Abstract

PURPOSE:To improve the operability by including a mode changeover code in a registered character string so as to attain automatic changeover of the input mode when a registered character string is called thereby eliminating the need for the mode changeover operation by the operator. CONSTITUTION:When a character string 'Sea is wide (Umiwa hiroina)' and the mode changeover code in English capital letters are registered in the reading of 'sea (Umi)', and when a mode storage section 3 gives a Hiragana (round form of Japanese syllabary) mode, the reading 'Sea (Umi)' is inputted and the conversion key is depressed, then a character string converting section 7 is started. The section 7 retrieves a conversion dictionary 6 based on the reading of 'Sea (Umi)' to call the character string of 'Sea is wide' register before and the English capital letter mode changeover code. The character string 'Sea is wide' is set again in an input buffer 5 and displayed on a display device 12 by a display control section 11. On the other hand, the English capital letter mode changeover code is extracted from the registered character string to a detection section 8 and the mode changeover section 9 changes the storage content of the mode storage section 3 into the English capital mode.

Description

[Detailed Description of the Invention] [Summary] For example, in a document creation device, etc., a mode switching code related to an input mode can be registered in advance together with a registered character string in so-called word registration or sentence registration, and this registered character string can be called. The present invention discloses a device that improves operability by automatically switching the keyboard input mode to various specified modes such as hiragana mode, katakana mode, uppercase alphabet mode, and lowercase alphabet mode.

[Conventional technology]

Keyboards are often used as input devices for electronic computers. Generally, there is a limit to the number of keys that can be provided on a keyboard, so the number of keys can be increased by using a so-called shift key, and different character codes can be entered for the same key depending on the input mode. things are being done.

In addition, 1. For example, in a document creation device that creates Japanese documents, it is possible to input the ``yomi'' and convert it to kanji, or to convert a character string containing a pre-registered word to the ``yomi'' specified at the time of registration. ” and replaces the “yomi” with the original registered character string.

[Problem that the invention seeks to solve]

By the way, in conventional document creation devices, etc.

When calling a registered character string, the input mode before the call and the input mode after the call remain unchanged. That is, 9, for example, in hiragana mode, input the reading and call up a certain registered character string. Then, the reading will be converted to the registered character string, but the input mode is Hiragana mode, so if you want to change to English capital letter mode after calling up the registered character string, be sure to press the "English capital letter" key from the keyboard. Therefore, it was necessary to convert to upper case mode.

The present inventors also provided intelligence to a keyboard, which is an input device for a computer.

I am thinking of developing a device that converts kanji and character strings on the keyboard without involving the host computer, but in this case, I would like to register the commands to be input to the host computer in 9, for example, Japanese readings. If possible, it would be convenient in terms of operability, and if the mode could be switched automatically and freely in advance using registered character strings, operations such as when switching between Japanese input and command input would be simplified. , it is thought that erroneous operations can be prevented.

[Means for solving problems]

The present invention aims to solve the above-mentioned problems and provides means for automatically switching the input mode when a registered character string is called up in a document creation device or the like. To explain according to the embodiment shown in FIG. 1, the input mode automatic switching processing method of the present invention includes a mode storage unit 3 that stores input modes;
A conversion dictionary 6 that stores a designated character string in accordance with a designated reading, and character string registration that registers the designated mode switching code in the conversion dictionary 6 together with the character string registered in the conversion dictionary 6. a switching code detection unit 8 that detects the mode switching code in the character string when the character string registered in the conversion dictionary 6 is called according to the reading inputted from the keyboard 1; The mode storage unit 3 is updated according to instructions from the code detection unit 8,
It is provided with a mode switching section 9 for switching the input mode, and is configured so that the input mode can be automatically switched by calling a registered character string.

[Effect]

According to the present invention, mode switching codes associated with various input modes such as hiragana mode, katakana mode, English uppercase mode, and English lowercase mode can be registered in the conversion dictionary in the same way as with ordinary characters. It has become. Then, when the registered character string is called and a mode switching code is detected, the keyboard input mode is changed.

Automatically converts to the mode of the detected mode switching code. Therefore, for example, after calling up a predetermined registered character string such as a command, it is possible to set the desired input mode.

〔Example〕

FIG. 1 is a block diagram of an embodiment of the present invention, FIG. 2 is a diagram for explaining input modes according to the present invention, FIG. 3 is a diagram for explaining automatic mode switching according to the present invention, and FIG. 4 is a diagram for explaining automatic mode switching according to the present invention. An example of application of the present invention will be shown.

The keyboard 1 is a device that includes key switches and inputs characters including control characters by pressing keys. The keyboard control section 2 is a circuit that controls the keyboard 1.

The mode storage unit 3 is a circuit that stores current input modes such as hiragana mode, katakana mode, uppercase alphabet mode, and lowercase alphabet mode.

The code conversion section 4 performs a process of converting input data from the keyboard control section 2 into a predetermined character code corresponding to the mode according to the mode stored in the mode storage section 3. The converted character code is stored in the input buffer 5.

The conversion dictionary 6 is a device that stores registered character strings such as words and sentences containing kanji in correspondence with specified pronunciations.In the case of the present invention, a part of the registered character strings includes a predetermined mode switching code. It is now possible to

The character string converter 7 searches the conversion dictionary 6 based on the input pronunciation by inputting a conversion key, for example, and performs a process of calling up a registered character string. A code detection section 8 is provided.

The switching code detection unit 8 detects that in the called registered character string,
It is checked whether a predetermined mode switching code is included, and if the mode switching code is included, the mode switching unit 9 is activated.

The mode switching unit 9 updates the contents of the mode storage unit 3 according to the notified mode switching code.

This executes the process of switching the current mode. The mode switching section 9 also executes processing for updating the mode storage section 3 using alphabetic keys, katakana keys, etc. notified from the keyboard control section 2.

The character string registration unit 10 executes a process of registering a designated character string in the conversion dictionary 6 in response to a registration instruction from the keyboard control unit 2 in correspondence with the reading.

The display control unit 11 includes a one-screen buffer (not shown),
Of course, when a registered character string is called by the single character string converter 7, which controls the display of the input data set in the input buffer 5, it also controls the display of the registered character string. The display 12 is a character display device such as a CRT or liquid crystal display.

FIG. 2 is a diagram illustrating designation of an input mode when registering a mode switching code.

In this embodiment, the input mode is hiragana mode.

4 modes: katakana mode, upper case mode, lower case mode
There are different types. For example, when registering a mode switching code to switch to Hiragana mode.

A hiragana mode code is included in the character string to be registered by manually pressing the ALT key and the numeric key "1". Similarly, when it is desired to automatically switch to the katakana mode, as shown in FIG. 2(b), by pressing the ALT key and the number key "2", the registration of the katakana mode code is designated. The same applies to (C) uppercase alphabet mode and (d) lowercase alphabet mode. Display 12 corresponds to the above key manual during registration.

Mode switching codes such as D to D4 are displayed respectively.

In the case of a keyboard for a document creation device, for example, instead of the ALT key, various control keys such as a "semi-voiced sound" key can be used. In addition, a dedicated key for mode switching may be provided.

Next, an example of automatic mode switching will be explained according to FIG. For example, as shown in FIG. 3(a), the character string ``The sea is wide'' and the mode switching code in uppercase English letters are changed to ``The sea is wide.''
Let's say you registered it with the reading ``Umi''. Note that this registration is performed by the illustrated character string registration unit 10 in FIG. 1, but regarding this registration process.

This process can be considered to be similar to the process known in conventional document creation devices, except that a mode switching code can be registered.

For example, as shown in FIG. 3(b), when the illustrated mode storage section 3 in FIG. 1 indicates the hiragana mode.

Assume that the reading "Umi" is input and the conversion key is pressed. As a result, the 9 character string converter 7 is activated. The character string conversion unit 7 searches the conversion dictionary 6 based on the pronunciation of ``sea'' and calls up the previously registered character string ``The sea is wide'' and the English capital letter mode switching code. "
The character string "The sea is wide" is reset in the input buffer 5 and displayed on the display 12 by the 2-display control section 11.

On the other hand, the English capital letter mode switching 5 code is detected by the switching code detection section 8, extracted from the registered character string, and transmitted to the mode switching section 9.

The mode switching section 9 thereby changes the storage contents of the mode storage section 3 to the uppercase alphabet mode. From then on.

The data input from the keyboard 1 is sent to the code converter 4.
is converted to a character code in the uppercase alphabet encoding system. That is, the hiragana mode is automatically converted to the uppercase alphabet mode.

FIG. 4 shows an example of application of the present invention. For example, the present invention is not limited to a dedicated document creation device, but also to normal data processing by the host computer 20.

It is desired to be able to easily input Japanese character strings.

In general, conversion into Japanese characters is processed in the host computer 20 according to input from the keyboard.
4 is normal, but this results in an increase in the amount of data communication and an increase in the processing load on the host computer 20. Therefore, a so-called intelligent keyboard 21 is being considered that can perform some Japanese processing such as kana-kanji conversion and character string registration within the keyboard rather than within the host computer 2o.

For example, when receiving a conversation processing service provided by the host computer 20, the LOG requesting the start of a session is
Although it is necessary to input an ON command, it is also necessary to input user identification information and other information as parameters for this command. In this case, inputting commands can be simplified by using the character string registration function of the intelligent keyboard 21. That is, 1, for example, a string of characters of a series of LOGON commands is registered as "Asa". Then, just by inputting "Asa" and pressing the conversion key etc., the log will be sent to the host computer 20.
Now you can send the ON command character string.

After that, in order to input the first conversation command, it is generally necessary to convert the input mode to upper case mode, etc.5 In the case of the present invention, in the registered character string with the reading ``Asa'', as shown in Figure 2. This mode switching process can be automated by entering the mode switching code in uppercase letters as explained in Section 1 above. Therefore, the operation becomes simple and erroneous input due to mode errors is prevented.

In addition, in FIG. 4, numerals 3.7 correspond to those in FIG. 1, 22 specifically indicates the key switch part of the keyboard, and 23
represents a control circuit including a microprogram stored in a ROM or the like.

〔Effect of the invention〕

As explained above, according to the present invention, by including a mode switching code in a registered character string, the input mode can be automatically switched when the registered character string is called, and the operator can.

Since there is no need to press a mode changeover switch or a mode changeover key, operability is improved. Also.

Input errors caused by forgetting to switch modes are reduced.
