Abstract

PURPOSE:To obtain a high function by providing a printer which qualifies and prints a text character string according to character qualification codes in a storage circuit. CONSTITUTION:When a document file 105 which is already created is corrected to create a new document, a CPU 101 sends a position that an operator specifies with a cursor, etc., from the document file 105 and the display controller 103 displays the specified position of data in the document file 105. The operator performs correcting and editing operation over a look at the display and alters the document file. When the data are printed, the CPU 101 reads the data out of the document file 105, develops them into a print image, and stores the data in a printer buffer RAM 108, so that the printer 109 makes a print according to the data in the RAM 108. Consequently, a handy word processor which has good visibility and good operativity even when using a display body with a small display screen is realized.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a handy word processor.

[Conventional technology]

FIG. 6 shows the configuration of a conventional word processor.

Further, the flow of the processing will be explained with reference to FIG. The character string input from the keyboard 611 is determined by the CPU 604 as a command (for example, an instruction issued to a word processor such as printing, editing, or calling data from an external storage device) or text data (data for a document to be created). If it is determined that the data is text data, it is converted into a code and temporarily stored in a temporary file 605. The content of this temporary file 605 is written in the font R○M60 to be displayed on the display body 601 in a form as close as possible to the image when printed on the CPU 604G=J:reprinter 610.
7 is written into the VRAM 603 with reference to the character font data. Display controller 602 is VRAM603
Display data. The word processor operator views the content displayed on the display body ao1 and makes corrections and edits. At this time, in the Japanese word processor, the CPU 604 searches the dictionary ROM 608 for the kana character string inputted from the keyboard 611, converts it into the most likely kanji, and displays it. If an incorrect kanji is displayed, the operator makes corrections and finalizes the contents of the temporary file 605. The contents of the determined temporary file 605 are transferred to a document file 606 to create a document file.

The printing functions normally required in a word processor include enlarged text, underlining, knitting, superscript, subscript, ruby, reverse text, character rotation, character spacing, and line-to-line. 1 for character appearance such as spacing settings! AI functions, vertical writing, horizontal writing, right alignment, centering, justification, indentation,
In addition to functions related to document formatting, such as line breaks, half line breaks, and no line breaks, there are also ruled lines and table formatting. In this application, these are all referred to as character modifications. The document file 606 contains these character modifications. Data and string data are stored and saved together.

When creating a new document by modifying a document file that has already been created, the CPU 604 calls data from the document file 606 at a position specified by the operator using a cursor, etc., and expands the display data to display a form similar to the printed image. It is loaded into VRAM 603 and displayed.

For the print side, the CPU 604 calls data from the document file 606, develops it into a print image, and stores it in the printer buffer RAM 609. Is the printer 610 a printer buffer RA? Printing is performed according to the vi609 data. The data in the document file 606 and how it is displayed will be explained below using FIG. 8.9.

FIG. 8 is an example of a document to be created, in which characters 801 are enlarged twice both vertically and horizontally, that is, 4f=square characters are used, and the character string is placed in the center of the line by centering. Furthermore, 802 is right alignment, 803 is centering, 8
This is an example of a document in which 04 is indented by 3 characters.

Conventionally, the image displayed on the display 601 while creating such a document is approximately the same as the image printed in FIG. 9. However, since the screen of the display 601 is usually smaller than the print image, only the area within the frame 901 is displayed. The protruding portion is displayed by moving the window as shown in 902, for example, by scrolling. If the display capacity of the display unit 601 is small, the user will have to scroll many times to check the document.

As for the content of the document file 606, taking the case of FIG. 8 as an example, the following data is written, for example.

・Code indicating that the following character string will be printed in quadruple-width ゛ Code indicating that the string below until the line feed code is centered °Character code indicating each character of [Ski Tournament Notice] ・1 & square A specified release code, a line feed code, a code that indicates that the character string up to the line feed code is right-justified.

[Problem that the invention seeks to solve]

Conventional handheld word processors place great importance on portability, so they are inevitably limited by the size and functionality of the keyboard, printer, and display. Among these, the most serious problem is the display type, and if the number of displayed characters is small, the things that can be done are extremely limited. It is said that it is impossible to display a display that satisfies all of the above functions on the liquid crystal display used as the display of conventional handheld word processors. The user had to scroll to check the required 11X each time.

Furthermore, it is difficult to provide a satisfactory display that supports most of the normally required functions mentioned above, and conventional handheld word processors have had to significantly reduce their functions. For example, if you try to change the spacing between characters or lines printed in the middle of a document, the spacing between characters,
There is no way to display changes in line spacing (with conventional handheld processors, this function had to be cut down).

Therefore, in conventional word processors, as the display screen size becomes smaller, the usability becomes extremely poor as explained above, and furthermore, in terms of functionality, they are considerably inferior to desktop types that have no display limitations.

A second drawback of traditional handheld word processors is speed. When displaying, each print image is
Since the PU 604 creates the information, the load on the CPU 604 becomes heavy, and as a result, the speed of functions that require display speed such as scrolling, insertion, and deletion becomes particularly slow.

A third drawback is that the hardware is complicated.

An object of the present invention is to realize a handheld word processor that is easy to use even with a small screen display and is highly functional.

[Means for solving problems]

The handy word processor according to the present invention develops a print image according to a character code or a character modification code, and instead of displaying the print image on a display body, it converts it into character strings and character modification symbols according to the character code or character modification code and displays it. There are characteristics.

[Effect]

Therefore, document formats such as enlarged characters, interlacing, centering, etc. can be displayed even if the display is smaller than the print image, and the CPU does not need to develop the print image each time it is displayed, increasing the speed.

(Example 7iiiσq) Fig. 1 is a block diagram showing the configuration of a handy word processor according to the present invention. Fig. 2 shows the flow of processing.

The character string input from the keyboard 110 is
I determines whether it is a command or text data, and if it is text data, it is converted into a character code or character modification code and temporarily stored in the temporary file 104. The contents of this temporary file 104 can be modified by the user or
A document file 105 is transferred to display the contents of the temporary file 104 so that selection of kanji in the case of Japanese can be performed, and appendixes are added to the end. The display controller 102 causes the display 102 to display the day and night of the document file 105. The word processor operator views the content displayed on the display 102 and makes corrections or edits. At this time, the Japanese word processor also converts the kana character string into kanji 9'su. Create a document file as described above.

In order to create two new documents by revising a document file that has already been created, the CPU 10I informs the display controller 103 of the position specified by the reoperator from the document file 105 to the cursor, etc., and the display controller 103 reads the document file 105. The data at the designated position of data 105 is displayed. The operator changes the document file by making corrections and edits while looking at the display.

At print+15, the CPU 10I calls data from the document file 105, develops it into a print image, and stores it in the printer buffer RAM 108. The printer 109 performs printing according to the data in the printer buffer RAM 108.

FIG. 3 shows the display of the handy word processor according to the present invention.

・Symbol 301 that indicates that the character string below is to be centered until the line feed code comes. ・Symbol 302 that indicates that the following string of characters is to be printed in quadruple-width. ・Character string 30 that indicates each character of "Notice of Ski Tournament"
3 - Symbol for canceling double-width specification 304 - Symbol 308 indicating a line feed - Symbol 305 - indicating that the character string up to the line feed code is right-aligned 306 - Each character of "secretary" 306 - Line feed symbol 308 The following are displayed in the same way. . 307 is an indentation symbol. In addition, character modification control as shown in FIG. 4 as an Ikkan table can be considered. By assigning codes and symbols in this way, the contents of the document file 105 can be displayed.

Since the screen size is limited, the actual size is 309.31.
Only the area within the frame such as 0 will be displayed. You can check the protruding parts by scrolling vertically.

FIG. 5 is a diagram showing in detail the display controller 103, document file 105, and display body 102 shown in FIG. The multiplexer 502 replaces the display address generated from the address bus from the CPU 101 and the address counter 501 and specifies the address of the document file 105. The document file 105 is a RAM that also functions as a video RAM. Address counter 501 generates the necessary addresses for the requests in the order of display.

The multiplexer 502 is switched to the CPU 101 side when the CPU 101 attempts to update the contents of the document file 105. The document file 105 outputs the character code of the designated location to the address counter 501 in accordance with the order of display, and transmits it to the display pattern generator 504. The pattern generator 504 is a character generator that converts character codes and character modification codes into characters and character modification symbols. The display controller 103 includes a display pattern generator 504, a parallel-serial conversion circuit 505, and a display driver 506. A parallel-serial conversion circuit 505 converts font data output in parallel to drive the display 1102 into serial data and transfers it to the display driver 105.

The embodiments of the present invention have been described above. For example, the display controller 103 is provided separately with the video RAN1 as in the conventional example, and the CPU101 is attached to the front of the video RAM.
The video RAyri data may be sent while referring to the data of M106. In addition, although the document file 105, temporary file 104, and printer buffer RAM 108 are drawn separately in FIG.
The same RAM is used as the work area, etc. Similarly, font ROM106 and dictionary ROM107 are also CPU10I.
These programs are often stored in the same ROM.

In addition, it is also possible to define controls such as a symbol that temporarily stops printing when printing reaches the location of that symbol as a character modification symbol, or a control that sounds a buzzer to alert the user.

〔Effect of the invention〕

By adopting the configuration described above, for example, when displaying enlarged characters or changing line spacing or character spacing in the middle of a document, displays that previously required a large display space can now be displayed using normal-sized characters. Since the display space can be used in vain, more information can be given to the user using a limited number of display bodies, and a handy word processor that is easy to use can be realized.

Furthermore, when displaying small characters such as ruby, superscript, and safscript, it was not possible to display them adequately due to lack of display resolution in the past, but with the method of the present invention, normal full-width characters can be used. can be displayed.

Furthermore, there is no need for special fonts or routines.

Furthermore, when displaying, the CPU 10I does not need to read the print image each time, and only needs to transfer the contents of the document file to the display, reducing the load and greatly increasing the processing speed.

The hardware configuration is also commercially available, as shown in FIG.

As mentioned above, according to the present invention, a handheld word processor with good visibility and operability can be realized even when a small display screen is used.
