Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display control unit in a document creation and editing device.

[Technical background of the invention and its problems]

For devices based on screen editing such as conventional word processors, the number of lines of the connected display device/screen 9
Although the number of characters/line is fixed, it was necessary to change a part of the display control method, that is, the internal control program, in order to connect to a display device having a different number of lines/character/line capability. Of course, it was possible to control the display on different display devices by allowing the number of lines/number of characters on the screen/line value to be set externally as parameters without directly changing the program. By the way, display devices generally display a plurality of lines, but in recent years, editing devices having display devices with only two or one line have appeared with the aim of downsizing the device. However, when a display device has only one line, the display control method may be different from that for other cases where the display device has a plurality of lines.

In other words, in order to reduce the size and cost of the device, the control program has also been made simpler. For example, the cursor only needs to be moved in the horizontal direction (within - lines), and since the cursor cannot be moved up or down, it can be moved multiple times. While this simplifies the process by eliminating the need to control the timing of moving the cursor up and down on the screen and switching the screen scrolling, which was done in the case of line display, it also makes it easier to input characters at the end of a line. Because it is a single-line display device, it has several features, such as shifting the character string of one line to the beginning of the line to display as much of the preceding and succeeding information as possible, instead of automatically starting a new line immediately. This is a unique control unit j1 of Therefore, in order to realize a satisfactory interactive editing function by connecting another multi-line display device to the editing device originally created exclusively for the line display device, it is necessary to change not only the parameters but also the internal control program. I had no choice but to do it.

[Purpose of the invention]

The document creation/editing device provided here uses the same editing control means for both display devices with different numbers of display lines, especially line display devices and multi-line display devices, in a simple manner. A sufficient interactive editing function is realized by giving the number of display lines as a parameter only to the control means.

[Summary of the invention]

As mentioned above, in the case of a single-line display, a means is used to implement a specific interaction process, but even when a multiple-line display device is connected to the substitute, the same interaction process can be performed on a specified line of that display device, e.g. The present invention provides a document creation/editing device that displays document character strings in a central row and reads front and rear document character strings from a document memory before and after the central row, respectively.

〔Effect of the invention〕

A small word processor that is convenient to carry has a built-in one-line display device, and if necessary, a large CRT or other display device can be connected to the outside to efficiently perform editing and proofreading processing. In this case, the control program in the device may be designed for a simple one-line display device, and sufficient editing functions can be obtained by connecting many types of display devices by simply setting some parameters.

[Embodiments of the invention]

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention.

In the figure, reference numeral 1 denotes an input section for inputting characters or editing commands, to which a reed, keyboard device, tablet device, etc. are applied. Reference numeral 2 denotes a document memory for storing code information of documents sequentially input (from the input section 1). 8
4 is a display control unit that performs display control on the display device 4, a display format storage unit 6 that stores whether the display device has a side stone display ability, and a display format storage unit 6 that stores information about the currently displayed document in the memory. The display memory 7 stores character code strings of the parts. The code string in the display memory includes, for example, a control code for displaying a specific character string in reverse video, a control code for displaying a cursor, and the like. Reference numeral 5 indicates a display position 9 for the display control section, which outputs a character string inputted from the input section to a specified portion of the document memory, and interprets commands instructed from the input section and performs corresponding editing processing.
This is an editing control unit that controls the entire document creation/editing device, such as instructing inversion and instructing the cursor.

FIG. 2 is an example of a one-line display. 1 for 11 single-line displays
2 example sentences and 13 cursors are displayed.

FIG. 3 shows that the document creation/editing device of the present invention performs operations according to instructions from an editing control section originally provided for a line display device.
This is an example of display on a multi-line display device. There are 15 single-line display contents on 14 display devices and 17 document contents in front of it.
, the content of the document at the rear is displayed at 18, respectively.

The operation of the present invention will be explained below with reference to FIG.

First, when a command "Create new document" is input through the input section, the editing control section 5 clears the document memory 2 to its initial state and instructs the display control section 3 to display. At this time, the cursor position corresponds to the beginning of the document memory, and
Instructs to output the first line from the document memory 2 for display.

The display control unit 8 displays the contents of one line of the specified document in the representation unit 4.
At this time, it is stored in advance in the display format storage unit 6 whether the display device 4 has the ability to display the side stones (the number of lines TL). Accordingly, for example, if the center part C1 of the display device, that is, the value TL is in one line, it will be in the first line of the display device, and if it is in the 21st line, it will be in the first line.
This is done by specifying the position on the first line. This corresponds to 12 in FIG. 2 and 15 in FIG. The designation of the number of lines TL of the display capacity can be input in advance by the operator through the input unit 1, or a special mechanical switch can be provided when the display device 4 is connected to automatically specify the number of lines TL that is currently connected. It is also possible to provide a circuit so that the number of lines TL can determine the display rate of the display device.

Next, when the display format storage unit 6 indicates a plurality of lines, the display control unit 8 extracts a predetermined number of lines υ of the document contents in front of the currently displayed document line from the document memory 2; These are displayed in the area shown in FIG. 317. Furthermore, the contents of the document at the rear are outputted in the display area 18 in a predetermined number of rows from the document memory 2. In the present example, since the display of 12 or 15 is the first line of the document, it is necessary to control so that the special case is not displayed in the area of 17.

Next, character codes are sequentially input through the input unit 1 and stored in the document memory 2 as a character code string. The editing control unit 5 counts up the cursor position each time an input character enters, specifies the display specified line and cursor position, and instructs the display control unit 8 to display it, but if the input character exceeds one line, , move up the specified display line position. In this way, the input document is displayed on the display device 4, for example, as shown in FIG.

When a command for giving an upward instruction to the cursor 16 is input into the input section 1, the editing control section 5 selects the contents of the document memory 2 corresponding to the line currently displayed at 12 or 15. Specify the position ahead of the row position.

Of course, if the first line is currently being displayed, the specified position will not be changed.

This specified value is stored in the display specified line storage section 8, and then the display control section 8 reads out the one line document data corresponding to this specified position from the document memory 2 and displays it on the display device 4. At this time, the display format storage section 6 is referred to, and the display is displayed in the center of the screen as shown in the example 12 if the display is a - line display, or as shown in the example 15 if the display is a multi-line display.

Next, in the case of multiple display devices, the following processing is performed.

From the line specification value in the display specification line storage unit 8, subtract the value specified in the display format storage unit 6, for example 10 lines for a 21 line display device, to obtain the upper display specification value 9. For example, 10 lines are read out from the document memory 2 corresponding to the position and displayed on the display device 4 starting from the first line. Similarly, document memory 2 corresponding to the line position next to the display specified line 8.
For example, 10 lines (in the above example) are read out and displayed on the display device 4, starting from the 12th line.

Second, even if the display device 4 is a multi-line display device, for example, the center row is displayed in the same format as a single-line display device, and the screen portions before and after it are output. It is also possible to display the previous and subsequent document contents by a simple procedure.

Note that it is needless to say that the command to display the upper and lower areas of the screen does not need to be sent each time, except when specifying the upper or lower part of the cursor, that is, when scrolling the screen, or when inputting a line feed code.

It should be noted that the intention of the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

In the explanation of the above embodiment, when the display device is a multi-line display device, processing is performed by dividing the data into the upper and lower areas centering on one row of data in the center. By subtracting υ10 lines from the directivity value (the line of the document to be displayed in the center), 21 lines may be displayed from the line position of the document. At this time, the display start position is from the first line on the screen, but the power display is always in the center line.
