Otherwise, the process proceeds to step S7. In step S6, the portion of the created parenthesis data that covers the editing area 83 is transferred to the VRAM 14 for display.
Proceed to 7.

In step S7, the character being processed is advanced to the next character (if the character being processed is a multi-line bracket code, the character pointer being processed + the code length 62, otherwise the character pointer being processed + 1), and the process proceeds to step S2. Return. Step S10
If the character being processed is over the editing area (the line being processed in the document data 23 is ys and the character position being processed is xs
X1 ≦ xs ≦ x1 + XD and y1 ≦ ys ≦
If y1 + YD), proceed to step S11; otherwise, proceed to step S7. In step S11, the bit map of the character being processed or the outline data is
The character data (image) to be displayed is selected from the ROM 13 and transferred to the VRAM 14 for display.
Proceed to. In step S8, if the current line is the last line (current line = Y), the process ends. If not, the current line is set to the next line and the process returns to step S2.

FIG. 16 is a flowchart of a process of inputting parentheses of a plurality of lines in this embodiment. The input of the multi-line bracket is performed by executing steps S21 to S35. In step S21, the cursor position where the operator has moved the cursor by operating the keyboard 26 or the input position specified by the pen 28 or the like is fetched, and the type of parentheses is given to the operator from the table of FIG. The designated item or the previously selected item is set, and the process proceeds to step S22. In step S22,
The input position determination processing of the multi-line parenthesis in FIG. 17 is performed (the input position of the multi-line parenthesis is determined at one or both of the left and right of the input position), and the process proceeds to step S23.

In step S23, the input positions of all the multi-line parentheses determined in step S22 are determined as shown in FIG.
8 is performed to determine the length of the multi-line parentheses, and step S2 is performed.
Proceed to 4. In step S24, for each of the length candidates for all the input positions of the multi-line parentheses determined in step S23, the characteristic point determination process of the multi-line parenthesis in FIG. 19 is performed, and the process proceeds to step S25. In step S25, if there is a parenthesis input position on the right side of the input position, step S25 is executed.
Among the length candidates on the right side of the input position determined in step 23, the first candidate (the bracket candidate 1 (72) in FIG. 12) is selected, and the process proceeds to step S26.

In step S26, if there is a parenthesis input position on the right side, CG
The bit map and the outline data in the ROM 13 are selected, written in a position in the VRAM 14 corresponding to the right parenthesis input position, and the provisional display 58 of the multi-line parenthesis candidate shown in FIG. Wait, keyboard 2
If there is an OK instruction such as an execution operation performed from step 6 or the like, the process proceeds to step S29, otherwise, to step S2.
Proceed to 7.

In step S27, if there is no right parenthesis input position, or if the operator instructs not to enter parentheses in the right parenthesis input position (by performing a release operation from the keyboard 26 or the like), the flow proceeds to step S30. Proceed, otherwise proceed to step S28. Step S
At 28, the parenthesis candidate is advanced to the next candidate (return to the first candidate if the next candidate does not exist), and the process returns to step S26. In step S29, the multi-line parenthesis information of the selected multi-line parenthesis at the selected input position on the right side is inserted into the address corresponding to the input position on the right side of the document data 23.
Proceed to 30. In step S30, if there is a parenthesis input position to the left of the input position, the first candidate among the length candidates for the left input position determined in step S23 (parenthesis candidate 1 (72) in FIG. 12). A candidate is selected, and the process proceeds to step S31. In step S31, if there is a parenthesis input position on the left side, C
The bit map and the outline data of the GROM 13 are selected, written into the position in the VRAM 14 corresponding to the input position on the left side of the parentheses, and the candidates for the multi-line parentheses are provisionally displayed, and an operator's instruction is waited. If there is an instruction such as OK, the process proceeds to step S34, and if not, the process proceeds to step S32. Step S
At 32, if there is no left parenthesis input position, or if the operator instructs not to enter parentheses at the left parenthesis input position (such as performing a release operation from the keyboard 26 or the like), the process proceeds to step S35. If not, the process proceeds to step S33. In step S33, the parenthesis candidate is advanced to the next candidate (return to the first candidate if there is no next candidate), and the process returns to step S30. In step S34, the multi-line bracket information of the selected multi-line bracket at the selected input position on the left is inserted into the address corresponding to the input position on the left of the document data 23, and the process proceeds to step S35. Step S
At 35, the display processing of FIG. 15 is performed, and the process ends.

FIG. 17 is a flowchart of a process for determining the input position of a multi-line bracket in this embodiment. The input position of the multi-line bracket is determined by executing steps S41 to S53. In step S41, before the input position determination processing for multi-line parentheses is called, FIG.
The process proceeds to step S42 with the input position specified by the cursor 46 or the like in (a) as a reference position. Step S42
Then, the target character is set at the reference position, the character at the reference position is extracted from the document data 23, and the character type (blank character or other) is set as the reference position character type, and the process proceeds to step S43. In step S43, the character of interest is moved right by one character, and the flow advances to step S44.

In step S44, it is checked whether the target character is the end of the sentence (target character position> X).
The process proceeds to step S45 if not. In step S45, it is checked whether the character type of the character of interest is the same as the character type of the reference position.
Otherwise, the process proceeds to step S46. Step S46
Then, the right parenthesis input position is determined to be the position of the target character, and the process proceeds to step S47. In step S47, the position of the target character is returned to the reference position, and the process proceeds to step S48. In step S48, the character of interest is moved one character to the left, and
Go to 49.

In step S49, it is checked whether or not the character of interest is the beginning of the sentence. If it is the beginning of the sentence, the flow proceeds to step S53; otherwise, the flow proceeds to step S50. In step S50, it is checked whether the character type of the target character is the same as the character type at the reference position. If the character type is the same, the process returns to step S48; otherwise, the process proceeds to step S51. In step S51, the left parenthesis input position is determined as the position of the character of interest, and the process ends. Step S5
In step 2, the right parenthesis input position does not exist, and the process proceeds to step S47. In step S53, it is determined that there is no left parenthesis input position, and the process ends. When the parenthesis input position exists on both the left and right sides, two input positions of the parenthesis are determined as shown in FIG. 5, and when there is only an input position on the right side, only one determination position is provided as shown in FIG.

FIG. 18 is a flowchart of the process of determining the length of the parentheses of a plurality of lines in this embodiment. The determination of the length of the multi-line parenthesis and the determination of the length candidate are performed by executing steps S61 to S77. In step S61, the pointer of interest is set to the position of the character to the left of the input position of the multi-line parenthesis set before the length determination processing is executed. Otherwise, the mode is set to the character mode, and the process proceeds to step S62. In step S62, it is determined whether the pointer of interest is on the last line of the page (the row of the pointer of interest =
y1 + YD) Check, if it is the last line of the page, proceed to step S69, otherwise proceed to step S63.

In step S63, the target pointer is moved to the character of the same digit in the next line, and the flow advances to step S64. In step S64, it is checked whether the character type of the character at the position of the pointer of interest is a blank character. If it is a blank character, the process proceeds to step S65; otherwise, the process proceeds to step S67. In step S65, if the set mode is the blank mode, the process returns to step S62; otherwise, the process proceeds to step S66. In step S66, the number of lines -1 from the input position of the multi-line bracket to the position of the pointer of interest is added to the length candidate of the multi-line parenthesis (FIG. 13) (if the target pointer is to the left of the input position, the left length is 76; If it is to the right of the input position, candidates are added from the right length 77), the mode is set to the blank mode, and the process returns to step S62.

In step S67, if the set mode is the character mode, the process returns to step S62; otherwise, the process proceeds to step S68. In step S68, the mode is set to the character mode, and the process returns to step S62. In step S69, if the target pointer has been set and searched for on both sides of the input position of the multi-line bracket, step S
Go to 71, otherwise go to step S70.
In step S70, the target pointer is set to the character on the right side of the multi-line parenthesis input position. If the character type at the target pointer position is a blank character, the mode is set to the blank mode, otherwise the mode is set to the character mode, and the process returns to step S62. .

In step S71, an end code is added to the end of the parenthesis length holding table in FIG. 13, the parenthesis length candidate of interest is set to parenthesis length candidate 1, and the flow advances to step S72. In step S72, the right and left lengths of the parenthesis length candidate of interest are obtained, and the flow advances to step S73. In step 73, the right length obtained in step S72 is compared with the left length, and the right length>
If it is the left length, the process proceeds to step S77; otherwise, the process proceeds to step S74. In step S74, step S7
The right length of the length obtained in step 2 is determined as the length of the parentheses, and the process proceeds to step S75.

In step S75, parenthesis candidate information having the determined length is added to the holding information of the multiple-line parenthesis next candidate in FIG. After adding the flag, the process proceeds to step S76. In step S76, the parenthesis length holding table of FIG. 13 is checked to see if there is a next candidate for the length. If there is a next candidate, the parenthesis length candidate of interest is moved to the next candidate, and the process returns to step S72. To end. In step S77, the left length of the length obtained in step S72 is determined as the length of the parentheses, and the process proceeds to step S75.

FIG. 19 is a flowchart of a process for determining a characteristic point of a multi-line parenthesis in this embodiment. The determination of the characteristic points of the multi-line parentheses is performed by executing steps S81 to S93. In step S81, FIG.
The target candidate is set to the parenthesis candidate 1 (72) of the holding information of the next candidate of the length of the multi-line parenthesis in FIG. 12 with respect to the input position of the multi-line parenthesis passed in step S25 in step S82.
Proceed to. In step S82, it is checked whether the search / setting of the feature point has been completed for all the candidates of the holding information of the next-length parenthesis candidate in FIG. 12. If all candidates have been completed, the process is terminated. If not, the process proceeds to step S83.

In step S83, the state of the direction flag of the target candidate is checked, and if the direction flag is 1 (right open parenthesis), the target character is set to the character on the left side of the input position of the multi-line parenthesis, and the direction flag is set to 2 If it is (left open parenthesis), the target character is set to the character on the right side of the input position of the multi-line parenthesis, and step S8 is performed.
Proceed to 4. In step S84, it is checked whether or not the character type of the target character is a blank character.
Proceed to step 85, otherwise proceed to step S88. In step S85, the character of interest is moved to the character of the same digit in the next line, and the flow advances to step S86. In step S86, if the target character is equal to or longer than the parenthesis length of the target candidate and below the input position of the multi-line parenthesis, the process proceeds to step S87; otherwise, the process returns to step S84.

In step S87, since the position of the feature point cannot be determined in the parentheses of a plurality of lines of interest, the position of the feature point of the interest candidate is set to the center position of the parentheses. The seed may be changed.) The target candidate is moved to the next multiple-line bracket candidate, and the process returns to step S82. In step S88, the position of the character of interest is
And the process proceeds to step S89. In step S89, the character of interest is advanced to the character of the same digit in the next line, and step S89.
Go to 90. In step S90, if the character of interest is located at the position of the parentheses of the input position of the parentheses of a plurality of lines + the candidate of interest + 1 in the line direction, the flow proceeds to step S92; otherwise, the flow proceeds to step S91.

In step S91, it is determined whether or not the character type of the character of interest is a blank character. If it is a blank character, the process proceeds to step S92; otherwise, the process returns to step S89.
In step S92, one line above the position of the character of interest is stored as pointer 2, and the flow advances to step S93. Step S9
In No. 3, pointer 1 and pointer 2
Is set to an intermediate position, and the candidate of interest is moved to the next plural-line bracket candidate, and the process returns to step S92. The various processes in FIGS. 15 to 19 are automatically executed by the CPU 11 shown in FIG.
