Description

[Detailed Description of the Invention] [Field of Industrial Application] This document relates to a text: IF editing device, and is particularly suitable for document editing in a document editing device using a display device with a small display capacity. Regarding equipment.

[Conventional technology]

In recent years, small and inexpensive personal Japanese word processors (WPs) have been rapidly developed. but,
These personal Japanese WPs were published by Dempa Shimbun on January 30, 1985, for example.Since the display screen of the display device is small, only a few characters or several lines of character strings can be displayed at one time. Therefore, it is difficult to check whether the document you have already input is correct or to grasp the meaning of the preceding and following sentences when creating a document.

Further, no consideration was 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. Many times.

It had the disadvantage of being difficult to use.

In addition, the method of making trial prints not only wastes paper, but also requires printing bags for document editing devices with separate printing devices.
f! There were problems such as not being able to check documents without it.

Even if characters can be displayed, in reality, only part of the document is viewed through the window, and it is difficult to read the text as a series of continuous text strings. The method used is to check the contents of the document while updating the screen contents, which requires many keystrokes to grasp the meaning of the preceding and following sentences.

It had the disadvantage of being difficult to use.

SUMMARY OF THE INVENTION An object of the present invention is to display a series of document character strings in a manner that is easy to read with simple operations even on a document editing device such as a personal Japanese WP that uses a display screen with a small display capacity.

[Means for solving problems]

In order to achieve the above object, the present invention provides a read-aloud key on an input means, and causes a control means to continuously display a character string of a document in a partial display area of a display means in response to input of the read-aloud key. The present invention is characterized in that it is provided with reading display control means for scrolling display.

[Effect]

When the operator operates the reading key of the input means when he wants to check the correctness and meaning of the character strings of the document during document editing, the reading display means of the control means displays the character strings of the document on the display means. Continuously scroll display in some display areas.

Therefore, the operator can display nine character strings for checking the document 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.
(CPU)1. A character generator (CG) 2 that stores font patterns of characters, a dictionary memory (ROM) 3 that stores a dictionary of words, etc. A program memory (ROM) 4 that stores programs that perform functions as a document editing device, a document memory (RAM) 5 that is a memory that can be read and written at any time to store document information such as character codes, character codes, etc. Enter. For example, an input device 6 such as a plurality of key-type keyboards, a printing device 7 for making a hard copy of a document, input character codes, etc., and an edited document are displayed.

For example, a display device W8 such as a liquid crystal display element capable of displaying 10 horizontal characters and 3 vertical lines. A video memory (RAM) 10, which is a memory corresponding to each display dot of the liquid crystal display device which is the display device 8, drives the liquid crystal display element 8 of the display bag R8 dot by dot based on the contents of the video RAM10. It consists of a display controller 9.

In the above configuration, when the power of the document editing device is turned on, the document editing function is executed by the CPUI and the program ROM 4, and the characters corresponding to the character codes etc. input from the input device 6 are compared with the dictionary in the dictionary ROMa. Then, read out the font pattern of the corresponding character from CG2 and store it in the video RAM.
Store in l0. The contents stored in the video RAM 10 are as follows.

Displayed on the liquid crystal display device 8 by the display controller 9.

The document is edited by repeating the above process.

The document is stored in document RAM5. Printing of the document is executed by the CPU 1 driving the printing device 7 via a driver (not shown).

FIG. 3 is an external view of a document m actual device according to an embodiment of the present invention, showing an input device 61 a display device 8. The printing device 7, the case 13 that houses the device group, and the CP explained in FIG.
It consists of an overall control section 14 that houses other parts including the UI.

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. It consists of a group of function keys 27 for instructing and a reading key 24.

Next, the reading function will be explained in detail using FIGS. 1 and 5 to 10.

FIGS. 1 and 5 are process flowcharts showing part of the reading display process in the document editing function according to the present invention. FIG. 5 is a flowchart showing details of display processing.

FIG. 7 shows an example of a base document, and for convenience, a document with 22 characters x 6 lines is illustrated. FIG. 8 shows an example in which the document shown in FIG. 7 is displayed on the screen of the display device 8, and a broken line area is displayed. 51
5 is an image frame of the display device 8, and 52 is an editing character area.

FIG. 9 shows a screen during execution of reading-aloud processing, in which the top one line is used as the reading-aloud display area 53, the lower two lines are not displayed, and only one line is projected on the display device 8, and reading-aloud display is being executed. This makes it easier to read together.

In this embodiment, one row at the top of the display device 8 is used as the reading display area, but the one display area is not limited to this.

Item 10 is the display address update process that displays the screen mentioned above.
This is a display of the displayed character string shifted by one character.

Here, the broken lines in the screen in FIGS. 8 to 10 indicate a display frame for one character for convenience, and are not displayed on the screen.

Next, the operating procedure and internal processing for such read-aloud display are explained in 1 based on the processing flowcharts in FIGS. 1 and 5 and the address correspondence diagram of the video RAM 10 in FIG. 6.
This will be explained using an example in which characters (24 dots) are shifted to the left.

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.

Here, as shown in FIGS. 5 and 6, the display area is the part surrounded by addresses 1 to 28 and 1 to 2353 in the vertical direction of the video RAM 10, and the part surrounded by 29 to 84 in the vertical direction and 29 to 2381 in the horizontal direction. The display controller 9 and the video RAM 10 are initialized so that the displayed area is not displayed.

Thereafter, by executing the one-screen display process 103, the image is displayed on only one line on the screen of the display device 8, as shown in FIG. Next, when the execution key 25 is pressed, the display address is updated in process 106 through processes 104 and 105, and the display character string is shifted by one character as shown in Fig. 10, and one display character string is automatically moved from right to left. Scroll to.

Here, it is from right to left in the row direction, but the reverse case is also possible6Also, it may be from bottom to top or from top to bottom in the column direction.Whether or not the cancel key 23 is input in the primary process 104 Execute the determination process. This process is for canceling the display of the read-aloud function, and when the cancel key 23 is pressed, the process moves to process 107 to execute the display document initial setting process and set the display of the beginning of the sentence as shown in FIG. After that, the main reading processing routine ends. If the cancel key 23 is not pressed, it is determined in step 105 whether or not the document has ended, and if the document has ended, display document initialization processing 107 is executed. If it has not been completed, the display address update process 106 shifts the display character address by one character in the same manner as described above, and the process moves to the screen display process 103 for displaying the status. Thereafter, by repeating the above processing flow, the read-aloud display function is achieved.

According to this embodiment, an easy-to-read one-line display screen can be created by one-touch operation of the reading key 24, instead of the conventional screen obtained by pressing the cursor key 22 multiple times, thereby reducing operator fatigue. In addition to saving time, saving paper, and even in a document editing device that does not have a printing device, it becomes possible to easily check whether the document is correct or not. 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 displayed in a manner that is easy to read with a simple stroke.
