Description

[Detailed Description of the Invention] [Field of Industrial Application] This document relates to a document editing device, and in particular to a document IQ collection device suitable for reading documents in document editing work using a display device with a small display capacity. Regarding.

[Conventional technology]

In recent years, small and inexpensive personal Japanese word processors (WP) have been rapidly developed. but,
These personal Japanese WPs have small display screens, as described in the separate volume OA PC r Word Processor Lover (Personal Word Processor Special Issue) published by Dempa Shimbun on January 30, 1985. Therefore, only a few characters or lines of text can be displayed at one time. As a result, it is difficult to confirm the correctness of a document that has already been input and to grasp the meaning of the preceding and following sentences when creating a document, and no consideration has been given to improving operability in order to grasp the meaning of the preceding and following sentences during input.

One way to solve this problem is to print the document that has already been input and check it.

[Problem that the invention seeks to solve]

In the above conventional technology, the content of the document is confirmed by operating screen control keys such as cursor keys multiple times to update the displayed screen content. It had the disadvantage of being difficult to use, as it required a lot of use.

Further, the method of performing trial printing not only wastes paper, but also has problems such as the inability to check the document without the printing device if the document editing device has a separate printing device.

In addition, even in a personal Tamoto language WP that uses a display device that can display several lines of character strings, one line of displayed character strings is, for example, about 10 characters, compared to about 40 characters per line of a normal document. Therefore, even though several lines of characters can be displayed, in reality, you are only viewing a portion of the document through the window, and it is difficult to read the document as a continuous string of text. The method used is to confirm the contents of the document by pressing the keys multiple times to update the contents of the display screen, which has the disadvantage of being difficult to use because it requires many key operations to grasp the meaning of the preceding and following sentences. Ta.

An object of the present invention is to provide a document editing device such as a personal Japanese WP that uses a display screen with a small display capacity.
The object of the present invention is to display a series of document character strings in an easily readable manner with a simple operation.

[Means for solving problems]

In order to achieve the above object, the present invention provides an input means with a reading key, and causes a control means to respond to the input of the reading key to enlarge and continuously scroll display a character string of a document on a display means. The present invention is characterized in that it includes a reading display control means.

[Effect]

When the operator operates the read-aloud key of the input means when he wants to confirm the correctness and meaning of the character strings of the document while editing the document, the read-aloud display means of the control means enlarges the character strings of the document while Continuously scrolling display on the display means.

Therefore, the operator can enlarge and display the read-along character string for confirming the document so that it is easy to read with a simple key operation.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

FIG. 2 is a block configuration diagram of a document editing device showing an embodiment of the present invention, and the device is comprised of a central processing unit (CPU) that controls the entire device.
PU)1, character font patterns are stored.

A character generator (CG) 2, a dictionary memory (ROM) 3 that stores a dictionary of words, etc., a program memory (ROM) 4 that stores a program that executes the function of a document editing device. A document memory (RAM) 5, which is a readable and writable memory for storing document information such as character codes, is inputted with character codes and the like. An input device 6, such as a multi-key keyboard, for example, a printing device 7 for making hard copies of documents. A display device 8, such as a liquid crystal display element capable of displaying 10 horizontal characters and 3 vertical lines, for example, for displaying input character codes, etc. and edited documents;

It consists of an overall control section 14 that houses other parts including I.

FIG. 4 is an external view of the input device 1, which includes a group of character keys 21 for instructing character input, cursor keys 22 for instructing cursor movement, document creation functions such as insertion and deletion, and functions such as printing. A group of function keys to instruct 26 and reading 24
It becomes more.

This will be explained in detail using FIG. 1 and FIGS. 5 to 12.

FIG. 1 is a processing flowchart showing a reading display process in the document editing function according to the present invention. Figure 5 is 1
3 is a flowchart showing details of display processing. Figure 6 is a diagram explaining the arithmetic processing for enlarging character data.
FIG. 7 is a flowchart of arithmetic processing.

FIG. 8 shows an example of a base document, and for convenience, a document with 22 characters x 6 lines is illustrated. FIG. 9 shows an example in which the document shown in FIG. 8 is displayed on the screen of the display device 8, and a broken line area is displayed. 51 is an image frame of the display device 8, and 52 is an editing character area.

FIG. 10 shows a screen during execution of the reading process, which is displayed in double-width, enlarged characters. During execution of the reading process, the displayed characters are made larger compared to one normal sentence IFW concentration to make it easier to read the sentences together.

Figure 11 shows the above-mentioned screen displayed as 1 by the address update process.
This is a display of the displayed character string shifted by one character.

Here, the broken lines in the screen in FIGS. 9 to 11 indicate a display frame for one character for convenience, and are not displayed on the screen. Further, although FIGS. 10 and 11 are examples in which double-width characters are clearly displayed in a solid line area, these solid lines are not displayed on the screen as described above.

FIG. 12 shows the message screen when selecting the font size.

Next, the operating procedure and internal processing for such a reading display will be explained based on FIG. 1 and FIGS. 5 to 7.

First, in process 101 of FIG. 1, it is determined whether or not there is an input from the reading key 24. If there is no input, the reading matching processing routine is exited. If there is an input from the read-aloud key 24, the process moves to step 102, and document initialization is executed to initialize the display address so as to indicate the beginning of the document.

At this time, the display screen becomes a message display state for selecting the size of the read-aloud display characters as shown in FIG.
By pressing the execution key 25 after making a selection input in step 103, the size of the reading display character is determined in step 103. Next, the process moves to process 104, where the read-out display dot data is calculated according to the selected enlargement ratio and written into the video RAM 10 (see FIGS. 6 and 7). Taking the case of a character with double horizontal size as an example, the explanation will be as follows. Characters twice the width of the characters stored in the character generator 2 are written into the video RAM 10. That is, one dot during document editing is enlarged to two dots horizontally by the arithmetic circuit 11 and written to the video RAM 10 and displayed on the liquid crystal display device 8 via the display controller 9. .

Next, in screen display processing 105, the drawing processing shown in FIG. 5 is performed, and each character (48 dots) is automatically scrolled from right to left from the beginning of the document. Here, the row direction is from right to left, but the reverse may be used. Also,
It may be from the bottom to the top or from the top to the bottom in the column direction. Next, in process 106, a process for determining whether or not the cancel key 23 has been input is executed.

This process is to cancel the reading function display, and when the cancel key 23 is pressed, the display document initial setting process 107 is executed to set the display of the beginning of the sentence as shown in FIG. 8, and then the main reading process routine is executed. end. Further, if the cancel key 23 is not pressed, it is determined in process 108 whether or not the document is finished, and if it is finished, display document initialization process 107 is executed. If it has not been completed, the display address update process 109 shifts the display character address by one character for the scroll display, and the process moves to the screen display process 105 for displaying the status.

Thereafter, the read-aloud display function is achieved by repeating the processing in the above flowchart. Here, the explanation has been given using an example of double horizontal enlargement, but it goes without saying that the enlarged size can be set freely in both vertical and horizontal directions.

According to this embodiment, an easy-to-read enlarged character string scroll display screen can be created with a single touch operation of the reading key 24, instead of the screen that was conventionally obtained by pressing the cursor key 22 multiple times, reducing operator fatigue. In addition to saving time and paper, it is also possible to easily check whether a document is correct or incorrect even in a document editing device that is not equipped with a printing device. Such a reading display function is most effective when making the text readable using a screen with a small display capacity, such as a liquid crystal display device, but it goes without saying that it can also be applied when using a CRT display device.

〔Effect of the invention〕

According to the present invention, even in a document editing device such as a personal Japanese WP that uses a display screen with a small display capacity, the flow of a series of documents can be easily read with a simple 1M operation and by displaying enlarged characters that are easy to read. can do.
