<p>PROBLEM TO BE SOLVED: To provide an imaging method of a liquid filling container and a device capable of imaging two or more kinds of states of a container surely and simultaneously when the liquid filling container is imaged. SOLUTION: In this method and device, plural pairs of imaging devices 2, 5, 8 comprising a pair of light emitting devices 3, 6, 9 and light receiving devices 4, 7, 10 are provided, and light from the light emitting devices 3, 6, 9 is irradiated to the liquid filling container B, and irradiated light is received by the light receiving devices 4, 7, 10, to thereby image the container B in each of the plural pairs of the imaging devices 2, 5, 8. In the plural pairs of the imaging devices 2, 5, 8, wavelengths of light irradiated from each light emitting device 3, 6, 9 and received by each light receiving device 4, 7, 10 are differentiated mutually.</p> |
