Description

Description: TECHNICAL FIELD The present invention relates to a document processing apparatus having a function of automatically determining an input position after a confirmation operation of a homophone having a plurality of notations. [Prior Art] Conventionally, in a device for editing a character string, an indicator called a cursor is widely used as an index indicating a current operation position. In addition, the operation of inputting Chinese characters by performing so-called Kana-Kanji conversion is widely used, but for conversion candidates of multiple notations, the operator selects the notation candidate desired and confirms it in the document. Is needed. Since the cursor position is not changed in the confirmation operation, setting the cursor at the input position is left to the operator's instruction. [Problems to be Solved by the Invention] In the above-mentioned conventional example, since the confirming operation is only an operation of outputting a homophone expression as a confirmed character code in a document, intentionally changing the cursor position after the confirming operation. There was no. Therefore, if a confirmation operation is performed at a position other than the position where input is possible, the operator must instruct the operator to move the cursor to the position where input is possible, and the transition from the confirmation operation to the input operation cannot be performed smoothly. I couldn't edit the contents. An object of the present invention is to eliminate the drawbacks of the above conventional example. That is, the character processing device is realized, which follows the confirming operation, determines the position expected to be the next input position, moves the cursor, and shifts from the confirming operation to the input operation at high speed. [Means (and Action) for Solving Problems] In order to eliminate the problems included in the above-described conventional example, the present invention provides the following means to solve the problems and improve operability. A character processing device is provided. Therefore, the character processing device of the present invention displays a cursor display means for displaying a cursor indicating a new character input position on the display, a document storage means for storing a document, and a document stored by the document storage means. Document display means, a homophone display means for displaying an undetermined homophone in the document displayed by the document display means, and a homophone displayed by the homophone display means in response to a confirmation instruction. Symbol search means for storing a fixed notation in the document storage means and searching for a predetermined plurality of types of document control symbols from a portion following the fixed notation, and the predetermined plurality of types of document control by the symbol search means When any one of the symbols is searched for, the determining unit determines the next character input position based on the position and type of the detected document control symbol, and the determining unit. And a control means for controlling the cursor display means so that the separated character input position becomes the display position of the cursor. A predetermined plurality of types of document control symbols are searched from the subsequent portion, and when any one of the predetermined plurality of types of document control symbols is searched, the next document based on the position and type of the document control symbol. The input position is determined, and this character input position is used as the cursor display position.

In the figure, the cursor and the document displayed on the CRT screen are targeted. In (1), the letters with an underline are homophones, which means that a confirmation operation is necessary. When the enter key is pressed in (2), the cursor does not move as in (3) in the conventional example. Therefore, in order to continue input, the cursor is moved 9 times until (3) and (4). There must be. On the other hand, according to the present invention, by moving the cursor to the beginning of the next line maintained by the line feed mark as in (8), it is possible to continue and immediately input. FIG. 3 is a diagram showing the configuration of the document data buffer TBUF in the character processing device of the present invention. (1) is the overall structure of TBUF, and TXT (i) means a character code. (2) is a diagram showing a structure of a character code that is a homophone. The most significant byte of the homonym has a value of 1, and the remaining 15 bytes store the pointer to DOBF. (3) is a diagram showing a structure of a fixed character code. The value of the most significant byte of the definite character code is 0. The fixed character code is usually used Kana characters, English characters, numbers,
In addition to kanji, symbols, etc., a blank code that means an unentered code, a line feed code that instructs to move the characters after that code to the next line, and a page break code that instructs to move to the next page are used. FIG. 4 is a diagram showing the configuration of the selection candidate buffer DOBF. In the figure, CSWPTR is a pointer that describes the number of bytes from the beginning of the DOBF that the currently selected and displayed candidate character code is. CSWN indicates how many bytes the candidate character code currently selected and displayed consists of. WCOD
(I) means one code of the candidate character code string. FFFF is stored as an end code at the end of DOBF. If it is necessary to confirm in the document with the confirmation key, the DOBF head is obtained from the homophone pointer in the document code and the CSWN byte character code from the character code indicated by CSWPTR should be output in the document. become. FIG. 5 is a flow chart showing the operation of the character processing device of the present invention. In S5-1, a key is pressed from the keyboard KB and waits for an interrupt to occur.

Even if it has a matrix structure arranged in a dimension
Similar processing can be performed. [Explanation of Effect] As described above, according to the present invention, in response to a homophone word confirmation instruction, an unconfirmed homophone word is confirmed, and at the same time, a plurality of predetermined types of documents are written from the part following the definite notation. When a control symbol is searched and one of the predetermined plural types of document control symbols is retrieved, the next character input position is determined based on the position and type of the document control symbol, and this character input position is determined. Since the cursor display position is set to the cursor display position, if you try to enter a new document following the currently displayed document after the homophony is confirmed, the cursor position is set to the new input specified by various document control symbols. Since it is located at the position, there is an effect that the operator does not need to perform the operation of moving the cursor to a new input position.
Therefore, it is possible to provide a character processing device having high input operability.
