Description

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

(Prior Art) In recent years, a simple document creation device U having a display screen limited to a few lines has been developed. In such a document creation device, for example, four lines of character strings of a created document are displayed on a four-line display screen. By the way, the document creation device includes a proofreading/editing function for moving, copying, or deleting a character string of a created document into an arbitrary document. When executing such a proofreading/m collection function, it may be necessary to specify a range of character strings to be proofread/edited with a cursor.

In such a case, in order to specifically display the designated range on the display screen, there is a method of displaying the character string in the range designated by the cursor in reverse video. In such a system, after setting a designated range with the cursor, for example, when the cursor is moved to the destination of the character string and the display screen is scrolled, the inverted display of the character string in the designated range is canceled. However, in the above-described method, after scrolling the display screen, there may be a case where it is desired to check the character string in the designated range again, but it is difficult to do so because the inverted display has been canceled.

(Problem to be Solved by the Invention) In the conventional method described above, character strings are displayed in a specified range in proofreading/wA collections, etc., but this is canceled after scrolling, so the character strings in the specified range are displayed again. It was inconvenient to check.

An object of the present invention is to enable the character strings in the specified range to be displayed in reverse video again even if the display screen scrolls after the character strings in the specified range are highlighted with the cursor. An object of the present invention is to provide a document creation device that can improve input operability with confirmation.

[Structure of the Invention] (Means and Effects for Solving Problems) The present invention memorizes the inverted display range of a specified character string, and when the display screen is scrolled after the character string is inverted, the character string is displayed again. The document creation device is configured to automatically reverse display columns when displaying them.

That is, the present invention provides a reverse display designation means, a reverse display means, a detection means for detecting a change in the display screen, and a determination unit for determining whether character string data in the reverse specified range is included in the display range when the display screen changes. and a means for reversing the display. The reverse display specifying means designates and stores a range of character string data to be displayed in reverse among the specified range of character string data according to display control information set in advance. The detection means detects whether or not a display screen of character string data in a specified range including the character string data displayed in reverse by the reverse display means has changed due to scrolling.

The determining means determines whether, when the detection result of the detecting means is that the display screen has changed, the character string data in the inverted specified range specified by the inverted display specifying means is included in the specified range corresponding to the display screen. Determine whether or not it is possible. The re-inversion display means is configured to display the character string data in the inversion designated range again in inversion based on the determination result of the determination means.

(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
The PU) 10 is a circuit that controls the entire apparatus, and executes text creation processing, proofreading/editing processing, and display νJilt processing. RAM 11 is a document buffer fJi area,
Display flag area and reverse display! It is a read/write memory that has till ill tables and the like. ROM12
is a read-only memory that stores in advance a program that determines the operation of the CPU 10, a calibration/I collection, a message table necessary for processing, a standard dictionary, and the like. The keyboard 13 is an input device equipped with various input keys necessary for document creation processing, proofreading/II collection processing, and the like. The keyboard controller 14 is a control circuit that constitutes an interface between the CPU 10 and the keyboard 13. Display 1
Reference numeral 5 is a liquid crystal display device (LCD device), and has a display screen capable of displaying, for example, four lines at maximum. The display controller 16 is an LCD control device that changes the display screen of the display 15 using the CPU 10 and the ill 10. FDC 17 and FDC 18 constitute a floppy disk device for storing created documents. The printer 19 and printer controller 20 constitute a printing device for printing the created document.

Next, the operation of this embodiment will be explained. In this embodiment, the display device 15 includes a display screen that can display up to four lines, for example. In the document creation mode, the CP LJ 10 creates a document based on input information input from the keyboard 13, and develops the document into the document buffer area of the RAM 11. CPU IO performs control to display the document developed in the document buffer on the display screen of the display device 15. At this time, the CP LJ 10 sets various flag information necessary for the display operation in a display flag area 30 provided in advance in the RAM 11, as shown in FIG.

The display controller 16 displays the document data and cursor output from the CPU 10 on the screen of the display 15 based on the flag information in the display flag area 30 .

Here, as shown in FIG. 2, the RAM 11 includes, in addition to the display flag area 30, a reverse display control table 31 and a register 32 for storing data on the number of reverse rows.

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/editing processing is input from the keyboard 13, the CPU 10 starts the proofreading/editing process from the document creation mode. Change to collection mode. c.
In order to execute the proofreading/m collection process, p u io performs a process of displaying a message for specifying a range of character strings to be moved, for example. Message data necessary for the calibration/m collection process is stored in advance in a message table in the ROM 12.

Keyboard 13 depending on the displayed message data.
When the key human power is executed, c p u i.

performs operations as shown in the flowchart of FIG.

That is, when key input is performed in step S1, CPIJ
lo determines whether the input key is a range specification key (step S2>.Here, the keyboard 13 has the following information:
Proofreading/If! A range specification key is provided that also serves as a key for executing functions. When this range designation key is operated, the CPU 10 performs a process of inverting the character strings in the designated range (step 83). At this time, the CPU
Reference numeral 10 stores each data of one column of the highlighted character string in the inverted display control table 31 of the RAM 11 shown in FIG.

At the same time, the number of inverted rows is set in the register 32 and incremented every time the number of inverted rows increases by 8.

Next, when the cursor key is operated to move the cursor to the destination of the highlighted character string, for example, c
p u io scrolls the display screen to display the character line to which the cursor is to be moved (step 34.86). At this time, when the cursor key is operated again and the display screen is scrolled, the CPU 10 determines whether or not there was a previously highlighted line in the changed display screen (step S788). . CP tJ 1G is step S3
Based on the data stored in the reverse display control table 31, it is determined whether reverse display exists on the display screen.

If the inverted display line stored in the table 31 exists within the range of the display screen, CPU IO displays the character string specified in the range in step S3 again in inverted display (step S9).

After this, when the cursor key is operated to move the cursor to the destination and the selection/execution key (enter key) is operated, the CP tJ 10 executes the process of moving the character string specified in the highlighted display, for example. (steps 811 and 812).

In this way, by storing a display line that has been previously inverted in the inverted display control table, after scrolling the display screen, when a display screen that includes the inverted display line is configured, the inverted display will be performed again. will be carried out. For this reason, for example, when a specified range of character strings to be proofread/m collection is highlighted in order to perform proofreading/editing processing such as a move function, the same range may be highlighted again even after scrolling the display screen. I can do it. Thereby, the operator can easily check the character string to be proofread/II collection once highlighted again even after it has been scrolled to another display screen.

[Effects of the Invention] As detailed above, according to the present invention, in a document creation device with a limited display screen, when scrolling of the display screen occurs after a character string in a range specified by the cursor is displayed in reverse video. However, you can re-highlight a specified range of text. Therefore, the character strings in the specified range can be checked again after changing the display screen, and the input operability associated with checking the display screen can be improved. Therefore, the efficiency of document creation and proofreading/editing processing can be improved as a result.
