Description

[Detailed Description of the Invention] [Industrial Application Field] This invention has a display device as a man-machine interface like a word processor, and uses an interactive input method to input the character code of each character composing a sentence. The present invention relates to a text creation device that inputs data and stores it in a refresh memory.

[Conventional technology]

FIG. 3 is a block diagram showing the configuration of a conventional device, in which (1) is a display device and (2) is an image processing device [1, +3
1 is an input device. However, parts of the explanation of this invention that do not include membership fees are not shown in FIG.

From the input device (31), the character code of each character constituting the sentence is input using keys according to the arrangement and initialization of each character in the sentence.Directly inputting the character code of a kanji does not mean that the character code of the kanji is It is well known that searching for character codes can be troublesome, so the user inputs the character code of the kana character that represents the reading of the kanji and converts it into the kanji character code in the input device (3). It is a place.

A transceiver memory is provided in the image processing device (2), and the input character code is sent to the display device (1) of the character.
The address position corresponding to the display position above is stored. In addition, the image processing device (21) is equipped with a font memory, and for every character used in this system, the character code of the character is used as an address, and the image pattern of that character (dratonog turn) is stored in the font memory. ), and the character code stored in the refresh memory is read out in synchronization with the raster scan of the display device (1) and displayed on the display device [11] as an image pattern of the character via the font memory. That is, the characters that the operator inputs from the input device (3) are in the form of character codes, and when they are processed and stored in the machine, they are in the form of character codes, but in order for the operator to confirm the input characters. , the character code must be converted into an image pattern of the character and displayed on the display device (1).In addition, depending on the design, an image memory (sometimes called frame memory) is installed between the refresh memory and the display device. The image memory stores one piece of data for each pixel (the minimum display area unit is called a pixel) on the display screen of the display device fi1 (11).

When displaying the gradation or color of a pixel, the data corresponding to one pixel is multi-bit, but when displaying black and white, the data for one pixel only needs to be one bit. Word processors often use black and white cathode ray tubes and do not display gradations of light and shade, so one bit is sufficient for each pixel.

When storing an image memory, convert the character code read from the refresh memory into the character number turn of the relevant character using the font memory, input it to the image memory, and store it in the image memory in synchronization with the display on the display device (1). is read out and the brightness of the display device (1) is modulated.

By the way, due to the layout of the text, etc., the display device (1
) may be entered so that the text is displayed only on a portion of the screen. FIG. 4 is an explanatory diagram showing an example of such partial display input. Both the font memory and the image memory are provided to correspond to the entire display screen m [41K] of the display device (1), so if only a part of the section (5) is used, only the corresponding section will be used for the refresh memory and the image memory. It will become unnecessary.

FIG. 5 is a flowchart showing the operation of the input device (3) when performing input for display in the section (5) shown in FIG. 4, and (51) to (54) indicate each step. Character codes (characters, symbols,
The code that includes figures and represents them is called character code)
The data is written to a predetermined address location in the refresh memory, and the write address changes as shown in FIG.

[Problem that the invention seeks to solve]

Since the conventional device operates as described above, the return key and space key must be used many times in order to input an input to display only one section (5) as shown in FIG. However, there were problems in that the operation was complicated and there were many opportunities for erroneous operation.

This invention was made to solve the above problems, and in the case of input that is displayed in one section on the display screen,
The purpose is to obtain a text creation device that is easy to operate for an operator.

[Means for solving problems]

In this invention, the start address and end address in the X direction and the start address and end address in the Y direction of the refresh memory corresponding to the display section are input and stored in advance, and the write address of the refresh memory 7 is stored in this memory. It is now controlled according to the starting and ending addresses.

[Effect]

Since the write address of the refresh memory is automatically controlled, input operations by the operator are facilitated.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram showing an example of an address table in an embodiment of the present invention, in which the starting address in the X75 direction is added,
Direction start address is O5X direction end address is 40, Y
An example is shown in which the direction end address is set as IO. Refresh memo IJ[ stores one character code per address, so in the example shown in Figure 1, the characters displayed in section (5) in Figure 4 are in the first row (corresponding to Y-direction start address 0). ) to 11th line (Y direction end address IO
(corresponding to K), the 21st column (corresponding to the addition of the X-direction start address) to the 21st column (corresponding to the X-direction end address addition). The table shown in FIG. 1 is input in advance from the input device (3) and stored in the image processing device (2).

FIG. 2 is a flowchart showing address control when inputting using the table shown in FIG.
7) represents each step.

At the time of initialization, both the X-direction address and Y-direction address are set to O in the flowchart of FIG. 5, but in the flowchart of FIG. 2 showing the operation of this invention, the X-direction address is set to 20 ( The start address in the X direction) and the Y direction address are set to 0 (start address in the Y direction). Immediately after, step (22) → (23) → (24) is executed without pressing the return key.
Returning to step 25), the character code is written into the refresh memory in the address range shown in FIG. 1, and this refresh memory is successively read out to display the character image pattern in the range shown in block (5)K in FIG.

Note that in the above embodiment, one type of table is defined and characters are displayed in one section as shown in Fig. 1, but it is also possible to define multiple types of tables and control the display of characters in multiple sections. Can be done.

〔Effect of the invention〕

As described above, according to the present invention, the start address and end address in the X direction and the start address and end address in the Y direction of the refresh memory are input and stored in advance, and the write address of the refresh memory is controlled according to the stored information. Therefore, input operations by the operator become easier.
