Abstract
PURPOSE: To enable the use of a conversion element quick in the response speed and detect light beam entering the inspection area by means of a plurality of reflection devices, a photoelectric convertor for receiving reflected light from the reflection devices and an electric circuit for producing the inspection start timing signal.
CONSTITUTION: A laser beam irradiated vertically viewed from the plane of the drawing depicts on the surface of a reflection device 20 a pattern identical to the scanning pattern depicted on the printed board. Optical conversion elements 21W24 which are all quicker in the response speed than silicones, photo-diodes and the like receive reflected light from the respecitve reflection surfaces 20-1W20-4. A condenser is provided between reflection surfaces corresponding to respective optical conversion elements. Adders 25 and 26 and a comparator 29 combine to generate an inspection start timing signal for the vertical scanning. With such an arrangement, it is possible to form the reflecting surface for the reflection device at a high accuracy thereby ensuring the accurate inspection start timing signals.
