Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a text editing processing device such as a so-called word processor that automatically edits and prints Japanese and English texts.

This text editing processing device inputs character data for a document to be created from a character input device, automatically edits the input character data into a specified document format, and then uses a printing device to create a document in a predetermined format. It is something to do.

When editing the above-mentioned input character data into a specified document format, the status of the input character data is displayed on a CRT display device, and the operator gives instructions regarding various formats while looking at this display device.

The present invention corrects character data once input in such a text editing processing device,
When moving a predetermined input data block at a certain line position to the left margin position, erase the character data to the left of the first character of the predetermined character data block one by one by operating the delete key, and according to this deletion operation. This method moves a predetermined character data block to the left one character at a time, but when the distance to be moved exceeds 3 or 4 characters, the deletion key must be operated in a complicated manner, and this movement operation is troublesome and The operation time was long and the operability was very poor.

The present invention solves the above-mentioned problem, and allows a left-shifting operation to be performed with a so-called one-touch operation.

The left-justifying function of the apparatus of the present invention will be specifically explained below.

FIG. 1 is a block diagram showing the configuration of the device.
Reference numeral 1 denotes an input device which includes various character keys and function keys. Among the function keys, there are particularly provided a left shift instruction key 1A and a cursor movement instruction key 1B.

A key control circuit 2 converts a key signal sent from the input device 1 into a code signal.

3 is an editing control circuit which transfers character data input from the input device 1 to the text memory 4 and also executes various editing controls in response to operation of a function key. Especially the left-filling instruction key 1
In response to the operation of A, control is performed to execute the operation shown in FIG. The circuit 3 is provided with a flag F indicating this left-shifting control state.

Character data is read/written in the text memory 4 based on address control by the address circuit 5.

Reference numeral 6 denotes a CRT display device to which text data from the text memory 4 is supplied and displays it on the screen.

Reference numeral 7 denotes a printing device consisting of a dot printer, which prints the text data in the text memory 4 according to document format information to create a predetermined document.

A cursor counter (KC) 8 counts up or down in response to a movement instruction from the cursor movement instruction key 1B of the input device 1. The counter (KC) includes an X counter section indicating the row direction and a Y counter section indicating the column direction, and the counter value is stored in the text memory 4.
They correspond to the cursor mark positions on the CRT display device 6, respectively.

Reference numerals 9 and 10 denote address pointers P ₁ and P ₂ , which have the same structure as the cursor counter (KC) 8, that is, each has an X counter section and a Y counter section.

Reference numeral 11 denotes a buffer register capable of storing character data (code) for at least one character, in which character data sent from the text memory 4 or space data (code) sent from the space code generation circuit 12 is stored. be introduced. This space code generation circuit 12 is driven based on instructions from the editing control circuit 3.

Reference numeral 13 denotes a determination circuit that determines whether or not the character data (code) transferred from the text memory 4 to the buffer register 11 is included in the space data (code).
is inputting to.

The specific configuration shown in FIG. 1 is operated according to the flow shown in FIG.

Next, the operation of the configuration shown in FIG. 1 will be explained according to the flow shown in FIG.

First, when a character key of the input device 1 is operated according to the manuscript, character data (character code) corresponding to this character key is stored in the text memory 4 whose address is specified by the address circuit 5 via the editing control circuit 3.
, and the text memory 4 stores the predetermined text data.

The text data stored in this text memory 4 is
It is displayed on the CRT display device 6.

Therefore, the operator looks at this display device 6 and gives instructions regarding various formats.

Now, regarding the input character data, if the operator wants to move a block of predetermined character data at a certain line position to the left margin position, the operator indicates the line position of the character data block to be moved.

In other words, the cursor movement instruction key 1B of the input device 1
While looking at the CRT display screen, set the cursor mark at the line position where the character data block is located.

Due to this cursor mark set, the X counter section and Y counter section of the cursor counter (KC) 8 each have a value corresponding to the cursor mark position.

Thereafter, by operating the left shift instruction key 1A of the input device 1, the operation according to the flow shown in FIG. 2 is specifically executed.

As shown in step 101, first, the value of the X counter holding the row address value of the cursor counter (KC) 8 is set to the pointer (P ₁ ).
The address value corresponding to the first position of the column is set in the Y counter section of pointer (P ₁ ) 9. Then step
Proceeding to 102, the value of the X, Y counter section set in the pointer (P ₁ ) 9 is transferred to the pointer (P ₂ ) 1.
Transfer to the X, Y counter section of 0.

The values of the X and Y counters set in the pointer (P ₂ ) 10 are transferred to the address circuit 5, and character data (character code) in the text memory 4 is read out based on this address value as shown in step 103. be done.

This takes out the character data at the beginning position (left end of the line) of the line in which the character data block to be left-justified is located, and causes the determination circuit 13 to check whether it is in the space code or not. Step 104). In other words, it checks what kind of character data currently exists at the position to be shifted to the left. Originally, the position to be left-justified must contain space data (code), but if the required character data is present due to an operational error in the left-justification specified position, left-justification cannot be performed.

Therefore, if a code other than a space code is detected in step 104, it is determined that an operation error has occurred, and the process proceeds from 108 to 115 to 116, and the left-justification function is not executed.

On the other hand, if a space code is detected in step 104, the process proceeds to steps 105→106→107.

In this case, a flag F is set to set the left-justification mode, and then the Y counter section of the pointer (P ₂ ) 10 is counted up by "1". Then, a check is made to see if the value of this Y counter is at a position exceeding the unused line.

These steps 103→104→105→106→107 are repeated until character data other than the space code is read out (check at step 104) or until the blank line is exceeded (check at step 107).

Therefore, when character data is detected in the step 104, the process proceeds to the step 108 side, so the Y counter section of the pointer (P ₂ ) 10 stops counting up, and the pointer (P ₂ ) 10 has a point exactly on the left. This is the address value of the first character position of the character data block to be added.

Also, in step 107, the pointer (P ₂ ) 1
If it is detected that the address field of 0 exceeds the blank line, it means that there is no character data in the specified line, and the process then proceeds to steps 115 → 116, and the left-justification function does not actually work. .

When character data is detected in step 104 and the process proceeds to step 108, since flag F is set, the process proceeds from steps 109 to 110 to 111.

That is, the character data in the text memory 4 located at the address value of the pointer (P ₂ ) 10 is transferred to the pointer (P ₁ ).
The rewrite control is performed to the position indicated by the address value 9, and then the Y address portions of the pointers (P ₁ ) 9 and (P ₂ ) 10 are incremented by "1".

Thereafter, it is checked whether the Y address portion of the pointer (P ₂ ) 10 has exceeded the unused row, and steps 109 to 111 are repeated until the state in which the unused row has been exceeded is detected in step 111.

This repetitive operation sequentially shifts the character data following the first character data to the left.

Thereafter, when it is detected in step 111 that the Y address portion of the pointer (P ₂ ) 10 has exceeded the end of the line, the process proceeds from steps 112 to 113 to 114. That is, the space code generation circuit 12 is driven to write a space code to the location of the text memory 4 at the address value indicated by the pointer (P ₁ ) 9. Then, the Y address part of the pointer (P ₁ ) 9 is counted up by "1", and then the pointers (P ₁ ) 9 and (P ₂ ) 10
Check whether the values of
Repeat 114.

This is to insert space codes in sequence in the margin after the left-aligned character data block.

When the values of the pointers (P ₁ ) 9 and (P ₂ ) 10 become equal, that is, the insertion operation is performed to the end of the line, the process proceeds to steps 115→116.

This increments the X address field of pointer ( _P2 ) 10 by "1", sets this value in the X address field of cursor counter (KC) 8, and sets this Y address field as the column start address value. . In other words, it is not necessary to move the cursor when subsequently aligning the next line to the left, and the left alignment key 1A
This is so that the next line can be shifted to the left simply by operating .

Then, the flag F is reset and this left shifting operation is completed.

As described above, if the user subsequently operates the left-filling key 1A to perform left-filling, the process returns to step 101 of the flow.

In addition, in the above embodiment, an example was shown in which space codes are automatically inserted sequentially after a predetermined data block is left-aligned until the end of the line. In the case of continuous data, the space code may not be inserted and the subsequent character data may be filled in sequentially.

As described above, in the text editing processing device of the present invention, when moving a predetermined data block at a line position of input character data to the left margin position, this can be done by a so-called one-touch operation of the left-justification instruction key. Therefore, it is possible to provide this type of text editing processing device which is excellent in operability in that data blocks can be left-justified easily and at high speed in data correction operations.
