Abstract

PURPOSE:To easily discriminate the characters which are fetched by a buffer from those characters which are not fetched by the buffer by displaying only the fetched characters with inversion. CONSTITUTION:A selection means deletes the characters which are divided by the ruled lines forming a rectangular area among those characters included in this rectangular area. An inversion display means displays the other characters with inversion i.e., the inversion between the black and white levels, in the rectangular area. Thus an area including the characters fetched actually by a buffer is clearly displayed among the characters included in the rectangular area. As a result, it is possible to easily discriminate the characters to be fetched by the buffer from those not to be fetched even though the positions of characters set at the left and right edges of the rectangular area are not even on each line and some characters overflow this area.

Description

[Detailed Description of the Invention] [Prior Art] A conventional Japanese word processor with a rectangular processing function inputs character data within a specified rectangular area on the screen into a buffer as shown in FIG. If the positions of the characters at the left and right ends of each line are uneven and there are characters that are divided by the ruled lines forming the rectangular area, the character data within the rectangular area is displayed in reverse as shown in Figure 3. Also, it was difficult to grasp the area of character data that was actually taken into the buffer.

[Problems to be Solved by the Invention] An object of the present invention is to make it possible to easily distinguish between character data that is actually imported into a buffer and character data that is not imported, when character data in a rectangular area is imported. Our goal is to provide a Japanese word processor.

[Means for Solving the Problems] The object of the present invention is to provide a Japanese word processor having a rectangular processing function, which processes characters that are not divided by the left and right ends of the rectangular area on the screen. This is achieved by a Japanese word processor characterized by comprising means for selecting, means for displaying the selected character by the means in reverse video, and means for capturing the selected character into a predetermined buffer.

[Action] Among the characters within the rectangular area, the characters that are divided by the ruled lines forming the area are removed by the selection means. The reverse display means reversely displays the remaining characters in the area, ie, inverts the black level and the white level, so that the characters actually captured in the buffer can be easily distinguished from the characters that are not captured.

[Embodiment 1] An example of the operation of capturing character data in a rectangular area by the Japanese word processor of the present invention will be explained in detail below using the flowchart of FIG.

First, in step S1, it is determined whether the leftmost character of the first line indicated by symbol A in FIG. investigate. If it is detected that the character protrudes to the left, step S2 calculates the half-width number (3 in this case) between the right end of the lever character and the left end of the rectangular area.

Next, the coordinates of the inversion area (left end of the first row) and the number of digits are corrected based on the values calculated in step S3.

Next, in a similar manner, in step S4, it is checked whether or not the rightmost character of the first line indicated by symbol B in FIG. 4 within the rectangular area protrudes to the right from the area.

If it is detected that the character is protruding to the right, the half-width number (1 in this case) between the left end of this character and the right end of the rectangular area is calculated in step S5, and the number is calculated based on the value calculated in step S6. Correct the coordinates of the inversion area (right end of the first line) and number of digits.

In this way, the inverted display area of the first row within the rectangular area is determined.

Next, in step S7, it is checked whether or not the line for which the above processing has been executed is the last line of the rectangular area, and if it is not the last line, the process returns to step S1 and the above processing is repeated for the next line. .

By performing such processing up to the last line, the inverted display area for all lines within the rectangular area is determined.

FIG. 5 shows the results of the above processing. As shown in the figure, since only the characters that are actually taken into the buffer are displayed in reverse video, it is possible to easily distinguish between the characters that are taken in and the characters that are not taken in.

In the above embodiment, the characters to be imported into the buffer are displayed in reverse video, but if characters to be imported and characters not to be imported can be clearly distinguished, other displays other than the reverse display may be used. method may also be used.

[Effects of the Invention] The Japanese word processor of the present invention clearly displays the character area to be imported by highlighting only the characters that are actually imported into the buffer among the characters in the rectangular area.
Even if the positions of the leftmost and rightmost characters in a rectangular area are uneven in each line and there are characters that protrude from the area, it is possible to easily distinguish between characters to be imported and characters not to be imported. have

FIG. 1 is a flowchart for explaining the operation of importing character data in a rectangular area by the Japanese word processor of the present invention, FIG. 2 is a diagram showing character data in a rectangular area, and FIG. FIG. 4 is a diagram showing a state in which character data within the area is displayed in reverse. FIG. FIG. 4 is a diagram showing an example of inverted display when character data in a rectangular area is taken in by a word processor.
