DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus,
In particular, it relates to setting of a range for setting a print format for an arbitrary portion of a document and cancellation of the range.

[0002]

2. Description of the Related Art Conventionally, for example, in a word processor having a display or a printing mechanism of a dot printing system, a text memory is provided in a control device thereof, and data of a plurality of documents input from a keyboard or the like is stored in the text memory. It can be memorized. By the way, during the input of document data, the memory for these print format data can be set for any part of the document, such as character modification such as underlining and bold, and font format and character size. Are separately provided in the control device.

That is, for example, the document data "ABCDE"
To underline the character string "ABC" in "F", first move the cursor to the character "A" to set the underline mode, and then operate the cursor movement key or the underline key to move the cursor. Is moved to the character "C" to release the underline mode. As a result, the character data "A", "B", and "C" are each provided with character modification data indicating an underline, and these character examples "ABC" It is displayed on the display with an underline based on the data and printed.

[0004] By the way, as the character modification data,
Each of various character modifications including 1 byte or 2 bytes, including underline and bold, is assigned to a predetermined bit, and when character modification is set,
Flag data of “1” is set in the corresponding bit. On the other hand, when releasing the underline, the underline release mode is set in the same manner as described above, and the cursor movement key or the underline key is operated. As a result, flag data of "0" is set in the corresponding bit of the character modification data associated with each underlined character code, and these characters are displayed and printed without underlining.

[0005]

As described above, in a conventional word processor or the like, it is possible to freely set a print format such as character modification to an arbitrary portion of an input document. When canceling the print format set for a part, you must operate the cursor movement keys etc. to release each character for which the print format has been set, almost in the same way as when setting the print format. There are problems that the operation for canceling the format becomes complicated and that a large-capacity memory is required to store the print format data for setting the print format.

[0014] Next, the control system of the tape printer 1, FIG. 3
Is configured as shown in the block diagram of FIG. Driving a keyboard 3, a display controller (LCDC) 23 having a display RAM for outputting display data to a liquid crystal display (LCD) 22, a drive circuit 25 for driving the thermal head 13, and a tape feed motor 24 And a drive circuit 21 for the warning buzzer 20 are provided with an input / output interface 27 of the control device C.
Connected to each other. The control device C includes a CPU 29,
An input / output interface 27 and a CGROM 3 connected to the CPU 29 via a bus 28 such as a data bus.
0, ROMs 31 and 32, and a RAM 40.

CGROM (pattern data memory) 30
Stores dot pattern data for display corresponding to the code data for each of a large number of characters. In a ROM (outline data memory) 31, outline data (outline data) for defining the outline of the character for each of a large number of characters in order to print the character is a typeface (Gothic typeface, Mincho typeface, etc.). Each code is classified and stored in association with the code data.

The ROM 32 includes a display drive control program for controlling the display controller 23 in accordance with character code data such as characters, numbers and symbols input from the keyboard 3, and outlines corresponding to each code data in the text memory 41. image development processing control program to expand the data in the print buffer 45 by conversion to dot data, a print buffer 4 3 of the thermal head 13 data Te sequentially reads and tape feed motor 2
4, a print drive control program for driving the printer 4, a control program for tape print control described later, which is unique to the present application, and the like. It should be noted that the image development processing control program includes various subroutines for controlling character modification processing such as bold, underline, and white outline for a character.

The line buffer 41 of the RAM 40 temporarily stores document data including code data of a plurality of characters and symbols input from the keyboard 3. The text data from the line buffer 41 is stored in the text memory 42. The print buffer 43 stores print data of characters and symbols developed into images.

Next, the routine of the tape print control performed by the controller C of the tape printer 1, FIG. 4 to FIG.
6 will be described. In this control, various character modifications can be made to any part of the document such as underline, bold, and white, but the setting control for setting these is the same in any case. Is set. In the figure, reference symbol Si (i = 10, 11, 1
2) are the respective steps. When the power is turned on by operating the power key, this control is started, and initial settings such as clearing the memories 41 to 43 are first performed (S
10) When the document creation key is operated to create document data (S11 / S12: Yes), the document data consisting of a plurality of code data input by the subsequent operation of the character key or the like is stored in the line buffer 41. While storing the code data, the code data is displayed on the display 22, and a document creation process for storing the document data in the line buffer 41 in the text memory 42 is performed by operating the end key (S13), and the process returns to S11. For example, when the character string "ABCDEFHIJ" is inputted as shown in FIG. 7 is stored encoded data in these strings sequentially and the line buffer 41 and text memory 42, the display of these strings, as shown in FIG. 8 22 is displayed.

Next, when the cursor right movement key or the cursor left movement key is operated (S11: Yes, S1
2: No, S14: Yes), when the cursor K can be moved based on the cursor display position and the type of the cursor movement key (S15: Yes), the cursor display position is shifted one digit to the right based on the type of the cursor movement key. It is moved one digit to the left (S16) and the process returns to S11. However, when the cursor left movement key is operated when the cursor display position is at the beginning of the character string, or when the cursor right movement key is operated when the cursor display position is at the end of the character string (S
15: No), the buzzer 20 sounds for warning (S)
17). Next, when the underline key is operated to apply underline modification to the character string (S11: Y
es, S12 / S14: No, S18: Yes), underline setting processing control (see FIG. 5 ) is executed (S
19).

When this control is started, it is determined whether or not an underline can be set, that is, whether or not there is a character code at the cursor display position. If there is a character code (S30: Yes), the cursor is first set. The character at the display position is highlighted. For example, as shown in FIG. 9 , when the cursor K is moved over the character "D" by operating the cursor movement key and the underline key is operated, the character "D" is highlighted. Next, when the cursor movement key is operated (S32 / S33: Yes), when the cursor K can be moved (S34: Yes), the cursor display position is shifted by one digit to the right based on the type of the cursor movement key. If the character is moved to the left by one digit and the character at the destination is normally displayed (S35: Yes), the character is highlighted (S35).
36), and return to S32. That is, the range in which the underline modification is performed is designated by the reverse display of these character strings. For example, when the cursor right move key has been operated twice, as shown in FIG. 1 0, letter "DEF" is highlighted.
The cursor movement key is operated (S32 / 33: Ye
s) and when the cursor K can be moved (S34: Y
es), if the destination character is highlighted (S
35: No), the reverse display of the character is stopped, the character is displayed normally (S37), and the process returns to S32. When the cursor movement key is operated (S32 / S33: Ye
s), when the movement of the cursor K is impossible (S34:
No), the buzzer 12 is sounded (S38), and the process returns to S32.

Next, when the setting key is operated (S
32: Yes, S33: No, S39: Yes), in the document data of the line buffer 41, setting data SD for setting an underline at the start position of the underline setting range is stored (S41), and furthermore, this setting is performed. The start code SC is inserted and stored at the beginning of the underline setting range including the data SD, and the end code EC is inserted and stored at the end of this setting range, and the document data of the line buffer 41 is stored in the text memory 42 ( S42).

Here, the setting data SD will be described. The setting data SD is composed of, for example, one byte, and corresponds to each of bits "0" to "7".
A setting flag for underlining, a setting flag for bold, a setting flag for italic font, etc. are assigned to specific bits, respectively, and when set, flag data of "1" is stored. It is supposed to be. For example, as shown in FIG. 1 1, the character string "DEF"
Is set as the underline setting range, the setting data SD including the underline setting is stored at the head position of the setting range, and the start code SC is set at the head of the setting range.
Is inserted and stored, and an end code EC is inserted and stored at the end of the set range.

Next, the reverse display of the character strings indicating these setting ranges is stopped (S43), and the document data of the line buffer 41 is displayed on the display 22 (S44).
This control ends and the routine returns. For example, as shown in FIG. 1 2, together with the character string "ABCDEFHIJ" is displayed, along with setting the start mark SM is displayed at the top of the underline setting range, to display the setting end mark EM to the end of the range You. When the cancel key is operated (S32: Yes, S33 / S39: N
o, S40: Yes), after the above S43 and S44 are executed, this control is terminated and the routine is returned. When a key other than the cursor movement key, the setting key, and the cancel key is operated (S32: Yes, S33, S39,
(S40: No), the buzzer 12 is sounded (S38), and S
Return to 32.

Next, when the backspace key is operated to erase characters (S11: Yes, S12.S1
4. S18: No, S20: Yes), erasure processing control (see FIG. 6 ) is executed (S21). When this control is started, the cursor K is not at the display position corresponding to the first character in the line buffer 41 (S50: No), and the code data on the left side of the cursor K is the start code SC
However, if it is not the end code EC, that is, if it is a character code (S51 / S52: No), the code data on the left side of the cursor K is deleted from the line buffer 41, and each code data following the deleted code data is deleted. There is moved to the beginning address direction, it is further stored document data of the line buffer 41 in the text memory 4 2 (S56), the latest document data in the line buffer 41 is displayed on the display 22 (S55), this control ends And return.

On the other hand, when the code data on the left side of the cursor K is the start code SC (S51: Yes) or the end code SC (S51: No, S52: Ye)
s), start code SC, end code EC, and setting data S
And D is deleted from the line buffer 41 (S53), with each code data subsequent to the erased these encoded data is is moved to the beginning address direction, the document data in the line buffer 41 is stored in the text memory 4 2 (S54), the latest document data in the line buffer 41 is displayed on the display 22 (S55). For example, as shown in FIG. 1 2, underline setting mark S
M, when the EM and documents "ABCDEFHIJ" is displayed, after moving the cursor K to the letter "D" or "H", when the backspace key is operated, start mark SM as shown in FIG. 8 And the end mark EM are erased, and only the document is displayed.

Next, a document creation key, a cursor movement key,
When a key other than the underline key and the backspace key is operated (S11: Yes, S12 · S1
4, S18, S20: No), processing control corresponding to the operated key is executed (S22). For example, when the print key is operated, a printing process is executed based on the document data in the text memory 42. Here, since this printing process is not directly related to the present invention, it will be briefly described that outline data corresponding to the code data sequentially read from the text memory 42 is read out, and the enlargement ratio of the printing character is obtained. The outline data is subjected to enlargement processing and character modification processing using the enlargement ratio, and further, print data as dot data is created from the outline data after the processing, and is printed by the printing mechanism PM.

As described above, using the start code SC and the end code EC, the range in which the character modification is set for an arbitrary part of the document is specified, and any of the start code SC and the end code EC is used. When one of them is erased, the other code data SC / EC is also erased at the same time, so that the setting range canceling operation is greatly simplified. Therefore, it is not necessary to set the setting data SD indicating underlining with respect to each character in the document portion, and the storage capacity for the setting data SD can be greatly reduced.

In the tape printing control, the setting control for setting the underline has been described. In addition, it is possible to control so-called printing format such as bold, shadow character, character size, and the like. is there. It is needless to say that the present invention can be applied to a document processing device such as a European word processor or a Japanese word processor which has a display mechanism and a printing mechanism and a text memory and can print in various printing formats.
