Description

Description: TECHNICAL FIELD The present invention relates to a character string input device, and more particularly to a character string input device such as a word processor used by a user in combination with various character types and modes. .

[Conventional technology]

In a character string input device such as a word processor,
The character type is specified by operating the keys on the keyboard.

Conventionally, a selection key for a character type (for example, hiragana, alphanumeric characters, etc.) and a selection key for a character mode (for example, full-width, half-width, etc.) act independently of each other, and after the use in the type A, the mode a, the type B, When used in mode b, the mode remains b even if the type is returned to A again, and it was necessary to set the mode to a again for use in the previous state. Regarding the character type setting function, see, for example, Seabold, Jyonathan “Zero-Tux'Star ',” The Seabold Report, Media,
Pennsylvania: Siebold Publications,
Volume 10, Issue 16, 1981 (Seybold, Jonathan. “Xerox's'Sta
r ', "In The Seybold Report, Media, PA: Seybold Publica
tions, vol.10, no.16, 1981.), there is a method of switching the type of characters that can be used as a virtual keyboard, but this specifies the font set itself, and the character type and character mode. It lacks the flexibility to specify separately.

[Problems to be solved by the invention]

The above-mentioned prior art uses a combination of various character types and character forms, as can be seen remarkably in Japanese word processors, and when those changes are frequent, the document itself is changed by a character type change operation. No consideration has been given to the fact that thinking is disturbed, and when this operation is performed a large number of times, there is a problem that the user is tired. An object of the present invention is to facilitate the setting of the character type or character mode in the above-mentioned character string input device and reduce the labor of the user.

[Means for solving problems]

In order to achieve the above object, the present invention selects a plurality of character keys, first means for designating the type of character input by the character key, and a mode of character input by the character key. Therefore, in the character string input device provided with the second means, the third means for storing the correspondence between the character type and the character form as a fixed relation is provided, and when the character type is designated, the third means is stored. It is characterized in that the input characters are processed in the character form stored as the fixed relation unless the character form is temporarily specified.

[Action]

In the present invention, when the user newly specifies the character type or suggests the use of the fixed relation after the processing in the temporary character form, the character type is already stored (registered). The character string is processed by the fixed relation. When the user temporarily specifies a different mode, the mode is stored as a temporary association, and the character string is processed based on that. The user can change or newly add a fixed relation. In this case, the designated fixed relation is set as the temporary relation, and the character string is processed based on the temporary relation.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the appearance of a word processor to which the present invention is applied. As shown, the word processor is a CRT
It consists of a display unit 101 and a keyboard 102.
2 is provided with various character keys 103, a character type setting key 104, a character mode setting key 105, and a fixed related setting key 106, and each of 103, 104, and 105 is composed of a plurality of keys. The character type setting key 104 includes, for example, hiragana, katakana,
Keys such as alphanumeric characters are provided, and as the character mode setting key 105, full-width, half-width, double-width, quadruple-width, etc. keys are provided.

The character key 103 is a normal key for generating a character string in a document. When one of the character type setting keys 104 is pressed, the character type corresponding to the key is selected, and at the same time, the character mode indicated by the fixed relation stored in advance corresponding to the character type is selected. When one of the character mode setting keys 105 is pressed, the character type used at that time is retained as it is, and the character mode corresponding to the pressed key is selected. When only the fixed relation setting key 106 is pressed and released, the character type used at that time is retained as it is, and the character form indicated by the fixed relation stored in advance corresponding to the character type is selected. . When one of the fixed relation setting key 106 and the character form setting key 105 is pressed at the same time, the form indicated by the character form setting key is stored as a fixed relation corresponding to the character type used at that time, and at the same time, , The aspect is also stored and used as a temporary association.

The key operation for actually creating a character string will be described by taking the character string shown in FIG. 2 as an example. Reference numerals 201, 202, 203, and 204 denote character forms, where 201 is a double-width character, 202 is a double-width character, 203 is a double-width character, and 204 is a half-width character. By default, double-width characters for Kana-to-Kanji conversion and non-converted Hiragana characters, and double-width characters for alphanumeric characters are registered as fixed relations, and the current character types are Hiragana and Temporary. Assume that the association is double angle. The user first creates a character string “line segment”, then uses one of the character type setting keys 104 to change the type of character to alphanumeric and inputs the character string “AB”. Next, one of the character type setting keys 104 is used to change the used character type to hiragana, a character string “to” is created, and one of the character mode setting keys 105 is used to set the temporary relation to quadruple. To create the string "arbitrary". Next, the fixed relation setting key 106 is pressed to return the temporary relation to the horizontal role, the character string “line segment” is created, and one of the character type setting keys 104 is used to set the character type to alphanumeric. To create a character string “X”. Furthermore, one of the character mode setting keys 105 is used to set the temporary relation to half-width, create the character string “ab”, and create the “intersection point” by the same operation as the above “line segment”. rear,
Using one of the character type setting keys 104, the type of character used is set to alphanumeric and a character string "P" is created.

FIG. 3 is a block diagram of a device for realizing the present invention. In this embodiment, there are n character types and m character forms, and the codes expressing each are 1, ..., N for the character type and 1, ..., M for the form. In such a configuration, when each key is pressed on the keyboard 102, the keyboard driver 303 causes
A code according to the state of the pressed key is generated and stored in the register 304. The CPU (central processing unit) 308 executes the processing indicated by the program stored in the storage device 305 according to the code stored in the register 304. CRT
The characters to be displayed on the display unit 101 are written in the frame buffer 309 as a code by the CPU 308. On the other hand, the screen display adapter 310 reads the code stored in the frame buffer 309 and displays the corresponding character image on the CRT display unit 101 using the CG memory 311. When the user inputs a character string by using the character keys 103 on the keyboard 102, the original character string data is stored in the storage device 306, and after the processing such as kana-kanji conversion is performed, the confirmed character string data is stored in the storage device. It is stored in 307. The original character string data is created character by character. In this case, the register 312 indicates the type of character to be created, and the register 313 indicates the mode of character to be created. That is, the register 312 stores a code representing the currently selected character type, and similarly, the register 313 stores a code representing the currently selected character mode. Each of the registers 314 to 313 + n has n
A fixed association corresponding to each character type is stored, and the character type represented by the code i is assigned the register 313 + i. The contents of the registers 312, 313, 314 to 313 + n are the character type setting keys 104 on the keyboard 102,
It is controlled by a program process that is read from the storage device 305 and executed corresponding to the code stored in the register 304 by pressing the character mode setting key 105 or the fixed related setting key 106. The details of the above-mentioned program processing will be described below with reference to the flowchart.

FIG. 4 shows the code stored in the register 304.
9 is a flowchart showing how different processes are executed thereafter.
First, the register 3 is selected by the input operation from the keyboard 102.
Monitor whether code is stored in 04 (step 40)
1). When a keyboard input occurs, if the input code indicates that only the character type setting key 104 has been pressed (step 402), the code representing the character type indicated by the pressed key is stored in the register 312, and the step Proceed to 407 (step 403). If the input code indicates that only the character mode setting key 105 has been pressed (step 4
04), the code representing the character form indicated by the pressed key is stored in the register 313 (step 405). If the input code indicates that only the fixed related setting key 106 is pressed (step 406), the register (313+ (register 312
Content)) is stored in the register 313 (step 4).
07). If the input code indicates that the fixed relation setting key 106 and the character mode setting key 105 are pressed at the same time (step 408), the code representing the character mode indicated by the pressed key is registered in the register 313 and the register (313+ ( Register 31
2)))) (step 409), and if the input code does not match any of the above, other processing is executed (step 410). If all processing has not been completed (step 411), the process returns to step 401, and the input from the keyboard is again received.

〔The invention's effect〕

As is clear from the above description, according to the present invention, the convenience and the character form are automatically selected for the user for each character type. In addition, since the character form used temporarily can be changed to return to the main character form at any time, the character form can be changed for users who frequently switch between various character types and character forms. It is not necessary to reset frequently and the input operation can be greatly simplified.
