ABSTRACT:
A moving object inspection system is disclosed in which a stroboscope radiation is made on an object to be inspected, the object is picked up by a television camera, a position detection device provides a position detection signal when the object arrives at a specified position, and an object inspection apparatus is provided. In this apparatus the period including before and after the horizontal synchronizing signal from the television camera is set as an inspection intermission period during which no inspection for the object is conducted, and the stroboscope radiation is carried out at the same timing as the position detection signal when the position detection signal arrives at the same time as the vertical synchronizing signal from the television camera, or at the beginning of the inspection intermission period immediately after the position detection signal when the position detection signal arrives at any other time than with the vertical synchronizing signal.
A moving object inspection system further sets an inspection inhibit period of the object immediately after the stroboscope radiation.
