Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a character processing device that inputs a document using characters, symbols, etc. and edits the input document, and particularly relates to a character processing device that inputs a document using characters, symbols, etc., and edits the input document. The present invention relates to a character processing device equipped with a character processing device.

[Conventional technology]

Conventionally, in this type of character processing device, the decimal tab is usually used to input numbers.
If there is a border at the tab position where the cursor has been moved by decimal tab, there is an inconvenience that even if the cursor is moved by decimal tab and a number is entered by keystrokes at that tab position, the key input will not be accepted. Ta.

[Problem that the invention seeks to solve]

Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks, and also to automatically move the cursor to the next tab if there is a border at the tab position when the cursor is moved using a decimal tab. To provide a character processing bag M suitably configured to receive key input.

(Means for solving the problem) In order to achieve such an object, the present invention provides an input means for inputting a document using characters, symbols, etc., and a display for displaying the document inputted by the input means and a cursor. means and
A tab means for instructing tab processing, a means for determining whether or not there is a ruled line at the tab position designated by the tab means, and a means for moving the cursor to a predetermined position other than the ruled line when there is a ruled line at the tab position. and means for displaying on the display means.

[Function] According to the present invention, when using the decimal tab, even if there is a ruled line at the destination of the cursor movement, the cursor is automatically moved to remove the ruled line position. , can perform quick processing.

〔Example〕

The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention.

In FIG. 1, a is a key input means, and a decimal
It has a tab key DTX. +3-] is a means for determining whether there is a ruled line at the tab position when pressing the decimal tab key, and b-2 is a means for moving the cursor to a predetermined position when it is determined by means b-1 that there is a ruled line. This is a cursor control means that controls cursor movement so as to

C is key input means a1. :J: This is a control means for controlling the display of documents such as characters and symbols that have been rekeyed, and a cursor, etc., on the display device e. d is key input means a
This is a document storage means for storing documents such as character strings input using keys.

As shown in FIG. 1, when a document such as characters is input by the key input means a, the document is stored in the document storage means d. When the decimal tab key DTK is input, the cursor is moved by the cursor control means 1 and the result is outputted on the display e by the display control means C.

FIG. 2 shows another embodiment of the character processing device of the present invention.

In the configuration shown in FIG. 2, C'PU is a microprocessor that performs calculations and logical judgments for character processing.
Via address bus 8B, control bus C[l and data bus DB, each component connected to these buses is controlled.

The KB is a keyboard on which various keys are arranged for inputting characters, symbols, etc., and key inputs for instructing various functions of character processing for these key inputs.

The address bus 8B transfers address signals indicating the components to be controlled by the microprocessor CPU. Control bus CB is microprocessor C
Control signals for each component to be controlled by the PU are exchanged with each of these components. The data bus DB transfers data between each component.

The ROM is a read-only memory, and stores in advance control procedures by the microprocessor CP II, such as the control procedure shown in FIG. 4.

The RAM is a random access memory and is used to temporarily store various data from each component. In this memory RAM, TBB is a tab position buffer, and stores the number of digits of the set tab position.

DBυF is a document buffer and stores data to be displayed on a display device CRT such as a cathode ray tube or liquid crystal display.

CTR is a cursor movement direction register that stores the specified cursor movement direction.

DISK is a memory for storing standard documents,
It is assumed that created documents are managed and saved documents can be called up by instructions from the keyboard KB.

CR is the cursor register. The contents of the cursor register CR can be read and written under control from the microprocessor CPU. xCR is a cursor column register and stores the cursor column source. YCR is a cursor row register and stores the row coordinates of the cursor.

EnF is a buffer memory and stores character information etc. input from the keyboard KB.

CIITC is a CIIT controller, and under its control, the cursor register CR and document buffer DB
The contents stored in 11F are displayed on the display CRT.

CG is a character generator, and the display CR
It generates character signals such as letters, symbols, and cursors to be displayed on the T.

Figure 3 shows the decimal tab key D on the wood flow side.
An example of the operation when TK is pressed is shown. In the Kino style, the document buffer DBIIF has a size of, for example, 15 characters x 9 lines, and the contents of this document memory DBIIF are outputted on the display RyCRT in the same positional relationship. Here, it is assumed that the tab position is set to 2°5.9.13 digits.

Now, when the cursor is at the position of ■ in the 2nd column of the 4th row, if the decimal tab key DTK is input, the cursor will move to 4
Move to the position marked ■ in the 5th column of the row. However, since there is a ruled line at the position marked ■, the cursor is automatically moved to the next tab position, the position marked ■ at the 9th column of the 4th row.

Figure 4 shows the decimal tab key DT on the wood flow side.
Flowchart 1 showing an example of a control procedure for processing when K is pressed
・It is.

The keys entered from the keyboard KB are decimal, tab,
If the key is DTK, the routine shown in FIG. 4 is started, and first, in step Sl, the currently displayed cursor is erased. Since the method of displaying and erasing the cursor can be realized using known techniques, a detailed explanation thereof will be omitted here.

In the next step S2, the current cursor digit register XC
A tab position with a value larger than and closest to the value of R is searched in the tab position buffer TBB.

In the next step S3, when it is determined that there is no such tab position, the process proceeds to step S4, where 1 is added to the cursor line register YGR, and then step S3 is performed again.
Return to step 2 and repeat the same tab position search process.

If it is determined in step S3 that there are two consecutive tab positions, the process proceeds to step s5, where the value of the tab position is assigned to the cursor column register XCR.

Then, in step s6, move the cursor to
According to R and the value of cursor row register YCR, display C
Display cursor on RT.

In the next step S7, the document memory DBII specified by the cursor column register XCR and the cursor row register YCR is
The contents of F are checked, and if it is a ruled line, the process returns to step s1 and the same process is repeated. On the other hand, if there is no ruled line in step s7, the process ends.

Note that although the case of decimal tabs has been shown on the Kinotsu style side, similar processing can be implemented for other tabs.

Also, when there is a ruled line on a tab position, instead of moving the cursor to the next tab position as described above, it is of course possible to move it to another predetermined position, such as one character before. It is.

〔Effect of the invention〕

As is clear from the above, according to the present invention, the decimal
When using tabs, even if there is a ruled line at the destination of the cursor movement, the cursor is automatically moved to remove the ruled line position, allowing quick processing.
