Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a data processing device such as a host computer that is connected to a data communication line for transmitting and receiving data, and is used to transmit data from the data processing device. The present invention relates to a data display method for displaying characters, figures, and pictures on a display screen of a main unit according to the present invention in accordance with code data.

2. Description of the Related Art In conventional display devices, a data processing device such as a computer, which corresponds to a host, and a terminal device connected via a data communication line display characters and graphics according to code data sent from the host computer, etc. It has a display screen that can display characters and pictures, and when displaying characters on this display screen, the size of the characters is the size normally used, and the width of the characters is the size normally used. It is possible to switch to smaller fonts for display, and when switching to smaller fonts, more characters can be displayed on each line of the display screen than normally possible when displaying fonts of the size used. However, it is up to the operator to switch this mode to display normal-sized characters on the display screen, or to display characters with a width smaller than normal size on the display screen. This was done by operating the attached keyboard.

Problems to be Solved by the Invention With such a conventional display device, when some data is output from a host computer to the display device and the user attempts to read the contents, the operator must do the following in advance.
You must know whether the number of characters in one line of the content that will be displayed now can fit in one line when displayed using characters of the size normally used, or if you do not know, predict and display it from now on. If you feel that the content will fit on each line sufficiently using the normally used font size, use the display device to display the content in the normally used font size.
On the other hand, if you think that the characters on a certain line may not fit on one line of the display device when you use characters of the normal size, you can change the mode in advance and change the width to characters that are smaller than the characters normally used. I had to switch and use this display.

And if your predictions are wrong and the number of characters on each line of displayed data does not fit even though you thought it would fit using the display device's normal font size, then Characters that were originally missing were truncated and were not displayed, or characters that were originally one line were automatically split into two lines and displayed, making them difficult to read.

On the contrary, I thought that the number of characters in each line of displayed data could not be accommodated by using characters of the size normally used on the display device, so I decided to change the mode and display it in characters with a smaller width. Despite using this display device, in reality, when all the data to be displayed on each line fits even if the font size is normally used, it is actually necessary to use the font size that is normally used. Even though I could have used it, I ended up checking the contents by looking at it in small, hard-to-read fonts, which made it extremely difficult to use. It was something.

Means for Solving the Problems In order to solve the above problems, the present invention allows the operator to switch between using characters of the normally used size and characters with a smaller width. can be done using the keyboard included with this display device, and
Furthermore, the microcomputer that controlled the entire display device had a memory for remembering the number of characters in each line of the display screen currently being displayed, and the contents of this memory used characters of the size normally used. Therefore, when the line cannot fit within the range of one line, the control signal output from this microcomputer automatically causes the display to be made using characters smaller in width than the normally used characters. I am having trouble changing the data display method.

Effects of the present invention With the above-described configuration, the operator can set the mode in advance to display characters smaller in width than the characters normally used, and check the contents of the displayed data by looking at the small characters. At the beginning, the letters are of the usual size,
Display the large and easy-to-read letters on the tab,
In this mode, as soon as a line of data that does not fit on one line is sent, the microcomputer that controls the entire display device determines this and automatically changes the width of the data to characters that are wider than the characters normally used. Switch to the mode that displays small letters, and display the data sent from the computer, etc. that corresponds to the host, on the display screen.

Embodiment □ FIG. 1 is a block diagram showing an embodiment of a display device related to the data display method of the present invention. In FIG. 1, data processed by a host computer 6 is input to an input/output port 7 through a data communication line 6.

Further, from this input/output port 7, the signal is input to the control microcomputer 3 which controls the entire display device of this embodiment. This control microcomputer 3 recognizes the sent data one by one, and if control data is sent, it performs control accordingly, and when display data is sent. When the data comes, characters corresponding to the data are stored in this display memory 2.

The character data stored in the display memory 2 is displayed on the display screen 1 as is. Every time display data is sent, the control microcomputer 3 stores it in the display memory 2 and at the same time stores the contents of the memory 11 for storing the number of characters being displayed on each line, which is part of the control memory 8. will be updated.

At this time, when the mode is to display characters of a normally used size, the character data to be displayed in the display memory 2 of Figure 1 is stored in the form shown in Figure 2, and it is stored as shown in Figure 4. It is displayed on the display screen 1 of FIG. 1 in the form shown in FIG.

In this way, each time character data for display is sent to the host computer 6 in FIG. 1, the contents of the memory 11 for storing the number of characters being displayed on each line are updated. This updating method is such that when normal character display data is sent, each line in the memory 11 for storing the number of characters being displayed is incremented by one for the line currently being displayed. if,
The control code that represents all line breaks is in the host computer 6.
When the text is sent, the contents of the part of the line currently being displayed in the memory 11 for storing the number of characters being displayed on each line are fixed in their current state, and the character data for the next display is stored for display. It is stored in a location corresponding to the next row of memory 2, and
From then on, the contents of each line of the memory 11 for storing the number of characters being displayed, corresponding to the next line, are incremented by one.

In this way, while updating the contents of each line of the memory 11 for storing the number of displayed characters, the control microcomputer 3 constantly updates the contents of each line of the memory 11 for storing the number of displayed characters of the currently displayed line. Compare the contents of the memory 9 for storing the number of characters that can be displayed in one line using normally used characters, and if the contents of each line of the memory 11 for storing the number of characters currently being displayed are larger than the contents of the currently displayed line. , the control microcomputer 3 switches the display mode to make the width of the displayed characters smaller than the size of the characters normally used. Specifically, the contents of the display memory 2 shown in FIG. 1 are changed as shown in FIG. 3. When changed in this way, the display contents of the display screen 1 in FIG. 1 become as shown in FIG. 6, an example of the display. As you can see from this example, in this example, when the character data is displayed using characters that are much smaller in width than when they are displayed using the normal character size, character data with exactly twice the number of characters is displayed in the first It can now be displayed on each line of the display screen 1 in the figure.

tb, compared to the contents of the memory 9 for storing the number of characters that can be displayed in one line using characters of a normally used size, the contents of the memory 10 for storing the number of characters that can be displayed per line using characters whose width is smaller than the characters normally used are as shown in FIG. This means that it is exactly twice as large.

A keyboard 4 in FIG. 1 is a keyboard attached to the display device of this embodiment, through which an operator inputs data by pressing keys and sends the data to the host computer 6 in FIG.

Effects of the Invention As described above, according to the present invention, with an extremely simple circuit configuration, it is possible to read the contents of data sent from a computer, etc., usually in large, easy-to-read characters, and When a large amount of data is sent that cannot fit on one line in large characters, it is automatically displayed in smaller characters with a wider width, which is extremely useful in practical terms.
