The operation of the embodiment having the above configuration will be explained according to the control flow shown in FIGS. 2 to 5.

When the power is turned on, the internal state of the device is in its initial state. In particular, the memory according to the present invention
In the RAM mode register RAM1, a signal indicating automatic conversion is set as an initial state signal. Mode register RAM1 includes the aforementioned mode key automatic conversion key KB2, Onkun input key KB3, registered kanji call key KB4, and code input key KB.
When each of the 5 and 2-stroke keys KB6 is operated, the corresponding key code signals are stored.

Assuming that automatic conversion key KB2 is operated now,
Control is performed according to the operation keys according to the control procedure stored in the control memory ROM. Now, when the automatic conversion key KB2 is operated, it is determined in step 1 shown in FIG. 2 that the key code is not a character code, and the process moves to step 2, which is an input mode switching key. This determination is made by comparing the key code with the code derived from the control memory ROM by the processor CPU.

The result is ``YES'' and the control moves to step 3. This step automatically converts the input data remaining in the memory RAM into Japanese text mixed with kanji and kana. There are many publicly known examples of this method.The meaning of this automatic conversion is to convert kana to kanji by inputting the reading kana that follows the flow of the sentence, and the result of this conversion is stored in the converted sentence buffer. However, in this case, there is no input data to be converted.
Next operated mode key, i.e. automatic conversion key KB
The key code corresponding to 2 is the mode register RAM
1 and returns to the standby state.

Next, when the character key KB1 is operated and Japanese text begins to be inputted, for example in the form of kana, first step 1 is entered.
Then, the processor CPU determines whether the operated key is a character code.

If the kana key KB1 has been operated, the answer is "YES" and control moves to step 5 in FIG. Details of step 5 are shown in FIG. To explain according to the figure, first, since the content of mode register RAM1 is automatic conversion mode, “YES” is selected in step 5a.
Then, control is performed to input the character code of the operation key in step 5aa into the automatic conversion buffer RAM 2, and the process moves to step 6. (Details are shown in Figures 3 and 4) First, the contents of mode register RAM1 are checked by the processor CPU, and since it is automatic conversion mode,
If the answer is ``YES'' in step 6a, the process jumps to ○A shown in Figure 5, and the processor CPU determines whether to start the conversion.
Determine by In this case, this discrimination criterion is determined by the number of kana data input to the automatic conversion buffer RAM 2, etc.

Therefore, if the answer to the question of whether to start conversion is "NO", the system enters a standby state waiting for a key, and if the answer is "YES", the contents of the automatic conversion buffer RAM 2 are transferred to the automatic conversion control procedure and its kanji table in the control memory ROM. Based on this, it is converted into a sentence containing kana and kanji, stored in the converted sentence buffer RAM 7, and enters a standby state.

Next, a case where the Onkun key KB3 is operated will be explained.

Onkun input described here is to input kanji one by one. Enter part or all of the onyomi or kunyomi of the desired kanji using the character key KB1, search the kanji table for the corresponding kanji, and display the list. , the user selects and inputs the desired kanji from among them.

First, when the Onkun key KB3 is operated, the judgment in step 1 in Fig. 2 is made, and in this case, the answer is "NO".
Therefore, the process moves to step 2, and since the input mode key has been operated, the process moves to step 3.
Here, the input data using the character key KB1, which was input before the onkun key KB3 was operated, is converted into a kana-kanji-mixed sentence by the kana-kanji automatic conversion control and is stored in the converted sentence buffer RAM7. Next, in step 4, the character code is stored in the mode register RAM1 by the on-kun key KB3, and a standby state is entered.

The input method in this mode is to input kana, alphanumeric characters, etc. as they are, and to input kanji characters expressed in kana by operating the kanji shift key KB7 back and forth. When direct input other than kanji (kana, alphanumeric characters, etc.) is entered, steps 1, 5, 6, and the steps in Figure 5 are entered.
At 6ba, it is determined that the kanji shift register RAM8 is not set and becomes “YES”.
The input data stored in the on-kun buffer RAM 3 is transferred to the converted sentence buffer RAM 7.

When the kanji shift key KB7 is operated, the process moves to steps 1, 2, and 7, and in step 7 it is determined whether the kanji shift key KB7 has been operated, and "YES" is selected.
Then, proceed to step 8.

At step 8, the contents of the kanji shift register RAM8 are determined by the processor CPU, and in this case, the result is "NO", and the process moves to step 9, where the kanji shift register RAM8 is set and the onkun buffer is set.
Store the kanji start code in RAM3 and step 11
Move to. Step 11 is the same as step 6, and in this case the kanji shift register has been set, so the process moves directly to the standby state.

Next, when the character key KB1 is operated, the kana data is stored in the phonetic buffer RAM3 through steps 1, 5, and 6. Then press the kanji shift key
When KB7 is operated, steps 1, 2, 7, 8
Then, at step 8, the processor CPU returns "YES" because the kanji shift register RAM8 has been set, and moves to step 8, where the kanji shift register RAM8 is set.
Input the kanji end code into RAM3 following the kana data, and reset the kanji shift register RAM8.

Next, move on to step 14. Step 14 is the same as step 6, and if you say “YES” in step 6b,
Moving to step 6ba, it is determined whether conversion should be started based on the key of the kanji shift register RAM8, and since it has now been reset, the result is "YES" and the step is started.
6bb, based on the onkun conversion control procedure stored in the control memory ROM and its kanji table, the corresponding kanji is derived from the kanji table using the kana data sandwiched between the kanji start code and the kanji end code as an index, and the converted sentence buffer is derived. Put it in RAM7. In this state, the cursor is moved, which is a function of a normal character processing device. Place the cursor at the desired kanji position. The contents of the conversion text buffer RAM7 are input to the memory DM by the display controller DRC,
Displayed on CRT device DP. Therefore, when the cursor is moved, such control is performed in steps 1, 2,
After 7, 1, and 5, it is performed at step 15,
When a selection key (not shown) is operated during this control, one corresponding kanji can be selected, and the processor controls the control to leave the kanji in the converted text buffer RAM 7.
Performed by CPU.

Next, a description will be given of what happens when the registration call key KB4 is operated. In advance, in the control of step 15,
Text to call up the registration buffer RAM9 again,
The following explanation assumes that data such as phrases and words are stored. The registration call key KB4 is used to call up the data as described above, and in almost the same way as the above-mentioned phonetic input, by performing key operations in the order of "Kanji shift", "Index to call up registered word", and "Kanji shift". , the registration data stored in the registration buffer RAM 9 is called; in this case, the index is stored in the registration call buffer RAM 4.

Next, we will explain how to input kanji using code input.

When the code input key KB5 is operated, control is performed as shown in FIGS. 2 to 5, and the mode is set. In this mode, for example, a kanji is input using a kanji code assigned to a kanji defined by JIS.
The numerical value of the digit is entered, and of course the kanji shift key is used before and after.
When the KB7 is operated, as shown in Figures 2 to 4, the four-digit number held in the shift key serves as an index, and the kanji table stored in the control memory ROM along with the code input procedure is referred to. is derived and stored in the converted sentence buffer RAM 7.

Next, the two-stroke input key KB6 will be explained.

This input method basically selects one kanji by pressing the character key on the keyboard KB1 twice, and if there are 50 character keys, 50 x 50 =
2500, it is basically possible to input characters. Of course, it is obvious that expansion can be easily done by combining the shift keys.

When the "2-stroke input" key is pressed, the mode register
When RAM1 is in the state of "2-stroke input" and the "Kanji shift" key KB7 is pressed, pressing the character key KB1 will cause the 2-stroke input buffer RAM6
can be placed in When two codes of the character key KB1 are entered in the 2-stroke input buffer RAM6, the control memory
Using the ROM's two-stroke input control procedure, the kanji characters specified by these two character codes are sequentially input into the converted text buffer RAM 7 from the kanji table. Examples of input are "Kanji shift", "i", "a", "ka,"
When entering ``sa'', ``to'', and ``me'', the kanji that corresponds to ia, such as ``light'', is entered into the conversion sentence buffer RAM7, and then the kanji that corresponds to kasa, such as ``ko'', is entered into the conversion sentence buffer RAM7. enter. Here are the steps
The conversion condition for 6ea is determined by determining whether or not it has been hit twice.

In all of the above, as is clear from the flow, when the input mode key is pressed, the data remaining in the special conversion buffer is forcibly converted into kana-kanji and stored in the converted text buffer RAM 7. . In addition, automatic conversion buffer RAM 2, Onkun input buffer RAM 3, registration call buffer
After the data in RAM 4, code input buffer RAM 5, and 2-stroke input buffer RAM 6 are converted, the converted portions are cleared. The data entered into the conversion buffer RAM 7 is displayed on the CRT device DP under various controls in step 15, and is also printed out to the printer P, output to the magnetic disk MD, or converted from the magnetic disk MD. Loading to buffer RAM7,
Data conversion from the conversion text buffer RAM 7 to the communication line can also be performed. Moreover, the various controls satisfy the functions of a general character processing device.
