Description

Description: (a) Technical Field of the Invention The present invention relates to an improvement in an inter-graphic character input device in a data input / output device configured by combining a display and a digitizer in a central controller.

(B) Background of the technology Recently, as a data input / output means in a data processing system, a figure or a character is displayed on the screen of a display or the like by directly appealing to the visual sense of an operator, a digitizer, a keyboard (K
B) and a method of creating data by performing an interactive operation via an input means such as a light pen. This image input / output means uses a central control unit (CP
Although it has weaknesses such as an increase in load and storage capacity in U) control, or limitation of the amount of data on the display screen, real-time matching of the high data processing capacity of the CPU with the total judgment of human The data can be handled easily by displaying, modifying, deleting and transferring figures, characters, etc. by a close interactive form, and a plurality of correlated figure and character data are displayed as images on the screen of the display, and the contents are displayed. Taking advantage of the fact that operators can process in parallel, it has come to be widely used in application fields such as CAD, data management and simulation.

(C) Conventional Technology and Problems Conventionally, in the above-mentioned image input / output means, subsequent to the input display of the figure that normally has priority, the code or explanatory character (hereinafter referred to as a character) of the figure specified in the remaining blank portion (space) of the displayed figure.
Are usually arranged in a fixed direction of X or Y and inserted, but in the character insertion work, the operator refers to the display screen of the display every input operation of each character and at the position close to the figure and There is an annoyance that requires confirmation that there is no contact or duplication.

(D) Object of the Invention The present invention eliminates the troublesomeness in the above character insertion operation, detects the presence or absence of a figure, and detects a margin dimension required around the figure, and performs character input in a character string unit in a horizontal or vertical arrangement. When contact or duplication occurs in the middle of a character string, it is intended to provide a highly efficient character insertion device with operability by automatically performing character arrangement processing by character pitch expansion including margin dimensions. .

(E) Structure of the invention The object of the present invention is to arrange the central control unit with the display means on the display and the input means such as a digitizer and a keyboard, and to store the data for displaying the already input figures and characters. In the character / graphics data input / output device held in, when determining the arrangement position of each character of the character string so as to arrange the specified character string in the specified direction with the specified display position as one end, the storage As data to be stored in the section, a figure projection area indicating the range of the area on the display including the space to be provided around each figure,
The central control unit also holds data of a character array projection area indicating a range of a quadrilateral area indicating the outer shape of the character,
The first character position from one end of the specified character string is set to the specified display position, and subsequent characters are sequentially arranged in the specified character string direction by adding coordinates by one character pitch. In the case of an array, the character array projection area of the character is determined based on the array position of the character, and an inspection area having a certain width is set vertically and horizontally centering on the character array projection area, and the range of the inspection area is set. Check the overlap between the character array projection area and the figure projection area and the character array projection area of the data of the already input graphics and characters held in the storage unit, and if there is an overlap, the array position of the character Are arranged so as to be moved in the arranging direction to the position where the overlap disappears. This can be achieved by providing a character insertion device.

(F) Embodiment of the Invention An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a character insertion method according to an embodiment of the present invention, and FIG. 2 is a flowchart showing the processing procedure.

In the figure, 1 is a central control unit (CPU), 2 is a storage unit, and 3a
Is a graphic display, 3b is a digitizer, 3c is a character display, and 3d is a keyboard. Further, in the storage area of the storage unit 21, 21 is a character insertion control program, 22 is graphic projection area data including the peripheral distance dimension of the graphic, and 23 is character size, character array pitch, font inclination, etc. for each character type. A character data table holding the stroke patterns corresponding to the parameters, 24 is a data table of registered figures and their names, and 25 is an area for temporarily storing character strings to be inserted and arranged in the space of the figure projection area for each operation unit. .

The CPU 1 performs character insertion processing according to the control program 21.

In step 1, the CPU 1 stores the graphic data input by the digitizer 3b in the storage area 22 of the storage unit 2 and displays it on the screen of the display 3a. Although the registered figure is not shown in the figure, the CPU1 accesses the registered figure data in the storage area 24 by specifying a flag by specifying a menu sheet corresponding to preset data or by inputting KB3d, and the digitizer
Graphic data input operation may be performed instead of drawing and input operation on 3b. For input / output of graphic data, the data for the actual graphic is manipulated. However, in the subsequent handling of the graphic according to the character insertion control program 24, since the space between the graphic and the character is taken around the outer shape, a specified peripheral interval dimension, for example, It shall be performed by the figure projection area including 0.1 mm. In step 2, digitizer 3b or KB3d
The character type is selected by selecting from the character data table 23. For example, if you specify angular gothic with 002, the character height is 2 mm and the character width is 0.9 mm, and there is no inclination of the font. If italic is specified with 202, the character height is 2 mm and the character width is 0.9 mm. Is obtained. Here, these dimensions are not font lines, but the character is this 2 × 0.9 rectangle or 2 ×
It shows that it fits in a parallelogram with a gradient of 20 °, and the projection area of a character refers to a quadrangle that shows this outer shape regardless of the shape peculiar to an individual character. In step 3, the figure in which the character string is to be inserted is designated by the cursor on the screen of the display 3a. In step 4, the CPU 1 accesses the registered graphic data table 24 in the storage area to obtain a character string for displaying the graphic, and temporarily stores it in the storage area inserted character string table 25. The insertion character string table 25 is retained while the insertion operation of the character string continues, and the insertion character string table 25 is temporarily stored at the time of the transition operation to the next cycle for inserting the character string of the next figure name after the insertion operation is completed. The contents are reset.

If there is no corresponding character string in the registered figure data table 24, an input operation is performed from the KB3d to select one character by one character from the character data table 23 via the CPU 1 and store it in the inserted character table 25. In step 5, the leading coordinate position of the inserted character string is digitized with the reference point P at the lower left corner of the rectangular character projection area, for example, the preceding character height 2 mm × width 0.9 mm of the first character.
Input by 3b or KB3d. In step 6, first, the coordinate position of the character projection area of the first character is determined. In step 7, 1 or 2 if the printed wiring board is expanded by parallel expansion in the vertical and horizontal directions around the character array projection area.
A space area (inspection area) S having a height of 5.08 mm and a width of 2.54 mm in the pitch grid area is set, and the overlap in the figure projection area or the character array projection area described later is checked only within this area. In this way, the duplication check can be confirmed in a short time because it is only necessary to check the duplication within a very limited range without collating with all the figure projection area data 22. The presence / absence of this overlap indicates the overlap of both projection areas regardless of the solid line of the figure or character. If there is no overlap in step 8, the next character is moved along the character array by one pitch in step 9; The character pitch values obtained in step 2 are added to obtain the coordinate position of the second character. Steps 6 to 10 are repeated until the character string is completed in step 10. If there is an overlap in step 8, the CPU 1 moves in the character string direction across the figure projection area in accordance with step 8-1 and again performs steps 6 to 10. When the end is obtained in step 10, the result inserted in the space of the figure projection area of the character string in step 11 is displayed on the display 3a.
Display and confirm. In this way, the figure projection area is set in advance including a certain distance dimension on the outer periphery of the figure, and the solid line of the character body is included in the character array projection area. A certain preparatory spacing value, for example 0.1 mm, is retained. Next, in step 12, if there is a character string inserted in advance, the space area S of the preceding character string, that is, the height centering on the character array projection area for each character, for example, 5.
For the space area S of the character string which is inserted subsequently for the area S of 08 mm × width 2.54 mm, the overlap area is checked for the projection area for each character in the same space area S, for example, height 2 mm × width 0.9 mm. If there is no duplication in step 13, if the insertion operation of the character string can be confirmed in step 14, the character insertion sequence ends.
If overlapping occurs in step 13, the starting coordinate position of the character string is reset again from step 5 and the subsequent steps are repeated.
In the above, the direction of the character string is assumed to be horizontal arrangement on the X-axis from left to right, but it goes without saying that characters can be inserted in the same manner in the vertical Y direction as well.

FIG. 3 is a diagram showing an example of a character insertion arrangement. In the figure, squares and circles are figures of land and vias that have already been input, and double-dashed lines on the outside indicate projection areas of the figures.
The outline characters A to E indicate characters to be input with the point P as a base point, and the double-dashed line circumscribing them indicates the character projection area. A, B, C, and D were arranged at a predetermined character pitch, and there was no overlap with the already-entered figure projection area and character array projection area. However, E was detected as overlapping with the circle projection area, and crossed over this. It has been arranged. An outline character F in the lower left part of the figure and an area S surrounded by a broken line are an inspection area set as a range to be checked when the character F is to be input next time and the overlapping area of the figure and the character projection area. Indicates S.

(G) Effect of the Invention As described above, according to the present invention, in the conventional character insertion work, the operator approaches the figure by referring to the display screen of the display 3a every time the input operation is performed for each character. It is possible to easily insert a character string into the space of a figure without the troublesomeness of checking that there is no contact or duplication between the figure and the character line at the position.
