Title:
EGG QUALITY INDEX EXAMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/069263
Kind Code:
A1
Abstract:
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.
