Abstract
PURPOSE: To make it possible to accomplish the automatic inspections with the use of a simple construction by forming a slit pattern light on a print substrate to make the pattern detecting signals binary so that the existence of the parts may be judged.
CONSTITUTION: By the slit light from a slit light projector 6, a slit pattern 6 is formed on a substrate 1, and the reflected lights from the slit patterns according to the existence of the circuit parts 2a of the substrate 1 are received by a photoelectric converting element 8 having a number of subelements. These receives signals are converted into binary signals by a binary circuit 9, which is preset with a threshold value. A parts existence detecting circuit 10 judges that there are the parts 2a, when the number of low level bits is large in the binary signals, so that it memorizes the judged results in its memory. Then, an XY table 5 is controlled through a print substrate analyzing circuit 11 for memorizing the parts positions in the substrate so that similar judgements are repeated.
