Description

Electronic writing apparatus, electronic writing processing program, and recording medium

The present invention relates to an electronic writing apparatus, an electronic writing processing program, and a recording medium for converting writing contents by an operator into electronic data.

A technique for converting electronic data written by an operator using a writing instrument is already known (see, for example, Patent Document 1). In this prior art, when an operator puts a writing medium (paper) and makes a desired description using a writing tool (electronic pen), a plurality of position data of the writing tool moving by the writing operation is acquired. Then, using the acquired plurality of position data, writing data corresponding to the description on the writing medium is generated and temporarily stored. Then, the operator can execute a desired process on the stored writing data by an instruction by filling in the writing medium.

Japanese Patent Laying-Open No. 2014-191662 (paragraphs 0067-0068, FIGS. 11 and 12)

In the prior art, a plurality of filled areas are provided on the writing medium in order to instruct the desired processing. The operator can execute an instruction for the process by painting a plurality of painted areas corresponding to the process intended by the operator. However, if the writing medium is misaligned when the writing medium is held, there is a possibility that the instruction by the filling is erroneously identified. And in order to avoid this, it is necessary to leave the space | intervals between the filling area | regions, and the useless space which cannot be used for original writing on a writing medium becomes wide.

An object of the present invention is to provide an electronic writing apparatus, an electronic writing processing program, and a recording medium that can correctly identify an instruction written by an operator while reducing a necessary space on a writing medium.

In order to achieve the above object, the present invention includes position acquisition means for acquiring a plurality of position data of the writing tool accompanying movement of the writing tool with respect to the writing medium, and the plurality of position data acquired by the position acquisition means. An electronic writing apparatus having stroke data generation means for generating stroke data corresponding to the writing on the writing medium by the writing instrument, wherein the external data is stored in the stroke data generated by the stroke data generation means. A storage unit that temporarily stores writing data corresponding to a target content; a communication unit that transmits the writing data stored in the storage unit by communication in order to store the writing data in an external storage device; and Arranged in a grid of M rows and N columns (M and N are natural numbers) in order to enter an instruction pattern for instructing a desired process Holding means for holding the writing medium on which M × N lattice point regions are formed, and the stroke data generated by the stroke data generating means in a state where the writing medium is held by the holding means Is a passage determination unit that determines in which order the M × N grid point regions of the writing medium have been passed, and the instruction that is written based on the determination result by the passage determination unit Processing determining means for determining the desired processing corresponding to the pattern.

In the electronic writing device of the present invention, the contents written by the operator using the writing tool can be converted into electronic data. That is, when an operator puts a writing medium such as a predetermined paper medium on the holding means and makes a desired description on the writing medium using a writing tool, a plurality of positions of the writing tool moved by the writing operation Data is acquired by the position acquisition means. Then, the stroke data generating means generates writing data corresponding to the description on the writing medium using the plurality of acquired position data. The generated writing data is temporarily stored in the storage means.

Here, in the present invention, a desired process can be executed on the writing data corresponding to the description content stored as described above by an instruction by filling in the writing medium. As an example of this processing, there are storage processing of writing data in an external storage device, distribution processing to a desired storage destination at that time, and the like.

That is, in the writing medium, apart from an area for writing contents corresponding to writing data such as arbitrary characters to be externally stored, a grid for performing a description for instructing the desired processing for the writing data A point area is provided. A total of M × N grid point regions are arranged in a grid of M rows and N columns (M and N are natural numbers) on the writing medium.

When the operator intends to execute the desired process, a plurality of the M × N lattice point areas are passed in a predetermined order in a one-to-one correspondence with the process. The predetermined instruction pattern defined in the above is entered on the writing medium. Thereby, it is determined that the stroke data obtained based on the entry operation has passed through the M × N lattice point regions in the predetermined order by the passage determination unit, and the processing determination unit determines that the stroke data The desired process intended by the operator corresponding to the predetermined instruction pattern is determined.

As described above, in the present invention, the operator performs a desired process on the written data by entering the instruction pattern so as to pass through the lattice point regions arranged in a lattice pattern in a specific order. be able to. Since it is an instruction by pattern entry to connect the grid point areas, even if the writing medium is misaligned during holding by the holding means (by making the grid point area a certain size in advance) There is no effect on the passing / non-passing of the grid point region and the passing order, and the indication pattern can be correctly identified without error.

Further, in particular, in the method of providing a filled area for instructing the desired processing on the writing medium, it is necessary to provide a space between the filling areas in order to avoid misidentification due to the positional deviation of the writing medium. There is a lot of wasted space on the writing medium (cannot be used for original writing). On the other hand, the present invention has an effect of reducing the necessary space on the writing medium by using the method of pattern entry through the lattice point region as described above.

According to the present invention, it is possible to correctly identify an instruction written by an operator while reducing a necessary space on a writing medium.

This “TO DO” instruction pattern is distributed and stored in the “TO DO” folder provided in advance in the server SV when the written data is transmitted to the server SV as described above, as an action content instruction. Instruct to do.

<Detection of instruction pattern>
When the operator fills in the instruction box 74 with the intention of giving each instruction described above, the corresponding stroke data Us is stored in the RAM 203 (for example, distinguished from the writing data of the stroke data corresponding to the written character R). The data is developed on the provided editing buffer, and the CPU 201 detects which one of the instruction patterns U corresponds. FIG. 8 is an explanatory diagram conceptually showing the detection method of the instruction pattern U by the stroke data Us developed on the editing buffer. The indication pattern U is detected by detecting the passing order of the lattice point region P on the lattice detection region W (details will be described later).

First, as shown in FIG. 8A, the stroke data Us corresponding to the instruction pattern U is developed on the editing buffer. After that, as shown in FIG. 8B, the CPU 201 starts to enter the earliest coordinate data of the stroke data Us (that is, the starting end as the left end in the figure) with the electronic pen 3 in the “instruction” box 74. The coordinate data (entry start position data) of the completed entry start position i is specified, and the last coordinate data (that is, the end at the right end in the figure) is completed by the electronic pen 3 in the “instruction” box 74. Is specified as the coordinate data (entry end position data) of the entry end start position j.

Next, as shown in FIG. 8 (c), the CPU 201 uses the specified entry start position data and entry end position data as a reference, and the CPU 201 uses the virtual corresponding to each lattice point area P in the lattice point area PA described above. (For example, small circular) lattice detection area W is set. The 16 grid detection areas W are arranged in a 4 × 4 square grid of 4 × 4 (M = N = 4), and the 16 grid detection areas W constitute a grid detection area WA. . The distance between the vertical and horizontal grid detection areas W of the grid detection area WA is the same as the distance between the vertical and horizontal grid point areas P of the grid point area PA in the “instruction” box 74. As appropriate, each of the 16 grid detection areas W is assigned to “grid detection area A1”, “grid detection area A2”, “grid detection area A3”, and “grid detection” using the column (vertical) and row (horizontal) numbers. "Area A4" "Lattice detection area B1" "Lattice detection area B2" "Lattice detection area B3" "Lattice detection area B4" "Lattice detection area C1" "Lattice detection area C2" "Lattice detection area C3" "Lattice detection area C4" "Lattice detection area D1" "lattice detection area D2" "lattice detection area D3" "lattice detection area D4" and the like.

Then, the CPU 201 detects which of the 16 grid detection areas W set as described above passes through the stroke data Us. In this example, as shown in FIG. 8D, the stroke data Us passes in the order of the grid detection area A1, the grid detection area B4, the grid detection area C2, and the grid detection area D4 (A1 → B4 → C2 → D4). Is detected. As a result, the type of the instruction pattern U corresponding to the stroke data Us (in this example, the “memo” instruction pattern) is specified, and the stroke data of the written character R corresponds to the predetermined type corresponding to the type of the instruction pattern U. Processing (action) is executed.

<Example of action execution>
Examples of actions executed by entering the instruction pattern U as described above are shown in FIGS.

In the example shown in FIG. 9, the operator uses the electronic pen 3 to write characters R (in this example, “8/6” with respect to the paper medium 70 placed on the placement unit 24 using the electronic pen 3. “AM10: 00-A company presentation” and “PM2: 00-tech meeting” are arranged in two upper and lower stages). Then, in the “instruction” box 74, an instruction pattern U (an instruction pattern of “scheduled”) that passes in the order of grid point areas A 2 → B 4 → C 2 → D 4 is entered, and “re” is stored in the “save” box 73. Is checked. Then, writing data (stroke data) corresponding to the written character R is transmitted to the server SV, and the “TODO” folder F1, the “planned” folder F2, the “memo” folder F3, and “others” of the server SV are transmitted. "Folder F4", the "schedule" folder F2 designated by the instruction pattern U is automatically sorted and stored.

Similarly, in the example shown in FIG. 10, the operator uses the electronic pen 3 to write the letter R on the paper medium 70 (in this example, “Company A NDA conclusion” and “Presentation material” above and below two stages). The arranged character string) is described. In the instruction box 74, an instruction pattern U (that is, an instruction pattern of “memo”) that passes through the lattice point areas A1, B4, C2, and D4 in this order is entered, and “re” is stored in the “save” box 73. Is checked. Then, writing data (stroke data) corresponding to the written character R is transmitted to the server SV, and the “TODO” folder F1, the “memo” folder F2, the “planned” folder F3, and “ In the “other” folder F4, the “memo” folder F2 designated by the instruction pattern U is automatically distributed and stored.

<Control flow>
A control procedure executed by the CPU 201 of the electronic writing device 2 to realize the above method will be described with reference to FIG. In FIG. 11, this flow is started, for example, when the power of the electronic writing apparatus 2 is turned on.

In step S10, the CPU 201 performs predetermined initialization (initialization). When step S10 ends, the process proceeds to step S20.

In step S <b> 20, the CPU 201 determines whether or not the coordinate data (position information) of the electronic pen 3 based on the detection result of the coordinate detection unit 25 when the operator has written on the paper medium 70 with the electronic pen 3. Determine. When the coordinate data is acquired, the determination in step S20 is satisfied (S20: YES), and the process proceeds to step S30. If coordinate data has not been acquired, the determination in step S20 is not satisfied (step S20: NO), and the loop waits until the determination in step S20 is satisfied.

In step S30, the CPU 201 generates corresponding stroke data based on the coordinate data acquired in step S20 (stroke data generation processing). When step S30 ends, the process proceeds to step S40. In addition, CPU210 which performs this step S30 functions as a stroke data production | generation means as described in each claim.

In step S40, the CPU 201 expands the generated stroke data in the editing buffer provided in the RAM 203 and temporarily stores it (stroke data storage process). When step S40 ends, the process proceeds to step S50.

In step S50, the CPU 201 checks a check mark “record” in the “save” box 73 provided on the paper medium 70 based on the position data acquired in step S20 and the stroke data generated in step S30 and stored in step S40. "Is written or not. If the “save” box 73 is checked, the determination in step S50 is satisfied (S50: YES), and the action process of step S100 is performed. If the “Save” box 73 is not checked, the determination in Step S50 is not satisfied (Step S50: NO), and the same procedure is repeated by returning to Step S20.

<Action processing>
The procedure of the action process in step S100 will be described with reference to FIG.

First, in step S110, the CPU 201 specifies entry start position data of the stroke data Us developed on the editing buffer of the RAM 203 (see FIG. 8B). When step S110 ends, the process proceeds to step S120.

In step S120, the CPU 201 specifies the entry end position data of the stroke data Us developed on the editing buffer of the RAM 203 (see FIG. 8B). When step S120 ends, the process proceeds to step S130. In addition, CPU210 which performs these step S110 and step S120 as a data specific process functions as a specific means as described in each claim.

In step S130, the CPU 201 sets each virtual lattice detection region W with respect to the stroke data Us based on the entry start position data and entry end position data specified in steps S110 and S120. As described above, each grid detection area W corresponds to each grid point area P provided in the instruction box 74, and in the above example, 16 grid detection areas W are set (see FIG. 8C). ). When step S130 ends, the process proceeds to step S140. The CPU 210 that executes step S130 functions as setting means described in each claim.

In step S140, the CPU 201 detects whether or not the stroke data Us has passed through each grid detection area set in step S130 and the order of passage (if it has passed). In the above-described example using FIG. 8, it is detected that the lattice passes through the lattice detection areas A1, B4, C2, and D4 in this order (see FIG. 8D). When step S140 ends, the process proceeds to step S150. In addition, CPU210 which performs this step S140 and said step S110, step S120 functions as a passage determination means as described in each claim.

In step S150, the CPU 201 refers to the relation table Ts (see FIG. 7) based on the passing order of the grid detection area W detected in step S140, and stroke data (writing data) of the written character R. Determine the action for. In the example described above with reference to FIG. 8, the processing for allocating and storing the writing data corresponding to the written character R to the “memo” folder F2 of the server SV corresponding to the “memo” instruction pattern is determined. When step S150 ends, the process proceeds to step S160. The CPU 210 that executes step S150 functions as a process determination unit described in each claim.

In step S160, the CPU 201 executes the action determined in step S150 on the writing data corresponding to the written character R. In the example described above with reference to FIG. 8, the writing data corresponding to the written character R is transmitted from the electronic writing device 2 to the server SV via the communication control unit 207, and is also stored in the “memo” folder F2 of the server SV. Sorted and stored (see FIG. 10). Thereafter, this routine is terminated.

<Effect of embodiment>
As described above, in the electronic writing apparatus 2 according to the present embodiment, desired processing can be performed on the writing data corresponding to the written character R by an instruction by filling in the paper medium 70. That is, in addition to the free writing area 71 for describing the content (written character R) corresponding to the writing data, the grid point area for performing the description for instructing the desired processing for the writing data on the paper medium 70 P is provided. A total of M × N lattice point regions P are arranged in a lattice pattern of M rows and N columns (M and N are natural numbers) on the writing medium.

When the operator intends to execute the desired process, a plurality of the M × N lattice point areas P are passed in a predetermined order in a one-to-one correspondence with the process. A predetermined instruction pattern U defined in (1) is entered on the paper medium 70. As a result, the CPU 201 determines that the stroke data Us obtained based on the writing operation has passed through the M × N lattice point regions P in the predetermined order (see step S140), and the predetermined instruction The desired process intended by the operator corresponding to the pattern U is determined (see step S150).

As described above, in the present embodiment, the operator fills in the instruction pattern U so as to pass through the lattice point area P arranged in a lattice pattern in a specific order, thereby performing desired processing on the written data. Can be executed. Since it is an instruction by pattern entry that connects the lattice point regions P, even if the paper medium 70 is displaced when held by the mounting unit 24, the lattice point region P is set to a certain size in advance. Therefore, the CPU 201 can correctly identify the instruction pattern U without error, without affecting the passage / non-passage of the lattice point region P and the order of passage. Further, for example, in the conventional method in which a paint area for instructing the desired processing is provided on the paper medium 70, it is necessary to leave a space between the paint areas in order to avoid erroneous identification due to the positional deviation of the paper medium 70. In other words, a useless space (which cannot be used for original writing) on the paper medium 70 becomes wide. On the other hand, in the present embodiment, the space required on the paper medium 70 can be reduced by using the pattern entry method that passes through the lattice point region P as described above. As a result, according to the electronic writing device 2 of the present embodiment, it is possible to correctly identify the instruction written by the operator while reducing the necessary space on the paper medium 70.

In the present embodiment, in particular, based on the stroke data Us generated corresponding to the instruction pattern U, the CPU 201 sets the entry start point Q1 and entry end point Q2 of the instruction pattern U formed in advance on the paper medium 70, respectively. Corresponding entry start position data and entry end position data are specified (see step S110 and step S120). Thereby, the relative positional relationship between the entry start point Q1 and the entry end point Q2 on the paper medium 70, and the relative positional relationship between the coordinate data of the entry start i and the coordinate data of the entry end position j obtained from the stroke data Us. Thus, when the positional deviation occurs, it is possible to detect the deviation amount and the inclination amount of the paper medium 70 at the time of occurrence (refer to a modification described later). Then, by correcting the position data when written in the shifted state using the detected shift amount and tilt amount, the instruction pattern U can be recognized with high accuracy.

In the present embodiment, in particular, the values of M and N described above are the same (in the above example, M = N = 4). As a result, the operator smoothly fills the instruction pattern U with respect to M × N (4 × 4 = 16 in the above example) grid point regions P arranged in the same number of vertical and horizontal grids. Can do.

In addition, it is not restricted to M = N in this way, and it is good also as M <N or M> N. In this case, the entire M × N lattice point regions can be arranged in a vertically or horizontally long space, so that depending on the layout of the paper medium 70, the space where the original writing is performed (free writing region 71) should be as much as possible. Arrangement in a space that does not interfere (for example, a marginal space) is facilitated.

<Modifications>
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described in order.

(1) When the paper medium is held in an inclined state For example, there may occur a case where the paper medium 70 is held in an inclined state on the placement unit 24 for some reason. This modification is an example in the case of detecting the instruction pattern U in the “instruction” box 74 in the paper medium 70 held in such an inclined state. A method for detecting the instruction pattern U in this modification will be described with reference to FIG. 13 corresponding to FIG.

First, as shown in FIG. 13A corresponding to FIG. 8A, the stroke data Us corresponding to the instruction pattern U is developed on the editing buffer. In this example, since the paper medium 70 held on the placement unit 24 is inclined as described above, the stroke data corresponding to the instruction pattern U is entered by filling in the “instruction” box 74 of the inclined paper medium 70. Us is tilted (downward to the right in this example).

Thereafter, as in FIG. 8 (b), as shown in FIG. 13 (b), the earliest coordinate data of the stroke data Us (starting end at the upper left in the figure) is the coordinate data (entry of the entry start position i). The CPU 201 identifies the start coordinate data (start position data), and the last coordinate data (end of the lower right corner in the figure) is identified by the CPU 201 as the coordinate data (entry end position data) of the entry end start position j. At this time, the coordinate data of the entry start position i and the entry end position j is also specified at a position deviated from the original position by the inclination of the stroke data Us.

Thereafter, the positional relationship between the original entry start point position Q1 and entry end point position Q2 of the paper medium 70 without inclination and the positional relationship between the coordinate data of the entry start position i and entry end position j based on the inclined paper medium 70. Based on the above, the CPU 201 calculates the deviation amount (inclination amount) of the stroke data Us. Then, as shown in FIG. 13C, the stroke data Us is corrected by the calculated paper misalignment (inclination) (see arrow).

Then, as described with reference to FIG. 8C, as shown in FIG. 13D, the coordinate data of the entry start position i and the coordinate data of the entry end position j in which the deviation is corrected are used as a reference. Thus, a virtual lattice detection region W corresponding to each lattice point region P of the lattice point region portion PA is set. As described above, 16 grid detection areas W are set in a square grid of 4 rows and 4 columns (M = N = 4).

Thereafter, as in FIG. 8D, as shown in FIG. 13E, the CPU 201 passes the stroke data Us through which of the set 16 grid detection areas W (in this example, the grid detection area). A1 → B4 → C2 → D4). As a result, the type of the instruction pattern U corresponding to the stroke data Us (in this example, the “memo” instruction pattern) is specified, and the corresponding action is executed.

<Control flow>
The main part of the control procedure executed by the CPU 201 of the electronic writing device 2 to realize the above method will be described with reference to FIG. The flow shown in FIG. 14 is different from the flow shown in FIG. 12 in that a new step S125 is added between step S120 and step S130.

In FIG. 14, steps S110 to S120 are the same processing as in FIG. 12, and the description thereof is omitted. When step S120 is completed, the CPU 201 proceeds to a new step S125.

In step S125, the CPU 201 described above with reference to FIG. 13C, the positional relationship between the entry start point position Q1 and entry end point position Q2 of the paper medium 70 without inclination, and the entry start position of the inclined paper medium 70. i. Based on the positional relationship of the coordinate data of the entry end position j, paper misalignment correction processing for correcting the stroke data Us by the misalignment of the paper medium 70 is performed.

<Paper misalignment correction processing>
Details of the paper misalignment correction processing will be described with reference to FIGS. In FIG. 15 to FIG. 17, black circles are lattice points P of theoretical coordinates (that is, coordinates when the paper medium 70 is not inclined), and white circles are real coordinates (that is, the paper medium 70 is inclined). Grid point region P ′ of the coordinates in the case of

1) First, a deviation angle θ between the theoretical coordinate start point Q1 (entry start point) −end point Q2 (entry end point) and actual coordinate start point Q1 ′ (entry start point) −end point Q2 ′ (entry end point) is obtained. .
As shown in FIG. 15, the coordinates of the start point Q1 and the end point Q2 of the theoretical coordinates are expressed as XY coordinates (a, b), (c, d).
The coordinates of the start point Q1 'and the end point Q2' of the real coordinates are expressed as XY coordinates (a ', b'), (c ', d')
Then, the difference between the coordinates of the start point and the end point is
x = ca, y = db
x '= c'-a', y '= d'-b'
It becomes. Then, the deviation angle θ is
θ = tan ⁻¹ (y ′ / x′−y / x) (1)
It becomes.

2) Next, a coordinate shift between the start point Q1 of the theoretical coordinates and the start point Q1 ′ of the real coordinates is calculated.
From the coordinates (a, b) of the start point Q1 of the theoretical coordinates and the coordinates (a ′, b ′) of the start point Q1 ′ of the real coordinates, the difference in coordinates (coordinate deviation) is as shown in FIG.
p = a′−a, q = b′−b (2)
It becomes.

3) Next, as shown in FIG. 17, paying attention to the lattice point area P and the lattice point area P ′ closest to the starting point Q of the theoretical coordinates and the starting point Q1 ′ of the actual coordinates, the center of gravity G (coordinate ( Let Z be the distance from 0,0))) to each of the lattice point regions P, P ′. The shifted actual coordinates are present on the circumference having the center of gravity G of the lattice points and having the distance Z as the radius, and are shifted by the angle θ obtained in 1) above. If the angle from the horizontal line h passing through the center of gravity G to the lattice point area P of the theoretical coordinates is α, the coordinates of the lattice point area P of the theoretical coordinates are
(Zcosα, Zsinα)
It becomes. Therefore, the actual coordinates of the lattice point shifted by α from θ are
(Zcos (α-θ), Zsin (α-θ)) (3)
It becomes.

4) Further, the real coordinates are obtained by taking into account the deviation of the coordinates obtained in the above 2).
The actual coordinates of the equation (3) obtained in the above 3) are (Zcos (α−θ), Zsin (α−θ)), and the coordinate deviation of the equation (2) obtained in the above 2) is p = a′−a , Q = b′−b, the real coordinates of the focused lattice point region P are
(Zcos (α−θ) + p, Zsin (α−θ) + q)
It becomes.

Misalignment detection is possible by performing the same calculation for all the other 15 lattice point regions P. As a result, the stroke data Us can be corrected by the amount of deviation of the paper medium 70 in the paper deviation correction processing in step S125.

Referring back to FIG. 14, steps S130 to S160 are the same as those in FIG. 12, and a description thereof will be omitted.

Also in this modification, the same effect as the above embodiment is obtained. Further, in this modified example, the relative positional relationship between the entry start point Q1 and the entry end point Q2 on the paper medium 70, and the relative position between the entry start position data i and the entry end position data j obtained from the stroke data Us. From the relationship, the shift amount and the tilt amount of the paper medium 70 at the time of occurrence of the positional shift are detected. And since the position data when it is written in the state of deviation is corrected using the detected amount of deviation and inclination, the indication pattern U can be recognized with high accuracy. Furthermore, it is possible to correct the writing data when it is written in the shifted state.

(2) When the size of each grid detection area is increased from the entry start point side to the entry end point side In the above, a plurality of M × N pieces (4 × 4 = 16 in the above example) The grid detection areas W of () have the same size, but the present invention is not limited to this, and the sizes of the grid detection areas can be variably set. That is, a plurality of grid detection areas W may be set so as to gradually increase from the entry start point i toward the entry end point j. Such a modification is shown in FIG.

In FIG. 18A, in this example, the 16 grid detection areas W have the smallest grid detection area A1 closest to the entry start point j (minimum size) and are positioned on the entry end point side of the grid detection area A1. The three grid detection areas C1 and B2 that are the same size and slightly larger (small size) than the grid detection area A1 are located on the entry end point j side of the grid detection areas B1 and A2. , B2, A3 and the four grid detection areas D1, C2, B3, A4 located on the entry end point j side of them, are the same size and slightly larger than the grid detection areas B1, A2 (medium size). ), Three lattice detection regions D2, C3, B4 located on the entry end point i side of the lattice detection regions D1, C2, B3, A4, and lattice detection regions D3, C4 located on the entry end point i side from them They are the same size and slightly larger (large size) than the grid detection areas C1, B2, A3, D1, C2, B3, and A4 and are located on the entry end point i side of the grid detection areas D3 and C4. The grid detection area D4 closest to i is set to be the largest (extra large size).

When the operator enters the instruction pattern U as if writing in a single stroke, for example, the final stage of a single stroke tends to deviate from the original writing position rather than the beginning or middle stage. Therefore, if it is determined based on the same reference for all grid point areas P whether or not they have passed the grid point area P, there is a high possibility that the grid point area P is not passed at the end of the one-stroke writing. .

In this modification, M × N lattice detection areas W are virtually set based on the entry start position data i and entry end position data j specified as described above, and the stroke data Us is detected by the lattice detection. When determining which of the regions W has been passed in what order (the size of the lattice detection region W is not set to a fixed size), the size of the lattice detection region W is increased at the end stage. It is set to be variable. Thereby, it is possible to flexibly cope with the above-described case and to reliably identify the instruction pattern U.

(3) Increasing the size of each grid detection area from the closed side to the open side of the paper medium For example, the spread-note-shaped paper medium 70 may be installed in the placement units 24A and 24B. Assuming that both the left and right pages of the spread form have the paper medium layout of the mode shown in FIG. 5, the page (right page) held on the right mounting portion 24 </ b> A in FIG. The entry start point Q1 side is the closed side of the paper medium 70 (the side close to the hinge C of the placement unit 24), and the entry end point Q2 side is the open side of the paper medium 70 (the side far from the hinge C of the placement unit 24). . In this case, considering the stroke data Us for the 16 grid detection areas W described above, the entry start position i side of the stroke data Us is the closing side of the paper medium 70, and the entry end position j side is the opening side of the paper medium 70. It becomes. In this modification, the lattice detection region W is set so as to gradually increase from the closing side to the opening side of the paper medium 70.

That is, as shown in FIG. 18B, in this example, the 16 lattice detection areas W have four lattice detection areas A1, A2, A3, A4 on the closed side closest to the entry start point j. Four lattice detection regions B1, B2, B3, B4 having the same size and the smallest (small size) and located on the open side of the lattice detection regions A1, A2, A3, A4 are the same size and have the same size. The grid detection areas C1, C2, C3, and C4 that are slightly larger (medium size) than A1, A2, A3, and A4 and located further on the opening side of the grid detection areas B1, B2, B3, and B4 have the same size. Four grid detection areas that are slightly larger (large size) than the grid detection areas B1, B2, B3, and B4, located on the open side of the grid detection areas C1, C2, C3, and C4 and closest to the entry end point j D1 D2, D3, D4 is most increased in the same size to each other (oversize) As has been set.

Also in this modification, as described above, when the operator fills in the instruction pattern U in a single stroke, for example, even if the operator deviates from the entry position to be originally written at the end of the single stroke, Correspondingly, the instruction pattern U can be reliably identified.

(4) When an instruction pattern is pre-printed in the instruction box That is, as shown in FIG. 19, a pattern corresponding to each instruction may be pre-printed in the “instruction” box. In the “instruction” box 74 shown in FIG. 19, the pre-print line Ua corresponding to the “memo” instruction pattern passing in the order of the lattice point area A 1 → B 4 → C 2 → D 4 and the lattice point area A 2 → Corresponds to the pre-print line Ub corresponding to the “scheduled” instruction pattern that passes in the order of B4 → C2 → D4 and the “TO DO” instruction pattern that passes in the order of the grid point areas A1, B2, C3, and D2. The pre-printed line Uc is printed with a broken line in this example. This A times, the operator can give each instruction by writing so as to trace any of these pre-printed lines Ua, Ub, Uc, so the shape (mode) of each instruction pattern is stored. Instructions can be given easily even without them.

(5) When processing is performed at the operation terminal In the above, all the processing shown in the flow of FIG. 12 is performed in the electronic writing apparatus 2, but for example, the operation terminal connected to the electronic writing apparatus 2 so as to be able to transmit and receive information (Appropriate PC, portable terminal, etc.) may acquire stroke data from the electronic writing apparatus 2 and perform the same processing as described above on the acquired stroke data. In this case, the operation terminal includes a buffer similar to the editing buffer of the electronic writing apparatus 2 described above, and the CPU (corresponding to the calculation means) of the operation terminal stores the stroke data received from the electronic writing apparatus 2 in the buffer. expand. After that, the CPU executes a procedure equivalent to step S110 to step S140 in FIG. 12 (corresponding to the passage determination procedure), and after passing through a procedure equivalent to step S150 (corresponding to the process determination procedure), it is equivalent to step S160. The procedure performs the determined action. In this case, a program (electronic writing processing program) for executing such processing is stored in an appropriate recording medium (ROM, EEPROM, etc.) of the operation terminal. In this case, the same effect as described above can be obtained.

In addition, in the above description, when there are descriptions such as “vertical”, “parallel”, and “plane”, the description is not strict. That is, the terms “vertical”, “parallel”, and “plane” are acceptable in design and manufacturing tolerances and errors, and mean “substantially vertical”, “substantially parallel”, and “substantially plane”. .

In addition, in the above description, when there is a description such as “same”, “equal”, “different”, etc., in terms of external dimensions and size, the description is not strict. That is, the terms “identical”, “equal”, and “different” mean that “tolerance and error in manufacturing are allowed in design and that they are“ substantially identical ”,“ substantially equal ”, and“ substantially different ”. .

However, if there is a description of a value that becomes a predetermined judgment criterion or a value that becomes a delimiter, such as a threshold value or a reference value, the “same”, “equal”, “different” etc. It is different and has a strict meaning.

In addition, in the above, the arrow shown in FIG. 2 shows an example of the signal flow, and does not limit the signal flow direction.

Further, the flowcharts shown in FIGS. 11, 12, 14, and 8 do not limit the present invention to the procedure shown in the above-described flow, but add / delete procedures within a range not departing from the gist and technical idea of the invention. Alternatively, the order may be changed.

In addition to those already described above, the methods according to the above-described embodiment and each modification may be used in appropriate combination.

Other than that, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
