Abstract

PURPOSE:To prevent the erroneous setting of an amount of indent by providing an indent amount memory means which stores selectively plural indent amount set during production of documents and a means which indicates the action and its release of the indent. CONSTITUTION:The characters of a desired sentence are supplied with the operation of a character input key of a keyboard device 1 and then stored in a sentence buffer 41 of an RAM4. A space character of a prescribed amount is fed to obtain an indent amount of a sentence B to be indented following a sentence A. Then an indent key 13 is operated, and therefore the indent amount is stored in an indent buffer 42 of the RAM4. The position indicated by the key 13 is set at the head of a line with input of the sentence B, and a sentence starts at this head position. When an indent release key 14 is operated at a position b2, a sentence C having no indent is printed. Then the key 13 is operated after a function key 15 to read the indent amount out of the buffer 42. Then a sentence D is printed with indent of the same amount.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an indentation control method for indenting and indenting the beginning position of a line of a text during text creation in a document processing device.

Prior Art Conventionally, when processing a document in which a part of a sentence is indented while creating a series of sentences, then the indentation is canceled and the indentation is performed again, the amount of indentation is set for each indentation. ing. Then, you may accidentally set an indentation amount that is different from the indentation amount that was previously set, and the text will be created in an unsightly arrangement.Purpose The purpose of the present invention is to prevent operational errors and create beautiful sentences. An object of the present invention is to provide an indentation control method for a text processing device that completes the state.

EXAMPLE FIG. 1 shows a text created in accordance with the present invention. Text A is printed or displayed within one page without indentation, the indent amount is set at position b1, and text B is printed or displayed without indentation.
is displayed or printed while being indented, and then the indentation is canceled at position b2. As a result, text C is printed or displayed without being indented. Thereafter, when the text is indented again and printed or displayed, it is indented by the same amount of indentation as text B. After finishing writing the text, the indentation is canceled at position d1, and the text E is displayed or printed without being indented. After setting the indentation amount l of the text to be indented for the first time in this way, the text can be indented by the same indentation amount d thereafter. Therefore, sentences B and D are indented, resulting in a beautiful finish.

FIG. 2 is a block diagram of one embodiment of the present invention.

The keyboard switch 1 includes a character input key 11 and a plurality of control keys 12 operated to instruct editing. The control keys 12 include an indent key 13 for indenting and instructing, an indent cancel key 14 for canceling indent control, and a function key 15 for instructing other controls prior to operating the indent key 13. Function keys 15 can also be modified to perform other control operations in conjunction with other control keys. This keyboard device 1
From there, a character code corresponding to or related to the operated character input key 11 and a code related to the control key 12 are generated and supplied to the processing circuit 2. The processing circuit 2 performs editing control according to an editing control program stored in the read-only memory 3. This editing control program includes a program for controlling indentation according to the present invention. The random access memory 4 includes a text buffer 41 that stores edited text data input from the character input key 11, and an indent buffer 42 that stores the amount of indentation indented by the indent key 13 for each setting instruction.
, a character count counter 43 that counts the number of characters input in a line, and pointers 44 and 45 that are used when reading or writing data from the 1-indent buffer 42,
It includes a 7lag 47 that is set when the function key 15 is operated, and an area for storing various other buffer flags used in editing control.

Recording control of the printer 6 is performed by the control circuit 5, and the text data in the text buffer 41 is printed and recorded to create a text. The display device 8 such as a cathode ray display device is
It is controlled by the display control circuit 7. This display control circuit 7 includes a memory 71 that stores data to be displayed. The display memory 71 stores data in the text buffer 41 and characters input using the character input key 11.

Next, the operation according to the operation of the keyboard device l will be briefly explained. Characters are entered into the text to be created by operating the character entry key 11. When indenting text B as shown in FIG. 1, a desired amount of indentation is obtained. Enter a character or a space character, and then operate the indent key 13. Generally, a space character is input as a margin on the left side of horizontal writing. Thereafter, when sentence B is input, the position specified by this indent key 13 is set as the beginning of the line, and the sentence begins from this position.

When inputting text C exclusively at the original position, that is, the left margin, the indent release key 14 is operated at position b2, thereby printing or displaying text 0 without indentation. Thereafter, in order to print or display the text indented by the same amount of indentation as the previous text, the function key 15 is operated, and then the indent key 13 is operated. Therefore, data indicating the previous indentation amount is automatically read out, and the text is displayed or printed while being indented by the same indentation amount.

Referring to FIG. 3, in order to input a sentence, the character input key 11 is operated in step 10''0, and then the character input is performed.The input character code is stored in the sentence buffer in step 101. At step 102, the input characters are stored in the display memory 71, and thereby the input characters are displayed on the display device 8.In step 103, the contents of the number-of-strokes counter 43 are incremented by l and counted. This operation is repeated each time each character is input, resulting in the storage state of the text buffer 41 shown in FIG. 4(1).

When one line of text is input and the number of strokes counter 43 reaches a preset number of strokes, or when the line feed key included in the control keys 12 is operated, step 110 is executed. Line feed data is sent to the text buffer 41 in step 111.
In addition, in step 112, the line feed data is stored in the display memory 71, so that the line feed data is stored in the display device 8.
displays a symbol indicating that a line break should occur. Step 1
13, the number of strokes counter 43 is reset.

In step 114, the data at the position corresponding to the content P1 of the pointer 44 in the indent buffer 42 is read out, and it is determined whether the data is blank (Null). At the initial stage of operation, the content P1 of the pointer 44 is blank, and "0" indicating a blank is also stored in the storage area of the address O in the storage state shown in FIG. 5 of the indent buffer 42. There is. This generally allows the start of writing to be entered from the horizontal left margin 1. At step 114 in FIG. 3, the contents of the pointer 44 are blank, so the operation ends. In this way, sentences are stored in the sentence buffer 41 as indicated by the reference numeral 41a in order to display or print the sentence A in FIG.

At the end of this store area 41a, a line feed key included in the control keys 12 is operated.

The operation when indenting and manipulating the text B shown in FIG. 1 will be explained. The operator operates the space character key included in the control keys 12, and inputs the space indicated by the reference mark SP into the store area 41b by the amount of indentation, as shown in FIG. Thereafter, the indent key 13 is operated. This causes the operation of step 135 to be performed.

In step 131, it is determined whether the content F of the flag 47 is "1". If not, the process moves to step 132, where the content of the number of characters printed counter 43 is incremented by one. In step 133, the storage area 41o of the text buffer 41 is
Indentation keys are stored in . Step 134
Then, the indentation symbol code is stored in the display memory 71, and the display device 8 displays that it is an indentation. In step 135, the content P of the pointer 44 is
1 is increased by 1. In step 136, the data of the number of strokes counter 43 is stored in a corresponding position of the indent buffer 42, for example, 1 (see FIG. 5). In this embodiment, "2" is stored in the store area of address E1. The text is then input starting from the indented first position. When a line feed instruction is given, the operation of step 115 described above is executed. At step 114, the content P1 stored in the pointer 44 of the indentation buffer 42 stores position number 1 and is not blank, so the process moves to step 115. This allows display memory 7
The input position of 1 is skipped by the data stored in the indent buffer 42, or a blank space 5 is stored.

To set the next sentence C to the left position without indenting it as shown in FIG. 1, the indent release key 14 is operated at the indent release position b2. As a result, the operations from step 160 onwards are executed. In step 161, the code corresponding to the indent release key 14 is stored in the text buffer 41, and in step 162
Then, the content P1 of the pointer 44 is incremented by 1. In step 163, a blank space is stored in the indent buffer 13 at the position corresponding to Pl. In step 164, the indentation cancellation symbol code and line feed code are stored in the display memory 71. In step 165, the number of strokes counter 43 is reset. In this way, when inputting a text thereafter, the text O is created with the left margin as the beginning of the line without being skipped in step 115. A margin is formed in which each line of text 0 is skipped above.

The operation of creating a text by indenting it by the indentation amount in the same way as the above-mentioned text B will be explained. It is assumed that the amount of indentation in the text is 3, that "3" is stored in the position number 3 of the indent buffer 42, and that the content P1 of the pointer 44 indicates position number 5. Prior to operating the indent key 14, the function key 15 is first operated. This causes the content F of the 7lag 47 to be set to logic rlJ in step 131. After that, when the indent key 13 is operated, the process moves from step 131 to step 140.
The content P'1 of the pointer 44 is transferred to the pointer 45,
The content of the pointer 45 becomes P2.

It is determined in step 141 whether the position 4 indicated by Pl in the indent buffer 42 is blank. If it is blank, the content P1 of the pointer 44 is decreased by 1 in step 142. When a blank is detected in step 141, the process moves to step 143, where the content P2 of the pointer 45 is incremented by 1, and the positional work 5 is stored. The position 3 indicated by Pl in the indent buffer 12 is transferred to the position 5 indicated by the content P2 of the pointer 45. Therefore, each time data "3" is stored in the positioner 5 in step 143. The position number 5 representing the content P2 of the pointer 45 is transferred to the pointer 44 in step 145, and then, in step 146, the number of strokes counter 43 is set to the value corresponding to the data "3" at the position indicated by Pl in the indent buffer 42. do. Step 1
At step 47, a space character corresponding to the stroke number buffer 43 and an indentation code are stored in the text buffer 41, and at the same time, at step 148, a space character and a symbol code are stored in the display memory 71 in the same manner. Thereafter, in step 149, the contents of the flag 47 are reset, and the indentation operation is completed. In this way, in the text buffer 41, after text B is stored in the store area 41 and text C is stored in the store area 41F, three blanks are stored in the store area 41G.

"3" is stored in the position number 5 of the indent buffer 42, as in the position number 3. In this way, the amount of indentation between text B and text becomes the same <3, and the present invention prevents the indentation amount from being set incorrectly as in the prior art described above.

In the embodiment described above, when displaying on the display device 8, the indent amount is skipped in step 115 so that it becomes a margin, but when it is stored on the printer 6, it is not printed as a space character. Good too.

Alternatively, it may be temporarily set as the left margin, which is the first position of the position indented by the indent amount. At this time, when the indent code is read from the text buffer 41, the contents of the indent buffer 42 are referred to, and the left margin is the first position of the indented position. A margin will be created for the data.

When the indent key 13 is operated after operating the function key 15, in the embodiment described above, the previous indent setting value stored in the indent buffer 42 is retrieved.
Although the automatic setting is performed, in another embodiment, the indentation buffer 42 is sequentially read backwards until a predetermined indentation setting value appears on the display screen of the display device 8. When the indent setting value becomes a desired value, the indent setting value may be selected to set the indent amount.

Effects As described above, according to the present invention, indentation can be performed by the same amount as the previously set indentation amount, so beautiful sentences can be created without accidentally setting the indentation amount. .
