SYSTEM FOR INSPECTING AN APPARATUS OF A PRINTED CIRCUIT BOARD

A motion of a printed circuit board (1) is detected by an encoder (4) arranged aside a belt conveyer (2), and the encoder generates a detection signal (S3) which activates a timing signal generator unit (5) for generating an image pickup start timing signal which is fed to a time measuring unit (6) for measuring the image storing time which corresponds to the time interval of the image pickup start signal (S1). According to the image storing time, the image signal (S2) generated by the line CCD camera (3) is normalized by the normalizing calculation means (7), and thereafter, the mounting condition of the printed circuit board is judged by the image recognizing section (B) with the use of the image data (D) to thereby realize a simple and convenient mechanism at a low cost and at a high precision.
