A floppy disk drive for storage, 11 is a printer for printing a document obtained from the document storage means 8, and 12 is an overall control unit for controlling the operation of each component.

With respect to the document creating apparatus constructed as described above, first of all, from the dot pattern stored in the dot pattern storing memory 3, the ruled line is recognized and the coordinates of the start point and the end point of the ruled line on the paper are obtained. The operation of the line recognition means 4 will be described.

FIG. 2 shows an example of dot pattern storage in the dot pattern storage memory 3 in which the dot patterns read by the scanner 1 are stored. As shown in FIG.
“0” or “1” is stored in each dot of the matrix of the dot pattern storage memory 3 according to the black of the corresponding position on the paper read by the scanner 1.
In this example, when the blackness of a certain dot is equal to or larger than a certain threshold value, "1" is stored in this. Further, it is assumed that 3 bits or more of the memory are allocated to 1 dot of the matrix. First, this matrix is sequentially scanned from the top in the X-axis direction to find a series of N or more consecutive "1" stored dots, and the value of these dots is changed from "1" to "2". . When the matrix of FIG. 2 is set to N = 7 and the value is changed according to this method, the dot pattern storage memory 3 becomes as shown in FIG. Next, this matrix is scanned in the Y-axis direction from the left in order to find N or more consecutive dots in which "1" or "2" is stored. If the value of these dots is "1", Is changed to "3", and when the value is "2", it is changed to "4". When the matrix of FIG. 3 is changed to N = 7 and the value is changed according to this method, the dot pattern storage memory 3 becomes as shown in FIG. In FIG. 4, "2" is a dot forming a part of the horizontal ruled line, "3" is a dot forming a part of the vertical ruled line, "4" is a dot which is an intersection of the vertical ruled line and the horizontal ruled line, "1" represents a dot which does not become a part of either the horizontal or vertical stroke, and "0" represents a dot which is not black. Next, the dot pattern storage memory 3 is scanned again from the top in the X-axis direction for each Y coordinate. In each scan, a series of dots having a value of "2" or "4" is searched for, and the coordinates (X2, Y4) at the left end and the coordinates (X9, Y4) at the right end of this series are obtained. It is assumed that this series is recognized as a new horizontal grid line, a horizontal grid line identification number is given, and the horizontal grid line identification number and coordinates (X2, Y4) and (X9, Y4) are stored in the grid line storage means 6. . However,
Suppose that the horizontal scanning line is recognized in the scanning one above,
If the leftmost X coordinate Xhl and the rightmost X coordinate Xhr and X2 and X9 have the relations Xhr ≧ X2 and Xhl ≦ X9, a new horizontal ruled line identification number is not given and The horizontal lines Xhl, Xhr, Y3 recognized in step 2 are updated to X2, X9Y4. However, if Xhl <X2, then Xh
l does not update. If Xhr> X9, Xhr is not updated. In this manner, the dot pattern storage memory 3 is sequentially scanned from the top for each Y coordinate in the X-axis direction, and when the scanning is completed to the bottom, the dot pattern storage memory 3 is again scanned from the top for each Y coordinate. Scan in the X-axis direction. In each scan, look for dots with a value of "3" or "4". If two or more dots with a value of "3" or "4" are consecutive, the coordinates of the left end of these dots (X7
, Y2) and the rightmost coordinate (X8, Y2). If they are not continuous, the coordinates (X3, Y2) of the dot are obtained. Then, it is assumed that these dots are recognized as new vertical ruled lines, the respective vertical ruled line identification numbers are given, and the vertical ruled line identification number and the coordinates (X
7, X8, Y2) and (X3, Y2) are stored. However,
If you recognize the vertical ruled line in the next scan,
If the leftmost X coordinate Xvl and the rightmost X coordinate Xvr and X7 and X8 have a relationship of Xvr≥X7 and Xvl≤X8, a new vertical ruled line identification number is not given and Then, Xvl, Xvr, and Y1 of the vertical ridges recognized in the above are updated. However, if Xhl <X7, Xhl is not updated.
If Xvr> X8, Xvr is not updated.

Scanning the dot pattern storage memory 3 described above, changing the dot value, and storing the recognized identification numbers of the horizontal and vertical lines in the line storage means 6.
The line recognition means 4 stores the coordinates of the start point and the end point in the line storage means 6. In the above example, the scanning of the dot pattern storage memory 3 is divided into the scanning for recognizing the horizontal lane markings and the scanning for recognizing the vertical lane markings. However, these scans should be performed at once. Is also possible.

At the time when all the scans for recognizing the horizontal and vertical lines have been completed, the identification numbers and the starting points of the horizontal and vertical lines recognized from the dot pattern storage memory 3 are stored in the line storage means 6. And the coordinates of the end point are stored.

Next, when the image of the paper is read by the scanner in two or more times, the operation of the identification line number storage means 5 for storing the identification numbers of the identification lines which do not fall within the reading range for one reading will be described. . When the recognition of the horizontal and vertical lines with respect to one reading range by the line recognition means 4 is completed, the line identification number storage means 5
The dot pattern storage memory 3 stores the dot pattern for one column in the lowermost X-axis direction. Further, this one column is scanned to search for a series of dots having a value of "2" or "4". The found sequences are already recognized as horizontal lanes, and the horizontal lane identification numbers correspond to the respective lanes. Therefore, the lane identification number storage means 5 also stores the correspondence between these sequences and the individual horizontal lane numbers. To do. Further, the above-mentioned one column is scanned to search for a series of dots having a value of "3" or "4". The found sequences are already recognized as vertical lanes and the vertical lane identification numbers correspond to the respective lanes, so the lane identification number storage means 5 also stores the correspondence between these lanes and the vertical lane identification numbers. To do. FIG. 5 shows an example of a data structure handled by the line identification number storage means 5. The dot pattern storage memory 51 stores the dot pattern for one column in the lowermost X-axis direction of the dot pattern storage memory 3. In the dot pattern storage memory 52 that forms the horizontal ruled lines and the dot pattern storage memory 53 that forms the vertical ruled lines, in the case where the series or dots or dots found by scanning one row described above are The X coordinate of the start position, the X coordinate of the end position, and the corresponding line identification number are stored.

These pieces of information stored in the grid line identification number storage means 5 are scanned by the grid line recognition means 4 in the X-axis direction row of the uppermost dot pattern in the next reading range and the horizontal grid line and the vertical grid line. Referenced when recognizing a line. The next time the uppermost dot pattern in the reading range is scanned in the X-axis direction, and when a series of dots with a value of "2" or "4" is found, this series is used as a new horizontal ruled line as described above. Although it is recognized, Xhr ′ for the start point X-coordinate Xhl and end point X-coordinate Xhr found in the concatenation storage memory 52 of the dot patterns forming the horizontal lanes of the lane line identification number storage means 5. ≧ Xhl and Xhl ′ ≦ X
If a sequence having Xhl 'and Xhr' in the relation of hr is found, a new horizontal lane identification number is not given and Xhl, Xhr, and Yn of the corresponding recognized horizontal lanes are updated. The same processing is performed when the dot pattern at the top of the reading range is scanned in the X-axis direction to recognize a vertical ruled line.

Next, from the coordinates of the start and end points of the horizontal and vertical lines stored in the line storage means 6,
A line conversion means 7 for converting into line information of the word processor according to the format set in the word processor.
The operation of will be described. The scanning of the image of the paper by the scanner 1 and the processing for recognizing the lanes by the means for recognizing the lanes 4 are alternately repeated once or more, and when the recognition of all the lanes on the paper is completed, the memorizing means 6 is stored in the lane storage means 6. The coordinates of the start and end points of all the recognized horizontal and vertical lines are stored. At this point, a format F is set as a word processor. FIG. 6 shows the parameters set in the format F. In the figure, Dl is the left margin at the time of printing, Dc is the character spacing at the time of printing, Nc is the number of characters in one line, Dt is the upper margin at the time of printing, Dr is the line spacing at the time of printing,
Nr is the number of lines on one page. The rule converting means 7 sets the X coordinates of the starting point and the ending point of the rule to the digit position in the format F, and the Y coordinates of the starting point and the ending point of the rule in the format F.
Convert to the line position in. The conversion method of the X coordinate is Δc = | x−, where x is the X coordinate of the start point or the end point of the rule line.
(Dl + (C-1 / 2) Dc) |, 1 ≦ C ≦ Nc, where C is the digit position where Δc is the minimum. The conversion method of the Y coordinate is as follows: Δr = | y− (Dt + (R−1 / 2) Dr) |, 1 where y is the Y coordinate of the start point or end point of the rule line
R is the digit position such that Δr is minimum in ≦ R ≦ Nr. The rule converting means 7 converts the coordinates of the start point and the end point of one rule stored in the rule storing means 6 into a line position and a column position in the format F by this method, and converts them into two sets of line positions. Get the digit position. Then, the line conversion means 7 changes the document information stored in the document storage means 8 so that a line is drawn between the two sets of line position and column position. The rule converting means 7 performs this process for all the rule lines stored in the rule storing means 6 and changes the document information in the document storing means 8. Finally, the operation of each of the constituent elements 1 to 12 in this example shown in FIG. 1 will be described with reference to the flowchart in FIG.

71. First, the paper feeding unit 2 feeds the paper to a position where the scanner 1 starts reading the paper.

72. Next, the reading of the sheet by the scanner 1 and the sheet feeding by the sheet feeding means 2 are alternately performed.
The read result is converted into a dot pattern and then stored in the dot pattern storage memory 3.

73. Paper reading and paper feeding are repeated until the dot pattern storage memory 3 becomes full. Next, the horizontal line and the vertical line are recognized from the dot pattern stored in the dot pattern storage memory 3 by the line recognition unit 4, and the coordinates of the start point and the end point of each line are stored in the line storage unit 6. Stored in.

74. Next, it is checked whether or not the entire sheet has been read. 75. If it is not finished, the identification number of the scanning line which does not fall within the reading range for one reading and a part of the contents of the dot pattern storage memory 3 are stored by the scanning line identification number storage means 5.

Then, again at 72, the scanner reading is performed. If the entire sheet has been read at 74,
The line converting means 7 converts all the line stored in the line storing means 6 into the line information according to the format on the word processor, and changes the document information stored in the document storing means 8. To do. After that, the contents of the document storage means 8 are displayed on the display device 9, printed by the printer 11, or saved in a floppy disk by the floppy disk drive 10 in accordance with an instruction from the operator.
