Description

Detailed Description of the Invention (a) Field of Industrial Application This invention relates to a word processor or a text processing device equipped with text processing *ti, and in particular to processing that cannot be processed in a text created by Ike's text processing device. The present invention relates to a text processing device that displays various control codes using specific symbols, and allows checking whether erasure is necessary when erasing the symbol.

(B) Conventional technology Conventionally, this type of text processing device has been used to edit and process text created by Ike's text processing device, and if there is a control code that cannot be processed in the text, the control code is The inserted part is displayed with spaces. In other words, in other text processing devices, for example, when enlarging a certain character or stopping printing at a desired position in a line, the control code inserted into the text is the symbol or character that corresponds to the control code. or the position of the control code is displayed as a space on a text processing device that cannot process the control code.

(c) Problem to be solved by the invention However, in the above configuration, the control code is displayed as a space, so when editing the displayed text, the existence of the control code is not known. There are inconveniences such as accidentally erasing the control code or not knowing where the control code you want to erase is located. In addition, when deleting the control code, you can easily delete it by moving the cursor to that position and pressing the one-character delete key, just like deleting a single character in a sentence. They tended to be easy to patrol.

This invention was made in consideration of the above circumstances, and in order to display an unprocessable control code with a specific symbol, and to erase the specific symbol, that is, the control code, after inquiring whether it is necessary or not. The present invention aims to provide a text processing device that can perform erasure processing as desired.

(2) Means for Solving the Problems Figure 1 is a block diagram that clearly shows the configuration of the text processing device of the present invention. In addition, a text storage means l for storing text data having various control codes, and a text storage means l.
a display means 2 for displaying a text corresponding to the text data stored in the display means 2; a determination means 3 for determining whether various control codes present in the text data of the text displayed on the display means 2 can be processed; The display control means 4 and the display means 2 display the control code determined to be unprocessable in accordance with 3 with a specific symbol at the position of the control code in the text displayed on the display means 2. a designation means 5 for designating a single character designated by the designation means 5; When one character is a specific symbol, an inquiry means 7 displays on the display means 2 information for inquiring whether erasure is necessary after an erasure instruction is inputted from the input stage 6; It is characterized by having an erasing means 8 for erasing a control code existing at a position corresponding to a specific symbol from the text storage means 1 in response to an instruction to execute erasure inputted from the input means 6 after the necessity is inquired. This is a text processing device.

As the text storage means in the present invention, for example, a floppy disk as a magnetic storage medium, its drive device, and a large capacity RAM, or a memory device containing a battery-backed RAM can be used. For example, text data stored on a floppy disk is input to the text storage device via the floppy disk.

The display means may use any display device known in the art, such as a CRT or LCD.

The determination means determines whether various control codes can be processed internally, and when developing the text data stored in the text storage means into image information, it compares the control codes with internally processable control codes one by one. By comparing the control code, it is determined whether the control code can be processed.

The determination means may be composed of, for example, a microprocessor, a ROM that stores a processable control code, a ROM that stores a program for checking, or the like.

Control codes include equal allocation, printing stop, enlarged printing,
The code is for text editing such as color printing, and may include external character codes other than JIS codes.

The display control means displays a specific symbol at a certain position of the control code when there is a control code that is determined to be processable. This can be done with a display buffer that stores the . The specific symbol may be a specific character set in advance.

Since the designation means determines one of the characters including the above-mentioned specific symbol on the screen of the display means, the designation may be performed using, for example, a cursor. The cursor may be configured so that it can be moved using a cursor movement key (cursor key) on a keyboard or a pointing device such as a mouse.

As the input means, a keyboard having kana/alphabetic keys, sanji keys, various types of funkyon keys, etc. is preferable. Alternatively, it may be composed of a keyboard and a pointing device such as a mouse. The funky keys include a character delete key, an execution key, and a release key.

The inquiry means is configured to cause the display means to display information for inquiring whether erasure is necessary or not, when a specific symbol is designated by the designation means and an instruction to delete the particular symbol is input. be decapitated. The inquiring means may be composed of, for example, a ROM that stores information for inquiring whether or not the portrait is necessary, a microprocessor, or the like.

When the object to be erased is a specific symbol, the erasing means textualizes the control code existing at the position corresponding to the specific symbol in response to an instruction to execute erasing that is input after the above inquiry information is displayed. It is configured to erase from li2 billion means.

It should be noted that the microprocessors used to constitute the above-mentioned determining means, display control means, inquiry means and erasing means may be the same, and may be 8-bit, 16-bit or 32-bit microprocessors.

(E) The action display means displays a sentence corresponding to the sentence data stored in the sentence storage means. The display control means indicates the position of the control code in the text using a specific symbol for the control code that the determination means has determined cannot be processed among the various control codes existing in the text data of the text displayed on the display means. to be displayed.

When the displayed specific symbol is designated by the designation means and an instruction to delete one character is input from the input means, the inquiry means causes the display means to display information for inquiring whether deletion is necessary.

After that, an instruction to execute the deletion is input from the input means.
The erasing means erases the control code located at the position corresponding to the specific symbol designated by the designation means from the text storage means.

Therefore, it is possible to prevent unprocessable control codes from being inadvertently erased.

(f) Examples Examples of the present invention will be described below in detail with reference to the drawings, but the invention is not limited to the following examples.

In FIG. 2, {l is a keyboard as a specifying means and an input means, and l2 is a CRT as a display means. The keyboard 1l has character keys, numeric keys, cursor keys, execution key, release key, character deletion key, and is connected to the control panel 13.

The controller 13 consists of a microcomputer, an I/O interface, a character generator, etc., and according to the control program stored in the main memory 14,
Performs various processes described below. In the main memory l4, information is stored in a predetermined area for inquiring whether or not erasing a specific symbol, which will be described later, is necessary. In addition to character patterns (image information) corresponding to normal characters, the character generator should have image information for specific symbols to be displayed in place of unprocessable control codes. A display buffer l5 for storing image information to be displayed is connected to the control unit 13, and the control unit l3 converts the text data stored in the text memory l6 into the display buffer l5 into image information. Expand and memorize. The image information stored in the display buffer l5 is transferred to a CRT controller (CRTC) 17.
is displayed on the CRT 12.

The text memory l6 is a floppy disk device using a floppy disk as a storage medium, and text data is stored on the floppy disk. The text data stored on the floppy disk may be created by another text processing device, or may be text created and stored by the device. The text data taken out from the floppy disk is stored in the auxiliary text memory l8 via the control section 13.

The Urasuke text memory 18 is also used to store text data of a text created by the device until it is stored (text registered) in the text memory 16, and is constituted by a RAM.

Next, the operation of this embodiment will be explained with reference to FIGS. 3 to 5.

When the power is turned on, the keyboard IL display buffer l5
and Urasuke Sentence Memory! 8 is initialized, and a key input from the keyboard 1l is awaited.

Here, a floppy disk that stores text data having various control codes created by another text processing device is placed in the text memory l6, and the text data is taken out and stored in the Urasuke text memory 18. shall be taken as a thing.

FIG. 3 is a flowchart showing a process for displaying text data stored in the auxiliary text memory l8 on the CRT l2.

First, control l3 displays l from auxiliary text memory l8.
Characters are extracted (step 100). The next l taken out
It is determined whether the character code is a control code (step l01). As a result, if it is a character code rather than a control code, the image information corresponding to the character code of the character generator is stored in the display buffer l5, and CR
It is displayed on the CRT 12 via the TCl 7 (step 102).

If it is determined in step 101 that it is a control code,
It is determined whether the control code is a control code that can be processed internally (step +03).

If the control code is an unprocessable control code,
Image information of a specific symbol of the character generator is stored in the display buffer l5 and displayed on the CRT 12 via the CRTC l7 (step l04). The specific symbol 20 is displayed as "toku" as shown in FIG. 5, and is displayed as an outline character so as to be easily distinguished from the character for pond.

If it is determined in step 103 that the control code can be processed, image information corresponding to the control code is extracted from the character generator, stored in the display buffer 15, and displayed on the CRT 12 via the CRTCl 7. (Step 105), above steps 100~
Step 105 is performed on all the character data and control codes of the text data in the auxiliary text memory 18, and the text corresponding to the text data is displayed on the CRT12.

Next, a description will be given of a process when one character is deleted while a sentence is being displayed as described above.

FIG. 4 is a flowchart of the process of erasing one character.

First, the user presses the cursor key on the keyboard 1l and specifies the character to be erased using the cursor 2l (see FIG. 5). When the one-character delete key on the keyboard 2 is pressed, the control unit l3 retrieves the character specified by the cursor 2l, that is, the character code at the cursor position, from the auxiliary text memory l8 (step 200). Next, it is determined whether the extracted character code is a control code (step 20I).
).

If it is not a control code, the character specified by the cursor 2l is erased from the display buffer l7 and the auxiliary text memory l8 (step 202), and the text excluding the erased character is displayed on the screen (step 203).

If it is determined in step 201 that the extracted character code is a control code, it is determined whether the control code can be processed internally (step 204). If the control code is processable, the erasure process is different for each control code, so the control code is erased by the process set for each control code. Conversely, step 204
If it is determined that the control code is an unprocessable control code, that is, if it is a specific symbol code, an inquiry message, which is information inquiring whether erasure is necessary or not, is sent to C.
Display a window on RT l 2 (step 206)
. After confirming this inquiry message, the user inputs a key (step 207), and it is determined whether the key input is an execution key (step 208). If it is an execution key, the control code, that is, the specific symbol on the screen, is erased in step 202, and the control code is erased in the Urasuke text memory 18, and step 203 is executed. If the key input is not an execution key, it is determined whether it is a release key (step 209), and if it is a release key, the one-character deletion process is canceled. If it is not a release key, the input is an invalid key, so the process returns to step 207 to wait for the key input, and when the key input is made, step 208 is executed again.

(g) Effect of the invention According to this invention, a control code that cannot be processed internally is displayed with a specific symbol, and when the specific symbol, that is, the control code, is to be erased, an inquiry message is displayed. Therefore, it is possible to obtain a document processing device in which the control code is prevented from being deleted by mistake, and editing and proofreading operations are improved.
