  According to the present invention, even though the code pattern is printed using the carbon black ink, the printed dot pattern becomes almost invisible with the naked eye, and characters and pictures printed on the same substrate surface Even if it is overprinted, there is an advantage that the print quality of characters and pictures is hardly deteriorated. Further, since carbon black is used, there is an advantage that an increase in the cost of printed matter can be suppressed.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic overview showing a state in which a printed matter 7 according to the present invention is being read by a pen-type reading and speaking device 1. On the surface of the printed matter 7, a code pattern composed of the first printing elements 3 composed of a plurality of dots is printed. The pen-type reading utterance apparatus 1 irradiates infrared light from the pen tip 11 at the tip thereof, and images and stores reflected infrared light reflected from the first printing element 3 constituting the code pattern. Then, code information of a code pattern is extracted from the captured image, and audio information associated with the code information is reproduced.

  As for the code pattern which consists of the 1st printing element 3 printed on the printed matter 7, the unit code pattern which has the area of a very small area | region is arrange | positioned continuously. Here, the 1st printing element 3 is printed using the black ink which consists of carbon black. Carbon black absorbs visible light as well as infrared light. The pen-type reading and speaking device 1 emits infrared light, and the reflected infrared light is picked up by an image pickup unit such as a CCD. Since carbon black absorbs infrared light, the infrared light is absorbed by the dots constituting the code pattern, and the infrared light is reflected from regions other than the dots. Thereby, the position information of the dots constituting the code pattern is detected, and the code information included in the code pattern is extracted. The pen-type reading and speaking device 1 will be specifically described later.

  FIG. 2 is an enlarged plan view in which the surface of the printed matter 7 according to the present invention is enlarged. A first printing element 3 made of dots constituting a code pattern is printed on the surface of a base material made of paper or the like. X1 to X3 and Y1 to Y3 indicated by broken lines are virtual lines. For example, a unit code pattern is configured by a region A surrounded by virtual lines X1, X2, Y1, and Y2. The unit code pattern includes 16 dots and is printed continuously in the X direction and the Y direction. For example, the unit code pattern is based on a specific dot pattern in contact with the virtual lines X1 and Y1, and the code information is constituted by the positional deviation of each dot with respect to the position defined by the reference dot pattern.

  The unit code pattern area A shown in FIG. 2 has a size of about 1.4 mm square. Each dot has a size of about 0.1 mm square, and the area A contains 16 dots. Therefore, the ratio of the area occupied by the total dots of the unit code pattern composed of the region A is 8.1% with respect to the area of the region A.

  The first printing element 3 having a dot shape is printed with an ink containing about 1.0% by weight of carbon black. Usually, when black printing is performed using carbon black, the carbon black contained in the ink is 20% by weight or more. Accordingly, the first printing element 3 of the printed matter 7 according to the present invention is light black even when viewed with the naked eye.

  By printing the first printing element 3 in this way, for example, when printing on white paper, each dot is hardly visible with the naked eye, and the white color is slightly grayish. Further, even when the dot pattern is printed on the surface on which the second printing element 4 of the color image is printed, the quality of the color image is hardly deteriorated. Accordingly, it is possible to embed a dot pattern as invisible information on a picture holding a vivid color image. In addition, the 2nd printing element 4 which forms a color image is printed with the ink which does not contain carbon black. The printed matter was brought close to the reading unit of the pen-type reading and speaking device 1 and irradiated with infrared light, and the reflected infrared light was imaged to read the code information included in the dot pattern.

  In the unit code pattern shown in FIG. 2, each dot has a quadrangle, but the present invention is not limited to this. Each dot may have a round shape, a polygonal shape, or a star shape. It is only necessary that the position information with respect to the reference dot can be read.

  The dot pattern can be printed by offset printing or gravure printing. When performing offset printing, it is necessary to accurately form the dot code position on the printing plate. Although it is recommended to form by CTP (Computer To Plate) output, it is also possible to make a plate from conventional positive output. In this case, it is sufficient that the plate accuracy can be accurately printed at 150 to 175 lines / inch. This is a precision that is generally used, and it is not necessary to use an advanced printing press or printing plate. Accordingly, the dot size is about 0.08 mm.

  The upper limit of the dot size is about 0.2 mm. If the size of the dot exceeds 0.2 mm, the dot becomes easy to see and the influence on the background pattern and the like becomes large. As described above, the size of the dot is usually about 0.1 mm, but in practice it can be read by the pen-type reading and speaking device 1 even at 0.06 mm. Therefore, the dot size range is 0.06 mm to 0.2 mm.

  The concentration of the ink containing carbon black can be read by the pen-type reading and speaking device 1 from about 0.7% by weight. When the content of carbon black exceeds 2.0% by weight, printed dots are easily visible, and the pattern printed on the periphery and the base is easily affected. The preferable concentration of carbon black that can be stably read by the pen-type reading and speaking device 1 and does not affect the visibility or other patterns is 0.9 wt% to 1.0 wt%. More preferably, it is about 0.95% by weight.

  As a substrate to be printed, art code paper or matte paper is recommended, but is not limited thereto. Materials other than paper such as plastic can be used. When normal paper is used as a substrate for printing, ink after printing may bleed. Since the position information becomes inaccurate when the ink bleeds, it is preferable to use a base material with little ink bleed.

  In the code pattern shown in FIG. 2, the area A of the unit code pattern has a square of 1.4 mm × 1.4 mm, but is not limited to this. The area of the unit code pattern may be a larger area, or may be rectangular or circular. Further, the number of dots included in the unit code pattern area A is not limited to 16. By increasing the number of dots in the area A of the unit code pattern, a lot of code information can be given. In this case, if the number of dots is increased with the area A being constant, the total area of the areas where dots are printed increases with respect to areas where dots are not printed. Since the dots made of the first printing element use ink made of carbon black, when the dot density increases, the dots become dark and can be visually recognized.

Therefore, an ink having a carbon black content of 0.7 wt% to 2.0 wt% is used, and the dot diameter or the size of one side is within a range of 0.06 mm to 0.2 mm, and represents dots. 10 or more (for example, if 1-bit information is given to 1 dot, the number of codes is 2 ¹⁰ = 1024 information, and if 2-bit information is given to 1 dot, the number of codes is ( 2 × 2) ¹⁰ = 1048576 information), by setting the area occupied by the total number of dots within the range of 5% to 33% with respect to the area occupied by the unit code pattern, It was difficult to visually recognize with the naked eye, and it could be read reliably by the pen-type reading and speaking device 1. If the ratio of the area occupied by the total number of dots is less than 5%, the number of dots will be insufficient and the amount of code information will decrease, or the dot diameter will become smaller and it will be difficult to print on a normal printing press or printing plate. . In addition, the printed code pattern cannot be stably read by the pen-type reading and speaking device 1. Furthermore, when the ratio of the area occupied by the total number of dots exceeds 33%, dots printed with the ink containing carbon black can be visually recognized, and the image quality of characters and pictures is deteriorated.

  FIG. 3 shows a plan view of a printed material comprising a pamphlet according to another embodiment of the present invention. A pattern 5 made up of the second printing elements 4 is printed on paper as a substrate. A first printing element 3 made of a code pattern is printed on the entire surface of the picture 5. The second printing element 4 is printed with color ink not containing carbon black. The black color in the second printing element 4 is printed with an ink in which high-density type cyan, magenta, and yellow inks are mixed in an approximately equal weight ratio. That is, the black color of the second printing element 4 does not include carbon black. The first printing element 3 is printed using an ink having a carbon black content of 0.7 wt% to 2.0 wt%. In addition, the dot diameter or the length of one side is in the range of 0.06 mm to 0.2 mm, and the total dot area is 5% to 33% of the area occupied by the unit code pattern. Printed to occupy range. Thereby, the dot pattern which is the 1st printing element 3 can be embedded in a pattern and a character so that it cannot be visually recognized, without reducing the sharpness of the pattern and the character which is the 1st printing element 3.

  The printing can be performed in one process using a five-color machine. Further, printing can be performed using a 4-color machine + 1 color machine. When printing is performed using a 4-color machine + 1 color machine, the dot pattern is printed using a single-color machine. In this case, the second printing element 4 can be printed first by a four-color machine, and the second printing element 4 can be printed later by a one-color machine. Alternatively, the first printing may be printed first using a one-color machine, and the second printing element 4 may be printed using a four-color machine. Since the second printing element 4 transmits infrared rays, the dot pattern of the first printing element 3 can be read even if it is located between the paper surface and the second printing element 4. For black in a four-color machine, ink in which high density cyan, magenta, and yellow are mixed in an approximately equal weight ratio is used.

  When the pen-type reading and speaking device 1 is brought close to the surface of the printed matter and irradiated with infrared light, the second printed element 4 having the dot pattern absorbs infrared light, and the infrared light is reflected in other regions. . The pen-type reading and speaking device 1 captures reflected infrared light, reads code information included in the code pattern, and utters based on the read code information. For example, when the pen-type reading and speaking device 1 is brought close to the printed matter 7 made of a pamphlet shown in FIG. 3 and the reading switch is pressed, the voice is uttered as “This photo is Mt. Fuji seen from Lake Yamanaka”.

  The region occupied by the unit code pattern is a minimal region whose diameter or length of one side is about 1.4 mm, for example. The pen-type reading and speaking device 1 can read the code information if the unit code pattern is continuous in several units. In other words, the code pattern region only needs to have an area of about several square mm. Therefore, if various types of code patterns are printed for each pattern or character area, different information can be embedded for each pattern area.

  For example, in FIG. 3, different code information is printed on the code patterns printed on the cloud part 5a, the sky part 5b, the mountain peak part 5c, the middle part 5d, and the skirt part 5e. Can be granted. The pen-type reading and speaking device 1 is made to approach different areas of the cloud part 5a, the sky part 5b, the mountain peak part 5c, the middle part 5d, and the skirt part 5e to read the code information, thereby producing different sounds. Can be made.

  As the first printing element 3, an ink having a carbon black content of 0.7 wt% to 2.0 wt% is used, and the dot diameter or the length of one side is in the range of 0.06 mm to 0.2 mm. By printing so that the total dot area occupies a range of 5% to 33% with respect to the area of the region occupied by the unit code pattern, the second print element 4 is difficult to visually recognize the code pattern. Does not reduce the sharpness of the pattern and characters. Therefore, it is suitable for brochures and booklets of museums that require the beauty of patterns, and explanatory materials such as museums and aquariums. A code pattern composed of the first printing element 3 is printed on each painting of a pamphlet or booklet of a museum where a large number of paintings are reduced and printed. Further, the pen-type reading and speaking device 1 stores the explanation voice corresponding to the code pattern printed on each picture in association with the code information given to each code pattern. The user can hear audio information about each picture by bringing the pen tip of the pen-type reading and speaking device 1 close to each picture.

  FIG. 4 is a plan view of a printed matter 7 according to another embodiment of the present invention, and shows a state in which the second printing element 4 is printed in accordance with the characters and patterns of the first printing element 3. In FIG. 4, the color and contrast of the mountain top region B and the middle region C covered with snow of the mountain of the pattern printed by the second printing element 4 are different. Similarly, the tree sea region D and middle region C, and the cloud region E and sky region F printed by the second printing element 4 have different colors and contrasts. In this case, a code pattern composed of the first printing element 3 is printed on the entire surface of the peak area B, and code information b is given. A code pattern composed of the first printing elements 3 is not printed in the mountainside area C. In addition, a code pattern consisting of the first printing element 3 is printed on the entire surface of the tree sea area D, and the code information d is given to the cloud area E, and a code pattern consisting of the first printing element 3 is printed on the entire surface of the cloud area E. , Code information e is given. In this way, the first printing element 3 is separated into a printing area and a non-printing area, with the boundary 8 having a different density and color of the second printing element 4 as a boundary. By printing the first print element 3 in this way, the first print element 3 can be made less noticeable.

  FIG. 5 shows a printed matter 7 made of a seal according to another embodiment of the present invention. 5A is a plan view of the printed matter 7, FIG. 5B is a cross-sectional view of the printed matter 7, and FIG. 5C shows a state in which the printed matter 7 is attached to the container-like article 6. FIG. ing. The printed matter 7 is printed with a code pattern made of the first printing elements 3 on the surface of the substrate 2 made of paper or plastic. On the surface of the base material 2, for example, a visually-impaired person touches with a finger or a hand, and is provided with a convex portion that can confirm the attached position. On the back surface of the substrate 2, an adhesive layer 9 made of an adhesive or adhesive that can be attached to another article is formed.

  The printed matter 7 made of this seal is used as follows. For example, the printed material 7 is affixed to an article for daily use. It is often difficult for a visually impaired person to recognize the contents of an article from the shape of the article. In such a case, the location where the printed product 7 is affixed is confirmed by touching the convex portion formed on the printed product 7 with a finger or hand, and the tip of the pen-type reading and speaking device 1 is brought close to that location. Then, the pen-type reading and speaking device 1 reads out the code information from the code pattern printed on the surface of the printed matter 7 and generates a sound corresponding to the code information. For example, the printed material 7 is pasted on the surface of a soy sauce bottle, and a voice “This is soy sauce” is recorded in advance in association with the code pattern of the printed material 7. Infrared light is emitted from the pen-type reading and speaking device 1 to the code pattern of the printed matter 7, code information is read from the reflected infrared light, and sound information corresponding to the read code information is pronounced.

  Also in this case, the first printing element 3 uses an ink having a carbon black content of 0.7 wt% to 2.0 wt%, and the dot diameter or the length of one side is 0.06 mm to 0. If the printing is performed so that the total dot area occupies a range of 5% to 33% with respect to the area of the region occupied by the unit code pattern within the range of .2 mm, the second printing element 4 is included. A code pattern composed of the first printing element 3 can be embedded in a picture or the like.

  In addition, although the convex part 10 was provided in the surface of the base material 2, it may replace with this and may provide a recessed part. Moreover, if the base material 2 and the convex part 10 are formed with a transparent plastic and the 1st printing element 3 which consists of a code pattern is printed on the surface, it will be hard to visually recognize the printed matter 7. FIG. Furthermore, a protective film such as a waterproof film can be formed on the surface of the printed matter 7 so that the first printing element 3 made of the code pattern is not easily peeled off. It becomes possible to affix the printed matter 7 to a place where it is easy to come into contact with other articles such as laundry, or attach it to the article like a tag.

  In addition, when using the printed matter 7 which printed the 1st printing element 3 on the base material 2 which consists of transparent plastics etc. on other articles | goods, the ink containing carbon black is used for the article | item surface of the foundation | substrate of the affixing location. It is desirable that the printed material using is not printed. When the code pattern comprising the first printing element 3 is read by irradiating infrared light, the infrared light passes through the substrate 2 and is influenced by the carbon black printed on the surface of the underlying article. This is because the pattern detection accuracy decreases.

  FIG. 6 shows a learning material for learning acupuncture points and meridians using the printed matter 7 according to the present invention. FIG. 6A shows a human body model 50 engraved with positions of meridians and acupuncture points in the human body, and FIG. 6B shows a partially enlarged view thereof. A meridian 51 and acupuncture points 52 are engraved in the human body model 50. In the vicinity of the acupuncture point 52, a printed matter 7 on which a code pattern made of the first printing element 3 and a name of the acuity point 52 made of the second printing element 4 are printed is attached. Code information is given to the code pattern composed of the first printing elements 3, and the pen-type reading and speaking device 1 stores voice information having a name corresponding to the code information. For example, by confirming the location of the acupuncture point 52 while the visually handicapped person touches with the hand and bringing the pen-type reading and speaking device 1 close to the place, the pen-type reading and speaking device 1 captures the code pattern and extracts code information. Then, the voice information associated with the code information is read out, and for example, “This is Tesanri” is uttered. As a result, a visually handicapped person can learn alone without the help of others.

  Note that the name of the acupuncture point 52 is engraved on the surface of the human body model 50, and the printed matter 7 may be pasted in the vicinity of the concave portion of the acupuncture point 52 or in the vicinity of the engraved name.

  Also here, the first printing element 3 of the printed matter 7 is made of an ink having a carbon black content of 0.7 wt% to 2.0 wt%, and the dot diameter or the length of one side is 0.00. If it is within the range of 06 mm to 0.2 mm, and printing is performed so that the total dot area occupies a range of 5% to 33% with respect to the area of the area occupied by the unit code pattern, it cannot be visually recognized. Code information can be embedded.

  The main program is an image processing program that performs image processing of a code pattern imaged by the imaging unit 36, a code information extraction program that extracts code information from the captured image, and searches for associated audio information based on the code information It consists of a program such as a search program. When the main power switch 27 is turned on, the CPU 40 reads and executes the main program from the ROM 32 to the RAM 41, and realizes an image processing unit, a code information extraction unit, and a voice information search unit, respectively.

  FIG. 9 shows a basic operation flow of the pen-type reading and speaking device 1 according to the present invention. FIG. 9A shows an operation flow in which a specific code pattern printed on a printed material and an input voice are stored in association with each other. FIG. 9B shows an operation flow in which a code pattern printed on a printed material is imaged and audio information associated therewith is reproduced.

  In FIG. 9A, first, the user turns on the main power switch 27 to start the recording / playback mode. The control unit 31 reads out the main program from the ROM 32 and writes it into the RAM 41, and maintains a state waiting for input. The control unit 31 detects that the power / mode switching button 24 is pressed for 3 seconds or more, for example, and sets the recording / playback mode (step S1). The control unit 31 reads out the voice information “recording / playback mode” from the ROM 32, and causes the sound generation unit 18 to pronounce the voice guidance “recording / playback mode” (step S2). The user brings the pen tip 11 of the pen-type reading and speaking device 1 close to the code pattern of the printed matter while pressing the recording button 13.

The control unit 31 temporarily stores the extracted code information in the RAM 41. The control unit 31 detects that the recording button 13 has been released, and issues a specific sound that informs the completion of recording preparation from the sound generation unit 18 (step S6). The user listens to the notification sound and gives an explanation corresponding to the code information to the voice input unit 19 composed of a microphone or the like. The control unit 31 stores the user's voice information collected by the voice input unit 19 (step S7) in the external storage unit 33 in association with the pattern information stored in the RAM 41 (step S8). In this way, the pen-type reading and speaking device 1 stores the code pattern printed on the printed matter and the recorded voice information in association with each other.

  The audio information may be stored in the internal storage unit instead of the external storage unit 33, or may be another external device such as the PC 34 or other external device connected via the USB I / F 38. . In the above embodiment, the user's voice corresponding to the code pattern printed on the printed matter is stored as voice information. Instead, the voice information is stored in advance in a storage element such as a memory card and the memory card is inserted. It may be inserted into the mouth 28 and the detected code information may be associated with the voice information. Also, audio information can be received from the PC 34 via the USB I / F 38 and stored.

  In FIG. 9B, the main power switch 27 is turned on to start the recording / playback mode. The CPU 40 of the control unit 31 reads the main program from the ROM 32, writes it in the RAM 41, executes the program, and maintains a state waiting for input. The control unit 31 detects that the power / mode switching button 24 has been pressed for 3 seconds or longer, and sets the recording / playback mode (step S10). The control unit 31 reads out the audio information from the ROM 32 and causes the sound generation unit 18 to generate a sound guidance “recording / playback mode” (step S11). A user brings the pen tip 11 of the pen-type reading and speaking device 1 close to the code pattern of the printed matter.

  The control unit 31 irradiates infrared light from the infrared light irradiation unit 37 and images the code pattern by the imaging unit 36 (step S12). The control unit 31 temporarily stores the imaging data in the RAM 41 (step S13). The image processing unit reads the image information of the code pattern stored in the RAM 41 and detects processing such as image distortion and dot position information, and the code information extraction unit extracts code information from the dot position information. (Step S13). The voice information search unit searches the voice information stored in the external storage unit 33 based on the extracted code information (step S15). The control unit 31 causes the sound generation unit 18 to sound the sound information searched by the sound information collation unit (step S16). In this way, the pen-type reading and uttering apparatus 1 utters the voice associated with the code information printed on the printed matter.

  In the above embodiment, in the recording mode, the code pattern printed on the printed matter is read to record the voice corresponding to the code pattern, and in the playback mode, the corresponding voice is uttered when the code pattern is read. However, the present invention is not limited to this. For example, voice information associated with a code pattern is stored in the external storage unit 33 in advance, and the pen-type reading and speaking device 1 captures a code pattern printed on a printed matter and extracts the code information from the code pattern. The voice information stored in advance can be searched and pronounced based on the extracted code information.

  The pen-type reading and speaking device 1 includes a USB I / F 38 and can be connected to the PC 34 to input / output voice information, code patterns, and other information. For example, voice information associated with code information may be input from a PC and stored in an external storage unit. Further, the PC can be connected to the network 35, and for example, voice information and other information can be acquired from a server connected to the Internet. Information can be transmitted to a server or the like connected to the Internet via the USB I / F 38. For example, the code information, the Internet URL, and the transmission information are associated with each other and stored in the external storage unit 33, and the pen-type reading and speaking device 1 captures a specific area of the printed matter, whereby the code printed in the specific area is recorded. The code information of the pattern is read out and the associated server is automatically accessed, the voice information is acquired from the server, and the sound generation unit 18 can generate a sound. That is, as the external storage unit 33, a storage unit of the PC 34 or a storage unit of a server connected to the network can be used. In this way, it is possible to generate a large number of types and large volumes of audio information.

  Further, a wired or wireless communication I / F may be provided instead of the USB I / F 38 or together with the USB I / F 38. In this way, network connection is possible without going through the PC 34.

  The case where the printed matter 7 according to the present invention is applied to a pamphlet or a bulletin board of an art museum will be described. For example, the museum pamphlet contains multiple reduced photographs of the paintings exhibited by the museum. Each reduced photograph is formed by the second printing element 4 printed with ink that does not use carbon black. In particular, the black color is printed using an ink in which high density types of cyan, magenta, and yellow are mixed in an approximately equal weight ratio. A code pattern which is the first printing element 3 is overlaid on each reduced photograph. Different code information having different code patterns is assigned to each reduced photograph. As the first printing element 3, an ink having a carbon black content of 0.7 wt% to 2.0 wt% is used, and the dot diameter or the length of one side is in the range of 0.06 mm to 0.2 mm. It is printed so that the total dot area occupies a range of 5% to 33% with respect to the area of the region occupied by the unit code pattern. Therefore, it is difficult to visually recognize the code pattern, and the quality of the reduced photograph is little deteriorated.

  On the other hand, voice information corresponding to the code information is stored in the external storage unit 33 of the pen-type reading and speaking device 1. The user turns on the main power switch 27 of the pen-type reading and speaking device 1 and brings the pen tip 11 closer to the reduced photograph after the sound generation unit 18 utters “Recording / playback mode”. The pen-type reading and uttering apparatus 1 irradiates a reduced photograph with infrared light from the pen tip 11, and images an image of a code pattern printed on the reduced photograph by the imaging unit 36.
