the thickness is the yellow blood salt infiltrating region 17.

  The region to which the yellow blood salt aqueous solution is not applied is excluded from the yellow blood salt infiltrating region 17, whether it is a blank region included in the shape of an object or a blank region included in a line constituting the character 13. . The yellow blood salt infiltrating region 17 was applied with yellow blood salt to infiltrate and dry to form the shape of the object, and yellow blood salt was applied to infiltrate and dried to form the character 13. Part. Hereinafter, applying a liquid and infiltrating the listable region 14 to form the shape of the object is referred to as “drawing”, and applying the liquid to the listable region 14 and infiltrating to form the character 13. This is sometimes referred to as “drawing”.

  In the first embodiment, a design simulating a rabbit and a hiragana character “U” are drawn on one paper surface. After being drawn, the paper is dried. Therefore, this design and this hiragana character are formed in the listable area 14. The hiragana character “U” indicates that the design drawn on the surface of the paper on which the hiragana character is written is a rabbit. The hiragana character “U” is a partial character 13 from the beginning of the character string “Rabbit” representing the name of the rabbit, and is one character from the beginning.

  Since this hiragana character is drawn and dried with a yellow blood salt aqueous solution, this hiragana character “U” cannot be visually recognized when the white paper is dried. The state in which the shape of the object and the character 13 are drawn and dried is a state in which the character learning and educational tool 10 can be used and is in a state before the user uses it.

  The user uses the character learning and educational tool 10 by applying the ferric chloride aqueous solution to the listable region 14. The part to which the ferric chloride aqueous solution is applied by the user includes the yellow blood salt drawing area in the paper surface portion when viewed on the paper surface along the thickness direction of the paper, and it is applied to a wider area than this. Is desirable. Furthermore, the user starts application from one side in any direction parallel to the paper surface, and applies the application to the paper surface portion on the other side in any one direction. It is desirable to carry out it later than the application | coating to. As a result, the yellow blood salt infiltrating region 17 is colored from one side in any one of the above directions, and the drawn character “U” 13 appears from one side in any one of the above directions.

  The user can recognize the rabbit as a rabbit by looking at the design simulating a rabbit, the knowledge that the rabbit is pronounced “rabbit”, and the hiragana character “u” in Japanese It is desirable to have knowledge that As a result, the user looks at the design simulating a rabbit and tries to recall the pronunciation “rabbit”. When you cannot remember the pronunciation “rabbit”, or when you confirm that the rabbit design is represented by the pronunciation “rabbit”, apply ferric chloride aqueous solution to the paper. In the present invention, “Japanese” means Japanese as of the filing date of the present invention. In particular, the Japanese currently used in Japan is sometimes referred to as “modern Japanese” in contrast to Japanese before the Edo period.

  When the pronunciation of “rabbit” cannot be remembered, when a part of the character 13 “U” is expressed, the possibility of the character 13 “U” is recognized from the shape of the part of the expressed character 13 To do. The user recalls that the design simulating the rabbit is the shape of the object indicated by the name starting with the pronunciation “U”, using the shape of a part of the expressed character 13 as a clue. This recall helps me remember and remember the relationship between the shape of the rabbit and the pronunciation of “rabbit”.

  If the character 13 “U” cannot be recalled even if a part of the character 13 “U” is visually recognized, the aqueous ferric chloride solution is applied to a wider area of the paper. This suggests that the entire character 13 “U” is expressed, and that the pattern simulating a rabbit is represented by the pronunciation “Rabbit”. If the user looks at the letter “U” and recalls the pronunciation of “U”, it is certain that the design simulating the rabbit is the shape of the object indicated by the name starting with the pronunciation “U”. This belief helps to recall and remember the memory of the relationship between the rabbit shape and the pronunciation of “rabbit”.

  In order to give an intellectual stimulus to the user, a part of the character string representing the name of the predetermined object is one character from the beginning of the character string representing the name. There is. The names of objects represented in Japanese can be expressed in all hiragana characters, and the type of hiragana characters that can be the first character of the character string that represents the name of an object is, among all hiragana characters, There are 73 types. This includes 40 types included in “A line” to “Ma line” and “Ra line”, “Ya”, “Yu”, “Yo”, “Wa”, “O”, “N”, This is the number of types of hiragana characters by adding “ゑ” and “ゑ” and adding 25 types representing muddy sound and semi-turbid sound. The character 13 expressed by adding a semi-voiced sound point to “Sa line” is not included in the 73 types because it is not used in modern Japanese. In addition, it is assumed that the roaring sound including the open sound and the mellow sound is two characters in the hiragana character notation, and the lower case character representing the roar is excluded from the type of the hiragana character that can be the first character.

  “O”, “N”, “ゐ”, and “ゑ” are characters that represent the name of an object in modern Japanese because they are rarely the first character of the character string that represents the name of an object. There are 69 types of hiragana characters that are the first character of, almost all of them. Therefore, there are 69 or 73 characters 13 written in the listable area 14. When the shape of various objects is shown to the user and the corresponding hiragana character is written as the first character of the character string representing the name, the types of characters 13 that can be expressed can be limited to 73 types. As a result, it is possible to classify the shapes of more than 73 types of objects into 73 types by classifying them according to the type of the first character of the character string representing the name of the object. Can be shown.

  The less the content to be stored, the less labor it takes to memorize, and the less effort, the easier it is to achieve. Guiding the user by limiting the types of hiragana characters to be stored as the first character of the character string representing the name of the object to 73 types, thereby facilitating the achievement of the user and the user's willingness to learn Can be promoted.

  When the user applies the aqueous ferric chloride solution, it is desirable to apply it with one of the brushes including a paint brush and a calligraphy brush. Hereinafter, a brush including a paint brush and a calligraphy brush is simply referred to as a “brush”. The user can get used to having a brush by applying a ferric chloride aqueous solution with a brush. Using a brush is also an educational stimulus to the user.

The concentration of ferric chloride in the aqueous ferric chloride solution to be applied ranges from several millimoles per liter (abbreviation “mmol / l”) to 4 molar parts (mol).
per liter, abbreviation “mol / l”), more preferably about several mmol / l to 10 mmol / l. The ferric chloride aqueous solution does not contain a chemical species that absorbs visible light when excited by visible light and undergoes electronic transition. Therefore, even if the ferric chloride aqueous solution is applied on paper containing no yellow blood salt, the applied ferric chloride aqueous solution is almost colorless and transparent.

The yellow blood salt infiltrating region 17 is a state where yellow blood salt crystals are scattered between paper fibers in a dry state. When the ferric chloride aqueous solution comes into contact with the yellow blood salt infiltrating region 17, the yellow blood salt is dissolved in the water contained in the ferric chloride aqueous solution. Immediately after the yellow blood salt has dissolved, the concentration of the yellow blood salt in the solution is lower than the ferric chloride in the solution. In a solution, if the concentration of yellow blood salt is equal to the concentration of ferric chloride, or if the yellow blood salt is present in excess relative to ferric chloride, FeK [Fe (CN) ₆ ]. A soluble Prussian blue represented by H ₂ O results. Soluble Prussian blue dissolves in water to form a dark blue solution. In the first embodiment, since the concentration of yellow blood salt is lower than the concentration of ferric chloride, soluble Prussian blue does not occur, so that the developed deep blue yellow blood salt infiltrating region 17 does not bleed.

In the first embodiment, the chemical reaction when the yellow blood salt infiltrating region 17 is colored is represented by the following ion reaction formula (1).
3K ₄ [Fe (CN) ₆ ] + 4Fe ³⁺ → Fe ₄ [Fe (CN) ₆ ] ₃ + 12K ⁺
... (1)

The chemical reaction formula is represented by the following formula (2).
3K ₄ [Fe (CN) ₆ ] + 4FeCl ₃ → Fe ₄ [Fe (CN) ₆ ] ₃ +12 KCl
... (2)

  Since this reaction is an ionic reaction, within a few nanoseconds (abbreviated “ns”) to a few microseconds (microsecond, abbreviated “μs”) after the trivalent iron ions contact with the yellow blood salt, The reaction between the contacted ions ends.

  Although all compounds have intakes that are considered to be harmful to the human body when ingested for a short time, all of yellow blood salt, ferric chloride, ferric ferrocyanide and potassium chloride It is a safe compound that does not fall under the category of poisonous substances, deleterious substances or specific poisonous substances under Japanese law. Ferrocyan compounds are also used as food additives and are safe.

For example, lethal dose of potassium chloride when administered orally to rats (
lethal dose 50, abbreviated as “LD50”), 3020 milligrams per kilogram (
Judging from the value of milligram per kilogram (abbreviation "mg / kg")
The lethal dose for a human with kilogram (abbreviated as “kg”) is 60 grams (gram, abbreviated as “g”) or more per person. If a value of 2600 g / kg is used as the LD50 of acute oral toxicity, the acute oral lethal dose for a human weighing 20 kg is 50 g or more per person. These LD50 values are almost the same as the laundry detergent. Therefore, potassium chloride when administered orally is not worth the poison.

  Therefore, the compound used for the character learning and educational tool 10 is safe for users including children. Therefore, when the character learning and learning tool 10 is used, it is safe even if a compound contained in the character learning and learning tool 10 and a compound generated by using the character learning and learning tool 10 enter the user's body orally. There is no problem above. Moreover, when the user uses the character learning and educational tool 10 on the desk or in the room, there is no need to use a compound as much as the above-mentioned amount as a lethal dose, which causes a problem for the health user. There is no.

  According to the first embodiment, at least one of the shape of the object and the character 13 is formed in the listable region 14 by applying and drying a yellow blood salt aqueous solution. Thus, by applying a liquid containing trivalent iron ions, for example, a liquid 16 in which ferric chloride is dissolved, a portion of the yellow blood salt aqueous solution applied and dried can be colored. Therefore, it becomes possible to display at least one of the shape of the thing formed by apply | coating and drying yellow blood salt aqueous solution and the character 13 so that visual recognition is possible.

  When the user of the character learning and educational tool 10 according to the first embodiment is applied with the liquid 16 in which ferric chloride is dissolved, the visual stimulation is given to the user by coloring and the listable area 14 It is possible to direct the user's attention to the contents formed in the above. In addition, while applying the liquid 16 in which ferric chloride is dissolved, at least one of the shape of the part that can be visually recognized from the already visible region 14 and the part that does not yet appear and the character 13 It is possible to prompt the user to predict one of them. The user can confirm the pros and cons of the prediction by comparing the prediction with the shape and character of the object that appears by applying a liquid in which ferric chloride is dissolved. Therefore, the user can learn the relationship between the shape of the object and the character. This makes it possible for the user to learn characters.

  Further, according to the first embodiment, the characters 13 formed in the listable region 14 are some characters 13 from the beginning of a character string representing a name of a predetermined thing related to the character 13. As a result, it is possible to assist the user to remember the name of the object once stored. Further, even when the liquid 16 in which ferric chloride is dissolved is applied to the entire listable area 14, the character 13 formed in the listable area 14 is a part of the character string representing the name of the object. Because there is, it is possible to force the user to remember the name of the object.

  In addition, according to the first embodiment, the character learning and educational tool 10 further includes the liquid 16 in which ferric chloride is dissolved, which is applied to a portion where the yellow blood salt aqueous solution is applied and dried. . As a result, it is possible to apply the liquid 16 in which ferric chloride is dissolved to the portion where the yellow blood salt aqueous solution is applied and dried.

On the paper constituting the booklet 18, the shape of the character forming the story and the character string representing the character of the character are formed by the black ink and the yellow blood salt aqueous solution. The character is the predetermined object, and the shape of the character is the shape of the predetermined object. The dialogue of the character is the character 13.

  The thing that appears in the story formed in the booklet 18 is an animal and personified. Anthropomorphized animals speak Japanese or foreign languages in the story. On the first few sheets of the booklet 18, the animals appearing in the story and a part from the beginning of the character string representing the name of the animal are drawn. Further, it may include a page in which an object appearing in a scene drawn by a story, for example, a building, a vehicle, nature, or a plant is drawn.

  FIG. 2 shows the character learning and educational tool 10 when the object is a rabbit and the shape of the object is a design in which the rabbit is anthropomorphic. In FIG. 2A, a character 13 is a hiragana character “Usa” which is two characters from the beginning of a character string representing the name of a rabbit. FIG. 2B shows the character learning and educational tool 10 when the object is a giraffe and the shape of the object is a design in which the giraffe is anthropomorphic. In FIG. 2A, a character 13 is a hiragana character “Kiri” which is two characters from the beginning of a character string representing the name of the giraffe. In the present invention, the giraffe is assumed to be a giraffe genus giraffe and includes subspecies. The shape of the rabbit shown in FIG. 2A is an anthropomorphic design of a rabbit called a “rop ear” whose ears hang down.

  In FIG. 2, the shape of the rabbit and the shape of the giraffe are drawn with black paint, and the hiragana character “Usa” and the hiragana character “Kiri” are written in a yellow blood salt aqueous solution and dried. Is done. The shapes and characters 13 of these objects shown in FIG. 2 are a part of the pages included in the booklet 18 in the second embodiment, and in addition to these, various characters and shapes of objects appearing in the story are drawn.

The user recognizes the letters “Let's get here” written in black paint, and puts the liquid 16 in which ferric chloride is dissolved at the position ahead of the arrow 22 indicated by the arrow 22. Apply. As a result, the letters 13 “let's get here” formed as the yellow blood salt infiltrating region 17 and the next arrow 24 appear in a visible manner. The user recognizes the letter “Let's get here” 13 and the next arrow 24 which are expressed by applying the liquid 16 in which ferric chloride is dissolved, and is indicated by the next arrow 24. A liquid 16 in which ferric chloride is dissolved is further applied to the position. As a result, the character 13 “Let's do well” appears in a visible manner.

  In the second embodiment, a character 13 “Let's get here” formed as the yellow blood salt infiltrating region 17 is a character display 21 representing an instruction to the user. A symbol other than the character display 21 written in characters, for example, including the next arrow 24 may be further drawn and dried as the yellow blood salt infiltration region 17. In the paper surface shown in FIG. 3, the display 19 showing the position of the yellow blood salt infiltrating region 17 is formed by a visible paint at a position surrounding the character 13 “Let's do well” when the paper surface is viewed perpendicularly to the paper surface. Is done. In the second embodiment, the display 19 indicating the position of the yellow blood salt infiltrating region 17 is an angle bracket drawn as a line bent at a right angle. The brackets are drawn with black paint in a shape that defines the yellow blood salt infiltration region 17 from the lower left, upper left, upper right, and lower right. The top, bottom, left and right are directions parallel to the paper surface.

  FIG. 4 is a plan view of the character learning and educational tool 10 according to the second embodiment of the present invention. In the booklet 18, a page following the paper on which the story is drawn describes the characters who appeared in the story. FIG. 4 shows the character learning and learning tool 10 when the object is an elephant and the shape of the object is the shape of a part of the elephant. The shape of a part of the elephant is the shape of a part of the elephant including the elephant's nose. In the present invention, elephant animals are collectively referred to as “elephant”. Elephants are sometimes referred to as long nose eyes. In FIG. 4, the character 13 is both a character 13 that is a Japanese character string that represents the name of an elephant and a character 13 that is an English character string that represents the name of the elephant. This character string is written as an alphabetic character 13 of uppercase letters 13.

  On the paper surface shown in FIG. 4, all of the shape of a part of the elephant drawn here is formed as the yellow blood salt infiltrating region 17. The letters “ELEPHANT” 13 are drawn with black paint. The character 13 “zou” is formed as a yellow blood salt infiltrating region 17. As the display 19 indicating the position of the yellow blood salt infiltrating region 17, both the display 19 indicating the position of a part of the elephant partial shape and the display 19 indicating the position of the character 13 "Elephant" are both included. Drawn with black paint. Of the shape of a part of the elephant, the other part excluding the further part is located outside the region shown in the display 19 indicating the position of the yellow blood salt infiltrating region 17. In FIG. 4, the other part excluding the part is the shape of an elephant fang.

  The display 19 indicating the position of the yellow blood salt infiltrating region 17 shown in FIG. 4 shows the upper left and lower left corners of the part where the shape of a part of the elephant including the elephant's nose is drawn. Drawn. Since the display 19 indicating the position of the yellow blood salt infiltrating region 17 is in the shape of a bracket, the yellow blood salt infiltrating region 17 is positioned on the right side of the two displays 19 of the upper bracket and the lower bracket. Indicates to do.

  The user applies the liquid 16 in which ferric chloride is dissolved to the page preceding the page shown in FIG. 4 in the character learning and educational tool 10 according to the second embodiment, and the character drawn there is displayed. It shall be remembered. If the user does not know the English name representing the elephant, the user cannot know what the character 13 “ELEPHANT” means by looking at the character 13 “ELEPHANT”. However, by recognizing the display 19 indicating the yellow blood salt infiltrating region 17, the liquid 16 in which ferric chloride is dissolved is applied to the paper surface at the position indicated by the display 19. As a result, at least one of the shape of a part of the elephant and the character 13 “Elephant” appears in a visible manner.

  The user can recall the entire elephant by looking at the shape of a part of the elephant that appeared in the story. If you remember the name of the elephant that appeared in the story, you can recall the Japanese word “Elephant”. If the shape of the whole elephant is recalled, it is predicted that a part of the shape of the elephant exists outside the region shown in the display 19 showing the yellow blood salt infiltrated region 17, and the yellow salt infiltrated region 17 The liquid 16 in which ferric chloride is dissolved is applied to a wider area than the area indicated by the display 19 indicating. In this way, the shape of the elephant fangs is developed and visually confirmed.

  By displaying at least one of the shape of a part of the elephant and the character 13 of “Elephant” in the listable area 14 where the English character 13 of “ELEPHANT” is formed, “ELEPHANT” It can be learned that the English character 13 corresponds to the Japanese language of elephant and “Elephant”. In addition, by drawing the shape of the character appearing on the preceding page or a part thereof on the subsequent page, it becomes possible to review the shape of the stored object and its name.

  According to the second embodiment, the listable area 14 is an area formed on the surface of the sheet-like member 11, and the sheet-like member 11 is bound to form a booklet 18. This facilitates carrying a plurality of sheets. In addition, the order in which a plurality of sheets are arranged can be defined. Thus, the story can be described by using the shape of the object and the character 13 associated therewith as the story's character and the dialogue of the character. In addition, by causing the user to perform color development processing in accordance with the order in which the sheet-like members 11 are arranged, it is possible to make the user distinguish between a visually recognized part and a part that has not yet been visually recognized.

  According to the second embodiment, the character 13 formed in the listable region 14 includes the character 13 in which character strings in different languages are written together. Recognize existence. It can also assist the user in learning different languages.

  Further, according to the second embodiment, the predetermined shape of the object is the shape of a part of the object represented by the character 13. This can assist the user in remembering the shape of the object represented by the character 13. Even when the liquid 16 in which ferric chloride is dissolved is applied to the entire listable area 14, the shape of the object formed in the listable area 14 is the shape of a part of the object represented by the character 13. Because it is, the user can be forced to remember the shape of the object.

  Moreover, according to 2nd Embodiment, the character learning and educational tool 10 is further comprised including the display 19 which shows the position of the part which apply | coated and dried yellow blood salt aqueous solution. Thereby, it is possible to display which portion of the listable region 14 is the portion where the yellow blood salt aqueous solution is applied and dried. Accordingly, by displaying the area where the liquid 16 in which ferric chloride is dissolved is displayed, the area in which the liquid 16 in which ferric chloride is dissolved can be reduced. Thereby, it is possible to reduce the trouble of applying the liquid 16 in which ferric chloride is dissolved.

  In addition, according to the second embodiment, a character display 21 representing an instruction for the user is further formed in the listable area 14, and the character display 21 representing the instruction is applied with a yellow blood salt aqueous solution and dried. Is formed. Therefore, the user can recognize what should be done next by applying the liquid 16 in which ferric chloride is dissolved and reading the character display 21 displayed along with this. Since what to do next is displayed sequentially, the user can recognize the progress of the work. This allows the user to feel a sense of accomplishment in performing the work. Since the user needs to read the character display 21, and reading the character display 21 promotes understanding of the work content, the importance of reading the character display 21 and being able to read the character display 21 is important. Can be felt by the user. Therefore, it is possible to prompt the user to read the character display 21.

  FIG. 5 is a plan view showing the character 13 written on the character learning and educational tool 10 according to the third embodiment of the present invention. In the third embodiment, the character 13 includes a plurality of characters formed by applying and drying a yellow blood salt aqueous solution, and is displayed as a character of a portion in which a part of the plurality of characters is formed. A thin film 26 that suppresses or prevents moisture permeation is formed on the surface on the side to be processed.

  In addition, the thin film 26 is formed on the surface of the listable region 14 where a plurality of characters are formed, on the side that is displayed as characters, and the portion covered by the thin film 26 is from the side that is displayed as characters. As seen, the area of the portion covered with the thin film 26 when viewed from the side that is formed wider than the portion coated and dried with an aqueous solution of yellow blood salt to form the character and displayed as a character, The difference between the area of the portion where the yellow blood salt aqueous solution is applied and dried to form 13 differs depending on the character covered by the thin film 26.

  The liquid 16 in which ferric chloride is dissolved is a solution containing ferric chloride as a solute and miscible with water and containing an organic compound that is liquid at room temperature and water as a solvent.

  The character 13 includes a plurality of characters formed by applying and drying a yellow blood salt aqueous solution, and prevents moisture from penetrating on the surface of a part of the plurality of characters formed. A thin film 26 is formed. As a result, when the liquid 16 in which ferric chloride is dissolved is applied, the liquid 16 in which ferric chloride is dissolved penetrates into the surface portion where the thin film 26 is formed by the yellow blood salt aqueous solution. The time to do is delayed with respect to the time when the liquid 16 in which ferric chloride is dissolved is applied.

  As a result, the character formed with the yellow blood salt aqueous solution on the surface portion where the thin film 26 is not formed is formed on the surface portion where the thin film 26 is formed with the yellow blood salt aqueous solution from the time when the thin film 26 is formed. Delays the time that is displayed in a visible manner. A plurality of characters displayed by applying the liquid 16 in which ferric chloride is dissolved are sequentially displayed with a difference in display time in the order to be read.

  The thin film 26 is formed on the surface of a portion of the listable region 14 where a plurality of characters are formed, and the portion covered by the thin film 26 is coated with a yellow blood salt aqueous solution when viewed from the side displayed as characters. It is formed wider around the dried portion. The difference between the area of the portion covered by the thin film 26 and the area of the portion where the yellow blood salt aqueous solution has been applied and dried varies depending on the character. Accordingly, the time from the application of the liquid 16 in which ferric chloride is dissolved until the liquid 16 in which ferric chloride is dissolved permeates into the portion where the yellow blood salt aqueous solution has been applied and dried varies depending on the character. Make it.

  Thus, when the liquid 16 in which ferric chloride is dissolved is applied to the entire listable region 14, the time when the letters formed by applying and drying the yellow blood salt aqueous solution are visibly displayed is displayed. , Change for each character. A plurality of characters displayed by applying the liquid 16 in which ferric chloride is dissolved are sequentially displayed with a difference in display time in the order to be read.

  The solvent contains water as a part of this, and contains ferric ions in the liquid 16 in which the ferric chloride is dissolved. The ferric ion chemically reacts with the yellow blood salt at the portion where the yellow blood salt aqueous solution is applied and dried, whereby the portion where the yellow blood salt aqueous solution is applied and dried is visibly colored. The liquid 16 in which the ferric chloride is dissolved contains an organic compound that is miscible with water and is liquid at room temperature as a part of the solvent. Thus, the time from application of the liquid 16 in which ferric chloride is dissolved to the listable region 14 to drying of the solvent containing ferric chloride as a solute is shorter than when the solvent is water. Shortened. Therefore, when the user's fingers and the other sheet-like member 11 come into contact with the surface of the sheet-like member 11, the liquid 16 in which ferric chloride is dissolved infiltrates the user's fingers and the other sheet-like member 11. The potential time is reduced compared to when the solvent is water.

  In the third embodiment, the listable area 14 is formed on the same paper as in the first embodiment. The character 13 is three hiragana characters “Kirin”. These three characters are formed so as to be legible when viewed from one side in the thickness direction of the paper surface. Hereinafter, one thickness direction of the paper surface is referred to as “one paper surface direction”. Further, when “outward” or “inward” is referred to on the paper surface, these are outward or inward directions in a direction parallel to the paper surface. In the third embodiment, it is assumed that the user applies the liquid 16 in which ferric chloride is dissolved in a range including the yellow blood salt infiltrating region 17 in the listable region 14 within a few seconds to a few dozen seconds. And

  The three letters “Kirin” are formed as a yellow blood salt infiltrating region 17 and are written with lines of the same thickness. Of these three characters, a thin film 26 is formed on the surface of the yellow blood salt infiltrating region 17 of “RI” and “N”. The thin film 26 is formed on the surface on one side in the paper surface direction of the paper surface. The thin film 26 prevents water from penetrating from one side of the paper surface to the other. The thin film 26 is formed from a polymer. The thin film 26 includes at least one of polyethylene and polyvinylidene chloride, and preferably does not dissolve in ethanol and acetone.

  The thin film 26 is not formed on one side in the paper surface direction of the yellow blood salt infiltrating region 17 forming the character “ki”. A thin film 26 covering one side in the direction of the paper of the word “ri” spreads outside the yellow blood salt infiltrating region 17 forming the line of the letter “ri”. The outline of the thin film 26 covering the yellow blood salt infiltrating region 17 with the letter “ri” as viewed from one side in the paper plane is 1 millimeter (millimeter, Abbreviation “mm”) extends outward. A thin film 26 covering one side in the direction of the letter “n” extends outward from the yellow blood salt infiltrating region 17 forming the line “n”. When viewed from one side in the paper direction, the outline of the thin film 26 covering the yellow blood salt infiltrating area 17 with the letter “n” extends outward by 3 mm with respect to the outline of the yellow blood salt infiltrating area 17 with the letter “n”. Exists.

  The character “Kirin” 13 is a hiragana character to be read in the order of “ki”, “ri”, “n”. The distance that the outline of the thin film 26 separates from the outline of the yellow blood salt infiltrating region 17 is set to be larger as the order of reading is later. When the user applied the liquid 16 in which ferric chloride was dissolved in a range including the yellow blood salt infiltrating region 17 forming the characters “ri” and “n” on the paper surface, the ferric chloride was dissolved. The liquid 16 immediately infiltrates the yellow blood salt infiltrated region 17 having the character “KI”, whereby the yellow blood salt infiltrating region 17 is colored and the character “KI” is developed.

  The liquid 16 in which ferric chloride is dissolved cannot infiltrate from one side of the paper surface into the yellow blood salt infiltrating region 17 of “RI”. Infiltrates from the outside. Accordingly, the time from the application of the liquid 16 in which ferric chloride is dissolved until the character is developed is longer in the case of the “ri” character than in the case of the “ki” character. The liquid 16 in which ferric chloride is dissolved cannot infiltrate into the yellow blood salt infiltrating area 17 of “n” from one side of the paper surface. Infiltrates from the outside.

  The distance at which the contour of the thin film 26 is separated from the contour of the yellow blood salt infiltrating region 17 is longer in the “n” character than in the “ri” character. Accordingly, after the liquid 16 in which ferric chloride is dissolved is applied around the yellow blood salt infiltrating area 17 of “N”, ferric chloride is applied to the yellow blood salt infiltrating area 17 of “N”. The time until the dissolved liquid 16 infiltrates the yellow blood of “RI” after the liquid 16 in which ferric chloride is dissolved is applied around the yellow blood salt infiltrating region 17 of “RI”. It is longer than the time until the liquid 16 in which ferric chloride is dissolved in the salt infiltration region 17. Accordingly, the time from the application of the liquid 16 in which ferric chloride is dissolved until the character is developed is longer in the case of the “n” character than in the case of the “ri” character.

  Therefore, when the liquid 16 in which ferric chloride is dissolved is applied almost simultaneously to the range including the yellow blood salt infiltrating region 17 of the character 13 of “Kirin”, the character 13 of “Kirin” becomes “Ki”, “Ri”. , Expressed in the order of “n”.

Ferric chloride dissolves not only in water but also in organic compounds that are liquid at room temperature, such as ethanol, ether, and acetone. In the present invention, a temperature range of 23 degrees Celsius or more and less than 27 degrees Celsius is referred to as “normal temperature”. Hereinafter, an organic compound that is liquid at room temperature is referred to as an “organic solvent”. In the third embodiment, the liquid 16 in which ferric chloride is dissolved contains water and ethanol as a solvent for dissolving ferric chloride. Ferric chloride, in an organic solvent, because the dissolution as a molecule represented by FeCl _3, the amount of material present as trivalent iron ions is small. By containing water in this, ferric chloride hydrolyzes and generates trivalent iron ions. This causes a reaction that develops color upon contact with yellow blood salt.

  Of the organic solvents ethanol, ether, and acetone, ether is not preferable as a solvent for dissolving ferric chloride in the third embodiment because it is not miscible with water. Ethanol and acetone are miscible with water. When two liquids are mixed in any composition, mixing without phase separation is called mixing. Among ethanol and acetone, acetone dissolves a polymer more easily than ethanol. Therefore, the solvent for dissolving ferric chloride preferably contains ethanol as an organic solvent. However, acetone does not dissolve all polymers.

  Further, according to the third embodiment, the character 13 includes a plurality of characters formed by applying and drying a yellow blood salt aqueous solution, and a surface of a portion where a part of the plurality of characters is formed. A thin film 26 for preventing moisture penetration is formed on the top. As a result, when the liquid 16 in which ferric chloride is dissolved is applied, the liquid 16 in which ferric chloride is dissolved penetrates into the surface portion where the thin film 26 is formed by the yellow blood salt aqueous solution. The time to do can be delayed with respect to the time when the liquid 16 in which ferric chloride is dissolved is applied.

  Therefore, the character formed with the yellow blood salt aqueous solution on the surface portion where the thin film 26 is not formed has a character formed with the yellow blood salt aqueous solution on the surface portion where the thin film 26 is formed with respect to the time when the thin film 26 is formed to be visible. The time displayed so as to be visible can be delayed. Accordingly, it is possible to sequentially display a plurality of characters displayed by applying the liquid 16 in which ferric chloride is dissolved, with a difference in display time in the order to be read.

  In addition, according to the third embodiment, the thin film 26 is formed on the surface of a portion of the listable region 14 where a plurality of characters are formed, and the portion covered by the thin film 26 is viewed from the side displaying characters. Thus, a yellow blood salt aqueous solution is formed wider around the coated and dried part. The difference between the area of the portion covered by the thin film 26 and the area of the portion where the yellow blood salt aqueous solution has been applied and dried varies depending on the character. Accordingly, the time from the application of the liquid 16 in which ferric chloride is dissolved until the liquid 16 in which ferric chloride is dissolved permeates into the portion where the yellow blood salt aqueous solution has been applied and dried varies depending on the character. Can be made.

  Therefore, when the liquid 16 in which ferric chloride is dissolved is applied to the entire listable region 14, the time at which characters formed by applying and drying the yellow blood salt aqueous solution are displayed in a visible manner, It can be changed for each character. Accordingly, a plurality of characters displayed by applying the liquid 16 in which ferric chloride is dissolved can be sequentially displayed with a difference in display time in the order to be read.

  According to the third embodiment, since water is included as a part of the solvent, ferric ions can be generated in the liquid 16 in which the ferric chloride is dissolved. Therefore, it is possible to chemically react with the yellow blood salt in the portion where the yellow blood salt aqueous solution is applied and dried, and to visually develop the portion which is applied and dried with the yellow blood salt aqueous solution. The liquid 16 in which the ferric chloride is dissolved contains an organic compound that is miscible with water and is liquid at room temperature as a part of the solvent. Thus, the time from applying the liquid 16 in which ferric chloride is dissolved to the listable region 14 to drying the solvent containing ferric chloride as a solute is compared with the case where the solvent is water. It can be shortened. Therefore, when the user's fingers and the other sheet-like member 11 come into contact with the surface of the sheet-like member 11, the liquid 16 in which ferric chloride is dissolved infiltrates the user's fingers and the other sheet-like member 11. The potential time can be reduced compared to when the solvent is water.

  Moreover, the magnitude | size of the surface tension of a solvent can be made small by including an organic solvent as a part of solvent. Thereby, when the liquid 16 in which ferric chloride is dissolved is applied to the listable area 14, the speed of infiltration into the listable area 14 can be increased. Therefore, when the user's fingers and the other sheet-like member 11 come into contact with the surface of the sheet-like member 11, the liquid 16 in which ferric chloride is dissolved infiltrates the user's fingers and the other sheet-like member 11. The potential time can be reduced compared to when the solvent is water.

If the recalled rabbit is a Japanese white rabbit, it recognizes that it is a lop ear rabbit by expressing a plurality of designs formed as the yellow blood salt infiltrating region 17. In this way, by drawing a plurality of types or forms of objects represented by the characters 13 written in the listable area 14 as the shapes of the objects, the range of meanings represented by the characters 13 is expanded. be able to. For example, by displaying and educating that the lop ear is also a rabbit, the range belonging to the name rabbit is clearly shown and the concept of the rabbit is promoted more clearly than when educating with a single design. Can do.
