Description

  The present invention relates to a handwriting input board provided with a dot pattern and an information processing system using the handwriting input board.

  Conventionally, a magnetic board using a magnetophoretic display panel is known. In this magnetic board, when the front substrate surface of the magnetophoretic display panel is traced with a magnetic pen, the magnetic particles attracted by the magnetic force of the magnetic pen migrate from the back substrate and reach the front substrate, and the dispersion fluid A black-and-white display is formed by the difference between the contrast between the magnetic particles and the magnetic particles. Color display is also possible by coloring magnetic particles (Patent Document 1).

  In recent years, electronic paper has become widespread. Electronic paper is a display medium that can maintain the visibility and portability, which is an advantage of paper, and can electrically rewrite display contents. When a transparent EL sheet is set on the electronic paper and the user inputs handwriting with a pen, the control unit provided in the operation unit displays the handwriting on the transparent EL sheet based on the handwriting data. Has been proposed. In this handwriting input device, the handwriting is displayed by applying an AC pulse voltage to the transparent electrode at the position of the transparent EL sheet corresponding to the handwriting. When it is detected that the set electronic paper (original) has been changed to another original, the application of the AC pulse voltage is stopped, and all displayed handwriting can be quickly and easily erased. In addition, handwriting data can be stored in the memory of the operation unit (Patent Document 2).

  On the other hand, an expensive handwriting input system is used that can display a handwriting and memorize the handwriting when a touch panel or touch sheet is provided on a display such as a liquid crystal monitor linked with a PC, and the pen is traced with a stylus pen .

  In addition, an input device that can write on a dedicated handwritten input paper printed with a dot pattern with defined XY coordinates with a scanner pen with a writing instrument such as a ballpoint pen and store and transmit the trajectory information with the scanner pen (Patent Documents 3 and 4).

  However, the magnetic board (color drawing toy) of Patent Document 1 cannot leave anything drawn when erasing a picture or a character drawn with a magnetic pen. Therefore, there is a problem that even if it is desired to save what is drawn, this is impossible and lacks flexibility.

  On the other hand, although the handwriting input device of patent document 2 can memorize handwriting data, since a transparent EL sheet is very expensive and a special operation part is required, production of a handwriting input device is possible. However, there is a problem of cost and time.

  In addition, a touch panel that works with a PC has heavy and large drawbacks and is expensive. Recently, Apple's i-pad has appeared, and a thin and light touch panel computer with an area suitable for handwriting input has also appeared, but it is still expensive.

  Furthermore, although the handwriting input devices of Patent Documents 3 and 4 are simple and low-cost, characters and drawings written on a dedicated sheet cannot be quickly erased, and even if they can be erased, traces remain and are confidential. There is a problem that highly specific information and personal information must be disposed of using a shredder or the like.

According to the figure, when a handwriting input board is traced and written with a scanner pen, the written document is visually displayed on the display panel of the handwriting input board. Further, when the user performs a predetermined operation, the document as written is displayed on the display. This is realized by the scanner pen imaging and analyzing the dot pattern on the written locus, and transmitting the analyzed locus information to the computer.

  FIG. 2 is a diagram illustrating the structure of the handwriting input board.

  This handwriting input board is composed of a display panel and an eraser (erasing means). As will be described later in detail, the display panel uses a magnetophoretic display panel or an electrophoretic display panel. The display panel is provided with a dot pattern to be described later.

  The eraser is for erasing a document or a picture written on the display panel. When a magnetophoretic display panel is used, the eraser uses a permanent magnet. Slide the eraser along the back of the display panel. Then, the magnetic particles attracted to the surface of the display panel now migrate to the back surface of the panel, and when viewed from the front side of the panel, only the color of the dispersed fluid is visible, and the display of the document etc. is erased. It will be.

  FIG. 3 is a cross-sectional view showing the tip of the scanner pen. Such a scanner pen has a hollow portion formed therein, a light guide having an opening at the tip thereof, a lens arranged at a position facing the opening of the ride guide, and a lens arranged on the same plane, An LED as a light source that irradiates light of a predetermined wavelength onto the medium surface on which the dot pattern is formed, a C-MOS sensor (optical reading means) disposed at a position retracted from the lens, and a PCB at a position further retracted. And a CPU (not shown) to be installed. The hollow portion of the light guide is formed in a tapered shape having a gradually increasing diameter from the lens toward the opening. Here, the CPU has one or all of the functions of a dot pattern analysis unit, a locus recognition unit, a processing command unit, and an information processing device, which will be described later.

  The light guide is made of transparent or milky white resin, and the inside functions as a light guide. Irradiation light from the LED travels inside the light guide and is irradiated onto the medium from the opening. When the light guide is made of milky white resin, the light emitted from the LED is appropriately diffused as a diffuser when traveling through the light guide, so that the light that irradiates the medium from the opening is made more uniform. Can do.

  The scanner pen may be waterproofed. As a method for waterproofing, the opening at the tip may be closed with a transparent plate (glass or the like), and the other methods may be the same as the waterproofing performed for mobile phones and portable music players having waterproof performance.

  By applying a waterproof treatment, it is possible to provide a strong scanner pen that does not break even if it is wet or placed in a wet location. In addition, information drawn on an underwater communication board often used in scuba diving can be recorded, and the information can be output later on land, so that information can be accurately recorded and enjoyment can be doubled.

  4 to 14 describe the dot pattern 1.

<Description of dot pattern GRID1>
Based on FIGS. 4 to 9, a dot pattern called GRID1 will be described as an example of the dot pattern 1 used in the present embodiment. In these drawings, the grid lines in the vertical and horizontal diagonal directions are given for convenience of explanation and do not exist on the actual printing surface.

  In FIG. 4, the components of the dot pattern 1 and their positional relationships are shown. The dot pattern 1 includes key dots 2, information dots 3, and reference grid point dots 4.

  The dot pattern 1 is generated by arranging fine dots, that is, key dots 2, information dots 3, and reference grid point dots 4 according to a predetermined rule in order to recognize numerical information by a dot code generation algorithm. The

  As shown in FIG. 4, in the block of dot pattern 1 representing information, a 5 × 5 reference grid point dot 4 is arranged with respect to key dot 2 and the center surrounded by four reference grid point dots 4 is arranged. Information dots 3 are arranged around the virtual grid point 5. Arbitrary numerical information is defined in this block. In the example of FIG. 4, a state in which four blocks (inside the thick line frame) of the dot pattern 1 are arranged in parallel is shown. Of course, the dot pattern 1 is not limited to four blocks.

  As shown in FIG. 4, the key dot 2 is a dot in which four reference grid point dots 4 at the corners of the four corners of the block are shifted in a certain direction. The key dot 2 is a representative point of the dot pattern 1 for one block including the information dot 3. For example, the reference grid point dots 4 at the corners of the four corners of the block of the dot pattern 1 are shifted upward by 0.1 mm. However, this numerical value is not limited to this, and can be changed according to the size of the block of the dot pattern 1.

  The deviation of the key dot 2 is preferably about 20% of the lattice interval in order to avoid misidentification with the reference lattice point dot 4 and the information dot 3.

  The information dot 3 is a dot for recognizing various information. The information dot 3 is arranged around the key dot 2 as a representative point, and the center of the grid surrounded by the four reference grid point dots 4 is defined as a virtual grid point 5, It is arranged at the end point represented by the vector as the start point.

  The interval between the information dot 3 and the virtual lattice point 5 surrounded by the four reference lattice point dots 4 is preferably about 15 to 30% of the distance between the adjacent virtual lattice point 5. . This is because if the distance between the information dot 3 and the virtual lattice point 5 is closer than this distance, the dots are easily recognized as a large lump and become unsightly as the dot pattern 1. On the contrary, if the distance between the information dot 3 and the virtual grid point 5 is longer than this interval, the identification of which of the adjacent virtual grid points 5 is the information dot 3 having the vector directionality from the start point is confirmed. This is because it becomes difficult.

When the dot pattern 1 is captured as image data using the sensor unit, the reference grid point dot 4 corrects the lens distortion of the sensor unit, the oblique imaging, the expansion / contraction of the paper surface, the curvature of the medium surface, and the distortion during printing. I can do it. Specifically, a correction function (X _n , Y _n ) = f (X _n ′, Y _n ′) for converting the distorted four reference grid point dots 4 into the original square is obtained, and the same function is obtained. Is used to correct the information dot 3 to obtain a correct vector of information dots 3.

  If the reference lattice point dot 4 is arranged in the dot pattern 1, the image data obtained by capturing the dot pattern 1 with the sensor unit corrects the distortion caused by the sensor unit, so a lens with a high distortion rate is attached. Even when the image data of the dot pattern 1 is captured by the popular sensor unit, the dot arrangement can be recognized accurately. Further, even if the sensor unit is tilted and read with respect to the surface of the dot pattern 1, the dot pattern 1 can be accurately recognized.

  The key dots 2, information dots 3, and reference grid point dots 4 are preferably printed using invisible ink or carbon ink that absorbs infrared light when the sensor unit performs dot reading by infrared irradiation. .

  When a relatively fine dot pattern 1 is printed by a normal ink jet printer or the like, the interval between reference grid point dots 4 (that is, the grid size) may be about 0.5 mm at a minimum. In the case of offset printing, it may be at least about 0.3 mm.

  When the ultra fine dot pattern 1 is formed by using an exposure technique or the like in the semiconductor manufacturing process, the interval between the reference lattice point dots 4 may be about several μm, or finer if a design rule in nm unit is used. It is also possible to form a dot pattern 1 having a dot interval.

  Of course, as long as the interval between the reference grid point dots 4 is equal to or larger than the minimum value, any value may be used depending on the use of the dot pattern 1.

  Further, the diameters of the key dot 2, the information dot 3, and the reference grid point dot 4 are preferably about 10% of the interval between the reference grid point dots 4.

  FIG. 5 shows an example of the information definition method by the information dot 3 arrangement method. These figures are enlarged views showing the position of the information dot 3 and an example of the bit display of information defined by the position.

  In FIG. 5A, the information dot 3 is shifted in distance from the virtual lattice point 5 (for example, 0.1 mm) so as to have a direction and a length expressed by a vector, and rotated clockwise by 45 degrees. An example of a definition method that is arranged in 8 directions and expresses 3-bit information is shown. In this example, since the dot pattern 1 includes 16 information dots 3 per block, 3 bits × 16 pieces = 48 bits of information can be expressed.

  FIG. 5B shows an example of a definition method of the information dot 3 in which the dot pattern 1 has 2-bit information for each lattice. In this example, the information dot 3 is shifted from the virtual lattice point 5 in the plus (+) direction and the oblique (x) direction to define 2-bit information per information dot 3. In this definition method, unlike the definition method shown in FIG. 5A (which can originally define 48-bit information), depending on the application, one block is shifted in the plus (+) direction, and an oblique (× 32 bits (2-bit X16 lattice) data can be provided.

As a combination of the directions in which the information dots 3 arranged in 16 grids included in one block are shifted, a combination of shifting in the plus (+) direction and the diagonal (x) direction for each grid is up to 2 ¹⁶ (about 65000) dot pattern formats can be realized.

  Note that the present invention is not limited to this, and it is possible to represent 4 bits by arranging in 16 directions, and it is needless to say that various changes can be made.

  As shown in FIG. 4, one dot pattern is a dot pattern composed of 4 × 4 block areas, and 2-bit information dots 3 are arranged in each block. FIG. 6 shows the dot code format of this information dot 3.

  As shown in FIG. 6, a parity check, a code value, an X coordinate, and a Y coordinate are recorded in one dot pattern.

  FIG. 7 shows an example of the information definition method based on another arrangement method of the information dots 3. In this definition method, when the information dot 3 is arranged, two types of long and short are used as the shift amount from the virtual lattice point 5 surrounded by the reference lattice point dot 4, and the vector direction is set to eight directions. 16 arrangements can be defined, and 4-bit information can be expressed.

  When this definition method is used, it is desirable that the longer shift amount is about 25 to 30% of the distance between the adjacent virtual lattice points 5, and the shorter shift amount is about 15 to 20%. However, even when the direction in which the long and short information dots 3 are shifted is the same, the center interval of the information dots 3 is separated from the diameter of the information dots 3 so that the information dots 3 can be distinguished and recognized. It is desirable.

  Note that the method of defining 4-bit information is not limited to the above-described definition method, and information bits 3 can be arranged in 16 directions to represent 4 bits, and can be variously changed.

  FIG. 8 shows an example of an information definition method by a method of arranging a plurality of information dots 3 per grid. 8A is an example in which two information dots 3 are arranged, FIG. 8B is an example in which four information dots 3 are arranged, and FIG. 8C is an example in which five information dots 3 are arranged. An example of the arrangement is shown.

The number of information dots 3 per lattice surrounded by the four reference lattice point dots 4 is preferably one in consideration of appearance. However, when it is desired to ignore the appearance and increase the amount of information, a large amount of information can be defined by assigning 1 bit to each vector and expressing the information dot 3 using a plurality of dots. For example, the vector of concentric eight directions, can represent information of one grating per 2 ⁸ can represent 1 information blocks per 2 ¹²⁸ includes 16 grid.

  The dot pattern 1 is recognized by capturing the dot pattern 1 as image data by the sensor unit, first extracting the reference grid point dot 4, and then placing a dot at the position where the reference grid point dot 4 should be. If not, the key dot 2 is extracted, and then the information dot 3 is extracted.

  FIG. 9 shows another arrangement example of the lattice including the information dots 3. FIG. 6A shows an example in which six grids (2 × 3) are arranged in one block, and FIG. 6B shows nine grids (3 × 3) in one block. FIG. 8C shows an example in which 12 grids (3 × 4) are arranged in one block, and FIG. 6D shows 36 grids in one block. This is an example of the arrangement. Thus, in the dot pattern 1, the number of grids included in one block is not limited to 16, but can be variously changed.

  That is, recording can be performed on the dot pattern 1 by adjusting the number of grids included in one block and the number of information dots 3 included in one grid according to the amount of information required or the resolution of the sensor unit. The amount of information can be adjusted flexibly.

<Description of dot pattern GRID5>
FIG. 10 shows another dot pattern example (GRID5).

  FIG. 10A shows the positional relationship between the reference point dots 6a to 6e, the virtual reference points 6f to 6i, and the information dot 3 in the dot pattern.

  The dot pattern defines the direction of the dot pattern according to the shape of the block. In GRID5, first, reference point dots 6a to 6e are arranged. A shape indicating the direction of the block (here, a pentagon facing upward) is defined by a line connecting the reference point dots 6a to 6e in order. Next, based on the arrangement of the reference point dots 6a to 6e, virtual reference points 6f to 6i are defined. Next, a vector having a direction and a length is defined starting from each of the virtual reference points 6f to 6i. Finally, information dot 3 is arranged at the end point of the vector.

  Thus, in GRID5, the direction of the block can be defined by the arrangement method of the reference point dots 6a to 6e. By defining the direction of the block, the size of the entire block is also defined.

  FIG. 2B shows an example in which information is defined depending on whether or not there is an information dot 3 on the virtual reference points 6f to 6i of the block.

  FIG. 2C shows an example in which two GRID5 blocks are connected in the vertical and horizontal directions. However, the direction in which the blocks are connected and arranged is not limited to the vertical and horizontal directions, and may be arranged and connected in any direction.

  In FIG. 10, the reference point dots 6a to 6e and the information dot 3 are all shown as the same shape, but the reference point dots 6a to 6e and the information dot 3 may have different shapes. For example, the reference point dots The dots 6 a to 6 e may have a larger shape than the information dot 3. Further, the reference point dots 6a to 6e and the information dot 3 may have any shape as long as they can be identified, and may be a circle, a triangle, a quadrangle, or a polygon more than that.

<Description of dot pattern Stream dots>
Next, an example of a dot pattern forming method used in the present invention will be described with reference to FIGS.

  11 and 12 sequentially show an example of a process for forming a stream dot pattern.

  The dot pattern according to the present invention is different from the conventional dot pattern. First, in step 1, corresponding to the visible information on the surface of the medium, the reference dot 7 is continuously connected in a line at a position where information is input / output. Place multiple.

  In FIG. 11A, the reference dots 7 are arranged in a curved shape, but the arrangement of the reference dots 7 is not limited to this, and is composed of a straight line and a curved line or a plurality of line segments. Various modifications can be made to form the dot pattern in a shape that matches the area where information is input and output, such as a polygonal line.

  Further, the reference dot 7 may be arranged on a real line visibly formed on the medium surface, or the reference dot 7 may be arranged according to a predetermined rule along the real line. The real line here is a concept with respect to a virtual line, and includes all the lines that actually exist. For example, a solid line, a broken line, a dotted line, a straight line, a curved line, and the like can be mentioned. In the present invention, regardless of the medium on which the line is formed (for example, a display of a video display device) or the substance that forms the line (for example, ink) Absent. In addition, the dot pattern may be unevenness such as printing, display display, or a hole or groove on a metal or plastic.

  In addition, it is desirable to arrange the reference dots at equal intervals from the viewpoint of improving reading accuracy, but the reference dots are not limited to this, and a plurality of intervals are mixed to define a set of constant information of the dot pattern, It is also possible to define both a set of constant information of a dot pattern and a direction of the dot pattern by arrangement intervals of three different reference dots in the set of fixed information.

  Next, as step 2, a first virtual reference line 8 that connects the reference dots 7 arranged in a line is provided. In FIG. 11B, the first virtual reference line 8 is provided by a curved line, but the first virtual reference line 8 is not limited to this, and the reference virtual dots 7 arranged in a curved line are not limited thereto. The straight first virtual reference line 8 may be provided, or the curved first virtual reference line 8 may be provided for the reference dots 7 arranged in a straight line. That is, the second virtual reference line 9, the virtual reference point 10, and the information dot 3 in Step 3 to Step 5 to be described later are arranged according to the positions where the reference dots are connected to each other. One virtual reference line 8 can be freely defined.

  As shown in FIG. 13, the first virtual reference line 8 in the case of a curve is preferably a Bezier curve.

  That is, first, the reference dots 7 on the first virtual reference line 8 are P0 and P3, and P1 and P2 are given control points. Next, points P4, P5, and P6 are obtained by dividing the three line segments P0-P1, P1-P2, and P2-P3 obtained by connecting the control points in order at a one-to-one ratio. Then, points P7 and P8 are obtained by dividing the two line segments P4-P5 and P5-P6 obtained by connecting these points in order at a one-to-one ratio.

  Finally, a point P9 that further divides the line segment connecting the two points, P7-P8, at a ratio of 1: 1 is obtained, and this point becomes a point on the Bezier curve.

  By repeating this procedure, a Bezier curve having control points P0, P1, P2, and P3 is obtained.

  Note that the first virtual reference line 8 may be provided using various algorithms such as a spline curve obtained using a spline function, an nth order polynomial, an elliptic arc, and the like, not limited to a Bezier curve.

  Also, in the second virtual reference line 9, it is possible to define a curve using this method as with the first virtual reference line 8.

  Next, as step 3, a second virtual reference line 9 defined at a predetermined position from the reference dots 7 and / or the first virtual reference line 8 arranged in a line is provided. In FIG. 11C, the second virtual reference line 9 is adjacent to the reference point 7 adjacent to the predetermined position on the vertical line with respect to the tangent line of the first virtual reference line 8 at the midpoint between the adjacent reference dots 7. However, the second virtual reference line 9 is not limited to this, and a virtual reference point is provided in accordance with a region where information is input / output by a dot pattern as will be described later. In addition, it can be defined by various methods.

  In addition, the second virtual reference line 9 may be provided only on one side with respect to the first virtual reference line 8 to define the direction of the dot pattern, or may be provided on both sides to increase the amount of information. .

  Next, as step 4, a plurality of virtual reference points 10 are provided at predetermined positions on the second virtual reference line 9. In FIG. 12A, the virtual reference point 10 is an isosceles triangle whose bottom is the intersection of the second virtual reference lines 9, that is, a straight line connecting adjacent reference dots 7, and the second virtual reference line 9 is the opposite side. However, the position of the virtual reference point 10 is not limited to this, and is provided at the midpoint of the second virtual reference line 9 or instead of the second virtual reference line 9. Various modifications such as provision on the dots 7 are possible.

  In step 5, the information dot 3 is arranged at the end point represented by a vector with the virtual reference point 10 as the start point. In FIG. 12B, one information dot 3 is arranged for one virtual reference point 10 so that the vector direction from the virtual reference point 10 is eight directions and the distance from the virtual reference point 10 is equal. However, the arrangement of the information dots 3 is not limited to this, and the information dots 3 are arranged on the virtual reference point 10, arranged in the vector direction as 16 directions, or two arranged for one virtual reference point 10. It is possible to arrange a plurality of elements in any direction and in any length.

  FIG. 14 is a diagram illustrating an example of a state in which stream dot patterns are arranged in the vertical direction.

  In the figure, in addition to the reference dots and information dots, key dots and side dots are arranged. Key dots are dots arranged at both ends of a set of fixed information. This key dot is a representative point of the dot pattern 1 for one region representing a group of information dots. The side dots are dots arranged on the positive and negative extension lines of the shift of the key dot 2.

  In FIG. 6B, reference dots and stream dot patterns are arranged at equal intervals. In this way, by forming a plurality of stream dot patterns with a fixed reference point interval, XY coordinate values are defined without any gaps in the writing area, and trajectory information can be generated, enabling handwritten input. However, the stream dot pattern according to the present invention is not limited to this, and the interval between the dot patterns may be arbitrarily set as shown in FIG. Also, the interval between the reference dots can be set arbitrarily.

  As a result, the dot pattern in which the XY coordinates are defined is formed in the information area visually formed on the medium surface without being restricted by the shape of the rectangular area when used as a two-dimensional code (used as an index). It is possible to form a dot pattern by repeating a set of constant information in a combined free shape.

  Note that the virtual reference line and the virtual reference point according to the present invention are not actually printed and formed on the surface of the medium, but only when the dot pattern is arranged on the image memory of the computer or when the dot pattern is read. Is set virtually.

  By using this stream dot pattern, it is possible to form a dot pattern on a curved surface body such as a globe, a three-dimensional structure such as a human body model, a three-dimensional map, etc., and the present invention is not limited to a planar map or picture book. It is possible to use the input / output device according to the above.

  FIG. 15 is a diagram for explaining the format of the dot pattern formed on the display panel in the handwriting input board according to the present invention.

  In the figure, the case where the above-described dot pattern of GRID1 is used is described. However, in the present invention, the above-described direction dots, stream dots, and other dot patterns may be used.

As shown in FIG. 15C, the dot pattern is a dot pattern composed of 4 × 4 block regions, and is partitioned into C _{1-0 to} C _31-30 in this block. FIGS. 15A and 15B show the dot code format of each area.

  FIG. 6A shows a format in which display panel codes, X coordinates, and Y coordinates are registered. The display panel code means an ID or the like given to the display panel, and the X coordinate and the Y coordinate each mean a position (coordinate value) on the medium. Accordingly, when the user traces or touches the display panel with the scanner pen, the used display panel and the coordinate position of the read position are simultaneously recognized by one reading operation.

  FIG. 6B shows a format in which a display panel code, an action code, an X coordinate, and a Y coordinate are registered. The action code means an operation instruction. For example, it means operations such as “enlargement” and “reduction” and is included in a dot pattern used mainly in an area other than the writing area.

  Thus, the dot pattern of the present invention can register various code information and XY coordinates such as a display panel code and an action code in one format. In addition, it is possible to register only XY coordinates or only code information, and a flexible format is possible.

  As a method of providing such a dot pattern on the display panel, there are a method using an information input auxiliary sheet, a method of printing directly on the display panel, a method of magnetically or electrically embedding in the display panel, and the like.

<Information input assistance sheet>
FIG. 16 illustrates an information input auxiliary sheet that is one of these methods.

  The information input auxiliary sheet is formed of a transparent film and printed with a dot pattern.

  FIG. 5A shows an information input auxiliary sheet including a dot pattern layer and a transparent sheet / protective layer from the display panel side.

  The dot pattern layer is printed with a dot pattern in which dots made of an infrared absorbing material such as carbon ink are arranged according to a predetermined rule as described above.

  The transparent sheet / protective layer is made of a material that transmits visible light and infrared light, such as vinyl, envipet, and polypropylene. When the dot pattern is repeatedly touched with the scanner, the dots are worn out, causing a problem that the dot pattern cannot be read accurately. Therefore, by providing a transparent sheet / protective layer, it is possible to prevent dots from being worn and soiled and to use the sheet for a long period of time.

  FIG. 2B is an information input auxiliary sheet composed of a transparent sheet, a dot pattern layer, and a protective layer.

  Similar to the protective layer, the transparent sheet is made of a material that transmits visible light and infrared light, such as vinyl, envipet, and polypropylene. Usually, a material that is easy to print is used for the transparent sheet, and a material having high heat resistance and scratch resistance is used for the protective layer.

  FIG. 3C shows an information input auxiliary sheet composed of an infrared reflecting layer, a dot pattern layer, and a transparent sheet / protective layer.

  The infrared reflective layer has a configuration in which an infrared reflective material is vapor-deposited on a transparent sheet for vapor deposition made of a material that transmits visible light, such as vinyl, envipet, and polypropylene. The infrared reflection layer reflects the infrared rays irradiated from the infrared irradiation means of the scanner pen and transmitted through the transparent sheet / protective layer to the scanner pen and transmits visible light. Thereby, only the infrared rays irradiated from the infrared irradiation means of the scanner pen can be used as the irradiation light, and only a bright and clear dot pattern can be photographed, and the dot code can be analyzed accurately.

  FIG. 4D shows an information input auxiliary sheet composed of an infrared diffuse reflection layer, a dot pattern layer, and a transparent sheet / protective layer.

  In the reflection layer that is specularly reflected by the infrared reflection layer, the reflected light is not incident on the lens, so that the center of the imaging region is imaged in a black state, and the dot pattern cannot be completely captured. Therefore, an infrared diffuse reflection layer is provided in place of the infrared reflection layer in FIG. As a result, the infrared light irradiated from the infrared irradiation means is diffusely reflected by the infrared diffuse reflection layer, and the reflected light in a wide photographing area enters the lens.

  FIG. 4E is an information input auxiliary sheet composed of an infrared reflecting layer, an infrared diffusing layer, a dot pattern layer, and a transparent sheet / protective layer.

  The infrared diffusion layer is formed of a transparent or translucent material. The infrared rays irradiated from the infrared irradiation means are specularly reflected by the infrared reflection layer and diffused by the infrared diffusion layer. As a result, when only the infrared reflection layer is used, the reflected light of all photographing regions is more reliably incident on the lens than when the infrared diffuse reflection layer is used.

  Although (b) to (e) are shown as having a gap around the dots of the dot pattern layer, there is actually no gap, and the upper and lower layers are bonded to each other where no dot is arranged. The dot pattern layer in which the dots are arranged is extremely thin.

<Magnetic electrophoresis display panel>
FIG. 17 is a diagram for explaining a magnetophoretic display panel used in the display panel according to the present invention.

  The magnetophoretic display panel has two non-magnetic panels facing each other, and is positioned on the viewing side and the non-viewing side, respectively. A number of partition walls are provided between the panels, and a number of honeycomb cells are formed by the partition walls and the panels.

  Inside the cell, a dispersion fluid composed of magnetic particles, a dispersion medium, a colorant constituting a background portion, and, if desired, a potentiator is enclosed. When the surface of the viewing-side panel is traced with a magnetic pen as shown in FIG. 5A, the magnetic particles are attracted and migrate to reach the back of the viewing-side panel, and the color of the colorant and magnetic particles constituting the background Due to the difference, characters traced with a magnetic pen are displayed on the surface of the panel. Generally, since the magnetic particles have a black or dark brown background color, the colorant constituting the background is set to white so that black-and-white display is performed.

  FIG. 4B is a diagram for explaining a case where characters once displayed are erased. In order to erase characters once displayed, the eraser arranged on the back surface of the non-viewing side panel is slid along the surface of the non-viewing side panel. Then, the magnetic particles attracted to the back side of the viewing side panel migrate to the non-viewing side panel, and when viewed from the viewing side panel side, only the color of the dispersed fluid is visible, and characters and the like are displayed. Is deleted. For the viewing side panel, a non-transparent optical nucleic acid plate such as white is used so that the color of the magnetic particles cannot be seen through from the viewing side when there is no display.

  FIG. 18 is a diagram illustrating a case where a microcapsule magnetophoretic display sheet is used.

  As shown in FIG. 6A, in this embodiment, a large number of spherical microcapsules are accommodated between the viewing side panel and the non-viewing side panel, and a large number of cells are formed by the microcapsules. .

  This microcapsule is composed of a dispersion fluid composed of magnetic particles, a dispersion medium, a colorant constituting a background portion, and a thickening agent as required, and a shell material such as a polymer covering the dispersion fluid.

  When characters or the like are written on the surface of the viewing side panel with a scanner pen, the magnetic particles are attracted along the trajectory to display characters or the like.

  In order to erase characters once displayed, the eraser arranged on the back surface of the non-viewing side panel is slid along the surface of the non-viewing side panel. Then, the magnetic particles attracted to the back surface of the microcapsule on the viewing side panel side migrate in the microcapsule in the direction of the non-viewing side panel and reach the back surface of the microcapsule on the nonviewing side panel side. When viewed from the side panel side, only the color of the dispersed fluid is visible, and the display of characters and the like is deleted.

  When magnetic particles are used as shown in FIGS. 17 and 18, magnetic particles colored with a luminescent material may be used. As the light emitting material, a silicate phosphor, a silicon aluminate phosphor, or the like can be used.

  If you use a luminescent material, the written letters will shine when you shine a little with a flashlight. Therefore, it is possible to read written characters and the like even in a dark place.

<Electrophoretic display panel>
FIG. 19 is a diagram for explaining an electrophoretic display panel used in a display panel according to the present invention.

  In the electrophoretic display panel, a microcapsule electrophoretic sheet is mainly used. In this method, white and black particles are moved by an electric field in a microcapsule containing a fluid to display white and black, which is also called a particle movement type.

  FIG. 4A shows a normal state where no writing is performed. Positive and negatively charged white and black pigment particles are stored together with oil in a transparent microcapsule with a diameter of about 40 μm, and the capsule is arranged in a thin layer between two narrow electrode plates without any gaps. One side of the electrode serving as the display surface is made of a transparent electrode such as ITO (Indium Tin Oxide), and the opposite electrode (lower electrode) is made up of a small rectangular electrode with the required display resolution. Is done.

  FIG. 4B shows a state where writing is performed with the scanner pen. When the user performs writing with the scanner pen, a voltage is applied from an external control circuit. Then, an electric field is generated between the two electrodes, and white and black pigment particles charged positively and negatively migrate in the oil. The pigment particles of the color selected by any voltage (black in the figure) are gathered on the display surface side of the capsule, so that black and white display is performed, and black and white display is selected for each pixel formed by the minute electrodes. It is. Thereby, only the area written by the user is displayed in black.

  FIG. 4C is a diagram for explaining a case where the displayed writing is erased. In order to erase the writing once displayed, the user slides the eraser arranged on the viewing side panel along the surface of the viewing side panel. By sliding the eraser, a voltage opposite to that when writing with the scanner pen is applied, and the white pigment migrates on the surface. Thereby, the writing is erased.

  In addition, although the case where the microcapsule electrophoretic display sheet was used was demonstrated in the same figure, this invention is not limited to this, The electrophoretic display which migrates the positively and negatively charged pigment particle without using a microcapsule A sheet may be used.

<Scanner pen that generates trajectory information>
FIG. 20 is a block diagram illustrating generation of trajectory information using the handwriting input board of the present invention.

  The scanner pen has optical reading means, dot pattern analysis means, trajectory information generation means, storage means, and transmission means.

  When a character or the like is written on the handwriting input board with a scanner pen, the optical reading means of the scanner pen images an XY coordinate on the written locus or a dot pattern in which the XY coordinate and code value are defined. The dot pattern analysis means analyzes the captured dot pattern and outputs XY coordinates or XY coordinates and a code value. Then, the trajectory information generation means generates trajectory information in which the XY coordinates or the XY coordinates and the code value are continuously recorded based on the analyzed dot pattern. The generated trajectory information is stored in the storage unit and / or transmitted to the transmission unit. The transmission means transmits the trajectory information to the information processing apparatus. The storage means and the transmission means may be provided with corresponding buttons, and operation instructions may be given by the buttons.

  Moreover, the handwriting input board has an erasing unit, and when the user completes the writing, the user can erase a part or the whole of the handwriting input board with the eraser.

<Speaking pen>
FIG. 21 is a diagram for explaining a case where a scanner pen (speaking pen) including an audio output unit is used.

  The scanner pen (speaking pen) of the present invention is characterized by having an audio output means in addition to the above-described configuration such as an optical reading means. As shown in the figure, when the user writes “Tokyo Nerima-ku” on the display panel, the dot pattern is imaged by the optical reading means, and the trajectory information based on the XY coordinates output by the dot pattern analyzing means or the XY coordinates Trajectory information is generated by the generating means, characters are recognized by the trajectory information analyzing means, and “Tokyo Nerimaku” and a voice corresponding to the written content are output from the speaking pen.

  FIG. 22 is a diagram for explaining a speaking pen, (a) shows an outline of the speaking pen, and (b) shows a configuration of the speaking pen by a block diagram.

  As shown in the illustrated example, the speaking pen includes a volume adjustment button (−), a volume adjustment button (+), a seesaw button (upper side), a seesaw button (lower side), a push button, a pen tip switch, a microphone, a speaker, It is composed of an LED, a CMOS sensor, FlashROM, Firmware, and MPU.

  The speaking pen can reproduce and record voices, and the main functions are voice reproduction and recording and linking. In the playback function, when the speaking pen reads the dot pattern, the sound is played back with the built-in speaker. The recording function saves the voice recorded with the built-in microphone and links it with the code value defined in the dot pattern. When the user reads the linked dot pattern, the recorded voice can be reproduced by the reproduction function.

  Further, by attaching a pen tip switch to the pen tip, the dot pattern is analyzed only when a printed matter or the like is read, thereby realizing power saving.

  FIG. 23 is a diagram for explaining the analysis of trajectory information in the speaking pen.

  When a character or the like is written on the handwriting input board with a scanner pen, the optical reading means of the scanner pen images a dot pattern on the written locus. The dot pattern analysis means analyzes the captured dot pattern. The trajectory information generating means generates trajectory information based on the analyzed dot pattern. The trajectory information analysis means analyzes the generated trajectory information. The output means outputs sound corresponding to the analysis result.

  Moreover, the handwriting input board has an erasing unit, and the user can erase a part or all of the handwriting input board when the writing is completed.

  The scanner pen of this embodiment is a speaking pen and outputs only sound, but the present invention is not limited to this, and the scanner pen may be provided with a liquid crystal screen or the like to display an image. Moreover, you may enable it to output both an audio | voice and an image.

<Erase means on the scanner pen>
FIG. 24 is a diagram illustrating a case where an erasing unit is provided in the scanner pen.

  In the above embodiment, the erasing means (eraser) is provided on the handwriting input board. However, in the present invention, an eraser may be provided on the scanner pen side as shown in FIG.

  FIG. 4A is a diagram in which an eraser is provided on the opposite side of the optical reading means. In this case, the erased content is erased by pointing the eraser upward at the position corresponding to the writing to be erased on the back side of the handwriting input board. It is particularly suitable for erasing part of the written content. FIG. 5B is a diagram in which an eraser is provided on the abdomen of the scanner pen. In this case, the scanner pen is held sideways and slid on the back side of the display panel to erase the written contents. It is suitable for erasing all written contents at once. FIG. 4C is a diagram in which erasers are provided on both the opposite side of the optical reading means and the abdomen of the scanner pen. By providing both erasers, it is possible to use different erasers depending on whether the written contents are to be partially erased or erased entirely, and the convenience of the user is enhanced.

  FIG. 25 is a diagram for explaining another embodiment of the handwriting input board.

  The figure is a diagram for explaining a handwriting input board provided with an eraser on the back side of a handwriting input board main body frame, wherein (a) illustrates a state in which writing is completed, and (b) illustrates a state in which it is erased. It is.

  A display panel is slidably provided on the handwriting input board of the present embodiment. The display panel has a frame on the left and right, and a handle is provided on the left frame. When erasing the content written on the display panel, the user holds the handle and slides the display panel to the left. Then, the eraser fixed to the back side of the handwriting input board main body erases the written contents.

<Handwriting input board that emits voice>
26 to 29 are diagrams illustrating a handwriting input board that generates sound and transmits trajectory information to the information processing apparatus.

  FIG. 26 is a diagram illustrating a case where sound is generated by a button.

  The handwriting input board of the present embodiment is provided with an eraser fixed as shown in FIG. As shown in FIG. 5A, a button for generating sound is provided on the left side frame of the main body. When the user presses the button, a protrusion comes out from the center of the right end of the left frame of the main body. On the other hand, a protrusion engaging portion is provided on the right frame of the display panel. When the user slides the display panel and the slide is completed, the protrusion fits into the engaging portion. At this time, a collision sound is generated.

  When the collision sound is generated, the voice recognition means built in the scanner pen (not shown) recognizes the collision sound. Then, the transmission means transmits the trajectory information to the information processing apparatus.

  When the user presses the button while the protrusion is protruding, the protrusion is housed in the left frame.

  FIG. 6B is a diagram for explaining a case where a storage button and a transmission button are provided. In the present embodiment, a button 1 described as “memory” and a button 2 described as “send” are provided. Projections corresponding to the respective buttons are provided inside the left frame body, and each projection comes out when each button is pressed. When the user slides the display panel and the slide is completed, the protrusion collides with the engaging portion, and a collision sound is generated. When the projection of the button 1 and the projection of the button 2 collide, collision sounds having different frequencies are generated. The voice recognition means built in the scanner pen (not shown) recognizes the respective voices, and when the collision sound corresponding to the button 1 is recognized, the trajectory information is stored in the storage means of the scanner pen and corresponds to the button 2. When the collision sound to be recognized is recognized, the trajectory information is transmitted from the transmission means to the information processing apparatus.

  FIG. 6C is an enlarged view showing the relationship between the protrusion and the engaging portion when the button is not pressed and when the button is pressed in FIG. When the button is not pressed, the protrusion is stored in the left frame of the handwriting input board body. When the user slides the display panel in this state, the left frame of the main body collides with the right frame of the display panel when the slide is completed. At this time, the protrusion is provided at a position where the protrusion housed in the frame and the engaging portion do not collide to generate a collision sound. Thereby, when the user does not press the button, it is possible to prevent the collision sound from being generated.

  In this embodiment, as in (d), (e), and (f), if the user does not press the button, even if the slide is completed, it engages with the protrusion. The structure which does not generate | occur | produce a collision sound with a part is realizable.

  In this way, by providing a button, if you want to store trajectory information in the scanner pen or send it to the information processing device, generate a collision sound, and if you want to erase the trajectory information as it is without sending it, etc. A selective process of not generating a collision sound can be easily performed. The protrusions may be shaped to engage like a hook as shown in FIG. When the button in (a) is not pressed, the hook does not engage, but in (b), when the button is pressed, the hook-shaped protrusions engage with each other, and when the button is pressed, it slides in contact. Then, when it goes up and meshes, it makes a clicking sound and recognizes the sound. Furthermore, when the finger is released from the button (or when the button is pressed again), the hook-shaped protrusion is released and the slide becomes possible. In order to generate distinctive voices that are easy to distinguish, the generated voices may be provided with a member such as a metal in the hatched portion in the figure. Of course, the hook itself may be a member such as metal that generates distinctive sounds that are easily distinguishable.

  FIG. 27 is a diagram illustrating a case where a button is provided on the right frame of the main body.

  FIG. 4A has one button on the right frame of the main body. In this embodiment, the protrusion protrudes while the button is pressed. When the user releases the button, the protrusion returns.

  The user first deletes the locus by sliding the display panel to the left. When erasing is complete, slide the display panel to the right to return it to its original position. At this time, if the user presses the button, the protrusion and the engaging portion collide, and a collision sound with a predetermined frequency is generated. As a result, the trajectory can be stored or transmitted.

  FIG. 6B is a diagram for explaining a case where a storage button and a transmission button are provided. In the present embodiment, a button 1 described as “memory” and a button 2 described as “send” are provided. Projections corresponding to the respective buttons are provided inside the right frame, and when the respective buttons are pressed, the respective protrusions come out while being pressed.

  Similarly to FIG. 5A, after the user erases the locus, the user slides the display panel to the right to return it to the original position. At this time, the protrusion collides with the engaging portion, and a collision sound is generated. When the projection of the button 1 and the projection of the button 2 collide, collision sounds having different frequencies are generated. The voice recognition means built in the scanner pen (not shown) recognizes the respective voices, and when the collision sound corresponding to the button 1 is recognized, the trajectory information is stored in the storage means of the scanner pen and corresponds to the button 2. When the collision sound to be recognized is recognized, the trajectory information is transmitted from the transmission means to the information processing apparatus. If both buttons are pressed, both the storage of the trajectory information and the transmission to the information processing apparatus are performed.

  FIG. 28 is a diagram illustrating a case where the handwriting input board body has a groove.

  In this embodiment, a button is provided on the right frame of the display panel as shown in FIG. As shown in FIG. 5B, a protrusion is provided on the back side of the button. In addition, a groove is provided in a portion of the main body that is in contact with the upper side of the display panel. A groove may be provided in the protrusion.

  When the user erases the locus, the groove of the main body collides with the protrusion. Then, a collision sound with a predetermined frequency is generated. If the groove provided in the main body is gradually changed in width and depth, the sound (tone) generated while the user slides the display panel also changes gradually. Thereby, the voice recognition means can recognize which area is erased, and instructs the storage means and / or transmission means which area should be stored and / or transmitted.

  Even if the groove provided in the main body has a constant groove width and depth when the display panel is closed, if the button is pressed first, the voice recognition means will continue until the button is released. The target area can be determined by listening to individual sounds.

  When the user presses the button while sliding the display panel, if a projection as shown in FIG. 5C is also made, it is possible to recognize when the display panel is opened and to determine from where the target area is.

  Although illustration is omitted, a protrusion made of a material different from the upper side may be provided on a portion of the main body that contacts the lower side of the display panel. Thus, by determining the audio frequency, the upper button can be used for storage and the lower button can be used for transmission, so that an instruction for storage and / or transmission can be given.

  According to the embodiments of FIGS. 26 to 29, the user can store the trajectory information in the scanner pen or send it to the information processing apparatus only by generating a sound when deleting the trajectory information. It becomes. Therefore, the user can easily transmit necessary trajectory information to the information processing apparatus and save it without performing complicated operations such as pressing a button many times.

  In addition, the locus of the scanner pen is visibly erased, and an operation sound is generated by the operation of the sliding mechanism. Therefore, a voice is generated without using any battery, and the scanner pen recognizes this voice electronically. Since no electronic / electrical mechanism is required on the handwriting input board side, a thin and light handwriting input board can be provided easily and at low cost.

  Note that the present invention is not limited to this, and any method may be used to generate sound as long as the mechanism generates sound, such as an electronic method. Furthermore, an operation instruction may be performed by wireless transmission.

<Information processing system using handwriting input board>
FIG. 30 is a diagram for explaining an information processing system using the handwriting input board of the present invention.

  The information processing system includes a handwriting input board, a scanner pen, and an information processing apparatus.

  The user writes the content corresponding to the desired processing on the handwriting input board using the scanner pen. In this embodiment, “Easy online shopping” is written. Next, the user performs an operation such as pressing a transmission button of the scanner pen or generating a sound when deleting the locus. Thereby, the transmission means of the scanner pen transmits the trajectory information to the information processing apparatus (computer). The computer analyzes the received trajectory information and performs processing corresponding to the analysis result. In the present embodiment, the “Easy Internet Shopping” website is accessed, and the website is displayed on the display. Thus, the user can easily browse the website of online shopping and perform online shopping.

  The present invention is not limited to this, and can be used for executing various instruction commands and inputting / outputting all kinds of information such as access to various websites, distribution of audio and moving images.

  According to this, simply by handwriting an instruction command to be executed or information to be input / output on the handwriting input board, and transmitting the instruction command to the information processing apparatus, the corresponding instruction command is executed and information input / output is performed. . Therefore, the user can perform a desired process with only a thin and light input board and a scanner pen without performing complicated operations such as inputting to the keyboard.

<Thin client system using handwriting input board>
FIG. 31 is a diagram for explaining a thin client system using the handwriting input board of the present invention.

  A thin client is a generic term for a system in which a client terminal used by a user has only a minimum function, and resources such as application software and files are managed on the server side.

  In the present embodiment, a plurality of scanner pens are connected to a single server (information processing apparatus) (not shown) via a network. In addition, a plurality of handwriting input boards are prepared. The server and each scanner pen are connected by a wireless system such as Bluetooth (registered trademark), infrared, or a wired system such as USB.

  When the user writes on the handwriting input board with the scanner pen, the dot pattern on the display panel is read into the scanner pen and converted into XY coordinate values and / or code values in the scanner pen. The XY coordinate value and / or code value is analyzed in the hard disk device of the server, and the locus is recognized based on the XY coordinate value and / or code value. Then, information corresponding to the trajectory is displayed on a projector or display connected to the server.

  Each scanner pen is assigned an ID. When transmitting the XY coordinate value and / or code value of the dot pattern read by the scanner pen to the server, the ID data of the scanner pen is also transmitted at the same time. Then, the server can recognize from which scanner pen the data is transmitted. For example, assume that the user of the scanner pen with ID = 1 has handwritten “Nerima-ku, Tokyo” on the handwriting input board A. Then, the scanner pen with ID = 1 transmits the XY coordinate value and / or code value of the dot pattern and the ID data at the same time. Then, the server recognizes that it has been transmitted from the scanner pen with ID = 1, further analyzes the XY coordinate value and / or code value, and confirms that “Nerima-ku, Tokyo” has been input to the handwriting input board A. recognize. Then, “Nerima-ku, Tokyo” is displayed on the projector. At this time, the fact that it was handwritten by the scanner pen of ID = 1 may be simultaneously displayed on the projector.

  Thus, the handwriting input board of the present invention can also be used in a thin client system. According to this, in conferences such as brainstorming, if attendees bring their own scanner pen and handwriting input board and want to speak, handwriting with the scanner pen will recognize who it is. . Therefore, each attendee does not need to bring a computer, so it is very simple and convenient. In addition, the system can be used for an infinite number of applications such as teacher and student input in school classes, online statements, reception processing, order entry, and equipment management.

<Handwriting input board with icon area>
32 to 34 are diagrams for explaining another embodiment of the display panel.

  (8) Storage + Transmission: The trajectory information to which the index number is added is stored in the storage medium of the scanner pen, and further transmitted from the scanner pen to the information processing apparatus. This icon may be omitted if a storage / send button is provided on the scanner pen side.

  In addition to handwriting input in the writing area, the user can easily perform various operations such as storing the locus in the scanner pen or transmitting it to the information processing apparatus by touching these icons. . Thereby, the convenience of a handwriting input board can be improved further.

  FIG. 4B is a diagram for explaining a dot pattern. FIG. 4C shows a dot code format in the writing area, and FIG. 4D shows a dot code format in the graphic + dot code printing area. FIG.

  As shown in FIG. 5C, dot codes representing X and Y coordinates are registered in the writing area. As a result, the position where the user has written with the scanner pen can be recognized.

  On the other hand, a dot code indicating a code value is registered in the graphic + dot code printing area, as shown in FIG. The code value is a dot code number, and a different dot code number is registered for each icon. For example, in the “3” icon, the dot code number is 3, and in the “stop” icon, the dot code number is 11. As described above, when different dot code numbers are registered, when the user touches the icon with the scanner pen, processing corresponding to the content of the icon is performed.

  FIG. 33 is characterized in that icons used mainly for school tests and entrance examinations are provided. The meaning of each icon is as follows.

  (1) Answer area: Handwritten input area. Handwritten answers to descriptive questions in tests, etc.

  (2) 1 to 30: Check the problem number.

  Further, in the “erasable range A”, all the traces checked can be erased. In the “erasable range B”, it is possible to erase up to the locus where the problem number is checked.

  FIG. 4B is an explanatory diagram showing the format of the dot code printed in the answer area.

  As described above, the answer area is a handwriting input area. In this area, the code No. A, x coordinate, and y coordinate are registered. Code No. A means a handwriting input board ID, that is, an ID assigned to each handwriting input board. Each of the x coordinate and the y coordinate means a position (coordinate value) on the medium. Thus, when the user reads the answer area with the scanner pen, the ID of the handwriting input board and the coordinate position of the read location are simultaneously recognized by one reading operation.

  FIG. 6C is an explanatory diagram showing the format of a dot code printed on each area other than the answer area, that is, each icon such as question number, cancel, and decision.

  In areas other than the answer area, the code No. A and code No. B is registered. Code No. A means a handwriting input board ID, that is, an ID given to each handwriting input board. Code No. B denotes the selection area No, that is, the contents of each icon. For example, a code No. is displayed on the icon “1”. As B, a code meaning “1” is registered. Thus, when the user reads the icon “1”, it is simultaneously recognized by one reading operation that the handwriting input board ID and the problem number “1” are checked.

  Note that the handwriting input board ID may not be provided. Moreover, the format of the dot code of only the selection area No and x and y coordinate values may be used.

  Conventionally, in a test at a school or the like, a question sheet and an answer sheet are distributed to each person who takes the test, so the paper is consumed very much, and there is a problem in the global environment, cost, and confidentiality (leakage of personal information). When the test is performed using the handwriting input board as in the present embodiment, the answer sheet becomes unnecessary, and the paper to be used can be greatly reduced. Moreover, since the scanner pen and handwriting input board can be used repeatedly, it can contribute to the protection of the global environment, maintain confidentiality, and suppress the leakage of personal information.

  Further, highly confidential information such as important meeting results can be quickly erased without being disposed of with a shredder or the like.

For example, when the booklet is a facility inspection report, each page is provided with a writing area for writing the inspection date and time, inspection results, and the like. A dot pattern is printed in this writing area. The user writes necessary information in each writing area and stores it in the scanner pen as needed or transmits it to the information processing apparatus.

  FIG. 4B shows a state in which the page is turned. In this embodiment, the writing area is provided only on one side (back side) of the paper. When the user wants to erase the written content, the user rubs the back surface with an eraser provided separately. If you use a strong magnetic eraser, you can erase what is written on all pages. FIG. 4C is a diagram for explaining the format of the dot code in the writing area. The dot code of each writing area has a code No. B, x coordinate, and y coordinate are registered. Code No. B means a writing area No. A different code No. is registered for each area. Accordingly, when the user performs writing, the scanner pen can recognize in which writing area (for example, “inspection facility name”) the writing is performed.

  FIG. 4D shows a dot code format outside the writing area. B means a selection area No. C means a selection item, and the code No. touched with the scanner pen. Input / output of information and operation instructions corresponding to are executed. Furthermore, a handwriting input board ID may be provided. Of course, the booklet handwritten input board (sheet) is not printed as described above, all pages are writing areas, and a dot pattern in which only IDs and xy coordinates indicating the pages are defined is provided. May be.

  As described above, the handwriting input board according to the present invention can be formed into a booklet. Thereby, it is possible to cope with a case where the inspection report, the business trip report, etc. are desired to be described over a plurality of pages.

  The handwriting input board according to the present invention is an input of teachers and students in school classes, speech on the net, message boards between families, drawing toys for infants, meetings at companies, reception processing, character input to computers It can be used for all purposes such as order entry. In addition to the thin and lightweight handwriting input board, the accessory scanner pen that is light and small enough to fit in the chest pocket can be used, so it is extremely portable and can be used for equipment management and various surveys and reports Can also be used.
