BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a text display method and apparatus according to the present invention.

FIG. 1 is a flowchart showing a sentence display method according to the present invention. When the text to be displayed in FIG. 1 is input from the input / output device or the storage device in step 11, the display width and the number of lines of one line of the input text are estimated in step 12. Next, in step 13, the number of sentences that can be displayed on one display line of the display means is calculated using the value of the displayable width of the display means. Then, in step 14, the display position of the sentence on the display means is determined using the value obtained in the above step, and in step 15, the sentence is displayed on the display means. Step 16
It is determined whether or not the end of the sentence to be displayed has been reached. If not, the process returns to step 14 to continue the display, and if it has, the process ends.

FIG. 2 is a schematic block diagram showing a configuration of a text display device using the text display method according to the present invention and a text editing device to which the text display device is applied. In FIG. 2, reference numeral 8 denotes a text display device, and the other portions indicate elements constituting a text editing device in combination with the text display device. In FIG. 2, the display width / line estimation unit 1 analyzes a text file input by the user using the input / output unit 4 or input from the auxiliary storage device 9 via the input / output unit 4, and The longest number of characters Ctext in which the length of one line is the longest
Is a device for estimating the number of lines in a sentence.

The display line number calculation unit 2 calculates the number of characters Cline that the display device 5 can display on one line, and the maximum number of characters Ctext on one line in the text estimated by the display width / line estimation unit 1.
Is a device for calculating the maximum number of sentences that can be displayed in one display line of the display device 5. Here, assuming that the maximum number of displayable lines is Lmax, Lmax is Cline.
The fractional part of / (Ctext + 1) is truncated. The reason why 1 is added to Ctext is to make it easier to see at least one character space between lines of the text.

The display position determining unit 3 determines each line of the text on the display device 5 based on the Ctext estimated by the display width / line estimating unit 1, the number of lines, and Lmax output by the display line number calculating unit 2. It is a device that determines whether to display at the position.

The input / output unit 4 is a device for receiving a text input from a user and reading / writing a file from / to the auxiliary storage device 9 according to an instruction from the user. Display 5
Is a device for displaying the sentence converted by the display position determining unit 3 to the user, and may be a full screen or a window.

The auxiliary storage device 9 is a portion for storing a text file to be displayed, and is controlled by the input / output unit 4. An input / output unit 4 for displaying a dialogue with a user, a display unit 5,
The auxiliary storage device 9 may be a keyboard used in a computer, a pointing device such as a mouse, a display device such as a display, or an auxiliary storage device such as a hard disk.

FIGS. 3 to 8 are views for explaining the operation of the present invention. FIG. 3A shows an image in a state where a sentence to be displayed is stored, and FIG. 3B shows a state where the sentence is displayed on a conventional display device. The sentence exemplified here is a collection of words having a short number of characters per line, and the display device is capable of displaying 10 lines of 40 characters per line. In the case of FIG. 3B, since the number of lines is 11 or more, a scroll bar 6 is displayed at the right end, and it is necessary to scroll down when viewing the first 10 lines and thereafter.

According to the method and apparatus of the present invention, the display width / line estimation unit 1 counts the number of characters between $ M, which is a line feed code, to determine how many characters each line of the sentence has. And find the maximum value among them. Also, the number of lines in the text is obtained by counting the line feed code. In the example of FIG. 3A, the first line is counted as 6 characters, the second line as 11 characters, the third line as 9 characters, and so on. Since the maximum is 12 characters on the fifth line, the display width / line estimating unit 1 passes 12 as the width Ctext and 32 as the number of lines counting the line feed code to the display line number calculating unit 2.

In this example, the number of characters Cline that the display device can display on one line is 40, and the maximum number of characters Ctext in one line in the text estimated by the display width / line estimation unit 1 is 12. The display line number calculation unit 2 performs the following calculation using these values, and Cine / (Ctext + 1) = 40/13 = 3.0.
77... The fractional part of the result is truncated to obtain a result of Lmax = 3. Then, a result indicating that a maximum of three lines can be displayed in one line of the display device is passed to the display position determining unit 3. FIG. 3C shows a display example when three lines are displayed. The determination of the display position of each line will be described later.

When there is a sentence having a line length of Cline / 2 or more, Lmax is less than 2.
In this case, since two or more sentences cannot be displayed in one line of the display device, the same processing as the conventional display method shown in FIG. 3B is performed.

The display position determining unit 3 determines where each line of the sentence is to be displayed on the display device. In determining the display position, in the first method and apparatus, as shown in FIG. 4A, the first line of the sentence is displayed from the first character of the first line of the display device to the second line of the sentence. The first line (Ctex
From the 13th character which is t + 2), the third line of the sentence is displayed from the first character on the second line of the display device, and the fourth line of the sentence is displayed from the 13th character which is (Ctext + 2) on the second line of the display device. And repeat this until the end of the sentence. FIG. 4B shows the display order of each line of the sentence at this time. It is necessary to scroll the portion that cannot be displayed in the vertical direction, but it is possible to list twice as much information as that of the conventional one.

In the determination of the display position, in the second method and apparatus, as shown in FIG. 5A, the first line of the sentence is changed from the first character of the first line of the display device to the (display of the sentence). The eleventh line which is the number of displayable lines of the device +1) is from the 13th character which is the first line (Ctext + 2) of the display device, and the second line of the text is the text from the first character of the second line of the display device. The twelfth line of (displayable number of lines of display device + 2) is displayed from the thirteenth character of (Ctext + 2) on the second line of display device, and this is repeated until the end of the text. FIG. 5B shows the display order of each line of the sentence at this time. For the portion that cannot be displayed, it is necessary to scroll in the horizontal direction, but it is possible to list twice as much information as the conventional one.

In determining the display position, in the third method and apparatus, as shown in FIG. 6A, the first line of the sentence is changed from the first character of the first line of the display device to (( The 17th line which is the number of lines of the text + 1) / 2) is the 13th character which is the first line (Ctext + 2) of the display device, and the second line of the text is the 1st character of the second line of the display device. From the above, the 18th line which is ((the number of lines of the text + 1) / 2 rounding up + 1) of the sentence is 13 which is (Ctext + 2) of the second line of the display device.
Display from the first character and repeat this until the end of the sentence. FIG. 6B shows the display order of each line of the sentence at this time. For the portion that could not be displayed, it is necessary to scroll in the vertical direction, but it is possible to list twice as much information as that of the conventional one.

Further, in the determination of the display position, the fourth method and apparatus further extend the display of the first to third methods and apparatuses in which sentences are displayed two lines at a time on one line of the display device. L calculated for each line by the display line number calculation unit 2
Display max lines at a time. As an example, FIG.
Here is an extension of the above method. In this example, Lmax is 3
Therefore, the first line of the sentence is changed from the first character of the first line of the display device to the second line of the sentence on the first line of the display device ((Cte
xt + 1) +1), the third line of the sentence is changed to the first line of the display device (2 × (Ctext + 1) +1)
, The fourth line of the sentence from the first character of the second line of the display device, and the fifth line of the sentence from the thirteenth character of ((Ctext + 1) +1) of the second line of the display device. And the sixth line of the sentence on the second line of the display device (2 × (Ctext +
1) +1) is displayed from the 27th character, and this is repeated until the end of the sentence. FIG. 7 shows the display order of each line of the sentence at this time.
(B). For the portion that could not be displayed, it is necessary to scroll vertically, but it is possible to list three times the information as compared with the conventional one.
Further, in general, it is possible to list Lmax times of information.

The above description has been made with reference to the example of the words as shown in FIG. 3A. When displaying a series of sentences, the words are displayed as shown in the display example of FIG. In addition, all of the display has been described, but it is also possible to perform editing in this display form even during editing.
