EGG QUALITY INDEX EXAMINATION DEVICE

摘要

Light projecting means (2) and light receiving means (3) are so disposed that the exiting direction of a parallel light beam from the light projection means (2) is parallel to the entering direction of the parallel light beam into the light receiving means (3), and a reflector (11) and another reflector (12) are opposedly disposed on the optical path. The traveling direction of the parallel light beam emitted from the light projection means (2) is deflected by 90 degrees by the reflecting surface of the reflector (11). Thereafter, the traveling direction of the parallel light beam is further deflected by 90 degrees by the reflecting surface of the another reflector (12), and the parallel light beam enters the receiving means (3). The unit of the reflector (11) and the another reflector (12) moves horizontally with respect to a stage (1). With this, the Haugh unit and the yolk index which are egg-quality indexes can be contactlessly and automatically examined and the examination on the quality indexes can be made in a short time and with high accuracy.
