Abstract

PURPOSE:To automatically expand or contract the display of an input character by reading out a pattern detected by a detecting means for detecting a result obtained by converting an input character string into a word notation and corresponding to the strength of depressing force from a pattern storing means and displaying the read contents. CONSTITUTION:The strength of depression force obtained at the time of inputting a word is decided by an input means KB for inputting the reading of words, the depressed key and its depressing level are transferred to a microprocessor (CPU) through a data bus(DB) and a depressing level signal is stored in a depressing level buffer ORBUF in a writable random access memory(RAM). At the time of word conversion, the CPU inputs the value of the ORBUF which is obtained at key input, decides whether the value is larger than the level of reference depressing force or not, reads out characters to be displayed from the pattern storage means CG, and displays the read contents on a display means CRT by changing the size of the characters. Consequently, display size can be automatically changed in accordance with an input depression level sent from a keyboard(KB).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device that inputs characters while performing kana-kanji conversion and creates and edits documents such as Japanese documents.

[Prior Art] In character processing devices that input Japanese characters, it is common to input characters using kana-kanji conversion. Normally,
Even if you change the strength of the pressure applied to the keys, the displayed characters and symbols will not change in any way.

[Problems to be Solved by the Invention] In the conventional method described above, when an inputter attempts to manually change the size of characters or symbols, the inputter must reset the size of the input characters each time. No. The more different the font sizes are in the input text, the more complicated the task becomes.

Therefore, if input characters can be automatically displayed in a larger or smaller size without the input person having to reconfigure the input character settings, the complexity of the f-work can be prevented. No such five-character processing device has been found.

[Means for solving the problem (and operation)] According to the character processing device according to the present invention, the word d.

By having the input means that inputs everything determine whether or not the pressing force is removed when inputting a word, it is possible to make the input characters appear larger,
You can now display it in a smaller size. For example, if you enter "Hana" with a strong pressure, it will be displayed as "Cma na'", and if you enter with a weak pressure (and enter it), "Hana" will be displayed. can.

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

FIG. 1 shows an example of the overall configuration of the present invention. In the illustrated configuration, the CPU is a microprocessor that performs calculations for character processing, logical judgments, etc.
Each component connected to the control bus CB and data bus DB is controlled via the control bus CB and data bus DB.

Address bus AB transfers address signals indicating the components to be controlled by microprocessor CP[J. Control bus CB is microprocessor CPU
A control signal for each component to be controlled is transferred and applied. The data bus DB transfers data between each component device. For example, a pressure level control signal is transferred from the keyboard KB to the microprocessor-CPU via the data bus DB.

Next, ROM is a read-only fixed memory, and the fourth
The control procedure and word dictionary by the microprocessor CPU, which will be described later, are stored in FIGS. The word dictionary is
"Yomi", "notation", and "grammatical information" are stored in correspondence, and are referenced in kana-kanji conversion, etc.

Further, the RAM is a writable random access memory with a configuration of 1 word and 16 bits, and is used for temporary storage of various data from each component.

In the RAM, TBUF is a text buffer, which is an area for storing document data to be created and edited as will be described later in FIG.

DBIND is an area that stores an index of the homophone buffer area.

DBBDY is the main body of the homophone buffer area, as will be described later.

KBBUF is a keyboard buffer for storing input reading strings.

0RBUF is a pressure level buffer and is an area for storing pressure level signals sent from the keyboard.

KB is a keyboard, which includes a pressure sensor, alphabet keys, hiragana keys, katakana keys, and other character/symbol keys 1, as well as conversion keys and other various functions for instructing the character processing device to perform various functions. The pressed key and pressing level are transferred to the CPU via the DB, and the pressed key code and pressing level are also stored in the RAM.

DISK is an external storage unit for storing document data, and stores created documents on the text buffer TBUF.
Called when needed.

CR is a cursor register. The CPU can read and write the contents of the cursor register.

A CRT controller CRTC, which will be described later, displays a cursor at a position on the display device CRT corresponding to the address stored here.

DBUF is a display buffer memory that stores each data pattern to be displayed according to the pressure level signal sent from the keyboard. When displaying the contents of document data, D is displayed based on the data on the text buffer TBUF.
This is done by developing a pattern on the BUF.

CRTC is cursor register CR and buffer DBUF
It plays the role of displaying the contents stored in the CRT on the display device CRT.

Further, a CRT is a display device using a cathode ray tube or the like, and the display of a dot configuration pattern and a cursor on the display device CRT is controlled by a CRT controller.

Furthermore, CG is a character generator that stores patterns of characters and symbols to be displayed on the display device CRT. In addition to standard character patterns, this CG also stores character and symbol patterns depending on the pressing level.

The character processing device of the present invention, which is composed of each of these components, operates in response to various inputs from the keyboard KB, and when input from the keyboard KB is supplied, an interwoven signal is first sent to the microprocessor CP.
The microprocessor CPU reads various control signals stored in the ROM, and various controls are performed in accordance with these control signals.

FIG. 2 is a diagram showing an example of operation of the character processing device of the present invention.

In the figure, CRT means a display screen.

CM is a cursor, and the next time you press the key,
This indicates the position where the character will enter.

TS is the text screen, text buffer TBUF
The content of the document stored in is displayed.

MS is a monitor line, which is an area where input key data is displayed one by one. When performing kana-kanji conversion, the reading sequence is displayed on -HMS, and after conversion, the conversion result is transferred to the TS.

FIG. 2(a) is a diagram showing a display form when inputting with a standard pressing force and converting kana-kanji.

First, the operator tries to convert ``Hana'' into Kana-Kanji in a text buffer, and manually presses the ``Hana'' key with the standard pressing force, and then inputs the Kana-Kanji conversion key ``/''.

"Hana/" is converted into kana-kanji and becomes "hana" in the text screen (.

FIG. 2(b) is a diagram showing the display form when inputting with a strong pressing force causes kana-kanji conversion.

The operator presses the text buffer with a force stronger than standard.
Enter the "Hana" key manually, and then enter the Kana-Kanji conversion key "/". "Hana/" is converted into kana-kanji and becomes "6 years old"
This will take you to a text screen.

FIG. 2(C) is a diagram showing a display form when the pressing force is weakened to convert input into kana and kanji.

The operator presses the text buffer with a pressure that is weaker than the standard.
Enter the "Hana" key manually, and then enter the Kana-Kanji conversion key "/". "Hana/" is converted into kana-kanji and becomes "hana" and enters the text screen.

FIG. 3 shows the structure of the dictionary in the present invention.

The words are “yomi” (20 characters), which is a sequence of words,
The notation of the “reading” is “notation J (20
character), it has ``grammatical information'' (10 characters) that indicates the grammatical information of that ``notation''.

FIG. 4 is a diagram showing the configuration of the keyboard buffer KBBF.

The key data entered from the keyboard is -tanko KB
0 stored in BF For example, in the case of kana-kanji conversion, the information of the reading sequence is stored in this KBBF until the conversion conditions are met, and when the conversion conditions are met, it is converted to kanji and the back is cleared. For example, the characters are JIS X 020
Each character is stored as 2 bytes using the g code. In the figure, "/" means a kana-kanji conversion key, which means that the reading string stored up to "/" is converted to kanji.

FIG. 5 is a diagram showing the configuration of the pressure level buffer 0RBF.

Stores the pressure level signal sent from the keyboard.

The larger the number, the stronger the pressing force.

FIG. 6 is a diagram showing the overall structure of a text buffer TBUF that stores the contents of document data that is being created and edited.

FIG. 6(a) is a diagram showing the overall configuration of the TBUF.

Documents are stored as sequences of characters.

FIG. 6(b) is a diagram showing the structure of each character.

One character consists of 2 bytes. MSB (2' bit) is the homophone accent level, and the remaining? The part (21
4-2° bit) is J in the chord part. Homophone accent level indicates whether the character is in the same word or a regular character; "o" is a regular character, "1" is a homonym, and 0 is a regular character. The character code is stored in the code section as a JIS X 0208 code. When the words are homophones, the homophone number is stored in the C-code section. The homophone number serves as an index in the index section of the homophone buffer area, which will be described later, and allows you to point to a specific homophone buffer.

FIG. 7 is a flowchart of the part that takes in key human power and performs processing.

Step 7-1 is a process of importing data from the keyboard into the buffer KBBUF.

Hereinafter, the process branches as follows depending on the type of key existing in KBBUF. When KBBUF contains data for a Kana-Kanji b character conversion key, Kana-Kanji conversion must be performed, and the process branches to Step 7-2.
Display the "Table" which is the result of the conversion in step 4. Otherwise, in step 7-53, other processing such as cursor movement, insertion, deletion, etc., which is found in a general character processing device, is performed.

, Figure 8 shows the "display" of step 7-4 in Figure 7.
This is a detailed flowchart.

In step 8-1, the value of the key press level buffer when the key is pressed manually is read, and in step 8-2, the value is determined to be greater than the standard press force level (for example, set in advance as level "5"). The size of the characters to be displayed is changed and displayed in steps 8-3 to 8-5.

In this case, large, standard, and small character patterns are read out from the CG and displayed.

Figure 9 shows "Kana-Kanji conversion" in step 7-2 of Figure 7.
This is a detailed flowchart.

In step 9-1, the input pronunciation and accent information for each sound are compared with a word dictionary to create conversion candidates. Furthermore, it determines which of these conversion candidates is most likely, sets the input pronunciation and accent information for each sound in the homophone buffer, and creates conversion candidates. Then, the most plausible word is determined as the first candidate. In step 9-2, homophones are created based on the determined first candidate. The created homophone buffer is looked at and output in step 9-3.

[Other Examples] In the above explanation, the display size was changed according to the input pressure level sent from the keyboard, but the display size was also divided into three levels: large, medium, and small. Prepare a plurality of patterns for each data to be displayed according to the pressure level signal sent from the keyboard, which is not limited to this, and select a pattern according to the pressure level from among them.
It is also possible to display the pattern.

[Effects of the Invention] As is clear from the above description, according to the present invention, conventionally it has not been possible to reflect the size of characters intended by the inputter when converting words. However, by using this method to reflect the input person's intention in the kana-kanji conversion, it becomes possible to perform the kana-kanji conversion with higher accuracy.
