Abstract

PURPOSE:To improve inputting operability, by displaying a message, etc., without erasing a document displaying at present, when a required message, etc., is displayed on a display screen on which the document of a prescribed display line is displayed. CONSTITUTION:A CPU not shown in figure executes the shift process of a character string of designated range, and gives the instruction of a display operation to a liquid crystal display (LCD) control device 20. At such a time, since the bit of request information of a message register 28 is reset, a bit of L level information which designates a three line display mode is set at a display mode register 24. Therefore, the device 20 displays the document after the shift process in a three line display on a screen corresponding to a bit of information in the register 24. Thus, when the document is displayed in the three line mode, and a request to display the message required for a correction/editing process in a correction/editing mode, is generated, a required message is displayed at the fourth line on the screen without erasing the document of three lines displayed in a documentation time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention particularly relates to a simple document creation device having a display screen of several lines.

(Prior Art) In recent years, simple document creation devices have been developed that have a limited display screen of only a few lines. In such a document creation device, for example, three lines of character strings of a created document are displayed on a three-line display screen. By the way, the document creation device performs proofreading/l! such as moving, copying, and deleting character strings of a created document into an arbitrary document. Toki Togane is functioning. When executing such a proofreading/I collection function, a message necessary for the execution may be displayed.

However, in the above-mentioned document creation apparatus, since the number of display lines on the display screen is limited, it is necessary to erase a part of the currently displayed screen in order to display a message. That is, for example, one of the character lines on the display screen (usually the last displayed line) is erased, and a message is displayed in place of the erased character line.

(Problem to be Solved by the Invention) In the above-mentioned simple document creation device, when executing the proofreading/IF collection function, it is necessary to erase a part of the document on the screen in order to display the message. was there. For this reason, since the erased part cannot be confirmed on the screen, there is a problem that input operability deteriorates.

An object of the present invention is to display messages, etc. necessary for proofreading/editing functions on a display screen where a document in a predetermined display line is displayed, without erasing the currently displayed document. An object of the present invention is to provide a document creation device that can display images and improve input operability.

[Structure of the invention] (Means and effects for solving the problem) The present invention has a display function using a plurality of display modes with different display lines,
It has a configuration that when displaying a message, etc. necessary for proofreading/editing functions on a screen displaying a document in a predetermined display mode, the display mode is changed to display the current document, message, etc. .

That is, the present invention includes display mode storage means for storing display mode instruction information when displaying a document on a display screen, and control information storage means for storing control information such as messages other than documents. Furthermore, when the document is displayed in the display mode according to the instruction information of the display mode storage means,
When a request to display the control information occurs, the display mode changing means changes the display mode to the number of display lines necessary for displaying the document and the control information, and the document and the control information are displayed in the display mode changed by the display mode changing means. It is equipped with display means for displaying on a display screen.

(Example) The present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing the basic configuration of a document creation device according to an embodiment. In Figure 1, a microprocessor (C
PIJ) 10 is a circuit that performs document creation processing, proofreading/editing processing, display control processing, and control operations for the entire apparatus.

The RAM 11 is a read/write memory used as a document memory for document creation (text buffer 7 memory), a new word registration dictionary memory, and the like. ROM12 is CPU
This is a read-only memory in which programs that determine the operations of 10, message tables and standard dictionaries necessary for proofreading/I collection processing are stored in advance. The liquid crystal display device (LCD device) 13 has a display screen that can display up to four lines, for example, and is equipped with an LCD III ill device that changes the display lines according to the display mode specified by CP tJ 1G. . The keyboard 14 is used for document creation processing and proofreading/
This is an input device equipped with various input keys necessary for editing processing, etc.

FIG. 2 is a block diagram showing the specific configuration of the same embodiment. In Figure 2, an LCD (liquid crystal display) 21
and L CD Ill tlD device 20 is the LC of FIG.
This device constitutes the D device 13. The message table 22 is made up of message data necessary for proofreading/S collection processing, and is stored in the ROM 12 in advance. The text buffer memory 23 is a document memory area provided in the RAM 11. The display mode registers 24 and 27 are registers that store instruction information for instructing either the 3-line display mode or the 4-line display mode. The message register 28 is a register that stores request information when requesting the output of a message necessary during proofreading/editing processing.

Next, the operation of this embodiment will be explained. First, in this embodiment, the LCD 21 has a display screen that can display a maximum of four lines (four-line display mode), as shown in FIG. In the normal document creation mode, the L:CD control device 20 controls the display screen of the LCD 21 to display character strings in a three-line display mode, as shown in FIG. In the document creation mode, the CPU 1G creates a document based on input information input from the keyboard 14, and develops the document into the text buffer memory 23. At this time, the CPU 10 outputs 3-line display mode instruction information (“L” level information) to the display mode register 27.

The instruction information of the display mode register 27 is transmitted to the inverter 26
After being inverted by , the signal is output to one input terminal of the NAND circuit 25 . The NAND circuit 25 outputs the request information stored in the message register 28 to the other input terminal. In this case, the message register 28 is
Request information from No. 10 (“L” level is active information) is not output, but rHJ level information is stored. Therefore, rLJ level information is output from the NAND circuit 25 to the display mode register 24. Then, the CD control device 20 determines that it is the 3-line display mode using the rLJ level information in the display mode register 24 (11!). Then, the document developed in the text buffer memory 23 is controlled to be displayed on the screen of the LCD 21 in a three-line display mode.

As a result, as shown in FIG. 5, a three-line document is displayed on the screen of the LCD 21.

Now, suppose that a request for proofreading/editing, such as moving part of a character string to another character string, is generated for a created document. When such a request for proofreading/It collection processing is input from the keyboard 14, the cpu io
changes from document creation mode to proofreading/m collection mode. Specifically, it is assumed that, for example, the "movement function key" on the keyboard 14 is operated and the cursor 30 is further moved to the starting position of the character string to be moved, as shown in FIG. C.P.
The U 10 performs a process of displaying a message in order to specify the range from the start position of the character string to be moved as the next process necessary for the "movement function". Message data necessary for proofreading/editing processing is stored in advance in a message table 22 of the ROM 12.

The CPU 10 performs control such as outputting a message number determined in advance for each data, reading necessary message data corresponding to the message number from the message table 22, and outputting it to the LCD Ill ill device 20.

At this time, the CP tJ 10 outputs request information ("SHI" level information) for requesting message output to the message register 28. In response to the request information from the message register 28, necessary message data is output from the message table 22 to the LCD control device 20. Further, the request information is output to one input terminal of the NAND circuit 25. As a result, even if the display mode register 27 stores rLJ level information, the display mode register 24 stores rHJ level information. L
The CD control device 20 controls rHJ of the display mode register 24.
The screen of the LCD 21 is changed from 3-line display to 4-line display according to the level information. In this 4-line display mode, the LCD control ll@device 0 displays the message output from the message table 22 (up to a point?) as shown in FIG.
) is displayed on the LCD 21 screen.

Depending on the message displayed on the LCD 21 screen,
Input operations necessary for the "movement function" are performed using the keyboard 14. That is, for example, the character string shown in Figure 6 is "Kiku".
Suppose that you specify the range up to and the destination is specified next to ``Sashi'' on the 33rd line. As a result, the CPU 10 executes the process of moving the character string in the specified range, and
A display operation instruction is given to the ill device 20. At this time, since the request information in the message register 28 is reset, rLJ level information instructing the 3-line display mode is set in the display mode register 24. For this reason, L
As shown in FIG.
It is displayed on the LCD 21 screen in line display.

In this way, when a document is displayed in 3-line display mode, if a request to display a message necessary for proofreading/wA collection processing occurs in proofreading/If collection mode, the display screen will be changed to 3 lines.
It is possible to change from line display to four line display. Therefore, a necessary message can be displayed on the fourth line of the screen without deleting the three lines of the document displayed when the document was created.

In the above embodiment, if the 4-line display mode instruction information is output from the CP Ll 10 to the display mode register 27, regardless of whether or not there is a message output request,
The LCD control device 20 always performs display in the 4-line display mode.

[Effects of the Invention] As detailed above, according to the present invention, in a document creation device with a limited display screen, by being able to select and specify a plurality of display modes with different numbers of display lines, the currently displayed document can be changed. Messages, etc. necessary for proofreading/editing functions can be displayed without erasing the information. Therefore, in the proofreading/editing mode, you can check the message and the document displayed during document creation on the screen and proofread/I! Since input operations necessary for collection processing can be performed, input operability can be improved as a result.
