PURPOSE:To detect a disturbed egg optically, and to improve detection speed, by irradiating the white with ultraviolet rays, detecting fluorescence emitted from the yellow by a receptor element, deciding as to whether the detected egg is a disturbed egg or not. CONSTITUTION:The white 2 is irradiated with ultraviolet rays from the black light 1, fluorescence of the yellow of its own emitted only when the yellow is contained is gathered by the condenser 3a, only the fluorescence of the yellow is transmitted by the optical filter 3b, and converted into an electrical signal by the receptor element 3c. The electrical signal is amplified by the amplifying circuit 4a, outputted to the comparative circuit 4b, compared with the set value by the setting part 4c of comparative value, and decision signal is sent to the output part 4d when the detected egg is decided as a disturbed egg. |
