Abstract

PURPOSE:To obtain a miniature device simplified in inspection process by providing the inspecting device consisting of a lighting device and three photodetection camers contained in a box as one body. CONSTITUTION:To inspect the inside surface of a can body by the titled device, the inside surface of the side wall of the can body rotating on can axis X-X is irradiated directly with light from lighting device 6 over the overall can-axial length and to a wide width about a half, for example, of the can diameter. Then, three photodetection cameras 7a, 7b and 7c their charged parts respectively. Then, a fault is discriminated by the conventional means and if a defective can is found, a signal is generated.
