Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a code input device for a computer or the like, in which a code input from a keyboard is stored in an input memory as a primary code string, and the contents of the input memory are used as a key. Search the code conversion table,
The present invention relates to an input device that converts into a desired secondary code string and stores it in a storage device, and includes a display device that displays the contents of the input primary code and the contents of the secondary code that is the result of the conversion.

[Background of the Invention] Codes input from a keyboard are stored in an input memory as a primary code string, and when a predetermined number of codes are input or a predetermined key is input, the primary code string input until then is stored. Therefore, there is an input device that searches a code conversion table, converts it into a corresponding secondary code string, and stores the secondary code string in a predetermined storage device as a desired code string. This type of input device is equipped with a display device that displays the primary code string that is the contents of the input memory, and also erases the primary code string after converting it into a secondary code string and displays the secondary code string that is the conversion result. , it is generally configured so that the input person can easily check the input contents and conversion results. This has a great effect for those with an average operating speed, as they can check input codes one by one while typing, allowing them to immediately spot input errors, but for experienced high-speed inputters, the display and conversion are very effective. Due to processing time constraints, the control unit could not respond even when a key was actually pressed, resulting in the input code being ignored.

Therefore, some devices are equipped with an input control section independent of the conversion processing section, store all input codes in the input memory, and when the conversion processing section finishes the processing, sequentially fetch the primary code string from the input memory and convert it. be. However, even with this device, there is a time delay from the time the input is entered on the keyboard until it is actually displayed and converted, which causes a significant decrease in operability for the inputter. Since the primary code string is displayed and erased, the displayed image flickers and has the drawback of putting a great strain on the eyes.

[Purpose of the invention]

An object of the present invention is to control whether or not to display the primary code string according to the input speed of the inputter, that is, to display the primary code string in the case of slow input, and to display the primary code string in the case of high speed input. By controlling the display so that the primary code string is not displayed, users who type at low speeds can input while checking the primary code string that they input, while users who type at high speeds can see the effect of realizing high-speed responsiveness. An object of the present invention is to provide a code input device with good operability that can accommodate the input speeds of various input users and reduce fatigue.

[Summary of the invention]

The present invention includes an input control unit that stores a primary code input from a keyboard in an input memory, and a converter that searches a code conversion table according to the primary code string and converts it into a desired secondary code string and stores it in a storage device. In an input device that has a processing section, it is possible to control whether or not to display the contents of the primary code on the display device based on the input speed of the primary code, specifically, the number of codes in the primary code string stored in the input memory. The primary code content display control means is provided.

[Embodiments of the invention]

Hereinafter, an embodiment in which the present invention is applied to a Japanese word processor will be described in detail.

FIG. 1 is a block diagram showing the basic configuration of a Japanese word processor. 1 is a keyboard operated by an inputter. Reference numeral 2 denotes an input control section which reads the code of a key pressed on the keyboard 1 and sets it in the input memory 3, as well as counts up an input counter 4. 5 is a conversion processing unit which takes in the code input from the input memory 3, converts it into a secondary code string by referring to the code conversion table 6 as a primary code string, and stores it in the storage device 7; The primary code string display flag is set, and codes are set in the primary code string display register 8 and the secondary code string display register 9.
Reference numeral 10 denotes a display control section, which displays the contents of the primary code string display register 8 and the secondary code string display register 9 on the display device 12.

The processing contents of the input control section 2 and the conversion processing section 5 will be explained with reference to FIGS. 2 and 3.

FIG. 2 is a processing flow of the input control section 2. First, in process 100, the input counter 4 is cleared to zero, and the process moves to process 101, waiting for a key on the keyboard 1 to be pressed. When the key is pressed, the process moves to process 102, stores the code in the input memory 3, and processes 10
After moving to step 3 and incrementing input counter 4 by 1, proceed to process 1.
Returns to 01 and waits for the next key input.

FIG. 3 is a processing flow of the conversion processing section 5. First, in process 200, the primary code string display flag is set to “1”.
After setting the mode to display the contents of the primary code, the process moves to step 201 and the input counter 4 is checked. If there is an input code, the process moves to process 202, where the code inputted first is fetched from the input memory 3, and the process moves to process 203, where the input counter 4 is set to "-1". Next, in process 204, the input counter 4 is checked again, and if the input counter 4 is "0", there is no input code waiting to be processed, so process 204 is performed.
Proceed to step 5 and check the primary code string display flag. As a result, if the primary code string display flag is "1", the process moves to step 206, where the retrieved primary code is set in the primary code string display register 8. If the primary code string display flag is "0" in process 205, it is not set. On the other hand, if the input counter 4 is not "0" in process 204, this indicates that the primary code input at high speed remains unprocessed, so the process moves to process 207 and sets the primary code string display flag to "0". 0” to set the mode in which the contents of the primary code are not displayed. Next, in step 208, it is determined whether the primary code string has become a conversion unit.
If it has not become a conversion unit, the next input is fetched and the process returns to start processing 201, and when it has become a conversion unit, the process moves to process 209 to search the code conversion table 6 according to the imported primary code string and convert it into a secondary code string. . Process the converted secondary code string 210
After setting the secondary code string display register 9 with
In process 211, the secondary code string is stored in the storage device 7, and in process 212, the primary code string display register 8 is stored.
Clear. Then, the process returns to process 200 at the beginning of the flow to process the next input code string.

The display control unit 10 displays the contents of the code strings thus set in the primary code string display register 8 and the secondary code string display register 9 on the display device 12.

Two specific display examples based on the above technique will be explained with reference to FIGS. 4 and 5.

The first specific example shown in FIG. 4 is an example of an input method (referred to as 2-stroke input) in which one character such as a kana, kanji, or symbol is encoded by assigning two kana characters. As shown in FIG. 4, when the primary code 300 "b" is input from the keyboard 1, it is temporarily stored, and then when "ha" is input, the two-stroke dictionary, which is the code conversion table 6, is stored. It is searched and converted into the secondary code 301 "tadashi" which corresponds to the primary code string "b" and "c". Here, the conversion unit is fixed at two primary code characters.

For a typical inputter, the input speed is approximately 40 strokes/
It is a quantile, and the average is 1.5 seconds / stroke. So the average is 1.5
The contents of the primary code are displayed every second, and the contents of the secondary code are displayed every three seconds on average, and the primary code string is erased. This speed is a speed that can be sufficiently followed by general processing devices and display devices using microprocessors, etc., and there is no delay in response to input, and eye fatigue due to repeated display and deletion is small.

But for a trained inputter, 400-500
The average speed is 0.12 to 0.15 seconds/stroke.
It is very difficult to perform conversion processing without delay at this input speed, and the frequent display and deletion causes significant eye fatigue. Furthermore, the contents of the primary code, which is repeatedly displayed and erased at such a high speed, cannot be recognized by the human eye.

Whether or not it is high-speed input is determined based on the number of primary codes stored in the input memory 3, that is,
If the second stroke "Ha" has already been input when the conversion processing unit 5 captures the first stroke "RO", the first stroke "RO" and "Ha" will not be displayed and the second stroke "Ha" will be inputted immediately. By moving to the process of converting the input into a secondary code and displaying only ``tada'', which is the content of the secondary code, an input device with excellent responsiveness and less strain on the eyes can be realized.

Next, as a second specific example, an example of an input method in which input is made in Roman letters and converted into kana will be explained with reference to FIG. According to the primary code string entered from the keyboard 1 as "k", "y", and "a" of the primary code 400, search the Roman dictionary, which is the code conversion table 6 in this case, and enter "kiya" of the secondary code 401.
is converted to Here, the conversion unit is usually "a" or "i"
This is until the vowels "u", "e", and "o" are input.
In a general Japanese word processor, this secondary code string converted into a kana character string is further converted into a third code string, a character string containing kanji and kana, through a kana-kanji conversion process, but regarding the technology of kana-kanji conversion, is already known, and only the technique for converting a primary code string into a secondary code string will be shown here.

As in the case of the two-stroke input method described above, in this specific example as well, by checking the value of the input counter 4 at the time when the conversion processing section 5 takes in the input code which is the primary code string from the input memory 3, By controlling whether or not to display the primary code, it is possible to realize an input device that has excellent responsiveness and does not put strain on the eyes.

Note that even for high-speed input users, when they feel an input error and want to check the input code, the input is interrupted and the input memory 3 no longer has the primary code waiting to be processed, and the input counter 4 becomes "0". The contents of the created primary code are displayed, so you can check them.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to control whether or not to display the input primary code string according to the input speed of the inputter, so inputters who are generally inexperienced with operations can You can input while checking the column contents. On the other hand, for experienced input users, the content of the secondary code, which is the conversion result, can be checked at high speed during high-speed input, so that an input device with very good responsiveness can be provided.
