FIG. 2 shows the overall configuration of the control program creation system 11 of the present invention. A display device 111 such as a CRT that displays required messages, control programs, etc., an input device 113 consisting of an input mechanism (tablet, mouse, etc.) for inputting data with various menus and a keyboard, and control programs and form CAD data. An external media device 11 such as a floppy disk device for reading the control program and writing the control program, a printer device 115 for printing out the control program on paper, and the control program and form CA.
It consists of a communication device 116 for outputting the data of D using a communication line, and a computer system 112 that connects and processes the above-mentioned devices. Note that the computer system 112 is operated by software.

In such a configuration, the processing in the system of the present invention will be explained with reference to the system flowchart shown in FIG.

When the system is started by operating the keyboard provided on the input device 113 (step 5100), a work menu as shown in FIG. 4 is displayed on the display device 111 (step 5101), so the operator can use the input device °' l of the work menu from the keyboard of 113

is selected and input (step 5102).

Here, for example, if "3) End" is selected by key input (step 5113), the system is ended. Also, if you select 】) Create a new pa using the key input (
Step 5103) is to send the form CA to the external media device 114.
The medium storing the form data created by the D system 1 is set, and the form data is read into the computer system 112 (step 5104). Based on the form data, the computer system 112 determines the form dimensions necessary for creating a control program and the positional coordinates of the character frame of the characters to be read.

Analyzes and collects information such as frame height, width dimension, frame feed pitch, and number of frames, and automatically generates a control program (
Step 5105). However, as described above, it is not possible to generate all the data necessary for creating a control program using only the data read by the form CAD system 1. In order to create a control program, you must also specify the size of the form to be read by the optical reader 6, the type of paper (paper for the optical reader or paper copied by a copying machine, etc.), and character type (kana). (letters, alphabets, numbers, kanji, symbols, etc.), the type of writing instrument entered in the reading column of the form (ballpoint pen, pencil, typeface, etc.), the designation of the output medium for the scanned data, and the file layout, etc. are required. .

Supplementary information necessary for creating these control programs is input into the computer system 112 in a screen interactive manner using the display device 1111 and the input device 113 (step 510).

If there is a difference between the control program generated last time and the control program generated this time, this fact is displayed on the display device Ill to notify the operator during the correction in step 5l12.

The operator considers the displayed discrepancies and performs correction work.

The control program newly created or modified in this way is
It can be output to a medium such as the floppy disk 13 or MT 15 set in the external media device 114, or it can be output to the control program paper 5 by the printer device 115, or it can be output to an optical reader online via the communication device 116. 6 or directly to the optical reading unit 6.

The control program created in this way is read into the optical reader 6 online or offline. Under the control of this control program, the optical reading device 6 reads the form and performs the necessary processing to read the read data 8.
is output.

In the present invention, furthermore, based on the form CAD data 2 created by the form CAD system 1, the position information of the character frame read by OCR as shown in FIGS. I try to get it through the system.

That is, as shown in FIG. 5, supplementary information such as the name of the OCR league to be read and the reference point of the reading device is input to the form CAD data 2 (step 5200), and as a result, the information shown in FIGS. 6 to 9 is input. Consider the unit system of output data, etc. Figure 6 shows that the unit system differs depending on the type of OCR reader (A, It) even if it is made by the same manufacturer, and Figure 7 shows that the reference side is different for each OCR reader, such as left reference and right reference. It shows. Further, FIG. 8 shows that the calculated dimension value differs depending on the presence or absence of the line mark 30. The same figure (A) shows that there is a line mark 30, and in this case, the dimension value varies from the end of the line mark 30 to the OCR character frame 32, and the same figure (B)
is the case where there is no line mark 30, and the form side 31 and OCR
This shows that the character frame 32 and the dimension values are different.

Furthermore, the origin of the form CAD and the origin of the read form may be different, so the form read by OCR League is the original form CAD.
Sometimes a part of the image is cut out and used, and in such a case the origin will be different. Figure 9 shows the original form 40 designed using form CAD, as shown in the questionnaire.
A part of the form 40 is cut out along the Kiritori line, and the number 44 of the cut form 42 is 0C1 (this shows the case where it is not read by a reader. In this case, the origin of the original form 40 is 41, and the number 44 is not read by a reader. The origin of the form 42 is 43, and it is necessary to correct the origin position.After inputting the supplementary information as described above, proceed to step 520 to extract OCR character frame data using the form CAD data 2, as shown in FIG. ~As shown in Figure 9, since the reference sides and unit systems are different, the unit system of the data is converted based on the input OCR reader name (step 520).
2) After that, a form/coordinate sheet as shown in FIGS. 10 and 11 is output (step 5203), and the system engineer codes a control program for the optical reading device (step 5204). 10th
The figure shows how the form design and the item number of the read field are outputted by an XY plotter, etc., and FIG. 11 shows how the coordinate values of each readout item are outputted by a printer etc. Information obtained from form CAD data includes OCR character frame position, image reading frame position, OC
There is an R-point circle position, and the printer (XY plotter) of the present invention outputs the item number (°"O1 to oa") of the reading field as shown in FIG. 10 along with the form design. This corresponds to the item number in Figure 11. For example, the coordinate value of the deposit amount field of item number 5 has a Y coordinate of "700".
”, the XIu mark is “500”, and the number of characters is 6.

Effects of the Invention: As described above, according to the present invention, the work of creating a control program, which was conventionally complicated, can be easily created by trial and error using a screen interaction method, thereby streamlining the creation of a control program. Another advantage is that there is no need for a conventional reading test to check whether coding is done correctly, and it is possible to deal with the unit system of output data.
