ABSTRACT:
Objects to be inspected are transferred successively in one direction on a conveyor and irradiated by a light source and photosensed by a single optical image sensor only, such as a video camera. The optical image sensor is so arranged that it simultaneously photosenses a plurality of the successively transferred inspected objects, and the conveyor is so constructed that during the period in which the objects pass through the visual field of the optical image sensor, the objects are rotated so that their entire round inspected surfaces are all respectively photosensed by the optical image sensor. The video signal from the optical sensor is supplied to an inspection device which periodically samples the video signal in synchronization with the shift movements of the objects, and judgment signals therefrom are respectively supplied to the parallel input terminals of a shift register, the number of which is the same as that of the number of objects in the visual field and at the same time a shift pulse synchronized with the movement of the objects is supplied to the shift register whereby it produces an output signal corresponding to the defective object to cause rejection of the defective object.
