PURPOSE:To reduce greatly the time for extraction of the parts allotment information and at the same time avoid the mistakes, by extracting the necessary information by the pattern processing based on the result obtained by allotting the parts or the dummy parts onto the surface of the prescribed region. CONSTITUTION:The pattern information 12 or the size information 13 of the name of parts are stored onto the register data memory 10 and regarding the IC chip to be provided on the printed circuit board. Then the information 12 and 13 are supplied to the parts name matching process parts 14-0-14-n and the size matching process parts 15-0-15-n respectively. On the other hand, the digitized pattern information of the picture memory 9 and supplied from the pattern digitization process part 5 is read out and then applied to the process parts 14-0-14-n as well as 15-0-15-n to receive a checking for the matching state. And for instance, if both the process parts 14-0 and 15-0 detect the matching signals simultaneously, the coordinate position (X0, Y0, name of parts, angle) is extracted for the corresponding IC chip. |
