Description

[Detailed Description of the Invention] The present invention aims to provide a character processing device capable of performing a kana-kanji conversion operation that converts a character string input in hiragana characters into kanji, and to combine the operation of kana-kanji conversion with other operations. Switching can be easily and reliably performed by a simple operation.

Conventional character processing devices of this type include a kana-kanji conversion means for converting an input plain name character string into kanji, a collection of input character strings, and operations such as searching, which are performed in response to the input of a command consisting of multiple characters. However, these two means are not necessarily provided separately in a systematically unified state, and therefore, in conventional character processing devices of this type, the input The disadvantage was that there was no systematic uniformity in the system.1 For example, when entering a command, various information such as parameters accompanying the command are also entered, so when switching to command mode, the K For example, it was necessary to switch the display screen.

An object of the present invention is to eliminate the above-mentioned drawbacks of the conventional technology, and to make it possible to perform input operations in the same manner without changing the operation mode in both kana-kanji conversion work and command instruction work. The objective is to provide a 5K character processing device that can be reliably and easily switched.

That is, the present invention enables the above-mentioned object to be achieved by changing the types of characters in the character string input to the two-character processing device according to the content of the work.

The invention will now be described in detail with reference to one aspect.

First, an example of the overall configuration of the character processing device of the present invention is shown in FIG. 1. In the configuration shown in FIG.
That is, it is a so-called microprocessor, which performs arithmetic operations for character processing, logic judgment 1it-F, address bus AB, control bus Cl, and data bus DB.
t, respectively, to control each component connected to those buses. Also.

Among these buses, that is, signal lines common to each component, the address bus AB transmits address signals that specify the component to be controlled by the microprocessor CPU, and the control bus CB! It transmits and applies all control signals to each component to be controlled by the microprocessor CPH, and also transfers and receives data between each component in the data node (DIG) family.

Next, the ROM is a read-only fixed memory device that stores all the various control procedures by the microprocessor CPU, which will be described later with reference to W4*h and Figure j. A writable random access memory with a word configuration of 14 bits, which is used for temporary storage of various data from each component,
Furthermore, KB is a keyboard, and a group of various keys for inputting various data and giving instructions to this character escape device, such as #! They are arranged as shown in Figure 1.

In the configuration arrangement of the keyboard Kn shown in FIG.
K is a group of various keys including character keys and function keys for character processing, and K is a range key for instructing the range of input character strings in kana-kanji conversion or work instructions.

Next, CR in the overall configuration shown in No. 1 is a cursor register, and is a data pipe write register which controls the cursor position K14i by the microprocessor CPU K.
It is a memory device for reading, and is a CRT Coytrotz C
Under the control of the RTC, the cursor is moved to the display position on the CRT display surface corresponding to the address stored in the cursor register CR. In addition, DBUP is a data backup memory, which is a memory device for storing text information entered from the keyboard KB.
The text information stored in the data backup memory DBUP is displayed on the display surface of the t-display device CRT by the l'controller CR'l'CK. Note that this data buffer memory DISUF is used as a glue memory for the display device CIL'l', and is used by the microprocessor CPU.
It is assumed that it is possible to write and continue writing as desired.

Next, the CRT controller CRTC controls the display of cursors and display patterns on the display surface of the display device CRT based on the cursor position and character code signals stored in the cursor register CR and data backup memory DBUP, respectively. . Also, C
B'l' is a display device using a cathode ray tube.
The dot-configuration display pattern and cursor display on the display device CR'l' are controlled by the CR1 controller CR'l'.
Controlled by C. Furthermore, CG is a character generator that generates character signals such as a cursor to be displayed on the display device CRT, and each character is formed of, for example, 76×/4 dots.

Next, the operation of the character processing apparatus of the present invention having the above-described structure will be schematically shown in FIGS.
Refer to li2 for details. Note that the key operations related to the operation of the character processing device of the present invention are performed using the character keys and the funky key located on the keyboard Nil. First, when the power is turned on, #! is displayed on the display surface of the display device CB'l'. As shown in Figure 3 (mu), the cursor CM
is simply displayed at the top left corner, and the result of the character processing operation described below can be displayed. In other words, when performing kana-kanji conversion in the character processing device of the present invention, it is necessary to input the character string of the main plain name to be converted into kanji using the range specification key HK, sandwiching the front and back of the character string. When the key HKt- is pressed, the third

As shown in (C), specify the range in the monitor area provided at the bottom row of the CB'l' display screen! -ri1#" appears, and then the flat name character string 5 to be converted into kanji, for example #! After inputting "kigou" as shown in Figure 3 (mu), press the range specification key HK. Then, the flat name character string "Kigo" is in front of it? ! & appears in the monitor area with the range indication mark ``CK'' in between.

After that, convert the plain name character string "Kigou" into seven kanji and place it in the position of the carnol CM shown in Figure 97 (A).
As shown in B), at the same time as the display, the carnor CM is automatically advanced to the position where the next kanji character is to be displayed, and the display of the above-mentioned input flat character string in the monitor area is cleared.

Note that such input/output control and kana-kanji conversion processing can be easily performed using conventionally well-known techniques.

Next, when giving a specific work instruction using a command to the character processing device of the present invention, input the predetermined command name into a katakana character string, rC, and follow the same input procedure as in the above-mentioned kana-kanji conversion. be able to. That is, in the case where the character processing device of the present invention has a calculation function tfII1, for example, in order to perform calculation work by a command, as shown in FIG. and range indication mark -”
If you input seven characters and add a delimiter, the katakana character string input up to that point will be treated as the command name. moreover,"
Keisan JK After inputting "l+ko" as a necessary parameter, the user presses the range designation key B again and inputs the range designation mark 1.'', and "Keisan, /+ko" is processed as a command.

Note that various techniques have been disclosed regarding the actual calculation processing and its display mode, and it can be easily realized using well-known and commonly used techniques.

Next, two examples of character processing operations performed by the apparatus of the present invention will be described with reference to FIGS.

First, in the flowchart shown in Fig. 1, in step 8/ prior to the start of operation, the state is maintained in the middle operation standby state, and when some key operation is performed, the first key manually moves to the range indication key. Determine whether or not it is the range indication mark by pressing UK, and the first key human power is the range indication! - Step 8
3, and when the first key input is not a range indication mark, the process λ tube lights up in step evaluation, and when these processes l and ko are completed, the key input in step 8 is again executed. Return to standby state.

Next, when performing the process according to the two-chart shown in @ja (mu), first use the CRT
All the storage contents tm of the data backup memory DBUP corresponding to the monitor area on the display screen are marked with a range indication mark φ.
It is determined whether or not the code signal has already been input and stored, and if the code signal for range designation ff-ku has already been input, in step 8JK, the next character code following the range designation mark is determined. If the character code is a hiragana character, character processing for kana-kanji conversion is performed in %S3, and if the stored input character code is not a hiragana character, step 8
1K performs character processing using command operations. However,
If the code signal of the range indication mark does not exist in the stored contents of the data buffer memory DBUF corresponding to the monitor area in step 8j, then in step 8j the code signal is moved to the beginning position of the monitor area on the CR'l' display screen. The code signal of the range designation mark is stored in the corresponding address of the data buffer memory DBUF by key operation.

next,#! jr! ! ! When performing the processing according to the flowchart shown in JCB), first, in step 8/, all the stored contents of the data backup memory DBUP corresponding to the monitor area of the NCR'l' display screen are specified. Determine whether the code signal has already been input and indicate the range! If the code signal for ``-'' has already been manually input, in step 8, the data backup memory DB corresponding to the monitor area of the CRT display screen is
The character code of the input key signal is stored in a predetermined memory location of the UP and also displayed on the monitor area.If the code signal of the range indication mark is not input, in step 87, the character code of the input key signal is displayed on the CRT display screen. cursor commercial
Data buffer memory D corresponding to the location specified by
