Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a drawing input method that reads a fixed format drawing in which characters, symbols, etc. are written, and performs image processing, graphic processing, etc. This research relates to improving methods for converting text and symbol information on standard format drawings into coded information suitable for computer processing. BACKGROUND ART As an example of a fixed format drawing in which characters, symbols, etc. are written, drawing D as shown in FIG. 5 is assumed. This fixed format diagram D is divided into a plurality of lines by rules mF, and further divided into blocks B. This block B includes, for example, a symbol column, a comment column, and a sixth column.
Characters, symbols, etc., as shown in the figure, are entered by hand. The following method is generally used to convert such a completed drawing D in a fixed format into coded information that can be input and processed by a computer. That is, the standard format drawing D is read with an image scanner or the like to generate binary image data, and one line is cut out for each column, as shown in FIG. 7(a). As shown in (b) and (c),
Image display area A set on the CRTI display screen

- Manually key the keys in area A2 one after another. Figure 7(a). Image display area A in (b) and (c)
1 is an area where the original image pattern read from drawing D is displayed, and data entry area A2 is
This is an area set at the bottom of the image display area A1 to display data entered from the keyboard.4 Now, FIG. The row rNDOAo 3J containing the symbol field in drawing D is displayed, and cursor C is set at the first digit of data entry area A2. In this state, the operator moves the image display area A1 as shown in FIG. 7(b).
While referring to the data entry area A2, enter the data corresponding to the specified position using the keyboard. FIG. 7(c) shows this block of interest rNDO
The data input process for Ao3 J has been completed. According to such a processing method, there is no need to look at the original drawing D after reading the drawing D with an image scanner;
All you have to do is refer to the RT display screen and input the keys manually.
It is easy to operate, and the burden on the operator is lighter compared to manually typing the appropriate characters and symbols while looking at a drawing. Problems to be Solved by the Invention> However, in the above-mentioned system, in order to reduce the trouble of drawings by the designer, part of a character symbol string is Drawing D, which has been omitted, cannot be processed properly. That is, in the image display area A1 on the e R 'l' display screen, the original image pattern "△IIΔII△3" is displayed, for example as shown in FIG.
II J is a repetition symbol) is displayed, so the operator does not know what key to enter in the data entry area A2 based on the information only in the image display area A1.

Therefore, looking at the original drawing D in FIG. 8, the repetition symbol r
) Since it is necessary to check the characters and symbols corresponding to I J each time when pressing the keys manually, there is a problem that the operation is complicated and it is easy to make manual key mistakes. The present invention aims to solve such problems, and even if a part of a character or symbol string is omitted due to a repeated symbol, the character symbol in the drawing including this omitted part The purpose is to provide a method for efficiently converting the entire information into coded information. Means for Solving the Problems> The present invention, which has solved the above problems, comprises an image scanner that reads a drawing and outputs a binary-converted image signal, and an image memory that stores this image signal as 21 image data. , a CRT for displaying various information, a keyboard for inputting characters and symbols, and M for cutting out graphical elements in each block in the standard format drawing from the binary image data and controlling signal exchange between the respective parts. Equipped with J Gobe,
Code for a standard format drawing that is divided into multiple line blocks by ruled lines, and if the content of each block in the current line is partially the same as the content of the corresponding block in the previous line, a repeat symbol is written in the block. In the drawing input method for obtaining data, on the display screen of the CRT, an image display area for displaying an image pattern of graphic elements in the block of interest, and data for inputting data corresponding to this image pattern from a keyboard.・Set the entry area and the data area where the data entry result of this block of interest is transferred and displayed after data input processing,
If the repetition symbol is in the image display area corresponding to the block of interest in the current row, input data corresponding to the repetition symbol from the keyboard by referring to the data entry result displayed in the data area. This drawing input method is characterized by:

Effects> In the drawing input method of the present invention, the content of the already processed block in the line preceding the block of interest in the current line is displayed in the data area, the block of interest in the current line is displayed in the image display area, and the block of interest in the current line is displayed in the image display area. If there is a repeat symbol inside, input the data into the data entry area while referring to the data area. Embodiments> FIG. 1 is a schematic configuration diagram of a drawing input device according to the drawing input method of the present invention. In this figure, a fixed format image D is scanned by an image scanner 2, and the read drawing information is converted into a binary value and stored in an image memory 3 as drawing information. In the image memory 3, corresponding to drawing D, the graphic part has pixel values "
1", and the background part temporarily stores binary image data with a pixel value of "0". The control unit 4 is implemented by a microprocessor, etc., and performs overall control, and also displays a preset standard drawing. Based on the format information, the graphical elements of each block are cut out for each column on the drawing from the binary image data stored in the image memory 3, and the cutout results are sent to the CRTI. , symbols, etc., and the control unit 4 receives manually entered data using keys.
Send to RTI. The CRTI displays various information, such as the graphical elements of each block, ie, the original image pattern, and key manual results. Disk 6 stores converted code data of image patterns such as characters and symbols. Furthermore, in the method of the present invention, as shown in FIG. 2, an image display area A1 and a data entry area A2 are set on the CRTI display screen in the same manner as in the conventional CR'V display screen,
Furthermore, a data area AO is set above the image display area A1 in which the result after data entry processing is copied and displayed in the data entry area A2. Next, a drawing input method of the present invention using the drawing input device configured as above will be explained. In addition, the fixed format drawing D to be read is indicated by the repetition symbol "r II" as shown in FIG.
Let us refer to drawing D in which some characters and symbol strings are omitted. First, a drawing D to be read is loaded into the apparatus shown in FIG. 1, and the control section 4 activates the image scanner 2 to complete reading.

The image scanner 2 scans the set drawing D,
The image signal is stored in the image memory 3 as binary image data. The control unit 4 starts cutting out graphical elements of each block on the drawing D from the binary image data stored in the image memory 3 based on drawing format information set in advance. Furthermore, the control unit 4 instructs to display the cutout result, that is, the image pattern of the bronc of interest, in the image display area A1 of the CRTI.

The display state at this point is shown in FIG. 3(a).

In Figure 3 (a>, the character string "%SWO O" in the first block in drawing D is displayed in the image display area A1.
The original image data of IJ is displayed. At the same time, a cursor (

The operator selects the original image pattern "%SWO 0 1" of the block of interest displayed in the image display area A1.
While looking at J, input the corresponding characters and symbol data in sequence from the keyboard 5 to the position of cursor C in data entry area A2. The key human power situation is shown in Figure 3 (b). At this time, the control unit 4 sequentially moves the cursor C so that the image pattern and the data entry result are displayed in correspondence. Next, as shown in Figure M3 (c), the corresponding block's !
When the operator inputs the data “1” after “I” and the control unit 4 detects that the data entry of this block is completed, for example, after the data “1” after “I&”, a carriage return, etc. is input from the keyboard 5. When it detects that it has been entered, the data entry result “%SWO Q I
Copy J so that it is displayed in data area AO. Next, as shown in FIG. 3(d), the data entry l-
The results are displayed in the data area AO, and the image pattern of the next bronc to be processed with characters and symbols written in it is displayed in the image display area A1. That is, the data input processing result "%SWOOIJ" is displayed in the data area AO, and the image display area A
"△II△Δ△2" is displayed in O (however, r 11 J is a repetition symbol and △ is a blank). Note that if the block of interest is the first block, there is no previous block of interest. , as shown in FIGS. 3(a) to (C), ρ■ is not displayed in the data area AO that displays the data entry result of the previous block. On the other hand, the control unit 4 displays the data entry result of the block of interest displayed in the data area AO, “%SWO O I
J is stored on disk 6 as converted code data. Now, as shown in the display screen of FIG. 3(d), the repetition symbol "r II" is displayed in the image display area A1 of the block of interest.

Figure 3<e) shows this key human power situation. Here, the repetition symbol r I)' corresponds to F%3w
It turns out to be oOJ. Next, the operator is the third
As shown in Figure (f), data ``2'' corresponding to the image pattern ``2'' after 1& of the image display area AO of the block of interest is manually entered. From now on, the operator performs the same operation, and the letter in drawing D,
Convert all symbolic information into coded information. In addition, processing examples when there are multiple repetition symbols r II J in the block of interest are shown in Fig. 4 (a), (b), (c), (
Shown in d). Even in this processing example, the basic processing operations are exactly the same as those shown in FIGS. 3(a) to 3(f). In addition, in the above example, an example was shown in which "〃" is used as a repetition symbol, but this is not the only symbol, and any symbol can be used as long as it instructs to repeat the contents of the previous line or block. As described above, the drawing input method of the present invention allows blocks in which characters and symbols are written in a standard format drawing to be set to the same image pattern (image display area A1) that corresponds to the current block of interest. The data entry result of the key input corresponding to the image pattern of the block of interest (data entry area A2>) and the converted data of the previous block of interest (data area AO) are displayed in correspondence. .Then, each time the data input process (key human power) for the current block of interest is completed, the data entry result (data entry area) of the current block of interest is replaced with the converted data of the previous block of interest. Displayed data area (AO
), and the image pattern of the block to be processed next is displayed in the image display area (A1). Effects of the Invention> According to the drawing input method of the present invention, the following effects can be obtained. (1) Even if there is a repeated symbol when filling in a standard format drawing, you can easily find the key of the corresponding character symbol data by simply looking at the image display area (A1) and data area (AO) on the CRT without referring to the original drawing. It can be easily done manually. f2) Image display area (A1) on the CRT display screen
, the data entry area (A2), and the data area (AO) are displayed in correspondence, so it is easy to check the input operation at the same time as the manual input of the keys. (3) The image display area (A1) displays only the image pattern of the block of interest in which characters and notes are written in the standard formant drawing, so the image pattern of all blocks is displayed. The key human labor time can be reduced compared to when processing is done all at once.
