Abstract

PURPOSE:To make the inputting operation of a character processor easier, by displaying the leading line of a page being currently processed when only page retrieval is designated without designating the number of pages to be retrieved. CONSTITUTION:When data inputted from a keyboard (KB)11 is that indicating page retrieval, a word processor controlling section 3 shifts the control to a page retrieval controlling section 5. Then, at the page retrieval controlling section 5, the number of pages designated from the KB11 is discriminated and each data from the leading line of the designated page are successively displayed from the leading location of the display picture of a CRT7. When no page is designated from the KB11, the controlling section 5 retrieves a page being currently displayed on the CRT7 from the leading line and displays the control so that each data from the leading line are displayed on the display picture of the CRT7 from the leading location. In this case, the number of the pages being currently displayed is stored in a displaying page register 5a and the page retrieving process is terminated. At this time, a cursor also moves simultaneously to the leading line of the displayed page.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention particularly relates to a character processing device having a page search function.

BACKGROUND TECHNOLOGY Conventionally, when performing a page search in this type of character processing device, the displayed page is generally moved to the previous or next page using a key that instructs page movement, or the number of pages to be searched is entered using a page number designation key. When the specification was omitted and a page movement instruction was given, the displayed page was moved to the next page. However, when you want to move the cursor to the first line of the page currently being processed with a conventional device, and the first line of the page is not displayed, you will not only be asked to move the page, but also specify the number of pages to display or the line. This has the disadvantage that it requires instructions to move, cursor movement, etc., making the operation extremely complicated.

Purpose Therefore, the purpose of the present invention is to eliminate the above-mentioned drawbacks, and to provide a system in which when only page search is instructed without specifying the number of search pages, the first line of the page currently being processed is displayed so that editing can be continued. The object of the present invention is to provide a character processing device that is easy to operate.

Example Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of the configuration of the character processing device of the present invention, where 1 is a central processing unit (hereinafter referred to as CP'U), and 1 is stored in an internal control memory (hereinafter referred to as ROM) 1a. It performs calculations, logical judgments, etc. for character processing according to a program (control procedure), and controls each component connected to the bus BS, which will be described later.

A character generator (hereinafter referred to as CG) 2 stores character patterns to be displayed, and generates character signals such as characters, symbols, and cursors to be displayed.

Reference numeral 6 denotes a word processor control unit, which performs document input, insertion, deletion, and other document creation and editing processing. 4
is a buffer that stores character data such as input document information.

5 is a page search control unit that controls page search processing;
a is a display page register that stores the number of currently displayed pages. 6 is a display control unit (hereinafter referred to as CRTC) that drives and controls a display device (hereinafter referred to as CRT) 7;
Control is passed to the word processor control unit 6, and the character code data stored in the buffer 4 is converted into pattern data by referring to the CG2, and
to display characters or symbols. At this time, X%CRT
The C6 also refers to the display page register 5a and also performs control to display the page number on the CRT 7.

8 is a floppy disk control unit (hereinafter referred to as FDC) that controls a floppy disk (hereinafter referred to as FD) 9; 10 is a keyboard control unit (hereinafter referred to as KB) that controls a text input keyboard (hereinafter referred to as KB) 11; , K.B.C.
12 is a printer control unit (hereinafter referred to as PRC) that controls a printer (hereinafter referred to as PR) 16 that prints the created document. KBll is equipped with a group of keys for character input consisting of alphabet keys, kana keys, etc., and a group of keys for inputting funxylon consisting of cursor keys, various control instruction keys such as page search, etc. Key information input from these keys is stored in KBCl. The data is then read by the CPU 1 or the word processor control section 3.

If the data input from KBli is page search instruction data, the word processor control section 6 transfers control to the page search control section 5. Next, the page search control unit 5 determines the number of pages specified by KBjj, and sequentially displays each data from the first row of the specified page from the first position on the display screen of the CRT 7. Additionally, if there is no designated page instruction from the KBll, the first line of the page currently displayed on the CRT7 is searched as described later, and each data is displayed from the first line on the CRT7 display screen. Control the display as follows. At this time, the number of currently displayed pages is stored in the display page register 5a, and the page search process is ended. At this time, the cursor also moves to the first line of the displayed page.

In this way, when it is determined that the input data to the word processor control section 6 (secondary ka) is a page search command input, control is passed to the page search control section 5. FIG. 2 shows an example of the contents of the node 4, the display page handling register 5a, and the display device 7 and the position of the cursor 7a at the time when the control is passed, and the contents of the register 5a at this time @6
" indicates the page position of the file 4, and is displayed on the display device 7 as "page 6" indicating the number of currently displayed pages.

Next, an example of the operation of the page search control unit 5 shown in FIG. 1 will be described in detail with reference to the flowchart in FIG. 6.

First, when control is passed from the word processor control unit 6, the page search control unit 5 performs data input processing in step 831 until the data input is completed, and checks whether data indicating the specified number of pages has been input. Make a judgment. If the specified number of pages has been input, step 831 becomes an affirmative determination and the process proceeds to step 832; if the specified page number has not been input, step S31 becomes a negative determination and the process jumps to step S33.

In step S32, the input designated page number is stored in the display page register 5a, and the process advances to step S33. Now, in the state shown in Figure 2, the specified number of pages is °゛2′”
is input, the contents of the display page register 5a are replaced with "2" as shown in FIG. 4 in step S32 described above. In the next step S33', the first line for the number of pages stored in the display page register 5a is searched from the buffer 4 (see FIG. 2). One screen worth of data from the first line found in step S'33 and the contents of the display page register 5a are displayed on Z. At the same time, the position of the cursor 7a is also moved to the first column position of the first row (see FIG. 4(A)).

If the specified number of pages is not input, the process jumps from step S31 to step 833 as described above, so the contents of the display page register 5a remain unchanged (see FIGS. 2 and 4).
(see figure (B)), step 833 and step S34
As a result of the process, the display screen of the display device 7 is switched to the display screen of the first row of the currently displayed page, and the cursor 7a is
The position of is moved to the first digit position of the first row (see @ Figure 2 and Figure 4 (B)).

After the above processing, control returns to the word processor control section 6, and the above page search processing is repeated again as necessary.

In this way, according to this example, when only issuing a page search command without specifying the number of pages to be searched, the display starts from the first line of the currently displayed page and the cursor position also moves to the first line. This simplifies input operations,
Your usage will improve.

Effects As explained above, according to the present invention, when performing a page search, when the document on the page currently being created or edited spans several pages, the input operation procedure is extremely simplified and the document on the current page is searched. A character processing device that can easily search and display the beginning of a text can be obtained.
