Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to a document creation device based on editing full-width characters.

(Prior Art) In a document creation device based on full-width characters for editing,
Conventionally, when a document containing both half-width and full-width characters is created, the cursor indicating the next character input position is changed from half-size to full-size in accordance with the rules shown in FIGS. 3 (a) and 3 (b). I have. That is, FIG. 3A shows a state in which the cursor is switched to full-width when the cursor is at the left half-angle position, and FIG.
Indicates the state of switching to full-width when the cursor is at the right half-angle position.

However, if only the change based on this rule is used, if the cursor size is changed to full-width when trying to enter full-width characters after inputting an odd number of half-width characters, if full-width characters are input as they are, the same full-width characters will be entered last There is a drawback that the half-width character is overwritten on one half-width character and the already-entered half-width character is lost.

Specific examples are shown in FIGS. 5 (a) to (d).
Here, a case is shown in which, after inputting "abc" in one-byte characters and operating the "Hiragana" shift key to input "a", "a" is input in the digit position of the last input "c" in one-byte characters. Is overwritten, and “c” is erased.

(Problems to be Solved by the Invention) As described above, in the related art, when the cursor size is switched to full-width by a function key operation after inputting an odd number of half-width characters, if a full-width character is input in that state, the input is performed. There is a disadvantage that the last half-width character that has already been erased is erased.

The present invention has been made in view of the above circumstances, and eliminates the inconvenience that the last half-width character that has been input is lost when the cursor size is switched from half-width to full-width, and half-width and full-width characters are mixed. It is an object of the present invention to provide a document creating apparatus capable of executing a document input operation smoothly without any awareness of a cursor position.

[Structure of the Invention] (Means and Action for Solving the Problems) According to the present invention, a cursor indicating an input position of a half-width character is at a right half-width position, and the cursor is switched from a half-width size to a full-width size by operating a function key. It has means for recognizing that it will change and updating the cursor display digit when recognizing the same state,
Eliminates the inconvenience of erasing the last half-width character entered when the cursor size is changed from half-width to full-width, making it possible to efficiently and smoothly perform input work on documents containing both half-width and full-width characters It is.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a basic configuration of the document creating apparatus according to the above embodiment.

In FIG. 1, 10 is a microprocessor (CPU), 1
1 is a RAM accessed by the microprocessor 10,
12 is the ROM.

A microprocessor (hereinafter referred to as a CPU) 10 controls the entire apparatus, accesses the RAM 11 and the ROM 12, activates a program in accordance with an input instruction, and executes a document creation process, an external character creation process, and FIG. The key input control processing shown in FIG. The RAM 11 includes a document area, a line image area (print buffer), an external character registration area, a word registration area, and an area for storing control information such as a cursor position register for storing a cursor position on a document display screen. The ROM 12 includes a program area 13 storing a program for determining the operation of the CPU 10 and an input processing program including a cursor control routine associated with key input as shown in FIG. 2, and a character for storing a display or print character pattern and the like. It has a pattern area 14, a dictionary area 15 in which various dictionaries for converting readings input in kana or romaji into kanji are registered.

16 is a keyboard (KB), 18 is a display, 21 is a floppy disk drive (FDD), and 23 is a printer (PRT). A keyboard (KB) 16 receives input information necessary for document creation and the like via a keyboard interface (KB-IF) 17.
Input to CPU10. This keyboard 16 has character keys,
In addition to the cursor keys, various keys including a half-width designation key for switching the cursor range from full-width to half-width, and a "Hiragana" shift key, a "Katakana" shift key, a "Kanji" shift key, etc., which involve switching from a half-width to a full-width for the cursor range. Function keys are provided. The display 18 is composed of, for example, a 10-line liquid crystal display device. The display controller (display-CNT) 19 controls the display of the display 18 using the display dot memory 20 under the control of the CPU 10. The floppy disk device 21 stores a created document and stores external characters and second-level characters under the control of the CPU 10 via a disk interface (FDD-IF) 22. The printer 23 has a printer face (PRT-IF) 24
Under the control of the CPU 10 via the CPU 10, the created document or character information read into the main body from the floppy disk device 21 is printed.

FIG. 2 is a flowchart showing a key input processing flow according to the embodiment.

FIGS. 3 (a) and 3 (b) are diagrams for explaining the rules for changing the cursor size, and FIGS. 4 (a) to (d) are diagrams for explaining the operation in the above embodiment.

Here, the operation in one embodiment of the present invention will be described with reference to FIGS. 1 to 4.

When a key on the keyboard 16 is operated, a key input processing routine as shown in FIG.
It is executed under the control of 0. Here, first, it is determined whether or not the operation key is a function key such as a "Hiragana" shift key, a "Katakana" shift key, or a "Kanji" shift key which requires switching from a half-width to a full-width cursor. If not, the key input information is temporarily stored in the one-character buffer, and processing unique to the key is executed (steps S1, S2, S8, S9 in FIG. 2).

At this time, if the operated key is, for example, a “half-width key” for designating half-width character input, the cursor switches from a full-width size to a half-size size. The position (left half-width / right half-width) is stored in the cursor control register, and the display of the half-width cursor is controlled according to the contents.

In addition, the operated key needs to switch from a half-width to a full-width of a cursor, for example, a “Hiragana” shift key,
If it is a function key such as the "Katakata" shift key or the "Kanji" shift key, it is then determined whether the half-width cursor position is at the right half-width position. From the key input information stored in the buffer, it is determined whether or not the previously operated key is character data such as characters, numbers, and symbols or function keys (steps S1 to S4 in FIG. 2).

Here, when the half-width cursor position is at the right half-width position and the previous operation key is the data key, the cursor position is updated to the next digit (+1), the cursor size is switched from half-width to full-width, and the same size is updated. A cursor is displayed at the digit position in full size (steps S5 to S7 in FIG. 2).

When the half-width cursor position is not at the right half-width position (when it is at the left half-width position) or when the previous operation key is a function key, the cursor position is not updated, and the cursor size is changed from the half-width position at the digit position. The mode is switched to full-width, and a cursor is displayed at the same digit position in full-width size (steps S3, S4, S6, S7 in FIG. 2).

FIG. 4 shows a specific operation example according to the above embodiment.

Here, as in the case of the above-described conventional example, an example is described in which "abc" is input in half-width and then "a" is input in full-width.

In the conventional cursor control means shown in FIG.
When an odd half-width character string is input due to the cursor size changing rule shown in FIG. 3, the last input half-width character "c" may be erased. On the other hand, in the key input control means according to the embodiment of the present invention described above, as shown in FIGS. 4 (a) to 4 (d), when the cursor is at the right half-width position, the "Hiragana" shift key is pressed. Even if the full-width character "A" is entered as it is,
Since the cursor automatically moves to the next digit and the position of the next input character digit is updated, there is no danger that the half-width character "c" that was previously input will be erased. Can smoothly and quickly execute input of a document including half-width characters without error, without being aware of the cursor position.

Further, in the above-described embodiment, since it is checked whether the previously input key is a data key or a function key, even when the cursor size is changed after moving the cursor with a function key such as a cursor key, The inconvenience that the cursor moves excessively does not occur.

[Effects of the Invention] As described in detail above, according to the present invention, in a document creation device based on full-width characters for editing, the cursor is at the right half-width position, and the cursor is switched from half-width size to full-width size. Means for judging the change, and means for updating the cursor display digit at the time of the judgment, so that the last half-width character already input when the cursor size is switched from half-width to full-width Can be eliminated, and the input operation of a document in which half-width characters and full-width characters are mixed can be smoothly executed without being aware of the cursor position.
