As shown in FIG. 3, the tab information register section 17 stores the tab information. In this example, "Tab information register number"
As "0000", the 5th character, 10th character, 15th character
Specifies that tabs are to be set at the 1st, 20th, and 25th characters. Similarly, as "Tab information register number""0001", the second character,
Specifies that tabs are to be set on the 15th and 30th characters.

Next, the operation of the character processing device according to this embodiment will be explained.

In this embodiment, the keyboard 6 is operated to operate the device.

The tab set key 6B-2 and the tab reset key 6B-4 are used to set and reset a tab at the position of the cursor displayed on the cathode ray display tube 12. By operating the cursor key group 6E, the cursor is placed at a desired position.
By pressing the tab set key 6B-2 or the tab reset key 6B-4, the tab at the cursor position can be set or reset.

When the tab position is changed, the tab control section 16 assigns a new "tab information register number" to the tab information register section 17 and stores new tab information. That is, a new "tab information register number" is stored in the register of the tab number register unit 14 corresponding to the line where the cursor is placed. At this time,
If the same tab information as the changed tab information already exists in the tab information register section 17, the information is changed to the corresponding register in the tab number register section 14 without generating a new tab information register. Stores the already existing "tab information register number".

Next, when the tab selection key 6B-1 is pressed, the central processing unit 1 causes the tab control unit 16 to select the tab number register unit 1 corresponding to the line where the cursor is placed.
Change the contents of 4. That is, each time the tab selection key 6B-1 is pressed, the tab number register section 14
The corresponding registers are rewritten one after another, and appropriate tab information in the tab information register section 17 can be selected.

When the tab modification key 6B-5 is pressed, a transition is made to a tab modification mode in which the tab information in the tab information register section 17 is changed. That is, first, the tab information register having the youngest address in the tab information register section 17 is selected, and its contents are displayed on the surface of the cathode ray display tube 12. The monitor line shown at the bottom of FIG. 4 illustrates this. That is, the "tab information register number""0004" and its tab positions "5, 10, 15, 20, 25" are displayed. here,
The monitor line cursor is displayed as a cross mark. By operating the monitor cursor key 6F, you can move this monitor cursor left and right and select the character key group 6.
Use A to change the appropriate value. Next, when the line feed key is pressed, the central processing unit 1 transfers the changed tab information to the tab control unit 16 via the display control unit 10. The tab control unit 16 stores the tab information in the tab information register having the corresponding tab number. At this time, if a register with the same tab information already exists in the tab information register section 17, that register is deleted. At the same time, in the tab number register section 14, the tab number of the erased register is replaced with the tab number of the previously stored tab information register. Thereafter, the tab control section 16 transfers the contents of the next tab information register to the display control section 10 based on the command from the central processing section 1, and the display control section 10 transfers the transferred tab information to the monitor line of the display tube 12. Display above.

Furthermore, when tab modifier key 6B-5 is pressed,
Based on a command from the central control unit CPU1, the tab decoration mode is canceled. Therefore, the display control unit 10 erases the monitor line and returns to normal display.

When the tab save key 6C-1 is pressed, the tab control section 16 saves the contents stored in the tab information register section 17 to the floppy control section 2 based on a command from the central processing section 1.
Transfer to. Then, the floppy control section 2 records the contents on the floppy disk 4 via the floppy drive section 3.

On the other hand, when the tab read key 6C-2 is pressed, the floppy control unit 2
reads the tab information from the floppy disk 4 via the floppy drive unit 3, and then reads the tab information from the floppy disk 4 via the floppy drive unit 3 and
Transfer to 6. The tab control unit 16 stores the tab information in the temporary tab register unit 18.

Next, the tab control section 16 sequentially reads out the tab information from the temporary tab register section 18 and compares whether or not the same tab information exists in the tab information register section 17 . If the same tab information does not exist, a new tab number is assigned to the tab information register section 17 and stored. On the other hand, if the same tab information exists, the next process is performed without new storage.

After reading the last tab information from the temporary tab register section 18, the tab control section 16 erases the contents of the temporary tab register section 18, and finishes reading out the tab information.

When the document storage key 6C-3 is pressed, the tab control unit 16 writes necessary tab information stored in the tab information register 17 to the document tab register 15 based on a command from the central processing unit 1. here,
Necessary tab information means the tab information required for the document to be saved, and is stored in tab number register 1.
4. Subsequently, based on the instructions from the central processing unit 1, the document buffer unit 13,
The contents of the tab number register section 14 and the document tab register section 15 are written to the floppy disk 4 via the floppy control section 2 and the floppy drive section 3.

When the document transmission key 6C-5 is pressed, the document buffer section 1
3. Transfer the contents of the tab number register section 14 and the document tab register section 15 to the communication control section 7.
Then, the communication control section 7 sends the above-mentioned contents onto the line via the modulation/demodulation device 8 and the line control section 9.

When the document read key 6C-4 is pressed, the floppy control section 2 reads the floppy disk 4 via the floppy drive section 3 based on the command from the central processing section 1.
Reads the saved document, tab number, and document tab information from. Next, the central processing unit 1 stores these contents in the document buffer unit 13, tab number register unit 14, and document tab register 1, respectively.
5 and store. Next, the tab control section 16
Based on instructions from the central processing unit CPU1, the tab information is sequentially read from the document tab register section 15 and compared with the contents stored in the tab information register section 17. At this time, if there is no matching tab number and corresponding tab information in the tab information register section 17, its contents are written into the tab information register section 17. Further, if only the tab numbers match and the tab information does not match, the tab control section 16 adds a new tab number to the tab information register section 17 and records the above-mentioned unmatched tab information there. do. At the same time, the corresponding tab number in the tab number register section 14 is replaced with a new tab number.

In the above case, if only the tab information matches and the tab numbers do not match, the corresponding tab number in the tab number register section 14 is replaced with a new tab number (having the same tab information).
Replace with Further, in the above case, if both the tab number and the tab information match, no special processing is performed.

In this way, the tab number and tab information are read from the document tab register section 15 and the above-described processing is performed, and the tab control section 16 erases the contents of the document tab register section 15 when the last processing is completed.

When the document reception key 6C-6 is pressed, the communication control section 7 receives the document, tab number, and tab information via the line control section 9 and the modem 8 based on a command from the central processing section 1. The subsequent processing is the same as the processing performed by the central processing section 1 and the tab control section 16 when the document reading key is pressed.

Effects As explained above, according to the present invention, tab information previously created or used can be used, and tab information can be shared between character processing devices of the same type using external storage means. Therefore, it is possible to obtain a character processing device that greatly contributes to increasing the efficiency of document creation and editing.
