Abstract

PURPOSE: To detect a pattern accurately, by projecting lights to the printed circuit substrate from plural angles.
CONSTITUTION: Light sources 5 are installed left and right oblique directions for printed circuit substrate 3. Projection lights from these light sources 5 are projected to printed circuit substrate through lens 4. When a rugged pattern exists on printed circuit substrate 3, projection lights are reflected upward through this pattern. Lens 2 and TV camera 1 are provided in the advance direction of the reflection light, and the reflection light from the pattern is picked up by TV camera 1. Thus, reflection on the rugged side face becomes notable, and the pattern can be detected accurately.
