Abstract: PURPOSE:To automatically inspect a pritned circuit board by installing a polgonal cone type mirror which outputs the beam as it is to an opened port when the beam is supplied with the first amplitude and outputs the direction change beam which forms a prescribed angle with the beam through reflection, when the beam is supplied with the second amplitude. CONSTITUTION:The first separation beam B1 is scanned with the first amplitude W1 by a galvanometer 23A, and a bridge, solder etc., can be inspected as in the conventional manner. When the part where a mounted IC having the lead L of a J bend on a printed circuit board P to be inspected is inspected, the beam B is scanned with the second amplitude W21 W22 or W23 by the meter 23A, and at least the first separation beam B11 is radiated to the substrate P. Accordingly, when the lead L is soldered, the beam B11 is reflected by a soldered part HJ, and if the lead L is not soldered, the beam B11 is not reflected, and the bridge, solder wetting, etc., can be detected by ther total light receiving quantity received by the light receiving element of a light receiving part 13.
