Object inspection apparatus

摘要

The invention relates to an apparatus for photographing and inspecting the surface of objects such as tablets. A pair of conveyor belts guided by guide rails on opposite sides of a row of suction aperture formed at even spacing in a straight line on a guide plate covering an open face of a suction box, are driven and an object seated across the pair of conveyor belts is photographed while being conveyed to thereby inspect the surface of the object. The suction apertures are formed to a size such that peripheral rims thereof are outside of the diameter of a circle having a diameter of a gap between the pair of conveyor belts on opposite sides of the suction aperture row, and the length of a portion between adjacent suction apertures is set to less than a gap between the pair of conveyor belts. Fragments of the objects being inspected are quickly sucked away from the suction apertures into the suction box, thereby preventing being caught between the conveyor belts and in the suction apertures. Moreover, even if powder of the object becomes attached to the periphery of the suction aperture, it is not photographed so that photographing inspection errors are prevented.
