Description

Detailed Description of the Invention (a) Technical Field of the Invention The present invention relates to an improvement in a method for inputting characters between figures in a data input/output device configured by combining a central control unit with a display and a digitizer. As a data input/output means in a data processing system, it directly appeals to the operator's sense of sight to display figures and characters on a display or other screen.
B) and a method of creating data by performing interactive operations via input means such as a light pen are used. This image input/output means uses a central control unit (cp
U) Although it has weaknesses such as increased control load and storage capacity, and limitations on the amount of data on the display screen, it is based on real-time technology that matches the advanced data processing ability of the CPU with the comprehensive judgment ability of humans. It is easy to handle data by displaying, modifying, deleting, transferring, etc. two figures and characters through a close interaction format, and the data of a plurality of correlated figures φ characters can be displayed as an image on the display screen, and its contents can be easily handled. It has become widely used in applied fields such as CAD, data management, and simulation by taking advantage of the fact that operators can process it in parallel. (e) Conventional technology and problems In the method, following the input and display of the figure that usually takes priority, the symbol and explanatory characters (hereinafter referred to as characters) of the figure are specified in the remaining blank space of the displayed figure.
Normally, the characters are inserted by arranging them in a fixed direction of X or Y. However, when inserting characters, the operator refers to the display screen for each unit of characters and inserts a star shape at a position close to the shape. There is the inconvenience of having to confirm that there is no contact with or duplication.

(d) Purpose of the Invention The present invention eliminates the troublesomeness of the above-mentioned character insertion operation, detects the presence or absence of a figure and the margin required for the outer periphery of the figure, and inputs characters in units of character strings arranged horizontally or vertically. , which attempts to provide an easy-to-use and highly efficient character insertion method by automatically performing character arrangement processing by expanding the character pitch to include margin dimensions when a contact or duplication occurs in the middle of a character string. .

(e) Structure of the Invention The object of the present invention is to provide a data input/output device comprising a central control unit, a display means, a digitizer, an input means such as a keyboard, etc.; The central control unit shall not be equipped with a storage area to register and hold the included figure projection area data, character data such as character size, character arrangement pitch, and font inclination depending on the type of character, and figure and its name data. The character strings to be inserted and arranged in the space of the figure projection area obtained by accessing each data in the storage area are temporarily stored in another storage area, and the first character position of the character string is set as the reference. At the same time, the following characters are inserted and arranged by adding the coordinates of one character pitch at a time in the direction of the character string, and a surrounding space is set for each character in the character array projection area with the area as the center, and in that space area, the above-mentioned figure is Check the projection area and the preceding character array projection area, and if a duplication occurs, move the array projection area of the subsequent input character across the figure projection area in the array direction to create a character string without overlapping each other. This can be achieved by providing a method for manually inserting characters into graphic data, which is characterized by inserting and arranging characters.

(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 its processing procedure.

In the figure, 1 is a central control unit (CPU), 2 is a storage unit,
3a is a graphic display, 3b is a digitizer, 4a is a character display, and 4b is a keyboard. Furthermore, in the storage area of the storage unit 2, 21 is a character insertion control program, 22 is figure projection area data including the peripheral spacing of the figure, and 23 is the character size 2 for each type of character.Character arrangement pinch, font inclination, etc. 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 CPUI stores graphic data inputted by the digitizer 3b in the storage area 22 of the storage section 2 and displays it on the screen of the display 3a. Although the registered figures are not shown, the CPU''' accesses the registered figure data in the storage area 24 by specifying the menu sheet corresponding to the preset data or by specifying the shift flag by inputting the KB3d. Input operation of figure data may be performed in place of drawing and input operation.For the input/output of figure data, data regarding the actual figure is manipulated, but the subsequent handling of figures according to the character insertion control program 21 is the same. In order to maintain the spacing between the figure and the characters around the outer shape, the specified peripheral spacing dimensions such as Q, l
It is assumed that the figure projection area includes mm. In step 2, the character data table 23 is selected using the digitizer 3b or KB3d to designate the type of character. For example, if you specify Kaku Gothic with 002, the character height will be 2, the character width will be 09, with no slant, and if you specify Shiitalic with Koryo♀, the character height will be 21111, and the character width will be 0.
A slant angle of 200 (right diagonal) for a 9 mm font is obtained. The dimensions of this, etc. are not the font lines, but the letters are this 2X0.
9 rectangle or a 2 x 0.9 parallelogram with an inclination of 20 degrees.Hereafter, the projection area of a character refers to the quadrilateral that shows this outer shape, regardless of the character shape specific to the individual character.

In step 3, a figure into which a character string is to be inserted is designated on the screen of the display 3a with a cursor. In step 4, the CPU 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 insertion character string table 25.

The inserted character string table 25 is retained while the inserting operation of the character string continues, and the inserted character string table 25 is temporarily held when the inserting operation ends and the transition operation to the next cycle is performed to insert the character string of the next figure name. Memory contents will be reset.

If there is no corresponding character string in the registered graphic data table 24, multiple input operations are performed using the KB3d to select characters one by one from the character data table 23 via the CPUI and store them in the inserted character table 25. In step 5, set the starting coordinate position of the inserted character string, for example, the lower left corner of the rectangular character distribution area of the first character, the height of the first character x 0.9 mm, and the reference point P on the digitizer 3bX or KB3d. In step 6, which involves a lot of input, first the coordinate position of the character projection area of the first character is determined. In step 7, parallel enlargement is performed in the upper, lower, left, and right directions around the character array projection area so that, for example, in the case of a printed wiring board, the height of the 2-pitch grid range is 5.
．． Space area S of 08 tomo x width 2.54 art. and set
Limiting this range, overlap in the graphic projection area or the character array projection area to be described later is checked. In this way, there is no need to check with all the figure projection area data 22.
Since it is only necessary to check for overlap in a very limited range, the overlap check can be confirmed in a short time.The presence or absence of overlap refers to the overlap between both projection areas, regardless of the solid line of the figure or character.

If there is no overlap in step 8, in step 9 the next character is added along the character arrangement by the character pitch l pitch, for example, if it is the second character in the horizontal arrangement, it is moved only to the X value of the previous first character position coordinate. Add the character pitch values obtained in step 2 to obtain the second character.

Let it be the coordinate position. Steps 6 to 1o are repeated until the character string ends in step 1o. If there is an overlap in step 8, the CPU moves the figure projection area in the direction of the character string according to step 8-1, and then repeats the process in step 6.
~ 1o many treatments.

When the end is obtained in step 10, the character string is inserted into the space of the graphic projection area in step 11, and the result is displayed on the display 3a for confirmation. In this way, the figure projection area is set in advance to include a certain interval dimension around the outer periphery of the figure, and the solid line of the character font falls within the character array projection area, so the interval between the projection areas is set to at least 0 initially. A constant preliminary interval value, for example 0.1 interval, is maintained. Next, if there is a character string inserted in advance in step 12, the spatial area S of the preceding character string, that is, the area S of, for example, height 5.081EIX and width 2.5411I centered on the character array projection area for each character, is inserted next. Similarly, in Step 6 of the inserted character string, the projection area for each character, for example, height 2 mm x width 0.91 K, is checked for overlap in the spatial area S. If there is no duplication in step 13, and if the insertion operation of the character string can be confirmed in step 14, the character insertion arrangement is completed. If there is an overlap in step 13, the starting coordinate position of the character string is reset again in step 5, and the subsequent steps are repeated. The above description assumes that the character strings are arranged horizontally 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.

(b)) As described in detail, 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 each time the operator inputs each character. A character string can be easily inserted into a space of a figure without the trouble of checking that there is no contact or overlap between the figure and the character line at the position where the figure is inserted.
