Data relating to the start point and end point of the parentheses and the locus of the parentheses are represented by the coordinate origin of the entire document, for example, the X coordinate in the horizontal direction and the Y coordinate in the vertical direction with reference to the upper left position of the document.
[0056]
The trajectory data is composed of a set of pen position coordinates sampled at fixed time intervals.
Then, the parenthesis recognition unit 44 determines which of the parentheses in the parenthesis data table 50b is closest to the shape of the parentheses formed from the set of the locus data, and determines the type of the drawn parentheses. Recognize.
[0057]
The editing unit 42 sends information on the type of parenthesis recognized by the parenthesis recognition unit 44 to the parenthesis generation unit 43, and the parenthesis generation unit 43 generates the information based on the coordinate information of the start point and the end point of the parenthesis. Calculate the size of power brackets and create data for the parentheses to be displayed. The created parenthesis data is stored at a corresponding position in the document information memory 60a.
The above is an outline of the method for inputting parentheses over a plurality of lines. The detailed flow will be described later.
[0058]
Next, FIG. 8 shows a flowchart of the display processing of the generated multi-line parentheses.
In general, the editing unit 42 reads data to be displayed from the document information memory 60a and writes it to the display buffer 60b every time an instruction such as movement of a screen to be displayed is given by an operation from the pen 31, the keyboard 32, or the like. Perform the operation.
Usually, the display control unit 39 displays the display data existing in the display buffer 60b on the CRT 34 in real time.
[0059]
Hereinafter, the flow of FIG. 8 will be described.
In step S1, the position of the page to be displayed corresponding to the position of the document data stored in the document information memory 60a is calculated and stored.
Next, in step S2, a character code for one character is read from the current position in the document data, the character font is transferred from the CGROM 50C to the display buffer 60b, and one character is displayed. Advances the data position by one character.
Next, in step S3, it is checked whether the configuration of the data for one page on the display buffer 60b has been completed. If not completed, the process returns to step S2, and if completed, the process proceeds to step S4.
[0060]
If it is determined in step S4 that the display data creation processing has been performed for all the parentheses, the process ends. If the parenthesis data for which the display data for the parentheses has not yet been created or unchecked remains, step S5 is performed. Proceed to.
[0061]
In step S5, attention is paid to each of the parenthesis data held in the document information memory 60a as the document data, and the parentheses are present in the page for which the display data is currently being created from the position information of the start point and the end point. It is checked whether or not it is, and if it does not exist, it returns to step S4, and if it does, it proceeds to step S6.
[0062]
In step S6, the font data of the corresponding parenthesis is read from the CGROM 50c from the size and type information of the parenthesis for one data of interest, and stored in the display buffer 60b corresponding to the position where the parenthesis should be displayed. The bitmap data is configured, and the process returns to step S4.
[0063]
If the display of a graphic or the like is also performed at the same time, a procedure for transferring the graphic data to the display buffer 60b may be provided without ending the processing in step S4. The same applies to the page configuration procedure when printing is performed. Instead of configuring the display data in the display buffer 60b, the data may be transferred to the printer control unit 38.
[0064]
FIG. 9 illustrates the relationship between the document structure and the position coordinates of the start point and end point over a plurality of lines in the embodiment.
Reference numeral 71 denotes a layout from the first page to the last page of all document data stored in the document information memory 60a; 72, a page boundary; and 73, a bitmap developed on the display buffer 60b and displayed on the CRT 34. Current editing area, 74 is the position of the starting point of the input parenthesis, 75 is the position of the ending point of the input parenthesis, 76 is the number of characters in one line of the document (X), 77 is the total number of lines in the document (Y) , 78 are the number of lines per page (YP) of the document, 79 is the x coordinate (X1) based on the upper left (document origin) of the entire document at the left shoulder (edit origin) of the current editing area, and 80 is the document at the editing origin Y coordinate (Y1) with reference to the origin, 81 is the number of horizontal characters (XD) in the edit area 73, 82 is the number of vertical lines (YD) in the edit area 73, and 83 is the x coordinate of the position of the start point with respect to the edit origin (X1), 84 is based on the editing origin The y coordinate of the position of the start point (y1), 85 is the x-coordinate of the position of the end point relative to the editing origin (x2), 86 is the y coordinate of the position of the end point relative to the editing origin (y2).
[0065]
FIG. 10 shows the structure of parenthesis data stored in the designated parenthesis information memory 60c.
Each input parenthesis has seven data, and all the parenthesis data in the document are arranged by the number of the input parentheses, and an end code 98 indicating that there is no more parenthesis at the end. The data is stored in the RAM 60 in the attached form.
[0066]
Reference numeral 91 denotes the type number of the parentheses shown in FIG. 7, 92 denotes the x coordinate of the starting point based on the document origin of the parentheses, 93 denotes the y coordinate of the starting point based on the document origin of the parentheses, and 94 denotes the document origin of the parenthesis. , 95 is the y coordinate of the end point based on the document origin of the parentheses, 96 is 1 if it is a multi-line parenthesis (vertical bracket) that is long in the vertical direction, and is a multi-character parenthesis that is long in the horizontal direction. If (open parenthesis), a vertical / horizontal flag holding 2 is set, 97 is an open / close flag holding 1 for open parenthesis, and 2 is held for closed parenthesis, and 98 is an end code indicating that there are no more input parentheses.
[0067]
Next, input processing of parentheses over a plurality of lines will be described with reference to FIG.
In step S7, the type number of the parenthesis and its direction (open parenthesis or closing parenthesis) are previously selected or set to default, and the process proceeds to step S8.
In step S8, if the operation of canceling the process is performed by the user, the process ends; otherwise, the process proceeds to step S9.
[0068]
In step S9, the user operates the keyboard 101 to move the cursor 101 or the like, and fetches the position (x1, y1) of the start point of the parentheses over the specified plural lines with respect to the editing origin into the designated parenthesis information memory 60c. (At this time, the cursor moves rightward by one character), and the process proceeds to step S10.
[0069]
In step S10, the start point mark 102 is written at the display position of the display buffer 60b corresponding to the specified start point position (x1, y1), and the display as shown in FIG. 5B is performed, and the process proceeds to step S11. .
[0070]
In step S11, the user performs an operation such as moving the cursor 101 with the keyboard in the same manner as in specifying the position of the start point, and specifies the position (x2, y2) of the end point (x2, y2) of the specified multi-line parenthesis with respect to the editing origin. The data is stored in the memory 60c, and the process proceeds to step S12.
[0071]
In step S12, the end point mark 103 is written at the display position of the display buffer 60b corresponding to the specified end point position (x2, y2), and a display as shown in FIG. 5C is performed, and the process proceeds to step S13. .
In step S13, the positions of the input start point and end point are (x1-x2)²<(Y1-y2)²If so, the process proceeds to step S21 because of the vertical arrangement, and otherwise proceeds to step S14.
[0072]
In step S14, it is determined whether or not the input start point and end point positions are correct. The start point and end point are neither vertically nor horizontally: (x1-x2)²= (Y1-y2)²Or the start point and end point are on different pages: Y1 + y1 <nYP <Y1 + y2 or Y1 + y1> nYP> Y1 + y2 (n: a positive integer), or the start point or end point is out of the layout of the document: x1> X, x2> If X, y1> Y or y2> Y, the process proceeds to step S19 since the input is not correct. If it is determined in step S14 that the input is correct, the process proceeds to step S15.
[0073]
In step S15, the size of the parentheses is calculated from the distance between the start point and the end point, that is, the size of the parentheses is calculated when x1 <x2 = x2-x1, x1> x2, and the process proceeds to step S16. .
In step S16, the size calculated in step S15, the currently set type number, and the parenthesized bitmap data of the direction are called from the CGROM 50c and written by writing them between the start point and the end point of the display buffer 60b. Proceed to S17.
[0074]
In step S17, the user is asked to confirm whether the currently displayed parenthesis is acceptable. If it is, the process proceeds to step S20; otherwise, the process proceeds to step S18.
In step S18, the user is prompted to input the type and direction of the parentheses from an input device such as the keyboard 32, and the parenthesis type number and open / close flag are set in accordance with the input information of the parentheses. Proceed to.
[0075]
In step S19, processing such as sounding the buzzer 46 by controlling the buzzer control unit 47 is performed to inform the user that the input positions of the start point and the end point are inappropriate, and display the start point and end point marks. Then, the process returns to step S7.
[0076]
In step S20, the input parenthesis type 91 shown in FIG. 10, the coordinates (X1 + x1, Y1 + y1) 92 and 93 of the start point based on the text origin, the coordinates (X1 + x2, Y1 + y2) 94 of the end point based on the text origin, and 95, the vertical / horizontal flag 96, and the opening / closing flag 97 of parentheses are added to the end of the parenthesis data of the document data in the document information memory 60a (however, when the vertical parenthesis is y1> y2 or the horizontal parenthesis is x1> x2, the starting point is added The end point and the end point are stored in the storage area of the start point), the end code 98 is added and stored, and the display buffer 60b is erased once. Then, the display processing shown in FIG.
[0077]
In step S21, the size of the parentheses is calculated from the distance between the start point and the end point (when y1 <y2: parenthesis size = y2-y1, when y1> y2: parenthesis size = y1-y2), and the process proceeds to step S22.
In step S22, the size calculated in step S21, the currently set type number, and the parenthesized bitmap data of the direction are called from the CGROM 50c, and displayed by writing between the start point and the end point of the display buffer 60b. Proceed to step S17.
The above input processing is executed by the CPU of the control unit 41 according to the procedure indicated in the control program 50a.
[0078]
Also, regarding the input processing of parentheses over a plurality of lines using the pen 31 in FIG. 6, instead of steps S9 to S12 in the input processing shown in FIG. Is performed.
[0079]
That is, with the initial pen-down position 112 of the pen 31 as a start point and the position 114 where the pen 31 is released as an end point, the shape of the parenthesis drawn by the pen 31 is recognized, and the type, direction, And the position information and the like are set in the designated parenthesis information memory 60c. Thereafter, if the same processing as that shown in FIG. 11 is performed, input processing of parentheses over a plurality of lines using the pen 31 can be performed.
[0080]
The input unit for the start point and the end point can be any unit such as half line, full line, half width, full width, etc. in addition to the character unit. , Image data, and the like.
[0081]
The above is the processing for inputting parentheses over multiple lines. In this way, the start point and the end point for placing parentheses over multiple lines are set, or the shape of parentheses over multiple lines using a pen is set to correspond to the document. Since the user draws directly on the display screen and inputs the start point and end point of the parentheses over a plurality of lines or the trajectory therebetween, the user can easily enter the parentheses over the multiple lines at the intended position.
[0082]
Next, an embodiment of a process for setting and changing the thickness and width of the line segment of parentheses over a plurality of lines will be described.
FIG. 12 shows an example of a display screen for setting the state of parentheses.
Here, the thickness of the parentheses is selected from three types of “thin”, “normal”, and “thick”.
In addition, the thickness of each parenthesis line is assumed to be predetermined, and the parenthesis storage unit 11 stores information on the thickness of each parenthesis along with the type of each parenthesis. .
[0083]
FIG. 13A shows a display example when the thickness of the parentheses is set to “thin”. Regarding the width of the parentheses, it is set how many digits are to be converted into half-width characters or full-width characters. That is, when the width of the parentheses is set to have a width of one full-width character, that is, one digit in FIG. 12, the parentheses having the width as shown in FIG. 13A are displayed.
[0084]
FIG. 13B shows the parentheses of FIG. 13A displayed after the parentheses of FIG. 13A are displayed, and FIG. 13C shows the parentheses of FIG. Is displayed, and the width of the parentheses is changed to three full-width digits.
The information on the thickness and width of the parentheses over a plurality of lines is stored in the designated parenthesis information memory 60c for each parenthesis.
[0085]
Although not described in the data structure of FIG. 10, after setting by the user, information on the thickness stored in the parenthesis data table, for example, a number value “1” indicating “thin” and a value on the width Data, for example, a numerical value (0/1) indicating the distinction between full-width / half-width and the number of digits “3” are stored in the storage location for the parenthesis in the designated parenthesis information memory 60c.
[0086]
Also, instead of displaying the setting screen and changing the thickness and width of the parentheses, by specifying the parentheses to be changed with the cursor and pressing a specific key such as [conversion / next candidate], “ It may be changed in a cycle of “thin” → “normal” → “thick”.
[0087]
Further, when changing the width of the parentheses, as shown in FIG. 14, the start point or the end point of the parentheses may be designated with a pen, and the width of the parentheses may be changed by moving the pen on the screen. This method has an advantage that the width is excellent in visibility and can be set to the width intended by the user, as compared with the case where the width is designated by a numerical value as shown in FIG.
The above is the outline of the processing for changing the thickness and width of the parentheses over a plurality of lines. The operation flow of this processing is shown below.
[0088]
FIG. 15 shows a flowchart of a process for changing the setting of the thickness and width of the parentheses.
The processing described below is performed by the control unit 41 in accordance with the control program 50a, and is actually preferably performed by the CPU.
[0089]
First, before entering this processing, a parenthesis whose setting is to be changed is designated using a cursor.
In step S31, it is monitored whether or not there is an input of a specific key for displaying a screen for setting a parenthesis state shown in FIG. When the input of the specific key is detected, the process proceeds to step S32, and the window screen of FIG.
[0090]
Next, in step S33, the thickness and width are set as described above while the window screen of FIG. 12 is displayed. Here, the set data is not stored in the designated parenthesis information memory 60c, but is temporarily stored in a predetermined area of the setting data memory 60d.
[0091]
In step S34, it is checked whether the setting has been confirmed. For example, it is checked whether the [Execute] key has been pressed. When the [Execute] key has been pressed, in step S35, first, the thickness of the parentheses is changed. Change to the set thickness. This change is performed by rewriting the information value relating to the specified parenthesis thickness in the specified parenthesis information memory 60c.
[0092]
Next, in steps S36 to S41, the width of the parentheses is changed.
In step S36, it is checked whether the current setting of the width of the parentheses is "half-width". This is performed by the control unit 41 determining whether or not the set value of the full-width / half-width character of the specified parenthesis in the specified parenthesis information memory 60c is currently “half-width”.
[0093]
If it is "half-width", the process proceeds to step S37, and it is checked whether the setting data stored in the setting data memory 60d is "half-width".
If the setting is "full-width", the process proceeds to step S38, in which the width is enlarged or reduced by the number of digits of the newly set parenthesis width, and further converted from "half-width" to "full-width". To double. That is, assuming that the current width is a digit and the newly set digit is n digits, the current parenthesis width is multiplied by 2n / a in order to convert from a half-width to a full-width.
[0094]
If the current parenthesis width setting is “full-width” in step S36, the process proceeds to step S39, and it is checked whether the newly set parenthesis width is “full-width”. Here, in the case of "full-width" in step S39 and in the case of "half-width" in step S37, that is, in the case of conversion from "full-width" to "full-width" and in the case of conversion from "half-width" to "half-width" , The process proceeds to step S40, and the width of the parentheses is multiplied by n / a.
[0095]
If the newly set parenthesis width is “half-width” in step S39, the process proceeds to step S41, and the width of the parenthesis is multiplied by n / 2a to change the width from “full-width” to “half-width”.
[0096]
In step S38, step S40, and step S41, specifically, the data relating to the width in the designated parenthesis information memory 60c is rewritten to the new set value.
[0097]
The above is the processing for changing the setting of the thickness and width of the parentheses over a plurality of lines. This makes it possible to further enhance the expressive power of the parentheses over a plurality of lines. The operation of parentheses can be changed by simple operations.
[0098]
Next, a description will be given of a function of creating an opening parenthesis and creating a closing parenthesis by an easy operation when creating a parenthesis over a plurality of lines.
FIG. 16 shows a flowchart of the function for creating the closing parenthesis.
First, in step S51, when the start point of the closing parenthesis is input by the user using the keyboard 32 or the pen 31, the coordinate information of the starting point is stored in the designated parenthesis information memory 60c.
[0099]
Next, in step S52, it is checked by checking the data in the designated parenthesis information memory 60c whether or not there is another parenthesis start point having the same value as the Y coordinate of this start point.
If it does not exist, the process ends. If it does, the process proceeds to step S53, and it is checked whether the parenthesis is an open parenthesis. If it is a closing parenthesis, it is determined in step S57 whether or not parentheses are to be created under the same conditions. If parentheses are to be created under the same conditions, it is determined in step S58 whether or not opening parentheses should be created.
[0100]
When an open parenthesis is created, in step S59, an end point having the same Y coordinate value is determined so as to match the position of the end point of the parenthesis found in step S53, an open parenthesis is created, and a close parenthesis is created. If so, in step S60, an end point is determined to match the position of the end point of the parenthesis similarly found in step S53, and a closing parenthesis is created.
[0101]
If the open parenthesis exists in step S53, the process proceeds to step S54, and the position of the end point of the close parenthesis is obtained.
The position of the end point of the closing parenthesis is determined by the X coordinate value of the starting point input in step S51 and the Y coordinate value of the opening parenthesis found in step S53.
[0102]
Next, in step S55, data on the closing parenthesis is created in the designated parenthesis information memory 60c. That is, data on the coordinate position, type, thickness, width, and the like of the start point and end point of the closing parenthesis are stored in the designated parenthesis information memory 60c.
[0103]
Finally, in step S56, conditions are set for displaying the closing parenthesis, and the process ends.
[0104]
FIG. 17 shows a specific example of the closing parenthesis creation function.
FIG. 17A shows a state in which the starting point of the closing parenthesis is designated by a pen at a position parallel to the already created opening parenthesis.
FIG. 17B shows a state in which the closing parenthesis is created and displayed according to the procedure of FIG. 16 based on the starting point of the closing parenthesis input in FIG. 17A.
[0105]
The above is the processing of inputting the closing parenthesis when the opening parenthesis has already been input.However, since the closing parenthesis is created simply by specifying the start point of the closing parenthesis, the operability of inputting the closing parenthesis is improved. Can be measured.
[0106]
Next, a function of changing the middle point of the parentheses when the parentheses of the type 4 or 5 shown in FIG. 7 are formed on a plurality of lines will be described with reference to FIG.
[0107]
FIG. 19 is a flowchart of the movement of the start point, the middle point, and the end point of parentheses over a plurality of lines.
Here, it is assumed that parentheses over a plurality of lines have already been input and displayed on the CRT 34 in accordance with the flowchart shown in FIG.
In addition, since information on the midpoint is required to move the midpoint, the X and Y coordinates of the midpoint are further stored in the designated parenthesis information memory 60c as shown in FIG. deep. For example, in parenthesis type 4 of FIG. 7 prepared in advance, in the case of a vertical bracket, the X coordinate of the middle point is the same as the X coordinate of the start point and the end point, and the Y coordinate is the center of the start point and the end point.
[0108]
The coordinates of the middle point can be obtained from the coordinates of the start point and the end point of the parentheses by the above-described method when the parentheses over a plurality of lines are created according to the flowchart of FIG. In addition, when creating parentheses over a plurality of lines, the user may be prompted to input the position of the midpoint using a pen or a keyboard.
As described above, when the user inputs the position of the middle point, the position of the middle point of the parentheses over a plurality of lines can be set to a desired position of the user at the time of creation.
[0109]
First, in step S70, it is monitored whether or not an instruction to select a parenthesis over a plurality of lines for which the position of the midpoint is to be changed is issued.
When an instruction to make a selection is given by the pen 31 or the keyboard 32, the process proceeds to step S71, and the cursor is moved to the parentheses on the selected plurality of lines. At this time, when the user designates the middle point and selects the parentheses, the cursor is displayed at the position of the middle point, and when the user designates the start point or the end point, the cursor is moved to the start point or the end point, respectively. Is desirably displayed.
[0110]
Also, when the user's instruction is selected by indicating a position that does not correspond to any of the start point, middle point, and end point, the cursor is displayed at the closest point among these three points, and thereafter, It is also possible for the user to indicate again the point at which the position is to be changed.
[0111]
Next, in step S72, it is monitored whether or not an instruction to change the midpoint from the user, that is, whether or not an input of a position to move the midpoint from the pen or the keyboard is performed. Proceed to S73.
At this time, the position coordinates of the destination are stored in the RAM 60.
[0112]
In the flowchart of FIG. 19, it is determined whether the change instruction is the middle point, the start point, or the end point of the parentheses extending over a plurality of lines in steps S73 and S74. , The process proceeds from step S74 to step S77.
[0113]
In step S77, the position coordinates of the middle point of the parentheses over a plurality of lines are calculated based on the position coordinates of the movement destination of the middle point stored in the RAM 60, and the position of the middle point in the parentheses is determined. The shape of the parentheses is calculated, and the parentheses whose midpoints have been changed are displayed on the CRT.
[0114]
At this time, even when the position coordinates to which the designated middle point is moved are not on the straight line connecting the start point and the end point of the parentheses, the coordinate values are corrected so that the middle point is on this straight line.
This is to prevent the shape of the initial parentheses from being deformed if the designated position is exactly the position of the midpoint.
[0115]
Thereafter, in step S81, it is determined that an input from the user for confirming whether or not the displayed parenthesis is acceptable is made, and if an input is received from the user for confirming, the process proceeds to step S82. , Determine the new parenthesis.
That is, the information about the parenthesis whose middle point has been changed to the position desired by the user is updated. Here, the X and Y coordinates of the midpoint shown in FIG. 20 are updated.
[0116]
FIG. 21 is a diagram for explaining the function of moving the middle point of parentheses over a plurality of lines as described above.
Here, the left diagram of FIG. 21A shows that the middle point at the center between the start point and the end point is indicated by a pen.
The right diagram of FIG. 21A shows that the position to which the designated midpoint is moved is indicated.
FIG. 21B shows the parentheses after the movement is determined.
[0117]
In the right diagram of FIG. 21 (1), even if the instruction to move the midpoint is slightly shifted left and right, the horizontal coordinate of the midpoint is corrected as described above, so that a straight line connecting the start point and the end point is obtained. The middle point can be set at the top, and the deformation of the parentheses can be prevented.
[0118]
The above is the description of the function of moving the middle point of the parentheses over a plurality of lines. However, the position of the start point and the end point of the parentheses can be similarly changed.
In the flowchart of FIG. 19 described above, it is detected in step S72 that the start point or the end point has been selected as the object whose position is to be changed.
[0119]
When the start point is selected, the process proceeds from step S73 to step S75, and a new change position of the start point is calculated to move the start point to the position specified in step S71, and then the start point is determined in step S76. Then, it is displayed on the CRT.
[0120]
If the end point is selected, the process proceeds from step S74 to step S79. Similarly, in steps S79 and S80, a new position of the end point is calculated, fixed, and displayed on the CRT.
[0121]
FIGS. 22 and 23 show an embodiment in which the position of the end point of the parentheses over a plurality of lines is moved.
In FIG. 22, the left diagram of (1) indicates the end point of the parenthesis over a plurality of lines with a pen, and the right diagram of (1) indicates the position to which the end point moves straight down.
FIG. 22 (2) shows the parentheses after the movement is determined.
In FIG. 23, a new coordinate value (X2, Y2 ′) with respect to the initial coordinate value (X2, Y2) of the end point shows a case where the end point is slid in the horizontal direction, and a new coordinate value (X2, Y2). ', Y2 ") shows a case where the end point is moved to an arbitrary position on the CRT screen.
[0122]
That is, by moving the end point or the start point, parentheses extending over a plurality of lines inclined in an oblique direction can be created. As a result, it is possible to easily edit the parentheses that are input once and extend over a plurality of lines. By changing the expressions of the parentheses, it is possible to make the document more legible.
[0123]
The above is a description of the function of moving the start point, the middle point, and the end point of the parentheses over a plurality of lines. However, by applying this function, the parentheses themselves over a plurality of lines can be moved, copied, and deleted.
For example, as shown in FIG. 24, when moving a parenthesis over a plurality of lines, when the parenthesis to be moved is specified by a pen or a keyboard, the coordinate values of the start point, the middle point, and the end point of the parenthesis are stored in the RAM. The coordinates of the start point, the middle point, and the end point may be rewritten to the corresponding coordinate values after the movement, when the position to be moved and thereafter is designated.
[0124]
As described above, since the positions of the start point, the middle point, and the end point of the parentheses over a plurality of lines can be changed, the position, length, and direction of the parentheses once created can be changed by a simple operation.
[0125]
Also, in FIG. 11, the parentheses that are created over a plurality of lines are intended for either vertical parentheses or horizontal parentheses, but need not be limited to this, and are inclined obliquely as shown in FIG. Parentheses may be used.
That is, in the creation of parentheses on a plurality of lines in FIG. 11, the position coordinates are calculated so as to forcibly become vertical brackets or horizontal brackets by judging from the positions of the start point and the end point input by the user. If the parentheses are created using the positions of the start point and the end point input by the user as they are, the parentheses extending over a plurality of slanted lines can be created.
[0126]
Note that when inputting the start point and end point of the parentheses with a pen, it is difficult to input the start point and end point accurately in the vertical or horizontal direction, so that the input is normally performed as shown in FIG. When it is necessary to make it possible to create vertical brackets or horizontal brackets, and to create oblique parentheses, it is preferable to first input, for example, an instruction to enter a mode for creating oblique parentheses.
[0127]
Next, the rotation of the parentheses over a plurality of lines created in the present invention will be described.
As shown in FIG. 26, this function is to rotate the parenthesis about a middle point or an arbitrary point on the parenthesis over a plurality of lines that have already been created. Hereinafter, an arbitrary point on the parenthesis serving as the rotation center of the parenthesis is referred to as a reference point.
[0128]
FIG. 27 shows a schematic flowchart in one embodiment of this rotation function.
First, in step S90, it is monitored whether or not the user has performed an input for executing the rotation function. If the input has been performed, the process proceeds to step S91. In step S91, it is determined whether or not there is an input indicating a reference point serving as a rotation center of parentheses over a plurality of lines that the user wants to rotate.
The input of the reference point may be performed by moving the cursor with a pen or a keyboard.
[0129]
The reference point does not need to be limited to the middle point of the parentheses, and the designated point may be set as the reference point. However, it is difficult to specify the midpoint accurately, such as when inputting with a pen, but if you want to specify the midpoint as the reference point, simply specify any point in the brackets you want to rotate, and the reference point will , It is preferable to forcibly set the middle point of the parentheses.
[0130]
Next, in step S92, the input rotation angle is stored in the RAM, and in step S43, the input rotation direction is stored in the RAM.
If the input angle and direction are not correct in step S93, some error display is performed in step S99.
[0131]
When the input angle and direction are correct, in step S95, it is determined whether there is a confirmation input for checking whether there is an error in the input setting. If the confirmation input is made, the process proceeds to step S96, and the rotation is performed. A calculation is performed on the display position of the parenthesis later. Here, for example, the position coordinates after rotation of the start point, the middle point, and the end point shown in FIG. 20 are obtained by coordinate conversion or the like.
[0132]
In step S97, parentheses after rotation obtained by the above calculation are displayed.
The above is the function of rotating parentheses over a plurality of lines in the present invention. With this, it is possible to easily create parentheses over a plurality of lines with expressive power, and thus to create a more legible document.
[0133]
Next, in the present invention, an editing function such as moving, copying or erasing of a plurality of overlapping parentheses will be described.
As shown in FIG. 28, in the case where parentheses are displayed on a CRT over a plurality of overlapping lines, the parentheses can be separately edited.
[0134]
Here, a case is shown in which the parentheses A and B of two overlapping plural lines are selected and moved. Generally, when the user designates an overlap point, that is, the end point of parenthesis A and the start point of parenthesis B, as shown in FIG. 28, it cannot be determined whether parenthesis A or parenthesis B has been designated. Therefore, the order in which these parentheses are created is stored, and when such an overlapping point is specified, the parentheses are selected in the order in which the parentheses were created.
[0135]
By doing so, the parentheses created first are selected, but if this is not the desired parenthesis, the input operation of a specific key for sequentially selecting the created parentheses is performed in the parentheses. May be repeated until is selected.
It is preferable that the selected parenthesis be displayed in a blinking manner so as to be distinguished from other parentheses.
Then, by performing the above-described functions such as moving, copying, rotating, or erasing the selected parentheses over a plurality of lines, even if the parentheses over a plurality of lines are overlapped, one by one is separately provided. Can be edited.
[0136]
In addition, information as shown in FIG. 20 is created for each of the parentheses over a plurality of overlapping lines. However, in addition to the information shown here in order to execute the editing function of the overlapping parentheses described above, It is necessary to memorize the number indicating the order of creation for each parenthesis.
In this way, overlapping parentheses that overlap each other can be handled separately, and parentheses over a plurality of lines at the time of document creation can be edited more easily.
[0137]
【The invention's effect】
According to the present invention, the position of the start point and the end point of the specified parenthesis is set, or the user is caused to input the shape of the parenthesis by handwriting at a desired position and recognize the position. You can easily enter parentheses that span multiple lines of the intended size.
In addition, since the position, thickness and width of the parentheses can be set, the thickness or width of the parentheses can be changed by a simple input operation even after the parentheses are once generated. Once created, the expression in parentheses can be changed so that the document is easy to read with a simple operation.
[00138]
In addition, the position, length, and direction of the parentheses once created can be changed by a simple operation by indicating the positions to change the start point, middle point, and end point of the parentheses over a plurality of lines. Since the parentheses can be rotated, it is possible to easily create parentheses over a plurality of lines with expressive power, and thus to create an easy-to-read document.
Further, according to the present invention, when the opening parenthesis has already been input, the closing parenthesis is created simply by indicating the start point of the closing parenthesis, so that the operability of inputting the closing parenthesis can be improved.
