ABSTRACT:
Image data of lead terminals and a chip element provided on a circuit board are stored on a video memory. Part of the video data stored in the video memory is read out and stored in a RAM by a microprocessor to be compared with reference pattern data stored in an external memory. The position of the chip element is checked in this way by having reference to the lead terminals.
