Next, the operation of the present embodiment will be described in detail with reference to the flowcharts of FIGS.

First, FIG.
Then, aperture data having a data structure divided into a header portion and a data portion as shown in FIG. 3C is read (step S1). The first comparison unit 3 compares and analyzes the pattern of the header portion of the aperture data with the pattern of the header portion of the header storage unit 8 read by the header reading unit 2, and determines the CAD type.

The data of the first row of the read aperture data is read out and stored in the comparison data array.
The data of the first row of the header data of the CAD maker stored in the header storage unit 8 is read, and the CAD maker of the matched header data is extracted. If the data of the first row of the header data of the CAD maker stored in the header storage section 8 does not match, the data of the next row of the read aperture data is read, and there is matching data. Or compare.

The CA stored in the header storage unit 8
The data on the first line of the header data of the D maker is
If the data matches the read aperture data, the data of the second row of the header data of the CAD maker stored in the header storage section 8 is read out next, and the next row of the previously extracted aperture data is read out. Then, a CAD maker name whose data in the second line of the header data of the CAD maker matches is extracted. Similarly in the third and subsequent rows, the aperture data is compared with the header data for each row.

If the data of the header part of a certain CAD maker matches all the data of the header part of the aperture data, the following processing is performed (step S2).

The second comparing section 5 compares and searches the data structure (D code, shape, size) of the data portion of the aperture data. That is, the format description portion of the data portion stored in the data portion storage portion 9 for the extracted CAD maker is read out, and is compared with the format description portion of the data portion of the aperture data. If the format description format of the data part matches, the data is read in the format of the shape part and the following processing is performed. First, from the data of the data portion of the aperture data, the character string of the item describing the D code in the format obtained in the previous processing is read. Normally, the D code is D1
Since 0 to D999 are used, the character string is searched. Next, in order to search for a shape part, a comparison analysis is performed with the pattern of the shape part in the data part storage part 9 read by the data part reading part 4 to determine whether there is a character string of the corresponding shape. The data size is composed of a sequence of numbers. The three types of data are compared and searched to determine the type of the data (step S3).

The extracting unit 6 extracts necessary D code numbers, shapes, and sizes according to the format of the pattern-matched data (step S4).

The conversion unit 7 manufactures the shape and size of the D code corresponding to the data extracted by the extraction unit 6 with respect to the D code of the Gerber data (step S5) read from the second input unit 11. At the same time as conversion into data, it is allocated (step S6).

If the pattern does not match the pattern in the header section storage section 8 and the data section storage section 9, a message indicating that there is no pattern match is displayed on the output section 10, and
The data of the header part of the aperture data and the data of the data part are output to the output unit 10 (Step S
7). Then, a menu for designating the D code item, the shape item, and the size item is displayed. The operation command input means receives a command to select a data item in the format description portion by operating the mouse or keyboard of the operator. An instruction to specify the item, the shape item, or the size item is received and stored. Next, a shape table is displayed, and the operation command input means receives a command for selecting a new shape character string for the D code in the data line of each data portion by operating the mouse or keyboard of the operator, and inputs the new shape character string and the shape. A shape table describing the type is stored. The header section of the aperture data is stored in the header section storage section 8, and the format description section of the data section is stored in the data section storage section 9. The selected shape character string is stored in the shape character string list. By storing in this way, the data of the same format matches the pattern thereafter in the data part pattern comparison processing, and the shape of the D code is assigned (step S8).

If the pattern does not match,
By inputting the shape and size for the D code,
Can be assigned during conversion.

Next, the operation of this embodiment will be described using a specific example. As shown in FIG. 3, for example, the header storage unit 8 stores 12 in FIG. 3A, 14 in FIG.
A pattern of a header portion of various CADs such as 16 in (c) is stored.

For example, assume that the aperture data shown in FIG.

The first comparing section 3 searches whether or not the pattern of the 12 headers shown in FIG. 3A exists in the header memory 8 (step S2). 1 in FIG.
If the pattern of the header portion of No. 2 is found to be the pattern of Company A, then it is compared whether or not the pattern of the data portion of 13 in FIG. 3A is composed of necessary data.

For example, the aperture data shown in FIG. 3A and the aperture data shown in FIG. 3B are created by the same CAD, and the header portion has the same pattern, but the data portion has a different pattern. The second
The data portion is searched by the comparing unit 5. When the first field is searched, both of FIG. 3 (a) and FIG.
Since the character string is 10, the first field is determined to be D-code data. When the second field is searched, FIG. 3A shows data of the numerical value of 0.1.
It is determined to be size data. FIG. 3B shows a character string of the CIR. In this case, the character string and the shape are compared and searched using a table as shown in FIG. Is determined. In this way, the data fields of the D code, size, and shape are searched, and the necessary data is extracted by the extraction unit 6 (step S4).

It is assumed that Gerber data as shown in FIG. 5 has been read from the second input unit 11 (step S5). The first line in FIG. 5 is a code for selecting a tool, and data following this line is converted into the size of the shape and size of the aperture designated by D10. The second to seventh lines are the coordinates of the actual data. The eighth line indicates the end of the data. The D code of the Gerber data read by the conversion unit 7 and the D code extracted by the extraction unit 6 are associated with each other, and when converted into data to be manufactured as shown in FIG. It is automatically assigned (step S6). FIG. 6 shows the converted manufacturing data. In the first and second lines, the names and dates given after the conversion are inserted. The third line is the D code, shape and size set after automatic conversion, and ALC010 indicates that the shape is CIRC
LE indicates that the size is 0.1. The fourth to ninth lines are the actual data coordinates, and the tenth line represents the end of the data. In this way, the conversion from Gerber data to manufacturing data is automatically performed.

[0039]

The first effect is that the type of the CAD of the aperture data can be determined only by storing the header part of the aperture data for each CAD. As a result, even if the format of the aperture data is not known, it can be automatically determined, and the conversion can be performed at high speed.

The reason is that the header format of the aperture data is formed in a predetermined format, and only the characteristic portion is stored in the storage section, so that only the characteristic header portion is stored. This is for comparison.

The second effect is that, by automatically extracting the D code number, shape, and size described in the aperture data, the data can be automatically converted, and input errors and the like can be reduced. .

The reason is that the input by hand is eliminated by associating the aperture data with the Gerber data as data.
