Abstract

PURPOSE:To efficiently and extractly designate a fixedly unified character string. CONSTITUTION:Internal data for edit is comprised of a command equipped with at least the level information of a command used in the designation of a character string and character information equipped with at least the level information of a character similarly used in the designation of the character string. When the fixedly unified character string targeted for edit is designated, the level information A of the character where a cursor is located is compared first with the level information B of the command appearing first at the front of the character by searching the internal data (S4). When coincidence is obtained between them, a front command is searched (S2), and when noncoincidence is obtained, the character immediately after the command is set as the start character S of the character string targeted for edit (S5). Thence, the command with the same level as that of the command just before the start character S is searched to the rear (S6), and the character just before the command is set as the end character E of the character string targeted for edit(S7). All the characters from the start character S to the end character E of the character string are selected as edit targets.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character input / editing device, and more particularly, to a character input / editing device capable of efficiently designating a character string to be edited when performing editing work such as correction and deletion of input characters. It relates to the device.

[0002]

2. Description of the Related Art In a character input / editing device that inputs and edits data for outputting characters from a character output device such as a computer typesetting machine, a character inputting / editing device that corrects or deletes input characters or a command for instructing typography. Perform editing work.

Characters to be corrected or deleted are generally designated by a cursor. To specify a continuous string, move the cursor to the first character of the string and specify that it is the first character, then move to the last character of the string and the last character. Has been specified.

[0004]

However, in the above method, 1
It is necessary to specify twice and to move the cursor to specify one character string. If the first character or the last character of the specified character string is specified incorrectly, all must be canceled and the correct command must be issued again.

Further, even when all character strings having a certain unity, such as heading, sorting, and vertical / horizontal / horizontal commands are specified, the first and last characters of the character string must be specified. It was very cumbersome and could lead to incorrect designations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1A is a diagram showing an example of the structure of data handled by the character input / editing apparatus of the present invention. In the following description, the data handled by the character input / editing device of the present invention is called internal data.

As shown in the figure, the internal data is composed of a command 11 and character information 12. As illustrated in FIG. 1B, the command 11 is a command type 11A indicating a command type (for example, a heading, sorting vertical-in-horizontal, etc.), command information 11B that is its actual information, and its command 1.
It is configured to include at least a coordinate (X, Y) 11C on the display unit 1 and level information 11D of the command for designating a character string described later.

Character information includes character code 12A, typeface information 12B, and character size 12 as shown in FIG. 1 (3).
C, transformation information (identical, italic, elongated, etc.) 12D, coordinates (X, Y) 12E on the display portion of the character, and level information 12F of the character for designating a character string described later are provided at least. Composed.

FIG. 2 is a diagram showing the construction of an embodiment of the character input editing apparatus of the present invention. In FIG. 2, reference numeral 21 is a CPU, 22 is a system bus, and 23 is an input unit, which includes a keyboard, a mouse, and the like. 24 is a display unit, 24 a is a display control unit, 25 is an internal data memory for storing internal data as illustrated in FIG. 1, 25 a is a memory control unit for controlling the internal data memory 25, and 26 is a display unit 24. An edit screen control unit for controlling the edit screen, 27 is a character pattern memory that stores a plurality of character pattern data, 28 is a character pattern memory 27 that reads the character pattern data as needed, A character generation unit for generating a character having a shape, and 29 is a set processing unit, which has an internal data memory 25 for displaying characters on the display unit 24 in a form close to an actual printed matter.
The internal data stored in the table is processed to obtain the coordinates of each character on the display unit 24. Although not displayed, the command coordinates are also calculated. An edit control unit 30 controls input of characters and commands, edit processing such as correction and deletion, and designation of a character string to be edited.

First, the level information 11D of the command 11 and the level information 12F of the character information 12 when the command is set will be described. FIG. 3A is a conceptual diagram of an example of internal data stored in the internal data memory 25.
In the figure, the upper part is character information, and the numerical value attached below is the level information 12F of each character. As shown in the figure, the level information 12F is all 0 when no command is set. In accordance with the internal data, the display unit 24 displays coordinates (X, X, X) on the display unit 24 in a form indicated by the typeface information 12B, the character size 12C, and the deformation information 12D of each character.
Y) It is displayed at the position of 12E. Of course level information 1
2F is not displayed.

When the operator inputs from the input unit 23 the heading commands 11Ms and 11Me before the first character and after the last character as shown in FIG. 3B, the edit control unit 30 causes the internal data memory 25 to operate. Command 11
Level information 1 for all characters sandwiched between Ms and 11Me
Rewrite the data on the second floor by adding one. Therefore, FIG.
In the example of (2), the level information 12F of the characters "U" to "Chi" is incremented by 1 and becomes 1.

In this way, the command 1 for further distribution
1Fs, 11Fe, vertical and horizontal commands 11Ts, 11T
When you input e, the characters between the commands and the level information of the command are 1 as shown in Fig. 3 (3) and (4).
Up. That is, when a new command is set, 1
Up level information. It should be noted that FIG. 3 conceptually sequentially illustrates changes in the internal data due to command input, not changes on the display unit 24. In the present invention, no command is displayed on the display unit 24.

As described above, each character and command of the internal data of the character input / editing apparatus of the present invention has level information corresponding to the input position of the command.

Next, the designation of the character string will be described. The editing control unit 30 controls the designation of the character string. FIG. 4 is a processing flow showing a processing procedure for specifying a character string. When the operator issues a command to move the cursor from the input unit 23, the cursor sequentially moves the positions of the character coordinates (X, Y) 12E and the command coordinates (X, Y) 11C on the display unit 24 to move the cursor to the desired character. To stop. FIG. 5 (1) shows that the cursor 51 is located at the character "ko". That is, the character "ko" is specified.

When the operator gives a section designation command from the input unit 23, the edit control unit 30 causes the internal data memory 25 to operate.
The level information 12F of the character at the cursor position is accessed to recognize the level of that character (S1 in FIG. 4). The level of the character is now A.

Next, the editing control unit 30 controls the coordinates (X, Y) 12E of the character of the internal data and the coordinate (X, Y) 11 of the command.
According to C, the character is sequentially searched in front of the character to find the command 11 that appears first (S2). In the example of FIG. 5 (1), the vertical, horizontal, and horizontal commands 11Ts correspond to this. Next, the level information 11D of the command 11 is accessed to recognize the level of the command (S3). Now, let the level of the command be B.

Next, the levels A and B are compared, and when A ≠ B, that is, when A = B, the command further ahead is searched (S4). On the other hand, when A ≠ B, the character immediately after the command is set as the start character S of the designated section (S5). Figure 5
In the example of (1), the level of the character "ko" is 3, and the level of the vertical-in-horizontal command 11Ts is 2, so 3 ≠ 2, and the character "ke" immediately after the vertical-in-horizontal command 11Ts is the start character of the specified section. It becomes S.

Next, a command of the same level as the command immediately before the start character of the designated section is searched backward (S6).
In the example of FIG. 5 (1), the vertical, horizontal, and horizontal commands 11Te correspond to this.

The character immediately before the command is set as the end character E of the designated section (S7). In the example of FIG. 5 (1), the character “sa” immediately before the vertical, horizontal, and horizontal commands 11Te is the end character E of the designated section.

The characters from the start character S to the end character E determined as described above are set as the designated section (S8).

The edit screen control unit 26 reversely displays the characters in the designated section selected as described above on the display unit 24 as shown in FIG. 5B, for example. In the figure, the shaded area is designated section 5
It is 1a.

Next, a case where the designated section designated as described above is further expanded will be described. When a section expansion command is given from the input unit 23, a command immediately before the specified section is searched. In the case of FIG. 5 (2), the distribution command 11Fs corresponds to this. Next, search backward for a command at the same level as the command behind it (Fig. 5 (2)).
Then, the command 11Fe) and the characters sandwiched by each of these commands are set as the enlarged designated section. The designated section 51b in which the shaded area in FIG. 5 (3) is expanded from the designated section in FIG. 5 (2)
Is.

On the other hand, when the section reduction command is given from the input unit 23, the processing opposite to the enlargement is performed to reduce the designated section. That is, when there is a designated section 51b as shown in FIG. 5 (3), a command that first appears backward from the start character of the designated section is searched, and a command at the same level as that command is searched from the end character of the designated section to the front. Search for. The character between the two commands is designated as a small designated section. If the section in FIG. 5 (3) is reduced once, it becomes the designated section 51a as shown in FIG. 5 (2) again.

FIG. 6 shows an example in which the section is designated with the cursor at a position different from that of FIG. When the section is expanded once with the cursor 61 at the position of FIG. 6 (1),
As shown in FIG. 6 (2), the designated section 61a is all the characters between the distribution commands 11Fs and 11Fe. Further, if the section is reduced in this state, the designated section 61 as shown in FIG.
b is all the characters between the commands 11Ts and 11Te in the vertical and horizontal directions. Therefore, if you want to specify the characters between the vertical, horizontal, and horizontal commands as the specified section, you can specify the desired character string by combining the section expansion and section reduction without moving the cursor to the character in that section. it can.

The embodiments of the present invention have been described above. Although the command is not displayed on the display unit in the above-mentioned embodiment, it goes without saying that the command may be displayed.

[0027]

As described above, according to the present invention, when a character string having a certain unity, for example, a character string for which a command such as heading, sorting, vertical-in-horizontal, etc. is designated, all of them are specified. The desired character string can be specified by simply moving the cursor to that character and specifying. In addition, since the specified section can be enlarged or reduced arbitrarily, the speed of specifying the character string to be edited is greatly improved and erroneous operations are significantly reduced, and editing work such as correction and deletion can be performed efficiently. Have an effect.
