Abstract

PURPOSE:To specify a document to be edited easily even when character size, spaces between characters and spaces between lines are different by storing constitutional elements in every line of a displayed document. CONSTITUTION:A document editing device consists of a display device 1, a specification device 3 to specify the display part of the display device 1, a storage device 5 to store the document in displaying at an editable format, a structure storage device 4 to store the structure of the displayed document, and a CPU2 to control said devices to make the displayed document correspond to the contents of the storage device 5. An arithmetic unit 2 inputs information such as character size, character space and line space from the storage device 5 while referring the contents of the structure storage device 4. On the basis of the information from the device 2, a required character is pointed out from the storage device 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a document editing device that facilitates pointing of a document including a plurality of character sizes, character spacings, and line spacings.

[Technical background of the invention and its problems] Conventionally, word processors have limited the number of characters that can be displayed on the display screen regardless of character spacing or line spacing (however, two half-width characters correspond to one full-width character, and one double-width character corresponds to two full-width characters). has been decided. For example, in a screen with 12 lines x 36 characters, the display screen is divided into 12 x 36 matrices, as shown in FIG. 1(a). On the other hand, as shown in FIG. 1(b), the document data is stored in a format corresponding to a virtual 12x36 matrix.

If the part shown in FIG. 1(a) is pointed, the character at the same location in the matrix, in this case "to", is indicated from FIG. 1(b).

In such a method, for example, two half-width characters are included in one element of the matrix, and the half-width character must always be corrected to two characters. Therefore, since pointing can only be performed in units of elements in a 12×36 matrix, cases in which the same document contains multiple character sizes, character spacings, and line spacings cannot be handled.

[Object of the Invention] In view of the above circumstances, an object of the present invention is to provide a document editing device that allows easy pointing even when there are multiple character sizes, character spacings, and line spacings.

“Embodiments of the invention” An embodiment of this light will be described below with reference to the drawings.

In FIG. 2, a display device 1 consisting of, for example, a CRT display, capable of displaying not only a single font size, character spacing, and line spacing, but also multiple font sizes, character spacing, and line spacing, text, figures, and tables, and a display device 1 are shown. An instruction device i13 comprising, for example, a tablet or a joystick, for instructing the relevant part on the device 1; a storage device 5 for storing the document being displayed in an editable format; and a storage device 5 for storing the structure of the document being displayed. a structure storage device 4 for storing and controlling these;
It is composed of a CPU 2 for making correspondence between the document being displayed and the document in the storage device 5.

Next, the operation of the document editing device as described above will be explained.

For example, assume that a horizontally written document as shown in FIG. 3 is displayed. It is assumed that paragraph 1 and paragraph 2 are different in character size, character spacing, and line spacing. It is assumed that this document is stored in the structure storage device 4 as shown in FIG. 4, for example. It is shown that the stage N1 starts on the display device 1 from the coordinate value y110. Furthermore, paragraph 1 is shown to be located at address R1 in storage device 5. Also, paragraph 1
It is assumed that each line is specified by the half-width, etc., modification information 11 (the shaded area in FIG. 4) on a line-by-line basis and the at in the storage device 5 at the beginning of the line. Let the coordinates of this position be (X3, y3). The arithmetic device 2 refers to the contents of the structure recording device 4 (FIG. 4) and learns that the specified position is y1 included in paragraph 1, since y3<y2. At this time, information such as character size, character spacing, line spacing, etc. regarding paragraph 1 is obtained from the storage device 5 based on addresses R1 and R12. Next, calculate based on the information between the lines, and y
We know that the 3 coordinate corresponds to the 4th line of paragraph 1. The first address of the fourth line is r4, and it is known from the modification information that half-width control is continuing. This and
Based on the character size and character spacing information, the user knows that the x3 coordinate is the third character from the beginning of the fourth line, and can point to the character from the storage device 5. same'
Even when the characters in paragraph 2 are specified, the beginning of each line can be easily found by knowing the character size, character spacing, and line spacing.

[Effects of the Invention] As described above, according to the present invention, even documents containing multiple character sizes, character spacings, and line spacings can be easily pointed, and editing can be performed in a format similar to the printed format. The effect is great because it can be done.

Furthermore, even if there is a figure in the document as shown in FIG. 5, pointing can be easily performed by simply storing the beginning address of each line as in FIG. 4.

Furthermore, by storing characters such as titles and explanations in figures or sentences in tables in the same format as in FIG. 4, pointing can be performed in the same way as the characters in the sentences.

In the embodiment, information such as character size, character spacing, and line spacing is stored in the storage device 5, but in order to perform high-speed pointing, it is also possible to store the above information in the structure storage device 4. be. In the structure shown in FIG. 4, each line has modification information such as half-width, but if this modification information is added to each character in the storage device 5, the structure storage device 4, there is no need to have modification information. The structure in this case is, for example, as shown in FIG.

Further, although the first address of each line is given as an example, various other modifications are possible, such as a format in which the total number of bytes of character codes and control codes included in each line is held.

As described above, according to the present invention, it is possible to easily point a document including a plurality of character sizes, character spacings, and line spacings.
