Abstract: An egg inspection apparatus to perform egg inspection based on the presence of adherence of protein to an eggshell is provided. According to the present invention, an egg inspection apparatus is provided that includes: a light radiating unit to radiate radiation light including an ultraviolet light component having a wavelength in an ultraviolet region to an eggshell surface of an egg subjected to inspection; a light receiving unit to receive reflection light reflecting from the eggshell surface out of the radiation light; and a determination unit to determine a state of adherence of protein to the eggshell surface based on the ultraviolet light component out of the reflection light received by the light receiving unit.

Abstract: A hatching egg inspection apparatus includes a loader unit, an inspection unit for determining the viability or the like as to whether a hatching egg is an unfertilized egg or a growth-stopping egg, a rejection unit for rejecting a hatching egg determined to be an unfertilized egg or the like, and an unloader unit for sending a hatching egg toward the next step. The inspection unit is provided with a light emitting unit for emitting prescribed light toward the hatching egg, a cap attachment unit through which the light having been emitted to the hatching egg and having transmitted through the hatching egg passes, and a light receiving unit for receiving the light that has passed through the cap attachment unit. The cap attachment unit includes a cylindrical cap coming into contact with the hatching egg, and a plate to which the cap is attached.

Abstract: As a means to enhance the reliability of a measurement system and render the measurement system tolerant of failure, the method which comprises tripling the component elements of the measurement system, for example, providing three thermometers to measure one and the same temperature and selecting a correct measured value by the logic of decision by majority has found popular recognition in the art. This method, however, entails many problems such as increased cost, increased weight, and increased volume because it necessitates the component elements thereof to be tripled.
