The DB transfers and receives data between each component.

Next, the ROM is a read-only fixed memory device that stores various control procedures etc. by the microprocessor CPU, which will be described later with reference to FIGS. 4 and 5.
It is a writable random access memory with a 16-bit word structure and is used for temporary storage of various data from each component, and the KB is a keyboard that is used to input various data and give instructions to this character processing device. For example, various key groups for providing the information are arranged as shown in FIG.

In the configuration of the keyboard KB shown in Figure 2, CIK is a group of various keys such as character keys and function keys for character processing, and HK indicates the range of input strings in kana-kanji conversion or work instructions. It is a range key.

Next, the CR in the overall configuration shown in the first diagram is
A cursor register and a microprocessor register.
A memory device that is controlled by the CPU and used to write and read data related to the cursor position.
Under the control of the CRT controller CRTC, the cursor is moved to the display position on the CRT display surface corresponding to the address stored in the cursor register CR. Also, DBUF is a data buffer memory, which is a memory device for storing text information entered from the keyboard KB.
The text information stored in this data buffer memory DBUF by the controller CRTC is displayed on the display device.
Display on the CRT display screen. Note that this data buffer memory DBUF is used as a refresh memory for the display device CRT, and can be arbitrarily written and read by the microprocessor CPU.

Next, the CRT controller CRTC controls the cursor register CR and data buffer memory.
The display of the cursor and display pattern on the display surface of the display device CRT is controlled based on the cursor position and character code signals respectively stored in the DBUF. In addition, CRT is a display device that uses a cathode ray tube, etc.
The dot configuration display pattern and cursor display on the CRT are controlled by the CRT controller CRTC. Further, the CG is a character generator, which generates character signals such as a cursor to be displayed on the display device CRT, and each character has a dot configuration of, for example, 16×16.

Next, an outline of the operation of the character processing apparatus of the present invention having the above-described structure will be explained with reference to FIGS. 3A, B, and C. Note that key operations related to the operation of the character processing device of the present invention are performed using character keys and function keys arranged on the keyboard KB.

First, when the power is turned on, the cursor is placed on the display screen of the display device CRT, as shown in Figure 3A.
The CM is simply displayed at the top left corner, and the result of the character processing operation described below can be displayed. That is, when performing kana-kanji conversion in the character processing device of the present invention, the hiragana character string to be converted to kanji is entered using the range specification key.
It is necessary to enter the input while holding the front and back of the HK, and when the range specification key HK is pressed, the range is specified in the monitor area provided at the bottom row of the CRT display screen, as shown in Figure 3 A and C. The mark "*" appears, followed by the hiragana character string to be converted to kanji,
For example, as shown in Figure 3A, if you input "KIGO" and then press the range specification key HK, the hiragana character string "KIGO" will be displayed with range specification marks "*" placed before and after it. appear in the area. After that, the hiragana character string "Kigou"
Convert to kanji and move the cursor shown in Figure 3A.
At the same time as the CM is displayed, the cursor CM automatically advances to the position where the next kanji should be displayed, as shown in Figure B, and the above-mentioned input hiragana character string is displayed in the monitor area. 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, the predetermined command name is written as a katakana character string, following the same input procedure as in the above-mentioned kana-kanji conversion. It can be carried out. That is, in the case where the character processing device of the present invention is equipped with a calculation function, for example, in order to perform calculation work by command, first press the range indication key HK, as shown in FIG. 3C. and enter the range indication mark "*", then enter the command name "Keisan" in katakana character string, and then press the commad key "," to add a delimiter, the katakana character string entered up to that point will be is treated as a command name.
Furthermore, after inputting "1+2" as a necessary parameter for "Keisan", press the range indication key HK again and input the range indication mark "*", then "Keisan, 1+2" will be 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, an example of a character processing operation performed by the apparatus of the present invention will be explained with reference to FIG. 4 and FIGS. 5A and 5B.

First, in the flowchart shown in Figure 4, in step S1 prior to the start of operation, the key operation standby state is maintained, and when some key operation is performed, in step 2, the first key input is the range instruction key.
Determine whether or not it is a range indication mark* by pressing HK. If the first key input is a range indication mark, process 1 is performed in step S3, and if the first key input is not a range indication mark, process 2 is performed in step S4. When these processes 1 and 2 are completed, the process returns to the state of waiting for key input in step S1.

Next, when performing process 1 according to the flowchart shown in FIG. 5A, first, in step S1,
Examine the memory contents of the data buffer memory DBUF, which corresponds to the monitor area on the CRT display screen, and
It is determined whether the code signal of the range indication mark * has already been input and stored, and if the code signal of the range indication mark * has already been input, in step S2, the code signal subsequent to the range indication mark * is determined. Check the next character code, and if the character code is for hiragana characters, perform character processing for kana-kanji conversion in S3, and if the stored input character code is not for hiragana characters,
In step S4, character processing is performed by command operation. However, in step S2, 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 S5, the code signal is moved to the top position of the monitor area on the CRT display screen again. The code signal of the range indication mark is stored in the corresponding address of the data buffer memory DBUF by key operation.

Next, when performing process 2 according to the flowchart shown in FIG. 5B, first in step S1,
The stored contents of the data buffer memory DBUF corresponding to the monitor area of the CRT display screen are checked to determine whether the code signal of the range indication mark * has already been input, and the code signal of the range indication mark * has already been input. When the step
At S2, the character code of the input key signal is stored in a predetermined storage location of the data buffer memory DBUF corresponding to the CRT display screen and monitor area, and is also displayed in the monitor area. When is not entered,
At step S3, the cursor CM on the CRT display screen
The character code of the input key is stored in the storage location of the data buffer memory DBUF corresponding to the location specified by .
